Summary of Risk Factors 

We are providing the following summary of the risk factors contained in this Annual Report on Form 10-K to enhance the readability and accessibility of 
our risk factor disclosures. We encourage you to carefully review the full risk factors contained in this Annual Report on Form 10-K in their entirety for 
additional information regarding the material factors that make an investment in our securities speculative or risky. These risks and uncertainties include, 
but are not limited to, the following:

• We are a clinical-stage genetic medicines company with a history of losses, and we expect to continue to incur losses for the foreseeable future, and 

we may never achieve or maintain profitability.

• We will require substantial additional funding, which may not be available on acceptable terms, or at all.

•

•

Our management has broad discretion over the use of proceeds received from sales of our securities and our collaborations with third parties and the 
proceeds may not be used effectively.

Our short operating history may make it difficult for shareholders to evaluate the success of our business to date and to assess our future viability.

• We, or third parties upon whom we depend, may face risks related to health epidemics, including the COVID-19 pandemic and variants thereof, which 
may delay our ability to complete our ongoing clinical trials, initiate additional clinical trials, delay regulatory activities and have other adverse effects 
on our business and operations. 

•

The approach we are taking to discover and develop oligonucleotides is novel and may never lead to marketable products.

• We may not be able to conduct clinical trials successfully due to various process-related factors that could negatively impact our business plans.

•

•

•

If we cannot successfully manufacture our product candidates for our research and development and preclinical activities, or manufacture sufficient 
amounts of our product candidates to meet our clinical requirements and timelines, our business may be materially harmed.

Results of preclinical studies and early clinical trials may not be predictive of results of future clinical trials.

If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary regulatory approvals could be delayed or 
prevented.

• We may be unable to obtain regulatory approval in the United States or foreign jurisdictions and, as a result, be unable to commercialize our product 

candidates and our ability to generate revenue will be materially impaired.

•

•

Even if we obtain regulatory approvals, our marketed drugs will be subject to ongoing regulatory oversight. If we fail to comply with continuing U.S. 
and foreign requirements, our approvals, if obtained, could be limited or withdrawn, we could be subject to other penalties, and our business would be 
seriously harmed.

The pharmaceutical industry is intensely competitive. If we are unable to compete effectively with existing drugs, new treatment methods and new 
technologies, we may be unable to successfully commercialize any drugs that we develop.

4

 
•

Risks associated with our operations outside of the United States and developments in international trade by the U.S. and foreign governments could 
adversely affect our business.

• We may not be able to execute our business strategy optimally if we are unable to maintain our existing collaborations or enter into new collaborations 
with partners that can provide sales, marketing and distribution capabilities and funds for the development and commercialization of our product 
candidates.

• We rely, and expect to continue to rely, on third parties to conduct some aspects of our compound formulation, research, preclinical studies and 
clinical trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such formulation, 
research or testing.

•

•

•

If any of our product candidates are approved for marketing and commercialization and we are unable to develop sales, marketing and distribution 
capabilities on our own, or enter into agreements with third parties to perform these functions on acceptable terms, we will be unable to commercialize 
successfully any such future products.

If we are unable to attract and retain qualified key management and scientists, staff, consultants and advisors, our ability to implement our business 
plan may be adversely affected.

If we are not able to obtain and enforce market exclusivity for our technologies or product candidates, development and commercialization of our 
product candidates may be adversely affected.

• We license patent rights from third-party owners or licensees. If such owners or licensees do not properly or successfully obtain, maintain or enforce 
the patents underlying such licenses, or if they retain or license to others any competing rights, our competitive position and business prospects may 
be adversely affected.

•

•

Other companies or organizations may challenge our or our licensors’ patent rights or may assert patent rights that prevent us from developing and 
commercializing our products.

Intellectual property rights of third parties could adversely affect our ability to commercialize our product candidates, and we might be required to 
litigate or obtain licenses from third parties in order to develop or market our product candidates. Such litigation or licenses could be costly or not 
available on commercially reasonable terms.

• We are incorporated in Singapore and our shareholders may have more difficulty in protecting their interests than they would as shareholders of a 

corporation incorporated in the United States. 

• We are subject to the laws of Singapore, which differ in certain material respects from the laws of the United States. 

•

•

The public market may not be liquid enough for our shareholders to sell their ordinary shares quickly or at market price, or at all. 

The market price of our ordinary shares is likely to be highly volatile, and our shareholders may lose some or all of their investment.

Overview

PART I

We are a clinical-stage genetic medicines company committed to delivering life-changing treatments for people battling devastating diseases. Using 
PRISM, our proprietary discovery and drug development platform that enables the precise design, optimization, and production of novel stereopure 
oligonucleotides, we are working to develop first-or best-in-class medicines that target the transcriptome (the full set of ribonucleic acid, or “RNA,” 
molecules produced from the human genome) to treat genetically defined diseases with a high degree of unmet need. 

Our RNA-targeting oligonucleotides are designed to correct disease-causing mutations, modulate protein activity, restore the production of functional 
proteins or reduce the expression of disease-promoting RNAs or proteins. Data from our ongoing clinical and preclinical studies has demonstrated 
significant improvements in potency, durability, and distribution for our oligonucleotides designed through PRISM, compared with competitor chemistries. 
These data support our platform as best-in-class for designing and optimizing RNA-targeting medicines. 

Since our inception, we have seen the value of developing RNA-targeting medicines compared to other nucleic acid therapeutics, including gene therapy 
and DNA editing. By intervening at the RNA level, we have the potential to address diseases that have historically been difficult to treat with small 
molecules or biologics, while retaining the ability to titrate dose, modulate duration of effect, and avoid risk of permanent off-target genetic changes and 
other challenges associated with DNA editing or gene therapy approaches. Oligonucleotides have additional advantages as a therapeutic class, including the 
ability to access multiple tissue types and the ability to modulate the frequency of dosing to ensure broad distribution within tissues over time. 
Oligonucleotides also have well-established manufacturing processes and validated test methods based on decades of improvements, as well as established 
regulatory, access, and reimbursement pathways.

Our approach is based on the scientific insight that the biological machinery necessary to address genetic diseases already exists in human cells and can be 
harnessed for therapeutic purposes with the right tools. We have built a versatile platform comprised of multiple therapeutic modalities, which provides 
flexibility to design built-for-purpose molecules that optimally address disease biology. These modalities are RNA base editing, splicing, and silencing, 
including both RNA interference (“RNAi”) and antisense, all of which incorporate proprietary and novel chemistries to optimize the pharmacological 
properties of our therapeutic oligonucleotides. 

6

 
 
 
 
We have a robust and diverse pipeline of potential first-or best-in-class programs. Our lead programs are designed to treat genetic diseases, including those 
in muscle, including Duchenne muscular dystrophy (“DMD”); liver, including alpha-1 antitrypsin deficiency (“AATD”); and the central nervous system 
(“CNS”), including Huntington’s disease (“HD”), amyotrophic lateral sclerosis (“ALS”) and frontotemporal dementia (“FTD”). These programs include:

- WVE-N531 (splicing), our exon 53 molecule for the treatment of DMD; 

- WVE-006 (editing), our SERPINA1 molecule for the treatment of AATD; 

- WVE-003 (silencing), our mHTT SNP3 molecule for the treatment of HD; and

- WVE-004 (silencing), our C9orf72 molecule for the treatment of C9orf72-associated ALS and FTD.

Over the last several years, we have built a leading RNA base editing capability. Our A-to-I RNA base editing oligonucleotides (“AIMers”) enable access 
to areas of disease biology that are not viable for other therapeutic modalities. Our editing capability affords us the dexterity to address both rare diseases, 
as well as diseases impacting large patient populations. 

AIMers are designed to target single bases on an RNA transcript and recruit proteins that exist in the body, called ADAR (adenosine deaminases acting on 
RNA) enzymes, which naturally possess the ability to change an adenine (A) to an inosine (I), which cells read as guanine (G). This approach enables both 
the correction of G-to-A point mutations, as well as the modulation of RNA to upregulate protein expression, modify protein-protein interactions, or alter 
RNA folding and processing. AIMers enable simplified delivery and avoid the risk of permanent changes to the genome and irreversible off-target effects 
with DNA-targeting approaches. AIMers are short in length, fully chemically modified, and use novel chemistry, including proprietary PN backbone 
modifications and chiral control, which make them distinct from other ADAR-mediated editing approaches. 

Our PRISM platform was built on the recognition that a significant opportunity exists to tune the pharmacological properties of oligonucleotide 
therapeutics by leveraging three key features of these molecules: sequence, chemistry, and stereochemistry. Our unique ability to control stereochemistry 
provides the resolution necessary to optimize pharmacological profiles and develop and manufacture stereopure oligonucleotides. Stereopure 
oligonucleotides are comprised of molecules with atoms precisely and purposefully arranged in three-dimensional orientations at each linkage. These differ 
from the mixture-based oligonucleotides currently on the market or in development by others. Additionally, to mitigate pharmacological risks and potential 
manufacturing challenges, our approach focuses on designing short, chemically modified oligonucleotides without the need for complex delivery vehicles. 
We have also established and continue to enhance our internal cGMP (current good manufacturing practices) manufacturing capabilities to increase control 
and visibility of our drug substance supply chain, while continuing to innovate oligonucleotide manufacturing.

PRISM also incorporates our novel, proprietary PN backbone chemistry modifications, which have been shown preclinically and clinically to increase 
potency, distribution, and durability of effect across our various modalities. PN chemistry is incorporated in all of our current clinical, preclinical and 
discovery-stage programs.

In December 2022, we announced a strategic collaboration with GSK to advance transformative oligonucleotide therapeutics, including WVE-006. The 
collaboration combines GSK’s unique insights in human genetics, as well as its global development and commercial capabilities, with our PRISM platform 
and oligonucleotide expertise. The collaboration will enable us to continue building a pipeline of first-in-class oligonucleotide-based therapeutics and 
unlock new areas of disease biology, as well as realize the full value of WVE-006 as a potential best-in-class treatment for AATD that has the potential to 
simultaneously address both liver and lung manifestations of the disease. 

The GSK collaboration has three components:

1) A discovery collaboration which enables us to advance up to three programs leveraging targets informed by GSK’s novel insights;

2) A discovery collaboration which enables GSK to advance up to eight programs leveraging PRISM and our oligonucleotide expertise and 

discovery capabilities; and

3) An exclusive global license for GSK to WVE-006, our preclinical program for AATD that uses our proprietary AIMer technology. Wave will 

maintain development responsibilities for WVE-006 through completion of the first clinical study, at which point development and commercial 
responsibilities will transition to GSK.

Our Current Programs 

Additional details regarding our lead therapeutic programs are set forth below.

Duchenne muscular dystrophy (“DMD”)

In DMD, we are advancing WVE-N531, which is designed to skip exon 53 within the dystrophin gene – a therapeutic approach that would address 
approximately 8-10% of DMD cases. WVE-N531 is designed to cause the cellular splicing machinery to skip over this exon during pre-mRNA processing, 
which restores the dystrophin mRNA reading frame and enables production of truncated, but functional, dystrophin protein. Exon skipping produces 
dystrophin from the endogenous dystrophin gene (not micro or mini dystrophin expressed from a vector), under the control of native gene-regulatory 
elements, resulting in normal expression. WVE-N531 is both our first splicing candidate and our first systemically administered candidate incorporating 
PN chemistry to be assessed in the clinic. 

In December 2022 (data cut-off: December 6, 2022), we announced a positive update from Part A of the Phase 1b/2a proof-of-concept study of WVE-N531 
in three boys with DMD amenable to exon 53 skipping. High muscle concentrations of WVE-N531 and exon skipping were observed six weeks after 
initiating biweekly multi-dosing at 10 mg/kg, achieving proof-of-concept in the study. WVE-N531 also appeared safe and well-tolerated. 

To evaluate dystrophin protein restoration, we are initiating the Phase 2 portion of the WVE-N531 open-label study (“Part B”), and plan to enroll up to ten 
boys. Boys will be dosed at 10 mg/kg biweekly, and we plan to assess dystrophin protein after 24 and 48 weeks of dosing. The primary endpoint will be 
dystrophin protein levels, and the study will also evaluate pharmacokinetics, functional endpoints and safety and tolerability. We expect to initiate dosing in 
2023 and to deliver data in 2024. Based on results from this study, we would consider advancing a broader DMD pipeline with PN-modified splicing 
oligonucleotides for skipping other exons, with the goal of providing new treatment options for a larger population of boys with DMD. 

Alpha-1 antitrypsin deficiency (“AATD”) 

Our AATD program is the first to leverage our novel RNA editing capability and uses clinically proven N-acetylgalactosamine (“GalNAc”)-conjugated 
AIMers with subcutaneous dosing. By correcting the single RNA base mutation that causes a majority of AATD cases with the Pi*ZZ phenotype 
(approximately 200,000 in the U.S. and Europe), RNA editing may provide an ideal approach for increasing circulating levels of wild-type AAT protein 
and reducing mutant protein aggregation in the liver, thus simultaneously addressing both the lung and liver manifestations of the disease. 

In the third quarter of 2022, we announced WVE-006 as our development candidate for AATD. WVE-006 is first-in-class in AATD and is the most 
advanced program currently in development using an oligonucleotide to harness an endogenous enzyme for RNA editing. WVE-006 is currently in IND-
enabling studies, and we expect to submit clinical trial applications (CTAs) in the second half 

8

 
 
 
 
of 2023. Additionally, under the GSK collaboration, GSK received the exclusive global license for WVE-006, with clinical development and commercial 
responsibilities transitioning to GSK after we complete the first clinical trial. Under the terms of the collaboration, we are eligible to receive up to $525 
million in development, launch and sales-related milestones, as well as double-digit tiered royalties as a percentage of net sales up to the high teens, for 
WVE-006.

Preclinical data show that treatment with WVE-006 resulted in approximately 50% RNA editing of SERPINA1 transcript and approximately 7-fold greater 
AAT protein levels (well above the predicted protective threshold of 11uM) at 13 weeks in an established AATD mouse model (NSG-PiZ). WVE-006 also 
led to restoration of approximately 50% wild-type M-AAT protein in serum and a 3-fold increase in neutrophil elastase inhibition activity, indicating that 
the restored M-AAT protein was functional. Wave’s AATD AIMers are highly specific to SERPINA1 RNA in vitro and in vivo based on transcriptome-
wide analyses.

If we are successful in the clinic with WVE-006, we will both validate our clinical approach to AATD, as well as validate the feasibility of RNA editing in 
humans.

Huntington’s disease (“HD”)

In HD, we are currently advancing WVE-003, a stereopure antisense oligonucleotide designed to selectively target an undisclosed single nucleotide 
polymorphism (“SNP”), “mHTT SNP3”, associated with the disease-causing mutant huntingtin (“mHTT”) mRNA transcript within the Huntingtin 
(“HTT”) gene. Approximately 40% of the HD population carries SNP3 according to published literature (Carroll et al., Molecular Therapy, 2011).

WVE-003 incorporates our novel PN chemistry, as well as learnings from our first-generation HD programs. Targeting mRNA with SNP3 allows us to 
lower expression of transcript from the mutant allele, while leaving the healthy transcript relatively intact, thereby preserving wild-type (healthy) huntingtin 
(“wtHTT”) protein, which is important for neuronal function. Our allele-selective approach may also enable us to address the pre-manifest, or 
asymptomatic, HD patient population in the future. In preclinical studies, WVE-003 showed dose-dependent and selective reduction of mHTT mRNA in 
vitro, as well as potent and durable knockdown of mHTT mRNA and protein in vivo in mouse models. 

The SELECT-HD trial is a multicenter, randomized, double-blind, placebo-controlled Phase 1b/2a clinical trial to assess the safety and tolerability of 
intrathecally administered WVE-003 for patients with early manifest HD. Additional objectives include measurement of mHTT and wtHTT protein and 
exploratory pharmacokinetic, pharmacodynamic, clinical and magnetic resonance imaging (“MRI”) endpoints. The SELECT-HD trial is designed to be 
adaptive, with dose level and dosing frequency being guided by an independent committee. 

In September 2022 (data cut-off: August 29, 2022), we announced a positive update from SELECT-HD driven by the observation of reductions in mHTT 
protein in cerebrospinal fluid (“CSF”) after study participants received either a single 30 or 60 mg dose of WVE-003. Additionally, wtHTT protein levels 
appeared consistent with allele-selectivity. Single doses (30 mg, 60 mg, and 90 mg) of WVE-003 appeared generally safe and well-tolerated. Based on the 
SELECT-HD data, we have adapted the trial to expand the single dose cohorts, and we expect to share additional single-dose biomarker and safety data in 
the first half of 2023. 

C9orf72-associated amyotrophic lateral sclerosis and frontotemporal dementia (C9-ALS/FTD)

In ALS and FTD, we are advancing WVE-004, which uses our novel PN chemistry and preferentially targets the transcripts containing the hexanucleotide 
G4C2 expansion in the C9orf72 gene. Approximately 2,000 ALS patients and 10,000 FTD patients in the U.S. have this mutation in C9orf72. In C9 BAC 
transgenic mice, WVE-004 led to substantial reductions in repeat-containing C9orf72 transcripts and dipeptide repeat (“DPR”) proteins that are sustained 
for at least six months, without disrupting total C9orf72 protein expression. 

The FOCUS-C9 trial is a global, multicenter, randomized, double-blind, placebo-controlled Phase 1b/2a clinical trial to assess the safety and tolerability of 
intrathecal doses of WVE-004 for patients with C9-ALS and/or C9-FTD. Additional objectives include measurement of poly(GP) proteins in the CSF, 
plasma and CSF pharmacokinetics, and exploratory biomarker and clinical endpoints. The FOCUS-C9 trial is designed to be adaptive with dose level and 
dosing frequency being guided by an independent committee. 

In April 2022 (data cut-off: March 24, 2022), we announced a positive update from FOCUS-C9 driven by the observation of potent and durable reductions 
of poly(GP) dipeptide repeat proteins in CSF, a C9-ALS/C9-FTD disease biomarker that, when reduced in CSF, indicates WVE-004’s engagement of target 
in the brain and spinal cord. Based on the poly(GP) reduction data, the observation period for single dose cohorts was extended and additional patients 
were enrolled into the trial to further characterize the depth of knockdown, durability and longer-term safety profile. Additionally, we have initiated multi-
dosing cohorts, starting at 10 mg monthly and moving through 10 mg quarterly based on the potency and durability of pharmacodynamic effects. 
Additional single and 

9

 
multidose data are expected in the first half of 2023. Additionally, an open-label extension trial for FOCUS-C9 participants was initiated in the fourth 
quarter of 2022 and is ongoing.

Discovery Pipeline:

We are working to pursue new targets across multiple disease areas, given preclinical data indicating our oligonucleotides can distribute to various tissues 
and cells without complex delivery vehicles. We are also focusing on targets that have been genetically validated and offer biomarkers for target 
engagement to enable early proof-of-concept in the clinic. We expect this research to result in multiple new programs with first-in-class potential being 
added to our pipeline over the next several years. 

Our Strategy 

We are building a fully integrated genetic medicines company by leveraging PRISM to design, develop and commercialize optimized disease-modifying 
medicines for indications with a high degree of unmet medical need. We have a robust and diverse pipeline of PN-modified, stereopure oligonucleotides, 
including programs using our editing, splicing, and silencing modalities. Our lead clinical programs are focused in, and aim to address, muscle diseases 
(DMD - splicing), hepatic diseases (AATD – RNA editing), and CNS diseases (HD, ALS and FTD - silencing). In addition to driving clinical and 
preclinical programs, we are continuously investing in PRISM to fully unlock the potential of our unique and expanding platform capabilities. Additionally, 
we are conducting discovery research on multiple targets where we have the potential to deliver first-in-class therapeutics, starting with RNA editing.

The key components of our strategy are as follows: 

•

•

•

•

Extend our leadership in oligonucleotides. We intend to establish a dominant position in the field of oligonucleotides, advancing basic 
research and pharmacology using stereochemistry and novel modifications across multiple therapeutic modalities and target classes. Our 
work has already led to the development of AIMers for RNA base editing, as well as the introduction of PN backbone chemistry 
modifications for potential therapeutic use. Through PRISM, our efforts continue to reveal structure-activity relationships among sequence, 
chemistry and backbone stereochemistry that may allow us to further tune the activity of our oligonucleotides in a previously unexplored, 
modality-specific manner. 

Rapidly advance and sustainably grow our differentiated portfolio. We are committed to transforming the care of devastating diseases 
where patients have limited treatment options. Our current and future portfolio is focused on novel therapeutic approaches that optimally 
address disease biology and which offer biomarkers for target engagement to enable early proof-of-concept. We are currently advancing three 
clinical-stage candidates: WVE-N531, WVE-003 and WVE-004, which were all designed with novel PN backbone chemistry modifications 
developed from our PRISM platform. Additionally, we expect to file clinical trial applications (CTAs) for WVE-006 in 2023. We are also 
conducting our own discovery-stage research on novel therapeutic approaches, and additionally will have the opportunity through our GSK 
collaboration to advance programs leveraging GSK’s novel genetic and genomics insights. We expect these activities will add multiple first-
in-class therapeutics to our pipeline over the next several years. 

Expand our pipeline of high-value programs, starting with GalNAc-conjugated RNA editing. In 2022, we made meaningful progress in 
advancing our RNA base editing modality, (“AIMers”), including unlocking new applications beyond correction, such as upregulation. We 
also continued to optimize our RNAi capability for silencing and anticipate increasing our activities in RNAi. With these therapeutic 
modalities, we are positioned to develop first-in-class therapeutics, starting with hepatic indications that leverage GalNAc-conjugated 
delivery. 

Leverage manufacturing leadership in oligonucleotides. We have built a hybrid internal / external manufacturing model that gives us the 
capability to produce stereopure oligonucleotides at scales from one micromole to potential commercial scale. Through our internal 
manufacturing, based in our Lexington, Massachusetts facility, we have the capacity to support multiple discovery, preclinical, and early 
clinical-stage programs and have the established expertise to efficiently conduct manufacturing runs for oligonucleotides across a spectrum of
modalities. We believe that leveraging our internal manufacturing capabilities along with expertise from contract manufacturing 
organizations (“CMOs”) facilitates our growth and enhances our ability to secure drug substance for current and future development 
activities.

Oligonucleotides

Nucleic acid therapeutics, including oligonucleotides, are an innovative class of drugs that can modulate the function of target RNAs to ultimately affect 
the production of disease-associated proteins or prevent the accumulation of pathogenic RNA species, which are emerging as important factors in human 
disease. Oligonucleotides can regulate protein and RNA via several different molecular 

10

 
mechanisms. These mechanisms can be broadly categorized as RNA base editing; splicing, those that involve binding to the target RNA and modulating its 
function by promoting exon skipping; and silencing, those that promote degradation of the target RNA, including antisense and RNAi. 

The unique capability of oligonucleotides to address a wide range of genomic targets that impact multiple therapeutic areas creates potentially significant 
market opportunities for us to develop molecules to treat a broad spectrum of human diseases, including diseases where no medicines currently exist or for 
which existing treatments are not optimal. 

The investigational oligonucleotides we are currently developing employ the following molecular mechanisms: 

•

•

•

•

RNA base editing, which involves an oligonucleotide that uses endogenous ADAR (adenosine deaminases acting on RNA) enzymes to edit 
adenosines in target RNAs. This technology can be used to correct missense and nonsense mutations to restore protein activity. It can also be 
used to modulate protein activity, for example correcting a disease-causing mutation, altering a post-translational modification site, a protease 
cleavage site, or a protein-protein interaction interface. Other applications of this technology include the ability to target regulatory elements 
in RNA that impact its stability or function, for example, AUGs in the 5’-UTR for translational upregulation or AG splice acceptor sites to 
modify exon splicing. 

Splicing / exon skipping, which is the processing of a nascent pre-mRNA transcript into messenger RNA (“mRNA”) by removing introns 
and joining exons together. Exon skipping uses an oligonucleotide designed to bind to a particular sequence within a target pre-mRNA and 
direct the cellular machinery to delete, or splice out, certain specific regions of that RNA. Often, the underlying mutation leads to non-
productive mRNA, yielding no functional protein. Use of the exon-skipping modality permits the cellular machinery to bypass and assemble 
a partially functional protein, thereby mitigating or alleviating the disease that would otherwise result.

RNA interference (RNAi) (silencing), which uses double-stranded RNA to engage RNAi machinery known as the RNA-induced silencing 
complex (“RISC”) and to silence a target RNA that is either pathogenic itself or encodes a disease-associated protein, thereby preventing the 
accumulation of the pathogenic species (RNA or protein). 

Antisense (silencing), which uses an oligonucleotide designed to bind to a specific sequence in a target RNA strand that encodes a disease-
associated protein or pathogenic RNA. The resulting two-stranded molecule (“duplex”) is then recognized by a cellular enzyme called RNase 
H, which cleaves, or cuts, the target RNA in the duplex, thereby preventing the disease-associated protein from being made.

Stereochemistry of Oligonucleotide Backbone Modifications Impacts Pharmacology

Oligonucleotides are comprised of a sequence of nucleotides—the building blocks of RNA and DNA—that are linked together by a backbone of chemical 
bonds. In nucleic acid molecules that have not been modified for therapeutic use, the nucleotides are linked by phosphodiester (“PO”) bonds. Such 
unmodified nucleic acid molecules are unsuitable for use as therapeutics because they are rapidly degraded, rapidly cleared by the kidneys and taken up 
poorly by targeted cells. 

Backbone chemistry modifications such as the phosphorothioate (“PS”) modification, one of the most common backbone modifications used in 
oligonucleotides, can improve the stability, biodistribution and cellular uptake of oligonucleotides. 

A consequence of introducing backbone modifications, such as PS modifications, into an oligonucleotide is that it also introduces a chiral center at each 
phosphorus, creating stereoisomers designated as either an “Sp” or “Rp” isomer. As shown below, these stereoisomers have identical chemical 
compositions but different three-dimensional arrangements of their atoms and consequently have different chemical and biological properties. 

During traditional oligonucleotide synthesis, the isomeric configuration at each chiral backbone modification is random (either Rp or Sp), resulting in a 
complex mixture containing many stereoisomers (known as diastereomers). Using PS modifications as an example, each PS linkage introduces a chiral 
center, thereby doubling the number of stereoisomers in the product, so that a traditional preparation of a PS-containing oligonucleotide contains 2N 
stereoisomers, where N represents the number of PS modifications. 

Stereoisomers can possess different chemical and pharmacological properties. For example, certain stereoisomers can drive the therapeutic effects of a drug 
while others can be less beneficial or can even contribute to undesirable side effects. The greater the variation among a drug’s constituent stereoisomers, the 
greater the potential to diminish the drug’s efficacy and safety when it is a complex mixture. 

11

 
Prior to the development of our technology, it was not possible to create stereopure oligonucleotides – molecules where the configuration of each chiral 
backbone linkage is precisely controlled during chemical synthesis. Moreover, because of the sheer number of stereoisomers present in a mixture, it would 
be impractical, if not impossible, to physically isolate the most therapeutically optimal stereoisomer from within a mixture. For these reasons, all chiral 
backbone-modified oligonucleotides currently on the market and in development by others are mixtures of many stereoisomers, which we believe are not 
optimized for stability, catalytic activity, efficacy or toxicity. 

In small molecule therapeutics, U.S. regulators have long sought to eliminate the risks potentially posed by drug mixtures containing multiple 
stereoisomers. Since 1992, the FDA has recommended full molecular characterization of stereoisomers within small-molecule drug mixtures. Historically, 
it has not been possible to achieve such characterization for nucleic acid therapeutic drug mixtures, which can contain tens of thousands to millions of 
distinct pharmacological entities. Based on our published and ongoing clinical and preclinical studies, we believe that we can design and synthesize 
stereopure chemically modified oligonucleotides that demonstrate superior pharmacological properties compared with mixture-based oligonucleotides. We 
believe that PRISM has the potential to set a new industry standard for the molecular characterization of complex nucleic acid therapeutic drug mixtures. 

We continue to develop new types of backbone modifications, other than PS and PN modifications, that can be chirally controlled with our technology.

PRISM: Our proprietary discovery and drug development platform

Through PRISM, our proprietary discovery and drug development platform, we have discovered and expect to continuously elaborate on the relationships 
between the chemical makeup of an oligonucleotide, including the three-dimensional orientation or arrangement of its atoms, and its pharmacology (i.e., 
stability of the drug, activity against the target, specificity for the target and safety of the molecule). For example, we realized the impact of our novel PN 
backbone chemistry in vivo in preclinical studies when we evaluated its impact in the context of an otherwise stereopure backbone (Kandasamy et al., 
2022; doi: 10.1093/nar/gkac037, Kandasamy et al., 2022; doi: 10.1093/nar/gkac018). In addition, we have defined relationships between various 2’-sugar 
modifications to the nucleotide (such as methoxy, methoxyethyl, fluoro), and the chemistry and stereochemistry of the backbone that enhances 
oligonucleotide pharmacology, providing a potentially enhanced therapeutic profile. 

Our rational process for designing stereopure oligonucleotides, which is based on the interplay among oligonucleotide sequence, chemistry and backbone 
stereochemistry, allows us to selectively optimize for the therapeutic modality in order to generate best-in-class oligonucleotides. With PRISM, we leverage 
the diversity created by backbone stereochemistry to expand the parameters that we explore to optimize oligonucleotides. Moreover, through continued 
exploration of these interactions using iterative analysis of in vitro and in vivo outcomes and machine learning-driven predictive modeling, we also 
continue to refine our design principles that we deploy across subsequent programs. We are using these ongoing discoveries to guide our drug development 
activities, which we believe will lead to medicines that are more specific, can be dosed at lower concentrations, less frequently, or some combination of 
these characteristics as well as with improved therapeutic profiles. 

Advantages of Our Approach 

We believe that PRISM is a significant advancement in the development of oligonucleotides. The advantages of our approach include: 

•

•

•

Ability to rationally design product candidates with optimized pharmacological properties. Our platform combines our unique ability to 
construct stereopure oligonucleotides with a deep understanding of how the interplay among oligonucleotide sequence, chemistry and 
backbone stereochemistry impacts key pharmacological properties. By exploring these interactions through iterative analysis of in vitro and in 
vivo outcomes and machine learning-driven predictive modeling, we continue to define design principles that we deploy across programs to 
rapidly develop and manufacture clinical candidates that meet pre-defined product profiles. PRISM has also enabled us to further innovate our 
chemistry, including the application of novel PN backbone chemistry modifications to our pipeline programs. 

Broad applicability. PRISM is applicable to oligonucleotides acting via multiple therapeutic modalities, including RNA editing, splicing, and 
silencing (including RNAi and antisense). It is also compatible with a broad range of chemical modifications and targeting moieties. 

Simplified delivery. We can take advantage of simplified delivery strategies, such as free-uptake or GalNAc conjugation, to reach endogenous 
enzymes. This approach avoids the need, and certain limitations, for complex delivery vehicles such as lipid nanoparticles (“LNPs”) or adeno-
associated viruses (“AAV”).

Proprietary production of stereopure oligonucleotides. Our scientists have developed expertise in the techniques required to produce adequate 
supplies of chemically modified stereopure oligonucleotide materials for our preclinical and clinical activities. In addition, we believe we have 
the intellectual property position and know-how necessary to protect, advance and scale these production processes to support our clinical trials 
and potential future commercial supply. 

Scalability and manufacturing. Our manufacturing process and technical expertise in designing stereopure oligonucleotides is unique. We 
believe that our scalable synthesis processes will allow us to meet demand for cGMP-qualified clinical trial supply, as well as the potential for 
commercial manufacturing at a cost of goods and potential cost-per-patient that are comparable to stereorandom oligonucleotides.

Our Proprietary Chemistry 

Backbone Stereochemistry 

In our foundational Nature Biotechnology paper (Iwamoto N, et al. Nature Biotechnol. 2017;35(9):845-851), we described our studies using our proprietary 
chemistry to design and synthesize stereopure oligonucleotides and oligonucleotide mixtures based on mipomersen. Mipomersen, an oligonucleotide 
containing 20 nucleotides and 19 PS modifications, is synthesized by traditional oligonucleotide chemistry; thus, it is a mixture of over 500,000 different 
stereoisomers (219 = 524,288). We rationally designed and synthesized individual stereoisomers of mipomersen, each having position-specific and distinct 
stereochemistry, and conducted studies comparing these defined stereoisomers with the mipomersen stereomixture. These and other preclinical studies have 
demonstrated that stereochemistry and pharmacology are directly related, and that by controlling stereochemistry, we can impact multiple aspects of 
pharmacology, including stability, catalytic activity, efficacy, specificity, and safety. 

We have subsequently published multiple additional manuscripts that provide evidence that stereopure oligonucleotides can be developed to have superior 
pharmacology to stereorandom oligonucleotides. These manuscripts are listed below:

PN Backbone Chemistry Modifications

Our initial investigations into backbone chemistry and stereochemistry on oligonucleotide pharmacology focused on the widely used PO and PS backbones 
because they are amenable to all oligonucleotide modalities. In 2020, we announced the introduction of PN backbone chemistry modifications (“PN”) to 
our repertoire of backbone modifications, which involve replacing a non-bridging oxygen atom with a nitrogen-containing moiety, as shown below. 

We have incorporated these PN modifications – specifically phosphoryl guanidine – into oligonucleotide compounds. As with PS modifications, PN 
modifications are chiral, and we have the capacity to control PN backbone stereochemistry. Unlike PS modifications, PN modifications are neutral, 
meaning that the negative charge of the oligonucleotide is reduced with every PN modification added to the backbone. In preclinical experiments, we have 
demonstrated that judicious use of PN backbone chemistry modifications in stereopure oligonucleotides have generally increased potency, tissue exposure 
and durability of effect across our editing, splicing and silencing modalities.

PRISM Therapeutic Modality Types

Using PRISM, we have designed and optimized diverse sets of stereopure oligonucleotides, which allows us to characterize and compare the behavior of 
various stereoisomers. With each new target, we gain insight into how the interplay between sequence, chemistry, including 2’-modifications, backbone 
chemistry, and stereochemistry impacts activity, and we build these learnings into our future programs. 

In the next section, we describe different therapeutic modalities for which we have used PRISM to optimize stereopure oligonucleotides and develop built-
for-purpose candidates to optimally address disease biology. 

RNA base editing 

We have applied our PRISM platform to the generation of short, single-stranded, highly specific A-to-I (G) RNA-base editing oligonucleotides – called 
“AIMers”. Because our AIMers are relatively short and stable (fully chemically modified), we can leverage clinically proven GalNAc-mediated delivery to 
hepatocytes to further increase tissue uptake with subcutaneous dosing. We are developing fully chemically modified AIMers with and without GalNAc 
conjugation. In preclinical studies, we have evaluated thousands of AIMers, assessing a variety of sugar and base modifications, backbone chemistry and 
stereochemistry, and other parameters such as AIMer length to produce insight into the relationship between an AIMer’s structure and its ability to elicit 
RNA editing activity. 

14

 
 
 
 
With PRISM, we have generated stereopure AIMers, optimized for chemistry and stereochemistry, which promote RNA editing with endogenous 
adenosine deaminase acting on RNA (ADAR) enzymes in cellular models. As shown in the figure below, we show the activity of beta-actin-editing 
stereopure AIMers, with and without PN linkages, compared to a matched stereorandom AIMer (shown in black) in primary human hepatocytes. These 
AIMers are GalNAc conjugated to increase uptake in hepatocytes. The addition of PN chemistry substantially improves both potency and editing 
efficiency. 

In our Nature Biotechnology paper (Monian P, et. al., 2022; doi.org/10.1038/s41587-022-01225-1), we demonstrated efficient RNA editing in vitro with our 
AIMers across a variety of cell lines, including non-human primate and human primary hepatocytes, as shown in the figures below. We observed potent, 
dose-dependent RNA editing with three chemically distinct stereopure AIMers (ACTB 1, ACTB 2, ACTB 3) via GalNAc-mediated uptake. 

We next evaluated these same ACTB-editing AIMers in vivo in non-human primates (“NHPs”), and the results are shown in the figures below. For this 
study, we dosed NHPs subcutaneously once a day for five days. We took liver biopsy samples at baseline at two days and 45 days after the last dose to 
evaluate editing. We detected up to 50% editing two days after the last dose as compared to a baseline of 0% editing, as shown in the figure below on the 
left. These editing results were durable: we continued to see significant editing 45 days after the last dose. The pharmacokinetic data, shown in the figure 
below in the center, confirmed that a significant amount of AIMer was still detectable in the liver at that time. To assess off-target editing for the whole 
transcriptome, a mutation-calling software was used to call edit sites. From this analysis, we observed nominal off-target editing across the transcriptome. 
Sites 

15

 
 
 
 
 
 
 
where potential off-target editing occurred mapped predominantly to non-coding regions of the transcriptome and had either low read coverage in the 
analysis or occurred at low percentages of less than 10%, indicating that these are relatively rare events, as shown in the figure below on the right.

We have demonstrated potent (up to 65%) and durable (out to at least four months) editing of UGP2 mRNA in vivo in multiple regions of the CNS 
following a single unconjugated AIMer dose in a mouse model with human ADAR, as shown in the figure below. 

16

 
 
 
 
  
We have also observed productive editing beyond liver and CNS with unconjugated AIMers in multiple tissue types including the retina in mice (below top 
right), kidney, liver, lung and heart of NHPs (below bottom left), and human PBMCs in vitro (below bottom right).

We also observed potent, durable, and specific editing across multiple additional tissues following systemic administration of a single dose of an 
unconjugated UGP2 AIMer in mice. These additional tissues in mice include heart, kidney, lung, and spleen, as well as liver cells beyond hepatocytes. 

The application of PRISM to RNA editing opens the door to therapeutic applications extending beyond precise correction of genetic mutations, including 
upregulation of expression, modification of protein function, or alteration of protein stability. To date, we have achieved in vivo proof-of-concept 
modulating protein-protein interactions and upregulating protein expression. 

17

 
 
 
 
 
 
 
 
To exemplify our ability to modulate protein-protein interactions using ADAR, we evaluated the well characterized KEAP1/NRF2 system. Through direct 
protein-protein interactions, KEAP1 negatively regulates the activity of NRF2 as an inducer of antioxidant gene expression. As a proof-of-concept 
experiment, we investigated if we could mimic the cellular stress response by using ADAR to edit individual amino acids at the protein-protein interaction 
interface between NRF2 and KEAP1 in vivo in mice. If these edits work as designed, we would expect to see downstream upregulation of the NRF2-
dependent gene expression program even in the absence of cellular stressors. As shown below, treatment with AIMers resulted in increased expression of 
known downstream NRF2-dependent genes involved in the antioxidant response. Control treatment did not increase expression of any of the NRF2-
dependent genes, indicating that AIMer treatment did not lead to NRF2-dependent gene expression changes through non-specific mechanisms such as 
increased cellular stress.

To exemplify our ability to upregulate protein expression levels using ADAR, we evaluated AIMers designed to modify regulatory elements in RNA that 
mediate protein-RNA or RNA-RNA interactions. Specific structural or sequence motifs that mediate these intermolecular interactions impact RNA 
processing and stability. As a proof-of-concept experiment, we investigated whether modification of these regulatory elements could increase protein 
expression in the mouse liver. If these edits work as designed, we would expect to see upregulation of both mRNA and protein. As shown below, treatment 
of mice with GalNAc-AIMers resulted in editing of the target mRNA in liver, increased levels of the transcript in liver, and increased serum protein levels 
one week after dosing. These data demonstrate that AIMers designed to edit protein-RNA or RNA-RNA interaction motifs can be applied to increase 
protein expression.

18

 
 
 
 
 
 
 
Splicing

With PRISM, we have optimized stereopure oligonucleotides that promote efficient splicing in vitro, ex vivo, and in vivo to restore protein production. In 
our splicing programs, as with our other modalities, the sequence, chemistry and backbone stereochemistry of oligonucleotides impact their activity. 

In our Nucleic Acids Research paper (Kandasamy et al., 2022; doi: 10.1093/nar/gkac018), we highlight the impact of PN chemistry on exon skipping. In 
one application from the paper, we plotted the in vitro skipping efficiency of compounds containing PS / PO backbone chemistry modifications, depicted in 
the graph below by the teal dots, which are rank-ordered from left-to-right based on their exon-skipping potency in human myoblasts. The more potent 
molecules are shifted upwards as they are restoring expression. The navy dots represent the impact of a few stereopure PN modifications in compounds 
with otherwise identical sequences and 2’-ribose chemical modifications. There is an overall shift upwards in activity among the PS / PO / PN compounds, 
representing a substantial potency gain in most cases. 

19

 
 
 
 
 
 
 
Moving in vivo, we demonstrated successful exon skipping in double knockout mice (“dKO”), which lack both utrophin and dystrophin and therefore 
develop a severe muscular dystrophy phenotype comparable to that observed in patients with DMD. In these mice, exon skipping correlated with 
dystrophin protein expression, and PN-modified oligonucleotides led to more exon skipping and dystrophin production in all muscles examined after six 
weeks of treatment (shown below, left). Exon skipping and dystrophin expression improvements correlated with improved serum biomarker profiles in the 
same mice (shown below, right). These results demonstrate the impact of the judicious placement of PN linkages – with no delivery vehicle or conjugate – 
which can significantly improve the pharmacological profiles for stereopure compounds. 

Data adapted from Figure 8, Kandasamy et al., 2022; doi: 10.1093/nar/gkac018 (Stats: One-way ANOVA: *P<0.05, **P<0.01, ***P<0.001, 
****P<0.0001)

Silencing – RNAi and RNase H-mediated degradation 

Using PRISM, we can produce stereopure PN-modified oligonucleotides that promote potent and specific RNA transcript silencing activity in preclinical 
experiments. 

RNAi: We have applied our stereopure PS and PN modifications to the RNAi modality using double-stranded siRNAs and demonstrated potent and durable 
silencing in vivo in transgenic mice. We once again leverage GalNAc to enhance delivery to liver hepatocytes. The data, shown below, illustrate a GalNAc-
siRNA, with controlled stereochemistry and PN backbone chemistry, that led to remarkably durable transcript silencing in mice three months after a single 
dose, compared with mice treated with a siRNA 

20

 
 
based on state-of-the-art designs, where expression levels had recovered to control levels (left). The data below (middle and right) also highlight that 
siRNAs developed with PRISM show improved activity profiles because they support more Ago2 loading than controls. 

Additionally, in our first in vivo non-GalNAc siRNA study, we demonstrated that our unconjugated siRNA constructs led to 70-90% APP silencing across 
six brain regions in mouse CNS at 8 weeks, following a single intracerebroventricular (ICV) dose.

RNase H-mediated degradation (antisense): In our Nucleic Acids Research paper (Kandasamy et al., 2022; doi: 10.1093/nar/gkac018), we illustrated the 
impact of PN backbone chemistry modifications for an RNase-H mediated silencing modality. In addition to the data reported in the paper, we have 
performed screens for identifying RNase H-targeting sequences in iCell neurons in vitro using free uptake. This screen was initially performed with 
stereopure molecules with PS and PO backbone chemistry modifications, and the oligonucleotides are rank-ordered from left to right according to their 
potency. Next, we performed a head-to-head comparison with molecules that contained the same sequence and the same 2’-ribose chemistry, but with the 
addition of PN chemistry at select locations in the backbone. The introduction of a few PN linkages significantly increases the potency of the vast majority 
of the stereopure PS / PO molecules, with ~80% of them yielding at least 75% knockdown. These results, shown below, suggest we are able to target 
sequence space that would otherwise be inaccessible. 

21

 
 
 
 
 
Moving in vivo, we have demonstrated potent silencing activity of multiple targets in the CNS of non-human primates with stereopure, PN-modified 
oligonucleotides. In the results shown below, non-human primates received a single 12 mg dose by intrathecal injection. This single dose led to substantial 
and widespread mRNA reduction in the CNS one month after administration. 

Therapeutic Programs 

Our clinical-stage therapeutic programs include a splicing program for protein restoration in muscle – WVE-N531 for DMD, and two silencing programs 
for indications in the CNS – WVE-003 for HD and WVE-004 for ALS / FTD. In 2022, we also selected a development candidate and initiated IND-
enabling toxicology studies for our first RNA editing program, WVE-006, which leverages GalNAc-conjugated delivery for AATD.

22

 
 
 
 
 
  
 
 
 
See below for more information on these programs and the diseases we are targeting. 

Duchenne Muscular Dystrophy

Background and Market Opportunity

DMD is a rare, genetic progressive neuromuscular disorder caused by mutations in the dystrophin gene on the X chromosome that affects approximately 
one in 5,000 newborn boys around the world (approximately 20,000 new cases annually). The dystrophin protein is part of a protein complex called the 
dystrophin-associated protein complex that acts as an anchor, connecting each muscle cell’s structural framework with a lattice of proteins and other 
molecules outside the cell through the muscle cell membrane. The dystrophin-associated protein complex protects the muscle from injury during 
contraction and relaxation. Patients with DMD typically develop muscle weakness in the early years of life and become wheelchair-bound in their early 
teens. As the disease progresses, DMD patients typically develop respiratory, orthopedic, and cardiac complications. Cardiomyopathy and breathing 
difficulties usually begin by the age of 20, and few individuals with DMD live beyond their thirties.

Current Treatments

While there are approved therapies for DMD, there is no cure, and there continues to be significant unmet medical need. In most countries, corticosteroids 
are the standard drug therapy, which slows the progression of muscle weakness and delays loss of ambulation by two to three years. In February 2017, 
Emflaza (deflazacort) became the first corticosteroid in the United States approved by the FDA as a treatment for DMD patients older than five years of 
age.

In 2016, Sarepta Therapeutics’ Exondys 51™ (eteplirsen) received accelerated approval in the United States for the treatment of patients with DMD, who 
have a confirmed mutation of the dystrophin gene amenable to exon 51 skipping. Two drugs have received accelerated approval in the United States for 
DMD patients with a confirmed mutation of the dystrophin gene amenable to exon 53 skipping: Sarepta Therapeutics’ Vyondys 53™ (golodirsen) in 2019 
and NS Pharma’s Viltepso™ (viltolarsen) in 2020. NS Pharma has also received Marketing Authorization for Viltepso in Japan. In 2021, Sarepta’s 
Amondys 45™ (casimersen) received accelerated approval for DMD patients with a mutation amenable to exon 45 skipping. According to U.S. accelerated 
approval guidelines, approval is based on a surrogate endpoint that is likely to predict clinical benefit, but no clinical benefit needs to be established at the 
time of FDA approval. No clinical benefit has yet been established for eteplirsen, golodirsen, viltolarsen, or casimersen. Thus, in accordance with the U.S. 
accelerated approval regulations, the FDA is requiring Sarepta to conduct clinical trials to verify and describe the clinical benefit of eteplirsen, golodirsen, 
and casimersen. Similarly, NS Pharma is required to conduct a clinical trial to verify and describe the clinical benefit of viltolarsen. If any of these 
confirmatory trials fail to verify clinical benefit, the FDA could initiate proceedings to withdraw approval of the respective drug(s). 

In 2014, PTC Therapeutics’ Translarna™ (ataluren) was the first disease-modifying treatment to receive conditional approval by the European Medicines 
Agency (“EMA”) for the treatment of ambulatory DMD patients over 5 years of age who have a nonsense mutation (12% of DMD cases) in the dystrophin 
gene. In 2016, the EMA did not allow Translarna to convert to full marketing authorization; rather, it granted a renewal of the conditional approval. In 
2018, EMA expanded the conditional approval for Translarna to include treatment of ambulatory DMD patients ≥2 years of age who have a nonsense 
mutation in the dystrophin gene. In June 2020, the EMA removed a statement from the summary of product characteristics (“SmPC”) for Translarna that 
“efficacy has not been demonstrated in non-ambulatory patients.” 

Our DMD Program

WVE-N531: In DMD, we are advancing WVE-N531, which is designed to skip exon 53 within the dystrophin gene. WVE-N531 is designed to cause the 
cellular splicing machinery to skip over this exon during pre-mRNA processing, which restores the dystrophin mRNA reading frame and enables 
production of truncated, but functional dystrophin protein. Exon-skipping produces dystrophin from the endogenous dystrophin gene (not micro or mini 
dystrophin expressed from a vector), under the control of native gene-regulatory elements, resulting in normal temporospatial expression. WVE-N531 is 
both our first splicing candidate and our first systemically administered candidate incorporating PN chemistry to be assessed in the clinic. 

WVE-N531 clinical trial: In December 2022 (data cut-off: December 6, 2022), we announced a positive update from Part A of the Phase 1b/2a proof-of-
concept study for WVE-N531 in DMD. This was an open-label, intra-patient dose escalation clinical trial where three boys received single escalating doses 
of 1, 3, 6 and 10 mg/kg; in the multidose portion of the study, the same boys received three doses of 10 mg/kg every other week. A muscle biopsy was 
taken two weeks after the third and final dose (six weeks after the first dose). 

23

 
WVE-N531 resulted in a mean tissue concentration of 42 micrograms/gram (6.1 micromolar), and RNAscope results indicated WVE-N531 is reaching the 
nucleus in muscle cells. WVE-N531 resulted in mean exon skipping of 53% (range: 48-62%) as measured by RT-PCR. Mean dystrophin production was 
0.27% of normal as measured by western blot, which was below the level of quantification (BLQ: 1%). While dystrophin was below the lower limit of 
detection, it is expected that dystrophin protein production would lag splicing of the RNA transcript. Plasma concentrations and other pharmacokinetic 
parameters following a single dose of 10 mg/kg demonstrate a half-life of 25 days. Adverse events were all mild, except for a COVID-19 infection of 
moderate intensity. There were no serious adverse events, no trends in labs, and no oligonucleotide class-related safety events. 

Based on these data, we plan to initiate the Phase 2 portion of the WVE-N531 open-label study (“Part B”) to enroll up to ten boys to assess dystrophin 
protein restoration. Boys will be dosed at 10 mg/kg biweekly, and we plan to assess dystrophin protein after 24 and 48 weeks of dosing. The primary 
endpoint will be dystrophin protein levels, and the study will also evaluate pharmacokinetics, functional endpoints and safety and tolerability. We expect to 
initiate dosing in 2023 and to deliver data in 2024.

Preclinical data

In vitro, WVE-N531 induced dose-dependent exon 53 skipping up to 49% and dystrophin protein restoration up to 71% in DMD patient-derived myoblasts 
carrying a deletion of exons 45-52. In these experiments, cells were exposed to WVE-N531 at 0.1 µM-10 µM under gymnotic conditions. After four days 
of oligonucleotide treatment, efficiency at skipping exon 53 was determined by quantitative RT-PCR. After six days of oligonucleotide treatment, protein 
lysate was analyzed by western blot for dystrophin protein expression.

In NHPs, plasma and tissue concentrations of WVE-N531 were significantly higher than suvodirsen (our first-generation PS/PO). WVE-N531 
concentrations in heart and diaphragm were substantially higher than skeletal muscle concentrations. We also observed higher plasma Cmax, AUC and 
Ctrough levels compared with suvodirsen.

To understand the effects of PN backbone chemistry modifications in vivo, we conducted a study in a dKO mouse model, which has a mutation in exon 23 
leading to a lack of dystrophin, as well as a mutation leading to a lack of utrophin. We compared the effects of a PS/PO-containing molecule dosed at 150 
mg/kg weekly to a PN-containing compound dosed at the same level, a PN-containing compound at 75 mg/kg every other week and a control group dosed 
with PBS. Other than the placement of the three PN backbone linkages, these molecules have the same sequence and chemistry. There is a significant 
increase in survival in those animals treated with PN containing compounds as compared with the other treatment groups. As shown in the figure below, 
both cohorts of mice receiving the PN-containing molecules (shown in dark blue and light green) had 100% survival at the time of study termination, with 
a median age of approximately 40 weeks. By comparison, the median survival for the mice receiving the PS/PO-containing molecule dosed at 150 mg/kg 
weekly was approximately 12 weeks and the dKO control animals that received PBS had a median survival of 

24

 
  
 
 
approximately seven weeks. These results were published in Nucleic Acids Research (Kandasamy et al., 2022; doi: 101.1093/nar/gkac018).

Alpha-1 Antitrypsin Deficiency

Background and Market Opportunity

We are leveraging our RNA editing platform capability to develop a potentially novel treatment for AATD. AATD is a rare, inherited genetic disorder that 
is commonly caused by a G-to-A point mutation in the SERPINA1 gene; this mutant allele is termed the Z allele. This mutation leads to misfolding and 
aggregation of alpha-1 antitrypsin (“AAT”) protein in hepatocytes and a lack of functional AAT in the lungs. People with AATD typically exhibit 
progressive lung damage, liver damage or both, leading to frequent hospitalizations and potentially terminal lung disease and/or liver disease. While the 
few approved therapies for AATD modestly increase circulating levels of AAT in those with the lung pathology, there are no approved therapies to address 
the liver pathology. Approximately 200,000 people in the United States and Europe are homozygous for the Z allele, which is the most common form of 
severe disease. 

Current Treatments

There are five treatments currently approved in the United States for chronic augmentation and maintenance therapy in adults with emphysema due to 
congenital deficiency of alpha1-proteinase inhibitor (Alpha1-PI). Per FDA labeling for each, the effect of augmentation therapy with any alpha1-proteinase 
inhibitor on pulmonary exacerbations and on the progression of emphysema in Alpha1-PI deficiency has not been demonstrated in randomized, controlled 
clinical trials. Patients with AATD can also be treated with therapies used in other lung diseases including bronchodilators to open airways and 
corticosteroids to reduce chronic inflammation common in the lungs of AATD patients.

There are currently no approved therapies to prevent the accumulation of the misfolded AAT protein in the liver. Treatments are available to help deal with 
intestinal bleeding, fluid in the abdomen, nutritional issues, and other complications from scarring of the liver, but ultimately many patients will progress 
towards requiring a liver transplant. 

Our AATD Program

Our AATD program is the first to leverage our novel RNA editing capability that uses GalNAc-conjugated AIMers (RNA base editing oligonucleotides) 
and endogenous ADAR enzymes by correcting a single base in the mutant SERPINA1 mRNA. ADAR editing may provide an ideal approach for 
increasing circulating levels of wild-type AAT protein and reducing aggregation in the liver, thus simultaneously addressing both the lung and liver 
manifestations of the disease. In the third quarter of 2022, we announced WVE-006 as our development candidate for AATD. WVE-006 is first-in-class in 
AATD and will be administered using subcutaneous administration. It is the most advanced program currently in development using an oligonucleotide to 
harness an endogenous enzyme for RNA base editing. WVE-006 is currently in IND-enabling studies and we expect to submit clinical trial applications in 
the second half of 2023.

25

 
 
 
Preclinical data

Preclinical data for WVE-006 demonstrated that WVE-006 supports dose-dependent RNA editing in human preclinical model systems, as shown in the 
figure below. We observed efficient SERPINA1 editing in donor-derived primary human hepatocytes (MZ genotype) after 48 hours, as well as a dose-
dependent increase in RNA editing in iPSC-derived human hepatocytes (ZZ genotype) eight days after a single dose.

In an in vivo preclinical study in NSG-PiZ mice, we demonstrated restoration of functional AAT protein with bi-weekly doses of 10 mg/kg. At 13 weeks, 
AAT protein levels with WVE-006 were approximately 7-fold greater than PBS-administered controls and well above the predicted protective threshold of 
11 uM, as shown below (left). This increase was observed at week 13 both in mice that received a loading dose, as well as mice that did not. WVE-006 also 
resulted in approximately 50% RNA editing of SERPINA1 transcript at 13 weeks in this same model, regardless of whether a loading dose was used, as 
shown below (right).

26

 
 
 
 
 
 
We then sought to determine whether the restored serum AAT protein from the mouse experiment described above was wild-type M-AAT protein. WVE-
006 led to restoration of approximately 50% wild-type M-AAT protein in serum, as measured by mass spectrometry, as shown below (left), as well as a 3-
fold increase in neutrophil elastase inhibition activity, as shown below (right), indicating the restored M-AAT protein was functional. 

An earlier lead (pre-optimization) GalNAc-AIMer reduced Z-AAT aggregates and inflammation in mouse livers (mouse model: huADARxSA1), as 
indicated below. 

27

 
 
 
 
 
 
 
 
 
To evaluate the specificity of our GalNAc-AIMers (specifically “SA1-4 AIMer”), we performed RNA-seq on liver biopsies from treated animals. The 
figure below on the left shows total sequence coverage across the entire SERPINA1 transcript for the AIMer-treated samples. The percentage of unedited 
“T” and edited “C” reads are indicated for each group. Editing is only detected at the intended, on-target sequence in the SERPINA1 transcript. Thus, the 
protein being produced using this approach is truly wild-type M-AAT protein. This also confirms there is no editing of bystander residues, as has been seen 
with DNA targeting approaches. To assess off-target editing for the whole transcriptome, we applied a mutation-calling software to search edit sites. From 
this analysis, we observed minimal off-target editing across the transcriptome. Sites where potential off-target editing occurred had either low read 
coverage in the analysis or occurred at low percentages (less than 10%), indicating that these are rare events, as shown below on the right. In both analyses, 
we find a high percentage of editing that is specific for the target site in the SERPINA1 transcript.

Huntington’s Disease 

Background and Market Opportunity 

Huntington’s Disease (“HD”): HD is a rare hereditary neurodegenerative disease that results in early death and for which there is no cure. In HD patients, 
there is a progressive loss of neurons in the brain leading to cognitive, psychiatric, and motor disabilities. HD is caused by a defect (an expanded CAG 
triplet repeat) in the HTT gene, which results in production of mutant HTT (“mHTT”) protein. HD patients still possess some wild-type (healthy) HTT 
(“wtHTT”) protein, which is important for neuronal function, and which may 

28

 
 
 
 
 
 
be neuroprotective in an adult brain. Studies suggest a multifaceted mechanism by which gain of mHTT protein and a concurrent loss of wtHTT protein 
may drive the pathophysiology of HD. Accordingly, therapeutic approaches for HD that aim to lower mHTT but that also suppress wtHTT may have 
detrimental long-term consequences. Wild-type HTT is important both for normal neuronal function in the adult CNS and for protection against HD. It can 
protect against stress-induced neurodegeneration in multiple model systems: in cultured neurons, wtHTT is protective against stress-induced apoptosis; in 
mice, postnatal deletion of wtHTT leads to progressive neurological phenotypes, neurodegeneration, and premature death, whereas overexpression of 
wtHTT conveys neural protection during stress, including ischemia and other types of CNS injury, as well as NMDA-induced excitotoxicity. In the 
YAC128 mouse model of HD, overexpression of wtHTT ameliorates striatal neuropathology, whereas loss of the wild-type mouse HTT worsens motor 
performance, survival, and striatal neuronal size. In patients with HD, the A variant of a non-coding single nucleotide polymorphism (“SNP”) disrupts a 
binding site for the transcription factor NF-κB and decreases expression of the associated HTT gene: when the A variant associates with mHTT, disease 
onset is late (on average, 10-years later than when the G variant associates with mHTT); when the A variant associates with wtHTT, disease onset is earlier 
(on average, four years earlier than when the G variant associates with wtHTT), indicating that increased expression of wtHTT can be protective against 
HD in patients. Together, these studies provide evidence that wtHTT is both neural protective during stress and is specifically protective against HD; thus, 
we believe an allele-selective therapeutic, one that can diminish the production of mHTT while sparing wtHTT, may be ideal. 

Symptoms of HD typically appear between the ages of 30 and 50 and worsen over the next 10 to 20 years. Many describe the symptoms of HD as similar 
to having amyotrophic lateral sclerosis, Parkinson’s Disease and Alzheimer’s Disease simultaneously. Patients experience a reduction in motor function and 
psychological disturbances. Life expectancy after symptom onset is approximately 20 years. In the most symptomatic stages, often lasting over 10 years, 
affected persons become fully dependent upon others to manage all activities of daily living; they lose the ability to make decisions, feed themselves and 
walk, and often require premature placement in a long-term care facility. It is estimated that approximately 30,000 people in the United States have 
symptomatic HD. Our allele-selective approach may also enable us to address the pre-manifest, or asymptomatic, HD patient population in the future. More 
than 200,000 people in the United States are at-risk of developing HD. 

Current Treatments 

There are no approved treatments that can reverse or slow HD progression. Current pharmacological therapies only address HD symptoms. Antipsychotics 
are used to manage depression, irritability, and chorea (involuntary movements). Xenazine (tetrabenazine) and Austedo (deutetrabenazine) are the only two 
therapies approved for the treatment of chorea associated with HD in the United States. In the EU, Xenazine, Haldol (haloperidol), and Tiapridal (tiapride) 
are approved for the treatment of chorea associated with HD. 

Our HD Program

WVE-003: In HD, we are currently advancing WVE-003, a stereopure antisense oligonucleotide designed to selectively target an undisclosed SNP, “mHTT 
SNP3”, associated with the disease-causing mutant huntingtin (“mHTT”) mRNA transcript within the HTT gene. SNPs are naturally occurring variations 
within a given genetic sequence and in certain instances can be used to distinguish between two related copies of a gene where only one is associated with 
the expression of a disease-causing protein. Approximately 40% of the HD population carries SNP3 according to published literature (Carroll et al., 
Molecular Therapy, 2011). WVE-003 incorporates our novel PN chemistry, as well as learnings from our first-generation HD programs. Targeting mRNA 
with SNP3 allows us to lower expression of transcript from the mutant allele, while leaving the healthy transcript relatively intact. The healthy transcript 
produces wtHTT protein, which is important for neuronal function. We commonly refer to this method (or approach) as “allele-selective targeting.” Our 
allele-selective approach may also enable us to address the pre-manifest, or asymptomatic, HD patient population in the future. 

29

 
 
In preclinical studies, WVE-003 showed dose-dependent and selective reduction of mHTT mRNA in vitro, and potent and durable knockdown of mHTT 
mRNA and protein in vivo. A pharmacokinetic-pharmacodynamic (PK-PD) model for WVE-003 based on preclinical data predicts that WVE-003 may 
attain sufficient concentrations to engage mHTT transcript in both the cortex and striatum and decrease expression of mHTT protein.

SNP Phasing Technology: To verify that potential HD patients have a heterozygous SNP with the right variant in-phase with the mutant allele, we 
investigated multiple technologies that could provide highly accurate results and rapid turnaround. We conducted a prospective observational study of the 
frequency of two SNPs in patients with HD, which confirmed the feasibility of rapidly and prospectively identifying SNPs in association with the mHTT 
allele in patients with HD (Claassen et al., Neurol Genet 2020; Svrzikapa et al., Molecular Therapy 2020). We have an agreement with Asuragen, Inc. 
(“Asuragen”), a molecular diagnostics company that was acquired by Bio-Techne Corporation in April 2021, for the development and potential 
commercialization of companion diagnostics for our allele-selective therapeutic program in HD. This agreement includes the use of their scalable SNP 
phasing technology (AmplideX® HTT SNP/Repeat Phasing Clinical Trial Assay) in our SELECT-HD trial for WVE-003. 

SELECT-HD Phase 1b/2a clinical trial: The SELECT-HD trial is a multicenter, randomized, double-blind, placebo-controlled Phase 1b/2a trial to assess 
the safety and tolerability of intrathecally administered WVE-003 for patients with early manifest HD. Additional objectives include measurement of CSF 
mHTT and wtHTT protein and exploratory pharmacokinetic, pharmacodynamic, clinical and MRI endpoints. The SELECT-HD trial is designed to be 
adaptive, with dose level and dosing frequency being guided by an independent committee. Preclinical models that have established pharmacologic activity 
have informed the starting dose for this trial. 

In September 2022 (data cut-off: August 29, 2022), we announced a positive update from SELECT-HD, with initial results indicating allele-selective target 
engagement with WVE-003 in HD. Single doses of WVE-003 up to 90 mg appeared generally safe and well-tolerated. Among participants in the 30 and 60 
mg WVE-003 cohorts, the mean reduction in CSF mHTT from baseline was 22% (median reduction 30%) at 85 days following a single dose. Participants 
in the 90 mg cohort had not yet reached day 85, so they were not included in the biomarker analysis. The difference in the mean reduction in CSF mHTT 
compared to placebo was 35% at 85 days post-single dose. For these analyses, the 30 and 60 mg single dose cohorts were pooled as there was no apparent 
dose response between these two cohorts. In the 30 and 60 mg cohorts, wtHTT protein levels appeared consistent with allele-selectivity. Increases in 
neurofilament light chain (“NfL”) from baseline were observed in some participants. There were no clinically meaningful elevations in CSF white blood 
cell counts or protein that would indicate inflammation in the CNS, and there were no meaningful changes in clinical outcome measures, although the 
dataset and duration were not sufficient to assess clinical effects.

Based on the SELECT-HD data, we have adapted the trial to expand the single dose cohorts and expect to share additional single-dose biomarker and safety 
data in the first half of 2023.

Preclinical studies

WVE-003 showed potent knockdown of HTT mRNA in a preclinical study using induced pluripotent stem cell (“iPSC”)-derived motor neurons 
homozygous for SNP3 (as shown below). 

30

 
 
 
 
WVE-003 promoted RNase H–mediated degradation of mHTT RNA while sparing wtHTT RNA in a biochemical assay. 

We further demonstrated selectivity of WVE-003 in assays performed in induced pluripotent stem cell (iPSC) neurons from patients with HD that are 
heterozygous for SNP3. WVE-003 selectively silenced the mutant transcript while largely sparing the wild-type transcript. By comparison, the pan-
silencing active comparator silenced both mutant and wild-type HTT transcripts. 

31

 
 
 
 
 
We next tested our SNP3 compounds in vivo in a BACHD model for HD. This model expresses a mutant version of the human HTT gene. Because it is a 
transgenic model that lacks human wtHTT, BACHD mice are not suitable for assessing selectivity, but they enable assessment of target engagement in vivo. 
Importantly, the model contains multiple copies of the human mHTT transgene; however, not all of the copies contain SNP3. Thus SNP3-targeting 
compounds cannot target all the human mHTT transcripts expressed in these mice. After administration, WVE-003 showed significant mHTT mRNA 
knockdown compared with phosphate-buffered saline (PBS) at the highest concentration tested in the striatum and all but the lowest concentration tested in 
the cortex. WVE-003 showed comparable reduction of mHTT mRNA to that of the pan-silencing oligonucleotide, despite having fewer targets in these 
mice.

In the cortex of BACHD mice, WVE-003 showed significant mHTT knockdown compared to PBS through week four. In the striatum, WVE-003 led to 
significant and durable mHTT knockdown that was sustained for 12 weeks, compared with PBS. WVE-003 led to significantly more knockdown than the 
pan-silencing reference compound at week 12 in the striatum. Since most but not all of the transgenes in this model contain SNP3, our SNP3 compounds 
are disadvantaged versus the pan-silencing active comparator.

In vivo allele-selectivity: We then tested in vivo allele-selectivity using an allele-selective mHTT SNP3 targeting oligonucleotide in a humanized mouse 
model (“Hu97/18”). The mice express a human YAC wtHTT transgene (with 18 CAG repeats) and a human BAC mHTT transgene (with 97 CAG repeats). 
The mice carry the SNP3 variant associated with the human mHTT allele, and they do not 

32

 
 
 
 
 
express mouse huntingtin. After administration (3 x 100 ug ICV doses), the allele-selective molecule decreased mHTT and spared wtHTT in the cortex, 
striatum, and hippocampus of Hu97/18 mice up to 12 weeks post-injection throughout the brain. By contrast a pan-silencing control decreased expression 
of both mHTT and wtHTT, and the silencing activity was both less potent and less durable than the allele-selective molecule, especially in the striatum. 

Data are mean ± SD, n=8; Stats: ns non-significant, *P<0.05, **P<0.01, ***P<0.0001, ****P<0.0001 versus PBS by 1-way ANOVA

Amyotrophic Lateral Sclerosis and Frontotemporal Dementia

Hexanucleotide G4C2 expansions found in the C9orf72 gene are one of the most common genetic causes of the sporadic and inherited forms of 
Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD). Some patients exhibit characteristics of both ALS and FTD, indicating that 
these diseases form part of a continuum of neurological disease with some overlap in symptoms between them. 

ALS Background and Market Opportunity 

ALS is a neurodegenerative disease characterized by the progression and degeneration of motor neurons in the brain and spinal cord. Diagnosis may take 
up to 12 months and is made clinically by assessing the signs of upper and lower motor neuron degeneration in the same region of the body. Patients 
initially present with limb-onset disease (approximately 70% of patients), bulbar-onset disease (approximately 25% of patients) or with initial trunk or 
respiratory involvement (approximately 5% of patients). Age of onset is generally in the mid-to-late 50s, and median survival is three years; however, up to 
24% of patients survive for five to ten years. Survival in patients with C9orf72 ALS may be shorter than in patients with sporadic ALS. 

In the United States and Europe combined, there are approximately three to five ALS patients per 100,000 people. This translates to approximately 13,000 
diagnosed patients in the United States, although the total prevalence may be around 20,000 people in the United States. There are one or two newly 
diagnosed cases of ALS per year, per 100,000 people in the United States and Europe combined, resulting in approximately 5,000 newly diagnosed patients 
in the United States each year. While the majority of ALS cases 

33

 
 
 
 
are sporadic, approximately 10% of cases are found to be familial in nature. The C9orf72 gene mutation is currently the most common demonstrated 
mutation related to ALS and is present in approximately 40% of familial ALS and 8 – 10% of sporadic ALS patients. 

ALS Current Treatments

There is significant unmet need for the treatment of ALS. Three medicines are currently approved in the United States for the treatment of ALS. Rilutek 
(riluzole), an inhibitor of glutamate release, was approved in 1995 for the treatment of patients with ALS. It was demonstrated to extend survival by three 
to six months. Radicava (edaravone) was approved in 2017 for the treatment of ALS. Administration of edaravone resulted in a significantly smaller 
decline in the ALS Functional Rating Scale-Revised (“ALSFRS-R”) through six months of treatment as compared to placebo. Relyvrio (sodium 
phenylbutyrate and taurursodiol) was approved in 2022 for the treatment of ALS. In a clinical trial, patients treated with Relyvrio scored on average 2.32 
points higher than placebo on the ALSFRS-R after 6 months. A post-hoc exploratory survival analysis showed that patients originally randomized to 
Relyvrio had a 4.8 month longer median overall survival compared to those in the placebo group.

FTD Background and Market Opportunity

FTD is a neurodegenerative disorder of the frontal and anterior temporal lobes of the brain. It is characterized by changes in personality, cognition (e.g., 
language impairment and executive dysfunction), and behavior (e.g., disinhibition, apathy and compulsivity). Diagnostic criteria categorize FTD into either 
the behavioral variant (approximately 60% of patients) or speech/language variant (approximately 40% of patients) based on the primary symptom 
observed at presentation; however, FTD results in dementia in all patients. The majority of FTD associated with the G4C2 expansion in the C9orf72 gene is 
categorized as the behavioral variant. FTD frequently has an onset in mid-life, and death typically occurs within three to 14 years of onset. FTD is the 
second most common form of early-onset dementia in people under the age of 65, after AD.

In FTD, the C9orf72 gene mutations appear in approximately 38% of familial cases and approximately 6% of sporadic cases. FTD affects approximately 
55,000 people in the United States, of which 10 – 50% are familial cases and 50 – 90% are sporadic cases.

FTD Current Treatments

There are currently no disease-modifying therapies approved for the treatment of FTD. Treatment to date has involved use of medications for symptomatic 
management.

C9-ALS and C9-FTD Pathology

Expansion of the G4C2 repeat alters the normal expression of the C9orf72 gene and causes the production of repeat-containing RNA sense and antisense 
variants. These RNAs accumulate in cellular nuclei in the form of RNA foci and can be translated into dipeptide repeat (“DPR”) proteins. Neuronal 
degeneration associated with the expression of the repeat expansion is hypothesized to arise either from a toxic loss-of-function mechanism due to a 
reduction in C9orf72 protein, a toxic RNA gain-of-function mechanism through the accumulation of RNA foci and/or DPRs accumulating in the brain and 
spinal cord, or both. WVE-004 is designed to affect multiple drivers of toxicity by preserving C9orf72 protein, thereby not exacerbating loss-of-function, 
and reducing the toxic gain-of-function drivers of disease – RNA foci and DPRs.

Our ALS and FTD Program

WVE-004: In ALS and FTD, we are advancing WVE-004, which uses our novel PN chemistry and preferentially targets the transcripts containing the 
hexanucleotide G4C2 expansion in the C9orf72 gene. WVE-004 is designed to minimize the impact on normal C9orf72 protein in patients, thereby 
reducing potential on-target risk. In vitro, WVE-004 potently and selectively reduced V3 transcripts in iPSC-derived motor neurons, which were derived 
from a patient carrying a C9orf72-repeat expansion. In C9 BAC transgenic mice, WVE-004 led to substantial reductions in repeat-containing C9orf72 
transcripts and dipeptide repeat (“DPR”) proteins that are sustained for at least six months, without disrupting total C9orf72 protein expression. 

FOCUS-C9 Phase 1b/2a clinical trial: The FOCUS-C9 trial is a global, multicenter, randomized, double-blind, placebo-controlled Phase 1b/2a clinical trial 
to assess the safety and tolerability of intrathecal doses of WVE-004 for patients with C9-ALS and/or C9-FTD. Additional objectives include measurement 
of poly(GP) proteins in the cerebrospinal fluid (“CSF”), plasma and CSF pharmacokinetics, and exploratory biomarker and clinical endpoints. The 
FOCUS-C9 trial is designed to be adaptive with dose level and dosing frequency being guided by an independent committee. Preclinical models that have 
established pharmacologic activity have informed the starting dose for this trial. 

34

 
In April 2022 (data cut-off: March 24, 2022), we announced a positive update from FOCUS-C9 driven by the observation of potent, durable reductions of 
poly(GP) dipeptide repeat proteins in CSF with low, single doses of WVE-004. Poly(GP) is a key C9-ALS/C9-FTD disease biomarker that, when reduced 
in CSF, indicates WVE-004’s engagement of target in the brain and spinal cord. In the initial data analysis, reductions in poly(GP) were observed across all 
active treatment groups (10 mg, n=2 patients; 30 mg, n=4 patients; 60 mg, n=3 patients), reaching statistical significance versus placebo (n=3 patients) after 
single 30 mg doses, with a 34% reduction in poly(GP) at day 85 (p=0.011). At the time of analysis, none of the patients dosed with 60 mg had reached day 
85. Adverse events (“AEs”) were balanced across treatment groups, including placebo, and were mostly mild to moderate in intensity. Four patients 
(including one on placebo) experienced severe and/or serious adverse events; three were reported by the investigators to be related to ALS or 
administration, and one was reported by the investigator to be related to study drug. CSF NfL elevations were observed in some patients in the 30 mg and 
60 mg single dose cohorts with no meaningful changes in clinical outcome measures, although the dataset and duration were not sufficient to assess clinical 
effects. There were no treatment-associated elevations in CSF white blood cell counts or protein and no other notable laboratory abnormalities were 
observed.

Based on the poly(GP) reduction data, the observation period for single dose cohorts was extended and additional patients were enrolled into the trial to 
further characterize depth of knockdown, durability and longer-term safety profile. We have also initiated multi-dosing cohorts starting at 10 mg monthly 
and moving through 10 mg quarterly, based on potency and durability of pharmacodynamic effects. Additional data are expected in the first half of 2023. 
An open-label extension trial for FOCUS-C9 participants was initiated in the fourth quarter of 2022 and is ongoing.

Preclinical studies

In our Nature Communications paper (Liu, Y et al. Nat Comms. 2021), we report the discovery of a new targeting sequence that is common to all C9orf72 
transcripts but enables preferential knockdown of repeat-containing transcripts in multiple models and C9BAC transgenic mice. Wild-type C9orf72 alleles 
produce three mRNA transcripts: variant 1 (V1), variant (V2), and variant (V3). We apply our platform to generate stereopure oligonucleotides that target a 
sequence at the exon 1b-intron 1 junction, termed Splice Site-1b (“SS1b”), that is common to all C9orf72 transcripts (shown below in “b”, pre-mRNAs 
corresponding to V1-V3 are illustrated; the coral star indicates SS1b). In multiple in vitro model systems, an unoptimized stereopure oligonucleotide yields 
preferential knockdown of exon1a-containing transcripts. The Nature Communications paper describes our work to identify and validate the targeting site 
to achieve variant-selective knockdown of expansion-containing C9orf72 transcripts. The publication highlights the foundational work that led to the 
development of our clinical candidate.

By targeting the V1 and V3 mRNA transcripts that contain the G4C2 expansion and sparing V2 transcripts and healthy C9orf72 protein, WVE-004 has the 
potential to reduce both RNA-based and protein-based toxicity, thereby impacting the disease course and slowing the progression of ALS or FTD. 

In 2022, we published preclinical data in support of WVE-004 in Molecular Therapy Nucleic Acids (doi: 10.1016/j.omtn.2022.04.007). The publication 
highlights work to demonstrate the potency and durability of effect for WVE-004, as well as its pharmacological properties and ability to preserve C9orf72 
protein in C9 BAC transgenic mice. In vitro, WVE-004 potently and selectively reduced V3 transcripts in iPSC-derived motor neurons, which were derived 
from a patient carrying a C9orf72 repeat expansion.

35

 
 
 
 
WVE-004 led to dose-dependent knockdown of V3 transcripts and DPRs in mouse spinal cord tissue. In the transgenic model, mice express the human 
C9orf72 repeat-containing gene from a bacterial artificial chromosome (“BAC”) insertion. We observed qualitatively similar dose-dependent knockdown 
of V3 transcripts and the polyGP DPR protein in mouse cortex tissue.

In C9 BAC transgenic mice, WVE-004 led to substantial reductions in repeat-containing C9orf72 transcripts and dipeptide repeat proteins that are 
sustained for at least six months, without disrupting total protein expression as shown below.

Spinocerebellar ataxia 3 

Background and Market Opportunity

SCA3 is a rare, hereditary (autosomal dominant) progressive neurodegenerative disorder that results in a lack of muscle control and coordination of the 
upper and lower extremities. Signs and symptoms of SCA3 may begin between childhood and late adulthood and vary greatly. Symptoms may include 
progressive clumsiness in the arms and legs, spasticity, difficulty with gait, and impaired speaking, swallowing and eye movements. Symptoms of the 
disease worsen over time, eventually leading to paralysis. Some patients with SCA3 develop dystonia or symptoms similar to those of PD, including 
twitching of the face or tongue, and nerve damage (neuropathy). Life expectancy ranges from the mid-30s in the more severe forms, to a nearly normal life 
expectancy for those with milder forms of the disease. 

37

 
 
 
 
SCA3 is caused by a CAG-repeat expansion in the ATXN3 gene, resulting in an abnormally long polyglutamine stretch in the encoded ataxin-3 protein. 
Mutant ataxin-3 protein is thought to cause widespread neuronal loss in the brain and spinal cord, likely through a toxic gain-of-function mechanism. SCA3 
is the most common dominantly inherited form of ataxia. The prevalence of SCA3 is believed to be one to two cases in 100,000 people with significant 
geographic and ethnic variations.

Current Treatments

There are currently no disease-modifying therapies approved for treatment of SCA3. Treatment to date has involved the use of medications for 
symptomatic management, as well as physical and occupational therapy.

Our Program

In SCA3, we are continuing to advance our program targeting ATXN3.

Our Collaborations 

Our business strategy is to develop and commercialize a broad pipeline of novel oligonucleotide therapies. As part of this strategy, we have entered into, 
and may enter into new partnership and collaboration agreements as a means of advancing our own therapeutic programs, investing in third-party 
technologies to further strengthen PRISM and leveraging external partnerships to extend the reach of PRISM into therapeutic areas where our platform 
demonstrates a competitive advantage. 

GSK

On December 13, 2022, Wave Life Sciences USA, Inc. and Wave Life Sciences UK Limited, two of our direct, wholly-owned subsidiaries entered into a 
Collaboration and License Agreement (the “GSK Collaboration Agreement”) with GlaxoSmithKline Intellectual Property (No. 3) (“GSK”), which became 
effective on January 27, 2023. Pursuant to the GSK Collaboration Agreement, we and GSK have agreed to collaborate on the research, development, and 
commercialization of oligonucleotide therapeutics, including a global exclusive license to WVE-006. The discovery collaboration has an initial four-year 
research term and combines our proprietary discovery and drug development platform, PRISMTM, with GSK’s unique insights from human genetics and its 
global development and commercial capabilities.

Under the terms of the GSK Collaboration Agreement, we received an upfront payment of $170.0 million, which included a cash payment of $120.0 
million and a $50.0 million equity investment. In addition, assuming WVE-006 and GSK’s eight collaboration programs achieve initiation, development, 
launch, and commercialization milestones, we would be eligible to receive up to $3.3 billion in cash milestone payments, which are described in the 
following two paragraphs.

GSK will receive the exclusive global license to WVE-006, our preclinical, first-in-class A-to-I(G) RNA editing candidate for alpha-1 antitrypsin 
deficiency, with development and commercialization responsibilities transferring to GSK after we complete the first-in-patient study. We will be 
responsible for preclinical, regulatory, manufacturing, and clinical activities for WVE-006 through the initial Phase 1/2 study, at our sole cost. Thereafter, 
GSK will be responsible for advancing WVE-006 through pivotal studies, registration, and global commercialization at GSK’s sole cost. For the WVE-006 
program, we would be eligible to receive up to $225.0 million in development and launch milestone payments and up to $300.0 million in 
commercialization milestone payments, as well as double-digit tiered royalties as a percentage of net sales up to the high teens.

The collaboration has three components:

1) A discovery collaboration which enables us to advance up to three programs leveraging targets informed by GSK’s novel insights;

2) A discovery collaboration which enables GSK to advance up to eight programs leveraging PRISM and our oligonucleotide expertise and 

discovery capabilities; and

3) An exclusive global license for GSK to WVE-006, our preclinical program for AATD that uses our proprietary AIMer technology. Wave will 

maintain development responsibilities for WVE-006 through completion of the first clinical study, at which point development and commercial 
responsibilities will transition to GSK.

The collaboration will enable us to continue building a pipeline of transformational oligonucleotide-based therapeutics and unlock new areas of disease 
biology, as well as realize the full value of WVE-006 as a potential best-in-class treatment for AATD that has potential to simultaneously address both liver 
and lung manifestations of the disease.

The GSK Collaboration Agreement includes options to extend the research term for up to three additional years, which would increase the number of 
programs available to both parties. We will lead all preclinical research for GSK and our collaboration programs up to IND-enabling studies. We will lead 
IND-enabling studies, clinical development and commercialization for our collaboration programs. GSK collaboration programs will transfer to GSK for 
IND-enabling studies, clinical development, and commercialization. 

38

 
Assuming GSK advances eight programs under the collaboration that achieve initiation, development, launch and commercial milestones, we would be 
eligible to receive up to $1.2 billion in initiation, development, and launch milestones and up to $1.6 billion in commercialization milestones, as well as 
tiered royalties as a percentage of net sales into the low-teens. Assuming we advance our collaboration programs through the achievement of pre-
determined milestones, GSK would be eligible to receive royalty payments and commercial milestones from us.

Under the GSK Collaboration Agreement, each party grants to the other party certain licenses to the collaboration products resulting from the parties’ 
respective collaboration programs as well as specific intellectual property licenses to enable the other party to perform its obligations and exercise its rights 
under the GSK Collaboration Agreement, including license grants to enable each party to conduct research, development, and commercialization activities 
pursuant to the terms of the GSK Collaboration Agreement. The parties’ exclusivity obligations to each other are limited on a target-by-target basis with 
regard to targets in the collaboration.

The GSK Collaboration Agreement, unless terminated earlier, will continue until the date on which: (i) with respect to a validation target, the date on which 
such validation target is not advanced into a collaboration program; or (ii) with respect to a collaboration target, the royalty term has expired for all 
collaboration products directed to the applicable collaboration target. The GSK Collaboration Agreement contains customary termination provisions, 
including certain termination rights for convenience, breach, and others, including on a target/program basis or of the Collaboration Agreement in its 
entirety.

With respect to the $50.0 million equity investment referred to above, simultaneously with our entry into the GSK Collaboration Agreement, we entered 
into a share purchase agreement with Glaxo Group Limited (“GGL”), an affiliate of GSK, pursuant to which we agreed to sell to GGL 10,683,761 of our 
ordinary shares at a purchase price of $4.68 per share, for an aggregate purchase price of approximately $50.0 million (the “GSK Equity Investment”). The 
GSK Equity Investment closed on January 26, 2023. The shares purchased by GGL are subject to lock-up and standstill restrictions and carry certain 
registration rights, customary for transactions of this kind. 

Takeda

In February 2018, Wave Life Sciences USA, Inc. (“Wave USA”) and Wave Life Sciences UK Limited (“Wave UK”) entered into a collaboration and 
license agreement (the “Takeda Collaboration Agreement”) for a global strategic collaboration (the “Takeda Collaboration”) with Takeda Pharmaceutical 
Company Limited (“Takeda”), pursuant to which Wave USA, Wave UK and Takeda agreed to collaborate on the research, development and 
commercialization of oligonucleotide therapeutics for disorders of the Central Nervous System (“CNS”). The Takeda Collaboration provided us with at 
least $230.0 million in committed cash and Takeda with the option to co-develop and co-commercialize our CNS development programs in (1) 
Huntington’s disease (“HD”); (2) amyotrophic lateral sclerosis (“ALS”) and frontotemporal dementia (“FTD”); and (3) our discovery-stage program 
targeting ATXN3 for the treatment of spinocerebellar ataxia 3 (“SCA3”) (collectively, “Category 1 Programs”), which we will have the right to co-
commercialize in the United States. In addition, the Takeda Collaboration provided Takeda with the right to exclusively license multiple preclinical 
programs for CNS disorders, including Alzheimer’s disease and Parkinson’s disease (collectively, “Category 2 Programs”). In April 2018, the Takeda 
Collaboration became effective and Takeda paid Wave $110.0 million as an upfront payment. Takeda also agreed to fund our research and preclinical 
activities in the amount of $60.0 million during the four-year research term and to reimburse Wave for any collaboration-budgeted research and preclinical 
expenses incurred by us that exceed that amount. 

On October 15, 2021, we and Takeda entered into the Second Amendment (the “Amendment”) to the Takeda Collaboration Agreement, which amended the 
Category 2 component of the two-part collaboration (the “Category 2 Programs”). As discussed above, under Category 2 of the Takeda Collaboration 
Agreement, we had granted Takeda the right to exclusively license multiple preclinical programs for CNS disorders during a four-year research term. 
Pursuant to the terms of the Amendment, we and Takeda discontinued the Category 2 component of the Takeda Collaboration Agreement and Takeda paid 
us an additional $22.5 million for collaboration-related research and preclinical expenses. As a result of the Amendment, we are free to advance our CNS 
programs independently or enter partnerships in the CNS field outside of the three specified targets, C9orf72, HTT and ATXN3, including WVE-004 and 
WVE-003, that are part of the ongoing late-stage Category 1 Programs. The Category 1 component of the original Takeda Collaboration Agreement 
remains in effect and is unchanged by the Amendment.

Simultaneously with Wave USA and Wave UK’s entry into the Takeda Collaboration Agreement, we entered into a share purchase agreement with Takeda 
(the “Takeda Equity Agreement,” and together with the Takeda Collaboration Agreement, the “Takeda Agreements”) pursuant to which we agreed to sell to 
Takeda 1,096,892 of our ordinary shares at a purchase price of $54.70 per share. In April 2018, we closed the Takeda Equity Agreement and received 
aggregate cash proceeds of $60.0 million. The parties also agreed for the shares purchased by Takeda to be subject to certain lock-up and standstill 
restrictions and carry certain registration rights, customary for transactions of this kind.

With respect to Category 1 Programs, we will be responsible for researching and developing products and companion diagnostics for Category 1 Programs 
through completion of the first proof of mechanism study for such products. Takeda will have an exclusive option for each target and all associated 
products and companion diagnostics for such target, which it may exercise at any time through completion of the proof of mechanism study. If Takeda 
exercises this option, we will receive an opt-in payment and will lead manufacturing and joint clinical co-development activities and Takeda will lead joint 
co-commercial activities in the United States and 

39

 
all commercial activities outside of the United States. Global costs and potential profits will be shared 50:50 and we will be eligible to receive development 
and commercial milestone payments. In addition to its 50% profit share, we are eligible to receive option exercise fees and development and commercial 
milestone payments for each of the Category 1 Programs.

Under the Takeda Collaboration Agreement, each party grants to the other party specific intellectual property licenses to enable the other party to perform 
its obligations and exercise its rights under the Takeda Collaboration Agreement, including license grants to enable each party to conduct research, 
development and commercialization activities pursuant to the terms of the Takeda Collaboration Agreement.

The term of the Takeda Collaboration Agreement commenced on April 2, 2018 and, unless terminated earlier, will continue until the date on which: (i) with 
respect to each Category 1 Program target for which Takeda does not exercise its option, the expiration or termination of the development program with 
respect to such target; or (ii) with respect to each Category 1 Program target for which Takeda exercises its option, the date on which neither party is 
researching, developing or manufacturing any products or companion diagnostics directed to such target.

Takeda may terminate the Takeda Collaboration Agreement for convenience on 180 days’ notice, in its entirety or on a target-by-target basis. Subject to 
certain exceptions, each party has the right to terminate the Takeda Collaboration Agreement on a target-by-target basis if the other party, or a third party 
related to such party, challenges the patentability, enforceability or validity of any patents within the licensed technology that cover any product or 
companion diagnostic that is subject to the Takeda Collaboration Agreement. In the event of any material breach of the Takeda Collaboration Agreement by 
a party, subject to cure rights, the other party may terminate the Takeda Collaboration Agreement in its entirety if the breach relates to all targets or on a 
target-by-target basis if the breach relates to a specific target. In the event that Takeda and its affiliates cease development, manufacturing and 
commercialization activities with respect to compounds or products subject to the Takeda Collaboration Agreement and directed to a particular target, we 
may terminate the Takeda Collaboration Agreement with respect to such target. Either party may terminate the Takeda Collaboration Agreement for the 
other party’s insolvency. In certain termination circumstances, we would receive a license from Takeda to continue researching, developing and 
manufacturing certain products, and companion diagnostics.

Asuragen 

In November 2019, we entered into an agreement with Asuragen, Inc. (which was acquired by Bio-Techne Corporation in April 2021) (“Asuragen”), a 
molecular diagnostics company, for the development and potential commercialization of companion diagnostics for our investigational allele-selective 
therapeutic programs targeting HD. This collaboration uses Asuragen’s market-leading repetitive sequence diagnostic expertise to provide scalable SNP 
phasing to support global development programs and future commercialization at a global level. Asuragen has leveraged its AmplideX® PCR technology 
to develop companion diagnostic tests designed to size and phase HTT CAG repeats with the SNPs targeted by our previous investigational therapeutic 
programs in HD, as well as WVE-003, our current HD program being investigated in the ongoing SELECT-HD clinical trial. These tests are designed to aid 
clinicians in selecting HD patients by identifying the SNPs that are in phase with the CAG-expanded allele.

Manufacturing 

To provide internal cGMP manufacturing capabilities and increase control and visibility of our drug product supply chain, we entered into a lease in 
September 2016 for a multi-use facility of approximately 90,000 square feet in Lexington, Massachusetts and initiated the build out of manufacturing space 
and related capabilities. Through our internal manufacturing, we have the capacity to support multiple discovery-, preclinical-, and early clinical-stage 
programs and have the established expertise to efficiently conduct manufacturing runs for oligonucleotides across a spectrum of modalities. In addition to 
manufacturing space, the Lexington facility includes additional laboratory and office space. This facility supplements our existing Cambridge, 
Massachusetts laboratory and office space headquarters, enhances our ability to secure drug substance for current and future development activities and 
may provide commercial-scale manufacturing capabilities. In July 2017, we took occupancy of the Lexington facility and began manufacturing production 
in the fourth quarter of 2017.

We believe that leveraging our internal manufacturing capabilities along with expertise from CMOs facilitates our growth and enhances our ability to 
secure drug substance for current and future research, clinical and early-stage commercial development activities. We believe that the addition of our 
internal cGMP manufacturing capabilities, together with the supply capacity we have established externally, will be sufficient to meet our anticipated 
manufacturing needs for the next several years. We monitor the availability of capacity for the manufacture of drug substance and drug product and believe 
that our supply agreements with our contract manufacturers and the lead times for new supply agreements would allow us to access additional capacity if 
needed. We 

40

 
believe that our product candidates can be manufactured at scale and with production and procurement efficiencies that will result in commercially 
competitive costs. 

Intellectual Property

We believe that we have a strong intellectual property position relating to the development and commercialization of our stereopure oligonucleotides. Our 
intellectual property portfolio includes filings designed to protect stereopure oligonucleotide compositions generally, as well as filings designed to protect 
stereopure compositions of oligonucleotides with particular stereochemical patterns (for example, that affect or confer biological activity). Our portfolio 
also includes filings for both proprietary methods and reagents, as well as various chemical methodologies that enable production of such stereopure 
oligonucleotide compositions. In addition, our portfolio includes filings designed to protect methods of using stereopure oligonucleotide compositions and 
filings designed to protect particular stereopure oligonucleotide products, such as those having a particular sequence, pattern of nucleoside and/or backbone 
modification, pattern of backbone linkages and/or pattern of backbone chiral centers. 

We own or have rights to worldwide patent filings that protect our proprietary technologies for making stereopure oligonucleotide compositions, and that 
also protect the compositions themselves, as well as methods of using them, including in the treatment of diseases. Our portfolio includes multiple issued 
patents, including in major market jurisdictions such as the United States, Europe and Japan. We also have applications pending in multiple jurisdictions 
around the world, including these major market jurisdictions. 

Synthetic Methodologies 

Our patent portfolio includes multiple families that protect synthetic methodologies and/or reagents for generating stereopure oligonucleotide compositions. 
Certain synthetic methodologies and/or reagents are covered by families, which include an issued Japanese patent whose 20-year term extends to 2025. 

Additional synthetic methodologies and/or reagents are protected by other families in our patent portfolio. Certain such families have 20-year expiration 
dates that range from 2029 to at least 2042. Some of these families have issued patents in several jurisdictions, including in major market jurisdictions such 
as the United States, Europe, and/or Japan, have pending applications in multiple jurisdictions including in these major market jurisdictions, or are in the 
international stage. 

We also co-own with the University of Tokyo certain filings that are directed to certain methods and/or reagents for synthesizing oligonucleotides; their 20-
year expiration dates fall in 2031.

Stereopure Oligonucleotide Compositions

Certain of our patent filings protect stereopure compositions, particularly of therapeutically relevant oligonucleotides. Some such filings are directed to 
compositions whose oligonucleotides are characterized by particular patterns of chemical modification (including modifications of bases, sugars and/or 
internucleotidic linkages) and/or of internucleotidic linkage stereochemistry. Certain patent filings describe specific compositions designed for use in the 
treatment of particular diseases. Several of our patent filings directed to stereopure compositions have entered national stage prosecution in multiple 
jurisdictions and some have issued in one or more jurisdictions; others are in the international stage. Certain filings offer 20-year protection terms that 
range from 2033 to at least 2042. 

We also co-own with Shin Nippon Biomedical Laboratories, Ltd. various patent families, some of which include one or more issued patents, including in 
major market jurisdictions; these filings have 20-year terms extending to 2033-2035. 

Future Filings 

We maintain a thoughtful and ambitious program for developing and protecting additional intellectual property, including new synthetic methodologies and 
reagents. We also intend to prepare and submit patent filings specifically directed to protecting individual product candidates and their uses as we finalize 
leads and collect relevant data, which is expected to include comparison data confirming novel and/or beneficial attributes of our product candidates. 

Singapore Intellectual Property Law 

Section 34 of the Patents Act 1994 of Singapore (the “Singapore Patents Act”) provides that a person residing in Singapore is required to obtain written 
authorization from the Singapore Registrar of Patents (the “Registrar”) before filing an application for a patent for an invention outside of Singapore, unless 
all of the following conditions have been satisfied: (a) the person has filed an application for a patent for the same invention in the Singapore Registry of 
Patents at least two months before the filing of the patent application outside Singapore, and (b) the Singapore Registrar of Patents has not, in respect of 
this patent application, given directions to prohibit or restrict the publication of information contained in the patent application or its communication to any 
persons or description of 

41

 
persons pursuant to Section 33 of the Singapore Patents Act, or if the Registrar has given any such directions, all such directions have been revoked. A 
violation of Section 34 is a criminal offense punishable by a fine not exceeding S$5,000, or imprisonment for a term not exceeding two years, or both. 
There have been some instances where we have undertaken filings outside of Singapore, and there may be instances where we are required to make such 
filings in the future, without first obtaining written authorization from the Registrar. We have notified the Registrar of such filings and we have since 
implemented measures to address the requirements of Section 34 moving forward. To date, the Registrar has offered a compound of some of the offences 
considered against payment of a sum of S$50 to S$150 per considered case. Under Singapore law, the Registrar has discretion to offer a compound of such 
offences against payment of a sum of money of up to S$2,000, or to prosecute the offence subject to the other penalties noted above. Per requests in the 
Registrar’s most recent decision, we have submitted approximately 140 patent applications in multiple patent families, most of which are related to 
previously reported applications, to the Intellectual Property Office of Singapore (“IPOS”). The IPOS may consider the filing of some or all of these 
applications to have breached Section 34 requirements per IPOS’ current interpretation of Section 34, and we are waiting for IPOS’ decision on these 
applications. We cannot assure you that the Registrar will offer to compound any such violations of Section 34, or that any offer to compound will be for an 
amount similar to previous compound offers. 

Competition 

The biotechnology and pharmaceutical marketplace is characterized by rapidly advancing technologies, intense competition and a strong emphasis on 
proprietary products. While we believe that our expertise in oligonucleotides, scientific knowledge and intellectual property estate provide us with 
competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and 
biotechnology companies, academic institutions, governmental agencies and public and private research institutions. Not only must we compete with other 
companies that are focused on oligonucleotides, but any product candidates that we successfully develop and commercialize will compete with existing 
therapies and new therapies that may become available in the future. 

Many of our competitors may have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, 
conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. These competitors also compete with us in 
recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well 
as in acquiring technologies complementary to, or necessary for, our programs. Mergers and acquisitions in the pharmaceutical, biotechnology and 
diagnostic industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early stage companies 
may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. 

Duchenne Muscular Dystrophy

There are two treatments approved in the United States for the treatment of DMD in patients who have a confirmed mutation of the DMD gene amenable to 
exon 53 skipping: Sarepta Therapeutics’ Vyondys 53 (golodirsen), an exon skipping nucleic acid therapeutic, was approved by the FDA in 2019, and NS 
Pharma’s Viltepso (viltolarsen), an exon skipping nucleic acid therapeutic, was approved by the FDA in 2020. Both therapies received accelerated 
approval, as the FDA concluded that the data submitted by each company demonstrated an increase in dystrophin production that is reasonably likely to 
predict clinical benefit in some patients with DMD who have a confirmed mutation of the DMD gene amenable to exon 53 skipping. No clinical benefit of 
golodirsen or viltolarsen has been established. Thus, in accordance with the U.S. accelerated approval regulations, the FDA is requiring Sarepta and NS 
Pharma to each conduct a clinical trial to verify and describe their drug’s clinical benefit. Sarepta’s study of golodirsen would need to assess whether 
golodirsen improves motor function of DMD patients with a confirmed mutation of the DMD gene amenable to exon 53 skipping, and NS Pharma’s study 
of viltolarsen is designed to assess whether viltolarsen improves the time to stand for DMD patients amenable to exon 53 skipping. If the trials fail to verify 
clinical benefit, the FDA could initiate proceedings to withdraw approval of the respective drug. 

Several other companies have investigational drugs in clinical development targeting DMD more broadly, including patients amenable to exon 53 skipping. 
These include Capricor Therapeutics (Phase 3), Dystrogen Therapeutics (Phase 1), Edgewise Therapeutics (Phase 2), FibroGen (Phase 3), Pfizer (Phase 3), 
Santhera Pharmaceuticals (pre-registration), and Sarepta Therapeutics (pre-registration), among others. Based on available information, we do not believe 
there are other companies with investigational programs for exon 53 skipping in clinical development. 

Several companies also have ongoing preclinical programs for DMD that may directly or indirectly target patients amenable to exon 53 skipping. These 
companies include Code Bio, Dyne Therapeutics, Daiichi Sankyo, Entrada Therapeutics, PepGen, Precision BioSciences, Sarepta Therapeutics, Solid 
Biosciences, and Ultragenyx, among others.

Alpha-1 Antitrypsin Deficiency (“AATD”)

There are five treatments approved in the United States for AATD: Prolastin, Prolastin-C, Aralast NP, Zemaira, and Glassia. All five contain plasma-
derived human alpha1-proteinase inhibitor and are indicated for chronic augmentation and maintenance therapy in adults with emphysema due to 
congenital deficiency of alpha1-proteinase inhibitor (Alpha1-PI). The prescribing information for each notes that the effect of augmentation therapy with 
any alpha1-proteinase inhibitor on pulmonary exacerbations and on the progression of emphysema in Alpha1-PI deficiency has not been demonstrated in 
randomized, controlled clinical trials.

There are also a number of companies with investigational drugs in clinical development: Arrowhead Pharmaceuticals and Takeda (Phase 3), Dicerna 
Pharmaceuticals and Alnylam Pharmaceuticals (Phase 2), InhibRx (Phase 1), Kamada (Phase 3), Mereo BioPharma (Phase 2), and Vertex Pharmaceuticals 
(Phase 2).

There are also several companies with ongoing discovery or preclinical programs for AATD including Apic Bio, Beam Therapeutics, Biomarin, Epic Bio, 
Intellia Therapeutics, KorroBio, and Krystal Biotech, among others.

Huntington’s Disease 

There are no approved treatments available to slow the progression of HD. We believe, based on publicly available information, that Annexon Biosciences 
(Phase 2), AskBio (Phase 1/2), Ionis Pharmaceuticals and Roche (Phase 2), Mitochon Pharmaceuticals (Phase 2), Prilenia Therapeutics (Phase 3), PTC 
Therapeutics (Phase 2), and uniQure (Phase 1/2), among others, have investigational drugs in clinical development.

Several companies have ongoing discovery or preclinical programs for HD, including Alnylam Pharmaceuticals, Atalanta Therapeutics, LocanaBio, 
Neurimmune, Ophidion, Sangamo Therapeutics and Takeda, Spark Therapeutics, Vico, and Voyager Therapeutics, among others.

A number of companies are developing molecules to treat symptoms associated with HD, including Neurocrine Biosciences (Phase 3), Sage Therapeutics 
(Phase 2), and SOM Biotech (Phase 2), among others. 

Amyotrophic Lateral Sclerosis and Frontotemporal Dementia

There are three treatments approved in the United States for the treatment of ALS: riluzole, approved in 1995, edaravone, approved in 2017, and 
RELYVRIO (sodium phenylbutyrate and taurursodiol), approved in 2022. There are a number of companies with potential therapeutics for the treatment of 
ALS in clinical development, including AB Science (Phase 3), Alector (Phase 2), Biohaven Pharmaceuticals (Phase 2/3), BrainStorm Cell Therapeutics 
(Phase 3 completed), Prilenia (Phase 2/3), and UCB (Phase 2/3), among others. We believe that Transposon Therapeutics has a Phase 2 study targeting 
patients with ALS or FTD due to a C9orf72 mutation.

Several companies have ongoing discovery or preclinical programs for ALS that may directly or indirectly target patients with the C9orf72 mutation, 
including AGTC, Apic Bio, Biogen and Neurimmune, Expansion Therapeutics, Locana Bio, Passage Bio, Pfizer and Sangamo Therapeutics, and uniQure. 

There are no approved treatments available to slow the progression of FTD. Multiple companies have investigational therapies in clinical development for 
the broad FTD population, including Anavex (Phase 1 completed), Denali (Phase 1), and TauRx Pharmaceuticals (Phase 3 complete). Alector and 
Transposon Therapeutics each have ongoing Phase 2 studies targeting patients with FTD due to a C9orf72 mutation.

There are several companies with ongoing discovery or preclinical programs for FTD that may directly or indirectly target patients with the C9orf72 
mutation, including Biogen and Neurimmune, Expansion Therapeutics, and Pfizer and Sangamo Therapeutics.

ADAR-mediated RNA Editing (“ADAR editing”)

There are several companies pursuing editing approaches that may compete with our ADAR editing modality. These companies are in various stages of 
development (discovery through the clinic) and are developing investigational drugs via viral (Shape Therapeutics) and non-viral delivery for RNA editing 
(ProQR and Korro Bio), DNA base-editing (Beam), and DNA editing (Editas Medicine, Intellia Therapeutics, and Sangamo Therapeutics), among others. 
These companies may leverage these approaches to target the same indications that we intend to target or indications where we do not currently plan to 
compete.

Government Regulation

FDA Approval Process for Drug Products

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal Food, Drug and Cosmetic Act (“FDCA”), and 
other federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, recordkeeping, 
approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling, and import and export of pharmaceutical 
products. Failure to comply with applicable FDA or other requirements may subject a pharmaceutical company to a variety of administrative or judicial 
sanctions, such as the FDA’s refusal to approve pending applications, a clinical hold, warning letters, recall or seizure of drug products, partial or total 
suspension of production, withdrawal of drug products from the market, injunctions, fines, civil penalties or criminal prosecution. 

FDA approval is required before any new drug, such as a new molecular or chemical entity, or a new dosage form, new use or new route of administration 
of a previously approved product, can be marketed in the United States. The process required by the FDA before a new drug product may be marketed in 
the United States generally involves: 

•

•

•

•

•

•

•

•

•

•

•

completion of preclinical testing in compliance with applicable FDA good laboratory practice regulations and other requirements (“GLP”); 

submission to the FDA of an Investigational New Drug application (“IND”) for human clinical testing which must become effective before 
human clinical trials may begin in the United States; 

approval by an independent institutional review board (“IRB”) at each site where a clinical trial will be performed before the trial may be 
initiated at that site; 

performance of adequate and well-controlled human clinical trials in accordance with good clinical practice (“GCP”) to establish safety and 
substantial evidence of effectiveness of the proposed product candidate for each intended use; 

thorough characterization of the product candidate and establishment of acceptable standards to ensure suitable purity, identity, strength, 
quality and stability in compliance with cGMP; 

satisfactory completion of an FDA pre-approval inspection of the facility or facilities at which the product is manufactured to assess 
compliance with cGMP; 

satisfactory completion of an FDA pre-approval inspection of one or more clinical trial site(s) or the sponsor’s site and/or contract research 
organization responsible for conduct of key clinical trials in accordance with GCP; 

submission to the FDA of a New Drug Application (“NDA”), which must be accepted for filing by the FDA; 

completion of an FDA advisory committee review, if applicable; 

payment of user fees, if applicable; and 

FDA review and approval of the NDA. 

The manufacturing development, preclinical and clinical testing, and review process requires substantial time, effort and financial resources. Manufacturing 
development includes laboratory evaluation of product chemistry, formulation, development of manufacturing and control procedures, evaluation of 
stability, and the establishment of procedures to ensure continued product quality.

Nonclinical tests may include in vitro and in vivo (animal model) studies to assess the toxicity and other safety characteristics of the product candidate, as 
well as important aspects of drug pharmacology and pharmacodynamics. The Consolidated Appropriations Act for 2023, signed into law on December 29, 
2022, (P.L. 117-328) amended the FDCA and the Public Health Service Act to specify that nonclinical testing for drugs and biologics may, but is not 
required to, include in vivo animal testing. According to the amended language, a sponsor may fulfill nonclinical testing requirements by completing 
various in vitro assays (e.g., cell-based assays, organ chips, or microphysiological systems), in silico studies (i.e., computer modeling), other human or 
nonhuman biology-based tests (e.g., bioprinting), or in vivo animal tests. 

The results of nonclinical tests, together with manufacturing information, analytical data and a proposed clinical trial protocol and other information, are 
submitted as part of an IND to the FDA. Some long-term nonclinical testing to further establish the safety profile of the product candidate, as well as 
manufacturing processes development and drug quality evaluation, continues after the IND is submitted. An IND automatically becomes effective 30 days 
after receipt by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions related to the proposed clinical trial and places the 
IND on a clinical hold. In such a case, the IND sponsor must resolve all outstanding concerns before the clinical trial can begin. As a result, our submission 
of an IND may not result in FDA authorization to commence a clinical trial. A separate submission to an existing IND must also be made for each 
successive 

44

 
clinical trial conducted during product development, or if changes are made in trial design. Even if the IND becomes effective and the trial proceeds 
without initial FDA objection, the FDA may stop the trial at a later time if it has concerns, such as if unacceptable safety risks arise. 

Further, an IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and informed consent 
information for subjects before the trial commences at that site and it must perform an ongoing review of the research on an annual basis until the trial is 
completed. The FDA or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being 
exposed to an unacceptable health risk or that the trials are not being conducted in accordance with the clinical plan or in compliance with GCP. Similarly, 
an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s 
requirements or if the drug has been associated with unexpected serious harm to patients. 

Clinical trials involve the administration of the product candidate to human subjects under the supervision of qualified investigators in accordance with 
GCP requirements, which include the requirement that all research subjects provide their informed consent in writing for their participation in any clinical 
trial. Sponsors of clinical trials of certain FDA-regulated products generally must register and disclose certain clinical trial information to a public registry 
maintained by the National Institutes of Health (“NIH”). In particular, information related to the product, patient population, phase of investigation, study 
sites and investigators and other aspects of the clinical trial is made public as part of the registration of the clinical trial. Competitors may use this publicly 
available information to gain knowledge regarding the progress of development programs. Although sponsors are also obligated to disclose the results of 
their clinical trials after completion, disclosure of the results can be delayed in some cases for up to two years after the date of completion of the trial. 
Failure to timely register a covered clinical study or to submit study results as provided for in the law can give rise to civil monetary penalties and also 
prevent the non-compliant party from receiving future grant funds from the federal government. The NIH’s Final Rule on ClinicalTrials.gov registration 
and reporting requirements became effective in 2017, and the government has brought enforcement actions against non-compliant clinical trial sponsors.

Human clinical trials are typically conducted in the following sequential phases, which may overlap or be combined: 

•

•

•

•

Phase 1. The product is initially introduced into healthy human subjects or patients and tested for safety, dose tolerance, absorption, 
metabolism, distribution and excretion and, if possible, to gain an early indication of its effectiveness. 

Phase 2. The product is administered to a limited patient population to identify possible adverse effects and safety risks, to preliminarily 
evaluate the efficacy of the product for specific targeted indications and to determine dose tolerance and optimal dosage. Multiple Phase 
2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more extensive clinical trials. 

Phase 3. These are commonly referred to as pivotal studies. When Phase 2 evaluations demonstrate that a dose range of the product 
appears to be effective and has an acceptable safety profile, trials are undertaken in larger patient populations to further evaluate dosage, 
to obtain substantial, statistical evidence of clinical efficacy and safety, generally at multiple, geographically-dispersed clinical trial 
sites, to establish the overall risk-benefit relationship of the product and to provide adequate information for approval of the product. 

Phase 4. In some cases, the FDA may condition approval of an NDA for a product candidate on the sponsor’s agreement to conduct 
additional clinical trials to further assess the product’s safety and effectiveness after NDA approval. Such post-approval trials are 
typically referred to as Phase 4 studies. 

Progress reports detailing progress and safety data gathered from clinical trials must be submitted at least annually to the FDA. Safety reports are submitted 
more frequently if certain serious adverse effects (“SAEs”) occur. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any 
specified period, or at all. The FDA will typically inspect one or more clinical sites to assure compliance with GCP and the integrity of the clinical data 
submitted as part of NDA review. Information related to the product, patient population, phase of investigation, study sites and investigators and other 
aspects of the clinical trial is made public as part of the registration of the clinical trial. Sponsors are also obligated to disclose the results of most clinical 
trials after completion, although in some cases disclosure of the results of these trials can be delayed for up to two years after the trial completion date. 
Competitors may use this publicly available information to gain knowledge regarding the progress of development programs.

In the Consolidated Appropriations Act for 2023, Congress amended the FDCA to require sponsors of a Phase 3 clinical trial, or other “pivotal study” of a 
new drug to support marketing authorization, to submit a diversity action plan for such clinical trial. The action plan must include the sponsor’s diversity 
goals for enrollment, as well as a rationale for the goals and a description of how the sponsor will meet them. A sponsor must submit a diversity action plan 
to FDA by the time the sponsor submits the trial protocol to the agency for review. The FDA may grant a waiver for some or all of the requirements for a 
diversity action plan. It is unknown at this time how the diversity action plan may affect Phase 3 trial planning and timing or what specific information 
FDA will expect in such plans, but 

45

 
if FDA objects to a sponsor’s diversity action plan and requires the sponsor to amend the plan or take other actions, it may delay trial initiation.

Assuming successful completion of the required clinical testing, the results of the preclinical studies and clinical trials, along with information relating to 
the product’s pharmacology, chemistry, manufacturing, and controls, and proposed labeling, are submitted to the FDA as part of an NDA requesting 
approval to market the product for one or more indications. Data may come from company-sponsored clinical trials intended to test the safety and efficacy 
of a product’s use or from a number of alternative sources, including studies initiated by investigators. To support marketing approval, the data submitted 
must be sufficient in quality and quantity to establish the safety and efficacy of the investigational product to the satisfaction of the FDA. Under federal 
law, the fee for the submission of an NDA with clinical data is substantial (for example, for fiscal year 2023 this application fee exceeds $3.2 million), and 
the sponsor of an approved NDA is also subject to an annual program fee, currently more than $390,000 per program. These fees are typically adjusted 
annually, but exemptions and waivers may be available under certain circumstances, including NDA fees for products with orphan designation.

The FDA has 60 days from its receipt of an NDA to determine whether the application will be accepted for filing based on the agency’s threshold 
determination that it is sufficiently complete to permit substantive review. The FDA may request additional information rather than accept an NDA for 
filing. Any resubmitted application, following a refusal to file action, is also subject to 60-day review before the FDA accepts it for filing. 

Under the Prescription Drug User Fee Act (“PDUFA”), for original NDAs, the FDA has ten months from the filing date in which to complete its initial 
review of a standard application and respond to the applicant, and six months from the filing date for an application with priority review. For all new 
molecular entity (“NME”) NDAs, the ten and six-month time periods run from the filing date; for all other original applications, the ten and six-month time 
periods run from the submission date. Despite these review goals, it is not uncommon for FDA review of an NDA to extend beyond the goal date. 

Once the submission has been accepted for filing, the FDA begins an in-depth review. As noted above, the FDA has agreed to specified performance goals 
in the review process of NDAs. Most such applications are meant to be reviewed within ten months from the date it is accepted for filing (i.e., 12 months), 
and most applications for “priority review” products are meant to be reviewed within six months from the date the application is accepted for filing (i.e., 
eight months). The review process may be extended by the FDA for three additional months to consider new information or in the case of a clarification 
provided by the applicant to address an outstanding deficiency identified by the FDA following the original submission.

Before approving an NDA, the FDA may inspect the facility or facilities where the product is manufactured. The FDA will not approve an application 
unless it determines that the manufacturing processes and facilities are in compliance with cGMP. The FDA may also inspect one or more of the clinical 
sites where pivotal trials were conducted and the contract research organization facilities with oversight of the trial, in order to ensure compliance with 
GCP and the integrity of the study data.

Additionally, the FDA may refer any NDA, including applications for novel biologic candidates which present difficult questions of safety or efficacy, to an 
advisory committee. Typically, an advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, 
evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the 
recommendation of an advisory committee, but it considers such recommendations when making final decisions on approval. The FDA likely will re-
analyze the clinical trial data, which could result in extensive discussions between the FDA and the applicant during the review process. The FDA also may 
require submission of a risk evaluation and mitigation strategy (“REMS”) if it determines that a REMS is necessary to ensure that the benefits of the drug 
outweigh its risks and to assure the safe use of the drug or biological product. The REMS could include medication guides, physician communication plans, 
assessment plans and/or elements to assure safe use, such as restricted distribution methods, patient registries or other risk minimization tools. In addition, 
the REMS must include a timetable to assess the strategy, often at 18 months, three years, and seven years after the strategy’s approval. The FDA 
determines the requirement for a REMS, as well as the specific REMS provisions, on a case-by-case basis. If the FDA concludes a REMS is needed, the 
sponsor of the NDA must submit a proposed REMS. The FDA will not approve an NDA without a REMS, if required.

In determining whether a REMS is necessary, the FDA may consider the size of the population likely to use the drug, the seriousness of the disease or 
condition to be treated, the expected benefit of the drug, the duration of treatment, the seriousness of known or potential adverse events, and whether the 
drug is an NME. If the FDA determines a REMS is necessary, the drug sponsor must agree to the REMS plan at the time of approval, or at a later date 
should significant new risk information come to light. The FDA may impose a REMS requirement on a drug already on the market if the FDA determines, 
based on new safety information, that a REMS is necessary to ensure that the drug’s benefits outweigh its risks. 

Under the Pediatric Research Equity Act (“PREA”), as amended, an NDA or supplement to an NDA must contain data that are adequate to assess the 
safety and efficacy of the product candidate for the claimed indications in all relevant pediatric populations and to support dosing and administration for 
each pediatric population for which the product is safe and effective. The FDA may grant deferrals for submission of pediatric data or full or partial 
waivers. PREA requires a sponsor who is planning to submit a marketing application for a product that includes a new active ingredient, new indication, 
new dosage form, new dosing regimen or new route of administration to submit an initial Pediatric Study Plan (“PSP”) within 60 days of an end-of-Phase 2 
meeting or, if there is no such 

46

 
meeting, as early as practicable before the initiation of the Phase 3 or Phase 2/3 clinical trial. The initial PSP must include an outline of the pediatric study 
or studies that the sponsor plans to conduct, including trial objectives and design, age groups, relevant endpoints and statistical approach, or a justification 
for not including such detailed information, and any request for a deferral of pediatric assessments or a full or partial waiver of the requirement to provide 
data from pediatric studies along with supporting information. The FDA and the sponsor must reach an agreement on the PSP. A sponsor can submit 
amendments to an agreed upon initial PSP at any time if changes to the pediatric plan need to be considered based on data collected from pre-clinical 
studies, early phase clinical trials or other clinical development programs. 

The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is 
cGMP-compliant to assure and preserve the product’s identity, strength, quality and purity. The approval process is lengthy and often difficult, and the FDA 
may refuse to approve an NDA if the applicable regulatory criteria are not satisfied or may require additional clinical or other data and information. On the 
basis of the FDA’s evaluation of the NDA and accompanying information, including the results of the inspection of the manufacturing facilities, it may 
issue an approval letter or a Complete Response Letter (“CRL”). An approval letter authorizes commercial marketing of the product with specific 
prescribing information for specific indications. A CRL indicates that the review cycle for an application is complete and that the application will not be 
approved in its present form. CRLs outline the deficiencies in the submission and may require substantial additional testing or information in order for the 
FDA to reconsider the application. The CRL may require additional clinical or other data, additional pivotal Phase 3 clinical trial(s) and/or other significant 
and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. If a CRL is issued, the applicant may choose to either 
resubmit the NDA addressing all of the deficiencies identified in the letter or withdraw the application. The FDA has committed to reviewing such 
resubmissions in response to an issued CRL in either two or six months depending on the type of information included. Even with submission of this 
additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. If and when the deficiencies 
have been addressed to the FDA’s satisfaction, the FDA will typically issue an approval letter. 

The FDA may withdraw product approval if ongoing regulatory requirements are not met or if safety problems are identified after the product reaches the 
market. In addition, the FDA may require post-approval testing, including Phase 4 studies, and surveillance programs to monitor the effect of approved 
products which have been commercialized, and the FDA has the authority to prevent or limit further marketing of a product based on the results of these 
post-marketing programs. Products may be marketed only for the approved indications and in accordance with the provisions of the approved label and, 
even if the FDA approves a product, the FDA may limit the approved indications for use for the product or impose other conditions, including labeling or 
distribution restrictions or other risk-management mechanisms, such as a Boxed Warning, which highlights a serious safety concern that should be 
mitigated under a REMS program. Further, if there are any modifications to the product, including changes in indications, labeling, or manufacturing 
processes or facilities, a company is generally required to submit and obtain FDA approval of a supplemental NDA, which may require the company to 
develop additional data or conduct additional nonclinical studies and clinical trials. 

Fast Track, Breakthrough Therapy and Priority Review Designations

The FDA is authorized to designate certain products for expedited development or review if they are intended to address an unmet medical need in the 
treatment of a serious or life-threatening disease or condition. These programs include fast track designation, breakthrough therapy designation and priority 
review designation.

To be eligible for a fast track designation, the FDA must determine, based on the request of a sponsor, that a product is intended to treat a serious or life-
threatening disease or condition and demonstrates the potential to address an unmet medical need by providing a therapy where none exists or a therapy 
that may be potentially superior to existing therapy based on efficacy or safety factors. Fast track designation provides opportunities for more frequent 
interactions with the FDA review team to expedite development and review of the product. The FDA may also review sections of the NDA for a fast track 
product on a rolling basis before the complete application is submitted, if the sponsor and the FDA agree on a schedule for the submission of the 
application sections and the sponsor pays any required user fees upon submission of the first section of the NDA. In addition, fast track designation may be 
withdrawn by the sponsor or rescinded by the FDA if the designation is no longer supported by data emerging from the clinical trial process.

In addition, in 2012 Congress created a regulatory program for product candidates designated by FDA as “breakthrough therapies” upon a request made by 
the IND sponsors. A breakthrough therapy is defined as a drug or biologic that is intended, alone or in combination with one or more other drugs or 
biologics, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug or biologic may demonstrate 
substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in 
clinical development. Drugs or biologics designated as breakthrough therapies are also eligible for accelerated approval of their respective marketing 
applications. The FDA must take certain actions with respect to breakthrough therapies, such as holding timely meetings with and providing advice to the 
product sponsor, which are intended to expedite the development and review of an application for approval of a breakthrough therapy.

Finally, the FDA may designate a product for priority review if it is a drug or biologic that treats a serious condition and, if approved, would provide a 
significant improvement in safety or effectiveness over existing therapy. The FDA determines at the time that the 

47

 
marketing application is submitted, on a case- by-case basis, whether the proposed drug represents a significant improvement in treatment, prevention or 
diagnosis of disease when compared with other available therapies. Significant improvement may be illustrated by evidence of increased effectiveness in 
the treatment of a condition, elimination or substantial reduction of a treatment-limiting drug reaction, documented enhancement of patient compliance that 
may lead to improvement in serious outcomes, or evidence of safety and effectiveness in a new subpopulation. A priority review designation is intended to 
direct overall attention and resources to the evaluation of such applications, and to shorten the FDA’s goal for taking action on a marketing application from 
ten months to six months for an NME NDA from the date of filing.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or 
decide that the time period for FDA review or approval will not be shortened. Furthermore, fast track designation, breakthrough therapy designation and 
priority review do not change the standards for approval and may not ultimately expedite the development or approval process. 

Accelerated Approval Pathway

In addition, products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic 
benefit over existing treatments may receive accelerated approval from the FDA and may be approved on the basis of adequate and well-controlled clinical 
trials establishing that the drug product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit. The FDA may also grant 
accelerated approval for such a drug or biologic when the product has an effect on an intermediate clinical endpoint that can be measured earlier than an 
effect on irreversible morbidity or mortality (“IMM”) and that is reasonably likely to predict an effect on IMM or other clinical benefit, taking into account 
the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA will require that 
a sponsor of a drug receiving accelerated approval perform post-marketing clinical trials to verify and describe the predicted effect on IMM or other 
clinical endpoint, and the product may be subject to expedited withdrawal procedures. Drugs and biologics granted accelerated approval must meet the 
same statutory standards for safety and effectiveness as those granted traditional approval.

For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign, or other 
measure that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. Surrogate endpoints can often be measured more easily or 
more rapidly than clinical endpoints. An intermediate clinical endpoint is a measurement of a therapeutic effect that is considered reasonably likely to 
predict the clinical benefit of a drug, such as an effect on IMM. The FDA has limited experience with accelerated approvals based on intermediate clinical 
endpoints, but has indicated that such endpoints generally may support accelerated approval when the therapeutic effect measured by the endpoint is not 
itself a clinical benefit and basis for traditional approval, if there is a basis for concluding that the therapeutic effect is reasonably likely to predict the 
ultimate long-term clinical benefit of a drug.

The accelerated approval pathway is most often used in settings in which the course of a disease is long and an extended period of time is required to 
measure the intended clinical benefit of a drug, even if the effect on the surrogate or intermediate clinical endpoint occurs rapidly. For example, accelerated 
approval has been used extensively in the development and approval of drugs for treatment of a variety of cancers in which the goal of therapy is generally 
to improve survival or decrease morbidity and the duration of the typical disease course requires lengthy and sometimes large clinical trials to demonstrate 
a clinical or survival benefit.

The accelerated approval pathway is usually contingent on a sponsor’s agreement to conduct, in a diligent manner, additional post-approval confirmatory 
studies to verify and describe the drug’s clinical benefit. As a result, a product candidate approved on this basis is subject to rigorous post-marketing 
compliance requirements, including the completion of Phase 4 or post-approval clinical trials to establish the effect on the clinical endpoint. Failure to 
conduct required post-approval studies, or to confirm the predicted clinical benefit of the product during post-marketing studies, would allow the FDA to 
withdraw approval of the drug. As part of the Consolidated Appropriations Act for 2023, Congress provided FDA additional statutory authority to mitigate 
potential risks to patients from continued marketing of ineffective drugs previously granted accelerated approval. Under the act’s amendments to the 
FDCA, FDA may require the sponsor of a product granted accelerated approval to have a confirmatory trial underway prior to approval. The sponsor must 
also submit progress reports on a confirmatory trial every six months until the trial is complete, and such reports are published on FDA’s website. The 
amendments also give FDA the option of using expedited procedures to withdraw product approval if the sponsor’s confirmatory trial fails to verify the 
claimed clinical benefits of the product.

All promotional materials for product candidates being considered and approved under the accelerated approval program are subject to prior review by the 
FDA.

Post-Approval Requirements 

Once an NDA is approved, a product will be subject to continuing regulation by the FDA, including, among other things, requirements relating to safety 
surveillance and adverse event reporting, periodic reporting, continued cGMP compliance and quality oversight, 

48

 
compliance with post-marketing commitments, recordkeeping, advertising and promotion, and reporting manufacturing and labeling changes, as applicable.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs (including third-party manufacturers) are 
required to register their establishments with the FDA and some state agencies and are subject to periodic unannounced inspections by the FDA and some 
state agencies for assessment of compliance with cGMP. Changes to the manufacturing process are strictly regulated and often require prior FDA approval 
before being implemented. FDA regulations also require investigation and correction, and sometimes notification of, any deviations from cGMP. These 
regulations impose reporting and documentation requirements on the sponsor and any third-party manufacturers that we may decide to use. Accordingly, 
manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. 

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if 
problems occur after the product reaches the market. Discovery of previously unknown problems with a product, including adverse events of unlisted 
severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements such as noncompliance with cGMP or failure to 
correct previously identified inspection findings, may result in mandatory revisions to the approved labeling to add new safety information; imposition of 
post-market or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential 
consequences include, among other things: 

•

•

•

•

•

•

•

issuance of field alerts, restrictions on the marketing or manufacturing of the product, product recalls, or complete withdrawal of the 
product from the market; 

mandated modification of promotional materials and labeling and the issuance of corrective information; 

fines, warning letters or other enforcement-related letters or holds on clinical trials using the product or other products manufactured 
at the same facility; 

refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of product 
approvals; 

product seizure or detention, or refusal to permit the import or export of products; 

injunctions or the imposition of civil or criminal penalties; and

consent decrees, corporate integrity agreements, debarment, or exclusion from federal health care programs. 

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. While physicians may generally 
prescribe a drug for off-label uses, manufacturers may only promote the drug in accordance with the approved product label. The FDA and other agencies 
actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have promoted false and misleading 
information about the product may be subject to significant liability, both at the federal and state levels. 

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act (“PDMA”) which regulates the 
distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors by the states. 
Both the PDMA and state laws limit the distribution of prescription drug product samples and impose requirements to ensure accountability in distribution. 
Most recently, the Drug Supply Chain Security Act (“DSCSA”) was enacted with the aim of building an electronic system to identify and trace certain 
prescription drugs distributed in the United States. The DSCSA mandates phased-in and resource-intensive obligations for pharmaceutical manufacturers, 
wholesale distributors, and dispensers over a ten‑year period that is expected to culminate in November 2023. From time to time, new legislation and 
regulations may be implemented that could significantly change the statutory provisions governing the approval, manufacturing and marketing of products 
regulated by the FDA. It is impossible to predict whether further legislative or regulatory changes will be enacted, or FDA regulations, guidance or 
interpretations changed or what the impact of such changes, if any, may be.

Orphan Drug Designation 

Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is defined as one 
affecting fewer than 200,000 individuals in the United States or more than 200,000 individuals where there is no reasonable expectation that the product 
development cost will be recovered from product sales in the United States. Orphan drug designation must be requested before submitting an NDA. After 
the FDA grants orphan drug designation, the identity of the drug and its potential orphan use will be disclosed publicly by the FDA; the posting will also 
indicate whether a drug is no longer designated as an orphan drug. More than one product candidate may receive an orphan drug designation for the same 
indication. Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process. 

49

 
 
Under PREA, submission of a pediatric assessment is not required for pediatric investigation of a product that has been granted orphan drug designation. 
However, under the FDA Reauthorization Act of 2017 (“FDASIA”), the scope of the PREA was extended to require pediatric studies for products intended 
for the treatment of an adult cancer that are directed at a molecular target that are determined to be substantially relevant to the growth or progression of a 
pediatric cancer. In addition, the FDA finalized guidance in 2018 indicating that it does not expect to grant any additional orphan drug designation to 
products for pediatric subpopulations of common diseases. Nevertheless, the FDA intends to still grant orphan drug designation to a drug or biologic that 
otherwise meets all other criteria for designation when it prevents, diagnoses or treats either (i) a rare disease that includes a rare pediatric subpopulation, 
(ii) a pediatric subpopulation that constitutes a valid orphan subset, or (iii) a rare disease that is in fact a different disease in the pediatric population as 
compared to the adult population.

If an orphan drug-designated product subsequently receives FDA approval for the disease for which it was designed, the product will be entitled to seven 
years of product exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication, except in 
very limited circumstances (such as a showing of clinical superiority to the product with orphan exclusivity by means of greater effectiveness, greater 
safety or providing a major contribution to patient care or in instances of drug supply issues), for seven years. Orphan exclusivity does not block the 
approval of a different drug or biologic for the same rare disease or condition, nor does it block the approval of the same drug or biologic for different 
conditions. If a competitor obtains approval of the same drug, as defined by the FDA, or if our product candidate is determined to be the same drug as a 
competitor’s product for the same indication or disease, the competitor’s exclusivity could block the approval of our product candidate in the designated 
orphan indication for seven years, unless our product is demonstrated to be clinically superior to the competitor’s drug. 

European Union Orphan Drug Designation 

In the European Union (the “EU”), orphan drug designation by the European Commission (the “EC”) provides regulatory and financial incentives for 
companies to develop and market therapies that meet the following requirements: (1) the product is intended for the diagnosis, prevention or treatment of 
life-threatening or chronically debilitating conditions; (2) either (a) such condition affects no more than five in 10,000 persons in the European Union when 
the application is made, or (b) the product, without the benefits derived from orphan status, would not generate sufficient return in the European Union to 
justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the 
European Union, or if such a method exists, the product will be of significant benefit to those affected by the condition, as defined in Regulation (EC) 
847/2000. To be considered for orphan drug designation in the EU, companies must provide data that demonstrate the plausibility for use of the 
investigational therapy in the treatment of the disease and establish that the drug has the potential to provide relevant advantages or a major contribution to 
patient care over existing therapies.

Among the incentives available to medicines designated as orphan drugs by the EC are ten-year market exclusivity in the EU after product approval, 
eligibility for conditional marketing authorization, protocol assistance from the European Medicines Agency at reduced fees during the product 
development phase and direct access to centralized marketing authorization in the EU. The exclusivity period may be reduced to six years if, at the end of 
the fifth year, the orphan drug designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify 
maintenance of market exclusivity. In addition, marketing authorization may be granted to a similar medicinal product with the same orphan indication 
during the ten-year period with the consent of the marketing authorization holder for the original orphan medicinal product or if the manufacturer of the 
original orphan medicinal product is unable to supply sufficient quantities of the product. Marketing authorization may also be granted to a similar 
medicinal product with the same orphan indication if the similar product is deemed safer, more effective or otherwise clinically superior to the original 
orphan medicinal product. Orphan drug designation must be requested before submitting an application for marketing authorization. Orphan drug 
designation does not, in itself, convey any advantage in, or shorten the duration of, the regulatory review and authorization process.

Pediatric Exclusivity and Pediatric Use

The Best Pharmaceuticals for Children Act (“BPCA”) provides NDA holders a six-month period of non-patent marketing exclusivity attached to any other 
exclusivity listed with FDA—patent or non-patent—for a drug if certain conditions are met. Conditions for pediatric exclusivity include a determination by 
the FDA that information relating to the use of a new drug in the pediatric population may produce health benefits in that population; a written request by 
the FDA for pediatric studies; and agreement by the applicant to perform the requested studies and the submission to the FDA, completion of the studies in 
accordance with the written request, and the acceptance by the FDA, of the reports of the requested studies within the statutory timeframe. The data do not 
need to show the product to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the 
additional protection is granted. If reports of requested pediatric studies are submitted to and accepted by the FDA within the statutory time limits, 
whatever statutory or regulatory periods of exclusivity or patent protection cover the product are extended by six months. This is not a patent term 
extension, but it effectively extends the regulatory period during which the FDA cannot approve another application. The issuance of a written request does 
not require the sponsor to undertake the described studies. Applications under the BPCA are treated as priority applications.

The Hatch-Waxman Act and Marketing Exclusivity

In 1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress authorized the FDA to approve generic drugs that are the same as drugs 
previously approved by the FDA under the NDA provisions of the statute and also enacted Section 505(b)(2) of the FDCA. To obtain approval of a generic 
drug, an applicant must submit an abbreviated new drug application (“ANDA”) to the agency. In support of such applications, a generic manufacturer may 
rely on the preclinical and clinical testing conducted for a drug product previously approved under an NDA, known as the reference listed drug (“RLD”). 
Specifically, in order for an ANDA to be approved, the FDA must find that the generic version is identical to the RLD with respect to the active 
ingredients, the route of administration, the dosage form, and the strength of the drug. At the same time, the FDA must also determine that the generic drug 
is “bioequivalent” to the innovator drug.

Upon NDA approval of a new chemical entity (“NCE”), which is a drug that contains no active moiety that has been approved by the FDA in any other 
NDA, that drug receives five years of marketing exclusivity. During the exclusivity period, the FDA cannot accept for review any ANDA or 505(b)(2) 
NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data 
required for approval. However, an application may be submitted one year before NCE exclusivity expires if a Paragraph IV certification is filed on an 
NCE patent and any time after approval if the application is filed based on a new indication or a new formulation.

The Hatch-Waxman Act also provides three years of data exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new clinical 
investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval 
of the application, for example, new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the conditions of use 
associated with the new clinical investigations and does not prohibit the FDA from approving follow-on applications for drugs containing the original 
active agent. If there is no listed patent in the Orange Book, there may not be a Paragraph IV certification, and, thus, no ANDA or 505(b)(2) NDA may be 
filed before the expiration of the exclusivity period. Five-year and three-year exclusivity also will not delay the submission or approval of a traditional 
NDA filed under Section 505(b)(1) of the FDCA. However, an applicant submitting a traditional NDA would be required to either conduct or obtain a right 
of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Patent Term Restoration 

Depending upon the timing, duration and specifics of FDA approval of the use of our therapeutic candidates, some of our U.S. patents may be eligible for 
limited patent term extension under the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation 
for any patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining 
term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the 
effective date of an IND and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application. 
Only one patent applicable to an approved drug is eligible for the extension and the application for extension must be made prior to the expiration of the 
patent. The United States Patent and Trademark Office (“USPTO”), in consultation with the FDA, reviews and approves the application for any patent term 
extension or restoration. In the future, we intend to apply for restorations of patent term for some of our currently owned or licensed patents to add patent 
life beyond their current expiration date, depending on the expected length of clinical trials and other factors involved in the submission of the relevant 
NDA. 

In Vitro Diagnostic Tests for Biomarkers

For some of our product candidates, we plan to work with collaborators to develop or obtain access to in vitro companion diagnostic tests to identify 
appropriate patients for these targeted therapies. If a sponsor or the FDA believes that a diagnostic test is essential for the safe and effective use of a 
corresponding therapeutic product, a sponsor will typically work with a collaborator to develop an in vitro diagnostic (“IVD”). IVDs are regulated by the 
FDA as medical devices, and since 2014 the agency has issued final and draft guidance documents that are intended to assist companies developing in vitro 
companion diagnostic devices and companies developing therapeutic products that depend on the use of a specific in vitro companion diagnostic for the 
safe and effective use of the therapeutic product.

The three types of marketing pathways for medical devices are clearance of a premarket notification under Section 510(k) of the FDCA (“510(k)”), 
approval of a premarket approval application (“PMA”) and a de novo classification request, or de novo. If a company is required to perform clinical trials to 
support the safety and effectiveness of an IVD, and the IVD is viewed as a significant risk device, the sponsor will have to submit an investigational device 
exemption application (“IDE”) to the FDA, which is similar in format and function to an IND. If the diagnostic test and the therapeutic drug are studied 
together to support their respective approvals, any clinical trials involving both product candidates must meet both the IDE and IND requirements. 

The FDA expects that the therapeutic sponsor will address the need for an IVD companion diagnostic device in its therapeutic product development plan 
and that, in most cases, the therapeutic product and its corresponding IVD companion diagnostic device will be 

51

 
developed contemporaneously. If the companion diagnostic test will be used to make critical treatment decisions such as patient selection, treatment 
assignment, or treatment arm, it will likely be considered a significant risk device for which a clinical trial will be required. After approval, the use of an 
IVD companion diagnostic device with a therapeutic product will be stipulated in the instructions for use in the labeling of both the diagnostic device and 
the corresponding therapeutic product. In addition, a diagnostic test that was approved through the PMA process, or one that was cleared through the 
510(k) process or reclassified through the de novo process, and placed on the market will be subject to many of the same regulatory requirements that apply 
to approved drugs. 

However, the FDA may decide that it is appropriate to approve such a therapeutic product without an approved or cleared in vitro companion diagnostic 
device when the drug or therapeutic biologic is intended to treat a serious or life-threatening condition for which no satisfactory alternative treatment exists 
and the FDA determines that the benefits from the use of a product with an unapproved or uncleared in vitro companion diagnostic device are so 
pronounced as to outweigh the risks from the lack of an approved or cleared in vitro companion diagnostic device. The FDA encourages sponsors 
considering developing a therapeutic product that requires a companion diagnostic to request a meeting with both relevant device and therapeutic product 
review divisions to ensure that the product development plan will produce sufficient data to establish the safety and effectiveness of both the therapeutic 
product and the companion diagnostic. Because the FDA’s policies on companion diagnostics is set forth only in guidance, this policy is subject to change 
and is not legally binding.

European Union Regulation of Drug Products

In addition to regulations in the United States, we are and will be subject, either directly or through our distribution partners, to a variety of regulations in 
other jurisdictions governing, among other things, clinical trials, the privacy of personal data and commercial sales and distribution of our products, if 
approved.

Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in non-U.S. countries prior to the 
commencement of clinical trials or marketing of the product in those countries. Certain countries outside of the United States have a process that requires 
the submission of a clinical trial application much like an IND prior to the commencement of human clinical trials. In Europe, for example, a clinical trial 
application (“CTA”), must be submitted to the competent national health authority and to independent ethics committees in each country in which a 
company plans to conduct clinical trials. Once the CTA is approved in accordance with a country’s requirements, clinical trials may proceed in that country. 
Under the EU Clinical Trials Regulation, a harmonized assessment and supervision process was implemented as of January 31, 2022 for clinical trials 
throughout the EU, via a Clinical Trials Information System (“CTIS”). The CTIS will contain the centralized EU portal and database for clinical trials 
conducted in the EU and will allow for a centralized review process. This harmonized submission process became mandatory for new CTA submissions to 
be filed beginning on February 1, 2023. Under the new centralized process, if the EU member state leading the CTA review approves or rejects the 
application, the decision will apply to all involved member states.

The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country, even 
though there is already some degree of legal harmonization in the EU member states resulting from the national implementation of underlying EU 
legislation. In all cases, the clinical trials are conducted in accordance with GCP and other applicable regulatory requirements.

To obtain a marketing license for a new drug or medicinal product in the European Union, the sponsor must obtain approval of a marketing authorization 
application (“MAA”). The way in which a medicinal product can be approved in the European Union depends on the nature of the medicinal product. As of 
January 31, 2020, the United Kingdom (“UK”) is no longer a member state of the EU, and therefore a separate MAA and approval will be required to 
market a medicinal product in the UK. The UK’s Medicines and Healthcare products Regulatory Agency (“MHRA”) has issued guidance regarding the 
requirements for licensing and marketing therapeutic drugs and biologics post-Brexit.

The centralized procedure results in a single marketing authorization granted by the European Commission that is valid across the European Union, as well 
as in Iceland, Liechtenstein, and Norway. The centralized procedure is compulsory for human drugs that: (i) are derived from biotechnology processes, 
such as genetic engineering, (ii) contain a new active substance indicated for the treatment of certain diseases, such as HIV/AIDS, cancer, diabetes, 
neurodegenerative diseases, autoimmune and other immune dysfunctions and viral diseases, (iii) are officially designated “orphan drugs” (drugs used for 
rare human diseases) and (iv) are advanced-therapy medicines, such as gene-therapy, somatic cell-therapy or tissue-engineered medicines. The centralized 
procedure may at the request of the applicant also be used for human drugs which do not fall within the above mentioned categories if (a) the human drug 
contains a new active substance which was not authorized in the European Community; or (b) the applicant shows that the medicinal product constitutes a 
significant therapeutic, scientific or technical innovation or that the granting of authorization in the centralized procedure is in the interests of patients or 
animal health at the European Community level.

Under the centralized procedure in the European Union, the maximum timeframe for the evaluation of a marketing authorization application by the EMA is 
210 days (excluding clock stops, when additional written or oral information is to be provided by the applicant in response to questions asked by the 
Committee for Medicinal Products for Human Use (“CHMP”)), with adoption of the actual marketing authorization by the European Commission 
thereafter. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a major public health 
interest from the point of view of therapeutic innovation, defined by three cumulative criteria: the seriousness of the disease to be treated; the absence of an 
appropriate alternative 

52

 
therapeutic approach, and anticipation of exceptional high therapeutic benefit. In this circumstance, EMA ensures that the evaluation for the opinion of the 
CHMP is completed within 150 days and the opinion issued thereafter.

The mutual recognition procedure (“MRP”) for the approval of human drugs is an alternative approach to facilitate individual national marketing 
authorizations within the European Union. Basically, the MRP may be applied for all human drugs for which the centralized procedure is not obligatory. 
The MRP is applicable to the majority of conventional medicinal products, and is based on the principle of recognition of an already existing national 
marketing authorization by one or more member states. In the MRP, a marketing authorization for a drug already exists in one or more member states of the 
European Union and subsequently marketing authorization applications are made in other European Union member states by referring to the initial 
marketing authorization. The member state in which the marketing authorization was first granted will then act as the reference member state. The member 
states where the marketing authorization is subsequently applied for act as concerned member states. After a product assessment is completed by the 
reference member state, copies of the report are sent to all member states, together with the approved summary of product characteristics, labeling and 
package leaflet. The concerned member states then have 90 days to recognize the decision of the reference member state and the summary of product 
characteristics, labeling and package leaflet. National marketing authorizations within individual member states shall be granted within 30 days after 
acknowledgement of the agreement.

Should any member state refuse to recognize the marketing authorization by the reference member state, on the grounds of potential serious risk to public 
health, the issue will be referred to a coordination group. Within a timeframe of 60 days, member states shall, within the coordination group, make all 
efforts to reach a consensus. If this fails, the procedure is submitted to an EMA scientific committee for arbitration. The opinion of this EMA committee is 
then forwarded to the Commission, for the start of the decision-making process. As in the centralized procedure, this process entails consulting various 
European Commission Directorates General and the Standing Committee on Human Medicinal Products or Veterinary Medicinal Products, as appropriate.

European Union Regulation of IVD Products

In May 2022, the In Vitro Diagnostic Device Regulation (IVDR) (EU) 2017/746 became effective, replacing the previous IVD Directive (EU-Directive 
98/79/EC). The IVDR was published in May 2017 and given a five-year transition period until its full implementation on May 26, 2022. Unlike the IVD 
Directive, the IVDR has binding legal force throughout every Member State. The major goals of the IVDR are to standardize diagnostic procedures within 
the EU, increase reliability of diagnostic analysis and enhance patient safety. Among other things, the IVDR introduces a new risk-based classification 
system for IVDs and requirements for IVD conformity assessments. Under the IVDR and subsequent amendments, IVDs already certified by a Notified 
Body may remain on the market until May 26, 2025, and IVDs certified without the involvement of a Notified Body may remain on the market for up to 
two additional years (until May 26, 2027) depending on the classification of the IVD. The manufacturers of such devices remaining on the market must 
comply with specific requirements in the IVDR, but ultimately, such products, as with all new IVDs, will have to undergo the IVDR’s conformity 
assessment procedures. In addition, IVDs in the highest risk class will have to be tested by a Designated Reference Laboratory. The IVDR imposes 
additional requirements relating to post-market surveillance and submission of post-market performance follow-up reports.

The EC has designated six Notified Bodies to perform conformity assessments under the IVDR. MedTech Europe has issued guidance relating to the IVDR 
in several areas, e.g., clinical benefit, technical documentation, state of art, accessories, and EUDAMED.

Rest of World Government Regulation

For countries outside of the United States and the European Union, such as countries in Eastern Europe, Latin America or Asia, the requirements governing 
the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical trials must be conducted 
in accordance with GCP and the other applicable regulatory requirements.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension of clinical trials, 
suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions, and criminal prosecution.

Other Healthcare Laws 

Although we currently do not have any products on the market, if our product candidates are approved in the United States, we will have to comply with 
various U.S. federal and state laws, rules and regulations pertaining to healthcare fraud and abuse, including anti-kickback laws and physician self-referral 
laws, rules and regulations. Violations of the fraud and abuse laws are punishable by criminal and civil sanctions, including, in some instances, exclusion 
from participation in federal and state healthcare programs, including Medicare and Medicaid. These laws include the following:

•

the federal Anti-Kickback Statute prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or 
providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, 
order or recommendation of, any good or service, for which payment may be made, in whole or in part, under a federal healthcare program 
such as Medicare and Medicaid;

53

 
•

•

•

•

•

•

the federal False Claims Act imposes civil penalties, and provides for civil whistleblower or qui tam actions, against individuals or entities 
for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a 
false statement to avoid, decrease or conceal an obligation to pay money to the federal government;

the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) imposes criminal and civil liability for executing a 
scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, also 
imposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of 
individually identifiable health information;

the federal false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any 
materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;

the federal transparency requirements under the Physician Payments Sunshine Act require manufacturers of FDA-approved drugs, devices, 
biologics and medical supplies covered by Medicare or Medicaid to report, on an annual basis, to the Department of Health and Human 
Services information related to payments and other transfers of value to physicians, teaching hospitals, and certain advanced non-physician 
health care practitioners and physician ownership and investment interests; and

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing 
arrangements and claims involving healthcare items or services reimbursed by nongovernmental third-party payors, including private 
insurers.

Some state laws require pharmaceutical or medical device companies to comply with the relevant industry’s voluntary compliance guidelines and the 
relevant compliance guidance promulgated by the federal government in addition to requiring drug manufacturers to report information related to payments 
to physicians and other health care providers or marketing expenditures.

In November 2020, the Department of Health and Human Services (“DHHS”) finalized significant changes to the regulations implementing the Anti-
Kickback Statute, as well as the civil monetary penalty rules regarding beneficiary inducements, with the goal of offering the healthcare industry more 
flexibility and reducing the regulatory burden associated with those fraud and abuse laws, particularly with respect to value-based arrangements among 
industry participants. 

State and foreign laws also govern the privacy and security of health information in some circumstances, many of which differ from each other in 
significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. We also are subject to, or may in the future become subject 
to, U.S. federal and state, and foreign laws and regulations imposing obligations on how we collect, use, disclose, store and process personal information. 
Our actual or perceived failure to comply with such obligations could result in liability or reputational harm and could harm our business.

Pharmaceutical Coverage, Pricing, and Reimbursement 

Significant uncertainty exists as to the coverage and reimbursement status of products approved by the FDA and other government authorities. Sales of our 
products, when and if approved for marketing in the United States, will depend, in part, on the extent to which our products will be covered by third-party 
payors, such as federal, state, and foreign government healthcare programs, commercial insurance and managed healthcare organizations. The process for 
determining whether a payor will provide coverage for a product may be separate from the process for setting the price or reimbursement rate that the payor 
will pay for the product once coverage is approved. Third-party payors may limit coverage to specific products on an approved list, or formulary, which 
might not include all of the approved products for a particular indication. In addition, these third-party payors are increasingly reducing reimbursements for 
medical products, drugs and services. Furthermore, the U.S. government, state legislatures and foreign governments have continued implementing cost 
containment programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic products. 
Adoption of price controls and cost containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, 
could further limit our net revenue and results. Limited third-party reimbursement for our product candidates or a decision by a third-party payor not to 
cover our product candidates could reduce physician usage of our products once approved and have a material adverse effect on our sales, results of 
operations and financial condition. 

54

 
In Europe and other countries outside of the United States, pricing and reimbursement schemes vary widely from country to country. Some countries 
provide that drug products may be marketed only after a reimbursement price has been agreed to. Some countries may require the completion of additional 
studies that compare the cost-effectiveness of a particular product candidate to currently available therapies. In some countries, cross-border imports from 
low-priced markets exert competitive pressure that may reduce pricing within a country. Any country that has price controls or reimbursement limitations 
for drug products may not allow favorable reimbursement and pricing arrangements.

Healthcare Reform 

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes 
regarding the healthcare system that could prevent or delay marketing approval of product and therapeutic candidates, restrict or regulate post-approval 
activities, and affect the ability to profitably sell product and therapeutic candidates that obtain marketing approval. The FDA’s and other regulatory 
authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our 
product and therapeutic candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, 
or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we otherwise may have obtained and we may not achieve 
or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations. Moreover, among policy makers 
and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing 
healthcare costs, improving quality and/or expanding access. 

For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, the “ACA”), 
was enacted in March 2010 and has had a significant impact on the health care industry in the United States. The ACA expanded coverage for the 
uninsured while at the same time containing overall healthcare costs. With regard to biopharmaceutical products, the ACA, among other things, addressed a 
new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, 
instilled, implanted or injected, increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended 
the rebate program to individuals enrolled in Medicaid managed care organizations, established annual fees on manufacturers of certain branded 
prescription drugs, and created a new Medicare Part D coverage gap discount program. Additionally, on December 20, 2019, the Further Consolidated 
Appropriations Act for 2020 was signed into law (P.L. 116-94) and includes a piece of bipartisan legislation called the Creating and Restoring Equal Access 
to Equivalent Samples Act of 2019 or the “CREATES Act.” The CREATES Act aims to address the concern articulated by both the FDA and others in the 
industry that some brand manufacturers have improperly restricted the distribution of their products, including by invoking the existence of a REMS for 
certain products, to deny generic product developers access to samples of brand products. Because generic product developers need samples to conduct 
certain comparative testing required by the FDA, some have attributed the inability to timely obtain samples as a cause of delay in the entry of generic 
products. To remedy this concern, the CREATES Act establishes a private cause of action that permits a generic product developer to sue the brand 
manufacturer to compel it to furnish the necessary samples on “commercially reasonable, market-based terms.” Whether and how generic product 
developments will use this new pathway, as well as the likely outcome of any legal challenges to provisions of the CREATES Act, remain highly uncertain 
and its potential effects on any of our future commercial products are unknown.

Since the enactment of the ACA, there have been executive, judicial and Congressional challenges to certain aspects and as a result certain sections of the 
ACA have not been fully implemented or have been effectively repealed through Executive Orders and/or executive agency actions. However, following 
several years of litigation in the federal courts, in June 2021, the U.S. Supreme Court upheld the ACA when it dismissed a legal challenge to the ACA’s 
constitutionality. Further legislative and regulatory changes under the ACA remain possible, although the Biden Administration has signaled that it plans to 
build on the ACA and expand the number of people who are eligible for health insurance subsidies under it. It is unknown what form any such changes or 
any law would take, and how or whether it may affect the biopharmaceutical industry as a whole or our business in the future. We expect that changes or 
additions to the ACA, the Medicare and Medicaid programs, and changes stemming from other healthcare reform measures, especially with regard to 
healthcare access, financing or other legislation in individual states, could have a material adverse effect on the health care industry in the United States. 

In addition, other legislative changes have been proposed and adopted in the United States since the ACA that affect health care expenditures. These 
changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year pursuant to the Budget Control Act of 2011, which 
began in 2013 and was extended by the Consolidated Appropriations Act for 2023, and will remain in effect through 2032 unless additional Congressional 
action is taken. 

Moreover, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has 
resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency 
to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement 
methodologies for drug products. In May 2019, DHHS issued a final rule to allow Medicare Advantage plans the option to use step therapy for Part B 
drugs beginning January 1, 2020. This final rule codified a DHHS policy change that was effective January 1, 2019. 

55

 
More recently, in August 2022, President Biden signed into the law the Inflation Reduction Act of 2022, or the IRA. Among other things, the IRA has 
multiple provisions that may impact the prices of drug products that are both sold into the Medicare program and throughout the United States. Starting in 
2023, a manufacturer of a drug or biological product covered by Medicare Parts B or D must pay a rebate to the federal government if the drug product’s 
price increases faster than the rate of inflation. This calculation is made on a drug product by drug product basis and the amount of the rebate owed to the 
federal government is directly dependent on the volume of a drug product that is paid for by Medicare Parts B or D. Additionally, starting in payment year 
2026, CMS will negotiate drug prices annually for a select number of single source Part D drugs without generic or biosimilar competition. CMS will also 
negotiate drug prices for a select number of Part B drugs starting for payment year 2028. If a drug product is selected by CMS for negotiation, it is 
expected that the revenue generated from such drug will decrease. 

Individual states in the United States have also increasingly passed legislation and implemented regulations designed to control pharmaceutical product 
pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and 
transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In December 2020, the U.S. 
Supreme Court held unanimously that federal law does not preempt the states’ ability to regulate pharmaceutical benefit managers (“PBMs”) and other 
members of the health care and pharmaceutical supply chain, an important decision that may lead to further and more aggressive efforts by states in this 
area.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, 
either in the United States or abroad. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which 
could limit the amounts that federal and state governments will pay for healthcare products and services, including any future drug products for which we 
secure marketing approval. 

Manufacturing Requirements 

We and our third-party manufacturers must comply with applicable cGMP requirements. The cGMP requirements include requirements relating to, among 
other things, organization of personnel, buildings and facilities, equipment, control of components and drug product containers and closures, production 
and process controls, packaging and labeling controls, holding and distribution, laboratory controls, records and reports, and returned or salvaged products. 
The manufacturing facilities for our products must meet cGMP requirements to the satisfaction of the FDA pursuant to a pre-approval inspection before we 
can use them to manufacture commercial products. We and our third-party manufacturers are also subject to periodic announced or for-cause unannounced 
inspections of facilities by the FDA and other authorities, including procedures and operations used in the testing and manufacture of our commercial 
products, if any, to assess our compliance with applicable regulations. Failure to comply with statutory and regulatory requirements subjects a manufacturer 
to possible legal or regulatory action, including, among other things, warning or other enforcement letters, voluntary corrective action, the seizure of 
products, injunctions, consent decrees placing significant restrictions on or suspending manufacturing operations, disgorgement of profits, and other civil 
and criminal penalties. 

Other Regulatory Requirements 

We are also subject to various laws and regulations regarding laboratory practices, the experimental use of animals, and the use and disposal of hazardous 
or potentially hazardous substances in connection with our research. In each of these areas, as above, the FDA has broad regulatory and enforcement 
authority, including, among other things, the ability to levy fines and civil penalties, suspend or delay issuance of approvals, seize or recall products, and 
withdraw approvals, any one or more of which could have an adverse effect on our ability to operate our business and generate revenues. Compliance with 
applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, development and 
production efforts, which could harm our business, operating results and financial condition. 

Human Capital 

As of December 31, 2022, we employed 252 employees, of which 250 were full-time employees. A significant number of our management and 
professional employees have had prior experience with pharmaceutical, biotechnology or medical product companies. None of our employees are 
represented by a labor union or covered under a collective bargaining agreement. Management considers relations with our employees to be good. 

Our approach to how we recruit, develop, retain and manage our talent is driven by our values statement: Making an impact through innovation, inclusion, 
and inspiration. Our values are at the core of who we are as an organization, and what drive us to envision a brighter future for the patients and families we 
serve. Critical to achieving our strategic imperatives is our ability to build a world-class organization and retain an exceptional team in which each member 
plays a unique and important role. We value diversity, inclusion, and social responsibility where our employees have a strong sense of belonging and 
contributing, while being empowered to make a real difference. This commitment is company-wide and our Nominating and Corporate Governance 
Committee charter reflects the Nominating and Corporate Governance Committee’s oversight of our strategies and policies related to our people and 
diversity, equity 

56

 
and inclusion (“DEI”), in addition to the Nominating and Corporate Governance Committee’s oversight of our environmental, social and governance 
(“ESG”) strategy, initiatives and policies. 

We recognize that maintaining an engaged and high-performing workforce who share a connection with the communities we serve is critical to our success. 
Comradery and cohesion are at the core of who we are as a company, and are integral facets of our human capital strategy. Whether it is coming together 
throughout the year to connect at our town halls or participating in a global fitness challenge to support the health and well-being of our employees, we take 
a team approach to our work. We are inspired by the communities we serve, the opportunities to engage and learn from individuals and their families, and 
the possibilities of what we can achieve together. 

We understand that in order to drive innovation, we must continuously improve our people strategies and find ways to foster engagement and growth within 
our organization. To this end, below are some of our initiatives:

Employee Engagement: We embrace the idea that our employees do their best work when they have equity ownership in the business. Having an engaged 
and dedicated workforce is essential for us to achieve our goals. Employee engagement ensures that our employees feel passionate about the work they are 
doing, and with this commitment, we recognize that this is when results happen. It is more apparent than ever that we are all in this together, and as a 
company, we need to set up our employees for success and continue to cultivate their engagement with our company. We regularly conduct surveys as a 
means of engaging with employees and gaining their insights. We use the data and input as a tool for improving our human resources management going 
forward. Engagement is also directly correlated to the interactions our employees have with each other and their teams. Our Wave Activities Committee is a 
cross-functional team dedicated to organizing activities, such as themed social gatherings, charity and volunteer opportunities, and health and wellness 
events, which enrich our culture and bring employees together. We also work to ensure that we are deeply aligned with our corporate goals as a company, 
that functional goals are clear and transparent, and that employees understand how their work contributes to the company’s success.

Employee Health and Safety: Compliance with environmental, health and safety (“EH&S”) laws and regulations forms the basis of the EH&S policy and 
programs we have in place, which include occupational health and safety measures that apply to all of our employees, contractors and visitors. These 
programs detail the proactive, risk-based approach that we take to prevent workplace injuries and protect the health and safety of our employees and the 
communities around us. We have implemented an EH&S management system to monitor and track the effectiveness of our programs, ensure EH&S 
compliance, respond to incidents and manage corrective actions to reinforce safeguards. Our training programs provide training to our employees that is 
commensurate with their level of risk exposure and are designed to ensure that employees have the knowledge and equipment available to mitigate risk. 
Our cross-functional Safety Committee meets monthly to discuss any concerns and ways to improve our EH&S programs. Employees are also required to 
report any incidents, no matter how small, and are encouraged to voice any health or safety concerns to management or a member of our EH&S team. As 
we continue to monitor the COVID-19 situation, we have implemented and will continue to implement measures designed to safeguard the health and 
safety of our employees and our patients, which includes our mandatory COVID-19 vaccination policy.

Professional Development Programs and Opportunities: Employees are our most valuable resource, and we aspire to provide them with opportunities so 
that they can continue to grow and excel in their functions and our company. Professional growth of our employees leads to engagement and development, 
and allows us to leverage opportunities to hire and promote key talent from within our organization. We have also implemented a personal development 
plan program, and leadership and management development programs, which we recognize is a critical part of our future success. In 2022, we initiated 
“Building Coaching Leaders,” a learning series designed to build strong coaching capabilities and strengthen a manager’s engagement with their teams. 
Through development planning, we strive for employees at all levels to focus on strengthening the skills required in their current role and potentially their 
next role. We conduct annual performance reviews for all employees, but, as importantly, we are focused on building a culture of continuous coaching, 
feedback and open communication between managers and their direct reports throughout the entire year. We provide managers and employees with training 
on how to conduct effective forward-looking performance conversations and to set effective goals that are specific, measurable, attainable, relevant and 
timebound (SMART). We provide our employees with unlimited access to LinkedIn Learning, to advance their professional development, interests and 
goals. Another example where we provide company-wide leadership and development opportunities is through the Wave Learning Series, which was 
developed to build awareness of all functional areas, special areas of interest or importance, timely subject matters and to expand knowledge of industry 
trends and other matters of interest and relevance within the biopharmaceutical industry. The Wave Learning Series is conducted through company-wide 
presentations by employees at various levels, providing opportunities for development and cross-functional exposure for our employees. To further assist 
our employees, we also offer all full-time employees the option to participate in our Education Assistance Program, where we reimburse employees for 
tuition and eligible expenses.

Health and Well-Being: We believe that the overall well-being of our employees and ensuring that their basic health and wellness needs are met, is 
fundamental for us to achieve success as a company. We understand that a key part of our ongoing efforts to prioritize wellness initiatives, includes 
providing our employees with access to mental health, behavioral health, and/or substance abuse services through our medical plans. We provide an 
Employee Assistance Program (“EAP”), as a cost-free benefit, which is available to help employees and their household members confidentially manage 
everyday life, work challenges, stress, and other 

57

 
personal issues, by providing consultation, referrals and resources, along with ongoing webinars on various work-life, mental health and wellness topics for 
employees. In addition, we understand that workplace flexibility is an important component to our employees’ well-being. Throughout the COVID-19 
pandemic, safeguarding employee and patient health has been our top priority, as we advance our business through the research and development of our 
therapeutic candidates. Prioritizing employee safety while achieving our goals has provided us with a greater appreciation for workplace flexibility, which 
keeps our employees engaged and motivated, while also creating a sense of trust throughout our organization.

Diversity, Equity and Inclusion (“DEI”): Our commitment to maintaining a top-performing company means investing in and creating ongoing opportunities 
for employee development in a diverse and inclusive workplace. We provide equal employment opportunities without regard to race, color, religion, 
gender, sexual orientation, national origin, age, disability, veteran status or genetics. In 2021, we formalized our DEI efforts through various initiatives, 
including the formation of a DEI Steering Group to be intentional about creating and maintaining a diverse, equitable, culturally competent and supportive 
environment for all of our employees and other stakeholders. Some of our preliminary DEI initiatives included creating opportunities for our employees to 
be engaged with our DEI initiatives through participation in a cultural assessment survey and creating various focus groups. The data we received from this 
preliminary work enabled us to create a DEI strategy and define our strategic DEI goals to enhance our overall awareness of DEI and elevate our inclusive 
leadership and workplace through a broad range of initiatives. Our DEI Steering Group also defined our DEI Vision: At Wave we celebrate diversity and the 
power of unique perspectives. Together, we are building an inclusive and empowered culture where everyone is valued, able to thrive and feels a sense of 
belonging. By embracing our differences, we inspire each other, spark innovation and drive meaningful impact for our patients, their families and the 
communities that we serve. Our DEI Vision will guide us as we further our understanding of the DEI matters that affect our company and stakeholders, and 
take the appropriate actions to achieve our goals.

We believe that a diverse and inclusive workforce positively impacts our performance, fosters innovation and inspires us to achieve greater results. In 
addition to this, our intentional focus on DEI continues to strengthen our culture and helps ensure that we continue to cultivate an effective next generation 
of experienced leaders and managers necessary to execute on our mission and plans for ambitious growth. Hiring for diversity of thought, background and 
experience, and diversity of personal characteristics such as gender, race and ethnicity, among many others, is intentional, and continues to be an area of 
focus for us as we build and grow our workforce. Despite the historical lack of institutional emphasis on the importance of girls and women focusing on 
education in science, technology, engineering and mathematics (“STEM”) and the resulting disproportionate occupation by men in the STEM-educated 
talent pool, we have prioritized and hired a gender diverse workforce. As of December 31, 2022, women made up approximately 53% of our global 
workforce and constitute approximately 48% of senior management (defined as vice president level and above). We are also committed to building a 
racially and ethnically diverse workforce. As of December 31, 2022, racially diverse employees (those self-identifying as Black or African American, 
Hispanic or Latinx, Asian, or being of two or more races) make up approximately 36% of our global workforce and approximately 22% of senior 
management (defined as vice president level and above) (20% of our employees did not provide us with this information). In addition, we continue to 
partner with Project Onramp, which is an organization that is working to bridge the opportunity gap for Massachusetts college students in underserved and 
minority communities. Through this partnership, we provide students with summer internships.

Community Outreach and Engagement: Our community engagement activities are focused on seeking to better understand the lives of people living with 
rare disease and identifying opportunities to support the rare disease community. We believe that partnering with, and understanding the lives of individuals 
impacted by disease and their families and caregivers, connects us more deeply to our mission, differentiates us and enhances our ability to discover and 
develop potential therapies. Through collaboration with patient communities and advocacy organizations, and participation in community-focused 
conferences and events, we aim to broaden our understanding of the lived experiences of these individuals and families and to incorporate their 
perspectives into every aspect of our work. These insights inform the design and execution of our clinical trials, the enrichment of our corporate culture, 
and other initiatives that make a positive impact on people’s lives. Employee volunteerism is another important component of our community engagement 
initiatives. We partner with advocacy and service organizations to provide opportunities for employees to contribute directly to our local communities, 
including through our Wave Service Day and holiday giving drives. By participating in a broad range of volunteer activities, our employees donate time 
and resources to support individuals and families in the rare disease community and beyond. We also recognize that external factors and current events, 
including systems and policies, impact our employees, as well as the communities with which we are connected. We prioritize providing mental health 
resources for our employees, creating forums for dialogue, and finding opportunities to give back to impacted groups.

Rewards and Recognition: We have a multi-tiered awards program, including peer-to-peer recognition, which our employees use to recognize and reward 
one another for their contributions and achievements, taking into consideration the combination of employees who best exemplify our values and the 
achievement of results. We believe that providing a rewards program not only increases engagement and performance, but meaningfully recognizes those 
employees who go above and beyond to positively impact our company and culture. In addition, we offer a team rewards and recognition program to 
provide another opportunity to recognize and reward collaborative teamwork.

58

 
Compensation, Equity and Benefits (Total Rewards): Compensation programs are one of the most powerful tools available to companies to attract, retain 
and motivate employees, as well as align their interests with those of shareholders. We have developed a broad-based compensation program that is 
designed to attract, retain and motivate our employees, while driving sustainable long-term value creation. We seek to deliver performance-driven, market 
competitive reward opportunities commensurate with company and individual performance. All of our employees receive competitive base salaries, cash 
bonuses, new hire equity grants and annual long-term incentive grants, in addition to our comprehensive benefits package. We believe that providing 
employees with an ownership interest in our company through grants of equity awards, further strengthens the level of employee engagement. Furthermore, 
equity awards help align the interests of our employees with the long-term interests of our shareholders. In addition, we have an Employee Share Purchase 
Plan (“ESPP”), which provides our employees with an opportunity to purchase shares of our Company at a 15% discount to the market price. 

Offering a highly competitive, industry-leading, benefits package is another integral piece of our total rewards package and differentiated employee value 
proposition. Notably, we provide our employees with access to choice and offer employees a very progressive health insurance package, with no premiums. 
We also offer a 401(k) plan with matching contributions for all eligible employees. We continue to provide innovative solutions that are key to attracting, 
engaging and motivating employees, including (i) our excellent benefits and compensation programs and strategies; (ii) our employee well-being approach 
and strategy; (iii) our health plan and how we have managed this over time; and (iv) internal communications and education around our total rewards 
strategy.

We will continue to evolve and strengthen our strategies relating to talent, while furthering our investment in our employees, culture, community 
partnerships and outreach, and other human capital measures.

Note on the COVID-19 Global Pandemic 

The ongoing COVID-19 global pandemic, and variants thereof, continues to have widespread, rapidly evolving, and unpredictable impacts on global 
societies, economies, financial markets, and business practices. We are closely monitoring the impact of the pandemic and related developments, and our 
focus remains on safeguarding employee and patient health, while minimizing the negative effects on our business and continuing to advance the research 
and development of our therapeutic candidates. For discussion regarding the impact of the COVID-19 global pandemic on our business and financial 
results, see “Risk Factors” in Part I, Item 1A and “Management's Discussion and Analysis of Financial Condition and Results of Operations” in Part II,

Item 1A. Risk Factors 

Risk Factors 

You should carefully consider the following risk factors, in addition to the other information contained in this Annual Report on Form 10-K, including the 
section of this report titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and 
related notes. If any of the events described in the following risk factors and the risks described elsewhere in this Annual Report on Form 10-K occurs, our 
business, operating results and financial condition could be seriously harmed and the trading price of our ordinary shares could decline. This Annual 
Report on Form 10-K also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those 
anticipated in the forward-looking statements as a result of factors that are described below and elsewhere in this Annual Report on Form 10-K. 

Risks Related to Our Financial Results and Capital Requirements 

We are a clinical-stage genetic medicines company with a history of losses, and we expect to continue to incur losses for the foreseeable future, and we 
may never achieve or maintain profitability. 

We are a clinical-stage genetic medicines company and have incurred significant operating losses since our incorporation in 2012. Our net loss was $161.8 
million and $122.2 million for the fiscal years ended December 31, 2022 and 2021, respectively. As of December 31, 2022 and 2021, we had an 
accumulated deficit of $967.3 million and $805.5 million, respectively. To date, we have not generated any product revenue. Substantially all of our losses 
have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with 
our operations. 

We currently have no products on the market and expect that it may be many years, if ever, before we have a product candidate ready for 
commercialization. We have a robust and diverse pipeline of PN-modified, stereopure oligonucleotides, including programs using our editing, splicing, and 
silencing modalities. Our lead clinical programs are focused in, and aim to address, muscle diseases (DMD – splicing), hepatic diseases (AATD – editing), 
and CNS diseases (HD, ALS and FTD – silencing). We have not generated, and do not expect to generate, any product revenue for the foreseeable future, 
and we expect to continue to incur significant operating losses for the foreseeable future due to the cost of research and development, manufacturing, 
preclinical studies and clinical trials and the regulatory review process for product candidates. The amount of future losses is uncertain. To achieve 
profitability, we must successfully develop product candidates, obtain regulatory approvals to market and commercialize product candidates, manufacture 
any approved product candidates on commercially reasonable terms, establish a sales and marketing organization or suitable third-party alternatives for any 
approved product and raise sufficient funds to finance our business activities. We may never succeed in these activities and, even if we do, may never 
generate revenues that are significant or large enough to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase 
profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our company and could impair our 
ability to raise capital, maintain our research and development efforts, expand our business or continue our operations. A decline in the value of our 
company could also cause our shareholders to lose all or part of their investment. 

We will require substantial additional funding, which may not be available on acceptable terms, or at all. 

We have used substantial funds to develop our programs and PRISM, our proprietary discovery and drug development platform, and will require 
substantial funds to conduct further research and development, including preclinical studies and clinical trials of our product candidates, seek regulatory 
approvals for our product candidates and manufacture and market any products that are approved for commercial sale. We believe that our existing cash 
and cash equivalents will be sufficient to fund our operations for at least the next 12 months. 

Our future capital requirements and the period for which we expect our existing resources to support our operations may vary significantly from what we 
expect. We do not expect to realize any appreciable revenue from product sales or royalties in the foreseeable future, if at all. Our revenue sources will 
remain extremely limited unless and until our product candidates complete clinical development and are approved for commercialization and successfully 
marketed. Because we cannot be certain of the length of time or activities associated with successful development and commercialization of our product 
candidates, we are unable to estimate the actual funds we will require to develop and commercialize them. 

Our future capital requirements will depend on many factors, including, but not limited to, the following:

•

•

•

our monthly spending levels, based on new and ongoing development and corporate activities; 

the scope, progress, results and costs of drug discovery, preclinical and clinical development for our product candidates;

our ability to establish and maintain collaboration arrangements, and whether our collaboration partners decide to exercise option rights in 
connection with targets and development programs;

61

 
•

•

•

•

•

•

•

•

•

the costs, timing and outcome of regulatory review of our product candidates; 

our ability to obtain marketing approval for our product candidates;

the impacts of the COVID-19 global pandemic (and emerging or future variants of COVID-19) on our business;

the achievement of milestones and other development targets that trigger payments under our agreements with our key collaboration partners, or 
any other strategic collaborations into which we may enter;

the extent to which we are obligated to reimburse clinical trial costs or expenses and other costs and expenses associated with clinical activities 
under our agreements with our key collaboration partners, or any other future collaboration agreements, if any; 

the costs and timing of future commercialization activities, including manufacturing, marketing, sales and distribution, for any of our product 
candidates for which we receive marketing approval;

market acceptance of our product candidates, to the extent any are approved for commercial sale, and the revenue, if any, received from 
commercial sales of our product candidates for which we receive marketing approval;

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and 
defending any intellectual property-related claims;

the costs of securing manufacturing arrangements internally or with third parties for drug supply.

To date, we have primarily financed our operations through sales of our securities and our collaborations with third parties. Through December 31, 2022, 
we have received an aggregate of approximately $1,021.2 million in net proceeds from these transactions, consisting of $630.9 million in net proceeds from 
public and other registered offerings of our ordinary shares, $301.0 million from our collaborations, exclusive of any potential future milestone and royalty 
payments, and $89.3 million in net proceeds from private placements of our debt and equity securities. Subsequent to December 31, 2022, we received 
$170.0 million in cash, of which $120.0 million was an upfront payment under the GSK Collaboration Agreement and $50.0 million was under the GSK 
Equity Investment. 

On March 3, 2022, we filed a new universal shelf registration on Form S-3 with the SEC, which was declared effective by the SEC on May 4, 2022, 
pursuant to which we registered for sale up to $500.0 million of any combination of our ordinary shares, debt securities, warrants, rights and/or units from 
time to time and at prices and on terms that we may determine, which we refer to as the “2022 Form S-3.” The 2022 Form S-3 includes a prospectus 
covering up to approximately $132.0 million in ordinary shares that had not yet been issued or sold under our Sales Agreement with Jefferies LLC 
(“Jefferies”) for our “at-the-market” equity program. As of March 22, 2023, we have $430.0 million in securities available for issuance under the 2022 
Form S-3, including approximately $132.0 million in ordinary shares available for issuance under our at-the-market equity program. As of March 22, 2023, 
we have received approximately $118.0 million in gross proceeds from our at-the-market equity program. We intend to seek additional funding in the future 
through collaborations, public or private equity offerings or debt financings, credit or loan facilities or a combination of one or more of these financing 
sources. 

Our ability to raise additional funds will depend on financial, economic and other factors, many of which are beyond our control. We may seek access to 
the capital and credit markets for working capital, capital expenditure, and other business initiatives. The capital and credit markets have experienced 
extreme volatility and disruption, which may lead to uncertainty and liquidity issues for both borrowers and investors. In the event of adverse market 
conditions, or other factors, additional funds may not be available to us on acceptable terms or at all. For example, the global economy has been 
experiencing increasing interest rates and inflation, which could negatively impact our business and our ability to raise additional funds. If we raise 
additional funds by issuing equity or convertible debt securities, our shareholders will suffer dilution and the terms of any financing may adversely affect 
the rights of our shareholders. In addition, as a condition to providing additional funds to us, future investors may demand, and may be granted, rights 
superior to those of existing shareholders. Debt financing, if available, may involve restrictive covenants limiting our flexibility in conducting future 
business activities, and, in the event of insolvency, debt holders would be repaid before holders of equity securities received any distribution of corporate 
assets. 

If we are unable to obtain funding on a timely basis or on acceptable terms, we may have to delay, limit or terminate our research and development 
programs and preclinical studies or clinical trials, limit strategic opportunities or undergo reductions in our workforce or other corporate restructuring 
activities. We also could be required to seek funds through arrangements with collaborators or others that may require us to relinquish rights to some of our 
product candidates or technologies that we would otherwise pursue on our own. 

Our business may be impacted by macroeconomic conditions, including fears concerning the financial services industry, inflation, rising interest rates 
and volatile market conditions, and other uncertainties beyond our control. 

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional 
counterparties or other companies in the financial services industry or the financial services industry generally, or 

62

 
concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For 
example, on March 10, 2023, Silicon Valley Bank failed and was taken into receivership by the Federal Deposit Insurance Corporation; on March 12, 2023, 
Signature Bank and Silvergate Capital Corp. were each swept into receivership;

the following week, a syndicate of U.S. banks infused $30 billion in First Republic Bank; and later that same week, the Swiss Central Bank provided $54 
billion in covered loan and short-term liquidity facilities to Credit Suisse Group AG, all in an attempt to reassure depositors and calm fears of a banking 
contagion. Our ability to effectively run our business could be adversely affected by general conditions in the global economy and in the financial services 
industry. Various macroeconomic factors could adversely affect our business, including fears concerning the banking sector, changes in inflation, interest 
rates and overall economic conditions and uncertainties. A severe or prolonged economic downturn could result in a variety of risks, including our ability 
to raise additional funding on a timely basis or on acceptable terms. A weak or declining economy could also impact third parties upon whom we depend to 
run our business. Increasing concerns over bank failures and bailouts and their potential broader effects and potential systemic risk on the banking sector 
generally and on the biotechnology industry and its participants may adversely affect our access to capital and our business and operations more generally. 
Although we assess our banking relationships as we believe necessary or appropriate, our access to funding sources in amounts adequate to finance or 
capitalize our current and projected future business operations could be significantly impaired by factors that affect us, the financial institutions with which 
we have arrangements directly, or the financial services industry or economy in general

Our management has broad discretion over the use of proceeds received from sales of our securities and our collaborations with third parties and the 
proceeds may not be used effectively. 

Our management has broad discretion as to the use of proceeds we receive from conducting sales of our securities and our collaborations with third parties 
and could use the proceeds for purposes other than those contemplated at the time of such transactions. It is also possible that the proceeds we have 
received, or may receive, from securities sales and collaborations will be invested in a way that does not yield a favorable, or any, return for us. 

Our short operating history may make it difficult for shareholders to evaluate the success of our business to date and to assess our future viability.

We are a clinical-stage genetic medicines company with a limited operating history. We commenced active operations in 2012. Our operations to date have 
primarily included research and development activities, manufacturing, preclinical and clinical development, patient advocacy activities, business planning 
and raising capital. We have a robust and diverse pipeline of PN-modified, stereopure oligonucleotides, including programs using our editing, splicing, and 
silencing modalities. Our lead clinical programs are focused in, and aim to address, muscle diseases (DMD – splicing), hepatic diseases (AATD – editing), 
and CNS diseases (HD, ALS and FTD – silencing). We have not yet demonstrated our ability to successfully complete pivotal clinical trials, obtain 
marketing approvals, or conduct sales and marketing activities necessary for successful product commercialization. We have limited experience 
manufacturing our products at commercial scale or arranging for a third party to do so on our behalf. Typically, it takes many years to develop and 
commercialize a therapeutic from the time it is discovered to when it is available for treating patients. Further, drug development is a capital-intensive and 
highly speculative undertaking that involves a substantial degree of risk. You should consider our prospects in light of the costs, uncertainties, delays and 
difficulties frequently encountered by biotechnology companies in the early stages of clinical development, such as ours. Any predictions about our future 
success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and 
commercializing pharmaceutical products. 

We, or third parties upon whom we depend, may face risks related to health epidemics, including the COVID-19 pandemic and variants thereof, which 
may delay our ability to complete our ongoing clinical trials, initiate additional clinical trials, delay regulatory activities and have other adverse effects 
on our business and operations. 

Since December 2019, multiple countries throughout the world and their economies, including the United States, have been subject to intermittent 
shutdowns and adversely affected by the COVID-19 global pandemic. We are continuing to evaluate any continued impacts from the global pandemic and 
the extent to which any responsive measures may materially and adversely affect our business operations and financial condition.

As a clinical-stage company with multiple programs and multiple clinical trials currently underway, the pandemic is impacting the execution of our clinical 
trials. We have clinical trial sites located in countries that have been affected by COVID-19 and variants thereof. Clinical site initiation and patient 
enrollment has been delayed due to prioritization of hospital resources in favor of COVID-19 patients and difficulties in recruiting clinical site investigators 
and clinical site staff. Some patients have not been able to travel or gain access to clinical trial sites due to local restrictions. Similarly, our ability to recruit 
and retain patients and principal investigators 

63

 
 
and site staff who, as healthcare providers, may have heightened risk of exposure to COVID-19, has been negatively impacted, which has delayed the 
timelines of our clinical trial operations. 

We rely upon third parties for many aspects of our business, including the raw materials used to make our product candidates and the conduct of our 
clinical trials and preclinical studies. While we have built up inventory to assist us through this uncertain operating environment, our suppliers may be 
disrupted now or in the future, which may affect our ability to procure items that are essential for our research and development activities and may cause 
pricing increases, inflation, and significant disruptions to our business.

The COVID-19 global pandemic, including any emerging variants of COVID-19, is continuing to evolve and is subject to change. While we have adapted 
our processes to lessen the impact that COVID-19, and variants thereof, may have on our business, any potential delays or long-term impacts on our 
business, our clinical trials, healthcare systems or the global economy are highly uncertain. These effects may materially adversely affect our business, 
financial condition, results of operations, and prospects.

Risks Related to the Discovery, Manufacturing, Development and Commercialization of Our Product Candidates 

The approach we are taking to discover and develop oligonucleotides is novel and may never lead to marketable products. 

We have concentrated our efforts and research and development activities on oligonucleotides and enhancing PRISM, our proprietary discovery and drug 
development platform. PRISM enables us to target genetically defined diseases with stereopure oligonucleotides across multiple therapeutic modalities. 
Our future success depends on the successful development of stereopure oligonucleotides and the effectiveness of PRISM. The scientific discoveries that 
form the basis for our efforts to discover and develop new product candidates, including our discoveries about the relationships between oligonucleotide 
stereochemistry and pharmacology, are relatively new. We use PRISM to screen candidates and optimize pharmacologic profiles based on predefined 
design principles, which reflect a deep understanding of how the interplay among oligonucleotide sequence, chemistry and backbone stereochemistry 
impacts key pharmacological properties. The scientific evidence to support the feasibility of developing medicines based on these discoveries is limited. 
Skepticism as to the feasibility of developing oligonucleotides generally has been, and may continue to be, expressed in scientific literature. In addition, 
decisions by other companies with respect to their oligonucleotide development efforts may increase skepticism in the marketplace regarding the potential 
for oligonucleotides. 

A number of clinical trials for oligonucleotide products conducted by other companies have not been successful, but some have received regulatory 
approval. The pharmacological properties ascribed to the investigational compounds we are testing in laboratory studies may not be positively 
demonstrated in clinical trials in patients, and they may interact with human biological systems in unforeseen, ineffective or harmful ways. If our product 
candidates prove to be ineffective, unsafe or commercially unviable, PRISM and our pipeline would have little, if any, value, which would substantially 
harm our business, financial condition, results of operations and prospects. In addition, our approach, which focuses on using oligonucleotides for drug 
development, as opposed to multiple or other, more advanced proven technologies, and new products and technologies that may enter the market, may 
expose us to additional financial risks and make it more difficult to raise additional capital if we are not successful in developing one or more 
oligonucleotides that receive regulatory approval. 

Because we are developing oligonucleotides, which are considered a relatively new class of drugs, there is increased risk that the outcome of our 
clinical trials will not be sufficient to obtain regulatory approval. 

The FDA and comparable ex-U.S. regulatory agencies have relatively limited experience with oligonucleotides, which may increase the complexity, 
uncertainty and length of the regulatory review process for our product candidates. To date, the FDA has approved 15 oligonucleotides for marketing and 
commercialization. Even though the FDA issued in December 2021 two draft guidance documents relating to IND submissions for individualized antisense 
oligonucleotide drugs for severely debilitating or life-threatening genetic diseases, one with clinical focus, the other with chemistry manufacturing and 
controls focus, and in June 2022 a draft guidance on clinical pharmacology considerations for the development of oligonucleotide therapeutics, the FDA 
and its foreign counterparts have not yet established any definitive policies, practices or guidelines in relation to overall development considerations for 
oligonucleotide drugs. The general lack of policies, practices or guidelines specific to oligonucleotides may hinder or slow review by the FDA or other 
foreign homologues of any regulatory filings that we may submit. Moreover, the FDA or other foreign homologues may respond to these submissions by 
defining requirements we may not have anticipated. Addressing such requirements could lead to significant delays in the development of our product 
candidates. In addition, because there may be approved treatments for some of the diseases for which we may seek approval, in order to receive regulatory 
approval, we may need to demonstrate through clinical trials that the product candidates we develop to treat these diseases, if any, are not only safe and 
effective, but safer or more effective than existing products. Furthermore, in recent years, there has been increased public and political pressure on the FDA 
with respect to the approval process for new drugs. As a result of the foregoing factors, we may never receive regulatory approval to market and 
commercialize any product candidate. 

Even if we obtain regulatory approval, the approval may be for disease indications or patient populations that are not as broad as we intended or desired or 
may require labeling that includes significant use or distribution restrictions or safety warnings. We may be 

64

 
required to perform additional or unanticipated clinical trials to obtain regulatory approval or be subject to additional post-marketing studies or other 
requirements to maintain such approval. As a result, we may never succeed in developing a marketable product, we may not become profitable and the 
value of our ordinary shares could decline. 

Our preclinical studies and clinical trials may not be successful. If we are unable to commercialize our product candidates or experience significant 
delays in doing so, our business will be materially harmed. 

We have a robust and diverse pipeline of PN-modified, stereopure oligonucleotides, including programs using our editing, splicing, and silencing 
modalities. Our lead clinical programs are focused in, and aim to address, muscle diseases (DMD – splicing), hepatic diseases (AATD – editing), and CNS 
diseases (HD, ALS and FTD – silencing). 

However, we currently have no products on the market. We have invested a significant portion of our efforts and financial resources in the identification 
and preclinical and clinical development of our oligonucleotides, the development of PRISM, including our ADAR editing capability, and our novel PN 
backbone chemistry modifications, and the continued growth of our manufacturing capabilities. Our ability to generate product revenue, which we do not 
expect will occur for many years, if ever, will depend heavily on the successful development, regulatory approvals, and eventual commercialization of our 
product candidates. Our success will depend on several factors, including the following: 

•

•

•

•

•

•

•

•

•

•

•

successfully completing preclinical studies and clinical trials; 

successfully conducting process development and manufacturing campaigns in accordance with cGMP; 

receiving regulatory approvals from applicable regulatory authorities to market our product candidates and, to the extent necessary, our 
companion diagnostic tests; 

establishing commercial manufacturing capabilities or making arrangements with third party CMOs; 

obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates; 

the degree to which we are successful in our current collaborations, and any additional collaborations we may establish; 

launching commercial sales of the products, if and when approved, whether alone or in collaboration with others;

acceptance of the products, if and when approved, by patients, the medical community and third-party payors; 

effectively competing with other therapies; 

continuing to maintain an acceptable safety and efficacy profile of the products following regulatory approval; and

appropriately addressing the post-marketing requirements and/or commitments made upon regulatory approval. 

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully 
commercialize our product candidates, which would materially harm our business. 

We may not be able to conduct clinical trials successfully due to various process-related factors that could negatively impact our business plans. 

The successful initiation and completion of any of our clinical trials, within timeframes consistent with our business plans, is dependent on various factors, 
which include, but are not limited to, our ability to:

•

•

•

•

•

•

retain and recruit employees, contractors or consultants with the required level of knowledge and experience;

retain and recruit in a timely manner a sufficient number of patients necessary to conduct a clinical trial, which is a function of many factors, 
including the impact of the COVID-19 global pandemic, the proximity of participants to clinical sites, the size of the relevant population, the 
eligibility criteria for the trial, possible adverse effects from treatments, the existence of competing clinical trials, the involvement of patient 
advocacy groups, the availability of new or alternative treatments, lack of efficacy, personnel issues and ease of participation in our clinical trials; 

manage the impact of the COVID-19 pandemic on our early-stage discovery efforts and clinical trials;

open study sites, and enroll, treat, and monitor patients due to local restrictions implemented in response to the COVID-19 or other global health 
pandemics; 

develop companion diagnostic tests for use with certain of our product candidates or identify partners with such expertise;

manufacture and maintain a sufficient amount of clinical material, internally or through third parties;

65

 
 
•

•

•

•

•

•

ensure adherence to trial designs and protocols agreed upon and approved by regulatory authorities and applicable regulatory and legal 
guidelines; 

apply the appropriate pharmacovigilance measures in case of adverse effects emerging during a clinical trial; 

execute clinical trial designs and protocols approved by regulatory authorities without deficiencies; 

timely and effectively contract with (under reasonable terms), manage and work with investigators, institutions, hospitals and the contract 
research organizations (“CROs”) involved in the clinical trial; 

negotiate contracts and other related documents with clinical trial parties and institutional review boards (“IRBs”), CRO agreements and site 
agreements, which can be subject to extensive negotiations that could cause significant delays in the clinical trial process, with terms possibly 
varying significantly among different trial sites and CROs and possibly subjecting us to various risks; and 

conduct clinical trials in a cost-effective manner, including management of foreign currency risk in clinical trials conducted in foreign 
jurisdictions and cost increases due to unforeseen or unexpected complications such as enrollment delays, or needing to outsource certain 
functions during the clinical trial. 

If we are not able to manage the clinical trial process successfully, our business plans could be delayed or be rendered unfeasible for us to execute within 
our planned or required time frames, or at all. 

If we cannot successfully manufacture our product candidates for our research and development and preclinical activities, or manufacture sufficient 
amounts of our product candidates to meet our clinical requirements and timelines, our business may be materially harmed. 

In order to develop our product candidates, apply for regulatory approvals and commercialize our product candidates, we will need to develop, contract for, 
or otherwise arrange for the necessary manufacturing capabilities. In September 2016, we entered into a lease for a multi-use facility of approximately 
90,000 square feet in Lexington, Massachusetts to provide internal cGMP manufacturing capabilities and increase control and visibility of our drug 
substance supply chain, and we began cGMP manufacturing in this facility at the beginning of 2018. This facility supplements our existing Cambridge, 
Massachusetts laboratory and office space headquarters, enhances our ability to secure drug substance for current and future development activities and 
may provide commercial-scale manufacturing capabilities. However, while we have established and continue to enhance our internal cGMP manufacturing 
capabilities, we have limited experience manufacturing drug substance on a commercial scale, and we will incur significant costs to develop this expertise 
internally. 

In addition to the oligonucleotides that we manufacture internally, we may utilize CMOs to manufacture the oligonucleotides required for our preclinical 
studies and clinical trials. There are a limited number of manufacturers that supply oligonucleotides. There are risks inherent in pharmaceutical 
manufacturing that could affect our ability or the ability of our CMOs to meet our delivery time requirements or provide adequate amounts of material to 
meet our clinical trial demands on our projected timelines. Included in these risks are potential synthesis and purification failures and/or contamination 
during the manufacturing process, as well as other issues with our facility or the CMOs’ facilities and ability to comply with the applicable manufacturing 
requirements and quality standards, which could result in unusable product and cause delays in our manufacturing timelines and ultimately delay our 
clinical trials, as well as result in additional expense to us. To manufacture our oligonucleotides, we rely on third parties to supply the required raw 
materials. We will likely need to secure alternative suppliers for these raw materials, and such alternative suppliers are limited and may not be readily 
available, or we may be unable to enter into agreements with them on reasonable terms and in a timely manner. For example, we source certain materials 
used in the manufacture of our products from China and other countries outside of the United States; the coronavirus outbreak or other similar global 
disruptions has made access to our existing supply chain difficult and further supply chain disruptions could impact our business. Additionally, our cost of 
goods development is at an early stage. The actual cost to manufacture and process our product candidates could be greater than we expect and could 
materially and adversely affect the commercial viability of our product candidates.

The process of manufacturing oligonucleotides is complex and we may encounter difficulties in production, particularly with respect to process 
development or scaling-up of our manufacturing capabilities. 

The process of manufacturing oligonucleotides is complex, highly-regulated and subject to multiple risks. The complex processes associated with the 
manufacture of our product candidates expose us to various manufacturing challenges and risks, which may include delays in manufacturing adequate 
supply of our product candidates, limits on our ability to increase manufacturing capacity, and the potential for product failure and product variation in 
quality that may interfere with preclinical studies and clinical trials, along with additional costs. We also may make changes to our manufacturing process 
at various points during development, and even after commercialization, for various reasons, such as optimizing costs, achieving scale, decreasing 
processing time, increasing 

66

 
 
manufacturing success rate, or other reasons. Such changes carry the risk that they will not achieve their intended objectives, and any of these changes 
could cause our product candidates to perform differently and affect the results of current or future clinical trials, or the performance of the product, once 
commercialized. In some circumstances, changes in the manufacturing process may require us to perform ex vivo comparability studies, and/or conduct 
animal studies, and to collect additional data from patients prior to undertaking more advanced clinical trials. For instance, changes in our process during 
the course of clinical development may require us to show the comparability of the product used in earlier clinical trials or at earlier portions of a trial to the 
product used in later clinical trials or later portions of the trial. We may also make further changes to our manufacturing process before or after 
commercialization, and such changes may require us to show the comparability of the resulting product to the product produced via earlier manufacturing 
processes and supplied in clinical studies. We may be required to collect additional preclinical and/or clinical data from any modified process prior to 
obtaining marketing approval for the product candidate produced with such modified process. If preclinical and/or clinical data are not ultimately 
comparable to those seen in the earlier trials, we may be required to make further changes to our process and/or undertake additional clinical testing, either 
of which could significantly delay the clinical development or commercialization of the associated product candidate. 

We have a robust and diverse pipeline of PN-modified, stereopure oligonucleotides, including programs using our editing, splicing, and silencing 
modalities. Our lead clinical programs are focused in, and aim to address, muscle diseases (DMD – splicing), hepatic diseases (AATD – editing), and CNS 
diseases (HD, ALS and FTD – silencing). Although we continue to build on our experience in manufacturing oligonucleotides, we have limited experience 
as a company manufacturing product candidates for commercial supply. We may never be successful in manufacturing product candidates in sufficient 
quantities or with sufficient quality for commercial use. Our manufacturing capabilities could be affected by cost-overruns, unexpected delays, equipment 
failures, labor shortages, operator error, natural disasters, unavailability of qualified personnel, difficulties with logistics and shipping, problems regarding 
yields or stability of product, contamination or other quality control issues, power failures, and numerous other factors that could prevent us from realizing 
the intended benefits of our manufacturing strategy and have a material adverse effect on our business. 

Furthermore, compliance with cGMP requirements and other quality issues may arise during our internal efforts to scale-up manufacturing, and with our 
current or any future CMOs. If contaminants are discovered in our supply of our product candidates or in our manufacturing facilities or those of our 
CMOs, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination. We cannot assure 
you that any stability failures or other issues relating to the manufacture of our product candidates will not occur in the future. Additionally, we and our 
CMOs may experience manufacturing difficulties due to resource constraints or as a result of labor disputes or unstable political environments. If we or our 
CMOs were to encounter any of these difficulties, our ability to provide our product candidate to patients in clinical trials, or to provide product for 
treatment of patients once approved, would be jeopardized.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications 
that may be more profitable or for which there is a greater likelihood of success. 

Because we have limited financial resources, we intend to focus on developing product candidates for specific indications that we identify as most likely to 
succeed, in terms of both regulatory approval and commercialization. As a result, we may forego or delay pursuit of opportunities with other product 
candidates or for other indications that may prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize 
on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product 
candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target 
market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty 
arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product 
candidate. 

Any product candidates we develop may fail in preclinical or clinical development or be delayed to a point where they do not become commercially 
viable.

Before obtaining regulatory approval for the commercial distribution of any of our product candidates, we must conduct, at our own expense, extensive 
preclinical studies and clinical trials to demonstrate the safety and efficacy in humans of our product candidates. Preclinical and clinical testing are 
expensive, difficult to design and implement, can take many years to complete, are uncertain as to outcome, and the historical failure rate for drugs in 
preclinical and clinical development is high. For example, we depend on the availability of non-human primates to conduct certain preclinical studies. Over 
the past several years there has been an increasing global shortage of non-human primates available for drug development that has matured into an acute 
global supply chain issue. The supply of these non-human primates is currently constrained due to factors such as their limited worldwide availability, 
domestic regulatory restrictions and trade relations. If we are unable to obtain access to a sufficient supply of these non-human primates in a timely manner 
or at all, our timelines and our ability to complete preclinical testing and submit CTA applications may be adversely affected.

67

 
We, the FDA or comparable foreign regulatory authorities or an IRB, or similar foreign review board or ethics committee, may suspend clinical trials of a 
product candidate at any time for various reasons, including if we or they believe the healthy volunteer subjects or patients participating in such trials are 
being exposed to unacceptable health risks. Among other reasons, unacceptable side effects or other more serious adverse events of a product candidate in 
healthy volunteer subjects or patients in a clinical trial could result in the FDA or comparable foreign regulatory authorities suspending or terminating the 
trial and refusing to approve a particular product candidate for any or all indications of use. 

Clinical trials also require the review, oversight and approval of IRBs or ethics committees, which review the clinical protocols and informed consent form 
for investigations that will be conducted at their institutions in order to protect the rights and welfare of human subjects. Inability to obtain or delay in 
obtaining IRB approval can prevent or delay the initiation and completion of clinical trials at particular sites. Furthermore, failure to provide information to 
the IRB and relevant regulatory authorities, as required throughout the study, such as emergent safety reports and annual updates, may result in suspension 
of the approval of the trial. Our product candidates may encounter problems during clinical trials that will cause us or regulatory authorities to delay, 
suspend or terminate these trials, or that will delay or confound the analysis of data from these trials. If we experience any such problems, we may not have 
the financial resources to continue development of the product candidate that is affected or any of our other product candidates. We may also lose, or be 
unable to enter into, collaborative arrangements for the affected product candidate and for other product candidates we are developing. The development of 
one or more of our product candidates can fail at any stage of testing. We may experience numerous unforeseen events during, or as a result of, preclinical 
studies and clinical trials that could delay or prevent regulatory approval or our ability to commercialize our product candidates, including: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

our preclinical studies or clinical trials may produce negative or inconclusive results, including results that may not meet the level of significance or 
clinical benefit required by the FDA or other regulators, and we may decide, or regulators may require us, to conduct additional preclinical studies or 
clinical trials, or we may abandon projects that we had expected to be promising; 

delays in filing clinical trial applications or comparable foreign applications or delays or failure in obtaining the necessary approvals from regulators 
or IRBs in order to commence a clinical trial at a prospective trial site, or their suspension or termination of a clinical trial once commenced; 

conditions imposed on us by the FDA or comparable foreign authorities regarding the scope or design of our clinical trials; 

divergent views between FDA and other homologue regulatory authorities as to the objectives and/or design of the clinical trials required in support 
of marketing registration;

problems in obtaining or maintaining IRB approval of trials; 

delays in enrolling patients or volunteers into clinical trials, and variability in the number and types of patients eligible for clinical trials; 

delays in developing and receiving regulatory approval for companion diagnostic tests, to the extent such tests are needed, to identify patients for our 
clinical trials;

high drop-out rates for patients in clinical trials and substantial missing data; 

an inability to open study sites, or enroll, treat, and monitor patients due to local restrictions implemented in response to COVID-19 (emerging or 
future variants of COVID-19) or other global health pandemics;

negative or inconclusive results from our clinical trials or the clinical trials of others for product candidates similar to ours; 

results from future clinical trials may not confirm positive results, if any, from earlier preclinical studies and clinical trials; 

inability to consistently manufacture, inadequate supply, or unacceptable quality of product candidate materials or other materials necessary for the 
conduct of our clinical trials; 

greater than anticipated clinical trial costs; 

serious and unexpected side effects that may or may not be related to the product candidate being tested that are experienced by participants in our 
clinical trials or by individuals using drugs similar to our product candidates; 

poor or disappointing effectiveness of our product candidates during clinical trials; 

unfavorable outcome of FDA or other regulatory agency inspection and review of a manufacturing or clinical trial site or other records relating to the 
clinical investigation; 

failure of our third-party contractors, investigators, or collaboration partners to comply with regulatory requirements or otherwise meet their 
contractual obligations in a timely manner, or at all; 

68

 
•

•

governmental or regulatory delays and changes in regulatory requirements, policy and guidelines, including the imposition of additional regulatory 
oversight around manufacturing, preclinical, or clinical testing generally or with respect to our product candidates class, in particular; or 

varying interpretations of data by the FDA and similar foreign regulatory agencies. 

If we do not successfully conduct clinical development, we will not be able to market and sell products derived from our product candidates and to generate 
product revenues. Even if we do successfully complete clinical trials, those results are not necessarily predictive of results of additional trials that may be 
needed before we can submit an application for regulatory approval to the FDA or foreign regulatory agencies. If the development of any of our product 
candidates fails or is delayed to a point where such product candidate is no longer commercially viable, our business may be materially harmed.

Results of preclinical studies and early clinical trials may not be predictive of results of future clinical trials. 

The results from preclinical studies or early clinical trials of a product candidate may not predict the results that will be obtained in subsequent subjects or 
in subsequent clinical trials of that product candidate or any other product candidate. The design of a clinical trial can determine whether its results will 
support approval of a product candidate and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. In 
addition, preclinical and clinical data are often susceptible to varying interpretations and analyses. Product candidates that seemingly perform satisfactorily 
in preclinical studies may nonetheless fail to reach late development stages or obtain regulatory approval for marketing. For example, our preclinical 
studies for suvodirsen yielded positive results. However, in December 2019, the interim analysis of the Phase 1 open-label extension (OLE) study of 
suvodirsen for patients with DMD showed no change from baseline in dystrophin expression and resulted in our discontinuation of the suvodirsen program. 
There is a high failure rate for drugs proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have 
suffered significant setbacks in clinical development even after achieving promising results in earlier studies, and any such setbacks in our clinical 
development could negatively affect our business and operating results. 

If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary regulatory approvals could be delayed or 
prevented. 

Clinical trials of a new product candidate require the enrollment of a sufficient number of patients, including patients who are suffering from the disease the 
product candidate is intended to treat and who meet other eligibility criteria. Rates of patient enrollment are affected by many factors, including the 
COVID-19 global pandemic or emerging or future variants of COVID-19, the size of the patient population, the age and condition of the patients, the stage 
and severity of disease, the nature and requirements of the protocol, the proximity of patients to clinical sites, the availability of effective treatments for the 
relevant disease, and the eligibility criteria for the clinical trial. Delays or difficulties in patient enrollment or difficulties retaining trial participants, 
including as a result of the availability of existing or other investigational treatments, can result in increased costs, longer development times or termination 
of a clinical trial. 

In addition, our success may depend, in part, on our ability to identify patients who qualify for our clinical trials, or are likely to benefit from any medicines 
that we may develop, which will require those potential patients to undergo a screening assay, which we also refer to as a companion diagnostic test, for the 
presence or absence of a particular genetic sequence. For example, in HD, we are conducting a clinical trial for WVE-003, which targets a SNP associated 
with the mutant allele of the HTT gene. Approximately 40% of the HD patient population carry this SNP. We have developed a novel screening assay that 
is intended to identify whether a patient has the particular SNP that our product candidate is targeting, and partnered with a third party for testing in future 
trials. If we, or any third parties that we engage to assist us are unable to successfully identify patients with the appropriate SNP that we are targeting, the 
percentage of patients with the SNP we are targeting is lower than expected, or we experience delays in testing, we may not realize the full commercial 
potential of any product candidates we develop. 

If we are unable to successfully develop or obtain regulatory approval for companion diagnostic tests for our product candidates, or experience 
significant delays in doing so, our clinical trials may be delayed and our business could be materially harmed.

The development programs for some of our product candidates contemplate the development of companion diagnostic tests, which are assays or tests to 
identify an appropriate patient population. The success of certain of our product candidates will depend on several factors, including the successful 
development of, and ability to obtain regulatory approval for, companion diagnostic tests that will be used to screen and identify the right patients for our 
product candidates. Our goal is to develop and commercialize disease-modifying medicines for genetically defined diseases with a high degree of unmet 
medical need, and to become a fully integrated genetic medicines company. The target patient populations for several of our product candidates are 
relatively small, and it will be difficult to successfully identify the appropriate patients for whom our product candidates are being designed without 
performant, fit-for-purpose, accessible, relatively inexpensive, and easy-to-use companion diagnostic tests. 

69

 
Companion diagnostic tests are subject to regulation by the FDA and similar regulatory authorities outside the United States as medical devices, often in 
vitro devices, and require separate regulatory authorization prior to commercialization. We are not a medical device company, and we have limited 
experience developing medical devices. A more detailed description of the FDA approval process for companion diagnostic tests is included under 
“Business – Government Regulation – In Vitro Diagnostic Tests for Biomarkers.” Given our limited experience in developing and commercializing 
companion diagnostic tests, we may seek to collaborate with third parties to assist us in the design, manufacture, regulatory authorization and 
commercialization of the companion diagnostic tests for some of our product candidates. In November 2019, we entered into a collaboration with 
Asuragen, Inc. (“Asuragen”) for the development and commercialization of companion diagnostics for our allele-selective product candidate in HD. We, 
Asuragen and other potential collaborators may encounter difficulties in developing and obtaining approval for the companion diagnostic tests, including 
issues relating to sensitivity/specificity, analytical validation, reproducibility, or clinical validation. Any delay or failure by us or our collaborators to 
develop or obtain regulatory authorization of the relevant companion diagnostic tests could delay or prevent approval of our product candidates. If we, 
Asuragen or any other third parties that we engage to assist us, are unable to successfully develop, validate, and commercialize companion diagnostic tests 
for our drug candidates, or experience delays in doing so, our clinical trials and our business could be materially harmed.

We may be unable to obtain regulatory approval in the United States or foreign jurisdictions and, as a result, be unable to commercialize our product 
candidates and our ability to generate revenue will be materially impaired. 

Our product candidates are subject to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, 
quality, safety, efficacy, approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing and distribution of 
drugs. Rigorous preclinical studies and clinical trials, and an extensive regulatory approval process are required to be successfully completed in the United 
States and in many foreign jurisdictions before a new drug can be marketed. Satisfaction of these and other regulatory requirements is costly, time 
consuming, uncertain, and subject to a continuously evolving regulatory environment and unanticipated delays. It is possible that none of the product 
candidates we may develop will obtain the regulatory approvals necessary for us or our collaborators to begin selling them. 

The time required to obtain FDA and other approvals is unpredictable but typically takes many years following the commencement of clinical trials, 
depending upon the type, complexity and novelty of the product candidate. The standards that the FDA and its foreign counterparts use when regulating 
companies such as ours are not always applied predictably or uniformly and can change. Any analysis we perform of data from chemistry, manufacturing 
and controls, preclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent 
regulatory approval. We may also encounter unexpected delays or increased costs due to new government regulations, for example, from future legislation 
or administrative action, or from changes in FDA policy during the period of product development, clinical trials and FDA regulatory review. It is 
impossible to predict whether legislative changes will be enacted, or whether FDA or foreign regulations, guidance or interpretations will be changed, or 
what the impact of such changes, if any, may be.

Any delay or failure in obtaining required approvals could adversely affect our ability to generate revenues from the particular product candidate for which 
we are seeking approval. Furthermore, any regulatory approval to market a product may be subject to limitations on the approved uses for which we may 
market the product or the labeling or other restrictions. In addition, the FDA has the authority to require a Risk Evaluation and Mitigation Strategy 
(“REMS”), as a condition of approval, which may impose further requirements or restrictions on the distribution or safe use of an approved drug, such as 
limiting prescribing rights to certain physicians or medical centers that have undergone specialized training, limiting treatment to patients as specially 
defined by the indication statement or who meet certain safe-use criteria, and requiring treated patients to enroll in a registry, among other requirements. 
These limitations and restrictions may limit the size of the market for the product and affect reimbursement by third-party payors. 

We are also subject to numerous foreign regulatory requirements governing, among other things, the conduct of clinical trials, manufacturing and 
marketing authorization, pricing and payment. The foreign regulatory approval process varies among countries and may include all of the risks associated 
with FDA approval described above, as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Approval by the FDA does 
not ensure approval by comparable regulatory authorities outside of the United States and vice versa. 

If we are granted orphan drug designations in the United States for any of our product candidates, there can be no guarantee that we will maintain 
orphan status for these product candidates or receive approval for any product candidate with an orphan drug designation.

Subject to receiving approval from the FDA of an NDA or Biologics License Application (“BLA”), products granted orphan drug designation are provided 
with seven years of orphan marketing exclusivity in the United States, meaning the FDA generally will not approve applications for other product 
candidates for the same orphan indication that contain the same active ingredient.

We are not guaranteed to maintain or receive orphan designation for our current or future product candidates, and if our product candidates that were 
granted orphan designation were to lose their status as an orphan drug or the orphan marketing exclusivity provided to it in the United States, our business 
and results of operations could be materially adversely affected. While orphan status for any of our products, if granted or maintained, would provide 
market exclusivity in the United States for the time periods specified above, we would not be able to exclude other companies from manufacturing and/or 
selling products using the same active ingredient for the same indication beyond the exclusivity period applicable to our product on the sole basis of orphan 
drug status. In addition, orphan exclusivity does not block the approval of a different drug or biologic for the same rare disease or condition, nor does it 
block the approval of the same drug or biologic for different conditions. Even if we are the first to obtain approval of an orphan product candidate and are 
granted exclusivity in the United States, there are circumstances under which a later competitor product may be approved for the same indication during the 
period of marketing exclusivity, such as if the later product is shown to be clinically superior to our product or if we are not able to provide a sufficient 
quantity of the orphan drug. 

Even if we obtain regulatory approvals, our marketed drugs will be subject to ongoing regulatory oversight. If we fail to comply with continuing U.S. 
and foreign requirements, our approvals, if obtained, could be limited or withdrawn, we could be subject to other penalties, and our business would be 
seriously harmed. 

Following any initial regulatory approval of any drugs we may develop, we will also be subject to continuing regulatory oversight, including the review of 
adverse drug experiences and safety data that are reported after our drug products are made commercially available. This would include results from any 
post-marketing studies or surveillance to monitor the safety and efficacy of the drug product required as a condition of approval or agreed to by us. Any 
regulatory approvals that we receive for our product candidates may also be subject to limitations on the approved uses for which the product may be 
marketed. Other ongoing regulatory requirements include, among other things, submissions of safety and other post-marketing information and reports, 
registration and listing, as well as continued maintenance of our marketing application, compliance with cGMP requirements and quality oversight, 
compliance with post-marketing commitments, and compliance with GCP for any clinical trials that we conduct post-approval. Failure to comply with 
these requirements could result in warning or untitled letters, criminal or civil penalties, recalls, or product withdrawals. In addition, we are conducting our 
clinical trials and we intend to seek approval to market our product candidates in jurisdictions outside of the United States, and therefore will be subject to, 
and must comply with, regulatory requirements in those jurisdictions. 

The FDA has significant post-market authority, including, for example, the authority to require labeling changes based on new safety information and to 
require post-market studies or clinical trials for a variety of reasons. The FDA also has the authority to require a REMS plan after approval, which may 
impose further requirements or restrictions on the distribution or use of an approved drug. 

We, our CMOs, and the manufacturing facilities we use to make our product candidates will also be subject to ongoing assessment of product quality, 
compliance with cGMP, and periodic inspection by the FDA and potentially other regulatory agencies. We or our CMOs may not be able to comply with 
applicable cGMP regulations or similar regulatory requirements outside of the United States. Our failure, or the failure of our CMOs, to comply with 
applicable regulations could result in regulatory actions, such as the issuance of FDA Form 483 notices of observations, warning letters or sanctions being 
imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or 
recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of 
our products. We may not have the ability or capacity to manufacture material at a broader commercial scale in the future. We and our CMOs currently 
manufacture a limited supply of clinical trial materials. Reliance on CMOs entails risks to which we would not be subject if we manufactured all of our 
material ourselves, including reliance on the CMO for regulatory compliance. Our product promotion and advertising will also be subject to regulatory 
requirements and continuing regulatory review. 

If we or our collaborators, manufacturers or service providers fail to comply with applicable continuing regulatory requirements in the United States or 
foreign jurisdictions in which we may seek to market our products, we or they may be subject to, among other things, fines, warning letters, holds on 
clinical trials, refusal by the FDA or comparable foreign regulatory authorities to approve pending applications or supplements to approved applications, 
suspension or withdrawal of regulatory approval, product recalls and seizures, refusal to permit the import or export of products, operating restrictions, 
injunction, consent decree, civil penalties and criminal prosecution. 

Even if we receive regulatory approval to market our product candidates, the market may not be receptive to our product candidates upon their 
commercial introduction, which will prevent us from becoming profitable. 

Our product candidates are based upon new discoveries, technologies and therapeutic approaches. Key participants in pharmaceutical marketplaces, such as 
physicians, third-party payors and consumers, may not adopt a product intended to improve therapeutic results that is based on the technology employed by 
oligonucleotides. As a result, it may be more difficult for us to convince the medical community and third-party payors to accept and use our product, or to 
provide favorable reimbursement. 

71

 
Other factors that we believe will materially affect market acceptance of our product candidates include: 

•

•

•

•

•

•

•

•

•

•

the timing of our receipt of any regulatory approvals, the terms of any approvals and the countries in which approvals are obtained; 

the ability to consistently manufacture our products within acceptable quality standards;

the safety and efficacy of our product candidates, as demonstrated in clinical trials and as compared with alternative treatments, if any; 

the incidence, seriousness and severity of any side effects; 

the relative convenience and ease of administration of our product candidates; 

the willingness of patients to accept potentially new routes of administration and their risk tolerance as it relates to potentially serious 
side effects; 

the success of our physician education programs; 

the availability of government and third-party payer coverage and adequate reimbursement; 

the pricing of our products, particularly as compared to alternative treatments; and 

the availability of alternative effective treatments for the diseases that product candidates we develop are intended to treat and the 
relative risks, benefits and costs of those treatments. 

In addition, our estimates regarding the potential market size may be materially different from what we currently expect at the time we commence 
commercialization, which could result in significant changes in our business plan and may significantly harm our results of operations and financial 
condition. 

The pharmaceutical industry is intensely competitive. If we are unable to compete effectively with existing drugs, new treatment methods and new 
technologies, we may be unable to commercialize successfully any drugs that we develop. 

The pharmaceutical industry is intensely competitive and rapidly changing. Many large pharmaceutical and biotechnology companies, academic 
institutions, governmental agencies and other public and private research organizations are pursuing the development of novel drugs for the same diseases 
that we are targeting or expect to target. Many of our competitors have: 

•

•

•

•

•

much greater financial, technical and human resources than we have at every stage of the discovery, development, manufacture and 
commercialization of products; 

more extensive experience in designing and conducting preclinical studies and clinical trials, obtaining regulatory approvals, and 
manufacturing, marketing and selling pharmaceutical products; 

product candidates that are based on previously tested or accepted technologies; 

products that have been approved or are in late stages of development; and 

collaborative arrangements in our target markets with leading companies and research institutions. 

We will face intense competition from drugs that have already been approved and accepted by the medical community for the treatment of the conditions 
for which we may develop drugs. We also expect to face competition from new drugs that enter the market. We believe a significant number of drugs are 
currently under development, and may become commercially available in the future, for the treatment of conditions that our current or future product 
candidates are or may be designed to treat. These drugs may be more effective, safer, less expensive, or marketed and sold more effectively, than any 
products we develop. 

Our competitors may develop or commercialize products with significant advantages over any products we are able to develop and commercialize based on 
many different factors, including: 

•

•

•

•

the safety and effectiveness of our products relative to alternative therapies, if any; 

the ease with which our products can be administered and the extent to which patients accept relatively new routes of administration; 

the timing and scope of regulatory approvals for these products; 

the availability and cost of manufacturing, marketing and sales capabilities; 

72

 
•

•

•

price; 

more extensive coverage and higher levels of reimbursement; and 

patent position. 

Our competitors may therefore be more successful in commercializing their products than we are, which could adversely affect our competitive position 
and business. Competitive products may make any products we develop obsolete or noncompetitive before we can recover the expenses of developing and 
commercializing our product candidates. Such competitors could also recruit our employees, which could negatively impact our level of expertise and our 
ability to execute on our business plan. 

If we or our collaborators, manufacturers, service providers or other third parties fail to comply with applicable healthcare laws and regulations, we or 
they could be subject to enforcement actions, which could affect our ability to develop, market and sell our products and may harm our reputation. 

We are currently, or may in the future, be subject to federal, state, local, and comparable foreign healthcare laws and regulations relating to areas such as 
fraud and abuse and patients’ rights. These laws may constrain the business or financial arrangements and relationships through which we conduct our 
operations, including how we research, market, sell and distribute our products for which we obtain marketing approval. These laws and regulations 
include: 

•

•

•

•

•

•

the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly and willfully 
soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, 
either the referral of an individual for a healthcare item or service, or the purchasing, recommending, or ordering of an item or service, 
for which payment may be made under a federal healthcare program such as Medicare or Medicaid; 

the U.S. federal false claims and civil monetary penalties laws, including the False Claims Act, which prohibits, among other things, 
individuals or entities from knowingly presenting or causing to be presented, claims for payment by government-funded programs such 
as Medicare or Medicaid that are false or fraudulent, or making a false statement to avoid, decrease, or conceal an obligation to pay 
money to the federal government; 

the U.S. federal Health Insurance Portability and Accountability Act (“HIPAA”), which, among other things, criminalizes a wide array 
of conduct involving public and private healthcare benefits, creates new civil enforcement mechanisms and increases civil and criminal 
penalties for healthcare fraud; 

HIPAA as amended by the Health Information Technology for Economic and Clinical Health (“HITECH”) Act, and its implementing 
regulations, which strengthen and expand requirements relating to the privacy, security, and transmission of individually identifiable 
health information; and require notification to affected individuals and regulatory authorities of certain breaches of security of 
individually identifiable health information; 

the U.S. federal Physician Payments Sunshine Act, which requires certain manufacturers of medical devices, biological products, 
medical supplies, and drugs for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with 
specific exceptions, to report annually to the Centers for Medicare and Medicaid Services (“CMS”) all transfers of value, including 
consulting fees, travel reimbursements, research grants, and other payments or gifts with values over $10 made to physicians, certain 
advanced non-physician health care practitioners, or teaching hospitals and requires applicable manufacturers and applicable group 
purchasing organizations to report annually to CMS ownership and investment interests held by physicians and their immediate family 
members. Disclosure of such information is made by CMS on a publicly available website; and 

state and foreign laws comparable to each of the above federal laws, such as, for example: state anti-kickback and false claims laws 
applicable to commercial insurers and other non-federal payors; state laws that require pharmaceutical manufacturers to comply with the 
pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal 
government; state laws that require drug manufacturers to report information related to payments and other transfers of value to 
physicians and other healthcare providers or marketing expenditures; and state and foreign laws governing the privacy and security of 
health information, some which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating 
compliance efforts. 

If our operations are found to be in violation of any such requirements, we may be subject to penalties, including civil or criminal penalties, criminal 
prosecution, monetary damages, the curtailment or restructuring of our operations, loss of eligibility to obtain approvals from the FDA, exclusion from 
participation in federal healthcare programs including Medicare and Medicaid, the imposition of a corporate integrity agreement with the Office of 
Inspector General of the Department of Health and Human Services, 

73

 
disgorgement, individual imprisonment, contractual damages, reputational harm, and diminished profits and future earnings, any of which could adversely 
affect our financial results and adversely affect our ability to operate our business. We intend to develop and implement a comprehensive corporate 
compliance program prior to the commercialization of our product candidates. Although effective compliance programs can mitigate the risk of 
investigation and prosecution for violations of these laws, these risks cannot be entirely eliminated. Any action against us for an alleged or suspected 
violation could cause us to incur significant legal expenses, could divert our management’s attention from the operation of our business, and could harm 
our reputation, even if our defense is successful. In addition, achieving and sustaining compliance with applicable laws and regulations may be costly to us 
in terms of money, time and resources. 

If we or our collaborators, manufacturers or service providers fail to comply with applicable federal, state or foreign laws or regulations, we could be 
subject to enforcement actions, which could affect our ability to develop, market and sell our products successfully and could harm our reputation and lead 
to reduced acceptance of our products by the market. These enforcement actions include, among others: 

•

•

•

•

•

•

•

•

•

•

•

•

•

adverse regulatory inspection findings; 

warning and/or untitled letters; 

voluntary or mandatory product recalls or public notification or medical product safety alerts to healthcare professionals; 

restrictions on, or prohibitions against, marketing our products; 

restrictions on, or prohibitions against, importation or exportation of our products; 

suspension of review or refusal to approve pending applications or supplements to approved applications; 

exclusion from participation in government-funded healthcare programs; 

exclusion from eligibility for the award of government contracts for our products; 

suspension or withdrawal of product approvals; 

product seizures; 

injunctions; 

consent decrees; and 

civil and criminal penalties, up to and including criminal prosecution resulting in fines, exclusion from healthcare reimbursement 
programs and imprisonment. 

Moreover, federal, state or foreign laws or regulations are subject to change, and while we, our collaborators, manufacturers and/or service providers 
currently may be compliant, that could change due to changes in interpretation, prevailing industry standards or other reasons. 

Any drugs we develop may become subject to unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives, 
thereby harming our business. 

Because our product candidates represent new approaches to the treatment of genetic-based diseases, we cannot be sure that coverage and reimbursement 
will be available for, or accurately estimate the potential revenue from, our product candidates or assure that coverage and reimbursement will be available 
for any product that we may develop. The regulations that govern marketing approvals, pricing and reimbursement for new drugs vary widely from country 
to country. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after 
marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing 
governmental control even after initial approval is granted. We are monitoring these regulations as several of our programs move into later stages of 
development; however, many of our programs are currently in the earlier stages of development and we will not be able to assess the impact of price 
regulations for a number of years. As a result, we might obtain regulatory approval for a product in a particular country, but then be subject to price 
regulations that could delay our commercial launch of the product and negatively impact any potential revenues we may be able to generate from the sale 
of the product in that country and potentially in other countries due to reference pricing. 

Our ability to commercialize any products successfully will also depend in part on the extent to which coverage and adequate reimbursement/payment for 
these products and related treatments will be available from government health administration authorities, private health insurers and other organizations. 
Even if we succeed in bringing one or more products to the market, these products may 

74

 
not be considered medically necessary and/or cost-effective, and the amount reimbursed for any products may be insufficient to allow us to sell our 
products on a competitive basis. At this time, we are unable to determine their cost effectiveness or the likely level or method of reimbursement for our 
product candidates. Increasingly, third-party payors, such as government and private insurance plans, are requiring that drug companies provide them with 
predetermined discounts from list prices, and are seeking to reduce the prices charged or the amounts paid for pharmaceutical products. If the price we are 
able to charge for any products we develop, or the payments provided for such products, is inadequate in light of our development and other costs, our 
return on investment could be adversely affected. 

We currently expect that any drugs we develop may need to be administered under the supervision of a physician on an outpatient basis. Under currently 
applicable U.S. law, certain drugs that are not usually self-administered (such as most injectable drugs) may be eligible for coverage under the Medicare 
Part B program if: 

•

•

•

they are incident to a physician’s services; 

they are reasonable and necessary for the diagnosis or treatment of the illness or injury for which they are administered according to 
accepted standards of medical practice; and 

they have been approved by the FDA and meet other requirements of the statute. 

There may be significant delays in obtaining coverage for newly-approved drugs, and coverage may be more limited than the indications for which the drug 
is approved by the FDA or comparable foreign regulatory authorities. Patients who are prescribed medications for the treatment of their conditions, and 
their prescribing physicians, generally rely on third-party payors to pay all or part of the costs associated with their prescription drugs. Patients are unlikely 
to use our products unless coverage is provided and payment is adequate to cover all or a significant portion of the cost of our products. Therefore, 
coverage and adequate payment is critical to new product acceptance. Coverage decisions may depend upon clinical and economic standards that disfavor 
new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Moreover, 
eligibility for coverage does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, 
manufacture, sale and distribution. Interim payments for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made 
permanent. Reimbursement may be based on payments allowed for lower-cost drugs that are already reimbursed, may be incorporated into existing 
payments for other services and may reflect budgetary constraints or imperfections in Medicare data. Net prices for drugs may be reduced by mandatory 
discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of 
drugs from countries where they may be sold at lower prices than in the United States. Third-party payors often rely upon Medicare coverage policy and 
payment limitations in setting their own reimbursement rates. However, no uniform policy requirement for coverage and reimbursement for drug products 
exists among third-party payors in the United States. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. 
As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support 
for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained 
in the first instance. Our inability to promptly obtain coverage and adequate reimbursement rates from both government-funded and private payors for new 
drugs that we develop and for which we obtain regulatory approval could adversely affect our operating results, our ability to raise capital needed to 
commercialize products, and our overall financial condition. 

We believe that the efforts of governments and third-party payors to contain or reduce the cost of healthcare and legislative and regulatory proposals to 
broaden the availability of healthcare will continue to affect the business and financial condition of pharmaceutical and biopharmaceutical companies. A 
number of legislative and regulatory changes in the healthcare system in the United States and other major healthcare markets have been proposed and/or 
adopted in recent years, and such efforts have expanded substantially in recent years. These developments have included prescription drug benefit 
legislation that was enacted in 2003 and took effect in January 2006, healthcare reform legislation enacted by certain states, and major healthcare reform 
legislation that was passed by Congress and enacted into law in the United States in 2010. These developments could, directly or indirectly, affect our 
ability to sell our products, if approved, at a favorable price. 

In particular, in March 2010, the Patient Protection and Affordable Care Act (the “ACA”) was signed into law. This legislation changed the system of 
healthcare insurance and benefits and was intended to broaden access to healthcare coverage, enhance remedies against fraud and abuse, add transparency 
requirements for the healthcare and health insurance industries, impose taxes and fees on the healthcare industry, impose health policy reforms, and control 
costs. This law also contains provisions that would affect companies in the pharmaceutical industry and other healthcare related industries by imposing 
additional costs and changes to business practices. Since its enactment, there have been judicial and Congressional challenges to certain aspects of the 
ACA. The uncertainty around the future of the ACA, and in particular the impact to reimbursement levels, may lead to uncertainty or delay in the 
purchasing decisions of our customers, which may in turn negatively impact our product sales. We continue to evaluate the effect that the ACA has or any 
potential changes to the ACA could have on our business. Additional federal and state legislative and regulatory developments are 

75

 
likely, and we expect ongoing initiatives in the United States to increase pressure on drug pricing and reimbursement. Such reforms could have an adverse 
effect on anticipated revenues from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect 
our overall financial condition and ability to develop product candidates. 

Changes in laws and regulations affecting the healthcare industry could adversely affect our business.

All aspects of our business, including research and development, manufacturing, marketing, pricing, sales, litigation, and intellectual property rights, are 
subject to extensive legislation and regulation. Changes in applicable U.S. federal and state laws and agency regulation, as well as foreign laws and 
regulations, could have a materially negative impact on our business. In the United States and in some other jurisdictions, there have been a number of 
legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of our product 
candidates or any potential future product candidates of ours, restrict or regulate post-approval activities, or affect our ability to profitably sell any product 
candidates for which we obtain marketing approval. Increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or 
prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements. Congress also must 
reauthorize the FDA’s user fee programs every five years and often makes changes to those programs in addition to policy or procedural changes that may 
be negotiated between the FDA and industry stakeholders as part of this periodic reauthorization process. Congress most recently reauthorized the user fee 
programs in September 2022 without any substantive policy changes.

Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in health care systems with the 
stated goals of containing health care costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a focus 
of these efforts and has been significantly affected by major legislative initiatives. In March 2010, Congress passed the ACA, which substantially changed 
the way health care is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical industry. 

There remain judicial and Congressional challenges to certain aspects of the ACA, and as a result certain sections of the ACA have not been fully 
implemented or effectively repealed. However, following several years of litigation in the federal courts, in June 2021, the U.S. Supreme Court upheld the 
ACA when it dismissed a legal challenge to the law’s constitutionality. Further legislative and regulatory changes under the ACA remain possible, although 
the new federal administration under President Biden has signaled that it plans to build on the ACA and expand the number of people who are eligible for 
health insurance subsidies under it. It is unknown what form any such changes or any law would take, and how or whether it may affect the pharmaceutical 
industry as a whole or our business in the future. We expect that changes or additions to the ACA, the Medicare and Medicaid programs, and changes 
stemming from other healthcare reform measures, especially with regard to healthcare access, financing or other legislation in individual states, could have 
a material adverse effect on the healthcare industry in the United States.

The uncertainty around the future of the ACA, and in particular the impact to reimbursement levels, may lead to uncertainty or delay in the purchasing 
decisions of our customers, which may in turn negatively impact our product sales. If there are not adequate reimbursement levels, our business and results 
of operations could be adversely affected. 

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to 
Medicare payments to providers of up to 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013 and was extended by the 
Consolidated Appropriations Act for 2023, and will remain in effect through 2032 unless additional Congressional action is taken. 

In addition, the Drug Supply Chain Security Act enacted in 2013 imposed obligations on manufacturers of pharmaceutical products related to product 
tracking and tracing, and in February 2022, FDA released proposed regulations to amend the national standards for licensing of wholesale drug distributors 
by the states; establish new minimum standards for state licensing third-party logistics providers; and create a federal system for licensure for use in the 
absence of a State program, each of which is mandated by the DSCSA. As another example, in December 2019, the Further Consolidated Appropriations 
Act for 2020 (P.L. 116-94) was enacted that includes a piece of bipartisan legislation called the CREATES Act. The CREATES Act aims to address the 
concern articulated by both the FDA and others in the industry that some brand manufacturers have improperly restricted the distribution of their products, 
including by invoking the existence of a REMS for certain products, to deny generic and biosimilar product developers access to samples of brand 
products. The CREATES Act establishes a private cause of action that permits a generic or biosimilar product developer to sue the brand manufacturer to 
compel it to furnish the necessary samples on “commercially reasonable, market-based terms.” Whether and how generic and biosimilar product 
developments will use this new pathway, as well as the likely outcome of any legal challenges to provisions of the CREATES Act, remain highly uncertain 
and its potential effects on our future commercial products are unknown. Other legislative and regulatory proposals have been made to expand post-
approval requirements and restrict 

76

 
sales and promotional activities for pharmaceutical products. We are unsure whether additional legislative changes will be enacted, or whether the current 
regulations, guidance or interpretations will be changed, or whether such changes will have any impact on our business.

Additionally, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices considering the rising cost of 
prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation 
designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, 
and reform government program reimbursement methodologies for products. For example, state legislatures are increasingly passing legislation and 
implementing regulations designed to control pharmaceutical pricing, including price or patient reimbursement constraints, discounts, restrictions on 
certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other 
countries and bulk purchasing. In December 2020, the U.S. Supreme Court held unanimously that federal law does not preempt the states’ ability to 
regulate pharmaceutical benefit managers (PBMs) and other members of the health care and pharmaceutical supply chain, an important decision that may 
lead to further and more aggressive efforts by states in this area.

At the federal level, DHHS has solicited feedback on various measures intended to lower drug prices and reduce the out of pocket costs of drugs and has 
implemented others under its existing authority. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage plans the option to use 
step therapy for Part B drugs beginning January 1, 2020. This final rule codified CMS’s policy change that was effective January 1, 2019. 

Most recently, in August 2022, President Biden signed into the law the Inflation Reduction Act of 2022 (the “IRA”). Among other things, the IRA has 
multiple provisions that may impact the prices of drug products that are both sold into the Medicare program and throughout the United States. Starting in 
2023, a manufacturer of a drug or biological product covered by Medicare Parts B or D must pay a rebate to the federal government if the product’s price 
increases faster than the rate of inflation. This calculation is made on a drug product by drug product basis and the amount of the rebate owed to the federal 
government is directly dependent on the volume of a drug product that is paid for by Medicare Parts B or D. Additionally, starting in payment year 2026, 
CMS will negotiate drug prices annually for a select number of single source Part D drugs without generic or biosimilar competition. CMS will also 
negotiate drug prices for a select number of Part B drugs starting for payment year 2028. If a drug product is selected by CMS for negotiation, it is 
expected that the revenue generated from such drug will decrease.

Any additional federal or state health care reform measures could limit the amounts that third-party payers will pay for future health care products and 
services, and, in turn, could significantly reduce the projected value of certain development projects and reduce our profitability. 

Risks associated with our operations outside of the United States and developments in international trade by the U.S. and foreign governments could 
adversely affect our business.

We have operations and conduct business outside the United States, and we plan to continue to expand these operations. Therefore, we are subject to risks 
related to operating in foreign countries, which include unfamiliar foreign laws or regulatory requirements or unexpected changes to those laws or 
requirements; other laws and regulatory requirements to which our business activities abroad are subject, such as the Foreign Corrupt Practices Act and the 
U.K. Bribery Act; changes in the political or economic condition of a specific country or region, including Russia’s invasion of Ukraine and the potential 
for a wider European or global conflict; fluctuations in the value of foreign currency versus the U.S. dollar; increasing inflation and interest rate changes, 
our ability to deploy overseas funds in an efficient manner; tariffs, trade protection measures, import or export licensing requirements, trade embargoes, and 
sanctions (including those administered by the Office of Foreign Assets Control of the U.S. Department of the Treasury), and other trade barriers; global 
instability from an outbreak of pandemic or contagious disease, including the COVID-19 global pandemic and variants thereof; difficulties in attracting and 
retaining qualified personnel; and cultural differences in the conduct of business. For example, given developments related to international trade over the 
past few years, unexpected changes in tariffs could adversely affect our cost of goods sold and/or the foreign sales of our product candidates. Further 
complicating potential uncertainties caused by conducting business outside the United States are political movements that are changing decades-old 
institutions, including, for example, in 2016, the United Kingdom held a referendum in which voters approved an exit from the European Union, commonly 
referred to as “Brexit.” The withdrawal of the United Kingdom from the European Union took effect on January 31, 2020, the effective date of the 
withdrawal agreement, with a transition period that ended on December 31, 2020. Since a significant proportion of the regulatory framework in the United 
Kingdom was, prior to Brexit, derived from European Union directives and regulations, Brexit and the new Trade and Cooperation Agreement between the 
European Union and the United Kingdom that took provisional effect on January 1, 2021 could materially impact the regulatory regime with respect to the 
approval of any product candidates in the United Kingdom. Changes impacting our ability to conduct business in the United Kingdom or other European 
Union countries, or 

77

 
changes to the regulatory regime applicable to our operations in those countries (such as with respect to the approval of our product candidates), may 
materially and adversely impact our business, prospects, operating results, and financial condition.

We or third parties upon whom we depend may be adversely affected by natural disasters and/or health epidemics, and our business, financial condition 
and results of operations could be adversely affected. 

Natural disasters could severely disrupt our operations and have a material adverse effect on our business operations. If a natural disaster, health epidemic, 
or other event beyond our control occurred that prevented us from using all or a significant portion of our office, manufacturing and/or lab spaces, that 
damaged critical infrastructure, such as the manufacturing facilities of our third-party contract manufacturers, or that otherwise disrupted operations, it may 
be difficult for us to continue our business for a substantial period of time. Any outbreak of contagious diseases, or other adverse public health 
developments, could have a material and adverse effect on our business operations. For example, during the COVID-19 global pandemic, clinical site 
initiation and patient enrollment in our clinical trials were delayed due to prioritization of hospital resources in favor of COVID-19 patients and difficulties 
in recruiting clinical site investigators and clinical site staff. The COVID-19 global pandemic, including emerging or future variants of COVID-19, and its 
impact on our business is highly uncertain and subject to change. We do not yet know the full extent of potential delays or long-term impacts on our 
business, our preclinical studies and clinical trials, healthcare systems or the global economy. In addition, certain of our research and development efforts 
are conducted globally. A health epidemic or other outbreak could materially and adversely affect our business, financial condition and results of 
operations.

The disaster recovery and business continuity plans we have in place may prove inadequate in the event of a serious disaster or similar event. We may incur 
substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on 
our business.

There is a substantial risk of product liability claims in our business. If we are unable to obtain or maintain sufficient insurance, a product liability 
claim against us could adversely affect our business. 

Our business exposes us to significant potential product liability risks that are inherent in the development, testing, manufacturing and marketing of human 
therapeutic products. Product liability claims could delay or prevent completion of our clinical development programs. In addition, if any of our 
collaboration partners face product liability claims, our programs could also be affected and our business could be harmed. If we succeed in marketing 
products, such claims could result in an FDA investigation of the safety and effectiveness of our products, our manufacturing processes and facilities or our 
marketing programs, and potentially a recall of our products or more serious enforcement action, limitations on the approved indications for which they 
may be used, or suspension or withdrawal of approvals. Regardless of the merits or eventual outcome, liability claims may also result in decreased demand 
for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary 
awards to trial participants or patients and a decline in our share price. Any insurance we obtain may not provide sufficient coverage against potential 
liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, we may be unable to obtain or 
maintain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims that could adversely affect our business. 

If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected. 

Our research, development and manufacturing processes involve the use of hazardous materials. We maintain quantities of various flammable and toxic 
chemicals in our facilities that are required for our research, development and manufacturing activities. We are subject to federal, state and local laws and 
regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. Our procedures for storing, handling and 
disposing of these materials are reviewed against the relevant guidelines and laws of the jurisdictions in which our facilities are located on a regular basis. 
Although we believe that our safety procedures for handling and disposing of these materials sufficiently mitigate the risk of accidental contamination or 
injury from these materials, the risk cannot be completely eliminated. If an accident occurs, we could be held liable for resulting damages, which could be 
substantial. We are also subject to numerous environmental, health and workplace safety laws and regulations, including those governing laboratory 
procedures, exposure to blood-borne pathogens and the handling of biohazardous materials. Although we maintain workers’ compensation insurance to 
cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of these materials, this insurance may not provide 
adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us 
in connection with our storage or disposal of biological or hazardous materials. Additional federal, state and local laws and regulations affecting our 
operations may become applicable in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate any of, these 
laws or regulations.

Risks Related to Our Dependence on Third Parties 

We depend on collaborations with third parties for the development and commercialization of certain of our product candidates. 

We depend on third-party collaborators for the co-development and co-commercialization of certain of our product candidates and we face significant 
competition to the extent we elect to collaborate with others. Our potential future collaborators include large and mid-size pharmaceutical companies, 
regional and national pharmaceutical companies and biotechnology companies. In addition, there have been a significant number of business combinations 
among these companies that have resulted in a reduced number of potential future collaborators. In January 2023, we commenced a collaboration with GSK 
to research, develop, and commercialize oligonucleotide therapeutics, including WVE-006, our preclinical, first-in-class A-to-I(G) RNA editing candidate 
for AATD. In April 2018, we commenced a collaboration with Takeda to discover, develop and commercialize oligonucleotides for disorders of the CNS. 
The collaboration provides Takeda with the option to globally co-develop and commercialize programs targeting HD, ALS, FTD, and SCA3, which we will 
have the right to co-commercialize in the United States. Collaborations are complex and time-consuming to negotiate and document. We may not be able to 
negotiate collaborations on a timely basis, on acceptable terms, or at all. We may also be restricted under existing license or collaboration agreements from 
entering into agreements on certain terms with other potential collaborators. If we are unable to enter into collaborations with respect to a product 
candidate, we may have to curtail the development of such product candidate, reduce or delay its development program or one or more of our other 
development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and 
undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or 
commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do 
not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenue. 

Depending on the type of collaborations we enter into, we may have limited control over the amount and timing of resources that our collaborators dedicate 
to the development or commercialization of our product candidates. Our ability to generate revenues from these arrangements will depend on our 
collaborators’ abilities and efforts to successfully perform the functions assigned to them in these arrangements. 

Collaborations involving our product candidates may pose the following risks to us: 

•

•

•

•

•

•

•

•

•

collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations; 

collaborators may not pursue development and commercialization of our product candidates or may elect not to continue or renew 
development or commercialization programs based on clinical trial results, changes in the collaborator’s strategic focus or available 
funding or external factors such as an acquisition that diverts resources or creates competing priorities; 

collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product 
candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing; 

collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our products 
or product candidates if the collaborators believe that competitive products are more likely to be successfully developed or can be 
commercialized under terms that are more economically attractive than ours; 

collaborators may require us to enter into collaboration agreements that contain exclusivity provisions and/or termination penalties;

a collaborator with marketing and distribution rights to one or more products may not commit sufficient resources to the marketing and 
distribution of such product or products; 

collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way 
as to invite litigation that could jeopardize or invalidate our proprietary information or expose us to potential litigation; 

disputes may arise between the collaborators and us that result in the delay or termination of the research, development or 
commercialization of our products or product candidates or that result in costly litigation or arbitration that diverts management 
attention and resources; and 

collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or 
commercialization of the applicable product candidates. 

79

 
Collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner, or at all. Further, if a 
present or future collaborator of ours were to be involved in a business combination, the continued pursuit and emphasis on our product development or 
commercialization program could be delayed, diminished or terminated. 

We may not be able to execute our business strategy optimally if we are unable to maintain our existing collaborations or enter into new collaborations 
with partners that can provide sales, marketing and distribution capabilities and funds for the development and commercialization of our product 
candidates.

We do not currently have any sales and marketing or distribution capabilities. Accordingly, we entered into collaborations with GSK and Takeda, which we 
believe can assist us in building these capabilities. We may also enter into additional alliances in the future. We have selectively chosen to enter into our 
strategic collaborations because we believe this is the optimal way for us to leverage our resources and create significant value for ourselves and our 
shareholders, as we advance oligonucleotide candidates for genetically defined diseases.

Depending on the collaborations that we enter into, we may expect our collaborators to provide assistance with development, regulatory affairs, marketing, 
sales and distribution, among other areas. Our future revenues may depend heavily on the success of the efforts of these third parties. For example, under 
our collaboration with Takeda, if Takeda exercises its option with respect to any of our programs in HD, ALS, FTD or SCA3, we will rely on Takeda for 
commercialization of such optioned programs outside of the United States. Under our collaboration with GSK, GSK is responsible for later clinical 
development and commercialization of our program in AATD.

We may not be successful in our collaborations due to various factors, including our ability to successfully demonstrate proof of mechanism in humans, our 
ability to demonstrate the safety and efficacy of our specific product candidates, our ability to manufacture or have third parties manufacture our product 
candidates, the strength of our intellectual property and/or concerns about potential challenges to or limitations of our intellectual property. To the extent we 
have entered into, or enter into new, collaborations, we may not be able to maintain them if, for example, development or approval of a product candidate is 
delayed, challenges are raised as to the validity or scope of our intellectual property or sales of an approved drug are lower than we or our collaboration 
partner expected. 

For certain product candidates that we may develop, we have formed collaborations to fund all or part of the costs of drug development and 
commercialization, such as our collaborations with GSK and Takeda. We may not, however, be able to enter into additional collaborations for certain other 
programs, and the terms of any collaboration agreement we do secure may not be favorable to us. If we are not successful in our efforts to enter into future 
collaboration arrangements with respect to one or more of our product candidates, we may not have sufficient funds to develop that or any other product 
candidate internally, or to bring any product candidates to market. If we do not have sufficient funds to develop and bring our product candidates to market, 
we will not be able to generate sales revenues from these product candidates, and this will substantially harm our business.

We rely, and expect to continue to rely, on third parties to conduct some aspects of our compound formulation, research, preclinical studies and clinical 
trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such formulation, research or 
testing. 

We do not independently conduct all aspects of our drug discovery activities, compound formulation research, preclinical studies, or clinical trials of 
product candidates. We currently rely, and expect to continue to rely, on third parties to conduct some aspects of our research and development, preclinical 
and clinical studies. Any of these third parties may terminate their engagements with us at any time. If we need to enter into alternative arrangements, it 
would delay our product development activities. Our reliance on these third parties for research and development activities will reduce our control over 
these activities but will not relieve us of our responsibilities. For example, for product candidates that we develop and commercialize on our own, we will 
remain responsible for ensuring that each of our studies that support our clinical trial applications and our clinical trials are conducted in accordance with 
GCP, the study plan and protocols for the trial. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or 
conduct our studies in accordance with regulatory requirements or our stated study plans and protocols, we will not be able to complete, or may be delayed 
in completing, the necessary preclinical studies to enable us or our strategic alliance partners to select viable product candidates for clinical trial application 
submissions and will not be able to, or may be delayed in our efforts to, successfully develop and commercialize such product candidates. 

We rely on third parties to design, conduct, supervise and monitor our preclinical studies and clinical trials, and if those third parties perform in an 
unsatisfactory manner, it may harm our business. 

We rely on third party clinical investigators, CROs, clinical data management organizations and consultants to design, conduct, supervise and monitor 
preclinical studies and clinical trials of our product candidates. Because we rely on third parties and do not have the ability to conduct preclinical studies or 
clinical trials independently, we have less control over the timing, quality and other aspects 

80

 
of preclinical studies and clinical trials than we would if we conducted them on our own, including our inability to control whether sufficient resources are 
applied to our programs. If any of our CROs are acquired or consolidated, these concerns are likely to be exacerbated and our preclinical studies or clinical 
trials may be further impacted due to potential integration, streamlining, staffing and logistical changes. These investigators, CROs and consultants are not 
our employees and we have limited control over the amount of time and resources that they dedicate to our programs. These third parties may have 
contractual relationships with other entities, some of which may be our competitors, which may draw time and resources from our programs. Further, these 
third parties may not be diligent, careful or timely in conducting our preclinical studies or clinical trials, resulting in the preclinical studies or clinical trials 
being delayed or unsuccessful. 

If we cannot contract with acceptable third parties on commercially reasonable terms, or at all, or if these third parties do not carry out their contractual 
duties, satisfy legal and regulatory requirements for the conduct of preclinical studies or clinical trials or meet expected deadlines, our preclinical and 
clinical development programs could be delayed and otherwise adversely affected. In all events, we are responsible for ensuring that each of our preclinical 
studies and clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. The FDA and other health authorities 
require clinical trials to be conducted in accordance with GCP, including conducting, recording and reporting the results of clinical trials to assure that data 
and reported results are credible and accurate and that the rights, integrity and confidentiality of clinical trial participants are protected. If we or our CROs 
fail to comply with these requirements, the data generated in our clinical trials may be deemed unreliable or uninterpretable and the FDA and other health 
authorities may require us to perform additional clinical trials. Our reliance on third parties that we do not control does not relieve us of these 
responsibilities and requirements. Any such event could adversely affect our business, financial condition, results of operations and prospects.

We rely on third parties in the supply and manufacture of our product candidates for our research, preclinical and clinical activities, and may do the 
same for commercial supplies of our product candidates. 

While we have built our own internal manufacturing capabilities, we have not yet manufactured our product candidates on a commercial scale, and may not 
be able to do so for any of our product candidates. In addition, we currently rely on third parties in the supply and manufacture of materials for our 
research, preclinical and clinical activities and may continue to do so for the foreseeable future. We may do the same for the commercial supply of our drug 
product. We use third parties to perform additional steps in the manufacturing process, such as the filling, finishing and labeling of vials and storage of our 
product candidates and we expect to do so for the foreseeable future. There can be no assurance that our supply of research, preclinical and clinical 
development drug candidates and other materials will not be limited, interrupted or restricted or will be of satisfactory quality or continue to be available at 
acceptable prices. Replacement of any of the third parties we may engage could require significant effort and expertise because there may be a limited 
number of qualified replacements. In addition, raw materials, reagents, and components used in the manufacturing process, particularly those for which we 
have no other source or supplier, may not be available, may not be suitable or acceptable for use due to material or component defects, or may introduce 
variability into the supply of our product candidates. Furthermore, with the increase of companies developing nucleic acid therapeutics, there may be 
increased competition for the supply of the raw materials that are necessary to make our oligonucleotides, which could severely impact the manufacturing 
of our product candidates.

We may be unable to identify manufacturers on acceptable terms or at all because the number of potential manufacturers is limited and they must be 
acceptable to the FDA or approved by foreign regulatory authorities Suppliers and manufacturers, including us, must meet applicable manufacturing 
requirements, including compliance with cGMP regulations, and undergo rigorous facility and process validation tests required by regulatory authorities in 
order to comply with regulatory standards. In the event that any of our suppliers or manufacturers fail to comply with such requirements or to perform their 
obligations to us in relation to quality, timing or otherwise, some of which may be out of their or our control, or if our supply of components or other 
materials becomes limited or interrupted for other reasons, we may be forced to increase the manufacturing of the materials ourselves, for which we 
currently have limited capabilities and resources, or enter into an agreement with another third party, which we may not be able to do on reasonable terms, 
if at all. Any interruption of the development or operation of the manufacturing of our product candidates, such as order delays for equipment or materials, 
equipment malfunction, quality control and quality assurance issues, regulatory delays and possible negative effects of such delays on supply chains and 
expected timelines for product availability, production yield issues, shortages of qualified personnel, discontinuation of a facility or business or failure or 
damage to a facility resulting from natural disasters, could result in the cancellation of shipments, loss of product in the manufacturing process or a shortfall 
in available product candidates or materials. In some cases, the technical skills or technology required to manufacture our product candidates may be 
unique or proprietary to the original manufacturer and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring 
such skills or technology to another third party and a feasible alternative may not exist. These factors would increase our reliance on such manufacturer or 
require us to obtain a license from such manufacturer in order to have another third party manufacture our product candidates. If we are required to change 
manufacturers for any reason, we will be required to verify that the new manufacturer maintains facilities and procedures that comply with quality 
standards and with all applicable regulations and guidelines. The delays associated with the verification of a new manufacturer could negatively affect our 
ability to develop product candidates in a timely manner or within budget. 

We may rely on third-party manufacturers if we receive regulatory approval for any product candidate. To the extent that we have existing, or enter into 
future, manufacturing arrangements with third parties, we will depend on these third parties to perform their 

81

 
obligations in a timely manner consistent with contractual and regulatory requirements, including those related to quality control and assurance. In 
complying with the manufacturing regulations of the FDA and other comparable foreign regulatory authorities, we and our third-party manufacturers must 
spend significant time, money, and effort in the areas of design and development, testing, production, record-keeping and quality control to assure that the 
products meet applicable specifications and other regulatory requirements. Although our agreements with third-party manufacturers require them to 
perform according to certain cGMP requirements such as those relating to quality control, quality assurance and qualified personnel, we cannot control the 
conduct of our third-party manufacturers to implement and maintain these standards. If any of our third-party manufacturers cannot successfully 
manufacture material that conforms to our specifications and the regulatory requirements of the FDA, or other comparable foreign authorities, we would be 
prevented from obtaining regulatory approval for our drug candidates unless and until we engage a substitute supplier that can comply with such 
requirements, which we may not be able to do. In addition, we and our third-party manufacturers responsible for the manufacture of commercial supplies of 
our products for which we retain regulatory approval, if any, are subject to inspection and approval by regulatory authorities before we may commence the 
manufacture and sale of any of such products, and thereafter are subject to ongoing inspection from time to time. Our third-party manufacturers may not be 
able to comply with applicable cGMP regulations or similar regulatory requirements outside of the United States. Our failure, or the failure of our third-
party manufacturers, to comply with applicable regulations could result in regulatory actions, such as the issuance of FDA Form 483 notices of 
observations, warning letters or sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal 
of approvals, license revocation, seizures or recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could 
significantly and adversely affect supplies of our products. Any such failure by us or any of our suppliers would significantly impact our ability to develop, 
obtain regulatory approval for or market our drug candidates, if approved.

We may also be required to enter into long-term manufacturing agreements that contain exclusivity provisions and/or substantial termination penalties 
which could have a material adverse effect on our business prior to or after commercialization of any of our product candidates. If we are unable to obtain 
or maintain third-party manufacturing for product candidates, or to do so on commercially reasonable terms, we may not be able to develop and 
commercialize our product candidates successfully. Failure to execute on our manufacturing requirements, either by us or by one of our third-party vendors, 
could adversely affect our business in a number of ways, including: 

•

•

•

•

•

•

an inability to initiate or continue clinical trials of product candidates under development; 

delays in submitting regulatory applications, or receiving regulatory approvals, for product candidates; 

loss of the cooperation of a collaborator; 

additional inspections by regulatory authorities; 

requirements to cease distribution or to recall batches of our product candidates; and 

in the event of approval to market and commercialize a product candidate, an inability to meet commercial demands for our products. 

If any of our product candidates are approved for marketing and commercialization and we are unable to develop sales, marketing and distribution 
capabilities on our own, or enter into agreements with third parties to perform these functions on acceptable terms, we will be unable to commercialize 
successfully any such future products. 

We currently have no sales, marketing or distribution capabilities. In addition, while our collaboration with Takeda and GSK will provide us with know-
how and experience related to commercialization, we have limited experience of our own. If any of our product candidates is approved, we will need to 
develop internal sales, marketing and distribution capabilities to commercialize such products, which would be expensive and time-consuming, or rely on 
or enter into additional collaborations with third parties to perform these services. If we decide to market our products directly, we will need to commit 
significant financial and managerial resources to develop a marketing and sales force with technical expertise and supporting distribution, administration 
and compliance capabilities. If we rely on third parties with such capabilities to market our products or decide to co-promote products with collaborators, 
we will need to establish and maintain marketing and distribution arrangements with third parties, and there can be no assurance that we will be able to 
enter into such arrangements on acceptable terms or at all. In entering into third-party marketing or distribution arrangements, any revenue we may receive 
will depend upon the efforts of the third parties and there can be no assurance that such third parties will establish adequate sales and distribution 
capabilities or be successful in gaining market acceptance of any approved 

82

 
product. If we are not successful in commercializing any product approved in the future, either on our own or through third parties, our business, financial 
condition, results of operations and prospects would be adversely affected. 

Risks Related to Managing Our Operations 

If we are unable to attract and retain qualified key management and scientists, staff, consultants and advisors, our ability to implement our business 
plan may be adversely affected. 

We are highly dependent upon our senior management and our scientific, clinical and medical staff and advisors. The loss of the service of any of the 
members of our senior management or other key employees could delay our research and development programs and materially harm our business, 
financial condition, results of operations and prospects. In addition, we expect that we will continue to have an increased need to recruit and hire qualified 
personnel as we advance our programs and expand operations. Failure to successfully recruit and retain personnel could impact our anticipated 
development plans and timelines. For example, in 2019, as a result of the stock price decline and our workforce reduction following the announcement of 
our decision to discontinue our development of suvodirsen in DMD, we have faced challenges in retaining and attracting employees to support our research 
and development efforts, and our failure to do so could have an adverse effect on our ability to execute on our business plan. We are dependent on the 
continued service of our technical personnel because of the highly technical and novel nature of our product candidates, platform and technologies and the 
specialized nature of the regulatory approval process. Replacing such personnel may be difficult and may take an extended period of time because of the 
limited number of individuals in our industry with the breadth of skills and experience required to successfully execute our business strategy, and we cannot 
assure you that we will be able to identify or employ qualified personnel for any such position on acceptable terms, if at all. Many of the biotechnology and 
pharmaceutical companies with whom we compete for qualified personnel have greater financial and other resources, different risk profiles and longer 
histories in the industry than we do. Because our management team and key employees are not obligated to provide us with continued service, they could 
terminate their employment with us at any time without penalty. We do not maintain key person life insurance policies on any of our management team 
members or key employees. Our future success will depend in large part on our continued ability to attract and retain highly qualified scientific, technical 
and management personnel, as well as personnel with expertise in preclinical and clinical testing, manufacturing, governmental regulation and 
commercialization. In order to do so, we may need to pay higher compensation or fees to our employees or consultants than we currently expect, and such 
higher compensation payments may have a negative effect on our operating results. We face increased competition for personnel from other companies, 
universities, public and private research institutions, government entities and other organizations. If we are unable to attract and retain qualified personnel, 
the rate and success at which we may be able to discover and develop our product candidates and implement our business plan will be limited.

As we continue our preclinical studies and clinical trials and advance to further clinical development, we may experience difficulties in managing our 
growth and expanding our operations. 

Although we have assembled a team of employees with experience developing medicines and obtaining regulatory approval to market those medicines, we 
have limited experience as a company in drug development. We have a robust and diverse pipeline of PN-modified, stereopure oligonucleotides, including 
programs using our editing, splicing, and silencing modalities. Our lead clinical programs are focused in, and aim to address, muscle diseases (DMD – 
splicing), hepatic diseases (AATD – editing), and CNS diseases (HD, ALS and FTD – silencing). As we advance product candidates through preclinical 
studies and clinical trials, we will need to expand our development, regulatory and manufacturing capabilities or contract with other organizations to 
provide these capabilities for us. In addition, we must manage our relationships with collaborators or partners, suppliers and other organizations, including 
our collaborations with GSK and Takeda. Our ability to manage our operations and future growth will require us to continue to improve our operational, 
financial and management controls, reporting systems and procedures. We may not be able to implement improvements to our management information 
and control systems in an efficient or timely manner and may discover deficiencies in existing systems and controls. In addition, our future growth may 
require significant capital expenditures and may divert financial resources from other projects, such as the development of our product candidates. If we are 
unable to effectively manage our future growth, our expenses may increase and our ability to generate revenue could be reduced.

Our employees, consultants and collaborators may engage in misconduct or other improper activities, including noncompliance with regulatory 
standards and requirements. 

We are exposed to the risk of fraud and other misconduct by our employees, consultants and collaborators. Such misconduct could include intentional 
failures to comply with FDA and other foreign agency regulations, provide accurate information to the FDA, comply with manufacturing standards 
required by the FDA or us, comply with federal and state healthcare fraud and abuse laws and regulations, report financial information or data accurately or 
disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and 
regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range 
of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct 
could 

83

 
also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our 
reputation. It is not always possible to identify and deter such misconduct, and the precautions we take to detect and prevent this activity may not be 
effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming 
from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending 
ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other 
sanctions. 

Security breaches, cyber security threats, loss of data and other disruptions could compromise sensitive information related to our business, prevent us 
from accessing critical information or expose us to liability, which could adversely affect our business and our reputation. 

In the ordinary course of our business, we, our CROs and other third parties, including our managed service providers (“MSPs”), on which we rely collect 
and store sensitive data, including legally protected patient health information, personally identifiable information about our employees, intellectual 
property, vendor information, and proprietary business information. We, along with our MSPs, manage and maintain our applications and data utilizing 
cloud-based and on-site systems. These applications and data encompass a wide variety of business-critical information, including research and 
development information and business and financial information. 

The secure processing, storage, maintenance and transmission of this critical information by us, or our CROs and other third parties with whom Wave does 
business, is vital to our operations and business strategy. We also have systems in place at our facilities to mitigate disruptions to our communications 
systems, including the prevention of a loss to our electrical systems. Although we are proactive in our approach and take measures to protect sensitive 
information from unauthorized access or disclosure, our information technology and infrastructure, or that of our CROs or other third party partners, may 
be vulnerable to attacks by hackers, viruses, breaches, interruptions due to employee error, malfeasance or other disruptions, lapses in compliance with 
privacy and security mandates, or damage from natural disasters, terrorism, war and telecommunication and electrical failures. For example, the COVID-19 
pandemic has led to an increase in those working remotely, including our employees and third parties with whom we do business, which increases our 
cyber security risk. This increased risk has created data accessibility concerns and has made us more susceptible to communication disruptions. In addition, 
cyberattacks, malicious internet-based activity and fraud are prevalent and continue to increase in frequency. Any such event, including a cyberattack, 
could compromise our networks, or that of our CROs or other third parties, and the information stored there could be accessed by unauthorized parties, 
publicly disclosed, lost or stolen. Furthermore, any such event could result in information theft, data corruption, operational disruption, damage to our 
reputation, or financial loss, and could subject us to liability or negatively impact our business operations.

As part of our robust data protection practices, we regularly conduct business continuity and disaster recovery testing of our key information systems and 
data. We have measures in place that are designed to detect and respond to such security incidents and breaches of privacy and security mandates. Any such 
access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal 
information (including GDPR, HIPAA and HITECH, among others), government enforcement actions and regulatory penalties. Unauthorized access, loss 
or dissemination could also disrupt our operations, including our ability to conduct research and development activities, process and prepare company 
financial information, manage various general and administrative aspects of our business and damage our reputation, any of which could adversely affect 
our business. For example, the loss of clinical trial data from completed or ongoing clinical trials, in addition to privacy concerns, could result in delays in 
our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. In addition, while we take measures to help ensure 
early detection, there can be no assurance that we, or our CROs and other third party partners, will promptly detect any such disruption or security breach, 
if at all. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of 
personal, confidential or proprietary information, we could incur liability and the further development of our product candidates could be delayed. 

Numerous federal, state and international laws address privacy, data protection and the collection, storing, sharing, use, disclosure and protection of 
personally identifiable information and other user data. Numerous states already have, and are looking to expand, data protection legislation. For example, 
in 2018, California enacted the California Consumer Privacy Act (“CCPA”), which became effective on January 1, 2020 giving California residents 
expanded privacy rights and protections and imposing fines and penalties. 2023 will also see new privacy laws in Virginia (effective January 1, 2023), 
Connecticut (effective July 1, 2023), Colorado (effective July 1, 2023), and Utah (effective December 31, 2023). Each year, many state legislatures 
continue to consider similar privacy laws, further expanding the patchwork of US privacy laws. State enforcement of data privacy and cybersecurity 
breaches has increased, along with the cost. California issued its first fine under the CCPA in the amount of $1.2 million, and the New York Attorney 
General has enforced its NY SHIELD Act by fining companies over $3,000,000. In addition, the Federal Trade Commission has zeroed in on data privacy 
and security as a central role, and 2023 may see increased enforcement and regulation.

Outside the United States, personally identifiable information and other user data is increasingly subject to legislation and regulations in numerous 
jurisdictions around the world, the intent of which is to protect the privacy of information that is collected, processed and transmitted in or from the 
governing jurisdiction. Foreign data protection, privacy, information security, user protection and other laws and regulations are often more restrictive than 
those in the United States. For example, in April 2016, European legislative bodies adopted the General Data Protection Regulation (“GDPR”), which 
became effective May 25, 2018, and which applies to any company, regardless of location, that collects or processes personal data of EU residents in 
connection with offering goods or services in the EU or monitoring the behavior of EU residents. The GDPR enhances data protection obligations for 
processors and controllers of personal data, including, for example, expanded disclosures about how personal information is to be used, limitations on 
retention of information, data minimization obligations, record-keeping requirements, mandatory data breach notification requirements, and correlated 
obligations on services providers. The GDPR also strictly regulates cross-border transfer of personal data, including requirements for data transfer impact 
assessments. Non-compliance with the GDPR may result in monetary penalties of up to €20 million or 4% of annual worldwide revenue, whichever is 
higher. In addition, post-Brexit the UK has also adopted its own version of the GDPR, which requires additional compliance measures. 

While we have taken steps to comply with applicable privacy laws and regulations, including the GDPR, by taking measures including enhancing our 
security procedures, updating our website, revising our clinical trial informed consents, adopting the standard contractual clauses for cross-border transfers 
of personal data, and entering into data processing agreements with relevant CROs and third party partners, we cannot assure you that our efforts to remain 
in compliance will be fully successful. The GDPR and other changes in laws or regulations associated with the enhanced protection of personal data may 
increase our costs of compliance and result in greater legal risks.

Foreign currency exchange rates may adversely affect our results. 

Due to our operations outside of the United States, we are exposed to market risk related to changes in foreign currency exchange rates. Historically, we 
have not hedged our foreign currency exposure. Changes in the relative values of currencies occur regularly and, in some instances, could materially 
adversely affect our business, our financial condition, the results of our operations or our cash flows.

For the years ended December 31, 2022 and 2021, changes in foreign currency exchange rates did not have a material impact on our historical financial 
position, our business, our financial condition, the results of our operations or our cash flows. A hypothetical 10% change in foreign currency rates would 
not have a material impact on our historical financial position or results of operations. However, there can be no assurance that changes in foreign currency 
exchange rates will not have a material adverse impact on us in the future.

The U.S. tax legislation and future changes to applicable U.S. or foreign tax laws and regulations may have a material adverse effect on our business, 
financial condition and results of operations. 

We are subject to income and other taxes in the United States and foreign jurisdictions. Changes in laws and policy relating to taxes or trade, including 
increases in tax rates or modifications, technical corrections or clarifications to tax laws, such as the Tax Cuts and Jobs Act of 2017, which eliminates the 
option to deduct research and development expenditures currently and requires corporations to capitalize and amortize them over a period of years, may 
have an adverse effect on our business, financial condition and results of operations. This Annual Report on Form 10-K does not discuss any such tax 
legislation or changes to tax laws and legislation, or the manner in which it might affect us or purchasers of our securities. We urge our investors to consult 
with their legal and tax advisors with respect to such legislation and the potential tax consequences of investing in our securities. 

We are also subject to different tax regulations in each of the jurisdictions where we conduct our business or where our management is located. We expect 
the scope and extent of regulation in the jurisdictions in which we conduct our business, or where our management is located, as well as regulatory 
oversight and supervision, to generally continue to increase. Generally, future changes in applicable U.S. or foreign tax laws and regulations, or their 
interpretation and application could have an adverse effect on our business, financial condition and results of operations.

Inadequate funding for the FDA, the SEC and other government agencies, or a work slowdown or stoppage at those agencies as part of a broader 
federal government shutdown, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from 
being developed or commercialized in a timely manner, or otherwise prevent those agencies from performing normal business functions on which the 
operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, the 
ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy 

85

 
 
changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC and other government 
agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is 
inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also extend the time necessary for new drugs to be reviewed and/or approved by necessary government 
agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain 
regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. 
Additionally, the FDA and regulatory authorities outside the United States have imposed and may continue to impose various restrictions or other policy 
measures in response to the COVID-19 pandemic. If a prolonged government shutdown or slowdown occurs, it could significantly impact the ability of the 
FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government 
shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Risks Related to Our Intellectual Property 

If we are not able to obtain and enforce market exclusivity for our technologies or product candidates, development and commercialization of our 
product candidates may be adversely affected. 

In our industry, the majority of an innovative product’s commercial value is usually realized during the period in which it has market exclusivity. Market 
exclusivity is comprised of both patent and other intellectual property protection, as well as regulatory exclusivity. In the United States and some other 
countries, when market exclusivity expires and generic versions of a product are approved and marketed, there usually are very substantial and rapid 
declines in the product’s sales. Accordingly, our success depends in part on our ability to obtain and maintain patents and other forms of intellectual 
property rights, including trademarks, trade secrets and in-licenses of intellectual property rights of others, for our product candidates and platform 
technologies, methods used to manufacture our product candidates, methods of patient stratification and methods for treating patients using our product 
candidates, as well as our ability to preserve our trade secrets, to prevent third parties from infringing upon our proprietary rights and to operate without 
infringing upon the proprietary rights of others. Certain research and development activities involved in pharmaceutical development are exempt from 
patent infringement in the United States and other jurisdictions, for example, in the United States by the provisions of 35 U.S.C. § 271(e)(1) (the “Safe 
Harbor”). However, in the United States and certain other jurisdictions, the Safe Harbor exemption terminates when the sponsor submits an application for 
marketing approval (e.g., a New Drug Application (“NDA”) in the United States). Therefore, the risk that a third party might allege patent infringement 
may increase as our products approach commercialization. We may not be able to apply for patents or obtain patent protection on certain aspects of our 
product candidates or our platform in a timely fashion or at all. Our existing issued and granted patents and any future patents we obtain may not be 
sufficiently broad to prevent others from using our technology or from developing competing products and technology. There is no guarantee that any of 
our pending patent applications will result in issued or granted patents, that any of our issued or granted patents will not later be found to be invalid or 
unenforceable, or that any issued or granted patents will include claims that are sufficiently broad to cover our product candidates, our platform 
technologies, or any methods relating to them, or to provide meaningful protection from our competitors. Moreover, the patent position of biotechnology 
and pharmaceutical companies can be highly uncertain and involves complex legal and factual questions. We will be able to protect our proprietary rights 
from unauthorized use by third parties only to the extent that our current and future proprietary technology and product candidates are covered by valid and 
enforceable patents or are effectively maintained as trade secrets. If third parties disclose or misappropriate our proprietary rights, it may materially and 
adversely impact our position in the market.

Legal issues related to the patentability of biopharmaceuticals, and methods of their manufacture and use, are complex and uncertain in some countries. In 
some countries, applicants are not able to protect methods of treating human beings or medical treatment processes. Intellectual property protection varies 
throughout the world and is subject to change over time. Certain jurisdictions have enacted various rules and laws precluding issuance of patents 
encompassing any methods a doctor may practice on a human being or any other animal to treat a disease or condition. Further, many countries have 
enacted laws and regulatory regimes that do not allow patent protection for methods of use of known compounds. Particularly given that some of our 
product candidates may represent stereopure versions of previously described oligonucleotides, it may be difficult or impossible to obtain patent protection 
for them in relevant jurisdictions. Thus, in some countries and jurisdictions, it may not be possible to patent some of our product candidates at all. In some 
countries and jurisdictions, only composition claims may be obtained, and only when those compositions are or contain compounds that are new and/or 
novel. Also, patents issued with composition claims (i.e., covering product candidates) cannot always be enforced to protect methods of using those 
compositions to treat or diagnose diseases or medical conditions. In such countries or jurisdictions, enforcement of patents to protect our product 
candidates, or their uses, may be difficult or impossible. Lack of patent protection in such cases may have a materially adverse effect on our business and 
financial condition. 

Furthermore, given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such 
candidates, their manufacture or their use might expire before or shortly after those candidates receive regulatory 

86

 
approval and are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from 
commercializing products similar or identical to ours. We expect to seek extensions of patent terms where these are available upon regulatory approval in 
those countries where we are prosecuting patents. This includes in the United States under the Drug Price Competition and Patent Term Restoration Act of 
1984, which permits a patent term extension of up to five years beyond the expiration of the patent. However, the applicable authorities, including the FDA 
in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment of whether such extensions are 
available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request. If this occurs, our competitors may take 
advantage of our investment in development and clinical trials by referencing our clinical and preclinical data and launch their product earlier than might 
otherwise be possible. 

The U.S. Patent and Trademark Office (“USPTO”) and various foreign governmental patent agencies require compliance with a number of procedural, 
documentary, fee payment and other provisions during the patent prosecution process. There are situations in which noncompliance can result in 
abandonment or lapse of a patent or patent application, or loss of right to enforce patent claims, resulting in partial or complete loss of patent rights in the 
relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case. The standards applied 
by the USPTO and foreign patent offices in granting patents are not uniform, can vary substantially from country to country, and are not always applied 
predictably, requiring country-specific patent expertise in each jurisdiction in which patent protection is sought. For example, there is no uniform 
worldwide policy regarding patentable subject matter or the scope of claims allowable in biotechnology and pharmaceutical patents. As such, we do not 
know the degree of future protection that we will have on our proprietary products and technologies. While we will endeavor to try to protect our product 
candidates and platform technology with intellectual property rights such as patents, as appropriate, the process of filing and prosecuting patent 
applications, and obtaining, maintaining and defending patents is time-consuming, expensive, uncertain, and sometimes unpredictable. 

In addition, periodic changes to the patent laws and rules of patent offices around the world, including the USPTO can have a significant impact on our 
ability to protect our technology and enforce our intellectual property rights. For example, the America Invents Act, enacted in 2011, involved significant 
changes in patent legislation. Furthermore, the U.S. Supreme Court has ruled on several patent cases in recent years, some of which cases either narrow the 
scope of patent protection available in certain circumstances or weaken the rights of patent owners in certain situations. The 2013 decision by the U.S. 
Supreme Court in Association for Molecular Pathology v. Myriad Genetics, Inc. precludes a claim to a nucleic acid having a stated nucleotide sequence 
which is identical to a sequence found in nature and unmodified. We currently are not aware of an immediate impact of this decision on our patents or 
patent applications because we are developing oligonucleotides which contain modifications that we believe are not found in nature. However, we cannot 
make assurances that the interpretations of this decision or subsequent rulings will not adversely impact our patents or patent applications. In addition to 
increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value 
of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, and by analogous bodies around the world, the 
laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing 
patents and patents that we might obtain in the future. For example, in 2012, European countries and the European Parliament agreed to a legislative 
package that would create a unitary patent protection system in the EU; aspects of this system are scheduled to be implemented beginning in 2023 for at 
least some European countries. The impact of the proposed unitary patent protection system on patents in Europe is currently unclear.

Once granted, patents may remain open to opposition, interference, re-examination, post-grant review, inter partes review, nullification or derivation action 
in court or before patent offices or similar proceedings for a given period after allowance or grant, during which time third parties can raise objections 
against such initial grant. In the course of such proceedings, which may continue for a protracted period of time, the patent owner may be compelled to 
limit the scope of the allowed or granted claims attacked or may lose the allowed or granted claims altogether. In addition, there can be no assurance that: 

•

Others will not or may not be able to make, use or sell compounds that are the same as or similar to our product candidates but that are 
not covered by the claims of the patents that we own or license. 

• We or our licensors, collaborators or any future collaborators are the first to make the inventions covered by each of our issued patents 

and pending patent applications that we own or license. 

• We or our licensors, collaborators or any future collaborators are the first to file patent applications covering certain aspects of our 

inventions. 

•

•

Others will not independently develop similar or alternative technologies or duplicate any of our technologies without infringing our 
intellectual property rights. 

A third party may not challenge, invalidate, circumvent or weaken our patents, or that, if any of these events should occur, that a court 
would hold that our patents are valid, enforceable and infringed. 

87

 
•

Any issued patents that we own or have licensed will provide us with any competitive advantages, or will not be challenged, 
invalidated, circumvented or weakened by third parties. 

• We may develop additional proprietary technologies that are patentable. 

•

•

The patents of others will not have an adverse effect on our business. 

Our competitors do not conduct research and development activities in countries where we do not have enforceable patent rights and 
then use the information learned from such activities to develop competitive products for sale in our major commercial markets. 

We license patent rights from third-party owners or licensees. If such owners or licensees do not properly or successfully obtain, maintain or enforce 
the patents underlying such licenses, or if they retain or license to others any competing rights, our competitive position and business prospects may be 
adversely affected. 

We license patent rights from third parties that we may use from time to time to protect certain aspects of our technology and programs. We may license 
additional third-party intellectual property in the future. To the extent that we use, and ultimately rely on, in-licensed technologies in our platform and our 
programs, our success will depend in part on the ability of our licensors to obtain, maintain and enforce patent protection for those in-licensed technologies. 
Our licensors may not successfully prosecute the patent applications licensed to us. Even if patents issue or are granted, our licensors may fail to maintain 
these patents, may determine not to pursue litigation against other companies that are infringing these patents, or may pursue litigation less aggressively 
than we would. Further, we may not obtain exclusive rights, which would allow for third parties to develop competing products. Without protection for, or 
exclusive right to, the intellectual property we license, other companies might be able to offer substantially identical products for sale, which could 
adversely affect our competitive business position and harm our business prospects. In addition, we may sublicense our rights under our third-party licenses 
to current or future collaborators or any future strategic partners. Any impairment of these sublicensed rights could result in reduced revenue under any 
future collaboration agreements we may enter into or result in termination of an agreement by one or more of our current or future collaborators or any 
future strategic partners. 

Other companies or organizations may challenge our or our licensors’ patent rights or may assert patent rights that prevent us from developing and 
commercializing our products. 

Nucleic acid therapeutics is a relatively new scientific field, the commercial exploitation of which has resulted in many different patents and patent 
applications from organizations and individuals seeking to obtain patent protection in the field. We have obtained grants and issuances of patents in this 
field. The issued patents and pending patent applications in the United States and in key markets around the world that we own or license claim certain 
methods, compositions and processes relating to the discovery, development, manufacture and/or commercialization of oligonucleotides and/or our 
platform. 

As the field of oligonucleotides matures, patent applications are being processed by national patent offices around the world. There is uncertainty about 
which patents will issue, and, if they do, as to when, to whom, and with what claims. It is likely that there will be significant litigation in the courts and 
other proceedings, such as interference, reexamination and opposition proceedings, in various patent offices relating to patent rights in the oligonucleotides 
field. In many cases, the possibility of appeal or opposition exists for either us or our opponents, and it may be years before final, unappealable rulings are 
made with respect to these patents in certain jurisdictions. The timing and outcome of these and other proceedings is uncertain and may adversely affect our 
business, particularly if we are not successful in defending the patentability and scope of our pending and issued patent claims or if third parties are 
successful in obtaining claims that cover any of our product candidates or our platform. In addition, third parties may attempt to invalidate our intellectual 
property rights. Even if our rights are not directly challenged, invalidated or circumvented, disputes could lead to the weakening of our intellectual property 
rights. Our defense against any attempt by third parties to challenge, invalidate, circumvent or weaken our intellectual property rights could be costly to us, 
could require significant time and attention of our management and could adversely affect our business and our ability to successfully compete in the field 
of oligonucleotides. 

We may not be able to protect our intellectual property rights throughout the world. 

Obtaining a valid and enforceable issued or granted patent covering our technology in the United States and worldwide can be extremely costly. In 
jurisdictions where we have not obtained patent protection, competitors may use our technology to develop their own products and further, may export 
otherwise infringing products to territories where we have patent protection, but where it is more difficult to enforce a patent as compared to the United 
States. Competitor products may compete with our future products in jurisdictions where we do not have issued or granted patents or where our issued or 
granted patent claims or other intellectual property rights are not sufficient to prevent competitor activities in these jurisdictions. The legal systems of 
certain countries, particularly certain developing countries, make it difficult to enforce patents and such countries may not recognize other types of 
intellectual property protection, particularly relating to biopharmaceuticals. This could make it difficult for us to prevent the infringement of our 

88

 
patents or marketing of competing products in violation of our proprietary rights generally in certain jurisdictions. Proceedings to enforce our patent rights 
in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business. 

We generally file a provisional patent application first (a priority filing) at the USPTO. A Patent Cooperation Treaty (“PCT”) application is usually filed 
within 12 months after the priority filing. Regional and/or national patent applications may be pursued outside of the United States, either based on a PCT 
application or as a direct filing, in some cases claiming priority to a prior U.S. or PCT filing. Some of our cases have been filed in multiple jurisdictions, 
including major market jurisdictions. We also commonly enter the national stage in the United States through a PCT filing. We have so far not filed for 
patent protection in all national and regional jurisdictions where such protection may be available. In addition, we may decide to abandon national and 
regional patent applications before grant. Finally, the grant proceeding of each national or regional patent is an independent proceeding which may lead to 
situations in which applications might in some jurisdictions be refused by the relevant registration authorities, while granted by others. It is also quite 
common that depending on the country, different scopes of patent protection may be granted on the same product or technology. 

The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the United States, and many companies have 
encountered significant difficulties in protecting and defending such rights in such jurisdictions. If we or our licensors encounter difficulties in protecting, 
or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of these 
rights may be diminished and we may face additional competition from others in those jurisdictions. Many countries have compulsory licensing laws under 
which a patent owner may be compelled to grant licenses to third parties, allowing competitors to manufacture and sell their own versions of our product, 
thereby reducing our sales. In addition, many countries do not permit enforcement of patents, or limit the enforceability of patents against government 
agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such a 
patent. If we or any of our licensors, collaborators or present or future partners are forced to grant a license to third parties with respect to any patents 
relevant to our business, our competitive position in the relevant jurisdiction may be impaired and our business and results of operations may be adversely 
affected. 

The requirements for patentability may differ in certain countries. For example, some jurisdictions may have heightened requirements for patentability 
compared to others, and may specifically require a detailed description of medical uses of a claimed drug. In some jurisdictions, unlike the United States, 
there is no link between regulatory approval of a drug and its patent status. Furthermore, generic or biosimilar drug manufacturers or other competitors may 
challenge the scope, validity or enforceability of our or our licensors’ or collaborators’ patents, requiring us or our licensors or collaborators to engage in 
complex, lengthy and costly litigation or other proceedings. Generic or biosimilar drug manufacturers may develop, seek approval for, and launch generic 
versions of our products. Accordingly, our and our licensors’ and collaborators’ efforts to enforce intellectual property rights around the world may be 
inadequate to obtain a significant commercial advantage from the intellectual property that we own or license.

We or our licensors, collaborators or any future strategic partners may become subject to third party claims or litigation alleging infringement of 
patents or other proprietary rights or seeking to invalidate patents or other proprietary rights, and we may need to resort to litigation to protect or 
enforce our patents or other proprietary rights, all of which could be costly and time consuming, or delay or prevent the development and 
commercialization of our product candidates, or put our patents and other proprietary rights at risk. 

We or our licensors, collaborators or any future strategic partners may be subject to third-party claims for infringement or misappropriation of patent or 
other proprietary rights. We are generally obligated under our license or collaboration agreements to indemnify and hold harmless our licensors or 
collaborators for damages arising from intellectual property infringement by us. If we or our licensors, collaborators or any future strategic partners are 
found to infringe a third-party patent or other intellectual property rights, we could be required to pay damages, potentially including treble damages, if we 
are found to have willfully infringed. In addition, we or our licensors, collaborators or any future strategic partners may choose to seek, or be required to 
seek, a license from a third party, which may not be available on acceptable terms, if at all. Even if a license can be obtained on acceptable terms, the rights 
may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. If we fail to obtain a 
required license, we or our collaborator, or any future collaborator, may be unable to effectively market product candidates based on our technology, which 
could limit our ability to generate revenue or achieve profitability and possibly prevent us from generating revenue sufficient to sustain our operations. In 
addition, we may find it necessary to pursue claims or initiate lawsuits to protect or enforce our patent or other intellectual property rights. The cost to us in 
defending or initiating any litigation or other proceeding relating to patent or other proprietary rights, even if resolved in our favor, could be substantial, and 
litigation would divert our management’s attention. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively 
than we can because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of patent litigation or other 
proceedings could delay our research and development efforts and limit our ability to continue our operations. 

89

 
If we were to initiate legal proceedings against a third party to enforce a patent covering one of our products or our technology, the defendant could 
counterclaim that our patent is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or 
unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, 
lack of novelty, lack of written disclosure, obviousness, or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone 
connected with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. The 
outcome following legal allegations of invalidity and unenforceability during patent litigation is unpredictable. With respect to the validity question, for 
example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant 
were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on one or more of 
our products or certain aspects of our platform technology. Such a loss of patent protection could negatively impact our business. Patents and other 
intellectual property rights also will not protect our technology if competitors design around our protected technology without legally infringing our patents 
or other intellectual property rights. 

Intellectual property rights of third parties could adversely affect our ability to commercialize our product candidates, and we might be required to 
litigate or obtain licenses from third parties in order to develop or market our product candidates. Such litigation or licenses could be costly or not 
available on commercially reasonable terms. 

Because the oligonucleotide intellectual property landscape is still evolving and our product candidates have not yet reached commercialization, it is 
difficult to conclusively assess our freedom to operate. There are numerous companies that have pending patent applications and issued patents directed to 
certain aspects of oligonucleotides. We are aware of third-party competitors in the oligonucleotide therapeutics space, whose patent filings and/or issued 
patents may include claims directed to targets and/or products related to some of our programs. It is possible that at the time that we commercialize our 
products these third-party patent portfolios may include issued patent claims that cover our products or critical features of their production or use. Our 
competitive position may suffer if patents issued to third parties or other third-party intellectual property rights cover, or may be alleged to cover, our 
products or elements thereof, or methods of manufacture or use relevant to our development plans. In such cases, we may not be in a position to develop or 
commercialize product candidates unless we successfully pursue litigation to nullify or invalidate the third party intellectual property right concerned or 
enter into a license agreement with the intellectual property right holder, if available on commercially reasonable terms. 

It is also possible that we have failed to identify relevant third-party patents or applications. For example, U.S. applications filed before November 29, 
2000, and certain U.S. applications filed after that date that will not be filed outside the United States remain confidential until patents issue. Patent 
applications in the United States and elsewhere are published approximately 18 months after the earliest filing date for which priority is claimed, with such 
earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our products or platform technology could have 
been filed by others without our knowledge. Additionally, pending patent applications which have been published can, subject to certain limitations, be 
later amended in a manner that could cover our platform technologies, our products or the use of our products. Third party intellectual property right 
holders may also actively bring infringement claims against us. We cannot guarantee that we will be able to successfully settle or otherwise resolve such 
infringement claims. If we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or continue costly, 
unpredictable and time-consuming litigation and may be prevented from or experience substantial delays in marketing our products. If we fail in any such 
dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from commercializing any of our product candidates 
that are held to be infringing. We might, if possible, also be forced to redesign product candidates so that we no longer infringe the third-party intellectual 
property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that 
we would otherwise be able to devote to our business. 

If we fail to comply with our obligations under any license, collaboration or other agreement, we may be required to pay damages and could lose 
intellectual property rights that are necessary for developing and protecting our product candidates, or we could lose certain rights to grant sublicenses. 

There are many issued patents and/or pending patent applications that claim aspects of oligonucleotide compositions, chemistry and/or modifications that 
we may want or need to apply to our product candidates. There are also many issued patents and/or pending patent applications that claim targeted genes or 
portions of genes that may be relevant for the oligonucleotides we wish to develop. We are aware of third-party competitors in the oligonucleotide 
therapeutics space whose patent filings and/or issued patents may include claims directed to targets and/or product candidates related to some of our 
development programs. It is possible that these third-party patent portfolios may include issued patent claims that cover our product candidates or critical 
features of their production or use. Thus, it is possible that one or more organizations will hold patent rights to which we will need or want a license. If 
those organizations refuse to grant us a license to such patent rights on reasonable terms, or at all, we may not be able to market products or perform 
research and development or other activities covered by these patents.

90

 
Our technology licenses and any future licenses we enter into are likely to impose various development, commercialization, funding, milestone, royalty, 
diligence, sublicensing, insurance, patent prosecution and enforcement, and/or other obligations on us. If we breach any of these imposed obligations, or 
use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may have the right to terminate 
the license, which could result in us being unable to develop, manufacture and sell products that are covered by the licensed technology or enable a 
competitor to gain access to the licensed technology. Moreover, our licensors may own or control intellectual property that has not been licensed to us and, 
as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the licensor’s rights. In addition, while we 
cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future products, if any, the amounts may be 
significant. The amount of our future royalty obligations will depend on the technology and intellectual property we use in products that we successfully 
develop and commercialize, if any. Therefore, even if we successfully develop and commercialize products, we may be unable to achieve or maintain 
profitability. 

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed. 

In addition to seeking patent protection for certain aspects of our product candidates, we also consider trade secrets, including confidential and unpatented 
know-how, improvements and technological innovation important to the maintenance of our competitive position. We protect trade secrets and confidential 
and unpatented know-how, improvements and technological innovation, in part, by entering into non-disclosure and confidentiality agreements with parties 
who have access to such knowledge, such as our employees, corporate collaborators, outside scientific collaborators, CROs, contract manufacturers, 
consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and 
consultants that obligate them to maintain confidentiality and assign their inventions to us. Despite these efforts, any of these parties may breach the 
agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. 
Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is 
unpredictable. In addition, some courts in the United States and certain foreign jurisdictions are less willing or unwilling to protect trade secrets. If any of 
our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them from using that 
technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our 
competitive position would be harmed. 

We may be subject to claims that we or our employees or consultants have wrongfully used or disclosed alleged trade secrets of our employees’ or 
consultants’ former employers or their clients. These claims may be costly to defend and if we do not successfully do so, we may be required to pay 
monetary damages and may lose valuable intellectual property rights or personnel. 

Many of our employees were previously employed at universities or biotechnology or pharmaceutical companies, including our competitors or potential 
competitors. Although no claims against us are currently pending, we may be subject to claims that these employees or we have inadvertently or otherwise 
used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. If we 
fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. A loss of key 
research personnel or their work product could hamper our ability to commercialize, or prevent us from commercializing, our product candidates, which 
could severely harm our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a 
distraction to management. 

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our 
business may be adversely affected. 

Our trademarks or trade names may be infringed, challenged, invalidated, circumvented, weakened or declared generic or determined to be infringing on 
other marks. We may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we need for 
name recognition by potential partners or customers in our markets of interest. If we are unable to establish name recognition based on our trademarks and 
trade names, we may not be able to compete effectively and our business may be adversely affected. 

Risks Related to Our Being a Singapore Company 

We are a Singapore incorporated company and it may be difficult to enforce a judgment of U.S. courts for civil liabilities under U.S. federal securities 
laws against us, our directors or our officers in Singapore. 

We are incorporated under the laws of the Republic of Singapore, and certain of our directors are residents outside the United States. Moreover, a 
significant portion of our consolidated assets are located outside the United States. Although we are incorporated outside the United States, we have agreed 
to accept service of process in the United States through our agent designated for that purpose. 

91

 
Nevertheless, because a majority of the consolidated assets owned by us are located outside the United States, any judgment obtained in the United States 
against us may not be enforceable within the United States. 

There is no treaty between the United States and Singapore providing for the reciprocal recognition and enforcement of judgments in civil and commercial 
matters and a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not 
predicated solely upon the federal securities laws, would, therefore, not be automatically enforceable in Singapore. There is uncertainty as to whether 
judgments of courts in the United States based upon the civil liability provisions of the federal securities laws of the United States would be recognized or 
enforceable in Singapore. In addition, holders of book-entry interests in our shares will be required to be registered shareholders as reflected in our 
shareholder register in order to have standing to bring a shareholder action and, if successful, to enforce a foreign judgment against us, our directors or our 
executive officers in the Singapore courts. The administrative process of becoming a registered holder could result in delays prejudicial to any legal 
proceedings or enforcement action. Consequently, it may be difficult for investors to enforce against us, our directors or our officers in Singapore 
judgments obtained in the United States which are predicated upon the civil liability provisions of the federal securities laws of the United States.

We are incorporated in Singapore and our shareholders may have more difficulty in protecting their interests than they would as shareholders of a 
corporation incorporated in the United States. 

Our corporate affairs are governed by our constitution and by the laws governing corporations incorporated in Singapore. The rights of our shareholders 
and the responsibilities of the members of our board of directors under Singapore law are different from those applicable to a corporation incorporated in 
the United States. Principal shareholders of Singapore companies do not owe fiduciary duties to minority shareholders, as compared, for example, to 
controlling shareholders in corporations incorporated in Delaware. Our public shareholders may have more difficulty in protecting their interests in 
connection with actions taken by our management, members of our board of directors or our principal shareholders than they would as shareholders of a 
corporation incorporated in the United States. 

In addition, only persons who are registered as shareholders in our shareholder register are recognized under Singapore law as shareholders of our 
company. Only registered shareholders have legal standing to institute shareholder actions against us or otherwise seek to enforce their rights as 
shareholders. Investors in our shares who are not specifically registered as shareholders in our shareholder register (for example, where such shareholders 
hold shares indirectly through the Depository Trust Company) are required to become registered as shareholders in our shareholder register in order to 
institute or enforce any legal proceedings or claims against us, our directors or our executive officers relating to shareholder rights. Holders of book-entry 
interests in our shares may become registered shareholders by exchanging their book-entry interests in our shares for certificated shares and being 
registered in our shareholder register. Such process could result in administrative delays which may be prejudicial to any legal proceeding or enforcement 
action.

We are subject to the laws of Singapore, which differ in certain material respects from the laws of the United States. 

As a company incorporated under the laws of the Republic of Singapore, we are required to comply with the laws of Singapore, certain of which are 
capable of extra-territorial application, as well as our constitution. In particular, we are required to comply with certain provisions of the Securities and 
Futures Act 2001 of Singapore (the “SFA”), which prohibit certain forms of market conduct and require certain information disclosures, and impose 
criminal and civil penalties on corporations, directors and officers in respect of any breach of such provisions. We are required to comply with the 
Singapore Code on Take-Overs and Mergers (the “Singapore Takeover Code”), which specifies, among other things, certain circumstances in which a 
general offer is to be made upon a change in effective control, and further specifies the manner and price at which voluntary and mandatory general offers 
are to be made. 

We are also subject to Section 34 of the Singapore Patents Act, which provides that a person residing in Singapore is required to obtain written 
authorization from the Singapore Registrar of Patents (the “Registrar”) before filing an application for a patent for an invention outside of Singapore, unless 
certain conditions have been satisfied. A violation of Section 34 is a criminal offense punishable by a fine not exceeding S$5,000, or imprisonment for a 
term not exceeding two years, or both. There have been some instances where we have undertaken filings outside of Singapore, and there may be instances 
where we are required to make such filings in the future, without first obtaining written authorization from the Registrar. We have notified the Registrar of 
such filings and we have since implemented measures to address the requirements of Section 34 moving forward. To date, the Registrar has offered a 
compound of some of the offences considered against payment of a sum of S$50 to S$150 per considered case. Under Singapore law, the Registrar has 
discretion to offer a compound of such offences against payment of a sum of money of up to S$2,000, or to prosecute the offence subject to the other 
penalties noted above. Per requests in the Registrar’s most recent decision, we have submitted approximately 140 patent applications in multiple patent 
families, most of which are related to previously reported applications, to the Intellectual Property Office of Singapore (“IPOS”). The IPOS may consider 
the filing of some or all of these applications to have breached Section 34 requirements per IPOS’ current interpretation of Section 34, and we are waiting 
for IPOS’ decision on these 

92

 
applications. We cannot assure you that the Registrar will offer to compound any such violations of Section 34, or that any offer to compound will be for an 
amount similar to previous compound offer.

The laws of Singapore and of the United States differ in certain significant respects. The rights of our shareholders and the obligations of our directors and 
officers under Singapore law (including under the Companies Act 1967 of Singapore (the “Singapore Companies Act”) are different from those applicable 
to a company incorporated in the State of Delaware in material respects, and our shareholders may have more difficulty and less clarity in protecting their 
interests in connection with actions taken by our management, members of our board of directors or our affiliated shareholders than would otherwise apply 
to a company incorporated in the State of Delaware. 

The application of Singapore law, in particular, the Singapore Companies Act may, in certain circumstances, impose more restrictions on us and our 
shareholders, directors and officers than would otherwise be applicable to a company incorporated in the State of Delaware. For example, the Singapore 
Companies Act requires directors to act with a reasonable degree of diligence and, in certain circumstances, imposes criminal liability for specified 
contraventions of particular statutory requirements or prohibitions. In addition, pursuant to the provisions of the Singapore Companies Act, shareholders 
holding 10% or more of the total number of paid-up shares carrying the right of voting in general meetings may require the convening of an extraordinary 
general meeting of shareholders by our directors. If our directors fail to comply with such request within 21 days of the receipt thereof, the original 
requisitioning shareholders, or any of them holding more than 50% of the voting rights represented by the original requisitioning shareholders, may 
proceed to convene such meeting, and we will be liable for the reasonable expenses incurred by such requisitioning shareholders. We are also required by 
the Singapore Companies Act to deduct such corresponding amounts from fees or other remuneration payable by us to such non-complying directors. 

We are subject to the Singapore Takeover Code, which requires a person acquiring 30% or more of our voting shares to conduct a takeover offer for all 
of our voting shares. This could have the effect of discouraging, delaying or preventing a merger or acquisition and limit the market price of our 
ordinary shares. 

We are subject to the Singapore Takeover Code. The Singapore Takeover Code contains provisions that may delay, deter or prevent a future takeover or 
change in control of our company and limit the market price of our ordinary shares for so long as we remain a public company with more than 50 
shareholders and net tangible assets of S$5 million (Singapore dollars) or more. For example, under the Singapore Takeover Code, any person acquiring, 
whether by a series of transactions over a period of time or not, either on such person’s own or together with parties acting in concert with such person, 
30% or more of our voting shares, or if such person holds, either on such person’s own or together with parties acting in concert with such person, between 
30% and 50% (both inclusive) of our voting shares, and if such person (or parties acting in concert with such person) acquires additional voting shares 
representing more than 1% of our voting shares in any six-month period, must, except with the consent of Securities Industry Council in Singapore, extend 
a takeover offer for our remaining voting shares in accordance with the Singapore Takeover Code. Therefore, any investor seeking to acquire a significant 
stake in our company may be deterred from doing so if, as a result, such investor would be required to conduct a takeover offer for all of our voting shares. 

These same provisions could discourage potential investors from acquiring a stake or making a significant investment in our company and may 
substantially impede the ability of our shareholders to benefit from a change of effective control and, as a result, may adversely affect the market price of 
our ordinary shares and the ability to realize any benefits from a potential change of control. 

For a limited period of time, our directors have general authority to allot and issue new ordinary shares on terms and conditions and for such purposes 
as may be determined by our board of directors in its sole discretion. 

Under Singapore law, we may only allot and issue new shares with the prior approval of our shareholders in a general meeting. At our most recent annual 
general meeting of shareholders, our shareholders provided our directors with a general authority, subject to the provisions of the Singapore Companies Act 
and our constitution, to allot and issue any number of new ordinary shares and/or make or grant offers, agreements, options or other instruments (including 
the grant of awards or options pursuant to our equity-based incentive plans and agreements in effect from time to time) that might or would require 
ordinary shares to be allotted and issued (collectively, the “Instruments”); and unless revoked or varied by us in a general meeting, such authority will 
continue in force until the earlier of (i) the conclusion of our next annual general meeting of shareholders, or (ii) the expiration of the period within which 
our next annual general meeting of shareholders is required by law to be held. Subject to the general requirements of the Singapore Companies Act and our 
constitution, the general authority given to our directors by our shareholders to allot and issue ordinary shares and/or make or grant the Instruments may be 
exercised by our directors on such terms and conditions, for such purposes and for consideration as they may in their sole discretion deem fit, and with such 
rights or restrictions as they may think fit to impose and as are set forth in our constitution. Any additional issuances of new ordinary shares and/or any 
grant of the Instruments by our directors may dilute our shareholders’ interests in our ordinary shares and/or adversely impact the market price of our 
ordinary shares. 

93

 
We may be or become a passive foreign investment company, which could result in adverse U.S. federal income tax consequences to U.S. Holders. 

The rules governing passive foreign investment companies (“PFICs”) can have adverse effects for U.S. federal income tax purposes. The tests for 
determining PFIC status for a taxable year depend upon the relative values of certain categories of assets and the relative amounts of certain kinds of 
income. The determination of whether we are a PFIC, which must be made annually after the close of each taxable year, depends on the particular facts and 
circumstances (such as the valuation of our assets, including goodwill and other intangible assets) and may also be affected by the application of the PFIC 
rules, which are subject to differing interpretations. The fair market value of our assets is expected to relate, in part, to (a) the market price of our ordinary 
shares and (b) the composition of our income and assets, which will be affected by how, and how quickly, we spend any cash that is raised in any financing 
transaction. Moreover, our ability to earn specific types of income that we currently treat as non-passive for purposes of the PFIC rules is uncertain with 
respect to future years. Based on our gross income, the average value of our assets, including goodwill and the nature of our active business, we do not 
expect to be treated as a PFIC for U.S. federal income tax purposes for the taxable year ended December 31, 2022. Because the value of our assets for 
purposes of determining PFIC status will depend in part on the market price of our ordinary shares, which may fluctuate significantly, there can be no 
assurance that we will not be considered a PFIC for our current taxable year ending December 31, 2023 or for any future taxable year.

If we are a PFIC, a U.S. Holder (defined below) would be subject to adverse U.S. federal income tax consequences, such as ineligibility for any preferred 
tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred, and additional reporting requirements 
under U.S. federal income tax laws and regulations. A U.S. Holder may in certain circumstances mitigate adverse tax consequences of the PFIC rules by 
filing an election to treat the PFIC as a qualified electing fund (“QEF”) or, if shares of the PFIC are “marketable stock” for purposes of the PFIC rules, by 
making a mark-to-market election with respect to the shares of the PFIC. If a U.S. Holder makes a mark-to-market election with respect to its ordinary 
shares, the U.S. Holder is required to include annually in its U.S. federal taxable income an amount reflecting any year end increase in the value of its 
ordinary shares. For purposes of this discussion, a “U.S. Holder” is a beneficial owner of ordinary shares that is for U.S. federal income tax purposes: (i) an 
individual who is a citizen or resident of the United States; (ii) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) 
created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (iii) an estate the income of which is subject to 
U.S. federal income taxation regardless of its source; or (iv) a trust (a) if a court within the U.S. can exercise primary supervision over its administration, 
and one or more U.S. persons have the authority to control all of the substantial decisions of that trust, or (b) that was in existence on August 20, 1996, and 
validly elected under applicable Treasury Regulations to continue to be treated as a domestic trust. 

Investors should consult their own tax advisors regarding all aspects of the application of the PFIC rules to the ordinary shares. 

Singapore taxes may differ from the tax laws of other jurisdictions. 

Prospective investors should consult their tax advisors concerning the overall tax consequences of purchasing, owning and disposing of our shares. 
Singapore tax law may differ from the tax laws of other jurisdictions, including the United States. 

We may become subject to unanticipated tax liabilities. 

We are incorporated under the laws of Singapore. We are, however, subject to income, withholding or other taxes in certain jurisdictions by reason of our 
activities and operations, and it is also possible that tax authorities in any such jurisdictions could assert that we are subject to greater taxation than we 
currently anticipate. Any such non-Singaporean tax liability could materially adversely affect our results of operations. 

Tax authorities could challenge the allocation of income and deductions among our subsidiaries, which could increase our overall tax liability. 

We are organized in Singapore, and we currently have subsidiaries in the United States, Japan, the United Kingdom, and Ireland. As we grow our business, 
we conduct, and expect to continue to conduct, increased operations through our subsidiaries in various jurisdictions. If two or more affiliated companies 
are located in different jurisdictions, the tax laws or regulations of each country generally will require transactions between those affiliated companies to be 
conducted on terms consistent with those between unrelated companies dealing at arms’ length, and appropriate documentation generally must be 
maintained to support the transfer prices. We maintain our transfer pricing policies to be compliant with applicable transfer pricing laws, but our transfer 
pricing procedures are not binding on applicable tax authorities. 

If tax authorities were to successfully challenge our transfer pricing, there could be an increase in our overall tax liability, which could adversely affect our 
financial condition, results of operations and cash flows. In addition, the tax laws in the jurisdictions in which we operate are subject to differing 
interpretations. Tax authorities may challenge our tax positions, and if successful, such challenges 

94

 
could increase our overall tax liability. In addition, the tax laws in the jurisdictions in which we operate are subject to change. We cannot predict the timing 
or content of such potential changes, and such changes could increase our overall tax liability, which could adversely affect our financial condition, results 
of operations and cash flows.

Our financial results reflect the effect of certain tax credits and the operation of certain tax regimes within the United Kingdom. Legislation in the 
United Kingdom will limit the amount we may be able to claim as a payable tax credit in the future which could impact our financial condition, results 
of operations and cash flows. 

As a company that carries out extensive research and development activities, we benefit from the U.K. research and development tax credit regime for 
small and medium sized companies, whereby our subsidiary in the United Kingdom is able to surrender the trading losses that arise from its research and 
development activities for a payable tax credit of up to 33.4% of eligible research and development expenditure on staff and consumables incurred on or 
before March 31, 2023 and generally up to 18.6% of such expenditure incurred on or after April 1, 2023. Expenditure of staff supplied by unconnected 
third parties incurred on or before March 31, 2023 are eligible for a cash rebate of up to 21.7% and generally up to 12.1% for such expenditure incurred on 
or after April 1, 2023.

Due to a change in the U.K. legislation affecting the U.K. research and development tax credit regime for small and medium sized companies, our ability to 
receive a payable tax credit for the surrender of our trading losses from research and development activities incurred from January 1, 2022 will be limited 
to the amount equal to three times our “pay as you earn” and U.K. national insurance tax liabilities, absent our qualification under an exception from such 
limitation.

Further, we may not be able to continue to claim a U.K. tax credit for research and development tax credits under the small and medium-sized companies 
regime in the future if we increase our personnel and expand our business because we may no longer qualify as a small or medium-sized enterprise.

Risks Related to Our Ordinary Shares 

The public market for our ordinary shares may not be liquid enough for our shareholders to sell their ordinary shares quickly or at market price, or at 
all. 

Our ordinary shares are currently listed for trading on the Nasdaq Global Market. There is no assurance that the trading market for our shares will be or 
remain active. Our shareholders may not be able to sell their ordinary shares quickly or at the market price, or at all. Our executive officers, our directors 
and their respective affiliates, and our other significant shareholders beneficially own a significant portion of our outstanding ordinary shares, and 
therefore, liquidity in our ordinary shares is limited. Due to the limited liquidity in our ordinary shares, relatively small orders can have a disproportionate 
impact on the trading price of our shares. Further, the limited liquidity in our ordinary shares may also impair our ability to raise capital by conducting 
offerings of our ordinary shares and may impair our ability to enter into strategic partnerships or acquire companies or products by using our ordinary 
shares as consideration. 

The market price of our ordinary shares is likely to be highly volatile, and our shareholders may lose some or all of their investment. 

The market price of our ordinary shares is likely to continue to be highly volatile, including in response to factors that are beyond our control. The stock 
market in general experiences extreme price and volume fluctuations. In particular, the market prices of securities of pharmaceutical and biotechnology 
companies are extremely volatile, and experience fluctuations that are often unrelated or disproportionate to the operating performance of these companies. 
These broad and sector-specific market fluctuations can result in extreme fluctuations in the price of our ordinary shares, regardless of our operating 
performance, and can cause our shareholders to lose some or all of their investment in us. 

We issued pre-funded warrants as part of our June 2022 financing, which may cause additional dilution to our shareholders. 

In June 2022, we closed an underwritten offering in which we issued and sold 25,464,483 ordinary shares and, to RA Capital Management, L.P. in lieu of 
additional ordinary shares, pre-funded warrants (“Pre-Funded Warrants”) to purchase up to 7,093,656 ordinary shares at an exercise price of $0.0001 per 
share. The Pre-Funded Warrants contain a so-called “blocker” provision which provides that they are only exercisable upon receipt of shareholder approval 
or if such exercise would not cause the aggregate number of ordinary shares or the combined voting power of total securities, in each case, beneficially 
owned by the holder (together with its affiliates) to exceed 19.99% of the number of ordinary shares or total securities, respectively, outstanding 
immediately after giving effect to the exercise. To the extent the Pre-Funded Warrants above are exercised, additional ordinary shares will be issued and 
such issuance would dilute existing shareholders and increase the number of shares eligible for resale in the public market.

95

 
Our principal shareholders and management own a significant percentage of our ordinary shares and will be able to exert significant control over 
matters subject to shareholder approval. 

Based on information publicly available to us as of December 31, 2022, our executive officers, our directors and their respective affiliates, and our other 
significant shareholders beneficially own a significant portion of our outstanding ordinary shares. As a result, these shareholders, if acting together, will 
continue to have significant influence over the outcome of corporate actions requiring shareholder approval, including the election of directors, any merger, 
consolidation or sale of all or substantially all of our assets and any other significant corporate transaction. The interests of these shareholders may not be 
the same as or may even conflict with the interests of our other shareholders. For example, these shareholders could delay or prevent a change of control of 
our company, even if such a change of control would benefit our other shareholders, which could deprive shareholders of an opportunity to receive a 
premium for their ordinary shares as part of a sale of our company or our assets and might affect the prevailing market price of our ordinary shares. The 
significant concentration of share ownership may adversely affect the trading price of our ordinary shares due to investors’ perception that conflicts of 
interest may exist or arise. 

We incur significant costs due to operating as a public company, and our management is required to devote substantial time to compliance initiatives. 

As a public company, we incur significant legal, accounting and other expenses. We are subject to the reporting and other requirements of the Exchange 
Act, the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), and the Dodd-Frank Wall Street Reform and Protection Act, as well as rules 
subsequently adopted by the SEC and the Nasdaq Stock Market. These rules and regulations require, among other things, that we file annual, quarterly and 
current reports with respect to our business and financial condition and establish and maintain effective disclosure and financial controls and corporate 
governance practices. We expect that compliance with these rules and regulations will continue to result in substantial legal and financial compliance costs 
and will make some activities more time-consuming and costly. Our management and other personnel devote a substantial amount of time to these 
compliance requirements. 

If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired, which 
could harm our operating results, our ability to operate our business and investors’ views of us.

We are required to comply with Section 404 of the Sarbanes-Oxley Act. Section 404 of the Sarbanes-Oxley Act requires public companies to maintain 
effective internal control over financial reporting. In particular, we must perform system and process evaluation and testing of our internal control over 
financial reporting to allow management to report on the effectiveness of our internal control over financial reporting. Ensuring that we have adequate 
internal financial and accounting controls and procedures in place so that we can produce accurate financial statements on a timely basis is a costly and 
time-consuming effort that is evaluated frequently. If we fail to maintain the effectiveness of our internal controls or fail to comply in a timely manner with 
the requirements of the Sarbanes-Oxley Act, or if we identify deficiencies in our internal control over financial reporting that are deemed to be material 
weaknesses, this could have a material adverse effect on our business. We could lose investor confidence in the accuracy and completeness of our financial 
reports, which could have an adverse effect on the price of our ordinary shares and we could be subject to sanctions or investigations by Nasdaq, the SEC 
or other regulatory authorities, which would require additional financial and management resources. In addition, if our efforts to comply with new or 
changed laws, regulations, and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, 
regulatory authorities may initiate legal proceedings against us and our business may be harmed.

The estimates and judgments we make, or the assumptions on which we rely, in preparing our consolidated financial statements could prove 
inaccurate. 

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). 
The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of our assets, 
liabilities, revenues and expenses, the amounts of charges accrued by us and related disclosure of contingent assets and liabilities. We base our estimates on 
historical experience and on various other assumptions that we believe to be reasonable under the circumstances. We cannot assure, however, that our 
estimates, or the assumptions underlying them, will not change over time or otherwise prove inaccurate. For example, our estimates as they relate to 
anticipated timelines and milestones for our clinical trials or preclinical development may prove to be inaccurate. If this is the case, we may be required to 
restate our consolidated financial statements, which could, in turn, subject us to securities class action litigation. Defending against such potential litigation 
relating to a restatement of our consolidated financial statements or otherwise would be expensive and would require significant attention and resources of 
our management. Moreover, our insurance to cover our obligations with respect to the ultimate resolution of any such litigation may be inadequate. As a 
result of these factors, any such potential litigation could have a material adverse effect on our financial results, harm our business, and cause our share 
price to decline.

96

 
We do not anticipate paying any cash dividends on our ordinary shares in the foreseeable future. 

We have never declared or paid cash dividends on our ordinary shares. We currently intend to retain all of our future earnings, if any, to finance the growth 
and development of our business, and we do not anticipate paying any cash dividends on our ordinary shares in the foreseeable future. In addition, the 
terms of any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our ordinary shares will be our 
shareholders’ sole source of gain for the foreseeable future. 

We may incur significant costs from class action litigation due to share volatility. 

Our share price may fluctuate for many reasons, including as a result of public announcements regarding the progress of our development efforts or the 
development efforts of our collaborators and/or competitors, the addition or departure of our key personnel, variations in our quarterly operating results and 
changes in market valuations of pharmaceutical and biotechnology companies. Holders of stock that has experienced significant price and trading volatility 
have occasionally brought securities class action litigation against the companies that issued the stock. If any of our shareholders were to bring a lawsuit of 
this type against us, even if the lawsuit is without merit, we could incur substantial costs defending the lawsuit. The lawsuit could also divert the time and 
attention of our management, which could harm our business. 

Sales of additional ordinary shares could cause the price of our ordinary shares to decline. 

Sales of substantial amounts of our ordinary shares in the public market, or the availability of such shares for sale, by us or others, including the issuance of 
ordinary shares upon exercise of outstanding options or Pre-Funded Warrants or vesting of outstanding restricted share units, or the perception that such 
sales could occur, could adversely affect the price of our ordinary shares. Certain of our shareholders have required us, or have the right to require us, to 
register the sales of their shares under the Securities Act under agreements between us and such shareholders. For example, in August 2019, we filed a 
registration statement on Form S-3, which was declared effective on August 14, 2019, to register the resale from time to time by certain of our executive 
officers, directors and their affiliates of up to approximately 7.1 million ordinary shares.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our share price and trading 
volume could decline. 

The trading market for our ordinary shares may depend in part on the research and reports that securities or industry analysts publish about us or our 
business. If too few securities or industry analysts cover our company, the trading price for our ordinary shares would likely be negatively impacted. If one 
or more of the analysts who cover us downgrade our ordinary shares or publish inaccurate or unfavorable research about our business, our share price 
would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our ordinary 
shares could decrease, which might cause our share price and trading volume to decline.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our financial statements and 
related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth 
elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business, includes forward-looking 
statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual 
Report on Form 10-K, our actual results could differ materially from the results described in, or implied by, these forward-looking statements.

Overview 

We are a clinical-stage genetic medicines company committed to delivering life-changing treatments for people battling devastating diseases. Using 
PRISM, our proprietary discovery and drug development platform that enables the precise design, optimization, and production of novel stereopure 
oligonucleotides, we are working to develop first-or best-in-class medicines that target the transcriptome (the full set of ribonucleic acid, or “RNA,” 
molecules produced from the human genome) to treat genetically defined diseases with a high degree of unmet need. 

Our RNA-targeting oligonucleotides are designed to correct disease-causing mutations, modulate protein activity, restore the production of functional 
proteins or reduce the expression of disease-promoting RNAs or proteins. Data from our ongoing clinical and preclinical studies has demonstrated 
significant improvements in potency, durability, and distribution for our oligonucleotides designed through PRISM, compared with competitor chemistries. 
These data support our platform as best-in-class for designing and optimizing RNA-targeting medicines. 

Since our inception, we have seen the value of developing RNA-targeting medicines compared to other nucleic acid therapeutics, including gene therapy 
and DNA editing. By intervening at the RNA level, we have the potential to address diseases that have historically been difficult to treat with small 
molecules or biologics, while retaining the ability to titrate dose, modulate duration of effect, and avoid risk of permanent off-target genetic changes and 
other challenges associated with DNA editing or gene therapy approaches. Oligonucleotides have additional advantages as a therapeutic class, including the 
ability to access multiple tissue types and the ability to modulate the frequency of dosing to ensure broad distribution within tissues over time. 
Oligonucleotides also have well-established manufacturing processes and validated test methods based on decades of improvements, as well as established 
regulatory, access, and reimbursement pathways.

Our approach is based on the scientific insight that the biological machinery necessary to address genetic diseases already exists in human cells and can be 
harnessed for therapeutic purposes with the right tools. We have built a versatile platform comprised of multiple therapeutic modalities, which provides 
flexibility to design built-for-purpose molecules that optimally address disease biology. These modalities are RNA base editing, splicing, and silencing, 
including both RNA interference (“RNAi”) and antisense, all of which incorporate proprietary and novel chemistries to optimize the pharmacological 
properties of our therapeutic oligonucleotides. 

100

 
 
 
 
We have a robust and diverse pipeline of potential first-or best-in-class programs. Our lead programs are designed to treat genetic diseases, including those 
in muscle, including Duchenne muscular dystrophy (“DMD”); liver, including alpha-1 antitrypsin deficiency (“AATD”); and the central nervous system 
(“CNS”), including Huntington’s disease (“HD”), amyotrophic lateral sclerosis (“ALS”) and frontotemporal dementia (“FTD”). These programs include:

- WVE-N531 (splicing), our exon 53 molecule for the treatment of DMD; 

- WVE-006 (editing), our SERPINA1 molecule for the treatment of AATD; 

- WVE-003 (silencing), our mHTT SNP3 molecule for the treatment of HD; and

- WVE-004 (silencing), our C9orf72 molecule for the treatment of C9orf72-associated ALS and FTD.

Over the last several years, we have built a leading RNA base editing capability. Our A-to-I RNA base editing oligonucleotides (“AIMers”) enable access 
to areas of disease biology that are not viable for other therapeutic modalities. Our editing capability affords us the dexterity to address both rare diseases, 
as well as diseases impacting large patient populations. 

AIMers are designed to target single bases on an RNA transcript and recruit proteins that exist in the body, called ADAR (adenosine deaminases acting on 
RNA) enzymes, which naturally possess the ability to change an adenine (A) to an inosine (I), which cells read as guanine (G). This approach enables both 
the correction of G-to-A point mutations, as well as the modulation of RNA to upregulate protein expression, modify protein-protein interactions, or alter 
RNA folding and processing. AIMers enable simplified delivery and avoid the risk of permanent changes to the genome and irreversible off-target effects 
with DNA-targeting approaches. AIMers are short in length, fully chemically modified, and use novel chemistry, including proprietary PN backbone 
modifications and chiral control, which make them distinct from other ADAR-mediated editing approaches. 

Our PRISM platform was built on the recognition that a significant opportunity exists to tune the pharmacological properties of oligonucleotide 
therapeutics by leveraging three key features of these molecules: sequence, chemistry, and stereochemistry. Our unique ability to control stereochemistry 
provides the resolution necessary to optimize pharmacological profiles and develop and manufacture stereopure oligonucleotides. Stereopure 
oligonucleotides are comprised of molecules with atoms precisely and purposefully arranged in three-dimensional orientations at each linkage. These differ 
from the mixture-based oligonucleotides currently on the market or in development by others. Additionally, to mitigate pharmacological risks and potential 
manufacturing challenges, our approach focuses on designing short, chemically modified oligonucleotides without the need for complex delivery vehicles. 
We have also established and continue to enhance our internal cGMP (current good manufacturing practices) manufacturing capabilities to increase control 
and visibility of our drug substance supply chain, while continuing to innovate oligonucleotide manufacturing.

PRISM also incorporates our novel, proprietary PN backbone chemistry modifications, which have been shown preclinically and clinically to increase 
potency, distribution, and durability of effect across our various modalities. PN chemistry is incorporated in all of our current clinical, preclinical and 
discovery-stage programs.

COVID-19 Business Update

We continue to closely monitor developments related to COVID-19, which was declared a pandemic by the World Health Organization on March 11, 2020. 
In response to this global pandemic, we have concentrated our efforts on the health and safety of our employees and patients, while maintaining business 
continuity and honoring our commitment to deliver life-changing treatments for people battling devastating diseases.

Our on-site activities continue with protocols for safely accessing and working within our facilities. While we continue to conduct research and 
development activities, including our ongoing clinical trials, the COVID-19 pandemic has impacted, and may continue to impact, certain of our early-stage 
discovery efforts and clinical trials. We are working with our clinical investigators, research and development vendors, and supply chain vendors to 
continually assess and take steps to mitigate the potential impact of COVID-19 on our manufacturing operations and research and development activities.

We will continue to closely monitor the COVID-19 situation as we evolve our business continuity plans. Given the global risks and uncertainties associated 
with COVID-19, our business, results of operations, and prospects have been and could be materially adversely affected. For additional information, see 
“Item 1A. Risk Factors” of this Annual Report on Form 10-K.

Recent Developments 

On December 13, 2022, Wave Life Sciences USA, Inc. and Wave Life Sciences UK Limited, entered into a Collaboration and License Agreement (the 
“GSK Collaboration Agreement”) with GlaxoSmithKline Intellectual Property (No. 3) (“GSK”), which became effective on January 27, 2023. Pursuant to 
the GSK Collaboration Agreement, we and GSK have agreed to collaborate on the research, development, and commercialization of oligonucleotide 
therapeutics, including an exclusive global license to WVE-006. The discovery collaboration has an initial four-year research term and combines our 
proprietary discovery and drug development platform, PRISM, with GSK’s unique insights from human genetics and its global development and 
commercial capabilities. 

Under the terms of the GSK Collaboration Agreement, we received an upfront payment of $170.0 million, which included a cash payment of $120.0 
million and a $50.0 million equity investment. On January 26, 2023, pursuant to a share purchase agreement we entered into with Glaxo Group Limited 
(“GGL”) dated as of December 13, 2022, we closed on the $50.0 million equity investment by selling 10,683,761 of our ordinary shares at a purchase price 
of $4.68 per share to GGL. Subsequent to the GSK Collaboration Agreement becoming effective on January 27, 2023, we received the upfront payment of 
$120.0 million and the first installment of research support funding in respect of target validation activities under the collaboration.

Financial Operations Overview

We have never been profitable, and since our inception, we have incurred significant operating losses. Our net loss was $161.8 million in 2022 and $122.2 
million in 2021. As of December 31, 2022 and 2021, we had an accumulated deficit of $967.3 million and $805.5 million, respectively. We expect to incur 
significant expenses and operating losses for the foreseeable future. 

Revenue

We recognize collaboration revenue under the Takeda Collaboration Agreement (as defined in Note 5 in the notes to the consolidated financial statements 
appearing elsewhere in this Annual Report on Form 10-K, “Note 5”), which became effective in April 2018. We have not generated any product revenue 
since our inception and do not expect to generate any revenue from the sale of products for the foreseeable future. 

Operating Expenses

Our operating expenses since inception have consisted primarily of research and development expenses and general and administrative expenses.

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our discovery efforts, and the development of 
our product candidates, which include:

•

•

•

•

•

•

•

compensation-related expenses, including employee salaries, bonuses, share-based compensation expense and other related benefits expenses 
for personnel in our research and development organization;

expenses incurred under agreements with third parties, including contract research organizations (“CROs”) that conduct research, preclinical 
and clinical activities on our behalf, as well as contract manufacturing organizations (“CMOs”) that manufacture drug product for use in our 
preclinical studies and clinical trials;

expenses incurred related to our internal manufacturing of drug substance for use in our preclinical studies and clinical trials; 

expenses related to compliance with regulatory requirements;

expenses related to third-party consultants;

research and development supplies and services expenses; and

facility-related expenses, including rent, maintenance and other general operating expenses.

We recognize research and development costs as incurred. We recognize external development costs based on an evaluation of the progress to completion 
of specific tasks using information provided to us by our vendors. Payments for these activities are based on the terms of the individual agreements, which 
may differ from the pattern of costs incurred, and are reflected in our financial statements as prepaid or accrued expenses.

102

 
Our primary research and development focus since inception has been the development of our proprietary discovery and drug development platform, 
PRISM. We are using PRISM, which includes our novel PN backbone chemistry modifications, to design, develop and commercialize a broad pipeline of 
nucleic acid therapeutic candidates that target RNA using RNA editing, splicing, and silencing. 

Our research and development expenses consist primarily of expenses related to our CROs, CMOs, consultants, other external vendors and fees paid to 
global regulatory agencies to conduct our clinical trials, in addition to compensation-related expenses, internal manufacturing expenses, facility-related 
expenses and other general operating expenses. These expenses are incurred in connection with research and development efforts and our preclinical 
studies and clinical trials. We track certain external expenses on a program-by-program basis. However, we do not allocate compensation-related expenses, 
internal manufacturing expenses, equipment repairs and maintenance expense, facility-related expenses or other operating expenses to specific programs. 
These expenses, which are not allocated on a program-by-program basis, are included in the “PRISM and other research and development expenses” 
category along with other external expenses related to our discovery and development programs, as well as platform development and identification of 
potential drug discovery candidates.

Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, 
primarily due to the increased size and duration of later-stage clinical trials. We expect to continue to incur significant research and development expenses 
in the foreseeable future as we continue to manage our existing clinical trials, initiate additional clinical trials for certain product candidates, pursue later 
stages of clinical development for certain product candidates, maintain our manufacturing capabilities and continue to discover and develop additional 
product candidates in multiple therapeutic areas. 

General and Administrative Expenses

General and administrative expenses consist primarily of compensation-related expenses, including salaries, bonuses, share-based compensation and other 
related benefits costs for personnel in our executive, finance, corporate, legal and administrative functions, as well as compensation-related expenses for 
our board of directors. General and administrative expenses also include legal fees; expenses associated with being a public company; professional fees for 
accounting, auditing, tax and consulting services; insurance costs; travel expenses; other operating costs; and facility-related expenses.

Other Income, Net

Other income, net is comprised of refundable tax credits from tax authorities, dividend and interest income earned on cash and cash equivalents balances, 
gains and losses on foreign currency transactions, and real estate taxes. We recognize refundable tax credits when there is reasonable assurance that we will 
comply with the requirements of the refundable tax credit and that the refundable tax credit will be received.

Income Taxes 

We are a Singapore multi-national company subject to taxation in the United States and various other jurisdictions. 

As of December 31, 2022 and 2021, we have recorded a full valuation allowance against our net operating loss carryforwards and federal and state tax 
credits in all jurisdictions due to uncertainty regarding future taxable income.

Revenue

Revenue for the years ended December 31, 2022 and 2021 was approximately $3.6 million and $41.0 million, respectively, and was primarily earned under 
the Takeda Collaboration Agreement. The $37.3 million decrease was primarily due to the amendment to our Takeda Collaboration Agreement in 2021, 
which discontinued the Category 2 component and resulted in the recognition of the previously constrained revenue and an additional $22.5 million for 
research and development services related to the Category 2 component. Furthermore, in 2022 there was an increase in the expected future research and 
development services under the Takeda Collaboration Agreement based on the revenue recognition standard.

•

•

an increase of $1.4 million in external expenses related to our ALS and FTD program, WVE-004 (PN-modified silencing oligonucleotide); 

a decrease of $15.7 million in external expenses related to our HD programs, driven by decreased external expenses related to our 
discontinued WVE-120101 and WVE-120102 programs, partially offset by continuing external expenses for our WVE-003 (PN-modified 
silencing oligonucleotide) program;

an increase of $1.5 million in external expenses related to our DMD programs, including WVE-N531 (PN-modified splicing 
oligonucleotide); 

an increase of $3.4 million in external expenses related to our AATD program, WVE-006 (PN-modified RNA editing oligonucleotide); and 

an increase of $3.3 million in internal and external research and development expenses that are not allocated on a program-by-program basis 
and are related to other discovery and development programs, including PRISM and the identification of potential drug discovery candidates, 
mainly due to increases in compensation-related expenses and facilities-related expenses, partially offset by decreases in other external 
research and development expenses. 

General and Administrative Expenses

General and administrative expenses were $50.5 million for the year ended December 31, 2022 compared to $46.1 million for the year ended December 31, 
2021. The increase of $4.4 million was primarily driven by increases in compensation-related expenses, as well as increases in other general and 
administrative operating expenses. 

Other Income, Net

Other income, net for the years ended December 31, 2022 and 2021 was $1.6 million and $4.6 million, respectively. The decrease of $3.0 million in other 
income, net was primarily driven by a decrease in estimated refundable tax credits, partially offset by an increase in dividend income during the year ended 
December 31, 2022.

Income Tax Benefit (Provision) 

During the years ended December 31, 2022 and 2021, we recorded income tax provision of $0.7 million and an income tax benefit of $0.2 million, 
respectively. The income tax provision for the year ended December 31, 2022 was primarily due to the requirement under the Tax Cuts and Jobs Act of 
2017 for taxpayers to capitalize and amortize research and development expenditures over five or fifteen years pursuant to Section 174 of the Internal 
Revenue Code of 1986, as amended, partially offset by the utilization of net operating losses subject to the Section 382 limitation. The income tax benefit 
for the year ended December 31, 2021 was primarily due to the release of a portion of our uncertain tax positions as a result of a lapse in the statute of 
limitations.

Liquidity and Capital Resources 

Since our inception, we have not generated any product revenue and have incurred recurring net losses. To date, we have primarily funded our operations 
through public and other registered offerings of our ordinary shares, collaborations with third parties and private placements of debt and equity securities. 
Through December 31, 2022, we have received an aggregate of approximately $1,021.2 million in net proceeds from these transactions, consisting of 
$630.9 million in net proceeds from public and other registered offerings of our ordinary shares, $301.0 million from our collaborations and $89.3 million 
in net proceeds from private placements of our debt and equity securities. 

As of December 31, 2022, we had cash and cash equivalents of $88.5 million, restricted cash of $3.7 million and an accumulated deficit of $967.3 million. 

Subsequent to December 31, 2022, we received $170.0 million in cash, of which $120.0 million was an upfront payment under the GSK Collaboration 
Agreement and $50.0 million was under the GSK Equity Investment. 

We expect that our existing cash and cash equivalents will be sufficient to fund our operations for at least the next twelve months. We have based this 
expectation on assumptions that may prove to be incorrect, and we may use our available capital resources sooner than we currently expect. In addition, we 
may elect to raise additional funds before we need them if the conditions for raising capital are favorable due to market conditions or strategic 
considerations, even if we expect we have sufficient funds for our current or future operating plans.

Our operating lease commitments as of December 31, 2022 total $47.0 million, of which $8.7 million is related to payments in 2023 and approximately 
$38.3 million is related to payments beyond 2023. 

Until we can generate significant revenue from product sales, if ever, we expect to continue to finance our operations through a combination of public or 
private equity or debt financings or other sources, which may include collaborations with third parties. In May 2019, we filed a shelf registration statement 
on Form S-3ASR with the SEC pursuant to which we registered for sale an indeterminate amount of any combination of our ordinary shares, debt 
securities, warrants, rights and/or units from time to time and at prices and on terms that we may determine. Our shelf registration statement on Form S-
3ASR also includes a prospectus covering up to an aggregate of $250.0 million in ordinary shares that we may issue and sell from time to time, through 
Jefferies LLC (“Jefferies”) acting as our sales agent, pursuant to the open market sales agreement that we entered into with Jefferies in May 2019, as 
amended in 

105

 
March 2020 and March 2022 (the “Sales Agreement”), for our “at-the-market” equity program. Since we no longer qualified as a “well-known seasoned 
issuer” at the time of the filing of our Annual Report on Form 10-K for the year ended December 31, 2019, we previously amended the shelf registration 
statement to register for sale up to $500.0 million of any combination of our ordinary shares, debt securities, warrants, rights and/or units from time to time 
and at prices and on terms that we may determine, including the $250.0 million in ordinary shares that we may issue and sell from time to time pursuant to 
our “at-the-market” equity program. This registration statement, which we refer to as the “2019 Form S-3,” remained effective until our 2022 Form S-3 (as 
defined below) was declared effective on May 4, 2022, after which time we may no longer offer or sell any securities under the 2019 Form S-3. During the 
year ended December 31, 2022, the Company sold 458,092 ordinary shares under its at-the-market equity program for aggregate net proceeds of $1.2 
million. 

On March 3, 2022, we filed a new universal shelf registration on Form S-3 with the SEC, which was declared effective by the SEC on May 4, 2022, 
pursuant to which we registered for sale up to $500.0 million of any combination of our ordinary shares, debt securities, warrants, rights and/or units from 
time to time and at prices and on terms that we may determine, which we refer to as the “2022 Form S-3.” The 2022 Form S-3 includes a prospectus 
covering up to approximately $132.0 million in ordinary shares that had not yet been issued or sold under our Sales Agreement with Jefferies. As of March 
22, 2023 we have $430.0 million in securities available for issuance under the 2022 Form S-3, including approximately $132.0 million in ordinary shares 
available for issuance under our at-the-market equity program.

Adequate additional financing may not be available to us on acceptable terms, or at all. Our inability to raise capital as and when needed would have a 
negative impact on our financial condition and our ability to pursue our business strategy. We will need to generate significant revenue to achieve 
profitability, and we may never do so.

Operating Activities

During 2022, operating activities used $127.8 million of cash, primarily due to our net loss of $161.8 million, partially offset by non-cash charges of $27.3 
million and changes in our operating assets and liabilities of $6.7 million. The non-cash charges for 2022 related mainly to share-based compensation 
expense of $17.2 million and depreciation expense of $6.6 million. The largest change in operating assets and liabilities was a $9.3 million increase in 
accounts payable. 

During 2021, operating activities used $89.0 million of cash, primarily due to our net loss of $122.2 million, offset by non-cash charges of $26.2 million, 
partially offset by changes in our operating assets and liabilities of $7.0 million. The non-cash charges for 2021 related mainly to share-based compensation 
expense of $16.4 million and depreciation expense of $7.5 million. The largest changes in operating assets and liabilities were a decrease of $30.0 million 
in accounts receivable and a decrease of $18.5 million in deferred revenue related to the Takeda Collaboration Agreement, as well as a decrease in accounts 
payable of approximately $6.6 million.

Investing Activities

During 2022, investing activities used $1.3 million of cash, primarily consisting of purchases of property and equipment. Additionally, we purchased $75.0 
million of short-term investments during 2022, all of which matured in 2022.

During 2021, investing activities used $0.6 million of cash, consisting of purchases of property and equipment.

Financing Activities

During 2022, net cash provided by financing activities was $67.2 million, primarily due to the $65.5 million in net proceeds from the underwritten offering 
we completed in June 2022, which was comprised of sales of ordinary shares and pre-funded warrants. Additionally, there were $1.1 million in net 
proceeds from our at-the-market equity program.

During 2021, net cash provided by financing activities was $55.8 million, which was mainly due to the approximately $55.0 million in net proceeds from 
our at-the-market equity program.

Funding Requirements

We expect to continue to incur significant expenses in connection with our ongoing research and development activities and our internal cGMP 
manufacturing activities. Furthermore, we anticipate that our expenses will continue to vary if and as we:

•

•

•

•

•

•

•

•

•

•

continue to conduct our clinical trials evaluating our product candidates in patients;

conduct research and preclinical development of discovery targets and advance additional programs into clinical development; 

file clinical trial applications with global regulatory agencies and conduct clinical trials for our programs; 

evaluate next steps for our programs in rare, inherited eye diseases;

make strategic investments in continuing to innovate our research and development platform, PRISM, and in optimizing our manufacturing 
processes and formulations;

maintain our manufacturing capabilities through our internal facility and our CMOs;

maintain our intellectual property portfolio and consider the acquisition of complementary intellectual property;

seek and obtain regulatory approvals for our product candidates; 

respond to the impacts of the COVID-19 global pandemic, the conflict involving Russia and Ukraine, global economic uncertainty, rising 
inflation, rising interest rates or market disruptions on our business; and

establish and build capabilities to market, distribute and sell our product candidates.

We may experience delays or encounter issues with any of the above, including but not limited to failed studies, complex results, safety issues or other 
regulatory challenges. 

Because of the numerous risks and uncertainties associated with the development of drug candidates and because the extent to which we may enter into 
collaborations with third parties for development of product candidates is unknown, we are unable to estimate the amounts of future capital outlays and 
operating expenses associated with completing the research and development for our therapeutic programs. Our future capital requirements for our 
therapeutic programs will depend on many factors, including:

•

•

•

•

•

•

•

•

•

•

•

the progress, results and costs of conducting research and continued preclinical and clinical development for our therapeutic programs and 
future potential pipeline candidates;

the number and characteristics of product candidates and programs that we pursue;

the cost of manufacturing clinical supplies of our product candidates;

whether and to what extent milestone events are achieved under our collaborations with Takeda and GSK or any potential future licensee or 
collaborator;

the costs, timing and outcome of regulatory review of our product candidates;

our ability to obtain marketing approval for our product candidates;

the impacts of the COVID-19 global pandemic, the conflict involving Russia and Ukraine, global economic uncertainty, rising inflation, 
rising interest rates or market disruptions on our business;

the costs and timing of future commercialization activities, including manufacturing, marketing, sales and distribution, for any of our product 
candidates for which we receive marketing approval;

market acceptance of our product candidates, to the extent any are approved for commercial sale, and the revenue, if any, received from 
commercial sales of our product candidates for which we receive marketing approval;

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and 
defending any intellectual property-related claims;

the effect of competing technological and market developments; and

107

 
•

the extent to which we acquire or invest in businesses, products and technologies, including entering into licensing or collaboration 
arrangements for product candidates.

Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that 
takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In 
addition, our product candidates, if approved, may not achieve commercial success. Our product revenue, if any, will be derived from sales of products that 
we do not expect to be commercially available for many years, if ever. Accordingly, we will need to obtain substantial additional funds to achieve our 
business objectives.

Adequate additional funds may not be available to us on acceptable terms when we need them, or at all. We do not currently have any committed external 
source of funds, except for possible future payments from Takeda or GSK under our collaborations with them. To the extent that we raise additional capital 
through the sale of equity or convertible debt securities, the ownership interest of our existing shareholders will be diluted, and the terms may include 
liquidation or other preferences that adversely affect the rights of our shareholders. Additional debt financing and preferred equity financing, if available, 
may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital 
expenditures or declaring dividends and may require the issuance of warrants, which could potentially dilute our shareholders’ ownership interests.

If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable 
rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we 
are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product 
development programs or any future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to 
develop and market ourselves.

Recently Issued and Adopted Accounting Pronouncements

For detailed information regarding recently issued and adopted accounting pronouncements and the expected impact on our consolidated financial 
statements, see Note 2 “Significant Accounting Policies” in the notes to the consolidated financial statements appearing elsewhere in this Annual Report on 
Form 10-K.

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. 
GAAP”). The preparation of our financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amount 
of assets, liabilities, revenue, costs and expenses and related disclosures. We believe that our revenue recognition policy, particularly (a) assessing the 
number of performance obligations; (b) determining the transaction price; (c) allocating the transaction price to the performance obligations in the contract; 
and (d) determining the pattern over which performance obligations are satisfied, including estimates to complete performance obligations, and the 
assumptions and estimates used in our analysis of contracts with CROs and CMOs to estimate the contract expense, involve a greater degree of judgment, 
and therefore we consider them to be our critical accounting policies. We evaluate our estimates and assumptions on an ongoing basis. Our actual results 
may differ from these estimates under different assumptions and conditions. 

Revenue Recognition

The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers 
(“ASC 606”). This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, 
insurance, and financial instruments. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an 
amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for 
arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five-step analysis: (i) identify the contract(s) 
with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the 
performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies 
the five-step analysis to contracts when it is probable that the entity will collect the consideration to which it is entitled in exchange for the goods or 
services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the 
goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is 
distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or 
as) the performance obligation is satisfied.

The Company has entered into collaboration agreements for research, development, and commercial services, under which the Company licenses certain 
rights to its product candidates to third parties. The terms of these arrangements typically include payment 

108

 
to the Company of one or more of the following: non-refundable, upfront license fees; reimbursement of certain costs; customer option exercise fees; 
development, regulatory and commercial milestone payments; and royalties on net sales of licensed products. Any variable consideration is constrained, 
and therefore, the cumulative revenue associated with this consideration is not recognized until it is deemed not to be at significant risk of reversal.

In determining the appropriate amount of revenue to be recognized as the Company fulfills its obligations under each of its agreements for which the 
collaboration partner is also a customer, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) 
determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) 
measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance 
obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. As part of the accounting for these 
arrangements, the Company must use significant judgment to determine: (a) the number of performance obligations based on the determination under step 
(ii) above; (b) the transaction price under step (iii) above; and (c) the timing of satisfaction of performance obligations as a measure of progress in step (v) 
above. The Company uses significant judgment to determine whether milestones or other variable consideration, except for royalties, should be included in 
the transaction price as described further below. The transaction price is allocated to the optional goods and services the Company expects to provide. The 
Company uses estimates to determine the timing of satisfaction of performance obligations. 

Amounts received prior to being recognized as revenue are recorded as deferred revenue. Amounts expected to be recognized as revenue within the 12 
months following the balance sheet date are classified as current portion of deferred revenue in the accompanying consolidated balance sheets. Amounts 
not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion.

Licenses of intellectual property: In assessing whether a promise or performance obligation is distinct from the other promises, the Company considers 
factors such as the research, development, manufacturing and commercialization capabilities of the customer and the availability of the associated expertise 
in the general marketplace. In addition, the Company considers whether the customer can benefit from a promise for its intended purpose without the 
receipt of the remaining promise, whether the value of the promise is dependent on the unsatisfied promise, whether there are other vendors that could 
provide the remaining promise, and whether it is separately identifiable from the remaining promise. For licenses that are combined with other promises, 
the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is 
satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. The Company 
evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Research and development services: If an arrangement is determined to contain a promise or obligation for the Company to perform research and 
development services, the Company must determine whether these services are distinct from other promises in the arrangement. In assessing whether the 
services are distinct from the other promises, the Company considers the capabilities of the customer to perform these same services. In addition, the 
Company considers whether the customer can benefit from a promise for its intended purpose without the receipt of the remaining promise, whether the 
value of the promise is dependent on the unsatisfied promise, whether there are other vendors that could provide the remaining promise, and whether it is 
separately identifiable from the remaining promise. For research and development services that are combined with other promises, the Company utilizes 
judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or 
at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. The Company evaluates the 
measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Customer options: If an arrangement is determined to contain customer options that allow the customer to acquire additional goods or services, the goods 
and services underlying the customer options are not considered to be performance obligations at the outset of the arrangement, as they are contingent upon 
option exercise. The Company evaluates the customer options for material rights, that is, the option to acquire additional goods or services for free or at a 
discount. If the customer options are determined to represent a material right, the material right is recognized as a separate performance obligation at the 
outset of the arrangement. The Company allocates the transaction price to material rights based on the standalone selling price. As a practical alternative to 
estimating the standalone selling price when the goods or services are both (i) similar to the original goods and services in the contract and (ii) provided in 
accordance with the terms of the original contract, the Company allocates the total amount of consideration expected to be received from the customer to 
the total goods or services expected to be provided to the customer. Amounts allocated to any material right are not recognized as revenue until the option 
is exercised and the performance obligation is satisfied.

109

 
Milestone payments: At the inception of each arrangement that includes milestone payments, the Company evaluates whether a significant reversal of 
cumulative revenue provided in conjunction with achieving the milestones is probable, and estimates the amount to be included in the transaction price 
using the most likely amount method. If it is probable that a significant reversal of cumulative revenue would not occur, the associated milestone value is 
included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not 
considered probable of being achieved until those approvals are received. For other milestones, the Company evaluates factors such as the scientific, 
clinical, regulatory, commercial, and other risks that must be overcome to achieve the particular milestone in making this assessment. There is considerable 
judgment involved in determining whether it is probable that a significant reversal of cumulative revenue would not occur. At the end of each subsequent 
reporting period, the Company reevaluates the probability of achievement of all milestones subject to constraint and, if necessary, adjusts its estimate of the 
overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of 
adjustment.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on a level of sales, and the license is deemed to be the 
predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the 
performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not 
recognized any royalty revenue resulting from any of its licensing arrangements.

Contract costs: The Company recognizes as an asset the incremental costs of obtaining a contract with a customer if the costs are expected to be recovered. 
As a practical expedient, the Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of 
the asset that it otherwise would have recognized is one year or less. To date, the Company has not incurred any incremental costs of obtaining a contract 
with a customer.

For additional discussion of accounting for collaboration revenues, see Note 5 of our consolidated financial statements. 

Prepaid and Accrued Research and Development Expenses

As we prepare our consolidated financial statements, we are required to estimate our prepaid and accrued expenses. For certain contracts with our CROs 
and CMOs, if the billing terms do not align with the pattern in which the work is completed by the CRO or CMO as of the end of the period, we are 
required to perform an analysis to estimate the expense, for the period and to date for each contract.

Contracts that are subject to this analysis generally relate to the following services: research and development services, manufacturing services, toxicology 
studies and clinical trial services. Once we have completed our analysis, we will record the estimated expense in the period for each contract and, 
depending on the invoicing activity related to each contract, we either have a prepayment or accrual as of the end of the period. We base our estimates on 
communications with internal study managers, our knowledge of the ongoing and past work at the CROs and CMOs, and communications and reporting 
from our CROs and CMOs, where applicable.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk 
exposure is primarily the result of fluctuations in interest rates and foreign exchange rates as well as, to a lesser extent, inflation and capital market risk.

Interest Rate Risk

We are exposed to interest rate risk in the ordinary course of our business. Our cash and cash equivalents are comprised of funds held in checking accounts 
and money market accounts. Our short-term investments were comprised of term deposits which had fixed interest rates. 

There were no short-term investments as of December 31, 2022 or 2021, as the $75.0 million of term deposits that constitute the Company’s short-term 
investments were purchased and all matured during the twelve months ended December 31, 2022.

Foreign Currency Risk

Due to our operations outside of the United States, we are exposed to market risk related to changes in foreign currency exchange rates. Historically, we 
have not hedged our foreign currency exposure. Changes in the relative values of currencies occur regularly and, in some instances, could materially 
adversely affect our business, our financial condition, our results of operations or our cash flows. For the years ended December 31, 2022 and 2021, 
changes in foreign currency exchange rates did not have a material impact on our historical financial position, our business, our financial condition, our 
results of operations or our cash flows.

A hypothetical 10% change in foreign currency rates would not have a material impact on our historical financial position or results of operations. 
However, there can be no assurance that changes in foreign currency exchange rates will not have a material adverse impact on us in the future.

Inflation Risk 

We do not believe that inflation had a material effect on our business, financial condition, results of operations, or cash flows in the last two years. If global 
inflation trends continue, we expect appreciable increases in clinical trial, labor, and other operating costs.

Capital Market Risk

We currently have no product revenues and depend on funds raised through other sources. One possible source of funding is through further equity 
offerings. Our ability to raise funds in this manner depends upon capital market forces affecting our share price, including impacts of the COVID-19 
pandemic and global economic uncertainty on the capital markets.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures 

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure 
controls and procedures as of December 31, 2022. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the 
Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the 
reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s 
rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be 
disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to its management, including its 
principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any 
controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management 
necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure 
controls and procedures as of December 31, 2022, our principal executive officer and principal financial officer concluded that, as of such date, our 
disclosure controls and procedures were effective at the reasonable assurance level. 

Changes in Internal Control over Financial Reporting 

There were no changes in our internal control over financial reporting identified in connection with the evaluation of such internal control required by Rule 
13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the fiscal quarter ended December 31, 2022 that have materially affected, or are 
reasonably likely to materially affect, our internal control over financial reporting. 

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting 
is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended, as a process designed by, or under the supervision of, 
the company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel to 
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance 
with generally accepted accounting principles and includes those policies and procedures that: 

•

•

•

Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of 
the company; 

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with 
generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of 
management and directors of the company; and 

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets 
that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of 
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate. 

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022. In making this assessment, 
management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-
Integrated Framework (2013).

Based on our assessment, management believes that, as of December 31, 2022, our internal control over financial reporting is effective based on those 
criteria.

As a “non-accelerated filer,” we are exempt from the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002. As a result, 
KPMG LLP, our independent registered public accounting firm, has not audited or issued an attestation report with respect to the effectiveness of our 
internal control over financial reporting as of December 31, 2022.

Item 9B. Other Information

Singapore Goods and Services Tax (“GST”) Rate

The Singapore GST rate was increased from 7% to 8% from January 1, 2023 and will be further increased to 9% from January 1, 2024. The issue or 
transfer of ownership of our ordinary shares would be exempt from GST, although the sale of our ordinary shares by a GST-registered investor may be 
considered to be a taxable supply subject to GST at 0% if certain conditions are met. Services consisting of arranging, brokering, underwriting or advising 
on the issue, allotment or transfer of ownership of our ordinary shares rendered by a GST-registered person to an investor belonging in Singapore for GST 
purposes in connection with the investor’s purchase, sale or holding of our ordinary shares will be subject to GST at the standard rate. Similar services 
rendered by a GST-registered person contractually to an investor belonging outside Singapore and for the direct benefit of an investor belonging outside 
Singapore or a GST-registered person in Singapore should generally, subject to the satisfaction of certain conditions, be subject to GST at 0%.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
Wave Life Sciences Ltd.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Wave Life Sciences Ltd. and subsidiaries (the Company) as of December 31, 2022 and 
2021, the related consolidated statements of operations and comprehensive loss, Series A preferred shares and shareholders’ equity (deficit), and cash flows 
for the years then ended, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements 
present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its 
cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these 
consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board 
(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not 
required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain 
an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal 
control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or 
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and 
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis 
for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be 
communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) 
involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

/s/ KPMG LLP

We have served as the Company’s auditor since 2015.

Wave Life Sciences Ltd.

Notes to Consolidated Financial Statements

1. THE COMPANY

Organization

Wave Life Sciences Ltd. (together with its subsidiaries, “Wave” or the “Company”) is a clinical-stage genetic medicines company committed to delivering 
life-changing treatments for people battling devastating diseases. Using PRISM, Wave’s proprietary discovery and drug development platform that enables 
the precise design, optimization, and production of novel stereopure oligonucleotides, Wave is working to develop best- or first-in-class medicines that 
target the transcriptome (the full set of ribonucleic acid (“RNA”) molecules produced from the human genome) to treat genetically defined diseases with a 
high degree of unmet need. 

The Company was incorporated in Singapore on July 23, 2012 and has its principal U.S. office in Cambridge, Massachusetts. The Company was 
incorporated with the purpose of combining two commonly held companies, Wave Life Sciences USA, Inc. (“Wave USA”), a Delaware corporation 
(formerly Ontorii, Inc.), and Wave Life Sciences Japan, Inc. (“Wave Japan”), a company organized under the laws of Japan (formerly Chiralgen., Ltd.), 
which occurred on September 13, 2012. On May 31, 2016, Wave Life Sciences Ireland Limited (“Wave Ireland”) was formed as a wholly-owned 
subsidiary of Wave Life Sciences Ltd. On April 3, 2017, Wave Life Sciences UK Limited (“Wave UK”) was formed as a wholly-owned subsidiary of Wave 
Life Sciences Ltd.

The Company’s primary activities since inception have been developing and evolving PRISM to design, develop and commercialize oligonucleotide 
therapeutics, advancing the Company’s differentiated portfolio, building the Company’s research, development and manufacturing capabilities, advancing 
programs into the clinic, furthering clinical development of such clinical-stage programs, building the Company’s intellectual property, and assuring 
adequate capital to support these activities.

Liquidity

Since its inception, the Company has not generated any product revenue and has incurred recurring net losses. To date, the Company has primarily funded 
its operations through private placements of debt and equity securities, public and other registered offerings of its equity securities and collaborations with 
third parties. Until the Company can generate significant revenue from product sales, if ever, the Company expects to continue to finance operations 
through a combination of public or private equity or debt financings or other sources, which may include collaborations with third parties. Adequate 
additional financing may not be available to the Company on acceptable terms, or at all. The inability to raise capital as and when needed would have a 
negative impact on the Company’s financial condition and ability to pursue its business strategy. 

As of December 31, 2022, the Company had cash and cash equivalents of $88.5 million. Subsequent to December 31, 2022, the Company received $170.0 
million in cash, of which $120.0 million was an upfront payment under the GSK Collaboration Agreement (as defined in note 14) and $50.0 million was 
the GSK Equity Investment (as defined in note 14). The Company expects that its existing cash and cash equivalents will be sufficient to fund its operations 
for at least the next twelve months. The Company has based this expectation on assumptions that may prove to be incorrect, and the Company may use its 
available capital resources sooner than it currently expects. If the Company’s anticipated operating results are not achieved in future periods, planned 
expenditures may need to be further reduced in order to extend the time period over which the then-available resources would be able to fund the 
Company’s operations. In addition, the Company may elect to raise additional funds before it needs them if the conditions for raising capital are favorable 
due to market conditions or strategic considerations, even if the Company expects it has sufficient funds for its current or future operating plans.

Risks and Uncertainties

The Company is subject to risks common to companies in the biotechnology industry including, but not limited to, new technological innovations, 
protection of proprietary technology, maintaining internal manufacturing capabilities, dependence on key personnel, compliance with government 
regulations and the need to obtain additional financing. The Company’s therapeutic programs will require significant additional research and development 
efforts, including extensive preclinical and clinical testing and regulatory approval, prior to commercialization of any product candidates. These efforts 
require significant amounts of additional capital, adequate personnel infrastructure and extensive compliance-reporting capabilities. There can be no 
assurance that the Company’s research and development efforts will be successful, that adequate protection for the Company’s intellectual property will be 
obtained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. 
Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate significant revenue from 
product sales. The Company operates in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology 
companies. 

F-6

 
 
Basis of Presentation

The Company has prepared the accompanying consolidated financial statements in conformity with generally accepted accounting principles in the United 
States (“U.S. GAAP”) and in U.S. dollars. 

2. SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

The Company considers all highly liquid securities with maturities of three months or less from the date of purchase to be cash equivalents. The Company's 
cash and cash equivalents are comprised of funds held in checking and money market accounts. 

Short-Term Investments 

The Company’s short-term investments consist of term deposits. 

Principles of Consolidation

The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and 
transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported 
amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported 
amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these consolidated financial statements include the 
assumptions used to determine the fair value of share-based awards, the Company’s revenue recognition policy, particularly, (a) assessing the number of 
performance obligations; (b) determining the transaction price; (c) allocating the transaction price to the performance obligations in the contract; and (d) 
determining the pattern over which performance obligations are satisfied, including estimates to complete performance obligations, the evaluation of 
progress to completion of external research and development costs which can result in prepaid or accrued expenses related to the Company’s contract 
research organizations (“CROs”) and contract manufacturing organizations (“CMOs”), the valuation allowance required for the Company’s deferred tax 
assets, determining uncertain tax positions and the related liabilities, and estimating refundable tax credits. Estimates are periodically reviewed in light of 
changes in circumstances, facts and experience. Actual results could differ from the Company’s estimates. 

Segment Data

The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The Company’s 
singular focus is on developing its proprietary discovery and drug development platform, PRISM, to develop and commercialize a broad pipeline of nucleic 
acid-based therapeutics, or oligonucleotides.

Going Concern

At each reporting period, the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue 
as a going concern within one year after the date that the financial statements are issued. The Company is required to make certain additional disclosures if 
the Company concludes substantial doubt exists and it is not alleviated by the Company’s plans or when the Company’s plans alleviate substantial doubt 
about the Company’s ability to continue as a going concern. The Company’s evaluation entails analyzing prospective operating budgets and forecasts for 
expectations of the Company’s cash needs and comparing those needs to the current cash and cash equivalent balance. 

Foreign Currency Translation

The functional currency is the U.S. dollar for all of the Company’s entities aside from Wave Japan, which has the Japanese Yen as its functional currency. 
Assets and liabilities of Wave Japan are translated at period end exchange rates while revenues and expenses of Wave Japan are translated at average 
exchange rates for the period. Net unrealized gains and losses from foreign currency translation are reflected as other comprehensive income (loss) within 
the consolidated statements of Series A preferred shares and shareholders’ equity (deficit) and the consolidated statements of operations and comprehensive 
loss. Gains and losses on foreign currency transactions are included in the consolidated statements of operations and comprehensive loss within other 
income, net.

F-7

 
Fair Value of Financial Instruments

The Company is required to disclose information on all assets and liabilities reported at fair value that enables an assessment of the inputs used in 
determining the reported fair values. The fair value hierarchy is a hierarchy of inputs used in measuring fair value that maximizes the use of observable 
inputs and minimizes the use of unobservable inputs by requiring that the observable inputs be used when available. Observable inputs are inputs that 
market participants would use in pricing the financial instrument based on market data obtained from sources independent of the Company. Unobservable 
inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the financial instrument and are 
developed based on the information available in the circumstances. The fair value hierarchy applies only to the valuation inputs used in determining the 
reported fair value of the investments and is not a measure of the investment credit quality. The hierarchy defines three levels of valuation inputs:

Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date of identical, unrestricted assets.

Level 2—Quoted prices for similar assets, or inputs that are observable, either directly or indirectly, for substantially the full term through 
corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions 
specific to the security.

Level 3—Pricing inputs are unobservable for the asset, that is, inputs that reflect the reporting entity’s own assumptions about the assumptions 
market participants would use in pricing the asset. Level 3 includes private investments that are supported by little or no market activity.

Cash, cash equivalents and restricted cash are Level 1 assets which are comprised of funds held in checking and money market accounts. Short-term 
investments are Level 2 assets which are comprised of term deposits. Cash, cash equivalents and restricted cash were recorded at fair value as of December 
31, 2022 and 2021, totaling $92.2 million and $154.2 million, respectively. There were no short-term investments as of December 31, 2022 or 2021, as the 
$75.0 million of term deposits that constitute the Company’s short-term investments were all purchased and reached maturity during the twelve months 
ended December 31, 2022. The carrying amounts of accounts payable and accrued expenses approximate their fair values due to their short-term maturities.

Concentration of Credit Risk

Cash, cash equivalents, restricted cash and short-term investments are financial instruments that potentially subject the Company to concentration of credit 
risk. The Company uses several financial institutions to maintain its cash, cash equivalents, restricted cash and short-term investments, all of which are 
high quality, accredited financial institutions and, accordingly, such funds are subject to minimal credit risk. The Company has not experienced any losses 
in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository 
institutions in which those deposits are held. The Company has no financial instruments with off-balance sheet risk of loss.

Restricted Cash

Restricted cash consists primarily of cash placed in separate restricted bank accounts as required under the terms of the Company’s lease agreements for its 
Cambridge, Massachusetts and Lexington, Massachusetts facilities (refer to Note 8). As of December 31, 2022 and 2021, the Company had $3.7 million of 
restricted cash, of which $2.7 million related to the Lexington facility and $1.0 million related to the Cambridge facility. 

Property and Equipment

Property and equipment, which consists primarily of equipment, furniture, software and leasehold improvements, are stated at cost less accumulated 
depreciation. Depreciation is calculated on a straight-line basis over the following estimated useful lives of the assets:

Equipment, Furniture and Software
Leasehold Improvements

3-7 years
Shorter of asset life or lease term 

Depreciation begins at the time the asset is placed in service. Maintenance and repairs are charged to operations as incurred. Upon retirement or sale, the 
cost of the disposed asset and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the 
consolidated statements of operations and comprehensive loss.

Impairment of Long-Lived Assets

Long-lived assets consist of property and equipment. Long-lived assets are reviewed for impairment whenever events or other changes in circumstances 
indicate that the carrying amount may not be recoverable. Certain factors may exist or events may occur that indicate 

F-8

 
 
 
that impairment exists including, but not limited to, the following: significant underperformance relative to historical or projected future operating results; 
significant changes in the manner of use of the underlying assets; and significant adverse industry or market economic trends.

When performing the impairment assessment for long-lived assets, the Company compares the carrying value of such assets to the estimated undiscounted 
future net cash flows expected from the use of the assets and their eventual disposition. In the event that the carrying value of the assets is determined to be 
unrecoverable, the Company would estimate the fair value of the assets and record an impairment charge for the excess of the carrying value over the fair 
value. 

Revenue Recognition

The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers 
(“ASC 606”). 

This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, and 
financial instruments. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that 
reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that 
an entity determines are within the scope of ASC 606, the entity performs the following five-step analysis: (i) identify the contract(s) with a customer; (ii) 
identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in 
the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step analysis to 
contracts when it is probable that the entity will collect the consideration to which it is entitled in exchange for the goods or services it transfers to the 
customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised 
within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then 
recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation 
is satisfied.

The Company has entered into collaboration agreements for research, development, and commercial services, under which the Company licenses certain 
rights to its product candidates to third parties. The terms of these arrangements typically include payment to the Company of one or more of the following: 
non-refundable, upfront license fees; reimbursement of certain costs; customer option exercise fees; development, regulatory and commercial milestone 
payments; and royalties on net sales of licensed products. Any variable consideration is constrained and, therefore, the cumulative revenue associated with 
this consideration is not recognized until it is deemed not to be at significant risk of reversal.

In determining the appropriate amount of revenue to be recognized as the Company fulfills its obligations under each of its agreements for which the 
collaboration partner is also a customer, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) 
determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) 
measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance 
obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. As part of the accounting for these 
arrangements, the Company must use significant judgment to determine: (a) the number of performance obligations based on the determination under step 
(ii) above; (b) the transaction price under step (iii) above; and (c) the timing of satisfaction of performance obligations as a measure of progress in step (v) 
above. The Company uses significant judgment to determine whether milestones or other variable consideration, except for royalties, should be included in 
the transaction price as described further below. The transaction price is allocated to the optional goods and services the Company expects to provide. The 
Company uses estimates to determine the timing of satisfaction of performance obligations. 

Amounts received prior to being recognized as revenue are recorded as deferred revenue. Amounts expected to be recognized as revenue within the 12 
months following the balance sheet date are classified as current portion of deferred revenue in the accompanying consolidated balance sheets. Amounts 
not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion.

Licenses of intellectual property: In assessing whether a promise or performance obligation is distinct from the other promises, the Company considers 
factors such as the research, development, manufacturing and commercialization capabilities of the customer and the availability of the associated expertise 
in the general marketplace. In addition, the Company considers whether the customer can benefit from a promise for its intended purpose without the 
receipt of the remaining promise, whether the value of the promise is dependent on the unsatisfied promise, whether there are other vendors that could 
provide the remaining promise, and whether it is separately identifiable from the remaining promise. For licenses that are combined with other promises, 
the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is 
satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing 

F-9

 
revenue. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue 
recognition.

Research and development services: If an arrangement is determined to contain a promise or obligation for the Company to perform research and 
development services, the Company must determine whether these services are distinct from other promises in the arrangement. In assessing whether the 
services are distinct from the other promises, the Company considers the capabilities of the customer to perform these same services. In addition, the 
Company considers whether the customer can benefit from a promise for its intended purpose without the receipt of the remaining promise, whether the 
value of the promise is dependent on the unsatisfied promise, whether there are other vendors that could provide the remaining promise, and whether it is 
separately identifiable from the remaining promise. For research and development services that are combined with other promises, the Company utilizes 
judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or 
at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. The Company evaluates the 
measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Customer options: If an arrangement is determined to contain customer options that allow the customer to acquire additional goods or services, the goods 
and services underlying the customer options are not considered to be performance obligations at the outset of the arrangement, as they are contingent upon 
option exercise. The Company evaluates the customer options for material rights, that is, the option to acquire additional goods or services for free or at a 
discount. If the customer options are determined to represent a material right, the material right is recognized as a separate performance obligation at the 
outset of the arrangement. The Company allocates the transaction price to material rights based on the standalone selling price. As a practical alternative to 
estimating the standalone selling price when the goods or services are both (i) similar to the original goods and services in the contract and (ii) provided in 
accordance with the terms of the original contract, the Company allocates the total amount of consideration expected to be received from the customer to 
the total goods or services expected to be provided to the customer. Amounts allocated to any material right are not recognized as revenue until the option 
is exercised and the performance obligation is satisfied.

Milestone payments: At the inception of each arrangement that includes milestone payments, the Company evaluates whether a significant reversal of 
cumulative revenue provided in conjunction with achieving the milestones is probable, and estimates the amount to be included in the transaction price 
using the most likely amount method. If it is probable that a significant reversal of cumulative revenue would not occur, the associated milestone value is 
included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not 
considered probable of being achieved until those approvals are received. For other milestones, the Company evaluates factors such as the scientific, 
clinical, regulatory, commercial, and other risks that must be overcome to achieve the particular milestone in making this assessment. There is considerable 
judgment involved in determining whether it is probable that a significant reversal of cumulative revenue would not occur. At the end of each subsequent 
reporting period, the Company reevaluates the probability of achievement of all milestones subject to constraint and, if necessary, adjusts its estimate of the 
overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of 
adjustment.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on a level of sales, and the license is deemed to be the 
predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the 
performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not 
recognized any royalty revenue resulting from any of its licensing arrangements.

Contract costs: The Company recognizes as an asset the incremental costs of obtaining a contract with a customer if the costs are expected to be recovered. 
As a practical expedient, the Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of 
the asset that it otherwise would have recognized is one year or less. To date, the Company has not incurred any incremental costs of obtaining a contract 
with a customer.

Research and Development Expenses

Research and development expenses are expensed as incurred. External development costs are recognized based on an evaluation of the progress to 
completion of specific tasks. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs 
incurred, and are reflected in the accompanying consolidated balance sheets as prepaid or accrued expenses. 

License Agreements and Patent Costs

Costs associated with licenses of technology and patent costs are expensed as incurred and are generally included in research and development expense in 
the consolidated statements of operations and comprehensive loss.

F-10

 
Refundable Tax Credits

The Company is eligible for refundable tax credits with tax authorities for certain qualified operating expenses. The Company recognizes refundable tax 
credits when there is reasonable assurance that the Company will comply with the requirements of the refundable tax credit and that the refundable tax 
credit will be received. Refundable tax credits are recorded as income and classified in other income, net in the consolidated statements of operations and 
comprehensive loss. 

Net Loss per Share

Basic net loss per share is computed using the weighted-average number of ordinary shares outstanding during the period. The outstanding Pre-Funded 
Warrants (as defined in note 6) are included in the weighted-average number of ordinary shares outstanding used in the calculation of basic net loss per 
share as the exercise price is negligible and the warrants are fully vested and exercisable. Diluted net loss per share is computed using the sum of the 
weighted-average number of ordinary shares outstanding during the period and, if dilutive, the weighted-average number of potential ordinary shares, 
including the assumed exercise of share options and the assumed vesting of RSUs (as defined in note 7).

The Company applies the two-class method to calculate its basic and diluted net loss per share attributable to ordinary shareholders, as its Series A 
preferred shares are participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to 
earnings that otherwise would have been available to ordinary shareholders. However, for the periods presented, the two-class method does not impact the 
net loss per ordinary share as the Company was in a net loss position for each of the periods presented and holders of Series A preferred shares do not 
participate in losses.

The Company’s Series A preferred shares contractually entitle the holders of such shares to participate in dividends but do not contractually require the 
holders of such shares to participate in losses of the Company. Accordingly, for periods in which the Company reports a net loss attributable to ordinary 
shareholders, diluted net loss per share attributable to ordinary shareholders is the same as basic net loss per share attributable to ordinary shareholders, 
since dilutive ordinary shares are not assumed to have been issued if their effect is anti-dilutive.

Share-Based Compensation

The Company measures and recognizes share-based compensation expense, for both employee and director option awards, based on the grant date fair 
value of the awards. The Company calculates the fair value of restricted share unit awards based on the grant date fair value of the underlying ordinary 
shares. The Company determines the fair value of share-based awards granted to non-employees as either the fair value of the consideration received or the 
fair value of the equity instruments issued, whichever is more reliably measurable. Equity instruments issued to non-employees as consideration for goods 
or services received by the Company have been accounted for based on the fair value of the equity instruments issued. The Company recognizes share-
based compensation expense on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. The Company 
accounts for forfeitures as they occur.

The Company classifies share-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in 
which the award recipient’s compensation costs are classified or in which the award recipient’s service payments are classified. 

The fair value of each share option grant was determined using the methods and assumptions discussed below. These inputs are generally subjective and 
require significant judgment and estimation by management.

•

•

•

Fair Value of Ordinary Shares  The fair value of the ordinary shares underlying the Company’s share-based awards is based on the closing 
price of the Company’s ordinary shares as reported by the Nasdaq Global Market on the date of grant.

Expected Term  The expected term of share options represents the weighted-average period that the share options are expected to remain 
outstanding. The Company estimated the expected term using the simplified method, which is an average of the contractual term of the 
option and the vesting period.

Expected Volatility  Since there was limited historical data for the Company’s ordinary shares and limited company-specific historical 
volatility through the third quarter of 2021, the Company determined the share price volatility for options granted based on an analysis of the 
volatility used by a peer group of publicly traded companies. In evaluating similarity, the Company considers factors such as industry, stage 
of life cycle and size. Beginning in the fourth quarter of 2021, the Company had sufficient historical volatility data for its ordinary shares and 
as such no longer relies on an analysis of the volatility from a peer group to calculate expected volatility. 

F-11

Risk-free Interest Rate  The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for zero-coupon U.S. 
Treasury notes with remaining terms similar to the expected term of the options.

Dividend Rate  The expected dividend was assumed to be zero as the Company has never paid dividends and has no current plans to do so. 

Income Taxes

The Company accounts for income taxes using an asset and liability approach, which requires recognition of deferred tax assets and liabilities for the 
expected future tax consequences of events that have been recognized in the consolidated financial statements but have not been reflected in taxable 
income. A valuation allowance is established to reduce deferred tax assets to their estimated realizable value. Therefore, the Company provides a valuation 
allowance to the extent that it is more likely than not that all or a portion of the deferred tax assets will not be realized in the future.

The Company accounts for uncertainty in income taxes recognized in the financial statements by applying a two-step process to determine the amount of 
tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the 
tax authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to 
recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of 
being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that 
are considered appropriate as well as the related net interest and penalties. The Company recognizes interest and penalties related to uncertain tax positions 
in the income tax provision on the consolidated statements of operations and comprehensive loss. 

The Company has certain service arrangements in place between its U.S., Japan, U.K. and Singapore entities, which include transfer pricing assumptions. 
The determination of the appropriate level of transfer pricing requires judgment based on transfer pricing analyses of comparable companies. The Company 
monitors the nature of its service arrangements for changes in its operations as well as economic conditions. The Company also periodically reviews the 
transfer pricing analyses for changes in the composition in the pool of comparable companies as well as the related ongoing results of the comparable 
companies.

Leases

The Company accounts for leases in accordance with ASC Topic 842, Leases (“ASC 842”). At the inception of an arrangement, the Company determines 
whether the arrangement is or contains a lease based on the unique facts and circumstances present in the arrangement. Most leases with a term greater than 
one year are recognized on the balance sheet as right-of-use assets and short-term and long-term lease liabilities, as applicable. The Company typically only 
includes an initial lease term in its assessment of a lease arrangement. Options to renew a lease are not included in the Company’s assessment unless there 
is reasonable certainty that the Company will renew the lease. The Company monitors its plans to renew its leases on a quarterly basis.

Certain lease agreements include rental payments that are adjusted periodically for inflation or other variables. In addition to rent, the leases may require 
the Company to pay additional amounts for taxes, insurance, maintenance, or other expenses, which are generally referred to as non-lease components. 
Such adjustments to rental payments and variable non-lease components are treated as variable lease payments and recognized in the period in which the 
obligation for these payments are incurred. Variable lease components and variable non-lease components are not measured as part of the right-of-use asset 
and lease liability. Only when lease components and their associated non-lease components are fixed are they accounted for as a single lease component 
and are recognized as part of a right-of-use asset and lease liability. Total contract consideration is allocated to the combined fixed lease and non-lease 
component. This policy election applies consistently to all asset classes under lease agreements.

Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected 
remaining lease term. Certain adjustments to the right-of-use asset may be required for items such as incentives received. The interest rate implicit in lease 
contracts is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rate, which reflects the fixed rate at which the 
Company could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic 
environment.

Accounting Pronouncements

There were no recently issued or adopted accounting pronouncements that would have a material impact on the Company's consolidated financial 
statements.

5. COLLABORATION AGREEMENTS

Takeda Collaboration and Equity Agreements

In February 2018, Wave USA and Wave UK entered into a global strategic collaboration (the “Takeda Collaboration”) with Takeda Pharmaceutical 
Company Limited (“Takeda”), pursuant to which Wave USA, Wave UK and Takeda agreed to collaborate on the research, development and 
commercialization of oligonucleotide therapeutics for disorders of the Central Nervous System (“CNS”). The Takeda Collaboration provides the Company 
with at least $230.0 million in committed cash and Takeda with the option to co-develop and co-commercialize the Company’s CNS development programs 
in (1) Huntington’s disease (“HD”); (2) amyotrophic lateral sclerosis (“ALS”) and frontotemporal dementia (“FTD”); and (3) the Company’s discovery-
stage program targeting ATXN3 for the treatment of spinocerebellar ataxia 3 (“SCA3”) (collectively, “Category 1 Programs”). In addition, the Takeda 
Collaboration provided Takeda the right to exclusively license multiple preclinical programs for CNS disorders, including Alzheimer’s disease and 
Parkinson’s disease (collectively, “Category 2 Programs”). In April 2018, the Takeda Collaboration became effective and Takeda paid the Company $110.0 
million as an upfront payment. Takeda also agreed to fund the Company’s research and preclinical activities in the amount of $60.0 million during the four-
year research term and to reimburse the Company for any collaboration-budgeted research and preclinical expenses incurred by Wave that exceed that 
amount.

Simultaneously with Wave USA and Wave UK’s entry into the collaboration and license agreement with Takeda (the “Takeda Collaboration Agreement”), 
the Company entered into a share purchase agreement with Takeda (the “Takeda Equity Agreement,” and together with the Takeda Collaboration 
Agreement, the “Takeda Agreements”) pursuant to which it agreed to sell to Takeda 1,096,892 of its ordinary shares at a purchase price of $54.70 per share. 
In April 2018, the Company closed the Takeda Equity Agreement and received aggregate cash proceeds of $60.0 million. The Company did not incur any 
material costs in connection with the issuance of shares.

With respect to Category 1 Programs, the Company will be responsible for researching and developing products and companion diagnostics for Category 1 
Programs through completion of the first proof of mechanism study for such products. Takeda will have an exclusive option for each target and all 
associated products and companion diagnostics for such target, which it may exercise at any time through completion of the proof of mechanism study. If 
Takeda exercises this option, the Company will receive an opt-in payment and will lead manufacturing and joint clinical co-development activities and 
Takeda will lead joint co-commercial activities

in the United States and all commercial activities outside of the United States. Global costs and potential profits will be shared 50:50 and the Company will 
be eligible to receive development and commercial milestone payments. In addition to its 50% profit share, the Company is eligible to receive option 
exercise fees and development and commercial milestone payments for each of the Category 1 Programs.

With respect to Category 2 Programs, the Company granted Takeda the right to exclusively license multiple preclinical programs during a four-year 
research term (subject to limited extension for programs that were initiated prior to the expiration of the research term, in accordance with the Takeda 
Collaboration Agreement) (“Category 2 Research Term”). During that term, the Takeda Collaboration provided that the parties may collaborate on 
preclinical programs for up to six targets at any one time. The Company was responsible for researching and preclinically developing products and 
companion diagnostics directed to the agreed upon targets through completion of Investigational New Drug application (“IND”)-enabling studies in the 
first major market country. Thereafter, Takeda would have an exclusive worldwide license to develop and commercialize products and companion 
diagnostics directed to such targets, subject to the Company’s retained rights to lead manufacturing activities for products directed to such targets. Takeda 
agreed to fund the Company’s research and preclinical activities in the amount of $60.0 million during the research term and reimburse the Company for 
any collaboration-budgeted research and preclinical expenses incurred by the Company that exceeded that amount. The Company was also eligible to 
receive tiered high single-digit to mid-teen royalties on Takeda’s global commercial sales of products from each Category 2 Program. 

Under the Takeda Collaboration Agreement, each party granted to the other party specific intellectual property licenses to enable the other party to perform 
its obligations and exercise its rights under the Takeda Collaboration Agreement, including license grants to enable each party to conduct research, 
development and commercialization activities pursuant to the terms of the Takeda Collaboration Agreement.

The term of the Takeda Collaboration Agreement commenced on April 2, 2018 and, unless terminated earlier, will continue until the date on which: (i) with 
respect to each Category 1 Program target for which Takeda does not exercise its option, the expiration or termination of the development program with 
respect to such target; (ii) with respect to each Category 1 Program target for which Takeda exercises its option, the date on which neither party is 
researching, developing or manufacturing any products or companion diagnostics directed to such target; or (iii) with respect to each Category 2 Program 
target, the date on which royalties are no longer payable with respect to products directed to such target.

Takeda may terminate the Takeda Collaboration Agreement for convenience on 180 days’ notice, in its entirety or on a target-by-target basis. Subject to 
certain exceptions, each party has the right to terminate the Takeda Collaboration Agreement on a target-by-target basis if the other party, or a third party 
related to such party, challenges the patentability, enforceability or validity of any patents within the licensed technology that cover any product or 
companion diagnostic that is subject to the Takeda Collaboration Agreement. In the event of any material breach of the Takeda Collaboration Agreement by 
a party, subject to cure rights, the other party may terminate the Takeda Collaboration Agreement in its entirety if the breach relates to all targets or on a 
target-by-target basis if the breach relates to a specific target. In the event that Takeda and its affiliates cease development, manufacturing and 
commercialization activities with respect to compounds or products subject to the Takeda Collaboration Agreement and directed to a particular target, the 
Company may terminate the Takeda Collaboration Agreement with respect to such target. Either party may terminate the Takeda Collaboration Agreement 
for the other party’s insolvency. In certain termination circumstances, the Company would receive a license from Takeda to continue researching, 
developing and manufacturing certain products, and companion diagnostics.

The Takeda Collaboration is managed by a joint steering committee in which both parties are represented equally. The joint steering committee is tasked 
with overseeing the scientific progression of each Category 1 Program and, prior to the Amendment (discussed below), the Category 2 Programs.

The Company assessed this arrangement in accordance with ASC 606 and concluded that the contract counterparty, Takeda, is a customer for Category 1 
Programs prior to Takeda exercising its option, and for Category 2 Programs during the Category 2 Research Term. The Company identified the following 
material promises under the arrangement: (1) the non-exclusive, royalty-free research and development license for each Category 1 Program; (2) the 
research and development services for each Category 1 Program through completion of the first proof of mechanism study; (3) the exclusive option to 
license, co-develop and co-commercialize each Category 1 Program; (4) the right to exclusively license the Category 2 Programs; and (5) the research and 
preclinical development services of the Category 2 Programs through completion of IND-enabling studies. The research and development services for each 
Category 1 Program were determined to not be distinct from the research and development license and should therefore be combined into a single 
performance obligation for each Category 1 Program. The research and preclinical development services for the Category 

F-14

 
2 Programs were determined to not be distinct from the exclusive licenses for the Category 2 Programs and should therefore were combined into a single 
performance obligation.

Additionally, the Company determined that the exclusive option for each Category 1 Program was priced at a discount and, as such, provide material rights 
to Takeda, representing three separate performance obligations. Based on these assessments, the Company identified seven performance obligations in the 
Takeda Collaboration Agreement: (1) research and development services through completion of the first proof of mechanism and non-exclusive research 
and development license for HD; (2) research and development services through completion of the first proof of mechanism and non-exclusive research 
and development license for ALS and FTD; (3) research and development services through completion of the first proof of mechanism and non-exclusive 
research and development license for SCA3; (4) the material right provided for the exclusive option to license, co-develop and co-commercialize HD; (5) 
the material right provided for the exclusive option to license, co-develop and co-commercialize ALS and FTD; (6) the material right provided for the 
exclusive option to license, co-develop and co-commercialize SCA3; and (7) the research and preclinical development services and right to exclusively 
license the Category 2 Programs.

At the outset of the arrangement, the transaction price included the $110.0 million upfront consideration received and the $60.0 million of committed 
research and preclinical funding for the Category 2 Programs. The Company determined that the Takeda Collaboration Agreement did not contain a 
significant financing component. The option exercise fees to license, co-develop and co-commercialize each Category 1 Program that may be received are 
excluded from the transaction price until each customer option is exercised. The potential milestone payments were excluded from the transaction price, as 
all milestone amounts were fully constrained at the inception of the Takeda Collaboration Agreement. The Company will reevaluate the transaction price at 
the end of each reporting period and, as uncertain events are resolved or other changes in circumstances occur, if necessary, will adjust its estimate of the 
transaction price.

The Company allocated the transaction price to the performance obligations on a relative standalone selling price basis. For the performance obligations 
associated with the research and development services through completion of the first proof of mechanism and non-exclusive research and development 
license for HD; the research and development services through completion of the first proof of mechanism and non-exclusive research and development 
license for ALS and FTD; the research and development services through completion of the first proof of mechanism and non-exclusive research and 
development license for SCA3; and the research and preclinical development services and right to exclusively license the Category 2 Programs, the 
Company determined the standalone selling price using estimates of the costs to perform the research and development services, including expected 
internal and external costs for services and supplies, adjusted to reflect a profit margin. The total estimated cost of the research and development services 
reflected the nature of the services to be performed and the Company’s best estimate of the length of time required to perform the services. For the 
performance obligations associated with the material right provided for the exclusive option to license, co-develop and co-commercialize HD; the material 
right provided for the exclusive option to license, co-develop and co-commercialize ALS and FTD; and the material right provided for the exclusive option 
to license, co-develop and co-commercialize SCA3, the Company estimated the standalone fair value of the option to license each Category 1 Program 
utilizing an adjusted market assessment approach, and determined that any standalone fair value in excess of the amounts to be paid by Takeda associated 
with each option represented a material right.

Revenue associated with the research and development services for each Category 1 Program performance obligation is being recognized as the research 
and development services are provided using an input method, according to the costs incurred on each Category 1 Program and the total costs expected to 
be incurred to satisfy each Category 1 Program performance obligation. Prior to the Amendment described below, revenue associated with the research and 
preclinical development services for the Category 2 Programs performance obligation was recognized as the research and preclinical development services 
that were provided using an input method, according to the costs incurred on Category 2 Programs and the total costs expected to be incurred to satisfy the 
performance obligation. The amount allocated to the material right for each Category 1 Program option will be recognized on the date that Takeda exercises 
each respective option, or immediately as each option expires unexercised. The amounts received that have not yet been recognized as revenue are recorded 
in deferred revenue on the Company’s consolidated balance sheet. 

On October 15, 2021, Wave USA, Wave UK and Takeda entered into the Second Amendment to the Takeda Collaboration Agreement (the “Amendment”), 
which discontinued the Category 2 component of the Takeda Collaboration. The Category 1 Programs under the Collaboration Agreement remain in effect 
and are unchanged by the Amendment. Pursuant to the Amendment, Takeda agreed to pay the Company an additional $22.5 million as full payment for 
reimbursable Category 2 Programs collaboration-budgeted research and preclinical expenses. The Company received this payment from Takeda related to 
the Category 2 component and recognized the full amount as collaboration revenue in the year ended December 31, 2021. During the year ended December 
31, 2021, in addition to the revenue recognized related to the Amendment, the Company recognized another $18.5 million of collaboration revenue related 
to services pertaining to the Category 1 Programs and Category 2 Programs. 

F-15

 
During the years ended December 31, 2022 and 2021, the Company recognized revenue of approximately $3.3 million and $41.0 million, respectively, 
under the Takeda Collaboration Agreement in the Company’s consolidated statements of operations and comprehensive loss. Through December 31, 2022, 
the Company had recognized revenue of $81.2 million under the Takeda Collaboration Agreement as collaboration revenue in the Company’s consolidated 
statements of operations and comprehensive loss.

The aggregate amount of the transaction price allocated to the Company’s unsatisfied and partially unsatisfied performance obligations and recorded in 
deferred revenue as of December 31, 2022 and 2021, was $111.3 million and $114.6 million, respectively. The deferred revenue included in current 
liabilities as of December 31, 2022 and 2021, was approximately $31.6 million and $37.1 million, respectively. The deferred revenue included in long-term 
liabilities as of December 31, 2022 and 2021, was $79.8 million and approximately $77.5 million, respectively. The increase in the long-term portion of 
deferred revenue was due to an increase in the period over which certain Category 1 Program performance obligations are expected to be satisfied, which 
led to a corresponding decrease to the current portion of deferred revenue as of December 31, 2022. Additionally, the current portion of deferred revenue 
decreased from December 31, 2021 to December 31, 2022 due to revenue recognized during the year ended December 31, 2022. The Company expects to 
recognize revenue for the portion of the deferred revenue that relates to the research and development services for each Category 1 Program as costs are 
incurred over the remaining research term. The Company expects to recognize revenue for the portion of the deferred revenue that relates to the material 
right for each Category 1 Program option upon Takeda’s exercise of such option, or immediately as each option expires unexercised. 

6. SHARE CAPITAL

The following represents the Company’s financing transactions during the years ended December 31, 2022 and 2021:

•

•

The Company entered into an open market sales agreement with Jefferies LLC in May 2019, as amended in March 2020 and March 2022, for its 
at-the-market equity program. During the year ended December 31, 2021, the Company sold 10,740,915 ordinary shares under its at-the-market 
equity program for aggregate net proceeds of $54.9 million after deducting commissions and offering expenses. During the year ended December 
31, 2022, the Company sold 458,092 ordinary shares under its at-the-market equity program for aggregate net proceeds of $1.2 million after 
deducting commissions and offering expenses. 

On June 16, 2022, the Company closed an underwritten offering (the “June 2022 Offering”) in which the Company issued and sold 25,464,483 
of the Company’s ordinary shares at a price of $2.15 per share and pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 7,093,656 
of the Company’s ordinary shares at an offering price of $2.1499 per Pre-Funded Warrant, which represents the per share offering price for the 
ordinary shares less the $0.0001 per share exercise price for each Pre-Funded Warrant. These Pre-Funded Warrants were recorded as a 
component of shareholders’ equity within additional paid-in capital. The gross proceeds to the Company from the June 2022 Offering were $70.0 
million before deducting underwriting discounts and commissions and other offering expenses. The net proceeds to the Company from the June 
2022 Offering were approximately $65.5 million after deducting underwriting commissions and offering expenses. The Pre-Funded Warrants are 
exercisable at any time after their original issuance and on or prior to the five-year anniversary of the original issuance date. A holder of Pre-
Funded Warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than 19.99% of the number 
of the Company’s ordinary shares outstanding or more than 19.99% of the combined voting power of the Company’s securities outstanding 
immediately after giving effect to such exercise, unless and until shareholder approval is obtained. 

Features of the Series A Preferred Shares and Ordinary Shares

The Series A preferred shares and ordinary shares have no par value and there is no concept of authorized share capital under Singapore law. The Series A 
preferred shares are not redeemable and have no entitlement to dividends.

Voting

The holders of Series A preferred shares are not entitled to vote on any of the matters proposed to shareholders, other than as specified in the Company's 
Constitution. The holders of ordinary shares are entitled to one vote for each ordinary share held at all meetings of shareholders and written actions in lieu 
of meetings. 

Dividends

All dividends, if any, shall be declared and paid pro rata according to the number of ordinary shares held by each member entitled to receive dividends. The 
Company’s board of directors may deduct from any dividend all sums of money presently payable by the member to the Company on account of calls. 

F-16

 
Liquidation

In the event of a liquidation, dissolution or winding up of, or a return of capital by the Company, the ordinary shares will rank equally with the Series A 
preferred shares after the payment of the liquidation preference of an aggregate of approximately $10 thousand for Series A preferred shares.

7. SHARE-BASED COMPENSATION

The Wave Life Sciences Ltd. 2021 Equity Incentive Plan (the “2021 Plan”) was approved by the Company’s shareholders and went into effect on August 
10, 2021. The 2021 Plan serves as the successor to the Wave Life Sciences Ltd. 2014 Equity Incentive Plan, as amended (the “2014 Plan”), such that 
outstanding awards granted under the 2014 Plan continue to be governed by the terms of the 2014 Plan, but no awards may be made under the 2014 Plan 
after August 10, 2021. The aggregate number of ordinary shares authorized for issuance of awards under the 2021 Plan was originally 5,450,000 ordinary 
shares, and was subsequently increased to 11,450,000 in August 2022, plus the number of ordinary shares underlying any awards under the 2014 Plan that 
are forfeited, cancelled or otherwise terminated (other than by exercise or withheld by the Company to satisfy any tax withholding obligation) on or after 
August 10, 2021. 

The 2021 Plan authorizes (and the 2014 Plan previously authorized) the board of directors or a committee of the board of directors to, among other things, 
grant non-qualified share options, restricted awards, which include restricted shares and restricted share units (“RSUs”), and performance awards to eligible 
employees and directors of the Company. The Company accounts for grants to its board of directors as grants to employees.

As of December 31, 2022, 6,339,480 ordinary shares remained available for future grant under the 2021 Plan. In accordance with Nasdaq Listing Rule 
5635(c)(4), the board of directors or a committee of the board may also issue inducement grants outside of the 2021 Plan, material to an individual's 
entering into employment with the Company.

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the share options and the fair value of the 
Company’s ordinary shares for those share options that had exercise prices lower than the fair value of the ordinary shares as of the end of the 
period.

Options generally vest over periods of one to four years, and options that are forfeited or cancelled are available to be granted again. The contractual life of 
options is generally five or ten years from the grant date.

The assumptions used in the Black-Scholes option pricing model to determine the fair value of share options granted to employees during the period were 
as follows:

Risk-free interest rate
Expected term (in years)
Expected volatility
Expected dividend yield

In October 2022, the compensation committee of the Company’s board of directors granted Dr. Verdine, one of the Company’s founders and a member of 
the Company’s board of directors, a non-qualified share option for 163,467 ordinary shares as form of payment under Dr. Verdine’s consulting agreement 
for scientific advisory services (as described in Note 13) for the service period of October 1, 2022 through December 31, 2024, the vesting of which is 
subject to Dr. Verdine’s continued service under the consulting agreement. This was the only non-employee grant made during the year ended December 
31, 2022 and there were no options granted to non-employees during the year ended December 31, 2021. 

The assumptions used in the Black-Scholes option pricing model to determine the fair value of share options granted to non-employees during the period 
were as follows:

RSUs can be time-based or performance-based. Vesting of the performance-based RSUs is contingent on the occurrence of certain regulatory or 
commercial milestones. In March 2021, the Compensation Committee approved an amendment and restatement of the Company’s outstanding 2019 
performance-based RSUs to add an additional milestone to the existing milestones. In 2021, the Company also granted performance-based RSUs with the 
same terms to certain employees who did not receive the 2019 performance-based RSUs. The Company did not recognize expense in 2021 related to the 
performance-based RSUs as the related milestones were not considered probable of achievement. In April 2022, the Company determined that a 
performance-based RSU milestone was achieved and consequently 50% of the outstanding performance-based RSUs vested, which resulted in the issuance 
of 384,646 ordinary shares. During the year ended December 31, 2022, the Company recorded share-based compensation expense of approximately $3.8 
million, which represents all of the expense related to the achievement of this performance-based RSU milestone. The Company did not recognize any 
expense related to the other performance-based RSU milestones, as the remaining milestones were not considered probable of achievement as of December 
31, 2022.

RSUs that are forfeited are available to be granted again. During the year ended December 31, 2022, 143,700 time-based RSUs were granted to employees. 
Of the RSUs outstanding at December 31, 2022, 607,764 are time-based RSUs and 326,578 are performance-based RSUs. Time-based RSUs generally vest 
over periods of one to four years. 

As of December 31, 2022, the unrecognized compensation cost related to outstanding options was $9.7 million. The unrecognized compensation cost 
related to outstanding options is expected to be recognized over a weighted-average period of approximately 2.3 years. For the years ended December 31, 
2022 and 2021, the weighted-average grant date fair value per granted option was $2.06 and $3.48, respectively. The aggregate fair value of options that 
vested during the years ended December 31, 2022 and 2021 was $6.9 million and $5.7 million, respectively. The unrecognized compensation costs related 
to outstanding time-based RSUs was $1.7 million as of December 31, 2022, and is expected to be recognized over a weighted-average period of 
approximately 1.3 years. The total fair value of RSUs vested during the years ended December 31, 2022 and 2021 was $1.3 million and $1.7 million, 
respectively.

Employee Share Purchase Plan

The Wave Life Sciences Ltd. Employee Share Purchase Plan (“ESPP”) allows full-time and certain part-time employees to purchase the Company’s 
ordinary shares at a discount to fair market value. Eligible employees may enroll in a six-month offering period beginning every January 15th and July 15th. 
Shares are purchased at a price equal to 85% of the lower of the fair market value of the Company’s ordinary shares on the first business day or the last 
business day of an offering period. During the years ended

ordinary shares available for issuance under the ESPP.

Share-Based Compensation Expense

Share-based compensation expense for the years ended December 31, 2022 and 2021 is classified as operating expenses in the consolidated statements of 
operations and comprehensive loss as follows:

8. LEASES

Lease Arrangements

The Company enters into lease arrangements for its facilities. A summary of the arrangements is as follows:

Operating Leases

Lexington

On September 26, 2016, and as amended on December 31, 2016, the Company entered into a 10 year and 9-month lease, which includes two successive 
five-year renewal options, for its facility in Lexington, Massachusetts, which the Company uses primarily for its current good manufacturing practices 
(“cGMP”) manufacturing, as well as for additional laboratory and office space. As there is not reasonable certainty that the renewal options will be 
exercised, the lease liabilities and the right-of-use assets pertaining to the Lexington Lease do not account for the two successive five-year renewal options. 
Throughout the term of the lease, the Company is responsible for paying certain costs and expenses, in addition to the rent, as specified in the lease, 
including a proportionate share of applicable taxes, operating expenses and utilities. As required under the terms of the lease agreement, the Company has 
placed restricted cash of approximately $2.7 million in a separate bank account as of December 31, 2022 and 2021. 

Cambridge

In April 2015, the Company entered into a lease agreement for an office and laboratory facility in Cambridge, Massachusetts (the “Cambridge Lease”), 
which commenced in October 2015 with a term of 7.5 years with a five-year renewal option to extend the lease. Throughout the term of the lease, the 
Company is responsible for paying certain costs and expenses, in addition to the rent, as specified in the lease, including a proportionate share of applicable 
taxes, operating expenses and utilities. As required under the terms of the lease agreement, the Company has placed restricted cash of $1.0 million in a 
separate bank account as of December 31, 2022 and 2021. 

In December 2020, the Company exercised its option under the Cambridge Lease to lease the additional office and laboratory space at the existing facility. 
The combined space constitutes the entire building. The lease for the additional space commenced on October 1, 2021, with a term of five years and is 
considered a separate lease from the Cambridge Lease. On the commencement date, the Company utilized the operating lease classification and recorded a 
right-of-use asset and corresponding operating lease liability of $4.5 million and began recognizing straight-line rent expense under ASC 842. Throughout 
the term of the lease, the Company is responsible for paying certain costs and expenses, in addition to the rent, as specified in the lease, including a 
proportionate share of applicable taxes, operating expenses and utilities. 

In June 2022, the Company exercised the five-year renewal option under the Cambridge Lease to extend the lease term through March 2028 (the 
“Cambridge Lease Extension”). Therefore, as required by ASC 842, the Company calculated an incremental borrowing rate of 10.53% and remeasured the 
right-of-use asset and the lease liabilities related to the Cambridge Lease Extension. As a result, an additional $12.0 million of operating right-of-use asset 
and corresponding operating lease liabilities were recorded relating to the Cambridge Lease Extension.

9. COMMITMENTS AND CONTINGENCIES

Unasserted Claims

In the ordinary course of business, the Company may be subject to legal proceedings, claims and litigation as the Company operates in an industry 
susceptible to patent and other legal claims. The Company accounts for estimated losses with respect to legal proceedings and claims when such losses are 
probable and estimable. Legal costs associated with these matters are expensed when incurred. The Company is not currently a party to any material legal 
proceedings. 

10. NET LOSS PER ORDINARY SHARE

Basic loss per share is computed by dividing net loss attributable to ordinary shareholders by the weighted-average number of ordinary shares outstanding: 

Numerator:

Net loss attributable to ordinary shareholders

Denominator:

Weighted-average ordinary shares outstanding

As of December 31, 2022, there were 7,093,656 vested and exercisable Pre-Funded Warrants outstanding to purchase ordinary shares for the exercise price 
of $0.0001 per share. The Pre-Funded Warrants are included in the weighted-average shares outstanding used in the calculation of basic net loss per share 
as the exercise price is negligible and the warrants are fully vested and exercisable.

The Company’s potentially dilutive shares, which include outstanding share options to purchase ordinary shares and restricted share units, are considered to 
be ordinary share equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

The following potential ordinary shares, presented based on amounts outstanding at each period end, were excluded from the calculation of diluted net loss 
per share attributable to ordinary shareholders for the periods indicated because including them would have had an anti-dilutive effect:

During the years ended December 31, 2022 and 2021, the Company recorded an income tax provision of $0.7 million and an income tax benefit of $0.2 
million, respectively. The income tax provision for the year ended December 31, 2022 was primarily due to the requirement under the Tax Cuts and Jobs 
Act of 2017 for taxpayers to capitalize and amortize research and development expenditures over five or fifteen years pursuant to Section 174 of the 
Internal Revenue Code of 1986, as amended (the “Code”), partially offset by the utilization of net operating losses subject to the Section 382 limitation 
discussed below. The income tax benefit for the year ended December 31, 2021 was primarily due to the release of a portion of the Company’s uncertain 
tax positions as a result of a lapse in the statute of limitations. 

The components of the benefit (provision) for income taxes were as follows:

be available to offset future income tax liabilities indefinitely, while $0.8 million of carryforwards that were in existence as of December 31, 2017 may 
offset future income tax liabilities up through 2037. As of December 31, 2022, the Company had state net operating loss carryforwards of $43.9 million 
that will begin to expire in 2038. As of December 31, 2022 and 2021, the Company had U.S. federal research and development tax credit carryforwards of 
approximately $0.2 million and $12.8 million, respectively, available to offset future U.S. federal income taxes and will begin to expire in 2042. As of 
December 31, 2022 and 2021, the Company had state research and development tax credit carryforwards of approximately $0.2 million and $9.1 million, 
respectively, available to offset future state income taxes and will begin to expire in 2037, and no longer had state investment tax credit carryforwards. As 
of December 31, 2022, the Company no longer had a U.S. orphan drug credit carryforward.

As of December 31, 2022 and 2021, the Company had net operating loss carryforwards in Japan of $2.3 million and $2.7 million, respectively, which may 
be available to offset future income tax liabilities and begin to expire in 2023.

As of December 31, 2022 and 2021, the Company had net operating loss carryforwards in Singapore of $111.2 million and $189.2 million, respectively, 
which may be available to offset future income tax liabilities and can be carried forward indefinitely.

As of December 31, 2022 and 2021, the Company had net operating loss carryforwards in the United Kingdom of $314.5 million and $254.3 million, 
respectively, which may be available to offset future income tax liabilities and can be carried forward indefinitely.

The Company has evaluated the positive and negative evidence bearing upon its ability to realize its deferred tax assets. As of December 31, 2022, 
management has considered the Company’s history of cumulative net losses incurred since inception and its lack of commercialization of any products or 
generation of any revenue from product sales since inception and has concluded that it is more likely than not that the Company will not realize the benefits 
of the deferred tax assets in all jurisdictions. Accordingly, a full valuation allowance has been established against those deferred tax assets as of December 
31, 2022. 

The valuation allowance decreased by approximately $11.9 million in 2022. The decrease in the valuation allowance for 2022 was primarily a result of the 
2022 Section 382 limitation on the Company's utilization of its federal and state tax credits and state net operating losses before their expiration. The 
Company may release this valuation allowance when management determines that it is more-likely-than-not that the deferred tax assets will be realized. 
Any release of valuation allowance will be recorded as a tax benefit either increasing net income or decreasing net loss.

The Company’s reserves related to taxes and its accounting for uncertain tax positions are based on a determination of whether and how much of a tax 
benefit taken by the Company in its tax filings or positions is more-likely-than-not to be realized following resolution of any potential contingencies 
present related to the tax benefit.

A summary of activity in the Company’s unrecognized tax benefits is as follows:

Unrecognized tax benefit at the beginning of the year
Tax positions related to prior years
Tax positions related to statute lapse
Tax positions related to the current year
Unrecognized tax benefit at the end of the year

As of December 31, 2022 and 2021, the total amount of gross unrecognized tax benefits, which excludes interest and penalties, was $13.9 million and 
$19.9 million, respectively. At December 31, 2022, $0.2 million of the net unrecognized tax benefits would affect the Company’s annual effective tax rate 
if recognized. 

The Company files income tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company 
is subject to examination by various tax authorities in the United States, Japan, Singapore and the United Kingdom. Tax years from 2019 to the present are 
still open to examination in the United States, from 2017 to the present in Japan, from 2018 to the present in Singapore and from 2021 to the present in the 
United Kingdom. To the extent that the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted 
upon examination by the tax authorities to the extent utilized in a future period.

In October 2022, the Inland Revenue Authority of Singapore (“IRAS”) completed its examination of the Company’s corporate income tax returns for the 
2016 and 2017 tax years. The Company received notice of adjustments from IRAS indicating that certain R&D expenses are temporarily disallowed until 
the Company recognizes income related to the R&D initiatives. As a result of the final assessments made by IRAS, the Company reclassified $14.9 million 
of its net operating loss carryforward deferred tax assets to capitalized research and development deferred tax assets that remained subject to a full 
valuation allowance.

As of December 31, 2022 and 2021, $44.1 million and $21.1 million, respectively, of cash and cash equivalents were held by the subsidiaries outside of 
Singapore. The Company does not provide for Singapore income tax or foreign withholding taxes on foreign unrepatriated earnings, as the Company 
intends to permanently reinvest undistributed earnings in its foreign subsidiaries. If the Company decides to change this assertion in the future to repatriate 
any additional foreign earnings, the Company may be required to accrue and pay taxes. Because of the complexity of Singapore and foreign tax rules 
applicable to the distribution of earnings from foreign subsidiaries to Singapore, the determination of the unrecognized deferred tax liability on these 
earnings is not practicable.

Utilization of the net operating loss carryforwards and research and development tax credit carryforwards in the United States may be subject to a 
substantial annual limitation under Section 382 of the Code, due to ownership changes that have occurred previously or 

F-23

 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
that could occur in the future. These ownership changes may limit the amount of carryforwards that can be utilized annually to offset future taxable income. 
In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in 
the shares of a corporation by more than 50% over a three-year period. In 2018, 2020 and 2022, the Company completed studies to assess whether an 
ownership change had occurred or whether there have been multiple ownership changes since its formation. The results of the 2018 study indicated that the 
Company experienced an ownership change as defined by Section 382 of the Code. Based on the results of the 2018 study, management had determined 
that the limitations will not have a material impact on the Company’s ability to utilize its net operating losses and research and development credit 
carryforwards to offset future tax liabilities. The results of the 2020 study indicated that the Company did not experience an ownership change since the 
2018 study. The results of the 2022 study indicated that the Company experienced an ownership change and will be limited in its ability to utilize net 
operating losses and its research and development credit carryforwards in the 2022 tax year and going forward. Based on the 2022 study, $46.8 million of 
federal and state tax credits and $218.2 million of state net operating losses will expire unutilized. Should one or more ownership changes occur in the 
future, the Company’s ability to utilize its net operating losses and research and development credit carryforwards may be further limited. 

12. EMPLOYEE BENEFIT PLANS 

The Company has a 401(k) retirement and savings plan (the “401(k) Plan”) covering employees of Wave USA. The 401(k) Plan allows employees to make 
contributions up to the maximum allowable amount set by the Internal Revenue Service. Under the 401(k) Plan, the Company may make discretionary 
contributions as approved by the board of directors. The Company made contributions of $1.1 million and $1.0 million in the years ended December 31, 
2022 and 2021, respectively. 

13. RELATED PARTIES

The Company had the following related party transactions for the periods presented in the accompanying consolidated financial statements:

•

In 2012, the Company entered into a consulting agreement for scientific advisory services with Dr. Gregory L. Verdine, one of the 
Company’s founders and a member of the Company’s board of directors. The consulting agreement does not have a specific term and may be 
terminated by either party upon 14 days’ prior written notice. Pursuant to the consulting agreement, the Company pays Dr. Verdine 
approximately $13 thousand per month, plus reimbursement for certain expenses. In October 2022, the compensation committee of the 
Company’s board of directors granted Dr. Verdine a non-qualified share option for 163,467 ordinary shares as form of payment under this 
consulting agreement for the service period of October 1, 2022 through December 31, 2024, the vesting of which is subject to Dr. Verdine’s 
continued service under the consulting agreement.

14. SUBSEQUENT EVENTS

GSK Collaboration Agreement and GSK Equity Investment

On December 13, 2022, Wave USA and Wave UK entered into a Collaboration and License Agreement (the “GSK Collaboration Agreement”) with 
GlaxoSmithKline Intellectual Property (No. 3) (“GSK”). Pursuant to the GSK Collaboration Agreement, Wave and GSK have agreed to collaborate on the 
research, development, and commercialization of oligonucleotide therapeutics, including an exclusive global license to WVE-006. The discovery 
collaboration has an initial four-year research term and combines Wave’s proprietary discovery and drug development platform, PRISM, with GSK’s 
unique insights from human genetics and its global development and commercial capabilities. The GSK Collaboration Agreement became effective as of 
January 27, 2023, following the completion of customary closing conditions. 

In connection with the parties’ entry into the GSK Collaboration Agreement, Wave entered into a share purchase agreement on December 13, 2022 with 
Glaxo Group Limited (“GGL”), an affiliate of GSK, pursuant to which Wave agreed to sell to GGL 10,683,761 of its ordinary shares at a purchase price of 
$4.68 per share (the “GSK Equity Investment”). The GSK Equity Investment closed on January 26, 2023, following the completion of customary closing 
conditions. 

Subsequent to December 31, 2022 and in respect to the above referenced transactions, Wave received $170.0 million in cash, of which $120.0 million was 
an upfront payment under the GSK Collaboration Agreement and $50.0 million was the GSK Equity Investment.

DESCRIPTION OF SECURITIES REGISTERED PURSUANT
TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.2

Wave Life Sciences Ltd. (the “Company,” “we,” “us” or “our”) has one class of securities registered under Section 12 of the Securities Exchange Act of 
1934, as amended (the “Exchange Act”): our ordinary shares, no par value. 

DESCRIPTION OF SHARE CAPITAL

General 

The following description of our share capital and provisions of our constitution (formerly known as our memorandum and articles of association) 
are summaries and are qualified by reference to the Companies Act 1967 of Singapore ("Singapore Companies Act") and our constitution. A copy of our 
constitution has been filed with the Securities and Exchange Commission as an exhibit to our Annual Report on Form 10-K of which this Exhibit is a part. 

Ordinary Shares 

As of December 31, 2022, our issued and paid-up ordinary share capital consists of 86,924,643 ordinary shares. We currently have only one class of 
issued ordinary shares, which have identical rights in all respects and rank equally with one another. Our ordinary shares have no par value and there is no 
authorized share capital under Singapore law. There is a provision in our constitution which provides that we may issue shares with such preferred, deferred 
or other special rights or such restrictions, whether in regard to dividend, voting, return of capital or otherwise as our board of directors may determine. 

All of our shares presently issued are fully paid-up, and existing shareholders are not subject to any calls on these shares. Although Singapore law 
does not recognize the concept of “non-assessability” with respect to newly-issued shares, we note that any purchaser of our shares who has fully paid up 
all amounts due with respect to such shares will not be subject under Singapore law to any personal liability to contribute to the assets or liabilities of our 
company in such purchaser’s capacity solely as a holder of such shares. We believe that this interpretation is substantively consistent with the concept of 
“non-assessability” under most, if not all, U.S. state corporations laws. All of our shares are in registered form. We cannot, except in the circumstances 
permitted by the Singapore Companies Act, grant any financial assistance for the acquisition or proposed acquisition of our own shares. Except as 
described below under “—Takeovers,” there are no limitations imposed by the Singapore Companies Act or by our constitution on the right of shareholders 
not resident in Singapore to hold or vote ordinary shares. 

Transfer Agent and Registrar 

The transfer agent and registrar for our ordinary shares is Computershare Trust Company, N.A. 

Nasdaq Global Market 

Our ordinary shares are listed for quotation on The Nasdaq Global Market under the symbol “WVE.” 

New Shares 

Under the Singapore Companies Act, new shares may be issued only with the prior approval of our shareholders in a general meeting. General 

approval may be sought from our shareholders in a general meeting for the issue of shares. Approval, if granted, will lapse at the earlier of: 

• 

• 

the conclusion of the next annual general meeting; or 

the expiration of the period within which the next annual general meeting is required by law to be held (i.e., within six months after the end 
of each financial year), 

but any approval may be revoked or varied by the company in a general meeting. 

Our shareholders have provided such general authority to issue new ordinary shares until the conclusion of our 2023 annual general meeting. Such 

approval will lapse in accordance with the preceding paragraph if our shareholders do not grant a new approval at our 2023 annual general meeting. Subject 
to this and the provisions of the Singapore Companies Act and our constitution, our board 

1

 
 
 
 
of directors may allot and issue or grant options over or otherwise dispose of new ordinary shares to such persons on such terms and conditions and with 
the rights and restrictions as they may think fit to impose. 

Preferred Shares 

Series A Preferred Shares 

As of December 31, 2022, we have 3,901,348 Series A preferred shares outstanding. These shares are currently held by one of our largest 
shareholders, Shin Nippon Biomedical Laboratories, Ltd. The terms of the Series A preferred shares as set out in our constitution include (1) no voting 
rights at any general meeting other than in limited circumstances, (2) a liquidation preference equal to $0.002 per Series A preferred share, (3) no 
entitlement to dividends and (4) the right to convert the Series A preferred shares at any time on a one-for-one basis into ordinary shares at the discretion of 
the holder in accordance with the constitution. 

The holders of the Series A preferred shares are not entitled to vote at any general meeting. The only instances in which the holders of the Series A 
preferred shares are able to vote at a general meeting would be if (but only if) the matters to be discussed at the meeting relate to or there is intent to pass 
resolutions on (i) abrogating or changing the rights attached to the Series A preferred shares; and (ii) for the winding up of the Company. Such resolutions 
would require the unanimous approval of the holders of the Series A preferred shares. 

Other Preferred Shares 

Under the Singapore Companies Act, different classes of shares in a public company may be issued only if (a) the issue of the class or classes of 

shares is provided for in the constitution of the public company and (b) the constitution of the public company sets out in respect of each class of shares the 
rights attached to that class of shares. Our constitution provides that we may issue shares of a different class with preferred, deferred or other special rights, 
or such restrictions, whether in regard to dividend, voting, return of capital or otherwise as our board of directors may determine. Under Singapore law, our 
preferred shareholders will have the right to attend any general meeting and in a poll at such general meeting, to have at least one vote for every preferred 
share held: 

• 

• 

• 

upon any resolution concerning the voluntary winding-up of our company under Section 160 of the Insolvency, Restructuring and 
Dissolution Act 2018; 

upon any resolution which varies the rights attached to such preferred shares; or 

in the case of preferred shares issued after August 15, 1984, but before the commencement of Section 96 of the Companies (Amendment) 
Act 2014, when the dividends to be paid on our preferred shares or any part thereof are more than twelve months in arrears and unpaid, for 
the period they remain in arrears and unpaid. 

We may, subject to the Singapore Companies Act and the prior approval in a general meeting of our shareholders, issue preferred shares which are, 

or at our option or are to be, subject to redemption provided that such preferred shares may not be redeemed out of capital unless: 

• 

all the directors have made a solvency statement in relation to such redemption; and 

•  we have lodged a copy of the statement with the Accounting and Corporate Regulatory Authority of Singapore. 

Further, such shares must be fully paid-up before they are redeemed. 

As of December 31, 2022, we have no preferred shares outstanding other than the Series A preferred shares described above. At present, we have no 

plans to issue additional preferred shares. 

Pre-Funded Warrants

As of December 31, 2022, we have pre-funded warrants outstanding to purchase up to 7,093,656 ordinary shares. The pre-funded warrants are 

exercisable at any time after their original issuance and on or prior to 5:00 p.m. (New York City time) on the five year anniversary of the original issuance 
date, which was June 16, 2022. The pre-funded warrants are exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed 
exercise notice and by payment in full of the exercise price in immediately available funds for the number of ordinary shares purchased upon such exercise. 
As an alternative to payment in immediately available funds, the holder may elect to exercise the pre-funded warrant through a cashless exercise, in which 
the holder would receive upon such exercise the net number of ordinary shares determined according to the formula set forth in the pre-funded warrant. No 
fractional ordinary shares will be issued in connection with the exercise of a pre-funded warrant.

Exercise Limitations

2

 
 
 
Under the pre-funded warrants, unless and until the Shareholder Approval (as defined below) is obtained, we may not effect the exercise of any 
pre-funded warrant, and a holder will not be entitled to exercise any portion of any pre-funded warrant, which, upon giving effect to such exercise, would 
cause (i) the aggregate number of our ordinary shares beneficially owned by the holder (together with its affiliates) to exceed 19.99% of the number of our 
ordinary shares outstanding immediately after giving effect to the exercise, or (ii) the combined voting power of our securities beneficially owned by the 
holder (together with its affiliates) to exceed 19.99% of the combined voting power of all of our securities then outstanding immediately after giving effect 
to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants.

Upon the written request of the holder delivered to us and subsequent to December 31, 2022, we shall use commercially reasonable efforts to 

obtain shareholder approval (the “Shareholder Approval”), at our next regularly scheduled annual general meeting of shareholders, for the issuance of the 
pre-funded warrant shares upon the exercise of all or any portion of the pre-funded warrants such that such issuance of pre-funded warrant shares will 
comply with the Listing Rules of the Nasdaq Stock Market, including, without limitation, Listing Rule 5635, and with applicable Singapore law. In the 
event that the holder requests the Shareholder Approval, we use commercially reasonable efforts to obtain Shareholder Approval at our next regularly 
scheduled annual general meeting, and Shareholder Approval is not obtained at such meeting for any reason, then the holder may again request Shareholder 
Approval each year pursuant to and subject to the terms of the pre-funded warrants, at each of our subsequent regularly scheduled annual general meetings 
that occur prior to the termination date of the pre-funded warrants. We shall not be obligated to seek the Shareholder Approval at any shareholder meeting 
other than our regularly scheduled annual shareholder meeting and such written request of the holder must be received by us at least 90 days in advance of 
such annual meeting.

Exercise Price

The exercise price per whole share of our ordinary shares purchasable upon the exercise of the pre-funded warrants is $0.0001 per ordinary 

share. The exercise price of the pre-funded warrants and the number of our ordinary shares issuable upon exercise of the pre-funded warrants is subject to 
appropriate adjustment in the event of certain share dividends and distributions, share splits, share combinations, reclassifications or similar events 
affecting our ordinary shares.

Transferability

Subject to applicable laws, the pre-funded warrants may be offered for sale, sold, transferred or assigned without our consent.

Exchange Listing

We do not plan on applying to list the pre-funded warrants on The Nasdaq Global Market, any other national securities exchange or any other 

nationally recognized trading system.

Fundamental Transactions

In the event of a fundamental transaction, as described in the pre-funded warrants and generally including any reorganization, recapitalization or 
reclassification of our ordinary shares, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger 
with or into another person, the acquisition of more than 50% of our outstanding ordinary shares, or any person or group becoming the beneficial owner of 
50% of the voting power represented by our outstanding ordinary shares, upon consummation of such a fundamental transaction, the holders of the pre-
funded warrants will be entitled to receive upon exercise of the pre-funded warrants the kind and amount of securities, cash or other property that the 
holders would have received had they exercised the pre-funded warrants immediately prior to such fundamental transaction without regard to any 
limitations on exercise contained in the pre-funded warrants.

No Rights as a Shareholder

Except by virtue of such holder’s ownership of our ordinary shares, the holder of a pre-funded warrant does not have the rights or privileges of a 
holder of our ordinary shares, including any voting rights, until the holder exercises the pre-funded warrant. In the event of certain distributions, including 
cash dividends, if any, to all holders of our ordinary shares for no consideration, the holder of a pre-funded warrant shall be entitled to participate in such 
distributions to the same extent as if a holder of our ordinary shares, subject to not exceeding the ownership limitations described above under “—Exercise 
Limitations,” in which case such distribution shall be held in abeyance for the benefit of such holder until the earlier of such time as the ownership 
limitations would not be exceeded or the warrant is exercised.

Registration Rights under our Share Purchase Agreement with Pfizer 

Under the terms of our Share Purchase Agreement dated as of May 5, 2016 with an affiliate of Pfizer Inc., or the Pfizer Affiliate, under which the 

Pfizer Affiliate purchased 1,875,000 ordinary shares from, or the Pfizer Shares, subject to certain conditions and 

3

 
 
 
  
 
 
 
 
 
 
 
limitations, we agreed to provide certain demand registration rights to the Pfizer Affiliate in order to register all or a portion of the Pfizer Shares purchased 
by the Pfizer Affiliate. We also provided the Pfizer Affiliate with certain “piggyback” registration rights for a certain period of time, subject to certain 
conditions and limitations, such that when we propose to register our ordinary shares for our account, the Pfizer Affiliate will have the right to include 
some or all of the Pfizer Shares in such registration. The Share Purchase Agreement also contains other customary terms and conditions of the parties with 
respect to the registration of the Pfizer Shares. 

Registration Rights under our Share Purchase Agreement with Takeda 

On February 19, 2018, we entered into a Share Purchase Agreement (the “Takeda Share Purchase Agreement”) with Takeda Pharmaceutical 
Company Limited (“Takeda”), pursuant to which Takeda purchased 1,096,892 of our ordinary shares (the “Takeda Shares”). In connection with the Takeda 
Share Purchase Agreement, Takeda and we agreed upon certain rights and restrictions as set forth in the Investor Agreement, dated as of April 2, 2018 (the 
“Takeda Investor Agreement”). Subject to certain conditions and limitations, we agreed to provide certain demand registration rights to Takeda in order to 
register all or a portion of the Takeda Shares purchased by Takeda. We also provided Takeda with certain “piggyback” registration rights for a certain 
period of time, subject to certain conditions and limitations, such that when we propose to register our ordinary shares for our account, Takeda will have the 
right to include some or all of the Takeda Shares in such registration. The Takeda Investor Agreement also contains other customary terms and conditions 
of the parties with respect to the registration of Takeda Shares. 

Registration Rights under our Share Purchase Agreement with GSK 

On December 13, 2022, we entered into a Share Purchase Agreement (the “GSK Share Purchase Agreement”) with Glaxo Group Limited (“GGL”), 

an affiliate of GlaxoSmithKline Intellectual Property (No. 3) (“GSK”), pursuant to which we sold 10,683,761 of our ordinary shares to GGL (the “GGL 
Shares”). In connection with the GSK Share Purchase Agreement, GGL and we agreed upon certain rights and restrictions as set forth in the Investor 
Agreement, dated as of January 26, 2023 (the “GSK Investor Agreement”). The GGL Shares are subject to a lock-up restriction, such that GGL will not, 
and will also cause its affiliates not to, without our prior approval, sell, transfer or otherwise dispose of the GGL Shares during the 30-month period after 
the effective date of the GGL Investor Agreement. For a certain period following the expiration of the lock-up period, subject to certain conditions and 
limitations, we agreed to provide certain demand registration rights to GGL in order to register all or a portion of the GGL Shares purchased by GGL. We 
also provided GGL with certain “piggyback” registration rights for a certain period following the expiration of the lock-up period, subject to certain 
conditions and limitations, such that when we propose to register our ordinary shares for our account, GGL will have the right to include some or all of the 
GGL Shares in such registration. The GSK Investor Agreement also contains other customary terms and conditions of the parties with respect to the 
registration of GGL Shares.

Transfer of Ordinary Shares 

Subject to applicable securities laws in relevant jurisdictions and our constitution, our ordinary shares are freely transferable. Our constitution 

provides that shares may be transferred by a duly signed instrument of transfer in any usual or common form or in a form approved by the directors and 
The Nasdaq Stock Market. The directors may decline to register any transfer unless, among other things, evidence of payment of any stamp duty payable 
with respect to the transfer is provided together with other evidence of ownership and title as the directors may reasonably require to show the right of the 
transferor to make the transfer. We will replace lost or destroyed certificates for shares upon notice to us and upon, among other things, the applicant 
furnishing evidence and indemnity as the directors may require and the payment of all applicable fees. 

Election and Re-election of Directors 

We may, by ordinary resolution, remove any director before the expiration of his or her period of office, notwithstanding anything in our constitution 

or in any agreement between us and such director. We may also, by an ordinary resolution, appoint another person in place of a director removed from 
office pursuant to the foregoing. 

Under our constitution, subject to the Singapore Companies Act, any director shall retire at the next annual general meeting and shall then be 

eligible for re-election at that meeting. 

Our board of directors shall have the power, at any time and from time to time, to appoint any person to be a director either to fill a casual vacancy 

or as an additional director so long as the total number of directors shall not at any time exceed the maximum number (if any) fixed by or in accordance 
with our constitution. 

Shareholders’ Meetings 

We are required to hold an annual general meeting each calendar year and within six months after the end of each financial year. The directors may 
convene an extraordinary general meeting whenever they think fit and they must do so upon the written request of shareholders holding not less than 10% 
of the total number of paid-up shares as of the date of deposit of the requisition carrying the 

4

right to vote at a general meeting. In addition, two or more shareholders holding not less than 10% of our total number of issued shares (excluding our 
treasury shares) may call a meeting of our shareholders. 

The Singapore Companies Act provides that a shareholder is entitled to attend any general meeting and speak on any resolution put before the 
general meeting. Unless otherwise required by law or by our constitution, resolutions put forth at general meetings may be decided by ordinary resolution, 
requiring the affirmative vote of a majority of the shareholders present in person or represented by proxy at the meeting and entitled to vote on the 
resolution. An ordinary resolution suffices, for example, for appointments of directors. A special resolution, requiring an affirmative vote of not less than 
three-fourths of the shareholders present in person or represented by proxy at the meeting and entitled to vote on the resolution, is necessary for certain 
matters under Singapore law, such as an alteration of our constitution. A shareholder entitled to attend and vote at a meeting of the company, or at a 
meeting of any class of shareholders of the company, is entitled to appoint another person or persons, whether a shareholder of the company or not, as the 
shareholder's proxy to attend and vote instead of the shareholder at the meeting. Under the Singapore Companies Act, a proxy appointed to attend and vote 
instead of the shareholder also has the same right as the shareholder to speak at the meeting, but unless the constitution of the company otherwise provides, 
(i) a proxy is not entitled to vote except on a poll, (ii) a shareholder is not entitled to appoint more than two proxies to attend and vote at the same meeting 
and (iii) where a shareholder appoints two proxies the appointments are invalid unless the shareholder specifies the proportions of the shareholder's 
holdings to be represented by each proxy. 

Notwithstanding the foregoing, a registered shareholder entitled to attend and vote at a meeting of the company held pursuant to an order of court 
under Section 210(1) of the Singapore Companies Act, or at any adjourned meeting under Section 210(3) of the Singapore Companies Act, is, unless the 
court orders otherwise, entitled to appoint only one proxy to attend and vote at the same meeting, and except where the aforementioned applies, a registered 
shareholder having a share capital who is a relevant intermediary (as defined under the Singapore Companies Act) may appoint more than two proxies in 
relation to a meeting to exercise all or any of the shareholder's rights to attend and to speak and vote at the meeting, but each proxy must be appointed to 
exercise the rights attached to a different share or shares held by the shareholder (which number and class of shares shall be specified), and at such meeting, 
the proxy has the right to vote on a show of hands. 

Only registered shareholders of our company, and their proxies, will be entitled to attend, speak and vote at any meeting of shareholders. Under the 
Singapore Companies Act, public companies may issue non-voting shares and shares that confer special, limited or conditional voting rights, such that the 
holder of a share may vote on a resolution before a general meeting of the company if, in accordance with the provisions of Section 64A of the Singapore 
Companies Act, the share confers on the holder a right to vote on that resolution. 

Voting Rights 

As provided under our constitution and the Singapore Companies Act, voting at any meeting of shareholders is by show of hands unless a poll has 

been demanded prior to the declaration of the result of the show of hands by, among others, (i) the chairman or (ii) at least one shareholder present in 
person or by proxy or by attorney or, in the case of a corporation, by a representative entitled to vote thereat, in each case representing in the aggregate not 
less than 5% of the total voting rights of all shareholders having the right to vote at the general meeting, provided that no poll shall be demanded in respect 
of an election of a chairman or relating to any adjournment of such meeting. On a poll every shareholder who is present in person or by proxy or by 
attorney, or in the case of a corporation, by a representative, has one vote for every share held by such shareholder. Proxies need not be shareholders. 

Only those shareholders who are registered in our register of members as holders of ordinary shares will be entitled to vote at any meeting of 

shareholders. Therefore, DTC, or its nominee, will grant an omnibus proxy to DTC participants holding our shares in book-entry form through a broker, 
bank, nominee, or other institution that is a direct or indirect participant in the DTC. Such shareholders will have the right to instruct their broker, bank, 
nominee or other institution holding these shares on how to vote such shares by completing the voting instruction form provided by the applicable broker, 
bank, nominee, or other institution. Whether voting is by a show of hands or by a poll, DTC’s vote will be voted by the chairman of the meeting according 
to the results of the DTC’s participants’ votes (which results will reflect the instructions received from shareholders that own our shares electronically in 
book-entry form). 

Minority Rights 

The rights of minority shareholders of Singapore companies are protected, among other things, under Section 216 of the Singapore Companies Act, 
which gives the Singapore courts a general power to make any order, upon application by any shareholder of a company, as they think fit to remedy any of 
the following situations: 

• 

the affairs of a company are being conducted or the powers of the board of directors are being exercised in a manner oppressive to, or in 
disregard of the interests of, one or more of the shareholders, including the applicant; or 

5

• 

a company takes an action, or threatens to take an action, or the shareholders pass a resolution, or propose to pass a resolution, which 
unfairly discriminates against, or is otherwise prejudicial to, one or more of the shareholders, including the applicant. 

Singapore courts have wide discretion as to the remedy they may grant, and the remedies listed in the Singapore Companies Act itself are not 

exclusive. In general, Singapore courts may, with a view to bringing to an end or remedying the matters complained of: 

direct or prohibit any act or cancel or modify any transaction or resolution; 

regulate the conduct of the affairs of the company in the future; 

authorize civil proceedings to be brought in the name of, or on behalf of, the company by a person or persons and on such terms as the court 
may direct; 

provide for the purchase of a minority shareholder’s shares by the other shareholders or by the company itself; 

in the case of a purchase of shares by the company provide for a reduction accordingly of the company’s capital; or 

provide that the company be wound up.

Dividends 

Subject to any preferential rights of holders of any outstanding preferred shares, holders of our ordinary shares will be entitled to receive dividends 

and other distributions in cash, shares or property as may be declared by our company from time to time. We may, by ordinary resolution, declare dividends 
at a general meeting of shareholders, but we are restricted from paying dividends in excess of the amount recommended by our board of directors. Pursuant 
to Singapore law and our constitution, no dividend may be paid except out of our profits. To date, we have not declared any cash dividends on our ordinary 
shares and have no current plans to pay cash dividends in the foreseeable future. 

Bonus and Rights Issues 

In a general meeting, our shareholders may, upon the recommendation of the directors, capitalize any reserves or profits and distribute them as 

bonus shares, credited as paid-up, to the shareholders in proportion to their shareholdings. 

Subject to the provisions of the Singapore Companies Act and our constitution, our directors may also issue rights to take up additional ordinary 

shares to our shareholders in proportion to their respective ownership. Such rights are subject to any condition attached to such issue and the regulations of 
any stock exchange on which our shares are listed, as well as U.S. federal and blue sky securities laws applicable to such issue. 

Takeovers 

The Singapore Code on Take-overs and Mergers applies to, among other things, the acquisition of voting shares of Singapore-incorporated listed 

public companies or unlisted public companies with more than 50 shareholders and net tangible assets of S$5 million or more. Any person acquiring, 
whether by a series of transactions over a period of time or not, either on his or her own or together with parties acting in concert with such person, 30% or 
more of our voting shares, or, if such person holds, either on his or her own or together with parties acting in concert with such person, between 30% and 
50% (both amounts inclusive) of our voting shares, and if such person (or parties acting in concert with such person) acquires additional voting shares 
representing more than 1% of our voting shares in any six-month period, must, except with the consent of the Securities Industry Council in Singapore, 
extend a mandatory takeover offer for the remaining voting shares in accordance with the provisions of the Singapore Code on Take-overs and Mergers. 
Responsibility for ensuring compliance with the Singapore Code on Take-overs and Mergers rests with parties (including company directors) to a take-over 
or merger and their advisors. 

“Parties acting in concert” comprise individuals or companies who, pursuant to an agreement or understanding (whether formal or informal), 

cooperate, through the acquisition by any of them of shares in a company, to obtain or consolidate effective control of that company. Certain persons are 
presumed (unless the presumption is rebutted) to be acting in concert with each other. They are as follows: 

• 

• 

a company, its parent company, subsidiaries and fellow subsidiaries, the associated companies of any of the company and its related 
companies, subsidiaries and fellow subsidiaries, companies whose associated companies include any of these companies and any person 
who has provided financial assistance (other than a bank in the ordinary course of business) to any of the foregoing for the purchase of 
voting rights; 

a company with any of its directors (together with their close relatives, related trusts and companies controlled by any of the directors, their 
close relatives and related trusts); 

6

 
• 

• 

• 

• 

• 

• 

a company with any of its pension funds and employee share schemes; 

a person with any investment company, unit trust or other fund whose investment such person manages on a discretionary basis, but only in 
respect of the investment account which such person manages; 

a financial or other professional advisor, including a stockbroker, with its client in respect of the shareholdings of the advisor and persons 
controlling, controlled by or under the same control as the advisor; 

directors of a company (together with their close relatives, related trusts and companies controlled by any of such directors, their close 
relatives and related trusts) which is subject to an offer or where the directors have reason to believe a bona fide offer for their company 
may be imminent; 

partners; and 

an individual and (i) such person’s close relatives, (ii) such person’s related trusts, (iii) any person who is accustomed to act in accordance 
with such person’s instructions, (iv) companies controlled by the individual, such person’s close relatives, related trusts or any person who 
is accustomed to act in accordance with such person’s instructions and (v) any person who has provided financial assistance (other than a 
bank in the ordinary course of business) to any of the foregoing for the purchase of voting rights. 

Subject to certain exceptions, a mandatory offer must be in cash or be accompanied by a cash alternative at not less than the highest price paid by 

the offeror or parties acting in concert with the offeror during the offer period and within the six months prior to its commencement. 

Under the Singapore Code on Take-overs and Mergers, where effective control of a company is acquired or consolidated by a person, or persons 

acting in concert, a general offer to all other shareholders is normally required. An offeror must treat all shareholders of the same class in an offeree 
company equally. A fundamental requirement is that shareholders in the company subject to the takeover offer must be given sufficient information, advice 
and time to consider and decide on the offer. These legal requirements may impede or delay a takeover of our company by a third party. 

We may submit an application to the Securities Industry Council of Singapore for a waiver from the Singapore Code on Take-overs and Mergers so 

that the Singapore Code on Take-overs and Mergers will not apply to our company for so long as we are not listed on a securities exchange in Singapore. 
We will make an appropriate announcement if we submit the application and when the result of the application is known. 

Liquidation or Other Return of Capital 

On a winding-up or other return of capital, subject to any special rights attaching to the Series A preferred shares or to any other class of shares, 

holders of ordinary shares will be entitled to participate in any surplus assets in proportion to their shareholdings.

COMPARISON OF SHAREHOLDER RIGHTS

We are incorporated under the laws of Singapore. The following discussion summarizes material differences between the rights of holders of our 
ordinary shares and the rights of holders of the common stock of a typical corporation incorporated under the laws of the state of Delaware which result 
from differences in governing documents and the laws of Singapore and Delaware.

This discussion does not purport to be a complete statement of the rights of holders of our ordinary shares under applicable law in Singapore and our 

constitution or the rights of holders of the common stock of a typical corporation under applicable Delaware law and a typical certificate of incorporation 
and bylaws.

Delaware

Board of Directors

    Singapore

A typical certificate of incorporation and bylaws provides that the number 
of directors on the board of directors will be fixed from time to time by a 
vote of the majority of the authorized directors. Under Delaware law, a 
board of directors can be divided into classes and cumulative voting in the 
election of directors is only permitted if expressly authorized in a 
corporation’s certificate of incorporation.

The constitution of companies will typically state the minimum and 
maximum number of directors as well as provide that the number of 
directors may be increased or reduced by shareholders via ordinary 
resolution passed at a general meeting, provided that the number of 
directors following such increase or reduction is within the maximum (if 
any) and minimum number of directors provided in our constitution and the 
Singapore Companies Act, respectively.

Limitation on Personal Liability of Directors and Officers

A typical certificate of incorporation provides for the elimination of 
personal monetary liability of directors or officers for breach of fiduciary 
duties as directors or officers to the fullest extent permissible under the 
laws of Delaware, except for liability (i) for any breach of a director’s or 
officer’s duty of loyalty to the corporation or its stockholders, (ii) for acts or 
omissions not in good faith or which involve intentional misconduct or a 
knowing violation of law, (iii) of directors under Section 174 of the 
Delaware General Corporation Law (relating to the liability of directors for 
unlawful payment of a dividend or an unlawful stock purchase or 
redemption),  (iv) for any transaction from which the director or officer 
derived an improper personal benefit, or (v) of officers in any action by or 
in the right of the corporation. A typical certificate of incorporation also 
provides that if the Delaware General Corporation Law is amended so as to 
allow further elimination of, or limitations on, director or officer liability, 
then the liability of directors or officers will be eliminated or limited to the 
fullest extent permitted by the Delaware General Corporation Law as so 
amended.

Pursuant to the Singapore Companies Act, any provision (whether in the 
constitution, a contract with the company or otherwise) exempting or 
indemnifying a director against any liability which by law would otherwise 
attach to him or her in respect of any negligence, default, breach of duty or 
breach of trust of which such director may be guilty in relation to the 
company is void. However, a company is not prohibited from (a) 
purchasing and maintaining for any such director insurance against any 
such liability, or (b) indemnifying such director against any liability 
incurred by him or her to a person other than the company except when the 
indemnity is against any liability (i) of the director to pay a fine in criminal 
proceedings, (ii) of the director to pay a penalty in respect of non-
compliance with any regulatory requirements, (iii) incurred by the director 
in defending criminal proceedings in which he or she is convicted, (iv) 
incurred by the director in defending civil proceedings brought by the 
company or a related company in which judgment is given against him or 
her, or (v) incurred by the director in connection with an application for 
relief under Section 76A(13) or Section 391 of the Singapore Companies 
Act in which the court refuses to grant him or her relief. Nevertheless, a 
director can be released by the shareholders of a company for breaches of 
duty to a company except in the case of fraud, illegality, insolvency of the 
company and oppression or disregard of minority interests.

Subject to the Singapore Companies Act and every other Singapore statute 
for the time being in force and affecting the Company, we may indemnify 
our directors against costs, charges, fees, and other expenses that may be 
incurred by any of them in defending any proceedings (whether civil or 
criminal) relating to anything done or omitted or alleged to be done or 
omitted by such person acting in his or her capacity as a director of our 
company, in which judgment is given in his or her favor, or in which he or 
she is acquitted or in which the courts have granted relief pursuant to the 
provisions of the Singapore Companies Act,

    Singapore

Interested Shareholders

Section 203 of the Delaware General Corporation Law generally prohibits a 
Delaware corporation from engaging in specified corporate transactions 
(such as mergers, stock and asset sales, and loans) with an “interested 
stockholder” for three years following the time that the stockholder 
becomes an interested stockholder. Subject to specified exceptions, an 
“interested stockholder” is a person or group that owns 15% or more of the 
corporation’s outstanding voting stock (including any rights to acquire 
stock pursuant to an option, warrant, agreement, arrangement or 
understanding, or upon the exercise of conversion or exchange rights, and 
stock with respect to which the person has voting rights only), or is an 
affiliate or associate of the corporation and was the owner of 15% or more 
of the voting stock at any time within the previous three years.

A Delaware corporation may elect to “opt out” of, and not be governed by, 
Section 203 through a provision in either its original certificate of 
incorporation, or an amendment to its original certificate or bylaws that was 
approved by majority stockholder vote. With a limited exception, this 
amendment would not become effective until 12 months following its 
adoption.

Removal of Directors

A typical certificate of incorporation and bylaws provide that, subject to the 
rights of holders of any preferred stock, directors may be removed at any 
time by the affirmative vote of the holders of at least a majority, or in some 
instances a supermajority, of the voting power of all of the then outstanding 
shares entitled to vote generally in the election of directors, voting together 
as a single class. A certificate of incorporation could also provide that such 
a right is only exercisable when a director is being removed for cause 
(removal of a director only for cause is the default rule in the case of a 
classified board).

provided that such indemnity shall not extend to any liability which by law 
would otherwise attach to him or her in respect of any negligence, default, 
breach of duty or breach of trust of which he may be guilty in relation to 
our company, or which would otherwise result in such indemnity being 
voided under applicable Singapore laws.

There are no comparable provisions under the Singapore Companies Act 
with respect to public companies which are not listed on the Singapore 
Exchange Securities Trading Limited.

Under the Singapore Companies Act, directors of a public company may be 
removed before expiration of their term of office, despite anything in its 
constitution or in any agreement between the public company and such 
directors, by ordinary resolution (i.e., a resolution which is passed by a 
simple majority of those shareholders present and voting in person or by 
proxy). Notice of the intention to move such a resolution has to be given to 
the company not less than 28 days before the meeting at which it is moved. 
The company must then give notice of such resolution to its shareholders 
not less than 14 days before the meeting. Where any director removed in 
this manner was appointed to represent the interests of any particular class 
of shareholders or debenture holders, the resolution to remove the director 
does not take effect until the director’s successor has been appointed.

Filling Vacancies on the Board of Directors

A typical certificate of incorporation and bylaws provide that, subject to the 
rights of the holders of any preferred stock, any vacancy, whether arising 
through death, resignation, retirement, disqualification, removal, an 
increase in the number of directors or any other reason, may be filled by a 
majority vote of the remaining directors, even if such directors remaining in 
office constitute less than a quorum, or by the sole remaining director. Any 
newly elected director usually holds office for the remainder 

The constitution of a Singapore company typically provides that the 
directors have the power to appoint any person to be a director, either to fill 
a vacancy or as an addition to the existing directors, but so that the total 
number of directors shall not at any time exceed the maximum number (if 
any) fixed by or in accordance with the constitution. Any director so 
appointed shall hold office until the next following annual general meeting, 
where such director will then be eligible for re-election. Our

of the full term expiring at the annual meeting of stockholders at which the 
term of the class of directors to which the newly elected director has been 
elected expires.

    Singapore

constitution provides that the directors may appoint any person to be a 
director either to fill a casual vacancy or as an additional director but so 
that the total number of directors shall not at any time exceed the maximum 
number fixed by or in accordance with the constitution.

Amendment of Governing Documents

Under the Delaware General Corporation Law, amendments to a 
corporation’s certificate of incorporation require the approval of 
stockholders holding a majority of the outstanding shares entitled to vote on 
the amendment. If a class vote on the amendment is required by the 
Delaware General Corporation Law, a majority of the outstanding stock of 
the class is required, unless a greater proportion is specified in the 
certificate of incorporation or by other provisions of the Delaware General 
Corporation Law.

Under the Delaware General Corporation Law, the board of directors may 
amend bylaws if so authorized in the certificate of incorporation. The 
stockholders of a Delaware corporation also have the power to amend 
bylaws.

Our constitution may be altered by special resolution (i.e., a resolution 
passed by at least a three-fourths majority of the shareholders entitled to 
vote, present in person or by proxy at a meeting for which not less than 21 
days’ written notice is given). The board of directors has no right to amend 
the constitution.

Under the Singapore Companies Act, an entrenching provision may be 
included in the constitution with which a company is formed and may at 
any time be inserted into the constitution of a company only if all the 
shareholders of the company agree. An entrenching provision is a provision 
of the constitution of a company to the effect that other specified provisions 
of the constitution may not be altered in the manner provided by the 
Singapore Companies Act or may not be so altered except (i) by a 
resolution passed by a specified majority greater than 75% (the minimum 
majority required by the Singapore Companies Act for a special resolution) 
or (ii) where other specified conditions are met. The Singapore Companies 
Act provides that such entrenching provision may be removed or altered 
only if all the members of the company agree.

Meetings of Shareholders

Annual and Special Meetings

  Annual General Meetings

Typical bylaws provide that annual meetings of stockholders are to be held 
on a date and at a time fixed by the board of directors. Under the Delaware 
General Corporation Law, a special meeting of stockholders may be called 
by the board of directors or by any other person authorized to do so in the 
certificate of incorporation or the bylaws.

All companies are required to hold an annual general meeting after the end 
of each financial year within either 4 months (in the case of a public 
company that is listed on an exchange in Singapore approved by the 
Monetary Authority of Singapore) or 6 months (in the case of any other 
company).

  Extraordinary General Meetings

Any general meeting other than the annual general meeting is called an 
“extraordinary general meeting.” Despite anything in the constitution, 
directors of a company must convene an extraordinary general meeting if 
required to do so by requisition (i.e. written notice, requiring that a meeting 
be called, given to the directors) by shareholder(s) holding not less than 
10% of the total number of paid-up shares as at the date of the deposit of 
the requisition carrying the right of voting at general meetings of the 
company. In addition, the constitution usually also provides that general 
meetings may be convened in accordance with the Singapore Companies 
Act by the directors.

Quorum Requirements

  Quorum Requirements

Under the Delaware General Corporation Law, a corporation’s certificate of 
incorporation or bylaws can specify the number of shares which constitute 
the quorum required to conduct business 

Our constitution provides that any two shareholders present in person or by 
proxy or by attorney or, in the case of a corporation, by a representative and 
entitled to vote thereat; in each case

Delaware
at a meeting, provided that in no event shall a quorum consist of less than 
one-third of the shares entitled to vote at a meeting.

Indemnification of Officers, Directors and Employees

Under the Delaware General Corporation Law, subject to specified 
limitations in the case of derivative suits brought by a corporation’s 
stockholders in its name, a corporation may indemnify any person who is 
made a party to any third-party action, suit or proceeding on account of 
being a director, officer, employee or agent of the corporation (or was 
serving at the request of the corporation in such capacity for another 
corporation, partnership, joint venture, trust or other enterprise) against 
expenses, including attorney’s fees, judgments, fines and amounts paid in 
settlement actually and reasonably incurred by him or her in connection 
with the action, suit or proceeding through, among other things, a majority 
vote of a quorum consisting of directors who were not parties to the suit or 
proceeding, if the person:

    Singapore

representing in aggregate not less than a majority of the total voting rights 
of all shareholders having the right to vote at a general meeting, shall 
constitute a quorum. In the event a quorum is not present, the meeting if not 
convened on the requisition of shareholders may be adjourned for one 
week. When reconvened, the quorum for the meeting will be the same and 
if at such adjourned meeting a quorum is not present, the meeting will be 
dissolved.

Shareholders’ Rights at Meetings

The Singapore Companies Act provides that every member has, despite any 
provision in the constitution, a right to attend any general meeting of the 
company and to speak on any resolution before the meeting. The 
company’s constitution may provide that a member shall not be entitled to 
vote unless all calls or other sums personally payable by the member in 
respect of shares in the company have been paid.

Public companies may issue non-voting shares and shares that confer 
special, limited and conditional voting rights, such that the holder of a share 
may vote on a resolution before a general meeting if, in accordance with 
the provisions of Section 64A of the Singapore Companies Act, the share 
confers on the holder a right to vote on the resolution.

  Circulation of Shareholders’ Resolutions

Under the Singapore Companies Act, (a) any number of shareholders 
representing not less than 5% of the total voting rights of all the 
shareholders having at the date of requisition a right to vote at a meeting to 
which the requisition relates or (b) not less than 100 shareholders holding 
shares on which there has been paid up an average sum, per shareholder, of 
not less than S$500, may requisition the company to give to shareholders 
notice of any resolution which may properly be moved and is intended to 
be moved at the next annual general meeting, and circulate to shareholders 
any statement of not more than 1,000 words with respect to the matter 
referred to in any proposed resolution or the business to be dealt with at 
that meeting.

Under Section 172 of the Singapore Companies Act, any provision 
exempting or indemnifying the officers of a company (including directors) 
against liability, which by law would otherwise attach to them in 
connection with any negligence, default, breach of duty or breach of trust in 
relation to the company is void.

However, the Singapore Companies Act allows a company to:

•      purchase and maintain for any officer insurance against any 

liability which by law would otherwise attach to such officer in 
connection with any negligence, default, breach of duty or 
breach of trust in relation to the company;

•      indemnify such officer against any liability incurred by him or 

her to a person other than the company 

11

 
 
   
 
 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
   
 
 
 
 
 
 
Delaware

    Singapore

•      acted in good faith and in a manner he or she reasonably 

believed to be in or not opposed to the best interests of the 
corporation or, in some circumstances, at least not opposed to 
its best interests; and

•      in a criminal proceeding, had no reasonable cause to believe his 

or her conduct was unlawful.

Delaware corporate law permits indemnification by a corporation under 
similar circumstances for expenses (including attorneys’ fees) actually and 
reasonably incurred by such persons in connection with the defense or 
settlement of a derivative action or suit, except that no indemnification may 
be made in respect of any claim, issue or matter as to which the person is 
adjudged to be liable to the corporation unless the Delaware Court of 
Chancery or the court in which the action or suit was brought determines 
upon application that the person is fairly and reasonably entitled to 
indemnity for the expenses which the court deems to be proper.

To the extent a director, officer, employee or agent is successful in the 
defense of such an action, suit or proceeding, the corporation is required by 
Delaware corporate law to indemnify such person for reasonable expenses 
incurred thereby. Expenses (including attorneys’ fees) incurred by such 
persons in defending any action, suit or proceeding may be paid in advance 
of the final disposition of such action, suit or proceeding upon receipt of an 
undertaking by or on behalf of that person to repay the amount if it is 
ultimately determined that that person is not entitled to be so indemnified.

except when the indemnity is against any liability (i) of the 
officer to pay a fine in criminal proceedings, (ii) of the officer 
to pay a penalty in respect of non-compliance with any 
regulatory requirements, (iii) incurred by the officer in 
defending criminal proceedings in which he or she is convicted, 
(iv) incurred by the officer in defending civil proceedings 
brought by the company or a related company in which 
judgment is given against him or her, or (v) incurred by the 
officer in connection with an application for relief under 
Section 76A(13) or Section 391 of the Singapore Companies 
Act in which the court refuses to grant him or her relief.

In cases where a director is sued by the company, the Singapore Companies 
Act gives the court the power to relieve directors either wholly or partially 
from their liability for their negligence, default, breach of duty or breach of 
trust. In order for relief to be obtained, it must be shown that (i) the director 
acted reasonably and honestly; and (ii) it is fair, having regard to all the 
circumstances of the case including those connected with such director’s 
appointment, to excuse the director. However, Singapore case law has 
indicated that such relief will not be granted to a director who has benefited 
as a result of his or her breach of trust.

Our constitution provides that subject to the provisions of the Singapore 
Companies Act and every other applicable statute for the time being in 
force concerning companies and affecting the company, the directors and 
officers are entitled to be indemnified against costs, charges, fees and other 
expenses that may be incurred by such person in defending any 
proceedings, whether civil or criminal, which relates to anything done or 
omitted or alleged to be done or omitted by such person as a director, 
officer or employee of the company and in which judgment is given in his 
or her favor or in which such person is acquitted or in which the courts 
have granted relief pursuant to the provisions of the Singapore Companies 
Act, provided that such indemnity shall not extend to any liability which by 
law would otherwise attach to him or her in respect of any negligence, 
default, breach of duty or breach of trust of which he or she may be guilty 
in relation to the company, or which would otherwise result in such 
indemnity being voided under applicable Singapore laws.

Shareholder Approval of Issuances of Shares

Under Delaware law, the board of directors has the authority to issue, from 
time to time, capital stock in its sole discretion, as long the number the 
shares to be issued, together with those shares that are already issued and 
outstanding and those shares reserved to be issued, do not exceed the 
authorized capital for the corporation as previously approved by the 
stockholders and set forth in the corporation’s certificate of incorporation. 
Under the foregoing circumstances, no additional stockholder approval is 
required for the issuance of capital stock. Under Delaware law, stockholder 
approval is required (i) for any amendment to the corporation’s certificate 
of incorporation to increase the authorized capital and (ii) for the issuance 
of stock in a direct merger transaction where the number of shares exceeds 
20% of 

Section 161 of the Singapore Companies Act provides that despite anything 
in the company’s constitution, the directors must not exercise any power to 
issue shares without prior approval of Company’s shareholders in a general 
meeting. The affirmative vote of shareholders holding at least a majority of 
the ordinary shares held by the shareholders present in person or 
represented by proxy at the annual general meeting and entitled to vote is 
required for this authorization. Once this shareholders’ approval is 
obtained, unless previously revoked or varied by the company in general 
meeting, it continues in force until the conclusion of the next annual 
general meeting or the expiration of the period within which the next 
annual general meeting after that date is required by law to be held, 
whichever is earlier; but any approval may be revoked or varied by the 
company in general meeting.

Notwithstanding this general authorization to allot and issue our ordinary 
shares, Wave will be required to seek shareholder approval with respect to 
future issuances of ordinary shares, where required under The Nasdaq 
Stock Market rules, such as if we were to propose an issuance of ordinary 
shares that would result in a change in control of Wave or in connection 
with certain transactions involving the issuance of ordinary shares 
representing 20% or more of our outstanding ordinary shares.

Shareholder Approval of Business Combinations

Generally, under the Delaware General Corporation Law, completion of a 
merger, consolidation, or the sale, lease or exchange of substantially all of a 
corporation’s assets or dissolution requires approval by the board of 
directors and by a majority (unless the certificate of incorporation requires a 
higher percentage) of outstanding stock of the corporation entitled to vote.

The Delaware General Corporation Law also requires a special vote of 
stockholders in connection with a business combination with an “interested 
stockholder” as defined in section 203 of the Delaware General Corporation 
Law. See “—Interested Shareholders” above.

Shareholder Action Without A Meeting

Under the Delaware General Corporation Law, unless otherwise provided 
in a corporation’s certificate of incorporation, any action that may be taken 
at a meeting of stockholders may be taken without a meeting, without prior 
notice and without a vote if the holders of outstanding stock, having not 
less than the minimum number of votes that would be necessary to 
authorize such action, consent in writing. It is not uncommon for a 
corporation’s certificate of incorporation to prohibit such action.

Shareholder Suits

The Singapore Companies Act and the Insolvency, Restructuring and 
Dissolution Act 2018 mandates that specified corporate actions require 
approval by the shareholders in a general meeting, notably:

•      despite anything in the company’s constitution, directors must 

not carry into effect any proposals for disposing of the whole or 
substantially the whole of the company’s undertaking or 
property unless those proposals have been approved by 
shareholders in a general meeting;

•      the company may by special resolution resolve that it be wound 

up voluntarily;

•      subject to the constitution of each amalgamating company, an 
amalgamation proposal must be approved by the shareholders 
of each amalgamating company via special resolution at a 
general meeting;

•      a compromise or arrangement proposed between a company 
and its shareholders, or any class of them, must, among other 
things, be approved by a majority in number representing three-
fourths in value of the shareholders or class of shareholders 
present and voting either in person or by proxy at the meeting 
ordered by the court; and

•      despite anything in the company’s constitution, the directors 
must not, without the prior approval of shareholders, issue 
shares, including shares being issued in connection with 
corporate actions.

There are no equivalent provisions under the Singapore Companies Act in 
respect of public companies which are listed on a securities exchange, like 
our company.

Under the Delaware General Corporation Law, a stockholder may bring a 
derivative action on behalf of the corporation to enforce the rights of the 
corporation. An individual also may commence a class action suit on behalf 
of himself or herself and other 

Standing

Only registered shareholders of our company reflected in our register of 
members are recognized under Singapore law as shareholders of our 
company. As a result, only registered

Delaware
similarly situated stockholders where the requirements for maintaining a 
class action under the Delaware General Corporation Law have been met. 
A person may institute and maintain such a suit only if such person was a 
stockholder at the time of the transaction which is the subject of the suit or 
his or her shares thereafter devolved upon him or her by operation of law. 
Additionally, under Delaware case law, the plaintiff generally must be a 
stockholder not only at the time of the transaction which is the subject of 
the suit, but also through the duration of the derivative suit. The Delaware 
General Corporation Law also requires that the derivative plaintiff make a 
demand on the directors of the corporation to assert the corporate claim 
before the suit may be prosecuted by the derivative plaintiff, unless such 
demand would be futile.

    Singapore

shareholders have legal standing to institute shareholder actions against us 
or otherwise seek to enforce their rights as shareholders. Holders of book-
entry interests in our shares will be required to exchange their book-entry 
interests for certificated shares and to be registered as shareholders in our 
shareholder register in order to institute or enforce any legal proceedings or 
claims against us, our directors or our executive officers relating to 
shareholder rights. A holder of book-entry interests may become a 
registered shareholder of our company by exchanging its interest in our 
shares for certificated shares and being registered in our shareholder 
register.

Personal remedies in cases of oppression or injustice

A shareholder may apply to the court for an order under Section 216 of the 
Singapore Companies Act to remedy situations where (i) the company’s 
affairs are being conducted or the powers of the company’s directors are 
being exercised in a manner oppressive to, or in disregard of the interests of 
one or more of the shareholders or holders of debentures of the company, 
including the applicant; or (ii) the company has done an act, or threatens to 
do an act, or the shareholders or holders of debentures have passed some 
resolution, which unfairly discriminates against, or is otherwise prejudicial 
to, one or more of the company’s shareholders or holders of debentures, 
including the applicant.

Singapore courts have wide discretion as to the relief they may grant under 
such application, including, inter alia, directing or prohibiting any act or 
cancelling or varying any transaction or resolution, providing that the 
company be wound up, or authorizing civil proceedings to be brought in 
the name of or on behalf of the company by such person or persons and on 
such terms as the court directs.

Derivative actions and arbitrations

The Singapore Companies Act has a provision which provides a 
mechanism enabling shareholders to apply to the court for leave to bring a 
derivative action or commence an arbitration on behalf of the company. 
Derivative actions are also allowed as a common law action.

Applications are generally made by shareholders of the company, but 
courts are given the discretion to allow such persons as they deem proper to 
apply (e.g., beneficial owner of shares).

It should be noted that this provision of the Singapore Companies Act is 
primarily used by minority shareholders to bring an action or arbitration in 
the name and on behalf of the company or intervene in an action or 
arbitration to which the company is a party for the purpose of prosecuting, 
defending or discontinuing the action or arbitration on behalf of the 
company. Prior to commencing a derivative action or arbitration, the court 
must be satisfied that (i) 14 days’ notice has been given to the directors of 
the company of the party’s intention to commence such action or arbitration 
if the directors of the company do not bring, diligently prosecute or defend 
or discontinue the action, (ii) the party is acting in good faith and (iii) it 
appears to be prima facie in the interests of the company that the action be 
brought, prosecuted, defended or discontinued.

Class actions

Distributions and Dividends; Repurchases and Redemptions

The Delaware General Corporation Law permits a corporation to declare 
and pay dividends out of statutory surplus or, if there is no surplus, out of 
net profits for the fiscal year in which the dividend is declared and/or for 
the preceding fiscal year as long as the amount of capital of the corporation 
following the declaration and payment of the dividend is not less than the 
aggregate amount of the capital represented by the issued and outstanding 
stock of all classes having a preference upon the distribution of assets.

Under the Delaware General Corporation Law, any corporation may 
purchase or redeem its own shares, except that generally it may not 
purchase or redeem these shares if the capital of the corporation is impaired 
at the time or would become impaired as a result of the redemption. A 
corporation may, however, purchase or redeem out of capital shares that are 
entitled upon any distribution of its assets to a preference over another class 
or series of its shares if the shares are to be retired and the capital reduced.

The concept of class action suits in the United States, which allows 
individual shareholders to bring an action seeking to represent the class or 
classes of shareholders, does not exist in the same manner in Singapore. In 
Singapore, it is possible as a matter of procedure for a number of 
shareholders who have a common interest in any proceedings, to begin 
proceedings as a group with one or more of such shareholders representing 
the group.

The Singapore Companies Act provides that no dividend is payable to the 
shareholders of any company except out of profits.

The Singapore Companies Act does not provide a definition on when 
profits are deemed to be available for the purpose of paying dividends and 
this is accordingly governed by case law.

Our constitution provides that no dividend can be paid otherwise than out 
of profits.

Acquisition of a company’s own shares

The Singapore Companies Act generally prohibits a company from 
acquiring its own shares or purporting to acquire the shares of its holding 
company or ultimate holding company, whether directly or indirectly, in 
any way, subject to certain exceptions. Any contract or transaction made or 
entered into in contravention of the aforementioned prohibition by which a 
company acquires or purports to acquire its own shares or shares in its 
holding company or ultimate holding company is void. However, provided 
that it is expressly permitted to do so by its constitution and subject to the 
special conditions of each permitted acquisition contained in the Singapore 
Companies Act, a company may:

•      redeem redeemable preferred shares on such terms and in such 
manner as is provided by its constitution. Preferred shares may 
be redeemed out of capital only if all the directors make a 
solvency statement in relation to such redemption in 
accordance with the Singapore Companies Act, and the 
company lodges a copy of the statement with the Registrar of 
Companies;

•     whether listed on an exchange in Singapore approved by the 
Monetary Authority of Singapore or any securities exchange 
outside Singapore, or not, make an off-market purchase of its 
own shares in accordance with an equal access scheme 
authorized in advance at a general meeting;

•      make a selective off-market purchase of its own shares in 
accordance with an agreement authorized in advance at a 
general meeting by a special resolution where persons whose 
shares are to be acquired and their associated persons have 
abstained from voting; and

15

 
 
 
   
 
 
 
 
 
 
Delaware

    Singapore

•     whether listed on an exchange in Singapore approved by the 
Monetary Authority of Singapore or any securities exchange 
outside Singapore, or not, make an acquisition of its own shares 
under a contingent purchase contract which has been 
authorized in advance at a general meeting by a special 
resolution.

A company may also purchase its own shares by an order of a Singapore 
court.

•     The total number of ordinary shares, stocks in any class and 
non-redeemable preferred shares that may be acquired by a 
company in a relevant period must not exceed 20% (or such 
other prescribed percentage) of the total number of ordinary 
shares, stocks in any class or non-redeemable preferred shares 
(as the case may be) as of the date of the resolution to acquire 
the shares. Where, however, a company has reduced its share 
capital by a special resolution or a Singapore court made an 
order to such effect, the total number of ordinary shares, stocks 
in any class or non-redeemable preferred shares shall be taken 
to be the total number of ordinary shares, stocks in any class or 
non-redeemable preferred shares (as the case may be) as altered 
by the special resolution or the order of the court. Payment, 
including any expenses (including brokerage or commission) 
incurred directly in the acquisition by the company of its own 
shares, may be made out of the company’s profits or capital, 
provided that the company is solvent.

Financial assistance for the acquisition of shares

A public company or a company whose holding company or ultimate 
holding company is a public company must not give financial assistance to 
any person whether directly or indirectly for the purpose of or in 
connection with:

•      the acquisition or proposed acquisition of shares in the 

company or units of such shares; or

•      the acquisition or proposed acquisition of shares in its holding 
company or ultimate holding company, or units of such shares.

Financial assistance may take the form of a loan, the giving of a guarantee, 
the provision of security, the release of an obligation, the release of a debt 
or otherwise.

However, it should be noted that a company may provide financial 
assistance for the acquisition of its shares or shares in its holding company 
or ultimate holding company if it complies with the requirements 
(including approval by special resolution) set out in the Singapore 
Companies Act.

Our constitution provides that subject to the provisions of the Singapore 
Companies Act, we may purchase or otherwise acquire our own shares 
upon such terms and subject to such conditions as we may deem fit. We 
may deal with any such shares which is so purchased or acquired by us in 
such manner as may be permitted 

16

    Singapore

under the Singapore Companies Act (including, without limitation, hold 
such shares as treasury shares).

Transactions with Officers or Directors

Under the Delaware General Corporation Law, some contracts or 
transactions in which one or more of a corporation’s directors has an 
interest are not void or voidable because of such interest provided that some 
conditions, such as obtaining the required approval and fulfilling the 
requirements of good faith and full disclosure, are met. Under the Delaware 
General Corporation Law, either (a) the stockholders or the board of 
directors of a corporation must approve in good faith any such contract or 
transaction after full disclosure of the material facts or (b) the contract or 
transaction must have been “fair” as to the corporation at the time it was 
approved. If board approval is sought, the contract or transaction must be 
approved in good faith by a majority of disinterested directors after full 
disclosure of material facts, even though less than a majority of a quorum.

17

Under the Singapore Companies Act, directors and the chief executive 
officer of the company are not prohibited from dealing with the company, 
but where they have an interest, whether directly or indirectly, in a 
transaction with the company, that interest must be disclosed to the board 
of directors. In particular, every director or chief executive officer who is in 
any way, whether directly or indirectly, interested in a transaction or 
proposed transaction with the company must, as soon as is practicable after 
the relevant facts have come to such director’s or, as the case may be, the 
chief executive officer’s knowledge, declare the nature of such interest at a 
meeting of the directors or send a written notice to the company detailing 
the nature, character and extent of the interest.

In addition, a director or chief executive officer who holds any office or 
possesses any property which directly or indirectly might create interests in 
conflict with such director’s or, as the case may be, the chief executive 
officer’s duties as director or chief executive officer is required to declare 
the fact and the nature, character and extent of the conflict at a meeting of 
directors or send a written notice to the company detailing the nature, 
character and extent of the conflict.

The Singapore Companies Act extends the scope of this statutory duty of a 
director and chief executive officer to disclose any interests by pronouncing 
that an interest of a member of a director’s or, as the case may be, the chief 
executive officer’s family (including spouse, son, adopted son, step-son, 
daughter, adopted daughter and step-daughter) will be treated as an interest 
of the director or chief executive officer (as the case may be).

A director or chief executive officer is not deemed to be interested or to 
have been at any time interested in any transaction or proposed transaction 
where the interest of the director or chief executive officer (as the case may 
be) consists only of being a member or creditor of a corporation which is 
interested in the transaction or proposed transaction with the company if 
the interest may properly be regarded as immaterial. Where the transaction 
or the proposed transaction relates to any loan to the company, no 
disclosure need be made where the director or chief executive officer (as 
the case may be) has only guaranteed the repayment of such loan, unless 
the constitution provides otherwise.

Further, where any transaction or proposed transaction has been or will be 
made with or for the benefit of or on behalf of a related corporation (i.e., 
the holding company, subsidiary or subsidiary of a common holding 
company), the director or chief executive officer is not deemed to be 
interested or to have been at any time interested in such transaction or 
proposed transaction by virtue of only being a director or chief executive 
officer (as the case may be) of the related corporation, unless the 
constitution provides otherwise.

    Singapore

Subject to specified exceptions, the Singapore Companies Act prohibits a 
company (other than an exempt private company) from, among others, (i) 
making a loan or a quasi-loan to its directors or to directors of a related 
corporation, or giving a guarantee or security in connection with such a 
loan or quasi-loan, (ii) entering into a credit transaction as creditor for the 
benefit of its directors or the directors of a related corporation, or giving a 
guarantee or any security in connection with such a credit transaction, (iii) 
arranging an assignment to or assumption by us of any rights, obligations 
or liabilities under a transaction which, if it had been entered into by us, 
would have been a restricted transaction, and (iv) taking part in an 
arrangement under which another person enters into a transaction which, if 
entered into by us, would have been a restricted transaction and such 
person obtains a benefit from us or our related corporation pursuant thereto. 
Companies are also prohibited from entering into any of these transactions 
with the spouse or children (whether adopted or natural or step-children) of 
its directors.

Subject to specified exceptions, the Singapore Companies Act prohibits a 
company (other than an exempt private company) from making a loan or a 
quasi-loan to another company or a limited liability partnership or entering 
into any guarantee or providing any security in connection with a loan or a 
quasi-loan made to another company or a limited liability partnership by a 
person other than the first-mentioned company, entering into a credit 
transaction as a creditor for the benefit of another company or a limited 
liability partnership, or entering into any guarantee or provide any security 
in connection with a credit transaction entered into by any person for the 
benefit of another company or a limited liability partnership if a director or 
directors of the first-mentioned company is or together are interested in 
20% or more of the total voting power in the other company or the limited 
liability partnership (as the case may be).

Such prohibition also applies to a loan or quasi-loan made by a company 
(other than an exempt private company), a credit transaction made by a 
company (other than an exempt private company) for the benefit of another 
company or limited liability partnership and a guarantee entered into or 
security provided by a company (other than an exempt private company) in 
connection with a loan or quasi-loan made by a person other than the first-
mentioned company to another company or a limited liability partnership or 
with a credit transaction made for the benefit of another company or limited 
liability partnership entered into by a person other than the first-mentioned 
company, where such other company or limited liability partnership is 
incorporated or formed (as the case may be) outside Singapore, if a director 
or directors of the first-mentioned company (a) is or together are interested 
in 20% or more of the total voting power in the other company or limited 
liability partnership or (b) in a case where the other company does not have 
a share capital, exercises or together exercise control over the other 
company whether by reason of having the power to appoint directors or 
otherwise.

The Singapore Companies Act also provides that an interest of a member of 
a director’s family (including spouse, son, adopted son, step-son, daughter, 
adopted daughter and step-daughter) will be treated as an interest of the 
director.

Dissenters’ Rights

    Singapore

Under the Delaware General Corporation Law, a stockholder of a 
corporation participating in some types of major corporate transactions 
may, under varying circumstances, be entitled to appraisal rights pursuant 
to which the stockholder may receive cash in the amount of the fair market 
value of his or her shares in lieu of the consideration he or she would 
otherwise receive in the transaction.

Cumulative Voting

Under the Delaware General Corporation Law, a corporation may adopt in 
its bylaws that its directors shall be elected by cumulative voting. When 
directors are elected by cumulative voting, a stockholder has the number of 
votes equal to the number of shares held by such stockholder times the 
number of directors nominated for election. The stockholder may cast all of 
such votes for one director or among the directors in any proportion.

THIS  COLLABORATION  AND  LICENSE  AGREEMENT  (this  “Agreement”),  entered  into  as  of  December  13,  2022  (the 
“Execution Date”), is entered into by and among Wave Life Sciences USA, Inc., a corporation organized and existing under the Laws of the 
State of Delaware (“Wave US”), Wave Life Sciences UK Limited, a private limited company incorporated under the laws of England and

under the laws of England, with offices at 980 Great West Road, Brentford, Middlesex, TW8 9GS (“GSK”).  Wave and GSK are referred to 
in this Agreement individually as a “Party” and collectively as the “Parties.” 

RECITALS:

WHEREAS,  Wave  is  a  genetic  medicine  company  focused  on  advancing  Oligonucleotides  that  precisely  target  the  underlying 

causes of diseases; 

WHEREAS, GSK possesses expertise in developing and commercializing therapeutics;

3.3.1 for entry into the research collaboration (such schedule, the “Target List”).  The Target List [***].  The Target List 
indicates  each  Target  [***].    The  Target  List  may  be  updated  from  time  to  time  in  accordance  with  the  gatekeeper 
provisions set forth in Section 3.3.2 (Gatekeeper).  

3.3.2 

Gatekeeper.  

3.3.2.1  Gatekeeper.  The Parties have engaged [***] to serve as a gatekeeper for the research collaboration under this 
Agreement  (the  “Gatekeeper”)  through  which  GSK  may  inquire  as  to  whether  any  Target  that  GSK  would 
like to add to the Target List is available for inclusion in the research collaboration at such time (i.e., is not an
Unavailable Target).  

3.3.2.2  Gatekeeper Procedures.  

(a)  During  the  Research  Term,  GSK  may,  at  its  discretion,  submit  written  inquiries  to  the  Gatekeeper  to  
determine  if  a  Target  is  available  for  inclusion  as  a  Target  [***]  under  this  Agreement  (each,  a 
“Proposed Target”); provided, for clarity, that (i) GSK will comply with the parameters on Targets as 
set  forth  in  Section  3.4.2  (Parameters  for  Target  Validation  Programs);  and  (ii)  Targets  may  not  be 
added  [***]  after  the  Execution  Date.    GSK’s  written  inquiry  to  the  Gatekeeper  for  each  Proposed 
Target will include the following information (each, a “Proposed Target Notice”): (1) the identity of 
such  Proposed  Target  (which  includes  the  NCBI  Gene  ID  for  known  targets),  and  if  no  such  NCBI 
Gene ID exists then an unequivocal identifier of such target, and, if applicable, whether such Proposed 
Target is a[***]. 

(b)  Upon receipt of a Proposed Target Notice, the Gatekeeper will notify Wave as soon as practicable of such 
inquiry  by  GSK  without  disclosing  the  identity  of  the  Proposed  Target,  after  which  Wave  will  have 
[***]  to  provide  the  Gatekeeper  a  then-current  list  of  Unavailable  Targets,  [***]  (which  includes  the 
NCBI Gene ID for known targets), and if no such NCBI Gene ID exists then an unequivocal identifier 
of such target.  Within [***] of receipt of the list of Unavailable Targets from Wave, the Gatekeeper 
will inform GSK in writing whether the Proposed Target is available.  

(i) 

If  the  Gatekeeper  informs  GSK  that  a  Proposed  Target  is  an  Unavailable  Target,  then  such  
Proposed  Target  will  not  become  a  Target  on  the  Target  List,  and  the  Parties  will  have  no 
further obligations under this Agreement with respect to such Target.  

(ii)  If the Gatekeeper confirms that a Proposed Target is available for inclusion on the Target List (i.e., 
not  an  Unavailable  Target)  (an  “Available  Proposed  Target”),  then  the  Gatekeeper  will 
provide written notice to both Parties, specifying all of the information that was included in 
the  Proposed  Target  Notice  (such  notice,  the  “Available  Proposed  Target  Notice”).  
Following the Parties’ receipt of an Available Proposed Target Notice from the 

‑35‑

  
 
 
Gatekeeper,  the  Parties  will  update  [***]  Target  List[***]  to  include  the  new  Target  and  its 
identity (including the NCBI Gene ID for known targets), and if no such NCBI Gene ID exists 
then an unequivocal identifier of such target, and, [***].

7.7  Bankruptcy.    All  rights  and  licenses  granted  under  or  pursuant  to  this  Agreement  by  a  Party  to  the  other  are  and  will  otherwise  be 
deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of right to “intellectual property” as defined under 
Section 101 of the Bankruptcy Code.  The Parties agree that the Parties and their respective Sublicensees, as Sublicensees of such 
rights under this Agreement, will retain and may fully exercise all of their rights and elections under the Bankruptcy Code and any 
foreign counterpart thereto.  The Parties further agree that upon commencement of a bankruptcy proceeding by or against a Party 
(the “Bankrupt Party”) under the Bankruptcy Code, the other Party (the “Non‑Bankrupt Party”) will be entitled to a complete 
duplicate  of,  or  complete  access  to  (as  the  Non‑Bankrupt  Party  deems  appropriate),  all  such  intellectual  property  and  all 
embodiments  of  such  intellectual  property.    Such  intellectual  property  and  all  embodiments  of  such  intellectual  property  will  be 
promptly  delivered  to  the  Non‑Bankrupt  Party  (a)  upon  any  such  commencement  of  a  bankruptcy  proceeding  and  upon  written 
request  by  the  Non‑Bankrupt  Party,  unless  the  Bankrupt  Party  elects  to  continue  to  perform  all  of  its  obligations  under  this 
Agreement, or (b) if not delivered under clause (a) above, upon the rejection of this Agreement by or on behalf of the Bankrupt 
Party and upon written request by the Non‑Bankrupt Party.  The Bankrupt Party (in any capacity, including debtor‑in‑possession) 
and  its  successors  and  assigns  (including  any  trustee)  agree  not  to  interfere  with  the  exercise  by  the  Non‑Bankrupt  Party  or  its 
Related Parties of its rights and licenses to such intellectual property and such embodiments of intellectual property in accordance 
with this Agreement, and agrees to assist the Non‑Bankrupt Party and its Related Parties in obtaining such intellectual property and 
such embodiments of intellectual property in the possession or Control of Third Parties as are reasonably necessary or desirable for 
the  Non‑Bankrupt  Party  to  exercise  such  rights  and  licenses  in  accordance  with  this  Agreement.    The  foregoing  provisions  are

‑66‑

  
 
 
8.7.1 

SERPINA1 Specific Patents. 

8.7.1.1  During the Term, Wave or its Affiliates will have the first right, but not the obligation, in consultation with the 
JPC, to Prosecute and Maintain in all jurisdictions in the Territory the SERPINA1 Specific Patents (the “Lead 
SERPINA1  Patent  Party”).    The  Lead  SERPINA1  Patent  Party  will  [***].    The  Lead  SERPINA1  Patent 
Party will have lead responsibility and decision-making control for such Prosecution and Maintenance of the 
SERPINA1  Specific  Patents.    For  clarity,  (i)  where  the  JPC  is  unable  to  reach  consensus  regarding  any 
Prosecution and Maintenance related decision for a SERPINA1 Specific Patent, the Lead SERPINA1 Patent 
Party will have final decision-making authority with respect to such decision; and (ii) each Party will bear its 
own internal costs (i.e., those costs that are not Patent Costs) with respect to its Prosecution and Maintenance 
activities for the SERPINA1 Specific Patents.

8.7.1.2 

In  the  event  that  the  Lead  SERPINA1  Patent  Party  elects  not  to  Prosecute  and  Maintain  in  any  country  any 
SERPINA1 Specific Patent, such Lead SERPINA1 Patent Party will give the other Party at least [***] notice 
before any relevant deadline and provide to such other Party information it reasonably requests relating to the 
SERPINA1  Specific  Patent,  and  such  other  Party  will  then  have  the  right  to  request  the  Lead  SERPINA1 
Patent Party to continue the Prosecution and Maintenance of such SERPINA1 Specific Patent.  [***].

8.7.1.3  Each  Party  will  provide  the  other  Party  all  reasonable  assistance  and  cooperation  in  the  Prosecution  and 
Maintenance of the SERPINA1 Specific Patents in all respects, including providing any necessary powers of 
attorney and executing any other required documents or instruments for such Prosecution and Maintenance, as 
necessary to Prosecute and Maintain the SERPINA1 Specific Patents.  Each Party will provide the other Party 
with  copies  of  any  documents  it  receives  or  prepares  in  connection  with  such  Prosecution  and  Maintenance 
and will inform the other Party of the progress of it.  Before filing in connection with such Prosecution and 
Maintenance any document with a patent office, each Party will provide a copy of the document to the other 
Party  sufficiently  in  advance  to  enable  the  other  Party  to  comment  on  it,  and  the  first  Party  will  give  due 
consideration  to  such  comments  and  will  reasonably  incorporate  any  of  such  comments  in  the  first  Party’s 
filings or responses to the extent such comments are provided sufficiently in advance of any applicable filing 
deadlines.    In  particular,  each  Party  agrees  to  provide  the  other  Party  with  all  information  necessary  or 
desirable  to  enable  the  other  Party  to  comply  with  the  duty  of  candor/duty  of  disclosure/duty  of  reasonable 
inquiry requirements of any patent authority.

8.7.1.4 

The  Parties  will  confer  regarding  the  desirability  of  seeking  in  any  country  any  patent  term  extension, 
supplemental patent certificate or related extension of rights with respect to the SERPINA1 Specific Patents.  
The  Lead  SERPINA1  Patent  Party  will  have  the  sole  right,  but  not  the  obligation,  to  apply  for  any  such 
extension  or  supplemental  patent  certificate  or  related  extension  of  rights  with  respect  to  the  SERPINA1 
Specific Patents.  Neither Party will proceed with such an extension until the Parties have consulted with one 
another  and  agreed  to  a  strategy  therefor,  provided  that  in  the  case  where  the  Parties  are  unable  to  reach 
consensus, the Lead SERPINA1 Patent Party will have the final decision making 

‑67‑

  
 
 
authority  with  respect  to  such  decision,  including  whether  or  not  to  seek  an  extension  for  any  SERPINA1 
Specific  Patent.    Without  limiting  the  foregoing,  the  Party  that  is  not  the  Lead  SERPINA1  Patent  Party 
covenants that it will not seek patent term extensions, supplemental protection certificates, or similar rights or 
extensions  for  the  SERPINA1  Specific  Patents  without  the  prior  written  consent  of  the  Lead  SERPINA1 
Patent Party.  Each Party will cooperate fully with and provide all reasonable assistance to the other Party and 
use all commercially reasonable efforts consistent with its obligations under Applicable Law (including any 
applicable  consent  order  or  decree)  in  connection  with  obtaining  any  such  extensions  for  the  SERPINA1 
Specific Patents consistent with such strategy.  To the extent reasonably and legally required in order to obtain 
any such extension in a particular country, each Party will make available to the other a copy of the necessary 
documentation to enable such other Party to use the same for the purpose of obtaining the extension in such 
country. 

8.7.2 

GSK CP Specific Patents.

8.7.2.1  GSK will have the first right, but not the obligation, in consultation with the JPC, to Prosecute and Maintain in 
all jurisdictions in the Territory the GSK CP Specific Patents.  Subject to Section 8.7.2.2, GSK will bear one 
hundred  percent  (100%)  of  the  Patent  Costs  for  the  GSK  CP  Specific  Patents.    GSK  will  have  lead 
responsibility  and  decision-making  control  for  such  Prosecution  and  Maintenance  of  the  GSK  CP  Specific 
Patents.    For  clarity,  (i)  where  the  JPC  is  unable  to  reach  consensus  regarding  any  Prosecution  and 
Maintenance related decision for a GSK CP Specific Patent, GSK will have final decision-making authority 
with respect to such decision within the scope of the GSK CP Specific Patent; and (ii) each Party will bear its 
own internal costs (i.e., those costs that are not Patent Costs) with respect to its Prosecution and Maintenance 
activities for the GSK CP Specific Patents.

8.7.2.2 

In the event that GSK elects not to Prosecute and Maintain in any country any GSK CP Specific Patent, GSK 
will  give  Wave  at  least  [***]  notice  before  any  relevant  deadline  and  provide  to  Wave  information  it 
reasonably  requests  relating  to  the  GSK  CP  Specific  Patent,  and  Wave  will  then  have  the  right  to  assume 
responsibility,  using  patent  counsel  of  its  choice,  for  the  Prosecution  and  Maintenance  of  such  GSK  CP 
Specific Patent.  If Wave assumes responsibility for the Prosecution and Maintenance for any such GSK CP 
Specific Patent as set forth above, then (a) the Patent Costs incurred by Wave in the course of such Prosecution 
and  Maintenance  will  thereafter  be  borne  by  Wave,  and  (b)  if  such  GSK  CP  Specific  Patent  is  in  the  Wave 
Technology, then (i) such Patent will thereafter be deemed to be a Wave Other Patent and (ii) GSK’s license 
rights with respect to such Patent (and any continuation or divisional thereof) under Section 7.3 (GSK CPs) 
will become non-exclusive. 

8.7.2.3  Each  Party  will  provide  the  other  Party  all  reasonable  assistance  and  cooperation  in  the  Prosecution  and 
Maintenance  of  the  GSK  CP  Specific  Patents  in  all  respects,  including  providing  any  necessary  powers  of 
attorney and executing any other required documents or instruments for such Prosecution and Maintenance, as 
necessary to Prosecute and Maintain the GSK CP Specific Patents.  Each Party will provide the other Party 
with  copies  of  any  documents  it  receives  or  prepares  in  connection  with  such  Prosecution  and  Maintenance 
and 

‑68‑

  
 
 
8.7.2.4 

will  inform  the  other  Party  of  the  progress  of  it.    Before  filing  in  connection  with  such  Prosecution  and 
Maintenance any document with a patent office, each Party will provide a copy of the document to the other 
Party  sufficiently  in  advance  to  enable  the  other  Party  to  comment  on  it,  and  the  first  Party  will  give  due 
consideration  to  such  comments  and  will  reasonably  incorporate  any  of  such  comments  in  the  first  Party’s 
filings or responses to the extent such comments are provided sufficiently in advance of any applicable filing 
deadlines.    In  particular,  each  Party  agrees  to  provide  the  other  Party  with  all  information  necessary  or 
desirable to enable the other Party to comply with the duty of candor/duty of disclosure requirements of any 
patent authority.

The  Parties  will  confer  regarding  the  desirability  of  seeking  in  any  country  any  patent  term  extension, 
supplemental  patent  certificate  or  related  extension  of  rights  with  respect  to  the  GSK  CP  Specific  Patents. 
GSK will have the sole right, but not the obligation, to apply for any such extension or supplemental patent 
certificate  or  related  extension  of  rights  with  respect  to  the  GSK  CP  Specific  Patents.    Neither  Party  will 
proceed  with  such  an  extension  until  the  Parties  have  consulted  with  one  another  and  agreed  to  a  strategy 
therefor, provided that in the case where the Parties are unable to reach consensus, GSK will have the final 
decision making authority with respect to such decision, including whether or not to seek an extension for any 
GSK  CP  Specific  Patent.  Without  limiting  the  foregoing,  Wave  covenants  that  it  will  not  seek  patent  term 
extensions,  supplemental  protection  certificates,  or  similar  rights  or  extensions  for  the  GSK  CP  Specific 
Patents  without  the  prior  written  consent  of  GSK.    Each  Party  will  cooperate  fully  with  and  provide  all 
reasonable  assistance  to  the  other  Party  and  use  all  commercially  reasonable  efforts  consistent  with  its 
obligations  under  Applicable  Law  (including  any  applicable  consent  order  or  decree)  in  connection  with 
obtaining any such extensions for the GSK CP Specific Patents consistent with such strategy.  To the extent 
reasonably and legally required in order to obtain any such extension in a particular country, each Party will 
make available to the other a copy of the necessary documentation to enable such other Party to use the same 
for the purpose of obtaining the extension in such country. 

8.7.3  Wave CP Specific Patents.

8.7.3.1  Wave will have the first right, but not the obligation, in consultation with the JPC, to Prosecute and Maintain in 
all jurisdictions in the Territory the Wave CP Specific Patents.  Subject to Section 8.7.3.2, Wave will bear one 
hundred  percent  (100%)  of  the  Patent  Costs  for  the  Wave  CP  Specific  Patents.    Wave  will  have  lead 
responsibility  and  decision-making  control  for  such  Prosecution  and  Maintenance  of  the  Wave  CP  Specific 
Patents.    For  clarity,  (i)  where  the  JPC  is  unable  to  reach  consensus  regarding  any  Prosecution  and 
Maintenance related decision for a Wave CP Specific Patent, Wave will have final decision-making authority 
with respect to such decision; and (ii) each Party will bear its own internal costs (i.e., those costs that are not 
Patent Costs) with respect to its Prosecution and Maintenance activities for the Wave CP Specific Patents.

8.7.3.2 

In the event that Wave elects not to Prosecute and Maintain in any country any Wave CP Specific Patent, Wave 
will give GSK at least [***] notice before any relevant deadline and provide to GSK information it reasonably 
requests relating to the Wave CP Specific Patent, and GSK will then have the right to assume 

‑69‑

  
 
 
responsibility,  using  patent  counsel  of  its  choice,  for  the  Prosecution  and  Maintenance  of  such  Wave  CP 
Specific Patent.  If GSK assumes responsibility for the Prosecution and Maintenance for any such Wave CP
Specific Patent as set forth above, then (a) the Patent Costs incurred by GSK in the course of such Prosecution 
and  Maintenance  will  thereafter  be  borne  by  GSK,  and  (b)  if  such  Wave  CP  Specific  Patent  is  in  the  GSK 
Technology, then (i) such Patent will thereafter be deemed to be a GSK Other Patent and (ii) Wave’s license 
rights with respect to such Patent (and any continuation or divisional thereof) under Section 7.4 (Wave CPs) 
will become non-exclusive. 

8.7.3.3  Each  Party  will  provide  the  other  Party  all  reasonable  assistance  and  cooperation  in  the  Prosecution  and 
Maintenance  of  the  Wave  CP  Specific  Patents  in  all  respects,  including  providing  any  necessary  powers  of 
attorney and executing any other required documents or instruments for such Prosecution and Maintenance, as 
necessary to Prosecute and Maintain the Wave CP Specific Patents.  Each Party will provide the other Party 
with  copies  of  any  documents  it  receives  or  prepares  in  connection  with  such  Prosecution  and  Maintenance 
and will inform the other Party of the progress of it.  Before filing in connection with such Prosecution and 
Maintenance any document with a patent office, each Party will provide a copy of the document to the other 
Party  sufficiently  in  advance  to  enable  the  other  Party  to  comment  on  it,  and  the  first  Party  will  give  due 
consideration  to  such  comments  and  will  reasonably  incorporate  any  of  such  comments  in  the  first  Party’s 
filings or responses to the extent such comments are provided sufficiently in advance of any applicable filing 
deadlines.    In  particular,  each  Party  agrees  to  provide  the  other  Party  with  all  information  necessary  or 
desirable to enable the other Party to comply with the duty of candor/duty of disclosure requirements of any 
patent authority.

8.7.3.4 

The  Parties  will  confer  regarding  the  desirability  of  seeking  in  any  country  any  patent  term  extension, 
supplemental  patent  certificate  or  related  extension  of  rights  with  respect  to  the  Wave  CP  Specific  Patents. 
Wave will have the sole right, but not the obligation, to apply for any such extension or supplemental patent 
certificate  or  related  extension  of  rights  with  respect  to  the  Wave  CP  Specific  Patents.    Neither  Party  will 
proceed  with  such  an  extension  until  the  Parties  have  consulted  with  one  another  and  agreed  to  a  strategy 
therefor, provided that in the case where the Parties are unable to reach consensus, Wave will have the final 
decision making authority with respect to such decision, including whether or not to seek an extension for any 
Wave  CP  Specific  Patent.  Without  limiting  the  foregoing,  GSK  covenants  that  it  will  not  seek  patent  term 
extensions,  supplemental  protection  certificates,  or  similar  rights  or  extensions  for  the  Wave  CP  Specific 
Patents  without  the  prior  written  consent  of  Wave.    Each  Party  will  cooperate  fully  with  and  provide  all 
reasonable  assistance  to  the  other  Party  and  use  all  commercially  reasonable  efforts  consistent  with  its 
obligations  under  Applicable  Law  (including  any  applicable  consent  order  or  decree)  in  connection  with 
obtaining any such extensions for the Wave CP Specific Patents consistent with such strategy.  To the extent 
reasonably and legally required in order to obtain any such extension in a particular country, each Party will 
make available to the other a copy of the necessary documentation to enable such other Party to use the same 
for the purpose of obtaining the extension in such country.

Additional Provisions.  The Parties acknowledge and agree that, except with respect to GSK Background Patents and 
Wave Background Patents that exists prior to the date that a Target is added to the Target List, neither Party will Prosecute 
or Maintain any Patent that Covers (a) a Target on a Target List or (b) a Validation Target, in each case ((a)-(b)) until such 
Target or Validation Target becomes a GSK Collaboration Target or Wave Collaboration Target or a Declined Target, as 
applicable, in accordance with Section 3.4.9 (Advancement to Collaboration Program).

Third Party Patent Challenges.  Subject to Section 8.10 (Patent Challenges by Third Parties), the Parties agree that if a 
Third  Party  files  a  Third  Party  Patent  Challenge  in  front  of  a  patent  office  against  any  Patents  that  are  Prosecuted  and 
Maintained in accordance with this Section, the Parties shall defend such Patent in accordance with this Section, provided 
that if a Party requests assistance from the other Party with the defense, the Party that requests the assistance shall pay the 
cost  and  expenses  incurred  by  the  other  Party  for  providing  the  requested  assistance,  which  assistance  shall  not  be 
unreasonably withheld, conditioned or delayed.

Consent  for  Characterization.     Notwithstanding  anything  to  the  contrary  set  forth  in  this  Agreement,  during  the 
Prosecution  and  Maintenance  in  accordance  with  this  Section  8.7  (Prosecution  and  Maintenance),  (i)  a  Party  or  its

unreasonably withheld, conditioned or delayed.

8.8  Enforcement.

8.8.1 

Notification.  On a Collaboration Program-by-Collaboration Program basis, the Parties will promptly notify each other, 
through the JSC, JDC and the JPC, of any actual, threatened or alleged infringement by a Third Party of the SERPINA1 
Specific Patents, GSK CP Specific Patents or Wave CP Specific Patents with respect to any Third Party products targeting, 
modulating  or  otherwise  directed  to  the  Collaboration  Target  for  such  Collaboration  Program  in  the  Territory  (a 
“Competitive Infringement”).    A  notice  under  42  U.S.C.  262(l)  (however  such  section  may  be  amended  from  time  to 
time during the Term) with respect to a Collaboration Compound or Collaboration Product will be deemed to describe an 
act of Competitive Infringement, regardless of its content.  As permitted by 

‑71‑

  
 
 
Applicable Law, each Party will promptly notify the other Party in writing, through the JSC, JDC and the JPC, of any such 
Competitive Infringement of which it becomes aware, and will provide evidence in such Party’s possession demonstrating 
such  Competitive  Infringement.  In  particular,  each  Party  will  notify  and  provide  the  other  Party  with  copies  of  any 
allegations of patent invalidity, unenforceability or non-infringement of any SERPINA1 Specific Patents, GSK Specific 
Patents or Wave Specific Patents Covering a Collaboration Compound or Collaboration Product (including methods of use 
or manufacture thereof).  The JPC will discuss in good faith strategies for abating such Competitive Infringement.  Such 
notification and copies will be provided by the Party receiving such certification to the JPC as soon as practicable and, 
unless prohibited by Applicable Law, at least within [***] after the receiving Party receives such certification.  

8.8.2 

SERPINA1 Specific Patents.  

8.8.2.1  GSK will have the first right, but not the obligation, to bring and control, at its cost and expense, an appropriate 
suit or other action before any government or private tribunal against any person or entity allegedly engaged in 
any  Competitive  Infringement  of  any  SERPINA1  Specific  Patent  (“SERPINA1  Infringement  Action”)  to 
remedy  such  Competitive  Infringement  (or  to  settle  or  otherwise  secure  the  abatement  of  such  Competitive 
Infringement).  The foregoing right of GSK will include the right to perform all actions of a reference product 
sponsor set forth in 42 U.S.C. § 262(l).  Wave will have the right, at its own cost and expense and by counsel 
of its choice, to be represented in (but not control) any SERPINA1 Infringement Action. At GSK’s request, 
Wave will join any SERPINA1 Infringement Action as a party (all at GSK’s cost and expense) if doing so is 
necessary for the purposes of establishing standing or is otherwise required by Applicable Law to pursue such 
action.  GSK will have a period of [***] after its receipt or delivery of notice and evidence pursuant to Section 
8.8.1  (Notification)  to  elect  to  so  enforce  such  SERPINA1  Specific  Patents  in  the  applicable  jurisdiction  to 
remedy  the  Competitive  Infringement  (or  to  settle  or  otherwise  secure  the  abatement  of  such  Competitive 
Infringement),  provided,  however,  that  such  period  will  be  more  than  [***]  to  the  extent  Applicable  Law 
prevents earlier enforcement of such SERPINA1 Specific Patents (such as the enforcement process set forth in 
42 U.S.C. § 262(l)) and such period will be less than [***] to the extent that a delay in bringing an action to 
enforce the applicable SERPINA1 Specific Patents against such alleged Third Party infringer would limit or 
compromise the remedies (including monetary and injunctive relief) available against such alleged Third Party 
infringer.  In the event GSK does not so elect to remedy the Competitive Infringement (or settle or otherwise 
secure  the  abatement  of  such  Competitive  Infringement)  within  the  aforementioned  period  of  time  or  [***]
before the time limit, if any, for the filing of a SERPINA1 Infringement Action, whichever is sooner, it will so 
notify Wave in writing and in the case where Wave then desires to commence a suit or take action to enforce
the  applicable  SERPINA1  Specific  Patents  with  respect  to  such  Competitive  Infringement  (or  settle  or 
otherwise  secure  the  abatement  of  such  Competitive  Infringement)  in  the  applicable  jurisdiction,  the  Parties 
will confer and, upon GSK’s prior written consent (not to be unreasonably withheld, conditioned or delayed), 
Wave will have the right to commence such a suit or take such action to enforce the applicable SERPINA1 
Specific Patents with respect to such Competitive Infringement (or settle or otherwise secure the abatement of 
such Competitive Infringement), at Wave’s cost and expense.  Each 

‑72‑

  
 
 
Party  will  provide  to  the  Party  enforcing  any  such  rights  under  this  Section  8.8.2.1  reasonable  assistance  in 
such enforcement, at such enforcing Party’s request and cost and expense, including joining such action as a 
party plaintiff if required by Applicable Law to pursue such action. The enforcing Party will keep the other 
Party regularly informed of the status and progress of such enforcement efforts, and will reasonably consider 
the other Party’s comments on any such efforts.

8.8.2.2  Without the prior written consent of the other Party (not to be unreasonably withheld, conditioned or delayed), 
neither  Party  will  settle  any  SERPINA1  Infringement  Action  in  any  manner  that  would  adversely  affect  a 
SERPINA1  Specific  Patent;  provided,  that  GSK  will  have  the  right  to  grant  (sub)licenses  under  the 
SERPINA1  Specific  Patents  in  its  sole  discretion  and  Wave  will  reasonably  cooperate  with  such  efforts 
(including by granting any license to GSK to effect the same) or that would limit or restrict the ability of GSK 
(or  its  Affiliates  or  its  or  their  Sublicensees,  as  applicable)  to  sell  SERPINA1  Products  anywhere  in  the 
Territory. 

8.8.2.3  A  Party  bringing  a  SERPINA1  Infringement  Action  under  this  Section  8.8.2  (SERPINA1  Specific  Patents) 
against any Third Party engaged in Competitive Infringement of the SERPINA1 Specific Patents will be solely 
responsible  for  any  costs  and  expenses  incurred  by  such  Party  as  a  result  of  such  SERPINA1  Infringement 
Action.  If  such  Party  recovers  monetary  damages  from  such  Third  Party  in  such  SERPINA1  Infringement 
Action, such recovery [***].

any Competitive Infringement of any GSK CP Specific Patent (“GSK CP Infringement Action”) to remedy 
such  Competitive  Infringement  (or  to  settle  or  otherwise  secure  the  abatement  of  such  Competitive 
Infringement).  The foregoing right of GSK will include the right to perform all actions of a reference product 
sponsor set forth in 42 USC 262(l).  Wave will have the right, at its own cost and expense and by counsel of its 
choice, to be represented in (but not control) any GSK CP Infringement Action. At GSK’s request, Wave will 
join any GSK CP Infringement Action as a party (all at GSK’s cost and expense) if doing so is necessary for 
the purposes of establishing standing or is otherwise required by Applicable Law to pursue such action.  GSK 
will  have  a  period  of  [***]  after  its  receipt  or  delivery  of  notice  and  evidence  pursuant  to  Section  8.8.1 
(Notification) to elect to so enforce such GSK CP Specific Patents in the applicable jurisdiction to remedy the 
Competitive Infringement (or to settle or otherwise secure the abatement of such Competitive Infringement), 
provided,  however,  that  such  period  will  be  more  than  [***]  to  the  extent  Applicable  Law  prevents  earlier 
enforcement  of  such  GSK  CP  Specific  Patents  (such  as  the  enforcement  process  set  forth  in  42  U.S.C.  § 
262(l))  and  such  period  will  be  less  [***]  to  the  extent  that  a  delay  in  bringing  an  action  to  enforce  the 
applicable GSK CP Specific Patents against such alleged Third Party infringer would limit or compromise the 
remedies (including monetary and injunctive relief) available against such alleged Third Party infringer.  In the 
event GSK does not so elect

to  remedy  the  Competitive  Infringement  (or  settle  or  otherwise  secure  the  abatement  of  such  Competitive 
Infringement) within the aforementioned period of time or [***] before the time limit, if any, for the filing of a 
GSK  CP  Infringement  Action,  whichever  is  sooner,  it  will  so  notify  Wave  in  writing  and  in  the  case  where 
Wave then desires to commence a suit or take action to enforce the applicable GSK CP Specific Patents with 
respect  to  such  Competitive  Infringement  (or  settle  or  otherwise  secure  the  abatement  of  such  Competitive 
Infringement) in the applicable jurisdiction, the Parties will confer and, upon GSK’s prior written consent (not 
to be unreasonably withheld, conditioned or delayed), Wave will have the right to commence such a suit or 
take  such  action  to  enforce  the  applicable  GSK  CP  Specific  Patents  with  respect  to  such  Competitive 
Infringement (or settle or otherwise secure the abatement of such Competitive Infringement), at Wave’s cost 
and  expense.    Each  Party  will  provide  to  the  Party  enforcing  any  such  rights  under  this  Section  8.8.3.1
reasonable assistance in such enforcement, at such enforcing Party’s request and cost and expense, including 
joining  such  action  as  a  party  plaintiff  if  required  by  Applicable  Law  to  pursue  such  action.  The  enforcing 
Party will keep the other Party regularly informed of the status and progress of such enforcement efforts, and 
will reasonably consider the other Party’s comments on any such efforts.

8.8.3.2  Without the prior written consent of the other Party (not to be unreasonably withheld, conditioned or delayed), 
neither Party will settle any GSK CP Infringement Action in any manner that would adversely affect a GSK 
CP Specific Patent; provided, that GSK will have the right to grant (sub)licenses under the GSK CP Specific 
Patents in its sole discretion and Wave will reasonably cooperate with such efforts (including by granting any 
license to GSK to effect the same) or that would limit or restrict the ability of GSK (or its Affiliates or its or 
their Sublicensees, as applicable) to sell GSK Collaboration Products anywhere in the Territory. 

8.8.3.3  A Party bringing a GSK CP Infringement Action under this Section 8.8.3 (GSK CP Specific Patents) against any 
Third Party engaged in Competitive Infringement of the GSK CP Specific Patents will be solely responsible

such action to enforce the applicable Wave CP Specific Patents with respect to such Competitive Infringement 
(or settle or otherwise secure the abatement of such Competitive Infringement), at GSK’s cost and expense.  
Each Party will provide to the Party enforcing any such rights under this Section 8.8.4.1 reasonable assistance

Party regularly informed of the status and progress of such enforcement efforts, and will reasonably consider 
the other Party’s comments on any such efforts.

8.8.4.2  Without the prior written consent of the other Party (not to be unreasonably withheld, conditioned or delayed), 
neither Party will settle any Wave CP Infringement Action in any manner that would adversely affect a Wave 
CP Specific Patent; provided, that Wave will have the right to grant (sub)licenses under the Wave CP Specific

9.10.2  Reports and Royalty Payments.  Commencing upon the First Commercial Sale of a Collaboration Product and 
continuing  for  as  long  as  Royalties  are  due  under  Section  9.8  (Royalties),  within  [***]  after  each  Calendar 
Quarter ending on March 31, June 30, September 30 or December 31, GSK will furnish to Wave a written report 
that includes the following information for such Calendar Quarter on a Collaboration Product-by-Collaboration 
Product and country-by-country basis:  (a) [***] (each, a “Royalty Report”).  All such reports will be treated as 
Confidential Information of GSK. GSK shall pay to Wave the royalties payable under this Section with respect to 
a given Calendar Quarter within [***] following the end of each Calendar Quarter together with delivery of the 
applicable Royalty Report.  

9.10.3  Records; Audits.

9.10.3.1  GSK will, and will ensure that its Related Parties (as applicable), keep complete and accurate records 
in accordance with its record retention policies applicable to such books and records, but in any event 
for a period of at least [***] after the end of the Calendar Year in which any such payment becomes 
payable, in sufficient detail to confirm the accuracy of the calculations hereunder and in accordance 
with the applicable Accounting Standard that is normally applied by such Party with respect to the 
filing of its reporting.

9.10.3.2  During the Term and for [***] thereafter, GSK will permit, and will cause its Related Parties to permit, 
an independent certified public accounting firm of nationally recognized standing selected by Wave, 
and  reasonably  acceptable  to  GSK  or  such  Related  Party  to  have  access  to  and  to  review,  during 
normal  business  hours  and  under  obligations  of  confidentiality  at  least  as  protective  of  GSK 
Confidential Information as the confidentiality provisions of Section 10 (Confidentiality) and upon 
[***]  prior  written  notice,  no  more  frequently  than  [***]  period  (except  in  the  case  of  fraud),  to 
verify  the  accuracy  of  the  Royalty  Reports  and  payments  under  this  Section  9  (Payments)  with 
respect to any Calendar Year ending not more than [***] prior to such audit request.  The accounting 
firm will disclose to GSK and Wave only whether the Royalty Reports are correct or incorrect and 
the specific details concerning any discrepancies.  If such accounting firm concludes that additional 
amounts were owed during such period, and GSK agrees with such calculation, GSK will promptly 
pay the additional undisputed amount.  If such accounting firm concludes that an overpayment was 
made,  such  overpayment  will  be  fully  creditable  against  amounts  payable  in  subsequent  payment 
periods.  Wave will pay for the cost of any audit, unless GSK has underpaid Wave by [***] or more 
for the audited period. Each Party will treat all information that it receives under this Section 9.10.3.2 
in accordance with the confidentiality provisions of Section 10 (Confidentiality), and will cause its 
accounting firm to enter into an acceptable, reasonable confidentiality agreement with the other Party 
obligating  such  firm  to  retain  all  such  financial  information  in  confidence  pursuant  to  such 
confidentiality  agreement,  except  to  the  extent  necessary  for  such  Party  to  enforce  its  rights  under 
this Agreement.

9.10.4  Currency Exchange.  With respect to Net Sales of Collaboration Products invoiced in Dollars, the Net Sales, 
Royalties,  and  other  amounts  due  to  Wave  hereunder  will  be  expressed  in  Dollars.    When  conversion  of 
payments  from  any  foreign  currency  is  required  to  be  undertaken  by  GSK,  the  Dollar  equivalent  will  be 
calculated using [***] for the conversion of foreign currency sales into Dollars.

9.10.5  Taxes.

9.10.5.1  VAT.  It is understood and agreed between the Parties that any payments made under this Agreement 
are exclusive of VAT.  Where VAT is properly added to a payment made under this Agreement, the 
Party making the payment will pay the amount of such VAT only on receipt of a valid Tax invoice 
(or, where there is no provision in the legislation for the jurisdiction concerned that a VAT invoice is 
required  to  be  issued,  a  written  demand  containing  such  information  as  is  customary  in  that 
jurisdiction) issued in accordance with the Applicable Laws and regulations of the country in which 
the VAT is chargeable.

9.10.5.2  Withholding Taxes.  In the event any payments made pursuant to this Agreement become subject to 
withholding  Taxes  under  the  Applicable  Law  or  regulations  of  any  jurisdiction,  the  Party  making 
such payment will deduct and withhold the amount of such Taxes for the account of the payee to the 
extent  required  by  Applicable  Law  and  such  amounts  payable  to  the  payee  will  be  reduced  by  the 
amount  of  Taxes  deducted  and  withheld.    Any  such  withholding  Taxes  required  under  Applicable 
Law to be paid or withheld will be an expense of, and borne solely by, the payee, and the payee will 
indemnify and hold harmless the Party making any payment pursuant to this Agreement for any such 
withholding  Taxes  (including,  for  the  avoidance  of  doubt,  any  additional  amounts  of  Taxes  later 
determined  by  a  Tax  Authority  to  have  been  required  to  be  withheld);  provided,  however,  that  the 
Party  making  such  payment  will  not  be  entitled  to  indemnification  for  any  penalties  or  other 
additions to Tax arising solely as a result of such Party’s failure to timely remit the applicable Taxes 
in  accordance  with  the  Tax  forms  provided  by  the  payee  pursuant  to  Section  9.10.5.5  (Tax 
Cooperation).

9.10.5.3  No Other Reductions.    Apart  from  any  such  permitted  withholding  and  those  deductions  expressly 
included  in  the  definition  of  Net  Sales,  the  amounts  payable  hereunder  will  not  be  reduced  on 
account of any Taxes, unless required by Applicable Law.

9.10.5.4  Tax  Exemptions  and  Credits .    The  Parties  will  cooperate  with  each  other  in  seeking  any  tax 
exemption or credits that may be available with respect to any Collaboration Product, including the 
tax credit available under Section 45C of the Internal Revenue Code by reason of a Party’s research 
and development expenditures contributing to the Collaboration Product being granted orphan drug 
status by the FDA, or equivalent foreign Applicable Law.

9.10.5.5  Tax Cooperation.  To the extent that the Party making a payment is required to deduct and withhold 

Taxes on any payments under this 

‑88‑

  
 
 
Agreement,  the  Party  making  such  payment  will  pay  the  amounts  of  such  Taxes  to  the  proper  Tax 
Authority in a timely manner and promptly transmit to the payee an official Tax certificate or other 
evidence of such withholding sufficient to enable the payee to claim such payments of Taxes.  To the 
extent  that  the  Party  making  a  payment  under  this  Agreement  is  required  to  deduct  and  withhold 
Taxes  on  any  such  payment,  such  Party  will  provide  the  payee  with  written  notice  of  the  required 
withholding  as  promptly  as  reasonably  practical  (and  in  any  event,  no  later  than  [***]  prior  to 
making  such  payment  and  will  cooperate  with  the  payee  as  provided  in  this  Section  9.10.5.5  (Tax 
Cooperation)  in  order  to  mitigate  the  imposition  of  such  withholding  Taxes,  and  the  payee  will 
provide any Tax forms to the Party making such payment that may be reasonably necessary in order 
for such Party not to withhold Tax or to withhold Tax at a reduced rate under an applicable bilateral 
income Tax treaty.  The payee will use reasonable efforts to provide any such Tax forms to the Party 
making the payment at least [***] prior to the due date for any payments for which the payee desires 
that  the  Party  making  the  payment  apply  a  reduced  withholding  rate.    Each  Party  will  provide  the 
other  with  reasonable  assistance  to  enable  the  recovery,  as  permitted  by  Applicable  Law,  of 
withholding Taxes, VAT, or similar obligations resulting from payments made under this Agreement, 
such recovery to be for the benefit of the Party bearing such withholding Tax or VAT.

9.10.5.6  Withholding Indemnification and Reimbursement.  Notwithstanding anything in this Agreement to 
the contrary, if an action (including any assignment or sublicense of its rights or obligations under 
this Agreement to any Person that is tax resident in a jurisdiction other than the jurisdiction of the 
Party taking such action, or any failure to comply with Applicable Laws or filing or record retention 
requirements)  by  a  Party  leads  to  the  imposition  of  withholding  Tax  liability  or  VAT  on  the  other 
Party  that  would  not  have  been  imposed  in  the  absence  of  such  action  or  in  an  increase  in  such 
liability above the liability that would have been imposed in the absence of such action, such Party 
will indemnify and hold harmless the other Party from any such additional or increased withholding 
Tax liability or VAT (except to the extent that the other Party can reclaim it, provided that such other 
Party will be reimbursed for any reasonable Out-of-Pocket costs incurred in the reclaim).

9.10.5.7  Wave US Treaty Eligibility: 

(a)  Wave US warrants that Wave US is resident for tax purposes in the United States of America and that Wave 
US is entitled to relief from United Kingdom income Tax under the terms of the double tax agreement 
between  the  United  Kingdom  and  the  United  States  of  America.    Wave  US  shall  notify  GSK 
immediately in writing in the event that Wave US ceases to be entitled to such relief. 

(b)  Pending receipt of formal certification from the UK Tax Authority, GSK may pay royalty income and any 

other payments under this Agreement to 

‑89‑

  
 
 
Wave US by deducting tax at a rate specified in the double tax treaty between the United Kingdom and 
the United States of America.  

9.10.6  Blocked Payments.  In the event that, by reason of Applicable Law in any country, it becomes impossible or 
illegal for a Party to transfer, or have transferred on its behalf, payments owed the other Party hereunder, such 
Party will promptly notify the other Party of the conditions preventing such transfer and such payments will be 
deposited  in  local  currency  in  the  relevant  country  to  the  credit  of  the  other  Party  in  a  recognized  banking 
institution designated by the other Party or, if none is designated by the other Party within a period of [***], in a 
recognized banking institution selected by the transferring Party, as the case may be, and identified in a written 
notice given to the other Party.

9.10.7 

Interest Due.  Each paying Party will pay the other Party interest on any undisputed payments that are not paid 
on or before the date such payments are due under this Agreement at the per annum rate of [***] over the then 
current secured overnight financing rate for the payment currency published by the [***] on the date it falls due 
or the maximum rate allowable by Applicable Law, whichever is lower.

9.10.8  Wave  Payments  to  GSK .    The  payment  terms  in  this  Section  9.10  (Payment  Terms)  will  apply  to  payments 

made by Wave to GSK on Wave Collaboration Products, mutatis mutandis.

10.  CONFIDENTIALITY

10.1 Confidentiality Obligations.  Except as expressly permitted by this Agreement, each Party agrees that during the Term and for ten (10) 
years thereafter, such Party will, and will ensure that its Affiliates and its and their respective Personnel (“Representatives”), hold 
in  confidence  all  Confidential  Information  disclosed  to  it  by  the  other  Party  pursuant  to  this  Agreement  (or  the  Existing 
Confidentiality Agreement, as applicable).  The Receiving Party will not disclose any of the Confidential Information, except to its 
Representatives who need to know the Confidential Information for the purpose of performing the Receiving Party’s obligations, or 
exercising its rights, under this Agreement and who are bound by obligations of non-use and non-disclosure substantially similar to 
those set forth herein. The Receiving Party will be responsible for any disclosure or use of the Confidential Information in breach of 
its obligations hereunder by such Representatives. The Receiving Party will protect Confidential Information using not less than the 
same care with which it treats its own confidential information, but at all times will use at least reasonable care. Each Party will: (i) 
implement  and  maintain  appropriate  security  measures  to  prevent  unauthorized  access,  disclosure  or  use  of  the  other  Party’s 
Confidential  Information;  (ii)  promptly  notify  the  other  Party  of  any  unauthorized  access  or  disclosure  of  such  other  Party’s 
Confidential Information (and, in the case of Wave as the Receiving Party, will send an e-mail to csir@gsk.com); and (iii) cooperate 
with  such  other  Party  in  good  faith  in  connection  with  the  investigation  and  remediation  of  any  such  unauthorized  access  or 
disclosure.  The existence and terms of this Agreement and the Equity Agreements are the Confidential Information of each Party.  
All  information  exchanged  between  the  Parties  regarding  the  Prosecution  and  Maintenance  and  enforcement  and  defense  of  the 
Patents under Section 8 (Intellectual Property) will be the Confidential Information of the Disclosing Party.

10.2 Exceptions to Confidentiality. The obligations of nondisclosure and non‑use set forth in Section 10.1 (Confidentiality Obligations) will 

not apply to the extent that such Confidential Information:

‑90‑

  
 
 
10.2.1 

is or becomes generally available to the public other than as a result of improper disclosure by the Receiving 
Party;

10.2.2 

is already known by or in the possession of the Receiving Party at the time of disclosure by the Disclosing Party, 
and  not  through  a  prior  disclosure  by  the  Disclosing  Party  as  documented  by  the  Receiving  Party’s 
contemporaneously dated written business records;

10.2.3 

is  independently  developed  by  the  Receiving  Party  without  use  of  or  reference  to  the  Disclosing  Party’s 
Confidential  Information,  as  documented  by  the  Receiving  Party’s  contemporaneously  dated  written  business 
records; or

10.2.4 

is obtained by the Receiving Party from a Third Party that the Receiving Party believes, acting reasonably and in 
good faith, after due inquiry, has not breached any obligations of confidentiality as documented by the Receiving 
Party’s contemporaneously dated written business records.

10.3 Permitted Disclosures.  

10.3.1  Notwithstanding the obligations of confidentiality and non‑use set forth above, a Receiving Party may provide 
Confidential Information disclosed to it, and disclose the existence and terms of this Agreement or the Equity 
Agreements as may be reasonably required in order to perform its obligations and to exploit its licenses and other 
rights  under  this  Agreement,  and  specifically  to  (a)  Related  Parties,  and  their  employees,  directors,  agents, 
consultants,  or  advisors  to  the  extent  necessary  for  the  potential  or  actual  performance  of  its  obligations  or 
exercise  of  its  licenses  and  other  rights  under  this  Agreement  in  each  case  who  are  under  an  obligation  of 
confidentiality  with  respect  to  such  information  that  is  no  less  stringent  than  the  terms  of  this  Section  10.3 
(Permitted Disclosures); (b) Governmental Authorities or other Regulatory Authorities in order to obtain patents 
or perform its obligations or exploit its rights under this Agreement, provided that such Confidential Information 
will be disclosed only to the extent reasonably necessary to do so, and where permitted, subject to confidential 
treatment; (c) the extent required by Applicable Law, including by the rules or regulations of the United States 
Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of 
any stock exchange or listing entity; (d) with respect to the terms of this Agreement and the Equity Agreements 
only, any bona fide actual or prospective acquirers, underwriters, investors, lenders, or other financing sources 
and any bona fide actual or prospective collaborators, licensors, Sublicensees, licensees, or strategic partners and 
to employees, directors, agents, consultants, and advisers of any such Third Party, in each case, who are under 
obligations of confidentiality and non‑use with respect to such information that is no less stringent than the terms 
of this Section 10.3 (Permitted Disclosures) (but of duration customary in confidentiality agreements entered into 
for a similar purpose); and (e) to Third Parties to the extent a Party is required to do so pursuant to the terms of a 
Third Party Agreement.  

10.3.2 

In making any disclosures set forth in this Section 10.3 (Permitted Disclosures), the Receiving Party will, where 
reasonably  practicable,  give  such  advance  notice  to  the  Disclosing  Party  of  such  disclosure  requirement  as  is 
reasonable under the circumstances and will use its reasonable efforts to cooperate with the Disclosing 

‑91‑

  
 
 
10.3.3 

Party  in  order  to  secure  confidential  treatment  of  such  Confidential  Information  required  to  be  disclosed.    In 
addition,  in  connection  with  any  permitted  filing  by  either  Party  of  this  Agreement  with  any  Governmental 
Authority  the  Receiving  Party  will  (i)  endeavor  to  obtain  confidential  treatment  of  economic,  trade  secret  and 
such other information as may be requested by the Disclosing Party, (ii) provide the Disclosing Party with the 
proposed confidential treatment request within a reasonable time for the Disclosing Party to provide comments, 
and  the  Receiving  Party  will  consider  and  incorporate  such  comments  in  good  faith  in  connection  with  its 
submission  of  its  confidential  treatment  request,  and  (iii)  submit  the  proposed  disclosure  in  writing  to  the 
Disclosing  Party  as  far  in  advance  as  reasonably  practicable  so  as  to  provide  a  reasonable  opportunity  to 
comment thereon and the Receiving Party will incorporate such comments in good faith.

Notwithstanding  Section  10.1  (Confidentiality  Obligations)  and  Section  10.4  (Publications  and  Publicity), 
without limiting this Section 10.3 (Permitted Disclosures), (i) the Receiving Party may disclose the Confidential 
Information of the Disclosing Party to the extent required by Applicable Law or court order; provided, however, 
that  the  Receiving  Party  will  first  provide  the  Disclosing  Party  prior  notice  of  such  disclosure  and  give  the 
Disclosing  Party  a  reasonable  opportunity  to  quash  such  order  or  to  obtain  a  protective  order  or  confidential 
treatment  requiring  that  the  Confidential  Information  and  documents  that  are  the  subject  of  such  order  or 
required to be disclosed be held in confidence by such court or Governmental Authority or, if disclosed, be used 
only  for  the  purposes  for  which  the  order  was  issued  or  such  disclosure  was  required  by  Applicable  Law; 
provided,  further,  that  the  Confidential  Information  disclosed  in  response  to  such  order  or  as  required  by 
Applicable  Law  will  be  limited  to  the  information  that  is  legally  required  to  be  disclosed  in  response  to  such 
order  or  by  such  Applicable  Law;  and  (ii)  the  Receiving  Party  may  disclose  Confidential  Information  of  the 
Disclosing Party to the extent any such disclosure is, in the opinion of the Receiving Party’s counsel, required by 
Applicable Law or the rules of a stock exchange on which the securities of the Receiving Party are listed (or to 
which  an  application  for  listing  has  been  submitted);  provided  that,  in  the  event  the  Receiving  Party  is,  in  the 
opinion of its counsel, required by Applicable Law or the rules of a stock exchange on which its securities are 
listed  (or  to  which  an  application  for  listing  has  been  submitted)  to  make  such  a  public  disclosure,  such 
Receiving  Party  will  submit  the  proposed  disclosure  to  the  Disclosing  Party  as  far  in  advance  as  reasonably 
practicable so as to provide a reasonable opportunity to comment thereon.

agency, rights that would otherwise interfere or be inconsistent with GSK’s rights hereunder, and there are no agreements 
or  arrangements  to  which  Wave  or  any  of  its  Affiliates  is  a  party  relating  to  Wave  Technology  or  Collaboration 
Compounds or Collaboration Products directed to any Collaboration Target, that would (a) limit the rights granted to GSK 
under this Agreement or (b) restrict or result in a restriction on GSK’s ability to Exploit the Collaboration Compounds or

encumbrances that would conflict with the rights granted under this Agreement.

the Wave Background Know‑How.

11.2.7  Government Funding.  Neither Wave nor its Affiliates have entered into a government funding relationship that would 
result in rights to any Collaboration Compound or Collaboration Product directed to any Collaboration Target residing in 
the  US  Government,  National  Institutes  of  Health,  National  Institute  for  Drug  Abuse  or  other  agency,  and  the  licenses 
granted hereunder are not subject to overriding obligations to the US Government as set forth in Public Law 96 517 (35 
U.S.C. 200 204), as amended, or any similar obligations under the laws of any other country.

11.2.8  Validity  and  Enforceability .  The  issued  patents  within  the  Wave  Background  Patents  are  valid  and  enforceable  and 
have  been  diligently  prosecuted  and  maintained.    There  are  no  oppositions,  nullity  actions,  interferences,  inter  partes 
reexaminations,  inter  partes  reviews,  post  grant  reviews,  derivation  proceedings,  or  other  proceedings  pending  or 
threatened (but excluding office actions or similar communications issued by any Patent Offices in the ordinary course of 
prosecution of any patent application) that challenge the scope, validity, or enforceability of the Wave Background Patents.
Wave has filed and prosecuted patent applications within the Wave Background Patents in good faith and, has complied 
with all duties of disclosure with respect thereto.  Other than through filing of terminal disclaimers in the ordinary course 
of  patent  prosecution,  Wave  has  not  committed  any  act,  or  omitted  to  commit  any  act,  that  may  cause  the  Wave 
Background Patents to expire prematurely or be declared invalid or unenforceable.  Wave or its Affiliates have timely paid 
all application, registration, maintenance, and renewal fees in respect of the Wave Background Patents and have filed with 
the United States Patent and Trademark Office or any analogous foreign Governmental Authority (collectively, “Patent 
Offices”) all necessary documents and certificates for the purpose of maintaining such Wave Background Patents.

11.2.9  No Claims.  The owned Wave Technology and, to Wave’s knowledge, the in‑licensed Wave Technology is not subject to, 
any  judgment  or  settlement  that  would  reasonably  be  expected  to  materially  restrict  the  use  thereof  or  otherwise  would 
reasonably be expected to adversely affect the validity or enforceability thereof.  To Wave’s knowledge, no Third Party 
has infringed upon or misappropriated any Wave Technology.

11.2.10  Non‑Infringement.  To Wave’s knowledge, the Exploitation of any Collaboration Compound or Collaboration Product 
directed to any Collaboration Target, in each case, as contemplated hereunder does not infringe any valid patent rights of 
any Third Party.  There are no claims, demands, suits, proceedings, arbitrations, or other legal actions of any nature, civil, 
criminal, regulatory or otherwise, pending or, to Wave’s knowledge, threatened against Wave or any of its Related Parties 
alleging or asserting any of the foregoing.

11.2.11  Regulatory.

11.2.11.1  All Development of the SERPINA1 Compound or SERPINA1 Product conducted by or on behalf of Wave or

12.  INDEMNIFICATION 

12.1 Indemnification by GSK. Subject to the other provisions of this Section 12 (Indemnification), GSK will indemnify, defend and hold 

harmless Wave and its Affiliates and each of their respective 

‑100‑

  
 
 
Personnel  (collectively,  the  “Wave  Indemnitees”)  from  and  against  any  and  all  liability,  damage,  loss,  fines,  penalties,  cost  or 
expense (including reasonable attorneys’ fees) (“Losses”) incurred by or rendered against such Wave Indemnitee in connection with 
Third  Party  claims,  investigations,  demands  or  suits  (“Third  Party  Claims”)  to  the  extent  arising  out  of  or  resulting  from:  (a) 
GSK’s or any of its GSK Indemnitees’ gross negligence, reckless conduct or willful misconduct; (b) any breach by GSK of this 
Agreement  of  its  representations  and  warranties,  covenants  or  obligations  set  forth  in  this  Agreement;  or  (c)  to  the  extent  such 
Losses arise out of the Exploitation of Collaboration Compounds or Collaboration Products directed to any Collaboration Target by 
or  on  behalf  of  GSK  or  any  of  its  Related  Parties;  provided,  however,  that  GSK’s  obligations  pursuant  to  this  Section  12.1 
(Indemnification  by  GSK)  will  not  apply  to  the  extent  such  Losses  are  covered  by  Wave’s  obligations  under  Section  12.2 
(Indemnification by Wave). 

12.2 Indemnification by Wave. Subject to the other provisions of this Section 12 (Indemnification), Wave will indemnify, defend and hold 
harmless GSK, its Affiliates and each of their respective Personnel (collectively, the “GSK Indemnitees”)  from  and  against  any 
and all Losses incurred by or rendered against such GSK Indemnitee in connection with Third Party Claims to the extent arising out 
of  or  resulting  from:  (a)  Wave’s  or  any  of  Wave  Indemnitee’s  gross  negligence,  reckless  conduct  or  willful  misconduct;  (b)  any 
breach by Wave of this Agreement of its representations and warranties, covenants or obligations set forth in this Agreement; or (c) 
to  the  extent  such  Losses  arise  out  of  the  Exploitation  of  Collaboration  Compounds  or  Collaboration  Products  directed  to  any 
Collaboration Target by or on behalf of Wave or any of its Related Parties; provided, however, that Wave’s obligations pursuant to 
this Section 12.2 (Indemnification by Wave) will not apply to the extent that such Losses are covered by GSK’s obligations under 
Section 12.1 (Indemnification by GSK).  

12.3 Notification of Claims; Conditions to Indemnification Obligations.  

12.3.1  As a condition to a Party’s right to receive indemnification under this Section 12 (Indemnification) with respect 
to any Third Party Claim, it will: (i) promptly notify the other Party as soon as it becomes aware of a Third Party 
Claim for which indemnification may be sought pursuant hereto, provided that the failure to give such notice will 
not  relieve  the  indemnifying  Party  of  its  indemnity  obligation  hereunder  except  to  the  extent  that  such  failure 
materially prejudices the indemnifying Party; (ii) cooperate, and cause the individual indemnitees to cooperate, 
with the indemnifying Party in the defense, settlement or compromise of such Third Party Claim; and (iii) permit 
the indemnifying Party to control the defense, settlement or compromise of such Third Party Claim, including 
the right to select defense counsel. In no event, however, may the indemnifying Party compromise or settle any 
Third  Party  Claim  in  a  manner  which  admits  fault  or  negligence  on  the  part  of  the  indemnified  Party  or  any 
indemnitee  without  the  prior  consent  of  the  indemnified  Party.  Each  Party  will  reasonably  cooperate  with  the 
other  Party  and  its  counsel  in  the  course  of  the  defense  of  any  such  Third  Party  Claim,  such  cooperation  to 
include using reasonable efforts to provide or make available documents, information and witnesses. In any such 
proceeding, the indemnified Party will have the right to retain its own counsel, but the fees and expenses of such 
counsel will be at the expense of the indemnifying Party unless (A) the indemnifying Party and the indemnified 
Party  will  have  agreed  to  the  retention  of  such  counsel  or  (B)  the  named  parties  to  any  such  proceeding 
(including  any  impleaded  parties)  include  both  the  indemnifying  Party  and  the  indemnified  Party  and 
representation  of  both  Parties  by  the  same  counsel  would  be  inappropriate  due  to  actual  or  potential  differing 
interests between them.  All 

‑101‑

  
 
 
such  fees  and  expenses  of  the  indemnified  Party  by  application  of  the  foregoing  clause  (A)  or  (B)  will  be 
reimbursed by the indemnifying Party as they are incurred. The indemnifying Party will have no liability under 
this Section 12 (Indemnification) with respect to any such Third Party Claims settled or compromised without its 
prior written consent.

12.3.2 

In the event that notice of any Third Party Claim for indemnification under this Section 12 (Indemnification) has 
been  timely  given  within  the  applicable  survival  period,  the  representations,  warranties,  covenants  and 
agreements that are the subject of such indemnification will survive with respect to Third Party Claim until such 
time as such Third Party Claim is finally resolved.

12.4 Certain Limitations.

12.4.1 

In  any  case  where  an  indemnified  Party  recovers  from  Third  Parties  any  amount  in  respect  of  a  matter  with 
respect  to  which  an  indemnifying  Party  has  indemnified  it  pursuant  to  this  Section  12  (Indemnification),  such 
indemnified  Party  will  promptly  pay  over  to  the  indemnifying  Party  the  amount  so  recovered  (after  deducting 
therefrom the full amount of the expenses incurred by it in procuring such recovery), but not in excess of the sum 
of  (a)  any  amount  previously  so  paid  by  the  indemnifying  Party  to  or  on  behalf  of  the  indemnified  Party  in 
respect of such matter and (b)  any amount expended by the indemnifying Party in pursuing or defending any 
claim arising out of such matter.

12.4.2 

In  calculating  any  Losses,  there  will  be  deducted  any  insurance  recovery  in  respect  thereof  (and  no  right  of 
subrogation  will  accrue  hereunder  to  any  insurer),  less  any  current  or  prospective  costs  associated  with  such 
insurance recovery, and the Party seeking indemnification hereunder may pursue in its sole discretion, and will 
not be obligated to pursue, an insurance recovery to the extent available.

12.4.3 

Each Party agrees to take all reasonable steps to mitigate their respective Losses upon and after becoming aware 
of any event or condition which could reasonably be expected to give rise to any liability, damage, loss, cost or 
expense that is indemnifiable hereunder.

12.5 Limitation of Liability. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, TO THE MAXIMUM 
EXTENT  PERMITTED  BY  LAW,  EXCEPT  WITH  RESPECT  TO  (A)  EACH  PARTY’S  RESPECTIVE  INDEMNIFICATION

SUCH PARTY OR ANY REPRESENTATIVE OF SUCH PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE 
ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE OR WHETHER SUCH LOSS OR DAMAGE WAS

13.  TERM AND TERMINATION

13.1 Term and Expiration.  Subject to Section 14 (Effectiveness), the term of this Agreement (the “Term”) will commence on the Effective 
Date and, unless earlier terminated as provided in this Section 13 (Term and Termination), will continue in full force and effect on a 
Validation  Target-by-Validation  Target  or  Collaboration  Target-by-Collaboration  Target  basis 
and  Collaboration 
Product‑by‑Collaboration Product basis until: 

13.1.1  with respect to a Validation Target, the date on which such Validation Target becomes a Declined Target; and

13.1.2  with respect to a Collaboration Target, the Royalty Term has expired for all Collaboration Products directed to 

the applicable Collaboration Target in each country in the Territory.   

13.2 Termination for Convenience by GSK.  At any time during the Term, GSK may, at its convenience, terminate this Agreement:

13.2.1 

in its entirety upon [***] prior written notice to Wave;

on a Target-by-Target basis, with respect to any Target [***] prior notice to Wave.

13.3 Termination of Wave CPs.  

‑103‑

  
 
 
13.3.1 

At  any  time  during  the  Term,  Wave  may,  at  its  convenience,  terminate  this  Agreement  with  respect  to  a  Wave 

Collaboration Target, (i) upon [***] directed to such Wave Collaboration Target.

13.3.2 

For clarity, (a) GSK will have no right to terminate this Agreement with respect to a Wave Collaboration Target under 
Section 13.2 (Termination for Convenience by GSK) and (b) a termination of this Agreement in its entirety by GSK will 
not  result  in  a  termination  with  respect  to  any  Wave  Collaboration  Targets  or  Wave  CPs  for  such  Wave  Collaboration 
Targets.  

13.4 Termination for Patent Challenge.  Either Party has the right to terminate this Agreement on a Collaboration Target‑by‑Collaboration 
Target  basis,  upon  written  notice  to  the  other  Party  if  such  other  Party  or  its  Affiliates  or  Sublicensees  with  respect  to  such 
Collaboration  Target  directly  or  indirectly  challenges  in  a  legal  or  administrative  proceeding  the  patentability,  enforceability  or 
validity of any Patents within the Wave Technology (with respect to a challenge brought by GSK or its Affiliates or Sublicensees 
with respect to such Collaboration Target), any Patents within the GSK Technology (with respect to a challenge brought by Wave or 
its Affiliates or Sublicensees with respect to such Collaboration Target), or any Patents within the Joint Technology (with respect to 
a challenge brought by either Party or such Party’s Affiliates or Sublicensees with respect to such Collaboration Target), as the case 
may be, that Cover any Collaboration Compound or Collaboration Product directed to such Collaboration Target (each, a “Patent 
Challenge”); provided that (a) this Section 13.4 (Termination for Patent Challenge) will not apply to any such Patent Challenge that 
is first made by a Party or one of its Related Parties in defense of a claim of patent infringement brought by the other Party under 
the applicable Patent, (b) this Section 13.4 (Termination for Patent Challenge) will not apply in the event that an Affiliate of a Party 
that first become an Affiliate of a Party after the Effective Date in connection with a merger or acquisition event, where such an 
Affiliate of a Party was already engaged in a Patent Challenge prior to the signing of a definitive agreement in connection with such 
merger or acquisition event, so long as the Party causes such Patent Challenge to terminate within [***] after the closing of such 
merger or acquisition event, and (c) with respect to any non‑Affiliate Sublicensee, a Party will not have the right to terminate this 
Agreement under this Section 13.4 (Termination for Patent Challenge) with respect to any Collaboration Target if the other Party (i) 
causes  such  Patent  Challenge  to  be  terminated  or  dismissed  (or  in  the  case  of  ex‑parte  proceedings,  multi‑party  proceedings,  or 
other  Patent  Challenges  in  which  the  challenging  party  does  not  have  the  power  to  unilaterally  cause  the  Patent  Challenge  to  be 
withdrawn, causes such Sublicensee to withdraw as a party from such Patent Challenge and to cease actively assisting any other 
party to such Patent Challenge) or (ii) terminates such Sublicensee’s sublicense to the Patents being challenged by the Sublicensee, 
in each case, within [***] days of the terminating Party’s notice to the other Party under this Section 13.4 (Termination for Patent 
Challenge). 

13.5 Termination for Cause.

13.5.1  Right to Terminate for Material Breach.  Each Party (the “Non-Breaching Party”) will have the right, but 
not the obligation, to terminate this Agreement upon delivery of written notice to the other Party (the “Breaching 
Party”) on a Validation Target-by-Validation Target or Collaboration Target‑by‑Collaboration Target basis in the 
event of any material breach of this Agreement by the Breaching Party with respect to such Validation Target or 
Collaboration  Target  or  in  its  entirety  in  the  event  of  any  material  breach  of  this  Agreement  that  relates  to  all 
Validation Targets and Collaboration Targets, provided that such termination will not be effective if such breach 
has been cured [***] after written notice thereof is 

‑104‑

  
 
 
given by the Non-Breaching Party to the Breaching Party specifying the nature of the alleged breach (or, if such 
default  cannot  be  cured  within  such  first  [***]  such  termination  will  not  be  effective  if  such  breach  has  been
cured  within  [***]  (or  such  longer  period  of  time  as  the  Parties  may  mutually  agree)  after  such  notice  if  the 
Breaching  Party  commences  actions  to  cure  such  default  within  such  [***]  and  thereafter  diligently  continues 
such  actions);  provided,  however,  that  to  the  extent  such  material  breach  involves  the  failure  to  make  an 
undisputed payment when due, such breach must be cured within [***] after written notice thereof is given by 
the Non-Breaching Party to the Breaching Party.  

13.5.2  Disputed  Breach .    If  the  Breaching  Party  disputes  in  good  faith  the  existence  or  materiality  of  a  breach 
specified in a notice provided by the Non-Breaching Party in accordance with Section 13.5.1 (Right to Terminate 
for Material Breach) and such Breaching Party provides the Non-Breaching Party notice of such Dispute within 
such  [***],  then  the  cure  periods  set  forth  in  Section  13.5  (Termination  for  Cause)  will  be  tolled  during  the 
pendency of the dispute resolution process as set forth in Section 15 (Dispute Resolution) and the Non‑Breaching 
Party will not have the right to terminate this Agreement under Section 13.5.1 (Right to Terminate for Material 
Breach)  unless  and  until  such  dispute  resolution  process  has  been  completed  (including  the  tolling  and  cure 
periods set forth therein).

13.5.3 

[***].  

13.5.3.1  If GSK does not conduct, or cause to be conducted, [***] with respect to any SERPINA1 Product for a period of 
[***] at any time during the Term (the “[***]”), then, Wave will have the right to terminate this Agreement 
with respect to the SERPINA1 Target with [***] written notice to GSK, unless GSK ends such [***] during 
such notice period by [***]; provided, that if there is a good faith dispute with respect to the existence of the 
[***] or whether such [***] has ended prior to the expiry of such notice period, and if such matter is disputed 
by GSK in writing [***] of the delivery of the notice thereof, then the dispute resolution procedure set forth in 
[***] may be initiated by either Party to resolve such matter. If either Party so initiates such dispute resolution 
procedure, then [***] (and the corresponding termination of this Agreement), will be tolled until such time as 
the dispute is resolved pursuant to [***]. Notwithstanding the foregoing, the [***] will be extended on a day-
for-day  basis  to  the  extent  that  any  time  period  of  inactivity  in  [***]  is  caused  by  any  one  or  more  of  the 
following:  (a) if Wave is the Manufacturing Lead, [***] in the manner contemplated by this Agreement and 
any subsequent agreement entered into by the Parties relating thereto; (b) a breach of this Agreement by Wave 
with respect to [***] having a material impact on the conduct of the [***]; (c) a clinical hold or other action 
by,  or  delay  in  receiving  or  withholding  of  the  consent  or  approval  of,  a  Regulatory  Authority  that  delays, 
prevents  the  conduct  of,  or  materially  changes  the  conduct  of  [***]  activities  with  respect  to  such  [***], 
including as compared to what had been previously contemplated by either Party; (d) a Force Majeure Event 
that affects the conduct of [***] activities with respect to such [***]; or (e) injunction or other operation of 
law with respect to such [***].

13.5.3.2  For each GSK CP, if GSK does not conduct, or cause to be conducted, any [***] activities with respect to any 
GSK Collaboration Products for a given GSK CP for a period of [***] (the “[***]”), then, Wave will have the 
right to terminate 

‑105‑

  
 
 
this Agreement with respect to such GSK CP with [***] written notice to GSK, unless GSK ends such [***] 
during  such  notice  period  by  conducting,  or  cause  to  be  conducted,  any  [***]  activities  with  respect  to  any 
[***] of any GSK Collaboration Products for such GSK CP; provided, that if there is a good faith dispute with 
respect to the existence of the [***] or whether such [***] has ended prior to the expiry of such notice period, 
and if such matter is disputed by GSK in writing within [***] of the delivery of the notice thereof, then the 
dispute resolution procedure set forth in [***], may be initiated by either Party to resolve such matter. If either 
Party so initiates such dispute resolution procedure, then the [***] (and the corresponding termination of this 
Agreement),  will  be  tolled  until  such  time  as  the  dispute  is  resolved  pursuant  to  [***].  Notwithstanding  the 
foregoing,  the  [***]  period  will  be  extended  on  a  day-for-day  basis  to  the  extent  that  any  time  period  of 
inactivity  in  [***]  is  caused  by  any  one  or  more  of  the  following:    (a)  if  Wave  is  the  Manufacturing  Lead, 
[***] in the manner contemplated by this Agreement and any subsequent agreement entered into by the Parties 
relating  thereto;  (b)  a  breach  of  this  Agreement  by  Wave  with  respect  to  such  GSK  CP  having  a  material
impact on the conduct of the [***]; (c) a clinical hold or other action by, or delay in receiving or withholding 
of  the  consent  or  approval  of,  a  Regulatory  Authority  that  delays,  prevents  the  conduct  of,  or  materially 
changes  the  conduct  of  [***]  activities  with  respect  to  such  [***],  including  as  compared  to  what  had  been 
previously contemplated by either Party; (d) a Force Majeure Event that affects the conduct of [***] activities 
with respect to such [***]; or (e) injunction or other operation of law with respect to such [***].

13.6 Termination for Insolvency.  In the event that either Party (a) files for protection under bankruptcy or insolvency laws; (b) makes an 
assignment  for  the  benefit  of  creditors;  (c)  appoints  or  suffers  appointment  of  a  receiver  or  trustee  over  substantially  all  of  its

debts;  (e)  proposes  or  is  a  party  to  any  dissolution  or  liquidation  of  such  Party;  (f)  files  a  petition  under  any  bankruptcy  or 
insolvency act or has any such petition filed against that is not discharged or dismissed within [***] of the filing thereof; or (g) 
admits  in  writing  its  inability  generally  to  meet  its  obligations  as  they  fall  due  in  the  general  course,  then  the  other  Party  may 
terminate this Agreement in its entirety effective immediately upon notice to such Party.

13.7 Effects of Expiration or Termination; Survival. 

13.7.1 

In addition to the consequences set forth in this Section 13.7 (Effects of Expiration or Termination; Survival)

(Indemnification),  13.7  (Effects  of  Expiration  or  Termination;  Survival),  15  (Dispute  Resolution),  and  16 
(Miscellaneous Provisions); provided that, for clarity, the foregoing will not survive in the event of a termination 
prior to the Effective Date pursuant to Section 14.3 (Outside Date), except as otherwise provided therein.   

13.7.2 

Expiration or termination of this Agreement will not relieve the Parties of any obligation, including any payment 
obligation (in each case, solely with respect to any payment obligations that accrued prior to the effective date of 
such  expiration  or  termination)  or  any  liability  that  accrued  hereunder  prior  to  the  effective  date  of  such 
expiration or termination. In addition, termination of this Agreement will not preclude either Party from pursuing 
all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement 
nor prejudice either Party’s right to obtain performance of any obligation.

13.7.3  Upon expiration of the Royalty Term for a Collaboration Product in a country, the licenses granted from each 
Party to the other Party in Section 7 (Licenses) with respect to such Collaboration Product in such country will 
become fully-paid, irrevocable, and perpetual.

13.7.4  Upon  any  termination  (but  not  expiration)  of  this  Agreement,  the  terms  in  this  Section  13.7.4  will  apply; 
provided that, (a) with respect to any termination of this Agreement with respect to a given Validation Target or 
Collaboration Target but not in its entirety, then the following terms and conditions will apply only with respect 
to each applicable Validation Target or Collaboration Target that is the subject of such termination and (b) the 
terms  in  this  Section  13.7.4  will  only  apply  with  respect  to  a  Wave  Collaboration  Target  in  the  event  of  a

of this Agreement in its entirety). 

13.7.4.1  Within [***] following the receipt of the applicable notice of such termination of this Agreement, the 
Parties would jointly prepare a termination and wind-down plan that will include, at a minimum, a 
plan  for  accomplishing  the  activities  described  in  this  Section  13.7  (Effects  of  Expiration  or

(Reversion  Rights),  all  licenses  granted  under  Section  7  (Licenses)  under  this  Agreement  will 
terminate.    If  this  Agreement  is  terminated  with  respect  to  a  Validation  Target  or  Collaboration 
Target,  then,  except  as  set  forth  in  Section  13.7.4.4  or  13.7.5  (Reversion  Rights),  all  such  licenses 
will terminate only with respect to such Validation Target or Collaboration Target.

13.7.4.3  Except  as  set  forth  in  this  Section  13.7  (Effects  of  Expiration  or  Termination;  Survival),  as  of  the 
effective date of such termination all rights and obligations of the Parties under this Agreement (a) 
will terminate if this Agreement is terminated in its entirety, and (b) with 

‑107‑

  
 
 
respect to applicable Validation Target or Collaboration Target (and the Terminated Products that are 
directed to such Collaboration Target), if this Agreement is terminated with respect to a Validation 
Target or Collaboration Target.

13.7.4.4  Target Lists.  In the event of termination of the Agreement in its entirety during the Research Term 
other than termination by GSK under Section 13.5.1 (Right to Terminate for Material Breach) due to 
a  breach  by  Wave,  Wave  will  have  [***].    For  any  such  [***]  with  the  applicable  terms  and 
conditions in this Agreement set forth [***] after the effective date of termination.

13.7.4.5  Return of Confidential Information.  Each Party will promptly destroy or return to the other Party all 
of  such  other  Party’s  Confidential  Information  that  relates  to  a  Terminated  Target  and  that  was

Party  (or  any  of  its  Affiliates),  except  that  such  Party  will  have  the  right  to  retain  one  (1)  copy  of 
intangible  Confidential  Information  of  such  other  Party  for  legal  and  archival  purposes  under  the 
Party’s record retention policy.  For clarity, the foregoing sentence will not apply in the case of Wave 
for any Confidential Information of GSK that is Reversion Technology.

13.7.4.6  Dissolution of the JSC, JDC, JRC and JPC and Subcommittees.  If this Agreement is terminated in 
its  entirety,  then  the  JSC,  JDC,  JRC  and  JPC  and  all  Subcommittees  will  be  dissolved  as  of  the 
effective date of such termination.

13.7.5  Reversion  Rights.    In  the  event  of  termination  of  the  Agreement  in  its  entirety  other  than  termination  by  GSK  under 
Section 13.5.1 (Right to Terminate for Material Breach) due to a material breach by Wave, in addition to Section 13.7.4, 
(a)  if  this  Agreement  is  terminated  with  respect  to  the  SERPINA1  Target,  then  the  provisions  of  this  Section  13.7.5 
(Reversion Rights) will apply with respect to the then-existing SERPINA1 Compounds and SERPINA1 Products. or (b) if 
this Agreement is terminated with respect to a GSK Collaboration Target for which Wave elects to continue Development 
and  Commercialization  and  the  Parties  reach  agreement  on  terms  pursuant  to  Section  13.7.5.1(a),  the  agreed  terms  will 
apply with respect to the then existing Terminated Products directed to the applicable Terminated Target. 

13.7.5.1  [***].  

(a)  In the event of any termination of this Agreement with respect to a GSK Collaboration Target other than in 
the event of termination by GSK under Section 13.5.1 (Right to Terminate for Material Breach) due to 
breach by Wave, Wave may elect to continue Development and Commercialization of all Terminated 
Products  directed  to  such  GSK  Collaboration  Target  by  providing  written  notice  of  such  election  to 
GSK within [***] after the date such GSK Collaboration Target becomes a Terminated Target.  If Wave 
makes such an election, the Parties shall [***].  

‑108‑

  
 
 
(b)  In  the  event  of  any  termination  of  this  Agreement  with  respect  to  the  SERPINA1  Target,  the  Reversion  
License  set  forth  in  Section  13.7.5.2  will  [***],  and  the  other  provisions  of  this  Section  13.7.5 
(Reversion  Rights)  will  apply  with  respect  to  then  existing  Terminated  Products  directed  to  the 
SERPINA1 Target [***].

(c)  For clarity, in the event of any termination of this Agreement with respect to a Wave Collaboration Target, 
Wave  will  have  no  obligations  to  GSK  with  respect  to  Collaboration  Compounds  or  Collaboration 
Products  directed  to  such  Wave  Collaboration  Target  under  this  Agreement  so  long  as  Wave  or  its 
Affiliates or any sublicensees or assignees of the Collaboration Compounds or Collaboration Products 
directed  to  such  Wave  Collaboration  Target  do  not  develop,  make  or  commercialize  any  such 
Collaboration  Compounds  or  Collaboration  Products  directed  to  such  Wave  Collaboration  Target.    If 
such Collaboration Compounds or Collaboration Products directed to such Wave Collaboration Target 
are  later  developed,  made  or  commercialized  by  or  on  behalf  of,  or  under  license  from,  Wave  or  its 
Affiliates or any sublicensees or assignees, then the royalty obligations, royalty reporting and auditing, 
indemnification  and  compliance  with  laws  provisions  of  this  Agreement  will  still  apply  to  such 
development,  making  or  commercialization  of  any  such  Collaboration  Compounds  or  Collaboration 
Products directed to such Wave Collaboration Target.

13.7.5.2  Reversion  License .  Subject  to  Section  13.7.5.1  [***]  where  the  Terminated  Target  is  the  SERPINA1  Target,
effective upon the effective date of termination of this Agreement or the SERPINA1 Target, GSK will grant

through  multiple  tiers,  under  the  Reversion  Technology,  solely  to  the  extent  necessary  to  Exploit  the  then 
existing  SERPINA1  Compounds  and  SERPINA1  Products  in  the  Field  in  the  Territory  (the  “Reversion 
License”).  

13.7.5.3  Royalties for SERPINA1 Products.  Where the SERPINA1 Target is a Terminated Target, Wave will pay GSK 
royalties based on the aggregate Net Sales (mutatis mutandis) of the then existing SERPINA1 Products sold by

13.7.5.4  Regulatory  Approvals  and  Regulatory  Materials  for  SERPINA1   Products.    Subject  to  Section  13.7.5.1 
[***] where the Terminated Target is the SERPINA1 Target, effective upon the effective date of termination of 
this Agreement or the SERPINA1 Target, GSK will as promptly as practicable, at GSK’s cost, (a) assign to 
Wave  or  Wave’s  designee  possession  and  ownership  of  all  Regulatory  Approvals  and  other  Regulatory 
Documents relating exclusively to the Exploitation of the SERPINA1 Compounds or SERPINA1 Products in 
the  Territory;  provided  that  (i)  [***]  and  (b)  transfer  to  Wave  or  Wave’s  designee  copies  of  all  material 
correspondence  with  Regulatory  Authorities  in  GSK’s  possession  or  Control  related  to  the  SERPINA1 
Compounds or SERPINA1 Products in the Territory, including all non‑clinical and clinical data relating to 

‑109‑

  
 
 
the  SERPINA1  Compounds  or  SERPINA1  Products  and  all  adverse  event  data  related  to  the  SERPINA1 
Compounds or SERPINA1 Products, in each case, in the Territory and in GSK’s possession and Control.    

13.7.5.5  Continuation of Supply for SERPINA1 Products.  Subject to Section 13.7.5.1 [***], where the Terminated 
Target  is  the  SERPINA1  Target,  effective  upon  the  effective  date  of  termination  of  this  Agreement  or  the 
SERPINA1  Target,  if  GSK  or  its  Related  Parties  are  Manufacturing  finished  product  with  respect  to 
SERPINA1 Compounds or SERPINA1 Products on the effective date of termination of this Agreement, then 
at  Wave’s  request,  GSK  or  its  Related  Parties  will  negotiate  in  good  faith  to  enter  into  a  commercially 
reasonable  supply  agreement  pursuant  to  which  GSK  or  such  Related  Party  would  supply  such  finished 
product to Wave under customary supply terms (including reasonable commercial supply price markup), until 
the earlier of (a) such time as all Regulatory Approvals related to the SERPINA1 Compounds or SERPINA1 
Products  have  been  assigned  to  Wave  or  its  designee,  Wave  has  obtained  all  necessary  manufacturing 
approvals, and Wave has procured or developed its own source of such finished product supply, or (b) [***]

14.  EFFECTIVENESS

14.1 Effective  Date .    Notwithstanding  anything  to  the  contrary  set  forth  herein,  except  for  the  Parties’  obligations  under  Section  10 
(Confidentiality)  and  this  Section  14  (Effectiveness),  which  will  be  effective  as  of  the  Execution  Date,  this  Agreement  will  not
become effective until the first Business Day after the later to occur of: (a) the HSR Conditions are met and (b) the Closing of the 
Share  Purchase  Agreement  (where  “Closing”  will  have  the  meaning  set  forth  in  the  Share  Purchase  Agreement)  (such  date  the 
“Effective  Date”).    Notwithstanding  the  foregoing  clause  (a),  the  Effective  Date  will  not  occur  (i)  if  a  Party  exercises  its 
termination right pursuant to Section 14.3 (Outside Date) and (ii) for so long as there is in force any Applicable Law or order from a 
Governmental  Authority  enjoining  or  prohibiting  the  consummation  of  the  transactions  contemplated  by  this  Agreement,  or 
imposing any conditions in connection with such effectiveness. 

14.2 Antitrust Filings.  If any applicable waiting periods and approvals are required under Antitrust Laws with respect to the transactions 
contemplated under this Agreement, then each Party (or its Affiliate) will file the appropriate notices under the HSR Act or similar 
notices or filings under 

‑110‑

  
 
 
Applicable  Laws  in  any  other  jurisdiction  (“Antitrust  Filings”)  within  [***]  after  the  Execution  Date.  The  Parties  shall  use 
reasonable best efforts to seek to obtain the expiration or early termination of the applicable waiting period under the HSR Act, and 
will keep each other apprised of the status of any communications with, and any inquiries or requests for additional information 
from,  the  United  States’  Federal  Trade  Commission  (“FTC”),  the  Antitrust  Division  of  the  United  States  Department  of  Justice 
(“DOJ”)  and  any  other  Governmental  Authority  with  which  an  Antitrust  Filing  is  made  and  will  comply  promptly  with  any 
reasonable FTC, DOJ or other Governmental Authority inquiry or request of this nature; provided that neither Party will be required 
to  consent  to  the  divestiture  or  other  disposition  of  any  of  its  assets  (or  the  assets  of  its  Affiliates)  or  to  consent  to  any  other 
structural or conduct remedy, and each Party and its Affiliates will have no obligation to contest, administratively or in court, any 
ruling, order or other action of the FTC, DOJ, other Governmental Authority or any Third Party with respect to the transactions 
contemplated  by  this  Agreement.  GSK  will  (i)  control  the  strategy  for  obtaining  any  consents,  approvals  of,  or  registrations,
declarations  or  filings  from  any  Governmental  Authority  in  connection  with  the  transaction  and  (ii)  coordinate  the  overall 
development of the positions to be taken and the regulatory actions to be requested in any filing or submission with a Governmental 
Authority in connection with the transactions contemplated hereby.  [***]. Each of the Parties hereto will furnish to the other such 
necessary information and reasonable assistance as the other may request in connection with the preparation of any required filings 
or submissions and will cooperate in responding to any inquiry from the FTC or DOJ and to any requests for additional information 
at the earliest practicable date, including promptly informing the other Party of such inquiry, consulting in advance before making 
any presentations or submissions to the FTC or DOJ, and supplying each other with copies of all material correspondence, filings or 
communications between either party and either the FTC or DOJ with respect to this Agreement. Such information can be shared on 
an outside counsel basis or subject to other restrictions to the extent deemed necessary or advisable by counsel for the disclosing 
Party.  To  the  extent  practicable  and  as  permitted  by  the  FTC  or  DOJ,  each  Party  hereto  shall  permit  representatives  of  the  other 
Party to participate in material substantive meetings (whether by telephone or in person) with the FTC or DOJ. Neither Party shall 
commit to or agree with the FTC or DOJ to withdraw its filing and refile under the HSR Act without the prior written consent of the 
other (such consent not to be unreasonably withheld, conditioned or delayed).

14.3 Outside  Date .    If,  any  applicable  waiting  periods  and  approvals  are  required  under  Antitrust  Laws  with  respect  to  the  transactions 
contemplated under this Agreement, this Agreement will terminate, at the election of either Party, immediately upon written notice 
to the other Party, in the event that: (a) the FTC, the DOJ or an equivalent other Governmental Authority in any jurisdiction outside 
the U.S., seeks a permanent injunction under applicable antitrust and non-competition Applicable Laws against the parties to enjoin 
the transactions contemplated by this Agreement; or (b) the Antitrust Clearance Date has not occurred on or prior to [***] after the 
effective date of any Antitrust Filing (or such later date as may be mutually agreed by the Parties).  In the event of such termination, 
without any further action on the part of either Party, this Agreement will be of no further force and effect and no Party will have 
any further obligations under this Agreement, except for the Parties’ obligations under Section 10 (Confidentiality) which survive.

15.  DISPUTE RESOLUTION

15.1 Disputes.  Except as otherwise expressly set forth in this Agreement, including Section 2.8 (Resolution of Committee Disputes), any

the resolution of disputes arising under this Agreement in an expedient manner by 

‑111‑

  
 
 
mutual  cooperation  and  without  resort  to  arbitration  or  litigation.    Accordingly,  it  is  the  Parties’  expectation  that  most  Disputes 
related  to  the  strategy  or  operation  of  the  Collaboration  Programs  will  first  be  escalated  to  the  JSC  and  will  be  resolved  in 
accordance with Section 2.8 (Resolution of Committee Disputes).

15.3 Mediation.  Subject to Section 15.6 (Injunctive Relief) and Section 15.7 (Intellectual Property Disputes), for (a) [***], the Parties agree

the mediator will, upon request by either Party, be appointed by CPR pursuant to CPR Mediation Procedure.  The cost of mediator 
will be borne equally by the Parties.  Any [***] referred to mediation under this Section 15.3 (Mediation) that is not resolved within 
[***] (or within such other time period as may be agreed to by Parties in writing) after appointment of the mediator will be resolved 
[***].

the subject matter of such dispute. 

15.4.3 

The governing law in Section 16.9 (Governing Law) will govern such proceedings.  The place of arbitration will be New

15.4.4 

The arbitrator will use their best efforts to rule on the dispute [***] after appointment of the arbitrator.  The arbitrator will

gross negligence or manifest error.  All rulings of the arbitrator will be in writing and will be delivered to the Parties as 
soon  as  is  reasonably  possible.    Nothing  contained  herein  will  be  construed  to  permit  the  arbitrator  to  award  punitive, 
exemplary or any similar damages.  Any arbitration award may be entered in and enforced by a court in accordance with 
Section 15.4.5, Section 15.6 (Injunctive Relief) and Section 15.7 (Intellectual Property Disputes), as applicable.

15.4.5  Any award to be paid by one Party to the other Party as determined by the arbitrator as set forth above under Section

enforcing  the  award  will,  to  the  maximum  extent  permitted  by  Applicable  Law,  be  charged  against  the  Party  resisting 
enforcement.  Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Section 15.4 
(Arbitration) and that judgment may be entered upon the final award in a 

‑112‑

  
 
 
court of competent jurisdiction and that other courts may award full faith and credit to such judgment in order to enforce 
such award.

15.4.6 

The arbitrator may award to the prevailing Party, if any, as determined by the arbitrator as set forth above under Section 
15.4.4, the prevailing Party’s cost, fees and expenses incurred in connection with such arbitration.

15.5 [***]. Notwithstanding the foregoing, any [***] will be resolved by [***] as follows:

15.5.1 

The Parties will discuss in good faith and agree [***] shall be [***] for the [***].

15.5.2 

Each  Party  will  prepare  and  submit  a  written  summary  of  such  Party’s  position  with  respect  to  such  disputed 
matter and any relevant evidence in support thereof to the [***] of selection of the [***].  Such [***] will be

The decision by the [***] will be final and binding on the Parties and not subject to appeal of any kind, except in 
the case of fraud, willful misconduct or gross negligence or manifest error. 

15.6 Injunctive Relief. Nothing in this Agreement will be construed as precluding a Party from bringing an action for injunctive relief or 
other  equitable  relief,  including  prior  to  the  initiation  or  completion  of  the  dispute  resolution  mechanisms  contemplated  by  this 
Agreement.  

15.7 Intellectual Property Disputes.  Notwithstanding any provision to the contrary set forth in this Agreement, if a Dispute arises under 
this  Agreement  with  respect  to  the  validity,  scope,  enforceability  or  ownership  of  any  Patent,  Know-How  or  other  intellectual 
property  rights,  and  such  Dispute  is  not  resolved  through  [***]then  such  Dispute  will  be  submitted  to  a  court  of  competent 
jurisdiction in the jurisdiction in which such Patent, Know-How or other intellectual property right was granted or arose.

15.8 Confidentiality.  All dispute resolution proceedings undertaken by the Parties pursuant to this Section 15 (Dispute Resolution) will be 
confidential and the Parties’ will take appropriate measures to safeguard each Party’s Confidential Information.  Except as required 
by  Applicable  Law,  no  Party  will  make  (or  instruct  any  Third  Party,  including  any  mediator  or  arbitrator,  to  make)  any  public 
announcement  with  respect  to  the  dispute  resolution  proceedings  or  any  final  resolution  of  any  Dispute  hereunder,  in  each  case, 
without prior written consent of the other Party.  The existence of any Dispute under this Section 15 (Dispute Resolution), and any 
final resolution, decision or award reached or granted pursuant to this Section 15 (Dispute Resolution), will be kept in confidence 
by the Parties (in each case, except to the extent disclosure is required under Applicable Law or to the extent necessary to enforce 
the  rights  arising  out  of  the  award)  and  any  mediator  or  arbitrator,  as  applicable,  except  as  required  in  connection  with  the 
enforcement of such final resolution, decision or award or as otherwise required by Applicable Law.

‑113‑

  
 
 
15.9 Tolling.  The Parties agree that all applicable statutes of limitation and time‑based defenses (such as estoppel and laches), as well as all 
time  periods  in  which  a  Party  must  exercise  rights  or  perform  obligations  hereunder,  will  be  tolled  once  the  dispute  resolution 
procedures set forth in this Section 15 (Dispute Resolution) have been initiated and for so long as they are pending, and the Parties 
will cooperate in taking all actions reasonably necessary to achieve such a result.  In addition, during the pendency of any Dispute 
under this Agreement initiated before the end of any applicable cure period, including under Section 13.5 (Termination for Cause), 
(a)  this  Agreement  will  remain  in  full  force  and  effect,  (b)  the  provisions  of  this  Agreement  relating  to  termination  for  material 
breach with respect to such Dispute will not be effective, (c) the time periods for cure under Section 13.5 (Termination for Cause) as 
to any termination notice given prior to the initiation of arbitration will be tolled, (d) any time periods to exercise rights or perform

matter of the arbitration, in each case ((a) – (e)), until the arbitral tribunal has confirmed the material breach and the existence of the 
facts claimed by a Party to be the basis for the asserted material breach; provided that if such breach can be cured by (i) the payment 
of  money,  then  the  defaulting  Party  will  have  an  additional  [***]  after  its  receipt  of  the  arbitral  tribunal’s  decision  to  pay  such 
amount,  or  (ii)  the  taking  of  specific  remedial  actions,  the  defaulting  Party  will  have  a  reasonably  necessary  period  to  diligently 
undertake  and  complete  such  remedial  actions  within  such  reasonably  necessary  period  or  any  specific  timeframe  established  by 
such arbitral tribunal’s decision before any such notice of termination can be issued.  Further, with respect to any time periods that 
have run during the pendency of the Dispute, the applicable Party will have a reasonable period of time or any specific timeframe 
established by such arbitral tribunal’s decision to exercise any rights or perform any obligations affected by the running of such time 
periods.

16.  MISCELLANEOUS PROVISIONS

16.1 Relationship of the Parties. Nothing in this Agreement is intended or will be deemed, for financial, Tax, legal or other purposes, to 

constitute a partnership, agency, joint venture or employer-employee relationship between the Parties.

16.2 Assignment.  Except as expressly provided herein, neither this Agreement nor any right or obligation hereunder will be assignable or
transferable, whether voluntarily or by operation of law, without the prior written consent of the other Party (not to be unreasonably
withheld or delayed).

16.2.1 

Each Party may assign or transfer this Agreement or any of its rights and obligations hereunder to any Affiliate, or to any 
Third Party that acquires all, or substantially all, of such Party’s assets or business, relating to all, or substantially all, of 
the  business  of  the  assigning  Party  to  which  the  subject  matter  of  this  Agreement  relates  (whether  by  sale  of  assets  or 
stock, merger, consolidation, reorganization or otherwise), without the consent of the other Party.  Each Party may assign 
its rights and obligations under this Agreement with respect to the SERPINA1 Program to any Third Party that acquires 
all, or substantially all, of such Party’s assets or business, relating to the SERPINA1 Program, without the consent of the 
other Party.  GSK may assign its rights and obligations under this Agreement with respect to any GSK CP to any Third 
Party that acquires all, or substantially all, of GSK’s assets or business, relating to such GSK CP, without the consent of 
Wave.  Wave may assign its rights and obligations under this Agreement with respect to a given Wave CP to any Third 
Party that acquires all, or substantially all, of Wave’s assets or business, relating to such Wave CP, without the consent of 
GSK; [***]. An assignment to an Affiliate will terminate, and all rights so assigned will revert to the assigning Party, if 
and when such Affiliate ceases to be an Affiliate of the assigning Party.  Each assigning Party will give written notice to 
the other Party promptly following any such assignment or transfer.

‑114‑

  
 
 
16.2.2  No  assignment  under  this  Section  16.2  (Assignment)  will  relieve  the  assigning  Party  of  any  of  its  responsibilities  or 
obligations  hereunder  and,  as  a  condition  of  such  assignment,  the  assignee  will  agree  in  writing  to  be  bound  by  all

the Parties.

16.2.3  Any assignment or other transfer not in accordance with this Section 16.2 (Assignment) will be null and void.

or  licenses  hereunder  exercised,  by  any  of  its  Affiliates  and  the  performance  of  such  obligations  by  any  such  Affiliate  will  be 
deemed to be performance by such Party; provided, however, that such Party will be responsible for ensuring the performance of its 
obligations  under  this  Agreement  and  that  any  failure  of  any  Affiliate  performing  obligations  of  such  Party  hereunder  will  be 
deemed to be a failure by such Party to perform such obligations. For clarity, the foregoing means that each Party may designate or 
subcontract to an Affiliate to perform its obligations hereunder or to be the recipient of the other Party’s performance obligations 
hereunder.

failure  or  delay  in  the  performance  of  any  of  its  obligations  under  this  Agreement  for  the  time  and  to  the  extent  such 
failure  or  delay  is  caused  by  or  results  from  any  condition,  the  occurrence  and  continuation  of  which  is  beyond  the 
reasonable  control  of  the  affected  Party,  which  may  include  (a)  fire,  floods,  earthquakes  or  other  acts  of  nature;  (b) 
epidemics,  pandemics,  the  spread  of  infectious  diseases,  quarantines  or  disease  outbreaks  (including,  to  the  extent 
permitted by Section 16.6.2, COVID-19 or other ongoing events); (c) sanctions and embargoes; (d) war or acts of war, 
terrorism,  sabotage,  nuclear  threat  or  activity,  insurrections,  riots  or  civil  unrest;  (e)  strikes,  lockouts  or  other  labor

judicial orders or decrees; (g) delay or impossibility to obtain materials, intermediates, components, active pharmaceutical 
ingredient,  utilities,  equipment,  supplies,  fuel  or  other  required  materials,  or  failure  or  delay  of  transportation  (in  each 
case, due to reasons other than the affected Party’s negligence, willful misconduct or any other cause within the reasonable 
control of the affected Party); (h) failure of plant or machinery (provided that such failure could not have been prevented 
by  the  exercise  of  skill,  diligence  or  prudence  that  would  be  reasonably  and  ordinarily  expected  from  a  skilled  and 
experienced person engaged in the same type of undertaking under the same or similar circumstances or restrictions); or 
(i)  any  other  reason  or  circumstance  that  is  beyond  the  reasonable  control  of  the  affected  Party  (“Force  Majeure 
Events”).  The Party affected by a Force Majeure Event will (i) provide the other Party with full particulars thereof as 
soon 

‑115‑

  
 
 
as it becomes aware of the same (including its best estimate of the likely extent and duration of the interference with its 
activities)  and  (ii)  use  Commercially  Reasonable  Efforts  to  overcome  the  difficulties  created  thereby  and  to  resume 
performance of its obligations hereunder as soon as practicable.

16.6.2 

For  clarity,  GSK  and  Wave  acknowledge  and  agree  that  either  Party’s  ability  to  perform  its  obligations  under  this 
Agreement  after  the  Execution  Date  may  be  affected  by  certain  known  ongoing  Force  Majeure  Events,  including,  for 
example, COVID-19 or other pandemics and war in Europe.  As such, both Parties understand and acknowledge and agree 
that any change in circumstances related to such ongoing events by a Governmental Authority or Regulatory Authority 
(e.g.,  another  mandatory  shelter  in  place  or  stay  at  home  order  or  changes  to  essential  business  rules)  may  constitute  a 
Force Majeure Event even if the change in circumstances itself is foreseeable.  If a Party is prevented from performing any 
of  its  obligations  under  this  Agreement  due  to  a  change  in  circumstances  as  a  result  of  such  ongoing  events  after  the 
Execution Date, such non-performing Party will provide written notice to the other Party of such change in circumstances, 
and  from  and  after  such  notice,  will  not  be  liable  for  breach  of  this  Agreement  with  respect  to  such  non-performance 
during the period of such Force Majeure Event.  Without limiting the foregoing, through the JSC, the Parties will agree on 
extensions  to  timeframes  set  forth  in  this  Agreement  to  account  for  delays  in  carrying  out  activities  and  obligations 
hereunder to the extent such delays are a result of disruptions to business caused by the aforementioned ongoing events or 
related laws or regulations.

16.7 Entire Agreement; Amendments. This Agreement, and the Schedules and Exhibits hereto, and the Equity Agreements will constitute 
and contain the entire understanding and agreement of the Parties respecting the subject matter hereof and cancel and supersede any 
and all prior negotiations, correspondence, understandings and agreements between the Parties, whether oral or written, regarding 
such  subject  matter,  including  the  Existing  Confidentiality  Agreement.    Except  as  specified  herein,  no  waiver,  modification  or 
amendment of any provision of this Agreement will be valid or effective unless made in writing referencing this Agreement and 
signed by a duly authorized officer of each Party.

16.8 Headings. The headings to this Agreement are for convenience only and are to be of no force or effect in construing or interpreting any 

of the provisions of this Agreement.

16.9 Governing Law. This Agreement, and all claims or causes of action (whether in contract, tort or statute) that may be based upon, arise 
out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement (including any claim or cause of 
action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an 
inducement to enter into this Agreement), will be governed by and interpreted in accordance with the internal Applicable Laws of 
the State of New York, including its statutes of limitations but excluding application of any conflict of laws principles that would 
require application of the Applicable Law of a jurisdiction outside of the State of New York.  The United Nations Convention on 
Contracts for the International Sale of Goods will not apply to this Agreement.

under Applicable Law, but if any provision of this Agreement is held to be prohibited by or invalid under Applicable Law, such

Agreement. The

economic effect is most consistent with the invalid or unenforceable provision.

Wave Life Sciences and GSK Announce Collaboraon to Drive Discovery and Development of Oligonucleode Therapeucs Focusing 
on Novel Genec Targets 

Wave receives upfront payment of $170 million in cash and equity, also eligible to receive milestone payments and royales  

Collaboraon brings together Wave’s PRISMTM oligonucleode plaorm and GSK’s experse in genecs and genomics

GSK to advance up to eight preclinical programs

Addionally, GSK receives exclusive global license to Wave’s preclinical, potenal first-in-class RNA eding program, WVE-006, to treat 
alpha-1 antrypsin deficiency, a disease that impacts the lungs and liver

Wave to advance up to three preclinical programs for targets informed by GSK’s novel insights 

Wave to host investor conference call and webcast at 8:30 a.m. ET today

CAMBRIDGE, Mass., and LONDON, December 13, 2022 – Wave Life Sciences Ltd. (Nasdaq: WVE), a clinical-stage genec medicines 
company commied to delivering life-changing treatments for people baling devastang diseases, and GSK plc (LSE/NYSE: GSK) today 
announced a strategic collaboraon to advance oligonucleode therapeucs, including Wave’s preclinical RNA eding program targeng 
alpha-1 antrypsin deficiency (AATD), WVE-006. The discovery collaboraon has an inial four-year research term. It combines GSK’s 
unique insights from human genecs, as well as its global development and commercial capabilies, with Wave’s proprietary discovery 
and drug development plaorm, PRISMTM.

Oligonucleodes are short strands of DNA or RNA that can reduce, restore, or modulate RNA through several different mechanisms. The 
unique capability of oligonucleodes to address a wide range of genomic targets in mulple therapeuc areas is enabling new 
opportunies to treat a range of human diseases, including diseases where no medicines currently exist or that have historically been 
difficult to treat with small molecules or biologics. 

Wave’s PRISM plaorm is the only oligonucleode plaorm offering three RNA-targeng modalies (eding, splicing, and silencing, 
including siRNA and ansense). Importantly, these modalies incorporate novel chemistry, including PN backbone chemistry and control 
of stereochemistry, to opmize the pharmacological properes of therapeuc oligonucleodes. 

 
 
 
 
 
 
 
 
 
  
 
 
 
 
The collaboraon includes two main components. The first is a discovery collaboraon which enables GSK to advance up to eight 
programs and Wave to advance up to three programs, leveraging Wave’s PRISM plaorm and GSK’s experse in genecs and genomics. 
In addion to these programs, GSK receives the exclusive global license for Wave’s preclinical program for AATD called WVE-006, which 
uses Wave’s proprietary “AIMer” technology (A-to-I(G) RNA eding). AATD is an inherited genec disease that affects both the lungs and 
liver with limited treatment opons. Wave’s WVE-006 is a first-in-class RNA eding therapeuc that is designed to address both liver and 
lung manifestaons of the disease.

Paul Bolno, MD, MBA, President and Chief Execuve Officer, Wave Life Sciences, said: “For the past decade, Wave has been building a 
unique oligonucleode plaorm that combines novel chemistry with the means to opmally address disease biology through mulple 
therapeuc modalies. In 2022, we started to deliver on the promise of our plaorm with the first data showing translaon in the clinic 
for our next-generaon stereopure PN-chemistry containing candidates. Now with our GSK collaboraon, we are excited to leverage 
their experse in genecs to connue building a differenated oligonucleode pipeline, with a focus on our best-in-class RNA eding 
and upregulaon capability. Addionally, GSK is the ideal partner for our WVE-006 program, due to their longstanding history and global 
reach in respiratory diseases. The collaboraon meaningfully extends our cash runway into 2025 and offers the potenal for significant 
future milestones, providing new resources to deliver life-changing medicines to paents.”

Tony Wood, President and Chief Scienfic Officer, GSK, said: “Oligonucleode therapeucs are becoming a mainstream modality, and 
this collaboraon will enable us to use our leading posion in human genecs and genomics to advance novel oligonucleode therapies. 
Pairing GSK's genec experse with the best-in-class PRISMTM plaorm enables us to accelerate drug discovery for newly-idenfied 
targets, by matching target to modality. The addion of WVE-006 complements more advanced, clinical-phase oligonucleodes in our 
pipeline, including bepirovirsen for chronic hepas B and GSK4532990 for non-alcoholic steatohepas (NASH).”

Bepirovirsen, an invesgaonal ansense oligonucleode for the potenal treatment of chronic hepas B infecon, is now entering 
Phase III trials, and GSK4532990, a siRNA oligonucleode, is progressing to Phase II for NASH. WVE-006 brings a third oligonucleode 
into GSK’s porolio that has the potenal to be a first-in-class AATD treatment for both lung and liver disease and is a well-understood 
genec target, contribung to GSK’s pipeline that is now more than 70% genecally validated.

The companies expect to pursue targets across mulple disease areas, given preclinical data indicang Wave oligonucleodes can 
distribute to various ssues and cells without complex delivery vehicles.

Terms of the Collaboraon
Under the terms of the agreement, Wave will receive an upfront payment of $170 million, which includes a cash payment of $120 
million and a $50 million equity investment. 

For the WVE-006 program, Wave is eligible to receive up to $225 million in development and launch milestone payments and up to $300 
million in sales-related milestone payments, as well as ered sales royales. Development and commercializaon responsibilies will 
transfer to GSK aer Wave completes the first-in-paent study.

 
 
 
 
 
 
 
 
 
For each of GSK’s eight collaboraon programs, Wave will be eligible to receive up to $130-$175 million in development and launch 
milestones and $200 million in sales-related milestones, along with ered sales royales. Wave will lead all preclinical research for GSK 
and Wave programs up to invesgaonal new drug (IND) enabling studies. GSK collaboraon programs will transfer to GSK for IND-
enabling studies, clinical development, and commercializaon. The collaboraon includes an opon to extend the research term for up 
to three addional years, expanding the number of programs available to both pares. 

The equity investment and collaboraon agreement will complete at the same me and are condional upon customary condions 
including regulatory review by the appropriate regulatory agencies under the Hart-Sco-Rodino Act.

Investor Conference Call and Webcast
Wave management will host an investor conference call today at 8:30 a.m. ET to discuss the strategic collaboraon announcement. The 
webcast of the conference call and corresponding slide presentaon may be accessed by vising “Events” on the investor relaons 
secon of the Wave Life Sciences corporate website: ir.wavelifesciences.com/events-and-presentaons. 

Analysts planning to parcipate during the Q&A poron of the live call can join the conference call at the audio conferencing link 
available here. Once registered, parcipants will receive the dial-in informaon. Following the live event, an archived version of the 
webcast will be available on the Wave Life Sciences website.

About Oligonucleodes
Oligonucleode mechanisms that can reduce, increase or modify RNA include silencing (oligonucleodes that promote degradaon of 
the target RNA, including ansense and siRNA); splicing (oligonucleodes that involve binding to the target RNA and modulang its 
funcon by promong exon skipping); and ADAR-mediated RNA eding (oligonucleodes that edit adenosines in target RNAs to correct 
RNA or modulate protein funcon or producon). GSK's investments in genecs have revealed that a significant number of genec 
associaons point to proteins where modulaon of RNA funcon and/or expression would likely be the most effecve mechanism for 
therapeuc intervenon versus more tradional small molecules and biologic-based therapeucs. Oligonucleode therapeucs 
represent a modality that addresses this gap by regulang target expression rather than funcon.

About AIMers
Wave’s AIMers are designed to correct mutaons in an RNA transcript, thereby avoiding permanent changes to the genome that occur 
with DNA-targeng approaches. Rather than using an exogenous eding enzyme, AIMers recruit normal proteins that exist in the body, 
called ADAR enzymes, which naturally edit certain adenine (A) bases to inosine (I). Because I is read as G (guanine) by the cellular 
translaonal machinery, sequence-directed eding with ADAR has the potenal to revert transcripts with single G-to-A point mutaons 
that cause genec diseases. This approach redirects a natural system for therapeuc purposes, enables simplified delivery without viral 
parcles or liposomes, and avoids the risk of irreversible off-target effects of DNA-targeng approaches. AIMers are short in length, fully 
chemically modified, and use novel chemistry, including proprietary PN backbone modificaons and chiral control, that make them 
disnct from other ADAR-mediated eding approaches.

About Alpha-1 Antrypsin Deficiency

 
 
 
 
 
 
 
 
Alpha-1 antrypsin deficiency (AATD) is an inherited genec disorder that is commonly caused by a G-to-A point mutaon (“Z allele”) in 
the SERPINA1 gene. This mutaon leads to lung disease due to lack of wild-type alpha-1 antrypsin (M-AAT) funcon in lungs, and it 
leads to liver disease due to aggregaon of misfolded Z-AAT protein in hepatocytes. There are approximately 200,000 paents in the 
United States and Europe who have Z mutaons on both alleles, known as the PiZZ genotype. Augmentaon therapy via delivery of AAT 
protein is the only treatment opon for AATD lung disease and requires weekly intravenous infusions. There are no treatments for AATD 
liver disease, other than liver transplantaon.

About WVE-006
WVE-006 is a PN chemistry-modified GalNAc-conjugated invesgaonal development candidate for the treatment of alpha-1 antrypsin 
deficiency (AATD), designed to correct the mutant SERPINA1 Z allele transcript to address both liver and lung manifestaons of disease. 
WVE-006 is a potenal first-in-class RNA eding candidate (AIMer) and the most advanced program currently in development using an 
oligonucleode to harness an endogenous enzyme for eding. Wave expects to submit clinical trial applicaons for WVE-006 in 2023.

About Wave Life Sciences
Wave Life Sciences (Nasdaq: WVE) is a clinical-stage genec medicines company commied to delivering life-changing treatments for 
people baling devastang diseases. Wave aspires to develop best-in-class medicines across mulple therapeuc modalies using 
PRISM, the company’s proprietary discovery and drug development plaorm that enables the precise design, opmizaon, and 
producon of stereopure oligonucleodes. Driven by a resolute sense of urgency, the Wave team is targeng a broad range of 
genecally defined diseases so that paents and families may realize a brighter future. To find out more, please visit

About Oligonucleotides
Oligonucleotide mechanisms that can reduce, increase or modify RNA include silencing (oligonucleotides that promote degradation of the 
target RNA, including antisense and siRNA); splicing (oligonucleotides that involve binding to the target RNA and modulating its function by 
promoting exon skipping); and ADAR-mediated RNA editing (oligonucleotides that edit adenosines in target RNAs to correct RNA or 
modulate protein function or production). GSK's investments in genetics have revealed that a significant number of genetic associations point 
to proteins where modulation of RNA function and/or expression would likely be the most effective mechanism for therapeutic intervention 
versus more traditional small molecules and biologic-based therapeutics. Oligonucleotide therapeutics represent a modality that addresses 
this gap by regulating target expression rather than function. 

About AIMers
Wave’s AIMers are designed to correct mutations in an RNA transcript, thereby avoiding permanent changes to the genome that occur with 
DNA-targeting approaches. Rather than using an exogenous editing enzyme, AIMers recruit normal proteins that exist in the body, called

About Alpha-1 Antitrypsin Deficiency
Alpha-1 antitrypsin deficiency (AATD) is an inherited genetic disorder that is commonly caused by a G-to-A point mutation (“Z allele”) in the 
SERPINA1 gene. This mutation leads to lung disease due to lack of wild-type alpha-1 antitrypsin (M-AAT) function in lungs, and it leads to 
liver disease due to aggregation of misfolded Z-AAT protein in hepatocytes. There are approximately 200,000 patients in the United States 
and Europe who have Z mutations on both alleles, known as the PiZZ genotype. Augmentation therapy via delivery of AAT protein is the only 
treatment option for AATD lung disease and requires weekly intravenous infusions. There are no treatments for AATD liver disease, other 
than liver transplantation.

About WVE-006
WVE-006 is a PN-chemistry modified GalNAc-conjugated investigational development candidate for the treatment of alpha-1 antitrypsin 
deficiency (AATD), designed to correct the mutant SERPINA1 Z allele transcript to address both liver and lung manifestations of disease. 
WVE-006 is a potential first-in-class RNA editing candidate (AIMer) and the most advanced program currently in development using an

(b)  The Company is qualified to transact business as a foreign entity and is in good standing in each 
jurisdiction in which the type of properties owned, leased or operated by the Company or the nature of the business conducted by

likely to have a Material Adverse Effect. 

4.2  Capitalization and Voting Rights.

(a)  As of September 30, 2022, the share capital, which has been authorized for issuance by the Board 
of Directors and shareholders of the Company, consists of (1) 104,218,716 Ordinary Shares, of which (i) 86,841,523 Ordinary

assessable.    None  of  the  outstanding  share  capital  of  the  Company  was  issued  in  violation  of  the  preemptive  or  other  similar 
rights of any shareholder of the Company.  There are no authorized or outstanding options, warrants, preemptive rights, rights of 
first refusal or other rights to purchase, or equity or debt securities convertible into or exchangeable or exercisable for, any share 
capital  of  the  Company  or  any  of  its  subsidiaries  other  than  those  described  or  reflected  above  or  in  the  Company  SEC 
Documents, or pursuant to reservations, agreements or employee benefit plans or the exercise of convertible securities or options, 
in each case described or reflected in the Company SEC Documents.  

(b)  All of the Ordinary Shares are entitled to one (1) vote per share. 

6

 
 
 
 
(c)  Except as described or referred to in Section 4.2(a) above or the Company SEC Documents or as 
provided in the Investor Agreement, as of the date hereof, there are not: (i) any outstanding equity securities, options, warrants, 
rights (including conversion or preemptive or registration rights) or other agreements pursuant to which the Company is or may 
become obligated to issue, sell or repurchase any of its share capital or any other securities of the Company or (ii) except as set 
forth in the Investor Agreement, any restrictions on the transfer of share capital of the Company other than pursuant to state and 
federal securities Laws.

(d)  Except as provided in the Investor Agreement or the Organizational Documents, the Company is 
not a party to or subject to any agreement or understanding relating to the voting of share capital of the Company or the giving of 
written consents by a shareholder or director of the Company.

4.3  Subsidiaries.    The Company has  disclosed  all  of  its  “subsidiaries”  (for  purposes  of  this  Agreement, as 
defined in Rule 405  under  the  Securities  Act)  required  to  be  disclosed  pursuant to Item 601(b)(21) of Regulation S-K in an 
exhibit to its Annual Report on Form 10-K.   Each of the Company’s subsidiaries has been duly incorporated or organized, as 
the case may be, and is validly existing as a corporation or company in good standing under the Laws of the jurisdiction of its 
incorporation or organization and has the power and authority (corporate or other) to own, lease and operate its properties and 
to conduct its businesses as presently conducted.  Each of the Company’s subsidiaries is duly qualified as a foreign corporation
or company to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by 
reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or to be in good 
standing would not reasonably be expected to have a Material Adverse Effect.  All of the issued and outstanding share capital 
or other equity or ownership interests of each of the Company’s subsidiaries have been duly authorized and validly issued, are 
fully paid and non-assessable and are owned by the Company, directly or through subsidiaries, free and clear of any security 
interest, mortgage, pledge, lien, encumbrance or adverse claim.  The Company does not own or control, directly or indirectly, 
any corporation, association or other entity other than the subsidiaries listed in Company SEC Documents.

4.4  Authorization.

(a)  All requisite corporate action on the part of the Company and its subsidiaries, and their respective 
directors  and  shareholders  required  by  applicable  Law  for  the  authorization,  execution  and  delivery  by  the  Company  and  its 
subsidiaries of the Transaction Agreements and the performance of all obligations of the Company and its subsidiaries hereunder 
and thereunder, including the authorization, allotment, issuance and delivery of the Shares, has been taken.

(b)  This Agreement and the Collaboration Agreement have been, and upon the execution and delivery 
of the Investor Agreement by the Company at the Closing, the Investor Agreement will be, duly executed and delivered by the 
Company  or  its  subsidiaries  (as  applicable),  and  upon  the  due  execution  and  delivery  of  this  Agreement  by  the  Investor,  this 
Agreement and the Collaboration Agreement will constitute, and upon the due execution and delivery of the Investor Agreement 
by the Investor, the Investor Agreement will constitute, valid and legally 

7

 
 
 
 
binding obligations of the Company and its subsidiaries (as applicable), enforceable against such entities in accordance with their 
respective  terms  (except  as  such  enforceability  may  be  limited  by  (i)  applicable  bankruptcy,  insolvency,  reorganization, 
moratorium or other Laws of general application relating to or affecting enforcement of creditors’ rights and (ii) rules of Law 
governing specific performance, injunctive relief or other equitable remedies and limitations of public policy).

except, in the case of subsections (b) and (c), as would not have or be reasonably likely to have a Material Adverse Effect.  To 
the  knowledge  of  the  Company,  there  exists  no  condition,  event  or  act  which  after  notice,  lapse  of  time,  or  both,  would 
constitute a default or violation by the Company under any of the foregoing, except, in the case of subsections (b) and (c), as 
would not have or be reasonably likely to have a Material Adverse Effect.

4.6  No Conflicts.  The execution, delivery and performance of the Transaction Agreements, and compliance 
with the provisions hereof and thereof by the Company and its subsidiaries do not and shall not: (a) conflict with or violate any 
provision of applicable Law or any ruling, writ, injunction, order, permit, judgment or decree of any Governmental Authority, 
(b) constitute a breach of, or default under (or an event which, with notice or lapse of time or both, would become a default 
under) or conflict with, or give rise to any right of termination, cancellation or acceleration of, any agreement, arrangement or 
instrument, whether written or oral, by which the Company, any of its subsidiaries or any of its assets are bound, (c) result in 
any encumbrance upon any of the Shares, other than restrictions on resale pursuant to securities Laws, or (d) violate or conflict 
with any of the provisions of the Organizational Documents or any subsidiary’s organizational documents, except, in the case

4.13 Intellectual Property.

(a)  “Company Intellectual Property” means all Intellectual Property owned (or purported to be 

owned) by the Company and/or its Affiliates in the operation of its business as presently conducted or reasonably expected to be 
conducted. Schedule 11.2 of the Collaboration Agreement sets forth a complete and accurate list of (a) all Wave Background 
Patents issued or pending as of the Execution Date, including (i) for each such Patent that is owned by Wave or its Affiliates, 
whether it is solely or jointly owned, and, further if jointly owned, the identity of the Third Party joint owner(s), and (ii) for each 
such Patent that is in licensed by Wave or its Affiliates, the identity of the Third Party owner, the corresponding Existing Wave 
Third Party Agreements or SERPINA1 Collaboration In License, as applicable pursuant to which such Patent is Controlled by 
Wave, and whether such Patent is licensed to Wave exclusively or non exclusively; and (b) all license, assignment, distribution, 
or other agreements pursuant to which Wave or its Affiliates Control (or has the right to obtain Control of), or otherwise is 
granted rights to, any Wave Background Technology, including all Existing Wave Third Party Agreements.  Wave has provided

its counterparty from such copies, except to the extent that such information is required in order for GSK to identify the 
obligations with which it or its Related Parties will be required to comply).  For clarity, Schedule 11.2 of the Collaboration 
Agreement does not necessarily include all Company Intellectual Property.  The Company Intellectual Property is owned free 
from any material liens, charges, encumbrances or restrictions.  All of the Company’s material Intellectual Property Licenses are 
in full force and effect in accordance with their terms, are free of any material liens or restrictions, and neither the Company nor 
to the Company’s knowledge any other party thereto, is in material breach of any such material Intellectual Property License, and 
to the Company’s knowledge no event has occurred that with notice or lapse of time or both would constitute such a material 
breach thereunder or would result in the termination thereof or would cause or permit the acceleration or other change of any 
material right or obligation of the loss of any material benefit thereunder by the Company.  Neither the execution, delivery nor 
performance of this Agreement or the other agreements and documents contemplated hereby to be executed and delivered by the 
Company, as applicable, nor the consummation of the transactions contemplated hereby or thereby, shall adversely impact (or 
require the payment or grant of additional amounts of consideration), result in the loss, forfeiture, cancellation, suspension, 
limitation, termination or other impairment of, or give rise to any right of any Third Party or other person to cancel, suspend, 
limit, terminate or otherwise impair the right of the Company or any of its Affiliates to own or use or otherwise exercise any 
other rights that the Company or any of its Affiliates currently has with respect to, any of the Intellectual Property currently used 
in their businesses, or require the consent or authorization of any Person in respect of the right of the Company or any of its 
Affiliates to own or use otherwise exercise any other rights that the Company or any of its Affiliates currently has with respect to 
any such Intellectual Property.  

(b)  The Company and its Affiliates have taken reasonable measures to protect and maintain such 

Company Intellectual Property, consistent with prudent commercial practices in the biotechnology industry.  The Company and 
its Affiliates have taken reasonable precautions to preserve the confidentiality of any confidential Know-How included in the 
Company Intellectual Property.

obtained  or  is  being  used  by  the  Company  or  any  of  its  Affiliates  in  violation  of  any  contractual  obligation  binding  on  the 
Company or its Affiliates or any of their respective officers, directors or employees or otherwise in violation of the rights of any 
Persons.  The product candidates that are under development by the Company or any Affiliates fall within the scope of the claims 
of one or more Patents within the Company Intellectual Property.

Background Technology; and (ii) use, disclose, and commercially exploit, and to enable GSK and its Related Parties to use, 
disclose, and commercially exploit (in each case under appropriate conditions of confidentiality) the Wave Background 
Technology in accordance with this Agreement.  Without limiting the generality of the foregoing, Wave or its Affiliate has 
obtained all necessary consents and fulfilled all necessary conditions applicable to Wave (and other than those conditions 
required to be flowed through to GSK), if any, to grant to GSK the license and sublicense rights provided in the present 
Agreement.

(f)  Wave has not granted its Affiliates or any Third Party, including any academic organization or 
agency, rights that would otherwise interfere or be inconsistent with GSK’s rights hereunder, and there are no agreements or 
arrangements to which Wave or any of its Affiliates is a party relating to Wave Technology or Collaboration Compounds or 
Collaboration Products directed to any Collaboration Target, that would (a) limit the rights granted to GSK under this Agreement

employee of Wave or its Affiliate is subject to any agreement with any other Third Party that requires such officer or employee to 
assign any interest in any Wave Background Technology to any Third Party.  Except as otherwise provided in Schedule 11.2 of 
the Collaboration Agreement, Wave is the sole owner of the Wave Background Patents and no Third Party has challenged or is 
challenging Wave’s ownership thereof.  The Wave Background Patents are free and clear of any liens, charges, and encumbrances 
that would conflict with the rights granted under this Agreement.

(i)  All employees, officers, and consultants of Wave and its Affiliates have executed agreements or 
have existing obligations under Applicable Law and obligating the individual to maintain as confidential Wave’s Confidential 
Information as well as confidential information of other parties (including of GSK and its Affiliates) that such individual may 
receive in the conduct of this Agreement, to the extent required to support Wave’s obligations under this Agreement; and Wave 
and its Affiliates have taken all reasonable precautions to preserve the confidentiality of the Wave Background Know How.

(j)  Neither Wave nor its Affiliates have entered into a government funding relationship that would 

result in rights to any Collaboration Compound or Collaboration Product directed to any Collaboration Target residing in the US 
Government, National Institutes of Health, National Institute for Drug Abuse or other agency, and the licenses granted hereunder 
are not subject to overriding obligations to the US Government as set forth in Public Law 96 517 (35 U.S.C. 200 204), as 
amended, or any similar obligations under the laws of any other country.

diligently prosecuted and maintained.  There are no oppositions, nullity actions, interferences, inter partes reexaminations, inter 
partes reviews, post grant reviews, derivation proceedings, or other proceedings pending or threatened (but excluding office 
actions or similar communications issued by any Patent Offices in the ordinary course of prosecution of any patent application) 
that challenge the scope, validity, or enforceability of the Wave Background Patents.  Wave has filed and prosecuted patent 
applications within the Wave Background Patents in good faith and, has complied with all duties of disclosure with respect 
thereto.  Other than through filing of terminal disclaimers in the ordinary course of patent prosecution, Wave has not committed 
any act, or omitted to commit any act, that may cause the Wave Background Patents to expire prematurely or be declared invalid 
or unenforceable.  Wave or its Affiliates have timely paid all application, registration, maintenance, and renewal fees in respect of 
the Wave Background Patents and have filed with the United States Patent and Trademark Office or any analogous foreign 
Governmental Authority (collectively, “Patent Offices”) all necessary documents and certificates for the purpose of maintaining 
such Wave Background Patents.

(l)  The owned Wave Technology and, to Wave’s knowledge, the in licensed Wave Technology is not 

subject to, any judgment or settlement that would reasonably be expected to materially restrict the use thereof or otherwise would 
reasonably be expected to adversely affect the validity or enforceability thereof.  To Wave’s knowledge, no Third Party has

(m)  To Wave’s knowledge, the Exploitation of any Collaboration Compound or Collaboration Product 

directed to any Collaboration Target, in each case, as contemplated hereunder does not infringe any valid patent rights of any 
Third Party.  There are no claims, demands, suits, proceedings, arbitrations, or other legal actions of any nature, civil, criminal, 
regulatory or otherwise, pending or, to Wave’s knowledge, threatened against Wave or any of its Related Parties alleging or

2.  Registration Rights.

2.1  Demand Registration.

(a)  Subject to the provisions hereof, after the Restricted Term, the Investor and any Permitted 

Transferee of the Investor (each a “Holder”) holding, collectively, a majority of the Registrable Securities then outstanding shall 
have the right to require the Company to file a Registration Statement registering for sale all or part of the Shares held by or 
issuable to them (collectively, the “Registrable Securities”) under the Securities Act (a “Demand Registration”) by delivering a 
written request therefor to the Company (i) specifying the number of Registrable Securities to be included in such registration by 
such Holder or Holders, (ii) specifying whether the intended method of disposition thereof is pursuant to an underwritten public 
offering of Ordinary Shares by the Company (an “Underwritten Offering”), and (iii) containing all information about such 
Holder required to be included in such Registration Statement in accordance with applicable Law.  The Company shall use 
commercially reasonable efforts to effect such registration (including, without limitation, appropriate qualification under 
applicable blue sky or other state securities Laws and appropriate compliance with applicable regulations issued under the 
Securities Act and any other governmental requirements or regulations) of the Registrable Securities that the Company has been 
so requested to register as soon as practicable (and in any case by the applicable Filing Date); provided, however, that the 
Holders shall not make a request for a Demand Registration under this Section 2.1(a) for Registrable Securities having an 
anticipated aggregate offering price of less than $25,000,000.  The Holders shall be entitled to require the Company to effect two 
(2) Demand Registrations under this Agreement.

(b)  If the offering of the Registrable Securities pursuant to such Demand Registration is an 

Underwritten Offering, (i) the Company shall select the underwriter(s) of the Underwritten Offering, subject to the approval of 
the Holders of a majority of the Registrable Securities to be sold in the Underwritten Offering, such approval not to be 
unreasonably withheld, conditioned or delayed, and (ii) the Company shall (together with the Holders proposing to distribute 
their securities through such underwriting) enter into an underwriting agreement in customary form for underwriting agreements 
for firm commitment offerings by a selling holder of equity securities with the managing underwriter(s) proposing to distribute 
their securities through such Underwritten Offering; provided, that (i) the representations and warranties by, and the other 
agreements on the part of, the Company to and for the benefit of the underwriter(s) shall also be made to and for the benefit of the 
Holders proposing to distribute their securities through the Underwritten Offering, (ii) no Holder shall be required to make any 
representations and warranties to, or agreements with, any underwriter in a registration other than customary representations, 
warranties and agreements and (iii) the liability of each Holder in respect of any indemnification, contribution or other obligation 
of such Holder arising under such underwriting agreement (a) shall be limited to losses arising out of or based upon an untrue 

6

 
 
 
statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, any such preliminary 
Prospectus, final Prospectus, summary Prospectus, amendment or supplement, incorporated document or other such disclosure 
document or other document or report, in reliance upon and in conformity with written information furnished to the Company by 
or on behalf of such Holder expressly for inclusion therein and (b) shall not in any event, absent fraud or intentional 
misrepresentation, exceed an amount equal to the net proceeds to such Holder (after deduction of all underwriters’ discounts and 
commissions) from the disposition of the Registrable Securities disposed of by such Holder pursuant to such Underwritten 
Offering.

(c)  If, in connection with a Demand Registration in the form of an Underwritten Offering, the 

managing underwriter(s) give written advice to the Company of the number of securities to which such registration should, in the 
opinion of the managing underwriter(s) of such registration, in light of marketing factors, be limited (an “Underwriters’ 
Maximum Number”), then the Company shall (i) so advise all Holders of Registrable Securities to be included in such 
Underwritten Offering and (ii) include in such registration the number of securities requested to be included in such registration 
by all Holders of Registrable Securities to be included in such Underwritten Offering, pro rata on the basis of the aggregate 
number of Registrable Securities requested to be included by each such Holder, and, subject to the conditions set forth in Section 
2.8 hereto, on a pari passu basis with the holders of contractual registration rights provided under (i) the Investor Agreement, 
dated as of April 2, 2018, by and between the Company and Takeda Pharmaceutical Company Limited (the “Takeda Holders”) 
and (ii) the Share Purchase Agreement by and between the Company and C.P. Pharmaceuticals International C.V. dated as of May 
6, 2016 (the “Pfizer Holders”).

(d)  A registration will not be deemed to have been effected as a Demand Registration unless the 

Registration Statement relating thereto has been declared effective by the SEC, at least seventy five percent (75%) of the 
Registrable Securities requested to be included in the registration by the Holders are included in such registration, and the 
Company has complied in all material respects with its obligations under this Agreement with respect thereto; provided, however, 
that if, after it has become effective, (i) such Registration Statement or the related offer, sale or distribution of Registrable 
Securities thereunder is or becomes the subject of any stop order, injunction or other order or requirement of the SEC or any other 
governmental or administrative agency, or if any court prevents or otherwise limits the sale of the Registrable Securities pursuant 
to the registration (each, an “Interference”), which Interference does not result from any act or omission of any Holder whose 
Registrable Securities are registered pursuant to such Registration Statement and is not cured within forty five (45) days thereof, 
and (ii) in each case less than seventy five percent (75%) of the Registrable Securities covered by the effective Registration 
Statement are actually sold by the selling Holder or Holders pursuant to the Registration Statement, then such registration will be 
deemed not to have been effected for purposes of the last sentence of Section 2.1(a).  If (i) a registration requested pursuant to 
this Section 2.1 is deemed not to have been effected as a Demand Registration or (ii) the registration requested pursuant to this 
Section 2.1 does not remain continuously effective until the completion of the distribution by the Holders of the Registrable 
Securities covered by such registration, then the Company shall continue to be obligated to effect a Demand Registration 
pursuant to this Section 2.1 of the Registrable Securities included in such registration.  In circumstances not including the events 
described in the immediately two preceding sentences of this Section 2.1(d), each Holder of Registrable Securities shall be 
permitted voluntarily to 

7

 
 
 
withdraw all or any part of its Registrable Securities from a Demand Registration at any time prior to the commencement of 
marketing of such Demand Registration, provided that such registration nonetheless shall count as a Demand Registration for 
purposes of the last sentence of Section 2.1(a).

2.2  Piggyback Registration.

(a)  After the Restricted Term, if (and on each occasion that) the Company proposes to register any of 

its securities under the Securities Act, including if the Company qualifies as a well-known seasoned issuer (within the meaning of 
Rule 405 under the Securities Act) (a “WKSI”) (other than (i) pursuant to Section 2.1, (ii) in connection with registrations on 
Form S-4 or S-8 promulgated by the SEC or any successor or similar forms, (iii) in connection with a transaction conducted 
pursuant to Rule 145 of the Securities Act, (iv) in connection with registrations on any registration form that does not permit 
secondary sales or does not include substantially the same information as would be required to be included in a registration 
statement covering the sale of Registrable Securities or (v) in connection with a shelf registration statement for the sale of 
ordinary shares for its own account in a “registered direct” offering or at-the-market (“ATM”) offering program), whether for its 
own account or the account of any of its security holders (each such registration not withdrawn or abandoned prior to the 
effective date thereof being herein referred to as a “Piggyback Registration”), the Company shall give written notice to the 
Holders of such proposal promptly, but in no event later than ten (10) Business Days prior to the anticipated filing date.  Each 
Holder shall keep confidential and not disclose to any Third Party its receipt of any such notice and any information regarding 
such proposed offering.

(b)  Subject to the provisions contained in paragraphs (a) and (c) of this Section 2.2 and the last 
sentence of this paragraph (b), the Company will be obligated and required to include in each Piggyback Registration such 
Registrable Securities as requested in a written notice from any Holder delivered to the Company no later than ten (10) Business 
Days following delivery of the notice from the Company specified in Section 2.2(a).  If a Piggyback Registration is an 
Underwritten Offering, the Company shall (together with the Holders proposing to distribute their securities through such 
underwriting) enter into an underwriting agreement with the managing underwriter(s) in customary form for underwriting 
agreements for such an offering.  The Company may terminate or withdraw any Piggyback Registration prior to the effectiveness 
of such registration, whether or not the Holders have elected to include Registrable Securities in such registration.

(c)  If a Piggyback Registration is an Underwritten Offering on behalf of a holder of Company 

securities other than Holders (including, for the avoidance of doubt, the Takeda Holders or the Pfizer Holders), and the managing 
underwriter(s) advise the Company that in their reasonable opinion the number of securities proposed to be included in such 
registration exceeds the Underwriters’ Maximum Number, then the Company shall include in such registration (i) first, the 
number of securities to be sold by the Company (if any), (ii) second, the number of securities requested to be included therein by 
such holder(s) requesting such registration, (iii) third, the number of securities requested to be included therein by all Holders 
who have requested registration of Registrable Securities in accordance with Section 2.2(a), pro rata on the basis of the aggregate 
number of Registrable Securities requested to be 

8

 
 
 
included by each such Holder, and, subject to the conditions set forth in Section 2.8 hereto, on a pari passu basis with the Takeda 
Holders and the Pfizer Holders, and (iv) fourth, any other securities that have been requested to be so included by any other 
Person.  If a Piggyback Registration is an Underwritten Offering on behalf of the Company, and the managing underwriter(s) 
advise the Company that in their reasonable opinion the number of securities proposed to be included in such registration exceeds 
the Underwriters’ Maximum Number, then the Company shall include in such registration (i) first, the number of securities to be 
sold by the Company, (ii) second, the number of securities requested to be included therein by holder(s) with priority over the 
Holders with respect to such registration, (iii) third, the number of securities requested to be included therein by all Holders who 
have requested registration of Registrable Securities in accordance with Section 2.2(a), pro rata on the basis of the aggregate 
number of Registrable Securities requested to be included by each such Holder, and, subject to the conditions set forth in Section 
2.8 hereto, on a pari passu basis with the Takeda Holder and the Pfizer Holders, and (iv) fourth, any other securities that have 
been requested to be so included by any other Person.

to select the managing underwriter(s) for such registration.

(d)  In any Piggyback Registration that is an Underwritten Offering, the Company shall have the right 

2.3  Registration Expenses.  In connection with registrations pursuant to Section 2.1 or Section 2.2 hereof, 

the Company shall pay all of the costs and expenses incurred in connection with the registrations thereunder (the 
“Registration Expenses”), including all (i) registration and filing fees and expenses, including, without limitation, those 
related to filings with the SEC, (ii) fees and expenses of compliance with state securities or blue sky Laws (including 
reasonable fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities), (iii) 
reasonable processing, duplicating and printing expenses, including expenses of printing Prospectuses reasonably requested 
by any Holder, (iv) the Company’s internal expenses (including, without limitation, all salaries and expenses of its officers and 
employees performing legal or accounting duties, the expense of any liability insurance and the expense of any annual audit or 
quarterly review), (v) fees and expenses incurred in connection with listing the Registrable Securities for trading on a national 
securities exchange, (vi) fees and expenses in connection with the preparation of the registration statement and related 
documents covering the Registrable Securities, (vii) fees and expenses, if any, incurred with respect to any filing with FINRA, 
(viii) any documented out-of-pocket expenses of the underwriter(s) incurred with the approval of the Company, (ix) the cost 
of providing any CUSIP or other identification numbers for the Registrable Securities, (x) fees and expenses and 
disbursements of counsel for the Company and fees and expenses for independent certified public accountants retained by the 
Company (including, without limitation, the expenses of any comfort letters or costs associated with the delivery by 
independent certified public accountants of a comfort letter or comfort letters requested), (xi) fees and expenses of any special 
experts retained by the Company in connection with such registration, and (xii) reasonable and documented fees and expenses 
of one firm of counsel for the Holders to be selected by the Holders of a majority of the Registrable Securities to be included 
in such registration (“Holders’ Counsel”) not to exceed $75,000 per registration. Notwithstanding the foregoing, the Holders 
shall be responsible, on a pro rata basis based on the number of Registrable Securities included in the applicable registered 
offering by each such Holder, for any underwriting discounts, commissions and share transfer fees attributable 

9

 
 
 
to the sale of Registrable Securities pursuant to a Registration Statement and any other out-of-pocket expenses of the Holders 
not required to be paid by the Company pursuant to this Section 2.3.  The obligation of the Company to bear the expenses 
described in this Section 2.3 and to pay or reimburse the Holders for the expenses described in this Section 2.3 shall apply 
irrespective of whether any sales of Registrable Securities ultimately take place; provided, however, that the Company shall 
not be required to pay any expenses of any Demand Registration if the registration request is subsequently withdrawn at the 
request of the Holders of a majority of the Registrable Securities to be registered (in which case all selling Holders shall bear 
such expenses on a pro rata basis based on the number of Registrable Securities included in the applicable registered offering 
by each such Holder). 

2.4  Registration Procedures.  In the case of each registration effected by the Company pursuant to this 
Agreement, the Company shall keep each Holder advised in writing as to the initiation of each registration and as to the 
completion thereof.  In connection with any such registration:

number of copies of such Registration Statement, each amendment and supplement thereto (in each case including all exhibits 
thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each 
preliminary Prospectus) and such other documents or information as such Holder, Holders’ Counsel or the underwriter(s) may

registration or qualification (or exemption therefrom) effective during the period which the Registration Statement is required to 
be kept effective pursuant to the terms hereof; provided that the Company will not be required to (i) qualify generally to do 
business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph (f), (ii) subject itself to 
taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction.

changes in a Registration Statement or related Prospectus or any document incorporated or deemed to be incorporated by 
reference therein so that they will not contain any untrue statement of a material fact or omit to state any material fact required to 
be stated therein or necessary to make the statements in the Registration Statement and Prospectus not misleading in the light of 
the circumstances in which they were made; and, as promptly as practicable thereafter, prepare and file with the SEC and furnish 
a supplement or amendment to such Prospectus so that, as thereafter deliverable to the purchasers of such Registrable Securities, 
such Prospectus will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the 
statements therein, in the light of the circumstances under which they were made, not misleading.

such Holder’s ownership of ordinary shares and authority to enter into the underwriting agreement and to such Holder’s intended 
method of distribution, and the liability of such Holder shall be several and not joint, and limited to an amount equal to the net

outstanding automatic shelf registration statement used to effect a request for registration in accordance with Section 2.2 the 
Company determines that it is not a WKSI and (i) the registration statement is required to be kept effective in accordance with 
this Agreement and (ii) the registration rights of the applicable Holders have not terminated, use reasonable best efforts to 
promptly amend the registration statement on a form the Company is then eligible to use or file a new registration statement on

Section 2.4(g) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Registration 
Statement covering such Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended 
Prospectus contemplated by Section 2.4(g) hereof, and, if so directed by the Company, such Holder will deliver to the 
Company all copies, other than permanent file copies then in such Holder’s possession and retained solely in accordance with 
record retention policies then-applicable to such Holder, of the most recent Prospectus covering such Registrable Securities at 
the time of receipt of such notice.

written notice to the participating Holders (a “Suspension Notice”) stating which one or more of the following limitations 
shall apply to the addressee of such Suspension Notice, the Company may (i) postpone effecting a registration under this 
Agreement, or (ii) require such addressee to refrain from disposing of Registrable Securities under the registration, in either 
case for a period of no more than ninety (90) consecutive days from the delivery of such Suspension Notice (which period 
may not be extended or renewed).  The Company may postpone effecting a registration or apply the limitations on 
dispositions specified in clause (ii) of this Section 2.6 if (x) within ninety (90) days of receipt of a request for Demand 
Registration under Section 2.1(a), the Company has a good faith expectation to file a registration statement for the public 
offering of securities for the account of the Company, provided, that the Company is actively employing good faith efforts to 
cause such registration statement to become effective, (y) the Company’s Board of Directors, in good faith, determines that 
such registration or disposition would materially impede, delay or interfere with any material transaction then pending or 
proposed to be undertaken by the 

13

 
 
 
Company or any of its subsidiaries, or (z) the Company in good faith determines that the Company is in possession of material 
non-public information the disclosure of which during the period specified in such notice the Company’s Board of Directors, 
in good faith, reasonably believes would be materially detrimental to the Company; provided, that the Company may not take 
any actions pursuant to this Section 2.6 more than twice in any twelve (12)-month period.  Furthermore, the Company shall 
not be required to effect any registration of Registrable Securities at any time during the period any Holder is in breach of or 
has failed to cause its Affiliates to comply with the obligations and restrictions of Sections 3 or 4 of this Agreement, the 
Company has provided notice of such breach to such Holder, and such breach or failure is ongoing and has not been remedied.

2.7  Indemnification. 

(a)  Indemnification by the Company.  The Company agrees to indemnify and hold harmless each 
Holder including Registrable Securities in any registration statement filed pursuant to this Section 2 and each of its officers, 
directors, employees and agents, and each Person, if any, who controls such Holder within the meaning of Section 15 of the 
Securities Act or Section 20 of the Exchange Act, together with the officers, directors, employees and agents of such controlling 
Person (each, a “Controlling Person”), from and against any and all losses, claims, damages, settlement amounts (only if the 
Company consented in writing to the settlement, which consent shall not be unreasonably withheld), liabilities, reasonable 
attorneys’ fees, costs and expenses of investigating and defending any such claim (collectively, “Damages”) and any action in 
respect thereof to which such Holder, its Controlling Persons and their respective officers, directors, employees and agents may 
become subject to under the Securities Act or otherwise, insofar as such Damages (or proceedings in respect thereof) arise out of, 
or are based upon, any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or 
Prospectus (or any amendment or supplement thereto) or any preliminary Prospectus of the Company, or arise out of, or are based 
upon, any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the 
statements therein not misleading in the light of the circumstances in which they were made, except insofar as (i) the same are 
based upon information furnished in writing to the Company by such Holder, any of its Controlling Persons, or any of their 
respective officers, directors, employees and agents expressly for use therein, and (ii) any Damages are caused by such Holder’s 
disposition of Registrable Securities during any period during which such Holder is obligated to discontinue any disposition of 
Registrable Securities as a result of any stop order suspending the effectiveness of any Registration Statement or Prospectus with 
respect to Registrable Securities of which such Holder has received written notice from the Company.  The Company shall 
reimburse such Holder for any legal and other expenses reasonably incurred in investigating or defending or preparing to defend 
against any such Damages or proceedings.  In addition to the indemnity contained herein, the Company will reimburse each such 
Person for its reasonable out-of-pocket legal and other expenses (including the reasonable out-of-pocket cost of any investigation, 
preparation and travel in connection therewith) as incurred in connection therewith, as promptly as practicable after such 
expenses are incurred and invoiced.

hold harmless the Company, its officers, directors, employees and agents and each Person, if any, who controls the Company 
within the meaning of Section 15 of 

(b)  Indemnification by the Holders.  Each Holder agrees, severally and not jointly, to indemnify and 

14

 
 
 
the Securities Act or Section 20 of the Exchange Act, together with the officers, directors, employees and agents of such 
Controlling Person, to the same extent as the foregoing indemnity from the Company to each Holder, but only with respect to 
information related to such Holder, its Controlling Persons or its plan of distribution, furnished in writing by such Holder, its 
Controlling Persons or any of their respective officers, directors, employees and agents to the Company expressly for use in any 
Registration Statement or Prospectus, or any amendment or supplement thereto, or any preliminary Prospectus.  In addition to the 
indemnity contained herein, such Holder will reimburse the Company for its reasonable out-of-pocket legal and other expenses 
(including the reasonable out-of-pocket cost of any investigation, preparation and travel in connection therewith) as incurred in 
connection therewith, as promptly as practicable after such expenses are incurred and invoiced.

(c)  Conduct of Indemnification Proceedings.  Promptly after receipt by any Person entitled to 

indemnification pursuant to Section 2.7(a) or Section 2.7(b) (an “Indemnified Party”) of notice of any claim or the 
commencement of any action in respect of which indemnity may be sought pursuant to Section 2.7(a) or Section 2.7(b), the 
Indemnified Party shall, if a claim in respect thereof is to be made against the Person against whom such indemnity may be 
sought (an “Indemnifying Party”), notify the Indemnifying Party in writing of the claim or the commencement of such action; 
provided, that the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have to an Indemnified 
Party other than under Section 2.7(a) or Section 2.7(b) except to the extent of any actual prejudice resulting therefrom.  If any 
such claim or action shall be brought against an Indemnified Party, and it shall notify the Indemnifying Party thereof, the 
Indemnifying Party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly 
notified Indemnifying Party, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party.  After 
notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim or action, the 
Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the 
Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, that the 
Indemnified Party shall have the right to employ separate counsel to represent the Indemnified Party and its Controlling Persons 
who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party 
against the Indemnifying Party, but the fees and expenses of such counsel shall be for the account of such Indemnified Party 
unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of, and reimbursement of 
fees for, such counsel or (ii) in the reasonable opinion of counsel to such Indemnified Party representation of both parties by the 
same counsel would be inappropriate due to actual or potential conflicts of interest between them, it being understood, however, 
that the Indemnifying Party shall not, in connection with any one such claim or action or separate but substantially similar or 
related claims or actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the 
fees and expenses of more than one separate firm of attorneys (together with appropriate local counsel) at any time for all 
Indemnified Parties.  No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any 
settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or would reasonably 
have been a party and indemnity would reasonably have been sought hereunder by such Indemnified Party, unless such 
settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.  
Whether or not the defense of any claim or action is assumed by the 

15

 
 
 
Indemnifying Party, such Indemnifying Party will not be subject to any liability for any settlement made without its written 
consent.

2.8  Limitations on Subsequent Registration Rights.  From and after the date of this Agreement, the Company 
shall not enter into any agreement granting any holder or prospective holder of any Company securities (i) registration rights in 
the nature or substantially in the nature of those set forth in Sections 2.1 and 2.2 that would have priority over the Registrable 
Securities with respect to inclusion of such securities in any Demand Registration or Piggyback Registration or (ii) demand 
registration rights or piggyback registration rights in the nature or substantially in the nature of those set forth in Sections 2.1 and 
2.2, respectively, that are exercisable earlier than 30 months from the date the Company securities are issued to the prospective 
holder.

2.9  Assignment of Registration Rights.  The rights to cause the Company to register any Registrable Securities 

pursuant to this Agreement may be assigned in whole or in part (but only with all restrictions and obligations set forth in this 
Agreement) by a Holder to a Permitted Transferee which acquires Registrable Securities from such Holder; provided, however, 
(a) such Holder shall, within five (5) days prior to such transfer, furnish to the Company written notice of the name and address 
of such Permitted Transferee, details of its status as a Permitted Transferee and details of the Registrable Securities with respect 
to which such registration rights are being assigned, (b) the Permitted Transferee, prior to or simultaneously with such transfer or 
assignment, shall agree in writing to be subject to and bound by all restrictions and obligations set forth in this Agreement, (c) the 
Investor shall continue to be bound by all restrictions and obligations set forth in this Agreement and (d) such transfer or 
assignment shall be effective only if immediately following such transfer or assignment the further disposition of such 
Registrable Securities by the Permitted Transferee is restricted under the Securities Act and other applicable securities Law.

3.  Restrictions on Beneficial Ownership.

3.1  Standstill.  During the 30-month period after the date of this Agreement (such period, the “Restricted

Affiliates not to), except as expressly approved or invited in writing by the Company:

(a)  directly or indirectly, acquire beneficial ownership of Then Outstanding Ordinary Shares and/or

Directors any Then Outstanding Ordinary Shares;

16

 
 
 
(c)  directly or indirectly, encourage or support a tender, exchange or other offer or proposal by any 

other Person (an “Offeror”) the consummation of which would result in a Change of Control of the Company (an “Acquisition 
Proposal”); provided, however, that from and after the filing of a Schedule 14D-9 (or successor form of Tender Offer 
Solicitation/Recommendation Statement under Rule 14d-9 of the Exchange Act) by the Company recommending that 
shareholders accept any such offer, Investor shall not be prohibited from taking any of the actions with respect to such offer 
otherwise prohibited by this Section 3.1(c) for so long as the Company maintains and does not withdraw such recommendation;

(d)  directly or indirectly, solicit proxies or consents or become a participant in a solicitation (as such 

terms are defined in Regulation 14A under the Exchange Act) in opposition to the recommendation of a majority of the

an “Extraordinary Matter”);

(g)  act in concert with any Third Party to take any action in clauses (a) through (e) above, or form,

foregoing actions referred to in (a) through (f) above; or

(h)  enter into discussions, negotiations, arrangements or agreements with any Person relating to the 

(i) 

request or propose to the Company’s Board of Directors, any member(s) thereof or any officer of 
the Company that the Company amend, waive, or consider the amendment or waiver of, any provisions set forth in this Section 
3.1 (including this clause (i)); provided, however, that the Investor may make such requests or proposals privately to the 
Company’s directors, officers or advisors if the Company executes, or publicly announces its intention to execute, a collaboration 
and licensing agreement, strategic alliance or similar transaction with a third party so long as, in each case, such requests or 
proposals are not intended to, and would not reasonably be expected to, require any public disclosure by the Company or the 
Investor of such requests or proposals, as applicable; 

Notwithstanding anything to the contrary in this Section 3.1, the Investor may at any time communicate privately with the 
Company’s directors, officers or advisors or submit to the Company’s Board of Directors one or more confidential proposals or 
offers for a transaction (including a transaction that, if consummated, would result in a Change of Control), so long as, in each 
case, such communications and submissions are not intended to, and would not

reasonably be expected to, require any public disclosure by the Company or the Investor of such communications or submissions, 
as applicable.

dividend or other distribution with respect to, or in exchange or in replacement of, the Ordinary Shares described in clause (x) of

6.13 Remedies.  The rights, powers and remedies of the parties under this Agreement are cumulative and not 

exclusive of any other right, power or remedy which such parties may have under any other agreement or Law.  No single or 
partial assertion or exercise of any right, power or remedy of a party hereunder shall preclude any other or further assertion or 
exercise thereof.

6.14 Specific Performance.  The Company and the Investor hereby acknowledge and agree that the rights of the 

parties hereunder are special, unique and of extraordinary character, and that if any party refuses or otherwise fails to act, or to 
cause its Affiliates to act, in accordance with the provisions of this Agreement, such refusal or failure would result in irreparable 
injury to the Company or the Investor, as the case may be, the exact amount of which would be difficult to ascertain or estimate 
and the remedies at law for which would not be reasonable or adequate compensation.  Accordingly, if any party refuses or 
otherwise fails to act, or to cause its Affiliates to act, in accordance with the provisions of this Agreement, then, in addition to any 
other remedy which may be available to any damaged party at law or in equity, such damaged party will be entitled to seek 
specific performance and injunctive relief, without posting bond or other security, and without the necessity of proving actual or 
threatened damages, which remedy such damaged party will be entitled to seek in any court of competent jurisdiction.

6.15 No Conflicting Agreements.  The Investor hereby represents and warrants to the Company that neither it 

nor any of its Affiliates is, as of the date of this Agreement, a party to, and agrees that neither it nor any of its Affiliates shall, on 
or after the date of this Agreement, enter into any agreement that conflicts with the rights granted to the Company in this 
Agreement.  The Company hereby represents and warrants to each Holder that it is not, as of the date of this Agreement, a party 
to, and agrees that it shall not, on or after the date of this Agreement, enter into, any agreement or approve any amendment to its 
Organizational Documents (as defined in the Purchase Agreement) with respect to its securities that conflicts with the rights 
granted to the Holders in this Agreement.  The Company further represents and warrants that the rights granted to the Holders 
hereunder do not in any way conflict with the rights granted to any other holder of the Company’s securities under any other 
agreements.

EXECUTIVE EMPLOYMENT AGREEMENT

Exhibit 10.12

This  Employment  Agreement  (the  “Agreement”),  made  and  entered  into  as  of  November  8,  2022,  by  and  between  Wave
Life  Sciences  USA,  Inc.,  a  Delaware  corporation  (“Company”)  and  a  wholly  owned  subsidiary  of  Wave  Life  Sciences  Ltd.,  a 
Singapore corporation (the “Parent Company”), and Chris Francis (“Executive”). 

WHEREAS, Company wishes to continue to employ Executive as SVP, Corporate Development and Head of Emerging 

Areas;

WHEREAS, Executive represents that Executive possesses the necessary skills to perform the duties of this position and 
that Executive has no obligation to any other person or entity which would prevent, limit or interfere with Executive’s ability to 
do so;

WHEREAS, Executive and Company desire to enter into an Employment Agreement, which, except as specifically set 
forth herein, supersedes and replaces the current employment arrangement dated as of March 10, 2014, between Executive and 
Company (the “Prior Employment Agreement”), to assure the harmonious performance of the affairs of Company.

NOW, THEREFORE, in consideration of the mutual promises, terms, provisions, and conditions contained herein, the 

parties agree as follows:  

1.  Roles and Duties.  

(a)  Executive Role.    Subject  to  the  terms  and  conditions  of  this  Agreement,  Company  shall  employ  Executive  as  its 
SVP,  Corporate  Development  and  Head  of  Emerging  Areas  reporting  to  Company’s  President  and  Chief  Executive  Officer. 
Executive  accepts  such  employment  upon  the  terms  and  conditions  set  forth  herein,  and  agrees  to  perform  to  the  best  of 
Executive’s ability the duties normally associated with such position and as determined by Company in its sole discretion. During 
Executive’s  employment,  Executive  shall  devote  all  of  Executive’s  business  time  and  energies  to  the  business  and  affairs  of 
Company,  provided  that  nothing  contained  in  this  Agreement  shall  prevent  or  limit  Executive’s  right  to  manage  Executive’s 
personal investments on Executive’s own personal time, including, without limitation the right to make passive investments in the 
securities of: (a) any entity which Executive does not control, directly or indirectly, and which does not compete with Company 
or  the  Parent  Company,  or  (b)  any  publicly  held  entity  so  long  as  Executive’s  aggregate  direct  and  indirect  interest  does  not 
exceed two percent (2%) of the issued and outstanding securities of any class of securities of such publicly held entity.  Nothing 
contained  herein  shall  prevent  any  family  member  of  Executive  from  contracting  with,  being  employed  by  or  obtaining  an 
ownership  interest  in  any  entity,  whether  or  not  such  entity  competes  with  the  Company  or  the  Parent  Company;  provided, 
however, that such contract, employment, or ownership interest does not extend to or involve Executive.  In addition, nothing in 
this Agreement shall require Executive to transfer, sell or otherwise divest himself of any investments Executive or Executive’s 
family  members  hold  as  of  the  date  hereof.    During  Executive’s  employment,  Executive  shall  not  engage  in  any  other  non-
Company  related  business  activities  of  any  nature  whatsoever  (including  board  memberships)  without  the  Company’s  prior 
written consent, which consent shall not be unreasonably withheld.  In addition, and so long as such activities do not interfere 
with Executive’s performance of Executive’s duties hereunder (including Executive’s full devotion of business time and energies 
to the business and affairs of Company, as described above), Executive also may participate in civic, charitable and professional 
activities, but shall not serve in any official capacity, including as a member of a board, without the  prior written consent of the 
Company.

 
 
 
 
 
 
 
 
2.  Term of Employment.

(a)  Term.  Subject to the terms hereof, Executive’s employment hereunder shall commence as of the date hereof and 

shall continue until terminated hereunder by either party.

(b)  Termination. Notwithstanding anything else contained in this Agreement, Executive’s employment hereunder shall 

terminate upon the earliest to occur of the following:

(i)  Death.  Immediately upon Executive’s death;

(ii)  Termination by Company.

(A)  If because of Executive’s Disability (as defined below in Section 2(c)), written notice by Company 
to  Executive  that  Executive’s  employment  is  being  terminated  as  a  result  of  Executive’s  Disability,  which 
termination shall be effective on the date of such notice or such later date as specified in writing by Company;

(B)  If  for  Cause  (as  defined  below  in  Section  2(d)),  written  notice  by  Company  to  Executive  that  
Executive’s employment is being terminated for Cause, which termination shall be effective on the date of such 
notice or such later date as specified in writing by Company (subject to any applicable “cure” rights as provided 
in Section 2(d) below);

(C)  If  by  Company  for  reasons  other  than  under  Sections  2(b)(ii)(A)  or  (B),  written  notice  by  
Company to Executive that Executive’s employment is being terminated, which termination shall be effective 
immediately after the date of such notice or such later date as specified in writing by Company.

(iii)  Termination by Executive.  

(A)  If for Good Reason (as defined below in Section 2(e)), written notice by Executive to Company 
that  Executive  is  terminating  Executive’s  employment  for  Good  Reason  and  that  sets  forth  the  factual  basis 
supporting the alleged Good Reason, which termination shall be effective thirty (30) days after the date of such 
notice;  provided  that  if  Company  has  cured  the  circumstances  giving  rise  to  the  Good  Reason,  then  such 
termination shall not be effective; or

(B)  If  without  Good  Reason,  written  notice  by  Executive  to  Company  that  Executive  is  terminating  
Executive’s  employment,  which  termination  shall  be  effective  at  least  thirty  (30)  days  after  the  date  of  such 
notice.

Notwithstanding anything in this Section 2(b), Company may at any point terminate Executive’s employment for Cause 

prior to the effective date of any other termination contemplated hereunder.

(c)  Definition  of  “Disability”.    For  purposes  of  this  Agreement,  “Disability”  shall  mean  Executive’s  incapacity  or 
inability to perform Executive’s duties and responsibilities as contemplated herein for one hundred twenty (120) days or more 
(cumulative  or  consecutive)  within  any  rolling  twelve  (12)  month  period,  because  Executive’s  physical  or  mental  health  has 
become so impaired as to make it impossible or impractical for Executive to perform the duties and responsibilities contemplated 
hereunder.    Determination  of  Executive’s  physical  or  mental  health  shall  be  determined  by  Company  after  consultation  with  a 
medical  expert  appointed  by  mutual  agreement  between  Company  and  Executive  who  has  examined  Executive.    Executive 
hereby consents to such examination and consultation regarding Executive’s health and ability to perform as aforesaid.  

2

 
 
(d)  Definition of “Cause”. As used herein, “Cause” shall include: (i) Executive’s willful engagement in dishonesty, illegal 
conduct  or  gross  misconduct,  which  is,  in  each  case,  materially  injurious  to  the  Company  or  any  affiliate;  (ii)  Executive’s 
significant  insubordination;  (iii)  Executive’s  substantial  malfeasance  or  nonfeasance  of  duty;  (iv)  Executive’s  repeated  failure, 
inability or refusal to perform his duties hereunder in a manner that is materially injurious to the Company or any affiliate (other 
than by reason of Executive’s Disability); (v) Executive’s unauthorized disclosure of confidential information; (vi) Executive’s 
embezzlement, misappropriation or fraud, whether or not related Executive’s employment with the Company; or (vii) Executive’s 
breach of a material provision of any employment, non-disclosure, invention assignment, non-competition, or similar agreement 
between Executive and Company; provided that “Cause” shall not be deemed to have occurred pursuant to subsections (ii), (iii) 
or (iv) hereof unless Executive has first received written notice specifying in reasonable detail the particulars of such grounds and 
that  Company  intends  to  terminate  Executive’s  employment  hereunder  for  such  grounds,  and  if  such  grounds  are  reasonably
capable of being cured within thirty (30) days, Executive has failed to cure such grounds within a period of thirty (30) days from 
the date of such notice (the “Cure Period”).  During any such Cure Period, and in connection with Executive’s ability to cure a for 
Cause termination as specifically set forth herein, Executive shall have an opportunity to make a presentation to the Company’s 
Board  of  Directors  in  response  to  the  asserted  grounds  for  Cause  termination.    “Cause”  is  not  limited  to  events  which  have 
occurred prior to the termination of Executive’s service to Company, nor is it necessary that Company’s finding of “Cause” occur 
prior  to  such  termination.    If  Company  determines,  subsequent  to  Executive’s  termination  of  service  but  only  after  the  notice, 
related  process  and  Cure  Period  described  above  have  been  exhausted  (if  the  applicable  “Cause”  sub-section  is  invoked),  that 
either  prior  or  subsequent  to  Executive’s  termination,  Executive  engaged  in  conduct  which  would  constitute  “Cause,”  then 
Executive shall be deemed to have been terminated for “Cause” and he shall have no right to any benefit or compensation under 
this Agreement, including, without limitation, any payments or benefits under Section 4(c) or Section 4(d) hereof (as applicable).  

(e)  Definition of “Good Reason”. As used herein, a “Good Reason” shall mean the occurrence of any of the following 
events without Executive’s written consent: (i) relocation of Executive’s principal business location to a location more than fifty 
(50)  miles  from  Executive’s  then-current  business  location;  (ii)  a  material  diminution  in  Executive’s  duties,  authority  or 
responsibilities;  (iii)  a  material  reduction  in  the  Executive’s  Base  Salary  (other  than  as  a  result  of  a  broad  based  reduction  of 
salary similarly affecting other Company executives having comparable rank, authority and seniority); or (iv) any material breach 
of this Agreement by the Company; provided that (A) Executive provides Company with written notice that Executive intends to 
terminate Executive’s employment hereunder for one of the grounds set forth in this Section 2(e) within thirty (30) days of such 
ground occurring, (B) if such ground is capable of being cured, the Company has failed to cure such ground within a period of 
thirty  (30)  days  from  the  date  of  such  written  notice,  and  (C)  Executive  terminates  Executive’s  employment  within  sixty-five 
days from the date that Good Reason first occurs.  For purposes of clarification, the above-listed conditions shall apply separately 
to  each  occurrence  of  Good  Reason  and  failure  to  adhere  to  such  conditions  in  the  event  of  Good  Reason  shall  not  disqualify 
Executive from asserting Good Reason for any subsequent occurrence of Good Reason. For purposes of this Agreement, “Good 
Reason” shall be interpreted in a manner, and limited to the extent necessary, so that it shall not cause adverse tax consequences 
for either party with respect to Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”) 
and any successor statute, regulation and guidance thereto.

3.  Compensation.

(a)  Base Salary.  Company shall pay Executive a base salary (the “Base Salary”) at the annual rate of $407,800.  The 
Base Salary shall be payable in substantially equal periodic installments in accordance with Company’s payroll practices as in 
effect  from  time  to  time.    Company  shall  deduct  from  each  such  installment  all  amounts  required  to  be  deducted  or  withheld 
under  applicable  law  or  under  any  employee  benefit  plan  in  which  Executive  participates.  The  Base  Salary  will  be  reviewed 
annually and may be increased.

3

 
 
 
 
 
(b)  Annual Performance Bonus.  Executive shall be eligible to receive an annual cash bonus (the “Annual Performance 
Bonus”), with the target amount of such Annual Performance Bonus equal to forty-five percent (45%) of Executive’s Base Salary 
in the year to which the Annual Performance Bonus relates, provided that the actual amount of the Annual Performance Bonus 
may be greater or less than such target amount.  The Annual Performance Bonus shall be based on both corporate and individual 
performance objectives to be established by the Board of Directors of the Parent Company or an appropriate committee thereof 
by  no  later  than  March  1st  of  the  applicable  bonus  year  (the  “Performance  Objectives”).    Whether  and  to  what  extent  the 
Performance  Objectives  have  been  achieved  and  the  amount  of  any  Annual  Performance  Bonus  payable  hereunder  shall  be 
determined  by  the  Board  of  Directors  of  the  Parent  Company  (or  an  appropriate  committee  thereof)  in  its  sole  and  absolute 
discretion.  Executive must be employed by Company on the date on which the Annual Performance Bonus is paid in order to be 
eligible for, and to be deemed as having earned, such Annual Performance Bonus.  The Company shall deduct from the Annual 
Performance Bonus all amounts required to be deducted or withheld under applicable law or under any employee benefit plan in 
which Executive participates.  

 (c)  Equity.  Executive may be eligible to receive equity awards under the applicable equity incentive plan of the Parent 

Company then in effect, as determined by the Board of Directors of the Parent Company or an appropriate committee thereof.

(d)  Open Time Off.  Executive is eligible to take paid time off for vacation and personal reasons in accordance with 
Company’s Open Time Off policies as in effect from time to time. The guideline for such time off is 3-4 weeks per calendar year. 
This  guideline  excludes  time  off  for  illness,  company-paid  holidays,  year-end  shutdown  and  emergencies.    Time  off  is  to  be 
scheduled  to  minimize  disruption  to  Company’s  operations,  pursuant  to  the  terms  and  conditions  of  Company  Open  Time  Off 
policy and practices as applied to senior executives of the Company.  Time off is not earned or accrued, therefore there are no 
rollover of days from year to year, nor is payment made for unused time off upon separation from employment.

(e)  Fringe Benefits. Executive shall be entitled to participate in all benefit/welfare plans, long-term incentive programs,
and  other  fringe  benefits  provided  to  Company  senior  executives  at  comparable  levels.    The  terms  of  any  such  programs  and 
benefits  will  be  governed  by  the  applicable  plan  documents  and  Company  policies  in  effect  from  time  to  time.    Executive 
understands  that,  except  when  prohibited  by  applicable  law,  Company’s  benefit  plans  and  fringe  benefits  may  be  changed, 
replaced, terminated, modified or amended by Company from time to time in its sole discretion.  

(f)  Reimbursement of Expenses.    Company  shall  reimburse  Executive  for  all  ordinary  and  reasonable  out-of-pocket 
business  expenses  incurred  by  Executive  in  furtherance  of  Company’s  business  in  accordance  with  Company’s  policies  with 
respect thereto as in effect from time to time.  Executive must submit any request for reimbursement no later than thirty (30) days 
following the date that such business expense is incurred. All reimbursements provided under this Agreement shall be made or 
provided  in  accordance  with  the  requirements  of  Section  409A  including,  where  applicable,  the  requirement  that  (i)  any 
reimbursement  is  for  expenses  incurred  during  Executive’s  lifetime  (or  during  a  shorter  period  of  time  specified  in  this 
Agreement); (ii) the amount of expenses eligible for reimbursement during a calendar year may not affect the expenses eligible 
for reimbursement in any other calendar year; (iii) the reimbursement of an eligible expense shall be made no later than the last 
day  of  the  calendar  year  following  the  year  in  which  the  expense  is  incurred;  and  (iv)  the  right  to  reimbursement  or  in  kind 
benefits is not subject to liquidation or exchange for another benefit.

(g) 

Indemnification.  Executive  shall  be  entitled  to  indemnification  with  respect  to  Executive’s  services  provided 
hereunder  pursuant  to  applicable  law,  the  terms  and  conditions  of  Company’s  organizational  and  governing  documents, 
Company’s  directors  and  officers  (“D&O”)  liability  insurance  policy,  and  Company’s  standard  indemnification  agreement  for 
directors and officers as executed by Company and Executive.

4.  Payments Upon Termination.

(a)  Definition of Accrued Obligations.  For purposes of this Agreement, “Accrued Obligations” means: (i) the portion 
of Executive’s Base Salary that has accrued prior to any termination of Executive’s employment with Company and has not yet 
been  paid;  and  (ii)  the  amount  of  any  expenses  properly  incurred  by  Executive  on  behalf  of  Company  prior  to  any  such 
termination and not yet reimbursed.  Executive’s entitlement to any other compensation or benefit under any plan of Company 
shall be governed by and determined in accordance with the terms of such plans, except as otherwise specified in this Agreement.

(b)  Termination by Company for Cause, or by Executive Without Good Reason, or as a Result of Executive’s Disability 
or Death. If Executive’s employment hereunder is terminated by Company for Cause, by Executive without Good Reason, or as a 
result of Executive’s Disability or Death, then Company shall pay the Accrued Obligations to Executive on or before the time 
required by applicable law following the effective date of such termination and shall have no further obligations to Executive.

(c)  Termination  by  Company  Without  Cause  or  by  Executive  For  Good  Reason.    In  the  event  that  Executive’s 
employment is terminated by Company without Cause or Executive terminates Executive’s employment for Good Reason, then, 
in addition to the Accrued Obligations, Executive shall receive the following, subject to the terms and conditions described in 
Section 4(e) (including Executive’s execution of a release of claims):

(i)  Severance Payments.  Continuation of payments in an amount equal to (x) Executive’s then-current Base 
Salary for a period of twelve (12) months, and (y) an amount equal to the target Annual Performance Bonus to which 
Executive  may  have  been  entitled  for  the  year  in  which  Executive’s  employment  terminates,  prorated  to  reflect  that 
portion  of  the  year  in  which  Executive  was  employed,  less  all  customary  and  required  taxes  and  employment-related 
deductions, which amounts  shall  be  paid  over  time  in  accordance  with  Company’s normal payroll practices (provided 
such payments shall be made at least monthly), commencing on the first payroll date following the date on which the 
release  of  claims  required  by  Section  4(e)  becomes  effective  and  non-revocable,  but  not  after  seventy  (70)  days 
following  the  effective  date  of  termination  from  employment;  provided,  that  if  the  70th  day  falls  in  the  calendar  year 
following the year during which the termination or separation from service occurred, then the payments will commence 
in such subsequent calendar year; provided further that if such payments commence in such subsequent year, the first 
such  payment  shall  be  a  lump  sum  in  an  amount  equal  to  the  payments  that  would  have  come  due  since  Employee’s 
separation from service.

(ii)  Benefits Payments.  Upon completion of appropriate forms and subject to applicable terms and conditions 
under  the  Consolidated  Omnibus  Budget  Reconciliation  Act  of  1985,  as  amended  (“COBRA”),  the  Company  shall 
continue to pay its share of the costs for Employee’s coverage under the Company’s group health insurance plan, until 
the  earlier  to  occur  of  twelve  (12)  months  following  Executive’s  termination  date  or  the  date  Executive  begins 
employment with another employer; provided that such Company-paid premiums may be recorded as additional income 
pursuant to Section 6041 of the Code and not entitled to any tax qualified treatment to the extent necessary to comply 
with or avoid the discriminatory treatment prohibited by the Patient Protection and Affordable Care Act of 2010 and the 
Health  Care  and  Education  Reconciliation  Act  of  2010  or  Section  105(h)  of  the  Code.  Executive  shall  bear  full 
responsibility  for  applying  for  COBRA  continuation  coverage  and  Company  shall  have  no  obligation  to  provide 
Executive such coverage if Executive fails to elect COBRA benefits in a timely fashion.

Payment  of  the  above  described  severance  payments  and  benefits  are  expressly  conditioned  on  Executive’s  execution 
without revocation of the release of claims under Section 4(e) and return of Company property under Section 6.  In the event that 
Executive is eligible for the severance payments and benefits under 

5

 
 
this Section 4(c), Executive shall not be eligible for and shall not receive any of the severance payments and benefits as provided 
in Section 4(d).

(d)  Termination by Company Without Cause or by Executive For Good Reason Following a Change of Control.  In the 
event that a Change of Control (as defined below) occurs and within a period of one (1) year following the Change of Control, 
either Executive’s employment is terminated by Company without Cause, or Executive terminates Executive’s employment for 
Good  Reason,  then,  in  addition  to  the  Accrued  Obligations,  Executive  shall  receive  the  following,  subject  to  the  terms  and 
conditions described in Section 4(e) (including Executive’s execution of a release of claims):

(i)  Lump  Sum  Severance  Payment.  Payment  of  a  lump  sum  amount  equal  to  twelve  (12)  months  of 
Executive’s then-current Base Salary, less all customary and required taxes and employment-related deductions, paid on 
the first payroll date following the date on which the release of claims required by Section 4(e) becomes effective and 
non-revocable, but not after seventy (70) days following the effective date of termination from employment.

(ii)  Separation Bonus.  Payment of a separation bonus in an amount equal to the target Annual Performance 
Bonus  to  which  Executive  may  have  been  entitled  for  the  year  in  which  Executive’s  employment  terminates  less  all 
customary  and  required  taxes  and  employment-related  deductions,  paid  on  the  first  payroll  date  following  the  date  on 
which  the  release  of  claims  required  by  Section  4(e)  becomes  effective  and  non-revocable,  but  not  after  seventy  (70) 
days following the effective date of termination from employment. 

(iii)  Benefit Payments.  Upon completion of appropriate forms and subject to applicable terms and conditions 
under  the  COBRA,  the  Company  shall  continue  to  pay  its  share  of  the  costs  for  Employee’s  coverage  under  the 
Company’s  group  health  insurance  plan,  until  the  earlier  to  occur  of  twelve  (12)  months  following  Executive’s 
termination  date  or  the  date  Executive  begins  employment  with  another  employer;  provided  that  such  Company-paid 
premiums  may  be  recorded  as  additional  income  pursuant  to  Section  6041  of  the  Code  and  not  entitled  to  any  tax 
qualified treatment to the extent necessary to comply with or avoid the discriminatory treatment prohibited by the Patient 
Protection and Affordable Care Act of 2010 and the Health Care and Education Reconciliation Act of 2010 or Section 
105(h)  of  the  Code.    Executive  shall  bear  full  responsibility  for  applying  for  COBRA  continuation  coverage  and 
Company shall have no obligation to provide Executive such coverage if Executive fails to elect COBRA benefits in a 
timely fashion.

Payment  of  the  above  described  severance  payments  and  benefits  are  expressly  conditioned  on  Executive’s  execution 
without revocation of the release of claims under Section 4(e) and return of Company property under Section 6.  In the event that 
Executive is eligible for the severance payments and benefits under this Section 4(d), Executive shall not be eligible for and shall 
not receive any of the severance payments and benefits as provided in Section 4(c).

As used herein, a “Change of Control” shall mean (A) a merger or consolidation of the Parent Company whether or not 
approved by the Board of Directors, other than a merger or consolidation which would result in the voting securities of the Parent 
Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted 
into  voting  securities  of  the  surviving  entity  or  the  parent  of  such  corporation)  more  than  50%  of  the  total  voting  power 
represented by the voting securities of the Parent Company or such surviving entity or parent of such corporation, as the case may 
be, outstanding immediately after such merger or consolidation; or (B) the sale or disposition by the Parent Company of all or 
substantially  all  of  the  Parent  Company’s  assets  in  a  transaction  requiring  shareholder  approval;  or  (C)  the  transfer,  sale  or 
disposition by the Parent Company of 50% or more of its interest in Company.  

6

 
(e)  Execution of Release of Claims. Company shall not be obligated to pay Executive any of the severance payments or 
benefits described in this Section 4 unless and until Executive has executed (without revocation) a timely release of claims in a 
form acceptable to Company, which shall include a general release of claims against Company and Parent Company (including 
its  and  their  affiliated  entities,  and  its  and  their  officers,  directors,  employees  and  others  associated  with  such  entities),  a 
reaffirmation  of  Executive’s  covenants  under  the  terms  of  the  Agreement  to  Protect  Confidential  Information,  Inventions  and 
Business  (as  referenced  in  Section  5  below),  as  well  as  standard  and  reasonable  terms  regarding  items  such  as  mutual  non-
disparagement, confidentiality, cooperation and the like (the “Release Agreement”).  The Release Agreement must be provided to 
Executive  within  fifteen  (15)  days  following  Executive’s  separation  from  service,  and  signed  by  Executive  and  returned  to 
Company no later than sixty (60) days following Executive’s separation from service (the “Review Period”).  If Executive fails or 
refuses to return the Release Agreement within the Review Period, Executive’s severance payments and benefits hereunder shall 
be forfeited.

(f)  No  Other  Payments  or  Benefits  Owing.  The  payments  and  benefits  set  forth  in  this  Section  4  shall  be  the  sole 
amounts owing to Executive upon termination of Executive’s employment for the reasons set forth above and Executive shall not 
be eligible for any other payments or other forms of compensation or benefits. The payments and benefits set forth in Section 4
shall be the sole remedy, if any, available to Executive in the event that Executive brings any claim against Company relating to 
the termination of Executive’s employment under this Agreement.

5.  Prohibited Competition, Solicitation, and Non-Disclosure. 

(a)  Executive expressly acknowledges that: (i) there are competitive and proprietary aspects of the business of Company  
and its affiliates; (ii) during the course of Executive’s employment, Company and/or its affiliates shall furnish, disclose or make 
available to Executive confidential and proprietary information and may provide Executive with unique and specialized training; 
(iii)  such  Confidential  Information  and  training  have  been  developed  and  shall  be  developed  by  Company  and/or  its  affiliates 
through the expenditure of substantial time, effort and money, and could be used by Executive to compete with Company and/or 
its  affiliates;  and  (iv)  in  the  course  of  Executive’s  employment,  Executive  shall  be  introduced  to  customers  and  others  with 
important relationships to Company and/or its affiliates, and any and all “goodwill” created through such introductions belongs 
exclusively  to  Company  and  its  affiliates,  including,  but  not  limited  to,  any  goodwill  created  as  a  result  of  direct  or  indirect 
contacts  or  relationships  between  Executive  and  any  customers  of  Company  and  its  affiliates.    In  light  of  the  foregoing 
acknowledgements, Executive hereby (x) acknowledges that Executive previously executed and agrees to abide by the terms and 
conditions set forth in the Company’s Agreement to Protect Confidential Information, Inventions and Business (attached hereto 
as Exhibit A) and the Company’s Confidentiality and Information Systems Usage Agreement (attached hereto as Exhibit B), (y) 
reaffirms  Executive’s  obligations  under  the  terms  of  the  previously  executed  Agreement  to  Protect  Confidential  Information, 
Inventions and Business and Confidentiality and Information Systems Usage Agreement, and (z) acknowledges and agrees that 
nothing  herein  shall  impact  or  affect  the  continued  validity  of  the  previously  executed  Agreement  to  Protect  Confidential 
Information, Inventions and Business and Confidentiality and Information Systems Usage Agreement.  

(b)  Executive hereby acknowledges and agrees that in consideration for Executive’s non-competition covenant as set forth 
in  Agreement  to  Protect  Confidential  Information,  Inventions  and  Business,  the  Company  is  providing  the  Executive  with 
eligibility to receive the certaion severance payments and benefits under the conditions set forth in Section 4 hereof.  Executive 
further acknowledges and agrees that the aforementioned 

7

 
 
 
 
 
 
 
 
consideration is fair and reasonable consideration independent of the Executive’s employment with the Company for purposes of 
Executive’s non-competition covenant.

(c)  Executive hereby expressly acknowledges and agrees that if Executive breaches any of the terms and/or conditions set 
forth  in  the  Agreement  to  Protect  Confidential  Information,  Inventions  and  Business  following  a  termination  of  Executive’s 
employment either by Company without Cause or by Executive for Good Reason, then, in addition to the relief described in the 
Agreement to Protect Confidential Information, Inventions and Business, (i) Company shall cease providing the Executive with 
any further payments under Section 4(c) or 4(d) (as applicable) as of the date of such breach, (ii) Company shall not be obligated 
to provide Executive with, and Executive shall not be eligible or otherwise entitled to receive, any further payments or benefits 
from  Company,  (iii)  Company’s  obligation  to  provide  Executive  with  any  further  such  payments  or  benefits  shall  be  null  and 
void, and of no further force or effect, and (iv) Company shall be entitled to recover, and Executive shall be obligated to repay to 
Company, any payments and the value of any benefits previously provided to Executive by Company under Section 4(c) or 4(d) 
(as  applicable)  prior  to  the  date  of  Executive’s  breach  of  the  Agreement  to  Protect  Confidential  Information,  Inventions  and 
Business.

6.  Property and Records. Upon the termination of Executive’s employment hereunder for any reason or for no reason, or 
if  Company  otherwise  requests,  Executive  shall:  (a)  return  to  Company  all  tangible  business  information  and  copies  thereof 
(regardless how such Confidential Information or copies are maintained), and (b) deliver to Company any property of Company 
which  may  be  in  Executive’s  possession,  including,  but  not  limited  to,  Blackberry-type  devices,  smart  phones,  laptops,  cell 
phones, products, materials, memoranda, notes, records, reports or other documents or photocopies of the same.

7.  Code Sections 409A and 280G.   

(a)  In the event that the payments or benefits set forth in Section 4 of this Agreement constitute “non-qualified deferred  

compensation” subject to Section 409A, then the following conditions apply to such payments or benefits:

(i)  Any  termination  of  Executive’s  employment  triggering  payment  of  benefits  under  Section  4  must  
constitute a “separation from service” under Section 409A(a)(2)(A)(i) of the Code and Treas. Reg. §1.409A-1(h) before 
distribution  of  such  benefits  can  commence.    To  the  extent  that  the  termination  of  Executive’s  employment  does  not 
constitute a separation of service under Section 409A(a)(2)(A)(i) of the Code and Treas. Reg. §1.409A-1(h) (as the result 
of  further  services  that  are  reasonably  anticipated  to  be  provided  by  Executive  to  Company  at  the  time  Executive’s 
employment terminates), any such payments under Section 4 that constitute deferred compensation under Section 409A 
shall be delayed until after the date of a subsequent event constituting a separation of service under Section 409A(a)(2)
(A)(i)  of  the  Code  and  Treas.  Reg.  §1.409A-1(h).    For  purposes  of  clarification,  this  Section  7(a)  shall  not  cause  any 
forfeiture  of  benefits  on  Executive’s  part,  but  shall  only  act  as  a  delay  until  such  time  as  a  “separation  from  service” 
occurs.  

(ii)  Notwithstanding any other provision with respect to the timing of payments under Section 4 if, at the time 
of Executive’s termination, Executive is deemed to be a “specified employee” (within the meaning of Section 409A(a)
(2)(B)(i) of the Code), then limited only to the extent necessary to comply with the requirements of Section 409A, any 
payments  to  which  Executive  may  become  entitled  under  Section  4  which  are  subject  to  Section  409A  (and  not 
otherwise  exempt  from  its  application)  shall  be  withheld  until  the  first  (1st)  business  day  of  the  seventh  (7th)  month 
following the termination of Executive’s employment, at which time Executive shall be paid an aggregate amount equal 
to the accumulated, but unpaid, payments otherwise due to Executive under the terms of Section 4.

(b)  It is intended that each installment of the payments and benefits provided under Section 4 of this Agreement shall be  
treated as a separate “payment” for purposes of Section 409A.  Neither Company nor Executive shall have the right to accelerate 
or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A. 

(c)  Notwithstanding any other provision of this Agreement to the contrary, this Agreement shall be interpreted and at 
all times administered in a manner that avoids the inclusion of compensation in income under Section 409A, or the payment of 
increased taxes, excise taxes or other penalties under Section 409A. The parties intend this Agreement to be in compliance with 
Section  409A.    Executive  acknowledges  and  agrees  that  Company  does  not  guarantee  the  tax  treatment  or  tax  consequences 
associated with any payment or benefit arising under this Agreement, including but not limited to consequences related to Section 
409A. 

(d)  If any payment or benefit Executive would receive under this Agreement, when combined with any other payment or  
benefit  Executive  receives  pursuant  to  a  Change  of  Control  (for  purposes  of  this  section,  a  “Payment”)  would:  (i)  constitute  a 
“parachute payment” within the meaning of Section 280G the Code; and (ii) but for this sentence, be subject to the excise tax 
imposed  by  Section  4999  of  the  Code  (the  “Excise  Tax”),  then  such  Payment  shall  be  either:  (A)  the  full  amount  of  such 
Payment; or (B) such lesser amount (with cash payments being reduced before stock option compensation) as would result in no 
portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable 
federal, state and local employments taxes, income taxes, and the Excise Tax, results in Executive’s receipt, on an after-tax basis, 
of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax.

8.  General.

(a)  Notices.  Except as otherwise specifically provided herein, any notice required or permitted by this Agreement shall 
be in writing and shall be delivered as follows with notice deemed given as indicated: (i) by personal delivery when delivered 
personally;  (ii)  by  overnight  courier  upon  written  verification  of  receipt;  (iii)  by  telecopy  or  facsimile  transmission  upon 
acknowledgment  of  receipt  of  electronic  transmission;  or  (iv)  by  certified  or  registered  mail,  return  receipt  requested,  upon 
verification of receipt.

may specify in writing.
