RISK FACTOR SUMMARY

The below summary risk factors provide an overview of certain of the risks we are exposed to in the normal course of

our business activities. The below summary risk factors do not contain all of the information that may be important to
investors, and investors should read the summary risk factors together with the more detailed discussion of risks set forth
in Part I, Item 1A, “Risk Factors,” of this Annual Report.

● We have a history of significant operating losses and expect to incur significant and increasing losses for the

foreseeable future, and we may never achieve or maintain profitability.

● We may need substantial additional funding, and if we are unable to raise capital when needed, we could be
forced to delay, reduce or eliminate our product discovery and development programs or commercialization
efforts.

● Raising additional capital may cause dilution to our existing shareholders or holders of our American

Depositary Shares, or ADSs, restrict our operations or cause us to relinquish valuable rights.

● Our failure to comply with the covenants or payment obligations under our existing term loan facility with

Hercules Capital, Inc., or Hercules, could result in an event of default, which may result in increased interest
charges, acceleration of our repayment obligations or other actions by Hercules, any of which could
negatively impact our business, financial condition and results of operations.

● We are at a very early stage in our development efforts, our product candidates and those of our collaborators
represent a new category of medicines and may be subject to heightened regulatory scrutiny until they are
established as a therapeutic modality.

● We are substantially dependent on the success of our internal development programs and of our product

candidates from our Bicycle Toxin Conjugates, or BTCs, Bicycle tumor-targeted immune cell agonist™, or
TICA™, programs, which may not successfully complete clinical trials, receive regulatory approval or be
successfully commercialized.

● We may find it difficult to enroll patients in our clinical trials, which could delay or prevent us from

proceeding with clinical trials of our product candidates.

● Results of preclinical studies and early clinical trials may not be predictive of results of future clinical trials.
● Our current or future product candidates may cause undesirable side effects or have other properties when

used alone or in combination with other approved products or investigational new drugs, or IND, that could
halt their clinical development, prevent their marketing approval, limit their commercial potential or result in
significant negative consequences.

● We may be delayed or not be successful in our efforts to identify or discover additional product candidates.
● 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.

● We may seek designations for our product candidates with the U.S. Food and Drug Administration, or FDA, 
and other comparable regulatory authorities that are intended to confer benefits such as a faster development 
process or an accelerated regulatory pathway, but there can be no assurance that we will successfully obtain 
such designations.  In addition, even if one or more of our product candidates are granted such designations, 
we may not be able to realize the intended benefits of such designations.

● Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is 

expensive, time consuming and uncertain and may prevent us or any collaborators from obtaining approvals 
for the commercialization of some or all of our product candidates.  As a result, we cannot predict when or if, 
and in which territories, we, or any collaborators, will obtain marketing approval to commercialize a product 
candidate.

iii

Table of Contents

● The market opportunities for any current or future product candidate we develop, if and when approved may
be limited to those patients who are ineligible for established therapies or for whom prior therapies have
failed, and may be small.

● We face significant competition and if our competitors develop and market products that are more effective,
safer or less expensive than the product candidates we develop, our commercial opportunities will be
negatively impacted.

● Even if we receive marketing approval of a product candidate, we will be subject to ongoing regulatory

obligations and continued regulatory review, which may result in significant additional expense and we may
be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated
problems with our products, if approved.

● The commercial success of any current or future product candidate will depend upon the degree of market

acceptance by physicians, patients, payors and others in the medical community.

● The insurance coverage and reimbursement status of newly-approved products is uncertain.  Failure to obtain 
or maintain adequate coverage and reimbursement for any of our product candidates, could limit our ability to 
market those products and decrease our ability to generate revenue.

● Healthcare legislative reform measures may have a negative impact on our business and results of operations.
● We rely on third parties, including independent clinical investigators and clinical research organizations, or 
CROs, to conduct and sponsor some of the clinical trials of our product candidates.  Any failure by a third 
party to meet its obligations with respect to the clinical development of our product candidates may delay or 
impair our ability to obtain regulatory approval for our product candidates.

● We intend to rely on third parties to manufacture product candidates, which increases the risk that we will not
have sufficient quantities of such product candidates or products or such quantities at an acceptable cost,
which could delay, prevent or impair our development or commercialization efforts.

● If we are unable to obtain and maintain patent and other intellectual property protection for our products and
product candidates, or if the scope of the patent and other intellectual property protection obtained is not
sufficiently broad, our competitors could develop and commercialize products similar or identical to ours, and
our ability to successfully commercialize our products and product candidates may be adversely affected.
● If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and
time consuming and could prevent or delay us from developing or commercializing our product candidates

● As a company based outside of the United States, we are subject to economic, political, regulatory and other

risks associated with international operations.

● COVID-19 could impact our business.
● The market price of our ADSs is highly volatile, and holders of our ADSs may not be able to resell their

ADSs at or above the price at which they purchased their ADSs.

ITEM 1.       BUSINESS.

PART I

We are a clinical-stage biopharmaceutical company developing a novel class of medicines, which we refer to as
Bicycles, for diseases that are underserved by existing therapeutics. Bicycles are fully synthetic short peptides constrained
to form two loops which stabilize their structural geometry. This constraint facilitates target binding with high affinity and
selectivity, making Bicycles attractive candidates for drug development. Bicycles are a unique therapeutic modality
combining the pharmacology usually associated with a biologic with the manufacturing and pharmacokinetic, or PK,
properties of a small molecule. The relatively large surface area presented by Bicycles allow targets to be drugged that have
historically been intractable to non-biological approaches. Bicycles are excreted by the kidney rather than the liver and
have shown no signs of immunogenicity to date, which we believe together support a favorable toxicological profile.

We have a novel and proprietary phage display screening platform which we use to identify Bicycles in an

efficient manner. The platform initially displays linear peptides on the surface of engineered bacteriophages, or phages,
before “on-phage” cyclization with a range of small molecule scaffolds which can confer differentiated physicochemical
and structural properties. Our platform encodes quadrillions of potential Bicycles which can be screened to identify
molecules for optimization to potential product candidates. We have used this powerful screening technology to identify
our current portfolio of candidates in oncology and intend to use it in conjunction with our collaborators to seek to develop
additional future candidates across a range of other disease areas.

Our initial internal programs are focused on oncology indications with high unmet medical need. Our lead product

candidates, BT1718, BT5528 and BT8009, are Bicycle Toxin Conjugates®, or BTCs. These Bicycles are chemically
attached to a toxin that when administered is cleaved from the Bicycle® and kills the tumor cells. BT1718 targets tumors 
that express Membrane Type 1 matrix metalloproteinase, or MT1-MMP, and is currently in an ongoing Phase I/IIa clinical 
trial in collaboration with, and fully funded by, the Cancer Research UK Centre for Drug Development, or Cancer Research 
UK, to evaluate its safety, tolerability and efficacy. We are also evaluating BT5528, a second-generation BTC targeting 
Ephrin type A receptor 2, or EphA2, in a company-sponsored Phase I/II clinical trial as a monotherapy and in combination 
with nivolumab, and BT8009, a second-generation BTC targeting Nectin-4, in a company-sponsored Phase I/II clinical 
trial.  Our discovery pipeline in oncology includes Bicycle-based systemic immune cell agonists and Bicycle tumor-
targeted immune cell agonists, or TICAs.

Beyond our wholly-owned oncology portfolio, we are collaborating with biopharmaceutical companies and

organizations in therapeutic areas in which we believe our proprietary Bicycle screening platform can identify therapies to
treat diseases with significant unmet medical need. Our partnered programs outside of oncology include

2

Table of Contents

collaborations in immuno-oncology, or I-O, anti-infective, cardiovascular, ophthalmology, dementia and respiratory
indications.

The following table summarizes key information about our programs:

We were founded in 2009 based on innovative science conducted by Sir Greg Winter and Professor Christian

Heinis. Sir Greg Winter is a pioneer in monoclonal antibodies and, in 2018, was awarded a Nobel Prize in chemistry for the
invention of the technology underpinning our proprietary phage display screening platform that we use to identify Bicycles.
From our founding through December 31, 2020, we have generated substantial intellectual property, including four patent
families directed to novel scaffolds, 16 patent families directed to our platform technology, 79 patent families directed to
bicyclic peptides and related conjugates, and nine patent families directed to clinical indications and other properties of
development assets. The work we have conducted in developing Bicycles and our proprietary screening platform have
created substantial know-how that we believe provides us with a competitive advantage.

Our management team includes veterans in drug development with executive experience at leading
biopharmaceutical companies including Amgen, GlaxoSmithKline, Novartis and Pfizer. Our board of directors and
scientific advisory board include industry experts and seasoned investors, with extensive experience in I-O.

Our Strategy

Our mission is to become a leading biopharmaceutical company by pioneering Bicycles as a novel therapeutic

modality to treat diseases that are inadequately addressed with existing treatment modalities. Specifically, we seek to
execute on the following strategy to maximize the value of our novel technology and pipeline:

● Progress our most advanced candidates, BT1718, BT5528 and BT8009, through clinical development. 
 BT1718 is being investigated in an ongoing Phase I/IIa clinical trial sponsored by Cancer Research UK.
Cancer Research UK initiated expansion cohorts in the Phase IIa portion of the Phase I/IIa study in 2020. We
are also evaluating BT5528, a second-generation BTC targeting EphA2, in a company-sponsored Phase I/II
clinical trial as a monotherapy and in combination with nivolumab, and BT8009, a second-generation BTC
targeting Nectin-4, in a company-sponsored Phase I/II clinical trial. We intend to advance development of
these candidates across oncology indications based on target expression.

● Continue IND-enabling activities for our lead TICA program, BT7480. BT7480 is a fully synthetic TICA

that contains a Bicycle targeting Nectin-4 and a Bicycle targeting the costimulatory receptor CD137. BT7480
has been shown in preclinical models to rapidly penetrate tumors, have anti-tumor activity, and induce
immune memory specific to the implanted tumor. IND-enabling activities for BT7480 are ongoing, and we
are on track to commence the Phase I clinical trial in the second half of 2021. 

● Pursue clinical development of our discovery programs.  We intend to continue our ongoing discovery
activities to screen and select promising candidates for oncology indications. For example, early I-O

3

Table of Contents

discovery efforts have resulted in the identification of TICA candidates targeting natural killer, or NK, cells.
We are currently advancing these programs into lead optimization.

● Leverage our powerful proprietary screening platform and novel Bicycle modality to grow our pipeline. 
 Our novel and proprietary phage display screening platform allows us to rapidly and efficiently identify
potential candidates for development. We can incorporate a wide range of small molecule scaffolds into
Bicycles to increase diversity and confer differentiated physicochemical and structural properties. We have
used our powerful Bicycle screening platform to identify our current pipeline of promising BTCs and TICAs,
and we intend to use it to develop a broader pipeline of diverse product candidates.

● Collaborate strategically with leading organizations to access enabling technology and expertise in order

to expand the application of our novel Bicycle modality to indications beyond oncology.  We are
collaborating with leading biopharmaceutical companies and organizations to apply our novel Bicycle
modality to other disease areas, including, anti-infective, cardiovascular, ophthalmology, dementia and
respiratory indications. We may opportunistically enter into additional collaborations in the future to apply
our technology to areas of unmet medical need.

● If approved, maximize the commercial potential of our product candidates by either establishing our own 
sales and marketing infrastructure or doing so through collaborations with others.  Subject to receiving
marketing approval, we intend to pursue the commercialization of our product candidates either by building
internal sales and marketing capabilities or doing so through opportunistic collaborations with others.

The Bicycle Opportunity

Introduction to Bicycles

Bicycles are fully synthetic, short peptides consisting of nine to 20 amino acids constrained to form two loops

which stabilize the structural geometry of the peptide and facilitate target binding with high affinity and selectivity.
Bicycles represent a unique therapeutic class, combining the pharmacological properties normally associated with a
biologic with the manufacturing and PK advantages of a small molecule, with no signs of immunogenicity observed to
date.

Drugs must bind to target proteins with high affinity and selectivity to achieve a therapeutic effect, while

minimizing undesired effects on other proteins and physiological functions. Peptides exist in a number of folded states,
only a few of which are able to bind to target proteins, and a key challenge for peptide therapeutics is designing structures
that achieve these goals. We have designed our molecules to be highly constrained by linking a chemical connector
compound, also known as a scaffold, to particular amino acids in the peptide chain. The resulting cyclized molecule, which
we refer to as a Bicycle, is locked in the preferred state to bind to the target proteins.

Schematic of the Creation of a Cyclized Molecule Resulting in a Bicycle

4

Table of Contents

We have expanded the diversity of the chemical space we can cover from approximately 1013 potential molecules

in 2009 to 1020 today. We have applied our novel Bicycle modality to a growing range of targets, from a single target in
2009 to more than 125 today. We can create a wide range of Bicycles by varying four parameters:

● the number of amino acids in the two loops;

● the amino acid composition at each position;

● the symmetry of the two loops; and

● the small molecule scaffold used to cyclize the Bicycle.

Properties of Bicycles as Therapeutic Agents

Bicycles have a large surface area available for target binding, which is designed to allow for high affinity and
selectivity to the designated target. As short sequences of amino acids, or peptides, they have a low molecular weight,
typically ranging from 1.5 kDa to 2.0 kDa. Bicycles have a readily adjustable PK profile with good plasma stability and
rapid distribution from the vasculature into the extracellular space. This PK profile enables rapid tissue penetration and a
renal route of elimination that minimizes liver exposure. Toxicity issues are observed with small molecules that are
metabolized and eliminated by the liver. Bicycle peptides, by contrast, are not subject to metabolism or elimination by the 
liver but are metabolized in the peripheral circulation or kidney with subsequent rapid excretion in the urine.  
Consequently, by increasing excretion in urine, the liver exposure is minimized and the risk of liver toxicity is reduced. The 
modular nature of Bicycles allows us to optimize therapeutic molecules for specific targets. To date, we have observed no
signs of immunogenicity.

Compared to biologics, Bicycles have a lower cost of production and a simpler manufacturing process, and are
recognized by regulatory authorities as small molecule new chemical entities. We can readily identify Bicycles that may
drug a wide spectrum of targets and target classes, including many that have so far been undruggable with small molecules,
such as protein-protein interactions. Our novel and proprietary screening platform allows us to screen Bicycles against
molecular targets rapidly and efficiently, affording potentially reduced timelines and costs compared to other high-
throughput screening approaches. Leveraging our platform, we can rapidly and efficiently identify a compound for
development in as few as six months with the historical average time being 12 months after a target has been selected.

Comparison of Bicycles to Other Common Classes of Therapeutics

Our Proprietary Bicycle Screening Platform

We utilize our novel and proprietary phage display screening platform to identify Bicycles that are potentially
useful in medicine. We have used this technology to identify our current pipeline and intend to leverage it to develop a
broader portfolio of product candidates to address unmet medical needs across a wide range of diseases.

Phages are bacteria-infecting viruses consisting of genetic material wrapped in a protein coat. Phages can be

harnessed to identify Bicycles by splicing DNA into the genome of a phage so that the linear peptides that encode Bicycles
are presented on the surface of the phage. Our founder Sir Greg Winter, a pioneer in phage display, applied this

6

Table of Contents

technology and added a cyclization step that forms Bicycles from these linear peptides. This technology underpins our
novel and proprietary screening platform.

Our screening process self-selects for Bicycles that are amenable to attachment, commonly referred to as

conjugation, to other molecular payloads such as cytotoxins, innate immune agonists or other Bicycles. Bicycles can be
linked together with synthetic ease to create complex molecules with combinatorial pharmacology. Alternatively, Bicycles
in the form of multimers can also be used as standalone therapeutics, such as those that we are exploring in our systemic
and tumor-targeted immune cell agonist programs. We believe that the flexibility of our Bicycles and our powerful
screening platform allow new therapeutics to be rapidly conceived and reduced to practice to potentially serve diverse
therapeutic applications across a wide range of indications. We can readily identify Bicycles that may drug a wide spectrum
of targets and target classes, including many that have so far been undruggable with small molecules, such as protein-
protein interactions.

Schematic of our Proprietary Bicycle Screening Process

We have optimized our proprietary Bicycle screening platform, enabling the technique to be applied to a diverse

range of over 125 challenging targets to date, successfully identifying Bicycles for over 80% of these targets, some of
which are intractable to small molecules. During these screens, Bicycles with diverse pharmacologies were identified,
including enzyme inhibitors, receptor antagonists, agonists (partial, full and supra) and neutral site binders. Neutral site
binders often bind to entirely novel sites on target proteins, previously undescribed in the scientific literature. These binders
can be useful when conjugated with therapeutic payloads since they allow antigen-targeted payload delivery without
impacting target function.

Our Product Candidates

Our portfolio of internal product candidates is directed to oncology applications where we believe they have the

potential to treat a broad spectrum of cancers. We are collaborating with biopharmaceutical companies and organizations in
other therapeutic areas, where we believe our proprietary Bicycle screening platform can identify therapies to treat diseases
with significant unmet medical need.

Table of Contents

Our Pipeline

The following table summarizes key information about our pipeline programs.

Our Oncology Programs

We believe Bicycles are an ideal vehicle to deliver small molecule payloads to tumors, both as potent cytotoxins in
the case of BTCs, as well as small molecule agonists of the immune system in the case of our Bicycle-targeted immune cell
agonists. We believe that Bicycle conjugates can offer improved performance as compared to antibody-mediated delivery.

In addition to their use as drug conjugates, Bicycles can also be configured for use as standalone therapeutics. We

have identified Bicycles that have been observed to directly interact with CD137, a key immune cell co-stimulatory
molecule. We believe our CD137-targeting Bicycles may overcome limitations inherent in antibody-mediated approaches
and have the potential to be converted into simple tumor-targeted immune cell-engaging Bicycle molecules.

Bicycle Toxin Conjugates

Within our BTC programs, we are developing BT1718 (carrying a DM1 (mertansine) cytotoxin payload), which is

designed to target MT1-MMP expressing tumors. BT1718 is currently being investigated for safety, tolerability and
efficacy in an ongoing Phase I/IIa clinical trial that is being conducted in collaboration with Cancer Research UK Centre
for Drug Development. Patient enrollment in the Phase IIa portion of the Phase I/IIa trial remains ongoing.

We are evaluating BT5528, our first second-generation BTC that targets EphA2 and carries a monomethyl

auristatin E, or MMAE, cytotoxin payload, in an ongoing, company-sponsored Phase I/II clinical trial to assess safety,
pharmacokinetics, and preliminary clinical activity in patients with solid tumors. We are currently enrolling patients in the
Phase I portion of the Phase I/II trial of BT5528.

We are also evaluating BT8009, a second-generation BTC that targets Nectin-4 and carries an MMAE cytotoxin

payload, in an ongoing company-sponsored Phase I/II clinical trial to assess to assess the safety,

8

Table of Contents

pharmacokinetics, and preliminary clinical activity in patients with Nectin-4 expressing advanced malignancies.  Studies 
have demonstrated that MT1-MMP, EphA2 and Nectin-4 are overexpressed in many cancer types with high unmet medical 
needs, including lung cancer, breast, gastric, endometrial, sarcoma, pancreatic, bladder, ovarian, esophageal and other 
cancers. Studies have also shown that tumor overexpression in each of these targets has been associated with poor 
prognosis in specific cancers. We therefore believe our BTC candidates may address a wide range of cancer types with 
significant unmet medical need.

Background

The discovery of monoclonal antibodies enabled the development of antibody drug conjugates, or ADCs. ADCs
link antibodies that target tumor-associated antigens to potent cytotoxins through a process known as conjugation. ADCs
are designed to selectively and potently destroy cancer cells by combining the targeting capability of antibodies with the
cancer-killing ability of cytotoxins. Despite the growing use of ADCs in treating cancer and high interest in ADC
development programs, we believe there are significant challenges to ADCs. The large molecular size of the antibody
impairs the penetration of ADCs into tumors. ADCs are generally required to internalize into tumor cells after binding to
internalizing tumor antigens to the surface. Finally, the relatively long systemic exposure and subsequent liver clearance
generally associated with ADCs result in dose-limiting toxicities such as hematological, liver and gastrointestinal toxicities,
and neuropathies.

Properties of  Bicycle Toxin Conjugates

We believe the properties of our BTCs may address the challenges associated with ADCs and therefore that our

approach has the potential to offer substantial benefits, including:

● Extensive and rapid tumor penetration. Bicycles have been observed in our preclinical studies to penetrate
tumors more rapidly and exhibited increased penetration to poorly perfused regions of the tumor when
compared to a comparator antibody. Early clinical data from an ongoing clinical trial has shown ten times
higher tumor cytotoxin levels than corresponding plasma levels based on clinical tumor biopsies taken 24
hours post-infusion.

● Retention in tumors.  In preclinical studies a tumor antigen targeting Bicycle was observed to be retained in
the tumor for at least 120 hours after dosing. Preliminary clinical data observed to date from our ongoing
clinical trials are consistent with preclinical observations of post-dose tumor retention.

● Short systemic half-life and renal elimination. Bicycles have been observed in clinical and preclinical

studies to have a short systemic half-life of approximately 20 to 30 minutes. Due to their small size, Bicycles
are able to exit the tissue rapidly and are excreted through the kidneys rather than the liver, which we expect
will support a favorable toxicity profile.

● No requirement for internalization.  Unlike ADCs, which require cellular internalization for activity, BTCs
do not require internalization into the cell, and therefore potentially can target a wider range of tumor
antigens.

● Access to non-expressing tumor cells.  The toxin in our BTCs is liberated in the extracellular space, enabling
cell-killing adjacent cells that do not express the specific target through a toxin bystander effect. In our
preclinical studies, we observed activity for BTCs even in tumors that were heterogeneous for target
expression.

● Larger toxin payload.  Despite the small size of Bicycles, they are able to carry a larger dose of toxin per unit
mass than a comparator ADC. Therefore, we believe that Bicycles can deliver a higher concentration of the
linked toxin to increase the probability of tumor killing.

● Manufacturing.  The fully synthetic process by which Bicycles are manufactured facilitates ease and

consistency of manufacturing and improved formulation compared to ADCs.

In order to compare the ability of a Bicycle conjugate and an antibody conjugate to penetrate a tumor, using

positron emission tomography, or PET, imaging, we compared a radiolabeled Bicycle to an antibody directed at the same
target in a preclinical rodent study. As shown in the figure below, we observed that 15% to 20% of the injected dose per
gram was detected after administration of the Bicycle in the tumor at 40 to 60 minutes, with no antibody detectable in the
tumor during this time. We also observed accumulation of the balance of the Bicycles in the bladder and kidneys, indicating
rapid renal excretion. In contrast, the antibody was detected in the vasculature.

PET Imaging Revealing Payload Delivery in a Mouse Model

In addition, in a preclinical rodent study using photoacoustic imaging, we observed that Bicycles were retained in

the tumor for 24 hours and at levels substantially in excess of those observed with a comparator antibody.

The figure below summarizes the results of a preclinical rodent xenograft model that investigated payload

concentrations over time in different organ systems after administration of a BTC. In this model, we observed the toxin
payload was retained in the target-expressing tumor over time but was rapidly eliminated from other tissues.

Payload Concentrations Over Time in Different Organ Systems After Administration of a BTC

We believe these data demonstrate the potential of BTCs to have long-term sustained activity and to limit the

toxicity that is associated with ADCs.

BT1718

BT1718, is a BTC that we are developing for oncology indications. The molecule is comprised of our MT1-MMP

targeting Bicycle, a hindered disulphide cleavable linker and a DM1 cytotoxin payload.   We are not aware of any other 
cytotoxin conjugates in development that target MT1-MMP.

Schematic of BT1718

MT1-MMP is a matrix metalloprotease involved in tissue remodeling and is generally expressed at relatively low
levels in normal adult tissues. MT1-MMP has an established role in cell invasion and metastasis, and we believe that MT1-
MMP is an attractive target for cytotoxin delivery due to its high level of expression on stromal and tumor cell subsets in
various cancers.

In our preclinical studies, we observed that BT1718 was associated with the greatest anti-tumor effect when
membrane expression of MT1-MMP was high (as quantified by fluorescence activated cell sorting, or FACS). Tumors with
lower levels of expression of MT1-MMP were observed to have reduced levels of response to BT1718. We are

11

Table of Contents

collaborating with leading cancer researchers to determine MT1-MMP expression levels across a panel of tumor types,
which will help inform patient selection for further clinical development. One of the goals of our clinical trials is to better
understand the relationship between the level of target expression and activity of BT1718.

Clinical Development

Ongoing Phase I/IIa First in Human Clinical Trial

BT1718 is being investigated in an ongoing Phase I/IIa open label dose escalation and expansion clinical trial

sponsored by Cancer Research UK. The Phase I part of this trial evaluated up to 40 patients with advanced solid tumors in
two dosing regimens at three sites in the United Kingdom. In the Phase I portion of the Phase I/IIa trial, BT1718 was
generally well-tolerated. Based on the Phase I trial results, 20 mg/m2 of BT1718 administered once weekly was selected as
the Phase IIa dose. This dose is within the efficacious dose range predicted by preclinical models, in which an equivalent
dose level was associated with complete responses, or CRs. With once-weekly dosing, BT1718 appeared tolerable, with
manageable adverse events. Though the primary objective of the Phase I portion of the BT1718 trial was evaluating safety
and tolerability in an unselected group of patients with advanced solid tumors, some signs of anti-tumor activity were
observed: at doses of between 9.6 mg/m2 and 32.0 mg/m2 administered once-weekly, 13 out of 24 response evaluable
patients at the eight week timepoint exhibited best response of at least stable disease. Ten of these 13 patients had a greater
than 10% reduction in at least one target lesion, including a tumor reduction of 68% observed in one patient, a reduction
that meets the RECIST Version 1.1 criteria of a partial response.

The Phase IIa part of the trial, which commenced in 2020, is evaluating BT1718 in patients with tumors that
express MT1-MMP at the recommended Phase II dose of 20 mg/m2, based on the findings from the Phase I part of the trial.  
To determine tumor types of interest, a clinically validated MT1-MMP immunohistochemistry, or IHC, assay, developed in 
collaboration with Cancer Research UK, was used to screen tumor tissue microarrays, or TMA, from multiple tumor types 
selected based on literature reports of high expression of MT1-MMP, including breast, lung, sarcoma, gastric, ovarian, 
endometrial, bladder, and esophageal cancers. To date, the percentage of patients determined to be MT1-MMP-positive at 
the pre-specified cutoff is consistent with previous translational research findings. Enrollment is ongoing at four clinical 
sites, with additional sites expected to begin enrolling patients during the first half of 2021. Patients are currently being 
enrolled into two solid tumor cohorts, one in squamous non-small cell lung cancer, or NSCLC, and the other in an all-
comers “basket” cohort. Depending on results from these first two cohorts, Cancer Research UK may initiate up to two 
additional cohorts. Each cohort will evaluate 16 patients with a specified tumor type determined using the results of the 
MT1-MMP IHC TMA analysis. 

The endpoints for the Phase IIa part of this clinical trial are safety and preliminary efficacy in patients with tumors

expressing MT1-MMP. Archived or fresh tumor samples from all patients are collected and tested for MT1-MMP
expression using the clinically validated IHC and associations with tumor and stromal expression and clinical response will
be explored. Biopsies of tumors will be mandatory in a subset of patients in this part of the trial in order to evaluate tumor
PK and pharmacodynamic biomarkers of response to BT1718.

DM1 delivery has been demonstrated in tumor biopsies at early timepoints (2 out of 3 patients). Concentrations of

DM1 in the clinical tumor biopsy samples are consistent with preclinical data obtained at doses that gave partial (4.2
mg/m2) and full (14.4 mg/m2) tumor regression in mouse xenograft models. In the phase IIa part of the study, additional
tumor biopsies will be taken at later timepoints to further evaluate DM1 retention.

BT5528

BT5528 is a BTC designed to target EphA2. The molecule is comprised of our EphA2 targeting Bicycle, a valine-

citrulline, or val-cit, cleavable linker and a cytotoxin MMAE payload.

Schematic of BT5528

EphA2 is a member of the Ephrin superfamily of receptor tyrosine kinases regulating cell migration, adhesion,

proliferation and differentiation. EphA2 is expressed at relatively low levels in normal adult tissues, but is overexpressed in
numerous difficult to treat tumors including lung, breast, bladder, gastric, ovarian, endometrial, cervical, melanoma,
esophageal, pancreatic, and glioma. In both cell-derived and patient-derived preclinical models, we observed anti-tumor
activity signals following administration of our EphA2 toxin conjugates, which correlated with EphA2 expression, as
determined by FACS studies.

13

Table of Contents

Effect of EphA2 Expression on BT5528 Activity Across Preclinical Xenograft Models

EphA2 has previously been pursued by other companies utilizing antibody drug conjugates, or ADCs. However,

significant safety concerns, including bleeding events and liver toxicity, were observed in preclinical studies and early
clinical development, which resulted in the discontinuation of development. For example, in a Phase I clinical trial of
MEDI-547, an EphA2-targeting ADC, an increase in the liver enzyme ALT and AST was observed in half of the dosed
patients and bleeding events were observed in five out of six patients, in each case within two to eight days following a
single dose. The bleeding events observed in humans from the clinical trial were consistent with findings from the
preclinical studies in other species, including primates.

We believe EphA2 is an attractive target for our BTCs due to the potential of Bicycles to overcome the safety

concerns observed with ADCs. In our preclinical PK and toxicokinetic studies, we observed a short half-life and volume of
distribution similar to BT1718. We observed that the accumulation of MMAE in the tumor tissue led to mitotic arrest of
tumor cells and tumor regression was evident within days of administration. Due to the shorter half-life, improved
penetration into solid tumors and kidney elimination, we believe that BT5528 could address the challenges of ADCs.
Similar to the strategy for selecting indications for BT1718, we are screening tumor TMAs using a clinically validated
EphA2 IHC, in a CAP accredited and CLIA certified laboratory, to prioritize those indications with high EphA2 protein
expression for clinical investigation.

BT5528 was evaluated in preclinical studies in multiple species, including rodents and non-human primates. In
our preclinical studies, BT5528 was not observed to have a significant effect on clotting parameters and did not exhibit
abnormal liver function at tolerated doses. We also observed no bleeding events in primates at toxin equivalent doses over
150-fold higher than the clinical dose of an ADC with the same amino acid sequence and with the same linker-toxin
combination and average drug/antibody ratio as MEDI-547 used in patients.

14

Table of Contents

Clinical Development

BT5528 is currently being evaluated in the dose escalation, Phase I portion of a company-sponsored Phase I/II 

clinical trial of patients with advanced solid tumors associated with EphA2 expression.  BT5528 has been dosed up to 8.5 
mg/m2 weekly, which we believe, based on pre-clinical studies, is toward the top of the therapeutic range, with transient
neutropenia observed at that dose. Dose finding for the Phase II portion of the trial remains ongoing, and additional weekly
and every other week doses are currently being explored. Currently administered doses are in the predicted therapeutic
range, delivering over 15 times more toxin than MedImmune’s EphA2 ADC MEDI-547. In addition, and in contrast to the
adverse events observed with MEDI-547, we have observed no signs of coagulopathy to date.

The clinical pharma profile of BT5528 is consistent with preclinical predictions. Early data received from tumor

biopsies reveal that 24 hours after infusion of BT5528, tumor levels of the MMAE cytotoxin payload are approximately ten
times higher than the corresponding plasma levels. Emerging, qualitative metabolite identification data from the clinical
trial supports the hypothesis that BTCs undergo reduced hepatic metabolism and are eliminated renally.

Although dosing continues to be refined, we have observed preliminary findings consistent with anti-tumor

activity. An EphA2 IHC assay was deployed during 2020, enabling pre-selection of patients in the Phase I portion of the
trial. Since implementation of the IHC assay, patients are prospectively screened and are eligible for enrollment based on a
prespecified H-score.

As of January 14, 2021, two EphA2-selected patients have enrolled in the trial, one of whom was response
evaluable. In the response evaluable, prospectively screened, EphA2-positive patient, a urothelial patient currently
receiving 6.5 mg/m2 of BT5528 every other week, whose prior lines of therapies included both a PD-1 inhibitor and
enfortumab vedotin, we observed a 43% reduction in target lesions at the first radiologic response assessment, constituting
a partial response under RECIST version 1.1 criteria. We also observed reductions in non-target lesions, and the patient
remains enrolled in the trial.

In addition, an ovarian cancer patient, enrolled prior to implementation of the EphA2 assay, currently receiving

4.4mg/m2 of BT5528 every week, who had been previously treated with chemotherapy, a vascular endothelial growth
factor, or VEGF inhibitor, and a poly (ADP ribose) polymerase, or PARP, inhibitor, has achieved an ongoing 25%
reduction in target lesions, which constitute stable disease. The patient, first dosed in May 2020, has completed eight cycles
of BT5528 and remains enrolled in the trial. We retrospectively analyzed the patient for EphA2 status and determined the
patient to be positive but below the current enrollment H-score cutoff.

We are currently enrolling patients in this trial at five active clinical sites, including four in the United States and

one in the United Kingdom. We expect that up to five additional sites will open in the first half of this year, primarily in the
United Kingdom and Europe. We expect a planned total of up to 17 worldwide sites to be active in 2021, with sites
prioritizing the enrollment of eligible EphA2-positive patients in the monotherapy cohorts.

BT8009

BT8009 is a BTC designed to target Nectin-4, a well-validated tumor antigen. The molecule is comprised of our

Nectin-4 targeting Bicycle, a val-cit cleavable linker, and a cytotoxin MMAE payload.

Schematic of BT8009

Nectin-4 (also known as PVRL4) is a cell adhesion molecule from the Nectin and Nectin-like family, members of

which are integral to the formation of the homotypic and heterotypic cell junctions. Nectin-4 has been shown to be
overexpressed in tumor cells and is believed to play a role in tumor cell growth and proliferation. High in normal
embryonic and fetal tissue, Nectin-4 declines in adulthood, showing a limited distribution in healthy tissues. However,
Nectin-4 is expressed on tumor cells in numerous cancer types including bladder, breast, gastric, lung and ovarian. In
addition, we believe the favorable characteristics of BTC-targeted therapies may address some of the challenges in treating
pancreatic cancer.

We are aware of one Nectin-4 ADC program in development, enfortumab vedotin, which is being jointly

conducted by Seattle Genetics and Astellas and, in December 2019, received approval from the U.S. Food and Drug
Administration, or FDA, as a treatment for patients with locally advanced or metastatic urothelial cancer following
treatment with platinum-based chemotherapy and a PD-1 or PD-L1 inhibitor. Similar to our strategy for selecting
indications for BT1718 and BT5528, we will screen tumor TMAs using a clinically validated Nectin-4 IHC to prioritize
indications with high Nectin-4 protein expression for clinical investigation.

Clinical Experience

BT8009 is advancing in the Phase I portion of the company-sponsored Phase I/II clinical trial. Early clinical data
supports a PK profile that is consistent with both preclinical predictions and data to date from our ongoing Phase I trial of
BT5528, which utilizes the same linker and toxin payload.

Enrollment in the Phase I/II trial of BT8009 is ongoing at 2 sites in the United States and our first clinical site

outside of the United States opened in the first quarter of 2021. We expect up to nine additional sites to open, primarily in
Europe and the United Kingdom in the first half of 2021, with further geographic expansion later in 2021. In total, we
expect up to 21 clinical sites to be open, with prioritization given to enrolling appropriate Nectin-4-positive patients in the
monotherapy cohorts.

Bicycle Immune Cell Agonist

Approaches that activate cytotoxic T-cells and other types of cells used in a body’s immune response have been

observed to improve outcomes in cancer. However, prolonged immune activation can be toxic and lead to T-cell
exhaustion, which is a challenge amplified by the long half-life of antibodies and biologics that are often used in these
treatment approaches. We believe the differentiated properties of Bicycles may allow us to develop molecules with a
pharmacodynamically distinct and improved profile over existing therapies.

16

Table of Contents

We are aware of anti-CD137 antibodies undergoing clinical testing, including urelumab being developed by

Bristol-Myers Squibb, which produced single agent responses but also severe liver toxicity, and utomilumab being
developed by Pfizer, which exhibited minimal clinical activity with less toxicity. We are developing immune cell agonists,
designed to trigger an immune response to tumors. We have identified potent Bicycle agonists of CD137, a tumor necrosis
factor receptor, or TNFR, family member. We believe that Bicycles represent a differentiated approach to target CD137 that
may confer several advantages over existing modalities due to the small size and PK characteristics of Bicycles. Our
Bicycle immune cell agonists are designed to circumvent the limitations of antibody and biologic therapies, such as liver
toxicity and limited efficacy, and to better enable combination therapy. Bicycle immune cell agonists can be formed by
conjugating multiple copies of a CD137 Bicycle to form multimers or by utilizing a bi-specific format in which CD137
Bicycles are linked to Bicycles that bind to tumor antigens, inhibit checkpoint proteins or otherwise activate the immune
system. We believe we are currently the only company that has fully chemically synthetic multivalent or tumor-targeted
CD137 agonists.

Properties of Bicycle Immune Cell Agonists

In order to agonize the CD137 receptor, cross-linking of a trimeric receptor is required. As a result, we are

developing multivalent systemic and tumor-targeted molecules that cross-link the receptor into an active form in a tumor
cell independent or dependent manner as shown in the image below.

Schematic of Proposed CD137 Bicycle Agonists

These Bicycle CD137 agonists feature the following favorable pharmacological characteristics for immuno-

oncology therapeutics. We believe these characteristics have the potential to overcome the limitations of antibodies and
fusion proteins.

● Simplicity and small size.  Our systemic and tumor-targeted immune cell agonizing Bicycles are chemically
synthesized and are very small in comparison to other molecules targeting the CD137 receptor. For example,
the approximate molecular weight of urelumab is 146 kDa. In contrast, the molecular weight of our
multivalent and tumor-targeted Bicycles are in the range of approximately 4 kDa to 15 kDa, which is
designed to facilitate the rapid penetration of the therapeutic into tumor tissue.

● Tunable PK.  Bicycles are amenable to chemical modifications that allow the PK to be fine-tuned. We believe
this enables the development of molecules with the optimal balance of prolonged CD137 agonism, but with
rapid enough elimination from systemic circulation to avoid the undesired toxicities of CD137, as has been
observed with urelumab. In addition, this tunable half-life is expected to enable different

17

Table of Contents

sequences of therapeutics to be evaluated in the clinic potentially reducing the risk of overlapping toxicities.

● Renal elimination.  Rapid renal elimination may avoid liver toxicity observed with other CD137 agonists in

development.

● Modular.  The modular nature of Bicycles permits the presentation of CD137 binders in various orientations
and in combination with other Bicycles allowing us to design molecules with a range of activities. We believe
that we can select the optimal activity profile to avoid the weak efficacy seen with the utomilumab molecule
or the overstimulation of CD137 by urelumab that resulted in systemic toxicity.

● Tumor targeting. Combining CD137-binding Bicycles with Bicycles that bind to tumor targets potentially
affords an additional level of safety as compared to systemically active agonists such as urelumab. The
clustering and activation of CD137 occurs only when the tumor-targeting Bicycle binds to both the tumor
antigen target and CD137. Therefore, we expect the tumor targeted agonists will achieve a higher degree of
activation locally in the tumor but will have significantly reduced or no activity in healthy tissues that do not
express the tumor antigen.

Comparison of the Features of our Bicycle Immune Cell Agonists to Biological Immune Cell Modulators

Preclinical Experience

Multivalent CD137 Immune Cell Agonists

We observed that simple multivalent Bicycle CD137 agonists displayed potent activity in preclinical cell-based

assays. Several Bicycle CD137 agonists displayed comparable or higher fold induction compared to the natural ligand
(CD137L) in an engineered reporter cell assay whereby CD137 activation leads to production of a luminescence signal. We
also observed Bicycles stimulated the release of the cytokine IL-2, a marker of immune response, from primary human T-
cells. In additional in vivo studies, we observed that CD137-binding Bicycles increased the cytotoxic T-cell infiltration in
tumor tissue. The Bicycles did not significantly change the expression of CD137 on tumoral T-cells while urelumab led to a
decrease in the target cell population. We believe this increased cytotoxic T-cell infiltration correlates with the anti-tumor
activity of the Bicycle CD137 agonists.

Bicycle Tumor-Targeted Immune Cell Agonists (TICAs)

We have linked immune cell receptor binding Bicycles to tumor antigen binding Bicycles to form TICAs. We have

found this approach to be generalizable across tumor antigen and immune cell receptors. We constructed CD137-

18

Table of Contents

targeting TICA molecules and observed that these bi-specific Bicycles agonize the CD137 receptor only in the presence of
cells that express the appropriate tumor antigen. Additionally, we have constructed TICA molecules with Bicycles that bind
to another member of the TNF family of T-cell costimulatory receptors TNFRSF4, also known as OX40.  As shown in the 
figure below, TICA molecules combining our Nectin-4 or EphA2 tumor antigen binding Bicycles and CD137 or OX40
binding Bicycles stimulated the release of the cytokine IL-2 or IFN(cid:0) from human PBMCs when in co-culture with tumor
cells that express appropriate receptor (Nectin-4 or EphA2). In co-culture with cells lacking Nectin-4 expression, or when
non-binding Bicycles are incorporated (such as BCY12759) there was no activity observed. This is an example of how both
the immune cell binding and tumor cell binding Bicycles can be readily interchanged in the context of our synthetic TICA
molecules to generate novel and targeted immune agonists for further study.

Modularity of TICAs

In our preclinical development of TICA molecules, we have observed an ability to tune molecules based on
simple chemical changes, which we believe is an inherent advantage of our Bicycle platform-based approach to bi-specifics
compared to other modalities. As an example of this, activity of two different Nectin-4/CD137 TICA molecules is shown
below. BCY10000 was observed to have a higher affinity CD137 binding Bicycle than BCY8854, yielding increased
activity and potency in a CD137 assay.

Tunable Activity of CD137 TICAs

19

Table of Contents

We also observed that the pharmacokinetic properties of TICA molecules can be tuned through chemical changes.

The figure below shows the plasma concentrations over time of three Nectin-4/CD137 TICA molecules after intravenous
infusion into rats at a dose of 3 mg/kg. BCY11863 demonstrates a longer circulation time than BCY10000 and BCY10572.
This data shows that the properties of the TICAs can be modulated to extend the duration of exposure in vivo.

Tunable Pharmacokinetics of CD137 TICAs

In further studies, we have observed that intermittent dosing of BCY12491, an EphA2/CD137 TICA, leads to a

robust anti-tumor activity in syngeneic MC38 mouse model using humanized CD137 (huCD137) C57BL/6 mice.
Administration of BCY12491 in six intravenous biweekly doses over a period of 17 days at 5 mg/kg led to substantial
tumor regressions, including two out of six CRs. In addition, administration of BCY13626, a non-binding analog of
BCY12491 had no impact on tumor growth rates.

Activity of EphA2 TICA in vivo

We have also observed that intermittent dosing of TICA BCY12491 leads to an increase in immune cell
infiltration and an increase in the expression of checkpoint inhibitor genes in tumors of a syngeneic MC38 mouse model
using humanized CD137, or huCD137, C57BL/6 mice. In other studies, we have observed that when BCY12491 is dosed
in combination with pembrolizumab, a PD1 checkpoint inhibitor, there is an increased antitumor effect as shown in the
figure below. Administration of BCY12491 in eight intravenous doses at 5 mg/kg (dosed on days 0, 1, 7, 8, 14, 15, 21 and
22) in combination with 4 intraperitoneal doses of pembrolizumab at 3 mg/kg (dosed on days 0, 7, 14 and 21) lead to
substantial tumor regressions, including ten out of ten CRs. We observed that dosing BCY12491 or pembrolizumab alone
using the same dose and schedule led to only two and three out of ten complete regressions respectively.

20

Activity of NK TICAs and PD1 Inhibitor  in vivo

We believe that our ability to rapidly generate and test TICA molecules and their simple molecular format may
form the basis of additional programs in the future. In addition to the immune cell and tumor targets that we have already
investigated, we are screening for Bicycles that target NK cell receptors as well as additional immune cell and tumor
specific antigens. We have identified TICA candidates that target and activate NK cells as shown in the figure below. We
have observed that treatment of primary human NK cells in co-culture with target-positive tumor cells with NK TICA1 or
NK TICA2 results in increased surface levels of CD107a, a marker of NK cell functional activity.

BT7480

BT7480 is a TICA that targets CD137 and Nectin-4. BT7480 exhibits potent CD137 agonism in an engineered

CD137 reporter assay system that correlates with Nectin-4 surface expression on the co-cultured tumor cells. In addition,
BT7480 induces robust production of interleukin-2, or IL-2, and interferon gamma, or IFN(cid:0), in primary PBMC/tumor cell
co-culture assays. This activity is strictly dependent on the tumor cells expressing Nectin-4 and on the ability of the TICA
to bind to both of its targets, Nectin-4 and CD137. In the figure below, BT7480 induces IL-2 and IFN(cid:0) at sub nanomolar
concentrations when incubated with human PBMCs and the Nectin-4 expressing human tumor cell line HT1376.

BT7480 produces IL-2 and IFN(cid:0) in coculture with PBMC and HT1376

Additionally, we have observed that intermittent dosing of BT7480 leads to a robust anti-tumor activity in

syngeneic MC38 mouse model, engineered to overexpress Nectin-4, using huCD137 C57BL/6 mice. Administration of
BT7480 in six intravenous biweekly doses over a period of 17 days at 1.5 or 5 mg/kg led to substantial tumor regressions,
including five out of six complete responses at 1.5 mg/kg and six out of six CRs at 5 mg/kg. In addition, animals that were
complete responders in the experiment were subsequently re-challenged with the same tumor cell implantation and no
tumor growth was observed, implying development of immunogenic memory.

Our IND-enabling activities for BT7480 are ongoing, and we expect to initiate a Phase I clinical trial in the second

half of 2021.

BT7455

BT7455 is a TICA targeting EphA2 and CD137. In preclinical studies, BT7455 was observed to potentiate

cytokine production by pre-activated PBMCs in co-culture with EphA2-expressing cancer cell lines and was associated
with tumor growth inhibition and formation of immunologic memory in mice bearing subcutaneous MC38 tumors. IND-
enabling studies for BT7455 are currently ongoing.

Genentech Collaboration

In February 2020, we entered into a strategic early discovery collaboration agreement with Genentech, Inc., a

member of the Roche Group, or Genentech, to discover, develop and commercialize novel Bicycle-based immuno-
oncology therapies. Under the collaboration, we will explore the application of our technology to a wider range of
immuno-oncology targets, combining the expertise of both companies.

Beyond Oncology

We have entered into several collaborations outside of our internal focus in oncology to leverage the broad

applicability of Bicycles. Our strategic collaborations are based on the ability of Bicycles to address a wide variety of
targets and we are working with collaborators with deep therapeutic expertise outside of oncology to enable us to more
efficiently develop novel medicines for patients.

AstraZeneca.  In November 2016, we entered into a multi-targeted research collaboration agreement with 
AstraZeneca AB, or AstraZeneca, with a focus on targets within respiratory, cardiovascular and metabolic disease.

Oxurion.  In August 2013, we entered into a research collaboration and license agreement with Oxurion NV 

(formerly ThromboGenics NV), or Oxurion, focused on ophthalmology. The lead molecule of the partnership is THR-149, 
a novel plasma kallikrein inhibitor, for the treatment of diabetic macular edema. A Phase I clinical trial of THR-149 was 
completed in July 2019. The Phase I clinical trial, conducted by Oxurion, was an open-label, multi-center, non-randomized 
study to evaluate the safety of a single intravitreal injection of THR-149 at three ascending dose levels in 12 subjects with 
visual impairment due to center-involved DME. The study also investigated changes to patients’ best corrected visual 
acuity (BCVA). A rapid onset of action was observed from Day 1, with an increasing average improvement in BCVA of up 
to 7.5 letters at Day 14. This activity was maintained with an average improvement in BCVA of 6.5 letters at Day 90 
following a single injection of THR-149. In September 2020, we announced that the first patient had been dosed in 
Oxurion’s Phase II study of THR-149. The Phase II trial is expected to include approximately 122 patients with central 
involved DME who do not respond adequately to anti-VEGF therapy.

activities operate through, or the Cancer Research UK Agreement. Pursuant to the agreement, as amended in March 2017
and June 2018, Cancer Research UK Centre for Drug Development will sponsor and fund a Phase I/IIa clinical trial of our
lead product candidate, BT1718, in patients with advanced solid tumors.

Cancer Research UK is responsible for designing, preparing, carrying out and sponsoring the clinical trial at its

cost. We are responsible for supplying agreed quantities of GMP materials for the study, the supply of which has been
completed. In the event that additional quantities are needed, we will provide Cancer Research UK with all reasonable
assistance to complete the arrangements necessary for the generation and supply of such additional GMP materials but
Cancer Research UK will be responsible for supplying and paying for such additional quantities of GMP materials.

We granted to Cancer Research UK a license to our intellectual property in order to design, prepare for, sponsor,
and carry out the clinical trial. We retain the right to continue the development of BT1718 during the clinical trial. Upon
the completion of the Phase I/IIa clinical study, we have the right to obtain a license to the results of the clinical trial upon
the payment of a milestone, in cash and ordinary shares, with a combined value in the mid-six digit dollar amount. If such
license is not acquired, or if it is acquired and the license is terminated and we decide to abandon development of all
products that deliver cytotoxic payloads to the MT1 target antigen, Cancer Research Technology Limited may elect to
receive an assignment and exclusive license to develop and commercialize the product on a revenue sharing basis (in which
case we will receive tiered royalties of 70% to 90% of the net revenue depending on the stage of development when the
license is granted) less certain costs, as defined by the agreement. The Cancer Research UK Agreement contains additional
future milestone payments upon the achievement of development, regulatory and commercial milestones, payable in cash
and shares, with an aggregate total value of $50.9 million, as well as royalty payments based on a single digit percentage
on net sales of products developed.

The Cancer Research UK Agreement can be terminated by either party upon an insolvency event, material breach
of the terms of the contract, or upon a change in control (and the new controlling entity generates its revenue from the sale
of tobacco products). Cancer Research UK may terminate the arrangement for safety reasons or if it determines that the
objectives of the clinical trial will not be met, in which case, if the study is terminated by Cancer Research UK prior to the
completion of the Phase I dose escalation part of the study for such reasons, or if Cancer Research UK refuses release of
any additional quantities of GMP materials, or if the parties cannot agree upon a plan to supply the additional quantities of
GMP materials, we will be obligated to refund 50% of the costs and expenses incurred or committed by Cancer Research
UK to perform the clinical trial. If the study is terminated by Cancer Research UK for an insolvency event, a material
breach by us, or if we are acquired by an entity that generates its revenue from the sale of tobacco products, we will
reimburse Cancer Research UK in full for all costs paid or committed in connection with the clinical trial and no further
license payments, where applicable, shall be due. In such case where we are acquired by an entity that generates its revenue
from the sale of tobacco products, Cancer Research UK will not be obliged to grant a license to us in respect of the results
of the clinical trial and we will assign or grant to Cancer Research Technology Limited an exclusive license to develop and
commercialize the product without Cancer Research Technology Limited being required to make any payment to us.

BT7401

In December 2019, we entered into a clinical trial and license agreement with Cancer Research Technology

Limited and Cancer Research UK. Pursuant to the agreement, Cancer Research UK Centre for Drug Development will
fund and sponsor development of BT7401 from current preclinical studies through the completion of a Phase IIa trial in
patients with advanced solid tumors.

23

Table of Contents

We granted to Cancer Research UK a license to our intellectual property in order for Cancer Research UK to

design, prepare for, sponsor, and carry out the clinical trial and all necessary preclinical activities to support the trial. We
retain the right to continue the development of BT7401 during the clinical trial. Upon the completion of the Phase I/IIa
clinical study, we have the right to obtain a license to the results of the clinical trial upon the payment of a milestone, in
cash and ordinary shares, with a combined value in the mid six-digit dollar amount. If such license is not acquired, or if it is
acquired and the license is terminated and we decide to abandon development of all products that contain BT7401 or all the
pharmaceutically active parts of BT7401, we will assign or grant to Cancer Research Technology Limited an exclusive
license to develop and commercialize the product on a revenue sharing basis (in which case we will receive tiered royalties
of 55% to 80% of the net revenue depending on the stage of development when the license is granted) less certain costs, as
defined in the agreement. The BT7401 Cancer Research UK agreement contains additional future milestone payments
upon the achievement of development, regulatory and commercial milestones, payable in cash, with an aggregate total
value of up to $60.3 million for each licensed product, as well as royalty payments based on a single digit percentage on
net sales of products developed, and sublicense royalties to the Cancer Research UK in the low double digit percentage of
sublicense income depending on the stage of development when the license is granted.

The BT7401Cancer Research UK agreement can be terminated by either party upon an insolvency event, material

breach of the terms of the contract, or upon a change in control (and the new controlling entity generates its revenue from
the sale of tobacco products), or upon written notice by either party prior to the last cycle of treatment has been completed
under the clinical trial. If the study is terminated by us prior to the filing of a clinical trial authorization, or by the Cancer
Research UK for an insolvency event or a material breach by us prior to the start of a clinical trial, we will reimburse
Cancer Research UK for certain costs paid or committed prior to the start of the clinical trial. In such case where we are
acquired by an entity that generates its revenue from the sale of tobacco products, Cancer Research UK will not be obliged
to grant a license to us in respect of the results of the clinical trial and we will assign or grant to Cancer Research
Technology Limited an exclusive license to develop and commercialize the product without Cancer Research Technology
Limited being required to make any payment to us.

Genentech

On February 21, 2020, we entered into a Discovery Collaboration and License Agreement with Genentech. The

collaboration is focused on the discovery and development of Bicycle peptides directed to biological targets selected by
Genentech and aimed at developing up to four potential development candidates against multiple I-O targets suitable for
Genentech to advance into further development and commercialization.

Under the terms of the Genentech Collaboration Agreement, we received a $30.0 million upfront, non-refundable

payment. The initial discovery and optimization activities will focus on utilizing our phage screening technology to
identify product candidates aimed at two I-O targets, or Genentech Collaboration Programs, which may also include
additional discovery and optimization of Bicycles as a targeting element for each Genentech Collaboration Program, or
each a Targeting Arm. Genentech has the option to nominate up to two additional I-O targets, or each an Expansion Option,
which may also include an additional Targeting Arm for each Expansion Option, as additional Genentech Collaboration
Programs during a specified period following completion of certain activities under an agreed research plan. If Genentech
exercises one or more Expansion Options, Genentech will pay us an expansion fee of $10.0 million per Expansion Option.
Genentech also has rights, under certain limited circumstances, to select an alternative target to be the subject of a
Genentech Collaboration Program, in some cases subject to payment of an additional target selection fee.

If Genentech elects for us to perform discovery and optimization services for certain Targeting Arms, we will be 

entitled to receive an additional advance payment for the additional research services.  Genentech exercised its right to 
select a Targeting Arm for one of the initial Genentech Collaboration Programs at the inception of the arrangement, which 
entitled us to an additional $1.0 million payment. If a Targeting Arm achieves specified criteria in accordance with the 
research plan, Genentech will be required to pay a further specified amount in the low single digit millions for each such 
Targeting Arm as consideration for the additional services to be provided.  

We granted to Genentech a non-exclusive research license under our intellectual property solely to enable

Genentech to perform any activities under the agreement. The activities under the Genentech Collaboration Agreement

24

Table of Contents

are governed by a joint research committee, or JRC, with representatives from each of Bicycle and Genentech. The JRC
will oversee, review and recommend direction of each Genentech Collaboration Program, achievement of development
criteria, and variations of or modifications to the research plans.

After we perform the initial discovery and optimization activities in accordance with an agreed research plan and 

achieves specified criteria, Genentech will have the option to have us perform initial pre-clinical development and 
optimization activities in exchange for an additional specified milestone payment in the mid-single digit millions for each 
Genentech Collaboration Program, or the LSR Go Option.  Upon completion of such initial pre-clinical development and 
optimization activities for each Genentech Collaboration Program, Genentech will have the option to obtain an exclusive 
license to exploit any compound developed under such Genentech Collaboration Program in exchange for an additional 
specified payment in the mid to high single digit millions for each of the initial two Genentech Collaboration Programs and 
each of the two Expansion Option Genentech Collaboration Programs, or the Dev Go Option. 

On a Genentech Collaboration Program by Genentech Collaboration Program basis, if Genentech elects to obtain

exclusive development and commercialization rights and pays the applicable LSR Go Option and Dev Go Option fees,
Genentech will be required to make milestone payments to us upon the achievement of specified development, regulatory,
and initial commercialization milestones for products arising from each collaboration program, totaling up to $200.0
million. Specifically, we are eligible for additional development milestones totaling up to $65.0 million, as well as
regulatory milestones of up to $135.0 million for each collaboration program. In addition, we are eligible to receive up to
$200.0 million in sales milestone payments on a Genentech Collaboration Program-by-Genentech Collaboration Program
basis. In addition, to the extent any of the product candidates covered by the licenses conveyed to Genentech are
commercialized, we would be entitled to receive tiered royalty payments on net sales at percentages ranging from the mid-
single to low double-digits, subject to certain standard reductions and offsets. Royalties will be payable, on a product by
product and country by country basis, until the later of the expiration of specified licensed patents covering such product in
such country, or ten years from first commercial sale of such product in such country.

Dementia Discovery Fund

In May 2019, we entered into a collaboration with the Dementia Discovery Fund, or DDF, to use Bicycle

technology for the discovery and development of novel therapeutics for dementia. DDF is a specialized venture capital
fund focused on discovering and developing novel therapies for dementia. In October 2019, the collaboration with DDF
was expanded to include Oxford University’s Oxford Drug Discovery Institute (ODDI). Under the terms of the agreement,
Bicycle and DDF will collaborate to identify Bicycles that bind to clinically validated dementia targets. ODDI will then
profile these Bicycles in a range of target-specific and disease-focused assays to assess their therapeutic potential. If
promising lead compounds are identified, DDF, ODDI and Bicycle will establish a jointly-owned new company to advance
the compounds through further development towards commercialization. The jointly-owned company will receive a royalty
and milestone-bearing assignment and license of intellectual property from Bicycle for this purpose.

AstraZeneca

In November 2016, we entered into a research collaboration agreement with AstraZeneca AB. The collaboration is

focused on the research and development of Bicycle peptides that bind to an undisclosed number of biological targets for
the treatment of respiratory, cardiovascular and metabolic diseases. After discovery and initial optimization of such Bicycle
peptides, AstraZeneca will be responsible for all research and development, including lead optimization and drug candidate
selection. AstraZeneca receives development, commercialization and manufacturing license rights with regard to any
selected drug candidate(s).

Under the AstraZeneca collaboration agreement, Bicycle is obligated to use commercially reasonable efforts to

perform research activities, under mutually agreed upon research plans. The research plans includes two discrete parts, on a
research program by research program basis: (i) the Bicycle Research Term, which is focused on the generation of Bicycle
peptide libraries using our peptide drug discovery platform, to be screened against selected biological targets, with the goal
of identifying compounds that meet agreed criteria set by the parties, and (ii) the AZ Research Term,

25

Table of Contents

during which AstraZeneca may continue research activities with the goal of identifying compounds that satisfy the relevant
pharmacological and pharmaceutical criteria for clinical testing. AstraZeneca may, at its sole discretion, approve any
compound to be progressed into drug development and, upon the selection of each drug candidate, AstraZeneca is to pay a
milestone of $8.0 million.

Each research program is to continue for an initial period of three years, referred to as the research term, including
one year for the Bicycle Research Term and two for the AZ Research Term. AstraZeneca may extend the research term for
each research program by twelve months (or fifteen months, if needed to complete certain toxicology studies). The
research term for a specific program can be shorter if it is ceased due to a screening failure, a futility determination, or
abandonment by AstraZeneca. AstraZeneca has certain substitution rights should a screening failure or futility
determination be reached. but is obligated to fund these additional efforts related to substitution.

Under the terms of the AstraZeneca collaboration agreement, we granted to AstraZeneca the right and license

(with the right to sublicense) to certain background, foreground and platform intellectual property, for the duration of the
agreement, to the extent reasonably necessary or useful for AstraZeneca to conduct the activities that are assigned to it in
the applicable research plan or that are reasonably necessary or useful or the purpose of researching, developing or
exploiting resulting compounds and products. We have agreed not to, directly or indirectly, by ourselves or in collaboration
with others, screen the Bicycle platform for compounds that bind to a target that is the subject of the AstraZeneca
collaboration or otherwise perform any work related to or disclose such a target until the earlier of the tenth anniversary of
the date on which such target was selected or the dosing of the first patient in the first Phase III clinical trial for a product
that modulates such collaboration target.

The activities under the AstraZeneca collaboration agreement are governed by a joint steering committee and joint

project team each formed by an equal number of representatives from our company and AstraZeneca. The joint steering
committee oversees and reviews each research program and the activities of the joint program team. Among other
responsibilities, the joint steering committee monitors the research progress and ensures open and frequent exchange
between the parties regarding research program activities.

AstraZeneca receives development and commercialization licenses associated with each designated drug

candidate, and owes a milestone fee of $8.0 million for the first drug candidate selected from each research program. In
addition, AstraZeneca is required to make certain other milestone payments to us upon the achievement of specified
development, regulatory and commercial milestones. For each research program, we are eligible to receive, in addition to
the milestone fee described above, up to $162.0 million in development, regulatory and commercial milestones on a
research program by research program basis, for a total of up to $170.0 million in milestone payments per research
program. We are eligible to receive these milestone payments for up to six research programs under the arrangement. In
addition, to the extent any of the drug candidates covered by the licenses conveyed to AstraZeneca are commercialized, we
would be entitled to receive tiered royalty payments of mid-single digits based on a percentage of net sales. Royalty
payments are subject to certain reductions, including in certain countries where AstraZeneca faces generic competition.

Either party may terminate the AstraZeneca collaboration agreement if the other party has materially breached or
defaulted in the performance of any of its material obligations and such breach or default continues after the specified cure
period. In the event of a breach, the collaboration agreement may be terminated in its entirety, or, if the breach is limited to
a country or countries, with respect to the country or countries to which the breach applies. Either party may terminate the
AstraZeneca collaboration agreement in the event of the commencement of any proceeding in or for bankruptcy,
insolvency, dissolution or winding up by or against the other party that is not dismissed or otherwise disposed of within a
specified time period. AstraZeneca may terminate the AstraZeneca collaboration agreement, entirely or on a licensed
product by licensed product or country by country basis, for convenience.

Under the AstraZeneca collaboration agreement, AstraZeneca was granted an option to nominate additional
targets on the same contractual terms as the initial targets. In May 2018, AstraZeneca made an irrevocable election to
exercise the additional target option, giving AstraZeneca the option to designate additional targets, for $5.0 million that 
was paid by AstraZeneca to us in January 2019. In October 2020, AstraZeneca terminated two research programs. As of 
December 31, 2020, three research programs were in the AZ Research Term, and one program was in the Bicycle Research 
Term.  A third program was terminated in March 2021.

Oxurion (formerly ThromboGenics)

In August 2013, we entered into a research collaboration and license agreement with Oxurion NV (formerly

ThromboGenics NV), or Oxurion. Under the Oxurion collaboration agreement, we are responsible for identifying Bicycle
peptides related to the collaboration target, human plasma kallikrein, for use in various ophthalmic indications. Oxurion is
responsible for further development and product commercialization after the defined research screening is performed by us.

The collaboration includes two stages. During Stage I, which has been completed, we were obligated to perform
specific research activities in accordance with the research plan focused on screening the target using our Bicycle platform
to identify compounds that meet the criteria set by the parties. During Stage II, which is ongoing, Oxurion has continued
research activities on selected Bicycle peptides with the goal of identifying compounds for further development and
commercialization. We are not obligated or expected to perform any research services during Stage II of the research plan.
THR-149 has been selected as a development compound under the Oxurion collaboration agreement.

We granted certain worldwide intellectual property rights to Oxurion for the development, manufacture and

commercialization of licensed compounds associated with plasma kallikrein.

The Oxurion collaboration agreement provides for certain milestone payments to us upon the achievement of

specified research, development, regulatory and commercial milestones. More specifically, for each collaboration
compound, we are eligible to receive up to €8.3 million in research and development milestone payments, from which we
have received €1.8 million as of December 31, 2020, in connection with the development of THR-149, and up to
€16.5 million in regulatory milestone payments (e.g., €5 million for granting of first regulatory approval in either the
United States or the European Union for the first indication). In addition, to the extent any of the collaboration products
covered by the licenses granted to Oxurion are commercialized, we would be entitled to receive tiered royalty payments of
mid-single digits based on a percentage of net sales. Royalty payments are subject to certain reductions. Also, if Oxurion
grants a sublicense to a third party for rights to the program for non-ophthalmic use prior to the filing of an IND, we would
be entitled to receive payments in the double digits (no higher than first quartile) based on a percentage of non-royalty
sublicensing income. If Oxurion grants a sublicense to a third party for rights to the program for non-opthalmic use after
the filing of an IND, we would be entitled to receive payments of mid-single digits to low teen-digits.

Either party may terminate the Oxurion collaboration agreement if the other party has breached any of its material
obligations and such breach continues after the specified cure period. Either party may terminate the Oxurion collaboration
agreement in the event of the commencement of any proceeding in or for bankruptcy, insolvency, dissolution or winding up
by or against the other party. Oxurion may terminate the Oxurion collaboration agreement for convenience. We may
terminate the Oxurion collaboration agreement if Oxurion challenges the validity of any licensed patents or opposes the
grant of a licensed patent.

Founder Royalty Arrangements

We have entered into two royalty agreements with our founders, Christian Heinis, John Tite, and Sir Greg Winter,

and our initial investors, Atlas Venture Fund VIII LP, Novartis Bioventures LTD. Pursuant to the first royalty agreement,
we are obligated to pay an aggregate royalty percentage in the low single digits on net sales arising from products licensed
under the Oxurion collaboration agreement. Pursuant to the second royalty agreement, we are obligated to pay an aggregate
royalty percentage in the low single digits on net sales arising from products licensed under the AstraZeneca collaboration
agreement.

Intellectual Property

Overview

We strive to protect and enhance the proprietary technology, inventions, and improvements that are commercially

important to the development of our business, including our Bicycle platform. This includes seeking, maintaining, and
defending patent rights, whether developed internally or licensed from third parties, which are directed to the use of our
Bicycle platform and composition of matter involved in the platform, composition of matter and use of product candidates,
and other inventions that are important to our business. As of December 31, 2020, we had four patent families directed to
novel scaffolds, and 15 patent families directed to our platform technology, including the composition of matter of Bicycle 
binders and method of treatment of related indications, including cancer. For example, a patent family directed to the 
composition of matter of Bicycle binders and method of treatment of related indications, including cancer, was issued in 
the United States and Europe, and is pending in several other jurisdictions.  The issued patents from this family, and the 
pending patent applications if issued, are expected to expire in 2034, before patent term extensions, if any. As of December 
31, 2020, we had 74 patent families directed to bicyclic peptides and related conjugates, and ten patent families directed to 
methods of using certain bicyclic peptide conjugates for treating various indications. For example, we have (i) at least two 
patent families directed to the composition of matter of one of our product candidates, BT1718, and methods of use for 
treating cancer, which are pending in certain jurisdictions, and if issued, would expire in 2035 and 2037, respectively; (ii) 
at least two patent families directed to the composition of matter our product candidate, BT5528, and methods of use for 
treating cancer, which are pending in certain jurisdictions, and if issued, would expire in 2038 and 2040, respectively; and 
(iii) at least two patent families directed to the composition of matter our product candidate, BT8009, and methods of use 
for treating cancer, which are pending in certain jurisdictions, and if issued, would expire in 2039 and 2041, respectively. 
We also rely on trade secrets and know-how that may be important for the development of our business. This includes 
aspects of our proprietary technology platform and our continuing technological innovation to develop, maintain, and 
strengthen our position in the field of peptide, peptidomimetic, and small molecule-based therapeutics. We additionally 
may rely on regulatory protection afforded through data exclusivity, market exclusivity and patent term extensions where 
available.

Our commercial success may depend in part on our ability to obtain and maintain patent and other proprietary
protection for our product candidates, technology and know-how, defend and enforce our patents; prevent others from
infringing our proprietary rights, preserve the confidentiality of our trade secrets, and to operate without infringing the
proprietary rights of others.

Our ability to stop third parties from making, having made, using, selling, offering to sell or importing our

products may depend on the extent to which we have rights under valid and enforceable licenses, patents or trade secrets
that cover these activities. In some cases, these rights may need to be enforced by third party licensors. With respect to both
licensed and company-owned intellectual property, we cannot be sure that patents will be granted with respect to any of our
pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any
of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our
commercial products and methods of manufacturing the same. For more information, please see “Risk Factors — Risks
Related to Our Intellectual Property.”

We seek to protect our proprietary position in a variety of ways, including by pursuing patent protection in certain

jurisdictions where it is available. For example, we file U.S. and certain foreign patent applications related to our
proprietary technology, inventions and improvements that are important to the development of our business. We also intend
to seek patent protection or rely upon trade secret rights to protect other technologies that may be used to discover and
validate targets and that may be used to identify and develop novel products. We seek protection, in part, through
confidentiality and proprietary information agreements. We are a party to various other license agreements that give us
rights to use specific technologies in our research and development.

The term of individual patents depends upon the legal term of the patents in the countries in which they are

obtained. In most countries in which we file, the patent term is 20 years from the earliest date of filing a non-provisional
patent application related to the patent. A U.S. patent also may be accorded a patent term adjustment, or PTA, under certain
circumstances to compensate for delays in obtaining the patent caused by the United States Patent and Trademark

28

Table of Contents

Office, or USPTO. In some instances, such a PTA may result in a U.S. patent term extending beyond 20 years from the
earliest date of filing a non-provisional patent application related to the U.S. patent. In addition, in the United States, the
term of a U.S. patent that covers an FDA-approved drug may also be eligible for patent term extension, which permits
patent term restoration as compensation for the patent term lost during the FDA regulatory review process. The Hatch-
Waxman Act permits a patent term extension of up to five years beyond the expiration of the patent. The length of the
patent term extension is related to the length of time the drug is under regulatory review. Patent term extension cannot
extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only one patent
applicable to an approved drug may be extended. Similar provisions are available in Europe and other foreign jurisdictions
to extend the term of a patent that covers an approved drug. In the future, if and when our products receive FDA approval,
we expect to apply for patent term extensions on patents covering those products. We plan to seek patent term extensions to
any of our issued patents in any jurisdiction where these are available, however there is no guarantee that the applicable
authorities, including the FDA in the United States, will agree with our assessment of whether such extensions should be
granted, and if granted, the length of such extensions.

We own various trademark registrations and applications, and unregistered trademarks, including our name and

our corporate logo. All other trade names, trademarks and service marks of other companies appearing in this report are the
property of their respective holders. Solely for convenience, the trademarks and trade names in this report may be referred
to without the ®,™ or © symbols, but such references should not be construed as any indicator that their respective owners
will not assert, to the fullest extent under applicable law, their rights thereto. We do not intend to use or display other
companies' trademarks and trade names to imply a relationship with, or endorsement or sponsorship of us by, any other
companies.

Company-Owned Intellectual Property

As of December 31, 2020, our patent portfolio included four patent families directed to novel scaffolds, 15 patent
families directed to our platform technology, 74 patent families directed to bicyclic peptides and related conjugates, and ten
patent families directed to methods of using certain bicyclic peptide conjugates for treating various indications. In total, as
of December 31, 2020, we owned about 75 patents in the United States and in foreign jurisdictions, such as Australia,
Canada, China, Europe, Hong Kong, Japan, New Zealand, Russia and Singapore, with terms expiring at various dates in
February 2029 to February 2039 exclusive of potential patent term adjustment and/or patent term extension.

In addition, as of December 31, 2020, we had about 280 patent applications pending in the United States and in
foreign jurisdictions, such as Argentina, Australia, Brazil, Canada, China, Europe, Hong Kong, India, Japan, Korea, New
Zealand, Russia, Singapore, Taiwan, and Venezuela, as well as pending international applications under the Patent
Cooperation Treaty, or PCT, and any patents that may be issued from these patent applications are generally expected to
have terms that will expire at various dates in February 2029 to December 2041, subject to possible patent term extensions
and/or patent term adjustments.

Trade Secret Protection

Finally, we may rely, in some circumstances, on trade secrets to protect our technology. We anticipate relying on
trade secrets to protect the know-how behind our Bicycle platform. However, trade secrets can be difficult to protect. We
seek to protect our technology and processes, in part, by entering into confidentiality agreements with our employees,
consultants, scientific advisors and contractors. We also seek to preserve the integrity and confidentiality of our data and
trade secrets by maintaining physical security of our premises and physical and electronic security of our information
technology systems. While we have confidence in these individuals, organizations and systems, agreements or security
measures may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets may
otherwise become known or be independently discovered by competitors. To the extent that our consultants, contractors or
collaborators use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or
resulting know-how and inventions. For further information, please see “Risk Factors — Risks Related to Our Intellectual
Property.”

Table of Contents

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense

competition and a strong emphasis on proprietary products. While we believe that our technologies, knowledge, experience
and scientific resources provide us with competitive advantages, we face potential competition from many different
sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions and
governmental agencies and public and private research institutions. Any product candidates that we successfully develop
and commercialize will compete with existing therapies and new therapies that may become available in the future.

There are a number of currently marketed products and product candidates in preclinical research and clinical

development by third parties for the various oncology applications that we are targeting. For example, a number of
multinational companies as well as large biotechnology companies, including Astellas Pharma, Inc., Seattle Genetics, Inc.,
AstraZeneca, GlaxoSmithKline plc, and Stemline Therapeutics Inc. are developing programs for the targets that we are
exploring for our BTC programs. Furthermore, Agenus Inc., Bristol-Myers Squibb Company, Pfizer Inc., and Roche 
Holding AG, or Roche, have or are developing programs for CD137, and Amgen Inc., Pieris Pharmaceuticals, Inc.  and 
Roche are developing bi-specific antibodies. In addition, we are aware that technologies for drug discovery, including 
peptide-based medicines, continue to advance rapidly, which may compete with our own screening technology or render it 
obsolete.

Many of our competitors, either alone or with their strategic partners, have substantially greater financial,

technical and human resources than we do and significantly greater experience in the discovery and development of
product candidates, obtaining FDA and other regulatory approvals of products and the commercialization of those
products. Accordingly, our competitors may be more successful than we may be in discovering product candidates,
obtaining approval for drugs and achieving widespread market acceptance. Our competitors’ drugs may be more effective,
or more effectively marketed and sold, than any drug we may commercialize and may render our product candidates
obsolete or non-competitive before we can recover the expenses of developing and commercializing any of our product
candidates. We anticipate that we will face intense and increasing competition as new drugs enter the market and advanced
technologies become available.

Sales and Marketing

Subject to receiving marketing approval, we intend to pursue the commercialization of our product candidates

either by building internal sales and marketing capabilities or through opportunistic collaborations with others.

We plan to build a marketing and sales management organization to create and implement marketing strategies for

any products that we market through our own sales organization and to oversee and support our sales force. The
responsibilities of the marketing organization would include developing educational initiatives with respect to approved
products and establishing relationships with researchers and practitioners in relevant fields of medicine.

Manufacturing

Each of our Bicycles is entirely synthetic. We believe the synthetic nature of our product candidates allow for a

more cost effective and scalable manufacturing process compared to biologics. In addition, this property of Bicycles allows
for the manufacturing of product candidates of consistent pharmaceutical quality with favorable stability characteristics.
Based on our experience, we believe that the manufacturing of Bicycles can be made to be well controlled, reproducible
and scalable.

We operate an outsourced model for the manufacture of our product candidates, and contract with good
manufacturing practice, or GMP, licensed pharmaceutical contract development and manufacturing organizations, both for
the synthesis of each drug substance component, and the formulation and packaging of the finished drug product. We
selected these organizations based on their experience, capability, capacity and regulatory status. We do not own or operate
GMP manufacturing facilities, nor do we currently plan to build our own GMP manufacturing capabilities for the
production of candidates for clinical or commercial use.

30

Table of Contents

We currently engage five third-party manufacturers to provide clinical supplies of our product candidates, three

third-party manufacturers to provide non-clinical supplies of our product candidates and three third-party manufacturers to
provide fill-finish services. Projects are managed by a specialist team of our internal staff, which is designed to promote
compliance with the technical aspects and regulatory requirements of the manufacturing process.

Government Regulation

Government authorities in the United States, at the federal, state and local level, and in other countries and

jurisdictions, including the European Union, extensively regulate, among other things, the research, development, testing,
manufacture, quality control, approval, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution,
marketing, post-approval monitoring and reporting, and import and export of pharmaceutical products. The processes for
obtaining regulatory approvals in the United States and in foreign countries and jurisdictions, along with subsequent
compliance with applicable statutes and regulations and other regulatory authorities, require the expenditure of substantial
time and financial resources.

Review and Approval of Drugs in the United States

In the United States, the FDA regulates drugs and devices under the Federal Food, Drug, and Cosmetic Act, or

FDCA, and implementing regulations. The failure to comply with applicable U.S. requirements at any time during the
product development process, approval process or after approval may subject an applicant and/or sponsor to a variety of
administrative or judicial sanctions, including refusal by the FDA to approve pending applications, withdrawal of an
approval, imposition of a clinical hold, issuance of warning letters and other types of letters, product seizures, total or
partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution,
disgorgement of profits, or civil or criminal investigations and penalties brought by the FDA and the Department of Justice
or other governmental entities. In addition, an applicant may need to recall a product.

An applicant seeking approval to market and distribute a new drug product in the United States must typically

undertake the following:

● completion of nonclinical, or preclinical, laboratory tests, animal studies and formulation studies in

compliance with the FDA’s good laboratory practice, or GLP, regulations;

● submission to the FDA of an IND, which must take effect before human clinical trials may begin;

● approval by an independent IRB representing each clinical site before each clinical trial may be initiated;

● performance of adequate and well-controlled human clinical trials in accordance with good clinical practices,

or GCP, to establish the safety and efficacy of the proposed drug product for each indication;

● preparation and submission to the FDA of a new drug application, or NDA;

● review of the product by an FDA advisory committee, where appropriate or if applicable;

● satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which

the product, or components thereof, are produced to assess compliance with current Good Manufacturing
Practices, or cGMP, requirements and to assure that the facilities, methods and controls are adequate to
preserve the product’s identity, strength, quality and purity;

● satisfactory completion of FDA audits of clinical trial sites to assure compliance with GCPs and the integrity

of the clinical data;

● payment of user fees and securing FDA approval of the NDA; and

31

● compliance with any post-approval requirements, including Risk Evaluation and Mitigation Strategies, or

REMS, and post-approval studies required by the FDA.

Preclinical Studies

Preclinical studies include laboratory evaluation of the purity and stability of the manufactured drug substance or
active pharmaceutical ingredient and the formulated drug or drug product, as well as in vitro and animal studies to assess
the safety and activity of the drug for initial testing in humans and to establish a rationale for therapeutic use. The conduct
of preclinical studies is subject to federal regulations and requirements, including GLP regulations. The results of the
preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and plans
for clinical trials, among other things, are submitted to the FDA as part of an IND. Some long-term preclinical testing, such
as animal tests of reproductive adverse events and carcinogenicity, may continue after the IND is submitted.

Human Clinical Trials in Support of an NDA

Clinical trials involve the administration of the investigational product to human subjects under the supervision of

qualified investigators in accordance with GCP requirements, which include, among other things, the requirement that all
research subjects provide their informed consent in writing before their participation in any clinical trial. Clinical trials are
conducted under written study protocols detailing, among other things, the inclusion and exclusion criteria, the objectives
of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A protocol for
each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. An IND
automatically becomes effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or
questions related to a proposed clinical trial and places the trial on clinical hold. In such a case, the IND sponsor and the
FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA can place an IND on full or partial
clinical hold at any point in development, and depending upon the scope of the hold, clinical trial(s) may not restart until
resolution of the outstanding concerns to the FDA’s satisfaction.

In addition, an IRB representing each institution participating in the clinical trial must review and approve the

plan for any clinical trial before it commences at that institution, and the IRB must conduct a continuing review and
reapprove the study at least annually. The IRB must review and approve, among other things, the study protocol and
informed consent information to be provided to study subjects. An IRB must operate in compliance with FDA regulations.
Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health
for public dissemination on their ClinicalTrials.gov website.

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

● Phase I.  The drug is initially introduced into healthy human subjects or, in certain indications such as cancer,
patients with the target disease or condition and tested for safety, dosage tolerance, absorption, metabolism,
distribution, excretion and, if possible, to gain an early indication of its effectiveness and to determine
optimal dosage.

● Phase II.  The drug 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 diseases and to
determine dosage tolerance and optimal dosage.

● Phase III.  The drug is administered to an expanded patient population, generally at geographically dispersed
clinical trial sites, in well-controlled clinical trials to generate enough data to evaluate the efficacy and safety
of the product for approval, to establish the overall risk-benefit profile of the product and to provide adequate
information for the labeling of the product.

● Phase IV.  Post-approval studies may be conducted after initial marketing approval. These studies are used to

gain additional experience from the treatment of patients in the intended therapeutic indication.

32

Table of Contents

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more

frequently if serious adverse events occur. In addition, IND safety reports must be submitted to the FDA for any of the
following: serious and unexpected suspected adverse reactions; findings from other studies or animal or in vitro testing that
suggest a significant risk in humans exposed to the drug; and any clinically important increase in the case of a serious
suspected adverse reaction over that listed in the protocol or investigator brochure. Phase I, Phase II and Phase III clinical
trials may not be completed successfully within any specified period, or at all. Furthermore, the FDA or the sponsor may
suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being
exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its
institution, or an institution it represents, 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. The FDA will typically inspect
one or more clinical sites to assure compliance with GCP and the integrity of the clinical data submitted.

Concurrent with clinical trials, companies often complete additional animal studies and must also develop
additional information about the chemistry and physical characteristics of the drug as well as finalize a process for
manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process
must be capable of consistently producing quality batches of the drug candidate and, among other things, the applicant
must develop methods for testing the identity, strength, quality, purity, and potency of the final drug. Additionally,
appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug
candidate does not undergo unacceptable deterioration over its shelf life.

Review of an NDA by the FDA

Assuming successful completion of required clinical testing and other requirements, the results of the preclinical
studies and clinical trials, together with detailed information relating to the product’s chemistry, manufacture, controls and
proposed labeling, among other things, are submitted to the FDA as part of an NDA requesting approval to market the drug
product for one or more indications. Under federal law, the submission of most NDAs is additionally subject to substantial
user fees, and the sponsor of an approved NDA is also subject to annual program user fees. These fees are typically
increased annually.

The FDA conducts a preliminary review of an NDA within 60 days of its receipt and informs the sponsor whether

the application is sufficiently complete to permit substantive review. The FDA may request additional information rather
than accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The
resubmitted application is also subject to review before the FDA accepts it for filing. Once the submission is accepted for
filing, the FDA begins an in-depth substantive review. 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 of filing, and most
applications for “priority review” products are meant to be reviewed within six months of filing. The review process may
be extended by the FDA for three additional months to consider new information or clarification provided by the applicant
to address an outstanding deficiency identified by the FDA following the original submission.

Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is or will be
manufactured. These pre-approval inspections may cover all facilities associated with an NDA submission, including drug
component manufacturing (such as active pharmaceutical ingredients), finished drug product manufacturing, and control
testing laboratories. The FDA will not approve an application unless it determines that the manufacturing processes and
facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within
required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical sites to
assure compliance with GCP.

In addition, as a condition of approval, the FDA may require an applicant to develop a REMS. REMS use risk

minimization strategies beyond the professional labeling to ensure that the benefits of the product outweigh the potential
risks. To determine whether a REMS is needed, the FDA will consider the size of the population likely to use the product,
seriousness of the disease, expected benefit of the product, expected duration of treatment, seriousness of known or
potential adverse events, and whether the product is a new molecular entity. REMS can include medication

33

Table of Contents

guides, physician communication plans for healthcare professionals, and elements to assure safe use, or ETASU. ETASU
may include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under
certain circumstances, special monitoring, and the use of patient registries. The FDA may require a REMS before approval
or post-approval if it becomes aware of a serious risk associated with use of the product. The requirement for a REMS can
materially affect the potential market and profitability of a product.

The FDA is required to refer an application for a novel drug to an advisory committee or explain why such

referral was not made. 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 recommendations of an advisory committee, but it considers such
recommendations carefully when making decisions.

Fast Track, Breakthrough Therapy and Priority Review Designations

The FDA is authorized to designate certain products for expedited 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 are Fast Track
designation, Breakthrough Therapy designation and priority review designation.

Specifically, the FDA may designate a product for Fast Track review if it is intended, whether alone or in
combination with one or more other products, for the treatment of a serious or life-threatening disease or condition, and it
demonstrates the potential to address unmet medical needs for such a disease or condition. For Fast Track products,
sponsors may have greater interactions with the FDA and the FDA may initiate review of sections of a Fast Track product’s
application before the application is complete. This rolling review may be available if the FDA determines, after
preliminary evaluation of clinical data submitted by the sponsor, that a Fast Track product may be effective. The sponsor
must also provide, and the FDA must approve, a schedule for the submission of the remaining information and the sponsor
must pay applicable user fees. However, the FDA’s time period goal for reviewing a Fast Track application does not begin
until the last section of the application is submitted. In addition, the Fast Track designation may be withdrawn by the FDA
if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

Second, a product may be designated as a Breakthrough Therapy if it is intended, either alone or in combination

with one or more other products, to treat a serious or life-threatening disease or condition and preliminary clinical evidence
indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically
significant endpoints, such as substantial treatment effects observed early in clinical development. The FDA may take
certain actions with respect to Breakthrough Therapies, including holding meetings with the sponsor throughout the
development process; providing timely advice to the sponsor regarding development and approval; involving more senior
staff in the review process; assigning a cross-disciplinary project lead for the review team; and taking other steps to design
the clinical trials in an efficient manner.

Third, the FDA may designate a product for priority review if it is a product that treats a serious condition and, if

approved, would provide a significant improvement in safety or effectiveness. The FDA determines, on a case-by-case
basis, whether the proposed product represents a significant improvement 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 adverse reaction, documented enhancement of patient
compliance that is expected to lead to improvement in serious outcomes, and evidence of safety and effectiveness in a new
subpopulation. A priority 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.

Accelerated Approval Pathway

The FDA may grant accelerated approval to a product for a serious or life-threatening condition that provides

meaningful therapeutic advantage to patients over existing treatments based upon a determination that the 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 condition when the product has an effect on an intermediate clinical endpoint that can be measured

34

Table of Contents

earlier than an effect on irreversible morbidity or mortality, or IMM, and that is reasonably likely to predict an effect on
irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the
condition and the availability or lack of alternative treatments. Products 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 product, 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 where
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 clinical benefit of a product.

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 product, even if the effect on the surrogate
or intermediate clinical endpoint occurs rapidly. Thus, accelerated approval has been used extensively in the development
and approval of products 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 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 product’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 IV or post-approval clinical trials to confirm the effect on the clinical endpoint. Failure to conduct required post-
approval studies, or confirm a clinical benefit during post-marketing studies, would allow the FDA to withdraw the product
from the market on an expedited basis. All promotional materials for product candidates approved under accelerated
regulations are subject to prior review by the FDA.

The FDA’s Decision on an NDA

On the basis of the FDA’s evaluation of the NDA and accompanying information, including the results of the

inspection of the manufacturing facilities, the FDA may issue an approval letter or a complete response letter. An approval
letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A
complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing
or information in order for the FDA to reconsider the application. If and when those deficiencies have been addressed to
the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to
reviewing such resubmissions in 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 the FDA approves a product, it may limit the approved indications for use for the product, require that
contraindications, warnings or precautions be included in the product labeling, require that post-approval studies, including
Phase IV clinical trials, be conducted to further assess the drug’s safety after approval, require testing and surveillance
programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or
other risk management mechanisms, including REMS, which can materially affect the potential market and profitability of
the product. The FDA may prevent or limit further marketing of a product based on the results of post-market studies or
surveillance programs. After approval, many types of changes to the approved product, such as adding new indications,
manufacturing changes and additional labeling claims, are subject to further testing requirements and FDA review and
approval.

35

Table of Contents

Post-Approval Requirements

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation
by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling
and distribution, advertising and promotion and reporting of adverse experiences with the product. After approval, most
changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review
and approval. There also are continuing, annual program user fee requirements for any marketed products, as well as new
application fees for supplemental applications with clinical data.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs

are required to register their establishments with the FDA and state agencies, and are subject to periodic unannounced
inspections by the FDA and these state agencies for compliance with cGMP requirements. Changes to the manufacturing
process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also
require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements
upon the NDA holder and any third-party manufacturers that the NDA holder 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. Later discovery of previously
unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing
processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new
safety information; imposition of post-market studies 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:

● restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the

market or voluntary product recalls;

● fines, warning letters or holds on post-approval clinical trials;

● refusal of the FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation

of product approvals;

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

● injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the

market. Drugs generally may be promoted only for the approved indications and in accordance with the provisions of the
approved 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 improperly promoted off-label uses may be subject to significant liability.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing
Act, or 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 pharmaceutical product samples and impose requirements to ensure accountability in distribution.

Companion Diagnostics

We may employ companion diagnostics to help us to more accurately identify patients within a particular subset,

both during our clinical trials and in connection with the commercialization of our product candidates that we are
developing or may in the future develop. Companion diagnostics can identify patients who are most likely to benefit from a
particular therapeutic product; identify patients likely to be at increased risk for serious side effects as a result of treatment
with a particular therapeutic product; or monitor response to treatment with a particular therapeutic product for the purpose
of adjusting treatment to achieve improved safety or effectiveness. Companion diagnostics are regulated as medical devices
by the FDA and, as such, require either clearance or approval prior to commercialization. The level of risk combined with
available controls to mitigate risk determines whether a companion diagnostic device requires Premarket Approval
Application, or PMA, approval or is cleared through the 510(k) premarket notification process. For a novel therapeutic
product for which a companion diagnostic device is essential for the safe and effective use of the product, the companion
diagnostic device should be developed and approved or 510(k)-cleared contemporaneously with the therapeutic. The use of
the companion diagnostic device will be stipulated in the labeling of the therapeutic product.

Abbreviated New Drug Applications for Generic Drugs

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. To
obtain approval of a generic drug, an applicant must submit an abbreviated new drug application, or ANDA, to the agency.
In support of such applications, a generic manufacturer may rely on the preclinical and clinical testing previously
conducted for a drug product previously approved under an NDA, known as the reference-listed drug, or 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. Under the
statute, a generic drug is bioequivalent to a RLD if “the rate and extent of absorption of the drug do not show a significant
difference from the rate and extent of absorption of the listed drug.”

Upon approval of an ANDA, the FDA indicates whether the generic product is “therapeutically equivalent” to the

RLD in its publication “Approved Drug Products with Therapeutic Equivalence Evaluations,” also referred to as the
“Orange Book.” Physicians and pharmacists consider a therapeutic equivalent generic drug to be fully substitutable for the
RLD. In addition, by operation of certain state laws and numerous health insurance programs, the FDA’s designation of
therapeutic equivalence often results in substitution of the generic drug without the knowledge or consent of either the
prescribing physician or patient.

Under the Hatch-Waxman Amendments, the FDA may not approve an ANDA until any applicable period of non-
patent exclusivity for the RLD has expired. The FDCA provides a period of five years of non-patent data exclusivity for a
new drug containing a new chemical entity. For the purposes of this provision, a new chemical entity, or NCE, is a drug
that contains no active moiety that has previously been approved by the FDA in any other NDA. An active moiety is the
molecule or ion responsible for the physiological or pharmacological action of the drug substance. In cases where such
NCE exclusivity has been granted, an ANDA may not be filed with the FDA until the expiration of five years unless the
submission is accompanied by a Paragraph IV certification, which states the proposed generic drug will not infringe the
already approved product’s listed patents or that such patents are invalid or unenforceable, in which case the applicant may
submit its application four years following the original product approval.

The FDCA also provides for a period of three years of exclusivity if the NDA includes reports of one or more new
clinical investigations, other than bioavailability or bioequivalence studies, that were conducted by or for the applicant and
are essential to the approval of the application. This three-year exclusivity period often protects changes to a previously
approved drug product, such as a new dosage form, route of administration, combination or indication. Three-year
exclusivity would be available for a drug product that contains a previously approved active moiety, provided the statutory
requirement for a new clinical investigation is satisfied. Unlike five-year NCE exclusivity, an award of three-year
exclusivity does not block the FDA from accepting ANDAs seeking approval for generic versions of the drug

37

Table of Contents

as of the date of approval of the original drug product. The FDA typically makes decisions about awards of data exclusivity
shortly before a product is approved.

Hatch-Waxman Patent Certification and the 30-Month Stay

Upon approval of an NDA or a supplement thereto, NDA sponsors are required to list with the FDA each patent

with claims that cover the applicant’s product or an approved method of using the product. Each of the patents listed by the
NDA sponsor is published in the Orange Book. When an ANDA applicant files its application with the FDA, the applicant
is required to certify to the FDA concerning any patents listed for the reference product in the Orange Book, except for
patents covering methods of use for which the ANDA applicant is not seeking approval. An applicant who submits a
section 505(b)(2) NDA, which is for new or improved formulations or new uses of previously approved drug products and
where at least one or more of the investigations relied upon by the applicant for approval were not conducted by or for the
applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom the
investigations were conducted, also must certify to the FDA concerning any patents listed for the approved product in the
Orange Book to the same extent that an ANDA applicant would.

Specifically, the applicant must certify with respect to each patent that:

● the required patent information has not been filed;

● the listed patent has expired;

● the listed patent has not expired, but will expire on a particular date and approval is sought after patent

expiration; or

● the listed patent is invalid, unenforceable or will not be infringed by the new product.

A certification that the new product will not infringe the already approved product’s listed patents or that such
patents are invalid or unenforceable is called a Paragraph IV certification. If the applicant does not challenge the listed
patents or indicates that it is not seeking approval of a patented method of use, the ANDA application will not be approved
until all the listed patents claiming the referenced product have expired (other than method of use patents involving
indications for which the ANDA applicant is not seeking approval).

If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice
of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA.
The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV
certification. The filing of a patent infringement lawsuit within 45 days after the receipt of a Paragraph IV certification
automatically prevents the FDA from approving the ANDA until the earlier of 30 months after the receipt of the
Paragraph IV notice, expiration of the patent, or a decision in the infringement case that is favorable to the ANDA
applicant.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, the FDA may designate a drug product as an “orphan drug” if it is intended to treat a
rare disease or condition (generally meaning that it affects fewer than 200,000 individuals in the United States, or more in
cases in which there is no reasonable expectation that the cost of developing and making a drug product available in the
United States for treatment of the disease or condition will be recovered from sales of the product). A company must
request orphan product designation before submitting an NDA. If the request is granted, the FDA will disclose the identity
of the therapeutic agent and its potential use. Orphan product designation does not convey any advantage in or shorten the
duration of the regulatory review and approval process.

If a product with orphan status receives the first FDA approval for the disease or condition for which it has such

designation or for a select indication or use within the rare disease or condition for which it was designated, the product

38

Table of Contents

generally will be receiving orphan product exclusivity. Orphan product exclusivity means that the FDA may not approve
any other applications for the same product for the same indication for seven years, except in certain limited circumstances.
Competitors may receive approval of different products for the indication for which the orphan product has exclusivity and
may obtain approval for the same product but for a different indication. If a drug or drug product designated as an orphan
product ultimately receives marketing approval for an indication broader than what was designated in its orphan product
application, it may not be entitled to exclusivity.

Pediatric Studies and Exclusivity

Under the Pediatric Research Equity Act of 2003, an NDA or supplement thereto must contain data that are
adequate to assess the safety and effectiveness of the drug product for the claimed indications in all relevant pediatric
subpopulations, and to support dosing and administration for each pediatric subpopulation for which the product is safe and
effective. With enactment of the Food and Drug Administration Safety and Innovation Act, or FDASIA, in 2012, sponsors
must also submit pediatric study plans prior to the assessment data. Those plans must contain an outline of the proposed
pediatric study or studies the applicant plans to conduct, including study objectives and design, any deferral or waiver
requests, and other information required by regulation. The applicant, the FDA, and the FDA’s internal review committee
must then review the information submitted, consult with each other, and agree upon a final plan. The FDA or the applicant
may request an amendment to the plan at any time.

The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all

pediatric data until after approval of the product for use in adults, or full or partial waivers from the pediatric data
requirements. Additional requirements and procedures relating to deferral requests and requests for extension of deferrals
are contained in FDASIA. Unless otherwise required by regulation, the pediatric data requirements do not apply to
products with orphan designation.

Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted,
provides for the attachment of an additional six months of marketing protection to the term of any existing regulatory
exclusivity, including the non-patent and orphan exclusivity. This six-month exclusivity may be granted if an NDA sponsor
submits pediatric data that fairly respond to a written request from the FDA for such data. 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.

Patent Term Restoration and Extension

A patent claiming a new drug product may be eligible for a limited patent term extension under the Hatch-

Waxman Amendments, which permits a patent restoration of up to five years for patent term lost during product
development and the FDA regulatory review. The restoration period granted is typically 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
ultimate approval date. Patent term restoration cannot be used to extend the remaining term of a patent past a total of
14 years from the product’s approval date. Only one patent applicable to an approved drug product is eligible for the
extension, and the application for the extension must be submitted prior to the expiration of the patent in question. A patent
that covers multiple drugs for which approval is sought can only be extended in connection with one of the approvals. The
U.S. Patent and Trademark Office reviews and approves the application for any patent term extension or restoration in
consultation with the FDA.

Europe/Rest of World Regulation

In addition to regulations in the United States, there are a variety of regulations in other jurisdictions governing,

among other things, clinical trials, commercial sales and distribution of medicinal products. Even if FDA approval of a
particular product is obtained, it must still obtain the requisite approvals from regulatory authorities in foreign countries
prior to the commencement of clinical trials or marketing of the product in those countries. Certain countries outside of

39

Table of Contents

the United States have a similar process that requires the submission of a clinical trial application much like the IND prior
to the commencement of human clinical trials. Currently in the European Union, for example, a clinical trial application
must be submitted to each country’s national regulatory authority in which the clinical trial is to take place, together with
an independent ethics committee, much like the FDA and IRB, respectively. It is expected, however, that the Clinical Trials
Regulation 536/2014 shall start to apply during the course of 2021. This new Regulation takes direct effect in each
European Union Member State and seeks to simplify and streamline the approval of clinical trials in the European Union,
for example, by allowing the clinical trial sponsor to submit a single application for approval of a clinical trial across the
European Union via a new E.U. Portal. The new Regulation also aims to streamline and simplify the rules on safety
reporting and introduces enhanced transparency requirements, such as mandatory submission of a summary of the clinical
trial results to a new E.U. Database.

Medicinal products can only be commercialized in the European Economic Area, or EEA, after a marketing

authorization, or MA, has been obtained. There are two types of marketing authorizations:

● The centralized MA, which is issued by the European Commission through the Centralized Procedure, based
on the opinion of the Committee for Medicinal Products for Human Use of the European Medicines Agency,
or EMA, and which is valid throughout the entirety of the EEA. The Centralized Procedure is mandatory for
certain types of products, such as biotechnology medicinal products, orphan medicinal products, and
medicinal products indicated for the treatment of AIDS, cancer, neurodegenerative disorders, diabetes, auto-
immune and viral diseases. The Centralized Procedure is optional for products containing an active substance
not authorized in the EEA before May 20, 2004, for products that constitute a significant therapeutic,
scientific or technical innovation or for which a centralized authorization would be in the interest of patients.

● National MAs, which are issued by the competent authorities of the Member States of the EEA and only

cover their respective territory, are available for products not falling within the mandatory scope of the
Centralized Procedure. Where a product has already been authorized for marketing in a Member State of the
EEA, this National MA can be recognized in another Member State through the Mutual Recognition
Procedure. If the product has not received a National MA in any Member State at the time of application, it
can be approved simultaneously in various Member States through the Decentralized Procedure.

Under the above described procedures, before granting the MA, the EMA or the competent authorities of the

Member States of the EEA make an assessment of the risk-benefit balance of the product on the basis of scientific criteria
concerning its quality, safety and efficacy.

The European Union also provides opportunities for market exclusivity. For example, in the European Union,

upon receiving marketing authorization, innovative medicinal products generally receive eight years of data exclusivity and
an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities in the European
Union from referencing the innovator’s data to assess a generic or biosimilar application. During the additional two-year
period of market exclusivity, a generic or biosimilar marketing authorization can be submitted, and the innovator’s data
may be referenced, but no generic or biosimilar product can be marketed until the expiration of the market exclusivity.
Products receiving orphan designation, can receive ten years of market exclusivity, during which time no similar medicinal
product for the same indication may be placed on the market. An orphan product’s market exclusivity may be reduced to
six years if, at the end of the fifth year, it is established that the criteria for orphan drug designation are no longer met, in
other words, when it is shown on the basis of available evidence that the product is sufficiently profitable not to justify
maintenance of market exclusivity. Additionally, marketing authorization may be granted to a similar product for the same
indication at any time if:

● the second applicant can establish that its product, although similar, is safer, more effective or otherwise

clinically superior;

● the applicant consents to a second orphan medicinal product application; or

● the applicant cannot supply sufficient quantities of the orphan medicinal product.

Table of Contents

The criteria for designating an “orphan medicinal product” in the European Union are similar in principle to those
in the United States. Under Article 3 of Regulation (EC) 141/2000, a medicinal product may be designated as orphan if (1)
it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (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. Orphan medicinal products are eligible for
financial incentives such as reduction of fees or fee waivers and scientific assistance for study proposals. The application
for orphan drug designation must be submitted before the application for marketing authorization. The applicant will
receive a fee reduction for the marketing authorization application if the orphan drug designation has been granted, but not
if the designation is still pending at the time the marketing authorization is submitted. Orphan drug designation does not
convey any advantage in, or shorten the duration of, the regulatory review and approval process.

In the European Union, companies developing a new medicinal product must agree to a Paediatric Investigation

Plan, or PIP, with the EMA and must conduct pediatric clinical trials in accordance with that PIP, unless a deferral or
waiver applies, (e.g., because the relevant disease or condition occurs only in adults). The MA application for the product
must include the results of pediatric clinical trials conducted in accordance with the PIP, unless a waiver applies, or a
deferral has been granted, in which case the pediatric clinical trials must be completed at a later date. Products that are
granted a marketing authorization on the basis of the pediatric clinical trials conducted in accordance with the PIP are
eligible for a six month extension of the protection under a supplementary protection certificate (if any is in effect at the
time of approval) or, in the case of orphan medicinal products, a two year extension of the orphan market exclusivity. This
pediatric reward is subject to specific conditions and is not automatically available when data in compliance with the PIP
are developed and submitted. For other countries outside of the European Union, such as certain countries in Eastern
Europe, Latin America or Asia, the requirements governing the conduct of clinical trials, product approval, pricing and
reimbursement vary from country to country. In all cases, the clinical trials are to be conducted in accordance with GCP
and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

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 products will depend, in part, on the extent to which third-party payors, including
government health programs in the United States such as Medicare and Medicaid, commercial health insurers and managed
care organizations, provide coverage, and establish adequate reimbursement levels for, such products. 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 are increasingly
challenging the prices charged, examining the medical necessity, and reviewing the cost-effectiveness of medical products
and services and imposing controls to manage costs. 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 order to secure coverage and reimbursement for any product approved for sale, a company may need to conduct

expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product,
in addition to the costs required to obtain FDA or other comparable regulatory approvals. Nonetheless, product candidates
may not be considered medically necessary or cost effective. Additionally, a payor’s decision to provide coverage for a
drug product does not imply that an adequate reimbursement rate will be approved. Further, no uniform policy for coverage
and reimbursement exists in the United States. Third-party payors often rely upon Medicare coverage policy and payment
limitations in setting their own reimbursement rates, but also have their own methods and approval process apart from
Medicare determinations. Therefore, one payor’s determination to provide coverage for a drug product does not assure that
other payors will also provide coverage for the drug product. Third-party reimbursement may not be sufficient to maintain
price levels high enough to realize an appropriate return on investment in product development.

41

Table of Contents

The containment of healthcare costs also has become a priority of federal, state and foreign governments and the

prices of drugs have been a focus in this effort. Governments have shown significant interest in implementing cost-
containment programs, including price controls, restrictions on 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. Coverage policies and
third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained
for one or more products for which a company or its collaborators receive regulatory approval, less favorable coverage
policies and reimbursement rates may be implemented in the future.

Additionally, we may develop companion diagnostic tests for use with our product candidates. Companion

diagnostic tests require coverage and reimbursement separate and apart from the coverage and reimbursement for their
companion pharmaceutical or biological products. Similar challenges to obtaining coverage and reimbursement, applicable
to pharmaceutical products, will apply to companion diagnostics.

Outside the United States, ensuring adequate coverage and payment for our product candidates will face
challenges. Pricing of prescription pharmaceuticals is subject to governmental control in many countries. Pricing
negotiations with governmental authorities can extend well beyond the receipt of regulatory marketing approval for a
product and may require us to conduct a clinical trial that compares the cost effectiveness of our product candidates or
products to other available therapies. The conduct of such a clinical trial could be expensive and result in delays in our
commercialization efforts.

In the European Union, 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. Some countries may require
the completion of additional studies that compare the cost-effectiveness of a particular drug candidate to currently available
therapies. For example, the European Union provides options for its member states to restrict the range of drug products for
which their national health insurance systems provide reimbursement and to control the prices of medicinal products for
human use. European Union member states may approve a specific price for a drug product or it may instead adopt a
system of direct or indirect controls on the profitability of the company placing the drug product on the market. Other
member states allow companies to fix their own prices for drug products, but monitor and control company profits. The
downward pressure on health care costs in general, particularly prescription drugs, has become intense. As a result,
increasingly high barriers are being erected to the entry of new products. In addition, 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.

Other Healthcare Laws and Regulations

Healthcare providers and third-party payors play a primary role in the recommendation and prescription of drug

products that are granted regulatory approval. Arrangements with providers, consultants, third-party payors and customers
are subject to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain our business
and/or financial arrangements. Such restrictions under applicable federal and state healthcare laws and regulations, include,
without limitation, state and federal anti-kickback, fraud and abuse, false claims, health information privacy and security,
price reporting and physician sunshine laws. Some of our pre-commercial activities are subject to some of these laws.

The federal Health Care Program Anti-Kickback Statute, or Anti-Kickback Statute, prohibits any person or entity,

including a prescription drug manufacturer or a party acting on its behalf, from, among other things, knowingly and
willfully, directly or indirectly, soliciting, receiving, offering, or providing any remuneration that is intended to induce the
referral of business, including the purchase, order or recommendation or arranging of, any good or service for which
payment may be made under a federal healthcare program, such as Medicare or Medicaid. The term “remuneration” has
been broadly interpreted to include anything of value. The Anti-Kickback Statute has been interpreted to apply to
arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, formulary managers, and
beneficiaries on the other. Although there are a number of statutory exceptions and regulatory safe harbors protecting some
common activities from prosecution, the exceptions and safe harbors are drawn narrowly.

42

Table of Contents

Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or
recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the
requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se
illegal under the Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis
based on a cumulative review of all its facts and circumstances. Several courts have interpreted the statute’s intent
requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal
healthcare covered business, the Anti-Kickback Statute has been violated. In addition, a person or entity does not need to
have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Moreover, a
claim including items or services resulting from a violation of the Anti-Kickback Statute constitutes a false or fraudulent
claim for purposes of the federal civil False Claims Act.

The federal civil False Claims Act prohibits, among other things, any person or entity from knowingly presenting,
or causing to be presented, for payment to, or approval by, federal programs, including Medicare and Medicaid, claims for
items or services, including drugs, that are false or fraudulent or not provided as claimed. Persons and entities can be held
liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by, for example,
providing inaccurate billing or coding information to customers or promoting a product off-label. In addition, any of our
future activities relating to the reporting of wholesaler or estimated retail prices for our products, the reporting of prices
used to calculate Medicaid rebate information and other information affecting federal, state and other third-party payor
reimbursement for our products, and the sale and marketing of our products, are subject to scrutiny under this law.
Penalties for federal civil False Claims Act violations may include up to three times the actual damages sustained by the
government, plus significant mandatory civil penalties for each separate false claim, the potential for exclusion from
participation in federal healthcare programs, and, although the federal False Claims Act is a civil statute, False Claims Act
violations may also implicate various federal criminal statutes.

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created new federal criminal

statutes that prohibit among other actions, knowingly and willfully executing, or attempting to execute, a scheme to
defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or
stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and
knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or
fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Like the Anti-
Kickback Statute a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in
order to have committed a violation. Also, many states have similar fraud and abuse statutes or regulations that may be
broader in scope and may apply regardless of payor, in addition to items and services reimbursed under Medicaid and other
state programs. Additionally, to the extent that any of our product candidates, if approved, are sold in a foreign country, we
may be subject to similar foreign laws.

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH,

and their implementing regulations, including the final omnibus rule published on January 25, 2013, mandates, among
other things, the adoption of uniform standards for the electronic exchange of information in common healthcare
transactions, as well as standards relating to the privacy and security of individually identifiable health information, which
require the adoption of administrative, physical and technical safeguards to protect such information. Among other things,
HITECH makes HIPAA’s security standards directly applicable to business associates, defined as independent contractors
or agents of certain healthcare providers, healthcare clearinghouses and health plans, known as covered entities, that create,
receive or obtain protected health information in connection with providing a service for or on behalf of a covered entity.
HITECH also increased the civil and criminal penalties that may be imposed against covered entities and business
associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to
enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, certain state
and foreign laws govern the privacy and security of health information in certain circumstances, some of which are more
stringent than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus
complicating compliance efforts.

The U.S. federal transparency requirements under the Patient Protection and Affordable Care Act, as amended by
the Health Care and Education Reconciliation Act, or collectively, ACA, including the provision commonly referred to as
the Physician Payments Sunshine Act imposed, among other things, new annual reporting requirements for covered

43

Table of Contents

manufacturers for certain payments and other transfers of value provided to physicians, as defined by such law, and 
teaching hospitals, as well as certain ownership and investment interests held by physicians and their immediate family 
members. Beginning in 2022, covered manufacturers also will be required to report information regarding payments and 
other transfers of value provided to, during the previous year,  physician assistants, nurse practitioners, clinical nurse 
specialists, certified nurse anesthetists, anesthesiologist assistants and certified nurse-midwives. 

In addition, we may be subject to certain analogous state and foreign laws of each of the above federal healthcare
laws. In some instances, such laws may be broader in scope than its federal counterpart, such as certain state anti-kickback
and false claims laws, which may apply to claims involving healthcare items or services reimbursed by non-
governmental third party payors, including private insurers. In addition, certain states and local jurisdictions also mandate
implementation of compliance programs, impose restrictions on drug manufacturer marketing practices or require the
tracking and reporting of gifts, compensation or other remuneration to physicians and other healthcare professionals.
Additionally, we may be subject to state and foreign laws governing 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.

Because we intend to commercialize products that could be reimbursed under a federal healthcare program and

other governmental healthcare programs, we intend to develop a comprehensive compliance program that establishes
internal control to facilitate adherence to the rules and program requirements to which we will or may become subject.
Although the development and implementation of compliance programs designed to establish internal control and facilitate
compliance can mitigate the risk of investigation, prosecution, and penalties assessed for violations of these laws, the risks
cannot be entirely eliminated.

If our operations are found to be in violation of any of such laws or any other governmental regulations that apply
to us, we may be subject to penalties, including, without limitation, significant administrative, civil and criminal penalties,
damages, fines, disgorgement, imprisonment, contractual damages, reputational harm, diminished profits and future
earnings, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare
programs, including Medicare and Medicaid, additional reporting requirements and/or oversight if we become subject to a
corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and
individual imprisonment, any of which could adversely affect our ability to operate our business and our financial results.

Healthcare Reform

There have been a number of federal and state proposals during the last few years regarding the pricing of

pharmaceutical and biopharmaceutical products, government control and other changes to the healthcare system in the
United States.

By way of example, the United States and state governments continue to propose and pass legislation designed to

reduce the cost of healthcare. In March 2010, the United States Congress passed the ACA, which, among other things,
includes changes to the coverage and payment for drug products under government health care programs. Among the
provisions of the ACA of importance to our potential drug candidates are:

● an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs

and biologic products, apportioned among these entities according to their market share in certain
government healthcare programs;

● expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer

Medicaid coverage to certain individuals with income at or below 133% of the federal poverty level, thereby
potentially increasing a manufacturer’s Medicaid rebate liability;

● expansion of manufacturers’ rebate liability under the Medicaid Drug Rebate Program by increasing the
minimum rebate for both branded and generic drugs and revising the definition of “average manufacturer
price,” or AMP, for calculating and reporting Medicaid drug rebates on outpatient prescription drug prices;

44

Table of Contents

● 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;

● expansion of the types of entities eligible for the 340B drug discount program;

● establishment of the Medicare Part D coverage gap discount program by requiring manufacturers to now
provide a 70% point-of-sale-discount off the negotiated price of applicable brand drugs to eligible
beneficiaries during their coverage gap period as a condition for the manufacturers’ outpatient drugs to be
covered under Medicare Part D;

● a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct

comparative clinical effectiveness research, along with funding for such research; and

● establishment of a Center for Medicare and Medicaid Innovation at the Centers for Medicare & Medicaid
Services, or CMS, an agency within the U.S. Department of Health and Human Services, HHS to test
innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially
including prescription drug spending.

There remain judicial and Congressional challenges to certain aspects of the ACA. President Trump signed several

Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise
circumvent some of the requirements for health insurance mandated by the ACA. While Congress has not passed
comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA such as removing or
delaying penalties, starting January 1, 2019, for not complying with the Affordable Care Act’s individual mandate to carry
health insurance, eliminating the implementation of certain ACA-mandated fees, and increasing the point-of-sale discount
that is owed by pharmaceutical manufacturers who participate in Medicare Part D. On December 14, 2018, a Texas U.S. 
District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed 
by Congress as part of the Tax Act.  Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit 
upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District 
Court to determine whether the remaining provisions of the ACA are invalid as well. The U.S. Supreme Court is currently 
reviewing this case, but it is unknown when a decision will be reached. Although the U.S. Supreme Court has not yet ruled
on the constitutionality of the ACA, on January 28, 2021, President Biden issued an executive order to initiate a special
enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage
through the ACA marketplace. The executive order also instructs certain governmental agencies to review and reconsider
their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid
demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers
to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how the U.S. Supreme Court
ruling, other such litigation, and the healthcare reform measures of the Biden administration will impact the ACA and our
business.

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For
example, in August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions
by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at
least $1.2 trillion for the years 2012 through 2021, was unable to reach required goals, thereby triggering the legislation’s
automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to
providers of 2% per fiscal year, which went into effect in April 2013 and, due to legislative amendments, will remain in
effect through 2030 unless additional Congressional action is taken. However, pursuant to certain COVID-19 relief
legislation, these Medicare sequester reductions have been suspended from May 1, 2020 through March 31, 2021. In
January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things,
further reduced Medicare payments to several providers, including hospitals, imaging centers and cancer treatment centers,
and increased the statute of limitations period for the government to recover overpayments to providers from three to five
years.

Also, there has been heightened governmental scrutiny recently over the manner in which drug manufacturers set

prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted

45

Table of Contents

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. At the federal level, the former Trump administration used several means to propose or 
implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. For 
example, on July 24, 2020 and September 13, 2020, former President Trump signed several Executive Orders aimed at 
lowering drug pricing that seek to implement several of the administration's proposals. In response, the FDA released a 
final rule on September 24, 2020, which went into effect on November 30, 2020, providing guidance for states to build and 
submit importation plans for drugs from Canada. Further, on November 20, 2020 CMS issued an Interim Final Rule 
implementing the Most Favored Nation, or MFN, Model  under which  Medicare Part B reimbursement rates will be 
calculated for certain drugs and biologicals based on the lowest price drug manufacturers receive in Organization for 
Economic Cooperation and Development, or OECD, countries with a similar gross domestic product per capita.  The MFN 
Model regulations mandate participation by identified Part B providers and will apply in all U.S. states and territories for a 
seven-year period and was scheduled to begin on January 1, 2021 and end on December 31, 2027.   On December 28, 
2020, the U.S. District Court in Northern California issued a nationwide preliminary injunction against implementation of 
the interim final rule. Additionally, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for 
price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy 
benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the 
Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new 
safe harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements 
between pharmacy benefit managers and manufacturers the implementation of which have also been delayed pending 
review by the Biden administration until March 22, 2021. However, it is unclear whether the Biden administration will 
work to reverse these measures or pursue similar policy initiatives.  

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and 

state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare.  Further, 
it is possible that additional governmental action is taken in response to the COVID-19 pandemic. 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.

Brexit and the Regulatory Framework in the United Kingdom

On June 23, 2016, the electorate in the United Kingdom voted in favor of leaving the European Union, commonly 
referred to as Brexit, and the United Kingdom officially withdrew from the European Union on January 31, 2020.  Pursuant 
to the formal withdrawal arrangements agreed between the United Kingdom and the European Union, the United Kingdom 
was subject to a transition period until December 31, 2020, or the Transition Period, during which European Union rules 
continued to apply.  A trade and cooperation agreement, or the Trade and Cooperation Agreement, which outlines the 
future trading relationship between the United Kingdom and the European Union, was agreed upon in December 2020.

Great Britain is no longer covered by the European Union’s procedures for the grant of marketing authorizations , 

though Northern Ireland will be covered by the centralized authorization procedure and can be covered under the 
decentralized or mutual recognition procedures. A separate marketing authorization will be required to market drugs in 
Great Britain.  However, for two years from January 1, 2021, the United Kingdom’s regulator, the Medicines & Healthcare 
products Regulatory Agency, or MHRA, may adopt decisions taken by the European Commission on the approval of new 
marketing authorizations through the centralized procedure, and the MHRA will have regard to marketing authorizations 
approved in a country in the EEA (although in both cases a marketing authorization will only be granted if any Great 
Britain-specific requirements are met). Various national procedures are now available to place a drug on the market in the 
United Kingdom, Great Britain or Northern Ireland, with the main national procedure having a maximum timeframe of 150 
days (excluding time taken to provide any further information or data required).  The data exclusivity periods in the United 
Kingdom are currently in line with those in the European Union, but the Trade and Cooperation Agreement provides that 
the periods for both data and market exclusivity are to be determined by domestic law, and so there could be divergence in 
the future. It is currently unclear whether the MHRA in the United Kingdom is sufficiently prepared to handle the 
increased volume of marketing authorization applications that it is likely to receive.

Orphan designation in Great Britain following Brexit is essentially identical to the position in the European 

Union, but it is based on the prevalence of the condition in Great Britain.  It is therefore possible that conditions that are 
currently designated as orphan conditions in Great Britain will no longer be and that conditions that are not currently 
designated as orphan conditions in the European Union will be designated as such in Great Britain. 

The European Union’s regulatory environment for clinical trials is being harmonized as part of the Clinical Trial

Regulations, which are due to enter into full effect at the end of 2021, but it is currently unclear as to what extent the
United Kingdom will seek to align its regulations with the European Union.

Employees and Human Capital

As of December 31, 2020, we had 87 full-time or part-time employees, including 41 with M.D. or Ph.D. degrees.

Of these employees, 68 employees are engaged in research and development activities and 19 employees are engaged in
general and administrative activities. Our employees are primarily based at the locations of our office and laboratory
facilities: 52 are located in the U.K. and 35 are located in Massachusetts, U.S. None of our employees are represented by
labor unions or covered by collective bargaining agreements. We consider the relationship with our employees to be good.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and

integrating our existing and additional employees to support the continued growth of our company and progress the
development of our product candidates. The principal purposes of our equity incentive plans are to attract, retain and
motivate selected employees, consultants and directors through the granting of equity-based compensation awards.

Corporate Information

In 2009, we were incorporated as a limited liability company under the laws of England and Wales. In 2017, we

effected a reorganization to create a new holding company which, in connection with our IPO, was re-registered as a public
limited company named Bicycle Therapeutics plc. Bicycle Therapeutics plc is the parent company of three wholly owned
subsidiaries, two of which are based in Cambridge, England and one of which has its principal office in Lexington,
Massachusetts, that will carry on our business.

The English subsidiaries are BicycleTx Limited and BicycleRD Limited, and the U.S. subsidiary is Bicycle

Item 1A Risk Factors.

Risk Factors

Our operations and financial results are subject to various risks and uncertainties, including those described 
below.  The following information about these risks and uncertainties, together with the other information appearing 
elsewhere in this Annual Report on Form 10-K, including our consolidated financial statements and related notes thereto, 
should be carefully considered before a decision to invest in our ADSs. The occurrence of any of the following risks could 
have a material adverse effect on our business, financial condition, results of operations and future growth prospects or 
cause our actual results to differ materially from those contained in forward-looking statements we have made in this 
report and those we may make from time to time. Additional risks that are currently unknown to us or that we currently 
believe to be immaterial may also impair our business. In these circumstances, the market price of our ADSs could decline 
and holders of our ADSs may lose all or part of their investment. We cannot provide assurance that any of the events 
discussed below will not occur.

Risks Related to Our Financial Position and Need for Additional Capital

We have a history of significant operating losses and expect to incur significant and increasing losses for the
foreseeable future, and we may never achieve or maintain profitability.

We do not expect to generate revenue or profitability that is necessary to finance our operations in the short term.  

Since inception, we have incurred recurring losses, including losses of $51.0 million, $30.6 million and $21.8 million for
the years ended December 31, 2020, 2019 and 2018, respectively.  In addition, our accumulated deficit as of December 31, 
2020 was $151.6 million. To date, we have not commercialized any products or generated any revenues from the sale of 
products, and absent the realization of sufficient revenues from product sales, we may never attain profitability in the 
future.  We have devoted substantially all of our financial resources and efforts to research and development, including 
preclinical studies and our clinical trials.  Our net losses may fluctuate significantly from quarter to quarter and year to 
year. Net losses and negative cash flows have had, and will continue to have, an adverse effect on our shareholders’ equity
(deficit) and working capital.

We anticipate that our expenses will increase substantially if and as we:

● continue to develop and conduct clinical trials with respect to our BTC and TICATM programs and our other

pipeline programs;

● initiate and continue research, preclinical and clinical development efforts for any future product candidates;

● seek to discover and develop additional product candidates and further expand our clinical product pipeline;

● seek marketing and regulatory approvals for any product candidates that successfully complete clinical trials;

● require the manufacture of larger quantities of product candidates for clinical development and, potentially,

commercialization;

● maintain, expand and protect our intellectual property portfolio;

● expand our research and development infrastructure, including hiring and retaining additional personnel, such

as clinical, quality control and scientific personnel;

48

Table of Contents

● establish sales, marketing, distribution and other commercial infrastructure in the future to commercialize

products for which we obtain marketing approval, if any;

● add operational, financial and management information systems and personnel, including personnel to

support our product development and commercialization and help us comply with our obligations as a public
company; and

● add equipment and physical infrastructure to support our research and development.

Our ability to become and remain profitable depends on our ability to generate revenue.  Generating product 

revenue will depend on our or any of our collaborators’ ability to obtain marketing approval for, and successfully 
commercialize, one or more of our product candidates.  Successful commercialization will require achievement of key 
milestones, including completing clinical trials of our product candidates, obtaining marketing approval for these product 
candidates, manufacturing, marketing and selling those products for which we, or any of our collaborators, may obtain 
marketing approval, satisfying any post-marketing requirements and obtaining reimbursement for our products from 
private insurance or government payors.  Because of the uncertainties and risks associated with these activities, we are 
unable to accurately predict the timing and amount of revenues, and if or when we might achieve profitability.  We and any 
collaborators may never succeed in these activities and, even if we do, or any collaborators do, we may never generate 
revenues that are large enough for us 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 revenue to date has been primarily generated from our research collaborations with Genentech, AstraZeneca 

AB, or AstraZeneca, Sanofi (formerly Bioverativ Inc.), Oxurion NV (formerly ThromboGenics NV), or Oxurion, and 
Dementia Discovery Fund, or DDF.  There can be no assurance that we will generate revenue from our collaborations in 
the future.

Our failure to become and remain profitable would depress the market price of our ADSs and could impair our 
ability to raise capital, expand our business, diversify our product offerings or continue our operations.  If we continue to 
suffer losses, investors may not receive any return on their investment and may lose their entire investment.

Our limited operating history may make it difficult for holders of our ADSs or ordinary shares to evaluate the success of
our business to date and to assess our future viability.

Our business commenced operations in 2009. Our operations to date have been limited to financing and staffing 

our company, developing our technology, conducting preclinical research and early-stage clinical trials for our product 
candidates and pursuing strategic collaborations to advance our product candidates. We have not yet demonstrated an 
ability to successfully conduct late-stage clinical trials, obtain marketing approvals, manufacture a commercial-scale 
product, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for 
successful product commercialization. Accordingly, any current or prospective holder of our ADSs or ordinary shares 
should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by 
companies in the early stages of development, especially clinical-stage biopharmaceutical companies such as ours, all of 
which delays and difficulties may be exacerbated as a result of the ongoing COVID-19 pandemic.  Any predictions made 
about our future success or viability may not be as accurate as they would be if we had a longer operating history or a 
history of successfully developing and commercializing pharmaceutical products.

We may encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors
in achieving our business objectives. We will eventually need to transition from a company with a development focus to a
company capable of supporting commercial activities. We may not be successful in such a transition.

We expect our financial condition and operating results to continue to fluctuate significantly from quarter to

quarter and year to year due to a variety of factors, many of which are beyond our control and reliance should not be made
upon the results of any quarterly or annual periods as indications of future operating performance.

49

Table of Contents

We may need substantial additional funding, and if we are unable to raise capital when needed, we could be forced to
delay, reduce or eliminate our product discovery and development programs or commercialization efforts.

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-

consuming, expensive and uncertain process that takes years to complete. We expect our expenses to increase in connection 
with our ongoing activities, particularly as we initiate new clinical trials of, initiate new research and preclinical 
development efforts for and seek marketing approval for, our current product candidates or any future product candidates. 
In addition, if we obtain marketing approval for any of our product candidates, we may incur significant commercialization 
expenses related to product sales, marketing, manufacturing and distribution to the extent that such sales, marketing, 
manufacturing and distribution are not the responsibility of a collaborator.  Furthermore, we expect to incur significant 
additional costs associated with operating as a public company.  Accordingly, we will need to obtain substantial additional 
funding in connection with our continuing operations.  If we are unable to raise capital when needed or on attractive terms, 
we may be forced to delay, reduce or eliminate our research and development programs or any future commercialization 
efforts.

We will be required to expend significant funds in order to advance the development of the product candidates in 

our pipeline, as well as other product candidates we may seek to develop.  In addition, while we may seek one or more 
collaborators for future development of our product candidates, we may not be able to enter into a collaboration for any of 
our product candidates for such indications on suitable terms, on a timely basis or at all. In any event, our existing cash will 
not be sufficient to fund all of the efforts that we plan to undertake or to fund the completion of development of any of our 
product candidates. Accordingly, we will be required to obtain further funding through public or private equity offerings, 
debt financings, collaborations and licensing arrangements or other sources.  We do not have any committed external 
source of funds. Adequate additional financing may not be available to us on acceptable terms, or at all. Our failure 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 believe that our existing cash of $136.0 million as of December 31, 2020, will enable us to fund our operating
expenses and capital expenditure requirements for at least 12 months from the date of filing of this Annual Report on Form 
10-K. Our estimate may prove to be wrong, and we could use our available capital resources sooner than we currently 
expect.  Further, changing circumstances, some of which may be beyond our control, including the unanticipated impacts 
of the ongoing COVID-19 pandemic, could cause us to consume capital significantly faster than we currently anticipate, 
and we may need to seek additional funds sooner than planned. Our future funding requirements, both short-term and long-
term, will depend on many factors, including:

● the scope, progress, timing, costs and results of clinical trials of, and research and preclinical development

efforts for, our current and future product candidates;

● our ability to enter into, and the terms and timing of, any collaborations, licensing or other arrangements;

● our ability to identify one or more future product candidates for our pipeline;

● the number of future product candidates that we pursue and their development requirements;

● the outcome, timing and costs of seeking regulatory approvals;

● the costs of commercialization activities for any of our product candidates that receive marketing approval to

the extent such costs are not the responsibility of any collaborators, including the costs and timing of
establishing product sales, marketing, distribution and manufacturing capabilities;

● subject to receipt of marketing approval, revenue, if any, received from commercial sales of our current and

future product candidates;

● our headcount growth and associated costs as we expand our research and development and establish a

commercial infrastructure;

50

Table of Contents

● the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual

property rights including enforcing and defending intellectual property related claims; and

● the costs of operating as a public company.

The spread of COVID-19, which continues to cause a broad impact globally, may materially affect us

economically. While the long-term economic impact of the pandemic is difficult to assess or predict, it has already
significantly disrupted global financial markets, reducing our ability to access capital, which could in the future negatively
affect our liquidity.

Raising additional capital may cause dilution to our existing shareholders or holders of our ADSs, restrict our
operations or cause us to relinquish valuable rights.

We may seek additional capital through a combination of public and private equity offerings, debt financings, 

strategic partnerships and alliances, licensing arrangements or monetization transactions. To the extent that we raise 
additional capital through the sale of equity, convertible debt securities or other equity-based derivative securities, the 
ownership interest of existing holders of our ADSs or ordinary shares will be diluted and the terms may include liquidation 
or other preferences that adversely affect existing holders’ rights. Any indebtedness we incur would result in increased 
fixed payment obligations and could involve restrictive covenants, such as limitations on our ability to incur additional 
debt, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could 
adversely impact our ability to conduct our business. Furthermore, the issuance of additional securities, whether equity or 
debt, by us, or the possibility of such issuance, may cause the market price of our ADSs to decline and existing 
shareholders may not agree with our financing plans or the terms of such financings. If we raise additional funds through 
strategic partnerships and alliances, licensing arrangements or monetization transactions with third parties, we may have to 
relinquish valuable rights to our technologies, or our product candidates, or grant licenses on terms unfavorable to us. 
Adequate additional financing may not be available to us on acceptable terms, or at all.  If we are unable to raise additional 
funds when needed, we may be required to delay, limit, reduce or terminate our product development or future 
commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to 
develop and market ourselves.

Our failure to comply with the covenants or payment obligations under our existing term loan facility with Hercules
could result in an event of default, which may result in increased interest charges, acceleration of our repayment
obligations or other actions by Hercules, any of which could negatively impact our business, financial condition and
results of operations.

 We are party to a secured term loan facility with Hercules.  As of December 31, 2020, our outstanding 
borrowings under this facility totaled $15.0 million. Subject to satisfaction of customary conditions, we may borrow an 
additional term loan of up to $15.0 million available through March 15, 2021, and subject to our achievement of certain 
performance milestones and satisfaction of customary conditions we may borrow an additional term loan of $10.0 million 
through March 15, 2022. In connection with the Loan Agreement with Hercules, or the Loan Agreement, we granted 
Hercules a security interest in substantially all of our personal property and other assets, other than our intellectual 
property. The Loan Agreement contains customary affirmative and restrictive covenants and representations and 
warranties, including a covenant against the occurrence of a change in control (as defined by the Loan Agreement), 
financial reporting obligations, and certain limitations on indebtedness, liens (including a negative pledge on intellectual 
property and other assets), investments, distributions (including dividends), collateral, investments, transfers, mergers or 
acquisitions, taxes, corporate changes, and deposit accounts. The Loan Agreement also includes customary events of 
default, including payment defaults, breaches of covenants following any applicable cure period, the occurrence of certain 
events that could reasonably be expected to have a material adverse effect as set forth in the Loan Agreement, cross 
acceleration to third-party indebtedness and certain events relating to bankruptcy or insolvency. Upon the occurrence of an 
event of default, a default interest rate of an additional 5.0% may be applied to the outstanding principal balance, and 
Hercules may declare all outstanding obligations immediately due and payable and take such other actions as set forth in 
the Loan Agreement, including proceeding against the collateral securing such indebtedness.  

51

Table of Contents

Such increased interest charges, accelerated repayment, proceedings against the collateral or other actions may have a 
negative impact on our business, financial condition and results of operations.  

Our existing and any future indebtedness may limit our cash flow available to invest in the ongoing needs of our
business.

As of December 31, 2020, we had $15.0 million of borrowings outstanding under the Loan Agreement with

Hercules, and we may borrow up to an additional $25.0 million in the aggregate under the Loan Agreement, subject to
certain conditions. We could also in the future incur additional indebtedness pursuant to additional loan agreements.

Our debt combined with our other financial obligations and contractual commitments could have significant adverse

consequences, including:

● requiring us to dedicate cash flow from operations or cash on hand to the payment of interest on, and principal of,

our debt, which will reduce the amounts available to fund working capital, capital expenditures, product
development efforts and other general corporate purposes;

● increasing our vulnerability to adverse changes in general economic, industry and market conditions;

● subjecting us to restrictive covenants that may reduce our ability to take certain corporate actions or obtain further

debt or equity financing;

● limiting our flexibility in planning for, or reacting to, changes in our business and our industry; and

● placing us at a competitive disadvantage compared to our competitors that have less debt or better debt servicing

options.

We intend to satisfy our current and future debt service obligations with our existing cash and funds from external
sources. Nonetheless, we may not have sufficient funds or may be unable to arrange for additional financing to pay the
amounts due under our existing or any future debt facility. Funds from external sources may not be available on acceptable
terms, if at all. In addition, a failure to comply with the covenants under the Loan Agreement or any future loan agreements
we may enter into could result in an event of default and acceleration of amounts due. If an event of default occurs and the
lenders accelerate the amounts due under such loan agreements, we may not be able to make accelerated payments, and
such lenders could seek to enforce security interests in the collateral securing such indebtedness.

Risks Related to the Discovery, Development and Regulatory Approval of Our Product Candidates

We are substantially dependent on the success of our internal development programs and of our product candidates
from our BTC and tumor-targeted immune cell agonist programs which may not successfully complete clinical trials,
receive regulatory approval or be successfully commercialized.

Our future success will depend heavily on the success of our internal development programs and of product

candidates from our BTC and tumor-targeted immune cell agonist programs.

Within our BTC program, we are investigating BT1718 for safety, tolerability and efficacy in an ongoing Phase 
I/IIa clinical trial in collaboration with the Cancer Research UK Centre for Drug Development, or Cancer Research UK.  
Upon the completion of the Phase I/IIa clinical trial for BT1718, we have the right to obtain a license to the results of the 
clinical trial from Cancer Research UK upon the payment of a milestone, in cash and ordinary shares with a combined 
value in a mid-six digit dollar amount.  If we do not exercise our right to obtain a license to the results of the clinical trial 
or we fail to obtain a license, our ability to continue development of BT1718 would be negatively impacted.  BT1718 is 
designed to target tumors that express MT1-MMP.  In addition, we are evaluating BT5528, a second-generation BTC that 
targets Ephrin type-A receptor 2, or EphA2 and carries a monomethyl auristatin E, or MMAE cytotoxin payload, in an 
ongoing, company-sponsored Phase I/II clinical trial to assess safety, pharmacokinetics and preliminary clinical activity in 
patients with advanced malignancies associated with EphA2 expression as a monotherapy and in combination 

52

Table of Contents

with nivolumab, and BT8009, a second-generation BTC targeting Nectin-4, in a company sponsored Phase I/II clinical 
trial. We are also developing BT7480, which is a TICA targeting Nectin-4 and agonizing CD137, for oncology indications.  
These target proteins have an established role in cell invasion and metastasis and are overexpressed in many solid tumors. 
There can be no assurance our BTCs or TICAs will ever demonstrate evidence of safety or effectiveness for any use or 
receive regulatory approval in the United States, the European Union, or any other country in any indication.  Even if 
clinical trials show positive results, there can be no assurance that the U.S. Food and Drug Administration, or FDA, in the 
United States, European Commission, whose decision is based on a recommendation from the European Medicines 
Agency, or EMA, in Europe or similar regulatory authorities will approve our BTCs or any of our other product candidates 
for any given indication for several potential reasons, including the failure to follow Good Clinical Practice, or GCP, a 
negative assessment of the risks and benefits, insufficient product quality control and standardization, failure to have Good 
Manufacturing Practices, or GMP, compliant manufacturing facilities, or the failure to agree with regulatory authorities on 
clinical endpoints.

Our ability to successfully commercialize our BTCs, tumor-targeted immune cell agonists, and our other product

candidates will depend on, among other things, our ability to:

● successfully complete preclinical studies and clinical trials, which may be delayed;

● receive regulatory approvals from the FDA, the European Commission based on a recommendation from the

EMA and other similar regulatory authorities;

● establish and maintain collaborations with third parties for the development and/or commercialization of our
product candidates, or otherwise build and maintain strong development, sales, distribution and marketing
capabilities that are sufficient to develop products and launch commercial sales of any approved products;

● obtain coverage and adequate reimbursement from payors such as government health care systems and

insurance companies and achieve commercially attractive levels of pricing;

● secure acceptance of our product candidates from physicians, health care payors, patients and the medical

community;

● produce, through a validated process, in manufacturing facilities inspected and approved by regulatory

authorities, including the FDA, sufficiently large quantities of our product candidates to permit successful
commercialization;

● manage our spending as expenses increase due to clinical trials and commercialization; and

● obtain and enforce sufficient intellectual property rights for any approved products and product candidates

and maintain freedom to operate for such products with respect to the intellectual property rights of third
parties.

Of the large number of drugs in development in the pharmaceutical industry, only a small percentage result in the 

submission of a new drug application, or NDA, to the FDA and even fewer are approved for commercialization.  
Furthermore, even if we do receive regulatory approval to market our product candidates, any such approval may be 
subject to limitations on the indicated uses or patient populations for which we may market the product.  Accordingly, even 
if we are able to obtain the requisite financing to continue to fund our development programs, we cannot provide assurance 
that our product candidates will be successfully developed or commercialized.  If we are unable to develop, or obtain 
regulatory approval for, or, if approved, to successfully commercialize our product candidates, we may not be able to 
generate sufficient revenue to continue our business.

53

Table of Contents

We are at a very early stage in our development efforts, our product candidates and those of our collaborators represent
a new category of medicines and may be subject to heightened regulatory scrutiny until they are established as a
therapeutic modality.

Bicycles represent a new therapeutic modality of peptide compounds intended to combine targeting abilities of 

antibodies with performance of small molecules.  Our product candidates may not demonstrate in patients any or all of the 
pharmacological benefits we believe they may possess.  We have not yet succeeded and may never succeed in 
demonstrating efficacy and safety for these or any other product candidates in clinical trials or in obtaining marketing 
approval thereafter.

Regulatory authorities have limited experience with Bicycles and may require evidence of safety and efficacy that 

goes beyond what we and our collaborators have included in our development plans.  In such a case, development of
 Bicycle product candidates may be more costly or time-consuming than expected, and our candidate products and those of
our collaboration partners may not prove to be viable.

If we are unsuccessful in our development efforts, we may not be able to advance the development of our product

candidates, commercialize products, raise capital, expand our business or continue our operations.

Our product candidates and those of our collaborators will need to undergo preclinical and clinical trials that are time
consuming and expensive, the outcomes of which are unpredictable, and for which there is a high risk of failure.  If
preclinical or clinical trials of our or their product candidates fail to satisfactorily demonstrate safety and efficacy to the
FDA, the EMA and any other comparable regulatory authority, additional costs may be incurred or delays experienced
in completing, the development of these product candidates, or their development may be abandoned.

The FDA in the United States, the European Commission based on a recommendation from the EMA, or other 

European regulatory authorities, in the European Union and the European Economic Area, or EEA, and any other 
comparable regulatory authorities in other jurisdictions must approve new product candidates before they can be marketed, 
promoted or sold in those territories.  We have not previously submitted an NDA to the FDA or similar drug approval 
filings to comparable foreign regulatory authorities for any of our product candidates.  We must provide these regulatory 
authorities with data from preclinical studies and clinical trials that demonstrate that our product candidates are safe and 
effective for a specific indication before they can be approved for commercial distribution.  We cannot be certain that our 
clinical trials for our product candidates will be successful or that any of our other product candidates will receive approval 
from the FDA, the European Commission based on a recommendation from the EMA or any other comparable regulatory 
authority.

Preclinical studies and clinical trials are long, expensive and unpredictable processes that can be subject to 
extensive delays.  We cannot guarantee that any clinical trials will be conducted as planned or completed on schedule, if at 
all.  It may take several years and require significant expenditures to complete the preclinical studies and clinical trials 
necessary to commercialize a product candidate, and delays or failure are inherently unpredictable and can occur at any 
stage.  The ongoing COVID-19 pandemic, including many jurisdictions’ shelter-in-place, stay-at-home and similar 
restrictions, may also impact our and our collaboration partners’ abilities to activate trial sites or enroll patients in clinical 
trials or to otherwise advance those clinical trials.  Although some jurisdictions have relaxed such restrictions and 
vaccination against COVID-19 has commenced, previously relaxed restrictions may be re-instituted, and vaccination is not 
yet widespread on a global basis.  Ongoing, new or re-imposed COVID-19-related shelter-in-place, stay-at-home and 
similar restrictions, site closures, travel limitations and supply chain interruptions, or infection of site personnel or trial 
patients with COVID-19, may also reduce our or our collaboration partners’ abilities to administer the investigational 
product to enrolled patients, present difficulties for enrolled patients to adhere to protocol-mandated visits and 
laboratory/diagnostic testing, increase the possibility of patient dropouts, or impact our and our suppliers’ abilities to 
provide investigational product to trial sites, all of which could negatively impact the data we are able to obtain from our 
clinical trials and complicate regulatory review.  

We may also be required to conduct additional clinical trials or other testing of our product candidates beyond the 

trials and testing that we contemplate, which may lead to us incurring additional unplanned costs or result in delays in 
clinical development.  In addition, we may be required to redesign or otherwise modify our plans with respect to an 

54

Table of Contents

ongoing or planned clinical trial, and changing the design of a clinical trial can be expensive and time consuming.  An 
unfavorable outcome in one or more trials would be a major setback for our product candidates and for us.  An unfavorable 
outcome in one or more trials may require us to delay, reduce the scope of or eliminate one or more product development 
programs, which could have a material adverse effect on our business, financial position, results of operations and future 
growth prospects.

Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also 
ultimately lead to the denial of marketing approval for our product candidates.  The FDA, EMA or any other comparable 
regulatory authority may disagree with our clinical trial design and our interpretation of data from clinical trials, or may 
change the requirements for approval even after it has reviewed and commented on the design for our clinical trials.

In connection with clinical trials of our product candidates, we face a number of risks, including risks that:

● a product candidate is ineffective or inferior to existing approved products for the same indications;

● a product candidate causes or is associated with unacceptable toxicity or has unacceptable side effects;

● patients may die or suffer adverse effects for reasons that may or may not be related to the product candidate

being tested;

● the results may not confirm the positive results of earlier trials;

● the results may not meet the level of statistical significance required by the FDA, the EMA or other relevant
regulatory agencies to establish the safety and efficacy of our product candidates for continued trial or
marketing approval; and

● our collaborators may be unable or unwilling to perform under their contracts.

Furthermore, we sometimes estimate for planning purposes the timing of the accomplishment of various scientific, 

clinical, regulatory and other product development objectives.  These milestones may include our expectations regarding 
the commencement or completion of scientific studies, clinical trials, the submission of regulatory filings or 
commercialization objectives.  From time to time, we may publicly announce the expected timing of some of these 
milestones, such as the completion of an ongoing clinical trial, the initiation of other clinical programs, the receipt of 
marketing approval or a commercial launch of a product.  The achievement of many of these milestones may be outside of 
our control.  All of these milestones are based on a variety of assumptions, which may cause the timing of achievement of 
the milestones to vary considerably from our estimates.  If we fail to achieve milestones in the timeframes we expect, 
including as a result of the ongoing COVID-19 pandemic, the commercialization of our product candidates may be 
delayed, we may not be entitled to receive certain contractual payments, which could have a material adverse effect on our 
business, financial position, results of operations and future growth prospects.

We may find it difficult to enroll patients in our clinical trials, which could delay or prevent us from proceeding with
clinical trials of our product candidates.

Identifying and qualifying patients to participate in clinical trials of our product candidates is critical to our 

success.  The timing of our clinical trials depends on our ability to recruit patients to participate as well as the completion 
of required follow-up periods.  Patients may be unwilling to participate in our clinical trials because of negative publicity 
from adverse events related to novel therapeutic approaches, competitive clinical trials for similar patient populations, the 
existence of current treatments or for other reasons.  Enrollment risks are heightened with respect to certain indications that 
we may target for one or more of our product candidates that may be rare diseases, which may limit the pool of patients 
that may be enrolled in our planned clinical trials.  The timeline for recruiting patients, conducting trials and obtaining 
regulatory approval of our product candidates may be delayed, which could result in increased costs, delays in advancing 
our product candidates, delays in testing the effectiveness of our product candidates or termination of the clinical trials 
altogether.

55

Table of Contents

In addition, our ability to conduct clinical trials has been and may continue to be affected by the ongoing COVID-
19 pandemic. For example, all clinical sites for the Phase I/IIa trial of BT1718 being conducted by Cancer Research UK in 
the United Kingdom temporarily paused enrollment of new patients due to the ongoing COVID-19 pandemic during the 
first half of 2020. While the pause in enrollment was lifted during the second quarter of 2020 and patient enrollment in the 
Phase IIa portion of the clinical trial is underway, changes in circumstances related to the ongoing pandemic could result in 
future pauses in or other impacts on enrollment.  Further clinical site initiation and patient enrollment may be delayed due 
to prioritization of hospital resources toward the COVID-19 pandemic, including with respect to vaccination efforts. Some 
key clinical trial activities, such as clinical trial site monitoring, may also be impacted due to limitations on travel, 
quarantines or social distancing protocols imposed or recommended by federal or state governments, employers and others 
in connection with the ongoing COVID-19 pandemic. Some patients may not be able to comply with clinical trial protocols 
if quarantines impede patient movement or interrupt healthcare services. Similarly, our ability to recruit and retain patients 
and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19, may 
adversely impact our future clinical trial operations.

We may not be able to identify, recruit and enroll a sufficient number of patients, or those with the required or 

desired characteristics, to complete our clinical trials in a timely manner.  For example, due to the nature of the indications 
that we are initially targeting, patients with advanced disease progression may not be suitable candidates for treatment with 
our product candidates and may be ineligible for enrollment in our clinical trials.  Therefore, early diagnosis in patients 
with our target diseases is critical to our success.  Patient enrollment and trial completion is affected by factors including 
the:

● size of the patient population and process for identifying subjects;

● design of the trial protocol;

● eligibility and exclusion criteria;

● safety profile, to date, of the product candidate under study;

● perceived risks and benefits of the product candidate under study;

● perceived risks and benefits of our approach to treatment of diseases;

● availability of competing therapies and clinical trials;

● severity of the disease under investigation;

● degree of progression of the subject’s disease at the time of enrollment;

● proximity and availability of clinical trial sites for prospective subjects;

● ability to obtain and maintain subject consent;

● risk that enrolled subjects will drop out before completion of the trial;

● patient referral practices of physicians; and

● ability to monitor subjects adequately during and after treatment.

In addition, clinical testing of BT1718, BT5528 and BT8009 is currently taking place outside of the United States.

Our ability to successfully initiate, enroll and complete a clinical trial in any foreign country is subject to numerous risks
unique to conducting business in foreign countries, including:

56

Table of Contents

● difficulty in establishing or managing relationships with academic partners or contract research organizations,

or CROs, and physicians;

● different standards for the conduct of clinical trials;

● the absence in some countries of established groups with sufficient regulatory expertise for review of

protocols related to our novel approach;

● our inability to locate qualified local consultants, physicians and partners; and

● the potential burden of complying with a variety of foreign laws, medical standards and regulatory

requirements, including the regulation of pharmaceutical and biotechnology products and treatment.

If we have difficulty enrolling a sufficient number of patients to conduct our clinical trials as planned, we may

need to delay, limit or terminate ongoing or planned clinical trials, any of which would have an adverse effect on our
business, financial condition, results of operations and prospects.

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

The outcome of preclinical studies and early clinical trials may not be predictive of the success of later clinical 

trials, and interim results of clinical trials do not necessarily predict success in the results of completed clinical trials.  
Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage 
clinical trials after achieving positive results in earlier development, and we could face similar setbacks.  For example, the 
Phase I/IIa trial of BT1718 is being conducted by Cancer Research UK at up to seven sites in the United Kingdom, and our 
company-sponsored trials of BT5528 and BT8009 are also ongoing, and the interim results in all three of these trials, 
including specific patient responses we have observed and disclosed, may not be replicated in the completed data sets or in 
future trials at global clinical trial sites in a later stage clinical trial conducted by us or our collaborators.  Additionally, 
notwithstanding the commencement of vaccination efforts, the ongoing COVID-19 pandemic may negatively impact our 
ability to enroll participants in future or later stage trials. The design of a clinical trial can determine whether its results will 
support approval of a product and flaws in the design of a clinical trial may not become apparent until the clinical trial is 
well advanced.  We have limited experience in designing clinical trials and may be unable to design and execute a clinical 
trial to support marketing approval.

Preclinical and clinical data are often susceptible to varying interpretations and analyses.  Many companies that 

believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to 
obtain marketing approval for the product candidates.  Even if we, or any collaborators, believe that the results of clinical 
trials for our product candidates warrant marketing approval, the FDA or comparable foreign regulatory authorities may 
disagree and may not grant marketing approval of our product candidates.

In some instances, there can be significant variability in safety or efficacy results between different clinical trials 

of the same product candidate due to numerous factors, including changes in trial procedures set forth in protocols, 
differences in the size and type of the patient populations, our ability to enroll trial participants, including as a result of the 
ongoing COVID-19 pandemic and notwithstanding the commencement of vaccination efforts, changes in and adherence to 
the dosing regimen and other clinical trial protocols and the rate of dropout among clinical trial participants.  If we fail to 
receive positive results in clinical trials of our product candidates, the development timeline and regulatory approval and 
commercialization prospects for our most advanced product candidates, and, correspondingly, our business and financial 
prospects would be negatively impacted.

Failure to successfully validate, develop and obtain regulatory approval for companion diagnostics could harm our
drug development strategy.

We may employ companion diagnostics to help us more accurately identify patients within a particular subset,

both during our clinical trials and in connection with the commercialization of our product candidates that we are

57

Table of Contents

developing or may in the future develop.  Companion diagnostics are subject to regulation by the FDA and comparable 
foreign regulatory authorities as medical devices and require separate regulatory approval prior to commercialization.  We 
do not develop companion diagnostics internally and thus we will be dependent on the sustained cooperation and effort of 
our third-party collaborators in developing and obtaining approval for these companion diagnostics.  There can be no 
guarantees that we will successfully find a suitable collaborator to develop companion diagnostics.  We and our 
collaborators may encounter difficulties in developing and obtaining approval for the companion diagnostics, including 
issues relating to selectivity/specificity, analytical validation, reproducibility, or clinical validation.  Any delay or failure by 
our collaborators to develop or obtain regulatory approval of the companion diagnostics could delay or prevent approval of 
our product candidates.  In addition, our collaborators may encounter production difficulties that could constrain the supply 
of the companion diagnostics, and both they and we may have difficulties gaining acceptance of the use of the companion 
diagnostics in the clinical community.  If such companion diagnostics fail to gain market acceptance, our ability to derive 
revenues from sales of any products, if approved, will be adversely affected.  In addition, the diagnostic company with 
whom we contract may decide to discontinue selling or manufacturing the companion diagnostic that we anticipate using in 
connection with development and commercialization of our product candidates or our relationship with such diagnostic 
company may otherwise terminate.  We may not be able to enter into arrangements with another diagnostic company to 
obtain supplies of an alternative diagnostic test for use in connection with the development and commercialization of our 
product candidates or do so on commercially reasonable terms, which could adversely affect and/or delay the development 
or commercialization of our product candidates.

Our current or future product candidates may cause undesirable side effects or have other properties when used alone
or in combination with other approved products or investigational new drugs that could halt their clinical development,
prevent their marketing approval, limit their commercial potential or result in significant negative consequences.

Undesirable or clinically unmanageable side effects could occur and cause us or regulatory authorities to interrupt, 

delay or halt clinical trials and could result in a more restrictive label or the delay or denial of marketing approval by the 
FDA or comparable foreign regulatory authorities.  Results of our trials could reveal a high and unacceptable severity and 
prevalence of side effects or unexpected characteristics.  As of January 25, 2021, the most recent date for which 
information has been provided by the Cancer Research UK, the most common treatment-related adverse events (>15%, 
n=45) in subjects exposed to BT1718 in the ongoing Phase I/IIa clinical trial were anemia, diarrhea, nausea, vomiting, 
fatigue, alanine aminotransferase increase, aspartate aminotransferase increase, gamma-glutamyltransferase increase, 
decreased appetite, lethargy, peripheral neuropathy, and weight decrease. BT5528 has been dosed up to 8.5 mg/m2 weekly,
which we believe, based on pre-clinical studies, is toward the top of the therapeutic range, with transient neutropenia
observed at that dose. In addition, administered doses of BT8009, a second-generation BTC targeting Nectin-4, appear
well-tolerated with manageable adverse events in the dose-escalation phase in the ongoing Phase I/II trial.

If unacceptable side effect profiles arise, or side effects beyond those identified to date develop or worsen, as we 

continue development of our current or future product candidates, we, the FDA or comparable foreign regulatory 
authorities, the Institutional Review Boards, or IRBs, or independent ethics committees at the institutions in which our 
studies are conducted, or the Data Safety Monitoring Board, or DSMB, could suspend or terminate our clinical trials or the 
FDA or comparable foreign regulatory authorities could order us to cease clinical trials or deny approval of our product 
candidates for any or all targeted indications.  Treatment-related side effects could also affect patient recruitment or the 
ability of enrolled subjects to complete the trial, cause delays in ongoing clinical trials, or result in potential product 
liability claims.  In addition, these side effects may not be appropriately recognized or managed by the treating medical 
staff.  We may be required to train medical personnel using our product candidates to understand the side effect profiles for 
our clinical trials and upon any commercialization of any of our product candidates.  Inadequate training in recognizing or 
managing the potential side effects of our product candidates could result in patient injury or death.  Any of these 
occurrences may prevent us from achieving or maintaining market acceptance of the affected product candidate and may 
harm our business, financial condition and prospects significantly.

Three of our product candidates are currently undergoing safety testing in the form of Phase I/IIa or Phase I/II 

clinical trials.  None of our products have completed this testing to date.  While our current and future product candidates 
will undergo safety testing to the extent possible and, where applicable, under such conditions discussed with 

58

Table of Contents

regulatory authorities, not all adverse effects of drugs can be predicted or anticipated.  Unforeseen side effects could arise 
either during clinical development or, if such side effects are rarer, after our products have been approved by regulatory 
authorities and the approved product has been marketed, resulting in the exposure of additional patients.  So far, we have 
not demonstrated, and we cannot predict if ongoing or future clinical trials will demonstrate, that BT1718, BT5528, 
BT8009 or any other of our product candidates are safe in humans.

Moreover, clinical trials of our product candidates are conducted in carefully defined sets of patients who have 

agreed to enter into clinical trials.  Consequently, it is possible that our clinical trials may indicate an apparent positive 
effect of a product candidate that is greater than the actual positive effect, if any, or alternatively fail to identify undesirable 
side effects.  If, following approval of a product candidate, we, or others, discover that the product is less effective than 
previously believed or causes undesirable side effects that were not previously identified, any of the following 
consequences could occur:

● regulatory authorities may withdraw their approval of the product or seize the product;

● we, or any collaborators, may need to recall the product, or be required to change the way the product is

administered or conduct additional clinical trials;

● additional restrictions may be imposed on the marketing of, or the manufacturing processes for, the particular

product;

● we may be subject to fines, injunctions or the imposition of civil or criminal penalties;

● regulatory authorities may require the addition of labeling statements, such as a boxed warning or a

contraindication;

● we, or any collaborators, may be required to create a medication guide outlining the risks of the previously

unidentified side effects for distribution to patients;

● we, or any collaborators, could be sued and held liable for harm caused to patients;

● the product may become less competitive; and

● our reputation may suffer.

If any of our current or future product candidates fail to demonstrate safety and efficacy in clinical trials or do not 

gain marketing approval, we will not be able to generate revenue and our business will be harmed.  Any of these events 
could harm our business and operations, and could negatively impact the price of our ADSs.

We may be delayed or may not be successful in our efforts to identify or discover additional product candidates.

Although we intend to utilize our Bicycle screening platform to explore other therapeutic opportunities in addition 

to the product candidates that we are currently developing, we may fail to identify other product candidates for clinical 
development for a number of reasons.  For example, our research methodology may not be successful in identifying 
potential product candidates or those we identify may be shown to have harmful side effects or other characteristics that 
make them unmarketable or unlikely to receive regulatory approval.  A key part of our strategy is to utilize our screening 
technology to identify product candidates to pursue in clinical development.  Such product candidates will require 
additional, time-consuming development efforts prior to commercial sale, including preclinical studies, clinical trials and 
approval by the FDA and/or applicable foreign regulatory authorities.  All product candidates are prone to the risks of 
failure that are inherent in pharmaceutical product development.  If we fail to identify and develop additional potential 
product candidates, we may be unable to grow our business and our results of operations could be materially harmed.

59

Table of Contents

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 and managerial resources, we intend to focus on developing product candidates 

for specific indications that we identify as most likely to succeed, in terms of both their potential for marketing 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 product candidates.  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 the product candidate.

We face potential product liability, and, if successful claims are brought against us, we may incur substantial liability
and costs.  If the use of our product candidates harms patients, or is perceived to harm patients even when such harm is
unrelated to our product candidates, our regulatory approvals could be revoked or otherwise negatively impacted and
we could be subject to costly and damaging product liability claims.

The use of our product candidates in clinical trials and the sale of any products for which we obtain marketing 

approval expose us to the risk of product liability claims.  Product liability claims might be brought against us by patients, 
healthcare providers, pharmaceutical companies or others selling or otherwise coming into contact with our products.  
There is a risk that our product candidates may induce adverse events.  If we cannot successfully defend against product 
liability claims, we could incur substantial liability and costs.  In addition, regardless of merit or eventual outcome, product 
liability claims may result in:

● the impairment of our business reputation;

● the withdrawal of clinical trial participants;

● substantial monetary awards to patients or other claimants;

● costs due to related litigation;

● the distraction of management’s attention from our primary business;

● the inability to commercialize our product candidates; and

● decreased demand for our product candidates, if approved for commercial sale.

We may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us 
against losses due to liability.  We intend to expand our insurance coverage each time we commercialize an additional 
product; however, we may be unable to obtain product liability insurance on commercially reasonable terms or in adequate 
amounts.  On occasion, large judgments have been awarded in class action lawsuits based on drugs or medical treatments 
that had unanticipated adverse effects.  A successful product liability claim or series of claims brought against us could 
cause our ADS price to decline and, if judgments exceed our insurance coverage, could adversely affect our results of 
operations and business.

Patients with the diseases targeted by certain of our product candidates, such as our lead indications in oncology, 
are often already in severe and advanced stages of disease and have both known and unknown significant pre-existing and 
potentially life-threatening health risks.  During the course of treatment, patients may suffer adverse events, including 
death, for reasons that may be related to our product candidates.  Such events could subject us to costly litigation, require 
us to pay substantial amounts of money to injured patients, delay, negatively impact or end our 

60

Table of Contents

opportunity to receive or maintain regulatory approval to market our products, or require us to suspend or abandon our 
commercialization efforts.  Even in a circumstance in which we do not believe that an adverse event is related to our 
products, the investigation into the circumstance may be time-consuming or inconclusive.  These investigations may 
interrupt our sales efforts, delay our regulatory approval process, or impact and limit the type of regulatory approvals our 
product candidates receive or maintain.  As a result of these factors, a product liability claim, even if successfully 
defended, could have a material adverse effect on our business, financial condition or results of operations.

We may seek designations for our product candidates with the FDA and other comparable regulatory authorities that
are intended to confer benefits such as a faster development process or an accelerated regulatory pathway, but there can
be no assurance that we will successfully obtain such designations.  In addition, even if one or more of our product
candidates are granted such designations, we may not be able to realize the intended benefits of such designations.

The FDA and other comparable regulatory authorities offer certain designations for product candidates that are 
intended to encourage the research and development of pharmaceutical products addressing conditions with significant 
unmet medical need.  These designations may confer benefits such as additional interaction with regulatory authorities, a 
potentially accelerated regulatory pathway and priority review.  There can be no assurance that we will successfully obtain 
such designation for any of our other product candidates.  In addition, while such designations could expedite the 
development or approval process, they generally do not change the standards for approval.  Even if we obtain such 
designations for one or more of our product candidates, there can be no assurance that we will realize their intended 
benefits.

For example, we may seek a Breakthrough Therapy Designation for one or more of our product candidates.  A 

breakthrough therapy is defined as a therapy that is intended, alone or in combination with one or more other therapies, to 
treat a serious or life-threatening disease or condition, if preliminary clinical evidence indicates that the therapy may 
demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as 
substantial treatment effects observed early in clinical development.  For therapies that have been designated as 
breakthrough therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify 
the most efficient path for clinical development while minimizing the number of patients placed in ineffective control 
regimens.  Therapies designated as breakthrough therapies by the FDA are also eligible for accelerated approval.  
Designation as a breakthrough therapy is within the discretion of the FDA.  Accordingly, even if we believe one of our 
product candidates meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead 
determine not to make such designation.  In any event, the receipt of a Breakthrough Therapy Designation for a product 
candidate may not result in a faster development process, review or approval compared to therapies considered for 
approval under conventional FDA procedures and does not assure ultimate approval by the FDA.  In addition, even if one 
or more of our product candidates qualify as breakthrough therapies, the FDA may later decide that such product 
candidates no longer meet the conditions for qualification.

We may also seek Fast Track Designation for some of our product candidates.  If a therapy is intended for the 
treatment of a serious or life-threatening condition and the therapy demonstrates the potential to address unmet medical 
needs for this condition, the therapy sponsor may apply for Fast Track Designation.  The FDA has broad discretion whether 
or not to grant this designation, so even if we believe a particular product candidate is eligible for this designation, there 
can be no assurance that the FDA would decide to grant it.  Even if we do receive Fast Track Designation, we may not 
experience a faster development process, review or approval compared to conventional FDA procedures, and receiving a 
Fast Track Designation does not provide assurance of ultimate FDA approval.  The FDA may withdraw Fast Track 
Designation if it believes that the designation is no longer supported by data from our clinical development program.

We may seek priority review designation for one or more of our product candidates, but we might not receive such
designation, and even if we do, such designation may not lead to a faster regulatory review or approval process.

If the FDA determines that a product candidate offers a treatment for a serious condition and, if approved, the 

product would provide a significant improvement in safety or effectiveness, the FDA may designate the product candidate 
for priority review.  A priority review designation means that the goal for the FDA to review an application is 

61

Table of Contents

six months, rather than the standard review period of ten months.  We may request priority review for our product 
candidates.  The FDA has broad discretion with respect to whether or not to grant priority review status to a product 
candidate, so even if we believe a particular product candidate is eligible for such designation or status, in particular if such 
product candidate has received a Breakthrough Therapy Designation, the FDA may decide not to grant it.  Moreover, a 
priority review designation does not result in expedited development and does not necessarily result in expedited regulatory 
review or approval process or necessarily confer any advantage with respect to approval compared to conventional FDA 
procedures.  Receiving priority review from the FDA does not guarantee approval within the six-month review cycle or at 
all.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does
not mean that we will be successful in obtaining marketing approval of our current and future product candidates in
other jurisdictions.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction 

does not guarantee that we will be able to obtain or maintain marketing approval in any other jurisdiction, while a failure or 
delay in obtaining marketing approval in one jurisdiction may have a negative effect on the marketing approval process in 
others.  For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities 
in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those 
countries.  Approval procedures vary among jurisdictions and can involve requirements and administrative review periods 
different from, and greater than, those in the United States, including additional preclinical studies or clinical trials as 
clinical studies conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions.  In many 
jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved 
for sale in that jurisdiction.  In some cases, the price that we intend to charge for our products is also subject to approval.  
We do not have experience in obtaining reimbursement or pricing approvals in international markets.

Obtaining marketing approvals and compliance with regulatory requirements could result in significant delays, 
difficulties and costs for us and could delay or prevent the introduction of our products in certain countries outside of the 
United States.  If we fail to comply with the regulatory requirements in international markets and/or receive applicable 
marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product 
candidates will be harmed.

The  withdrawal  of  the  United  Kingdom  from  the  European  Union,  commonly  referred  to  as  “Brexit,”  may  adversely
impact our ability to obtain regulatory approvals of our product candidates in the European Union, result in restrictions
or imposition of taxes and duties for importing our product candidates into the European Union, and may require us to
incur additional expenses in order to develop, manufacture and commercialize our product candidates in the European
Union.

Following the result of a referendum in 2016, the United Kingdom left the European Union on January 31, 2020,
commonly referred to as Brexit.  Pursuant to the formal withdrawal arrangements agreed between the United Kingdom and
the  European  Union,  the  United  Kingdom  was  subject  to  a  transition  period  until  December  31,  2020,  or  the  Transition
Period,  during  which  European  Union  rules  continued  to  apply.   A  trade  and  cooperation  agreement,  or  the  Trade  and
Cooperation  Agreement,  which  outlines  the  future  trading  relationship  between  the  United  Kingdom  and  the  European
Union, was agreed upon in December 2020.

The potential impact on our results of operations and liquidity resulting from Brexit remains unclear. The actual

effects of Brexit will depend upon many factors and significant uncertainty remains with respect to the terms of the
ultimate resolution of the Brexit negotiations.

Since a significant proportion of the regulatory framework in the United Kingdom applicable to our business and

our product candidates is derived from European Union directives and regulations, Brexit has had, and may continue to
have, a material impact on the regulatory regime with respect to the development, manufacture, importation, approval and
commercialization of our product candidates in the United Kingdom or the European Union. For example, Great Britain is
no longer covered by the centralized procedures for obtaining European Union-wide marketing authorization

62

Table of Contents

from the EMA, and a separate marketing authorization will be required to market our product candidates in Great Britain.
It is currently unclear as to whether the Medicines & Healthcare products Regulatory Agency, or MHRA, is sufficiently 
prepared to handle the increased volume of marketing authorization applications that it is likely to receive. Any delay in 
obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, would prevent us from 
commercializing our product candidates in the United Kingdom and/or the European Union and restrict our ability to 
generate revenue and achieve and sustain profitability.  If any of these outcomes occur, we may be forced to restrict or 
delay efforts to seek regulatory approval in the United Kingdom and/or European Union for our product candidates, which 
could significantly and materially harm our business.

While the Trade and Cooperation Agreement provides for the tariff-free trade of medicinal products between the 

United Kingdom and the European Union, there may be additional non-tariff costs to such trade which did not exist prior to 
the end of the Transition Period.  Further, should the United Kingdom diverge from the European Union from a regulatory 
perspective in relation to medicinal products, tariffs could be put into place in the future.  We could, therefore, both now 
and in the future, face significant additional expenses (when compared to the position prior to the end of the Transition 
Period) to operate our business, which could significantly and materially harm or delay our ability to generate revenues or 
achieve profitability of our business. Any further changes in international trade, tariff and import/export regulations as a 
result of Brexit or otherwise may impose unexpected duty costs or other non-tariff barriers on us. These developments, or 
the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the 
impacted nations and the United Kingdom. It is also possible that Brexit may negatively affect our ability to attract and 
retain employees, particularly those from the European Union. 

Brexit may influence the attractiveness of the United Kingdom as a place to conduct clinical trials. The European 
Union’s regulatory environment for clinical trials is being harmonized as part of the Clinical Trial Regulations, which are 
due to enter into full effect at the end of 2021, but it is currently unclear as to what extent the United Kingdom will seek to 
align its regulations with the European Union. Failure of the United Kingdom to closely align its regulations with the 
European Union may have an effect on the cost of conducting clinical trials in the United Kingdom as opposed to other 
countries and/or make it harder to seek a marketing authorization for our product candidates on the basis of clinical trials 
conducted in the United Kingdom.  In the short term, there will be few changes to clinical trials that only have sites in the 
United Kingdom. The MHRA has confirmed that the sponsor of a clinical trial can be based in the EEA for an initial period 
following Brexit. Further investigational medicinal products can be supplied directly from the European Union/EEA to a 
trial site in Great Britain without further oversight until January 1, 2022, and to Northern Ireland beyond such date. The 
United Kingdom is now a “third country” for the purpose of clinical trials that have sites in the EEA. For such trials the 
sponsor/legal representative must be based in the EEA, and the trial must be registered on the E.U. Clinical Trials Register 
(including data on sites outside of the EEA).

Risks Related to Commercialization of Our Product Candidates and Other Regulatory Compliance Matters

Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is expensive,
time consuming and uncertain and may prevent us or any collaborators from obtaining approvals for the
commercialization of some or all of our product candidates.  As a result, we cannot predict when or if, and in which
territories, we, or any collaborators, will obtain marketing approval to commercialize a product candidate.

The process of obtaining marketing approvals, both in the United States and abroad, is lengthy, expensive and 

uncertain.  It may take many years, if approval is obtained at all, and can vary substantially based upon a variety of factors, 
including the type, complexity and novelty of the product candidates involved.  Securing marketing approval requires the 
submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each 
therapeutic indication to establish the product candidate’s safety and efficacy.  Securing marketing approval also requires 
the submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, 
the regulatory authorities.  The FDA or other regulatory authorities may determine that our product candidates are not safe 
and effective, only moderately effective or have undesirable or unintended side effects, toxicities or other characteristics 
that preclude our obtaining marketing approval or prevent or limit commercial use.  Any marketing approval we ultimately 
obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not 
commercially viable.

63

Table of Contents

In addition, changes in marketing approval policies during the development period, changes in or the enactment or 

promulgation of additional statutes, regulations or guidance or changes in regulatory review for each submitted product 
application, may cause delays in the approval or rejection of an application.  Regulatory authorities have substantial 
discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for 
approval and require additional preclinical, clinical or other studies.  Varying interpretations of the data obtained from 
preclinical and clinical testing could delay, limit or prevent marketing approval of a product candidate.  We cannot 
commercialize a product until the appropriate regulatory authorities have reviewed and approved the product candidate.  
Even if our product candidates demonstrate safety and efficacy in clinical trials, the regulatory agencies may not complete 
their review processes in a timely manner, or we may not be able to obtain regulatory approval.  Due to the ongoing 
COVID-19 pandemic, it is possible that we could experience delays in the timing of our interactions with regulatory 
authorities due to absenteeism by governmental employees, inability to conduct planned physical inspections related to 
regulatory approval, or the diversion of regulatory authority efforts and attention to approval of other therapeutics or other 
activities related to COVID-19, which could delay anticipated approval decisions and otherwise delay or limit our ability to 
make planned regulatory submissions or obtain new product approvals.  Additional delays may result if an FDA Advisory 
Committee or other regulatory authority recommends non-approval or restrictions on approval.  In addition, we may 
experience delays or rejections based upon additional government regulation from future legislation or administrative 
action, or changes in regulatory agency policy during the period of product development, clinical trials and the review 
process.  Any marketing approval we ultimately obtain, if any, may be limited or subject to restrictions or post-approval 
commitments that render the approved product not commercially viable.

Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from 

time to time and receive compensation in connection with such services.  Under certain circumstances, we may be required 
to report some of these relationships to the FDA or other regulatory authority.  The FDA or other regulatory authority may 
conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise 
affected interpretation of the trial.  The FDA or other regulatory authority may therefore question the integrity of the data 
generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized.  This could result 
in a delay in approval, or rejection, of our marketing applications by the FDA or other regulatory authority, as the case may 
be, and may ultimately lead to the denial of marketing approval of one or more of our product candidates.

In addition, regulatory agencies may not approve the labeling claims that are necessary or desirable for the 
successful commercialization of our product candidates.  For example, regulatory agencies may approve a product 
candidate for fewer or more limited indications than requested or may grant approval subject to the performance of post-
marketing studies.  Regulators may approve a product candidate for a smaller patient population, a different drug 
formulation or a different manufacturing process, than we are seeking.  If we are unable to obtain necessary regulatory 
approvals, or more limited regulatory approvals than we expect, our business, prospects, financial condition and results of 
operations may suffer.

Any delay in obtaining or failure to obtain required approvals could negatively impact our ability to generate

revenue from the particular product candidate, which likely would result in significant harm to our financial position and
adversely impact the price of our ADSs.

We currently have no marketing, sales or distribution infrastructure with respect to our product candidates.  If we are
unable to develop our sales, marketing and distribution capability on our own or through collaborations with marketing
partners, we will not be successful in commercializing our product candidates.

We currently have no marketing, sales or distribution capabilities and have limited sales or marketing experience 

within our organization.  If one or more of our product candidates is approved, we intend either to establish a sales and 
marketing organization with technical expertise and supporting distribution capabilities to commercialize that product 
candidate, or to outsource this function to a third party.  There are risks involved with either establishing our own sales and 
marketing capabilities and entering into arrangements with third parties to perform these services.

64

Table of Contents

Recruiting and training an internal commercial organization is expensive and time consuming and could delay any 
product launch.  Some or all of these costs may be incurred in advance of any approval of any of our product candidates.  If 
the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is 
delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization 
expenses.  This may be costly and our investment would be lost if we cannot retain or reposition our sales and marketing 
personnel.  In addition, we may not be able to hire a sales force in the United States or other target market that is sufficient 
in size or has adequate expertise in the medical markets that we intend to target.

Factors that may inhibit our efforts to commercialize our product candidates on our own include:

● the inability to recruit, train and retain adequate numbers of effective sales and marketing personnel;

● the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to

prescribe any future product that we may develop;

● the lack of complementary treatments to be offered by sales personnel, which may put us at a competitive

disadvantage relative to companies with more extensive product lines; and

● unforeseen costs and expenses associated with creating an independent sales and marketing organization.

If we enter into arrangements with third parties to perform sales, marketing and distribution services, our product 

revenue or the profitability to us from these revenue streams is likely to be lower than if we were to market and sell any 
product candidates that we develop ourselves.  In addition, we may not be successful in entering into arrangements with 
third parties to sell and market our product candidates or may be unable to do so on terms that are favorable to us.  We 
likely will have little control over such third parties and any of them may fail to devote the necessary resources and 
attention to sell and market our product candidates effectively.  If we do not establish sales and marketing capabilities 
successfully, either on our own or in collaboration with third parties, we may not be successful in commercializing our 
product candidates.

The market opportunities for any current or future product candidate we develop, if and when approved, may be limited
to those patients who are ineligible for established therapies or for whom prior therapies have failed, and may be small.

Cancer therapies are sometimes characterized as first-line, second-line, third-line or later-line therapies, and the 

FDA often approves new therapies initially only for third-line use.  When cancer is detected early enough, first-line 
therapy, usually chemotherapy, hormone therapy, surgery, radiation therapy, immunotherapy or a combination of these, is 
sometimes adequate to cure the cancer or prolong life without a cure.  Second- and third-line therapies are administered to 
patients when prior therapy is not effective.  We may initially seek approval of BT1718, BT5528, BT8009 and any other 
product candidates we develop as a therapy for patients who have received one or more prior treatments.  Subsequently, for 
those products that prove to be sufficiently beneficial, if any, we would expect to seek approval potentially as a first-line 
therapy, but there is no guarantee that product candidates we develop, even if approved, would be approved for first-line 
therapy, and, prior to any such approvals, we may have to conduct additional clinical trials.

The number of patients who have the cancers we are targeting may turn out to be lower than expected.  
Additionally, the potentially addressable patient population for our current programs or future product candidates may be 
limited, if and when approved.  Even if we obtain significant market share for any product candidate, if and when 
approved, if the potential target populations are small, we may never achieve profitability without obtaining marketing 
approval for additional indications, including use as first- or second-line therapy.

Even if we receive marketing approval of a product candidate, we will be subject to ongoing regulatory obligations and
continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we
fail to comply with regulatory requirements or experience unanticipated problems with our products, if approved.

65

Table of Contents

Any marketing approvals that we receive for any current or future product candidate may be subject to limitations 

on the approved indicated uses for which the product may be marketed or the conditions of approval, or contain 
requirements for potentially costly post-market testing and surveillance to monitor the safety and efficacy of the product 
candidate.  The FDA may also require a Risk Evaluation and Mitigation Strategy, or REMS, as a condition of approval of 
any product candidate, which could include requirements for a medication guide, physician communication plans or 
additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization 
tools.  If the FDA or a comparable foreign regulatory authority approves a product candidate, the manufacturing processes, 
labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import and export and record 
keeping for the product candidate will be subject to extensive and ongoing regulatory requirements.  These requirements 
include, among others, submissions of safety and other post-marketing information and reports, registration, as well as
continued compliance with current Good Manufacturing Practice, or cGMP, and Good Clinical Practice, or GCP, for any
clinical trials that we conduct post-approval, and prohibitions on the promotion of an approved product for uses not
included in the product’s approved labeling. 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 improperly promoted off-label may be
subject to significant liability. However, physicians may, in their independent medical judgment, prescribe legally available
products for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments but the FDA
does restrict manufacturer’s communications on the subject of off-label use of their products.

Later discovery of previously unknown problems with any approved candidate, including adverse events of
unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply
with regulatory requirements, may result in, among other things:

● restrictions on the labeling, distribution, marketing or manufacturing of the product, withdrawal of the

product from the market, or product recalls;

● untitled and warning letters, or holds on clinical trials;

● refusal by the FDA to approve pending applications or supplements to approved applications we filed or

suspension or revocation of license approvals;

● requirements to conduct post-marketing studies or clinical trials;

● restrictions on coverage by third-party payors;

● fines, restitution or disgorgement of profits or revenues;

● suspension or withdrawal of marketing approvals;

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

● injunctions or the imposition of civil or criminal penalties.

The FDA’s and other regulatory authorities’ policies may change and additional government regulations may be 

enacted that could prevent, limit or delay marketing approval of a product.  We cannot predict the likelihood, nature or 
extent of government regulation that may arise from future legislation or administrative action, either in the United States 
or abroad.  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 may have 
obtained and we may not achieve or sustain profitability.

We face significant competition and if our competitors develop and market products that are more effective, safer or less
expensive than the product candidates we develop, our commercial opportunities will be negatively impacted.

Table of Contents

The life sciences industry is highly competitive.  We are currently developing therapeutics that will compete, if 
approved, with other products and therapies that currently exist, are being developed or will in the future be developed, 
some of which we may not currently be aware.

We have competitors both in the United States and internationally, including major multinational pharmaceutical 

companies, established biotechnology companies, specialty pharmaceutical companies, universities and other research 
institutions.  Many of our competitors have significantly greater financial, manufacturing, marketing, product development, 
technical and human resources than we do.  Large pharmaceutical companies, in particular, have extensive experience in 
clinical testing, obtaining marketing approvals, recruiting patients and manufacturing pharmaceutical products.  These 
companies also have significantly greater research and marketing capabilities than we do and may also have 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.  Established pharmaceutical companies may also invest heavily to accelerate 
discovery and development of novel compounds or to in-license novel compounds that could make the product candidates 
that we develop obsolete.  Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even 
more resources being concentrated among a smaller number of our competitors.  As a result of all of these factors, our 
competitors may succeed in obtaining patent protection and/or marketing approval or discovering, developing and 
commercializing products in our field before we do.

There are a large number of companies developing or marketing treatments for cancer, including many major 
pharmaceutical and biotechnology companies.  These treatments consist both of small molecule drug products, such as 
traditional chemotherapy, as well as novel immunotherapies.  For example, a number of multinational companies as well as 
large biotechnology companies, including Astellas Pharma Inc., Seattle Genetics, Inc., AstraZeneca, GlaxoSmithKline plc, 
and Stemline Therapeutics Inc. are developing programs for the targets that we are exploring for our BTC programs.   
Furthermore, Agenus Inc., Bristol-Myers Squibb Company, Pfizer Inc., Roche Holding AG, or Roche, have or are 
developing programs for CD137, and Amgen Inc., Pieris Pharmaceuticals, Inc. and Roche are developing bi-specific 
antibodies.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize 

products that are safer, more effective, have fewer or less severe effects, are more convenient, have a broader label, are 
marketed more effectively, are reimbursed or are less expensive than any products that we may develop.  Our competitors 
also may obtain FDA, European or other marketing approval for their products more rapidly than we may obtain approval 
for ours, which could result in our competitors establishing a strong market position before we are able to enter the market.  
Even if the product candidates we develop achieve marketing approval, they may be priced at a significant premium over 
competitive products if any have been approved by then, resulting in reduced competitiveness.

Smaller and other early stage companies may also prove to be significant competitors.  These third parties 

compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites 
and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our 
programs.  In addition, the biopharmaceutical industry is characterized by rapid technological change.  If we fail to stay at 
the forefront of technological change, we may be unable to compete effectively.  Technological advances or products 
developed by our competitors may render our product candidates obsolete, less competitive or not economical.

The commercial success of any current or future product candidate will depend upon the degree of market acceptance
by physicians, patients, payors and others in the medical community.

We have never commercialized a product, and even if we obtain any regulatory approval for our product
candidates, the commercial success of our product candidates will depend in part on the medical community, patients, and
payors accepting products based on our Bicycle peptides in general, and our product candidates in particular, as effective, 
safe and cost-effective.  Any product that we bring to the market may not gain market acceptance by physicians, patients, 
payors and others in the medical community.  Physicians are often reluctant to switch their patients from existing therapies 
even when new and potentially more effective or convenient treatments enter the market.  Further, patients often acclimate 
to the therapy that they are currently taking and do not want to switch unless their 

67

Table of Contents

physicians recommend switching products or they are required to switch therapies due to lack of reimbursement for 
existing therapies.

The degree of market acceptance of these product candidates, if approved for commercial sale, will depend on a

number of factors, including:

● the potential efficacy and potential advantages over alternative treatments;

● the frequency and severity of any side effects, including any limitations or warnings contained in a product’s

approved labeling;

● the frequency and severity of any side effects resulting from follow-up requirements for the administration of

our product candidates;

● the relative convenience and ease of administration;

● the willingness of the target patient population to try new therapies and of physicians to prescribe these

therapies;

● the strength of marketing and distribution support and timing of market introduction of competitive products;

● publicity concerning our products or competing products and treatments; and

● sufficient third-party insurance coverage and adequate reimbursement.

Even if a product candidate displays a favorable efficacy and safety profile in preclinical studies and clinical trials, 
market acceptance of the product, if approved for commercial sale, will not be known until after it is launched.  Our efforts 
to educate the medical community and payors on the benefits of our product candidates may require significant resources 
and may never be successful.  Such efforts to educate the marketplace may require more resources than are required by the 
conventional technologies marketed by our competitors, particularly due to the novelty of our Bicycle approach.  If these 
products do not achieve an adequate level of acceptance, we may not generate significant product revenue and may not 
become profitable.

If the market opportunities for our product candidates are smaller than we believe they are, our product revenues may
be adversely affected and our business may suffer.

We currently focus our research and product development on treatments for oncology indications and our product 
candidates are designed to target specific tumor antigens.  Our understanding of both the number of people who have these 
diseases, as well as the subset of people with these diseases who have the potential to benefit from treatment with our 
product candidates, are based on estimates.  These estimates may prove to be incorrect and new studies may reduce the 
estimated incidence or prevalence of these diseases.  Patient identification efforts also influence the ability to address a 
patient population.  If efforts in patient identification are unsuccessful or less impactful than anticipated, we may not 
address the entirety of the opportunity we are seeking.

In addition, the tumor antigens that our product candidates target may not be expressed as broadly as we 
anticipate.  Further, if companion diagnostics are not developed alongside our product candidates, testing patients for the 
tumor antigens may not be possible, which would hamper our ability to identify patients who could benefit from treatment 
with our product candidates.

As a result, the number of patients we are able to identify in the United States, the European Union and elsewhere

may turn out to be lower than expected, may not be otherwise amenable to treatment with our products or patients may
become increasingly difficult to access, all of which would adversely affect our business, financial condition, results of
operations and prospects.

The insurance coverage and reimbursement status of newly-approved products is uncertain.  Failure to obtain or
maintain adequate coverage and reimbursement for any of our product candidates, if approved, could limit our ability
to market those products and decrease our ability to generate revenue.

We expect the cost of our product candidates to be substantial, when and if they achieve market approval.  The 
availability and extent of reimbursement by governmental and private payors is essential for most patients to be able to 
afford expensive treatments.  Sales of our product candidates will depend substantially, both domestically and abroad, on 
the extent to which the costs of our product candidates will be paid by private payors, such as private health coverage 
insurers, health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or 
reimbursed by government health care programs, such as Medicare and Medicaid.  We may not be able to provide data 
sufficient to gain acceptance with respect to coverage and reimbursement.  If reimbursement is not available, or is available 
only at limited levels, we may not be able to successfully commercialize our product candidates, even if approved.  Even if 
coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain 
pricing sufficient to realize a sufficient return on our investment.

There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products.  

In the United States, the principal decisions about coverage and reimbursement for new medicines are typically made by 
CMS, as the CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare.  
Private payors tend to follow CMS to a substantial degree.  It is difficult to predict what CMS will decide with respect to 
coverage and reimbursement for novel products such as ours, as there is no body of established practices and precedents for 
these new products.  Coverage and reimbursement by a third-party payor may depend upon a number of factors, including 
the third-party payor’s determination that use of a product is:  (1) a covered benefit under its health plan; (2) safe, effective 
and medically necessary; (3) appropriate for the specific patient; (4) cost-effective; and (5) neither experimental nor 
investigational.  In the United States, no uniform policy of coverage and reimbursement for products exists among third-
party payors.  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.  Even if we obtain 
coverage for a given product, the resulting reimbursement payment rates might not be adequate for us to achieve or sustain 
profitability or may require co-payments that patients find unacceptably high.  Third-party payors may limit coverage to 
specific drug products on an approved list, also known as a formulary, which might not include all of the approved drugs 
for a particular indication.

Additionally, third-party payors may not cover, or provide adequate reimbursement for, long-term follow-up 

evaluations required following the use of product candidates.  Patients are unlikely to use our product candidates unless 
coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our product candidates.  
Because our product candidates may have a higher cost of goods than conventional therapies, and may require long-term 
follow-up evaluations, the risk that coverage and reimbursement rates may be inadequate for us to achieve profitability 
may be greater.  There is significant uncertainty related to insurance coverage and reimbursement of newly approved 
products.  It is difficult to predict at this time what third-party payors will decide with respect to the coverage and 
reimbursement for our product candidates.

We or our collaborators will be required to obtain coverage and reimbursement for companion diagnostic tests

separate and apart from the coverage and reimbursement we seek for our product candidates, once approved. There is
significant uncertainty regarding our and our collaborators ability to obtain coverage and adequate reimbursement for any
companion diagnostic test for the same reasons applicable to our product candidates.

Outside the United States, certain countries, including a number of member states of the European Union, set 
prices and reimbursement for pharmaceutical products, or medicinal products, as they are commonly referred to in the 
European Union.  These countries have broad discretion in setting prices and we cannot be sure that such prices and 
reimbursement will be acceptable to us or our collaborators.  If the regulatory authorities in these jurisdictions set prices or 
reimbursement levels that are not commercially attractive for us or our collaborators, our revenues from sales by us or our 
collaborators, and the potential profitability of our drug products, in those countries would be negatively affected.  An 
increasing number of countries are taking initiatives to attempt to reduce large budget deficits by focusing cost-

69

Table of Contents

cutting efforts on pharmaceuticals for their state-run health care systems.  These international price control efforts have 
impacted all regions of the world, but have been most drastic in the European Union.  Additionally, some countries require 
approval of the sale price of a product before it can be lawfully marketed.  In many countries, the pricing review period 
begins after marketing or product licensing approval is granted.  To obtain reimbursement or pricing approval in some 
countries, we, or any collaborators, may be required to conduct a clinical trial that compares the cost-effectiveness of our 
product to other available therapies.  As a result, we might obtain marketing approval for a product in a particular country, 
but then may experience delays in the reimbursement approval of our product or be subject to price regulations that would 
delay our commercial launch of the product, possibly for lengthy time periods, which could negatively impact the revenues 
we are able to generate from the sale of the product in that particular country.

Moreover, efforts by governments and payors, in the United States and abroad, to cap or reduce healthcare costs 

may cause such organizations to limit both coverage and level of reimbursement for new products approved and, as a 
result, they may not cover or provide adequate reimbursement for our product candidates.  There has been increasing 
legislative and enforcement interest in the United States with respect to specialty drug practices.  Specifically, there have 
been several recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other 
things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the 
relationship between pricing and manufacturer patient programs, and reform government program reimbursement 
methodologies for drugs.  We expect to experience pricing pressures in connection with the sale of any of our product 
candidates, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and 
additional legislative changes.  The downward pressure on healthcare costs in general, particularly prescription drugs and 
other treatments, has become very intense.  As a result, increasingly high barriers are being erected to the entry of new 
products.

If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory

levels, our business could be harmed.

If the FDA or comparable foreign regulatory authorities approve generic versions of any of our product candidates that
receive marketing approval, or such authorities do not grant such products appropriate periods of data exclusivity
before approving generic versions of such products, the sales of such products could be adversely affected.

Once a NDA is approved, the product covered thereby becomes a “reference-listed drug” in the FDA’s 
publication, “Approved Drug Products with Therapeutic Equivalence Evaluations,” or the Orange Book.  Manufacturers 
may seek approval of generic versions of reference-listed drugs through submission of abbreviated new drug applications, 
or ANDAs, in the United States.  In support of an ANDA, a generic manufacturer generally must show that its product has 
the same active ingredient(s), dosage form, strength, route of administration and conditions of use or labeling as the 
reference-listed drug and that the generic version is bioequivalent to the reference-listed drug, meaning, in part, that it is 
absorbed in the body at the same rate and to the same extent.  Generic products may be significantly less costly to bring to 
market than the reference-listed drug and companies that produce generic products are generally able to offer them at lower 
prices.  Thus, following the introduction of a generic drug, a significant percentage of the sales of any branded product or 
reference-listed drug may be typically lost to the generic product, and the price of the branded product may be lowered.

The FDA may not accept for review or approve an ANDA for a generic product until any applicable period of 
non-patent exclusivity for the reference-listed drug has expired.  The Federal Food, Drug, and Cosmetic Act, or FDCA, 
provides a period of five years of non-patent exclusivity for a new drug containing a new chemical entity, or NCE.  
Specifically, in cases where such exclusivity has been granted, an ANDA may not be filed with the FDA until the 
expiration of five years unless the submission is accompanied by a Paragraph IV certification that a patent covering the 
reference-listed drug is either invalid or will not be infringed by the generic product, in which case the applicant may 
submit its application four years following approval of the reference-listed drug.  It is unclear whether the FDA will treat 
the active ingredients in our product candidates as NCEs and, therefore, afford them five years of NCE data exclusivity if 
they are approved.  If any product we develop does not receive five years of NCE exclusivity, the FDA may approve 
generic versions of such product three years after its date of approval, subject to the requirement that the ANDA applicant 
certifies to any patents listed for our products in the Orange Book.  Three year exclusivity is given to a non-NCE drug if 
the NDA includes reports of one or more new clinical investigations, other than bioavailability or 

70

Table of Contents

bioequivalence studies, that were conducted by or for the applicant and are essential to the approval of the NDA.  
Manufacturers may seek to launch these generic products following the expiration of the applicable marketing exclusivity 
period, even if we still have patent protection for our product.

Competition that our products may face from generic versions of our products could negatively impact our future

revenue, profitability and cash flows and substantially limit our ability to obtain a return on our investments in those
product candidates.

We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws health
information privacy and security laws, and other health care laws and regulations.  If we are unable to comply, or have
not fully complied, with such laws, we could face substantial penalties.

If we obtain FDA approval for any of our product candidates and begin commercializing those products in the 
United States, our operations will be directly, or indirectly through our prescribers, customers and purchasers, subject to 
various federal and state fraud and abuse laws and regulations, including, without limitation, the federal Health Care 
Program Anti-Kickback Statute, or Anti-Kickback Statute, the federal civil and criminal False Claims Act and Physician 
Payments Sunshine Act and regulations.  These laws will impact, among other things, our clinical research, proposed sales, 
marketing and educational programs and other interactions with healthcare professionals.  In addition, we may be subject 
to patient privacy laws by both the federal government and the states in which we conduct our business.  The laws that will 
affect our operations include, but are not limited to:

● the Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly and 

willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe or rebate), 
directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, either the referral of an 
individual, or the purchase, lease, order, arrangement, or recommendation of any good, facility, item or 
service for which payment may be made, in whole or in part, under a federal healthcare program, such as the 
Medicare and Medicaid programs.  “Remuneration” has been interpreted broadly to include anything of 
value.  A person or entity does not need to have actual knowledge of the Anti-Kickback Statute or specific 
intent to violate it to have committed a violation.  In addition, the government may assert that a claim 
including items or services resulting from a violation of the Anti-Kickback Statute constitutes a false or 
fraudulent claim for purposes of the federal False Claims Act, or FCA, or federal civil money penalties.  The 
Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers 
on the one hand and prescribers, purchasers, and formulary managers on the other.  There are a number of 
statutory exceptions and regulatory safe harbors protecting some common activities from prosecution;

● the federal civil and criminal false claims laws, including the FCA, and civil monetary penalty laws, which 
impose criminal and civil penalties against individuals or entities for, among other things:  knowingly 
presenting, or causing to be presented, to the federal government, claims for payment that are false or 
fraudulent; knowingly making, using or causing to be made or used, a false statement of record material to a 
false or fraudulent claim or obligation to pay or transmit money or property to the federal government.  
Manufacturers can be held liable under the FCA even when they do not submit claims directly to government 
payors if they are deemed to “cause” the submission of false or fraudulent claims.  The FCA also permits a 
private individual acting as a “whistleblower” to bring actions on behalf of the federal government alleging 
violations of the FCA and to share in any monetary recovery;

● the beneficiary inducement provisions of the CMP Law, which prohibits, among other things, the offering or
giving of remuneration, which includes, without limitation, any transfer of items or services for free or for
less than fair market value (with limited exceptions), to a Medicare or Medicaid beneficiary that the person
knows or should know is likely to influence the beneficiary’s selection of a particular supplier of items or
services reimbursable by a federal or state governmental program;

● the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created new
federal criminal statutes that prohibit a person from knowingly and willfully executing, or attempting to

71

Table of Contents

execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent
pretenses, representations or promises, any of the money or property owned by, or under the custody or
control of, any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and
willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially
false, fictitious, or fraudulent statements or representations in connection with the delivery of, or payment for,
healthcare benefits, items or services relating to healthcare matters; similar to the Anti-Kickback Statute, a
person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order
to have committed a violation;

● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009,
and their respective implementing regulations, which impose requirements on certain healthcare providers,
health plans, and healthcare clearinghouses, known as covered entities, as well as their respective business
associates, individuals and entities that perform services on their behalf that involve the use or disclosure of
individually identifiable health information and their subcontractors that use disclose or otherwise process
individually identifiable health information, relating to the privacy, security and transmission of individually
identifiable health information;

● the U.S. federal transparency requirements under the Patient Protection and Affordable Care Act, as amended 

by the Health Care and Education Reconciliation Act, or collectively, ACA, including the provision 
commonly referred to as the Physician Payments Sunshine Act, which requires applicable manufacturers of 
drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or 
the Children’s Health Insurance Program (with certain exceptions) to report annually to CMS information 
related to payments or other transfers of value made to physicians (defined to include doctors, dentists, 
optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment 
interests held by the physicians described above and their immediate family members.  Beginning in 2022, 
applicable manufacturers also will be required to report information regarding payments and transfers of 
value provided, during the previous year to physician assistants, nurse practitioners, clinical nurse specialists,
certified nurse anesthetists, anesthesiologist assistants and certified nurse-midwives;

● federal government price reporting laws, which require us to calculate and report complex pricing metrics in

an accurate and timely manner to government programs; and

● federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and

activities that potentially harm consumers.

Additionally, we are subject to state and foreign equivalents of each of the healthcare laws and regulations 
described above, among others, some of which may be broader in scope and may apply regardless of the payer.  Many U.S. 
states have adopted laws similar to the Anti-Kickback Statute and FCA, and may apply to our business practices, including, 
but not limited to, research, distribution, sales or marketing arrangements and claims involving healthcare items or services 
reimbursed by non-governmental payors, including private insurers.  In addition, some states have passed laws that require 
pharmaceutical companies to comply with the April 2003 Office of Inspector General Compliance Program Guidance for 
Pharmaceutical Manufacturers and/or the Pharmaceutical Research and Manufacturers of America’s Code on Interactions 
with Healthcare Professionals.  Several states also impose other marketing restrictions or require pharmaceutical 
companies to make marketing or price disclosures to the state.  Certain states and local jurisdictions also require the 
registration of pharmaceutical sales representatives.  There are ambiguities as to what is required to comply with these state 
requirements, and if we fail to comply with an applicable state law requirement we could be subject to significant penalties.  
Finally, there are state and foreign laws governing the privacy and security of health information, many of which differ 
from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors 
available, it is possible that some of our business activities could be subject to challenge under one or more of such laws.  
Law enforcement authorities are increasingly focused on enforcing fraud and abuse laws, and it is possible that some of 

72

Table of Contents

our practices may be challenged under these laws.  Efforts to ensure that our current and future business arrangements with 
third parties, and our business generally, will comply with applicable healthcare laws and regulations will involve 
substantial costs.  If our operations, including our arrangements with physicians and other healthcare providers, some of 
whom receive share options as compensation for services provided, are found to be in violation of any of such laws or any 
other governmental regulations that apply to us, we may be subject to penalties, including, without limitation, significant
administrative, civil and criminal penalties, damages, fines, disgorgement, contractual damages, reputational harm,
diminished profits and future earnings, the curtailment or restructuring of our operations, imprisonment, exclusion from 
participation in federal and state healthcare programs (such as Medicare and Medicaid), additional reporting requirements 
and/or oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-
compliance with these laws, and imprisonment, any of which could adversely affect our ability to operate our business and 
our financial results. Any action for violation of these laws, even if successfully defended, could cause a pharmaceutical 
manufacturer to incur significant legal expenses and divert management’s attention from the operation of the business.  
Prohibitions or restrictions on sales or withdrawal of future marketed products could materially affect business in an 
adverse way.

Healthcare legislative reform measures may have a negative impact on our business and results of operations.

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 candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell any product
candidates for which we obtain marketing approval. Changes in regulations, statutes or the interpretation of existing
regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing
arrangements, (ii) additions or modifications to product labeling, (iii) the recall or discontinuation of our products,
(iv) restriction on coverage, reimbursement, and pricing for our products, (v) transparency reporting obligations regarding
transfers of value to health care professionals or (vi) additional record-keeping requirements. If any such changes were to
be imposed, they could adversely affect our business, financial condition and results of operations.

Among policy makers 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. In the
United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by
major legislative initiatives. In March 2010, the Affordable Care Act, or ACA, was passed, which substantially changed the
way healthcare is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical
industry. The ACA, among other things, subjected biological products to potential competition by lower-cost biosimilars,
created 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 and taxes on manufacturers of certain branded
prescription drugs, and created a new Medicare Part D coverage gap discount program, in which manufacturers must agree
to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their
coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

Since January 2017, former President Trump signed Executive Orders and other directives designed to delay the
implementation of certain provisions of the ACA or otherwise circumvent some of the requirements for health insurance
mandated by the ACA. One Executive Order directed federal agencies with authorities and responsibilities under the ACA
to waive, defer, grant exemptions from, or delay the implementation of any provision of the ACA that would impose a
fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals
or medical devices. Another Executive Order terminated the cost- sharing subsidies that reimburse insurers under the ACA.
Several state Attorneys General filed suit to stop the administration from terminating the subsidies, but their request for a
restraining order was denied by a federal judge in California on October 25, 2017. Further, on June 14, 2018, U.S. Court of
Appeals for the Federal Circuit ruled that the federal government was not required to pay more than $12 billion in ACA
risk corridor payments to third-party payors who argued were owed to them. On April 27, 2020, the U.S. Supreme Court
reversed the Federal Circuit decision that previously upheld Congress’

73

Table of Contents

denial of $12 billion in “risk corridor.”  The full effects of this gap in reimbursement on third-party payors, the viability of 
the ACA marketplace, providers, and potentially our business, are not yet known.

Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. 

While Congress has not passed comprehensive repeal legislation, several bills affecting implementation of certain taxes 
under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or the Tax Act, includes a provision that 
repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the Affordable Care Act on 
certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as 
the “individual mandate.” In addition, the 2020 federal spending package permanently eliminated, effective January 1, 
2020, the ACA-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, 
effective January 1, 2021, also eliminated the health insurer tax. The Bipartisan Budget Act of 2018, or the BBA, among 
other things, amended the Affordable Care Act, effective January 1, 2019, to close the coverage gap in most Medicare drug 
plans, commonly referred to as the “donut hole.” On December 14, 2018, a U.S. District Court Judge in the Northern 
District of Texas, or the Texas District Court Judge, ruled that the individual mandate is a critical and inseverable feature of 
the Affordable Care Act, and therefore, because it was repealed as part of the Tax Act, the remaining provisions of the 
Affordable Care Act are invalid as well. Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit 
upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District 
Court to determine whether the remaining provisions of the ACA are invalid as well.  The U.S. Supreme Court is currently 
reviewing this case, but it is unknown when a decision will be reached. Although the U.S. Supreme Court has yet ruled on 
the constitutionality of the ACA, on January 28, 2021, President Biden issued an executive order to initiate a special 
enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage 
through the ACA marketplace. The executive order also instructs certain governmental agencies to review and reconsider 
their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid 
demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers 
to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how the Supreme Court ruling, 
other such litigation, and the healthcare reform measures of the Biden administration will impact the ACA and our 
business.

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 2% per fiscal year pursuant to the Budget Control Act 
of 2011, which began in 2013, and due to subsequent legislative amendments to the statute, including the BBA, will remain 
in effect through 2030 unless additional Congressional action is taken. However, pursuant to certain COVID-19 relief 
legislation these Medicare sequester reductions have been suspended from May 1, 2020 through March 31, 2021.  The 
American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, 
including hospitals and cancer treatment centers, and increased the statute of limitations period for the government to 
recover overpayments to providers from three to five years.

There has been increasing legislative and enforcement interest in the United States with respect to specialty drug 
pricing practices. Specifically, there have been several recent U.S. Congressional inquiries and proposed federal and state 
legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs 
under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government 
program reimbursement methodologies for drugs. At the federal level, the former Trump administration used several means 
to propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy 
initiatives. For example, on July 24, 2020 and September 13, 2020, former President Trump signed several Executive 
Orders aimed at lowering drug pricing that seek to implement several of the administration's proposals. In response, the 
FDA released a final rule on September 24, 2020, which went into effect on November 30, 2020, providing guidance for 
states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020 CMS issued an Interim 
Final Rule implementing the Most Favored Nation, or MFN, Model under which Medicare Part B reimbursement rates will 
be calculated for certain drugs and biologicals based on the lowest price drug manufacturers receive in Organization for 
Economic Cooperation and Development countries with a similar gross domestic product per capita.  The MFN Model 
regulations mandate participation by identified Part B providers and will apply in all U.S. states and territories for a seven-
year period and was scheduled to begin on January 1, 2021 and end on December 31, 2027.   On December 28, 2020, the 
United States District Court in Northern California issued a nationwide preliminary injunction against implementation of 
the interim final rule. Additionally, on November 

74

Table of Contents

20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical 
manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price 
reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 
2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions 
reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit 
managers and manufacturers the implementation of which have also been delayed pending review by the Biden 
administration until March 22, 2021. However, it is unclear whether the Biden administration will work to reverse these 
measures or pursue similar policy initiatives.  At the state level, legislatures have increasingly passed legislation and 
implemented regulations designed to control pharmaceutical and biological 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.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation,

administrative or executive action. We expect that these and other healthcare reform measures that may be adopted in the
future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for
any approved drug, which could have an adverse effect on customers for our product candidates. It is possible that
additional governmental action is taken to address the ongoing COVID-19 pandemic. Any reduction in reimbursement
from Medicare or other government programs may result in a similar reduction in payments from private payors.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and

state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The
implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate
revenue, attain profitability, or commercialize our products. Such reforms could have an adverse effect on anticipated
revenue 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.

We are subject to the U.K. Bribery Act 2010, or the Bribery Act, the U.S. Foreign Corrupt Practices Act of 1977, as
amended, or the FCPA, and other anti-corruption laws, as well as export control laws, import and customs laws, trade
and economic sanctions laws and other laws governing our operations.

Our operations are subject to anti-corruption laws, including the Bribery Act, the FCPA, the U.S. domestic bribery 

statute contained in 18 U.S.C. §201, the U.S. Travel Act, and other anti-corruption laws that apply in countries where we 
do business.  The Bribery Act, the FCPA and these other laws generally prohibit us, our employees and our intermediaries 
from authorizing, promising, offering, or providing, directly or indirectly, improper or prohibited payments, or anything 
else of value, to government officials or other persons to obtain or retain business or gain some other business advantage.  
Under the Bribery Act, we may also be liable for failing to prevent a person associated with us from committing a bribery 
offense.  We and our commercial partners operate in a number of jurisdictions that pose a high risk of potential Bribery Act 
or FCPA violations, and we participate in collaborations and relationships with third parties whose corrupt or illegal 
activities could potentially subject us to liability under the Bribery Act, FCPA or local anti-corruption laws, even if we do 
not explicitly authorize or have actual knowledge of such activities.  In addition, we cannot predict the nature, scope or 
effect of future regulatory requirements to which our international operations might be subject or the manner in which 
existing laws might be administered or interpreted.

We are also subject to other laws and regulations governing our international operations, including regulations
administered by the governments of the United Kingdom and the United States, and authorities in the European Union,
including applicable export control regulations, economic sanctions and embargoes on certain countries and persons, anti-
money laundering laws, import and customs requirements and currency exchange regulations, collectively referred to as
the Trade Control laws.

There is no assurance that we will be completely effective in ensuring our compliance with all applicable anti-

corruption laws, including the Bribery Act, the FCPA or other legal requirements, including Trade Control laws.  If we are 
not in compliance with the Bribery Act, the FCPA and other anti-corruption laws or Trade Control laws, we may be subject 
to criminal and civil penalties, disgorgement and other sanctions and remedial measures, and legal expenses, 

75

which could have an adverse impact on our business, financial condition, results of operations and liquidity.  Likewise, any 
investigation of any potential violations of the Bribery Act, the FCPA, other anti-corruption laws or Trade Control laws by 
the United Kingdom, United States or other authorities could also have an adverse impact on our reputation, our business, 
results of operations and financial condition.

Our activities in the United States subject us to various laws relating to foreign investment and the export of certain
technologies, and our failure to comply with these laws or adequately monitor the compliance of our suppliers and
others we do business with could subject us to substantial fines, penalties and even injunctions, the imposition of which
on us could have a material adverse effect on the success of our business.

Because we have a U.S. subsidiary and substantial operations in the United States, we are subject to U.S. laws that 
regulate foreign investments in U.S. businesses and access by foreign persons to technology developed and produced in the 
United States.  These laws include section 721 of the Defense Production Act of 1950, as amended by the Foreign 
Investment Risk Review Modernization Act of 2018, and the regulations at 31 C.F.R.  Parts 800 and 801, as amended, 
administered by the Committee on Foreign Investment in the United States; and the Export Control Reform Act of 2018, 
which is being implemented in part through Commerce Department rulemakings to impose new export control restrictions 
on “emerging and foundational technologies” yet to be fully identified.  Application of these laws, including as they are 
implemented through regulations being developed, may negatively impact our business in various ways, including by 
restricting our access to capital and markets; limiting the collaborations we may pursue; regulating the export our products, 
services, and technology from the United States and abroad; increasing our costs and the time necessary to obtain required 
authorizations and to ensure compliance; and threatening monetary fines and other penalties if we do not.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or
penalties or incur costs that could have a material adverse effect on the success of our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing 

laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes.  Our 
operations involve the use of hazardous and flammable materials, including chemicals and biological materials.  Our 
operations also produce hazardous waste products.  We generally contract with third parties for the disposal of these 
materials and wastes.  We cannot eliminate the risk of contamination or injury from these materials.  In the event of 
contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, 
and any liability could exceed our resources.  We also could incur significant costs associated with civil or criminal fines 
and penalties.  Furthermore, environmental laws and regulations are complex, change frequently and have tended to 
become more stringent.  We cannot predict the impact of such changes and cannot be certain of our future compliance.  In 
addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws 
and regulations.  These current or future laws and regulations may impair our research, development or production efforts.  
Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

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 hazardous materials or other work-related injuries, this insurance may 
not provide adequate coverage against potential liabilities.  In addition, we may incur substantial costs in order to comply 
with current or future environmental, health and safety laws and regulations.  These current or future laws and regulations 
may impair our research, development or production efforts.  Failure to comply with these laws and regulations also may 
result in substantial fines, penalties or other sanctions or liabilities, which could materially adversely affect our business, 
financial condition, results of operations and prospects.

Risks Related to Our Business and Our International Operations

COVID-19 could impact our business.

Our business could be adversely affected by the effects of the ongoing COVID-19 pandemic in regions where we

or third parties on which we rely have significant manufacturing facilities, concentrations of clinical trial sites or

76

Table of Contents

other business operations. The COVID-19 pandemic could materially affect our operations as well as causing significant
disruption in the operations and business of third-party manufacturers, CROs, other services providers, and collaborators
with whom we conduct business.

In response to the COVID-19 pandemic, many state, local and foreign governments, including the UK and U.S. 

put in place quarantines, executive orders, shelter-in-place or stay-at-home orders and similar government orders and 
restrictions in order to control the spread of the disease. While some restrictions have recently been relaxed, others have  
been re-imposed following prior relaxation as a result of continually evolving incidence and rates of infection. Such orders 
or restrictions, or the perception that such orders or restrictions could occur or continue for a protracted period of time, 
have resulted in business closures, work stoppages, slowdowns and delays, work-from-home policies, travel restrictions 
and cancellation of events, among other effects that could negatively impact productivity and disrupt our business and 
those of third-party manufacturers, CROs, other services providers, and collaborators with whom we conduct business. 
While the rollout of vaccines has begun, the timing of vaccinations, lifting of movement restrictions, and reinstitution of in-
person events is unknown.

As a result of the COVID-19 pandemic, certain of our employees continue to work remotely. We have prepared 

plans to reopen our offices to allow non-laboratory based employees to return to the office, which will be based on a 
phased approach. However, in light of continually changing circumstances regarding infection rates and local government 
recommendations, we may be required to suspend or reverse any planned return to the office in the future.  Additionally, 
we may experience disruptions if our employees become ill, despite the availability of vaccines, and are unable to perform 
their duties.  The effects of any of our work-from-home policies may negatively impact productivity, disrupt our business 
and delay our clinical programs and timelines, the magnitude of which will depend, in part, on the length and severity of 
the restrictions and other limitations on our ability to conduct our business in the ordinary course. 

In addition, our ability to conduct clinical trials has been and may continue to be affected by the COVID-19
pandemic. For example, all clinical sites for the Phase I/IIa trial of BT1718 being conducted by Cancer Research UK in the
United Kingdom temporarily paused enrollment of new patients due to the COVID-19 pandemic during the first half of
2020. While the pause in enrollment has been lifted during the second quarter of 2020 and patient enrollment in the Phase
IIa portion of the clinical trial is again underway, further clinical site initiation and patient enrollment may be suspended
again or delayed due to prioritization of hospital resources toward the COVID-19 pandemic, including vaccination efforts,
or new or renewed shelter-in-place or stay-at-home orders. Some patients may not be able to comply with clinical trial
protocols if quarantines impede patient movement or interrupt healthcare services. Similarly, our ability to recruit and
retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to
COVID-19, may adversely impact our future clinical trial operations.

The pandemic and related government and private sector responsive actions have affected the broader economies 
and financial markets, triggering an economic downturn, which has at points adversely affected, and could again adversely 
affect, our ability to access capital, which could negatively affect our liquidity.  In addition, a recession or resulting adverse 
impacts on the capital markets resulting from the ongoing spread of COVID-19 could materially affect our business. 

It is impossible to predict all effects and the ultimate impact of the COVID-19 pandemic, as the situation 
continues to evolve.  The full extent of COVID-19’s impact on our clinical development and other operations and financial 
performance depends on future developments that are uncertain and unpredictable, including the timing of vaccine rollouts 
and herd immunity, virus mutations and variants, and any new information that may emerge concerning the virus, vaccines, 
and containment, all of which may vary across regions. Any of these factors could have a material adverse impact on our 
business, financial condition, operating results, and ability to execute and capitalize on our strategies.

As a company based outside of the United States, we are subject to economic, political, regulatory and other risks
associated with international operations.

77

Table of Contents

As a company based in the United Kingdom, our business is subject to risks associated with conducting business 

outside of the United States.  Many of our suppliers and clinical trial relationships are located outside the United States.  
Accordingly, our future results could be harmed by a variety of factors, including:

● economic weakness, including inflation, or political instability in particular non-U.S. economies and markets;

● differing and changing regulatory requirements for product approvals;

● differing jurisdictions could present different issues for securing, maintaining or obtaining freedom to operate

in such jurisdictions;

● potentially reduced protection for intellectual property rights;

● difficulties in compliance with different, complex and changing laws, regulations and court systems of
multiple jurisdictions and compliance with a wide variety of foreign laws, treaties and regulations;

● changes in non-U.S. regulations and customs, tariffs and trade barriers;

● changes in non-U.S. currency exchange rates of the pound sterling, U.S. dollar, euro and currency controls;

● changes in a specific country’s or region’s political or economic environment, including the implications of

the recent decision of the United Kingdom to withdraw from the European Union;

● trade protection measures, import or export licensing requirements or other restrictive actions by

governments;

● differing reimbursement regimes and price controls in certain non-U.S. markets;

● negative consequences from changes in tax laws;

● compliance with tax, employment, immigration and labor laws for employees living or traveling abroad,

including, for example, the variable tax treatment in different jurisdictions of options granted under our share
option schemes or equity incentive plans;

● workforce uncertainty in countries where labor unrest is more common than in the United States;

● litigation or administrative actions resulting from claims against us by current or former employees or

consultants individually or as part of class actions, including claims of wrongful terminations, discrimination,
misclassification or other violations of labor law or other alleged conduct;

● difficulties associated with staffing and managing international operations, including differing labor relations;

● production shortages resulting from any events affecting raw material supply or manufacturing capabilities

abroad; and

● business interruptions resulting from geo-political actions, including war and terrorism, natural disasters,

including earthquakes, typhoons, floods and fires, or public health crises, including outbreaks of COVID-19
or H1N1 flu.

Any or all of these factors could have a material adverse impact on our business, financial condition and results of

operations.

European data collection is governed by restrictive regulations governing the use, processing, and cross-border transfer
of personal information.

The collection and use of personal data (including health-related personal data) in the EEA, is governed by the
provisions of the E.U. General Data Protection Regulation 2016/679, or GDPR, which became effective and enforceable
across all then-current member states of the EEA on May 25, 2018. The GDPR also provides that EEA member states may
make their own national laws and regulations to introduce specific requirements related to the processing of “special
categories of personal data,” including personal data related to health, biometric data used for unique identification
purposes and genetic information, as well as personal data related to criminal offenses or convictions.

The GDPR sets out a number of requirements that must be complied with when handling personal data (i.e.,

 data relating to an identified or identifiable living individual) including: the obligation to appoint a data protection officer 
in certain circumstances; increased accountability and record-keeping obligations; increased transparency obligations for 
data controllers; onerous obligations on service providers who process personal data simply on behalf of others; the 
obligation to carry out so-called data protection impact assessments in certain circumstances; obligations to comply with 
data subjects’ exercise of an increased set of rights in certain circumstances (such as rights for individuals  to be 
“forgotten,” rights to data portability, rights to object, etc., together with express rights to seek legal remedies in the event 
the individual believes his or her rights have been violated); a heightened and more-codified standard of data subject 
consent; and the obligation to notify certain significant personal data breaches to the relevant supervisory authority(ies) and 
affected individuals. In addition, the GDPR materially expanded the definition of what is expressly provided to constitute 
personal data (including, for example, by expressly clarifying that the GDPR applies to “pseudonymized” (i.e., key-coded) 
data, which is often processed by sponsors in the context of clinical trials where identification of underlying subjects is not 
required).

The GDPR has “extra-territorial” reach in that it applies to any controller or process of personal data that 
processes personal data in the context of an establishment in the EEA, or to a controller or processor with no establishment 
in the EEA where their processing concerns the offering of goods or services to individuals in the EEA and/or the 
monitoring of their behavior.  

In addition, European data protection laws, such as the GDPR, generally prohibit the transfer of personal data

from the EEA, and Switzerland to the United States, and most other countries, unless the parties to the transfer have
implemented specific safeguards to protect the transferred personal data. One of the primary safeguards used for transfers
of personal data to the United States was the E.U.-U.S. Privacy Shield framework administered by the U.S. Department of
Commerce. On July 16, 2020, the Court of Justice of the European Union, or CJEU, invalidated the EU-U.S. Privacy
Shield, under which personal data could be transferred from the EEA and the United Kingdom to U.S. entities that had
self-certified under the Privacy Shield. To align with the CJEU’s decision in respect of the E.U.-U.S. Privacy Shield, on
September 8, 2020, the Swiss Federal Data Protection and Information Commissioner announced that the Swiss-U.S.
Privacy Shield regime was also inadequate for the purposes of personal data transfers from Switzerland to the U.S. entities
who had self-certified under the Swiss Privacy Shield.

The CJEU decision referenced above also cast doubt on the ability to use one of the primary alternatives to the

E.U.-U.S. Privacy Shield and Swiss-U.S. Privacy Shield, namely, the European Commission’s Standard Contractual
Clauses, to lawfully transfer personal data to the United States and most other countries. Use of the Standard Contractual
Clauses must now be assessed on a case-by-case basis taking into account the legal regime applicable in the destination
country, in particular applicable surveillance laws and rights of individuals, and additional measures and/or contractual
provisions may need to be put in place; however, the nature of these additional measures is currently uncertain. At present,
there are few if any viable alternatives to the Privacy Shield and the Standard Contractual Clauses. As such, our transfers of
personal data to the United States may not comply with European data protection law and may increase our exposure to the
GDPR’s heightened sanctions for violations of its cross-border data transfer restrictions, including fines of up to 4% of
annual global revenue or €20 million, whichever is higher, and injunctions against transfers. As supervisory authorities
issue further guidance on personal data export mechanisms, including circumstances where the Standard Contractual
Clauses can and cannot be used, and/or start taking enforcement action, we could suffer additional costs, complaints and/or
regulatory investigations or fines, and/or if we are otherwise unable to transfer personal data

79

Table of Contents

between and among countries and regions in which we operate and/or engage providers and/or otherwise transfer personal
data, it could affect the manner in which we receive and/or provide our services, the geographical location or segregation of
our relevant systems and operations, and could adversely affect our financial results and generally increase compliance
risk. Additionally, other countries outside of Europe have enacted or are considering enacting similar cross-border data
transfer restrictions and laws requiring local data residency, which could increase the cost and complexity of operating our
business.

Further, Brexit has created uncertainty regarding data protection regulation in the United Kingdom. Following the 

United Kingdom’s withdrawal from the European Union on January 31, 2020, pursuant to the transitional arrangements 
agreed to between the United Kingdom and European Union, the GDPR continued to have effect in law in the United 
Kingdom, and continued to do so until December 31, 2020 as if the United Kingdom remained a Member State of the 
European Union for such purposes. Following December 31, 2020, and the expiry of those transitional arrangements, the 
data protection obligations of the GDPR continue to apply to United Kingdom-related processing of personal data in 
substantially unvaried form under the so-called “UK GDPR” (i.e., the GDPR as it continues to form part of  law in the 
United Kingdom by virtue of section 3 of the European Union (Withdrawal) Act 2018, as amended (including by the 
various Data Protection, Privacy and Electronic Communications (Amendments etc) (EU Exit) Regulations)). However, 
going forward, there will be increasing scope for divergence in application, interpretation and enforcement of the data 
protection law as between the United Kingdom and EEA. Furthermore, the relationship between the United Kingdom and 
the EEA in relation to certain aspects of data protection law remains somewhat uncertain. For example, it is unclear 
whether transfers of personal data from the EEA to the United Kingdom will be permitted to take place on the basis of a 
future adequacy decision of the European Commission, or whether a “transfer mechanism,” such as the Standard 
Contractual Clauses, will be required. For the meantime, under the Trade and Cooperation Agreement, it has been agreed 
that transfers of personal data to the United Kingdom from European Union Member States will not be treated as 
“restricted transfers” to a non-EEA country for a period of up to four months from January 1, 2021, plus a potential further 
two months extension, or the extended adequacy assessment period. This will also apply to transfers to the United 
Kingdom from EEA Member States, assuming those Member States accede to the relevant provision of the Trade and 
Cooperation Agreement. Although the current maximum duration of the extended adequacy assessment period is six 
months it may end sooner, for example, in the event that the European Commission adopts an adequacy decision in respect 
of the United Kingdom, or the United Kingdom amends the U.K. GDPR and/or makes certain changes regarding data 
transfers under the U.K. GDPR/ Data Protection Act 2018 without the consent of the European Union (unless those 
amendments or decisions are made simply to keep relevant United Kingdom laws aligned with the European Union’s data 
protection regime). If the European Commission does not adopt an ‘adequacy decision’ in respect of the United Kingdom 
prior to the expiry of the extended adequacy assessment period, from that point onwards the United Kingdom will be an 
“inadequate third country” under the GDPR and transfers of data from the EEA to the United Kingdom will require a 
“transfer mechanism,” such as the Standard Contractual Clauses. 

Additionally, as noted above, the United Kingdom has transposed the GDPR into United Kingdom domestic law

by way of the U.K. GDPR with effect from January 2021, which could expose us to two parallel regimes, each of which
potentially authorizes similar fines and other potentially divergent enforcement actions for certain violations (each regime
separately having the ability to fine up to the higher of €20,000,000/£17,000,000 or 4% of an undertaking’s total global
annual turnover). Also, following the expiry of the post-Brexit transitional arrangements, the U.K. Information
Commissioner’s Office is not able to be our “lead supervisory authority” in respect of any “cross border processing” for the
purposes of the GDPR. For so long as we are unable to, and/or do not, designate a lead supervisory authority in an EEA
member state, with effect from January 1, 2021, we are not able to benefit from the GDPR’s “one stop shop” mechanism.
Amongst other things, this would mean that, in the event of a violation of the GDPR affecting data subjects across the
United Kingdom and the EEA, we could be investigated by, and ultimately fined by the United Kingdom Information
Commissioner’s Office and the supervisory authority in each and every EEA member state where data subjects have been
affected by such violation. Other countries have also passed or are considering passing laws requiring local data residency
and/or restricting the international transfer of data.

Exchange rate fluctuations may materially affect our results of operations and financial condition.

Owing to the international scope of our operations, fluctuations in exchange rates, particularly between the pound 

sterling and the U.S. dollar, may adversely affect us.  Although we are based in the United Kingdom, we source 

80

Table of Contents

research and development, manufacturing, consulting and other services from the United States and the European Union 
and Asia that are billed in U.S. dollars.  Further, potential future revenue may be derived from abroad, particularly from the 
United States.  As a result, our business and the price of our ADSs may be affected by fluctuations in foreign exchange 
rates not only between the pound sterling and the U.S. dollar, but also the euro, which may have a significant impact on our 
results of operations and cash flows from period to period.  Currently, we do not have any exchange rate hedging 
arrangements in place.  Any fluctuation in the exchange rate of these foreign currencies may negatively impact our 
business, financial condition and operating results. Global economic events, such as the ongoing COVID-19 pandemic, 
have and may continue to significantly impact local economies and the foreign exchange markets, which may increase the 
risks associated with sales denominated in foreign currencies.

Risks Related to Our Dependence on Third Parties

For certain product candidates, we depend, or will depend, on development and commercialization collaborators to
develop and conduct clinical trials with, obtain regulatory approvals for, and if approved, market and sell product
candidates.  If such collaborators fail to perform as expected, the potential for us to generate future revenue from such
product candidates would be significantly reduced and our business would be harmed.

For certain products candidates, we depend, or will depend, on our development and commercial collaborators to

develop, conduct clinical trials of, and, if approved, commercialize product candidates.

Under our collaborations with Genentech, AstraZeneca, Oxurion, and DDF, we are responsible for identifying and

optimizing Bicycle peptides related to collaboration targets and our collaborators are responsible for further development 
and product commercialization after we complete the defined research screening and compound optimization.  As part of 
our collaboration with Cancer Research Technology Limited and Cancer Research UK, Cancer Research UK Centre for 
Drug Development is sponsoring and funding a Phase I/IIa clinical trial of our lead product candidate, BT1718, in patients 
with advanced solid tumors, and will sponsor and fund development of BT7401 from current preclinical studies through 
the completion of a Phase IIa trial in patients with advanced solid tumors.  We depend on these collaborators to develop 
and, where applicable, commercialize products based on Bicycle peptides, and the success of their efforts directly impacts 
the milestones and royalties we will receive.  We cannot provide assurance that our collaborators will be successful in or 
that they will devote sufficient resources to the development or commercialization of their products.  If our current or 
future collaboration and commercialization partners do not perform in the manner we expect or fail to fulfill their 
responsibilities in a timely manner, or at all, if our agreements with them terminate or if the quality or accuracy of the 
clinical data they obtain is compromised, the clinical development, regulatory approval and commercialization efforts 
related to their and our product candidates and products could be delayed or terminated and it could become necessary for 
us to assume the responsibility at our own expense for the clinical development of such product candidates.

Our current collaborations and any future collaborations that we enter into are subject to numerous risks,

including:

● collaborators have significant discretion in determining the efforts and resources that they will apply to the

collaborations;

● collaborators may not perform their obligations as expected or fail to fulfill their responsibilities in a timely

manner, or at all;

● collaborators may not pursue development and commercialization of any product candidates that achieve

regulatory approval or may elect not to continue or renew development or commercialization programs based
on preclinical studies or clinical trial results, changes in the collaborators’ strategic focus or available funding
or external factors, such as an acquisition, that divert resources or create competing priorities;

● collaborators may delay preclinical studies or clinical trials, provide insufficient funding for clinical trials,

stop a preclinical study or 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;

81

Table of Contents

● we may not have access to, or may be restricted from disclosing, certain information regarding product

candidates being developed or commercialized under a collaboration and, consequently, may have limited
ability to inform our shareholders about the status of such product candidates;

● collaborators could independently develop, or develop with third parties, products that compete directly or

indirectly with our 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;

● the collaborations may not result in product candidates to develop and/or preclinical studies or clinical trials

conducted as part of the collaborations may not be successful;

● product candidates developed with collaborators may be viewed by our collaborators as competitive with
their own product candidates or products, which may cause collaborators to stop commercialization of our
product candidates;

● a collaborator with marketing and distribution rights to one or more of our product candidates that achieve
regulatory approval may not commit sufficient resources to the marketing and distribution of any such
product candidate;

● that the ongoing COVID-19 pandemic

● could materially affect our operations as well as causing significant disruption in the operations and business
of our collaborators and the third-party manufacturers, CROs and other service providers that we and/or our
collaborators conduct business with; and

● 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 intellectual property or
proprietary information or expose us to potential litigation.

In addition, certain collaboration and commercialization agreements provide our collaborators with rights to 

terminate such agreements, which rights may or may not be subject to conditions, and which rights, if exercised, would 
adversely affect our product development efforts and could make it difficult for us to attract new collaborators.  In that 
event, we would likely be required to limit the size and scope of efforts for the development and commercialization of such 
product candidates or products; we would likely be required to seek additional financing to fund further development or 
identify alternative strategic collaborations; our potential to generate future revenue from royalties and milestone payments 
from such product candidates or products would be significantly reduced, delayed or eliminated; and it could have an 
adverse effect on our business and future growth prospects.  Our rights to recover tangible and intangible assets and 
intellectual property rights needed to advance a product candidate or product after termination of a collaboration may be 
limited by contract, and we may not be able to advance a program post-termination.

If conflicts arise with our development and commercialization collaborators or licensors, they may act in their own self-
interest, which may be adverse to the interests of our company.

We may in the future experience disagreements with our development and commercialization collaborators or 
licensors.  Conflicts may arise in our collaboration and license arrangements with third parties due to one or more of the 
following:

● disputes with respect to milestone, royalty and other payments that are believed due under the applicable

agreements;

● disagreements with respect to the ownership of intellectual property rights or scope of licenses;

82

Table of Contents

● disagreements with respect to the scope of any reporting obligations;

● unwillingness on the part of a collaborator to keep us informed regarding the progress of its development and

commercialization activities, or to permit public disclosure of these activities; and

● disputes with respect to a collaborator’s or our development or commercialization efforts with respect to our

products and product candidates.

For example, we were previously involved in litigation with Pepscan Systems B.V., and its affiliates, or Pepscan,

related to a non-exclusive patent license agreement that our subsidiary, BicycleRD Limited, or BicycleRD, entered into
with Pepscan in 2009.

On November 20, 2020, we announced that we entered into a settlement and license agreement with Pepscan
Systems B.V. regarding Bicycle’s use of Pepscan’s CLIPS peptide technology. The companies have agreed to settle all
intellectual property disputes worldwide. Under the terms of the settlement, Bicycle has been granted a license to use
CLIPS peptide technology in the development of its product candidates BT1718 and THR-149. We paid €3 million in
November 2020, will pay €1 million on the first anniversary of the date of settlement, and will make potential additional
payments to Pepscan based on achievement of specified clinical, regulatory and commercial milestones.

Conflicts with our development and commercialization collaborators or licensors could materially adversely affect

our business, financial condition or results of operations and future growth prospects. If we are unable to prevail against
these challenges, our intellectual property estate may be materially harmed, which would impair our ability to establish
competitive barriers to entry in the form of intellectual property protections.

We rely on third parties, including independent clinical investigators and CROs, to conduct and sponsor some of the
clinical trials of our product candidates.  Any failure by a third party to meet its obligations with respect to the clinical
development of our product candidates may delay or impair our ability to obtain regulatory approval for our product
candidates.

We have relied upon and plan to continue to rely upon third parties, including independent clinical investigators, 

academic partners, regulatory affairs consultants and third-party CROs, to conduct our preclinical studies and clinical trials, 
including in some instances sponsoring such clinical trials, and to engage with regulatory authorities and monitor and 
manage data for our ongoing preclinical and clinical programs.  For example, Cancer Research UK currently sponsors and 
funds the Phase I/IIa clinical trial of our lead product candidate, BT1718, in patients with advanced solid tumors.  We also 
utilize CROs to perform toxicology studies related to our preclinical activities.  While we will have agreements governing 
the activities of such third parties, we will control only certain aspects of their activities and have limited influence over 
their actual performance.  Given the breadth of clinical therapeutic areas for which we believe Bicycles may have utility,
we intend to continue to rely on external service providers rather than build internal regulatory expertise.

Any of these third parties may terminate their engagements with us under certain circumstances.  We may not be 

able to enter into alternative arrangements or do so on commercially reasonable terms.  In addition, there is a natural 
transition period when a new contract research organization begins work.  As a result, delays would likely occur, which 
could negatively impact our ability to meet our expected clinical development timelines and harm our business, financial 
condition and prospects.

We remain responsible for ensuring that each of our preclinical studies and clinical trials is conducted in 

accordance with the applicable protocol and legal, regulatory and scientific standards, and our reliance on these third 
parties does not relieve us of our regulatory responsibilities.  We and our third-party contractors and CROs are required to 
comply with GCP requirements, which are regulations and guidelines enforced by the FDA, the Competent Authorities of 
the Member States of the EEA and comparable foreign regulatory authorities for all of our products in clinical 
development.  Regulatory authorities enforce these GCP requirements through periodic inspections of trial sponsors, 
principal investigators and trial sites.  If we fail to exercise adequate oversight over any of our academic partners or CROs 
or if we or any of our academic partners or CROs do not successfully carry out their contractual duties 

83

Table of Contents

or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised 
due to the failure to adhere to our clinical protocols or regulatory requirements, or for any other reasons, the clinical data 
generated in our clinical trials may be deemed unreliable and the FDA, the EMA or comparable foreign regulatory 
authorities may require us to perform additional clinical trials before approving our marketing applications.  We cannot 
assure you that upon a regulatory inspection of us, our academic partners or our CROs or other third parties performing 
services in connection with our clinical trials, such regulatory authority will determine that any of our clinical trials 
complies with GCP regulations.  In addition, our clinical trials must be conducted with product produced under applicable 
CGMP regulations.  Our failure to comply with these regulations may require us to repeat clinical trials, which would delay 
the regulatory approval process.

Furthermore, the third parties conducting clinical trials on our behalf are not our employees, and except for 
remedies available to us under our agreements with such contractors, we cannot control whether or not they devote 
sufficient time, skill and resources to our ongoing development programs.  These contractors may also have relationships 
with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other 
drug development activities, which could impede their ability to devote appropriate time to our clinical programs.  If these 
third parties, including clinical investigators, do not successfully carry out their contractual duties, meet expected deadlines 
or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we may not be able to 
obtain, or may be delayed in obtaining, marketing approvals for our product candidates.  If that occurs, we will not be able 
to, or may be delayed in our efforts to, successfully commercialize our product candidates.

In addition, with respect to investigator-sponsored trials that are being or may be conducted, we do not control the 
design or conduct of these trials, and it is possible that the FDA or EMA will not view these investigator-sponsored trials as 
providing adequate support for future clinical trials or market approval, whether controlled by us or third parties, for any 
one or more reasons, including elements of the design or execution of the trials or safety concerns or other trial results.  We 
expect that such arrangements will provide us certain information rights with respect to the investigator-sponsored trials, 
including the ability to obtain a license to obtain access to use and reference the data, including for our own regulatory 
submissions, resulting from the investigator-sponsored trials.  However, we do not have control over the timing and 
reporting of the data from investigator-sponsored trials, nor do we own the data from the investigator-sponsored trials.  If 
we are unable to confirm or replicate the results from the investigator-sponsored trials or if negative results are obtained, 
we would likely be further delayed or prevented from advancing further clinical development.  Further, if investigators or 
institutions breach their obligations with respect to the clinical development of our product candidates, or if the data proves 
to be inadequate compared to the firsthand knowledge we might have gained had the investigator-sponsored trials been 
sponsored and conducted by us, then our ability to design and conduct any future clinical trials ourselves may be adversely 
affected.  Additionally, the FDA or EMA may disagree with the sufficiency of our right of reference to the preclinical, 
manufacturing or clinical data generated by these investigator-sponsored trials, or our interpretation of preclinical, 
manufacturing or clinical data from these investigator-sponsored trials.  If so, the FDA or EMA may require us to obtain 
and submit additional preclinical, manufacturing, or clinical data.

We intend to rely on third parties to manufacture product candidates, which increases the risk that we will not have
sufficient quantities of such product candidates or products or such quantities at an acceptable cost, which could delay,
prevent or impair our development or commercialization efforts.

We do not own or operate manufacturing facilities for the production of clinical or commercial supplies of the 
product candidates that we are developing or evaluating in our development programs.  We have limited personnel with 
experience in drug manufacturing and lack the resources and the capabilities to manufacture any of our product candidates 
on a clinical or commercial scale.  We rely on third parties for supply of our product candidates, and our strategy is to 
outsource all manufacturing of our product candidates and products to third parties.

In order to conduct clinical trials of product candidates, we will need to have them manufactured in potentially 

large quantities.  Our third-party manufacturers may be unable to successfully increase the manufacturing capacity for any 
of our product candidates in a timely or cost-effective manner, or at all.  In addition, quality issues may arise during scale-
up activities and at any other time.  For example, ongoing data on the stability of our product candidates may shorten the 
expiry of our product candidates and lead to clinical trial material supply shortages, and potentially clinical trial delays.  
Additionally, our manufacturers may experience delays as a result of shelter-in-place, stay-at-home or 

84

Table of Contents

similar orders or other impacts due to the ongoing COVID-19 pandemic.  If our third-party manufacturers are unable to 
successfully scale up the manufacture of our product candidates in sufficient quality and quantity, the development, testing 
and clinical trials of that product candidate may be delayed or infeasible, and regulatory approval or commercial launch of 
that product candidate may be delayed or not obtained, which could significantly harm our business.

Our use of new third-party manufacturers increases the risk of delays in production or insufficient supplies of our 

product candidates as we transfer our manufacturing technology to these manufacturers and as they gain experience 
manufacturing our product candidates.  Even after a third-party manufacturer has gained significant experience in 
manufacturing our product candidates or even if we believe we have succeeded in optimizing the manufacturing process, 
there can be no assurance that such manufacturer will produce sufficient quantities of our product candidates in a timely 
manner or continuously over time, or at all.

We may be delayed if we need to change the manufacturing process used by a third party.  Further, if we change 

an approved manufacturing process, then we may be delayed if the FDA or a comparable foreign authority needs to review 
the new manufacturing process before it may be used.

We operate an outsourced model for the manufacture of our product candidates, and contract with GMP licensed 

pharmaceutical contract development and manufacturing organizations.  While we have engaged several third-party 
vendors to provide clinical and non-clinical supplies and fill-finish services, we do not currently have any agreements with 
third-party manufacturers for long-term commercial supplies.  In the future, we may be unable to enter into agreements 
with third-party manufacturers for commercial supplies of any product candidate that we develop, or may be unable to do 
so on acceptable terms.  Even if we are able to establish and maintain arrangements with third-party manufacturers, 
reliance on third-party manufacturers entails risks, including:

● reliance on third-parties for manufacturing process development, regulatory compliance and quality

assurance;

● limitations on supply availability resulting from capacity and scheduling constraints of third-parties;

● the possible breach of manufacturing agreements by third-parties because of factors beyond our control; and

● the possible termination or non-renewal of the manufacturing agreements by the third-party, at a time that is

costly or inconvenient to us.

Third-party manufacturers may not be able to comply with cGMP requirements or similar regulatory requirements 

outside the United States.  Our failure, or the failure of our third-party manufacturers, to comply with applicable 
requirements could result in sanctions being imposed on us, including fines, injunctions, civil penalties, delays, suspension 
or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions 
and/or criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates.  In 
addition, some of the product candidates we intend to develop, including BT1718, BT5528 and BT8009, use toxins or 
other substances that can be produced only in specialized facilities with specific authorizations and permits, and there can 
be no guarantee that we or our manufacturers can maintain such authorizations and permits.  These specialized 
requirements may also limit the number of potential manufacturers that we can engage to produce our product candidates, 
and impair any efforts to transition to replacement manufacturers.

Our future product candidates and any products that we may develop may compete with other product candidates 
and products for access to manufacturing facilities.  There are a limited number of manufacturers that operate under cGMP 
requirements that might be capable of manufacturing for us.

If the third parties that we engage to supply any materials or manufacture product for our preclinical tests and

clinical trials should cease to continue to do so for any reason, including as a result of the impacts of the ongoing COVID-
19 pandemic on the global workforce and manufacturing operations, we likely would experience delays in advancing these
tests and trials while we identify and qualify replacement suppliers or manufacturers and we may be

85

Table of Contents

unable to obtain replacement supplies on terms that are favorable to us.  In addition, if we are not able to obtain adequate 
supplies of our product candidates or the substances used to manufacture them, it will be more difficult for us to develop 
our product candidates and compete effectively.

Our current and anticipated future dependence upon others for the manufacture of our product candidates may
adversely affect our future profit margins and our ability to develop product candidates and commercialize any products
that receive marketing approval on a timely and competitive basis.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will
discover them or that our trade secrets will be misappropriated or disclosed.

Because we rely on third parties to manufacture our product candidates, and because we collaborate with various 

organizations and academic institutions on the development of our product candidates, we must, at times, share trade 
secrets with them.  We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if 
applicable, material transfer agreements, collaborative research agreements, consulting agreements or other similar 
agreements with our collaborators, advisors, employees and consultants prior to beginning research or disclosing 
proprietary information.  These agreements typically limit the rights of the third parties to use or disclose our confidential 
information, such as trade secrets.

Despite the contractual provisions employed when working with third parties, the need to share trade secrets and 

other confidential information increases the risk that such trade secrets become known by our competitors, are 
inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements.  Given 
that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade 
secrets or other unauthorized use or disclosure would impair our competitive position and may have a material adverse 
effect on our business.

In addition, these agreements typically restrict the ability of our collaborators, advisors, employees and 
consultants to publish data potentially relating to our trade secrets.  Our academic collaborators typically have rights to 
publish data, provided that we are notified in advance and may delay publication for a specified time in order to secure our 
intellectual property rights arising from the collaboration.  In other cases, publication rights are controlled exclusively by 
us, although in some cases we may share these rights with other parties.  Despite our efforts to protect our trade secrets, our 
competitors may discover our trade secrets, either through breach of these agreements, independent development or 
publication of information including our trade secrets in cases where we do not have proprietary or otherwise protected 
rights at the time of publication.  A competitor’s discovery of our trade secrets would impair our competitive position and 
have an adverse impact on our business.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain patent and other intellectual property protection for our products and product
candidates, or if the scope of the patent and other intellectual property protection obtained is not sufficiently broad, our
competitors could develop and commercialize products similar or identical to ours, and our ability to successfully
commercialize our products and product candidates may be adversely affected.

Our ability to compete effectively will depend, in part, on our ability to maintain the proprietary nature of our 

technology and manufacturing processes.  We rely on research, manufacturing and other know-how, patents, trade secrets, 
license agreements and contractual provisions to establish our intellectual property rights and protect our products and 
product candidates.  These legal means, however, afford only limited protection and may not adequately protect our rights.  
As of December 31, 2020, our intellectual property portfolio included four patent families directed to novel scaffolds, 15 
patent families directed to our platform technology, 74 patent families directed to bicyclic peptides and related conjugates, 
and ten patent families directed to methods of using certain bicyclic peptide conjugates for treating various indications.

In certain situations and as considered appropriate, we have sought, and we intend to continue to seek to protect

our proprietary position by filing patent applications in the United States and, in at least some cases, one or more

86

Table of Contents

countries outside the United States relating to current and future products and product candidates that are important to our 
business.  However, we cannot predict whether the patent applications currently being pursued will issue as patents, or 
whether the claims of any resulting patents will provide us with a competitive advantage or whether we will be able to 
successfully pursue patent applications in the future relating to our current or future products and product candidates.  
Moreover, the patent application and approval process is expensive and time-consuming.  We may not be able to file and 
prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner.  Furthermore, we, or any 
future partners, collaborators, or licensees, may fail to identify patentable aspects of inventions made in the course of 
development and commercialization activities before it is too late to obtain patent protection on them.  Therefore, we may 
miss potential opportunities to seek additional patent protection.  It is possible that defects of form in the preparation or 
filing of patent applications may exist, or may arise in the future, for example with respect to proper priority claims, 
inventorship, claim scope, or requests for patent term adjustments.  If we fail to establish, maintain or protect such patents 
and other intellectual property rights, such rights may be reduced or eliminated.  If there are material defects in the form, 
preparation, prosecution or enforcement of our patents or patent applications, such patents may be invalid and/or 
unenforceable, and such applications may never result in valid, enforceable patents.

Even if they are unchallenged, our patents and patent applications, if issued, may not provide us with any 
meaningful protection or prevent competitors from designing around our patent claims by developing similar or alternative 
technologies or therapeutics in a non-infringing manner.  For example, a third party may develop a competitive therapy that 
provides benefits similar to one or more of our product candidates but that falls outside the scope of our patent protection.  
If the patent protection provided by the patents and patent applications we hold or pursue with respect to our product 
candidates is not sufficiently broad to impede such competition, our ability to successfully commercialize our product 
candidates could be negatively affected.

Other parties, many of whom have substantially greater resources and have made significant investments in 

competing technologies, have developed or may develop technologies that may be related or competitive with our 
approach, and may have filed or may file patent applications and may have been issued or may be issued patents with 
claims that overlap or conflict with our patent applications, either by claiming the same compositions, formulations or 
methods or by claiming subject matter that could dominate our patent position.  In addition, the laws of foreign countries 
may not protect our rights to the same extent as the laws of the United States.  As a result, any patents we may obtain in the 
future may not provide us with adequate and continuing patent protection sufficient to exclude others from 
commercializing products similar to our products and product candidates.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain.  No consistent 

policy regarding the breadth of claims allowed in biotechnology and pharmaceutical patents has emerged to date in the 
United States or in many foreign jurisdictions.  In addition, the determination of patent rights with respect to 
pharmaceutical compounds commonly involves complex legal and factual questions, which has in recent years been the 
subject of much litigation.  As a result, the issuance, scope, validity, enforceability and commercial value of our patent 
rights are highly uncertain.  Our competitors may also seek approval to market their own products similar to or otherwise 
competitive with our products.  Alternatively, our competitors may seek to market generic versions of any approved 
products by submitting ANDAs to the FDA in which they claim that our patents are invalid, unenforceable or not 
infringed.  In these circumstances, we may need to defend or assert our patents, or both, including by filing lawsuits 
alleging patent infringement.  In any of these types of proceedings, a court or other agency with jurisdiction may find our 
patents invalid or unenforceable, or that our competitors are competing in a non-infringing manner.  Thus, even if we have 
valid and enforceable patents, these patents still may not provide protection against competing products or processes 
sufficient to achieve our business objectives.

In the future, one or more of our products and product candidates may be in-licensed from third parties.  
Accordingly, in some cases, the availability and scope of potential patent protection is limited based on prior decisions by 
our licensors or the inventors, such as decisions on when to file patent applications or whether to file patent applications at 
all.  Our failure to obtain, maintain, enforce or defend such intellectual property rights, for any reason, could allow third 
parties, in particular, other established and better financed competitors having established development, manufacturing and 
distribution capabilities, to make competing products or impact our ability to develop, manufacture and market our 
products and product candidates, even if approved, on a commercially viable basis, if at all, which could have a material 
adverse effect on our business.

87

Table of Contents

In addition to patent protection, we expect to rely heavily on trade secrets, know-how and other unpatented 
technology, which are difficult to protect.  Although we seek such protection in part by entering into confidentiality 
agreements with our vendors, employees, consultants and others who may have access to proprietary information, we 
cannot be certain that these agreements will not be breached, adequate remedies for any breach would be available, or our 
trade secrets, know-how and other unpatented proprietary technology will not otherwise become known to or be 
independently developed by our competitors.  If we are unsuccessful in protecting our intellectual property rights, sales of 
our products may suffer and our ability to generate revenue could be severely impacted.

Issued patents covering our products and product candidates could be found invalid or unenforceable if challenged in
court or in administrative proceedings.  We may not be able to protect our trade secrets in court.

If we initiate legal proceedings against a third-party to enforce a patent covering one of our products or product 
candidates, should such a patent issue, the defendant could counterclaim that the patent covering our product or product 
candidate 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, including lack of novelty, obviousness, written description or non-enablement.  Grounds for an 
unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld 
information material to patentability from the USPTO, or made a misleading statement, during prosecution.  Third parties 
also may raise similar claims before administrative bodies in the United States or abroad, even outside the context of 
litigation.  Such mechanisms include re-examination, post grant review, inter partes review and equivalent proceedings in 
foreign jurisdictions.  An adverse determination in any of the foregoing proceedings could result in the revocation or 
cancellation of, or amendment to, our patents in such a way that they no longer cover our products or product candidates.  
The outcome following legal assertions of invalidity and unenforceability is unpredictable.  With respect to the validity 
question, for example, we cannot be certain that there is no invalidating prior art, of which the patent examiner and we 
were unaware during prosecution.  If a defendant or third party were to prevail on a legal assertion of invalidity or 
unenforceability, we could lose at least part, and perhaps all, of the patent protection on one or more of our products and 
product candidates.  Such a loss of patent protection may materially harm our intellectual property estate, which would 
impair our ability to establish competitive barriers to entry in the form of intellectual property protections.

In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements 

to protect proprietary know-how that is not patentable or that we elect not to patent, processes for which patents are 
difficult to enforce and any other elements of our product candidate discovery and development processes that involve 
proprietary know-how, information or technology that is not covered by patents.  However, trade secrets can be difficult to 
protect and some courts inside and outside the United States are less willing or unwilling to protect trade secrets.  We seek 
to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with our 
employees, consultants, scientific advisors, and contractors.  We cannot guarantee that we have entered into such 
agreements with each party that may have or have had access to our trade secrets or proprietary technology and processes.  
We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of 
our premises and physical and electronic security of our information technology systems.  While we have confidence in 
these individuals, organizations and systems, agreements or security measures may be breached, and we may not have 
adequate remedies for any breach.

In addition, our trade secrets may otherwise become known or be independently discovered by competitors.  

Competitors and other third parties could purchase our products and product candidates and attempt to replicate some or all 
of the competitive advantages we derive from our development efforts, willfully infringe, misappropriate or otherwise 
violate our intellectual property rights, design around our protected technology or develop their own competitive 
technologies that fall outside of our intellectual property rights.  If any of our trade secrets were to be lawfully obtained or 
independently developed by a competitor or other third party, we would have no right to prevent them, or those to whom 
they communicate it, from using that technology or information to compete with us.  If our trade secrets are not adequately 
protected or sufficient to provide an advantage over our competitors, our competitive position could be adversely affected, 
as could our business.  Additionally, if the steps taken to maintain our trade secrets are deemed inadequate, we may have 
insufficient recourse against third parties for misappropriating our trade secrets.

88

Table of Contents

We may be subject to claims challenging the inventorship or ownership of the patents and other intellectual property.

We may be subject to claims that former employees, collaborators or other third parties have an ownership interest 

in the patents and intellectual property that we own or that we may own or license in the future.  While it is our policy to 
require our employees and contractors who may be involved in the development of intellectual property to execute 
agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each 
party who in fact develops intellectual property that we regard as our own or such assignments may not be self-executing 
or may be breached.  We could be subject to ownership disputes arising, for example, from conflicting obligations of 
employees, consultants or others who are involved in developing our products or product candidates.  Litigation may be 
necessary to defend against any claims challenging inventorship or ownership.  If we fail in defending any such claims, we 
may have to pay monetary damages and may lose valuable intellectual property rights, such as exclusive ownership of, or 
right to use, intellectual property, which could adversely impact our business, results of operations and financial condition.

Obtaining and maintaining patent protection depends on compliance with various procedural, document submission,
fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be
reduced or eliminated for non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and 
applications are required to be paid to the USPTO and various governmental patent agencies outside of the United States in 
several stages over the lifetime of the patents and applications.  The USPTO and various non-U.S. governmental patent 
agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during 
the patent application process and after a patent has issued.  There are situations in which non-compliance can result in 
abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant 
jurisdiction.  The terms of one or more licenses that we enter into the future may not provide us with the ability to maintain 
or prosecute patents in the portfolio, and must therefore rely on third parties to do so.

If we do not obtain patent term extension and data exclusivity for our products and product candidates, our business
may be materially harmed.

Patents have a limited lifespan.  In the United States, if all maintenance fees are timely paid, the natural expiration 
of a patent is generally 20 years from its earliest U.S. non-provisional filing date.  Various extensions may be available, but 
the life of a patent, and the protection it affords, is limited.  Even if patents covering our product candidates are obtained, 
once the patent life has expired for a product candidate, we may be open to competition from competitive products.  Given 
the amount of time required for the development, testing and regulatory review of new product candidates, patents 
protecting such candidates might expire before or shortly after such candidates are commercialized.  As a result, our patent 
portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to 
ours.

In the future, if we obtain an issued patent covering one of our present or future product candidates, depending 
upon the timing, duration and specifics of any FDA marketing approval of such product candidates, such patent may be 
eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, or 
Hatch-Waxman Amendments.  The Hatch-Waxman Amendments permit a patent extension term of up to five years as 
compensation for patent term lost during the FDA regulatory review process.  A patent term extension cannot extend the 
remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent may be extended 
and only those claims covering the approved drug, a method for using it or a method for manufacturing it may be extended.  
A patent may only be extended once and only based on a single approved product.  However, we may not be granted an 
extension because of, for example, failure to obtain a granted patent before approval of a product candidate, failure to 
exercise due diligence during the testing phase or regulatory review process, failure to apply within applicable deadlines, 
failure to apply prior to expiration of relevant patents or otherwise our failure to satisfy applicable requirements.  A patent 
licensed to us by a third party may not be available for patent term extension.  Moreover, the applicable time period or the 
scope of patent protection afforded could be less than we request.  If we are unable to 

89

Table of Contents

obtain patent term extension or the term of any such extension is less than we request, our competitors may obtain approval 
of competing products following our patent expiration, and our revenue could be reduced, possibly materially.

Changes in patent law in the United States and other jurisdictions could diminish the value of patents in general,
thereby impairing our ability to protect our products and product candidates.

Changes in either the patent laws or the interpretation of the patent laws in the United States or other jurisdictions 

could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or 
defense of issued patents.  On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was 
signed into law.  When implemented, the Leahy-Smith Act included several significant changes to U.S. patent law that 
impacted how patent rights could be prosecuted, enforced and defended.  In particular, the Leahy-Smith Act also included 
provisions that switched the United States from a “first-to-invent” system to a “first-to-file” system, allowed third-party 
submission of prior art to the USPTO during patent prosecution and set forth additional procedures to attack the validity of 
a patent by the USPTO administered post grant proceedings.  Under a first-to-file system, assuming the other requirements 
for patentability are met, the first inventor to file a patent application generally will be entitled to the patent on an invention 
regardless of whether another inventor had made the invention earlier.  The USPTO developed new regulations and 
procedures governing the administration of the Leahy-Smith Act, and many of the substantive changes to patent law 
associated with the Leahy-Smith Act, and in particular, the first to file provisions, only became effective on March 16, 
2013.  It remains unclear what, if any, impact the Leahy-Smith Act will have on the operation of our business.  However, 
the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our 
patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect 
on our business.

In addition, the patent positions of companies in the development and commercialization of biologics and 
pharmaceuticals are particularly uncertain.  Recent rulings from the U.S. Court of Appeals for the Federal Circuit and the 
U.S. Supreme Court have narrowed the scope of patent protection available in certain circumstances and weakened the 
rights of patent owners in certain situations.  This combination of events has created uncertainty with respect to the validity 
and enforceability of patents, once obtained.  Depending on future actions by the U.S. Congress, the federal courts, and the 
USPTO, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse 
effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future.

We cannot provide assurance that our efforts to seek patent protection for one or more of our products and product 
candidates will not be negatively impacted by the decisions described above, rulings in other cases or changes in guidance 
or procedures issued by the USPTO.  We cannot fully predict what impact courts’ decisions in historical and future cases 
may have on the ability of life science companies to obtain or enforce patents relating to their products in the future.  These 
decisions, the guidance issued by the USPTO and rulings in other cases or changes in USPTO guidance or procedures 
could have a material adverse effect on our existing patent rights and our ability to protect and enforce our intellectual 
property in the future.

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

Filing, prosecuting, maintaining, defending and enforcing patents on products and product candidates in all 

countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries 
outside the United States could be less extensive than those in the United States.  The requirements for patentability may 
differ in certain countries, particularly in developing countries; thus, even in countries where we do pursue patent 
protection, there can be no assurance that any patents will issue with claims that cover our products.  There can be no 
assurance that we will obtain or maintain patent rights in or outside the United States under any future license agreements.  
In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and 
state laws in the United States.  Consequently, we may not be able to prevent third parties from practicing our inventions in 
all countries outside the United States, even in jurisdictions where we pursue patent protection, or from selling or importing 
products made using our inventions in and into the United States or other jurisdictions.  Competitors may use our 
technologies in jurisdictions where we have not pursued and obtained patent protection to develop their own products and, 
further, may export otherwise infringing products to territories where we have patent protection, but 

90

Table of Contents

enforcement is not as strong as that in the United States.  These products may compete with our products and product 
candidates and our patents or other intellectual property rights may not be effective or sufficient to prevent them from 
competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in 

foreign jurisdictions.  The legal systems of certain countries, particularly certain developing countries, do not favor the 
enforcement of patents, trade secrets and other intellectual property protection, particularly those relating to biotechnology 
and pharmaceutical products, which could make it difficult for us to stop the infringement of our patents or marketing of 
competing products in violation of our proprietary rights generally.  For example, many foreign countries have compulsory 
licensing laws under which a patent owner must grant licenses to third parties.  Proceedings to enforce our patent rights, 
even if obtained, in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other 
aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent 
applications at risk of not issuing and could provoke third parties to assert claims against us.  We may not prevail in any 
lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful.  While 
we intend to protect our intellectual property rights in major markets for our products, we cannot ensure that we will be 
able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market our products.  Accordingly, 
our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant 
commercial advantage from the intellectual property that we develop.

If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time
consuming and could prevent or delay us from developing or commercializing our product candidates.

Our commercial success depends, in part, on our ability to develop, manufacture, market and sell our product 

candidates without infringing the intellectual property and other proprietary rights of third parties.  Third parties may have 
U.S. and non-U.S. issued patents and pending patent applications relating to compounds, methods of manufacturing 
compounds and/or methods of use for the treatment of the disease indications for which we are developing our product 
candidates.  If any third-party patents or patent applications are found to cover our product candidates or their methods of 
use or manufacture, we and our collaborators or sublicensees may not be free to manufacture or market our product 
candidates as planned without obtaining a license, which may not be available on commercially reasonable terms, or at all.  
We may also be required to indemnify our collaborators or sublicensees in such an event.

There is a substantial amount of intellectual property litigation in the biotechnology and pharmaceutical industries, 
and we were previously party to protracted litigation with Pepscan, which we settled in 2020.  We may become party to, or 
be threatened with, litigation or other adversarial proceedings regarding intellectual property rights with respect to our 
products candidates, including interference and post-grant proceedings before the USPTO.  There may be third-party 
patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment 
related to the composition, use or manufacture of our product candidates.  We cannot guarantee that any of our patent 
searches or analyses including, but not limited to, the identification of relevant patents, the scope of patent claims or the 
expiration of relevant patents are complete or thorough, nor can we be certain that we have identified each and every patent 
and pending application in the United States and abroad that is relevant to or necessary for the commercialization of our 
product candidates in any jurisdiction.  Because patent applications can take many years to issue, there may be currently 
pending patent applications which may later result in issued patents that our product candidates may be accused of 
infringing.  In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon 
these patents.  Accordingly, third parties may assert infringement claims against us based on intellectual property rights that 
exist now or arise in the future.  The outcome of intellectual property litigation is subject to uncertainties that cannot be 
adequately quantified in advance.  The pharmaceutical and biotechnology industries have produced a significant number of 
patents, and it may not always be clear to industry participants, including us, which patents cover various types of products 
or methods of use or manufacture.  The scope of protection afforded by a patent is subject to interpretation by the courts, 
and the interpretation is not always uniform.  If we were sued for patent infringement, we would need to demonstrate that 
our product candidates, products or methods either do not infringe the patent claims of the relevant patent or that the patent 
claims are invalid or unenforceable, and we may not be able to do this.  Proving invalidity is difficult.  For example, in the 
United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of 
validity enjoyed by issued patents.  Even if we are successful in these proceedings, we may incur substantial costs and the 
time and attention of our 

91

Table of Contents

management and scientific personnel could be diverted in pursuing these proceedings, which could significantly harm our 
business and operating results.  In addition, we may not have sufficient resources to bring these actions to a successful 
conclusion.

If we are found to infringe a third party’s intellectual property rights, we could be forced, including by court order, 
to cease developing, manufacturing or commercializing the infringing product candidate or product.  Alternatively, we may 
be required to obtain a license from such third party in order to use the infringing technology and continue developing, 
manufacturing or marketing the infringing product candidate or product.  However, we may not be able to obtain any 
required license on commercially reasonable terms or at all.  Even if we were able to obtain a license, it could be non-
exclusive, thereby giving our competitors access to the same technologies licensed to us; alternatively or additionally, it 
could include terms that impede or destroy our ability to compete successfully in the commercial marketplace.  In addition, 
we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have 
willfully infringed a patent.  A finding of infringement could prevent us from commercializing our product candidates or 
force us to cease some of our business operations, which could harm our business.  Claims that we have misappropriated 
the confidential information or trade secrets of third parties could have a similar negative impact on our business.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual
property, or claiming ownership of what we regard as our own intellectual property.

Many of our current and former employees, including our senior management, were previously employed at 

universities or at other biotechnology or pharmaceutical companies, including some which may be competitors or potential 
competitors.  Some of these employees may be subject to proprietary rights, non-disclosure and non-competition 
agreements, or similar agreements, in connection with such previous employment.  Although we try to ensure that our 
employees do not use the proprietary information or know-how of others in their work for us, we have been in the past and 
may be subject in the future to claims that we or these employees have used or disclosed intellectual property, including 
trade secrets or other proprietary information, of any such third party.  Litigation may be necessary to defend against such 
claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual 
property rights or personnel or sustain damages.  Such intellectual property rights could be awarded to a third party, and we 
could be required to obtain a license from such third party to commercialize our technology or products.  Such a license 
may not be available on commercially reasonable terms or at all.  Even if we are successful in defending against such 
claims, litigation could result in substantial costs and be a distraction to management.

In addition, while we typically require our employees, consultants and contractors who may be involved in the 

development of intellectual property to execute agreements assigning such intellectual property to us, we may be 
unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as 
our own, which may result in claims by or against us related to the ownership of such intellectual property.  If we fail in 
prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual 
property rights.  Even if we are successful in prosecuting or defending against such claims, litigation could result in 
substantial costs and be a distraction to our senior management and scientific personnel.

We may become involved in lawsuits to protect or enforce our patents and other intellectual property rights, which could
be expensive, time-consuming and unsuccessful.

Competitors may infringe our patents, trademarks, copyrights or other intellectual property.  To counter 

infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time 
consuming and divert the time and attention of our management and scientific personnel.  In addition, our patents may 
become, involved in inventorship, priority, or validity disputes.  To counter or defend against such claims can be expensive 
and time-consuming, and our adversaries may have the ability to dedicate substantially greater resources to prosecuting 
these legal actions than we can.  Any claims we assert against perceived infringers could provoke these parties to assert 
counterclaims against us alleging that we infringe their patents, in addition to counterclaims asserting that our patents are 
invalid or unenforceable, or both.

92

Table of Contents

In an infringement proceeding, a court may decide that a patent is invalid or unenforceable, or may refuse to stop 
the other party from using the technology at issue on the grounds that our patents do not cover the technology in question.  
Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating 
intellectual property rights we own or control.  An adverse result in any litigation proceeding could put one or more of our 
owned or in-licensed patents at risk of being invalidated or interpreted narrowly.  Further, because of the substantial 
amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential 
information could be compromised by disclosure during this type of litigation.

Even if resolved in our favor, the court may decide not to grant an injunction against further infringing activity 

and instead award only monetary damages, which may or may not be an adequate remedy.  Litigation or other legal 
proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our 
personnel from their normal responsibilities.  In addition, there could be public announcements of the results of hearings, 
motions, or other interim proceedings or developments, and if securities analysts or investors perceive these results to be 
negative, it could have a substantial adverse effect on the price of our ADSs.  Such litigation or proceedings could 
substantially increase our operating losses and reduce the resources available for development activities or any future sales, 
marketing, or distribution activities.

We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately.  

Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can 
because of their greater financial resources and more mature and developed intellectual property portfolios.  Uncertainties 
resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect 
on our ability to compete in the marketplace.

If we fail to comply with our obligations under any future intellectual property licenses with third parties, we could lose
license rights that are important to our business.

In connection with our efforts to build our product candidate pipeline, we may enter into license agreements in the 

future.  We expect that such license agreements will impose, various diligence, milestone payment, royalty, insurance and 
other obligations on us.  If we fail to comply with our obligations under these licenses, our licensors may have the right to 
terminate these license agreements, in which event we might not be able to market any product that is covered by these 
agreements, or our licensors may convert the license to a non-exclusive license, which could negatively impact the value of 
the product candidate being developed under the license agreement.  Termination of these license agreements or reduction 
or elimination of our licensed rights may also result in our having to negotiate new or reinstated licenses with less 
favorable terms.

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

Our trademarks or trade names may be challenged, infringed, circumvented or declared invalid, generic or 
determined to be infringing on other marks.  We rely on both registration and common law protection for our trademarks.  
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.  During trademark 
registration proceedings, we may receive objections.  Although we would be given an opportunity to respond to those 
objections, we may be unable to overcome such objections.  In addition, in the USPTO and in comparable Intellectual 
Property Offices in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark 
applications and to seek to cancel registered trademarks.  Opposition or cancellation proceedings have been and may in the 
future be filed against our trademarks, and our trademarks may not survive such proceedings.  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.

Our UK trademark application for TICA has been opposed by a German company called Immatics

Biotechnologies GmbH. The opposition is based on Immatics Biotechnologies' earlier registered rights for the trademarks
TCER and TiCR which cover similar goods and services. Submissions have been filed by both parties and we are currently
awaiting a decision from the UK IPO.

Risks Related to Employee Matters and Managing Growth

We only have a limited number of employees to manage and operate our business.

As of December 31, 2020, we had 87 full-time or part-time employees.  Our focus on the development of our 
product candidates requires us to optimize cash utilization and to manage and operate our business in a highly efficient 
manner.  We cannot provide assurance that we will be able to hire or retain adequate staffing levels to develop our product 
candidates or run our operations or to accomplish all of the objectives that we otherwise would seek to accomplish.

Cyber-attacks or other failures in telecommunications or information technology systems could result in information
theft, data corruption and significant disruption of our business operations.

We utilize information technology, or IT, systems and networks to process, transmit and store electronic

information in connection with our business activities.  As use of digital technologies has increased, cyber incidents,
including deliberate attacks and attempts to gain unauthorized access to computer systems and networks, have increased in
frequency and sophistication.  These threats pose a risk to the security of our systems and networks, the confidentiality and
the availability and integrity of our data.  In addition, due to the ongoing COVID-19 pandemic, we have enabled our non-
laboratory-based employees to work remotely, which may make us more vulnerable to cyberattacks.  We have been the 
target of cyber-attacks in the past.  For example, in 2019 we were targeted in a phishing incident, which included email 
accounts being accessed by unauthorized third parties.  Promptly after discovery, we performed third-party investigations 
and as there was no evidence of access or acquisition of any personal information as a result of the incident, we believe that 
no further action was required under U.K, E.U. (GDPR) or U.S. federal or state law.  There was no material impact to our 
business or financial condition.  While we believe we responded appropriately, including implementing remedial measures 
to stop the cyber-attacks and with the goal of preventing similar ones in the future, there can be no assurance that we will 
be successful in these remedial and preventative measures or successfully mitigating the effects of future cyber-attacks.  
Similarly, there can be no assurance that our collaborators, CROs, third-party logistics providers, distributors and other 
contractors and consultants will be successful in protecting our clinical and other data that is stored on their systems.  Any 
cyber-attack or destruction or loss of data could have a material adverse effect on our business and prospects.  In addition, 
we may suffer reputational harm or face litigation or adverse regulatory action as a result of cyber-attacks or other data 
security breaches and may incur significant additional expense to respond appropriately to such breaches and to implement 
further data protection measures. We are aware that some public companies have recently received Civil Investigative 
Demands from the Federal Trade Commission, or FTC, requesting information and documents following disclosures of 
privacy or security incidents in SEC filings. The FTC has taken the position that inadequately disclosing privacy and 
security incidents in SEC filings may be a deceptive business practice, and the FTC has relied on SEC filings as a 
launching pad for incident investigations even where the filings were not inadequate.  We cannot be certain that the FTC 
will consider our disclosure adequate or that the FTC will not rely on our disclosure to initiate an incident investigation.

Our future success depends on our ability to retain key employees, consultants and advisors and to attract, retain and
motivate qualified personnel.

We are highly dependent on principal members of our executive team and key employees, the loss of whose 

services may adversely impact the achievement of our objectives.  While we have entered into employment agreements 
with each of our executive officers, any of them could leave our employment at any time.  We do not maintain “key 
person” insurance policies on the lives of these individuals or the lives of any of our other employees.  The loss of the 
services of one or more of our current employees might impede the achievement of our research, development and 
commercialization objectives.  Furthermore, replacing executive officers or other key employees 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 develop, gain marketing approval of and commercialize products successfully.

Recruiting and retaining other qualified employees, consultants and advisors for our business, including scientific 

and technical personnel, will also be critical to our success.  There is currently a shortage of skilled executives 

94

Table of Contents

in our industry, which is likely to continue.  As a result, competition for skilled personnel is intense and the turnover rate 
can be high.  We may not be able to attract and retain personnel on acceptable terms given the competition among 
numerous pharmaceutical and biotechnology companies for individuals with similar skill sets.  In addition, failure to 
succeed in preclinical or clinical trials may make it more challenging to recruit and retain qualified personnel.

In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in 
formulating our research and development and commercialization strategy.  Our consultants and advisors may be employed 
by other entities and may have commitments under consulting or advisory contracts with those entities that may limit their 
availability to us.  If we are unable to continue to attract and retain highly qualified personnel, our ability to develop and 
commercialize our product candidates will be limited.

The inability to recruit or the loss of the services of any executive, key employee, consultant or advisor may

impede the progress of our research, development and commercialization objectives.

Our employees, independent contractors, consultants, collaborators and CROs may engage in misconduct or other
improper activities, including non-compliance with regulatory standards and requirements, which could cause
significant liability for us and harm our reputation.

We are exposed to the risk that our employees, independent contractors, consultants, collaborators and contract 

research organizations may engage in fraudulent conduct or other illegal activity.  Misconduct by those parties could 
include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violates:  (1) FDA 
regulations or similar regulations of comparable non-U.S. regulatory authorities, including those laws requiring the 
reporting of true, complete and accurate information to such authorities, (2) manufacturing standards, (3) federal and state 
healthcare fraud and abuse laws and regulations and similar laws and regulations established and enforced by comparable 
non-U.S. regulatory authorities, and (4) laws that require the reporting of financial information or data accurately.  In 
particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and 
regulations intended to prevent fraud, misconduct, kickbacks, self-dealing, bribery and other abusive practices.  These laws 
and regulations restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, 
customer incentive programs and other business arrangements.  Employee or collaborator misconduct could also involve 
the improper use of, including trading on, information obtained in the course of clinical trials, which could result in 
regulatory sanctions and serious harm to our reputation.  Further, because of the work-from-home policies we implemented 
due to COVID-19, information that is normally protected, including company confidential information, may be less secure.  
In May 2019, we adopted a code of conduct and business ethics, but it is not always possible to identify and deter 
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, standards 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 and results of operations, including the imposition of significant civil, criminal and administrative penalties,
damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare
programs, additional reporting requirements and/or oversight if we become subject to a corporate integrity agreement or
similar agreement to resolve allegations of non-compliance with these laws, imprisonment, contractual damages,
reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could have a
material adverse effect on our ability to operate our business and our results of operations.

We expect to expand our organization, and as a result, we may encounter difficulties in managing our growth, which
could disrupt our operations.

We expect to experience significant growth in the number of our employees and the scope of our operations, 
particularly in the areas of drug manufacturing, regulatory affairs and sales, marketing and distribution, as well as to 
support our public company operations.  To manage these growth activities, we must continue to implement and improve 
our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional 
qualified personnel.  Our management may need to devote a significant amount of its attention to managing these growth 
activities.  Moreover, our expected growth could require us to relocate to geographic areas beyond those where we have 

95

Table of Contents

been historically located.  For example, we maintain office and laboratory space in Cambridge, U.K. and in Lexington, 
Massachusetts, at which many of our finance, management and administrative personnel work.  Due to our limited 
financial resources and the limited experience of our management team in managing a company with such anticipated 
growth, we may not be able to effectively manage the expansion or relocation of our operations, retain key employees, or 
identify, recruit and train additional qualified personnel.  Our inability to manage the expansion or relocation of our 
operations effectively may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business 
opportunities, loss of employees and reduced productivity among remaining employees.  Our expected growth could also 
require significant capital expenditures and may divert financial resources from other projects, such as the development of 
additional product candidates.  If we are unable to effectively manage our expected growth, our expenses may increase 
more than expected, our ability to generate revenues could be reduced and we may not be able to implement our business 
strategy, including the successful commercialization of our product candidates.

Risks Related to Ownership of Our Securities

The market price of our ADSs is highly volatile, and holders of our ADSs may not be able to resell their ADSs at or
above the price at which they purchased their ADSs.

The market price of our ADSs is highly volatile.  Since our initial public offering, or IPO, in May 2019, through 

March 5, 2021, the trading price of our ADSs has ranged from $33.00 to $6.24.  The stock market in general, and the 
market for biopharmaceutical companies in particular, has experienced extreme volatility that has often been unrelated to 
the operating performance of particular companies.  As a result of this volatility, holders of our ADSs may not be able to 
sell their ADSs at or above price at which they purchased their ADSs.  The market price for our ADSs may be influenced 
by many factors, including:

● adverse results or delays in preclinical studies or clinical trials;

● reports of adverse events in products similar or perceived to be similar to those we are developing or clinical

trials of such products;

● an inability to obtain additional funding;

● failure by us to successfully develop and commercialize our product candidates;

● failure by us to maintain our existing strategic collaborations or enter into new collaborations;

● failure by us to identify additional product candidates for our pipeline;

● failure by us or our licensors and strategic partners to prosecute, maintain or enforce our intellectual property

rights;

● changes in laws or regulations applicable to future products;

● changes in the structure of healthcare payment systems;

● an inability to obtain adequate product supply for our product candidates or the inability to do so at

acceptable prices;

● adverse regulatory decisions;

● the introduction of new products, services or technologies by our competitors;

● failure by us to meet or exceed financial projections we may provide to the public;

96

Table of Contents

● failure by us to meet or exceed the financial projections of the investment community;

● the perception of the pharmaceutical industry by the public, legislatures, regulators and the investment

community;

● announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments by

us, our strategic partners or our competitors;

● disputes or other developments relating to proprietary rights, including patents, litigation matters and our

ability to obtain patent protection for our technologies;

● additions or departures of key scientific or management personnel;

● significant lawsuits, including patent or shareholder litigation;

● changes in the market valuations of similar companies;

● sales of our ADSs or ordinary shares by us or our shareholders in the future; and

● the trading volume of our ADSs.

In addition, companies trading in the stock market in general, and Nasdaq in particular, have experienced extreme 

price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these 
companies, including very recently in connection with the ongoing COVID-19 pandemic, which has resulted in decreased 
stock prices for many companies notwithstanding the lack of a fundamental change in their underlying business models or 
prospects.  Broad market and industry factors, including potentially worsening economic conditions and other adverse 
effects or developments relating to the ongoing COVID-19 pandemic, may negatively affect the market price of our ADSs, 
regardless of our actual operating performance.

Concentration of ownership of our ordinary shares (including ordinary shares in the form of ADSs) among our existing
executive officers, directors and principal shareholders may prevent new investors from influencing significant
corporate decisions.

As of December 31, 2020, our executive officers, directors, greater than 5% shareholders and their affiliates 

beneficially own approximately 77.4% of our ordinary shares and ordinary shares in the form of ADSs.  Depending on the 
level of attendance at our general meetings of shareholders, these shareholders either alone or voting together as a group
 could be in a position to determine the outcome of decisions taken at any such general meeting.  Any shareholder or group 
of shareholders controlling more than 50% of the share capital present and voting at our general meetings of shareholders 
may control any shareholder resolution requiring a simple majority, including the appointment of board members, certain 
decisions relating to our capital structure, and the approval of certain significant corporate transactions.  Among other 
consequences, this concentration of ownership may prevent or discourage unsolicited acquisition proposals that holders of 
our ADSs may believe are in their best interest as holders of our ordinary shares or ADSs.  Some of these persons or 
entities may have interests different than current holders of our ordinary shares and ADSs.  For example, because many of 
these shareholders purchased their ordinary shares at prices substantially below the current trading price of our ADSs and 
have held their ordinary shares for a longer period, they may be more interested in selling our company to an acquirer than 
other investors or they may want us to pursue strategies that deviate from the interests of other shareholders.

Future sales, or the possibility of future sales, of a substantial number of our securities could adversely affect the price
of our ADSs and dilute shareholders.

Sales of a substantial number of our ADSs in the public market could occur at any time, subject to certain 

restrictions described below.  If our existing shareholders sell, or indicate an intent to sell, substantial amounts of our 
securities in the public market, the trading price of the ADSs could decline significantly and could decline below the 

97

Table of Contents

current trading prices of the ADSs.  In addition, ordinary shares subject to outstanding options under our equity incentive 
plans and the ordinary shares reserved for future issuance under our equity incentive plans will become eligible for sale in 
the public market in the future, subject to certain legal and contractual limitations.

Moreover, holders of an aggregate of approximately 1,497,905 ordinary shares have rights, subject to conditions,
to require us to file registration statements covering their shares or to include their shares in registration statements that we
may file for ourselves or other shareholders, as well as to cooperate in certain public offerings of such ordinary shares. We
have also registered our ordinary shares that we may issue under our equity compensation plans. These ordinary shares
may be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates.

We have broad discretion in the use of our cash reserves and may not use them effectively.

Our management has broad discretion to use our cash reserves and could use our cash reserves in ways that do not

improve our results of operations or enhance the value of our ordinary shares or ADSs. The failure by our management to
apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause
the price of our ADSs to decline, and delay the development of our product candidates. Pending their use, we may invest
our cash reserves in a manner that does not produce income or that loses value.

Because we do not anticipate paying any cash dividends on our ADSs in the foreseeable future, capital appreciation, if
any, will be the sole source of gains for holders of our ADSs, and they may never receive a return on their investment.

Under current English law, a company’s accumulated realized profits must exceed its accumulated realized losses 

(on a non-consolidated basis) before dividends can be declared and paid.  Therefore, we must have distributable profits 
before declaring and paying a dividend.  In addition, the terms of our indebtedness with Hercules prohibit us from paying 
dividends.  We have not paid dividends in the past on our ordinary shares.  We intend to retain earnings, if any, for use in 
our business and do not anticipate paying any cash dividends in the foreseeable future.  As a result, capital appreciation, if 
any, on our ADSs will be a holder’s sole source of gains for the foreseeable future, and holders will suffer a loss on their 
investment if they are unable to sell their ADSs at or above the original purchase price.

We are an “emerging growth company” and a “smaller reporting company,” and the reduced disclosure requirements
applicable to emerging growth companies and smaller reporting companies may make our ADSs less attractive to
investors.

We are an emerging growth company and we will remain an emerging growth company until the earlier to occur

of (1) the last day of 2024, (2) the last day of the fiscal year in which we have total annual gross revenues of at least
$1.07 billion, (3) the last day of the fiscal year in which we are deemed to be a “large accelerated filer,” under the rules of
the U.S. Securities and Exchange Commission, or SEC, which means the market value of our equity securities that is held
by non-affiliates exceeds $700 million as of the prior June 30th, and (4) the date on which we have issued more than
$1.0 billion in non-convertible debt during the prior three-year period.  For so long as we remain an EGC, we are permitted 
and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are 
not emerging growth companies.  These exemptions include:

● not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley

Act, or Section 404;

● not being required to comply with any requirement that has or may be adopted by the Public Company

Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report
providing additional information about the audit and the financial statements;

● reduced disclosure obligations regarding executive compensation; and

98

Table of Contents

● an exemption from the requirement to seek nonbinding advisory votes on executive compensation or golden

parachute arrangements.

We may choose to take advantage of some, but not all, of the available exemptions.  We cannot predict whether 

investors will find our ADSs less attractive if we rely on certain or all of these exemptions.  If some investors find our 
ADSs less attractive as a result, there may be a less active trading market for our ADSs and our ADS price may be more 
volatile.

In addition, the JOBS Act provides that an EGC may take advantage of an extended transition period for 

complying with new or revised accounting standards.  This allows an EGC to delay the adoption of certain accounting 
standards until those standards would otherwise apply to private companies.  We have irrevocably elected not to avail 
ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the 
relevant dates on which adoption of such standards is required for other public companies.

We are also a smaller reporting company as defined in the Securities Exchange Act of 1934, as amended, or the

Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth
company. We will be a smaller reporting company and may take advantage of the scaled disclosures available to smaller
reporting companies for so long as (i) the market value of our voting and non-voting ordinary shares held by non-affiliates
is less than $250.0 million measured on the last business day of our second fiscal quarter or (ii) (a) our annual revenue is
less than $100.0 million during the most recently completed fiscal year and (b) the market value of our voting and non-
voting ordinary shares held by non-affiliates is less than $700.0 million measured on the last business day of our second
fiscal quarter.

Risks Related to Our Incorporation Under the Laws of England and Wales

Claims of U.S. civil liabilities may not be enforceable against us.

We are incorporated under English law.  Certain members of our board of directors and senior management are 
non-residents of the United States, and all or a substantial portion of our assets and the assets of such persons are located 
outside the United States.  As a result, it may not be possible to serve process on such persons or us in the United States or 
to enforce judgments obtained in U.S. courts against them or us based on civil liability provisions of the securities laws of 
the United States.

The United States and the United Kingdom do not currently have a treaty providing for recognition and 
enforcement of judgments (other than arbitration awards) in civil and commercial matters.  Consequently, a final judgment 
for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not 
automatically be recognized or enforceable in the United Kingdom.  In addition, uncertainty exists as to whether U.K. 
courts would entertain original actions brought in the United Kingdom against us or our directors or senior management 
predicated upon the securities laws of the United States or any state in the United States.  Any final and conclusive 
monetary judgment for a definite sum obtained against us in U.S. courts would be treated by the courts of the United 
Kingdom as a cause of action in itself and sued upon as a debt at common law so that no retrial of the issues would be 
necessary, provided that certain requirements are met.  Whether these requirements are met in respect of a judgment based 
upon the civil liability provisions of the U.S. securities laws, including whether the award of monetary damages under such 
laws would constitute a penalty, is an issue for the court making such decision.  If an English court gives judgment for the 
sum payable under a U.S. judgment, the English judgment will be enforceable by methods generally available for this 
purpose.  These methods generally permit the English court discretion to prescribe the manner of enforcement.

As a result, U.S. investors may not be able to enforce against us or our senior management, board of directors or

certain experts named herein who are residents of the United Kingdom or countries other than the United States any
judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities
laws.

If we are a controlled foreign corporation, there could be adverse U.S. federal income tax consequences to certain U.S.
holders.

Each “Ten Percent Shareholder” (as defined below) in a non-U.S. corporation that is classified as a “controlled
foreign corporation,” or a CFC, for U.S. federal income tax purposes generally is required to include in income for U.S.
federal tax purposes such Ten Percent Shareholder’s pro rata share of the CFC’s “Subpart F income” and investment of 
earnings in U.S. property, even if the CFC has made no distributions to its shareholders.  Subpart F income generally 
includes dividends, interest, rents, royalties, “global intangible low-taxed income,” gains from the sale of securities and 
income from certain transactions with related parties.  In addition, a Ten Percent Shareholder that realizes gain from the 
sale or exchange of shares in a CFC may be required to classify a portion of such gain as dividend income rather than 
capital gain.  A non-U.S. corporation generally will be classified as a CFC for U.S. federal income tax purposes if Ten 
Percent Shareholders own (directly, indirectly or constructively through the application of attribution rules) more than 50%
of either the total combined voting power of all classes of stock of such corporation entitled to vote or of the total value of
the stock of such corporation. A “Ten Percent Shareholder” is a United States person (as defined by the Code) who owns or
is considered to own 10% or more of the total combined voting power of all classes of stock entitled to vote or 10% or
more of the total value of all classes of stock of such corporation.

We believe that we were not a CFC in the 2020 taxable year and we do not expect to be a CFC in the 2021 taxable 

year.  However, the determination of CFC status is complex and includes attribution rules, the application of which is not 
entirely certain.  U.S. Holders (as defined below) should consult their own tax advisors with respect to the potential adverse 
U.S. tax consequences of becoming a Ten Percent Shareholder in a CFC. A “U.S. Holder” is a holder who, for U.S. federal 
income tax purposes, is a beneficial owner of ordinary shares or ADSs and is:

● an individual who is a citizen or individual resident of the United States;

● a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United

States, any state therein or the District of Columbia;

● an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

● a trust if (1) a U.S. court is able to exercise primary supervision over the administration of the trust and one or
more U.S. persons have authority to control all substantial decisions of the trust or (2) the trust has a valid
election in effect to be treated as a U.S. person under applicable U.S. Treasury Regulations.

If we are a passive foreign investment company, there could be adverse U.S. federal income tax consequences to U.S.
holders.

Under the Code, we will be a passive foreign investment company, or PFIC, for any taxable year in which (1) 75%

or more of our gross income consists of passive income or (2) 50% or more of the average quarterly value of our assets 
consists of assets that produce, or are held for the production of, passive income.  For purposes of these tests, passive 
income includes dividends, interest, gains from the sale or exchange of investment property and certain rents and royalties.  
In addition, for purposes of the above calculations, a non-U.S. corporation that directly or indirectly owns at least 25% by 
value of the shares of another corporation is treated as holding and receiving directly its proportionate share of assets and 
income of such corporation.  If we are a PFIC for any taxable year during which a U.S. Holder holds our shares, the U.S. 
Holder may be subject to adverse tax consequences regardless of whether we continue to qualify as a PFIC, including 
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.

Based on our analysis of our income, assets, activities and market capitalization, we believe that we were not a
PFIC in the 2020 taxable year. The determination of whether we are a PFIC is a fact-intensive determination made on an
annual basis applying principles and methodologies that in some circumstances are unclear and subject to varying
interpretation. As a result, there can be no assurance regarding if we will be PFIC or will not be a PFIC in the future. In
addition, the total value of our assets for PFIC testing purposes may be determined in part by reference to the market

100

Table of Contents

price of our ordinary shares or ADSs from time to time, which may fluctuate considerably. Under the income test, our
status as a PFIC depends on the composition of our income which will depend on the transactions we enter into and our
corporate structure.

We may be unable to use net operating loss and tax credit carryforwards and certain built-in losses to reduce future tax
payments or benefit from favorable U.K. tax legislation.

As an entity incorporated and tax resident in the United Kingdom, we are subject to U.K. corporate taxation on 

tax-adjusted trading profits.  Due to the nature of our business, we have generated losses since inception and therefore have 
not paid any U.K. corporation tax.  Subject to numerous utilization criteria and restrictions (including the Corporate 
Income Loss Restriction and the Corporate Capital Loss Restriction that, broadly, restrict the amount of carried forward 
losses that can be utilized to 50% of group profits or gains arising above £5.0 million per tax year, we expect losses to be 
eligible for carry forward and utilization against future operating profits.  In addition, if we were to have a major change in 
the nature of the conduct or the conduct of our trade, loss carryforwards may be restricted or extinguished.

As a group that carries out extensive research and development activities, we seek to benefit from one of two U.K. 
research and development tax relief programs, the Small and Medium-sized Enterprises R&D Tax Credit Program, or SME 
Program, and the Research and Development Expenditure Credit program, or RDEC Program.  Where available, under the 
SME Program, we may be able to surrender the trading losses that arise from our qualifying research and development 
activities for cash or carry them forward for potential offset against future profits (subject to relevant restrictions).  The 
majority of our pipeline research, clinical trials management and manufacturing development activities are eligible for 
inclusion within these SME Program tax credit cash rebate claims. The U.K. government has published draft legislation 
through which it intends to introduce a cap on payable credit claims in excess of £20,000 with effect from April 2021 by 
reference to, broadly, three times the total PAYE and NICs liability of the company, subject to an exception. If such cap 
comes into force, and such exception does not apply, this could restrict the amount of payable credit that we claim. 

We may benefit in the future from the United Kingdom’s “patent box” regime, which allows certain profits 

attributable to revenues from patented products (and other qualifying income) to be taxed at an effective rate of 10%.  We 
are the exclusive licensee or owner of several patent applications which, if issued, would cover our product candidates, and 
accordingly, future upfront fees, milestone fees, product revenues and royalties could be taxed at this tax rate.  When taken 
in combination with the enhanced relief available on our research and development expenditures, we expect a long-term 
lower rate of corporation tax to apply to us.  If, however, there are unexpected adverse changes to the U.K. research and 
development tax credit regime or the “patent box” regime, or for any reason we are unable to qualify for such 
advantageous tax legislation, or we are unable to use net operating loss and tax credit carryforwards and certain built-in 
losses to reduce future tax payments then our business, results of operations and financial condition may be adversely 
affected.

Future changes to tax laws could materially adversely affect our company and reduce net returns to our shareholders.

The tax treatment of the company is, and our ADSs and ordinary shares are, subject to changes in tax laws, 

regulations and treaties, or the interpretation thereof, tax policy initiatives and reforms under consideration and the 
practices of tax authorities in jurisdictions in which we operate, as well as tax policy initiatives and reforms related to the 
Organization for Economic Co-Operation and Development’s, or OECD, Base Erosion and Profit Shifting, or BEPS, 
Project, the European Commission’s state aid investigations and other initiatives.  Such changes may include (but are not 
limited to) the taxation of operating income, investment income, dividends received or (in the specific context of 
withholding tax) dividends paid, or the stamp duty or stamp duty reserve tax treatment of our ADSs or ordinary shares.  We 
are unable to predict what tax reform may be proposed or enacted in the future or what effect such changes would have on 
our business, but such changes, to the extent they are brought into tax legislation, regulations, policies or practices, could 
affect our financial position and overall or effective tax rates in the future in countries where we have operations, reduce 
post-tax returns to our shareholders, and increase the complexity, burden and cost of tax compliance.

Tax authorities may disagree with our positions and conclusions regarding certain tax positions, resulting in
unanticipated costs, taxes or non-realization of expected benefits.

101

Table of Contents

A tax authority may disagree with tax positions that we have taken, which could result in increased tax liabilities.  

For example, while we believe that we operate in compliance with applicable transfer pricing laws and intend to continue
to do so, our transfer pricing procedures are not binding on applicable tax authorities. HM Revenue & Customs, or HMRC, 
the Internal Revenue Service or another tax authority could challenge our allocation of income by tax jurisdiction and the 
amounts paid between our affiliated companies pursuant to our intercompany arrangements and transfer pricing policies, 
including amounts paid with respect to our intellectual property development.  Similarly, a tax authority could assert that 
we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a 
“permanent establishment” under international tax treaties, and such an assertion, if successful, could increase our expected 
tax liability in one or more jurisdictions.  A tax authority may take the position that material income tax liabilities, interest 
and penalties are payable by us, in which case, we expect that we might contest such assessment.  Contesting such an 
assessment may be lengthy and costly and if we were unsuccessful in disputing the assessment, the implications could 
increase our anticipated effective tax rate, where applicable.

Provisions in the U.K. City Code on Takeovers and Mergers that may have anti-takeover effects do not apply to us.

The U.K. City Code on Takeovers and Mergers, or the Takeover Code, applies to an offer for, among other things,

a public company whose registered office is in the United Kingdom if the company is considered by the Panel on
Takeovers and Mergers, or the Takeover Panel, to have its place of central management and control in the United Kingdom
(or the Channel Islands or the Isle of Man). This is known as the “residency test.” The test for central management and
control under the Takeover Code is different from that used by the U.K. tax authorities. Under the Takeover Code, the
Takeover Panel will determine whether we have our place of central management and control in the United Kingdom by
looking at various factors, primarily where the directors are resident.

In September 2019, the Takeover Panel Executive confirmed that, based on our current circumstances, we are not

subject to the Takeover Code. As a result, our shareholders are not entitled to the benefit of certain takeover offer
protections provided under the Takeover Code. We believe that this position is unlikely to change at any time in the near
future but, in accordance with good practice, we will review the situation on a regular basis and consult with the Takeover
Panel if there is any change in our circumstances which may have a bearing on whether the Takeover Panel would
determine our place of central management and control to be in the United Kingdom.

The rights of our shareholders may differ from the rights typically offered to shareholders of a U.S. corporation.

We are incorporated under English law.  The rights of holders of ordinary shares and, therefore, certain of the 

rights of holders of ADSs, are governed by English law, including the provisions of the U.K. Companies Act 2006, or the 
Companies Act, and by our Articles of Association.  These rights differ in certain respects from the rights of shareholders 
in typical U.S. corporations. The principal differences include the following:

● under English law and our articles of association, each shareholder present at a meeting has only one vote 

unless demand is made for a vote on a poll, in which case each holder gets one vote per share owned.  Under 
U.S. law, each shareholder typically is entitled to one vote per share at all meetings;

● under English law, the number of shares determines the number of votes a holder may cast only on a poll.  

However, that the voting rights of ADSs are also governed by the provisions of a deposit agreement with our 
depositary bank;

● under English law, subject to certain exceptions and disapplications, each shareholder generally has 

preemptive rights to subscribe on a proportionate basis to any issuance of ordinary shares or rights to 
subscribe for, or to convert securities into, ordinary shares for cash.  Under U.S. law, shareholders generally 
do not have preemptive rights unless specifically granted in the certificate of incorporation or otherwise;

● under English law and our articles of association, certain matters require the approval of 75% of the 

shareholders who vote (in person or by proxy) on the relevant resolution (or on a poll of shareholders 
representing 75% of the ordinary shares voting (in person or by proxy)), including amendments to the articles 
of association.  This may make it more difficult for us to complete corporate transactions deemed 

102

Table of Contents

advisable by our board of directors.  Under U.S. law, generally only majority shareholder approval is required 
to amend the certificate of incorporation or to approve other significant transactions;

● in the United Kingdom, takeovers may be structured as takeover offers or as schemes of arrangement.  Under 
English law, if we were to be subject to the Takeover Code, a bidder seeking to acquire us by means of a 
takeover offer would need to make an offer for all of our outstanding ordinary shares/ADSs.  If acceptances 
are not received for 90% or more of the ordinary shares/ADSs under the offer, under English law, the bidder 
cannot complete a “squeeze out” to obtain 100% control of us.  Accordingly, acceptances of 90% of our 
outstanding ordinary shares/ADSs will likely be a condition in any takeover offer to acquire us, not 50% as is 
more common in tender offers for corporations organized under Delaware law.  By contrast, a scheme of 
arrangement, the successful completion of which would result in a bidder obtaining 100% control of us, 
requires the approval of a majority of shareholders voting at the meeting and representing 75% of the 
ordinary shares voting, as well as the sanction of the U.K. court;

● under English law and our articles of association, shareholders and other persons whom we know or have 

reasonable cause to believe are, or have been, interested in our shares may be required to disclose information 
regarding their interests in our shares upon our request, and the failure to provide the required information 
could result in the loss or restriction of rights attaching to the shares, including prohibitions on certain 
transfers of the shares, withholding of dividends and loss of voting rights.  Comparable provisions generally 
do not exist under U.S. law; and

● the quorum requirement for a shareholders’ meeting is a minimum of two shareholders entitled to vote at the 
meeting and present in person or by proxy or, in the case of a shareholder that is a corporation, represented by 
a duly authorized officer.  Under U.S. law, a majority of the shares eligible to vote must generally be present 
(in person or by proxy) at a shareholders’ meeting in order to constitute a quorum.  The minimum number of 
shares required for a quorum can be reduced pursuant to a provision in a company’s certificate of 
incorporation or bylaws, but typically not below one-third of the shares entitled to vote at the meeting.

General Risks

Requirements associated with being a public company have increased our costs significantly and have diverted
significant company resources and management attention.

As a U.S. public company, we are incurring and will continue to incur significant legal, accounting and other 

expenses that we did not incur as a private company.  In addition, the Sarbanes-Oxley Act and rules subsequently 
implemented by the SEC and Nasdaq have imposed various requirements on public companies, including establishment 
and maintenance of effective disclosure and financial controls and corporate governance practices.  Our management and 
other personnel currently devote and will continue to devote a substantial amount of time to these compliance initiatives. In 
addition, after we are no longer an EGC, we will incur additional legal accounting and other expenses. If these 
requirements divert the attention of our management and personnel from other business concerns, they could have a 
material adverse effect on our business, financial condition, results of operations, stock price and prospects. The increased 
costs will decrease our net income or increase our net loss and may require us to reduce costs in other areas of our business. 
For example, these rules and regulations have made it more difficult and more expensive for us to obtain director and 
officer liability insurance and we may be required to incur substantial costs to maintain the same or similar coverage. The 
impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our 
board of directors, our board committees or as executive officers.

Pursuant to Section 404, we are required to furnish a report by our management on our internal control over 

financial reporting, including an attestation report on internal control over financial reporting issued by our independent 
registered public accounting firm.  However, while we remain an EGC, and under certain circumstances even after we are 
no longer an EGC, we will not be required to include an attestation report on internal control over financial reporting 
issued by our independent registered public accounting firm.  To achieve compliance with Section 404, we engaged in a 
process to document and evaluate our internal control over financial reporting. We will need to continue to dedicate 
internal resources, and potentially engage outside consultants to continue to assess and document the adequacy of 

103

Table of Contents

internal control over financial reporting, continue steps to improve control processes as appropriate, validate through 
testing that controls are functioning as documented and implement a continuous reporting and improvement process for 
internal control over financial reporting.  Despite our efforts, there is a risk we will not be able to conclude that our internal 
control over financial reporting is effective as required by Section 404.  This could result in an adverse reaction in the 
financial markets due to a loss of confidence in the reliability of our financial statements.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately
report our financial results or prevent fraud.  As a result, shareholders could lose confidence in our financial and other
public reporting, which would harm our business and the trading price of our ADSs.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, 

together with adequate disclosure controls and procedures, are designed to prevent fraud.  Any failure to implement 
required new or improved controls, or difficulties encountered in their implementation could cause us to fail to meet our 
reporting obligations.  In addition, any testing by us conducted in connection with Section 404, or any subsequent testing 
by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial 
reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial 
statements or identify other areas for further attention or improvement.  Inferior internal controls could also cause investors 
to lose confidence in our reported financial information, which could have a negative effect on the trading price of our 
ADSs.

Our management will be required to assess the effectiveness of these controls annually.  However, for as long as 
we are an EGC, our independent registered public accounting firm will not be required to attest to the effectiveness of our 
internal controls over financial reporting pursuant to Section 404.  We could be an EGC for up to five years.  An 
independent assessment of the effectiveness of our internal controls over financial reporting could detect problems that our 
management’s assessment might not.  Undetected material weaknesses in our internal controls over financial reporting 
could lead to financial statement restatements and require us to incur the expense of remediation.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

We are subject to certain reporting requirements of the Exchange Act.  Our disclosure controls and procedures are 

designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the 
Exchange Act is accumulated and communicated to management, recorded, processed, summarized and reported within the 
time periods specified in the rules and forms of the SEC.  We believe that any disclosure controls and procedures or 
internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, 
assurance that the objectives of the control system are met.  These inherent limitations include the realities that judgments 
in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake.  Additionally, controls 
can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized 
override of the controls.  Accordingly, because of the inherent limitations in our control system, misstatements or 
insufficient disclosures due to error or fraud may occur and not be detected.

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against a company following a decline in the 
market price of its securities.  This risk is especially relevant for us because pharmaceutical companies have experienced 
significant stock price volatility in recent years.  If we face such litigation, it could result in substantial costs and a 
diversion of management’s attention and resources, which could harm our business.

An active trading market for our ADSs may not be sustained.

Prior to our IPO in May 2019, there had been no public market for our ADSs.  Although our ADSs are listed on 

The Nasdaq Global Select Market, an active trading market for our shares may not be sustained.  If an active market for our 
ADSs is not sustained, it may be difficult for holders of our ADSs to sell ADSs without depressing the market price for the 
shares, or at all.

104

Table of Contents

An inactive trading market may also impair our ability to raise capital to continue to fund operations by selling

additional shares and may impair our ability to acquire other companies or technologies by using our shares as
consideration.

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

The trading market for our ADSs depends in part on the research and reports that securities or industry analysts 
publish about us or our business.  We do not have any control over these analysts.  Although we have obtained research 
coverage from certain analysts, there can be no assurance that analysts will continue to cover us or provide favorable 
coverage.  If one or more analysts downgrade our ADSs or change their opinion of our ADSs, our ADS price would likely 
decline.  In addition, if one or more analysts cease coverage of our company or fail to regularly publish reports on us, we 
could lose visibility in the financial markets, which could cause our ADS price or trading volume to decline.

ITEM 1B.     UNRESOLVED STAFF COMMENTS.

Not applicable.

ITEM 2.       PROPERTIES.

We occupy approximately 13,500 rentable square feet of office and laboratory space in Cambridge, United

Kingdom under a lease that expires in December 2021, with a five-year extension option, and an additional 11,000 rental
square feet of office and laboratory space in Lexington, Massachusetts under a lease that expires in December 2022, with a
five-year extension option. We believe that our office and laboratory spaces are sufficient to meet our current needs and
that suitable additional space will be available as and when needed.

ITEM 3.       LEGAL PROCEEDINGS.

From time to time, we may become subject to various legal proceedings and claims that arise in the ordinary

course of our business activities. Other than as described below, we are not currently subject to any material legal
proceedings.

License Litigation

In 2009, our subsidiary, BicycleRD Limited, or BicycleRD, entered into a non-exclusive patent license agreement

with Pepscan Systems B.V. and its affiliates, or Pepscan, pursuant to which its licensed rights related to the scaffold used
for Bicycles contained in our lead product candidate, BT1718, which is currently in clinical trial sponsored by Cancer
Research UK, and in THR-149, which has been licensed to Oxurion. The agreement required BicycleRD to enter into a
framework services agreement with Pepscan under which Pepscan would provide certain Bicycles not produced by
BicycleRD. In 2010, BicycleRD entered into such a framework services agreement. In 2015, BicycleRD terminated the
framework services agreement in accordance with its terms. In 2016, Pepscan terminated the patent license agreement.

BicycleRD instituted proceedings in the District Court of The Hague, or the District Court, to contest the right of

Pepscan to terminate the patent license agreement. BicycleRD included a conditional claim for a ruling that the licensed
patent relevant to BicycleRD’s activities is invalid. In response, Pepscan claimed, among other things, that the termination
of the framework services agreement and alleged breaches by BicycleRD of confidentiality obligations constituted grounds
for the termination of the patent license agreement.

Following several years of ongoing litigation and appeals, on February 18, 2020, the Court of Appeal of The

Hague, or the Court of Appeal, ruled that Pepscan was entitled to terminate the license agreement and granted a worldwide
injunction against BicycleRD exploiting the licensed Pepscan patents and any related know-how, subject to a civil daily
fine of EUR 25,000 in the event of non-compliance. BicycleRD subsequently appealed the decision of the Court of Appeal
to the Dutch Supreme Court.

 In September, 2020, BicycleRD filed two petitions requesting inter partes review (IPR) with the Patent Trial and 
Appeal Board of the United States Patent and Trademark Office (USPTO) of two of Pepscan’s U.S. patents forming part of 
the WO 2004 077062 patent family, and a revocation action against the German patent forming part of Pepscan’s WO 2004 
077062 patent family in the German Federal Patent Court.

On November 20, 2020, we announced that we entered into a settlement and license agreement with Pepscan

regarding our use of Pepscan’s CLIPS peptide technology. We and Pepscan have agreed to settle all intellectual property
disputes worldwide, including those described in the preceding paragraphs. Under the terms of the settlement, Pepscan
granted us a license to use CLIPS peptide technology in the development of our product candidates BT1718 and THR-149.
We paid €3 million in November 2020, will pay €1 million on the first anniversary of the date of settlement, and will make
potential additional payments to Pepscan based on achievement of specified clinical, regulatory and commercial
milestones. We also entered into a separate settlement agreement with Pepscan concerning European patent opposition
proceedings, which is described below.

European Patent Opposition Proceedings

In January 2013, Pepscan filed a notice of opposition in respect of European patent 2 257 624, which is a

foundational patent that covers our technology platform. In June 2015, the European Patent Office issued a decision to
maintain this patent as granted and rejecting Pepscan's opposition. Pepscan subsequently filed a notice of appeal to revoke
the patent in its entirety, along with supporting materials. Pursuant to a separate settlement agreement entered into with
Pepscan in November 2020, Pepscan has withdrawn its appeal, and the decision of the Opposition Division maintaining the
patent as granted, for the purposes of the opposition proceedings, has become final.

In April 2015, Pepscan filed a notice of opposition in respect of European patent 2 474 613, which is a divisional 

patent that covers extensions of our technology platform. In February 2017, the European Patent Office issued a decision to 
maintain this patent in an amended form, in which the patent was limited to the use of TBMB scaffolds. Pepscan 
subsequently filed a notice of appeal to revoke the patent in its entirety, along with supporting materials. Concurrently, 
Bicycle also filed a notice of appeal, requesting that the limitation to the use of TBMB be removed. Pursuant to the 
aforementioned separate settlement agreement entered into with Pepscan on November 20, 2020, Pepscan has withdrawn 
its appeal, leaving Bicycle as the sole appellant.  A hearing date has been scheduled for October 5, 2021, at which we plan 
to argue for reversal of the amendments made by the Opposition Division.  The withdrawal of Pepscan’s appeal means that, 
for the purposes of the opposition proceedings, the scope of the patent cannot now be restricted further than the version in 
which it was maintained by the Opposition Division.

In May 2017, the company and Oxurion filed a notice of opposition in respect of Dyax Corp’s European patent 1 

854 477, which contained the following claim 1 (among other claims): “A composition comprising at least one peptide that 
inhibits plasma kallikrein for the use in the treatment of ophthalmic disorders in a patient in need thereof.”  Dyax Corp 
subsequently filed a Main Request to replace the granted claims with a claim scope which was limited to a specific 
consensus sequence.  Oral Proceedings were held on October 15, 2019, and the European Patent Office issued a decision to 
restrict the claims of European patent 1 854 477 to specific peptides and to two specific ophthalmic disorders (namely 
macular oedema and retinal vein occlusion).  Oxurion filed an appeal against this decision at the EPO Technical Board of 
Appeal to challenge any action from Dyax Corp to broaden the current claims.  

In January and February 2019, the company, Oxurion and a further anonymous party filed a notice of opposition 

in respect of Dyax Corp’s European patent 2 374 472, which is a divisional filing of European patent 1 854 477. Claim 1 of 
this divisional patent reads as follows: “A composition comprising at least one plasma kallikrein inhibitor for the use in the 
treatment of an ophthalmic disorder.”  Oral Proceedings before the European Patent Office are scheduled for 11 March 
2021.

Trademark Opposition Proceedings

Our UK trademark application for TICA has been opposed by a German company called Immatics

Biotechnologies GmbH. The opposition is based on Immatics Biotechnologies' earlier registered rights for the trademarks
TCER and TiCR which cover similar goods and services. Submissions have been filed by both parties and we are currently
awaiting a decision from the UK IPO.

PART II

ITEM 5.       MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS

AND ISSUER PURCHASES OF EQUITY SECURITIES.

Market Information

Our ordinary shares, par value £0.01 per share, are not publicly traded. Our American Depositary Shares, or 
ADSs, each represent one ordinary share of Bicycle Therapeutics plc and began trading on The Nasdaq Global Select 
Market on May 23, 2019 under the symbol “BCYC.”  Prior to that date, there was no public trading market for our ADSs 
or our ordinary shares.  

Holders of Ordinary Shares

As of March 5, 2021, there were approximately 73 holders of record of our ordinary shares and one holder of record of our
ADSs. The number of beneficial owners of the ADSs in the United States is likely to be much larger than the number of
record holders of our ordinary shares in the United States.

Recent Sales of Unregistered Equity Securities

None.

Use of Proceeds from Registered Securities

On May 28, 2019, we completed our IPO of 4,333,333 ADSs at a public offering price of $14.00 per ADS for an 

aggregate offering price of approximately $60.7 million. In addition, in June 2019, we issued 304,333 ADSs at a public 
offering price of $14.00 per ADS for an aggregate offering price of approximately $4.3 million in connection with the 
underwriters’ partial exercise of their option to purchase additional ADSs.  Goldman Sachs & Co. LLC, Jefferies LLC, 
Piper Jaffray & Co. and Canaccord Genuity LLC served as the underwriters of the IPO.  The offer and sale of all of the 
ADSs in the offering were registered under the Securities Act pursuant to a registration statement on Form S-1 (File No. 
333-231076), which was declared effective by the SEC on May 22, 2019.

We received aggregate net proceeds from the offering of approximately $56.4 million, after deducting

underwriting discounts and commissions of $4.5 million and offering expenses of $4.0 million. No offering expenses were
paid directly or indirectly to any of our directors or officers (or their associates) or persons owning 10% or more of any
class of our equity securities or to any other affiliates.

There has been no material change in our planned use of the net proceeds from the offering as described in the
final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act. As of December 31, 2020, we had
consumed all of the net proceeds from the IPO, primarily to advance our BT1718, BT5528, BT8009, BT7480, and other
discovery development programs, as well as for continued drug discovery efforts and translational research activities, and
for working capital and other general corporate purposes.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

None.

ITEM 7.       MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS

OF OPERATIONS.

You should read this discussion and analysis of our financial condition and consolidated results of operations

together with the consolidated financial statements, related notes and other financial information included 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 statements of our plans, objectives, expectations and intentions, contain 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 the forward-looking statements contained in the following discussion and analysis. Please also
see the section titled “Forward-Looking Statements.”

For the discussion of the financial condition and results of operations for the year ended December 31, 2019

compared to the year ended December 31, 2018, refer to "Management's Discussion and Analysis of Financial Condition
and Results of Operations—Results of Operations" and "—Liquidity and Capital Resources" included in the Company’s
Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the Securities and Exchange
Commission, or the SEC, on March 10, 2020.

Overview

We are a clinical-stage biopharmaceutical company developing a novel class of medicines, which we refer to as
Bicycles, for diseases that are underserved by existing therapeutics. Bicycles are fully synthetic short peptides constrained
to form two loops which stabilize their structural geometry. This constraint facilitates target binding with high affinity and
selectivity, making Bicycles attractive candidates for drug development. Bicycles are a unique therapeutic modality
combining the pharmacology usually associated with a biologic with the manufacturing and pharmacokinetic, or PK,
properties of a small molecule. The relatively large surface area presented by Bicycles allow targets to be drugged that have
historically been intractable to non-biological approaches. Bicycles are excreted by the kidney rather than the liver and
have shown no signs of immunogenicity to date, which we believe together support a favorable toxicological profile.

We have a novel and proprietary phage display screening platform which we use to identify Bicycles in an

efficient manner. The platform initially displays linear peptides on the surface of engineered bacteriophages, or phages,
before “on-phage” cyclization with a range of small molecule scaffolds which can confer differentiated physicochemical
and structural properties. Our platform encodes quadrillions of potential Bicycles which can be screened to identify
molecules for optimization to potential product candidates. We have used this powerful screening technology to identify
our current portfolio of candidates in oncology and intend to use it in conjunction with our collaborators to seek to develop
additional future candidates across a range of other disease areas.

Our initial internal programs are focused on oncology indications with high unmet medical need. Our lead product

candidates, BT1718, BT5528 and BT8009, are Bicycle Toxin Conjugates®, or BTCs. These Bicycles are chemically
attached to a toxin that when administered is cleaved from the Bicycle® and kills the tumor cells. BT1718 is being 
developed to target tumors that express Membrane Type 1 matrix metalloproteinase, or MT1 MMP and is being 
investigated for safety, tolerability and efficacy in an ongoing Phase I/IIa clinical trial in collaboration with, and fully 
funded by, the Cancer Research UK Centre for Drug Development, or Cancer Research UK. We are also evaluating 
BT5528, a second-generation BTC targeting Ephrin type A receptor 2, or EphA2, in a company-sponsored Phase I/II 
clinical trial as a monotherapy and in combination with nivolumab, and BT8009, a second-generation BTC targeting 
Nectin-4, in a company-sponsored Phase I/II clinical trial.  Our discovery pipeline in oncology includes Bicycle-based
systemic immune cell agonists and Bicycle tumor-targeted immune cell agonists, or TICAs.

Beyond our wholly-owned oncology portfolio, we are collaborating with biopharmaceutical companies and

organizations in therapeutic areas in which we believe our proprietary Bicycle screening platform can identify therapies

110

Table of Contents

to treat diseases with significant unmet medical need. Our partnered programs outside of oncology include collaborations
in immuno-oncology, anti-infective, cardiovascular, ophthalmology, dementia and respiratory indications.

Financial Overview

Since our inception, we have devoted substantially all of our resources to developing our Bicycle platform and our

product candidates, BT1718, BT5528, BT8009, BT7480, BT7455, and BT7401, conducting research and development of
our product candidates and preclinical programs, raising capital and providing general and administrative support for our
operations. To date, we have financed our operations primarily with proceeds from the sale of our American Depositary
Shares, or ADSs, ordinary shares, and convertible preferred shares, proceeds received from upfront payments, research and
development payments, and development milestone payments from our collaboration agreements with Genentech Inc., or
Genentech, Oxurion NV (formerly ThromboGenics NV), or Oxurion, AstraZeneca AB, or AstraZeneca, Sanofi and the
Dementia Discovery Fund, or DDF; and borrowings pursuant to our debt facility with Hercules Capital, Inc., or Hercules.
From our inception in 2009 through December 31, 2020, we have received gross proceeds of $243.4 million from the sale
of ADSs, ordinary shares and convertible preferred shares, including the proceeds from our initial public offering and at-
the-market, or ATM, offering program; and $63.1 million of cash payments under our collaboration revenue arrangements,
including $31.0 million from Genentech, $10.3 million from AstraZeneca, $4.1 million from Oxurion, $15.0 million from
Sanofi, $1.7 million from DDF; and $15.0 million of borrowings pursuant to our Loan and Security Agreement, or Loan
Agreement with Hercules. In January 2021, we received $2.4 million from Oxurion due to a milestone achieved for the
initiation of a Phase II trial of THR-149 and $3.0 million of proceeds under an evaluation and option agreement. We do not
have any products approved for sale and have not generated any revenue from product sales.

Since our inception, we have incurred significant operating losses. Our ability to generate product revenue

sufficient to achieve profitability will depend on the successful development and eventual commercialization of one or
more of our product candidates. Our net losses were $51.0 million, $30.6 million and $21.8 million for the years ended
December 31, 2020, 2019 and 2018, respectively. As of December 31, 2020, we had an accumulated deficit of
$151.6 million. These losses have resulted primarily from costs incurred in connection with research and development
activities and general and administrative costs associated with our operations. We expect to continue to incur significant
expenses and increasing operating losses for the foreseeable future.

We anticipate that our expenses and capital requirements will increase substantially in connection with our

ongoing activities, particularly as we advance the preclinical activities and clinical trials of our product candidates and, if
any product candidates are approved, pursue the commercialization of such product candidates by building internal sales
and marketing capabilities. We expect that our expenses and capital requirements will increase substantially if and as we:

● continue our development of our product candidates, including conducting future clinical trials of BT1718,

BT5528 and BT8009;

● progress the preclinical and clinical development of BT7480, BT7455 and BT7401;

● seek to identify and develop additional product candidates;

● develop the necessary processes, controls and manufacturing data to obtain marketing approval for our

product candidates and to support manufacturing to commercial scale;

● develop, maintain, expand and protect our intellectual property portfolio;

● seek marketing approvals for our product candidates that successfully complete clinical trials, if any;

111

Table of Contents

● hire and retain additional personnel, such as non-clinical, clinical, pharmacovigilance, quality assurance,

regulatory affairs, manufacturing, distribution, legal, compliance, medical affairs, commercial and scientific
personnel;

● acquire or in-license other products and technologies;

● expand our infrastructure and facilities to accommodate our growing employee base, including adding

equipment and infrastructure to support our research and development; and

● add operational, financial and management information systems and personnel, including personnel to

support our research and development programs, any future commercialization efforts and our operations as a
public company.

We do not expect to generate revenue from product sales unless and until we successfully complete development

and obtain marketing approval for one or more of our product candidates, which we expect will take many years and is
subject to significant uncertainty. We have no commercial-scale manufacturing facilities of our own, and all of our
manufacturing activities have been and are planned to be contracted out to third parties. Additionally, we currently utilize
third-party contract research organizations, or CROs, to carry out our clinical development activities. If we seek to obtain
marketing approval for any of our product candidates from which we obtain promising results in clinical development, we
expect to incur significant commercialization expenses as we prepare for product sales, marketing, manufacturing, and
distribution.

As a result, we will need substantial additional funding to support our continuing operations and pursue our 

growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance 
our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances, charitable 
grants, monetization transactions or licensing arrangements. We may be unable to raise additional funds or enter into such 
other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such 
agreements as, and when, needed, we may have to significantly delay, scale back, or discontinue the development and 
commercialization of one or more of our product candidates. The COVID-19 pandemic has already resulted in a significant 
disruption of global financial markets.  If the disruption persists and deepens, whether as a result of the ongoing COVID-19 
pandemic or otherwise, we could experience an inability to access additional capital.

Because of the numerous risks and uncertainties associated with product development, we are unable to predict
the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we
are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain
profitability on a continuing basis, we may be unable to continue our operations at planned levels and be forced to reduce
or terminate our operations.

As of December 31, 2020, we had cash of $136.0 million. We believe that our existing cash will enable us to fund

our operating expenses and capital expenditure requirements for at least 12 months from the date of filing of this Annual
Report on Form 10-K. We have based this estimate on assumptions that may prove to be wrong, and we could deplete our
available capital resources sooner than we expect. See “— Liquidity and Capital Resources.”

Components of Our Results of Operations

Collaboration Revenues

To date, we have not generated any revenue from product sales and we do not expect to generate any revenue

from product sales for the foreseeable future. Our revenue primarily consists of collaboration revenue under our
arrangements with our collaboration partners, including amounts that are recognized related to upfront payments, milestone
payments and option exercise payments, and amounts due to us for research and development services. In the future,
revenue may include additional milestone payments and option exercise payments, and royalties on any net product sales
under our collaborations. We expect that any revenue we generate will fluctuate from period to period as a result of the
timing and amount of license, research and development services, milestone and other payments.

112

Table of Contents

Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research and development

activities, including our discovery efforts, and the development of our product candidates, which include:

● employee-related expenses including salaries, benefits, and share-based compensation expense;

● expenses incurred under agreements with third parties that conduct research and development, preclinical

activities, clinical activities and manufacturing on our behalf;

● the cost of consultants;

● the cost of lab supplies and acquiring, developing and manufacturing preclinical study materials and clinical

trial materials;

● costs related to compliance with regulatory requirements; and

● facilities, depreciation, and other expenses, which include direct and allocated expenses for rent and

maintenance of facilities, and other operating costs.

Research and development costs are expensed as incurred. Costs for certain activities 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 our consolidated financial
statements as a prepaid expense or accrued research and development expenses. Nonrefundable advance payments for
goods or services to be received in the future for use in research and development activities are capitalized. The capitalized
amounts are expensed as the related goods are delivered or the services are performed.

U.K. research and development tax credits and government grant funding are recorded as an offset to research and

development expense. See “—Benefit from Income Taxes.”

Our direct external research and development expenses are tracked on a program-by-program basis and consist of
costs, such as fees paid to consultants, contractors and contract manufacturing organizations, or CMOs, in connection with
our preclinical and clinical development activities. Costs incurred after a product candidate has been designated and that
are directly related to the product candidate are included in direct research and development expenses for that program.
Costs incurred prior to designating a product candidate are included in other discovery and platform related expense. We do
not allocate employee costs, costs associated with our discovery efforts, laboratory supplies, and facilities, including
depreciation or other indirect costs, to specific product development programs because these costs are deployed across
multiple product development programs and, as such, are not separately classified.

In December 2016, we entered into a Clinical Trial and License Agreement with Cancer Research Technology

Limited, or CRTL and Cancer Research UK, pursuant to which the Cancer Research UK Centre for Drug Development is
sponsoring and funding a Phase I/IIa clinical trial for our product candidate, BT1718, in patients with advanced solid
tumors. Cancer Research UK has designed and prepared and is carrying out and sponsoring the clinical trial at its own cost.
Upon the completion of the Phase I/IIa clinical trial, we have the right to obtain a license to the results of the clinical trial
upon the payment of a milestone, in cash and ordinary shares, with a combined value in the mid six digit dollar amount. If
such license is not acquired, or if it is acquired and the license is terminated and we decide to abandon development of all
products that deliver cytotoxic payloads to the MT1 target antigen, CRTL may elect to receive an assignment and exclusive
license to develop and commercialize the product on a revenue sharing basis (in which case we will receive tiered royalties
of 70% to 90% of the net revenue depending on the stage of development when the license is granted is less certain costs,
as defined in the agreement). The Cancer Research UK Agreement contains additional future milestone payments upon the
achievement of development, regulatory and commercial milestones,

113

Table of Contents

payable in cash and shares, with an aggregate total value of $50.9 million, as well as royalty payments based on a single
digit percentage on net sales of products developed. The Cancer Research UK Agreement can be terminated by either party
upon an insolvency event, material breach of the terms of the contract, upon a change in control involving a tobacco related
entity, and in certain other specified circumstances, and includes provisions that require the repayment of costs to Cancer
Research UK upon certain termination events or change in control events. The costs incurred by Cancer Research UK are
recorded as a liability in accordance with ASC 730, Research and Development as the payments are not based solely on the
results of the research and development having future economic benefit. The liability is recorded as incremental research
and development expense in the consolidated statements of operations and comprehensive loss. Upon the completion of the
Phase IIa part of the clinical trial, we expect research and development expenses to increase significantly as we expect to
fund the continued development of BT1718, as well as incur additional development milestone payments.

Research and development activities are central to our business model. 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 that our research and development
expenses will continue to increase for the foreseeable future as a result of our expanded portfolio of product candidates and
as we: (i) continue the clinical development and seek to obtain marketing approval for our product candidates, including
BT1718, BT5528 and BT8009; (ii) initiate clinical trials for our product candidates, including BT7480, BT7455 and
BT7401; and (iii) build our in-house process development and analytical capabilities and continue to discover and develop
additional product candidates.

The successful development of our product candidates is highly uncertain. As such, at this time, we cannot

reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the
remainder of the development of these product candidates. We are also unable to predict when, if ever, material net cash
inflows will commence from our product candidates. This is due to the numerous risks and uncertainties associated with
developing products, including the uncertainty of:

● whether our business will be adversely affected by the ongoing COVID-19 pandemic, which could materially
affect our operations, delay our research efforts and clinical trials and cause significant disruption in the
operations and business of third-party manufacturers, contract research organizations, or CROs, other service
providers, and collaborators with whom we conduct business; and

● completing research and preclinical development of our product candidates, including conducting future

clinical trials of BT1718, BT5528 and BT8009;

● progressing the preclinical and clinical development of BT7480, BT7455 and BT7401;

● establishing an appropriate safety profile with IND-enabling studies to advance our preclinical programs into

clinical development;

● identifying new product candidates to add to our development pipeline;

● successful enrollment in, and the initiation and completion of clinical trials;

● the timing, receipt and terms of any marketing approvals from applicable regulatory authorities;

● commercializing the product candidates, if and when approved, whether alone or in collaboration with others;

● establishing commercial manufacturing capabilities or making arrangements with third party manufacturers;

114

Table of Contents

● the development and timely delivery of commercial-grade drug formulations that can be used in our clinical

trials;

● addressing any competing technological and market developments, as well as any changes in governmental

regulations;

● negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter

and performing our obligations under such arrangements;

● maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade

secrets and know-how, as well as obtaining and maintaining regulatory exclusivity for our product
candidates;

● continued acceptable safety profile of the drugs following approval; and

● attracting, hiring and retaining qualified personnel.

A change in the outcome of any of these variables with respect to the development of a product candidate could 

mean a significant change in the costs and timing associated with the development of that product candidate. For example, 
the FDA, EMA or another regulatory authority may require us to conduct clinical trials beyond those that we anticipate will 
be required for the completion of clinical development of a product candidate, or we may experience significant trial delays 
due to patient enrollment or other reasons, including the impacts of the ongoing COVID-19 pandemic, in which case we 
would be required to expend significant additional financial resources and time on the completion of clinical development. 
For instance, all clinical sites for the Phase I/IIa trial of BT1718 being conducted by Cancer Research UK in the United 
Kingdom temporarily paused enrollment of new patients due to the ongoing COVID-19 pandemic during the first half of 
2020. The pause in enrollment was lifted in the second quarter of 2020, and patient enrollment in the Phase IIa portion of 
the clinical trial is again underway.  However, changes in circumstances related to the ongoing pandemic could result in 
future pauses in or other impacts on enrollment. In addition, we may obtain unexpected results from our clinical trials, and 
we may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. 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. 

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including share-based
compensation, for personnel in our executive, finance, corporate and business development and administrative functions.
General and administrative expenses also include professional fees for legal, patent, accounting, auditing, tax and
consulting services, insurance, travel expenses and facility-related expenses, which include direct depreciation costs and
allocated expenses for rent and maintenance of facilities and other operating costs.

Foreign currency transactions in currencies different from the functional currency of our UK entities are translated

into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange
differences resulting from the settlement of such transactions and from the translation at period-end exchange rates in
foreign currencies are recorded in general and administrative expense in the statement of operations and comprehensive
loss. As such, our operating expenses may be impacted by future changes in exchange rates. See “Quantitative and
Qualitative Disclosures About Market Risks” for further discussion.

We expect that our general and administrative expenses will increase in the future as we increase our general and

administrative headcount to support our continued research and development and potential commercialization of our
portfolio of product candidates. We also expect to incur increased expenses associated with being a public company,

115

Table of Contents

including costs of accounting, audit, information systems, legal, intellectual property, regulatory and tax compliance
services, director and officer insurance costs and investor and public relations costs.

Other Income (Expense)

Interest Income

Interest income consists primarily of interest earned on our cash held in operating accounts.

Interest Expense

Interest expense consists primarily of interest expense for financing arrangements. On September 30, 2020, we 

entered into the Loan Agreement with Hercules and borrowed $15.0 million.  Consequently, we expect interest expense to 
increase in future periods.

 Other Expense, net

Prior to our IPO, other expense, net consisted primarily of changes in the fair value associated with the
remeasurement of the warrant liability for warrants we issued to subscribe for Series A and Series B1 convertible preferred
shares. We remeasured the warrant liability at fair value at each reporting period until completion of our IPO in May 2019.
Upon the completion of the IPO, the respective warrants were exercised or converted to warrants to subscribe for ordinary
shares, and as such, we will not incur additional expense related to the remeasurement of the warrant liability in future
periods.

Benefit From Income Taxes

We are subject to corporate taxation in the United States and the United Kingdom. We have generated losses since

inception and have therefore not paid United Kingdom corporation tax. The benefit from income taxes presented in our
consolidated statements of operations and comprehensive loss represents the tax impact from our operating activities in the
United States, which have generated taxable income based on intercompany service arrangements.

The research and development tax credit received in the United Kingdom is recorded as a reduction to research
and development expenses. The U.K. research and development tax credit, as described below, is fully refundable to us
after surrendering tax losses and is not dependent on current or future taxable income. As a result, we have recorded the
entire benefit from the U.K. research and development tax credit as a reduction to research and development expenses and
is not reflected as part of the income tax provision. If, in the future, any U.K. research and development tax credits
generated are needed to offset a corporate income tax liability in the United Kingdom, that portion would be recorded as a
benefit within the income tax provision and any refundable portion not dependent on taxable income would continue to be
recorded as a reduction to research and development expenses.

As a company that carries out extensive research and development activities, we seek to benefit from one of two
U.K. research and development tax credit cash rebate regimes: The Small and Medium-sized Enterprises R&D Tax Credit
Program, or SME Program, and the Research and Development Expenditure program, or RDEC Program. Qualifying
expenditures largely comprise employment costs for research staff, consumables expenses incurred under agreements with
third parties that conduct research and development, preclinical activities, clinical activities and manufacturing on our
behalf and certain internal overhead costs incurred as part of research projects.

Based on criteria established by U.K. law, a portion of expenditures being carried out in relation to our pipeline

research and development, clinical trials management and manufacturing development activities were eligible for the
RDEC Program for the year ended December 31, 2020. We will assess whether it is possible to qualify under the more
favorable SME regime for future accounting periods, but this will be affected as a result of becoming a large company by
reference to our staff headcount and/or our financial results.

116

Table of Contents

Unsurrendered U.K. losses may be carried forward indefinitely to be offset against future taxable profits, subject
to numerous utilization criteria and restrictions. The amount that can be offset each year is limited to £5.0 million plus an
incremental 50% of U.K. taxable profits. After accounting for tax credits receivable, we had accumulated tax losses for
carry forward in the United Kingdom of $72.0 million and $41.7 million as of December 31, 2020 and 2019, respectively.

Value Added Tax, or VAT, is broadly charged on all taxable supplies of goods and services by VAT-registered

businesses. Under current rates, an amount of 20% of the value, as determined for VAT purposes, of the goods or services
supplied is added to all sales invoices and is payable to HMRC. Similarly, VAT paid on purchase invoices is generally
reclaimable from HMRC and is included as a component of prepaid and other current assets in our consolidated balance
sheets.

Collaboration Revenues

Collaboration revenues decreased by $3.4 million during the year ended December 31, 2020 compared to the year

ended December 31, 2019, primarily due to a decrease of $10.7 million of revenue from our collaboration with Sanofi. In
March 2019, Sanofi exercised its right to terminate the sickle cell program and in October 2019, Sanofi terminated the
hemophilia program, resulting in the recognition of revenue of $5.3 million and $4.7 million, respectively, for amounts
allocated to material rights when these options expired, as well as a decrease in revenue of $1.0 million related to a one-
time payment pursuant to a Material Transfer Agreement in 2019. These amounts were offset by an increase of $4.9
million of revenue from our collaboration with Genentech entered into in 2020, an increase of $2.4 million of revenue from
a collaboration arrangement with Oxurion due to a milestone achieved for the initiation of a Phase II trial of THR-149, and
$1.0 million of revenue from our collaboration arrangement with AstraZeneca primarily as AstraZeneca exercised its right
to terminate a collaboration program, which resulted in the recognition of revenue of $1.5 million for amounts allocated to
a material right when an option expired.

Research and development expense increased by $7.6 million in the year ended December 31, 2020 as compared
to the year ended December 31, 2019, primarily due to increases of $5.8 million in direct program spend, primarily due to
increased clinical and TICA program development expenses offset by a $0.6 million decrease in other unallocated
discovery and platform expense due to the timing of development activities, as well as an increase of $2.8 million in
employee and contractor related expenses attributable to increased headcount and $1.3 million of incremental share-based
compensation expense, offset by a $2.4 million increase in the research and development tax credit reimbursement due to
the corresponding increase in research and development spending in the United Kingdom.

We begin to separately track program expenses beginning at candidate nomination and accumulate all costs

incurred to support each program to date. Through December 31, 2020, we have incurred approximately $13.5 million,
$14.3 million, $11.1 million and $5.3 million of direct expenses for the development of the BT1718, BT5528, BT8009 and
TICA programs, respectively.

General and administrative expenses increased by $14.6 million for the year ended December 31, 2020 as
compared to the year ended December 31, 2019, primarily due to increases of $8.5 million in professional and consulting
fees, including $4.7 million of expense related to the settlement and license agreement with Pepscan entered into in
November 2020 as well as increased legal, human resources, and consulting costs to support operations as a public
company, $2.1 million in share-based compensation expense; $1.9 million in personnel related costs due to increases in
headcount; $1.8 million in other general and administrative costs, including insurance expense to support operations as a
public company; and $0.3 million unfavorable effect of foreign exchange rates during the year ended December 31, 2020
as compared to the year ended December 31, 2019.

Other Income (Expense), net

Other income (expense), net decreased by $4.8 million for the year ended December 31, 2020, compared to the

year ended December 31, 2019. In the year ended December 31, 2020, we recognized $0.7 million of interest income and
$0.5 million in interest expense related to our debt facility entered into on September 30, 2020, whereas in the year ended
December 31, 2019, we recognized $5.4 million of other expense associated with changes in the fair value of the warrant
liability and final re-measurement upon completion of the IPO, offset by $0.8 million of interest income.

Liquidity and Capital Resources

From our inception through December 31, 2020, we have not generated any revenue from product sales and have
incurred significant operating losses and negative cash flows from our operations. We do not expect to generate significant
revenue from sales of any products for several years, if at all.

To date, we have financed our operations primarily with proceeds from the sale of ordinary shares (including in

the form of ADSs) and convertible preferred shares, as well as proceeds received from upfront payments, payments for
research and development services, and development milestone payments from our collaboration agreements with
Genentech, AstraZeneca, Oxurion, Sanofi, DDF, and borrowings pursuant to our debt facility.

Table of Contents

From our inception in 2009 through December 31, 2020, we have received gross proceeds of $243.4 million from

the sale of ordinary shares (including in the form of ADSs) and convertible preferred shares, including the proceeds from
our IPO; $63.1 million of cash payments under our collaboration revenue arrangements including $31.0 million from
Genentech, $10.3 million from AstraZeneca, $4.1 million from Oxurion, $15.0 million from Sanofi, $1.7 million from
DDF; $15.0 of borrowings pursuant to our Loan Agreement with Hercules. In January 2021, we received $2.4 million from
Oxurion due to a milestone achieved for the initiation of a Phase II trial of THR-149 and $3.0 million of proceeds under an
evaluation and option agreement.

Net cash used in operating activities for the year ended December 31, 2020 included our net loss of $51.0 million,

net cash used in our operating assets and liabilities of $25.4 million and non-cash charges of $7.9 million, which included
share-based compensation expense of $6.5 million, depreciation and amortization of $1.3 million, and non-cash interest
related to the Loan Agreement of $0.1 million. Net changes in our operating assets and liabilities for the year ended
December 31, 2020 consisted primarily of an increase in deferred revenue of $24.6 million primarily due to upfront
payments received from collaboration arrangement with Genentech; an increase of $4.8 million in accrued expenses and
other current liabilities, primarily due to accrued external research and development costs; and an increase of $0.5 million
in other long-term liabilities. These were offset by an increase of $2.1 million in accounts receivable and an increase of
$1.8 million in research and development incentives receivable.

Net cash used in operating activities for the year ended December 31, 2019 included our net loss of $30.6 million,

net cash used in our operating assets and liabilities of $7.4 million and non-cash charges of $9.4 million, which included
share-based compensation expense of $3.1 million, depreciation and amortization of $1.0 million, and changes in the fair
value of the warrant liability of $5.4 million. Net changes in our operating assets and liabilities for the year ended
December 31, 2019, consisted primarily of a decrease in accounts receivable of $4.9 million, primarily due to a payment
received from AstraZeneca for its exercise of an option; a decrease in deferred revenue of $9.3 million, primarily due to the
recognition of revenue related to the Sanofi collaboration arrangement; a decrease in accrued expenses and other current
liabilities of $0.9 million; and an increase in prepaid expenses and other assets of $3.1 million, primarily due to prepaid
clinical costs, offset by an increase in accounts payable of $0.2 million and an increase in other long-term liabilities of $1.1
million.

Investing Activities

During the years ended December 31, 2020 and 2019, we used $1.2 million and $1.6 million, respectively, of cash

in investing activities for purchases of property and equipment consisting primarily of laboratory equipment.

Financing Activities

During the year ended December 31, 2020, net cash provided by financing activities was $62.8 million, primarily

consisting of net proceeds from our ATM program of $48.1 million and borrowings of $15.0 million under our Loan
Agreement with Hercules, offset by the payment of debt issuance costs of $0.6 million.

During the year ended December 31, 2019, net cash provided by financing activities was $58.4 million, primarily
consisting of net proceeds of $57.0 million from our IPO, and net proceeds of $1.3 million from our Series B2 convertible
preferred shares issued in January 2019.

Loan Agreement

On September 30, 2020, or the Closing Date, we entered into the Loan Agreement with Hercules as agent, which
provided for aggregate maximum borrowings of up to $40.0 million, consisting of (i) a term loan of $15.0 million, which
was funded on the Closing Date, (ii) subject to customary conditions, an additional term loan of up to $15.0 million
available from the Closing Date through March 15, 2021, and (iii) subject to our achievement of certain performance
milestones and satisfaction of customary conditions and available until March 15, 2022, an additional term loan of $10.0
million. Borrowings under the Loan Agreement, including the $15.0 million term loan issued as of September 30, 2020
bear interest at an annual rate equal to the greater of (i) 8.85% and (ii) the prime rate of interest plus 5.60%. The Loan
Agreement provides for interest-only payments until November 1, 2022, which may be extended to May 1, 2023 upon our
achievement of certain performance milestones, followed by equal monthly payments of principal and interest through
October 1, 2024, or the Maturity Date. We may prepay all or any portion greater than $5.0 million of the outstanding
borrowings, subject to a prepayment premium equal to 2.0% of the principal amount outstanding if the prepayment occurs
during the first year following the Closing Date, 1.5% of the principal amount outstanding if the prepayment occurs during
the second year following the Closing Date and 1.0% thereafter but prior to the Maturity Date. The Loan Agreement also
provides for an end of term charge, payable upon maturity or the repayment of obligations under the Loan Agreement,
equal to 5.0% of the principal amount repaid. In connection with the Loan Agreement, we granted Hercules a security
interest in substantially all of our personal property and other assets, other than our intellectual property. The Loan
Agreement includes a right for the lenders to invest in an amount of up to $2.0 million in the closing of any our financings
after the Closing Date that result in aggregate proceeds to us of at least $10.0 million. In addition, the Loan Agreement
contains customary affirmative and restrictive covenants and representations and warranties, including a covenant against
the occurrence of a change in control (as defined in the Loan Agreement), financial reporting obligations, and certain
limitations on indebtedness, liens (including a negative pledge on intellectual property and other assets), investments,
distributions (including dividends), collateral, investments, transfers, mergers or acquisitions, taxes, corporate changes, and
deposit accounts. The Loan Agreement also includes customary events of default, including payment defaults, breaches of
covenants following any applicable cure period, the occurrence of certain events that could reasonably be expected to have
a “material adverse effect” as set forth in the Loan Agreement, cross acceleration to third-party indebtedness and certain
events relating to bankruptcy or insolvency. Upon the occurrence of an event of default, a default interest rate of an
additional 5.0% may be applied to the outstanding principal balance, and Hercules may declare all outstanding obligations
immediately due and payable and take such other actions as set forth in the Loan Agreement. There are no financial
covenants. If we fail to make payments when due, or breach any operational covenant or have any event of default, this
could have a material adverse effect on our business and financial condition.

Funding Requirements

We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we

advance the preclinical activities and clinical trials of our product candidates and as we:

● continue our development of our product candidates, including conducting future clinical trials for BT1718,

BT5528, and BT8009;

● progress the preclinical and clinical development of BT7480, BT7455, and BT7401;

● seek to identify and develop additional product candidates;

● develop the necessary processes, controls and manufacturing data to seek to obtain marketing approval for

our product candidates and to support manufacturing of product to commercial scale;

● develop, maintain, expand and protect our intellectual property portfolio;

121

Table of Contents

● seek marketing approvals for any of our product candidates that successfully complete clinical trials, if any;

● hire and retain additional personnel, such as non-clinical, clinical, pharmacovigilance, quality assurance,

regulatory affairs, manufacturing, distribution, legal, compliance, medical affairs, finance, commercial and
scientific personnel;

● acquire or in-license other products and technologies;

● expand our infrastructure and facilities to accommodate our growing employee base, including adding

equipment and infrastructure to support our research and development; and

● add operational, financial and management information systems and personnel, including personnel to

support our research and development programs, any future commercialization efforts and our operations as a
public company.

In addition, if we obtain marketing approval for any product candidate that we identify and develop, we expect to 

incur significant commercialization expenses related to product sales, marketing, manufacturing, and distribution to the 
extent that such sales, marketing, and distribution are not the responsibility of our collaboration partners. Even if we are 
able to generate product sales, we may not become profitable. Accordingly, we will need to obtain substantial additional 
funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, 
we would be forced to delay, reduce, or eliminate our research and development programs or future commercialization 
efforts.  

As of December 31, 2020, we had cash of $136.0 million. We expect that our existing cash will enable us to fund

our operating expenses and capital expenditure requirements for at least twelve months from the date of filing of this
Annual Report on Form 10-K. We have based our estimates on assumptions that may prove to be wrong, and we may use
our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated
with the development of product candidates and programs, and because the extent to which we may enter into
collaborations with third parties for development of our product candidates is unknown, we are unable to estimate the
timing and amounts of increased capital outlays and operating expenses associated with completing the research and
development of our product candidates. Our future capital requirements will depend on many factors, including:

● our ability to raise capital in light of the impacts of the ongoing global COVID-19 pandemic on the global 

financial  markets;

● the scope, progress, results, and costs of drug discovery, preclinical development, laboratory testing, and

clinical trials for the product candidates we may develop;

● our ability to enroll clinical trials in a timely manner and to quickly resolve any delays or clinical holds that
may be imposed on our development programs, particularly in light of the ongoing global COVID-19
pandemic;

● the costs associated with our manufacturing process development and evaluation of third-party manufacturers

and suppliers;

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

● the costs of preparing and submitting marketing approvals for any of our product candidates that successfully

complete clinical trials, and the costs of maintaining marketing authorization and related regulatory
compliance for any products for which we obtain marketing approval;

● the costs of preparing, filing, and prosecuting patent applications, maintaining and enforcing our intellectual

property and proprietary rights, and defending intellectual property-related claims;

122

Table of Contents

● the costs of future activities, including product sales, medical affairs, marketing, manufacturing, and

distribution, for any product candidates for which we receive marketing approval;

● the terms of our current and any future license agreements and collaborations; and the extent to which we

acquire or in-license other product candidates, technologies and intellectual property.

● the success of our collaborations with Genentech, AstraZeneca, Oxurion and DDF;

● our ability to establish and maintain additional collaborations on favorable terms, if at all; and

● the costs of operating as a public company.

Until such time, if ever, that we can generate product revenue sufficient to achieve profitability, we expect to 

finance our cash needs through a combination of equity offerings, debt financings, collaborations, monetization 
transactions, government contracts or other strategic transactions. To the extent that we raise additional capital through the 
sale of equity, ownership interests of existing holders of our ADSs and ordinary shares will be diluted, and the terms of 
these securities may include liquidation or other preferences that adversely affect the rights of holders of our ADSs or 
ordinary shares. If we raise additional funds through collaboration agreements, strategic alliances, licensing arrangements, 
monetization transactions, or marketing and distribution arrangements, 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 or grant rights to develop and market products or product candidates that we would otherwise prefer to 
develop and market ourselves. Future debt financing, if available, may involve covenants restricting our operations or our 
ability to incur additional debt. Any debt or equity financing that we raise may contain terms that are not favorable to us or 
our shareholders. The ongoing COVID-19 pandemic continues to evolve and has already resulted in a significant 
disruption of global financial markets.  If the disruption persists and deepens, whether as a result of the pandemic or 
otherwise, we could experience an inability to access additional capital, which could in the future negatively affect our 
operations. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate 
our product development or future commercialization.

(1) Amounts reflect minimum payments due for our office and laboratory space leases. We have one office lease in

Cambridge, U.K. under an operating lease that expires in December 2021. We lease laboratory space in Lexington,
Massachusetts under an operating lease that expires in December 2022.

(2) Amounts in the table reflect the contractually required principal, interest and the final payment under the Loan

Agreement with Hercules as of December 31, 2020

In the ordinary course of business, we enter into various agreements with contract research organizations to
provide clinical trial services, with contract manufacturing organizations to provide clinical trial materials, and with
vendors for preclinical research studies, synthetic chemistry and other services for operating purposes. These payments are
not included in the table of contractual obligations above since the contracts are generally cancelable with advanced written
notice, with a notice period of 90 days or less. From the time of notice until termination, we are contractually

Table of Contents

obligated to make certain minimum payments to the vendors, based on the timing of the notification and the exact terms of
the agreement.

Our arrangements with Cancer Research UK provide for additional future milestone payments upon the
achievement of development, regulatory and commercial milestones, payable in cash and shares, with an aggregate total
value of $111.2 million, as well as royalty payments based on a single digit percentage on net sales of products developed.
In addition, in November 2020, we entered into a settlement and license agreement with Pepscan Systems B.V. regarding
our use of Pepscan’s CLIPS peptide technology, which agreement provides for additional future milestone payments by us
upon the achievement of development, regulatory and commercial milestones, with an aggregate total value of $92.4
million. We have not included future payments under this agreement in the table of contractual obligations above since
these obligations are contingent upon future events. As of December 31, 2020, we were unable to estimate the timing or
likelihood of achieving these milestones.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our

consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of our
consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect the
reported amounts of assets and liabilities, costs and expenses and the disclosure of contingent assets and liabilities in our
consolidated financial statements. We base our estimates on historical experience, known trends and events and various
other factors that we believe are reasonable under the circumstances, the results of which form the basis for making
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate
our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different
assumptions or conditions.

While our significant accounting policies are described in greater detail in Note 2 to our consolidated financial

statements appearing elsewhere in the Annual Report on Form 10-K, we believe that the following accounting policies are
those most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Collaboration Revenues

Our revenues are generated primarily through collaborative arrangements and license agreements with

pharmaceutical companies. The terms of these arrangements may include (i) performing research and development services
using our bicyclic peptide screening platform with the goal of identifying compounds for further development and
commercialization, (ii) options to obtain additional research and development services or licenses for additional targets, or
to optimize product candidates, upon the payment of option fees, or (iii) the transfer of intellectual property rights
(licenses).

The terms of these arrangements typically include payment to us of one or more of the following: non-refundable

upfront license fees; payments for research and development services; fees upon the exercise of options to obtain additional
services or licenses; payments based upon the achievement of defined collaboration objectives; future regulatory and sales-
based milestone payments; and royalties on net sales of future products.

We recognize revenue in accordance with ASU 2014-09, Revenue from Contracts with Customers (Topic 606) or
ASC 606, and all subsequent amendments. This standard applies to all contracts with customers, except for contracts that
are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments.

124

Table of Contents

Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in

an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services.

To determine revenue recognition for arrangements that we determine are within the scope of ASC 606, we
perform the following five steps: (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, we satisfy the performance obligations. We only apply the five-step model
to contracts when it is probable that we will collect substantially all of the consideration we are entitled to in exchange for
the goods or services it transfers to the customer. As part of the accounting for these arrangements, we must make
significant judgments, including identifying performance obligations in the contract, estimating the amount of variable
consideration to include in the transaction price and allocating the transaction price to each performance obligation.

Once a contract is determined to be within the scope of ASC 606, we assess the goods or services promised within

the contract and determine those that are performance obligations. Arrangements that include rights to additional goods or
services that are exercisable at a customer’s discretion are generally considered options. We assess if these options provide
a material right to the customer and if so, they are considered performance obligations.

Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the

customer. The promised goods or services in our contracts with customers primarily consist of license rights to our
intellectual property for research and development, research and development services, and options to acquire additional
research and development services or options to obtain additional licenses, such as a commercialization license for a
potential product candidate. Promised goods or services are considered distinct when: (i) the customer can benefit from the
good or service on its own or together with other readily available resources, and (ii) the promised good or service is
separately identifiable from other promises in the contract. In assessing whether promised goods or services are distinct, we
consider factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to
develop the intellectual property on their own and whether the required expertise is readily available. In addition, we
consider whether the collaboration partner can benefit from a promise for its intended purpose without the receipt of the
remaining promises, whether the value of the promise is dependent on the unsatisfied promises, whether there are other
vendors that could provide the remaining promises, and whether it is separately identifiable from the remaining promises.

We estimate the transaction price based on the amount of consideration we expect to receive for transferring the

promised goods or services in the contract. The consideration may include both fixed consideration and variable
consideration. At the inception of each arrangement that includes variable consideration, we evaluate the amount of the
potential payments and the likelihood that the payments will be received. We utilize either the most likely amount method
or expected value method to estimate variable consideration to include in the transaction price based on which method
better predicts the amount of consideration expected to be received. The amount included in the transaction price is
constrained to the amount for which it is probable that a significant reversal of cumulative revenue recognized will not
occur. At the end of each subsequent reporting period, we re-evaluate the estimated variable consideration included in the
transaction price and any related constraint, and if necessary, adjust our estimate of the overall transaction price. Any such
adjustments are recorded on a cumulative catch-up basis in the period of adjustment.

After determining the transaction price, we allocate it to the identified performance obligations based on the
estimated standalone selling prices. We must develop assumptions that require judgment to determine the standalone
selling price for each performance obligation identified in the contract. We utilize key assumptions to determine the
standalone selling price, which may include other comparable transactions, pricing considered in negotiating the
transaction, probabilities of technical and regulatory success and the estimated costs. Certain variable consideration is
allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration
relate to the satisfaction of the performance obligation and the resulting amounts allocated to each performance obligation
are consistent with the amounts we would expect to receive for each performance obligation.

125

Table of Contents

We then recognize as revenue in the amount of the transaction price that is allocated to the respective performance

obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time based on
the use of an output or input method.

Licenses of Intellectual Property:  If a license to our intellectual property is determined to be distinct from the 

other promises or performance obligations identified in the arrangement, we recognize revenue from non-refundable, 
upfront fees allocated to the license when the license is transferred to the customer and the customer is able to use and 
benefit from the license. For licenses that are combined with other promises, such as research and development services 
and a research license, we utilize 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. We evaluate the measure of progress each reporting 
period and, if necessary, adjusts the measure of performance and related revenue recognition. The measure of progress, and 
thereby periods over which revenue should be recognized, are subject to estimates by management and may change over 
the course of the research and development and licensing agreement.

Research and Development Services:  The promises under our collaboration agreements may include research and 

development services to be performed by us on behalf of the partner. Payments or reimbursements resulting from our 
research and development efforts are recognized as the services are performed and presented on a gross basis because we 
are the principal for such efforts.

Customer Options:  We evaluate customer options to obtain additional items (i.e. additional license rights) for 
material rights, or options to acquire additional goods or services for free or at a discount. Optional future services that 
reflect their standalone selling prices do not provide the customer with a material right and, therefore, are not considered 
performance obligations and are accounted for as separate contracts. If optional future services reflect a significant or 
incremental discount, they are material rights, and are accounted for as performance obligations. We allocate the 
transaction price to material rights based on the relative standalone selling price, which is determined based on the 
identified discount and the probability that the customer will exercise the option. Amounts allocated to a material right are 
not recognized as revenue until, at the earliest, the option is exercised or expires.

Milestone Payments:  Our collaboration agreements may include development and regulatory milestones. We 

evaluate whether the milestones are considered probable of being reached and estimate the amounts to be included in the 
transaction price using the most likely amount method. We evaluate factors such as the scientific, clinical, regulatory, 
commercial, and other risks that must be overcome to achieve the particular milestone in making this assessment. If it is 
probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction 
price. Milestone payments that are not within our control or the licensee’s control, such as marketing approvals, are not 
considered probable of being achieved until those approvals are received. At the end of each reporting period, we re-
evaluate the probability of achievement of such milestones and any related constraint, and if necessary, adjusts the estimate 
of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect 
collaboration revenue and net loss in the period of adjustment.

Royalties:  For sales-based royalties, including milestone payments based on the level of sales, we determine 

whether the sole or predominant item to which the royalties relate is a license. When the license is the sole or predominant 
item to which the sales-based royalty relates, we recognize 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, we have not recognized any sales-based royalty revenue resulting from our collaboration agreements.

We receive payments from customers based on billing schedules established in each contract. Up-front payments

and fees are recorded as deferred revenue upon receipt or when due until we perform our obligations under these
arrangements. Amounts are recorded as accounts receivable when our right to consideration is unconditional, such as when
we have a contractual right to payment per the terms of the contract.

126

 Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued
research and development expenses. This process involves reviewing open contracts and purchase orders, communicating
with our personnel to identify services that have been performed on our behalf and estimating the level of service
performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of
actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-determined
schedule or when contractual milestones are met; however, some require advanced payments. We make estimates of our
accrued expenses as of each balance sheet date in the consolidated financial statements based on facts and circumstances
known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:

● vendors in connection with performing research activities on our behalf and conducting preclinical studies

and clinical trials on our behalf;

● CMOs in connection with the production of preclinical and clinical trial materials;

● CROs, investigative sites or other service providers in connection with clinical trials;

● vendors in connection with preclinical and clinical development activities; and

● vendors related to product manufacturing and development and distribution of preclinical and clinical

supplies.

We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and

efforts expended pursuant to quotes and contracts with multiple CMOs, research institutions and vendors that supply,
conduct and manage preclinical studies and clinical trials on our behalf. The financial terms of these agreements are subject
to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which
payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. In
accruing service fees, we estimate the time period over which services will be performed and the level of effort to be
expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate,
we adjust the accrual or the amount of prepaid expenses accordingly. Although we do not expect our estimates to be
materially different from amounts actually incurred, our understanding of the status and timing of services performed
relative to the actual status and timing of services performed may vary and actual results could differ from our estimates.
As of December 31, 2020, there have not been any material adjustments to our prior estimates of accrued research and
development expenses.

Share-Based Compensation

We measure share-based awards granted to employees and directors based on their fair value on the date of the

grant and recognize compensation expense for those awards over the requisite service period, which is generally the
vesting period of the respective award. We record the expense for awards with only service-based vesting conditions using
the straight-line method and account for forfeitures as they occur.

We have granted awards that include both a service condition, that vests over time, and a performance condition,

that will accelerate vesting upon the achievement of a specified collaboration revenue threshold. For equity awards that
contain both performance and service conditions, we recognize share-based compensation expense using an accelerated
attribution model over the requisite service period when the achievement of a performance-based milestone is probable
based on the relative satisfaction of the performance condition as of the reporting date.

The fair value of each share option is estimated using the Black-Scholes option-pricing model, which requires

inputs based on certain subjective assumptions, including the fair value of ordinary shares, the expected share price
volatility, the expected term of the award, the risk-free interest rate, and expected dividends. The assumptions used in

127

Table of Contents

computing the fair value of stock option awards reflect our best estimates but involve uncertainties related to market and
other conditions, many of which are outside of our control. Changes in any of these assumptions may materially affect the
fair value of share-based awards granted and the amount of share-based compensation recognized in future periods.

Research and Development Incentives and Receivable

We receive reimbursements of certain research and development expenditures, through our subsidiaries in the
United Kingdom, as part of a United Kingdom government’s research and development tax reliefs program. Under the
program, a percentage of qualifying research and development expenses incurred by our subsidiaries in the United
Kingdom are reimbursed up to 14.5% of the surrenderable losses. We assess our research and development activities and
expenditures to determine which activities and expenditures are likely to be eligible under the research and development
incentive program described above. At each period end, we estimate the reimbursement available to the Company based on
available information at the time.

We recognize income from the research and development incentives when the relevant expenditure has been

incurred, the associated conditions have been satisfied and there is reasonable assurance that the reimbursement will be
received. We record these research and development incentives as a reduction to research and development expenses in the
statements of operations and comprehensive loss, as the research and development tax credits are not dependent on us
generating future taxable income, our ongoing tax status, or tax position. The refund is denominated in pounds sterling and,
therefore, the receivable is remeasured into U.S. dollars as of each reporting date. The research and development incentives
receivable represents an amount due in connection with the above program.

Emerging Growth Company and Smaller Reporting Company Status

We are an “emerging growth company,” or EGC, as defined in the Jumpstart Our Business Startups Act of 2012,

or the JOBS Act, We will remain an EGC until the earlier of (1) the last day of the fiscal year following the fifth
anniversary of the completion of our initial public offering (December 31, 2024), (2) the last day of the fiscal year in which
we have total annual gross revenue of at least $1.07 billion, (3) the last day of the fiscal year in which we are deemed to be
a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act of 1934, as amended, or the Exchange Act,
which would occur if the market value of our ordinary shares held by non-affiliates exceeded $700.0 million as of the last
business day of the second fiscal quarter of such fiscal year or (4) the date on which we have issued more than $1.0 billion
in non-convertible debt securities during the prior three-year period. The JOBS Act permits an EGC to take advantage of
an extended transition period to comply with new or revised accounting standards applicable to public companies until
those standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision
and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public
companies that are not emerging growth companies.

In addition, we intend to rely on the other exemptions and reduced reporting requirements available to EGCs 
provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, we are not required to, among other 
things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to 
Section 404(b), (ii) provide all of the compensation disclosure that may be required of non-emerging growth public 
companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that 
has or may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a 
supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor 
discussion and analysis), and (iv) disclose certain executive compensation-related items such as the correlation between 
executive compensation and performance and comparisons of the chief executive officer’s compensation to median 
employee compensation. These exemptions will apply until the earlier to occur of (i) the end of the year in which the fifth 
anniversary of our IPO occurs, or December 31, 2024, or (b) we no longer meet the requirements of being an emerging 
growth company.  

We are also a smaller reporting company as defined in the Exchange Act.  We may continue to be a smaller 

reporting company even after we are no longer an emerging growth company. We may, and intend to, take advantage of 
certain of the scaled disclosures available to smaller reporting companies for so long as we are a smaller reporting 
company.  We may be a smaller reporting company in any year in which (i) the market value of our voting and non-

128

Table of Contents

voting ordinary shares held by non-affiliates is less than $250.0 million measured on the last business day of our second 
fiscal quarter or (ii) (a) our annual revenue is less than $100.0 million during the most recently completed fiscal year and 
(b) the market value of our voting and non-voting ordinary shares held by non-affiliates is less than $700.0 million 
measured on the last business day of our second fiscal quarter.

Off-balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements

and do not have any holdings in variable interest entities, as defined in the rules and regulations of the SEC.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Interest Rate Sensitivity

As of December 31, 2020, we had cash of $136.0 million. Our exposure to interest rate sensitivity is impacted by
changes in the underlying U.K. and U.S. bank interest rates. Our surplus cash has been invested in interest-bearing savings
accounts. We have not entered into investments for trading or speculative purposes. Due to the conservative nature of our
investment portfolio, which is predicated on capital preservation of investments with short-term maturities, we do not
believe an immediate one percentage point change in interest rates would have a material effect on the fair market value of
our portfolio, and therefore we do not expect our operating results or cash flows to be significantly affected by changes in
market interest rates.

We are subject to interest rate risk in connection with our borrowings under our credit facility with Hercules,
which were $15.0 million as of December 31, 2020. Our outstanding indebtedness with Hercules bears interest at the
greater of 8.85%, or 5.60% plus the Wall Street Journal prime rate. As of December 31, 2020, our outstanding indebtedness
with Hercules bears interest at 8.85%. If the prime rate increases to over 3.25%, the interest on our loan with Hercules will
increase. We currently do not engage in any interest rate hedging activity, and we have no intention to do so in the
foreseeable future. Based on the current interest rate of the term loan and the scheduled payments thereunder, we do not
believe a 1.0% increase in interest rates would have a material impact on our financial condition or results of operations.

Foreign Currency Exchange Risk

The functional currency is the currency of the primary economic environment in which an entity’s operations are
conducted. The functional currency of Bicycle Therapeutics plc and Bicycle Therapeutics Inc. is the United States dollar.
The functional currency of its wholly owned non-U.S. subsidiaries, BicycleTx Limited and BicycleRD Limited, is the
British Pound Sterling and the consolidated financial statements are presented in United States Dollars, USD. The
functional currency of the Company’s subsidiaries is the same as the local currency.

Monetary assets and liabilities denominated in currencies other than the functional currency are remeasured into

the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities
denominated in foreign currencies are remeasured into the functional currency at the exchange rates prevailing at the date
of the transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of
net loss for the respective periods. Adjustments that arise from exchange rate changes on transactions denominated in a
currency other than the local currency are included in general and administrative expense in the consolidated statements of
operations and comprehensive loss as incurred. We recorded foreign exchange gains of $0.6 million, $0.9 million and
$0.3 million for the years ended December 31, 2020, 2019 and 2018, respectively.

For financial reporting purposes, our consolidated financial statements have been translated into U.S. dollars. We
translate the assets and liabilities of BicycleTx Limited and BicycleRD Limited into USD at the exchange rate in effect on
the balance sheet date. Revenues and expenses are translated at the average exchange rate in effect during the period and
shareholders’ equity (deficit) amounts are translated based on historical exchange rates as of the date of each transaction.
Translation adjustments are not included in determining net loss but are included in our foreign exchange

129

Table of Contents

adjustment included in the consolidated statements of convertible preferred shares and shareholders’ equity (deficit) as a
component of accumulated other comprehensive income (loss).

We do not currently engage in currency hedging activities in order to reduce our currency exposure, but we may

begin to do so in the future.

ITEM 9A.     CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures.

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the

Exchange Act, that are designed to ensure that information required to be disclosed in the reports that we file or submit
under the Exchange Act is (1) recorded, processed, summarized and reported, within the time periods specified in the
SEC’s rules and forms and (2) accumulated and communicated to our management, including our principal executive
officer and principal financial officer, 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.

Our management, with the participation of our principal executive officer and our principal financial officer,

evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2020. Based on the evaluation of
our disclosure controls and procedures as of December 31, 2020, our Chief Executive Officer and Chief Financial Officer
concluded that, as of such date, our disclosure controls and procedures were effective.

Management’s Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial
reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act. Because of its
inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 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 policies or procedures may deteriorate. Our internal control
over financial reporting is a process designed under the supervision of our principal executive officer and principal
financial officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our
financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

Our management conducted an assessment of our internal control over financial reporting based on the framework

established in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-
Integrated Framework (2013). Based on the assessment, management concluded that our internal control over financial
reporting was effective as of December 31, 2020.

ITEM 9B.     OTHER INFORMATION.

First Amendment to Loan and Security Agreement

On March 10, 2021, or the Amendment Closing Date, we and our subsidiaries entered into the First Amendment 

to the Loan and Security Agreement, or the First Amendment to LSA, with Hercules, in its capacity as administrative agent 
and collateral agent, and the Lenders named in the First Amendment to LSA.  The First Amendment to LSA amended 
certain terms of our debt facility with Hercules. 

Pursuant to the First Amendment to LSA, payments on our borrowings under our debt facility with Hercules will 
be interest-only until the first payment is due on August 1, 2023, which date was extended from November 1, 2022.  If we 
achieve certain performance milestones, the interest-only period will be extended, with the first principal payment due on 
February 1, 2024, which date was extended from May 1, 2023.  

On the Amendment Closing Date and pursuant to the terms of the First Amendment to LSA, we borrowed the 

additional term loan of $15.0 million that had been available from September 30, 2020 to March 15, 2021.  

The foregoing summary description of the First Amendment to LSA does not purport to be complete and is

qualified in its entirety by reference to the full text of the First Amendment to LSA, which is attached as Exhibit 10.28 to

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Bicycle Therapeutics plc

Opinion on the Financial Statements

We have audited the accompanying Consolidated Balance Sheets of Bicycle Therapeutics plc and its subsidiaries (the 
“Company”) as of December 31, 2020 and 2019, and the related Consolidated Statements of Operations and 
Comprehensive Loss, of Convertible Preferred Shares and Shareholders’ Equity (Deficit) and of Cash Flows for each of the 
three years in the period ended December 31, 2020, including the related notes (collectively referred to as 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, 2020 and 2019, and the results of its operations and its cash flows 
for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally 
accepted in the United States of America.  

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to
express an opinion on the Company’s 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 of these consolidated financial statements 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.

/s/ PricewaterhouseCoopers LLP

Cambridge, United Kingdom
March 11, 2021

We have served as the Company's or its predecessor’s auditor since 2010, which includes periods before the Company
become subject to SEC reporting requirements.

Bicycle Therapeutics plc

Notes to Consolidated Financial Statements

1. Nature of the business and basis of presentation

Bicycle Therapeutics plc (collectively with its subsidiaries, the “Company”) is a clinical-stage biopharmaceutical

company developing a novel class of medicines, which the Company refers to as Bicycles, for diseases that are underserved
by existing therapeutics. Bicycles are a unique therapeutic modality combining the pharmacology usually associated with a
biologic with the manufacturing and pharmacokinetic properties of a small molecule. The Company’s initial internal
programs are focused on oncology indications with high unmet medical need. The Company’s lead product candidate,
BT1718, is a Bicycle Toxin Conjugate (“BTC”) that is being developed to target tumors that express Membrane Type 1
matrix metalloproteinase. BT1718 is being investigated for safety, tolerability and efficacy in an ongoing Phase I/IIa
clinical trial in collaboration with, and fully funded by, the Centre for Drug Development of Cancer Research UK. The
Company is also evaluating BT5528, a second-generation BTC targeting Ephrin type-A receptor 2 (“EphA2”), in a
Company-sponsored Phase I/II clinical trial as a monotherapy and in combination with nivolumab, and BT8009, a second-
generation BTC targeting Nectin-4, in a Company-sponsored Phase I/II clinical trial. The Company’s discovery pipeline in
oncology includes Bicycle-based systemic immune cell agonists and Bicycle tumor-targeted immune cell agonists (TICAs).
Beyond the Company’s wholly-owned oncology portfolio, the Company is collaborating with biopharmaceutical
companies and organizations in immuno-oncology, anti-infective, cardiovascular, ophthalmology, dementia and respiratory
indications.

The accompanying consolidated financial statements include the accounts of Bicycle Therapeutics plc and its

wholly owned subsidiaries, BicycleTx Limited, BicycleRD Limited and Bicycle Therapeutics Inc. All intercompany
balances and transactions have been eliminated on consolidation.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles

generally accepted in the United States of America (“GAAP”).

Liquidity

On May 28, 2019, the Company completed its initial public offering (the “IPO”), pursuant to which it issued and

sold 4,333,333 American Depositary Shares (“ADSs”), representing the same number of ordinary shares at a public
offering price of $14.00 per ADS. In addition, in June 2019, the Company issued and sold an additional 304,333 ADSs,
pursuant to the partial exercise of the underwriters’ option to purchase additional ADSs. The aggregate net proceeds
received by the Company from the IPO were $56.4 million, after deducting underwriting discounts and commissions of
$4.5 million and offering expenses of $4.0 million.

On June 5, 2020, the Company entered into a Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald &
Co. and Oppenheimer & Co. Inc. (the “Sales Agents”) with respect to an at-the-market offering program (“ATM”) pursuant
to which the Company may offer and sell through the Sales Agents, from time to time at the Company’s sole discretion,
ADSs, each ADS representing one ordinary share. As of December 31, 2020, the Company had issued and sold 2,928,813
ADSs, representing the same number of ordinary shares for gross proceeds of $50.0 million, resulting in net proceeds of
$48.1 million after deducting sales commissions and offering expenses of $1.9 million.

On September 30, 2020, Bicycle Therapeutics plc and certain of its subsidiaries (together with Bicycle

Therapeutics plc, the “Borrowers”) entered into a loan and security agreement (the “Loan Agreement”) with Hercules
Capital, Inc. (“Hercules”) as agent, which provided for maximum borrowings of up to $40.0 million in aggregate principal
amount, consisting of (i) a term loan of $15.0 million, which was funded on September 30, 2020, (ii) subject to satisfaction
of customary conditions, an additional term loan of up to $15.0 million available from September 30, 2020 through March
15, 2021, and (iii) subject to the achievement of certain performance milestones and satisfaction of customary conditions,
an additional term loan of $10.0 million available until March 15, 2022.

Table of Contents

The Company is subject to risks common to companies in the biotechnology industry and in light of the ongoing

COVID-19 pandemic, including but not limited to, risks of delays in initiating or continuing research programs and clinical
trials, risks of failure of preclinical studies and clinical trials, the need to obtain marketing approval for any drug product
candidate that it may identify and develop, the need to successfully commercialize and gain market acceptance of its
product candidates, dependence on key personnel and collaboration partners, protection of proprietary technology,
compliance with government regulations, development by competitors of technological innovations, and the ability to
secure additional capital to fund operations. Product candidates currently under development will require significant
additional research and development efforts, including preclinical and clinical testing and regulatory approval prior to
commercialization. Even if the Company’s research and development efforts are successful, it is uncertain when, if ever,
the Company will realize significant revenue from product sales.

The accompanying consolidated financial statements have been prepared on the basis of continuity of operations,
realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. Since inception,
the Company has devoted substantially all of its efforts to business planning, research and development, recruiting
management and technical staff, and raising capital. The Company has funded its operations with proceeds from the sale of
its ordinary shares and ADSs, including in its IPO completed in May 2019 and pursuant to its ATM program, convertible
preferred shares (Note 7), and proceeds received from its collaboration arrangements (Note 11), and proceeds from the
Loan Agreement with Hercules (Note 6). The Company has incurred recurring losses since inception, including net losses
of $51.0 million for the year ended December 31, 2020, $30.6 million for the year ended December 31, 2019 and
$21.8 million for the year ended December 31, 2018. As of December 31, 2020, the Company had an accumulated deficit
of $151.6 million. The Company expects to continue to generate operating losses in the foreseeable future. As of the
issuance date of the annual consolidated financial statements for the year ended December 31, 2020, the Company expects
that its cash will be sufficient to fund its operating expenses and capital expenditure requirements through at least
twelve months from the issuance date of the annual consolidated financial statements.

The Company expects its expenses to increase substantially in connection with ongoing activities, particularly as
the Company advances its preclinical activities and clinical trials for its product candidates in development. Accordingly,
the Company will need to obtain additional funding in connection with continuing operations. If the Company is unable to
raise capital when needed, or on attractive terms, it could be forced to delay, reduce or eliminate its research or drug
development programs or any future commercialization efforts. Although management continues to pursue these plans,
there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the
Company to fund continuing operations, if at all.

2. Summary of Significant Accounting Policies

Use of estimates

The preparation of consolidated financial statements in conformity with 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, but are not
limited to, the accrual for research and development expenses, revenue recognition, the fair value of ordinary shares and
the valuation of the warrant liability prior to the Company’s IPO, share-based compensation expense, and income taxes.
The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors
that it believes to be reasonable under the circumstances. Estimates are periodically reviewed in light of reasonable changes
in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known.
Actual results could differ from those estimates or assumptions.

Foreign currency and currency translation

The functional currency is the currency of the primary economic environment in which an entity’s operations are

conducted. On June 1, 2019, Bicycle Therapeutics plc adopted the U.S. dollar as its functional currency. Bicycle
Therapeutics plc is a holding company that has no operating activities and its primary functions are to serve as a

F-8

Table of Contents

financing vehicle to fund the operations of the Company’s operating entities, to serve as the listing company needed to
access U.S. capital markets, and to hold investments. Therefore, its financing source is the primary indicator of its cash
flows and its functional currency. The change in functional currency from the British Pound Sterling is due to a change in
the source of Bicycle Therapeutics plc’s financing and cash flows, which following the completion of the IPO is now
primarily the U.S. Dollar (“USD”). Historically its financing had been in British Pound Sterling.

The functional currency of Bicycle Therapeutics plc’s wholly owned non-U.S. subsidiaries, BicycleTx Limited

and BicycleRD Limited, is the British Pound Sterling and the functional currency of its U.S. subsidiary, Bicycle
Therapeutics Inc. is the USD. The functional currency of the Company’s subsidiaries is the same as the local currency.

Monetary assets and liabilities denominated in currencies other than the functional currency are remeasured into

the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities
denominated in foreign currencies are remeasured into the functional currency at the exchange rates prevailing at the date
of the transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of
net loss for the respective periods. Adjustments that arise from exchange rate changes on transactions denominated in a
currency other than the local currency are included in general and administrative expense in the consolidated statements of
operations and comprehensive loss as incurred. The Company recorded foreign exchange gains of $0.6 million,
$0.9 million and $0.3 million for the years ended December 31, 2020, 2019 and 2018, respectively.

The Company translates the assets and liabilities of BicycleTx Limited and BicycleRD Limited into USD at the

exchange rate in effect on the balance sheet date. Revenues and expenses are translated at the average exchange rate in
effect during the period. Unrealized translation gains and losses are recorded as a cumulative translation adjustment, which
is included in the consolidated statements of convertible preferred shares and shareholders’ equity (deficit) as a component
of accumulated other comprehensive loss.

Concentrations of credit risk and of significant suppliers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of

cash and accounts receivable. The Company deposits its cash in financial institutions in amounts that may exceed federally
insured limits and has not experienced any losses on such accounts. The Company does not believe it is exposed to any
unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

Accounts receivable primarily consist of amounts due under the collaboration agreements between BicycleTx

Limited and AstraZeneca AB (“AstraZeneca”), between BicycleRD Limited and Oxurion NV (formerly ThromboGenics
NV) (“Oxurion”), and pursuant to an evaluation and option agreement with another third party (the “Evaluation and Option
Agreement”) (Note 11), for which the Company does not obtain collateral. As of December 31, 2020, the Company’s
revenue to date has primarily been generated from the collaboration agreements with Genentech, Inc. (“Genentech”),
AstraZeneca, Sanofi (formerly Bioverativ), the Dementia Discovery Fund (“DDF”) and Oxurion.

The Company relies, and expects to continue to rely, on a small number of vendors to manufacture supplies and
raw materials for its development programs. These programs could be adversely affected by a significant interruption in
these manufacturing services or the availability of raw materials.

Cash and cash equivalents

The Company considers all highly liquid investments with original maturities of three months or less at date of

purchase to be cash equivalents. The Company had no cash equivalents at December 31, 2020 and 2019.

Accounts receivable

The Company makes judgments as to its ability to collect outstanding receivables and provides an allowance for

receivables when collection becomes doubtful. Provisions are made based upon a specific review of all significant

F-9

Table of Contents

outstanding invoices and the overall quality and age of those invoices. To date, the Company has not had any write-offs of
bad debt, and the Company did not have an allowance for doubtful accounts as of December 31, 2020 and 2019.

Deferred offering costs

The Company capitalizes certain legal, professional accounting and other third-party fees that are directly

associated with in-process equity financings as deferred offering costs until such financings are consummated. After
consummation of the equity financing, these costs are recorded in shareholders’ equity (deficit) as a reduction of proceeds
generated as a result of the offering. Should an in-process equity financing be abandoned, the deferred offering costs will
be expensed immediately as a charge to operating expenses in the consolidated statements of operations and
comprehensive loss.

Property and equipment

Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and

amortization expense is recognized using the straight-line method over the estimated useful lives of the respective assets as
follows:

Laboratory equipment
Leasehold improvements
Computer equipment
Furniture and office equipment

Estimated Useful Life

  3 to 5 years
  Lesser of lease term or useful life
  3 years
  5 years

Costs for capital assets not yet placed into service are capitalized as construction-in-progress and depreciated in
accordance with the above guidelines once placed into service. Upon retirement or sale, the cost of assets disposed of and
the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in loss from
operations. As of December 31, 2020 and 2019, there have been no significant asset retirements to date. Expenditures for
repairs and maintenance are charged to expense as incurred.

Impairment of long-lived assets

Long-lived assets to be held and used are tested for recoverability whenever events or changes in business

circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company
considers in deciding when to perform an impairment review include significant underperformance of the business in
relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the
use of the assets. If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company
compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived
asset group to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows
expected to result from the use of an asset group are less than its carrying amount. The impairment loss would be based on
the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash flows.
To date, the Company has not recorded any impairment losses on long-lived assets.

Fair value measurements

Certain assets and liabilities of the Company are carried at fair value under GAAP. Fair value is defined as the

exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most
advantageous market for the asset or liability in an orderly transaction between market participants on the measurement
date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of
unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the
following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered
unobservable:

● Level 1 — Quoted prices in active markets for identical assets or liabilities.

F-10

    
Table of Contents

● Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for
similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or
liabilities, or other inputs that are observable or can be corroborated by observable market data.

● Level 3 — Unobservable inputs that are supported by little or no market activity that are significant to
determining the fair value of the assets or liabilities, including pricing models, discounted cash flow
methodologies and similar techniques.

Prior to the IPO, the Company’s warrant liability was carried at fair value, determined according to the fair value

hierarchy described above (Note 3). The carrying values of accounts receivable, research and development incentives
receivable, other current assets, accounts payable and accrued expenses and other current liabilities approximate their fair
values due to the short-term nature of these assets and liabilities. At December 31, 2020, the carrying value of the long-
term debt approximates its fair value, which was determined using unobservable Level 3 inputs, including quoted interest
rates from a lender for borrowings with similar terms.

Warrant liability

Prior to the IPO, the Company classified warrants to subscribe for Series A convertible preferred shares (“Series

A Preferred Shares”) and Series B1 convertible preferred shares (“Series B1 Preferred Shares”) (Note 7) as a liability on its
consolidated balance sheets as these warrants to subscribe for Series A Preferred Shares and Series B1 Preferred Shares
were free-standing financial instruments that might have required the Company to transfer assets upon exercise. The
warrant liability was initially recorded at fair value upon the date of the warrants’ issuance and was subsequently
remeasured to fair value at each reporting date. Changes in the fair value of the warrant liability were recognized as a
component of other expense, net in the consolidated statements of operations and comprehensive loss. Upon the closing of
the IPO, warrants to subscribe for Series A Preferred Shares and Series B1 Preferred Shares that were not exercised or
expired in conjunction with the IPO automatically became warrants to subscribe for ordinary shares, and meet the criteria
to be classified as shareholders’ equity (deficit). As such, following the final remeasurement on May 28, 2019, the
Company reclassified the carrying value of the warrant liability to additional paid-in-capital in the consolidated balance
sheet.

Segment and geographic information

Operating segments are defined as components of a business for which separate discrete financial information is

available for evaluation by the chief operating decision maker in deciding how to allocate resources and assess
performance. The Company and its chief operating decision maker, the Company’s Chief Executive Officer, view the
Company’s operations and manages its business as a single operating segment, which is developing a unique class of
chemically synthesized medicines based on its proprietary constrained peptides.

The Company operates in two geographic regions: the United Kingdom and the United States.

Leases

The Company adopted ASC Topic 842, Leases (ASC 842), using a modified retrospective approach, as of January
1, 2019, with no restatement of prior periods or cumulative adjustment to retained earnings. The Company determines if an
arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other
current liabilities, and operating lease liabilities in the Company’s consolidated balance sheet. The Company has not
entered into any financing leases.

ROU assets represent the Company’s right to use and control an underlying asset for the lease term and lease

liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and liabilities are
recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s
leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available
at commencement date in determining the present value of lease payments. The ROU asset also includes lease payments
made before the lease commencement date and excludes any lease incentives. The Company’s

F-11

Table of Contents

lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will
exercise that option.

The components of a lease shall be split into three categories, if applicable: lease components (e.g., land, building,

etc.), non-lease components (e.g., common area maintenance, maintenance, consumables, etc.), and non-components
(e.g., property taxes, insurance, etc.). The fixed and in-substance fixed contract consideration (including any related to non-
components) must then be allocated based on fair values to the lease components and non-lease components. The
Company’s facilities operating leases may have lease and non-lease components to which the Company has elected to
apply a practical expedient to account for each lease component and related non-lease component as one single component.
The lease component results in a right-of-use asset being recorded on the balance sheet. Lease expense for lease payments
is recognized on a straight-line basis over the lease term.

Revenue recognition

The Company’s revenues are generated primarily through collaborative arrangements and license agreements with
pharmaceutical companies. The terms of these arrangements may include (i) performing research and development services
using the Company’s bicyclic peptide screening platform with the goal of identifying compounds for further development
and commercialization, (ii) options to obtain additional research and development services or licenses for additional
targets, or to optimize product candidates, upon the payment of option fees, or (iii) the transfer of intellectual property
rights (licenses).

The terms of these arrangements typically include payment to the Company of one or more of the following: non-

refundable, upfront license fees; payments for research and development services; fees upon the exercise of options to
obtain additional services or licenses; payments based upon the achievement of defined collaboration objectives; future
regulatory and sales-based milestone payments; and royalties on net sales of future products.

The Company recognizes revenue in accordance with ASU 2014-09, Revenue from Contracts with Customers

(Topic 606) (“ASC 606”) and all subsequent amendments. This standard applies to all contracts with customers, except for
contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements 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 which the entity expects to receive in exchange for those goods or services.

To determine revenue recognition for arrangements that the Company determines are within the scope of

ASC 606, it performs the following five steps: (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 Company satisfies the performance obligations. The
Company only applies the five-step model to contracts when it is probable that the entity will collect substantially all of the
consideration it is entitled to in exchange for the goods or services it transfers to the customer. As part of the accounting for
these arrangements, the Company must make significant judgments, including identifying performance obligations in the
contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction
price to each performance obligation.

Once a contract is determined to be within the scope of ASC 606, the Company assesses the goods or services
promised within the contract and determines those that are performance obligations. Arrangements that include rights to
additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company
assesses if these options provide a material right to the customer and if so, they are considered performance obligations.

Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the

customer. The promised goods or services in the Company’s contracts with customers primarily consist of license rights to
the Company’s intellectual property for research and development, research and development services, options to acquire
additional research and development services, and options to obtain additional licenses, such as a

F-12

Table of Contents

commercialization license for a potential product candidate. Promised goods or services are considered distinct when:
(i) the customer can benefit from the good or service on its own or together with other readily available resources, and
(ii) the promised good or service is separately identifiable from other promises in the contract. In assessing whether
promised goods or services are distinct, the Company considers factors such as the stage of development of the underlying
intellectual property, the capabilities of the customer to develop the intellectual property on their own and whether the
required expertise is readily available. In addition, the Company considers whether the collaboration partner can benefit
from a promise for its intended purpose without the receipt of the remaining promises, whether the value of the promise is
dependent on the unsatisfied promises, whether there are other vendors that could provide the remaining promises, and
whether it is separately identifiable from the remaining promises.

The Company estimates the transaction price based on the amount of consideration the Company expects to

receive for transferring the promised goods or services in the contract. The consideration may include both fixed
consideration and variable consideration. At the inception of each arrangement that includes variable consideration, the
Company evaluates the amount of the potential payments and the likelihood that the payments will be received. The
Company utilizes either the most likely amount method or expected value method to estimate variable consideration to
include in the transaction price based on which method better predicts the amount of consideration expected to be received.
The amount included in the transaction price is constrained to the amount for which it is probable that a significant reversal
of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, the Company re-
evaluates the estimated variable consideration included in the transaction price and any related constraint, and if necessary,
adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis in
the period of adjustment.

After the transaction price is determined it is allocated to the identified performance obligations based on the

estimated standalone selling price. The Company must develop assumptions that require judgment to determine the
standalone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions
to determine the standalone selling price, which may include other comparable transactions, pricing considered in
negotiating the transaction, probabilities of technical and regulatory success and the estimated costs. Certain variable
consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable
consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated to each
performance obligation are consistent with the amounts the Company would expect to receive for each performance
obligation.

The Company then recognizes as revenue in the amount of the transaction price that is allocated to the respective

performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over
time based on the use of an input method.

Licenses of intellectual property:  If a license to the Company’s intellectual property is determined to be distinct 
from the other promises or performance obligations identified in the arrangement, the Company recognizes revenue from 
non-refundable, upfront fees allocated to the license when the license is transferred to the customer and the customer is 
able to use and benefit from the license. For licenses that are combined with other promises, such as research and 
development services and a research license, 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. The measure of progress, and thereby periods over which revenue should be recognized, are subject to 
estimates by management and may change over the course of the research and development and licensing agreement.

Research and Development Services:  The promises under the Company’s collaboration agreements may include 
research and development services to be performed by the Company on behalf of the partner. Payments or reimbursements 
resulting from the Company’s research and development efforts are recognized as the services are performed and presented 
on a gross basis because the Company is the principal for such efforts.

F-13

Table of Contents

Customer Options:  The Company evaluates the customer options to obtain additional items (i.e. additional 
license rights) for material rights, or options to acquire additional goods or services for free or at a discount. Optional 
future services that reflect their standalone selling prices do not provide the customer with a material right and, therefore, 
are not considered performance obligations and are accounted for as separate contracts. If optional future services include a 
material right, they are accounted for as performance obligations. The Company determines an estimated standalone selling 
price of any material rights for the purpose of allocating the transaction price. The Company considers factors such as the 
identified discount and the probability that the customer will exercise the option. Amounts allocated to a material right are 
not recognized as revenue until, at the earliest, the option is exercised or expires.

Milestone payments:  The Company’s collaboration agreements may include development and regulatory 

milestones. The Company evaluates whether the milestones are considered probable of being reached and estimates the 
amount to be included in the transaction price using the most likely amount method. 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. If it is probable that a significant revenue reversal would not occur, the associated milestone 
value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee’s 
control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At 
the end of each reporting period, the Company re-evaluates the probability of achievement of such milestones and any 
related constraint, and if necessary, adjusts the estimate of the overall transaction price. Any such adjustments are recorded 
on a cumulative catch-up basis, which would affect collaboration revenue and net loss in the period of adjustment.

Royalties:  For sales-based royalties, including milestone payments based on the level of sales, the Company 

determines whether the sole or predominant item to which the royalties relate is a license. When the license is the sole or 
predominant item to which the sales-based royalty relates, 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 sales-based royalty revenue resulting from 
the Company’s collaboration agreements.

The Company receives payments from customers based on billing schedules established in each contract. Up-front

payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations
under these arrangements. Amounts are recorded as accounts receivable when the Company’s right to consideration is
unconditional, such as when the Company has a contractual right to payment per the terms of the contract.

Government grants

From time to time, the Company may enter into arrangements with governmental entities for the purposes of
obtaining funding for research and development activities. The Company recognizes government grant funding in the
consolidated statements of operations and comprehensive loss as the related expenses being funded are incurred. The
Company classifies government grants received under these arrangements as a reduction to the related research and
development expense incurred. The Company analyzes each arrangement on a case-by-case basis. For the years ended
December 31, 2020 and 2019, the Company recognized $0.7 million and $0.6 million, respectively, as a reduction of
research and development expense related to government grant arrangements. There were no grant proceeds recognized for
the year ended December 31, 2018.

Research and development costs

Research and development costs are expensed as incurred. Research and development expenses consist of costs

incurred in performing research and development activities, including salaries, share-based compensation and benefits,
travel, facilities costs, materials and laboratory supplies, and external costs of outside vendors engaged to conduct
preclinical development, clinical development activities, as well as to manufacture clinical trial materials. Facilities costs
primarily include the allocation of rent, utilities, and depreciation.

F-14

Table of Contents

Non-refundable prepayments for goods or services that will be used or rendered for future research and

development activities are deferred and capitalized until the related goods are delivered or the related services are
performed, or until it is no longer expected that the goods will be delivered, or the services rendered.

Research and manufacturing contract costs and accruals

The Company has entered into various research and development and manufacturing contracts, including
contracts with respect to preclinical studies and clinical trials, with companies both inside and outside of the United States.
These agreements are generally cancelable with 90 days or less notice, and related costs are recorded as research and
development expenses as incurred. The Company records accruals for estimated ongoing costs. When evaluating the
adequacy of the accrued liabilities, the Company analyzes progress of the research and development and manufacturing
activities, including the phase or completion of events, invoices received and contracted costs. Significant judgments and
estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from
the Company’s estimates. The Company’s historical accrual estimates have not been materially different from the actual
costs.

Research and development incentives and receivable

The Company, through its subsidiaries in the United Kingdom, receives reimbursements of certain research and

development expenditures as part of a United Kingdom government’s research and development tax reliefs program. Under
the program, the Company is able to surrender trading losses that arise from qualifying research and development expenses
incurred by the Company’s subsidiaries in the United Kingdom for a tax credit of up to 14.5% of the surrenderable losses.

Management has assessed the Company’s research and development activities and expenditures to determine

which activities and expenditures are likely to be eligible under the research and development incentive program described
above. At each period end, management estimates the reimbursement available to the Company based on available
information at the time.

The Company recognizes income from the research and development incentives when the relevant expenditure
has been incurred, the associated conditions have been satisfied and there is reasonable assurance that the reimbursement
will be received. The Company records these research and development incentives as a reduction to research and
development expenses in the statements of operations and comprehensive loss, as the research and development tax credits
are not dependent on us generating future taxable income, the Company’s ongoing tax status, or tax position. The research
and development incentives receivable represent an amount due in connection with the above program. The Company
recorded a reduction to research and development expense of $9.1 million, $6.7 million and $5.9 million during the years
ended December 31, 2020, 2019 and 2018, respectively.

Patent costs

All patent-related costs incurred in connection with preparing, filing and prosecuting patent applications are
expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified as
general and administrative expenses in the consolidated statements of operations and comprehensive loss.

Share-based compensation

The Company measures all equity awards granted to employees and directors based on the fair value on the date

of grant. Compensation expense of those awards is recognized over the requisite service period, which is generally the
vesting period of the respective award. The Company records the expense for awards with only service-based vesting
conditions using the straight-line method. The Company accounts for forfeitures as they occur.

The Company has granted awards with both a service condition that vest over time and a performance condition

that will accelerate vesting upon the achievement of a specified collaboration revenue threshold. For equity awards that
contain both performance and service conditions, the Company recognizes share-based compensation expense using an

F-15

Table of Contents

accelerated attribution model over the requisite service period when the achievement of a performance-based milestone is
probable based on the relative satisfaction of the performance condition as of the reporting date.

For share-based awards granted to non-employee consultants, the measurement date for non-employee awards is

the date of grant. The compensation expense is then recognized over the requisite service period, which is the vesting
period of the respective award, without subsequent changes in the fair value of the award.

The fair value of each restricted ordinary share award is based on the fair value of the Company’s ordinary shares,
less any applicable purchase price. The fair value of each share option is estimated using the Black-Scholes option-pricing
model, which requires inputs based on certain subjective assumptions, including the fair value of ordinary shares, the
expected share price volatility, the expected term of the award, the risk-free interest rate, and expected dividends.

Prior to the IPO, the Company utilized significant estimates and assumptions in determining the fair value of its

common stock. Given the absence of an active market for the Company’s ordinary shares, the board of directors
determined the estimated fair value of the Company’s equity instruments based on input from management which utilized
the most recently available independent third-party valuation, and considering a number of objective and subjective factors,
including external market conditions affecting the biotechnology industry sector. The third party valuation reports
performed utilized various valuation methodologies in accordance with the framework of the American Institute of
Certified Public Accountants’ Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as
Compensation, to estimate the fair value of its ordinary shares. Each valuation methodology includes estimates and
assumptions that require judgment. These estimates and assumptions include a number of objective and subjective factors
in determining the value of the Company’s ordinary shares at each grant date, including the following: (1) prices paid for
the Company’s convertible preferred shares, which the Company had sold to outside investors in arm’s-length transactions,
and the rights, preferences, and privileges of the Company’s convertible preferred shares and ordinary shares; (2) the
Company’s stage of development; (3) the fact that the grants of share-based awards involved illiquid securities in a private
company; and (4) the likelihood of achieving a liquidity event for the ordinary shares underlying the share-based awards,
such as an IPO or sale of the Company, given prevailing market conditions.

Expected volatility is calculated based on reported volatility data for a representative group of publicly traded

companies for which historical information was available. The historical volatility is calculated based on a period of time
commensurate with the assumption used for the expected term. The risk-free interest rate is based on the U.S. Treasury
yield curve in effect at the time of grant commensurate with the expected term assumption. The Company uses the
simplified method, under which the expected term is presumed to be the midpoint between the vesting date and the end of
the contractual term. The Company utilizes this method due to the lack of historical exercise data and the plain nature of its
share-based awards. The Company uses the remaining contractual term for the expected life of non-employee awards. The
expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay
any dividends on ordinary shares.

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 payroll costs are classified or in which the award
recipient’s service payments are classified.

Comprehensive loss

Comprehensive loss includes net loss as well as other changes in shareholders’ equity (deficit) that result from
transactions and economic events other than those with shareholders. The Company records unrealized gains and losses
related to foreign currency translation as a component of other comprehensive loss in the consolidated statements of
operations and comprehensive loss.

Contingencies

Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are

recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. At each

F-16

Table of Contents

reporting date, the Company evaluates whether or not a potential loss amount or a potential loss range is probable and
reasonably estimable under the provisions of the authoritative guidelines that address accounting for contingencies. The
Company expenses costs as incurred in relation to such legal proceedings as general and administrative expense within the
consolidated statements of operations and comprehensive loss.

Income taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of

deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the
consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the
basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted
tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities
are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be
recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is
more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established
through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future
taxable profits expected and considering prudent and feasible tax planning strategies.

The Company accounts for uncertainty in income taxes recognized in the consolidated 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 taxing 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 consolidated financial statements. The amount of the benefit that may be recognized is the
largest amount that will more likely than not be 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.

Net loss per share

The Company follows the two-class method when computing net loss per share as the Company has issued shares

that meet the definition of participating securities. The two-class method determines net loss per share for each class of
ordinary and preferred securities according to dividends declared or accumulated and participation rights in undistributed
earnings. The two-class method requires income available to ordinary shareholders for the period to be allocated between
ordinary and preferred securities based upon their respective rights to receive dividends as if all income for the period had
been distributed.

Basic net loss per share attributable to ordinary shareholders is computed by dividing the net loss attributable to

ordinary shareholders by the weighted average number of ordinary shares outstanding for the period. Diluted net loss
attributable to ordinary shareholders is computed by adjusting net loss attributable to ordinary shareholders to reallocate
undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per share attributable to ordinary
shareholders is computed by dividing the diluted net loss attributable to ordinary shareholders by the weighted average
number of ordinary shares outstanding for the period, including potential dilutive ordinary shares assuming the dilutive
effect of ordinary share equivalents.

Prior to the Company’s IPO, convertible preferred shares contractually entitled the holders of such shares to

participate in dividends but contractually do not require the holders of such shares to participate in losses of the Company.
Accordingly, in periods in which the Company reported a net loss, such losses were not allocated to such preferred
securities. In periods in which the Company reported 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.

Recently Issued Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU

2016-13”). ASU 2016-13 will change how companies account for credit losses for most financial assets and certain other
instruments. For trade receivables, loans and held-to-maturity debt securities, companies will be required to recognize an
allowance for credit losses rather than reducing the carrying value of the asset. In November 2019, the FASB issued ASU
No. 2019-10, Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic
842): Effective Dates to amend the effective date of ASU 2016-13, for entities eligible to be “smaller reporting 
companies,” as defined by the SEC, to be effective for fiscal years beginning after December 15, 2022, including interim 
periods within those fiscal years. Early adoption is permitted. The Company has not elected to early adopt ASU No. 2016-
13. The Company is currently evaluating the potential impact that the adoption of ASU 2016-13 will have on the 
Company’s financial position and results of operations.  

In 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income

Taxes (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes and will be effective beginning after
December 15, 2020. The Company is currently evaluating the impact of ASU 2019-12 in the consolidated financial
statements.

On September 30, 2020 (the “Closing Date”), Bicycle Therapeutics plc and its subsidiaries (the “Borrowers”)

entered into the Loan Agreement with Hercules, which provided for aggregate maximum borrowings of up to $40.0
million, consisting of (i) a term loan of $15.0 million, which was funded on the Closing Date, (ii) subject to customary
conditions, an additional term loan of up to $15.0 million available from the Closing Date through March 15, 2021, and
(iii) subject to the Borrowers achieving certain performance milestones and satisfying customary conditions and available
until March 15, 2022, an additional term loan of $10.0 million.

Borrowings under the Loan Agreement bear interest at an annual rate equal to the greater of (i) 8.85% or (ii)

5.60% plus the Wall Street Journal prime rate. Payments under the Loan Agreement are interest-only until the first
principal payment is due on November 1, 2022 (or if the Borrowers achieve the certain performance milestones, the
interest only period is extended with the first principal payment due on May 1, 2023), followed by equal monthly payments
of principal and interest through the scheduled maturity date on October 1, 2024 (the “Maturity Date”). At the Borrowers’
option, the Borrowers may prepay all or any portion greater than $5.0 million of the outstanding borrowings, subject to a
prepayment premium equal to (i) 2.0% of the principal amount outstanding if the prepayment occurs during the first year
following the Closing Date, (ii) 1.5% of the principal amount outstanding if the prepayment occurs during the second year
following the Closing Date, and (iii) 1.0% of the principal amount outstanding if the prepayment occurs thereafter but prior
to the Maturity Date. The Loan Agreement also provides for an end of term charge (the “End of Term Charge”), payable
upon maturity or the repayment of obligations under the Loan Agreement, equal to 5.0% of the principal amount repaid.

Borrowings under the Loan Agreement are collateralized by substantially all of the Borrower’s personal property

and other assets, other than their intellectual property.  Hercules has a perfected first-priority security interest in certain
cash accounts. The Loan Agreement contains customary affirmative and restrictive covenants and representations and
warranties, including a covenant against the occurrence of a change in control, as defined in the agreement. There are no
financial covenants. The Loan Agreement also includes customary events of default, including payment defaults, breaches
of covenants following any applicable cure period, cross acceleration to third-party indebtedness, certain events relating to
bankruptcy or insolvency, and the occurrence of certain events that could reasonably be expected to have a material adverse
effect. Upon the occurrence of an event of default, a default interest rate of an additional 5.0% may be applied to the
outstanding principal and interest payments due, and Hercules may declare all outstanding obligations immediately due and
payable and take such other actions as set forth in the Loan Agreement. The Company has determined that the risk of
subjective acceleration under the material adverse events clause is not probable and therefore has classified the outstanding
principal in long-term liabilities based on scheduled principal payments.

The Company incurred fees and transaction costs totaling $0.6 million associated with the initial term loan, which

are recorded as a reduction to the carrying value of the long-term debt in the consolidated balance sheets. The fees,
transaction costs, and the End of Term Charge are amortized to interest expense through the Maturity Date using the
effective interest method. The effective interest rate was 12.2% at December 31, 2020. The Company assessed all terms
and features of the Loan Agreement in order to identify any potential embedded features that would require bifurcation. As
part of this analysis, the Company assessed the economic characteristics and risks of the debt. The

F-19

 
    
    
 
 
 
 
 
 
 
 
 
Table of Contents

Company determined that all features of the Loan Agreement are clearly and closely associated with a debt host and, as
such, do not require separate accounting as a derivative liability. Interest expense for the year ended December 31, 2020
related to the Loan Agreement with Hercules was $0.4 million.

In addition, the Company granted Hercules the right to purchase up to an aggregate of $2.0 million of the
Company’s equity securities sold to investors in certain subsequent financing upon the same terms and conditions afforded
to such other investors. On October 1, 2020, Hercules purchased 98,100 ADSs, representing the same number of ordinary
shares, at a public offering price of $19.05 per ADS ordinary share pursuant to the Sales Agreement, resulting in net
proceeds of $1.8 million.

7. Convertible preferred shares

Prior to the IPO, the Company issued Series A Preferred Shares, Series B1 Preferred Shares, and Series B2

convertible preferred shares (“Series B2 Preferred Shares”) (collectively the “Preferred Shares”).

On December 20, 2018, the Company completed the issuance of 1,323,248 Series B2 Preferred Shares at a price
per Series B2 Preferred Share of £15.55, for gross cash proceeds of $26.1 million (the “Series B2 Financing”). On January
3, 2019, the Company completed the issuance of 80,385 Series B2 Preferred Shares at a price per share of £15.55, for gross
cash proceeds of $1.6 million.

In May 2019, the Company’s board of directors and shareholders approved the reorganization of the Company’s

share capital by issuing ordinary shares as bonus shares to each holder of ordinary shares on the basis of 1.429 bonus
shares for each ordinary share in issue (having the effect of a one for 1.429 share split (without having an impact on the
nominal value of the ordinary shares)), which was effected on May 13, 2019 (the “Share Capital Reorganization”). All
issued and outstanding share and per share amounts of ordinary shares and share options included in the accompanying
consolidated financial statements have been adjusted to reflect this share split for all periods presented. Upon the closing of
the IPO in May 2019, all of the Company’s outstanding convertible preferred shares automatically converted into
11,647,529 ordinary shares on a 1:1.429 basis.

8. Warrant liability

In 2017, the Company issued 200,000 warrants to subscribe for Series A Preferred Shares, at £0.01 each. In
conjunction with the completion of the IPO, 120,000 warrants to subscribe for Series A Preferred Shares were exercised for
171,480 ordinary shares. The remaining 80,000 warrants, which were exercisable into 114,320 ordinary shares following
the completion of the IPO, as adjusted for the impact of the Share Capital Reorganization (Note 7), were exercised in 2019
and 2020.

F-20

    
Table of Contents

In addition, in 2017, the Company issued a total of 743,287 warrants to subscribe for Series B1 Preferred Shares,

with an exercise price of £0.01, in conjunction with the issuance of 3,947,198 Series B1 Preferred Shares.

On March 7, 2019, the holders of the warrants to subscribe for Series B1 Preferred Shares agreed that 50% of the
warrants would be exercised in conjunction with the IPO and 50% of the warrants would expire. The modification resulted
in an incremental change in fair value of $0.1 million, which is included in other expense for the year ended December 31,
2019. On May 28, 2019, in conjunction with the completion of the IPO, all Series B1 Preferred share warrants were
exercised for 531,077 ordinary shares, as adjusted for the impact of the Share Capital Reorganization (Note 7).

Prior to the completion of the IPO, the warrants to subscribe for Series A and Series B1 Preferred Shares were

recorded as a liability and remeasured to fair value at each reporting date. Changes in the fair value of the warrant liability
were recognized as other expense, net in the consolidated statements of operations and comprehensive loss. Upon the
closing of the IPO on May 28, 2019, warrants that were not exercised in conjunction with the IPO automatically became
warrants to subscribe for ordinary shares, and meet the criteria to be classified as shareholders’ equity (deficit). As such,
following the final remeasurement on May 28, 2019, the Company reclassified the carrying value of the warrant liability to
additional paid-in-capital in the consolidated balance sheet.

9. Ordinary shares

Each holder of ordinary shares is entitled to one vote per ordinary share and to receive dividends when and if such
dividends are recommended by the board of directors and declared by the shareholders. Holders of ADSs are not treated as
holders of the Company’s ordinary shares, unless they withdraw the ordinary shares underlying their ADSs in accordance
with the deposit agreement and applicable laws and regulations. The depositary is the holder of the ordinary shares
underlying the ADSs. Holders of ADSs therefore do not have any rights as holders of the Company’s ordinary shares, other
than the rights that they have pursuant to the deposit agreement with the depositary. As of December 31, 2020 and 2019,
the Company has not declared any dividends.

As of December 31, 2020 and 2019, the Company’s authorized capital share consisted of 31,995,653 ordinary

shares, with a nominal value of £0.01 per share.

10. Share-based compensation

Employee incentive pool

2020 Share Option Plan

In June 2020, the Company’s shareholders approved the Bicycle Therapeutics plc 2020 Equity Incentive Plan (the 

“2020 Plan”), under which the Company may grant market value options, market value stock appreciation rights or 
restricted shares, restricted share units, performance restricted share units and other share-based awards to the Company’s 
employees. The Company’s non-employee directors and consultants are eligible to receive awards under the 2020 Non-
Employee Sub-Plan to the 2020 Plan. All awards under the 2020 Plan, including the 2020 Non-Employee Sub-Plan, will be 
set forth in award agreements, which will detail the terms and conditions of awards, including any applicable vesting and 
payment terms, change of control provisions and post-termination exercise limitations. In the event of a change of control 
of the Company, as defined in the 2020 Plan, any outstanding awards under the 2020 Plan will vest in full immediately 
prior to such change of control. Share options issued under the 2020 Share Option Plan have a 10 year contractual life, and 
generally vest over either a three year service period for non-employee directors, or a four year service period with 25% of 
the award vesting on the first anniversary of the commencement date and the balance thereafter in 36 equal monthly 
installments for employees and consultants.  Certain options granted to the Company’s non-employee directors vest 
immediately upon grant.

The Company initially reserved up to 4,773,557 ordinary shares for future issuance under the 2020 Plan,

representing 574,679 new shares, 544,866 shares that remained available for future issuance under the Company’s 2019
Share Option Plan (the “2019 Plan”) immediately prior to the effectiveness of the 2020 Plan and up to 3,654,012 shares

F-21

Table of Contents

subject to options that were granted under the 2019 Plan and that were granted pursuant to option contracts granted prior to
the Company’s IPO, in each case that expire, terminate, are forfeited or otherwise not issued from time to time, if any.
Additionally, the number of ordinary shares reserved for issuance pursuant to the 2020 Plan will automatically increase on
the first day of January of each year, commencing on January 1, 2021, in an amount equal to 5% of the total number of the
Company’s ordinary shares outstanding on the last day of the preceding year, or a lesser number of shares determined by
the Company’s board of directors. As of December 31, 2020, there were 4,699,470 shares available for issuance and
options to purchase 196,550 shares outstanding under the 2020 Plan. The number of shares reserved for issuance under the
2020 Plan was increased by 1,054,727 shares effective January 1, 2021.

2019 Share Option Plan

In May 2019, the Company adopted the 2019 Plan, which became effective in conjunction with the IPO.  As of 

December 31, 2020, there were 2,594,277 options to purchase ordinary shares outstanding under the 2019 Plan. In 
conjunction with the adoption of the 2020 Plan, all shares available for future issuance under the 2019 Plan as of June 29, 
2020 became available for issuance under the 2020 Plan and the Company ceased making awards under the 2019 Plan. The 
2020 Plan is the successor of the 2019 Plan.

Share options previously issued under the 2019 Share Option Plan have a 10 year contractual life, and generally
either vest monthly over a three year service period, or over a four-year service period with 25% of the award vesting on
the first anniversary of the commencement date and the balance thereafter in 36 equal monthly installments. Certain awards
granted to the Company’s non-employee directors were fully vested on the date of grant. The exercise price of share
options issued under the 2019 Share Option Plan is not less than the fair value of ordinary shares as of the date of grant.

Pre-IPO Share Options and restricted shares

Prior to the IPO, the Company issued share options and ordinary shares, as administered by the board of directors,
using standardized share option and share subscription agreements. To the extent such incentives were in the form of share
options, the options may have been granted pursuant to a potentially tax-favored Enterprise Management Incentive, or
EMI, scheme available to U.K. employees, directors and consultants of the Company. Upon completion of the IPO, shares
reserved for future issuance outside of the 2019 Share Option Plan were cancelled.

Options granted, as well as restricted shares granted as employee incentives prior to the IPO, typically vest over a
four‑year service period with 25% of the award vesting on the first anniversary of the commencement date and the balance
thereafter in 36 equal monthly installments and expire no later than 10 years from the date of grant.

Certain equity awards were issued in 2017 and 2018 for which 20% of the award vests upon the first anniversary
of the vesting start date, 60% vests thereafter in 36 equal monthly installments, and 20% vest upon the earlier of the fourth
anniversary of the vesting start date, or the achievement of a specified revenue threshold from the Company’s collaboration
arrangements.

Options issued to U.K. employees prior to the IPO generally had an exercise price of £0.01 per share. The exercise

price for share options granted to U.S. employees, had an exercise price that was not less than the fair value of ordinary
shares as determined by the board of directors as of the date of grant. Prior to the IPO, the Company’s board of directors
valued the Company’s ordinary shares based on input from management, considering the most recently available valuation
of ordinary share performed by an independent third‑party valuation firm as well as additional factors which may have
changed since the date of the most recent contemporaneous valuation through the date of grant.

Employee Share Purchase Plan (“ESPP”)

In May 2019, the Company adopted the 2019 Employee Stock Purchase Plan (the “ESPP”), which became

effective in conjunction with the IPO. The Company initially reserved 215,000 ordinary shares for future issuance under
this plan. The ESPP provides that the number of shares reserved and available for issuance will automatically increase each
January 1, beginning on January 1, 2020 and each January 1 thereafter through January 1, 2029, by the least of (i)

F-22

Table of Contents

1% of the outstanding number of ordinary shares on the immediately preceding December 31; (ii) 430,000 ordinary shares
or (iii) such lesser number of shares as determined by the Compensation Committee. The number of shares reserved under
the ESPP is subject to adjustment in the event of a split-up, share dividend or other change in our capitalization. As of
December 31, 2020, the total number of shares available for issuance under the ESPP was 394,937 ordinary shares. The
number of shares reserved for issuance under the ESPP was increased by 210,945 shares effective January 1, 2021.

Once the Company commences offerings under the ESPP, each offering to the employees to purchase shares under
the ESPP will begin on each June 1 and December 1 and will end on the following November 30 and May 31, respectively.
On each purchase date, which will fall on the last date of each offering period, ESPP participants will purchase ordinary
shares at a price per share equal to 85% of the lesser of (1) the fair market value of the shares on the offering date or (2) the
fair market value of the shares on the purchase date. The occurrence and duration of offering periods under the ESPP are
subject to the determinations of the Company’s compensation committee. As of December 31, 2020, there have been no
offering periods to employees under ESPP.

The weighted average grant-date fair value of share options granted during the years ended December 31, 2020,

2019 and 2018 was $7.87 per share, $6.07 per share and $3.73 per share, respectively.

For the years ended December 31, 2020, 2019 and 2018, the Company recorded share-based compensation

expense for share options granted of $6.5 million, $2.7 million and $0.8 million, respectively. Expense for non-employee
consultants for the years ended December 31, 2020, 2019 and 2018, was immaterial.

The aggregate intrinsic value of share options is calculated as the difference between the exercise price of the

share options and the fair value of the Company’s ordinary shares. The aggregate intrinsic value of share options exercised
during the years ended December 31, 2020, 2019 and 2018 was $1.3 million, $0.6 million and $23,000 respectively.

During the year ended December 31, 2018, the Company granted share options to purchase 70,875 ordinary shares
with performance based vesting, for which 20% of the award vests upon the first anniversary of the vesting start date, 60%
vests thereafter in 36 equal monthly installments, and 20% on the earlier of the fourth anniversary of the vesting start date,
or the achievement of a specified revenue threshold from the Company’s collaboration arrangements. In May 2018, the
Company determined that the performance condition became probable of achievement and recorded a cumulative catch-up
to reflect the expense as if the vesting condition was probable of achievement at the time of the grant of the award. The
Company recorded expense of $0.1 million, $0.1 million and $0.7 million, during the years ended December 31, 2020,
2019 and 2018, respectively, related to awards with performance based vesting, which includes the acceleration of vesting
expense.

As of December 31, 2020, total unrecognized compensation expense related to the unvested employee and

director share-based awards was $13.7 million, which is expected to be recognized over a weighted average period of
2.5 years.

Restricted shares

Prior to the IPO, the Company granted restricted shares with service-based vesting conditions. In conjunction with
the IPO in May 2019, the board of directors modified the vesting terms to accelerate vesting for all then unvested restricted
shares. As a result, the Company recorded $0.2 million of expense upon the modification of the restricted shares during the
year ended December 31, 2019.

For the years ended December 31, 2020, 2019 and 2018, the Company recorded share-based compensation of

zero, $0.4 million, and $0.2 million, respectively, for unvested restricted shares granted.

The fair value of employee restricted share awards vested during the years ended December 31, 2020, 2019 and
2018, based on estimated fair values of the ordinary shares underlying the restricted share awards on the day of vesting,
was zero, $0.7 million and $0.2 million, respectively. As of December 31, 2020, there was no unrecognized compensation
cost related to the unvested employee and director restricted share awards.

On February 21, 2020, the Company entered into a Discovery Collaboration and License Agreement (the
“Genentech Collaboration Agreement”) with Genentech. The collaboration is focused on the discovery and development of
Bicycle peptides directed to biological targets selected by Genentech and aimed at developing up to four potential
development candidates against multiple immuno-oncology targets suitable for Genentech to advance into further
development and commercialization.

Under the terms of the Genentech Collaboration Agreement, Bicycle received a $30.0 million upfront, non-

refundable payment. The initial discovery and optimization activities will focus on utilizing Bicycle’s phage screening
technology to identify product candidates aimed at two immuno-oncology targets (“Genentech Collaboration Programs”),
which may also include additional discovery and optimization of Bicycles as a targeting elements for each Genentech
Collaboration Program (each a “Targeting Arm”). Genentech has the option to nominate up to two additional immuno-
oncology targets (each, an “Expansion Option”), which may also include an additional Targeting Arm for each Expansion
Option, as additional Genentech Collaboration Programs during a specified period following completion of certain
activities under an agreed research plan. If Genentech exercises one or more Expansion Options, Genentech will pay to the
Company an expansion fee of $10.0 million per Expansion Option. Genentech also has rights, under certain limited
circumstances, to select an alternative target to be the subject of a Genentech Collaboration Program, in some cases subject
to payment of an additional target selection fee.

If Genentech elects for Bicycle to perform discovery and optimization services for certain Targeting Arms, the 

Company will be entitled to receive an additional advance payment for the additional research services.  Genentech 
exercised its right to select a Targeting Arm for one of the initial Genentech Collaboration Programs at the inception of the 
arrangement, which entitled the Company to an additional $1.0 million payment. If a Targeting Arm achieves specified 
criteria in accordance with the research plan, Genentech will be required to pay a further specified amount in the low single 
digit millions for each such Targeting Arm as consideration for the additional services to be provided.  

Bicycle granted to Genentech a non-exclusive research license under Bicycle’s intellectual property solely to

enable Genentech to perform any activities under the agreement. The activities under the Genentech Collaboration
Agreement are governed by a joint research committee (“JRC”) with representatives from each of the Company and
Genentech. The JRC will oversee, review and recommend direction of each Genentech Collaboration Program,
achievement of development criteria, and variations of or modifications to the research plans.

After the Company performs the initial discovery and optimization activities in accordance with an agreed

research plan and achieves specified criteria, Genentech will have the option to have the Company perform initial pre-

F-25

 
    
    
    
 
 
Table of Contents

clinical development and optimization activities in exchange for an additional specified milestone payment in the mid-
single digit millions for each Genentech Collaboration Program (the “LSR Go Option”).  Upon completion of such initial 
pre-clinical development and optimization activities for each Genentech Collaboration Program, Genentech will have the 
option to obtain an exclusive license to exploit any compound developed under such Genentech Collaboration Program in 
exchange for an additional specified payment in the mid to high single digit millions for each of the initial two Genentech 
Collaboration Programs and each of the two Expansion Option Genentech Collaboration Programs (the “Dev Go Option”). 

On a Genentech Collaboration Program by Genentech Collaboration Program basis, if Genentech elects to obtain

exclusive development and commercialization rights and pays the applicable LSR Go Option and Dev Go Option fees,
Genentech will be required to make milestone payments to the Company upon the achievement of specified development,
regulatory, and initial commercialization milestones for products arising from each collaboration program, totaling up to
$200.0 million. Specifically, the Company is eligible for additional development milestones totaling up to $65.0 million, as
well as regulatory milestones of up to $135.0 million for each collaboration program. In addition, the Company is also
eligible to receive up to $200.0 million in sales milestone payments on a Genentech Collaboration Program-by-Genentech
Collaboration Program basis. In addition, to the extent any of the product candidates covered by the licenses conveyed to
Genentech are commercialized, the Company would be entitled to receive tiered royalty payments on net sales at
percentages ranging from the mid-single to low double-digits, subject to certain standard reductions and offsets. Royalties
will be payable, on a product by product and country by country basis, until the later of the expiration of specified licensed
patents covering such product in such country, or ten years from first commercial sale of such product in such country.

Accounting Analysis

Upon the execution of the Genentech Collaboration Agreement, the Company has identified the following

performance obligations:

(i)

(ii)

(iii)

(iv)

(v)

(vi)

Research license, and the related research and development and preclinical services through LSR Go for
a first Genentech Collaboration Program (Genentech Collaboration Program #1);

Research license, and the related research and development and preclinical services through LSR Go for
a second Genentech Collaboration Program with a specified Targeting Arm (Genentech Collaboration
Program #2);

Material right associated with an option to a specified Targeting Arm for Genentech Collaboration
Program #1;

Two material rights associated with the LSR Go Option for Genentech Collaboration Program #1 and
Genentech Collaboration Program #2, which includes research services to be provided through the Dev
Go Option and an option to receive an exclusive license;

Material rights associated with certain limited substitution rights with respect to a limited number of
collaboration targets;

Two material rights related to each Genentech Expansion Option, which upon exercise include the
services for an additional immuno-oncology target through the LSR Go Option, an LSR Go Option
which includes the services to be provided through the Dev Go Option and an option to receive an
exclusive license, limited substitution rights, and an option to select a specified Targeting Arm.

The Company concluded that certain substitution rights that require the payment of additional consideration, 

which approximate the standalone selling price of the underlying services to be provided, do not provide the customer with 
a material right and therefore, are not considered as performance obligations and are accounted for as separate contracts 
upon exercise, if ever.  The Company’s participation in the joint steering committee was assessed as immaterial in the 
context of the contract. 

F-26

Table of Contents

The Company has concluded that the research license is not distinct from the research and development services

as Genentech cannot obtain the benefit of the research license without the Company performing the research and
development services. The services incorporate proprietary technology and unique skills and specialized expertise,
particularly as it relates to constrained peptide technology that is not available in the marketplace. As a result, for each
research program, the research license has been combined with the research and development services into a single
performance obligation. In addition, the Company concluded that the Dev Go Option is not distinct or separately
exercisable from the LSR Go Option, as the customer cannot benefit from the Dev Go Option unless and until the LSR Go
Option is exercised.

In assessing whether the various options under the Genentech Collaboration Agreement represent material rights, 

the Company considered the additional consideration the Company would be entitled to upon the option exercise, the 
standalone selling price of the underlying goods, services, and additional options.  For the material rights identified above 
the Company concluded that each of the options provided Genentech with a discount that it otherwise would not have 
received. 

The total transaction price was initially determined to be $31.0 million, consisting of the $30.0 million upfront fee 

and the additional $1.0 million for Genentech’s selection of a new Targeting Arm at inception.  The Company utilizes the 
most likely amount method to determine the amount of research and development funding to be received. Additional 
consideration to be paid to the Company upon the exercise of options by Genentech and subsequent milestones are 
excluded from the transaction price as they relate to option fees and milestones that can only be achieved subsequent to the 
exercise of an option. In addition, other variable consideration for development milestones not subject to option exercises 
was fully constrained, as a result of the uncertainty regarding whether any of the milestones will be achieved. 

The transaction price was allocated to the performance obligations based on the relative estimated standalone 
selling prices of each performance obligation. The estimated standalone selling prices for the Genentech Collaboration 
Programs was based on the nature of the services to be performed and estimates of the associated effort and costs of the 
services, adjusted for a reasonable profit margin for what would be expected to be realized under similar contracts. The 
estimated standalone selling price for the material rights was determined based on the fees Genentech would pay to 
exercise the options, the estimated value of the underlying goods and services, and the probability that Genentech would 
exercise the option and any underlying options.  Based on the relative standalone selling price, the allocation of the 
transaction price to the separate performance obligations is as follows (in thousands):

Allocation of 

Performance Obligations
Genentech Collaboration Program #1 Performance Obligation
Genentech Collaboration Program #2 Performance Obligation
Specified Targeting Arm Material Right Arm for Genentech Collaboration Program #1

The Company will recognize revenue related to amounts allocated to the Genentech Collaboration Program #1

and #2 Performance Obligations as the underlying services are performed using a proportional performance model over the
period of service using input-based measurements of total full-time equivalent efforts and external costs incurred to date as
a percentage of total full-time equivalent time and external expected, which best reflects the progress towards satisfaction
of the performance obligation. The amount allocated to the material rights is recorded as deferred revenue and the
Company will commence revenue recognition upon exercise of or upon expiry of the respective option. The Company
anticipates that the Genentech Collaboration Performance Program #1 and #2 obligations will be performed over a period
of approximately two years, and the material rights will be exercised or expire within approximately four years from
contract execution.

F-27

 
 
 
Table of Contents

During the year ended December 31, 2020, the Company recognized revenue of $4.9 million, and as of December

31, 2020, the Company recorded $27.6 million of deferred revenue in connection with the Genentech Collaboration
Agreement.

Dementia Discovery Fund Agreement

In May 2019, the Company entered into a collaboration with the Dementia Discovery Fund (“DDF”) to use
Bicycle technology for the discovery and development of novel therapeutics for dementia (the “DDF Collaboration
Agreement”). In October 2019, the collaboration with DDF was expanded to include Oxford University’s Oxford Drug
Discovery Institute (ODDI). Under the terms of the DDF Collaboration Agreement, the Company and DDF will
collaborate to identify Bicycles that bind to clinically validated dementia targets (the “DDF Research Plan”). The Company
is obligated to use commercially reasonable efforts to perform research activities under the DDF Research Plan. DDF shall
not be directly engaged in the conduct of any research activities under the arrangement. ODDI will then profile these
Bicycles in a range of target-specific and disease-focused assays to determine their therapeutic potential. The activities
under the DDF Collaboration Agreement will be governed by a project advisory panel, composed of two representatives
from the Company and DDF. The Research Advisory Panel will oversee, review and recommend direction for the Research
Plans and variations of or modifications of research plans.

The Company received an upfront payment of $1.1 million in May 2019. The Company may receive up to an

additional $0.7 million, upon achievement of certain milestones such as the identification of lead Bicycle candidates with a
certain affinity, which would be used to fund additional research and development services including lead optimization.

Intellectual property created by the collaboration shall be owned by the Company, and background intellectual

property improvements shall be owned by the party from whose background intellectual property they exclusively relate. If
promising lead compounds are identified, the Company, ODDI and DDF have the option (the “DDF Option”) to establish a
jointly owned new company (“NewCo”) to advance the compounds through further development towards
commercialization. NewCo will receive a royalty and milestone-bearing assignment and license of intellectual property
from the Company for this purpose. The DDF Option is exercisable at any time until 90 days following the completion of
the Research Plan and delivery of a final report. If DDF does not elect to exercise the DDF Option during the Option
period, then DDF shall have no right in the collaboration intellectual property. NewCo will initially be owned 66% by the
Company and 34% by DDF; however, the Company shall not be entitled to exercise more than 50% of the total voting
rights related to its ownership interests. After completion of the DDF Option exercise, for a period of two years following
the option exercise, NewCo shall have the right to initiate a new research program to develop up to three additional
dementia targets, on a target by target basis, and the Company will be entitled to charge NewCo an agreed upon FTE rate
for peptide screening and optimization for the active targets.

Either party may terminate the DDF Collaboration Agreement upon providing not less than 60 days written

notice. A party may terminate the DDF Collaboration Agreement with immediate effect without notice if at any time the
other party files for protection under bankruptcy or insolvency laws, makes an arrangement for the benefit of creditors,
appoints a receiver, administrator, manager or trustee over its property, proposes a written agreement of composition or
extension of its debts, is a party to any dissolution, winding-up or liquidation, or is in material breach that has not been
remedied.

Accounting Analysis

The Company identified a single performance obligation associated with the performance of research and

development services under the DDF Research Plan.

The Company concluded that the DDF Option is an immaterial obligation at the inception of the arrangement, as

it represents a right to acquire shares of NewCo that have de minimis value. The DDF Option also does not contain a
material right that otherwise would not have been received. The Company’s participation in the Research Advisory Panel
was assessed as immaterial in the context of the contract. In addition, the Company concluded that the option for NewCo to
obtain additional peptide screening and optimization services is not an obligation at the inception of the

F-28

Table of Contents

arrangement, as they are optional services and the amount that will be paid for the services do not reflect a discount that the
customer would otherwise receive and do not provide the customer with material rights.

The total transaction price was initially determined to be $1.1 million, consisting of the upfront payment for

research and development funding. The Company may receive additional milestone payments during the DDF Research
Plan, as well as for research and development services for additional targets following the exercise of DDF Option. These
variable amounts are excluded from the transaction price as they relate to fees that can only be achieved subsequent to the
exercise of an option, and therefore are treated as separate contracts.

The transaction price was allocated to the single performance obligation of research and development services.
The Company will recognize revenue as the underlying services are performed using a proportional performance model,
over the period of service using input-based measurements of total costs, including total full-time equivalent effort incurred
to date as a percentage of total costs expected, which best reflects the progress towards satisfaction of the performance
obligation.

For both of the years ended December 31, 2020 and 2019, the Company recognized $0.4 million of revenue. In

December 2020, the Company received a payment of $0.5 million upon the achievement of specified scientific criteria. The
Company concluded that the payment represents consideration for a single performance obligation to perform lead
optimization activities, and will recognize revenue as the underlying services are performed using a proportional
performance model, over the period of service using input based measurements of total costs, including total full time
equivalent effort incurred to date as a percentage of total costs expected, which best reflects the progress towards
satisfaction of the performance obligation. The Company recorded deferred revenue of $0.8 million and $0.7 million for
the years ended December 31, 2020 and 2019, respectively, related to its collaboration with DDF.

Sanofi Collaboration Agreement (formerly Bioverativ)

Summary of Agreement

In August 2017, the Company entered into a Collaboration Agreement with Bioverativ Inc., which was acquired

by Sanofi in March 2018 (“Sanofi”). Under the collaboration agreement with Sanofi (the “Sanofi Collaboration
Agreement”), the Company provided research and development services focused on up to three collaboration programs;
(i) Sickle cell disease, (ii) Hemophilia, and (iii) and had an option to a third program that expired unexercised. The
Company used its bicyclic peptide screening platform to perform research and development services for the programs and
Sanofi had the ability to select a collaboration product for each program and obtain a license to develop and exploit the
selected collaboration product for an additional option fee.

Sanofi could terminate the Sanofi Collaboration Agreement, entirely or on a program by program, licensed
product by licensed product or country by country basis, for convenience upon not less than 30 days prior written notice to
the Company.

Accounting Analysis

The Company identified four performance obligations associated with the Sanofi Collaboration Agreement,

consisting of (i) Sickle Cell Research and Related Services, (ii) Hemophilia Research License and Related Services, (iii) a
Sickle Cell License Option Material Right, and (iv) a Hemophilia License Option Material Right. The total transaction
price consisted of a $10.0 million upfront payment and a non-refundable research and development funding of
$4.2 million. The transaction price was allocated to the performance obligations based on the relative estimated standalone
selling prices of each performance obligation. The Company recognized revenue related to amounts allocated to the Sickle
Cell and Hemophilia Research License and Related Services obligations as the underlying services were performed using a
proportional performance model, over the period of service using input-based measurements of total full-time equivalent
effort incurred to date as a percentage of total full-time equivalent time expected, which best reflected the progress towards
satisfaction of the performance obligation. The amount allocated to the material rights was recorded as deferred revenue,
and the Company commenced revenue recognition when the underlying option was exercised or upon expiry of the option.

F-29

Table of Contents

On March 28, 2019, Sanofi notified the Company that it would not exercise the Sickle Cell License Option. In

addition, the collaboration with Sanofi was terminated effective October 23, 2019. As a result, deferred revenue related to
amounts allocated to the Sickle Cell License Option Material Right of $5.3 million and the Hemophilia License Option
Material Right of $4.7 were recognized during the year ended December 31, 2019.

For the years ended December 31, 2020, 2019 and 2018, the Company recognized zero, $10.7 million, and

$4.0 million, respectively, of collaboration revenue related to its collaboration with Sanofi. As of December 31, 2020 and
2019, the Company recorded zero deferred revenue related to its collaboration with Sanofi.

AstraZeneca Collaboration Agreement

Summary of Agreement — 2016 Agreement

In November 2016, the Company entered into a Research Collaboration Agreement (the “AstraZeneca
Collaboration Agreement”) with AstraZeneca. The collaboration is focused on the research and development of Bicycle
peptides that bind to up to six biological targets. After discovery and initial optimization of such Bicycle peptides,
AstraZeneca will be responsible for all research and development, including lead optimization and drug candidate
selection. AstraZeneca has option rights, at drug candidate selection, which allow it to obtain development and exploitation
license rights with regard to such drug candidate. The initial research obligation focuses on two targets within respiratory,
cardiovascular and metabolic disease. AstraZeneca also had an option to nominate up to four additional targets at any point
up to the second anniversary of the agreement (“Additional Four Target Option”).

Under the terms of the AstraZeneca Collaboration Agreement, the Company granted to AstraZeneca, for each

research program, a right and license (with the right to sublicense) certain background and platform intellectual property,
for the duration of the applicable Research Term, to the extent necessary or useful for AstraZeneca to conduct the activities
assigned to it in the applicable research plan, but for no other purpose.

AstraZeneca has the option to obtain development and commercialization licenses associated with each designated

drug candidate in return for a fee of $8.0 million per drug candidate. In addition, AstraZeneca is required to make certain
milestone payments to the Company upon the achievement of specified development, regulatory and commercial
milestones. More specifically, for each research program, the Company is eligible to receive up to $29.0 million in
development milestone payments and up to $23.0 million in regulatory milestone payments. The Company is also eligible
for up to $110.0 million in commercial milestone payments, on a research program by research program basis.

AstraZeneca may terminate the AstraZeneca Collaboration Agreement, entirely or on a licensed product by

licensed product or country by country basis, for convenience.

Accounting Analysis

The Company has identified the following performance obligations at the inception of the arrangement:

(i)

(ii)

research license and the related research and development services during the Bicycle Research Term for
the first target (the “Target One Research License and Related Services”),

research license and the related research and development services during the Bicycle Research Term for
the second target (the “Target Two Research License and Related Services”).

The Company concluded that the Additional Four Target Option was not a material right, as the option did not

provide a discount that AstraZeneca otherwise would not have received. The Company’s participation in the joint steering
committee was assessed as immaterial in the context of the contract. The Company concluded that the research license is
not distinct from the research and development services during the Bicycle Research Term as AstraZeneca cannot obtain
the benefit of the research license without the Company performing the research and development services. The services
incorporate proprietary technology and unique skills and specialized expertise, particularly as it

F-30

Table of Contents

relates to constrained peptide technology that is not available in the marketplace. As a result, for each research program,
the research license has been combined with the research and development services into a single performance obligation.

The total transaction price was initially determined to be $1.2 million, and was raised to $2.0 million when both

programs were extended, consisting solely of research and development funding. The Company utilizes the most likely
amount method to determine the amount of research and development funding to be received. Additional consideration to
be paid to the Company upon the exercise of the license options by AstraZeneca or upon reaching certain milestones is
excluded from the transaction price as they relate to option fees and milestones that can only be achieved subsequent to the
option exercise or are outside of the initial contact term. The transaction price was allocated to the performance obligations
based on the relative estimated standalone selling prices of each performance obligation. The estimated standalone selling
prices for the Target One and Target Two Research License and Related Services is primarily based on the nature of the
services to be performed and estimates of the associated effort and costs of the services, adjusted for a reasonable profit
margin what would be expected to be realized under similar contracts. The transaction price allocated to each performance
obligation was initially $0.6 million.

The Company recognized revenue related to amounts allocated to the Research License and Related Services as

the underlying services were performed using a proportional performance model over the period of service using input-
based measurements of total full-time equivalent effort incurred to date as a percentage of total full-time equivalent time
expected, which best reflects the progress towards satisfaction of the performance obligation. In October 2020,
AstraZeneca terminated the collaboration activities related to the second target. No revenue was recognized upon
termination.

For the years ended December 31, 2020, 2019 and 2018 the Company recognized zero, $0.2 million, and $1.0
million, respectively, of collaboration revenue related to the Target One and Target Two Research License and Related
Services for its Collaboration Agreement with AstraZeneca. As of December 31, 2020 and 2019, the Company recorded
zero deferred revenue in connection with the 2016 AstraZeneca Collaboration Agreement. In March 2021, AstraZeneca
terminated the collaboration activities related to the first target.

May 2018 AstraZeneca Option Exercise — Additional Four Targets

Under the AstraZeneca Collaboration Agreement, AstraZeneca was granted an option to nominate up to four

additional targets at any point up to the second anniversary of the agreement (“Additional Four Target Option”). In
May 2018, AstraZeneca made an irrevocable election to exercise the Additional Four Target Option. As a result,
AstraZeneca is entitled to obtain research and development services with respect to Bicycle peptides that bind to up to four
additional targets, along with license rights to those selected targets, in exchange for an option fee of $5.0 million.
AstraZeneca is obligated to fund two FTEs during the Bicycle Research Term, for each research program, based on an
agreed upon FTE reimbursement rate. Payment is made quarterly in advance of services being provided. AstraZeneca has
the option to obtain worldwide development and commercialization licenses associated with each designated drug
candidate in return for a fee of $8.0 million per drug candidate, upon the selection of such drug candidate, after which
AstraZeneca would be required to fund development and commercialization costs, and to pay regulatory and commercial
milestone payments and royalties to the Company as for the other products developed under the AstraZeneca Collaboration
Agreement.

Accounting Analysis

Upon the execution of the agreement, the Company has identified the following five performance obligations

associated with the AstraZeneca May 2018 Agreement:

(i)

(ii)

Research license and the related research and development services during the Bicycle Research Term
for the third target (the “Target Three Research License and Related Services”),

Material right associated with the development and exploitation license option for the third target
(“Target Three Material Right”),

F-31

Table of Contents

(iii)

(iv)

(v)

Material right associated with the research services option, including the underlying development and
exploitation license option for the fourth target (“Target Four Material Right”),

Material right associated with the research services option, including the underlying development and
exploitation license option for the fifth target (“Target Five Material Right”), and

Material right associated with the research services option, including the underlying development and
exploitation license option for the sixth target (“Target Six Material Right”).

The Company concluded that the fourth, fifth and sixth targets available for selection are options. Upon exercise,

AstraZeneca will obtain a research license and the related research and development services and an option to a
development and exploitation license. The Company has concluded that the research services option, including the
underlying development and exploitation license options related to each respective target results in a material right as the
option exercise fee related to the development and exploitation license contains a discount that AstraZeneca would not
have otherwise received.

The research license and the related research and development services related to the fourth, fifth and sixth targets
were not performance obligations at the inception of the arrangement, as they are optional services that will be performed if
AstraZeneca selects additional targets and they reflect their standalone selling prices and do not provide the customer with
material rights. The Company’s participation in the joint steering committee was assessed as immaterial in the context of
the contract.

The total transaction price was initially determined to be $5.7 million, consisting of the $5.0 million option
exercise fee and research and development funding of an estimated $0.7 million. The research and development funding is
being provided based on the costs that are incurred to conduct the research and development services. The Company
utilizes the most likely amount method to determine the amount of research and development funding to be received.
Additional consideration to be paid to the Company upon the exercise of the license options by AstraZeneca or upon
reaching certain milestones are excluded from the transaction price as they relate to option fees and milestones that can
only be achieved subsequent to the license option exercise or are outside of the initial contact term.

The transaction price was allocated to the performance obligations based on the relative estimated standalone

selling prices of each performance obligation. The estimated standalone selling prices for each Research License and
Related Services obligation was primarily based on the nature of the services to be performed and estimates of the
associated effort and costs of the services, adjusted for a reasonable profit margin what would be expected to be realized
under similar contracts. The estimated standalone selling price for the material rights was determined based on the fees
AstraZeneca would pay to exercise the license options, the estimated value of the License Option using comparable
transactions, and the probability that (i) AstraZeneca would opt into the target development, and (ii) the license options
would be exercised by AstraZeneca. Based on the relative standalone selling price, the allocation of the transaction price to
the separate performance obligations was as follows (in thousands):

The Company recognizes revenue related to amounts allocated to the Target Three Research License and Related
Services as the underlying services are performed using a proportional performance model over the period of service using
input-based measurements of total full-time equivalent effort incurred to date as a percentage of total full-time equivalent
time expected, which best reflects the progress towards satisfaction of the performance obligation. The amount allocated to
the material rights is recorded as deferred revenue and the Company commences revenue

recognition upon exercise of or upon expiry of the option. The optional future research license and the related research and 
development services related to the fourth, fifth and sixth targets reflect their standalone selling prices and do not provide 
the customer with a material right and, therefore, are not considered performance obligations and are accounted for as 
separate contracts. In June 2019, AstraZeneca selected a replacement target for the third target, and as such a new Research 
Term was started related to the Target Three Research License and Related Services. The total transaction price under the 
arrangement increased to $6.3 million for the additional research and development funding to be received. During the year 
ended December 31, 2019, the Company commenced research and development services related to the fourth and fifth 
targets. During the year ended December 31, 2020, the Company commenced research and development services related to 
the sixth target.  In October 2020, AstraZeneca terminated the collaboration activities related to the third target. As a result, 
deferred revenue related to the amount allocated to the Target 3 Material Right of $1.5 million was recognized during the 
year ended December 31, 2020. 

For the year ended December 31, 2020, 2019 and 2018, the Company recognized $2.7 million, $1.5 million, and
$0.4 million, respectively, of revenue related to the Target Three Research License and Related Service, and research and
development services for the fourth, fifth and sixth targets related to the May 2018 AstraZeneca Option Exercise. As of
December 31, 2020 and 2019, the Company recorded $3.8 million and $4.9 million, respectively, of deferred revenue in
connection with the May 2018 AstraZeneca Option Exercise and related contracts.

Oxurion Collaboration Agreement

Summary of Agreement

In August 2013, the Company entered into a Research Collaboration and License Agreement (the “Oxurion

Collaboration Agreement”) with Oxurion. Under the Oxurion Collaboration Agreement, the Company was responsible for
identifying Bicycle peptides related to the collaboration target, plasma kallikrein, for use in various ophthalmic indications. 
Oxurion is responsible for further development and product commercialization after the defined research screening is 
performed by the Company.  Under the Oxurion Collaboration Agreement, the Company granted certain worldwide 
intellectual property rights to Oxurion for the development, manufacture and commercialization of licensed compounds 
associated with plasma kallikrein.  The Company is eligible to receive up to €8.3 million upon the achievement of specified
research, development, regulatory and commercial events and research and development milestones, of which €1.8 million
has been received as of December 31, 2020. In addition, the Company is eligible to receive up to €16.5 million upon
achievement of certain regulatory milestone payments (e.g. €5 million for granting first regulatory approval in either the
United States or the European Union for the first indication). In addition, to the extent any of the collaboration products
covered by the licenses granted to Oxurion are commercialized, the Company would be entitled to receive tiered royalty
payments of mid-single digits based on a percentage of net sales.

In November 2017, the parties executed the First Deed of Amendment to the Oxurion Collaboration Agreement
(“First Amendment”), which confirmed that THR-149 was selected as a development compound. The First Amendment
provided for additional research services to be performed by the Company related to the identification of two additional
compounds for Oxurion, in its discretion, to select as development compounds. As for the work under the Oxurion
Collaboration Agreement, the Company performed work under Stage I of the research plan, which was funded at a
specified FTE rate, plus any direct out of pocket expenses, and Oxurion is responsible for Stage II research and any
development after the selection of a development compound. Additional milestones and royalties were added for the
potential additional licensed compounds, consistent with those of the initial Oxurion Collaboration Agreement. The
Company is not obligated or expected to perform any research services during Stage II of the research plan.

Either party may terminate the Oxurion Collaboration Agreement if the other party has materially breached any of

its material obligations and such breach continues after the specified cure period. Either party may terminate the Oxurion
Collaboration Agreement in the event of the commencement of any proceeding in or for bankruptcy, insolvency,
dissolution or winding up by or against the other party that is not dismissed or otherwise disposed of within a specified
time period. Oxurion may terminate the Oxurion Collaboration Agreement, entirely or on a program by program, licensed
product by licensed product or country by country basis, for convenience upon not less than 90 days prior written notice to
the Company.

Table of Contents

Accounting Analysis

Under the Oxurion Collaboration Agreement, all licenses were granted and research services to be provided by the

Company were fully completed and revenue associated with those obligations were fully recognized prior to January 1,
2016. Under the First Amendment, the Company identified a single performance obligation associated with the
performance of research services associated with Stage I of the research plan, which was recognized on a proportional
performance basis as the associated FTE efforts and costs are incurred, which best reflects the progress towards satisfaction
of the performance obligation. As of December 31, 2018, the research services under the First Amendment were complete.  
During the year ended December 31, 2018, the Company achieved a milestone related to the initiation of a Phase I clinical 
study and included $1.2 million in the transaction price, which was recognized in revenue during the year ended December 
31, 2018, as there were no remaining performance obligations.  During the year ended December 31, 2020, the Company 
achieved a milestone related to the initiation of a Phase II clinical trial and included $2.4 million in the transaction price, 
which was recognized in revenue during the year ended December 31, 2020, as there were no remaining performance 
obligations. No other unpaid development or regulatory milestones have been included in the transaction price, as all 
milestones are not considered probable at December 31, 2020 and December 31, 2019.  For the years ended December 31, 
2020, 2019 and 2018, the Company recognized $2.4 million, zero, and $1.7 million, respectively, of revenue related to its 
agreements with Oxurion. 

Evaluation and Option Agreement

On December  31, 2020 (the “Effective Date”), the Company entered into the Evaluation and Option Agreement. 

Under the terms of the Evaluation and Option Agreement, the Company agreed to transfer Bicycles (the “Option 
Materials”) to the recipient in order to evaluate a particular application of the Company’s technology platform for a period 
of up to four months (the “Evaluation Period”). The recipient agreed to pay, a non-refundable, $3.0 million option fee 
within five business days after the Effective Date.  The Evaluation Period may be extended by up to two months by written 
notice and the payment of an extension fee of $2.0 million. 

At any point during the term of the agreement and continuing through 30 days after the expiration of the
Evaluation Period, the recipient has the option to obtain an exclusive license to the Company’s intellectual property for the
purpose of continued research, development, manufacture and commercialization of products within a particular
application of the Company’s platform technology. The recipient may terminate the agreement for convenience upon
30 days written notice to the Company. The upfront payment of $3.0 million and extension payment of $2.0 million are
fully creditable against any upfront payment to be paid upon the execution of a license agreement.

For the year ended December 31, 2020, the Company recognized zero revenue and $3.0 million of deferred
revenue related to the Evaluation and Option Agreement. The Company concluded that the transaction price is $3.0
million, and all other amounts are excluded from the transaction price as they relate to fees that can only be achieved
subsequent to the exercise of an option. The transaction price was allocated to the single performance obligation, an option
to enter into a future license agreement which is a material right, as the Evaluation and Option Agreement payment is
creditable against the upfront payments to paid for a license agreement. The Company will begin to recognize revenue
when the option is exercised or when the option expires.

Material Transfer Agreement

In October 2018, the Company entered into a Materials Transfer Agreement. Under the terms of the agreement,
the Company agreed to transfer bicyclic peptides (the “Materials”) to the recipient for the purpose of testing the materials
in order to evaluate the Company’s technology platform. The recipient agreed to pay the Company $1.0 million within 30
business days after receipt of the materials and related data package, which was paid to the Company in May 2019. For the
years ended December 31, 2020 and 2019, the Company recognized zero and $1.0 million, respectively, of revenue related
to its Materials Transfer Agreement, as the Company concluded that the recipient has the ability to direct the use of and
obtain substantially all of the remaining benefit from the Materials upon the delivery of the Materials and the data package.

On December 13, 2016, the Company entered into a Clinical Trial and License Agreement with Cancer Research

Technology Limited (“CRTL”), a wholly owned subsidiary of Cancer Research UK that Cancer Research UK’s
commercial activities operate through, and Cancer Research UK (the “Cancer Research UK Agreement”). Pursuant to the
Cancer Research UK Agreement, as amended in March 2017 and June 2018, Cancer Research UK’s Centre for Drug
Development will sponsor and fund a Phase Ia and Phase IIa clinical trial for the Company’s lead product candidate,
BT1718, a Bicycle Toxin Conjugate, in patients with advanced solid tumors.

Cancer Research UK is responsible for designing, preparing, carrying out and sponsoring the clinical trial at its
cost. The Company is responsible for supplying agreed quantities of GMP materials for the trial, the supply of which has
been completed. In the event that additional quantities are needed, the Company will provide Cancer Research UK with all
reasonable assistance to complete the arrangements necessary for the generation and supply of such additional GMP
materials, but Cancer Research UK will be responsible for supplying and paying for such additional quantities of GMP
materials.

The Company granted Cancer Research UK a license to its intellectual property in order to design, prepare for,

sponsor, and carry out the clinical trial. The Company retains the right to continue the development of BT1718 during the
clinical trial. Upon the completion of the Phase I/IIa clinical trial, the Company has the right to obtain a license to the
results of the clinical trial upon the payment of a milestone, in cash and ordinary shares, with a combined value in the mid
six digit dollar amount. If such license is not acquired, or if it is acquired and the license is terminated and the Company
decides to abandon development of all products that deliver cytotoxic payloads to the MT1 target antigen, the Company
will assign or grant to CRTL an exclusive license to develop and commercialize the product on a revenue sharing basis (in
which case the Company will receive tiered royalties of 70% to 90% of the net revenue depending on the stage of
development when the license is granted). The Cancer Research UK Agreement contains additional future milestone
payments upon the achievement of development and regulatory milestones, payable in cash and shares, with an aggregate
total value of $50.9 million, as well as royalty payments based on a single digit percentage on net sales of products
developed.

The Cancer Research UK Agreement can be terminated by either party upon an insolvency event, material breach
of the terms of the contract, or upon a change in control (and the new controlling entity generates its revenue from the sale
of tobacco products or is an affiliate of such party). Cancer Research UK may terminate the arrangement for safety reasons
or if it determines that the objectives of the clinical trial will not be met, in which case, if the trial is terminated by Cancer
Research UK prior to the completion of the Phase 1a dose escalation portion of the trial for such reasons or if Cancer
Research UK refuses release of any additional quantities of GMP materials or if the parties cannot agree upon a plan to
supply the additional quantities of GMP materials, the Company will be obligated to refund fifty percent of the costs and
expenses incurred or committed by Cancer Research UK to perform the clinical trial. If the trial is terminated by Cancer
Research UK for an insolvency event, a material breach by the Company, or if the Company is acquired by an entity that
generates its revenue from the sale of tobacco products or is an affiliate of such party, the Company will reimburse Cancer
Research UK in full for all costs paid or committed in connection with the clinical trial and no further license payments,
where applicable, shall be due. In such case where the Company is acquired by an

F-36

 
    
    
    
 
  
  
  
Table of Contents

entity that generates its revenue from the sale of tobacco products or is an affiliate of such party, Cancer Research UK will
not be obliged to grant a license to the Company in respect of the results of the clinical trial and the Company will assign or
grant to CRTL an exclusive license to develop and commercialize the product without CRTL being required to make any
payment to the Company.

The Company concluded that the costs incurred by Cancer Research UK is a liability in accordance with
ASC 730, Research and Development, as certain payments are not based solely on the results of the research and
development having future economic benefit. As such, for the year ended December 31, 2020 and 2019, the Company
recorded a liability of $2.6 million and $2.0 million, respectively, which is recorded in other long-term liabilities in the
consolidated balance sheets. The liability is recorded as incremental research and development expense in the consolidated
statements of operations and comprehensive loss.

BT7401

 In December 2019, the Company entered into a clinical trial and license agreement with Cancer Research 
Technology Limited and Cancer Research UK. Pursuant to the agreement, Cancer Research UK’s Centre for Drug 
Development will fund and sponsor development of BT7401, a multivalent Bicycle CD137 agonist, from current
preclinical studies through the completion of a Phase IIa trial in patients with advanced solid tumors.

The Company granted to Cancer Research UK a license to the Company’s intellectual property in order to design,
prepare for, sponsor, and carry out the clinical trial and all necessary preclinical activities to support the trial. The Company
retains the right to continue the development of BT7401 during the clinical trial. Upon the completion of the Phase I/IIa
clinical trial, the Company has the right to obtain a license to the results of the clinical trial upon the payment of a
milestone, in cash and ordinary shares, with a combined value in the mid six digit dollar amount. If such license is not
acquired, or if it is acquired and the license is terminated and the Company decides to abandon development of all products
that contain BT7401 or all the pharmaceutically active parts of BT7401, CRTL may elect to receive an exclusive license to
develop and commercialize the product on a revenue sharing basis (in which case the Company will receive tiered royalties
of 55% to 80% of the net revenue depending on the stage of development when the license is granted) less certain costs, as
defined by the agreement. The BT7401 Cancer Research UK agreement contains additional future milestone payments
upon the achievement of development, regulatory and commercial milestones, payable in cash, with an aggregate total
value of up to $60.3 million for each licensed product, as well as royalty payments based on a single digit percentage on
net sales of products developed, and sublicense royalties to the Cancer Research UK in the low double digit percentage of
sublicense income depending on the stage of development when the license is granted.

The BT7401 Cancer Research UK agreement can be terminated by either party upon an insolvency event, material

breach of the terms of the contract, or upon a change in control (and the new controlling entity generates its revenue from
the sale of tobacco products), or upon written notice by either party prior to the last cycle of treatment has been completed
under the clinical trial. If the trial is terminated by the Company prior to the filing of a clinical trial authorization, or by
Cancer Research UK for an insolvency event or a material breach by the Company prior to the start of a clinical trial, the
Company will reimburse Cancer Research UK for certain costs paid or committed prior to the start of the clinical trial. In
such case where the Company is acquired by an entity that generates its revenue from the sale of tobacco products, Cancer
Research UK will not be obliged to grant a license to us in respect of the results of the clinical trial and CRTL may elect to
receive an exclusive license to develop and commercialize the product without CRTL being required to make any payment
to the Company. The Company concluded that the BT7401 Cancer Research UK arrangement does not represent a liability
in accordance with ASC 730, Research and Development, as the payments are based solely on the results of the research
and development having future economic benefit and risk of repayment is substantive and genuine, and as such there was
no accounting impact as of and for the year ended December 31, 2020.

During the years ended December 31, 2020, 2019 and 2018, the Company recorded an income tax benefit of $0.7 

million, $0.3 million and $0.4 million, respectively. The Company is subject to United Kingdom corporate taxation.  Due 
to the nature of its business, the Company has generated losses since inception and therefore not paid United Kingdom 
corporation tax.  The Company's income tax benefit is mainly the result of deferred tax assets benefited in the United States 
that do not have a valuation allowance against them because of profits that will be generated by an intercompany service 
agreement.

The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realization of deferred 
tax assets requires significant judgment. In determining whether its deferred tax assets are more likely than not realizable, 
the Company evaluated all available positive and negative evidence, and weighed the evidence based on its objectivity. 
After consideration of the evidence, including the Company's history of cumulative net losses in the U.K., and has 
concluded that it is more likely than not that the Company will not realize the benefits of its U.K. deferred tax assets and 
accordingly the Company has provided a valuation allowance for the full amount of the net deferred tax assets in the U.K. 
The Company has considered the Company's history of cumulative net profits in the United states, estimated future taxable 
income and concluded that it is more likely than not that the Company will realize the benefits of its United State deferred 
tax assets and has not provided a valuation allowance against the net deferred tax assets in the United States.  The valuation 
allowance increased in the year ended December 31, 2020 by $8.0 million due to the corresponding increase in UK 
deferred tax assets, primarily due to operating loss carryforwards generated during the year that were not surrendered for 
research credit utilization.

The Company recorded a valuation allowance against all of its U.K. deferred tax assets as of December 31, 2020

and 2019.

The Company intends to continue to maintain a full valuation allowance on its U.K. deferred tax assets until there

is sufficient evidence to support the reversal of all or some portion of these allowances. The release of the valuation
allowance would result in the recognition of certain deferred tax assets and an increase to the benefit for income taxes for
the period the release is recorded. However, the exact timing and amount of the valuation allowance release are subject to
change on the basis of the level of profitability that the Company is able to actually achieve.

The benefit for income taxes shown on the consolidated statements of operations differs from amounts that would

result from applying the statutory tax rates to income before taxes primarily because of certain permanent expenses that
were not deductible, U.K., federal and state research and development credits, as well as the application of valuation
allowances against the U.K. deferred tax assets.

Table of Contents

As of December 31, 2020, the Company had $72.0 million of U.K. operating loss carryforwards and $0 of U.S. 

federal and state net operating loss carryforwards.  The U.K. operating loss carryforwards have an indefinite life. As of 
December 31, 2020, the Company had $0.8 million and $0.4 million of federal and state research and development credit 
carryforwards, respectively, that expire at various dates through 2040.

The Company recognizes, in its consolidated financial statements, the effect of a tax position when it is more

likely than not, based on the technical merits, that the position will be sustained upon examination. The Company had no
uncertain tax positions during the years ended of December 31, 2020 and 2019. There are no amounts of interest or
penalties recognized in the consolidated statements of operations or accrued on the consolidated balance sheet for any
period presented. The Company does not expect any material changes in these uncertain tax benefits within the next 12
months.

The Company files income tax returns in the United Kingdom, and in the United States for federal income taxes

and in the Commonwealth of Massachusetts for state income taxes. In the normal course of business, the Company is
subject to examination by tax authorities in these jurisdictions. The 2019 and 2018 tax year remains open to examination
the by HM Revenue & Customs. The statute of limitations for assessment with the Internal Revenue Service is generally
three years from filing the tax return. As such, all years since 2017 in the U.S. remain open to examination. The Company
is currently not under examination by jurisdictions for any tax years.

13. Commitments and Contingencies

Leases

In September 2017, Bicycle Therapeutics Inc. entered into a lease agreement for office and laboratory space in

Lexington, Massachusetts, which commenced on January 1, 2018 and expires on December 31, 2022. Bicycle Therapeutics
Inc. has the option to extend for a successive period which is not included in the lease term as it is not reasonably certain
that the option will be exercised. In conjunction with the lease agreement, Bicycle Therapeutics Inc. paid a security deposit
of $0.2 million as well as prepaid rent of $0.1 million for the first month of the third, fourth, and fifth year of the lease. The
deposit is recorded in other assets in the consolidated balance sheets. The Company has recorded a right‑of‑use asset
(inclusive of the impact of prepaid rent) and corresponding lease liability, by calculating the present value of lease
payments, discounted at 9%, the incremental borrowing rate, over the lease term.

In October 2017, the Company entered into a lease agreement for office and laboratory space in Building 900,
Babraham Research Campus, Cambridge, U.K., which expires on December 21, 2021. The annual rent is approximately
$0.5 million. The Company has the right to renew the lease for five years commencing December 21, 2021, which is not
included in the lease term as it is not reasonably certain that the right will be exercised. Service charges are also payable
based on floor area and are estimated to be approximately $0.1 million per year. In conjunction with the 2017 lease
agreement, the Company paid a security deposit of $0.6 million, which is recorded in other assets in the consolidated
balance sheets. The Company has recorded a right-of-use asset and corresponding lease liability, by calculating the present
value of lease payments, discounted at 7.75%, the incremental borrowing rate, over the lease term.

The Company identified and assessed the following significant assumptions in recognizing the right‑of‑use assets

and corresponding lease liabilities:

● Expected lease term — The expected lease term includes both contractual lease periods and, when applicable,
cancelable option periods when it is reasonably certain that the Company would exercise such options. The
Company has not included any option periods in the expected lease term as it is not reasonably certain that
the Company will exercise such options.

● Incremental borrowing rate — The Company’s lease agreements do not provide an implicit rate. As the

Company does not have any external borrowings for comparable terms of its leases, the Company estimated
the incremental borrowing rate by comparing interest rates available in the market for similar borrowings and
third‑party quotations.

F-40

Table of Contents

● Lease and non‑lease components — In certain cases, the Company is also responsible for certain additional
charges for operating costs, including insurance, maintenance, taxes, and other costs incurred, which are
billed based on both usage and as a percentage of the Company’s share of total square footage. The amounts
paid are considered non‑lease components. The Company has elected the practical expedient which allows
the non‑lease components to be combined with the lease components. The payments for other operating costs
are considered variable lease cost and are recognized in the period in which the costs are incurred.

The components of the Company’s lease expense, which are recorded as a component of research and
development expenses and general and administrative expenses in the consolidated statement of operations and
comprehensive loss are as follows (in thousands):

Operating lease cost
Variable lease cost

Also, as previously disclosed in the Company's 2019 Annual Report on Form 10-K and under the previous lease

accounting standard, ASC 840, Leases, the Company recorded rent expense of $1.0 million during the year ended
December 31, 2018.

Future minimum lease payments under non-cancelable operating leases under ASC 842 as of December 31, 2020

are as follows (in thousands):

The Company has entered into various agreements with contract manufacturing organizations to provide clinical

trial materials and with vendors for preclinical research studies, synthetic chemistry and other services for operating
purposes. These payments are not included in the table of operating lease payments above since the contracts are generally
cancelable at any time upon less than 90 days’ prior written notice. The Company is not contractually able to terminate for
convenience and avoid any and all future obligations to these vendors. Under such agreements, the Company is
contractually obligated to make certain minimum payments to the vendors, with the payments in the event of a termination
with less than 90 days’ notice based on the timing of the termination and the exact terms of the agreement.

Legal proceedings

From time to time, the Company or its subsidiaries may become involved in various legal proceedings and claims,

either asserted or unasserted, which arise in the ordinary course of business.

In September 2016, the Company’s subsidiary, BicycleRD, filed a complaint in the District Court of the Hague
against Pepscan Systems B.V. and its affiliates (“Pepscan”) to contest the right of Pepscan to terminate a non-exclusive
patent license agreement entered into with Pepscan in 2009 (“PLA”). On November 20, 2020, the Company entered into a
settlement and license agreement with Pepscan regarding Bicycle’s use of Pepscan’s CLIPS peptide technology. The

F-41

    
    
 
 
 
 
 
 
    
 
 
 
 
 
Table of Contents

companies agreed to settle all intellectual property disputes worldwide. Under the terms of the settlement, Bicycle has been
granted a license to use CLIPS peptide technology in the development of its product candidates BT1718 and THR-149.
Bicycle paid €3 million in November 2020, will pay €1 million on the first anniversary of the date of settlement, and will
make additional future milestone payments upon the achievement of development, regulatory and commercial milestones,
with an aggregate total value of $92.4 million. The Company recorded $4.7 million of expense related to the settlement and
license agreement with Pepscan during the year ended December 31, 2020, and a liability of $1.2 million related to the
Pepscan litigation as of December 31, 2020, which is included in current liabilities in the consolidated balance sheet.

Founder Royalty arrangements

At the time BicycleRD Limited was organized, BicycleRD Limited entered into a royalty agreement with its

founders and initial investors (the “Founder Royalty Agreement”). Pursuant to the Founder Royalty Agreement, as
amended, the Company will pay a royalty rate in the low single digit percentages on net product sales under the
collaborations with Oxurion and AstraZeneca to its founders and initial investors, for a period of 10 years from the first
commercial sale on a country by country basis. No royalties have been earned or paid under the royalty arrangements to
date.

Indemnification obligations

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to
vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses
arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In
addition, the Company has indemnification obligations towards members of its board of directors and officers that will
require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their
status or service as directors or officers. The maximum potential amount of future payments the Company could be
required to make under these indemnification arrangements is, in many cases, unlimited. To date, the Company has not
incurred any material costs as a result of such indemnification obligations. The Company is not aware of any claims under
indemnification arrangements, and therefore it has not accrued any liabilities related to such obligations in its consolidated
financial statements as of December 31, 2020 and 2019.

shares, and which prior to the completion of the IPO, included convertible preferred shares, warrants to subscribe for
Series A and Series B1 Preferred Shares, and unvested restricted shares, have been excluded from the computation of
diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of
ordinary shares outstanding used to calculate both basic and diluted net loss per share attributable to ordinary shareholders
is the same. The Company excluded the following potentially dilutive ordinary shares, presented based on

compensation on a pre-tax basis. Matching contributions to the 401(k) Plan may be made at the discretion of the
Company’s board of directors. During the years ended December 31, 2020, 2019, and 2018 the Company made
contributions totaling $0.2 million, $0.2 million and $0.1 million, respectively, to the 401(k) Plan.

provisions of any restrictive covenants or confidentiality obligations arising out of any employment
with any other employer or former employer.

You warrant that you have the right to work in the United Kingdom and you agree to provide to the

time  during  the  course  of  this  Agreement  you  cease  to  have  the  right  to  work  in  the  United

compensation.

 You  may  also  be  required  to  carry  out  such  additional  or  alternative  tasks  as  may  from  time  to
time be reasonably required of you consistent with your executive level and job title, provided that

time  and  exclusively  devote  the  whole  of  your  working  time,  skills,  ability  and  attention  to  the

REMUNERATION

Your salary will be USD420,000 per annum paid monthly in arrears on or about the last working
day  of  each  month  (less  statutory  and  voluntary  deductions)  (“Salary”).  Your  Salary  will  be
converted to GBP and paid in GBP based on the trailing twelve-month average of the USD/GBP
Bank of England daily spot exchange rate applicable on the Effective Date, with the exchange rate
being  revised  according  to  the  trailing  twelve-month  average  of  the  USD/GBP  Bank  of  England
daily spot exchange rate as of 1 January of each year.  Your Salary will be reviewed annually in
accordance with the Company’s practices from time to time (which is expected to be by the end of
the  first  quarter  of  each  year).  You  will  be  notified  in  writing  of  any  changes  to  your  Salary  or
benefits.

You agree that the Company may deduct from the Salary or any other sum due to you (including
any  pay  in  lieu  of  notice)  any  amounts  due  to  the  Company  including,  without  limitation,  any
overpayment of salary, loan or advance.

For the purposes of this Agreement your earned salary shall mean the proportion of your Salary
earned  by  and  due  to  you  in  each  calendar  year  of  employment  with  the  Company  (“Earned
Salary”).

4.4

Annual Performance Bonuses:

You will be eligible to participate in the Company's discretionary annual performance related bonus
scheme to a maximum value of 40% of your Earned Salary in relation to your performance against
agreed  annual  corporate  and  personal  performance  objectives  as  set  out  below  (the  “Annual
Performance Bonus”). That is, if the compensation committee (the “Compensation Committee”)
of the board of directors (the “Board”) of the Company’s parent company, Bicycle Therapeutics plc
(“BTL”)  determines  that  you  have  completed  all  such  corporate  and  personal  objectives  to  its
satisfaction in a given year, your bonus would be 40% of your Earned Salary in that year, excluding
any other bonuses in this offer. Such bonus may be payable in cash or, in whole or in part, in share
options in BTL, as agreed by you and the Compensation Committee following notification by you of
your  preference  at  least  90  days  prior  to  the  normal  payment  date  (and  in  the  case  of  share
options  with  the  appropriate  HMRC  valuation  process  (if  required  by  the  Compensation
Committee) and Board approval so as to be compliant with BTL’s share option plan rules), with due
consideration for the operational requirements of the Company at that time in your role as CMO.

Any  Annual  Performance  Bonus  paid  will  not  be  pensionable  and  are  subject  to  statutory
applicable  tax  and  National  Insurance  deductions.  Performance  will  be  assessed  by  the
Compensation  Committee  at  the  end  of  each  calendar  year,  against  annual  corporate  and
personal performance objectives agreed between you and the Board at the start of each calendar
year, with any such bonus being payable in the first quarter of the following year. Qualification for
your Annual Performance Bonus will require that you are employed by the Company (and have not
served notice of termination of your employment to the Company) on

2

31 December of the year to which your bonus entitlement applies.

4.5

Equity Incentives

BTL has established the Bicycle Therapeutics Plc 2020 Equity Incentive Plan (the “EIP”).

On or as soon as practicable following the Effective Date, it is intended that you will be granted an
option under the EIP to acquire 120,000 ordinary shares in the capital of BTL (“Shares”).

Any  options  granted  under  this  paragraph  4.5  shall  be  subject  to  (i)  the  approval  of  the
Compensation  Committee;  (ii)  the  rules  of  the  EIP  (as  amended  from  time  to  time);  and  (iii)  the
terms of the option grant documentation which will be provided to you following such grant.

BENEFITS

The Company operates a group personal pension scheme. You will be automatically enrolled into
the pension scheme upon joining the company, subject to satisfying certain eligibility criteria and
the rules of the scheme as amended from time to time. The Company will contribute an amount
equal to 12% of your basic annual salary to the Scheme each year, payable monthly and subject
to  the  rules  of  the  Scheme  and  the  tax  reliefs  and  exemptions  available  from  HM  Revenue  &
Customs,  as  amended  from  time  to  time.  You  may  choose  to  make  additional  personal
contributions into the pension scheme. You may opt out of the Pension Scheme by requesting this
in writing. A contracting-out certificate is not in force in respect of your employment.

The  Company  currently  operates  a  private  healthcare  scheme  and  subject  to  acceptance  by  the
insurer on reasonable terms, you will be entitled to join.

The  Company  operates  a  death  in  service  scheme  to  the  level  of  four  times  your  annual  salary,
which you automatically join upon commencement of employment.

Further details regarding benefits will be provided upon commencement of your employment. The
Company reserves the right to replace or supplement any or all of the scheme(s) referred to in this
paragraph  5,  or  to  amend  them  at  any  time  without  compensation,  provided  that  equivalent
scheme(s) providing a similar level of benefit are put in place.

6

EXPENSES

The Company shall reimburse all reasonable out of pocket expenses properly incurred by you in
the  performance  of  the  duties  under  this  Agreement  including  travelling,  subsistence  and
entertainment expenses provided you follow the Company’s guidelines/allowances in force at the
relevant time and provided that you shall, where reasonably practicable, provide the Company with
vouchers,  invoices  or  such  other  evidence  of  such  expenses  as  the  Company  may  reasonably
require.

7

7.1

HOURS OF WORK

Your normal working hours are Monday to Friday from 9.00 am to 5.30 pm on each working day
with  one  hour  for  lunch.    You  will  be  required  to  work  such  other  hours  as  shall  be  reasonably
necessary for you to perform your duties for which no further remuneration is

payable.

By  entering  into  this  Agreement  you  confirm,  that  in  your  capacity  as  CMO  you  may  choose  or
determine  the  duration  of  your  working  time  and  the  working  time  limits  set  out  in  part  II  of  the
Working Time Regulations 1998 do not apply to you.

HOLIDAYS

In addition to the usual public holidays you will be entitled to 25 working days paid holiday in each
calendar year. The holiday will accrue on a pro rata basis throughout each calendar year.

Holidays may only be taken at such time or times as are approved beforehand by the CEO, such
approval  not  to  be  unreasonably  withheld  or  delayed.    You  must  give  reasonable  notice  of
proposed holiday dates and use the HR system for approval.

The holiday year runs from January to December. With the agreement of the CEO, you may carry
forward up to 5 days of untaken holiday into the next holiday year.  Any carried over holiday must
be taken by the end of March of the following calendar year or will be forfeited and no payment will
be made in respect of any days so forfeited.  You will not generally be permitted to take more than
10 days holiday at any one time.

Upon termination of your employment you will receive pay in lieu of accrued but untaken holiday.
 The Company may deduct an appropriate sum in respect of days taken in excess of your pro rata
entitlement from your final remuneration on the basis that one day’s holiday will be calculated as
1/260ths of your basic annual salary.

In the event that notice of termination of this Agreement is served by either party, the Company
may require you to take any outstanding holiday during this notice period.

SICKNESS AND OTHER ABSENCE

If you are unable to attend at work by reason of sickness or injury or any unauthorised reason you
must inform the Company as soon as possible on the first day of absence (and in any event not
later than 11.00 am on the first day of absence) and, in the case of absence of uncertain duration,
you must keep the Company regularly informed of your continued absence and your likely date of
return.    You  are  expected  to  observe  this  rule  very  strictly  since  failure  to  do  so  will  entitle  the
Company to stop payment in respect of each day you fail to notify the Company.

If your absence, due to sickness or injury, is for less than seven (7) days, on your return to work
you  are  required  to  immediately  self-certificate  on  the  HR  system.  If  your  absence  continues  for
more  than  seven  (7)  consecutive  days  (whether  or  not  working  days)  you  must  provide  the
Company  with  a  doctor's  certificate  from  the  seventh  consecutive  day  of  sickness  or  injury.  This
doctor’s certificate must be provided to the Company promptly following the seventh consecutive
day of absence. If illness continues after the expiry of the first certificate, further certificates must
be provided promptly to cover the whole period of absence.

Subject to your compliance with the Company’s sickness absence procedures (as amended from
time to time), the Company may in its sole and absolute discretion pay full salary and contractual
benefits during any period of absence due to sickness or injury for up to an aggregate of 3 months
in any fifty-two (52) week period (whether such absence is continuous

4

or intermittent in any calendar year). Such payment shall be inclusive of any statutory sick pay due
in accordance with applicable legislation in force at the time of absence.  The Company may, in its
sole  and  absolute  discretion,  extend  the  period  of  allowance  in  an  individual  case  if  the
circumstances  so  justify.    Thereafter,  the  Company  shall  pay  statutory  sick  pay  or  equivalent
benefit to which you may be entitled subject to your compliance with the appropriate rules.

Whether  absent  from  work  or  not,  you  may  be,  but  only  on  reasonable  grounds,  required  to
undergo a medical examination by a Company doctor and your consent will be sought for a report
to be sent to the Company.

The  payment  of  sick  pay  in  accordance  with  this  paragraph  9  is  without  prejudice  to  the
Company’s right to terminate this Agreement prior to the expiry of your right to payments.

In the event you are incapable of performing your duties by reason of injuries sustained wholly or
partly as a result of a third party's actions all payments made to you by the Company as salary or
sick pay shall to the extent that compensation is recoverable from that third party constitute loans
to you and shall be due and owing when and to the extent that you recover compensation for loss
of earnings from the third party.

GARDEN LEAVE

After  notice  of  termination  has  been  given  by  you  or  the  Company,  the  Company  may  at  its

to remain away from the Company’s business premises and those of any Group Company
(unless given written permission to do otherwise);

not to contact any of the Company’s clients, suppliers or employees or those of any Group
Company without the Company’s prior written permission;

to carry out only part of your duties, or to carry out alternative duties or special projects for
the Company within your skill set;

to co-operate in the handover of your duties and responsibilities;

to  resign  from  any  offices  (including  as  a  director)  you  hold  within  the  Company  or  any
Group Company or by virtue of your employment with us;

to answer, in an honest and helpful way, such questions as the Company may reasonably
ask of you;

to  keep  the  Company  informed  of  your  whereabouts  and  contact  details  and  to  remain
reasonably contactable and available for work.

10.2

During  any  such  period  as  described  in  paragraph  10.1  (“Garden  Leave”)  the  Company  may
appoint another person to carry out some or all of your duties. You will continue to owe all other
duties and obligations (whether express or implied including fidelity and good faith) during Garden
Leave and you shall continue to receive full pay and benefits (except that you will not

5

10.3

10.4

10.5

accrue  any  further  entitlement  to  any  cash  or  equity  incentive  awards  or  bonus  payments  in
respect of the Garden Leave period).

By  placing  you  on  Garden  Leave,  the  Company  will  not  be  in  breach  of  this  Agreement  or  any
implied duty of any kind whatsoever nor will you have any claim against the Company in respect of
any such action.

During any period of Garden Leave you will remain readily contactable and available for work save
when on paid holiday taken in accordance with paragraph 8. In the event that you are not available
for  work  having  been  requested  by  the  Company  to  do  so,  you  will,  notwithstanding  any  other
provision of this Agreement, forfeit any right to salary and contractual benefits.

During any period of Garden Leave the Company may require you to deliver up any Confidential
Information or property of the Company or any Group Company and upon instruction, delete any
emails, spreadsheets or other Confidential Information and you will confirm your compliance with
this paragraph 10.5 in writing if requested to do so by the Company.

10.6

During any period of Garden Leave the Company may require you to take any outstanding holiday
entitlement.

11

NOTICE

11.1 Without prejudice to the Company’s right to summarily terminate your employment in accordance
with  paragraph  11.3  below  and  your  right  to  summarily  terminate  your  employment  for  Good
Reason in accordance with paragraph 11.4 below, either you or the Company may terminate your
employment by giving to the other not less than:

(a)

(b)

month’s notice in writing; and

following successful completion of the Probationary Period, six months’ notice in writing.

11.2

The  Company  reserves  the  right  in  its  sole  and  absolute  discretion  to  give  written  notice  to
terminate  your  employment  forthwith  and  to  make  a  payment  to  you  in  lieu  of  salary  and  the
benefits  set  out  in  paragraph  5  of  this  Agreement  for  all  or  any  unexpired  part  of  the  applicable
notice  period.  For  the  avoidance  of  doubt,  any  payment  in  lieu  made  pursuant  to  this  paragraph
11.2  will  not  include  any  element  in  relation  to  any  payment  in  respect  of  (i)  any  Annual
Performance  Bonus  or  (ii)  any  holiday  entitlement  that  would  have  otherwise  accrued  during  the
period for which the payment in lieu is made.  For the further avoidance of doubt, if the Company
elects to make a Payment in Lieu after notice of termination has been given by you, this will not
constitute a termination by the Company without Cause for the purposes of paragraphs 11.7 and
11.8 below.  

11.3

The  Company  may  summarily  terminate  your  employment  hereunder  (without  notice)  for  Cause.
 For purposes of this Agreement, “Cause” shall mean where you:

being  under  the  influence  of  alcohol  or  drugs  at  work,  causing  actual  or  threatening

Agreement,  or  materially  fail  to  observe  the  lawful  directions  of  the  Company,  or  breach

Company’s policy from time to time on matters relating to harassment;

in the United Kingdom or elsewhere for which a non-custodial sentence is imposed);

disrepute  or  otherwise  prejudices  or  is  in  the  reasonable  opinion  of  the  Company
considered likely to prejudice the reputation of the Company;

in  the  reasonable  opinion  of  the  Company,  are  guilty  of  any  serious  negligence  in
connection with or affecting the business or affairs of the Company;

aggregate period of 26 weeks in any fifty-two (52) week period even if, as a result of such
termination,  you  would  or  might  forfeit  any  entitlement  to  benefit  from  sick  pay  under
paragraph 9.3 above.

Any delay or forbearance by the Company in exercising any right of termination in accordance with
this paragraph 11.3 will not constitute a waiver of such right.

You  may  summarily  terminate  your  employment  hereunder  at  any  time  (without  notice)  for  Good
Reason after complying with the Good Reason Process.  For purposes of this Agreement, “Good
Reason” shall mean that you have complied with the “Good Reason Process” (hereinafter defined)
following  the  occurrence  of  any  of  the  following  events:  (i)  a  material  diminution  in  your
responsibilities, authority or duties; (ii) a material diminution in your Salary; (iii) a material change
in  the  geographic  location  at  which  you  provides  services  to  the  Company;  or  (iv)  the  material
breach  of  this  Agreement  by  the  Company.    “Good  Reason  Process”  shall  mean  that  (i)  you
reasonably determine in good faith that a “Good Reason” condition has occurred; (ii) you notify the
Company in writing of the first occurrence of the Good Reason condition within 60 days of the first
occurrence  of  such  condition;  (iii)  you  cooperate  in  good  faith  with  the  Company’s  efforts,  for  a
period not less than 30 days following such notice (the “Cure Period”), to remedy the condition;
(iv)  notwithstanding  such  efforts,  the  Good  Reason  condition  continues  to  exist;  and  (v)  you
terminate your employment (without notice) within 60 days after the end of the Cure Period.  If the
Company  cures  the  Good  Reason  condition  during  the  Cure  Period,  Good  Reason  shall  be
deemed not to have occurred.

Your employment hereunder shall also terminate immediately upon your death.

If  your  employment  with  the  Company  is  terminated  for  any  reason,  the  Company  shall  pay  or
provide  to  you  (or  to  your  authorised  representative  or  estate)  (i)  any  Salary  earned  through  the
Termination  Date  (as  defined  below);  (ii)  unpaid  expense  reimbursements  (subject  to,  and  in
accordance  with,  paragraph  6  of  this  Agreement);  and  (iii)  any  vested  benefits  you  may  have
under  any  employee  benefit  plan  of  the  Company  through  the  Termination  Date,  which  vested
benefits  shall  be  paid  and/or  provided  in  accordance  with  the  terms  of  such  employee  benefit
plans (collectively, the “Accrued Benefits”).

(being for any reason not covered by paragraph 11.3), or you terminate your employment for Good
Reason  (as  provided  in  paragraph  11.4),  in  either  case  outside  of  the  Change  in  Control  Period

The  provisions  of  this  paragraph  11.8  shall  apply  in  lieu  of,  and  expressly  supersede,  the
provisions  of  paragraph  11.7  regarding  severance  pay  and  benefits  upon  a  termination  by  the
Company  without  Cause  or  by  you  for  Good  Reason  if  such  termination  of  employment  occurs
within  12  months  after  the  occurrence  of  the  first  event  constituting  a  Change  in  Control  (such
period,  the  “Change  in  Control  Period”)  and  provided  you  have  successfully  completed  the
Probationary Period. These provisions shall terminate and be of no further force or effect after the
Change in Control Period.

reason  not  covered  by  paragraph  11.3)  or  you  terminate  your  employment  for  Good

DATA PROTECTION

Processing of personal data and our policies

15

Information  relating  to  an  individual  (or  from  which  an  individual  may  be  identified)  is  called

18.1
“personal data”.

In processing personal data, we are required to comply with the law on data protection. To help us
18.2
achieve this, we have produced a privacy notice (“Privacy Notice”).  This may be found in the Employee
Handbook.  You must read this and comply with it in carrying out your work.  

Data protection principles

In complying with the law on data protection, we are required to comply with what are known as
18.3
data  protection  principles.    These  are  summarised  in  our  Privacy  Notice.    In  performing  your  role  and
carrying out your responsibilities, you must do your best to ensure that we comply with these principles.

A  key  element  of  the  data  protection  principles  is  the  duty  to  ensure  that  data  is  processed
18.4
securely  and  protected  against  unauthorised  or  unlawful  processing  or  loss.    Key  elements  include  the
following:

(a)

(b)

(c)

You must ensure that laptops, memory sticks, phones and other mobile devices are 
password protected and encrypted.  You must not take such devices outside the office 
without encryption.  You must take care of them and keep them secure. 

You must use strong passwords, changing them when asked and not sharing them with
unauthorised colleagues.

You must not access other individuals’ personal data unless in the course of your work.

Data breach – and urgent notification

If you discover a data breach, you must notify the CFO or CFO (copied to the CEO) immediately –
18.5
and,  if  practicable,  within  one  hour.    Depending  on  context,  you  may  then  need  to  provide  further
information on the circumstances of the breach.

A data breach occurs where there is destruction, loss, alteration or unauthorised disclosure of or
18.6
access to personal data which is being held, stored, transmitted or processed in any way.  For example,
there is a data breach if our servers are hacked or if you lose a laptop or USB stick or send an email to the
wrong person by mistake.

Failure to notify a breach or to provide information as set out above will be treated seriously and

18.7
disciplinary action may be taken.

Why we process personal data

For  information  on  the  nature  of  the  data  we  process,  why  we  process  it,  the  legal  basis  for

18.8
processing and related matters, please refer to our Privacy Notice.  In summary:

(a)

(b)

We process personal data relating to you for the purposes of our business including 
management, administrative, employment and legal purposes.  

We monitor our premises and the use of our communication facilities, including using
CCTV cameras, monitoring compliance with our data and IT policies, and where non-

16

compliance is suspected, looking in a more targeted way.

The summary above is for information only.  We do not, in general, rely on your consent as a legal
18.9
basis for processing.  Agreeing the terms of this Agreement will not constitute your giving consent to our
processing of your data.  

18.10 We reserve the right to amend the documents referred to above from time to time.

Exhibit 10.18

BICYCLE THERAPEUTICS PLC
NON-EMPLOYEE DIRECTOR COMPENSATION POLICY
AS AMENDED THROUGH DECEMBER 16, 2020

This Non-Employee Director Compensation Policy (the “Policy”) has been established in order to
attract and retain non-employee directors who have the knowledge, skills and experience to serve
as a member of the Board of Directors (the “Board”) of Bicycle Therapeutics plc (the “Company”).
 Directors who are employees of the Company or any of its subsidiaries will receive no additional
compensation for their service as directors.  

All  equity  awards  granted  in  accordance  with  this  Policy  shall  be  granted  under  the  Company’s
then-current equity incentive plan (or director equity incentive plan, if any).

A. EQUITY AWARDS

At  the  next  scheduled  meeting  of  the  Board  or  the  Compensation  Committee,  as  applicable,
following  a  non-employee  director’s  initial  election  to  the  Company’s  Board,  the  Board  or  the
Compensation  Committee  of  the  Board  shall  grant  such  non-employee  director  an  option  to
purchase 32,000 ordinary shares (the “Initial Grant”). Initial Grants will vest in equal tranches of
1/36th at the end of each calendar month following the date of grant, subject to continued service
by the director as of such vesting date.

In addition, in January of each year, the Board or the Compensation Committee of the Board will
grant  to  each  non-employee  director  (other  than  the  Chair)  who  has  not  announced  an  intention
either to resign from the Board or not to stand for election at the next annual general meeting of
shareholders an option to purchase 19,000 ordinary shares, and the Chair will be granted an option
to purchase 38,000 ordinary shares (the “Annual Grant”). If a new non-employee director joins the
Board following the  date  of  grant  of  the  Annual  Grant  in  any  calendar  year,  such non-employee
director will be granted a pro-rata portion of the next Annual Grant, based on the time between his
or her appointment and the date of such Annual Grant.  Annual Grants shall be vested in full as of
the date of grant.

B.     CASH FEES

Each non-employee director will receive an annual cash fee for service on the Board and for
service on each committee of which the director is a member. The chairs of the Board and of each
committee will receive higher fees for such service. The amounts of the fees paid to each non-
employee director for service on the Board and for service on each committee of the board of
directors on which the director is a member are as follows:

Board of Directors
Audit Committee
Compensation Committee
Nominating and Corporate Governance Committee

These  fees  are  payable  in  arrears  in  twelve  equal  monthly  installments,  subject  to  deduction  of
applicable income tax or national insurance which the Company is required by law to deduct and
any other statutory deductions, provided that (i) the amount of such payment shall be prorated for
any  portion  of  such  month  during  which  the  director  was  not  serving  and  (ii)  no  fee  shall  be
payable in respect of any period prior to the date of the Company’s initial public offering. 

C.

EXPENSES

The  reasonable  expenses  incurred  by  non-employee  directors  in  connection  with  attendance  at
Board  or  committee  meetings  or  other  Company-related  activities  will  be  reimbursed  upon
submission of appropriate documentation.

D.     ADMINISTRATION

to interpret these provisions and approve changes from time to time as it deems appropriate.

H.

I.

Whereas,  Pepscan  is  the  registered  owner  of  European  patent  [***]  and  its  counterparts,  and
further  patents  and  patent  applications  of  the  patent  family  of  PCT-application  WO  2004  /
0077062.

Whereas,  the  Parties  are  in  on-going  litigation  in  the  Netherlands  before  the  District  Court  The
Hague  (case  number  C/09/518528  /  HA  ZA  16-1091),  the  Court  of  Appeal  The  Hague  (case
number  200.246.353/01)  and 
the  Dutch  Supreme  Court  (case  number  20/01602)  (the
"Proceedings").

Whereas,  the  Parties  are  in  ongoing  inter partes  review  proceedings  before  the  Patent  Trial  and
Appeal  Board  of  the  United  States  Patent  and  Trademark  Office  ("PTAB")  against  patents  US
8,742,070  and  US  8,748,105  (case  numbers  IPR  2020-01569  and  IPR  2020-01626)  (the  "Inter
Partes Reviews").

Whereas, the Parties are in ongoing invalidity proceedings before the Bundespatentgericht against
patent [***], the German part of [***] (filed on 7 September 2020, with case number 3 Ni 25/20
(EP)).

Whereas,  Pepscan  Presto  BV  and  Pepscan  Systems  BV  (collectively,  the  "Licensor")  granted
BicycleRD  Limited  a  licence  under  the  Pepscan  Know-How  and  under  the  Pepscan  Patents  (as
defined in clauses 1.1.12 and 1.1.13, respectively) in a licence agreement of 13 August 2009 (the
"PLA 2009"), replaced by a licence agreement of 1 July 2010 (the "PLA 2010").  The PLA 2009
and the PLA 2010 included an obligation for the parties to negotiate in good faith to conclude a
service  agreement  pursuant  to  which  Pepscan  Presto  BV  would  serve  as  BicycleRD  Limited’s
exclusive supplier for the synthesis of so-called CLIPS peptides (article 3.2 of PLA 2010), and an
obligation for BicycleRD Limited to keep secret and confidential all know-how communicated to
it by the Licensor (article 6 of PLA 2010).

Whereas, BicycleRD Limited and Pepscan Presto BV concluded a Framework Service Agreement
of 15 March 2010, which was terminated by BicycleRD Limited by letter of 22 May 2015 with
effect from 22 August 2015 (the "FSA").

Whereas, the Licensor terminated the PLA 2010 with immediate effect by letter of 17 March 2016,
which  termination  was  confirmed  by  the  Court  of  Appeal  The  Hague,  which  termination  is
currently the subject of the Supreme Court appeal.

Whereas, the Parties are in dispute about the Licensor’s right to terminate the PLA 2010 and about
the continued exploitation of the Pepscan Know-How and Pepscan Patents (as defined in clauses
1.1.12  and  1.1.13,  respectively).  As  an  alternative  defence  against  the  consequences  of  the
Licensor’s  termination  of  the  PLA  2010,  BicycleRD  Limited  filed  a  conditional  nullity  claim
against the Dutch part of Pepscan’s European patent [***], a nullity claim against the German part
of  Pepscan’s  European  patent  [***]  and  the  Inter  Partes  Reviews  (collectively,  the  "Bicycle
Nullity Actions").

Whereas, in the Proceedings, the District Court held (decision of 18 April 2018) that Bicycle did
not  breach  article  3.2  of  the  PLA  2010  by  breaching  or  terminating  the  FSA,  but  that  "it  seems
likely" that BicycleRD Limited shared confidential know-how of the Licensor with third parties in
breach of article 6 of the PLA 2010.  Bicycle categorically refute this assumption and were entitled
to  submit  evidence  to  challenge  it;  this  matter  is  still  outstanding.    The  Court  of  Appeal
subsequently found (decision of 18 February 2020) that BicycleRD Limited had breached article
3.2 of the PLA 2010 by ordering

4
[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it
is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

CLIPS peptides from third party suppliers without the prior consent of the Licensor, and that the
Licensor had the right to terminate the PLA 2010. BicycleRD Limited appealed the decision of the
Court of Appeal to the Supreme Court.  Other grounds for the Licensor’s termination of the PLA
2010, the issue as to whether the Licensor supplied any know-how to Bicycle and whether Bicycle
used  any  such  know-how  or  shared  such  know-how  with  third  parties,  and  the  Bicycle  Nullity
Actions, are still pending before the District Court.

AUDIT RIGHTS

Pepscan shall be entitled to procure access to any of Bicycle's records to verify the achievement
(or not) of the milestones under clauses 4.4  and  4.5 ("Audit"),  provided  that  Pepscan  shall  only
procure  such  Audit  by  appointing  an  external,  reputable,  independent  and  international  firm  of
registered  accountants  that  can  cover  both  Europe  and  the  United  States  of  America  and  which
have offices in both such jurisdictions ("Auditors") and Pepscan shall not conduct the Audit itself
and/or with the assistance of any Pepscan personnel.

The  Auditors  shall  be  bound  by  confidentiality  provisions  consistent  with  those  contemplated  in
clause 10 (Confidentiality) below,  and  Bicycle  reserves  the  right  to  require  the  Auditors  to  enter
into a separate confidentiality agreement directly with Bicycle prior to the Auditors commencing
with the Audit.  For the avoidance of doubt, Pepscan shall not be entitled to have any access to
and/or have sight of Bicycle's records that are the subject of the Audit, and Pepscan shall therefore
rely on the formal report issued by the Auditors following the completion of the Audit.

Pepscan shall provide at least [***] notice of its intention to procure an Audit, and any Audit shall
be conducted by the Auditors during business hours.

Subject  to  Bicycle's  confidentiality  obligations,  Bicycle  shall  provide  the  Auditors  with  all
reasonable co-operation, access and assistance in relation to each Audit.

Pepscan  shall  use  its  reasonable  endeavours  to  ensure  that  the  conduct  of  each  Audit  does  not
unreasonably  disrupt  Bicycle  and  that  individual  Audits  are  co-ordinated  with  each  other  to
minimise any disruption.  The Parties agree that there shall be no more than one (1) Audit per Year.

Irrespective  of  the  outcome  of  any  Audit,  the  Parties  shall  bear  their  own  costs  and  expenses
incurred in respect of the conduct of Audits and their compliance with their obligation under this
clause 9 (Audit Rights).

Each  Bicycle  Party  shall,  and  shall  procure  that  its  sub-licensees  with  which  it  enters  a  licence
agreement for BT1718 and/or THR149 after the Effective Date shall, keep true, complete, separate
and  detailed  records  and  books  containing  all  data  reasonably  required  for  the  computation  and
verification of the achievement of the milestones set out in clauses 4.4 and 4.5.  Within not more
than  [***]  from  the  Effective  Date,  Bicycle  shall  request  the  same  from  any  sub-licensees  with
which it entered a licence agreement for BT1718 and/0r THR149 before the Effective Date.

10.

CONFIDENTIALITY

10.1

The  terms  of  this  Settlement  and  Licence  Agreement  and  the  negotiations  which  led  to  it  are  to
remain confidential between the Parties (the "Confidential Information"), save that they may be
disclosed:

10.1.1

by any Party with the prior written consent of the other Party;

13

is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

10.1.2

10.1.3

10.1.4

subject to clause 10.3, by any Party to its respective professional advisers or auditors, to
the extent necessary to enable them to perform their functions properly for such Party;

subject  to  clause  10.3,  by  any  Party  to:  (i)  potential  acquirors  (and  their  respective
professional  advisers),  to  the  extent  necessary  to  enable  them  to  consider,  evaluate,
negotiate and/or advance a potential acquisition or transaction related to that Party; and
(ii) financing sources (and their respective professional advisers), to the extent necessary
to  enable  them  to  consider,  evaluate,  negotiate  and/or  advance  a  potential  financing
transaction related to that Party;

by any Party to the extent such disclosure is, in the reasonable opinion of such Party’s
legal counsel, required to be disclosed pursuant to law, regulation or a valid order of a
court  of  competent  jurisdiction  or  other  governmental  body  of  competent  jurisdiction
(including, for the avoidance of doubt, the U.S. Securities and Exchange Commission);
provided  that  the  Party  intending  to  make  the  disclosure  shall,  to  the  extent  legally
permissible, first have given prompt written notice (and to the extent practicable, at least
[***])  to  the  other  Party  and  give  the  other  Party  a  reasonable  opportunity  to  take
whatever  action  it  deems  necessary  to  protect  its  Confidential  Information.    If  no
protective  order  or  other  remedy  is  obtained,  the  Party  making  the  disclosure  shall
furnish  only  that  portion  of  Confidential  Information  which  such  Party  is  advised  by
counsel is legally required to be disclosed.

10.2

10.3

10.4

10.5

In the event that a given Party is required to make a disclosure pursuant to the above clause 10.1,
the other Party will be permitted to disclose the same information should it wish to do so provided
such disclosure shall be made under and/or pursuant to the same confidentiality protections (if any)
under which the first Party made the disclosure, including as set out in clause 10.1.4.

To the extent that a Party discloses Confidential Information to the third parties contemplated in
clauses 10.1.2 and/or 10.1.3 above (as applicable) ("Authorised Persons"), such disclosure shall
be on a "need-to-know" basis and made solely for the purposes contemplated in clauses 10.1.2 and
10.1.3 (as applicable), and the Party disclosing the Confidential Information shall:

10.3.1

10.3.2

inform all such Authorised Persons that the Confidential Information is confidential and
subject to the terms contemplated in this clause 10 (Confidentiality);

ensure that all such Authorised Persons are under a duty of confidentiality or otherwise
enter into written confidentiality agreements with it on terms consistent with this clause
10 (Confidentiality); and

10.3.3

be responsible for all acts and omissions of Authorised Persons as though they were its
own acts or omissions under this clause 10 (Confidentiality).

The  Parties  shall  not  use  the  Confidential  Information  other  than  as  contemplated  by  this
Settlement and Licence Agreement.

The provisions of this clause 10 (Confidentiality) shall not apply to any information which at the
time of its disclosure was already generally available to the public other than by reason of a breach
of the terms of this Settlement and Licence Agreement, or

14
[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it
is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

otherwise becomes part of the public domain other than by reason of a breach of the terms of this
Settlement and Licence Agreement.

10.6 Without  prejudice  to  any  other  rights  or  remedies  that  any  Party  may  have,  each  Party
acknowledges and agrees that damages alone would not be an adequate remedy for any breach of
the  terms  of  this  clause  10  (Confidentiality).    Accordingly,  each  Party  shall  be  entitled  to  the
remedies of injunctions, specific performance or other equitable relief for any threatened or actual
breach of this clause 10 (Confidentiality).

11.

or  other  similar  transaction  resulting  in  the  Acquirer  (or  persons  acting  in  concert  with  the
Acquirer) holding (whether by one or a series of related transactions) all the shares in the Target,
the Target undertakes to Bicycle or Pepscan (as applicable) that it shall not as a part of such sale or
other transfer of the entire issued share capital or merger, scheme of arrangement or other similar
transaction take any actions that would result in the Target ceasing to be bound by the rights and
obligations under this Settlement and Licence Agreement.

12.2

Party,  a  power  of  attorney  in  the  form  contained  in  Annex 5 (Power  of  Attorney)  and
deliver  the  original  of  such  power  of  attorney  concurrently  with  the  execution  of  any
such sale, transfer or other means of disposition pursuant to this clause 12.2.1; and

the  successor 

in 

to

if  there  is  a  sale,  transfer  or  other  means  of  disposition  (including  by  means  of  out-
license) of any of the Pepscan Patents and/or the Pepscan Know-How by any Pepscan
Party ("Transferor"), including a sale, transfer or other disposition (including by means
of  out-license)  of  one  or  more  of  the  Pepscan  Patents  or  the  Pepscan  Know-How  to  a

Pepscan  under  clauses  3  (Grant  of  Licences)  and  6  (Withdrawal  of  Proceedings  and
Release);  and  (ii)  procure  that  such  Affiliate,  new  entity  or  separate  division  of  the

Party,  a  power  of  attorney  in  the  form  contained  in  Annex 5 (Power  of  Attorney)  and
deliver  the  original  of  such  power  of  attorney  concurrently  with  the  execution  of  any
such sale, transfer or other means of disposition pursuant to this clause 12.2.2.

12.3

power  of  attorney  in  accordance  with  clauses  12.2.1, 12.2.2  or  12.4  of  this  Settlement

applicable)  shall  also  be  contractually  bound  to  Bicycle  by  the  rights  and
obligations  under  clauses  3  (Grant  of  Licences)  and  6  (Withdrawal  of
Proceedings and Release).

12.4

In order to facilitate the transfer of rights and obligations set out in sub-clauses 12.2.1 and 12.2.2
and  clause  12.3:  (i)  the  other  Party  ("Remaining  Party")  agrees  to  do  all  acts  and  things,  and
provide  the  Transferor  with  all  assistance  (including  the  execution  of  any  documentation),
reasonably requested in writing by the Transferor, and which is necessary, in order to effect such
transfer from the Transferor to the Transferee or Affiliate Transferee or new owner under clause
12.3.2  (as  applicable),  provided  that  such  acts  and  assistance  do  not  impose  any  additional
obligations  on  the  Remaining  Party  (other  than  the  doing  of  such  things  and  assistance);  and
(ii) each Party shall

simultaneously with the execution of this Settlement and Licence Agreement grant to the other a
power  of  attorney  in  the  form  contained  in  Annex 5 (Power  of  Attorney)  of  this  Settlement  and
Licence Agreement (with the Party acting as the attorney, in each case, to be represented by any
one entity of such Party) (and shall deliver the original of such power of attorney concurrently with
execution this Settlement and Licence Agreement) so as to permit the Transferor to execute on its
behalf any documentation required to perfect any transfer from the Transferor to the Transferee, or
Affiliate  Transferee,  or  new  owner  under  clause  12.3.2  (as  applicable),  but  not  for  any  other
purpose whatsoever.

12.5

The Transferor shall indemnify the Remaining Party and keep it indemnified from and against any
and all liabilities, costs, expenses, damages and losses suffered or incurred by the Remaining Party
arising as a result of any failure of the Transferor to secure the transfer of rights and obligations to
the  Transferee  in  accordance  with  the  provisions  of  clause  12.2  or  the  Transferor’s  failure  to
comply  with  the  terms  of  clause  12.3  (as  applicable).    The  Remaining  Party  shall  have  an
obligation  to  mitigate  any  loss,  and  shall  not  be  entitled  to  recover  any  legal  costs  or  costs  for
management time incurred in pursuing the indemnity set out in this clause 12.5.  For the avoidance
of doubt, if and to the extent that the failure of the Transferor to secure the transfer of rights and
obligations  to  the  Transferee,  Affiliate  Transferee  or  new  owner  pursuant  to  clause  12.3.2  (as
applicable) in accordance with the provisions of clause 12.2 and clause 12.3 (as applicable) or the
Transferor’s  failure  to  comply  with  the  terms  of  clause  12.3  (as  applicable)  is  a  result  of  the
Remaining  Party's  breach  of  clause  12.4,  this  indemnity  may  not  be  invoked  by  the  Remaining
Party.

12.6 Without  prejudice  to  any  other  rights  or  remedies  that  each  Party  may  have,  each  Party
acknowledges and agrees that damages alone would not be an adequate remedy for any breach of
the  terms  of  this  clause  12  (Change  of  Control).    In  particular,  with  regard  to  clause  12.4,  the
Parties recognise that significant damage shall be caused to the Transferor should the Remaining
Party not provide the necessary assistance to the Transferor, as required in accordance with such
clause  12.4.    Accordingly,  each  Party  shall  be  entitled  to  the  remedies  of  injunctions,  specific
performance or other equitable relief for any threatened or actual breach of this clause 12 (Change
of Control).

12.7

Each  Party  shall  keep  confidential  the  terms  and  existence  of  any  transaction  or  potential
transaction  to  be  implemented  by  the  other  Party  in  accordance  with  the  terms  of  this  clause  12
(Change  of  Control),  save  that  details  of  any  such  transaction  or  potential  transaction  may  be
disclosed in accordance with clauses 10.1.1, 10.1.2, 10.1.3 or 10.1.4.

Bicycle Therapeutics Announces Settlement of Patent Dispute with Pepscan Systems B.V.

CAMBRIDGE,  England,  &  BOSTON  –  [TBD],  2020  –  Bicycle  Therapeutics  plc  (NASDAQ:BCYC),  a
clinical-stage biotechnology company pioneering a new and differentiated class of therapeutics based on its
proprietary bicyclic peptide (Bicycle®) technology, today announced that it has entered into a settlement
and  license  agreement  with  Pepscan  Systems  B.V.  regarding  Bicycle’s  use  of  Pepscan’s  CLIPS  peptide
technology.  

The companies have agreed to settle all intellectual property disputes worldwide.  Under the terms of the
settlement, Bicycle has been granted a license to use CLIPS peptide technology in the development of its
product candidates BT1718 and THR-149.  Bicycle will pay €3 million upfront, will pay €1 million on the
first anniversary of the date of settlement, and will make potential additional payments to Pepscan based on
achievement of specified clinical, regulatory and commercial milestones.

About Bicycle Therapeutics
Bicycle  Therapeutics  (NASDAQ:  BCYC)  is  a  clinical-stage  biopharmaceutical  company  developing  a
novel  class  of  medicines,  referred  to  as  Bicycles®,  for  diseases  that  are  underserved  by  existing
therapeutics. Bicycles are fully synthetic short peptides constrained with small molecule scaffolds to form
two loops that stabilize their structural geometry. This constraint facilitates target binding with high affinity
and  selectivity,  making  Bicycles  attractive  candidates  for  drug  development.  Bicycle’s  lead  product
candidate, BT1718, a Bicycle Toxin Conjugate (BTC) that targets MT1-MMP, is being investigated in an
ongoing  Phase  I/IIa  clinical  trial  in  collaboration  with  the  Centre  for  Drug  Development  of  Cancer
Research  UK.  Bicycle  is  also  evaluating  BT5528,  a  second-generation  BTC  targeting  EphA2,  in  a
Company-sponsored Phase I/II study. BT8009 is a BTC targeting Nectin-4, a well-validated tumor antigen,
and  is  also  currently  being  evaluated  a  Company-sponsored  Phase  I/II  trial.  Bicycle  is  headquartered
in  Cambridge,  UK  with  many  key  functions  and  members  of  its  leadership  team  located  in  Lexington,
MA. For more information, visit bicycletherapeutics.com.

Pepscan shall withdraw from the Oppositions.

As of the Effective Date and thereafter, Pepscan releases and forever discharges any and all of the

institute any proceedings or oppositions relating to the Pepscan Released Claims, against Bicycle,

unless Bicycle commences patent infringement proceedings based on a patent within the Bicycle

Bicycles that arise from screening or otherwise, nor use or transfer outside of Pepscan,
any  Bicycles  that  arise  from  screening  or  otherwise,  to  the  extent  (i)  that  the  activity
giving  rise  to  the  information  or  the  Bicycle(s)  would,  absent  the  release  and
undertaking  contained  in  clause  5.3,  comprise  infringement  of  any  of  the  Bicycle
Patents, or (ii) doing so would otherwise constitute an infringement or misappropriation
of any of Bicycle’s other intellectual property or other rights.

disclosure of any relevant know-how.

7.

COSTS

Each Party shall bear their own legal costs and expenses in relation to, the Oppositions as well as

CONFIDENTIALITY

The  terms  of  this  Settlement  Agreement  and  the  negotiations  which  led  to  it  are  to  remain
confidential  between  the  Parties  (the  "Confidential  Information"),  save  that  they  may  be
disclosed:

8.1.1

by any Party with the prior written consent of the other Party;

8.1.2

8.1.3

8.1.4

subject to clause 8.3, by any Party to its respective professional advisers or auditors, to
the extent necessary to enable them to perform their functions properly for such Party;

subject  to  clause  8.3,  by  any  Party  to:  (i)  potential  acquirors  (and  their  respective
professional  advisers),  to  the  extent  necessary  to  enable  them  to  consider,  evaluate,
negotiate and/or advance a potential acquisition or transaction related to that Party; and
(ii) financing sources (and their respective professional advisers), to the extent necessary
to  enable  them  to  consider,  evaluate,  negotiate  and/or  advance  a  potential  financing
transaction related to that Party;

by any Party to the extent such disclosure is, in the reasonable opinion of such Party’s
legal counsel, required to be disclosed pursuant to law, regulation or a valid order of a
court  of  competent  jurisdiction  or  other  governmental  body  of  competent  jurisdiction
(including, for the avoidance of doubt, the U.S. Securities and Exchange Commission);
provided  that  the  Party  intending  to  make  the  disclosure  shall,  to  the  extent  legally
permissible, first have given prompt written notice (and to the extent practicable, at least
[***] notice) to the other Party and give the other Party a reasonable opportunity to take
whatever  action  it  deems  necessary  to  protect  its  Confidential  Information.    If  no
protective  order  or  other  remedy  is  obtained,  the  Party  making  the  disclosure  shall
furnish  only  that  portion  of  Confidential  Information  which  such  Party  is  advised  by
counsel is legally required to be disclosed.

In the event that a given Party is required to make a disclosure pursuant to the above clause 8.1,
the other Party will be permitted to disclose the same information should it wish to do so provided
such disclosure shall be made under and/or pursuant to the same confidentiality protections (if any)
under which the first Party made the disclosure, including as set out in clause 8.1.4.

To the extent that a Party discloses Confidential Information to the third parties contemplated in
clauses 8.1.2 and/or 8.1.3 above (as applicable) ("Authorised Persons"), such disclosure shall be
on a "need-to-know" basis and made solely for the

purposes  contemplated  in  clauses  8.1.2  and  8.1.3  (as  applicable),  and  the  Party  disclosing  the
Confidential Information shall:

8.3.1

8.3.2

inform all such Authorised Persons that the Confidential Information is confidential and
subject to the terms contemplated in this clause 8 (Confidentiality);

ensure that all such Authorised Persons are under a duty of confidentiality or otherwise
enter into written confidentiality agreements with it on terms consistent with this clause
8 (Confidentiality); and

8.3.3

be responsible for all acts and omissions of Authorised Persons as though they were its
own acts or omissions under this clause 8 (Confidentiality).

The  Parties  shall  not  use  the  Confidential  Information  other  than  as  contemplated  by  this
Settlement Agreement.

The provisions of this clause 8 (Confidentiality)  shall  not  apply  to  any  information  which  at  the
time of its disclosure was already generally available to the public other than by reason of a breach
of the terms of this Settlement Agreement, or otherwise becomes part of the public domain other
than by reason of a breach of the terms of this Settlement Agreement.

Without  prejudice  to  any  other  rights  or  remedies  that  any  Party  may  have,  each  Party
acknowledges and agrees that damages alone would not be an adequate remedy for any breach of
the  terms  of  this  clause  8  (Confidentiality).    Accordingly,  each  Party  shall  be  entitled  to  the
remedies of injunctions, specific performance or other equitable relief for any threatened or actual
breach of this clause 8 (Confidentiality).

CHANGE OF CONTROL

If  there  is  an  acquisition  of  any  of  the  Pepscan  Parties  or  Bicycle  Parties  (as  applicable)
("Target"), whether by a third party or an Affiliate of the Target ("Acquirer"), meaning the sale or
other transfer of the entire issued share capital of the Target or any merger, scheme of arrangement
or  other  similar  transaction  resulting  in  the  Acquirer  (or  persons  acting  in  concert  with  the
Acquirer) holding (whether by one or a series of related transactions) all the shares in the Target,
the Target undertakes to Bicycle or Pepscan (as applicable) that it shall not as a part of such sale or
other transfer of the entire issued share capital or merger, scheme of arrangement or other similar
transaction take any actions that would result in the Target ceasing to be bound by the rights and
obligations under this Settlement Agreement.

if  there  is  a  sale,  transfer  or  other  means  of  disposition  (including  by  means  of  out-
license) of all or substantially all of the business or assets of a Party ("Transferor") to a
third  party  or  an  Affiliate,  new  entity  or  separate  division  of  the  Transferor,  the
Transferor undertakes  that  it  shall:  (i)  transfer  any  and  all  of  its  rights  and  obligations
under  this  Settlement  Agreement  to  the  successor  in  interest  ("Transferee");  and  (ii)
procure  that  such  Affiliate,  new  entity  or  separate  division  of  the  Transferor  (as

license) of any of the Bicycle Patents by any Bicycle Party ("Transferor"), including a
sale, transfer or other disposition (including by means of out-license) of one or more of
the Bicycle Patents to a third party or an Affiliate, new entity or separate division of the
Transferor, the Transferor undertakes that it shall: (i) ensure that the new owner of the
Bicycle Patents ("Transferee") shall be contractually bound to Pepscan by the rights and
obligations of Bicycle under clause 5 (Withdrawal of Oppositions and Release); and (ii)
procure  that  such  Affiliate,  new  entity  or  separate  division  of  the  Transferor  (as
applicable) shall, for the purposes of clause 9.4 of this Settlement Agreement, grant to
Pepscan, as represented by any one nominated Pepscan Party, a power of attorney in the
form contained in Annex 2 (Power of Attorney) and deliver the original of such power
of attorney concurrently with the execution of any such sale, transfer or other means of
disposition pursuant to this clause 9.2.2.

9.3

In the event that there is a sale, transfer or other disposition (including by means of out-license) by
a  Party  ("Transferor")  to  an  Affiliate,  new  entity  or  separate  division  ("Affiliate  Transferee")
pursuant to any of sub-clauses 9.2.1 or 9.2.2, and such Affiliate, new entity or separate division of
the  Transferor  (as  applicable)  is  subsequently  sold  or  transferred  by  the  applicable  Affiliate
Transferee to a third party, then the Transferor shall procure that the Affiliate Transferee either:

9.3.1

transfers such: (i) business or assets (and in each case any contracts); or (ii) the Bicycle
Patents  (as  applicable)  back  to  the  original  Transferor  (or  another  Affiliate  of  the
original  Transferor)  and  the  applicable  rights  and  obligations  under  this  Settlement
Agreement  shall  also  be  transferred  back  by  the  Affiliate  Transferee  to  the  original
Transferor  (or  another  Affiliate  of  the  original  Transferor).    To  the  extent  the  transfer
made pursuant to this clause is made to an Affiliate of the original Transferor and such
Affiliate  has  not  previously  executed  a  power  of  attorney  in  accordance  with  clauses
9.2.1, 9.2.2 or 9.4 of this Settlement Agreement, then the Transferor shall procure that
such  Affiliate  of  the  original  Transferor  shall,  for  the  purposes  of  clause  9.4  of  this
Settlement Agreement, grant to the other Party, as represented by any one entity of such
Party,  a  power  of  attorney  in  the  form  contained  in  Annex 2 (Power  of  Attorney)  and
deliver  the  original  of  such  power  of  attorney  concurrently  with  the  execution  of  any
transfer back to the Affiliate of the original Transferor pursuant to this clause 9.3.1; or

9.3.2

undertake to ensure that, as applicable:

9.3.2.1

9.3.2.2

the new owner of the business or assets shall also be contractually bound by
the rights and obligations under this Settlement Agreement; or

the  new  owner  of  the  Bicycle  Patents  shall  also  be  contractually  bound  to
Pepscan  by  the  rights  and  obligations  under  clause  5  (Withdrawal  of
Oppositions and Release).

9.4

In order to facilitate the transfer of rights and obligations set out in sub-clauses 9.2.1 and 9.2.2 and
clause 9.3: (i) the other Party ("Remaining Party") agrees to do all acts and things, and provide
the  Transferor  with  all  assistance  (including  the  execution  of  any  documentation),  reasonably
requested in writing by the Transferor, and which is

10
[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it
is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

necessary,  in  order  to  effect  such  transfer  from  the  Transferor  to  the  Transferee  or  Affiliate
Transferee or new owner under clause 9.3.2 (as applicable), provided that such acts and assistance
do  not  impose  any  additional  obligations  on  the  Remaining  Party  (other  than  the  doing  of  such
things  and  assistance);  and  (ii)  each  Party  shall  simultaneously  with  the  execution  of  this
Settlement  Agreement  grant  to  the  other  a  power  of  attorney  in  the  form  contained  in  Annex  2
(Power of Attorney) of this Settlement Agreement (with the Party acting as the attorney, in each
case,  to  be  represented  by  any  one  entity  of  such  Party)  (and  shall  deliver  the  original  of  such
power  of  attorney  concurrently  with  execution  this  Settlement  Agreement)  so  as  to  permit  the
Transferor  to  execute  on  its  behalf  any  documentation  required  to  perfect  any  transfer  from  the
Transferor  to  the  Transferee,  or  Affiliate  Transferee,  or  new  owner  under  clause  9.3.2  (as
applicable), but not for any other purpose whatsoever.

The Transferor shall indemnify the Remaining Party and keep it indemnified from and against any
and all liabilities, costs, expenses, damages and losses suffered or incurred by the Remaining Party
arising as a result of any failure of the Transferor to secure the transfer of rights and obligations to
the Transferee in accordance with the provisions of clause 9.2 or the Transferor’s failure to comply
with  the  terms  of  clause  9.3  (as  applicable).    The  Remaining  Party  shall  have  an  obligation  to
mitigate any loss, and shall not be entitled to recover any legal costs or costs for management time
incurred in pursuing the indemnity set out in this clause 9.5.  For the avoidance of doubt, if and to
the extent that the failure of the Transferor to secure the transfer of rights and obligations to the
Transferee,  Affiliate  Transferee  or  new  owner  pursuant  to  clause  9.3.2  (as  applicable)  in
accordance  with  the  provisions  of  clause  9.2  and  clause  9.3  (as  applicable)  or  the  Transferor’s
failure to comply with the terms of clause 9.3 (as applicable) is a result of the Remaining Party's
breach of clause 9.4, this indemnity may not be invoked by the Remaining Party.

Without  prejudice  to  any  other  rights  or  remedies  that  each  Party  may  have,  each  Party
acknowledges and agrees that damages alone would not be an adequate remedy for any breach of
the terms of this clause 9 (Change of Control).  In particular, with regard to clause 9.4, the Parties
recognise that significant damage shall be caused to the Transferor should the Remaining Party not
provide the necessary assistance to the Transferor, as required in accordance with such clause 9.4.
 Accordingly, each Party shall be entitled to the remedies of injunctions, specific performance or
other equitable relief for any threatened or actual breach of this clause 9 (Change of Control).

Each  Party  shall  keep  confidential  the  terms  and  existence  of  any  transaction  or  potential
transaction  to  be  implemented  by  the  other  Party  in  accordance  with  the  terms  of  this  clause  9
(Change  of  Control),  save  that  details  of  any  such  transaction  or  potential  transaction  may  be
disclosed in accordance with clauses 8.1.1, 8.1.2, 8.1.3 or 8.1.4.

2

and confirmed in all respects.  Lenders’ and Agent’s execution and delivery of, or acceptance of, this Amendment shall
not be deemed to create a course of dealing or otherwise create any express or implied duty by any of them to provide
any other or further amendments, consents or waivers in the future.  

(ii)

Each  of  the  Borrowers  hereby  expressly  (1)  reaffirms,  ratifies  and  confirms  its  Secured

grant  of  security  under  Section  3.1  of  the  Existing  Loan  Agreement,  (3)  reaffirms  that  such  grant  of  security  in  the

such grant of security in the Collateral: (x) remains in full force and effect notwithstanding the amendments expressly

(iii)

This Amendment is not a novation and the terms and conditions of this Amendment shall be
in  addition  to  and  supplemental  to  all  terms  and  conditions  set  forth  in  the  Loan  Documents.  Nothing  in  this
Amendment  is  intended,  or  shall  be  construed,  to  constitute  an  accord  and  satisfaction  of  Borrowers’  Secured
Obligations  under  or  in  connection  with  the  Existing  Loan  Agreement  and  any  other  Loan  Document  or  to  modify,
affect or impair the perfection or continuity of Agent’s security interest in, (on behalf of itself and Lenders) security
titles to or other liens on any Collateral for the Secured Obligations.

(b)

Conditions.    For  purposes  of  determining  compliance  with  the  conditions  specified  in  Section  3,
Lenders  that  have  signed  this  Amendment  shall  be  deemed  to  have  consented  to,  approved  or  accepted  or  to  be

Release.  In consideration of the agreements of Agent and Lenders contained herein and for other
good  and  valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby  acknowledged,  each  Borrower,  on
behalf of itself and its successors, assigns, and other legal representatives, hereby fully, absolutely, unconditionally and
irrevocably releases, remises and forever discharges Agent and Lenders, and its successors and assigns, and its present
and  former  shareholders,  affiliates,  subsidiaries,  divisions,  predecessors,  directors,  officers,  attorneys,  employees,
agents and other representatives (Agent, Lenders and all such other persons being hereinafter referred to collectively as
the “Releasees” and individually as a “Releasee”), of and from all demands, actions, causes of action, suits, covenants,
contracts, controversies, agreements, promises, sums of money, accounts, bills, reckonings, damages and any and all
other claims, counterclaims, defenses, rights of set-off, demands and liabilities whatsoever of every name and nature,
known or unknown, suspected or unsuspected, both at law and in equity, which  Borrower, or any of its successors,
assigns, or other legal representatives may now or hereafter own, hold, have or claim to have against the Releasees or
any of them for, upon, or by reason of any circumstance, action, cause or thing whatsoever which arises at any time on
or prior to the day and date of this Amendment for or on account of, or in relation to, or in any way in connection with
the  Loan  Agreement,  or  any  of  the  other  Loan  Documents  or  the  transactions  thereunder  or  related  thereto.    Each
Borrower waives the provisions of California Civil Code section 1542, which states:

A  GENERAL  RELEASE  DOES  NOT  EXTEND  TO  CLAIMS  THAT  THE  CREDITOR  OR
RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT
THE  TIME  OF  EXECUTING  THE  RELEASE  AND  THAT,  IF  KNOWN  BY  HIM  OR  HER,
WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR
OR RELEASED PARTY.

Each  Borrower  understands,  acknowledges  and  agrees  that  the  release  set  forth  above  may  be  pleaded  as  a  full  and
complete defense and may be used as a basis for an injunction against any action, suit or other proceeding which may
be instituted, prosecuted or attempted in breach of the provisions of such release.  Each Borrower agrees that no fact,
event, circumstance, evidence or transaction which could now be asserted or which may hereafter be discovered shall
affect in any manner the final, absolute and unconditional nature of the release set forth above.  The provisions of this
section shall survive payment in full of the Secured Obligations, full performance of all the terms of this Amendment
and the other Loan Documents.

3

(d)

No Reliance.    Borrowers  hereby  acknowledge  and  confirm  to  Agent  and  Lenders  that  each  such
Borrower is executing this Amendment on the basis of its own investigation and for its own reasons without reliance
upon any agreement, representation, understanding or communication by or on behalf of any other Person.

(e)

Costs and Expenses.  Borrowers agree to pay to Agent on the date hereof the out-of-pocket costs
and  expenses  of  Agent  and  Lenders  party  hereto,  and  the  fees  and  disbursements  of  counsel  to  Agent  and  Lenders
party hereto in connection with the negotiation, preparation, execution and delivery of this Amendment and any other
documents to be delivered in connection herewith on the date hereof.

(f)
assigns of each party.  

Binding  Effect.    This  Amendment  binds  and  is  for  the  benefit  of  the  successors  and  permitted

(g)

Governing  Law.    This  Amendment  and  the  other  Loan  Documents  shall  be  governed  by,  and
construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws principles
that would cause the application of laws of any other jurisdiction.

(h)

Complete  Agreement;  Amendments.    This  Amendment  and  the  Loan  Documents  represent  the
entire agreement about this subject matter and supersede prior negotiations or agreements with respect to such subject
matter.  All prior agreements, understandings, representations, warranties, and negotiations between the parties about
the subject matter of this Amendment and the Loan Documents merge into this Amendment and the Loan Documents.

(i)

Severability  of  Provisions.    Each  provision  of  this  Amendment  is  severable  from  every  other

provision in determining the enforceability of any provision.

(j)

Counterparts.  This Amendment may be executed in any number of counterparts and by different
parties  on  separate  counterparts,  each  of  which,  when  executed  and  delivered,  is  an  original,  and  all  taken  together,
constitute one Amendment.  Delivery of an executed counterpart of a signature page of this Amendment by facsimile,
portable document format (.pdf) or other electronic transmission will be as effective as delivery of a manually executed
counterpart hereof.

(k)
Documents.

Loan  Documents.  This  Amendment  and  the  documents  related  thereto  shall  constitute  Loan

(l)

Electronic Execution of Certain Other Documents.  The words “execution,” “execute”, “signed,”
“signature,” and words of like import in or related to any document to be signed in connection with this Amendment
and  the  transactions  contemplated  hereby  (including  without  limitation  assignments,  assumptions,  amendments,
waivers and consents) shall be deemed to include electronic signatures, the electronic matching of assignment terms
and contract formations on electronic platforms approved by Agent, or the keeping of records in electronic form, each
of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a
paper-based  recordkeeping  system,  as  the  case  may  be,  to  the  extent  and  as  provided  for  in  any  applicable  law,
including the Federal Electronic Signatures in Global and National Commerce Act, the California Uniform Electronic
Transaction Act, or any other similar state laws based on the Uniform Electronic Transactions Act.
