Our business is subject to numerous risks and uncertainties, including those described in Part I, Item 1A. “Risk Factors” in this Annual Report on Form 10-
K. You should carefully consider these risks and uncertainties when investing in our common shares. The principal risks and uncertainties affecting our
business include the following:
SUMMARY RISK FACTORS
•
•
•
•
•
•
We have incurred significant net losses since our inception and we expect to continue to incur significant expenses and operating losses for
the foreseeable future.
We have a limited operating history, have not completed any registrational clinical trials, and have no products approved for commercial sale,
which may make it difficult for you to evaluate our current business and predict our future success and viability.
We will require substantial additional capital to finance our operations. If we are unable to raise such capital when needed, or on acceptable
terms, we may be forced to delay, reduce or eliminate one or more of our research and drug development programs or future
commercialization efforts.
The outcome of pre-clinical testing and early clinical trials may not be predictive of the success of later clinical trials, and the results of our
clinical trials may not satisfy the requirements of the FDA, EMA or other comparable foreign regulatory authorities.
The clinical trial and regulatory approval processes are lengthy, time consuming, require compliance with extensive regulations and
consistent with appropriate quality, and are inherently unpredictable, and we may incur additional costs or experience delays in completing,
or ultimately be unable to complete, the development and commercialization of our product candidates.
Our antibody candidates may have serious adverse, undesirable or unacceptable side effects alone or in combinations being tested in clinical
development, which may delay or prevent marketing approval. If such side effects are identified
1
•
•
•
•
•
•
•
•
during the development of our antibody candidates or following approval, if any, we may need to abandon our development of such antibody
candidates, the commercial profile of any approved label may be limited, or we may be subject to other significant negative consequences
following marketing approval, if any.
We have never commercialized an antibody candidate before and may lack the necessary expertise, personnel and resources to successfully
commercialize our products on our own or together with suitable future collaborators or partners.
We rely, and expect to continue to rely, on third parties, including independent clinical investigators and contract research organizations or
CROs, to conduct our pre-clinical studies, clinical trials, chemistry, manufacturing and controls and potential development of a companion
diagnostic. If these third parties do not successfully carry out their contractual duties, meet expected deadlines, perform with the requisite
level of compliance and quality, or perform at reasonable cost, we may not be able to obtain regulatory approval for or commercialize our
antibody candidates or we may be subject to other significant negative consequences prior to, upon application for or following marketing
approval, if any, and our business could be substantially harmed.
Due to our limited resources and access to capital, we must, and have in the past decided to, prioritize development of certain antibody
candidates over other potential candidates. These decisions may prove to have been wrong and may adversely affect our revenues.
The competition for qualified personnel is particularly intense in our industry. If we are unable to retain or hire key personnel, we may not be
able to sustain or grow our business.
We operate in highly competitive and rapidly changing industries, and if our competitors develop and market technologies or products more
rapidly than we do or that are more effective, safer or less expensive than the product candidates we develop, our commercial opportunities
will be negatively impacted.
Our success depends on our ability to protect our intellectual property and our proprietary technologies. If we are unable to adequately
protect our intellectual property and our proprietary technologies or obtain and maintain issued patents which are sufficient to protect our
product candidates and proprietary technologies, or if others do not respect our intellectual property rights and exclusivity, others could
compete against us more directly, which would negatively impact our business.
Our existing collaboration agreements are important to our business and potential future collaborations and licenses may also be important to
us, and if we are unable to maintain any of these collaborations or execute new collaborations or licenses, or if these arrangements are not
successful, our business could be adversely affected.
The trading prices for our and other biopharmaceutical companies’ stock have been highly volatile as a result of disruptions and extreme
volatility in the global economy, including rising inflation and interest rates, declines in economic growth, global instability, including the
ongoing conflicts in Europe and the Middle East, which have and may continue to adversely impact our business, including our pre-clinical
studies and clinical trials, financial condition, our ability to raise capital and results of operations.

Item 1. Business.
Overview
PART I
We are a clinical-stage oncology company developing innovative antibody therapeutics. Our pipeline of full-length, human, multispecific antibody
candidates is generated from our proprietary technology platforms, which are able to generate a diverse array of antibody binding domains, or Fabs, against
virtually any target. Our antibody binding domain generally consist of a target-specific heavy chain paired with a common light chain. Multiple binding
domains can be combined to produce novel multispecific antibodies that bind to a wide range of targets and display novel and innovative biology. These
platforms, referred to as Biclonics® and Triclonics®, allow us to generate large numbers of diverse panels of bispecific and trispecific antibodies,
respectively, which can then be functionally screened in large-scale cell-based assays to identify those unique molecules that possess novel biology, which
we believe are best suited for a given therapeutic application. Further, by binding to multiple targets, Biclonics® and Triclonics® may be designed to
provide a variety of mechanisms of action, including simultaneously blocking receptors that drive tumor cell growth and survival and mobilizing the
patient’s immune response by engaging T cells, and/or activating various killer cells to eradicate tumors.
Our technology platforms employ an assortment of patented technologies and techniques to generate human antibodies. We utilize our patented MeMo®
mouse to produce a host of antibodies with diverse heavy chains and a common light chain that are capable of binding to virtually any antigen target. We
use our patented heavy chain and CH3 domain dimerization technology to generate substantially pure bispecific and trispecific antibodies. We also employ
our patented Spleen to Screen® technology to efficiently screen panels of diverse heavy chains, designed to allow us to more rapidly identify Biclonics®
and Triclonics® therapeutic candidates with differentiated modes of action for pre-clinical and clinical testing.
Using our Biclonics® platform we have produced, and are currently developing, the following candidates: MCLA-158 (petosemtamab) for the potential
treatment of solid tumors; MCLA-128 (zenocutuzumab or Zeno) for the potential treatment of solid tumors that harbor Neuregulin 1 (NRG1) gene fusions;
MCLA-129, for the potential treatment of lung and other solid tumors; and MCLA-145 for the potential treatment of solid tumors. Furthermore, we have a
pipeline of proprietary antibody candidates in pre-clinical development and intend to further leverage our Biclonics® and Triclonics® technology platforms
to identify multiple additional antibody candidates and advance them to clinical development.
Our Strategy
Our goal is to become a leading oncology company developing innovative multispecific antibodies to treat various types of cancer. Our business strategy
comprises the following components:
•
•
Successfully develop our lead bispecific antibody candidate MCLA-158, petosemtamab. We are developing petosemtamab for a potential
dual EGFR/LRG5 blockade for the treatment of solid tumors. Petosemtamab is in clinical development in the expansion part of a phase 1/2
open-label, multicenter trial evaluating petosemtamab monotherapy in patients with advanced solid tumors, including previously treated
advanced (recurrent or metastatic) head and neck squamous cell carcinoma (HNSCC). We are currently evaluating approximately 40 patients
in previously treated (2L/3L) HNSCC with petosemtamab monotherapy at the 1100 or 1500 mg dose levels to confirm a suitable dose for
future potential randomized trials. We plan to share clinical data from this cohort in the second half of 2024. Based on these data and
additional information and analyses, we anticipate potentially initiating a randomized phase 3 trial of petosemtamab monotherapy, or
investigators’ choice of single agent chemotherapy or cetuximab in 2L/3L HNSCC. We anticipate such a trial could potentially start in mid-
2024. We plan to report interim clinical data from the 2L/3L cohort in monotherapy, including the dose evaluation cohort in 2024. We are
further developing petosemtamab in combination with pembrolizumab, a PD-1 blocking antibody, investigating this combination in patients
with untreated HNSCC expressing PD-L1 (CPS > 1) to evaluate safety and clinical activity in this population. We believe initial safety data
from this single arm cohort may support the initiation of a first-line registration trial with this combination. We plan to report initial interim
clinical data from this cohort in the second quarter of 2024. Among the initial patients dosed in the first-line combination, the combination
has been observed to be generally well tolerated. The U.S. Food and Drug Administration (FDA) has granted Fast Track Designation for the
investigation of petosemtamab for the treatment of patients with recurrent or metastatic HNSCC whose disease has progressed following
treatment with platinum-based chemotherapy and an anti-programmed cell death protein 1 (anti-PD-1) antibody. In 2024, we also plan to
evaluate petosemtamab in 2L colorectal cancer patients.
Successfully develop our most advanced bispecific antibody candidate, zenocutuzumab (Zeno), for the treatment of NRG1 fusion solid
tumors, and explore other potential indications in non-NRG1 fusion cancers by targeting both HER2 and HER3. We are developing our
most advanced bispecific antibody candidate, Zeno, for the potential treatment of solid tumors that contain NRG1 gene fusions. The NRG1
protein is the ligand for the HER3 receptor—a known cause
3
of cancer cell growth. The gene encoding NRG1 can form genetic rearrangements referred to as NRG1 gene fusions. The protein product of
the NRG1 gene fusion can drive signaling through the HER3 receptor and thus drive cancer cell growth. NRG1 gene fusions (NRG1+) occur
infrequently in a wide range of different cancer types. Zeno has been shown pre-clinically to potently disrupt binding of NRG1 (and NRG1-
fusion proteins) to HER3 and halt NRG1-stimulated tumor cell growth. In July 2020, the FDA granted Zeno orphan drug designation for the
treatment of patients with pancreatic cancer and in January 2021, the FDA granted Fast Track Designation to Zeno for the treatment of
patients with metastatic solid tumors harboring NRG1 gene fusions that have progressed on standard-of-care therapy. In July, 2023, we
announced that the FDA has granted Breakthrough Therapy Designation (BTD) to Zeno for the treatment of patients with advanced
unresectable or metastatic NRG1 fusion-positive (NRG1+) pancreatic cancer following progression with prior systemic therapy or who have
no satisfactory alternative treatment options. Additionally, the FDA has granted BTD to Zeno for the treatment of patients with advanced
unresectable or metastatic NRG1+ non-small cell lung cancer (NSCLC), following progression with prior systemic therapy. Based on
productive and collaborative discussions we have had with the FDA in context of the two BTDs, we believe we will have sufficient clinical
data in the first half of 2024 to support potential Biologics License Application (BLA) submissions in NRG1+ NSCLC and NRG1+ PDAC.
We believe that obtaining a commercialization partnership agreement will be an essential step in bringing Zeno to patients with NRG1+
cancer, if approved. We have also paused enrollment and are also following patients treated with Zeno in combination with an androgen
deprivation therapy (enzalutamide or abiraterone) in castration resistant prostate cancer, irrespective of NRG1+ status. We have also paused
enrollment and are also following patients treated with Zeno in combination with afatinib for patients with NRG1+ NSCLC.
•
•
•
•
Successfully develop our bispecific antibody candidate MCLA-129. We are developing MCLA-129 as a potential treatment for solid tumors,
including NSCLC. In May 2021, we announced that the first patient was treated in the phase 1/2 dose escalation and expansion trial evaluating
MCLA-129 for the treatment of patients with advanced NSCLC and other solid tumors. We presented a clinical update on MCLA-129 from
ongoing expansion cohorts in NSCLC and in previously treated HNSCC at the ESMO Asia Congress 2023. We continue to follow patients
with EGFRm NSCLC treated with MCLA-129 in combination with osimertinib, a third generation EGFR tyrosine kinase inhibitor, to evaluate
potential for biomarkers as a means to maximize efficacy, while proactively addressing safety signals seen to date. Based on the results to date,
we are encouraged by the potential for MCLA-129 in the treatment of cancer are evaluating focused investment opportunities. We plan to start
a cohort of MCLA-129 in combination with chemotherapy in 2L+ EGFRm NSCLC in 2024. Additionally, we are continuing investigation of
cohort B evaluating MCLA-129 in patients with MET exon14 skipping NSCLC. We also remain interested in exploring partnering MCLA-129
with other companies to sufficiently resource the development of MCLA-129 and potential benefit it may have for patients. MCLA-129 is
subject to a collaboration and license agreement between Merus and Betta Pharmaceuticals Co. Ltd. (Betta), whereby Merus exclusively
licensed Betta to develop MCLA-129 in China, while Merus retains full ex-China rights.
Successfully develop our bispecific antibody candidate MCLA-145. We are developing MCLA-145 for the potential treatment of solid tumors.
MCLA-145 is designed to recruit, activate and prevent the exhaustion of tumor-infiltrating T-cells. MCLA-145 is in clinical development in a
global, phase 1, open-label, clinical trial evaluating MCLA-145 in patients with solid tumors. The trial is in the dose expansion phase, and we
continue to monitor and evaluate patients on treatment with the combination of MCLA-145 with pembrolizumab.
Accelerate the discovery and development of additional internal and collaboration-related bispecific antibody candidates and trispecific
antibody candidates. We believe we are well positioned to expand our pipeline of Biclonics® and Triclonics® molecules for the potential
treatment of cancer and potentially other forms of disease. We are conducting pre-clinical studies for our internal proprietary bispecific and
trispecific pipeline as well as leveraging our bispecific platform with our collaborators including Incyte, Eli Lilly and Company (Eli Lilly) and
Betta.
Seek strategic collaborations. We intend to seek strategic collaborations to facilitate the capital-efficient development of our pipeline and to
maximize the value of our Biclonics® and Triclonics® technology platforms and to access unique partner capabilities and capacity. We have
entered into collaborations with Incyte, Eli Lilly, and Betta to develop bispecific antibody candidates based on our Biclonics® technology
platform. We plan to work with other potential future collaborators to further validate and expand the use of our Biclonics® and Triclonics®
platforms in developing bispecific and trispecific antibody candidates. We have also worked with Ono Pharmaceutical Co., Ltd., under a
research license agreement to generate bispecific antibodies, including for indications in and outside oncology, which further underscore the
breadth of the Merus platform. We believe these collaborations, license and future agreements could potentially provide significant funding to
advance our pipeline and allow us to benefit from the additional resources, development and commercialization expertise of our collaborators.

Our Biclonics® and Triclonics® Candidate Portfolio
We currently have bispecific candidates in clinical development, with a variety bispecific and trispecific candidates in pre-clinical development. The
following table summarizes our development candidate pipeline:
There are also currently bispecific candidates in clinical development, which are subject to our collaboration and license agreements, for which we are
eligible to receive potential milestones and royalties, if approved:
Cancer Immunotherapeutics
Immunotherapy is a class of cancer treatment that works to harness a patient’s own immune system to attack the cancer cells. There are a number of
immunotherapies that are designed to engage various aspects of the immune system, for example: (1) adaptive immunity, specifically directing genetically
modified T cells to the tumor with chimeric antigen receptor, or CAR T cells or T-cell receptor modification; or modulating T-cell activity through co-
stimulation or checkpoint signals; and (2) innate immunity, including antibody-dependent cellular cytotoxicity (ADCC), cellular-dependent cytotoxicity
(CDC), monocyte/macrophage cytotoxicity, natural killer (NK) cell cytotoxicity, or other forms of T-cell cytotoxicity; all directed at the cancer cells. While
these therapies vary in mechanism of action, they rely on specific components of the innate or adaptive immune system to kill tumor cells or counteract
signals produced by cancer cells that suppress immune responses.
While these approaches have advanced the field of oncology, each also have limitations. For example, the enhanced ADCC of monoclonal antibodies that
bind to a single target expressed by tumor cells can potentially induce an autoimmune “on-target,
5
off-tumor” toxicity to normal non-tumor tissues that may also express the same target antigen. Cell-based therapies such as genetically modified CAR-T
cells can be difficult and expensive to manufacture, can persist in patients for many months, can be associated with a toxic cytokine release syndrome as
safety concerns, or can become ineffective if the tumor loses expression of the single antigen against which the CAR-T cells are directed. We believe
multispecific antibody candidates developed from our novel platforms offer the potential to overcome these limitations.
Background on Antibodies
The conventional antibody in full length immunoglobulin G (IgG) format is a Y-shaped molecule that consists of two identical heavy chains and two
identical light chains, as shown in the figure below. Each heavy chain pairs with the light chain to form two variable regions, or antigen binding fragment,
Fab, that bind to antigens, or targets, and a constant region, which includes a region known as the fragment crystallizable (Fc) that binds to receptors
present on effector cells in the immune system. In conventional full-length IgG, the variable regions are identical and bind to the same targets.
In multispecific antibodies, the two or more variable regions bind to two or more different targets. To achieve this in the full-length IgG format, different
heavy chain variable regions that can use a common light chain are combined. In addition, modifications of the heavy chain Fc regions are engineered to
drive the formation of full-length IgG that use two different heavy chains rather that two copies of the same heavy chain, which make a monospecific
antibody.
In both conventional monoclonal antibodies (mAbs) and IgG multispecific antibodies, the Fc region can bind to Fc receptors present on effector cells. This
binding results in the recruitment and activation of immune effector cells and amplifies the immune system’s response to antigens bound by the variable
region of the antibody. This process is called ADCC. The Fc region can be modified to enhance ADCC so as to generate a more potent immune response
against a particular target. The Fc region can also be silenced to block interactions with the immune system.
Our Biclonics® and Triclonics® Platforms
Our two technology platforms use large-scale functional screening in molecular and cell-based assays to identify novel, innovative Biclonics® and
Triclonics® with the specific characteristics desired for further development.
We believe our Biclonics® and Triclonics® platforms allow us to approach cancer treatment through multiple innovative modes of action:
•
•
Blocking oncogenic growth factor signaling by disrupting the signaling pathways that drive tumor cell growth or resistance to monoclonal
antibody therapy. This includes, for example tumor cell growth driven by NRG1 fusions interacting with the HER3 receptor. Hard-to-target
receptors that may drive tumor growth or escape can be targeted by our Dock and Block® mechanism whereby the binding a tumor associated
target prevalent on cancer cells facilitates a second domain to bind and block lesser expressed targets that are critical for cancer growth.
Engaging an adaptive immune response by recruiting T-cells and/or modulating co-stimulation or checkpoint inhibition. We can produce
multispecific antibodies that are designed to simultaneously bind to the T-cell antigen CD3 or
6
•
•
other effector cell engaging antigens, and/or tumor-associated targets, for a potentially potent T cell or other effector cell recruitment and
engagement to selectively kill tumor cells.
Engaging the innate immune response through multiple mechanisms. We can produce enhanced ADCC modifications in the Fc region of our
Biclonics® or Triclonics® designed to facilitate the recruitment of immune effector cells, such as natural killer cells, or NK cells, and
macrophages, to directly kill tumor cells. Specific binding domains engineered in multispecific antibodies can directly bind to macrophages
and monocytes; NK cells, each providing specific immune cell function to attack cancer cells.
Employing combinations of the above mechanisms. Using our platforms, we can design antibodies to simultaneously target a growth factor
receptor expressed by tumor cells and an immunomodulatory molecule involved in blocking and/or reactivating tumor-specific T cells.
Biclonics® and Triclonics® can be designed to target growth factor receptors, like epidermal growth factor receptors (EGFR) and HER2 that are
expressed on many tumors, while delivering an activation signal or checkpoint blockade to T cells.
Our process to select lead Biclonics® for clinical development is illustrated below. We use our patented MeMo®, Spleen to Screen®\, heterodimerization
technology, human antibody generation and production technologies to rapidly build large collections of Biclonics® or Triclonics® directed against
particular target combinations. We then test these collections in cell-based functional assays to identify multispecific antibodies that have the potential for
novel and innovative modes of action. We select the most potent or efficacious and evaluate them in multiple in vitro and in vivo assays to identify lead
candidates for clinical development.
Selection of Lead Multiclonics®
Our Biclonics® technology platform includes the following:
Human antibody generation. One of our platforms for generating human antibodies employs our patented transgenic common light chain technology,
which we refer to as MeMo®, harbors human heavy chain variable region gene segments and a human common light chain in its germline. MeMo®
harnesses the power of the in vivo immune system to yield human antibodies with the potential for high affinity, specificity, optimal biophysical
characteristics and low immunogenicity. Upon immunization, MeMo® is capable of generating large and diverse panels of human common light chain
antibodies against a broad variety of targets. These human common light chain antibodies are then used to generate large and diverse panels of human
multispecific antibodies capable of binding different targets of virtually any combination.
7
•
Patented dimerization technology and the full-length Immunoglobulin G format. Our Biclonics® consist of two different heavy chains that
need to stably form, or heterodimerize, inside a manufacturing cell line. Using our patented dimerization technology, we employ amino acid
residues with opposite charges in the CH3 domains of these heavy chains to efficiently drive the formation of the heterodimer bispecific
antibody rather than the homodimer antibody consisting of two copies of the same heavy chain. In addition, the use of a single, or common,
light chain in our human Biclonics® antibodies ensures that each heavy chain pairs with the correct, common light chain to efficiently form the
intended functional antigen binding regions. The combination of these approaches prevents the need for additional, more artificial techniques,
such as the use of linkers or chemical reactions, to force the pairing of different parts of the bispecific antibody. In addition, the format is
designed to retain favorable attributes of conventional human IgG mAbs, including their stability and predictability during manufacturing as
well as their long half-life and low immunogenicity during treatment of patients. The resulting Biclonics® are bispecific heterodimeric IgG
antibodies that are designed to closely mimic IgG antibodies that are produced naturally by the immune system.
The Biclonics® format also permits us to make modifications to the Fc region of the IgG antibody in order to enhance or limit effector functions associated
with this part of the molecule. This strategy has been successfully executed with conventional therapeutic mAbs. In order to enhance efficacy and promote
immunotherapeutic activity, we can use glycoengineered cell lines used in production to generate Biclonics® that are enhanced for ADCC, resulting in the
improved ability to recruit NK cells and macrophages. This ADCC enhancement has been made to our most advanced bispecific antibody candidate,
zenocutuzumab, our lead antibody candidate, MCLA-158 (petosemtamab) and to MCLA-129. In order to improve safety and tolerability, we can modify
our Biclonics® to prevent the excessive release of signaling proteins called cytokines, which can overstimulate the immune system. This process is called
Fc-silencing, and is designed to block the ability of our Biclonics® to bind to certain protein receptors on cells, known as Fc receptors, which are associated
with cytokine release. We utilize Fc silencing in the design of our bispecific antibody candidate MCLA-145.

High-throughput functional screening. We employ our patented Spleen to Screen® technology to rapidly screen panels of new target-specific
heavy chains that form common light chain binding domains, or we employ our already established panels of common light chain antibodies.
To date we have discovered over 10,000 unique common light chain antibodies directed at more than 40 different antigens, including tumor-
associated antigens such as EGFR and c-MET; T-cell binding, stimulating or co-stimulating proteins such as CD3 and CD137 (also called 4-
1BB); and other immune-cell engaging antigens. For example, we have an established panel of more than 175 unique and novel anti-CD3
common light chain antibodies from which to discover and develop the next generation of T-cell engaging bispecific and trispecific antibodies.
We then generate DNA constructs that encode target-specific human antibodies and express them in mammalian cells. The common light chain
format and proprietary dimerization modifications to the CH3 domain of the IgG promote the secretion of virtually pure Biclonics® into the
cell culture medium. The medium of thousands of cell cultures that each express a different Biclonics® is harvested and individually used in
high throughput molecular and cell-based functional assays to identify Biclonics® with specific novel characteristics for further development.
For example, the chart below shows the results of a pre-clinical study in which hundreds of different Biclonics® targeting HER2 and HER3 were
functionally screened for cell growth inhibition of tumor cell samples in the presence or absence of the HER3 ligand NRG1. Forty of the Biclonics®
depicted in the chart exhibited superior inhibition of cell growth compared to trastuzumab, a drug commonly prescribed for the treatment of breast cancer,
and were selected in the process leading to identification of zenocutuzumab.

Advantages of Biclonics®
We believe our Biclonics® technology platform provides the following advantages:
•
•
•
•
•
Rapid generation of human IgG antibodies having diversity at the heavy chain targeting an array of antigens, that are ready to be paired to
produce our Biclonics®, bispecific antibodies. Use of our patented MeMo®, Spleen to Screen®, heterodimerization and Fc modification
technologies, permits us to rapidly generate a large amount of diverse bispecific antibodies capable of targeting an array of antigen
combinations.
Biclonics® are stable, bispecific, full-length human IgG antibodies with no linkers or fusion proteins. Biclonics® retain the IgG format of
antibodies that are produced naturally by the immune system. Additionally, in contrast to many other bispecific antibody formats, Biclonics®
do not require linkers or modifications to force the correct pairing of heavy and light chain variable regions or exploit fusion proteins to add
functionality to the molecule. These qualities minimize time-consuming engineering efforts that can cause stability or developability obstacles,
and instead allow us to create Biclonics® with more predictable behavior during development.
Our Biclonics® technology platform allows for functional evaluation of Biclonics® in the relevant therapeutic format leading to the
discovery of therapeutic candidates with novel and innovative properties. Our Biclonics® technology platform permits rapid functional
screening of large collections of bispecific antibodies which allows us to identify lead candidates with multiple mechanisms of action that have
the potential to effectively kill tumor cells with high potency. This is an important step in the identification of lead bispecific antibody
candidates with functionalities that compare favorably against other forms of therapeutics, such as conventional mAbs as well as their
combinations.
Biclonics® preserve the stability, behavior and adaptability of normal IgG antibodies. Biclonics® are based on the robust and commonly used
IgG format to yield the favorable in vivo qualities associated with conventional mAbs, such as stability, long half-life and low immunogenicity.
As a result, our Biclonics® format provides attractive options for dosage schedules and methods of administration, rendering them compatible
with multiple modes of action for the efficient killing of tumor cells. Further, the IgG format allows us to apply previously established
technologies to further optimize our Biclonics® for therapeutic use.
Biclonics® can be reliably manufactured with high yields. Because our Biclonics® retain the IgG format of antibodies, our Biclonics® are
manufactured using the large-scale industry-standard processes that are also used for the production of conventional mAbs, and the yields of
Biclonics® we obtain are comparable to those of normal IgG antibodies. In stable cell lines, and using our IgG-based purification process can
result in up to greater than 98% purity for our Biclonics®.
Our Triclonics® Platform
Our Triclonics® technology is covered by existing Merus patents and pending patent applications. This format, and the suite of technologies that underpin
it, permit the development of therapeutic candidates designed to bind three targets with a single multivalent molecule. In pre-clinical studies and modeling,
Triclonics® have shown similar qualities of a natural IgG antibody, including favorable half-life, stability, low immunogenicity and favorable
developability characteristics. We believe Triclonics® have the potential to produce significant specificity and potency in tumor cell-killing activity and/or
to modulate the immune system to promote more robust anti-tumor immune responses, and have the potential for less on-target off-tumor toxicity. This
format allows us to leverage our proprietary genetically modified MeMo® mice, which as described above, harbor human heavy chain variable region gene
segments and a human common light chain in its germline, as well as the use of other means of antibody production. MeMo® harnesses the power of the in
vivo immune system to yield human antibodies with the potential for high affinity, specificity, optimal biophysical characteristics and low immunogenicity,
which can be combined into a single trispecific antibody produced with relative high purity. The Triclonics® platform employs our proprietary
technologies to produce large panels of substantially pure trispecific antibodies. In addition, we have engineered a panel of novel linkers that attach a third
binding domain to the antibody. This panel of linkers vary in properties such as length and flexibility, and are empirically selected for stability and other
drug-like properties, while remaining stable and are predicted to have low immunogenicity. The linker panel provides another lever of flexibility in
optimizing functional characteristics in our high-throughput screening while maintaining high quality, stability and limiting risk of immunogenicity.
9
One application of the Triclonics® platform is as a T-cell engager for solid tumors. By binding to three targets, we can generate Triclonics® designed to
specifically engage a combination of two tumor antigens for enhanced specificity, binding preferentially to tumor cells expressing both antigens, over
normal tissues that may express either antigen, but not both or both at lower expression levels. In this construct, the third binding domain can, for example,
engage an innate or adaptive immune effector cell protein, to stimulate killing of the tumor cell. We believe our Triclonics® platform will permit us to
develop molecules with enhanced on-target, on-tumor specificity, while optimally engaging the immune system mechanisms and potentially having greater
potency and a larger therapeutic window.
Our process to select lead Triclonics® leverages our patented MeMo® and Spleen to Screen® human antibody generation and heterodimerization
technologies, along with our proprietary linkers based on natural structures to undertake high throughput unbiased functional screening of Triclonics®.
With this approach, we have been able to evaluate thousands of different trispecific antibodies targeting three different antigens to identify those unique
combinations that pre-clinically have been observed to have desired characteristics for further development.
Our Bispecific and Trispecific Antibody Candidate Portfolio
We currently have four bispecific antibody candidates in clinical development, with additional bispecific and trispecific programs in pre-clinical
development.
Petosemtamab (MCLA-158, EGFR x LGR5 Biclonics®)
Petosemtamab is an investigational antibody-dependent cell-mediated cytotoxicity (ADCC)-enhanced Biclonics® for the potential treatment of solid
tumors that is designed to bind to cancer stem cells expressing EGFR and leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5). EGFR is a
member of the HER family of receptor tyrosine kinases and is important for growth and survival of cancer stem cells, including those with RAS mutations,
while LGR5 is a WNT target gene expressed in cancer cells with aberrations in the WNT signaling pathway and reported to be up regulated in a variety of
cancers including HNSCC, gastric cancer, NSCLC, colorectal cancer (CRC) and hepatocellular carcinoma (HCC). Petosemtamab is designed to exhibit
three independent
10
mechanisms of action including inhibition of EGFR-associated signaling, LGR5 binding leading to EGFR internalization and degradation in cancer cells,
and enhanced ADCC and antibody-dependent cellular phagocytosis (ADCP) activity.
Development
In our pre-clinical studies, petosemtamab demonstrated superior growth inhibition and selectivity versus the EGFR-targeting mAb, cetuximab.
Petosemtamab was significantly more potent than cetuximab in inhibiting the growth of patient-derived CRC organoids. Additionally, petosemtamab was
observed to be selectively more active in human tumor-derived organoids than in organoids derived from normal human colon. The activity of
petosemtamab on the tumor organoid size was more than 100 times greater than on the normal colon organoids. In contrast, the activity of cetuximab was
similar to the activity of petosemtamab on normal colon organoids and 20 to 100 times less than the activity of petosemtamab on tumor organoids. These
ex-vivo observations of petosemtamab with organoid models were further observed in vivo in xenograft models generated from the same patient-derived
organoids.
In our pre-clinical studies, petosemtamab further demonstrated significant induction of internalization of EGFR and LGR5, resulting in EGFR degradation,
and elicited potential anti-tumor activity in patient-derived esophageal, gastric and HNSCC xenograft models.

Solid Tumors
Petosemtamab is currently being evaluated in a phase 1/2 open-label, multicenter study, and is in the expansion phase, in patients with solid tumors,
including previously treated advanced HNSCC, and in combination with pembrolizumab, a PD-1blocking antibody, with untreated HNSCC expressing PD-
L1 (CPS > 1).
The recommended phase 2 dose was established at 1500 mg administered intravenously once every two weeks.
In April 2023, we presented interim clinical data as of a February 1, 2023 data cutoff, from the ongoing phase 1/2 trial of petosemtamab in previously
treated HNSCC at the American Association of Cancer Research (AACR) Annual Meeting 2023, in Orlando, Florida. As of the February 1, 2023 data
cutoff date, 49 previously treated HNSCC patients (pts) were treated with petosemtamab at the recommended phase 2 dose of 1500 mg intravenously every
two weeks. 43 pts were evaluable for efficacy, receiving ≥2 treatment cycles (≥8 weeks) with ≥1 post-baseline tumor assessment or experiencing early
progressive disease. Overall responses rate (ORR) in the 43 evaluable pts was 37.2% (16/43; 95% CI 23%-53.3%) by RECIST 1.1. per investigator
assessment, including 15 confirmed partial responses (PRs) and 1 confirmed complete response (CR) (ongoing after 20 months). Disease control rate
(DCR) (CR + PR + stable disease) was 72.1% (31/43; 95% CI 56.3%-84.7%). Median time to response was 1.8 months (range 0.8-3.5). Median duration of
response was 6.0 months (95% CI 3.7-NC), with 10 of 16 (62.5%) responders ongoing, and 12 of 43 (27.9%) patients overall ongoing at the time of the
data cutoff. Median progression free survival was 5.3 months (95% CI 3.7-6.8); with 29 of 43 pts progressing and 14 of 43 pts censored. Median overall
survival was 11.5 months (95% CI 7.2-20.6); with 29 of 49 pts still alive at the data cutoff date. We plan to provide updated efficacy, durability and safety
data of this cohort in the second half of 2024.
In the 80 pts treated with 1500 mg petosemtamab every two weeks across dose escalation and expansion cohorts of the study, petosemtamab continued to
demonstrate a manageable safety profile. Gastrointestinal and skin toxicities were mostly mild to moderate and no treatment-related Grade 5 adverse events
(AEs) were observed as of the data cutoff date. The most frequent related AEs were signs and symptoms of infusion-related reactions (IRRs): 74% Grade
1-4, 21% Grade 3-4 (as grouped term), mainly occurred during first infusion, and 6 of 80 pts discontinued on Day 1 due to a Grade 3-4 IRR. For all patients
rechallenged after an IRR, rechallenge was successful. IRRs were manageable with prophylaxis/prolonged infusion (necessary on Day 1 only).
13
We are currently evaluating a cohort of patients receiving petosemtamab in combination with pembrolizumab, a PD-1 blocking antibody, in untreated
HNSCC expressing PD-L1 (CPS > 1) to evaluate safety and clinical activity in this population. We believe initial safety data from this single arm cohort
may support the initiation of a first-line registration trial with this combination. We plan to report initial interim clinical data from this cohort in the second
quarter of 2024. Among the initial patients dosed in the first-line combination, the safety profile of the combination has been observed to be generally well
tolerated.
We are currently evaluating approximately 40 patients in previously treated (2L/3L) HNSCC with petosemtamab monotherapy at the 1100 or 1500 mg dose
levels to confirm a suitable dose for future potential randomized trials. We plan to share clinical data from this cohort in the second half of 2024. Based on
these data and additional information and analyses, we anticipate potentially initiating a randomized phase 3 trial of petosemtamab monotherapy, or
investigators’ choice of single agent chemotherapy or cetuximab in 2L/3L HNSCC. We anticipate such a trial could potentially start in mid-2024. We
believe a randomized registration trial in HNSCC with an overall response rate endpoint could potentially support accelerated approval and the overall
survival results from the same study could potentially verify its clinical benefit to support regulatory approval.
The FDA has granted Fast Track Designation for the investigation of petosemtamab for the treatment of patients with recurrent or metastatic HNSCC
whose disease has progressed following treatment with platinum-based chemotherapy and an anti-programmed cell death protein 1 (anti-PD-1) antibody.
Fast Track is a designation designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill unmet medical needs.
In 2024, we also plan to evaluate petosemtamab in 2L colorectal cancer patients.
Zenocutuzumab (Zeno, MCLA-128, HER2 x HER3 Biclonics®)
Zeno is an antibody-dependent cell-mediated cytotoxicity (ADCC)-enhanced Biclonics® that utilizes Merus’ Dock & Block® mechanism to bind to HER2,
and bind to and disrupt the interaction between HER3 and ligand, neuregulin (NRG1) or mutated form NRG1 fusion, in solid tumors. HER2, or human
epidermal growth factor receptor 2, is amplified in many solid tumors and is associated with poor prognosis, and the activation of HER3, or human
epidermal growth factor receptor 3, is associated with tumor progression and treatment resistance. On the surface of tumor cells, HER2 pairs, or dimerizes,
with HER3, and the resulting pair drives malignant progression of HER2-expressing cancer cells. NRG1, which is the ligand for HER3, causes cancer cells
to grow and become resistant to treatment with HER2-targeted therapies. Zeno is believed to target the HER3 signaling pathway by disrupting the
interaction of HER3 with its ligand NRG1 and to overcome the resistance of tumor cells to HER2-targeted therapies using two mechanisms: blocking
growth and survival pathways to stop tumor expansion and recruitment, and ADCC-enhanced elimination of the tumor via effector cells. In addition, we
have identified a rare, genetically defined patient population whose cancers harbor NRG1 fusions. The NRG1 gene encodes for neuregulin, the ligand for
HER3. Fusions between NRG1 and other genes in the genome are rare genetic events occurring in solid tumors, and are associated with activation of
HER2/HER3 signaling and growth of cancer cells. The NRG1 fusion is a powerful driver of cancer cell growth. We believe that pre-clinical studies and
clinical evaluation indicate Zeno
14
(binding to HER2 and blocking NRG1 fusion protein interaction with HER3) has the potential to be particularly effective against tumors harboring NRG1
fusions.
Development
In our pre-clinical studies, the administration of Zeno resulted in the inhibition of NRG-induced growth in cultures of cancer cells. Zeno also blocked
activation of two key signaling pathways for the growth and survival of tumor cells more than Herceptin (trastuzumab) or the combination of Herceptin and
Perjeta (pertuzumab) (shown in red below) or experimental anti-HER3 mAbs (shown in green below). See Geuijen et al. Cancer Cell (2018).
* indicates analog antibodies.
In a patient-derived tumor xenograft mouse model (PDX model), Zeno significantly blocked tumor growth of a cancer containing an NRG1 gene fusion.
15
Based on encouraging pre-clinical results, we initiated a phase 1/2 study of Zeno in solid tumors.
•
NRG1 Fusions and other potential cancers through targeting HER2 and HER3
We continue to enroll patients in the phase 1/2 eNRGy trial to assess the safety and anti-tumor activity of Zeno monotherapy in NRG1+ cancers.
We presented a clinical update on Zeno in NRG1+ cancer from the phase 1/2 eNRGy trial and Early Access Program (EAP) at ESMO 2023 held in Madrid,
Spain on October 20-24, 2023. The presentations consisted of a mini-oral lecture titled: Durable efficacy of zenocutuzumab, a HER2 x HER3 bispecific
antibody, in advanced NRG1 fusion-positive (NRG1+) non-small cell lung cancer (NSCLC) and a poster presentation titled: Durable efficacy of
zenocutuzumab, a HER2 x HER3 bispecific antibody in advanced NRG1 fusion-positive (NRG1+) pancreatic ductal adenocarcinoma (PDAC). As of the
July 31, 2023 data cutoff date, 105 patients with NRG1+ NSCLC were treated with Zeno. 78 patients with measurable disease were treated by February 13,
2023, allowing for the potential for ≥ 24 weeks follow-up, and who met the criteria for the primary analysis population. In 78 evaluable patients the overall
response rate (ORR) was 37.2% (29/78; 95% Cl: 26.5-48.9) per RECIST v1.1 by investigator assessment, 61.5% (95% CI: 49.8 - 72.3) clinical benefit
rate, 14.9 months median duration of response (DOR) and 20 patients were continuing treatment as of the data cutoff.
16
As of the July 31, 2023 data cutoff date, 44 patients with NRG1+ PDAC were treated with Zeno. 33 patients with measurable disease were treated
by February 13, 2023, allowing for the potential for ≥ 24 weeks follow-up, and who met the criteria for the primary analysis population. In the 33 evaluable
patients the ORR was 42.4% (95% CI, 25.5–60.8) per RECIST v1.1 by investigator assessment; 1 (3%) patient achieved a complete response, and 13 (39%)
patients achieved a partial response. 72.7% (95% CI, 54-87) clinical benefit rate, 82% experienced tumor reduction and 9.1 months (95% CI, 5.5–12.0)
median DOR; and 6 patients were continuing treatment as of the data cutoff. Of 27 evaluable patients for CA 19-9 values, 21 patients, (78%) showed a ≥
50% decrease in CA 19-9 values from baseline. Zeno demonstrated a well-tolerated safety profile among the 189 NRG1+ cancer patients who were treated
with Zeno 750 mg every two weeks monotherapy, with 6% of patients experiencing related grade 3-4 toxicities.
17
In July 2020, Zeno was granted orphan drug designation by the FDA for the treatment of pancreatic cancer and in January 2021, we announced that Zeno
received Fast Track Designation for the treatment of patients with metastatic solid tumors harboring NRG1 gene fusions that have progressed on standard-
of-care therapy.
In June and July 2023, we announced that the FDA has granted BTD to Zeno for the treatment of patients with advanced unresectable or metastatic NRG1+
pancreatic cancer following progression with prior systemic therapy or who have no satisfactory alternative treatment options. Additionally, the FDA has
granted BTD to Zeno for the treatment of patients with advanced unresectable or metastatic NRG1+ NSCLC, following progression with prior systemic
therapy.
We expect we will have sufficient clinical data in the first half of 2024 to support potential Biologics License Application submissions in both NRG1+
NSCLC and NRG1+ PDAC.
We believe that obtaining a commercialization partnership agreement will be an essential step in bringing Zeno to patients with NRG1+ cancer, if
approved.
We are also evaluating Zeno in combination with an ADT (enzalutamide or abiraterone) in CRPC, irrespective of NRG1+ status. Enrollment has been
paused and we plan to continue monitoring these patients. We are also continuing to monitor patients treated with Zeno in combination with afatinib in
NRG1+ NSCLC, but no further enrollment is planned at this time.
We are also conducting ongoing translational work on potential biomarkers outside of NRG1+ cancer which may support development opportunities for
Zeno in additional areas of unmet need.
MCLA-129 (EGFR x c-MET Biclonics®)
MCLA-129 is an investigational Biclonics®, designed to bind EGFR and c-MET, for the potential treatment of solid tumors. EGFR is an important
oncogenic driver in many cancers. The upregulation of c-MET signaling has been associated with resistance to EGFR inhibition. MCLA-129 has two
distinct mechanisms of action. First, MCLA-129 is designed to block the signaling of EGFR as well as c-MET, in an effort to inhibit tumor growth and
survival. Second, MCLA-129 utilizes ADCC-enhancement technology, which is designed for greater cell-killing potential.
MCLA-129 is being developed in collaboration with Betta Pharmaceuticals Co. Ltd. (Betta). Under the terms of the collaboration, Betta is responsible for
the clinical development and commercialization of MCLA-129, if approved, in China and we retain all rights
18
to MCLA-129 outside of China. In January 2021, Betta announced that the Chinese National Medical Products Administration had accepted its
Investigational New Drug application (IND) for MCLA-129 injection and in October 2021, Betta announced that the first patient was dosed in Betta’s
sponsored phase 1/2 trial of MCLA-129 in China in patients with advanced solid tumors.
Development
Pre-clinical data on MCLA-129 were presented in October 2019, at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer
Therapeutics. The poster, entitled “Pre-clinical evaluation of MCLA-129: a bispecific antibody targeting c-MET and EGFR,” showed that MCLA-129
inhibited and reversed resistance to tyrosine kinase resistant NSCLC, cell lines resulting in tumor growth inhibition in xenograft models of NSCLC. In
these xenograft models, MCLA-129 showed tumor shrinkage in mice whose tumors are resistant to the EGFR small molecule inhibitor erlotinib.
MCLA-129 Inhibited TKI Resistant NSCLC
| MCLA-129 Reversed Acquired TKI Resistance
We believe these pre-clinical data suggest MCLA-129, if successfully developed and approved, could benefit patients having NSCLC that become resistant
to EGFR targeted therapies.
•
Solid Tumors
We are developing MCLA-129 as a potential treatment for solid tumors, including NSCLC. We presented a clinical update on MCLA-129 from ongoing
expansion cohorts in NSCLC and in previously head and neck squamous cell carcinoma (HNSCC) at the European Society of Medical Oncology (ESMO)
Asia Congress 2023.
The reported data are from three expansion cohorts in the open label trial evaluating MCLA-129 in combination with osimertinib, a third generation EGFR
TKI, in treatment-naïve EGFR mutant (m) NSCLC (1L) and in EGFRm NSCLC that has progressed on osimertinib (2L+), as well as MCLA-129
monotherapy in previously treated HNSCC. As of an August 10, 2023 data cutoff date, 60 patients(pts) with advanced/metastatic EGFRm NSCLC were
treated (16/1L, 44/2L+). In the 1L setting, 16 pts were treated, with all pts evaluable for response. All 16 pts experienced tumor shrinkage. 9 confirmed
partial responses (PRs) and 3 unconfirmed PRs were observed (12/16, 75%; 95% CI 48-93) by RECIST v1.1. per investigator assessment; 11 responses
were ongoing, including the 3 unconfirmed PRs, 94% disease control rate (DCR) (95% CI 70-100), 5.1 months (range 0.5-8.5) median duration of
exposure with 81% continuing treatment.
•
•
In the 2L+ setting, 44 pts were treated, with 34 pts evaluable for response. All received prior osimertinib in the 1L/2L setting, 50% as only
prior therapy; 36% received prior chemotherapy. 11 confirmed PRs and 1 unconfirmed PR were observed (12/34, 35%; 95% CI 20-54) by
RECIST v1.1. per investigator assessment, 9 responses were ongoing as of the data cutoff date, including the 1 unconfirmed PR, 74% DCR
(95% CI 56-87) and 2.8 months (range: 0.3-11.5) median duration of exposure with 39% continuing treatment.
Early safety assessment in 60 NSCLC pts treated with MCLA-129 plus osimertinib included: most common adverse events (AEs) regardless
of causality were infusion related reactions (IRRs; composite term) in 87% (12% ≥ grade(G) 3, treatment emergent adverse events (TEAEs)
led to discontinuations in 14 (23%) pts, treatment related interstitial lung disease (ILD)/pneumonitis in 13 pts (22%), four were G1, two were
G2, four were G3, and three were G5, and venous thromboembolic events (VTEs) in 23%; 5% treatment related.
19
In EGFRm NSCLC, with the strong clinical activity for MCLA-129 shown in the interim data, we are encouraged by the potential for MCLA-129 in the
treatment of lung cancer and beyond. We have identified focused investment opportunities. We continue to follow patients with EGFRm NSCLC treated
with MCLA-129 in combination with osimertinib, to evaluate potential for biomarkers as a means to maximize efficacy, while proactively addressing
safety signals seen to date.
Additionally, we remain interested and are continuing investigation of cohort B evaluating MCLA-129 in patients with MET exon14 skipping NSCLC.
We also remain interested in exploring partnering MCLA-129 with other companies to sufficiently resource the development of MCLA-129 and potential
benefit it may have for patients.
We plan to start a cohort of MCLA-129 in combination with chemotherapy in 2L+ EGFRm NSCLC in 2024.
MCLA-145 (CD137 x PD-L1 Biclonics®)
MCLA-145 is a Biclonics® T-cell engager that binds to human programmed death-ligand 1 (PD-L1) and CD137. MCLA-145 is designed to recruit,
activate and prevent the exhaustion of tumor-infiltrating T cells, and to cause a potent and durable T-cell activation in the tumor microenvironment. MCLA-
145’s binding to a cell is predicted to lead to clustering of CD137 on T cells when PD-L1 is expressed on adjacent cells, and block the T-cell inhibitory PD-
1/PD-L1 interactions in the tumor. Developed by Merus through an unbiased functional screening of multiple immunomodulatory target combinations, the
unique immunostimulatory profile of MCLA-145 derives from the potential to potently activate immune effector cells in the context of the tumor
microenvironment while blocking inhibitory signals among T-cells within the same immune cell population.
Development
In our pre-clinical studies, MCLA-145 showed binding to PD-L1 and CD137, recruitment of T cells into the tumor, blocking of inhibitory PD-1/PD-L1 axis
and potent T-cell activation.
20
Further, MCLA-145 demonstrated superior tumor cell killing as compared to the administration of a combination of monospecific anti-PD-L1 and anti-
CD137 antibodies in PDX models.
•
Solid Tumors
MCLA-145 is currently in a global, phase 1, open-label, single-agent clinical trial evaluating MCLA-145 in combination with pembrolizumab, PD-1
blocking antibody.
In May 2019, we commenced a phase 1 open-label, single-agent clinical trial of MCLA-145, consisting of dose escalation followed by dose expansion, for
the potential treatment of patients with advanced solid tumors. The primary objectives of the phase 1 trial are dose finding and evaluation of safety and
tolerability in patients. The trial will also examine potential preliminary antitumor activity and functional target engagement of single-agent MCLA-145.
In December 2021, we presented interim clinical data on MCLA-145 from the phase 1 trial in patients with solid tumors at the ESMO Immuno-Oncology
Congress 2021. As of the data cutoff date of July 14, 2021, 34 patients with advanced or metastatic solid tumors with median age of 60.5 (range 27-81)
years had been treated at 8 dose levels ranging from 0.4-75mg Q2W. The median (range) duration of treatment with MCLA 145 was approximately 6 (1–
74) weeks. Reported AEs were generally managed with drug interruption and/or administration of steroids in some patients. TEAEs occurred in 33 patients
(97.1%) and treatment-related TEAEs
21
occurred in 23 patients (67.6%), most commonly fatigue (n=6, 17.6%) and decreased neutrophil count (n=6, 17.6%). Dose limiting toxicities (DLTs),
defined as within 28 days from the first infusion, occurred in 4 patients (11.8%).
Laboratory alanine transaminase/aspartate transaminase (ALT/AST) elevations of any grade were observed in 15 patients (44.1%), with grade ≥3 ALT/AST
elevations in 6 patients (17.6%). Preliminary evidence of antitumor activity has been observed at doses ≥25 mg biweekly. Analysis of peripheral blood
showed robust T-cell activation, including activation of cytotoxic CD8+ cells and cytokines, across the 10 to 75 mg biweekly dosing range.
Pre-clinical Discovery Programs
We intend to further leverage our Biclonics® and Triclonics® technology platforms to identify multiple additional antibody candidates and advance them to
clinical development. Each of these antibody candidates are designed to bind to targets believed to be useful in the treatment of cancer with an intention to
establish efficacy and obtain information for submission to the FDA. Using our patented platforms, we will continue to evaluate new targets and
combinations to identify potential candidates with the highest therapeutic potential and select those candidates to be advanced into clinical trials.
Collaboration Agreements
As part of our business strategy, we collaborate with a range of partners, including pharmaceutical, biotechnology, and diagnostic companies, as well as
academic institutions. We intend to continue to seek collaborations and license agreements to develop and commercialize therapeutics in order to exploit
the potential of our Biclonics® and Triclonics® platforms.
Incyte Corporation
We have entered into a collaboration and license agreement (Collaboration Agreement) with Incyte Corporation (Incyte). Under the terms of the
Collaboration Agreement, we and Incyte have agreed to collaborate with respect to the research, discovery and development of monospecific or bispecific
antibodies utilizing our proprietary Biclonics® technology platform. Following the election by Incyte to opt-out of its ex-U.S. development of MCLA-145,
discussed below, the collaboration encompasses up to 10 independent programs.
We have the option to co-fund development of products, if any, arising from one specified program, and subject to certain conditions, to a second specified
program, in each case in exchange for a share of profits in the United States, as well as the right to participate in a specified proportion of detailing
activities in the United States for one of such programs. If we exercise our co-funding option for a program, we would be responsible for funding 35% of
the associated future global development costs and, for certain of such programs, would be responsible for reimbursing Incyte for certain development
costs incurred prior to the option exercise. All products as to which we have exercised our option to co-fund development would be subject to joint
development plans and overseen by a joint development committee, with Incyte having final determination as to such plans in cases of dispute.
For one of our current clinical programs, concerning MCLA-145, under the Collaboration Agreement, Incyte had received the exclusive right to develop
and commercialize the product candidate outside the United States. In January 2022, we announced that Incyte elected to opt-out of its ex-U.S.
development of MCLA-145, restoring full global rights to Merus. Under the terms of the Collaboration Agreement, Incyte supported the program for a
limited time while ex-U.S. activities transitioned to Merus. Incyte retains a right to a residual royalty of up to 4% on sales of future commercialization of
MCLA-145, if approved.
22
For each program, where we have not elected to co-fund development or where we do not have such a co-funding option and which has not been dropped
or terminated by Incyte, Incyte is solely responsible for all costs of global development and commercialization activities. We retain the rights to, among
other things, our Biclonics® technology platform as well as clinical and pre-clinical candidates and future programs emerging from our platform that are
outside the scope of the Collaboration Agreement.
In January 2017, upon the Collaboration Agreement becoming effective, Incyte made an upfront non-refundable payment to us of $120 million for the
rights granted under the Collaboration Agreement. For each program as to which we do not have commercialization or co-development rights, we are
eligible to receive up to $100 million in future contingent development and regulatory milestones and up to $250 million in commercialization milestones,
as well as tiered royalties ranging from 6% to 10% of global net sales. For each program as to which we have exercised our option to co-fund development,
we are eligible to receive a 50% share of profits (or sustain 50% of any losses) in the United States and tiered royalties ranging from 6% to 10% of net sales
of products outside of the United States. If we opt to cease co-funding a program as to which we exercised our co-development option, then we will no
longer receive a share of profits in the United States but will be eligible to receive the same milestones from the co-funding termination date and the same
tiered royalties described above with respect to non-co-developed programs and, depending on the stage at which we choose to cease co-funding
development costs, additional royalties ranging up to 4% of net sales in the United States.
The Collaboration Agreement will continue on a program-by-program basis until neither party has any royalty payment obligations with respect to such
program or, if earlier, the termination of the Collaboration Agreement or any program in accordance with the terms of the Collaboration Agreement. The
Collaboration Agreement may be terminated in its entirety, or on a program-by-program basis, by Incyte for convenience. The Collaboration Agreement
may also be terminated by either party under certain other circumstances, including material breach, or on a program-by-program basis for patent challenge
of patents under the applicable program, in each case as set forth in the Collaboration Agreement. If the Collaboration Agreement is terminated in its
entirety or with respect to one or more programs, all rights in the terminated programs revert to us, subject to payment to Incyte of a reverse royalty of up to
4% on sales of future products, if we elect to pursue development and commercialization of products arising from the terminated programs.
In connection with the Collaboration Agreement, we entered into a Share Subscription Agreement with Incyte, pursuant to which, in January 2017, we
issued and sold to Incyte 3,200,000 common shares for an aggregate purchase price of $80.0 million.
Eli Lilly and Company (Eli Lilly)
In 2021, we entered into a collaboration and license agreement (the Lilly Collaboration Agreement) and share subscription agreement (the “Lilly
Subscription Agreement”) with Eli Lilly and Company, an Indiana corporation (Eli Lilly).
Under the terms of the Lilly Collaboration Agreement, we and Eli Lilly agreed to collaborate with respect to the discovery and research of bispecific
antibodies utilizing our proprietary Biclonics® bispecific technology platform. The collaboration encompasses up to three (3) independent programs
directed to the generation of T-cell re-directing bispecific antibodies that bind CD3 and a tumor associated antigen target selected by Eli Lilly (Target) to be
the subject of each such program.
We granted to Eli Lilly an exclusive, worldwide, royalty-bearing, sublicensable license, under certain patent rights and know-how to exploit certain
compounds and products directed to designated Targets in combination with CD3, or directed to such designated Target(s) alone as a monospecific
antibody or monospecific antibody drug conjugate, subject to rights granted by us to third parties under one or more existing third-party agreements. We
also retain all rights not granted to Eli Lilly.
Additionally, in the case of a change of control that may adversely impact certain rights and obligations of us and Eli Lilly under the Lilly Collaboration
Agreement, (a) we have agreed to terminate or transfer its rights to third parties under certain research programs and (b) Eli Lilly has the option to take over
certain of our research obligations.
Eli Lilly paid an upfront, non-refundable payment of $40 million for the rights granted under the Lilly Collaboration Agreement. Eli Lilly agreed to fund
the research and development activities we conduct for each program under an agreed research plan and budget. With respect to each product arising from
each program, we are eligible to receive up to $290 million in future contingent development and regulatory milestones and up to $250 million in
commercial sales milestones, for a total of up to approximately $1.6 billion for a single product generated from all three programs. We are further eligible
to receive, on a product-by-product and country-by-country basis, tiered royalties based on the level of worldwide aggregate annual net sales at percentages
ranging from the mid-single digits to low double digits until the royalty term expires.
The Lilly Collaboration Agreement includes a three-year research term for us to perform research and development activities, subject to two extension
terms of six months at Eli Lilly’s discretion. The Lilly Collaboration Agreement will continue on a product-by-product basis until Eli Lilly has no royalty
payment obligations with respect to such product or, if earlier, the termination of the Lilly Collaboration Agreement or any program in accordance with the
terms of the Lilly Collaboration Agreement. The Lilly Collaboration Agreement may be terminated in its entirety or on a program-by-program basis at will
by Eli Lilly. The Lilly Collaboration Agreement may also be terminated by either us or Eli Lilly under certain other circumstances, including material
breach, as set forth in the Lilly Collaboration Agreement. If the Lilly Collaboration Agreement is terminated with respect to one or more programs,
depending on the stage of development, certain rights in the terminated programs revert to us, in accordance with the terms of the Lilly Collaboration
Agreement.
23
Also in January 2021, in connection with entering into the Lilly Collaboration Agreement, pursuant to the Lilly Subscription Agreement, Eli Lilly agreed to
purchase 706,834 common shares of the Company at a price per share of $28.295 for aggregate gross proceeds to us of approximately $20 million (the
“Private Placement”).
Ono Pharmaceutical Co., Ltd.
In April 2014, we entered into a strategic research and license agreement with Ono, under which we granted Ono an exclusive, worldwide, royalty-bearing
license to research, test, make, use and market a limited set of bispecific antibody candidates, if approved, based on our Biclonics® technology platform,
directed to two undisclosed targets.
Ono paid us a non-refundable upfront fee of €1.0 million, and we are eligible to receive up to an aggregate of €57.0 million in milestone payments upon
achievement of specified research and clinical development milestones. For products commercialized under this agreement, if any, we are also eligible to
receive a mid-single digit royalty on net sales. For a designated period, which may include limited time periods following termination of this agreement, in
certain circumstances we and our affiliates are prohibited from researching, developing or commercializing bispecific antibodies against the target
combination that are the subject of this agreement. Ono also provides funding for our research and development activities under an agreed-upon plan. This
research and license agreement will expire after all milestone payments have been received and all related patent rights have expired, unless terminated
earlier. Ono has the right to terminate this agreement at any time for any reason, with or without cause. The licenses granted to Ono may convert to royalty-
free, fully-paid, perpetual licenses if Ono terminates the agreement for uncured material breach. We retain all rights to use and commercialize any
antibodies directed to one target utilized under the collaborative research program, and any antibodies directed to the second target developed under the
collaborative research program, excluding the up to five lead and/or selected antibodies against the second target Ono is pursuing, provided that the use and
commercialization is not with respect to the particular target combination. To date, we have achieved five of the specified milestones under this research
and license agreement and have received an aggregate of €4.7 million in milestone payments.
On March 14, 2018, we entered into a second contract research and license agreement with Ono. Pursuant to an exclusive option granted to Ono in the prior
agreement executed in April 2014, Ono exercised its option to enter into the March 2018 agreement. We granted Ono an exclusive, worldwide, royalty-
bearing license, with the right to sublicense, research, test, make, use and market bispecific antibody candidates based on our Biclonics® technology
platform against two undisclosed targets directed to a particular undisclosed target combination. Ono identifies and selects the licensed bispecific
antibodies for which it is responsible for conducting further non-clinical and clinical development activities for such licensed bispecific antibodies and
pharmaceutical products containing such antibodies, including manufacture and process development. Ono controls and has exclusive rights over the
worldwide commercialization of any approved products, including worldwide supply, and is solely responsible for all costs and expenses related to
commercialization. Ono has agreed to fund our research and development activities and be responsible for the payment of all costs and expenses for its own
research and development activities, which are set out in a mutually agreed upon research plan. We retain all rights to use and commercialize any
antibodies that are generated under the collaborative research program, excluding the up to five lead and/or selected antibodies against the targets Ono is
pursuing, provided that the use and commercialization is not with respect to the particular target combination.
As part of the 2018 agreement, Ono agreed to pay an upfront non-refundable payment of €0.7 million for the rights granted and we are also eligible to
receive an additional aggregate of €57.0 million in milestone payments upon achievement of specified research and clinical development milestones. In the
fourth quarter of 2022, Merus achieved a milestone payment of €1.0 million from Ono for preclinical advancement of a lead candidate arising from this
license. To date, we have achieved four of the specified pre-clinical milestones under this research and license agreement and have received an aggregate of
€2.7 million in milestone payments. For products commercialized under the License Agreement, if any, the Company is eligible to receive a mid-single
digit royalty on net sales.
For a designated period, which may include limited time periods following termination of this agreement, in certain circumstances we are prohibited from
researching, developing or commercializing bispecific antibodies against the undisclosed target combination that are the subject of this agreement. Ono
also provides funding for our research and development activities under an agreed-upon plan. This research and license agreement will expire after all
milestone payments have been received and all related patent rights have expired, unless terminated earlier. Ono has the right to terminate this agreement at
any time for any reason, with or without cause. The licenses granted to Ono may convert to royalty-free, fully-paid, perpetual licenses if Ono terminates the
agreement for uncured material breach.
Betta Pharmaceuticals Co. Ltd.
On December 10, 2018, we entered into a collaboration and license agreement with Betta Pharmaceuticals Co. Ltd. (Betta) where we granted Betta an
exclusive license to develop and commercialize MCLA-129 in China. We retain all rights outside of China. Under the terms of the agreement, Betta
retained a contract manufacturing organization with experience in filing IND applications with U.S. authorities and clinical trial applications (CTAs) with
European regulatory authorities in order to produce clinical trial materials for the Chinese market and the rest of the world.
24
In addition to a non-refundable upfront payment, we and Betta will share equally the cost of the transfer of the manufacturing technology to a contract
manufacturing organization. We are also eligible to receive an aggregate of $12.0 million in milestone payments contingent upon Betta achieving certain
specified development and commercial goals as well as tiered royalty payments of net sales of any products resulting from the collaboration in China. Betta
is eligible to receive milestone payments contingent upon us achieving certain specified development and commercial goals, and is eligible to receive tiered
royalty payments of net sales outside of China.
Manufacturing
Our Biclonics® technology platform relies on third parties for manufacturing our product candidates. We rely on and expect to continue to rely on third-
party contract manufacturing organizations (CMOs) for the supply of current good manufacturing practice-grade (cGMP-grade) clinical trial materials and
commercial quantities of our antibody candidates and products, if approved. We currently do not have any agreements for the commercial production of
product candidates, but we have contracted several biopharmaceutical CMOs for the clinical manufacture of zenocutuzumab, MCLA-158 or petosemtamab,
MCLA-129 and MCLA-145. We believe that the standardized Biclonics® manufacturing process can be transferred to additional CMOs and potential
future co-development or co-commercialization collaborations or partnerships for the production of clinical and commercial supplies of our Biclonics® in
the ordinary course of business.
Sales and Marketing
We have not yet defined our sales, marketing or product distribution strategy for zenocutuzumab, petosemtamab, MCLA-129, MCLA-145 or any of our
other antibody candidates. We hired an Executive Vice President & Chief Commercial Officer in February 2022, to lead the commercial strategy for
Merus’ pipeline of multispecific product candidates in development. We believe that obtaining a commercialization partnership agreement will be an
essential step in bringing zenocutuzumab to patients with NRG1+ cancer, if approved. Our commercial strategy may include the use of strategic partners,
distributors, a contract sales force, or the establishment of our own commercial infrastructure. We plan to further evaluate these alternatives as we approach
approval, if any, for one of our antibody candidates.
Competition
We compete directly with companies that focus on oncology and companies dedicating their resources to cancer therapies. We also face competition from
academic research institutions, governmental agencies and other various public and private research institutions. With the proliferation of new drugs and
therapies into oncology, we expect to face increasingly intense competition as new technologies become available and new therapeutic candidates are
clinically developed or approved therapies are explored for new indications. Any antibody candidates that we successfully develop and commercialize will
compete with existing therapies and new therapies that may become available in the future.
Many of our competitors have significantly greater financial, manufacturing, marketing, drug development, technical and human resources than we do.
Mergers and acquisitions in the pharmaceutical, biotechnology and diagnostic industries may result in even more resources being concentrated among a
smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative
arrangements with large and established companies. These competitors also compete with us in recruiting and retaining top qualified scientific and
management personnel and establishing clinical trial sites and patient registration for clinical trials, manufacturer’s production capacity, as well as in
acquiring technologies complementary to, or necessary for, our programs.
The key competitive factors affecting the success of all of our therapeutic antibody candidates, if approved, are likely to be their efficacy, safety, dosing
convenience, price, the effectiveness of companion diagnostics in guiding the use of related therapeutics, the level of generic competition and the
availability of reimbursement from government and other third-party payors.
Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, less
expensive, more convenient or easier to administer, or have fewer or less severe side effects than any products that we may develop. Our competitors also
may obtain FDA or other regulatory 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 our antibody candidates achieve marketing approval, they may be
priced at a significant premium over competitive products if any have been approved by then.
In addition to currently marketed therapies, there are also a number of products in late-stage clinical development to treat cancer, including other bispecific
antibodies or similar molecules. Our closest competitors in this area include Genmab A/S, Inhibrx, Inc., Janssen Pharmaceutical Companies, MacroGenics,
Inc., Regeneron Pharmaceuticals, Inc., Bicara Therapeutics, Exelixis, Inc., and Xencor, Inc. The antibody candidates in development by competitors may
provide efficacy, safety, dosing convenience and other benefits that are not provided by currently marketed therapies. As a result, they may provide
significant competition for any of our antibody candidates for which we obtain marketing approval.

We plan to continue to expand our intellectual property estate by filing patent applications directed to dosage forms, methods of treatment and additional
compositions created or identified from our Biclonics® and Triclonics® technology platforms, improvements to those platforms and our ongoing
development of our antibody candidates. Specifically, we seek patent protection in the United States and internationally for novel compositions of matter
directed to aspects of the molecules, basic structures and processes for manufacturing these molecules and the use of these molecules in a variety of
therapies, in combinations, dosages, methods of treatments, among other features.
Our patent portfolio is intended to cover, but is not limited to, the composition of matter of our bispecific antibody candidates, their methods of use, the
Biclonics® and Triclonics® technology platforms used to generate them, related technologies and/or other aspects of the inventions that are important to
our business, including our MeMo® mouse, and common light chain generation platforms and techniques, Spleen to Screen® technology, and recombinant
host cells capable of producing our antibody candidates, methods of purification, and heterodimerization, among other proprietary technology. We also rely
on trademarks, trade secrets and careful monitoring of our proprietary information to protect aspects of our business that are not amenable to, or that we do
not consider appropriate for, patent protection.
We also rely on know-how, continuing technological innovation and in-licensing opportunities to develop, strengthen, and maintain our proprietary
positions.
Our success will depend on our ability to obtain and maintain patent and other proprietary protection for commercially important technology, inventions
and know-how related to our business, defend and enforce our patents, maintain our licenses to use intellectual property owned by third parties, preserve
the confidentiality of our trade secrets and operate without infringing valid and enforceable patents and other proprietary rights of third parties. For
important factors related to our proprietary technology, inventions, improvements, platforms and antibody candidates, please see the section entitled “Risk
Factors—Risks Related to Intellectual Property and Information Technology.”
Government Regulation
We are subject to extensive regulation. We expect our antibody candidates to be regulated as biologics. Biological products are subject to regulation under
the Federal Food, Drug, and Cosmetic Act (FD&C Act) and the Public Health Service Act (PHS Act) and other federal, state, local and foreign statutes and
regulations. Both the FD&C Act and the PHS Act and their corresponding regulations govern, among other things, the testing, manufacturing, safety,
efficacy, labeling, packaging, storage, record keeping, distribution, reporting, advertising and other promotional practices involving biological products.
U.S. Biological Products Development Process
The process required by the FDA before a biologic may be marketed in the United States generally involves the following:
•
•
•
•
•
•
•
•
completion of extensive nonclinical, sometimes referred to as pre-clinical laboratory tests, and pre-clinical animal trials and applicable
requirements for the humane use of laboratory animals and formulation studies in accordance with applicable regulations, including good
laboratory practices (GLPs);
submission to the FDA of an IND, which must become effective before human clinical trials may begin;
approval by an institutional review board (IRB) or ethics committee at each clinical site before the trial is commenced;
performance of adequate and well-controlled human clinical trials according to the FDA’s regulations, commonly referred to as good clinical
practice (GCP), regulations and any additional requirements for the protection of human research subjects and their health information, to
establish the safety and efficacy of the proposed biological product for its intended use;
submission to the FDA of a Biologics License Application (BLA) that includes substantive evidence of safety, purity, and potency from results
of nonclinical testing and clinical trials;
satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the biological product is produced to assess
compliance with current Good Manufacturing Practice (cGMP) requirements to assure that the facilities, methods and controls are adequate to
preserve the biological product’s identity, strength, quality and purity;
potential FDA audit of certain nonclinical and clinical trial sites that generated the data in support of the BLA; and
FDA review and approval, or licensure, of the BLA.
28
Before testing any antibody candidate in humans, the antibody candidate enters the pre-clinical testing stage. Pre-clinical tests, also referred to as
nonclinical trials, generally include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential
safety and activity of the antibody candidate. The conduct of certain pre-clinical tests must comply with federal regulations and requirements including
GLPs.
The clinical trial sponsor must submit the results of the pre-clinical tests, together with manufacturing information, analytical data, any available clinical
data or literature and a proposed clinical protocol, to the FDA as part of the IND. Some pre-clinical testing may continue even after the IND is submitted.
The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA places the clinical trial on a clinical hold within that 30-day
time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may also
impose clinical holds, at any time before or during clinical trials due to safety concerns or non-compliance. If the FDA imposes a clinical hold, trials may
not recommence without FDA authorization and then only under terms authorized by the FDA.
Clinical trials involve the administration of the biological antibody candidate to healthy volunteers or patients under the supervision of qualified
investigators, generally physicians not employed by or under the trial sponsor’s control. Clinical trials are conducted under protocols detailing, among other
things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject
safety, including stopping rules that assure a clinical trial will be stopped if certain adverse events should occur. Each protocol and any amendments to the
protocol must be submitted to the FDA as part of the IND. While the IND is active, progress reports summarizing the results of the clinical trials and
nonclinical studies performed since the last progress report, among other information, must be submitted at least annually to the FDA, and written IND
safety reports must be submitted to the FDA and investigators for serious and unexpected suspected adverse events, findings from other studies suggesting
a significant risk to humans exposed to the same or similar drugs, findings from animal or in vitro testing suggesting a significant risk to humans, and any
clinically important increased incidence of a serious suspected adverse reaction compared to that listed in the protocol or investigator brochure.
Clinical trials must be conducted and monitored in accordance with the FDA’s regulations comprising the GCP requirements, including the requirement
that all research subjects provide informed consent. Further, each clinical trial must be reviewed and approved by an independent IRB at or servicing each
institution at which the clinical trial will be conducted. An IRB is charged with protecting the welfare and rights of trial participants and considers such
items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also
approves the form and content of the informed consent that must be signed by each clinical trial subject or his or her legal representative and must monitor
the clinical trial until completed. There are also requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public
registries.
Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:
•
•
•
Phase 1. The biological antibody candidate is initially introduced into healthy human subjects and tested for safety. In the case of some
products for severe or life-threatening diseases, especially when the product may be too inherently toxic to ethically administer to healthy
volunteers, the initial human testing is often conducted in patients.
Phase 2. The biological antibody candidate is evaluated in 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, optimal dosage and dosing
schedule.
Phase 3. The biological antibody candidate is further evaluated for dosage, clinical efficacy, potency, and safety in an expanded patient
population at geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the
product and provide an adequate basis for product labeling.
In some cases, the FDA may require, or sponsors may voluntarily pursue, additional clinical trials after a product is approved to gain more information
about the product. In addition, the FDA may require post marketing clinical trials, sometimes referred to as phase 4 clinical trials, designed to further assess
a biological product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of approved products that have been
commercialized. These so-called phase 4 studies may also be made a condition to approval of the BLA.
Concurrent with clinical trials, companies usually complete additional animal trials and must also develop additional information about the physical
characteristics of the biological antibody candidate as well as finalize a process for manufacturing the product in commercial quantities in accordance with
cGMP requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHS Act emphasizes the
importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently
producing quality batches of the biological antibody candidate and, among other things, the sponsor must develop methods for testing the identity, strength,
quality, potency and purity of the final biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be
conducted to demonstrate that the biological antibody candidate does not undergo unacceptable deterioration over its shelf life.
29
U.S. Review and Approval Processes
After the completion of clinical trials of a biological antibody candidate, FDA approval of a BLA must be obtained before commercial marketing of the
biological product. The BLA must include results of product development, laboratory and animal trials, human trials, information on the manufacture and
composition of the product, proposed labeling and other relevant information. In addition, under the Pediatric Research Equity Act (PREA) a BLA or
supplement to a BLA must contain data to assess the safety and effectiveness of the biological antibody candidate 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. A sponsor
who is planning to submit a marketing application for a drug or biological product that includes a new active ingredient, new indication, new dosage form,
new dosing regimen or new route of administration must submit an initial Pediatric Study Plan within sixty days after an end-of-phase 2 meeting or as may
be agreed between the sponsor and FDA. Unless otherwise required by regulation, PREA does not apply to any biological product for an indication for
which orphan designation has been granted.
Under the Prescription Drug User Fee Act (PDUFA), as amended, each BLA must be accompanied by a user fee. The FDA adjusts the PDUFA user fees on
an annual basis. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a
small business. Additionally, no user fees are assessed on BLAs for products designated as orphan drugs, unless the product also includes a non-orphan
indication.
Within 60 days following submission of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before the agency
accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request
additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is 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 of the BLA. The FDA’s goal
is to review standard applications within ten months after the filing date, or, if the application qualifies for priority review, six months after the FDA
accepts the application for filing. In both standard and priority reviews, the review process may also be extended by FDA requests for additional
information or clarification.
The FDA reviews the BLA to determine, among other things, whether the proposed product is safe, pure and potent, and whether the product is being
manufactured in accordance with cGMP requirements to assure and preserve the product’s identity, safety, strength, quality, potency and purity. The FDA
may refer applications for novel biological products or biological products that present difficult questions of safety or efficacy to an advisory committee,
typically a panel that includes clinicians and other experts, for review, evaluation and 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. During the biological product approval process, the FDA also will determine whether a Risk Evaluation and Mitigation Strategy
(REMS) is necessary to assure the safe use of the biological antibody candidate. If the FDA concludes a REMS is needed, the sponsor of the BLA must
submit a proposed REMS; the FDA will not approve the BLA without a REMS, if required.
Before approving a BLA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the product 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 a BLA, the FDA will typically inspect one or more clinical sites to assure that the
clinical trials were conducted in compliance with IND trial requirements and GCP requirements.
Notwithstanding the submission of relevant data and information, the FDA may ultimately decide that the BLA does not satisfy its regulatory criteria for
approval and deny approval. If the FDA decides not to approve the BLA in its present form, the FDA will issue a complete response letter that usually
describes all of the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling
changes, or major, for example, requiring additional clinical trials. Additionally, the complete response letter may include recommended actions that the
applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the BLA,
addressing all of the deficiencies identified in the letter, or withdraw the application.
If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may
otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or
precautions be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the
form of a REMS, or otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to as
phase 4 clinical trials, designed to further assess a biological product’s safety and effectiveness, and testing and surveillance programs to monitor the safety
of approved products that have been commercialized.
30
Orphan Drug Designation
The FDA may grant orphan drug designation (or orphan designation) to drugs intended to treat a rare disease or condition that affects fewer than 200,000
individuals in the United States, or if it affects more than 200,000 individuals in the United States, there is no reasonable expectation that the cost of
developing and marketing the drug for this type of disease or condition will be recovered from sales in the United States. Orphan designation must be
requested before submitting a BLA. After the FDA grants orphan designation, the identity of the therapeutic agent and its potential orphan use are disclosed
publicly by the FDA. Orphan designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.
In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax
advantages and user-fee waivers. In addition, if a product receives the first FDA approval for the disease or condition for which it has orphan designation,
the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same
disease or condition for a period of seven years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan
exclusivity or where the manufacturer with orphan exclusivity is unable to assure sufficient quantities of the approved orphan designated product.
Competitors, however, may receive approval of different products for the disease or condition for which the orphan drug or product has exclusivity or
obtain approval for the same product but for a different disease or condition for which the orphan drug or product has exclusivity. If a drug or biological
product has an orphan designation it receives marketing approval for a disease or condition broader than what is designated, it may not be entitled to orphan
exclusivity.
Expedited Development and Review Programs
The FDA offers a number of expedited development and review programs for qualifying product candidates. For example, the FDA has a Fast Track
program that is intended to expedite or facilitate the process for reviewing investigational biological products that meet certain criteria. Specifically,
biological product candidates are eligible for Fast Track designation if they are intended to treat a serious or life-threatening disease or condition and
demonstrate the potential to address unmet medical needs for such diseases or conditions. Fast Track designation applies to the combination of the product
and the specific indication for which it is being studied. The sponsor of a Fast Track product candidate has opportunities for more frequent interactions with
the applicable FDA review team during product development and, once a BLA is submitted, the application may be eligible for priority review. With regard
to a Fast Track product, the FDA may consider for review sections of the marketing application on a rolling basis before the complete application is
submitted, if the sponsor provides a schedule for the submission of the sections of the application, the FDA agrees to accept sections of the application and
determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the application.
A product candidate intended to treat a serious or life-threatening disease or condition may also be eligible for Breakthrough Therapy designation to
expedite its development and review. The criteria for breakthrough therapy designation require preliminary clinical evidence that demonstrates the drug
may have substantial improvement on at least one clinically significant endpoint over available therapy. The designation includes all of the Fast Track
program features, as well as more intensive FDA interaction and guidance beginning as early as phase 1 and an organizational commitment to expedite the
development and review of the product candidate, including involvement of senior managers.
Any marketing application for a biologic product candidate submitted to the FDA for approval, including a product candidate with a Fast Track designation
and/or Breakthrough Therapy designation, may be eligible for other types of FDA programs intended to expedite the FDA review and approval process. A
BLA is eligible for priority review if a product candidate is intended to treat a serious disease or condition, if approved, would provide a significant
improvement in safety or effectiveness compared to marketed products. The FDA will attempt to direct additional resources to the evaluation of an
application for a new biological product designated for priority review in an effort to facilitate the review. Additionally, depending on the design of the
applicable clinical trials, a product candidate may be eligible for accelerated approval. Biological products studied for their safety and effectiveness in
treating serious or life-threatening illnesses and that provide meaningful advantages over existing treatments may be eligible for accelerated approval,
which means that they may be approved on the basis of adequate and well-controlled clinical trials supporting a determination that the product has an effect
on a surrogate endpoint or an intermediate clinical endpoint that is reasonably likely to predict a clinical benefit, or on the basis of an effect on a clinical
endpoint other than survival or 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. As a condition of approval, the FDA generally requires that a sponsor of a biological product
subject to accelerated approval perform adequate and well-controlled confirmatory clinical trials to verify and describe the anticipated clinical benefit, and
may require that such confirmatory trials be underway prior to granting accelerated approval. Biological products receiving accelerated approval may be
subject to expedited withdrawal procedures if the sponsor fails to conduct the required confirmatory clinical trials in a timely manner or if such trials fail to
verify the predicted clinical benefit. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials,
which could adversely impact the timing of the commercial launch of the product.
31
Fast Track designation, priority review and Breakthrough Therapy designation do not change the standards for approval but may expedite the development
or approval process. Even if we receive one of these designations for our antibody candidates, the FDA may later decide that our antibody candidates no
longer meet the conditions for qualification. In addition, these designations may not provide us with a material commercial advantage.
Post-Approval Requirements
Maintaining substantial compliance with applicable federal, state, and local statutes and regulations requires the expenditure of substantial time and
financial resources. Rigorous and extensive FDA regulation of biological products continues after approval, particularly with respect to cGMP
requirements. Manufacturers of approved biologics are required to comply with applicable requirements in the cGMP regulations, including quality control
and quality assurance and maintenance of records and documentation. Other post-approval requirements applicable to biological products include record-
keeping requirements, reporting of adverse effects, and reporting updated safety and efficacy information.
Biological product manufacturers and other entities involved in the manufacture and distribution of approved biological products are required to register
their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for
compliance with cGMP requirements and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production
and quality control to maintain cGMP compliance. In addition, changes to the manufacturing process or facility generally require prior FDA approval
before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also
subject to further FDA review and approval.
The FDA may withdraw 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 studies to assess new safety risks; or imposition of distribution restrictions 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 product recalls;
fines, warning letters, or untitled letters;
clinical holds on clinical studies;
refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of product approvals;
product seizure or detention, or refusal to permit the import or export of products;
consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs;
mandated modification of promotional materials and labeling and the issuance of corrective information;
the issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing warnings or other safety
information about the product; or
injunctions or the imposition of civil or criminal penalties.
The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. A company can make only those claims that are 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. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential
civil and criminal penalties. Physicians may prescribe legally available products for uses that are not described in the product’s labeling and that differ from
those tested and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the
best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA
does, however, restrict a manufacturer’s communications on the subject of off-label use of their products.
Biosimilars and Exclusivity
The Biologics Price Competition and Innovation Act of 2009 (BPCIA) created an abbreviated approval pathway for biological products that are biosimilar
to or interchangeable with an FDA-licensed reference biological product.
Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety,
purity, and potency, can be shown through analytical studies, animal studies, and a clinical trial or studies. Interchangeability requires that a product is
biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in
any given patient and, for products that are administered
32
multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without
increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic.
Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product
was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on
which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the
reference product if the FDA approves a full BLA for the competing product containing the sponsor’s own pre-clinical data and data from adequate and
well-controlled clinical trials to demonstrate the safety, purity and potency of their product. The BPCIA also created certain exclusivity periods for
biosimilars approved as interchangeable products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be
readily substituted by pharmacies, which are governed by state pharmacy law.
A biological product can also obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing
exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted
based on the voluntary completion of a pediatric trial in accordance with an FDA-issued “Written Request” for such a trial. The issuance of a written
request does not obligate the sponsor to complete the requested trials.
FDA Regulation of Companion Diagnostics
We expect that our antibody candidates may require use of an in vitro diagnostic to identify appropriate patient populations for our products. These
diagnostics, often referred to as companion diagnostics, are regulated as medical devices. In the United States, the United States Federal Food, Drug and
Cosmetics Act (FD&C Act) and its implementing regulations, and other federal and state statutes and regulations govern, among other things, medical
device design and development, pre-clinical and clinical testing, premarket clearance or approval, registration and listing, manufacturing, labeling, storage,
advertising and promotion, sales and distribution, export and import, and post-market surveillance. Unless an exemption applies, diagnostic tests require
marketing clearance or approval from the FDA prior to commercial distribution. The two primary types of FDA marketing authorization applicable to a
medical device are premarket notification, also called 510(k) clearance, and premarket approval (PMA) approval. We expect that any companion diagnostic
developed for use with our antibody candidates may utilize the PMA pathway.
If use of a companion diagnostic is essential to safe and effective use of a drug or biologic product, then the FDA generally will require approval or
clearance of the diagnostic contemporaneously with the approval of the therapeutic product. On August 6, 2014, the FDA issued a final guidance document
addressing the development and approval process for “In Vitro Companion Diagnostic Devices.” According to the guidance, for novel candidates such as
our antibody candidates, a companion diagnostic device and its corresponding drug or biologic candidate may be required to be approved or cleared
contemporaneously by the FDA for the use indicated in the therapeutic product labeling, although the FDA may decide that it is appropriate to approve a
therapeutic product even though a companion diagnostic device is not approved or cleared contemporaneously. In general, the FDA expects that a
companion diagnostic that is intended for use with the therapeutic product will be later approved or cleared through an appropriate submission and the
therapeutic product labeling will be revised to stipulate the use of the companion diagnostic. The guidance also explains that a companion diagnostic device
used to make treatment decisions in clinical trials of a drug generally will be considered an investigational device, unless it is employed for an intended use
for which the device is already approved or cleared. If used to make critical treatment decisions, such as patient selection, the diagnostic device generally
will be considered a significant risk device under the FDA’s Investigational Device Exemption (IDE) regulations. Thus, the sponsor of the diagnostic
device will be required to comply with the IDE regulations. According to the guidance, if a diagnostic device and a drug are to be studied together to
support their respective approvals, both products can be studied in the same investigational study, if the study meets both the requirements of the IDE
regulations and the IND regulations. The guidance provides that depending on the details of the study plan and subjects, a sponsor may seek to submit an
IND alone, or both an IND and an IDE. In July 2016, the FDA issued a draft guidance document intended to further assist sponsors of therapeutic products
and sponsors of in vitro companion diagnostic devices on issues related to co-development of these products, and in April 2020, the FDA issued final
guidance describing considerations for the development and labeling of in vitro companion diagnostic devices to support the indicated uses of multiple
drug or biological oncology products.
The FDA generally requires companion diagnostics intended to select the patients who will respond to cancer treatment to obtain approval of a PMA for
that diagnostic contemporaneously with approval of the therapeutic. The review of these in vitro companion diagnostics in conjunction with the review of a
cancer therapeutic involves coordination of review by the FDA’s Center for Biologics Evaluation and Research and by the FDA’s Center for Devices and
Radiological Health. The PMA process, including the gathering of clinical and pre-clinical data and the submission to and review by the FDA, can take
several years or longer. It involves a rigorous premarket review during which the applicant must prepare and provide the FDA with reasonable assurance of
the device’s safety and effectiveness and information about the device and its components regarding, among other things, device design, manufacturing and
labeling. PMA applications are subject to an application fee. In addition, PMAs for certain devices must generally include the results from extensive pre-
clinical and adequate and well-controlled clinical trials to establish the safety and effectiveness of the device for each indication for which FDA approval is
sought. In particular, for a diagnostic, the applicant must demonstrate that the diagnostic produces reproducible results when the same sample is tested
multiple times by multiple users at multiple laboratories. As part of the
33
PMA review, the FDA will typically inspect the manufacturer’s facilities for compliance with the Quality System Regulation (QSR) which imposes
elaborate testing, control, documentation and other quality assurance requirements.
If the FDA evaluations of both the PMA application and the manufacturing facilities are favorable, the FDA will either issue an approval letter or an
approvable letter, which usually contains a number of conditions that must be met in order to secure the final approval of the PMA, such as changes in
labeling, or specific additional information, such as submission of final labeling, in order to secure final approval of the PMA. If the FDA concludes that
the applicable criteria have been met, the FDA will issue a PMA for the approved indications, which can be more limited than those originally sought by
the applicant. The PMA can include post-approval conditions that the FDA believes necessary to ensure the safety and effectiveness of the device,
including, among other things, restrictions on labeling, promotion, sale and distribution.
If the FDA’s evaluation of the PMA or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue a not approvable letter. A
not approvable letter will outline the deficiencies in the application and, where practical, will identify what is necessary to make the PMA approvable. The
FDA may also determine that additional clinical trials are necessary, in which case the PMA approval may be delayed for several months or years while the
trials are conducted and then the data is submitted in an amendment to the PMA. Once granted, PMA approval may be withdrawn by the FDA if
compliance with post approval requirements, conditions of approval or other regulatory standards is not maintained or problems are identified following
initial marketing. PMA approval is not guaranteed, and the FDA may ultimately respond to a PMA submission with a not approvable determination based
on deficiencies in the application and require additional clinical trials or other data that may be expensive and time-consuming to generate and that can
substantially delay approval.
After a device is placed on the market, it remains subject to significant regulatory requirements. Medical devices may be marketed only for the uses and
indications for which they are cleared or approved. Device manufacturers must also establish registration and device listings with the FDA. A medical
device manufacturer’s manufacturing processes and those of its suppliers are required to comply with the applicable portions of the QSR, which cover the
methods and documentation of the design, testing, production, processes, controls, quality assurance, labeling, packaging and shipping of medical devices.
Domestic facility records and manufacturing processes are subject to periodic unscheduled inspections by the FDA. The FDA also may inspect foreign
facilities that export products to the United States.
Government Regulation Outside of the United States
In addition to regulations in the United States, we are subject to a variety of regulations in other jurisdictions governing, among other things, clinical trials
and any commercial sales and distribution of our products. Because biologically sourced raw materials are subject to unique contamination risks, their use
may be restricted in some countries. In addition, ethical, social and legal concerns about gene-editing technology, gene therapy, genetic testing and genetic
research could result in additional regulations restricting or prohibiting the processes we may use.
Whether or not we obtain FDA approval for a product, we must 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. The requirements and process governing the conduct of clinical trials,
product licensing, pricing and reimbursement vary from country to country. If we fail to comply with applicable foreign regulatory requirements, we may
be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and
criminal prosecution.
Non-Clinical Studies and Clinical Trials
Similarly to the U.S., the various phases of non-clinical and clinical research in the European Union (EU) are subject to significant regulatory controls.
Non-clinical (pharmaco-toxicological) studies are performed to demonstrate the health or environmental safety of new chemical or biological substances.
Non-clinical studies must be conducted in compliance with the principles of good laboratory practice, or GLP, as set forth in EU Directive 2004/10/EC
(unless otherwise justified for certain particular medicinal products, e.g., radio-pharmaceutical precursors for radio-labeling purposes). In particular, non-
clinical studies, both in vitro and in vivo, must be planned, performed, monitored, recorded, reported and archived in accordance with the GLP principles,
which define a set of rules and criteria for a quality system for the organizational process and the conditions for non-clinical studies. These GLP standards
reflect the Organization for Economic Co-operation and Development requirements.
Clinical trials of medicinal products in the EU must be conducted in accordance with EU and national regulations and the International Council for on
Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH), guidelines on Good Clinical Practices (GCP) as well as the
applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.
34
The regulatory landscape related to clinical trials in the EU has been subject to recent changes. The EU Clinical Trials Regulation (CTR) which was
adopted in April 2014 and repeals the EU Clinical Trials Directive, became applicable on January 31, 2022. Unlike directives, the CTR is directly
applicable in all EU member states without the need for member states to further implement it into national law. The CTR notably harmonizes the
assessment and supervision processes for clinical trials throughout the EU via a Clinical Trials Information System, which contains a centralized EU portal
and database.
While the EU Clinical Trials Directive required a separate clinical trial application (CTA) to be submitted in each member state in which the clinical trial
takes place, to both the competent national health authority and an independent ethics committee, much like the FDA and IRB respectively, the CTR
introduces a centralized process and only requires the submission of a single application to all member states concerned. The CTR allows sponsors to make
a single submission to both the competent authority and an ethics committee in each member state, leading to a single decision per member state. The CTA
must include, among other things, a copy of the trial protocol and an investigational medicinal product dossier containing information about the
manufacture and quality of the medicinal product under investigation. The assessment procedure of the CTA has been harmonized as well, including a joint
assessment by all member states concerned, and a separate assessment by each member state with respect to specific requirements related to its own
territory, including ethics rules. Each member state’s decision is communicated to the sponsor via the centralized EU portal. Once the CTA is approved,
clinical study development may proceed.
The CTR foresees a three-year transition period. The extent to which ongoing and new clinical trials will be governed by the CTR varies. Clinical trials for
which an application was submitted (i) prior to January 31, 2022 under the Clinical Trials Directive, or (ii) between January 31, 2022 and January 31, 2023
and for which the sponsor has opted for the application of the Clinical Trials Directive remain governed by said Directive until January 31, 2025. After this
date, all clinical trials (including those which are ongoing) will become subject to the provisions of the CTR.
Medicines used in clinical trials must be manufactured in accordance with Good Manufacturing Practices (GMP). Other national and European Union-wide
regulatory requirements may also apply.
During the development of a medicinal product, the European Medicines Agency (EMA) and national regulators provide the opportunity for dialogue and
guidance on the development program. At the EMA level, this is usually done in the form of scientific advice, which is given by the Scientific Advice
Working Party of the Committee for Medicinal Products for Human Use (CHMP). A fee is incurred with each scientific advice procedure. Advice from the
EMA is typically provided based on questions concerning, for example, quality (chemistry, manufacturing and controls testing), nonclinical testing and
clinical trials, and pharmacovigilance plans and risk-management programs. Advice is not legally binding with regard to any future marketing
authorization application of the product concerned.
Marketing Authorizations
In the EU, medicinal products can only be placed on the market after obtaining a marketing authorization (MA). To obtain regulatory approval of an
investigational biological product in the EEA, we must submit a marketing authorization application (MAA). The process for doing this depends, among
other things, on the nature of the medicinal product.
The centralized procedure results in a single MA, issued by the European Commission, based on the opinion of the Committee for Medicinal Products for
Human Use, or CHMP, of the EMA which is valid across the entire territory of the EU. The centralized procedure is compulsory for certain human drugs
that are: (i) derived from biotechnology processes, such as genetic engineering, (ii) contain a new active substance indicated for the treatment of certain
diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative diseases, autoimmune and other immune dysfunctions and viral diseases, (iii) designated
orphan medicines and (iv) advanced-therapy medicinal products, such as gene therapy, somatic cell therapy or tissue-engineered medicines. The centralized
procedure may at the request of the applicant also be used in certain other cases and in particular for any other products containing new active substances
not authorized in the EU or for product candidates which constitute a significant therapeutic, scientific, or technical innovation or for which the granting of
authorization would be in the interests of public health in the EU.
Under the centralized procedure, the maximum timeframe for the evaluation of a MAA by the EMA is 210 days. This excludes so-called clock stops,
during which additional written or oral information is to be provided by the applicant in response to questions asked by the CHMP. At the end of the review
period, the CHMP provides an opinion to the European Commission. If this opinion is favorable, the Commission may then adopt a decision to grant an
MA.
MAs have an initial duration of five years. After these five years, the authorization may be renewed on the basis of a reevaluation of the risk-benefit
balance. Once renewed, the MA is valid for an unlimited period unless the European Commission or the competent authority of the EU member states
decides, on justified grounds relating to pharmacovigilance, to proceed with one additional five-year renewal.
Under the centralized procedure and in exceptional cases, the CHMP might perform an accelerated review of an MAA in no more than 150 days (not
including clock stops). Innovative products that target an unmet medical need and are expected to be of major public health interest may be eligible for a
number of expedited development and review programs, such as the PRIME scheme, which
35
provides incentives similar to the breakthrough therapy designation in the U.S. PRIME is a voluntary scheme aimed at enhancing the EMA’s support for the
development of medicines that target unmet medical needs. It is based on increased interaction and early dialogue with companies developing promising
medicines, to optimize their product development plans and speed up their evaluation to help them reach patients earlier. Product developers that benefit
from PRIME designation can expect to be eligible for accelerated assessment but this is however not guaranteed. The benefits of a PRIME designation
includes the appointment of a rapporteur from the CHMP before submission of an MAA, early dialogue and scientific advice at key development
milestones, and the potential to qualify products for accelerated review earlier in the application process.
Data and Marketing Exclusivity
The EU also provides opportunities for market exclusivity. For example, in the EU, upon receiving MA, reference medicinal products generally receive
eight years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity period prevents generic or biosimilar
applicants from relying on the pre-clinical and clinical trial data contained in the dossier of the reference product when applying for a generic or biosimilar
MA in the EU during a period of eight years from the date on which the reference product was first authorized in the EU. The market exclusivity period
prevents a successful generic or biosimilar applicant from commercializing its product in the EU until 10 years have elapsed from the initial MA of the
reference product in the EU. The overall ten-year market exclusivity period may be extended to a maximum of eleven years if, during the first eight years a
new therapeutic indication with significant clinical benefit over existing therapies is approved. However, there is no guarantee that a product will be
considered by the EU’s regulatory authorities to be a new chemical entity, and products may not qualify for data exclusivity.
There is a special regime for biosimilars, or biological medicinal products that are similar to a reference medicinal product but that do not meet the
definition of a generic medicinal product, for example, because of differences in raw materials or manufacturing processes. For such products, the results of
appropriate preclinical or clinical trials must be provided, and guidelines from the EMA detail the type of quantity of supplementary data to be provided for
different types of biological product. There are no such guidelines for complex biological products, such as gene or cell therapy medicinal products, and so
it is unlikely that biosimilars of those products will currently be approved in the EU. However, guidance from the EMA states that they will be considered
in the future in light of the scientific knowledge and regulatory experience gained at the time.
Orphan Medicinal Products
The criteria for designating an “orphan medicinal product” in the EU are similar in principle to those in the United States. A medicinal product may be
designated as orphan if its sponsor can establish that: (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 EU when the application is made, or (b) the product,
without the benefits derived from orphan status, would not generate sufficient return in the EU to justify investment; and (3) there exists no satisfactory
method of diagnosis, prevention or treatment of such condition authorized for marketing in the EU, or if such a method exists, the product will be of
significant benefit to those affected by the condition. Orphan medicinal products are eligible for financial incentives such as reduction of fees or fee
waivers, protocol assistance, and access to the centralized procedure. Upon grant of a MA, orphan medicinal products are entitled to a ten-year period of
market exclusivity for the approved therapeutic indication, which means that during this period, the regulatory authorities cannot accept another application
for a MA, or grant a MA or accept an application to extend an existing MA for the same indication, in respect of a similar medicinal product for a period of
ten years. The period of market exclusivity is extended by two years for orphan medicinal products that have also complied with an agreed pediatric
investigation plan. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications. The
application for orphan designation must be submitted before the MAA. The applicant will receive a fee reduction for the MAA if the orphan designation
has been granted, but not if the designation is still pending at the time the MA is submitted. Orphan designation does not convey any advantage in, or
shorten the duration of, the regulatory review and approval process.
The 10-year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for
orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity or where the prevalence of the
condition has increased above the threshold. Additionally, MA 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 enough orphan medicinal product.
Post-Approval Requirements
Similar to the United States, both MA holders and manufacturers of medicinal products are subject to comprehensive regulatory oversight by the EMA, the
European Commission and/or the competent regulatory authorities of the member states. The holder of a MA must establish and maintain a
pharmacovigilance system and appoint an individual qualified person for pharmacovigilance
36
(QPPV) who is responsible for the establishment and maintenance of that system, and oversees the safety profiles of medicinal products and any emerging
safety concerns. Key obligations include expedited reporting of suspected serious adverse reactions and submission of periodic safety update reports, or
PSURs.
All new MAAs must include a risk management plan (RMP) describing the risk management system that the company will put in place and documenting
measures to prevent or minimize the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the
MA. Such risk-minimization measures or post-authorization obligations may include additional safety monitoring, more frequent submission of PSURs, or
the conduct of additional clinical trials or post-authorization safety studies.
The advertising and promotion of medicinal products is also subject to laws concerning promotion of medicinal products, interactions with physicians,
misleading and comparative advertising and unfair commercial practices. All advertising and promotional activities for the product must be consistent with
the approved summary of product characteristics, and therefore all off-label promotion is prohibited. Direct-to-consumer advertising of prescription
medicines is also prohibited in the EU. Although general requirements for advertising and promotion of medicinal products are established under EU
directives, the details are governed by regulations in each Member State and can differ from one country to another.
Failure to comply with EU and member state laws that apply to the conduct of clinical trials, manufacturing approval, MA of medicinal products and
marketing of such products, both before and after grant of the MA, manufacturing of pharmaceutical products, statutory health insurance, bribery and anti-
corruption or with other applicable regulatory requirements may result in administrative, civil or criminal penalties. These penalties could include delays or
refusal to authorize the conduct of clinical trials or to grant MA, product withdrawals and recalls, product seizures, suspension, withdrawal or variation of
the MA, total or partial suspension of production, distribution, manufacturing or clinical trials, operating restrictions, injunctions, suspension of licenses,
fines and criminal penalties.
The aforementioned EU rules are generally applicable in the European Economic Area (EEA) which consists of the 27 EU member states plus Norway,
Liechtenstein and Iceland.
For other countries outside of the EU, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical trials,
product licensing, pricing and reimbursement vary from country to country. In all cases, again, the clinical trials are conducted in accordance with GCP and
the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.
If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of
regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.
Regulation of Companion Diagnostics
In the EU, in vitro diagnostic medical devices were regulated by Directive 98/79/EC which regulated the placing on the market, the CE-marking, the
essential requirements, the conformity assessment procedures, the registration obligations for manufactures and devices as well as the vigilance procedure.
In vitro diagnostic medical devices had to comply with the requirements provided for in the Directive, and with further requirements implemented at
national level (as the case may be).
The regulation of companion diagnostics is subject to further requirements since the in vitro diagnostic devices Regulation (No 2017/746) (IVDR) became
applicable on May 26, 2022. However, on October 14, 2021, the European Commission proposed a “progressive” roll-out of the IVDR to prevent
disruption in the supply of in vitro diagnostic medical devices. The European Parliament and Council adopted the proposed Regulation on December 15,
2021. The IVDR fully applies as of May 26, 2022 but there is a tiered system extending the grace period for many devices (depending on their risk
classification) before they have to be fully compliant with the Regulation. The IVDR which introduces a new classification system for companion
diagnostics which are now specifically defined as diagnostic tests that support the safe and effective use of a specific medicinal product, by identifying
patients that are suitable or unsuitable for treatment. Companion diagnostics will have to undergo a conformity assessment by a notified body. Before it can
issue an EU certificate, the notified body must seek a scientific opinion from the EMA on the suitability of the companion diagnostic to the medicinal
product concerned if the medicinal product falls exclusively within the scope of the centralized procedure for the authorization of medicines, or the
medicinal product is already authorized through the centralized procedure, or a MA application for the medicinal product has been submitted through the
centralized procedure. For other substances, the notified body can seek the opinion from a national Competent Authorities or the EMA.
The aforementioned EU rules are generally applicable in the EEA.
37
Other Healthcare Laws
In addition to FDA restrictions on marketing of pharmaceutical and biological products, other U.S. federal and state healthcare regulatory laws restrict
business practices in the biopharmaceutical industry, which include, but are not limited to, state and federal anti-kickback, false claims, data privacy and
security, and physician payment and drug pricing transparency laws. Similar laws exist in foreign jurisdictions as well.
The federal Anti-Kickback Statute prohibits, among other things, any person or entity from knowingly and willfully offering, paying, soliciting, receiving
or providing any remuneration, directly or indirectly, overtly or covertly, to induce or in return for purchasing, leasing, ordering, or arranging for or
recommending the purchase, lease, or order of any item or service reimbursable, in whole or in part, under Medicare, Medicaid or other federal healthcare
programs. 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 the one hand and prescribers, purchasers, and formulary managers 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. 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 meet the requirements of a statutory or regulatory 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 statute has been violated. Additionally, 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. The majority of states also have anti-kickback laws, which establish similar prohibitions and in
some cases may apply to items or services reimbursed by any third-party payor, including commercial insurers.
The federal false claims laws, including the civil False Claims Act, prohibit any person or entity from, among other things, knowingly presenting, or
causing to be presented, a false, fictitious or fraudulent claim for payment to, or approval by, the federal government, knowingly making, using, or causing
to be made or used a false record or statement material to a false or fraudulent claim to the federal government, or from knowingly making a false statement
to avoid, decrease or conceal an obligation to pay money to the U.S. federal government. A claim includes “any request or demand” for money or property
presented to the U.S. government. In addition, a claim including items or services resulting from a violation of the federal Anti-Kickback Statute
constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. Actions under the civil False Claims Act may be brought by the
Attorney General or as a qui tam action by a private individual in the name of the government. Violations of the civil False Claims Act can result in very
significant monetary penalties and treble damages. Several pharmaceutical and other healthcare companies have been prosecuted under these laws for,
among other things, allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product.
Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of products for unapproved (e.g., off-
label) uses. In addition, the civil monetary penalties statute imposes penalties against any person who is determined to have presented or caused to be
presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or
fraudulent. Many states also have similar fraud and abuse statutes or regulations that apply to items and services reimbursed under Medicaid and other state
programs, or, in several states, apply regardless of the payor. Given the significant size of actual and potential settlements, it is expected that the
government authorities will continue to devote substantial resources to investigating healthcare providers’ and manufacturers’ compliance with applicable
fraud and abuse laws.
The federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) created additional 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. Similar to the U.S. federal 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.
In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians and certain other healthcare providers.
The ACA imposed, among other things, new annual reporting requirements through the Physician Payments Sunshine Act for covered manufacturers for
certain payments and “transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain
non-physician practitioners including physician assistants and nurse practitioners, and teaching hospitals, as well as ownership and investment interests
held by physicians, as defined by statute, and their immediate family members. Failure to submit timely, accurately and completely the required
information for all payments, transfers of value and ownership or investment interests may result in civil monetary penalties. Covered manufacturers must
submit reports by the 90th day of each subsequent calendar year. In addition, certain states require implementation of compliance programs and compliance
with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, impose
restrictions on marketing practices, and/or tracking and reporting of pricing and marketing information as well as gifts, compensation and other
remuneration or items of value provided to physicians and other healthcare professionals and entities.
38
Violations of any of these laws or any other governmental regulations that may apply may result in significant penalties, including, without limitation,
administrative, civil and criminal penalties, damages, fines, disgorgement, 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, reporting obligations and oversight
if we become subject to a corporate integrity agreement or other agreement is required, and/or individual imprisonment.
To the extent that any of our antibody candidates, once approved, are sold in a foreign country, we may be subject to similar foreign laws and regulations,
which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse laws, and implementation of
corporate compliance programs and reporting of payments or other transfers of value to healthcare professionals.
Privacy and Data Protection Laws in the United States
We may also be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. HIPAA, as
amended by the Health Information Technology for Economic and Clinical Health Act (HITECH) and their respective implementing regulations, impose
specified requirements relating to the privacy, security and transmission of individually identifiable health information held by covered entities and their
business associates. Among other things, HITECH made HIPAA’s security standards directly applicable to “business associates,” defined as independent
contractors or agents of covered entities that create, receive, maintain or transmit 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, business associates and
possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal
HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy and security of
health information in certain circumstances, many of which differ from each other in significant ways and may not have the same requirements, thus
complicating compliance efforts. By way of example, California enacted the California Consumer Privacy Act (CCPA) effective January 1, 2020, which
gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing, and receive
detailed information about how their personal information is used. The CCPA provides for civil penalties for violations, as well as a private right of action
for data breaches that has increased the likelihood of, and risks associated with, data breach litigation. Additionally, the California Privacy Rights Act
(CPRA) generally went into effect on January 1, 2023 and significantly amends the CCPA. It imposes additional data protection obligations on covered
companies doing business in California, including additional consumer rights processes and opt outs for certain uses of sensitive data. It also creates a new
California data protection agency specifically tasked to enforce the law, which will likely result in increased regulatory scrutiny of California businesses in
the areas of data protection and security. Similar laws have passed in Virginia, Connecticut, Utah and Colorado, and have been proposed in other states and
at the federal level, reflecting a trend toward more stringent privacy legislation in the United States. The enactment of such laws could have potentially
conflicting requirements that would make compliance challenging.
Privacy and Data Protection Laws in Europe
We are subject to European laws relating to our and our suppliers’, collaborators’ and subcontractors’ (where they act as processors) collection, control,
processing and other use of personal data (i.e., any data relating to an identifiable living individual, whether that individual can be identified directly or
indirectly). We are subject to the supervision of local data protection authorities in those jurisdictions where we are established, and where we process
personal data in the context of the activities of that establishment (e.g., undertaking clinical trials). We and our suppliers, collaborators and subcontractors
process personal data including in relation to our employees, employees of customers, clinical trial patients, healthcare professionals and employees of
suppliers including health and medical information. The data privacy regime in the EU includes the General Data Protection Regulation (GDPR) and
national laws and regulations implementing or supplementing it.
The GDPR requires that personal data is only collected for specified, explicit and legal purposes as set out in the GDPR or local laws, and the data may
then only be processed in a manner compatible with those purposes. The personal data collected and processed must be adequate, relevant and not
excessive in relation to the purposes for which it is collected and processed, it must be held securely, not transferred outside of the European Economic
Area (EEA) unless certain steps are taken to ensure an adequate level of protection, and must not be retained for longer than necessary for the purposes for
which it was collected. In addition, the GDPR requires companies processing personal data to take certain organizational steps to ensure that they have
adequate records, policies, security, training and governance frameworks in place to ensure, and to be able to demonstrate, protection. For example, the
GDPR requires us to make more detailed disclosures to data subjects, requires disclosure of the legal basis on which we can process personal data, makes it
harder for us to obtain valid consent for processing, may require the appointment of a data protection officer where sensitive personal data (i.e., health data)
is processed on a sufficiently large scale, introduces mandatory data breach notification throughout the EU and imposes additional obligations on us when
we are contracting with certain service providers.
39
In addition, to the extent a company processes, controls or otherwise uses “special category” personal data (including patients’ health or medical
information, genetic information and biometric information), more stringent rules apply, further limiting the circumstances and the manner in which a
company is legally permitted to process that data. The GDPR provides a broad right for EU and EEA member states to create supplemental national laws
which may result in divergence across Europe making it harder to maintain a consistent operating model or standard operating procedures. Such laws, for
example, may relate to the processing of health, genetic and biometric data, which could further limit our ability to use and share such data or could cause
our costs to increase, and harm our business and financial condition.
There are costs and administrative burdens associated with compliance with the GDPR and the resultant changes in the EU and EEA member states’
national laws. Any failure or perceived failure to comply with global privacy laws carries with it the risk of significant penalties and sanctions of up to €20
million or up to 4% of total worldwide annual turnover of the preceding financial year. Additionally, following the United Kingdom’s withdrawal from the
EEA and the EU, and the expiry of the transition period, companies have to comply with the GDPR and the GDPR as incorporated into United Kingdom
national law, the latter regime having the ability to separately fine up to the greater of €20 million (£17.5 million) or 4% of global turnover. These laws or
new interpretations, enactments or supplementary forms of these laws, could create liability for us, could impose additional operational requirements on our
business, could affect the manner in which we use and transmit patient information and could increase our cost of doing business. Claims of violations of
privacy rights or contractual breaches, even if we are not found liable, could be expensive and time-consuming to defend and could result in adverse
publicity that could harm our business.
Among other requirements, the GDPR regulates transfers of personal data subject to the GDPR to third countries that have not been found to provide
adequate protection to such personal data, including the United States, and the efficacy and longevity of current transfer mechanisms between the EEA, and
the United States remains uncertain. Case law from the Court of Justice of the European Union (CJEU) states that reliance on the standard contractual
clauses - a standard form of contract approved by the European Commission as an adequate personal data transfer mechanism - alone may not necessarily
be sufficient in all circumstances and that transfers must be assessed on a case-by-case basis. On July 10, 2023, the European Commission adopted its
Adequacy Decision in relation to the new EU-US Data Privacy Framework (DPF), rendering the DPF effective as a GDPR transfer mechanism to U.S.
entities self-certified under the DPF.
These recent developments may require us to review and amend the legal mechanisms by which we make and/ or receive personal data transfers to/ in the
U.S. As supervisory authorities issue further guidance on personal data export mechanisms, including circumstances where the standard contractual
clauses 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 between and among countries and regions in which we operate, it could affect the manner in which we
provide our services, the geographical location or segregation of our relevant systems and operations, and could adversely affect our financial results.
From January 1, 2021, we are subject to the GDPR and also the United Kingdom (UK) GDPR, which, together with the amended UK Data Protection Act
2018, retains the GDPR in UK national law. On October 12, 2023, the UK Extension to the DPF came into effect (as approved by the UK Government), as
a data transfer mechanism from the UK to U.S. entities self-certified under the DPF. As we continue to expand into other foreign countries and
jurisdictions, we may be subject to additional laws and regulations that may affect how we conduct business.
Coverage and Reimbursement
Significant uncertainty exists as to the coverage and reimbursement status of any pharmaceutical or biological products for which we obtain regulatory
approval. In the United States and markets in other countries, patients who are prescribed treatments for their conditions and providers performing the
prescribed services generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use our products
unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products. Sales of any products for which we
receive regulatory approval for commercial sale will therefore depend, in part, on the availability of coverage and adequate reimbursement from third-party
payors. Third-party payors include government authorities, managed care plans, private health insurers and other organizations.
In the United States, the process for determining whether a third-party payor will provide coverage for a pharmaceutical or biological product typically is
separate from the process for setting the price of such product or for establishing the reimbursement rate that the payor will pay for the product once
coverage is approved. For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly
difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or
procedure in which the product is used may not be available, which may impact physician utilization. A decision by a third-party payor not to cover our
bispecific antibody candidates could reduce physician utilization of our products once approved and have a material adverse effect on our sales, results of
operations and financial condition. Moreover, a third-party payor’s decision to provide coverage for a pharmaceutical or biological product does not imply
that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable
40
us to maintain price levels sufficient to realize an appropriate return on our investment in product development. Additionally, coverage and reimbursement
for new products can differ significantly from payor to payor. One third-party payor’s decision to cover a particular medical product or service does not
ensure that other payors will also provide coverage for the medical product or service, or will provide coverage at an adequate reimbursement rate. As a
result, the coverage determination process will require us to provide scientific and clinical support for the use of our products to each payor separately and
will be a time-consuming process.
In the EU, governments influence the price of products through their pricing and reimbursement rules and control of national health care systems that fund
a large part of the cost of those products to consumers. Member states are free to restrict the range of pharmaceutical products for which their national
health insurance systems provide reimbursement, and to control the prices and reimbursement levels of pharmaceutical products for human use. Some
jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed to by the
government. Member states may approve a specific price or level of reimbursement for the pharmaceutical product, or alternatively adopt a system of direct
or indirect controls on the profitability of the company responsible for placing the pharmaceutical product on the market, including volume-based
arrangements, caps and reference pricing mechanisms. To obtain reimbursement or pricing approval, some of these countries may require the completion of
clinical trials that compare the cost effectiveness of a particular product candidate to currently available therapies. Other member states allow companies to
fix their own prices for medicines, but monitor and control company profits. The downward pressure on health care costs in general, particularly
prescription products, has become very 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 a commercial pressure on pricing within a country.
The containment of healthcare costs has become a priority of federal, state and foreign governments, and the prices of pharmaceutical or biological
products have been a focus in this effort. Third-party payors are increasingly challenging the prices charged for medical products and services, examining
the medical necessity and reviewing the cost-effectiveness of pharmaceutical or biological products, medical devices and medical services, in addition to
questioning safety and efficacy. If these third-party payors do not consider our products to be cost-effective compared to other available therapies, they may
not cover our products after FDA approval or, if they do, the level of payment may not be sufficient to allow us to sell our products at a profit.
Healthcare Reform
A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and other third-party payors have attempted to
control costs by limiting coverage and the amount of reimbursement for particular medical products. For example, in March 2010, the ACA was enacted,
which, among other things, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program; introduced 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; extended the Medicaid Drug Rebate Program to utilization of prescriptions of individuals enrolled in Medicaid managed
care plans; imposed mandatory discounts for certain Medicare Part D beneficiaries as a condition for manufacturers’ outpatient drugs coverage under
Medicare Part D; subjected drug manufacturers to new annual fees based on pharmaceutical companies’ share of sales to federal healthcare programs; and
created a new Patient Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research,
along with funding for such research.
Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme
Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA.
In addition, the American Rescue Plan Act of 2021 as signed into law, which eliminated the statutory Medicaid drug rebate cap, beginning January 1, 2024.
The rebate was previously capped at 100% of a drug’s AMP. Moreover, recently there has been heightened governmental scrutiny over the manner in which
manufacturers set prices for their marketed products, which have resulted in several recent Congressional inquiries and proposed and enacted 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 pharmaceutical and biological products. Most recently, on August 16, 2022 the Inflation
Reduction Act of 2022 (“IRA”) was signed into law. Among other things, the IRA requires manufacturers of certain drugs to engage in price negotiations
with Medicare (beginning in 2026), with prices that can be negotiated subject to a cap; imposes rebates under Medicare Part B and Medicare Part D to
penalize price increases that outpace inflation (first due in 2023); and replaces the Part D coverage gap discount program with a new discounting program
(beginning in 2025). The IRA permits the Secretary of the Department of Health and Human Services (HHS) to implement many of these provisions
through guidance, as opposed to regulation, for the initial years. In August 2023, HHS announced the list of the first ten drugs that will be subject to price
negotiations, although the Medicare drug price negotiation program is currently subject to legal challenges. For that and other reasons, it is currently
unclear how the IRA will be effectuated, and the impact of the IRA on the pharmaceutical industry cannot yet be fully determined. Individual states in the
United States have also become increasingly active in passing legislation and implementing 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
41
importation from other countries and bulk purchasing. The implementation of cost containment measures or other healthcare reforms may prevent us from
being able to generate revenue, attain profitability or commercialize our drugs.
We expect that additional state, federal and foreign healthcare reform measures will be adopted in the future, any of which could limit the amounts that
federal and state governments will pay for healthcare products and services, which could result in reduced demand for our products once approved or
additional pricing pressures. Any reduction in reimbursement from Medicare or other government-funded programs may result in a similar reduction in
payments from private payors.
Employees
As of January 1, 2024, we had 172 full-time employees and 57 part-time employees, including 99 employees with M.D. or Ph.D. degrees. Of these
employees, 168 were primarily engaged in research and development activities and 61 were primarily engaged in general and administrative activities. We
are proud of our diversity, with 105 employees identifying as male and 124 identifying as female and with over 29 different nationalities represented. None
of our employees are part of a labor union, and we consider our employee relations to be good.
Our Values and Culture
Our goal is to help patients overcome the devastating disease of cancer. Our values reflect the way we go about achieving this goal. It is a declaration both
of who we are and who we want to be. These are principles we strive to live up to and to be measured by:
• We are creative problem solvers – we nurture inquisitive minds and diverse talents, to create solutions to some of today’s most pressing medical
needs in oncology. We accept setbacks as an inevitable part of innovation, and we welcome them as an opportunity to learn.
• We commit and move as one – we are one company with a common goal of closing in on cancer. We work as a team and encourage a diversity of
perspectives. When we take a decision, we unite and move forward together.
• We aim at excellence – our work impacts lives. We honor this with our every decision and take collective responsibility to uphold our goal. We
strive to do the right things and take pride in doing them well.
• We care – everything we do, we do because we care. We care deeply about improving patients’ lives. We respect and support each other and the
communities around us.
We believe our values are an important facet of who we are and how we will deliver on our goals to close in on cancer, and meet our mission.

Code of Business Conduct and Ethics
All employees are expected to conduct business with the highest standard of business ethics. Each employee receives and we ask each employee to agree to
follow the Merus Code of Business Conduct and Ethics. Employees are encouraged to discuss any related concerns, including with management or report
concerns anonymously through an Ethics Hotline. Any report received on the Ethics Hotline is investigated by our General Counsel or the Audit
Committee, as applicable. Further, we have two employee confidential advisors, as well as an external confidential advisor, with whom our employees
may discuss ways of addressing, preventing and combating inappropriate behavior in the workplace. No one shall be subject to adverse action who in good
faith reports an incident of violation of our policies, provides information, or otherwise assists in any investigation. Any employee who retaliates against
another in violation of our policies will be subjected to disciplinary action, up to and including termination.
As part of its regular review of the corporate governance policies of Merus N.V., our board of directors, with consent of the Company’s Works Council
adopted and approved the updated and amended Company Code of Business Conduct and Ethics (the "Business Code") effective January 15, 2024. The
Business Code supersedes the previous version and reflects, among other things, certain updates which we believe are consistent with current governance
best practices.
The amendments include revisions to Annex I of the Business Code to align with the Dutch Whistleblower Protection Act (wet bescherming
klokkenluiders) (“WPA”), including (i) an updated internal reporting procedure; (ii) the manner in which suspected wrongdoing outside the organization
can be reported to competent authorities and, where applicable, to institutions, bodies, offices and agencies of the European Union; and (iii) enhancements
and clarifications related to the protection and confidentiality afforded to those reporting a suspicion of wrongdoing under the Business Code.
Employership, Leadership and Training
We perform periodic surveys, which give employees the opportunity to provide feedback on our employee engagement, commitment, leadership, work
atmosphere, role clarity, psychological security, and employership, as well as annual surveys of a smaller scope. These surveys are managed by a third-
party vendor to encourage openness and honesty in responding to questions regarding these important factors. In 2021, our employee response rate to our
biannual survey was 87 percent, which we believe is an indication that our employees recognize that their feedback is important. Further, we were named a
“World-Class Workplace” by the third-party vendor based on the outcome of the employee engagement survey, which demonstrated that Merus scored
above other companies in the Netherlands on aspects of employership themes and how likely is it that an employee would recommend Merus as an
employer to others. Further, we scored higher marks on pride of organization, inspiring vision of the future, leadership, work atmosphere and satisfaction
about the organization than benchmarks for employership established by the vendor through its survey results based on average scores across surveys from
over 500 other organizations.
Critical to our success is the hiring, training, retention and promotion of our employees, as we develop the competencies needed for the advancement of our
company today and that will be needed in the coming years. Accordingly, we developed a variety of leadership and development opportunities under an
umbrella program we refer to as the Merus Academy. A pillar of this program is a leadership development program, where we work with a third-party
provider to help train and enhance the leadership skills of
43
employees at the director to vice president level. Another pillar is a leadership essentials training, which we offer to our scientists to help enhance their
individual effectiveness, improve leadership ability, develop skills to address change and conflict management, and enhance their thought leadership within
the organization. A third pillar is our implementation of an online learning platform, which offers our employees training courses across a variety of
disciplines. Each of these pillars supports our talent management and advancement to drive our corporate goals.
Equal Opportunity
We are an equal employment opportunity employer that does not discriminate on the basis of actual or perceived race, color, religious creed, national
origin, sex (including pregnancy, childbirth, and related medical conditions), sexual orientation, age, ancestry, disability or perceived disability, qualified
handicap, gender identity, military status, veteran status, certain criminal records, genetic information or testing, HIV testing, or any other characteristic
protected by applicable federal, state or local laws (each, a “Protected Characteristic”). We are dedicated to this policy with respect to recruitment, hiring,
placement, promotion, transfer, training, compensation, benefits, employee activities and general treatment during employment. Equal opportunities are
important to us. To evaluate our performance, we asked an external party to assess whether there is a difference in compensation of men and women at
Merus. The outcome of the assessment was that there was not different compensation between men and women in comparable positions/roles within
Merus. Equal opportunity is also reflected in the diversity within our Management Team, which is a mixture of men and women, and in our Board
Diversity and Inclusion Policy.
Compensation Philosophy, Incentives and Retention
Our human capital strategies, hiring and retention outcomes are reviewed on a regular basis with our board of directors, to align with our overall business
strategies. Further, we review our compensation philosophy annually with the compensation committee of our board of directors, as well as on an ad hoc
basis to receive input on new hires during the course of the year. Our compensation committee, relying on their extensive experience in the
biopharmaceutical industry and receiving input from our external compensation advisors, review our short and long term incentive programs, and evaluate
our group of peer companies to help achieve our hiring and retention goals during the course of the year. Our board of directors receives regular updates on
these objectives, including headcount plans, achievement against goals and attrition rates during the year.
Health and Safety
The health and safety of our employees is a top priority. We have implemented workforce policies for our headquarters in the Netherlands, as well as our
subsidiary in Cambridge, Massachusetts, for taking measures to comply with changing rules, regulations and recommendations by the U.S. Center for
Disease Control and Prevention (CDC) and European local health agencies, including the Dutch National Institute for Health and Environment or Het
Rijksinstituut voor Volksgezondheid en Milieu (RIVM), and local regulations as may apply to the health and safety of our employees. We support a
distributed workforce and may, depending on conditions and health authority guidance, recommend our employees in the Netherlands and employees of
our subsidiary, Merus US, Inc., in the U.S. work remotely. For those employees working at our offices and laboratory in Utrecht, they are required to
follow requirements consistent with the guidance provided by the RIVM for the Netherlands, and employees of our subsidiary Merus US, Inc. are required
to abide by the guidelines of the CDC, and Federal, state and local regulations for the U.S.
Employee Health and Wellbeing Support
Healthy and happy employees are important to us and therefore we have launched several initiatives to be able to support our employees with health and
wellbeing. One of these initiatives is the option for employees that are experiencing financial difficulties on a personal level due to the current challenging
economic circumstances, to get support from an external provider to get better insight in their financial situation and help them to set up a plan and/or take
next steps to deal with these financial difficulties.
In addition, we offer our employees a medical check and/or a so-called fit-test to check-in and get advice on their overall health. We also offer our
employees the option of a consult with an ergonomist to ensure their in-office workplace is correctly set up to limit the possibility of workplace related
health issues from occurring.
Sustainability and Community Relations
At Merus, we want to play a positive role in society, not only by developing potentially meaningful medicines, but also by aiming to be responsible for the
impact of our operations on the environment. To contribute to that goal, we have a sustainability team, operating on a volunteer basis and comprised of
members from different business functions throughout the organization. Its mission is to reduce Merus' environmental impact and increase employee
awareness about sustainability through a variety of initiatives in our offices and laboratories.
44
We work with the on-premises catering company to continue to deliver vegan and vegetarian-only options daily. Our catering supplier aims to become
climate neutral by the end of 2024. To reach this goal, it plans to switch to more plant-based proteins, aims at reducing food waste, and looks for circular
solutions for their waste streams, by reducing the use of plastic, choosing recyclable or compostable variants. Fruit and vegetables provided by our caterer
are also locally sourced, reducing energy consumption expended in their transport.
We also have selected our coffee vendor for its sustainability practices, which reports using techniques such as recirculation of heat in the coffee roasting
process, to save up to 75% of energy expenditure, and uses 100% traceable Dutch wind energy. The roastery reports having a climate-resistant garden with
rainwater infiltration. For carbon emissions that cannot be (yet) avoided, the supplier notes that it compensates through fairtrade carbon credits in the coffee
chain. The supplier also aims to reduce waste: coffee beans are delivered in bulk in aluminum-free bags, and coffee machines are refurbished at the end of
their lifecycle.
We have also implemented a sustainable mobility plan referred to as the Merus Employee Cycling Plan, which supports employees to purchase a new or
second hand (e-)bike to commute to Merus, thereby reducing our carbon footprint, lowering city traffic, congestion, and improving the vitality of our
employees. In 2023, 29 employees took part in the Merus Employee Cycling Plan, and 40 employees have been using an NS business card as part of our
offerings to further reduce car usage. This card enables our employees to come to work through public transportation in the Netherlands, helping to reduce
emissions and the impact of congestion in the Netherlands and the Utrecht Science Park.
In 2023, we also donated 150 trees to Trees for All, on behalf of our employees, contributing to reforestation projects in the Netherlands. This program
supports local, sustainable agriculture projects and helps increase the income of farmers, while protecting and preserving nearby forest areas. Merus has
contributed to this program since 2019, resulting in planting approximately 600 trees during this time.
In an effort to reduce electronic waste (e-waste), since 2022, we have introduced a new fleet of laptops with an extended lifecycle of four years, to replace
our previous three-year lifecycle equipment. In 2023, we also donated 161 laptops, five printers and a number of monitors, cables, docking stations,
keyboards and mouses to Close the Gap – an international social enterprise whose goal is to collect high-quality IT devices and offer them to educational,
medical and social projects in developing and emerging countries. For its laptop bags, we have opted for a supplier which produces sustainable bags made
from recycled PET bottles. In 2023, we also opted for 100% recycled paper for all in-office printing.
In our laboratories in Utrecht, recycling efforts are encouraged as much as possible, in alignment with laboratory procedures. To improve plastic waste
management, plastic bottles are reused as waste bins. These plastic bottles are stored for reuse in dedicated spaces throughout the laboratories. In 2023, we
switched to a more sustainable waste bin made from recycled polypropylene for the biological waste in our laboratories. In our offices in Utrecht, waste
bins have been installed to allow waste separation (paper, plastic, and general waste) and to facilitate recycling efforts.
The "Accelerator": a New Sustainable Merus Utrecht Headquarters
Since December 2022, we have been located at our headquarters called the "Accelerator" in the Utrecht Science Park, at 17 Uppsalalaan, 3rd and 4th floor,
3583 CT, Utrecht. This building meets the requirements of the so-called ‘BREEAM Excellent’ certification. BREEAM (Building Research Establishment’s
Environmental Assessment Method) is a method to measure and assess the sustainability of real estate and is used in over 80 countries worldwide. The
method was originally developed by the Building Research Establishment (BRE) and the Dutch Green Building Council (DGBC) has adopted the method
to make it align with the situation in The Netherlands, creating BREEAM-NL. There are specific BREEAM schemes for new buildings, existing (in-use)
building and demolition to tailor the measurements and assessment to the relevant situation. BREEAM certifications are issued by the DGBC. BREEAM
covers a variety of topics and processes, such as the management of the development/built process, a healthy internal building climate, energy efficiency,
transport to, from and in the building, water usage and waste. The BREEAM certification achieved by the Accelerator is the second highest certification
that can be obtained and represents high sustainability performance of the building and the use of best practices in the market to build a building that meets
this certification level. Only about 10% of all office buildings in the Netherlands are certified as ‘BREEAM Excellent.’
To receive the BREEAM Excellence certification a building needs to have a minimum score of 70%. Based on the bespoke scheme used for the assessment
of the Accelerator, the Accelerator scored 72.81% granting it a BREEAM Excellent certification. Certain notable sustainable features of the Accelerator
include: (i) solar paneled roof to provide electrical power; (ii) heating and cooling provided by heat pump to avoid gas usage; (iii) LED lighting, including
presence detection to avoid use of energy when spaces are vacant; and (iv) air handling units with energy recovery.
As part of the BREEAM certification of the Accelerator, the landlord entered into a so-called green lease with each tenant, which provides requirements
that need to be met by the tenants with regard to the design of the tenant’s premises and the use of the building. The green lease includes requirements
concerning among others, heating/cooling, transport and lighting used in and around the building/tenant’s premises.
Environmental, Health and Safety Supplier Standards
45
We adopted the Merus Supplier Standards in September, 2021, to safeguard that our suppliers meet an acceptable standard business conduct and
compliance with laws and regulations. These standards apply to our non-clinical and non-research-related products/services suppliers that provide products
and/or services above a minimum threshold value, and to any sub-contractors of a supplier that are involved in the performance of any agreement between
Merus and such supplier. For higher value contracts, the Supplier Standards form a condition precedent to soliciting bids and proposals from suppliers and
are shared with the supplier for review and confirmation of compliance as part of the bid or proposal.
The Supplier Standards includes a range of standards which vary from compliance with law, any privacy regulations to fair competition and employment.
In short, based on the Supplier Standards, we expect our suppliers (i) to fully comply with applicable laws, rules and regulations; (ii) to not have any
involvement of any kind with or link to bribery or corruption and to abide by all applicable anti-bribery and corruption laws and regulations such as the
Foreign Corrupt Practices Act of 1977, as amended, 15 U.S.C. §§ 78dd-1, et seq. (FCPA) and UK Bribery Act 2010; (iii) to conduct business in a
transparent way, keep their records accurate and not engage in or facilitate any form of money laundering; (iv) to use fair business practices and act in
accordance with applicable antitrust laws; (v) to inform Merus in case of a (potential) conflict of interest; (vi) to respect the right to privacy of individuals,
operate in a manner that is consistent with applicable data protection laws and process personal data provided by Merus with strict confidentiality and only
when having the appropriate technical and organizational structures and procedures in place to ensure the protection of the personal data; (vii) to uphold
human rights, pay fair wages, respect rights of workers and to not use any forced or child labor of any sort; and (viii) to provide a safe and healthy
environment and operate in a socially and environmentally responsible manner. Suppliers of Merus must also (i) comply with any applicable federal, state,
(inter)national and local environmental and health & safety laws and regulations (which include but are not limited to rules on waste, air emissions and
hazardous substances), obtain and maintain the required permits, licenses, authorizations and registrations and follow their operational and reporting
requirements and restrictions; (ii) provide a healthy and safe workplace for its employees and other personnel; and (iii) operate in a socially and
environmentally responsible manner and take measures to proactively protect and minimize the adverse impact of its business on the community,
environment and natural resources, while safeguarding the health and safety of the public. Suppliers are encouraged to conserve natural resources, to avoid
the use of hazardous materials where possible and to engage in activities that reuse and recycle.

Item 1A. Risk Factors.
Investing in our common stock involves a high degree of risk. You should consider carefully the risks described below, together with the other information
included or incorporated by reference in this Annual Report on Form 10-K. If any of the following risks occur, our business, financial condition, results of
operations and future growth prospects could be materially and adversely affected. In these circumstances, the market price of our common stock could
decline. Other events that we do not currently anticipate or that we currently deem immaterial may also affect our business, prospects, financial condition
and results of operations.
RISK FACTORS
Risks Related to Our Business and Industry
We are a clinical-stage company and have incurred significant losses since our inception. We expect to incur losses for the foreseeable future and may
never achieve or maintain profitability.
We are a clinical-stage oncology company with a limited operating history. We have incurred net losses of $154.9 million, $131.2 million and $66.8 million
for the years ended December 31, 2023, 2022, and 2021, respectively. As of December 31, 2023, we had an accumulated deficit of $753.1 million. Our
losses have resulted principally from expenses incurred in research and development of our antibody candidates and from management and administrative
costs and other expenses that we have incurred while building our business infrastructure. We expect to continue to incur significant expenses and
operating losses for the foreseeable future as we continue to advance our antibody candidates from discovery through pre-clinical development and into
clinical trials and seek regulatory approval and pursue commercialization of any approved antibody candidates. We anticipate that we will continue to incur
significant expenses as we:
•
•
•
•
•
•
•
•
•
•
•
•
•
conduct our ongoing, single agent, Phase 1/2 eNRGy clinical trial of zenocutuzumab, our most advanced bispecific antibody candidate,
investigating the treatment of solid tumors that are NRG1+ in monotherapy and, our monitoring and evaluation of the Phase 2 clinical trial
investigating the treatment of CRPC (castration resistant prostate cancer) with zenocutuzumab in combination with an ADT, and monitoring and
evaluation of the NRG1+ NSCLC cohort investigating treatment with zenocutuzumab in combination with afatinib;
conduct our ongoing Phase 1/2 clinical trial of MCLA-158 or petosemtamab for the treatment of solid tumors;
conduct our ongoing Phase 1/2 clinical trial for MCLA-129 for the treatment of solid tumors, which is subject to a collaboration with Betta,
whereby Betta has exclusive rights to develop MCLA-129 in China, and Merus retains all rights ex-China;
conduct our ongoing Phase 1 clinical trial for MCLA-145 for the treatment of advanced solid tumors;
continue the research and development of our other pre-clinical antibody candidates;
expand our clinical programs to explore new potential combination therapies or indications;
expand and enhance our technology platforms, including our Biclonics® technology platform which generates our pipeline of bispecific product
candidates, our Triclonics® technology platform, which generates pre-clinical trispecific candidates and generate and develop additional
multispecific antibody candidates;
seek regulatory approvals for any antibody candidates that successfully complete clinical trials;
potentially establish a sales, marketing and distribution infrastructure and scale-up manufacturing capabilities to commercialize any products for
which we may obtain regulatory approvals;
maintain, expand and protect our intellectual property portfolio;
secure, maintain and/or obtain freedom to operate for our technologies and products;
add clinical, scientific, operational, financial, information technology and management information systems and personnel, including personnel
to support our product development and potential future commercialization efforts and to support our operation as a public company; and
experience any delays or encounter any issues with any of the above, including but not limited to failed studies, complex results, manufacturing,
potential commercialization challenges, safety issues or other regulatory challenges.
We have financed our operations primarily through public offerings and private placements of our common shares and our collaboration and license
agreement with Incyte and Eli Lilly. We have devoted a significant portion of our financial resources and
47
efforts to developing our full-length bispecific antibody therapeutics, which we refer to as Biclonics®, our technology platforms, identifying potential
antibody candidates, conducting pre-clinical studies of a variety of candidates, and conducting our clinical trials of zenocutuzumab, petosemtamab, MCLA-
129 and MCLA-145. We have not completed development of any Biclonics® or any other drugs or biologics.
To become and remain profitable, we must succeed in developing and eventually commercializing products that generate significant revenue. This will
require us to be successful in a range of challenging activities, including completing pre-clinical testing and clinical trials of our antibody candidates,
discovering and developing additional antibody candidates, obtaining regulatory approval for any antibody candidates that successfully complete clinical
trials, establishing manufacturing and marketing capabilities and ultimately selling any products for which we may obtain regulatory approval. We are only
in the preliminary stages of many of these activities. We may never succeed in these activities and, even if we do, may never generate revenue that is
significant enough to achieve profitability.
Because of the numerous risks and uncertainties associated with pharmaceutical product and biological development, we are unable to accurately predict
the timing or amount of increased expenses or when, or if, we will be able to achieve profitability. If we are required by the U.S. Food and Drug
Administration (FDA), or the European Medicines Agency (EMA), or other regulatory authorities to perform studies in addition to those we currently
anticipate, or if there are any delays in completing our clinical trials or the development of any of our antibody candidates, our expenses could increase and
commercial revenue could be further delayed.
Even if we do generate product royalties or product sales, we may never achieve or sustain profitability on a quarterly or annual basis. Our failure to sustain
profitability could depress the market price of our common shares and could impair our ability to raise capital, expand our business, diversify our product
offerings or continue our operations.
We will need additional funding in order to complete development of our antibody candidates and commercialize our products, if approved. If we are
unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.
We expect to continue to incur significant expenses in connection with our ongoing activities, particularly as we conduct our ongoing clinical trials of
zenocutuzumab, petosemtamab, MCLA-129, MCLA-145 and continue to research, develop and conduct pre-clinical studies of our other antibody
candidates. In addition, if we obtain regulatory approval for any of our antibody candidates, we expect to incur significant commercialization expenses
related to product manufacturing, marketing, sales and distribution. Furthermore, we continue to incur 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 could be forced to delay, reduce or eliminate our research and development programs or any future
commercialization efforts. For example, the trading prices for our and other biopharmaceutical companies’ stock have been highly volatile as a result of
disruptions and extreme volatility in the global economy, including rising inflation and interest rates, declines in economic growth, the ongoing conflicts in
Europe and the Middle East and the ongoing impacts of the COVID-19 pandemic. As a result, we may face difficulties raising capital through sales of our
common stock and any such sales may be on unfavorable terms.
Based on our current operating plan, we expect that our existing cash, cash equivalents and investments as of December 31, 2023 will be sufficient to fund
our operations into 2027. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we
currently expect. We maintain the majority of our cash and cash equivalents in accounts with major U.S. and multi-national financial institutions, and our
deposits at these institutions exceed insured limits. Market conditions can impact the viability of these institutions. In the event of failure of any of the
financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we would be able to access uninsured funds in a
timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect our business and financial position. Our future
capital requirements will depend on many factors, including:
•
•
•
•
•
the cost, progress and results of our ongoing clinical trials of zenocutuzumab and petosemtamab, MCLA-129 and MCLA-145;
the success of our collaborations with Incyte and with Lilly to develop antibody candidates;
the cost of manufacturing clinical supplies of our bispecific antibody candidates;
the scope, progress, results and costs of pre-clinical development, laboratory testing and clinical trials for our other antibody candidates;
the costs, timing and outcome of regulatory review of any of our antibody candidates;
48
•
•
•
•
•
•
•
the costs and timing of potential future commercialization activities, including manufacturing, marketing, sales and distribution, for any of
our antibody candidates to the extent any receive marketing approval;
the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and
defending any intellectual property-related claims, including any potential future claims by third parties that we are alleged to be infringing
upon their intellectual property rights;
the costs and timing of securing, maintaining and/or obtaining freedom to operate for our technologies and products;
the revenue, if any, received from commercial sales of our antibody candidates to the extent any receive marketing approval;
the extent to which we can realize planned cost efficiencies;
the effect of competing technological and market developments; and
the extent to which we acquire or invest in businesses, products and technologies, including our existing collaborations and any other future
licensing or collaboration arrangements for any of our antibody candidates.
49
We depend heavily on the success of our antibody candidates, and we cannot give any assurance that any of our antibody candidates will receive
regulatory approval, which is necessary before they can be commercialized. If we, any of our collaborators, or any other strategic partners we may
enter into collaboration agreements with for the development and commercialization of our antibody candidates, are unable to commercialize our
antibody candidates, or experience significant delays in doing so, our business, financial condition and results of operations will be materially
adversely affected.
We have invested a significant portion of our efforts and financial resources in the development of bispecific antibody candidates using our Biclonics®
technology platform and in development of multi-specific antibody candidates using our Triclonics® technology platform. Our ability to generate royalty
and product revenues, which we do not expect will occur for at least the next year, if ever, will depend heavily on the successful development and eventual
commercialization of these antibody candidates, which may never occur. We currently generate no revenues from sales of any products, and we may never
be able to develop or commercialize a marketable product. Each of our bispecific antibody candidates and pre-clinical antibody candidates will require
additional clinical development, management of clinical, pre-clinical and manufacturing activities, regulatory approval in multiple jurisdictions, obtaining
manufacturing supply, including commercial manufacturing supply, building of a commercial organization, substantial investment and significant
marketing efforts before we generate any revenues from product sales. We are not permitted to market or promote any of our antibody candidates before we
receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any of our
antibody candidates. The success of our antibody candidates will depend on several factors, including the following:
•
•
•
for antibody candidates which we may license to others, such as to our collaborators, the successful efforts of those parties in completing
clinical trials of, receipt of regulatory approval for and commercialization of such antibody candidates;
for the antibody candidates to which we retain rights, completion of pre-clinical studies and clinical trials of, receipt of marketing approvals
for, establishment of commercial manufacturing supplies of and successful commercialization of such antibody candidates; and
for all of our antibody candidates, if approved, acceptance of our antibody candidates by patients, the medical community and third-party
payors, effectively competing with other therapies, a continued acceptable safety profile following approval and qualifying for, maintaining,
enforcing and defending our intellectual property rights and claims.
If we or our collaborators, as applicable, do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or
an inability to successfully commercialize our antibody candidates, which would materially adversely affect our business, financial condition and results of
operations.
We have not previously submitted a Biologics License Application (BLA), to the FDA, a marketing authorization application (MAA) to the EMA, or
similar regulatory approval filings to comparable foreign authorities, for any antibody candidate, and we cannot be certain that any of our antibody
candidates will be successful in clinical trials or receive regulatory approval. Further, our antibody candidates may not receive regulatory approval even if
they are successful in clinical trials. If we do not receive regulatory approvals for our antibody candidates, we may not be able to continue our operations.
Even if we successfully obtain regulatory approvals to market one or more of our antibody candidates, our revenues will be dependent, in part, upon the
size of the markets in the territories for which we gain regulatory approval and have commercial rights. If the markets for patient subsets that we are
targeting are not as significant as we estimate, we may not generate significant revenues from sales of such products, if approved.
We plan to seek regulatory approval to commercialize our antibody candidates both in the United States and the European Union (EU), and potentially in
additional foreign countries. While the scope of regulatory approval is similar in other countries, to obtain separate regulatory approval in many other
countries we must comply with the numerous and varying regulatory requirements of such countries regarding safety and efficacy and governing, among
other things, clinical trials and commercial sales, pricing and distribution of our antibody candidates, and we cannot predict success in these jurisdictions.
50
The Biclonics® technology platform and Triclonics® technology platform are unproven, novel approaches to the production of biologics for
therapeutic intervention.
We have not received regulatory approval for a therapeutic based on a full-length human bispecific or trispecific IgG approach. We cannot be certain that
our approach will lead to the development of approvable or marketable products. In addition, our Biclonics® and Triclonics® may have different
effectiveness rates in various indications and in different geographical areas. Finally, the FDA, the EMA or other regulatory agencies may lack experience
in evaluating the safety and efficacy of products based on Biclonics® and Triclonics® therapeutics, which could result in a longer than expected regulatory
review process, increase our expected development costs and delay or prevent commercialization of our antibody candidates.
Our Biclonics® and Triclonics® technology platforms rely on third parties for biological materials. Some biological materials have not always met our
expectations or requirements, and any disruption in the supply of these biological materials could materially adversely affect our business. Although we
have control processes, auditing and screening procedures, biological materials are susceptible to damage and contamination and may contain active
pathogens. Improper filling or storage of these materials, by us or any third-party suppliers, may require us to destroy some of our biological raw materials
or antibody candidates.
Failure to successfully validate, develop and obtain regulatory approval or certification for companion diagnostics could harm our development
strategy.
We may seek to identify patient subsets within a disease category that may derive selective and meaningful benefit from the antibody candidates we are
developing. Through collaborations or license agreements, companion diagnostics may help us to more accurately identify patients within a particular
subset, both during our clinical trials and in connection with the commercialization of our antibody candidates, if approved. Companion diagnostics are
subject to regulation by the FDA, and comparable foreign regulatory authorities as medical devices and typically require separate regulatory approval (or
clearance, or certification) prior to commercialization. The development of companion diagnostics in collaboration with or via license agreements with
third parties, may make us potentially dependent on the scientific insights and sustained cooperation and effort of any third-party collaborators in
developing and obtaining approval (or clearance, or certification) for companion diagnostics. Difficulties in developing and obtaining approval or
certification for any companion diagnostics may be encountered, including as it concerns issues relating to selectivity/specificity, analytical validation,
reproducibility or clinical validation. Any delay or failure to develop or obtain regulatory approval (or clearance, or certification) of companion diagnostics
could delay or prevent approval of our antibody candidates. In addition, production difficulties may be encountered that could constrain the supply of the
companion diagnostics, and difficulties may arise in gaining acceptance of the use of the companion diagnostics in the clinical community. If such
companion diagnostics fail to gain market acceptance, it could have an adverse effect on our ability to derive revenues from sales of our products. 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 antibody 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 companion diagnostic test
for use in connection with the development and commercialization of our antibody candidates or do so on commercially reasonable terms, which could
adversely affect and/or delay the development or commercialization of our antibody candidates.
Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.
Since our inception in 2003, we have devoted a significant portion of our resources to developing zenocutuzumab, petosemtamab, MCLA-129, MCLA-145
and our other antibody candidates, building our intellectual property portfolio, developing our clinical manufacturing supply chain, generating and
enhancing our Biclonics® and Triclonics® technology platforms, planning our business, raising capital and providing general and administrative support
for these operations. While we have ongoing clinical trials for zenocutuzumab, petosemtamab, MCLA-129 and MCLA-145, we have not successfully
completed any clinical trials for any antibody candidate. We have not yet demonstrated our ability to successfully complete any Phase 3 or registrational
trials or address other registrational risks related to our clinical trials, to obtain regulatory approvals, to manufacture a commercial scale product or arrange
for a third party to do so on our behalf or to conduct sales and marketing activities necessary for successful product commercialization. Additionally, 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. Consequently, any predictions you make about our future success or viability may not be as accurate as they could
be if we had a longer operating history.
51
Raising additional capital may cause dilution to our holders, restrict our operations or require us to relinquish rights to our technologies or antibody
candidates.
Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through equity or debt financings and upfront
and milestone payments, if any, received under our existing collaborations and any other future licenses or collaborations, together with our existing cash
and cash equivalents. In order to accomplish our business objectives and further develop our product pipeline, we will, however, need to seek additional
funds. If we raise additional capital through the sale of equity or convertible debt securities, our existing shareholders’ ownership interests will be diluted,
and the terms of these securities may include liquidation or other preferences that adversely affect our existing shareholders’ rights as holders of our
common shares. In addition, the possibility of such issuance may cause the market price of our common shares to decline. Debt financing, if available, may
result in increased fixed payment obligations and involve agreements that include covenants limiting or restricting our ability to take specific actions, such
as incurring additional debt, making capital expenditures, declaring dividends, or acquiring, selling or licensing intellectual property rights, which could
adversely impact our ability to conduct our business.
If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have
to relinquish valuable rights to our intellectual property, technologies, future revenue streams or antibody candidates or grant licenses on terms that may not
be favorable to us. We could also be required to seek funds through arrangements with collaborators or others at an earlier stage than otherwise would be
desirable. Any of these occurrences may have a material adverse effect on our business, operating results and prospects.
Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and
commercialize our antibody candidates. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms
acceptable to us, if at all. For example, the trading prices for our and other biopharmaceutical companies’ stock have been highly volatile as a result of
disruptions and extreme volatility in the global economy, including rising inflation and interest rates, declines in economic growth, global instability,
including the ongoing conflict in Europe and the Middle East and continuing impact, if any, of the COVID-19 pandemic. As a result, we may face
difficulties raising capital through sales of our common stock and any such sales may be on unfavorable terms. If we are unable to obtain funding on a
timely basis, we may be required to significantly curtail, delay or discontinue one or more of our research or development programs or the
commercialization of any of our antibody candidates, if approved, or be unable to expand our operations or otherwise capitalize on our business
opportunities, as desired, which could materially affect our business, financial condition and results of operations.
Our business may become subject to economic, political, regulatory and other risks associated with international operations.
As a company based in the Netherlands, our business is subject to risks associated with conducting business internationally. Many of our suppliers and
collaborative 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, in non-U.S. economies and markets;
differing regulatory requirements for drug approvals in non-U.S. countries;
differing jurisdictions could present different issues for securing, maintaining and/or obtaining freedom to operate in such jurisdictions;
potentially reduced protection for intellectual property rights;
difficulties in compliance with non-U.S. laws and regulations;
changes in non-U.S. regulations and customs, tariffs and trade barriers;
changes in non-U.S. currency exchange rates of the euro and currency controls;
changes in a specific country’s or region’s political or economic environment;
trade protection measures, import or export licensing requirements or other restrictive actions by U.S. or non-U.S. governments;
differing reimbursement regimes and price controls in certain non-U.S. markets;
negative consequences from changes in tax laws;
52
•
•
•
•
•
•
•
compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;
compliance with international privacy regulations, including the European Union General Data Protection Regulation (GDPR) and United
Kingdom General Data Protection Regulation (UK GDPR);
negative consequences from the United Kingdom’s withdrawal from the EU, and its potential impact on supply-chain and our personnel;
workforce uncertainty in countries where labor unrest is more common than in the United States;
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, riots and terrorism, as well as the ongoing conflict in Europe and
Middle East, or natural disasters including earthquakes, typhoons, floods, fires, epidemics or public health emergencies and U.S. or non-
U.S. governmental actions or restrictions related thereto.
Exchange rate fluctuations or abandonment of the euro currency may materially affect our results of operations and financial condition.
Due to the international scope of our operations, fluctuations in exchange rates, particularly between the euro and the U.S. dollar, may adversely affect us.
Although we are based in the Netherlands, we source research and development, manufacturing, consulting and other services from several countries.
Further, potential future revenue may be derived from abroad, particularly from the United States. Additionally, our funding has mainly come from
investors and collaborators mainly in the United States. As a result, our business and share price may be affected by fluctuations in foreign exchange rates
between the euro and these other currencies, which may also have a significant impact on our reported results of operations and cash flows from period to
period. Currently, we do not have any exchange rate hedging arrangements in place.
In addition, the possible abandonment of the euro by one or more members of the EU could materially affect our business in the future. Despite measures
taken by the EU to provide funding to certain EU member states in financial difficulties and by a number of European countries to stabilize their economies
and reduce their debt burdens, it is possible that the euro could be abandoned in the future as a currency by countries that have adopted its use. This could
lead to the re-introduction of individual currencies in one or more EU member states, or in more extreme circumstances, the dissolution of the EU. The
effects on our business of a potential dissolution of the EU, the exit of one or more EU member states from the EU or the abandonment of the euro as a
currency, are impossible to predict with certainty, and any such events could have a material adverse effect on our business, financial condition and results
of operations.
Risks from improper conduct by our employees, agents, contractors, or collaborators could adversely affect our reputation, business, prospects,
operating results, and financial condition.
We cannot ensure that our compliance controls, policies, and procedures will in every instance protect us from acts committed by our employees, agents,
contractors, or collaborators that would violate the laws or regulations of the jurisdictions in which we operate, including, without limitation, health care,
employment, foreign corrupt practices, trade restrictions and sanctions, environmental, import and export requirements, competition, patient privacy and
other privacy laws and regulations. Such improper actions could subject us to civil or criminal investigations, and monetary and injunctive penalties, and
could adversely impact our ability to conduct business, operating results, and reputation.
We are subject to a number of anti-corruption laws, including the Foreign Corrupt Practices Act (FCPA) in the United States, the Bribery Act in the United
Kingdom and the anti-corruption provisions of the Dutch Criminal Code in the Netherlands. Our failure to comply with anti-corruption laws applicable to
us could result in penalties, which could harm our reputation and harm our business, financial condition, results of operations, cash flows or prospects. The
FCPA generally prohibits companies and their intermediaries from making improper payments to foreign officials for the purpose of improperly or
corruptly obtaining or keeping business, obtaining preferential treatment and/or other undue benefits or advantages. The FCPA also requires public
companies to maintain accurate books and records and devise a system of sufficient internal accounting controls. We regularly review and update our
policies and procedures and internal controls designed to provide reasonable assurance that we, our employees, distributors and other intermediaries
comply with the anti-corruption laws to which we are subject. However, there are inherent limitations to the effectiveness of any policies, procedures and
internal controls, including the possibility of human error and the circumvention or
53
overriding of the policies, procedures and internal controls. There can be no assurance that such policies or procedures or internal controls will work
effectively at all times or protect us against liability under these or other laws for actions taken by our employees, distributors and other intermediaries with
respect to our business.
The Securities and Exchange Commission (SEC) and Department of Justice continue to view FCPA enforcement activities as a high priority. There is no
certainty that all of our employees, agents, contractors, or collaborators, or those of our affiliates, will comply with all applicable laws and regulations,
particularly given the high level of complexity of these laws. Violations of these laws and regulations could result in fines, criminal sanctions against us,
our officers, or our employees, requirements to obtain export licenses, cessation of business activities in sanctioned countries, implementation of
compliance programs, and prohibitions on the conduct of our business. Any such violations could materially damage our reputation, our brand, our
international operations, our ability to attract and retain employees, and our business, prospects, operating results, and financial condition.
The United Kingdom’s withdrawal from the European Union may have a negative effect on global economic conditions and financial markets, which
could materially affect our financial condition and results of operations.
Since the end of the Brexit transition period on January 1, 2021, Great Britain (England, Scotland and Wales) has not been directly subject to EU laws,
however under the terms of the Ireland/Northern Ireland Protocol, EU laws generally apply to Northern Ireland. However, on February 27, 2023, the UK
Government and the European Commission reached political consensus on the “Windsor Framework,” which will revise the Northern Ireland protocol.
Under the proposed changes, Northern Ireland would be reintegrated under the regulatory authority of the UK regulator with respect to medicinal products.
The implementation of the Windsor Framework will occur in various stages, with new arrangements relating to the supply of medicines into Northern
Ireland due to take effect in 2025. There could be additional uncertainty and risk around what these changes will mean for any of our business operations in
the UK.
The EU laws that have been transposed into United Kingdom (UK) law through secondary legislation remain applicable in Great Britain. In addition, new
legislation such as the EU Clinical Trials Regulation (CTR) is not applicable in Great Britain. The UK government has passed the Medicines and Medical
Devices Act 2021, which introduces delegated powers in favor of the Secretary of State or an ‘appropriate authority’ to amend or supplement existing
regulations in the area of medicinal products and medical devices. This allows new rules to be introduced in the future by way of secondary legislation,
which aims to allow flexibility in addressing regulatory gaps and future changes in the fields of human medicines, clinical trials and medical devices.
The EU-UK Trade and Cooperation Agreement (TCA), came into effect on January 1, 2021. The TCA includes provisions affecting pharmaceutical
businesses (including on customs and tariffs). In addition, there are some specific provisions concerning pharmaceuticals. These include the mutual
recognition of Good Manufacturing Practice (GMP) inspections of manufacturing facilities for medicinal products and GMP documents issued. The TCA
does not, however, contain wholesale mutual recognition of UK and EU pharmaceutical regulations and product standards, and it can be expected that there
may be divergent local requirements in the UK from the EU in the future, which may impact clinical and development activities that occur in the UK in the
future. Similarly, clinical trial submissions and data for activity in the UK will not be able to be bundled with those of EU member states within the EMA
Clinical Trial Information System (CTIS), adding further complexity, cost and potential risk to future clinical and development activity in the UK.
Significant political and economic uncertainty remains about how much the relationship between the UK and EU will differ as a result of the UK’s
withdrawal.
The COVID-19 pandemic has and may continue to adversely impact our business, including our pre-clinical studies and clinical trials, financial
condition and results of operations.
The COVID-19 pandemic presented a substantial public health and economic challenge around the world. The COVID-19 pandemic and related
precautions continue to have certain direct or indirect impacts on our clinical trials, including enrollment, new, planned clinical trial site openings, patient
visits, and on-site monitoring of our clinical trials. As a result of the COVID-19 pandemic, we may experience certain disruptions that could impact our
business, pre-clinical studies and clinical trials. We continue to monitor and assess potential impact of the COVID-19 pandemic.
As a result of COVID-19, we may face difficulties with and delays in performance of certain chemistry, manufacturing and controls and testing associated
with our clinical candidates, including as it relates to sourcing materials required for such manufacture, or difficulties or delays associated with testing of
our pre-clinical antibody candidates. While we currently do not anticipate any interruptions in our clinical trial supply of drug candidates, it is possible that
the COVID-19 pandemic and response efforts may have
54
an impact in the future on our third-party suppliers and contract manufacturing partners' ability to manufacture our clinical trial supply or source materials
necessary for their manufacture.
We continue to monitor the impact with respect to our clinical trials, including directly or indirectly on enrollment, new, planned clinical trial site openings,
patient visits, and on-site monitoring of our clinical trials and source verification of clinical data required for presentation of clinical data for clinical
candidates, as well as the impact on drug supply and vendors. Over the quarter ended December 31, 2023 and to date, we have observed a low impact on
drug supply, vendors, clinical trial enrollment, patient site visits and a moderate impact on patient monitoring visits as a consequence of the COVID-19
pandemic. Such impacts have included certain patients needing to quarantine and unable to attend hospital visits until the required period of isolation
ended, and study coordinator availability being limited due to shortages of personnel and illness as a result of COVID-19. Adjustments have also been
made to allow remote visits for some patient follow-up, and reduced onsite monitoring by the sponsor or CRO and insufficient source verification of
clinical data required for presentation of clinical data.
The extent to which the pandemic further impacts our business, including our preclinical studies and clinical trials, results of operations and financial
condition will depend on future developments which cannot be predicted with confidence. Such factors include but are not limited to the spread and
potential resurgence of the disease, and global responses to such a resurgence.
Risks Related to the Development and Clinical Testing of Our Antibody Candidates
All of our antibody candidates are in pre-clinical or clinical development. Clinical drug development is a lengthy and expensive process with uncertain
timelines and uncertain outcomes. If clinical trials of our antibody candidates, particularly zenocutuzumab, petosemtamab, MCLA-129 or MCLA-145,
are prolonged or delayed, we or any collaborators may be unable to obtain required regulatory approvals, and therefore be unable to commercialize our
antibody candidates on a timely basis or at all.
To obtain the requisite regulatory approvals to market and sell any of our antibody candidates, we or any collaborator for such candidates must demonstrate
through extensive pre-clinical studies and clinical trials that such candidates are safe, pure and potent in humans. Clinical testing is expensive and can take
many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of pre-clinical
studies and early-stage clinical trials of our antibody candidates may not be predictive of the results of later-stage clinical trials. Antibody candidates in
later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through pre-clinical studies and initial clinical
trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or
adverse safety profiles, notwithstanding promising results in earlier trials. Our future clinical trial results may not be successful.
To date, we have not completed any registrational clinical trials required for the approval of any of our antibody candidates. Although we are conducting
ongoing clinical trials for zenocutuzumab, petosemtamab, MCLA-129, and MCLA-145 and pre-clinical studies for other antibody candidates, we may
experience delays in our ongoing clinical trials and we do not know whether planned clinical trials will begin on time, need to be redesigned, enroll patients
on time or be completed on schedule, if at all. Clinical trials can be delayed, suspended, or terminated for a variety of reasons, including the following:
•
•
•
•
•
•
•
•
delays in or failure to reach agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which can be subject
to extensive negotiation and may vary significantly among different CROs and trial sites;
delays in or failure to recruit suitable patients to participate in a trial;
delays in or failure to establish the appropriate dose and schedule for antibody candidates in clinical trials;
the difficulty in identifying the sub-populations that we are trying to treat in a particular trial, which may delay enrollment and reduce the
power of a clinical trial to detect statistically significant results;
lower than anticipated retention rates of patients in clinical trials;
failure to have patients complete a trial or return for post-treatment follow-up;
clinical sites deviating from trial protocol or dropping out of a trial;
investigator-sponsored studies of our product candidates, including expanded or early access protocols, may identify safety or efficacy
concerns associated with our antibody candidates, or otherwise negatively affect patient enrollment in our ongoing and planned clinical
trials;
55
•
•
•
•
•
•
•
•
•
•
•
•
delays in, inability or failure to add new clinical trial sites;
safety or tolerability concerns could cause us or our collaborators or regulatory authorities, as applicable, to pause, suspend or terminate a
trial if we or our collaborators or regulatory authorities, find that the participants are being exposed to unacceptable health risks or during
evaluation of safety signals;
failure to observe a meaningful clinical benefit;
delays in or failure to obtain regulatory approval or authorizations to commence a trial;
delays in or failure to obtain institutional review board (IRB) or ethics committee approval at each site;
our third-party research contractors failing to comply with regulatory requirements or applicable law, or to meet their contractual
obligations to us in a timely manner, or at all;
changes in regulatory requirements, policies and guidelines;
manufacturing sufficient quantities of our antibody candidate for use in clinical trials;
the quality or stability of an antibody candidate falling below acceptable standards;
changes in the treatment landscape for our target indications that may make our antibody candidates no longer relevant;
third party actions claiming infringement by our antibody candidates in clinical trials outside of the United States and obtaining injunctions
interfering with our progress; and
business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters including earthquakes,
typhoons, floods and fires, epidemics or public health emergencies and U.S. or non-U.S. governmental actions or restrictions related
thereto.
We could encounter delays if a clinical trial is paused, suspended or terminated by us, by the IRBs or ethics committees of the institutions in which such
trials are being conducted, by the Data Review Committee or Data Safety Monitoring Board for such trial or by the FDA, the competent authorities of the
European Economic Area (EEA) countries (the 27 EU member states plus Iceland, Liechtenstein and Norway) and the UK, or other regulatory authorities.
Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with
regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA, EEA competent authorities or other
regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from
using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we experience
delays in the completion of, or termination of, any clinical trial of our antibody candidates, the commercial prospects of our antibody candidates will be
harmed, and our ability to generate product revenues from any of these antibody candidates, if approved, will be delayed. In addition, any delays in
completing our clinical trials will increase our costs, slow down our antibody candidate development and approval process and jeopardize our ability to
commence product sales and generate revenues. Significant clinical trial delays could also allow our competitors to bring products to market before we do
or shorten any periods during which we have the exclusive right to commercialize our antibody candidates and impair our ability to commercialize our
antibody candidates, if approved, and may harm our business and results of operations.
Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, 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 regulatory approval of our antibody candidates.
Clinical trials must be conducted in accordance with the FDA, EEA countries, and other applicable regulatory authorities’ legal requirements, other
regulations or guidelines, and are subject to oversight by these governmental agencies and ethics committees or IRBs at the medical institutions where the
clinical trials are conducted. In addition, clinical trials must be conducted with supplies of our antibody candidates produced under current good
manufacturing practice (cGMP), or similar foreign requirements and other regulations. Furthermore, we rely on CROs and clinical trial sites to ensure the
proper and timely conduct of our clinical trials and while we have agreements governing their committed activities, we have limited influence over their
actual performance. We depend on our collaborators and on medical institutions and CROs to conduct our clinical trials in compliance with good clinical
practice (GCP) requirements. To the extent our collaborators or the CROs fail to enroll participants for our clinical trials, fail to conduct the study to GCP
standards or are delayed for a significant time in the execution of trials, including achieving full enrollment, we may be
56
affected by increased costs, program delays or both, which may harm our business. In addition, clinical trials that are conducted in countries outside the
EEA and the United States may subject us to further delays and expenses as a result of increased shipment costs, additional regulatory requirements and the
engagement of non-EEA and non-U.S. CROs, as well as expose us to risks associated with clinical investigators who are unknown to the FDA or the EEA
competent authorities, and may use different standards of diagnosis, screening and medical care.
In addition, the FDA’s and other regulatory authorities’ policies with respect to clinical trials may change and additional government regulations may be
enacted. For instance, the regulatory landscape related to clinical trials in the EU recently evolved. The EU Clinical Trials Regulation (CTR) which was
adopted in April 2014 and repeals the EU Clinical Trials Directive, became applicable on January 31, 2022. While the EU Clinical Trials Directive required
a separate clinical trial application (CTA) to be submitted in each member state in which the clinical trial takes place, to both the competent national health
authority and an independent ethics committee, the CTR introduces a centralized process and only requires the submission of a single application for multi-
center trials. The CTR allows sponsors to make a single submission to both the competent authority and an ethics committee in each member state, leading
to a single decision per member state. The assessment procedure of the CTA has been harmonized as well, including a joint assessment by all member
states concerned, and a separate assessment by each member state with respect to specific requirements related to its own territory, including ethics rules.
Each member state’s decision is communicated to the sponsor via the centralized EU portal. Once the CTA is approved, clinical study development may
proceed. The CTR foresees a three-year transition period. The extent to which ongoing and new clinical trials will be governed by the CTR varies. Clinical
trials for which an application was submitted (i) prior to January 31, 2022 under the EU Clinical Trials Directive, or (ii) between January 31, 2022 and
January 31, 2023 and for which the sponsor has opted for the application of the EU Clinical Trials Directive remain governed by said Directive until
January 31, 2025. After this date, all clinical trials (including those which are ongoing) will become subject to the provisions of the CTR. Compliance with
the CTR requirements by us, our collaborators and third-party service providers, such as CROs, may impact our developments plans.
It is currently unclear to what extent the UK will seek to align its regulations with the EU. The UK regulatory framework in relation to clinical trials is
derived from existing EU legislation (as implemented into UK law, through secondary legislation).
On January 17, 2022, the UK Medicines and Healthcare products Regulatory Agency (MHRA) launched an eight-week consultation on reframing the UK
legislation for clinical trials and which aimed to streamline clinical trials approvals, enable innovation, enhance clinical trials transparency, enable greater
risk proportionality, and promote patient and public involvement in clinical trials. The UK Government published its response to the consultation on March
21, 2023 confirming that it would bring forward changes to the legislation. These resulting legislative amendments will determine how closely the UK
regulations are aligned with the CTR. A decision by the UK Government not to closely align its regulations with the new approach adopted in the EU may
have an effect on the cost of conducting clinical trials in the UK as opposed to other countries. Under the terms of the Protocol on Ireland/Northern Ireland,
provisions of the CTR which relate to the manufacture and import of investigational medicinal products and auxiliary medicinal products apply in Northern
Ireland. Once the changes brought by the Windsor Framework implemented, this may have further impact on the application of the CTR in Northern
Ireland.
If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies governing clinical trials, our
development plans may be impacted.
Interim, preliminary, and “top-line” data from our clinical trials that we announce or publish from time to time may change as more patient data
become available and are subject to audit and verification procedures that could result in material changes in the final data.
From time to time, we may publish interim, preliminary or “top-line” data from our clinical trials. Interim data from clinical trials that we may complete are
subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available.
Preliminary and top-line data also remain subject to audit and verification procedures that may result in the final data being materially different from the
preliminary data previously published. In addition, we may decide to report interim or preliminary analyses of only certain endpoints (e.g., primary subject
to investigator review) rather than all endpoints (e.g., including secondary subject to central review). As a result, interim, preliminary and top-line data
should be viewed with caution until the final data are available.
Furthermore, the information we choose to publicly disclose regarding a particular study or clinical trial is based on more extensive information, and others
may not agree with what we determine is the material or otherwise appropriate information to disclose. Any information we determine not to disclose may
ultimately be deemed significant with respect to future decisions, conclusions, views, activities, or otherwise regarding a particular antibody candidate or
our business. Others, including regulatory agencies, may not
57
accept or agree with our assumptions, estimates, calculations, conclusions, or analyses or may interpret or weigh the importance of data differently, which
could impact the value of particular programs, the approvability or commercialization of the particular antibody candidates, and our business in general. As
a result, interim, preliminary or top-line data and analyses should be viewed with caution. Adverse differences between preliminary, top-line or interim data
and final data or changes in what is material information regarding the results from a particular study or clinical trial could significantly harm our clinical
development and business prospects and cause volatility in the price of our common shares. If the interim, top-line, or preliminary data that we report differ
from actual or final results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and
commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.
Our antibody candidates may have serious adverse, undesirable or unacceptable side effects which may delay or prevent marketing approval. If such
side effects are identified during the development of our antibody candidates or following approval, if any, we may need to abandon our development of
such antibody candidates, the commercial profile of any approved label may be limited, or we may be subject to other significant negative consequences
following marketing approval, if any.
Undesirable side effects that may be caused by our antibody candidates, whether alone or in combination with other drugs, could 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 regulatory approval by the FDA, the
EMA or other comparable foreign authorities.
In February 2015, we commenced a Phase 1/2 clinical trial in Europe of our most advanced antibody candidate, zenocutuzumab, for the treatment of
various solid tumors, which was amended to treat patients having solid tumors harboring a NRG1 gene fusion. Additionally, in January 2018 we
commenced a Phase 2 clinical trial in Europe and the United States exploring zenocutuzumab, in combination with other agents, in patients with metastatic
breast cancer. Patients treated with zenocutuzumab have experienced adverse reactions that may be related to the treatment with a safety update provided
for zenocutuzumab in October 2023, at the European Society for Medical Oncology (ESMO) Congress 2023, with a safety cut-off date of July 31, 2023. In
May 2018 we commenced a Phase 1/2 clinical trial of our bispecific antibody petosemtamab in patients with solid tumors. Patients treated with
petosemtamab have experienced adverse reactions that may be treatment related, with a safety update provided for petosemtamab in April 2023 at AACR,
with a safety data cutoff date of February 1, 2023, and on January 15, 2021, at ASCO GI, with a safety data cutoff date of September 7, 2020, where safety
events were reported for patients treated with petosemtamab as a single agent across 11 dose levels (5 to 1500mg), and at the AACR-NCI-EORTC Virtual
International Conference on Molecular Targets and Cancer Therapeutics, on October 7-10, 2021, with a data cutoff date of August 9, 2021. In May 2021,
we commenced a Phase 1/2 clinical trial in the United States of our bispecific antibody MCLA-129 in patients with advanced NSCLC and other solid
tumors. Patients treated with MCLA-129 have experienced adverse events, with a safety update provided for MCLA-129 in December 2023 at the ESMO
Asia Congress 2023 held in Singapore, December 1-3. In May 2019, we commenced a Phase 1 clinical trial in the United States of our bispecific antibody
MCLA-145 in patients with solid tumors. Patients treated with MCLA-145 have experienced adverse events that may be related to the treatment, with a
safety update provided for MCLA-145 on December 8-11, 2021 at the 2021 European Society for Medical Oncology-Immuno-Oncology (ESMO-IO)
Congress, with a data cutoff date of July 14, 2021.
We also engage in combination studies of our antibody candidates in combination with other approved therapies, the combination of which may also cause
or be correlated with undesirable side effects not observed in our monotherapy trials that may 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 regulatory approval by the FDA, the EMA or other comparable foreign
authorities. For example, in 2023, we commenced a Phase 1/2 investigation of zenocutuzumab in combination with afatinib in patients having NRG1+
NSCLC and investigation of zenocutuzumab in combination with an androgen deprivation therapy (ADT) in patients with castration resistant prostate
cancer, irrespective of NRG1+ status. We continue to monitoring and evaluate patients enrolled and have observed certain adverse events from patients
receiving the combination of zenocutuzumab in combination with an androgen deprivation therapy including diarrhea, decreased appetite, fatigue,
stomatitis. Side effects associated with abiraterone include mineralocorticoid excess, adrenocortical insufficiency, and hepatotoxicity, and for enzalutamide
include seizure, posterior reversible encephalopathy syndrome (PRES), hypersensitivity, ischemic heart disease, falls and fractures, embryo-fetal toxicity.
Side effects associated with afatinib include diarrhea, bullous and exfoliative skin disorders, interstitial lung disease, hepatic toxicity, gastrointestinal
perforation, keratitis, embryo-fetal toxicity. In 2023, we commenced a Phase 1/2 investigation of petosemtamab in combination with pembrolizumab as a
potential front-line therapy for advanced HNSCC expressing PD-L1 (combined positive score (CPS) > 1). We have observed certain adverse events from
patients receiving the combination of petosemtamab and pembrolizumab, including infusion related reactions, and asthenia. Common side effects with
pembrolizumab when used alone include feeling tired, pain, including pain in muscles, rash, diarrhea, fever, cough, decreased appetite, itching, shortness of
breath, constipation, bones or joints and stomach-area (abdominal) pain, nausea, and low levels of thyroid hormone. In 2022, we commenced a Phase 1/2
investigation of the combination of MCLA-129 with osimertinib, a
58
third generation EGFR TKI, in patients with treatment-naïve EGFR mutant (m) NSCLC and in patients with EGFRm NSCLC that has progressed on
osimertinib. We continue to monitor and evaluate patients enrolled and have observed certain adverse events from patients receiving the combination of
MCLA-129 in combination with osimertinib, including infusion-related reactions, skin toxicity, gastrointestinal events, asthenia, decreased appetite, venous
thromboembolism (VTE, composite term) and treatment-related interstitial lung disease, with additional details on safety reported at the ESMO Asia
Congress 2023 held in Singapore, December 1-3. In addition, osimertinib has warnings and precautions regarding interstitial lung disease, QT prolongation,
cardiomyopathy, keratitis and Stevens-Johnson Syndrome, and toxic epidermal necrolysis; cutaneous vasculitis, aplastic anemia, embryo-fetal toxicity. In
2022, we commenced a Phase 1 investigation of MCLA-145 in combination with pembrolizumab in solid tumors. We continue to monitor and evaluate
patients enrolled and have observed certain adverse events including fatigue, cough, pyrexia, constipation, decreased appetite, dyspnoea, nausea, dizziness
and elevation of liver enzymes.
In each of our clinical trials and investigations of our antibody candidates in combination with approved therapies there may still be important facts about
the safety, efficacy, and risk versus benefit that are not known to us at this time which may negatively impact our ability to develop and commercialize our
antibody candidates as single agents or in combination with other agents. In this regard, we have in the past and may in the future observe serious side
effects ranging from grade 1 to grade 5 across our clinical trials, including patient death, and we have in the past, and may in the future, institute additional
precautionary safety measures such as dosing caps and delays, enhanced monitoring for side effects, and modified patient inclusion and exclusion criteria.
Additional and/or unexpected safety events or our failure to generate additional efficacy data in our clinical trials that support registration could
significantly impact the value of antibody candidates to our business. Many companies in the pharmaceutical and biotechnology industries, including us,
have suffered significant setbacks in late-stage clinical trials or combination trials after achieving encouraging or positive results in early-stage
development. We cannot be certain that we will not face similar setbacks in our ongoing or planned clinical trials. If we or our collaborators fail to produce
positive results in our ongoing or planned clinical trials of our other product candidates, the development timeline and regulatory approval and
commercialization prospects for our product candidates, and, correspondingly, our business, financial condition, results of operations and growth prospects,
would be materially adversely affected.
If results of our trials reveal a high and unacceptable severity and prevalence of adverse events or side effects, including those that may be new or
unexpected, our trials or enrollment could be paused, suspended or terminated and the FDA, EEA competent authorities, or comparable foreign regulatory
authorities could order us to cease further development of or deny approval of our antibody candidates for any or all targeted indications. The drug-related
side effects could affect patient recruitment, investigator engagement and commitment and perception of the clinical candidate or the ability of enrolled
patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and
prospects significantly. Additionally, if any of our antibody candidates receives marketing approval and we or others later identify undesirable or
unacceptable side effects caused by such products, a number of potentially significant negative consequences could result, including:
•
•
•
•
•
•
•
•
regulatory authorities may withdraw approvals of such products and require us to take our approved product off the market;
regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication or field alerts to physicians and
pharmacies;
regulatory authorities may require a medication guide outlining the risks of such side effects for distribution to patients, or that we
implement a risk evaluation and mitigation strategy plan to ensure that the benefits of the product outweigh its risks;
we may be required to change the dose or the way the product is administered, conduct additional clinical trials or change the labeling of the
product;
we may be subject to limitations on how we may promote the product;
sales of the product may decrease significantly;
we may be subject to litigation or product liability claims; and
our reputation may suffer.
59
Any of these events could prevent us, our collaborators or our potential future partners from achieving or maintaining market acceptance of the affected
antibody candidate, if approved, or could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from
generating significant revenue from the sale of our antibody candidates, if approved.
We depend on enrollment of patients in our clinical trials for our antibody candidates. If we are unable to enroll patients in our clinical trials, our
research and development efforts and business, financial condition and results of operations could be materially adversely affected.
Successful and timely completion of clinical trials will require that we enroll a sufficient number of patient candidates. For our Phase 1/2 clinical trial of
zenocutuzumab in solid tumors, we are enrolling up to 250 patients with tumors harboring NRG1 gene fusions (NRG1+). Solid tumors with NRG1 gene
fusions occur infrequently, which could result in slow enrollment of clinical trial participants. For our Phase 2 clinical trial of zenocutuzumab in patients
with CRPC in combinations with an ADT, and patients with NRG1+ NSCLC in combination with afatinib, we have paused enrollment of both cohorts, but
may enroll up to 90 patients. In the Phase 2 clinical trial of MCLA-129, we plan to enroll up to 380 adult patients with solid tumors. In the Phase 1/2
clinical trial of petosemtamab, we plan to enroll up to 360 adult patients with solid tumors. We further anticipate potentially initiating a randomized phase 3
trial of petosemtamab monotherapy, or investigators’ choice of single agent chemotherapy or cetuximab in 2L/3L HNSCC. We anticipate such a trial could
potentially start in mid-2024. We are further developing petosemtamab in combination with pembrolizumab, a PD-1 blocking antibody, investigating this
combination in patients with untreated HNSCC expressing PD-L1 (CPS > 1) to evaluate safety and clinical activity in this population, and we believe
initial safety data from this single arm cohort may support the initiation of a first-line registration trial with this combination. We further plan to initiate a
cohort investigating petosemtamab in 2L CRC patients in 2024. In the Phase 1 clinical trial of MCLA-145, we plan to enroll up to 118 adult patients with
solid tumors. These trials and other trials we conduct may be subject to delays as a result of patient enrollment taking longer than anticipated or patient
withdrawal.
Our clinical trials will also compete with other clinical trials for antibody candidates that are in the same therapeutic areas as our antibody candidates, and
this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may
instead opt to enroll in a trial being conducted by one of our competitors. Because the number of qualified clinical investigators and clinical trial sites is
limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of
patients who are available for our clinical trials at such clinical trial sites.
Patient enrollment depends on many factors, including the size and nature of the patient population, eligibility criteria for the trial, the proximity of patients
to clinical sites, the design of the clinical protocol, the availability of competing clinical trials, the availability of new drugs approved for the indication the
clinical trial is investigating, and clinicians’ and patients’ perceptions as to the potential advantages of the drug being studied in relation to other available
therapies. These factors may make it difficult for us to enroll enough patients to complete our clinical trials in a timely and cost-effective manner. Delays in
the completion of any clinical trial of our antibody candidates will increase our costs, slow down our antibody candidate development and approval
process, delay or potentially jeopardize our ability to commence product sales and generate revenue and harm our reputation and ability to obtain financing.
In addition, some 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
regulatory approval of our antibody candidates.
We may become exposed to costly and damaging liability claims, either when testing our antibody candidates in the clinic or at the commercial stage;
and our product liability insurance may not cover all damages from such claims.
We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing and
use of pharmaceutical products. Currently, we have no products that have been approved for commercial sale; however, the current and future use of
antibody candidates by us and our collaborators in clinical trials, and the sale of any approved products in the future, may expose us to liability claims.
These claims might be made by patients that use the product, healthcare providers, pharmaceutical companies, our collaborators or others selling such
products. Any claims against us, regardless of their merit, could be difficult and costly to defend and could materially adversely affect the market for our
antibody candidates or any prospects for commercialization of our antibody candidates, if approved.
Although the clinical trial process is designed to identify and assess potential side effects, it is always possible that a drug, even after regulatory approval,
may exhibit unforeseen side effects. If any of our antibody candidates were to cause adverse side effects during
60
clinical trials or after approval of the antibody candidate, we may be exposed to substantial liabilities. Physicians and patients may not comply with any
warnings that identify known potential adverse effects and patients who should not use our antibody candidates.
Although we maintain adequate product liability insurance for our antibody candidates, it is possible that our liabilities could exceed our insurance
coverage. We intend to expand our insurance coverage to include the sale of commercial products if we obtain marketing approval for any of our antibody
candidates. However, we may not be able to maintain insurance coverage at a reasonable cost or obtain insurance coverage that will be adequate to satisfy
any liability that may arise. If a successful product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured
liabilities, our assets may not be sufficient to cover such claims and our business operations could be impaired.
Should any of the events described above occur, this could have a material adverse effect on our business, financial condition and results of operations.
The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming and inherently unpredictable, and if we
are ultimately unable to obtain regulatory approval for our antibody candidates, our business will be substantially harmed.
The time required to obtain approval by the FDA and comparable foreign authorities is unpredictable but typically takes many years following the
commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval
policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of an antibody candidate’s clinical
development and may vary among jurisdictions. We have not obtained regulatory approval for any antibody candidate and it is possible that none of our
existing antibody candidates or any antibody candidates we may seek to develop in the future will ever obtain regulatory approval.
Our antibody candidates could fail to receive regulatory approval for many reasons, including the following:
•
•
•
•
•
•
•
•
•
the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials;
we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that an antibody candidate is
safe, pure, potent and/or effective for its proposed indication;
we may be unable to demonstrate that an antibody candidate’s clinical and other benefits outweigh its safety risks;
the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from pre-clinical studies or clinical trials;
the data collected from clinical trials of our antibody candidates, our data monitoring, oversight of our CROs may not be sufficient in
amount or quality to support the submission of a BLA or other submission or to obtain regulatory approval in the United States, the EU or
elsewhere;
the FDA or comparable foreign regulatory authorities may fail to approve the manufacturing processes or facilities of third-party
manufacturers with which we contract for clinical and commercial supplies;
the FDA or comparable foreign regulatory authorities and notified bodies may fail to approve (or to clear or to certify) the companion
diagnostics we contemplate developing with collaborators; and
the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner
rendering our clinical data insufficient for approval.
for instance, the EU pharmaceutical legislation is currently undergoing a complete review process, in the context of the Pharmaceutical
Strategy for Europe initiative, launched by the European Commission in November 2020. The European Commission's proposal for a
revision of several legislative instruments related to medicinal products (including potentially reducing the duration of regulatory
exclusivity and revising the eligibility for expedited pathways) was published on April 26, 2023. The proposed revisions remain to be
agreed and adopted by the European Parliament and European Council. The proposals may be substantially revised before adoption, which
is not anticipated before the end of 2026. The revisions may, however, have a significant impact on the biopharmaceutical industry and our
business in the long term.
61
This lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to market
any of our antibody candidates, which would significantly harm our business, results of operations and prospects. The FDA and other regulatory authorities
have substantial discretion in the approval process, and determining when or whether regulatory approval will be obtained for any of our antibody
candidates. Even if we believe the data collected from clinical trials of our antibody candidates are promising, such data may not be sufficient in quantity or
quality to support approval by the FDA or any other regulatory authority.
In addition, even if we were to obtain approval, regulatory authorities may approve any of our antibody candidates for fewer or more limited indications
than we request, may not approve the price we intend to charge for our products, may grant approval contingent on the performance of costly post-
marketing clinical trials, or may approve an antibody candidate with a label that does not include the labeling claims necessary or desirable for the
successful commercialization of that antibody candidate. Any of the foregoing scenarios could materially harm the commercial prospects for our antibody
candidates and have a material adverse effect on our business, financial condition and results of operations.
Fast Track designation by the FDA for zenocutuzumab and petosemtamab or potential future Fast Track designation of our other antibody candidates
may not actually lead to a faster development or regulatory review or approval process.
We have been granted a Fast Track designation for zenocutuzumab for the treatment of patients with metastatic solid tumors harboring NRG1 gene fusions
that have progressed on standard-of-care therapy and for petosemtamab for the treatment of patients with recurrent or metastatic HNSCC whose disease has
progressed following treatment with platinum-based chemotherapy and an anti-programmed cell death protein 1 (anti-PD-1) antibody, and we may seek
additional Fast Track designations for zenocutuzumab, petosemtamab or for our other antibody candidates. The Fast Track program is intended to expedite
or facilitate the process for reviewing therapeutic candidates that meet certain criteria. Specifically, investigational biologics are eligible for Fast Track
designation if they are intended, alone or in combination with one or more drugs or biologics, to treat a serious or life-threatening disease or condition and
demonstrate the potential to address unmet medical needs for the disease or condition. Fast Track designation applies to the combination of the product
candidate and the specific indication for which it is being studied. The sponsor of a Fast Track candidate has opportunities for more frequent interactions
with the applicable FDA review team during product development and, once a BLA is submitted, the application may be eligible for priority review. With a
Fast Track designation for an antibody candidate, the FDA may consider for review sections of the BLA on a rolling basis before the complete application
is submitted, if the sponsor provides a schedule for the submission of the sections of the BLA, the FDA agrees to accept sections of the BLA and
determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the BLA.
Obtaining a Fast Track designation does not change the standards for product approval but may expedite the development or approval process. Even though
the FDA has granted such designation for zenocutuzumab for the treatment of patients with metastatic solid tumors harboring NRG1 gene fusions that have
progressed on standard-of-care therapy and for petosemtamab for the treatment of patients with recurrent or metastatic HNSCC whose disease has
progressed following treatment with platinum-based chemotherapy and an anti-programmed cell death protein 1 (anti-PD-1) antibody, these designations
may not actually result in faster clinical development or regulatory review or approval. Furthermore, such a designation does not increase the likelihood
that zenocutuzumab or any other antibody candidate that may be granted Fast Track designation will receive marketing approval in the United States.
Breakthrough Therapy designations by the FDA for zenocutuzumab and any potential future product candidate may not lead to a faster development
or regulatory review or approval process, and it does not increase the likelihood that the product candidate will receive FDA approval.
We have been granted a Breakthrough Therapy designations for zenocutuzumab for the treatment of patients with advanced unresectable or metastatic
NRG1 fusion (NRG1+) pancreatic cancer following progression with prior systemic therapy or who have no satisfactory alternative treatment options and
for zenocutuzumab for the treatment of patients with advanced unresectable or metastatic NRG1+ non-small cell lung cancer (NSCLC), following
progression with prior systemic therapy, and we may seek additional Breakthrough Therapy designations for zenocutuzumab or for our other antibody
candidates, or the comparable designations in foreign jurisdictions, where we believe the clinical data support such designations.
A "Breakthrough Therapy" is defined as a drug or biologic that is intended, alone or in combination with one or more other drugs or biologics, to treat a
serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the product candidate 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 product candidates 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
62
efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Drugs and biologics designated as
Breakthrough Therapies also receive the same benefits associated with Fast Track designation, including eligibility for rolling review of a submitted BLA,
if the relevant criteria are met. Designation as a Breakthrough Therapy is within the discretion of the FDA.
Accordingly, even if we believe that 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 product candidates considered for approval under conventional FDA procedures and it would
not assure ultimate approval by the FDA.
In addition, even if one or more of our product candidates qualify as Breakthrough Therapies and have received such designation, the FDA may later
decide that the product candidate no longer meets the conditions for qualification and rescind the designation.
We may attempt to secure approval from the FDA through the use of the accelerated approval pathway. If we are unable to obtain such approval, we
may be required to conduct additional pre-clinical studies or clinical trials beyond those that we contemplate, which could increase the expense of
obtaining, and delay the receipt of, necessary regulatory approvals. Even if we receive accelerated approval from the FDA, if our confirmatory trials do
not verify clinical benefit, or if we do not comply with rigorous post-marketing requirements, the FDA may seek to withdraw any accelerated approval
we have obtained.
We plan to seek for zenocutuzumab and may in the future for other clinical candidates seek accelerated approval our product candidates. Under the
accelerated approval program, the FDA may grant accelerated approval to a product candidate designed to treat a serious or life-threatening condition that
provides meaningful therapeutic benefit over available therapies upon a determination that the product candidate has an effect on a surrogate endpoint or
intermediate clinical endpoint that is reasonably likely to predict clinical benefit. The FDA considers a clinical benefit to be a positive therapeutic effect
that is clinically meaningful in the context of a given disease, such as irreversible morbidity or mortality. 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. An intermediate clinical endpoint is a clinical endpoint that can be measured earlier than an effect on
irreversible morbidity or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit.
The accelerated approval pathway may be used in cases in which the advantage of a product candidate over available therapy may not be a direct
therapeutic advantage, but is a clinically important improvement from a patient and public health perspective. If granted, accelerated approval is usually
contingent on the sponsor’s agreement to conduct, in a diligent manner, additional confirmatory studies to verify and describe the drug’s clinical benefit. If
such post-approval studies fail to confirm the drug’s clinical benefit or are not completed in a timely manner, the FDA may withdraw its approval of the
drug on an expedited basis. In addition, in December 2022, President Biden signed an omnibus appropriations bill to fund the U.S. government through
fiscal year 2023. Included in the omnibus bill is the Food and Drug Omnibus Reform Act of 2022, which among other things, provided FDA new statutory
authority to mitigate potential risks to patients from continued marketing of ineffective drugs previously granted accelerated approval. Under these
provisions, among other things, the FDA may require a sponsor of a product seeking accelerated approval to have a confirmatory trial underway prior to
such approval being granted.
Prior to seeking accelerated approval for any of our product candidates, we intend to seek feedback from the FDA and will otherwise evaluate our ability to
seek and receive accelerated approval. There can be no assurance that after our evaluation of the feedback and other factors we will decide to pursue or
submit a BLA for accelerated approval or any other form of expedited development, review or approval. Furthermore, if we decide to submit an application
for accelerated approval for our product candidates, there can be no assurance that such application will be accepted or that any expedited development,
review or approval will be granted on a timely basis, or at all. The FDA or other comparable foreign regulatory authorities could also require us to conduct
further studies prior to considering our application or granting approval of any type. A failure to obtain accelerated approval or any other form of expedited
development, review or approval for our product candidate would result in a longer time period to commercialization of such product candidate, if any,
could increase the cost of development of such product candidate and could harm our competitive position in the marketplace.
Even if our antibody candidates obtain regulatory approval, we will be subject to ongoing obligations and continued regulatory review, which may
result in significant additional expense. Additionally, our antibody candidates, if approved, could be subject to labeling and other restrictions and
market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our
products.
63
Any regulatory approvals that we may receive for our antibody candidates will require the submission of reports to regulatory authorities and surveillance
to monitor the safety and efficacy of the product candidate, may contain significant limitations related to use restrictions for specified age groups, warnings,
precautions or contraindications, and may include burdensome post-approval study or risk management requirements. For example, the FDA may require a
Risk Evaluation and Mitigation Strategy in order to approve our antibody candidates, which could entail requirements for a medication guide, physician
training and communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk
minimization tools. Similar risk management measures may be required by foreign regulatory authorities. In addition, if the FDA or foreign regulatory
authorities approve our antibody candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising,
promotion, import, export and recordkeeping for our product candidates will be subject to extensive and ongoing regulatory requirements. These
requirements include submissions of safety and other post-marketing information and reports, registration, as well as on-going compliance with cGMPs or
similar foreign requirements, and GCPs for any clinical trials that we conduct following approval. In addition, manufacturers of drug products and their
facilities are subject to continual review and periodic, unannounced inspections by the FDA and other regulatory authorities for compliance with cGMP or
similar foreign regulations and standards.
If we or a regulatory authority discover previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or
problems with the facilities where the product is manufactured, a regulatory authority may impose restrictions on that product, the manufacturing facility or
us, including requiring recall or withdrawal of the product from the market or suspension of manufacturing. In addition, failure to comply with FDA and
other comparable foreign regulatory requirements may subject our company to administrative or judicially imposed sanctions, including:
•
•
•
•
•
•
•
•
•
•
•
delays in or the rejection of product approvals;
restrictions on our ability to conduct clinical trials, including full or partial clinical holds on ongoing or planned trials;
restrictions on the products, manufacturers or manufacturing process;
warning or untitled letters;
civil and criminal penalties;
injunctions;
suspension or withdrawal of regulatory approvals;
product seizures, detentions or import bans;
voluntary or mandatory product recalls and publicity requirements;
total or partial suspension of production; and
imposition of restrictions on operations, including costly new manufacturing requirements.
The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue and could
require us to expend significant time and resources in response and could generate negative publicity.
The FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could prevent, limit or delay
regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or
policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, and we may not achieve
or sustain profitability.
We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action,
either in the United States or abroad.
We may not be successful in our efforts to use and expand our Biclonics® technology platform to build a pipeline of antibody candidates or to use our
Triclonics® technology platform to build a pipeline of trispecific antibody candidates.
A key element of our strategy is to use and expand our Biclonics® technology platform to build a pipeline of antibody candidates and progress these
antibody candidates through clinical development for the treatment of a variety of different types of diseases. Although
64
our research and development efforts to date have resulted in a pipeline of antibody candidates directed at various cancers, we may not be able to develop
antibody candidates that are safe and effective.
Another important element of our strategy is to develop, use and exploit our Triclonics® technology platform to build a pipeline of trispecific antibody
candidates and collaborate with third parties in potentially researching and developing these trispecific antibody candidates through pre-clinical and clinical
development for the treatment of a variety of different types of diseases. Although our research and development efforts to date have resulted in proof of
concept pre-clinical candidates, we may not be able to develop or monetize these trispecific antibody candidates or demonstrate in the clinic that they are
safe and effective. Even if we are successful in continuing to build our bispecific and trispecific pipelines, the potential antibody candidates that we identify
may not be suitable for clinical development, including as a result of being shown to have harmful side effects or other characteristics that indicate that they
are unlikely to be products that will receive marketing approval and achieve market acceptance. If we do not continue to successfully develop and begin to
commercialize our bispecific antibody candidates or if we do not successfully develop, collaborate, license or begin to commercialize our trispecific
antibody candidates, we will face difficulty in obtaining product revenues in future periods, which could result in significant harm to our financial position
and adversely affect our share price.
Even if we obtain marketing approval of any of our antibody candidates in a major pharmaceutical market such as the United States or the EU, we may
never obtain approval or commercialize our products in other major markets, which would limit our ability to realize their full market potential.
In order to market any products in a country or territory, we must establish and comply with numerous and varying regulatory requirements of such
countries or territories regarding safety and efficacy. Clinical trials conducted in one country may not be accepted by regulatory authorities in other
countries, and regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. Approval procedures vary
among countries and can involve additional product testing and validation and additional administrative review periods. Seeking regulatory approvals in all
major markets could result in significant delays, difficulties and costs for us and may require additional pre-clinical studies or clinical trials which would be
costly and time consuming. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of our products
in those countries. Satisfying these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. In addition,
our failure to obtain regulatory approval in any country may delay or have negative effects on the process for regulatory approval in other countries. We
currently do not have any antibody candidates approved for sale in any jurisdiction, whether in the Netherlands, the United States or any other international
markets, and we do not have experience in obtaining regulatory approval in international markets. If we fail to comply with regulatory requirements in
international markets or to obtain and maintain required approvals, our target market will be reduced and our ability to realize the full market potential of
our products, if any, will be harmed.
Due to our limited resources and access to capital, we must, and have in the past decided to, prioritize development of certain antibody candidates over
other potential candidates. These decisions may prove to have been wrong and may adversely affect our revenues.
Because we have limited resources and access to capital to fund our operations, we must decide which antibody candidates to pursue and the amount of
resources to allocate to each. Our decisions concerning the allocation of research, collaboration, management and financial resources toward particular
compounds, antibody candidates or therapeutic areas may not lead to the development of viable commercial products and may divert resources away from
better opportunities. Similarly, our decisions to delay, terminate or collaborate with third parties in respect of certain antibody development programs may
also prove not to be optimal and could cause us to miss valuable opportunities. If we make incorrect determinations regarding the market potential of our
antibody candidates or misread trends in the biopharmaceutical industry, in particular for our lead antibody candidates, our business, financial condition
and results of operations could be materially adversely affected.
Because we are subject to environmental, health and safety laws and regulations, we may become exposed to liability and substantial expenses in
connection with environmental compliance or remediation activities which may adversely affect our business and financial condition.
Our operations, including our research, development, testing and manufacturing activities, are subject to numerous environmental, health and safety laws
and regulations. These laws and regulations govern, among other things, the importation, storage, controlled use, handling, release and disposal of, and the
maintenance of a registry for, hazardous materials and biological materials, such as chemical solvents, human cells, animal byproducts, genetically
modified organisms, carcinogenic compounds, mutagenic compounds and compounds that have a toxic effect on reproduction, laboratory procedures and
exposure to blood-borne pathogens. If we fail to
65
comply with such laws and regulations, or fail to obtain or maintain relevant permits, we could be subject to fines or other sanctions or work stoppages,
which could have a material adverse effect on our business, financial condition and results of operations.
As with other companies engaged in activities similar to ours, we face a risk of environmental liability inherent in our current and historical activities,
including liability relating to releases of or exposure to hazardous or biological materials. Environmental, health and safety laws and regulations are
becoming more stringent. We may be required to incur substantial expenses in connection with future environmental compliance or remediation activities,
in which case, our production and development efforts may be interrupted or delayed and our financial condition and results of operations may be
materially adversely affected.
Our employees, independent contractors, principal investigators, CROs, consultants, vendors and collaborators may engage in misconduct or other
improper activities, including noncompliance with applicable law, regulatory standards and requirements, which could have a material adverse effect
on our business.
We are exposed to the risk that our employees, independent contractors, principal investigators, CROs, consultants, vendors and collaborators may engage
in fraudulent conduct or other illegal activities. Misconduct by these parties could include fraudulent, intentional, reckless and/or negligent conduct or
unauthorized activities that violate: (i) the regulations of the FDA and other regulatory authorities, including those laws that require the reporting of true,
complete and accurate information to such authorities; (ii) manufacturing standards; (iii) federal and state data privacy, security, fraud and abuse and other
healthcare laws and regulations in the United States and abroad; (iv) laws that require the reporting of true, complete and accurate financial information and
data; or (v) their representations or commitments to us regarding their capabilities and performance under existing or future agreements. Specifically, sales,
marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct,
kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and
promotion, sales commission, customer incentive programs and other business arrangements. Activities subject to these laws could also involve the
improper use or misrepresentation of information obtained in the course of clinical trials or creating fraudulent data in our pre-clinical studies or clinical
trials, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct by
employees and other third parties, 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 comply with such
laws or regulations. Additionally, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred.
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, disgorgements, possible exclusion from participation in Medicare, Medicaid and other U.S. federal healthcare programs, individual imprisonment,
other sanctions, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could
adversely affect our ability to operate our business and our results of operations. Additionally, we are subject to the risk that misrepresentations regarding
independent contractors, principal investigators, CROs, consultants, vendors and collaborators’ capabilities and performance under existing or future
agreements may lead us to rely upon them for important strategic or operational matters, which could have a significant adverse impact on our business and
results of operations.
Our research and development activities could be affected or delayed as a result of possible restrictions on animal testing.
Certain laws and regulations require us to test our antibody candidates on animals before initiating clinical trials involving humans. Animal testing
activities have been the subject of controversy and adverse publicity. Animal rights groups and other organizations and individuals have attempted to stop
animal testing activities by pressing for legislation and regulation in these areas and by disrupting these activities through protests and other means. To the
extent the activities of these groups are successful, our research and development activities may be interrupted, delayed or become more expensive.
Risks Related to Regulatory Approval of Our Antibody Candidates
Enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our antibody candidates
and may affect the prices we may set. The successful commercialization of our antibody candidates will depend in part on the extent to which
governmental authorities and health insurers establish adequate coverage and reimbursement levels and pricing policies.
In the United States, the EU, and other foreign jurisdictions, there have been, and we expect there will continue to be, a number of legislative and
regulatory changes and proposed changes to the healthcare system that could affect our future results of operations. In particular, there have been and
continue to be a number of initiatives at the United States federal and state levels that seek to reduce
66
healthcare costs and improve the quality of healthcare. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the
Health Care and Education Reconciliation Act (collectively the ACA) was enacted, which substantially changed the way healthcare is financed by both
governmental and private insurers. Among the provisions of the ACA, those of greatest importance to the pharmaceutical and biotechnology industries
include the following:
•
•
•
•
•
•
•
•
•
an annual, non-deductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents, which is
apportioned among these entities according to their market share in certain government healthcare programs;
a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 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;
an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the
average manufacturer price for branded and generic drugs, respectively;
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;
extension of a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed
care organizations;
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 the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;
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 (CMS) to test innovative
payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending.
Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme
Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA.
In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. These changes include the
American Rescue Plan Act of 2021, which eliminated the statutory Medicaid drug rebate cap beginning January 1, 2024. The rebate was previously capped
at 100% of a drug's average manufacturer price. Moreover, payment methodologies, including payment for companion diagnostics, may be subject to
changes in healthcare legislation and regulatory initiatives. In addition, recently there has been heightened governmental scrutiny over the manner in which
manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted 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. Most recently, in August 2022, the Inflation Reduction Act of 2022, or IRA, was
signed into law. Among other things, the IRA requires manufacturers of certain drugs to engage in price negotiations with Medicare (beginning in 2026),
with prices that can be negotiated subject to a cap; imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace
inflation (first due in 2023); and replaces the Part D coverage gap discount program with a new discounting program (beginning 2025). The IRA permits
the Secretary of the Department of Health and Human Services (HHS) to implement many of these provisions through guidance, as opposed to regulation,
for the initial years. HHS has and will continue to issue and update guidance as these programs are implemented. On August 29, 2023, HHS announced the
list of the first ten drugs that will be subject to price negotiations, although the Medicare drug price negotiation program is currently subject to legal
challenges. In addition, in response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining
three new models for testing by the Center for Medicare and Medicaid Innovation which will be evaluated on their ability to lower the cost of drugs,
promote accessibility, and improve quality of care. It is unclear whether the models will be utilized in any health reform measures in the future.
67
We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that the U.S. federal
government will pay for healthcare products and services, which could result in reduced demand for our antibody candidates or additional pricing
pressures.
Individual states in the United States have also become increasingly active in passing legislation and implementing 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.
Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, results of operations, financial
condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what
pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate
demand for any future products or put pressure on our product pricing, which could negatively affect our business, results of operations, financial condition
and prospects.
In the EU, similar political, economic and regulatory developments may affect our ability to profitably commercialize any future products. In addition to
continuing pressure on prices and cost containment measures, legislative developments at the EU or member state level may result in significant additional
requirements or obstacles that may increase our operating costs. The delivery of healthcare in the EU, including the establishment and operation of health
services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than EU, law and policy. National governments
and health service providers have different priorities and approaches to the delivery of health care and the pricing and reimbursement of products in that
context. In general, however, the healthcare budgetary constraints in most EU member states have resulted in restrictions on the pricing and reimbursement
of medicines by relevant health service providers. Coupled with ever-increasing EU and national regulatory burdens on those wishing to develop and
market products, this could prevent or delay marketing approval of our antibody candidates, restrict or regulate post-approval activities and affect our
ability to commercialize any products for which we obtain marketing approval. In international markets, reimbursement and healthcare payment systems
vary significantly by country, and many countries have instituted price ceilings on specific products and therapies.
In the EU, similar developments may affect our ability to profitably commercialize our product candidates, if approved. On December 13, 2021, Regulation
No 2021/2282 on Health Technology Assessment (HTA) amending Directive 2011/24/EU, was adopted. While the Regulation entered into force in January
2022, it will only begin to apply from January 2025 onwards, with preparatory and implementation-related steps to take place in the interim. Once
applicable, it will have a phased implementation depending on the concerned products. The Regulation intends to boost cooperation among EU member
states in assessing health technologies, including new medicinal products, and provide the basis for cooperation at the EU level for joint clinical
assessments in these areas. It will permit EU member states to use common HTA tools, methodologies, and procedures across the EU, working together in
four main areas, including joint clinical assessment of the innovative health technologies with the highest potential impact for patients, joint scientific
consultations whereby developers can seek advice from HTA authorities, identification of emerging health technologies to identify promising technologies
early, and continuing voluntary cooperation in other areas. Individual EU member states will continue to be responsible for assessing non-clinical (e.g.,
economic, social, ethical) aspects of health technology, and making decisions on pricing and reimbursement.
Finally, policies of the individual government agencies, including the FDA or similar regulatory authorities, may change and additional government
regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we or our collaborators are slow or unable to
adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or our collaborators are not able to maintain regulatory
compliance, our antibody candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability, which
would adversely affect our business.
68
If we are required by the FDA or similar authorities to obtain approval (or clearance, or certification) of a companion diagnostic test in connection
with approval of any of our antibody candidates, and we do not obtain or face delays in obtaining approval (or clearance, or certification) of a
diagnostic device, we will not be able to commercialize such product candidate and our ability to generate revenue will be materially impaired.
If safe and effective use of any of our antibody candidates depends on a diagnostic that is not otherwise commercially available, then the FDA may require
approval or clearance of that diagnostic, known as a companion diagnostic, at the same time that the FDA approves our antibody candidates, if at all or as a
post-marketing commitment. According to FDA guidance, if the FDA determines that a companion diagnostic device is essential to the safe and effective
use of a novel therapeutic product or indication, the FDA generally will not approve the therapeutic product or new therapeutic product indication if the
companion diagnostic is not also approved or cleared for that indication. If a satisfactory companion diagnostic is not commercially available, we may be
required to develop or obtain one that would be subject to regulatory approval requirements. The process of obtaining or creating such diagnostics is time
consuming and costly and associated with numerous risks and uncertainties.
Companion diagnostics are developed in conjunction with clinical programs for the associated product and are subject to regulation as medical devices by
the FDA and comparable regulatory authorities, and, to date, the FDA has generally required premarket approval of companion diagnostics labeled for use
with cancer therapies. The approval of a companion diagnostic as part of the therapeutic product’s labeling limits the use of the therapeutic product to only
those patients who express the specific genetic alteration that the companion diagnostic was developed to detect.
If the FDA or a comparable regulatory authority requires approval (or clearance, or certification) of a companion diagnostic for any of our antibody
candidates, whether before or after such candidate obtains marketing approval, difficulties may be encountered in developing and obtaining approval for
such antibody candidate. Any delay or failure by us or third-party collaborators to develop or obtain regulatory approval (or clearance, or certification) of a
companion diagnostic could delay or prevent approval or continued marketing of such antibody candidate.
We may also experience delays in developing a sustainable, reproducible and scalable manufacturing process for the companion diagnostic or in
transferring that process to commercial partners or negotiating insurance reimbursement plans, all of which may prevent us from completing our clinical
trials or commercializing our product candidate, if approved, on a timely or profitable basis, if at all.
Approval, clearance or certification of companion diagnostics may be subject to further legislative or regulatory reforms notably in the EU. On May 25,
2017, the new In Vitro Medical Devices Regulation (2017/746) (IVDR) entered into force. The IVDR repeals and replaces the EU In Vitro Diagnostic
Medical Devices Directive. Unlike directives, which must be implemented into the national laws of the EEA countries, regulations are directly applicable,
i.e., without the need for adoption of EEA countries laws implementing them, in all EEA countries and are intended to eliminate current differences in the
regulation of medical devices among EEA countries. The IVDR, among other things, is intended to establish a uniform, transparent, predictable and
sustainable regulatory framework across the EEA for medical devices and ensure a high level of safety and health while supporting innovation. The IVDR
became applicable on May 26, 2022. However, on October 14, 2021, the European Commission proposed a “progressive” roll-out of the IVDR to prevent
disruption in the supply of in vitro diagnostic medical devices. The European Parliament and Council adopted the proposed Regulation on December 15,
2021. Therefore, the IVDR has applied since May 26, 2022 but there is a tiered system extending the grace period for many devices (depending on their
risk classification) before they have to be fully compliant with the Regulation.
The regulation of companion diagnostics is subject to further requirements since the IVDR became applicable and introduced a new classification system
for companion diagnostics which are now specifically defined as diagnostic tests that support the safe and effective use of a specific medicinal product, by
identifying patients that are suitable or unsuitable for treatment. Companion diagnostics will have to undergo a conformity assessment by a notified body.
Before it can issue an EU certificate, the notified body must seek a scientific opinion from the EMA on the suitability of the companion diagnostic to the
medicinal product concerned if the medicinal product falls exclusively within the scope of the centralized procedure for the authorization of medicines, or
the medicinal product is already authorized through the centralized procedure, or a marketing authorization application for the medicinal product has been
submitted through the centralized procedure. For other substances, the notified body can seek the opinion from national competent authorities or the EMA.
These modifications may make it more difficult and costly for us to obtain regulatory clearances, approvals or certifications for our companion diagnostics
or to manufacture, market or distribute our products after clearance, approval or certification is obtained.
69
Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain
or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a
timely manner or at all, which could negatively impact our business.
The ability of the FDA and foreign regulatory authorities to review and or approve new products can be affected by a variety of factors, including
government budget and funding levels, statutory, regulatory, and policy changes, the FDA’s or foreign regulatory authorities’ ability to hire and retain key
personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s or foreign regulatory authorities’ ability to perform
routine functions. Average review times at the FDA and foreign regulatory authorities have fluctuated in recent years as a result. In addition, government
funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and
unpredictable. Disruptions at the FDA and other agencies, such as the EMA following its relocation to Amsterdam and resulting staff changes, may also
slow the time necessary for new drugs and biologics to be reviewed and/or approved by necessary government agencies, which would adversely affect our
business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have
had to furlough critical FDA employees and stop critical activities.
Separately, in response to the COVID-19 pandemic, the FDA postponed most inspections of domestic and foreign manufacturing facilities at various
points. Even though the FDA has since resumed standard inspection operations, any resurgence of the virus or emergence of new variants may lead to
inspectional or administrative delays. If a prolonged government shutdown occurs, or if global health concerns prevent the FDA or other regulatory
authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other
regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.
We may be subject to healthcare laws, regulation and enforcement; our failure to comply with these laws could harm our results of operations and
financial conditions.
Although we do not currently have any products on the market, if we obtain FDA approval for any of our antibody candidates and begin commercializing
those products in the United States, our operations may be directly, or indirectly through our customers and third-party payors, subject to various U.S.
federal and state healthcare laws and regulations, including, without limitation, the U.S. federal Anti-Kickback Statute. Healthcare providers, physicians
and others play a primary role in the recommendation and prescription of any products for which we obtain marketing approval. These laws may impact,
among other things, our proposed sales, marketing and education programs and constrain our financial arrangements and relationships with healthcare
providers, physicians and other parties through which we market, sell and distribute our products for which we obtain marketing approval. In addition, we
may be subject to additional healthcare, statutory and regulatory requirements and enforcement by foreign regulatory authorities in jurisdictions in which
we conduct our business. The laws that may affect our ability to operate include:
•
•
•
the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly and willfully soliciting,
offering, receiving or paying any remuneration (including any kickback, bribe, or certain rebate), directly or indirectly, overtly or covertly,
in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease, order or recommendation of, any good,
facility, item or service, for which payment may be made, in whole or in part, under U.S. federal and state healthcare programs such as
Medicare and Medicaid; 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;
the U.S. federal false claims and civil monetary penalties laws, including the civil False Claims Act, which, among other things, impose
criminal and civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities for, among other things,
knowingly presenting, or causing to be presented, to the U.S. federal government, claims for payment or approval that are false or
fraudulent, knowingly making, using or causing to be made or used, a false record or statement material to a false or fraudulent claim, or
from knowingly making a false statement to avoid, decrease or conceal an obligation to pay money to the U.S. federal government. In
addition, the government may assert that a claim including items and services resulting from a violation of the U.S. federal Anti-Kickback
Statute constitutes a false or fraudulent claim for purposes of the False Claims Act;
the U.S. federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) which imposes criminal and civil liability for, among
other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, or
knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement, in connection with
the delivery of, or payment for, healthcare benefits, items or services;
70
similar to the U.S. federal 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;
the FD&C Act which prohibits, among other things, the adulteration or misbranding of drugs, biologics and medical devices;
the U.S. federal legislation commonly referred to as Physician Payments Sunshine Act, enacted as part of the ACA, and its implementing
regulations, which requires certain manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare,
Medicaid, or the Children’s Health Insurance Program to report annually to the CMS information related to certain payments and other
transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain other health care
professionals including physician assistants and nurse practitioners, and teaching hospitals, as well as ownership and investment interests
held by the physicians described above and their immediate family members;
analogous state laws and regulations, including: state anti-kickback and false claims laws, which may apply to our business practices,
including but not limited to, research, distribution, sales and marketing arrangements and claims involving healthcare items or services
reimbursed by any third-party payor, including private insurers; state laws that require pharmaceutical companies to comply with the
pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal
government, or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; and state laws and
regulations that require drug manufacturers to file reports relating to pricing and marketing information, and that require the tracking and
reporting of gifts and other remuneration and items of value provided to healthcare professionals and entities; and
European and other foreign law equivalents of each of the laws, including reporting requirements detailing interactions with and payments
to healthcare providers.

Ensuring that our internal operations and future business arrangements with third parties comply with applicable healthcare laws and regulations could
involve substantial costs. It is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes,
regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in
violation of any of the laws described above or any other governmental laws and regulations that may apply to us, we may be subject to significant
penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from U.S. government funded healthcare programs, such as
Medicare and Medicaid, disgorgement, individual imprisonment, contractual damages, reputational harm, diminished profits, reporting obligations and
oversight if we become subject to a corporate integrity agreement or other agreement, and the curtailment or restructuring of our operations. If any of the
physicians or other providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, they may be subject to
criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs and imprisonment. If any of the above occur,
it could adversely affect our ability to operate our business and our results of operations. Further, defending against any such actions can be costly, time-
consuming and may require significant personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought
against us, our business may be impaired.
We face potential liability related to the privacy of health or other personal information we obtain from clinical trials sponsored by us or our
collaborators, from research institutions, and directly from individuals.
Most health care providers, including research institutions from which we or our collaborators obtain patient health information, are subject to privacy and
security regulations promulgated under HIPAA, as amended by HITECH. HIPAA imposes privacy, security and data breach reporting obligations with
respect to individually identifiable health information upon “covered entities” (health plans, health care clearinghouses and certain health care providers),
and their respective “business associates” (individuals or entities that create, receive, maintain or transmit individually identifiable health information in
connection with providing a service for or on behalf of a covered entity, as well as their covered subcontractors). Entities that are found to be in violation of
HIPAA as the result of a breach of unsecured PHI, a complaint about privacy practices, or an audit by HHS, may be subject to significant civil, criminal
and administrative fines and penalties and/or additional reporting and oversight obligations. Any person may be prosecuted under HIPAA’s criminal
provisions either directly or under aiding-and-abetting or conspiracy principles. Consequently, depending on the facts and circumstances, we could face
substantial criminal penalties if we knowingly receive individually identifiable health information from a HIPAA-covered health care provider or research
institution that has not satisfied HIPAA’s requirements for the disclosure of such information.
71
In addition, we may maintain sensitive personally identifiable information, including health information, that we receive throughout the clinical trial
process, in the course of our research collaborations, and directly from individuals (or their healthcare providers) who enroll in our patient assistance
programs. Even when HIPAA does not apply, according to the Federal Trade Commission (FTC), failing to take appropriate steps to keep consumers’
personal information secure constitutes unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act.
The FTC has authority to initiate enforcement actions against entities that mislead customers about HIPAA compliance, make deceptive statements about
privacy and data sharing in privacy policies, fail to limit third-party use of personal health information, fail to implement policies to protect personal health
information or engage in other unfair practices that harm customers or that may violate Section 5(a) of the FTC Act. The FTC expects a company’s data
security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its
business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered sensitive
data that merits stronger safeguards. Additionally, federal and state consumer protection laws are increasingly being applied by FTC and states’ attorneys
general to regulate the collection, use, storage, and disclosure of personal or personally identifiable information, through websites or otherwise, and to
regulate the presentation of website content. The FTC’s guidance for appropriately securing consumers’ personal information is similar to what is required
by the HIPAA Security Rule. As such, we, our collaborators, research institutions, health care providers and other entities that provide personally
identifiable information to us may be subject to state information security laws, and state laws requiring notification of affected individuals and state
regulators in the event of a breach of personal information, which is a broader class of information than the health information protected by HIPAA.
The United States and global data protection landscape is rapidly evolving, and we may be affected by or subject to new or amended laws and regulations
in the future. Certain states have also adopted privacy and security laws and regulations governing the privacy, processing and protection of personal
information. For example, the CCPA went into effect on January 1, 2020. The CCPA, among other things, creates data privacy obligations for covered
companies and provides individual privacy rights to California residents, including the right to delete and to opt out of certain disclosures of their
information. The CCPA also creates a private right of action with statutory damages for certain data breaches, and has increased the risks associated with a
data breach. Although the law includes limited exceptions, including for “protected health information” maintained by a covered entity or business
associate, it may regulate or impact our processing of certain personal information depending on the context. Further, the California Privacy Rights Act
(CPRA) generally went into effect on January 1, 2023. The CPRA significantly amends the CCPA and imposes additional data protection obligations on
covered businesses, including additional consumer rights, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses
of sensitive data. It also creates a new California data protection agency authorized to issue substantive regulations and which could result in increased
privacy and information security enforcement. Additional compliance investment and potential business process changes may also be required.
Similar laws have been proposed in other states and at the federal level, reflecting a trend toward more stringent privacy legislation in the United States.
The enactment of such laws could have potentially conflicting requirements that would make compliance challenging. In the event that we are subject to or
affected by domestic privacy and data protection laws, any liability from failure to comply with the requirements of these laws could adversely affect our
financial condition, our ability to operate in certain jurisdictions and our reputation.
Our and our collaborators’ clinical trial programs and research collaborations outside the U.S. may implicate international data protection laws, including,
in the Europe Economic Area (EEA), the GDPR, UK GDPR and local laws further implementing or supplementing the GDPR. The GDPR imposes more
stringent operational requirements for processors and controllers of personal data including requirements for such companies to be able to ensure and be
able to demonstrate compliance with the GDPR. If our or our collaborators’ privacy or data security measures fail to comply with the GDPR requirements,
we may be subject to litigation, regulatory investigations, enforcement notices requiring us to change the way we use personal data and/or fines of up to
€20 million or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher. In addition to statutory enforcement, a
non-compliance can lead to compensation claims by affected individuals, negative publicity and a potential loss of business.
Among other requirements, the GDPR regulates transfers of personal data subject to the GDPR to third countries that have not been found to provide
adequate protection to such personal data, including the United States, and the efficacy and longevity of current transfer mechanisms between the EEA and
the United States remains uncertain. Such transfers need to be legitimized by a valid transfer mechanism under the GDPR. Case law from the Court of
Justice of the European Union (CJEU) states that reliance on the standard contractual clauses - a standard form of contract approved by the European
Commission as an adequate personal data transfer mechanism - alone may not necessarily be sufficient in all circumstances and that transfers must be
assessed on a case-by-case basis. On October 7, 2022, President Biden signed an Executive Order on ‘Enhancing Safeguards for United States Intelligence
Activities’
72
which introduced new redress mechanisms and binding safeguards to address the concerns raised by the CJEU in relation to data transfers from the EEA to
the United States and which formed the basis of the new EU-US Data Privacy Framework (DPF), as released on December 13, 2022. The European
Commission adopted its Adequacy Decision in relation to the DPF on July 10, 2023, rendering the DPF effective as a GDPR transfer mechanism to U.S.
entities self-certified under the DPF. The DPF also introduced a new redress mechanism for EU citizens which addresses a key concern in the previous
CJEU judgments and may mean transfers under standard contractual clauses are less likely to be challenged in future. We currently rely on the EU standard
contractual clauses and the UK Addendum to the EU standard contractual clauses as relevant to transfer personal data outside the EEA and the UK,
including to the United States, with respect to both intragroup and third party transfers. We expect the existing legal complexity and uncertainty regarding
international personal data transfers to continue. In particular, we expect the DPF Adequacy Decision to be challenged and international transfers to the
United States and to other jurisdictions more generally to continue to be subject to enhanced scrutiny by regulators. As a result, we may have to make
certain operational changes and implement revised standard contractual clauses and other relevant documentation for existing data transfers arrangements
within required time frames.
Further, following the withdrawal of the UK from the EU on January 31, 2020, and the expiration of the transition period, from January 1, 2021, we have
had to comply with the GDPR and separately the UK GDPR, with each regime having the ability to fine up to the greater of €20 million/ £17 million or 4%
of global turnover. On October 12, 2023, the UK Extension to the DPF came into effect (as approved by the UK Government), as a data transfer
mechanism from the U.K. to U.S. entities self-certified under the DPF. As we continue to expand into other foreign countries and jurisdictions, we may be
subject to additional laws and regulations that may affect how we conduct business.
Although we work to comply with applicable laws, regulations and standards, our contractual obligations and other legal obligations, these requirements
are evolving and may be modified, interpreted and applied in an inconsistent manner among jurisdictions in which we operate. We are likely to be required
to expend significant capital and other resources to ensure ongoing compliance with applicable privacy and data security laws both inside and outside the
United States. Claims that we have violated individuals’ privacy rights or breached our contractual obligations regardless of merit and even if we are not
found liable, could be expensive and time-consuming to defend and could result in adverse publicity that could harm our business.
Claims that we or any collaborators fail to comply with applicable federal, state, or local, legal or regulatory requirements, could subject us to a range of
regulatory actions that could affect our or any collaborators’ ability to seek to commercialize our antibody candidates, if approved. Any threatened or actual
government enforcement action could also generate adverse publicity and require that we devote substantial resources that could otherwise be used in other
aspects of our business.
Risks Related to Commercialization of Our Antibody Candidates
We operate in highly competitive and rapidly changing industries, which may result in others discovering, developing or commercializing competing
products before or more successfully than we do.
The biopharmaceutical and pharmaceutical industries are highly competitive and subject to significant and rapid technological change. Our success is
highly dependent on our ability to discover, develop and obtain marketing approval for new and innovative products on a cost-effective basis and to market
them successfully. In doing so, we face and will continue to face intense competition from a variety of businesses, including large, fully integrated
pharmaceutical companies, specialty pharmaceutical companies and biopharmaceutical companies, academic institutions, government agencies and other
private and public research institutions in Europe, the United States and other jurisdictions. These organizations may have significantly greater resources
than we do and conduct similar research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and
marketing of products that compete with our antibody candidates.
With the proliferation of new drugs and therapies into oncology, we expect to face increasingly intense competition as new technologies become available.
If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Any antibody candidates that we successfully develop
and commercialize will compete with existing therapies and new therapies that may become available in the future. The highly competitive nature of and
rapid technological changes in the biotechnology and pharmaceutical industries could render our antibody candidates or our technology obsolete, less
competitive or uneconomical. Our competitors may, among other things:
•
•
have significantly greater financial, manufacturing, marketing, drug development, technical and human resources than we do;
develop and commercialize products that are safer, more effective, less expensive, more convenient or easier to administer, or have fewer or
less severe side effects;
73
•
•
•
•
obtain quicker regulatory approval;
establish superior proprietary positions covering our products and technologies;
implement more effective approaches to sales and marketing; or
form more advantageous strategic alliances.
Should any of these factors occur, our business, financial condition and results of operations could be materially adversely affected.
In addition, existing and future collaborators may decide to market and sell products that compete with the antibody candidates that we have agreed to
license to them. While we have agreements governing their committed activities, we have limited influence over their actual performance, and any
competition by our collaborators could also have a material adverse effect on our future business, financial condition and results of operations.
Smaller and other early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and
established companies. 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, retaining manufacturers to produce clinical trial materials, as well as in acquiring technologies
complementary to, or necessary for, our programs.
If we fail to obtain orphan drug designation for our antibody candidates, or obtain or maintain orphan drug exclusivity for our products, or lose or fail
to add to such designation for zenocutuzumab in the United States, our competitors may sell products to treat the same conditions and our revenue will
be reduced.
Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is intended to treat a rare disease or condition, defined as a patient
population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable
expectation that the cost of developing the drug will be recovered from sales in the United States. In the EU, 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 EU when the application is made, or (b) the product, without the benefits derived from orphan status,
would not generate sufficient return in the EU to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of
such condition authorized for marketing in the EU, or if such a method exists, the product will be of significant benefit to those affected by the condition.
Upon grant of a marketing authorization (MA), orphan medicinal products are entitled to a ten-year period of market exclusivity for the approved
therapeutic indication, which means that during this period, the regulatory authorities cannot accept another application for a MA or grant a MA or accept
an application to extend an existing MA for the same indication, in respect of a similar medicinal product. The application for orphan designation must be
submitted before the MA application (MAA). The applicant will receive a fee reduction for the MAA if the orphan designation has been granted, but not if
the designation is still pending at the time the MA is submitted. Orphan designation does not convey any advantage in, or shorten the duration of, the
regulatory review and approval process.
In the United States, orphan drug designation entitles a party to potential financial incentives such as opportunities for grant funding towards clinical trial
costs, tax advantages and user-fee waivers. In addition, if a product receives the first FDA approval for the disease or condition for which it has orphan
designation, the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other application to market the same drug for
the same disease or condition for a period of seven years, except in limited circumstances, such as a showing of clinical superiority over the product with
orphan exclusivity or where the manufacturer is unable to assure sufficient product quantity. In the EU, orphan designation entitles a party to potential
financial incentives such as reduction of fees or fee waivers and ten years of market exclusivity following drug or biological product approval. This period
may be reduced to six years if the orphan designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to
justify maintenance of market exclusivity or where the prevalence of the condition has increased above the threshold.
We have obtained orphan drug designation from the FDA for zenocutuzumab for the treatment of patients with pancreatic cancer and potentially may seek
that or a similar designation from the EMA for zenocutuzumab or additional orphan drug designations for zenocutuzumab, and we may seek such
designation from the FDA and foreign regulatory authorities for other clinical assets, where supported by data in the appropriate disease or condition that
meet the criteria for orphan status. Even though we obtained orphan designation in the United States for zenocutuzumab for treatment of patients with
pancreatic cancer and may obtain addition designations for zenocutuzumab, or orphan designations for other antibody candidates in the United States
and/or the EU, we may not be the first to obtain marketing approval for any particular orphan disease or condition due to the uncertainties associated with
developing pharmaceutical products. In addition, exclusive marketing rights in the United States may be limited if we seek approval
74
for a disease or condition broader than the orphan-designated disease or condition or may be lost if the FDA later determines that the request for
designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare
disease or condition. Further, even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from
competition because different drugs with different active moieties can be approved for the same condition. Even after an orphan drug is approved, the FDA
or foreign regulatory authorities can subsequently approve the same drug with the same active moiety for the same condition if the FDA or foreign
regulatory authorities concludes that the later drug is safer, more effective, or makes a major contribution to patient care. Orphan drug designation neither
shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. In
addition, while we intend to seek orphan drug designation, when appropriate, we may not receive such designation.
The successful commercialization of our antibody candidates will depend in part on the extent to which governmental authorities and health insurers
establish adequate coverage, reimbursement levels and pricing policies. Failure to obtain or maintain adequate coverage and reimbursement for our
antibody candidates, if approved, could limit our ability to market those products and decrease our ability to generate revenue.
The availability and adequacy of coverage and reimbursement by governmental healthcare programs such as Medicare and Medicaid, private health
insurers and other third-party payors are essential for most patients to be able to afford products such as our antibody candidates, assuming approval. Our
ability to achieve acceptable levels of coverage and reimbursement for products by governmental authorities, private health insurers and other organizations
will have an effect on our ability to successfully commercialize and attract additional collaborators to invest in the development of our antibody candidates.
Assuming we obtain coverage for a given product by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require
co-payments that patients find unacceptably high. We cannot be sure that coverage and reimbursement in the United States, the EU or elsewhere will be
available for any product that we may develop, and any reimbursement that may become available may be decreased or eliminated in the future. Third-
party payors increasingly are challenging prices charged for pharmaceutical products and services, and many third-party payors may refuse to provide
coverage and reimbursement for particular drugs when an equivalent generic drug or a less expensive therapy is available. It is possible that a third-party
payor may consider our antibody candidate and other therapies as substitutable and only offer to reimburse patients for the less expensive product. Even if
we show improved efficacy or improved convenience of administration with our antibody candidate, pricing of existing drugs may limit the amount we will
be able to charge for our antibody candidate. These payors may deny or revoke the reimbursement status of a given drug product or establish prices for new
or existing marketed products at levels that are too low to enable us to realize an appropriate return on our investment in product development. If
reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize our antibody candidates and may not
be able to obtain a satisfactory financial return on products that we may develop.
There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. In the United States, third-party payors,
including private and governmental payors, such as the Medicare and Medicaid programs, play an important role in determining the extent to which new
drugs and biologics will be covered. The Medicare and Medicaid programs increasingly are used as models for how private payors and other governmental
payors develop their coverage and reimbursement policies for drugs and biologics. Some third-party payors may require pre-approval of coverage for new
or innovative devices or drug therapies before they will reimburse health care providers who use such therapies. It is difficult to predict at this time what
third-party payors will decide with respect to the coverage and reimbursement for our antibody candidates, if approved.
Obtaining and maintaining reimbursement status is time-consuming and costly. No uniform policy for coverage and reimbursement for drug products exists
among third-party payors in the United States. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. As a
result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the
use of any future products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in
the first instance. Furthermore, rules and regulations regarding reimbursement change frequently, in some cases at short notice, and we believe that changes
in these rules and regulations are likely.
Outside the United States, international operations are generally subject to extensive governmental price controls and other market regulations, and we
believe the increasing emphasis on cost-containment initiatives in Europe, Canada, and other countries has and will continue to put pressure on the pricing
and usage of our antibody candidates, if approved. In many countries, the prices of medical products are subject to varying price control mechanisms as
part of national health systems. Other countries allow companies to fix their own prices for medical products, but monitor and control company profits.
Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our antibody candidates, if
approved. Accordingly, in markets outside the United States, the reimbursement for our products may be reduced compared with the United States and may
be insufficient to generate commercially reasonable revenue and profits.
75
Moreover, increasing efforts by governmental and third-party payors in the United States and abroad to cap or reduce healthcare costs may cause such
organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate
payment for our antibody candidates, if approved. We expect to experience pricing pressures in connection with the sale of any of our antibody candidates
that are approved 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 surgical procedures and other treatments, has become
very intense. As a result, increasingly high barriers are being erected to the entry of new products.
In addition, even if a pharmaceutical product obtains a marketing authorization in the EU, there can be no assurance that reimbursement for such product
will be secured on a timely basis or at all.
Our products may not gain market acceptance, in which case we may not be able to generate product revenues, which will materially adversely affect
our business, financial condition and results of operations.
Even if the FDA or any other regulatory authority approves the marketing of any antibody candidates that we develop on our own or with a collaborator,
physicians, healthcare providers, patients or the medical community may not accept or use them. If these products do not achieve an adequate level of
acceptance, we may not generate significant product revenues or any profits from operations. The degree of market acceptance of any of our antibody
candidates that are approved will depend on a variety of factors, including:
•
•
•
•
•
•
•
•
•
•
the timing of market introduction;
the number and clinical profile of competing products;
our ability to provide acceptable evidence of safety and efficacy;
the prevalence and severity of any side effects;
relative convenience and ease of administration;
cost-effectiveness;
patient diagnostics and screening infrastructure in each market;
marketing and distribution support;
availability of adequate coverage, reimbursement and adequate payment from health maintenance organizations and other insurers, both
public and private; and
other potential advantages over alternative treatment methods.
Failure of our antibody candidates, if approved, to gain market acceptance will have a material adverse impact on our ability to generate revenues to
provide a satisfactory, or any, return on our investments. Even if some products achieve market acceptance, the market may prove not to be large enough to
allow us to generate significant revenues.
We currently have limited marketing, sales or distribution infrastructure. If we are unable to adequately develop sales, marketing and distribution
capabilities on our own or through collaborations, we will not be successful in commercializing our antibody candidates.
While we have hired a Chief Commercial Officer and certain personnel to support market access and supply chain, we currently have only limited
marketing, and distribution capabilities, and no sales force, because all of our antibody candidates are still in clinical or pre-clinical development. If any of
our antibody candidates are approved, we intend either to establish a sales and marketing organization with technical expertise and supporting distribution
capabilities to commercialize our antibody candidates, or to outsource this function to a third party. Either of these options would be expensive and time
consuming. These costs may be incurred in advance of any approval of our antibody candidates. In addition, we may not be able to hire a sales force that is
sufficient in size or has adequate expertise in the medical markets that we intend to target. Any failure, delay or inadequacy in the development of our
internal sales, marketing and distribution capabilities would adversely impact the commercialization of any approved products.
To the extent that we enter into collaboration agreements with respect to marketing, sales or distribution, our product revenue may be lower than if we
directly marketed or sold any approved products. In addition, any revenue we receive will depend in whole or in part upon the efforts of these third-party
collaborators, which may not be successful and are generally not within our control. If we are
76
unable to enter into these arrangements on acceptable terms or at all, we may not be able to successfully commercialize any approved products. If we are
not successful in commercializing any approved products, either on our own or through collaborations with one or more third parties, our future product
revenue will suffer and we may incur significant additional losses.
We have never commercialized an antibody candidate before and may lack the necessary expertise, personnel and resources to successfully
commercialize our products on our own or together with suitable collaborators.
We have never commercialized an antibody candidate. While we have hired a Chief Commercial Officer and certain personnel to support market access
and supply chain, we currently have only limited marketing or distribution capabilities, and no sales force. To achieve commercial success for our antibody
candidates, if approved, which we may license to others, we will rely on the assistance and guidance of those collaborators. For antibody candidates for
which we retain commercialization rights, we will have to develop our own sales, marketing and supply organization or outsource these activities to a third
party. Outside consultants may be relied upon to provide advice on commercialization strategies, which may fail to deliver or provide effective guidance to
maximize any commercial opportunity, if any, that may arise from our antibody candidates.
Factors that may affect our ability to commercialize our antibody candidates on our own include obtaining effective advice from consultants on
commercialization strategy, recruiting and retaining adequate numbers of effective sales and marketing personnel, having adequate numbers of physicians
decide to prescribe our antibody candidates and other unforeseen costs associated with creating an independent sales and marketing organization.
Developing a sales and marketing organization will be expensive and time-consuming and could delay the launch of our antibody candidates, if approved.
We may not be able to build an effective sales and marketing organization. If we are unable to build our own distribution and marketing capabilities or to
find suitable partners for the commercialization of our antibody candidates, we may not generate revenues from them or be able to reach or sustain
profitability.
Our antibody candidates for which we intend to seek approval as biologic products may face competition sooner than anticipated.
The ACA includes a subtitle called the Biologics Price Competition and Innovation Act of 2009 (BPCIA) which created an abbreviated approval pathway
for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application for a
biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first approved by the FDA. In
addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first
approved. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a
full BLA for the competing product containing the sponsor’s own pre-clinical data and data from adequate and well-controlled clinical trials to demonstrate
the safety, purity and potency of their product.
We believe that any of our antibody candidates approved as a biological product under a BLA should qualify for the 12-year period of exclusivity.
However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise. Moreover, the extent to which a biosimilar, once
approved, will be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological products is
not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.
Jurisdictions in addition to the United States have established abbreviated pathways for regulatory approval of biological products that are biosimilar to
earlier approved reference products. For example, the EU has had an established regulatory pathway for biosimilars since 2006.
The increased likelihood of biosimilar competition has increased the risk of loss of innovators’ market exclusivity. Due to this risk, and uncertainties
regarding patent protection, if our antibody candidates are approved for marketing, it is not possible to predict the length of market exclusivity for any
particular product with certainty based solely on the expiration of the relevant patent(s) or the current forms of regulatory exclusivity. It is also not possible
to predict changes in United States regulatory law that might reduce biological product regulatory exclusivity. The loss of market exclusivity for a product
would likely materially and negatively affect revenues and we may not generate adequate or sufficient revenues from them or be able to reach or sustain
profitability.
Risks Related to Our Dependence on Third Parties
We rely, and expect to continue to rely, on third parties, including independent clinical investigators and CROs, to conduct our pre-clinical studies and
clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain
regulatory approval for or commercialize our antibody candidates and our business could be substantially harmed.
77
We have relied upon and plan to continue to rely upon third parties, including independent clinical investigators and third-party CROs, to conduct our pre-
clinical studies and clinical trials and to monitor and manage data for our ongoing pre-clinical and clinical programs. We rely on these parties for execution
of our pre-clinical studies and clinical trials, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of
our studies and trials is conducted in accordance with the applicable protocol, 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 antibody candidates in clinical development. Regulatory authorities enforce these GCPs through periodic inspections of trial
sponsors, principal investigators and trial sites. If we or any of our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical
trials may be deemed unreliable and the FDA, the EMA or comparable foreign regulatory authorities, who may require us to perform additional clinical
trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority
will determine that any of our clinical trials comply with GCP regulations. In addition, our clinical trials must be conducted with the antibody candidate
produced under cGMP or similar foreign regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would
delay the regulatory approval process.
Further, these investigators and CROs are not our employees and we will not be able to control, other than by contract, the amount of resources, including
time, which they devote to our antibody candidates and clinical trials. If independent investigators or CROs fail to devote sufficient resources to the
development of our antibody candidates, or if their performance is substandard, it may delay or compromise the prospects for approval and
commercialization of any antibody candidates that we develop. Moreover, as a result of the COVID-19 pandemic, certain of our third-party CROs have
been affected and in some instances have experienced cessation or mitigation of activity and may experience closures and labor shortages, negative impacts
concerning site oversight, data and medical monitoring, each of which alone or together may negatively affect our pre-clinical and clinical development
activities. In addition, the use of third-party service providers may require us to disclose our proprietary information to these parties, which could increase
the risk that this information will be misappropriated.
Our CROs have the right to terminate their agreements with us in the event of an uncured material breach. In addition, some of our CROs have an ability to
terminate their respective agreements with us if it can be reasonably demonstrated that the safety of the subjects participating in our clinical trials warrants
such termination, if we make a general assignment for the benefit of our creditors or if we are liquidated.
If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on
commercially reasonable terms. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be
replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory
requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or
successfully commercialize our antibody candidates. As a result, our results of operations and the commercial prospects for our antibody candidates would
be harmed, our costs could increase and our ability to generate revenues could be delayed.
Switching or adding additional CROs involves additional cost and requires management time and focus. In addition, there is a natural transition period
when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines.
Additionally, CROs may lack the capacity to absorb higher workloads or take on additional capacity to support our needs. Though we carefully manage our
relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or
challenges will not have a material adverse impact on our business, financial condition and prospects.
The collaboration and license agreement, or the Collaboration Agreement, with Incyte Corporation (Incyte) is important to our business. If suitable
monospecific or bispecific antibody candidates are not identified for further development and commercialization activities under the Collaboration
Agreement, or if we or Incyte fail to adequately perform under the Collaboration Agreement, or if we or Incyte terminate the Collaboration Agreement,
the development and commercialization of our antibody candidates would be delayed or terminated and our business would be adversely affected.
The Collaboration Agreement may be terminated:
•
•
in its entirety or on a program-by-program basis by Incyte for convenience;
in its entirety or on a program-by-program basis by either party due to a material breach of the Collaboration Agreement, or any one or
more programs under the Collaboration Agreement, as applicable; and
78
•
on a program-by-program basis (but not in its entirety), by either party if the other party challenges the terminating party’s patents for such
program, and such challenge is not withdrawn within 30 days.
If the Collaboration Agreement is terminated with respect to one or more programs, all rights in the terminated programs revert to us, subject to payment to
Incyte of a reverse royalty of up to 4% on sales of future products, depending on the stage of development as of the date of termination, if we elect to
pursue development and commercialization of monospecific or bispecific antibody candidates arising from the terminated programs.
Termination of the Collaboration Agreement could cause significant delays in our antibody candidate development and commercialization efforts, which
could prevent us from commercializing our antibody candidates without first expanding our internal capabilities or entering into another agreement with a
third party. Any suitable alternative collaboration or license agreement would take considerable time to negotiate and could also be on less favorable terms
to us. In addition, under the Collaboration Agreement, Incyte agreed to conduct certain clinical development activities. If the Collaboration Agreement
were to be terminated, and whether or not we identify another suitable collaborator, we may need to seek additional financing to support the research and
development of any terminated antibody candidates so that we may continue development activities, or we may be forced to discontinue development of
terminated antibody candidates, each of which could have a material adverse effect on our business.
Under the Collaboration Agreement, we are dependent upon Incyte to successfully develop and commercialize any antibody candidates that are identified
for further development under the Collaboration Agreement. With the exception of those programs where we retain certain co-development rights, we have
limited ability to influence or control Incyte’s development and commercialization activities or the resources it allocates to development of product
candidates identified under the Collaboration Agreement. Our interests and Incyte’s interests may differ or conflict from time to time, or we may disagree
with Incyte’s level of effort or resource allocation. Incyte may internally prioritize programs under development within the collaboration differently than we
would, or it may not allocate sufficient resources to effectively or optimally develop or commercialize antibody candidates arising from such programs. If
these events were to occur, our ability to receive revenue from the commercialization of products arising from such programs would be reduced, and our
business would be adversely affected.
The collaboration and license agreement, or the Lilly Collaboration Agreement, with Eli Lilly is important to our business. If suitable monospecific or
bispecific antibody candidates are not identified for further development and commercialization activities under the Lilly Collaboration Agreement, or
if we or Eli Lilly fail to adequately perform under the Lilly Collaboration Agreement, or if we or Eli Lilly terminate the Lilly Collaboration Agreement,
the development and commercialization of our antibody candidates would be delayed or terminated and our business would be adversely affected.
The Lilly Collaboration Agreement may be terminated:
•
•
•
in its entirety or on a program-by-program basis by Eli Lilly for convenience;
on a product-by-product basis (but not in its entirety), by Merus if Lilly challenges the Merus patents for such product and
in its entirety or on a program-by-program basis by either party due to a material breach of the Lilly Collaboration Agreement, or any one or
more programs under the Lilly Collaboration Agreement, as applicable.
If the Lilly Collaboration Agreement is terminated with respect to one or more programs, depending on the stage of development, certain rights in the
terminated programs revert to us.
Termination of the Lilly Collaboration Agreement could cause significant delays in our antibody candidate development and commercialization efforts,
which could prevent us from commercializing our antibody candidates without first expanding our internal capabilities or entering into another agreement
with a third party. Any suitable alternative collaboration or license agreement would take considerable time to negotiate and could also be on less favorable
terms to us. In addition, under the Lilly Collaboration Agreement, Eli Lilly agreed to conduct certain pre-clinical and clinical development activities. If the
Lilly Collaboration Agreement were to be terminated, and whether or not we identify another suitable collaborator, we may need to seek additional
financing to support the research and development of any terminated antibody candidates so that we may continue development activities, or we may be
forced to discontinue development of terminated antibody candidates, each of which could have a material adverse effect on our business.
Under the Lilly Collaboration Agreement, we are dependent upon Eli Lilly to successfully develop and commercialize any antibody candidates that are
identified for further development under the Lilly Collaboration Agreement. We have limited ability to influence or control Eli Lilly’s development and
commercialization activities or the resources it allocates to development of product candidates
79
identified under the Lilly Collaboration Agreement. Our interests and Eli Lilly’s interests may differ or conflict from time to time, or we may disagree with
Eli Lilly’s level of effort or resource allocation. Eli Lilly may internally prioritize programs under development within the collaboration differently than we
would, or it may not allocate sufficient resources to effectively or optimally develop or commercialize antibody candidates arising from such programs. If
these events were to occur, our ability to receive revenue from the commercialization of products arising from such programs would be reduced, and our
business would be adversely affected.
The collaboration and license agreement with Betta Pharma, and the research and license agreements with Ono are important to our business. If our
Biclonics® antibodies licensed in these collaboration and license agreements fail to advance or experience unacceptable safety or efficacy results if
clinically developed, this could adversely impact the reputation of our platform and our ability to engage in future collaborations.
If our collaboration and license agreement with Betta Pharma or our research and license agreements with Ono are terminated with respect to one or more
programs, or the pre-clinical assets associated with the Ono license agreements fail to advance into the clinic, or experience negative results with respect to
safety, efficacy, manufacturability, or other features of research and development, this could adversely affect the reputation of our Biclonics® technology
platform and our ability to engage in future collaborations or licensing agreements. While we have certain contractual provisions in place in our
collaboration and license agreement with Betta Pharma that permit us to supervise its development efforts for MCLA-129, for which it has development
and product rights in China, we cannot guarantee that this clinical antibody candidate will be developed in China in accordance with our standards as
applied to our wholly owned programs or in a manner suitable for ex-China development or in a manner that does not detract from our development of
MCLA-129 outside of China. Ono is currently clinically developing at least two antibody programs generated by us under a license agreement with Merus
through use of our proprietary Biclonics® platform. To the extent these assets do not successfully advance through clinical development, this may impair
our ability to leverage our platform in future license agreements to further expand the use of our platform and generate future revenue. Should the Betta
Pharma collaboration or Ono license agreements fail or be terminated, any suitable alternative collaboration or license agreement would take considerable
time to negotiate, if at all, and could also be on less favorable terms to us. If these agreements were to be terminated, and whether or not we identify a
suitable alternative collaborator, we may need to seek additional financing to support the research and development of any terminated antibody candidates
so that we may continue development activities, or we may be forced to discontinue development of terminated antibody candidates, each of which could,
depending on the stage of development and investment, have a material adverse effect on our business.
If we fail to enter into new strategic relationships our business, financial condition, commercialization prospects and results of operations may be
materially adversely affected.
Our product development programs and the potential commercialization of our antibody candidates will require substantial additional cash to fund
expenses. Therefore, for some of our antibody candidates and with respect to our Triclonics® technology platform, we may decide to enter into new
collaborations with pharmaceutical or biotechnology companies for the development and potential commercialization of those bispecific and trispecific
antibody candidates. For instance, we have license and collaboration agreements with Ono, Incyte, Eli Lilly and Betta Pharma, under which we have
licensed certain development and commercialization rights of certain of our monospecific or bispecific antibody candidates.
We face significant competition in seeking appropriate collaborators. Collaborations are complex and time-consuming to negotiate and document. We may
also be restricted under existing and future collaboration agreements from entering into agreements on certain terms with other potential collaborators. We
may not be able to negotiate collaborations on acceptable terms, or at all. If that were to occur, we may have to curtail the development of a particular
bispecific or trispecific antibody candidate, reduce or delay its development program or one or more of our other development programs, delay its potential
commercialization or reduce the scope of our sales or marketing activities, or increase our expenditures and undertake development or commercialization
activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to
obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we will not be able to bring our
antibody candidates to market, further research and develop new trispecific antibody candidates, enhance our Biclonics® and Triclonics® technology
platforms and generate product revenue. If we do enter into a new collaboration agreement, we could be subject to the following risks, each of which may
materially harm our business, commercialization prospects and financial condition:
•
•
we may not be able to control the amount and timing of resources that the collaborator devotes to the product development program;
the collaborator may experience financial difficulties;
80
•
•
•
•
we may be required to relinquish important rights such as marketing, distribution and intellectual property rights;
a collaborator may experience technical, clinical, intellectual property, manufacturing or other setbacks in the research or development of a
product program arising from our collaboration adversely affecting the financial return of our collaboration or the reputation of our
technology platform;
a collaborator could move forward with a competing product developed either independently or in collaboration with third parties, including
our competitors; or
business combinations or significant changes in a collaborator’s business strategy may adversely affect our willingness to complete our
obligations under any arrangement.
We currently rely on third-party suppliers and other third parties for production of our antibody candidates and our dependence on these third parties
may impair the advancement of our research and development programs and the development of our antibody candidates. Moreover, we intend to rely
on third parties to produce commercial supplies of any approved antibody candidate and our commercialization of any of our antibody candidates
could be stopped, delayed or made less profitable if those third parties fail to obtain approval of the FDA or comparable foreign regulatory authorities
following inspection of their facilities and procedures to manufacture our antibody candidates and products, fail to provide us with sufficient quantities
of antibody product or fail to do so at acceptable timing, quality levels or prices or fail to otherwise complete their duties in compliance with their
obligations to us or other parties.
We rely on and expect to continue to rely on third-party contract manufacturing organizations (CMOs) for the supply of cGMP-grade clinical trial materials
and commercial quantities of our antibody candidates and products, if approved. Reliance on third-party providers may expose us to more risk than if we
were to manufacture antibody candidates ourselves. The facilities used by our CMOs to manufacture our antibody candidates must be approved by the
FDA foreign regulatory authorities pursuant to inspections that will be conducted after we submit our BLA to the FDA, or similar applications to foreign
regulatory authorities. We have limited control over the manufacturing process of, and beyond contractual terms, we are completely dependent on our
CMOs for compliance with cGMP or similar foreign requirements for the manufacture of our antibody candidates. If our CMOs cannot successfully
manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or comparable foreign regulatory authorities, or
are unable to do so in a timely manner, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities or may result in
delay of our ability to obtain marketing authorization, if any, of our antibody candidates. In addition, we have limited control over the ability of our CMOs
to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve
these facilities for the manufacture of our antibody candidates or if it withdraws any such approval in the future, we may need to find alternative
manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our antibody candidates, if
approved. In addition, any failure to achieve and maintain compliance with these laws, regulations and standards could subject us to the risk that we may
have to suspend the manufacturing of our antibody candidates or that obtained approvals could be revoked, which would adversely affect our business and
reputation. Furthermore, third-party providers may breach existing agreements they have with us because of factors beyond our control. They may also
terminate or refuse to renew their agreement because of their own financial difficulties or business priorities, at a time that is costly or otherwise
inconvenient for us. If we were unable to find an adequate replacement or another acceptable solution in time, our clinical trials could be delayed or our
commercial activities could be harmed. In addition, the fact that we are dependent on our collaborators, our CMOs and other third parties for the
manufacture, filling, storage and distribution of our antibody candidates means that we are subject to the risk that the products may have manufacturing
defects that we have limited ability to prevent or control. The sale of products containing such defects could adversely affect our business, financial
condition and results of operations.
We rely on our CMOs to purchase from third-party suppliers the materials necessary to produce our antibody candidates for our clinical trials, and will rely
on our existing and future collaborators to purchase from third-party suppliers the materials necessary to develop and produce our antibody candidates for
future clinical trials and, upon approval, our products for commercialization. There are a limited number of suppliers for raw materials that we use to
manufacture our antibody candidates and there may be a need to assess alternate suppliers to prevent a possible disruption of the manufacture of the
materials necessary to produce our antibody candidates for our clinical trials, and if approved, ultimately for commercial sale. Apart from contractual
measures, we do not have any control over the process or timing of the acquisition of these raw materials by our manufacturers or manufacturers paid by
our collaborators. Moreover, we currently do not have any agreements for the commercial production of these raw materials. Although we generally do not
begin a clinical trial unless we believe we have a sufficient supply of an antibody candidate to complete the clinical trial or have secured resupply capacity,
any significant delay in the supply of an antibody candidate, or the raw material components
81
thereof, for a planned or an ongoing clinical trial due to the need to replace a third-party manufacturer could considerably delay completion of our clinical
trials, product testing and potential regulatory approval of our antibody candidates.
In addition, the manufacturing of our novel antibody candidates is expensive and time-consuming, and generally requires more complex processes than
those associated with small-molecule drugs. If we are successful in obtaining regulatory approval for any of our antibody candidates, including
zenocutuzumab, we might have limited quantities of such antibody candidates available to us in connection with a potential commercial launch, and these
supplies may be further limited by our ongoing clinical development activities. If our manufacturers, collaborators or we are unable to purchase or produce
sufficient quantities of raw materials or of our antibody candidates after regulatory approval has been obtained for our antibody candidates, the commercial
launch of our antibody candidates could be delayed or there could be a shortage in supply, which in either case, would impair our ability to generate
revenues from the sale of our antibody candidates.
We rely on our manufacturers and other subcontractors to comply with and respect the proprietary rights of others in conducting their contractual
obligations for us. If our manufacturers or other subcontractors fail to acquire the proper licenses or otherwise infringe third party proprietary rights in the
course of completing their contractual obligations to us, we may have to find alternative manufacturers or defend against claims of infringement, either of
which would significantly impact our ability to develop, obtain regulatory approval for or market our antibody candidates, if approved.
Risks Related to Intellectual Property and Information Technology
We rely on patents and other intellectual property rights to protect our technology, including antibody candidates and our Biclonics® technology
platform and Triclonics® technology platform, the enforcement, defense and maintenance of which may be challenging and costly. Failure to enforce
or protect these rights adequately could harm our ability to compete and impair our business.
Our commercial success depends in part on obtaining and maintaining patents and other forms of intellectual property rights for our Biclonics® technology
platform, Triclonics® technology platform, our common light chain transgenic technology, our dimerization technology, our heavy chain variable regions
and binding domains that bind particular antigens, our monospecific antibodies, bispecific antibody, trispecific antibody and antibody pre-clinical and
clinical candidates, products, their format and methods and host cells used to produce, screen, manufacture and purify those pre-clinical antibody and
antibody clinical candidates, the methods for treating patients using those candidates, among other aspects of our technology or on licensing-in such rights.
Failure to protect or to obtain, maintain or extend adequate patent and other intellectual property rights could materially adversely affect our ability to
develop and market our platform technologies, and antibody candidates.
The patent prosecution process is expensive and time-consuming, and we and our current or future licensors, licensees or collaborators may not be able to
prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we or our
licensors, licensees or collaborators will 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. Further, the issuance, scope, validity, enforceability and commercial value of our and our
current or future licensors’, licensees’ or collaborators’ patent rights are highly uncertain. Our and our licensors’ pending and future patent applications
may not result in patents being issued which protect our technology or products, in whole or in part, or which effectively prevent others from
commercializing competitive technologies and products. The patent examination process may require us or our licensors, licensees or collaborators to
narrow the scope of the claims of our or our licensors’, licensees’ or collaborators’ pending and future patent applications, which may limit the scope of
patent protection that may be obtained. We cannot assure you that all of the potentially relevant prior art relating to our patents and patent applications has
been found. If such prior art exists, it can invalidate a patent or prevent a patent from issuing from a pending patent application. Even if patents do
successfully issue, or have issued and even if such patents cover our Biclonics® technology platform, Triclonics® technology platform, our common light
chain transgenic technology, our dimerization technology our heavy chain variable regions and binding domains that bind particular antigens, our
monospecific antibodies, bispecific antibody, trispecific antibody and antibody pre-clinical and clinical candidates, products, their format and methods and
host cells used to produce, screen, manufacture and purify those pre-clinical antibody and antibody clinical candidates, the methods for treating patients
using those candidates, and other technologies, third parties may initiate opposition, interference, re-examination, post-grant review, inter partes review,
nullification or derivation action in court or before patent offices, or similar proceedings challenging the validity, enforceability or scope of such patents,
which may result in the patent claims being narrowed or invalidated. Our and our licensors’, licensees’ or collaborators’ patent applications cannot be
enforced against third parties practicing the technology claimed in such applications unless and until a patent issues from such applications, and then only
to the extent the issued claims cover the technology in the relevant jurisdiction.
82
Because patent applications are confidential for a period of time after filing, and some remain so until issued, we cannot be certain that we or our licensors
were the first to file any patent application related to our technology, including our antibody candidates. Furthermore, if third parties have filed such patent
applications on or before March 15, 2013, an interference proceeding can be initiated by such third parties to determine who was the first to invent any of
the subject matter covered by the patent claims of our applications. If third parties have filed such applications after March 15, 2013, a derivation
proceeding can be initiated by such third parties to determine whether our invention was derived from theirs.
Issued patents covering one or more of our products or the Biclonics® technology or Triclonics® technology platforms could be found invalid or
unenforceable if challenged in court.
To protect our competitive position, we may from time to time need to resort to litigation to enforce or defend any patents or other intellectual property
rights owned by or licensed to us, or to determine or challenge the scope or validity of patents or other intellectual property rights of third parties. As
enforcement of intellectual property rights is difficult, unpredictable and expensive, we may fail in enforcing our rights—in which case our competitors
may be permitted to use our technology without being enjoined, required to pay us any license fees, or compensate us for lost profits or reasonable royalty.
In addition, litigation involving our patents carries the risk that one or more of our patents will be held invalid (in whole or in part, on a claim-by-claim
basis) or held unenforceable. Such an adverse court ruling could allow third parties to commercialize technology covered by our patents we seek to enforce,
such as those covering our antibody candidates or methods, our Biclonics® technology and Triclonics® technology platforms, our common light chain
transgenic technology, or our dimerization technology, among other technologies, and then compete directly with us, without payment to us.
If we were to initiate legal proceedings against a third party to enforce a patent covering our technology, one of our products or methods, the defendant
could counterclaim that our patent is invalid and/or unenforceable. In patent litigation in the United States or in certain jurisdictions in Europe, defendant
counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of
several statutory requirements for patentability, for example, lack of utility, novelty, obviousness, non-enablement or lack of written description or as
constituting unpatentable subject matter. Grounds for an unenforceability assertion could be an allegation that someone substantively involved in
prosecution of the patent withheld but-for material information from the U.S. Patent and Trademark Office (USPTO) or engaged in affirmatively egregious
misconduct, during prosecution, with a specific intent to deceive the USPTO. The outcome following legal assertions of invalidity and unenforceability
during patent litigation is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of
which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or
unenforceability, we could lose at least part, and perhaps all, of the patent protection on one or more of our technologies, products, methods or certain
aspects of our Biclonics® technology and Triclonics® technology platforms. Such a loss of patent protection could have a material adverse impact on our
business. Patents and other intellectual property rights also will not protect our technology if competitors design around our protected technology without
infringing our patents or other intellectual property rights.
Intellectual property rights of third parties could adversely affect our ability to commercialize our antibody candidates, such that we could be required
to litigate or obtain licenses from third parties in order to develop or market our antibody candidates. Such litigation or licenses could be costly or not
available on commercially reasonable terms or at all.
Our competitive position may suffer if patents issued to third parties or other third-party intellectual property rights cover our technology platforms,
methods or candidates or elements thereof, our manufacture or uses relevant to our development, or other attributes of our antibody candidates or our
Biclonics® technology platform or Triclonics® technology platform. In such cases, we may not be in a position to develop or commercialize products or
antibody candidates unless we successfully pursue litigation, opposition, inter partes, or related post-grant proceedings to nullify or invalidate the third-
party intellectual property right concerned, or enter into a license agreement with the intellectual property right holder, if available on commercially
reasonable terms. In addition, we are aware of issued patents and/or pending patent applications held by third parties that could be alleged as covering some
of our antibody candidates, irrespective of the merits. We believe that if such patents or patent applications (if issued as currently pending) were asserted
against us, we would have counterclaims and defenses against such claims, including non-infringement, the affirmative defense of safe harbor designed to
protect activity undertaken to obtain federal regulatory approval of a drug, including under 35 U.S.C. § 271(e) and similar foreign exceptions to
infringement, and defenses concerning patent invalidity and/or unenforceability. However, if such counterclaims and defenses were not successful and such
patents were successfully asserted against us such that they are found to be valid and enforceable, and infringed, unless we obtain a license to such patents,
which may not be available on commercially reasonable terms or at all, we could be prevented from continuing to develop or commercialize our
technology. We could also be required to pay substantial damages.
83
It is also possible that in our evaluation of third party intellectual property, we failed to identify relevant patents or applications. For example, U.S.
applications filed before November 29, 2000 and certain U.S. applications filed after that date that will not be filed outside the United States remain
confidential until patents issue. Patent applications in the United States and elsewhere are published approximately 18 months after the earliest filing for
which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our
products or platform technologies could have been filed by others without our knowledge. Furthermore, we operate in a highly competitive field, and given
our limited resources, it is unreasonable to monitor all patent applications purporting to claim broad coverage in the areas in which we are active.
Additionally, pending patent applications which have been published can, subject to certain limitations, be later amended in a manner that could cover our
platform technologies, our methods, antibody candidates or the use of our bispecific and trispecific antibody candidates.
Third party intellectual property right holders, including our competitors, may actively bring infringement claims against us. The granting of orphan drug
status in respect of any of our antibody candidates does not guarantee our freedom to operate and is separate from our risk of possible infringement of third
parties’ intellectual property rights. We may not be able to successfully settle or otherwise resolve such potential infringement claims. If we are unable to
successfully settle future claims on terms acceptable to us, we may be required to engage or continue costly, unpredictable and time-consuming litigation
and may be prevented from or experience substantial delays in marketing any approved products.
If we fail in any such dispute, in addition to being forced to potentially pay damages, we or our licensees may be temporarily or permanently prohibited
from commercializing any of our antibody candidates that are held to be infringing or be forced to redesign antibody candidates so that we no longer
infringe the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial
financial and management resources that we would otherwise be able to devote to our business.
In addition, if the breadth or strength of protection provided by our or our present or future licensors’, collaborators’ or partners’ patents and patent
applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future antibody
candidates. Furthermore, 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.
Our ability to compete may be adversely affected if we are unsuccessful in defending against any claims by competitors or others that we are infringing
upon their intellectual property rights.
The various markets in which we plan to operate are subject to frequent and extensive litigation regarding patents and other intellectual property rights. In
addition, many companies in intellectual property-dependent industries, including those producing therapeutic candidates or products to treat and
potentially cure cancer, have employed intellectual property litigation as a means to gain an advantage over their competitors. As a result, we may be
required to defend against claims of intellectual property infringement that may be asserted by our competitors against us and, if the outcome of any such
litigation is adverse to us, it may affect our ability to compete effectively.
Our involvement in litigation, and in any interferences, opposition, pre and post-grant administrative proceedings or other intellectual property proceedings
inside and outside of the United States may divert management from focusing on business operations, could cause us to spend significant amounts of
money and may have no guarantee of success. Any potential intellectual property litigation successfully adjudicated against us could also force us to do one
or more of the following:
•
•
•
•
stop selling, incorporating, manufacturing or using our products, if approved, in the United States and/or other jurisdictions that are covered
by the subject intellectual property;
obtain from a third party asserting its intellectual property rights, a license to sell or use the relevant technology, which license may not be
available on reasonable terms, or at all, or may be non-exclusive thereby giving our competitors access to the same technologies licensed to
us;
redesign those technologies, products or processes that use any allegedly infringing or misappropriated technology, which may result in
significant cost or delay to us, or which redesign could be technically infeasible; or
pay damages, including the possibility of treble damages in a patent case if a court finds us to have willfully infringed certain intellectual
property rights.
84
We are aware that significant number of patents and patent applications may exist relating to aspects of therapeutic antibody technologies filed by, and
issued to, third parties.
We cannot assure you that we will ultimately prevail if any of this third-party intellectual property is asserted against us.
Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.
Where we are asserting our intellectual property against third parties, or defending against an allegation of infringement, even if resolved in our favor,
litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our technical and
management 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, this could have a substantial adverse effect
on the price of our common shares. Such litigation or proceedings and the legal costs associated with them, could substantially increase our operating
losses and reduce our resources available for development activities. We may not have sufficient financial or other resources to adequately conduct such
litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because
of their substantially greater financial resources. 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.
We may not be successful in obtaining or maintaining necessary rights to our antibody candidates through acquisitions and in-licenses.
We currently have rights and own our intellectual property, including issued patents and pending patent applications, relating to and covering our
Biclonics® technology and Triclonics® technology platforms, our common light chain transgenic technology, our dimerization technology, our heavy
chain variable regions and binding domains that bind particular antigens, our monospecific antibodies, bispecific antibody, trispecific antibody and pre-
clinical antibody and antibody clinical candidates, products, their format and methods and host cells used to produce, screen, manufacture and purify those
pre-clinical antibody and antibody clinical candidates, the methods for treating patients using those candidates, among other aspects of our technology.
Because our programs may require the use of proprietary rights held by third parties, the growth of our business may depend in part on our ability to
acquire, in-license, maintain or use these proprietary rights. We may be unable to acquire or in-license any compositions, methods of use, processes, or
other third-party intellectual property rights from third parties that we may identify as necessary for our antibody candidates. The licensing and acquisition
of third-party intellectual property rights is a competitive area, and a number of more established companies are also pursuing strategies to license or
acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due
to their size, cash resources, and greater clinical development and commercialization capabilities.
In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire
third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment. If we are unable to successfully obtain
a license to third-party intellectual property rights necessary for the development of an antibody candidate or program, we may have to abandon
development of that antibody candidate or program and our business and financial condition could suffer.
If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our
business may be adversely affected.
We currently have trademark and service mark rights relating to and covering our Biclonics® technology and Triclonics® technology platforms,
zenocutuzumab and other aspects of our company, its services and activities used in commerce. Our registered or unregistered trademarks, trade names or
service marks may be challenged including during prosecution or through opposition proceedings, infringed, circumvented or declared generic or
determined to be infringing on other marks. We may not be able to protect our rights to these trademarks, trade names, and service marks, which we need to
build name recognition by potential collaborators, partners or customers in our markets of interest. Over the long term, if we are unable to establish name
recognition based on our trademarks, trade names and service marks then we may not be able to compete effectively and our business may be adversely
affected. If other entities use trademarks, trade names or service marks similar to ours in different jurisdictions, or have senior rights to ours, or prevail in
any opposition proceedings, it could interfere with our use of our current trademarks, trade names or service marks throughout the world.
If we do not obtain protection under the Hatch-Waxman Amendments and similar non-U.S. legislation for extending the term of patents covering each
of our antibody candidates, our business may be materially harmed.
85
Patents typically 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, not including potential patent term extensions or adjustments that may be available in the U.S., and under
comparable laws applicable outside the U.S., where certain conditions are met. Various extensions may be available, but the life of a patent, and the
protection it affords, is limited. Even if patents covering our antibody candidates are obtained, once the patent life has expired for a candidate, we may be
open to competition from competitive medications, including biosimilar or generic medications. Given the amount of time required for the development,
testing and regulatory review of new antibody candidates, patents protecting such candidates might expire before or shortly after such candidates are
commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing
products similar or identical to ours, causing our revenue from applicable products to be reduced, possibly materially, and potentially harming our ability to
recover our investment in such product or obtain a reasonable return on that investment.
Depending upon the timing, duration and conditions of FDA marketing approval of our antibody candidates, one or more of our U.S. patents may be
eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman
Amendments, and similar legislation in the EU. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a patent covering
an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. However, we may
not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy
applicable requirements. Moreover, the length of the extension could be less than we request. If we are unable to obtain patent term extension or the term of
any such extension is less than we request, the period during which we can enforce our patent rights for that product will be shortened and our competitors
may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced, possibly materially.
We enjoy only limited geographical protection with respect to certain patents and may face difficulties in certain jurisdictions, which may diminish the
value of intellectual property rights in those jurisdictions.
We generally file our first patent application (i.e., priority filing) in the Netherlands. International applications under the Patent Cooperation Treaty (PCT)
are usually filed within 12 months after the priority filing, where we pursue patent applications in the U.S., across the E.U., and other PCT participating
jurisdictions, as based on the PCT filing, national and regional patent applications may be filed in additional jurisdictions where we believe our antibody
candidates may be marketed or manufactured or our platform technologies may be utilized. We have so far not filed for patent protection in all national and
regional jurisdictions where such protection may be available. In addition, we may decide to abandon national and regional patent applications before grant.
Finally, the grant proceeding of each national/regional patent is an independent proceeding which may lead to situations in which applications might in
some jurisdictions be refused by the relevant patent offices, while granted by others. It is also quite common that depending on the country, the scope of
patent protection may vary for the same antibody candidate and/or technology.
Competitors may use our and our existing or future licensors’, collaborators’ or partners’ technologies in jurisdictions where we have not obtained patent
protection to develop their own products and, further, may export otherwise infringing products to territories where we and our existing or future licensors,
collaborators or partners have patent protection, but enforcement is not as strong as that in the United States. These products may compete with our
antibody candidates or our platform technologies, and our and our existing or future licensors’, collaborators’ or partners’ patents or other intellectual
property rights may not be effective or sufficient to prevent them from competing.
The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the United States and the EU, and many
companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. If we or our existing or future licensors,
collaborators or partners encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights
important for our business in such jurisdictions, the value of these rights may be diminished and we may face additional competition from others in those
jurisdictions.
Some countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, some countries
limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies,
which could materially diminish the value of such patent. If we or any of our existing or future licensors, collaborators or partners is forced to grant a
license to third parties with respect to any patents relevant to our business, our competitive position may be impaired and our business and results of
operations may be adversely affected.
Intellectual property rights do not necessarily address all potential threats to our competitive advantage.
86
The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not
adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:
•
•
•
•
•
•
•
•
•
•
others may be able to make compounds that are the same as or similar to our antibody candidates but that are not covered by the claims of
the patents that we own or have exclusively licensed;
the patents of third parties may have an adverse effect on our business;
we or our licensors or any future strategic partners might not have been the first to conceive or reduce to practice the inventions covered by
the issued patent or pending patent application that we own or have exclusively licensed;
we or our licensors or any future strategic partners might not have been the first to file patent applications covering certain of our
inventions;
others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual
property rights;
it is possible that our pending patent applications will not lead to issued patents;
issued patents that we own or have exclusively licensed may not provide us with any competitive advantage, or may be held invalid or
unenforceable, as a result of legal challenges by our competitors;
our competitors might conduct research and development activities in countries where we do not have patent rights and then use the
information learned from such activities to develop competitive products for sale in our major commercial markets;
third parties performing manufacturing or testing for us using our antibody candidates or technologies could use the intellectual property of
others without obtaining a proper license; and
we may not develop additional technologies that are patentable.
Changes in patent laws or patent jurisprudence could diminish the value of patents in general, thereby impairing our ability to protect our antibody
candidates and technology platforms.
As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and
enforcing patents in the biopharmaceutical industry involve both technological complexity and legal complexity. Therefore, obtaining and enforcing
biopharmaceutical patents is costly, time-consuming and inherently uncertain.
In September 2011, the America Invents Act (AIA) was enacted in the United States, resulting in significant changes to the U.S. patent system. An
important change introduced by the AIA was a transition to a “first-to-file” system for deciding which party should be granted a patent when two or more
patent applications are filed by different parties claiming the same invention, which went into effect on March 16, 2013. Therefore, a third party that now
files a patent application in the USPTO before we do could be awarded a patent covering an invention of ours even if we created the invention before it was
created by the third party. While we are cognizant of the time from invention to filing of a patent application, circumstances could prevent us from
promptly filing patent applications for our inventions.
Among some of the other changes introduced by the AIA were changes that limit where a patentee may file a patent infringement suit and providing
opportunities for third parties to challenge any issued patent in the USPTO. This applies to all of our U.S. patents, even those issued before March 16,
2013. Because of a lower burden of proof in USPTO proceedings compared to the burden of proof in U.S. federal courts necessary to invalidate a patent
claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same
evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO
procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action.
The AIA and its continued implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications, and the patent
applications of our existing and future collaborators or licensors and the enforcement or defense of our issued patents.
Depending on decisions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in
unpredictable ways that could weaken our ability to obtain new patents or to enforce our existing patents and patents that we
87
might obtain in the future. Similarly, there is complexity and uncertainty related to European patent laws. For example, the European Patent Convention
was amended in April 2010 to limit the time permitted for filing divisional applications. In addition, the EPO patent system is relatively stringent in the
type of amendments that are allowed during prosecution. These limitations and requirements could adversely affect our ability to obtain new patents in the
future that may be important for our business.
Confidentiality agreements with employees, contractors, agents, consultants, collaborators and others may not adequately prevent disclosure of trade
secrets and protect other proprietary information.
We consider proprietary trade secrets and/or confidential know-how and unpatented know-how to be important to our business. We may rely on trade
secrets and/or confidential know-how to protect our technology, especially where patent protection is believed to be of limited value. However, trade
secrets and/or confidential know-how are difficult to maintain as confidential.
To protect this type of information against disclosure or appropriation by competitors, our policy is to require our employees, consultants, contractors,
collaborators and advisors to enter into confidentiality agreements with us, our practice is to provide regular trainings on the importance of maintaining
confidentiality, to promulgate a business code of conduct requiring confidentiality, and prohibit the use of non-sanctioned devices with company
confidential information. However, current or former employees, consultants, contractors, collaborators and advisers may unintentionally or willfully
disclose our confidential information to competitors, and confidentiality agreements and other precautions taken may not provide an adequate remedy in
the event of unauthorized disclosure of confidential information or we may be unaware of such disclosure to enforce our confidentiality agreements and
other remedies. Enforcing a claim that a third party obtained illegally and is using trade secrets and/or confidential know-how is expensive, time consuming
and unpredictable. The enforceability of confidentiality agreements and theft of trade secret claims may vary from jurisdiction to jurisdiction. Furthermore,
if a competitor lawfully obtained or independently developed any of our trade secrets, we would have no right to prevent such competitor from using that
technology or information to compete with us, which could harm our competitive position. Additionally, if the steps taken to maintain our trade secrets are
deemed inadequate, we may have insufficient recourse against third parties for misappropriating the trade secret.
Failure to obtain or maintain trade secrets and/or confidential know-how trade protection could adversely affect our competitive position. Moreover, our
competitors may independently develop substantially equivalent proprietary information and may even apply for patent protection in respect of the same. If
successful in obtaining such patent protection, our competitors could limit our use of our trade secrets and/or confidential know-how.
Under certain circumstances and to guarantee our freedom to operate, we may also decide to publish some know-how to prevent others from obtaining
patent rights covering such know-how.
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 employees, including our senior management, were previously employed at universities or at pharmaceutical or biotechnology companies,
including our competitors or potential competitors. Some of these employees executed proprietary rights, non-disclosure and non-competition agreements
in connection with such previous employment. Although we take measures including by policy, procedure and contract to try to ensure that our employees
do not improperly use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have
used or disclosed confidential information or intellectual property, including trade secrets or other proprietary information, of any such employee’s former
employer. Litigation may be necessary to defend against these claims.
If we fail in prosecuting or 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
successfully prosecute or defend against such claims, litigation could result in substantial costs and distract management.
Obtaining and maintaining our 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 and annuity fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime
of the patent. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment
and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by
other means in accordance with the applicable rules, there
88
are situations in which noncompliance 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. Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to
respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we or our
existing or future licensors or collaborators fail to maintain the patents and patent applications covering our antibody candidates, our competitors might be
able to enter the market, which would have an adverse effect on our business.
Use of social media could give rise to liability, breaches of data security, or reputational harm.
We and our employees use social media to communicate internally and externally, as do our contractors, consultants, CROs, and third parties, including
clinical trial participants. While we have policies and procedures in place governing employee use of social media, there is risk that the use of social media
by us or our employees or third parties to communicate about our antibody candidates, technologies or business may give rise to liability, lead to the loss of
trade secrets or other intellectual property, or result in public exposure of personal information of our employees, clinical trial patients, customers, and
others. Furthermore, negative posts or comments about us, our clinical trials, or our antibody candidates, our technologies, and company generally in social
media could seriously damage our reputation, brand image, and goodwill. Any of these events could have a material adverse effect on our business,
prospects, operating results, and financial condition and could adversely affect the price of our common shares.
Our information technology systems, or those used by our CROs or other contractors or consultants, may fail or suffer security breaches, which could
adversely affect our business.
Despite the implementation of security measures, our information technology systems and data and those of our current or future CROs or other contractors
and consultants are vulnerable to compromise or damage from computer hacking, computer viruses, and malware (e.g., ransomware malicious software),
fraudulent activity, employee misconduct, human error, telecommunication and electrical failures, natural disasters, or other cybersecurity attacks or
accidents. Future acquisitions could expose us to additional cybersecurity risks and vulnerabilities from any newly acquired information technology
infrastructure. Cybersecurity attacks are constantly increasing in frequency and sophistication and are made by groups and individuals with a wide range of
motives (including industrial espionage) and expertise, including by organized criminal groups, “hacktivists,” nation states, and others. As a result of a
continued hybrid working environment, we may also face increased cybersecurity risks due to our reliance on internet technology and the number of our
employees who are working remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities. Furthermore, because the
techniques used to obtain unauthorized access to, or to sabotage systems change frequently and often are not recognized until launched against a target, we
may be unable to anticipate these techniques or implement adequate preventative measures. Further, as a company with an increasingly global presence,
our systems are subject to frequent attacks, which are becoming more commonplace in the industry, including attempted hacking, phishing attempts, such
as cyber-related threats involving spoofed or manipulated electronic communications, which increasingly represent considerable risk. Due to the nature of
some of the attacks described herein, there is a risk that an attack may remain undetected for a period of time. Even if identified, we may be unable to
adequately investigate or remediate incidents or breaches due to attackers increasingly using tools and techniques that are designed to circumvent controls,
to avoid detection, and to remove or obfuscate forensic evidence. While we continue to make investments to improve the protection of data and information
technology, including in the hiring of IT personnel, periodic cyber security awareness trainings, and improvements to IT infrastructure and controls, and
conduct regular testing of our systems, there can be no assurance that our efforts will prevent service interruptions or security breaches.
We and certain of our service providers are from time to time subject to cyberattack attempts or incidents and security incidents. Any cybersecurity incident
could adversely affect our business, by leading to, for example, the loss of trade secrets or other intellectual property, demands for ransom or other forms of
blackmail, or the unauthorized disclosure of personal or other sensitive information of our employees, clinical trial patients, customers, and others.
Although to our knowledge we have not experienced any significant cybersecurity incident to date, if such an event were to occur, it could seriously harm
our development programs and our business operations. We could be subject to breach notification requirements, regulatory actions taken by governmental
authorities, litigation under laws that protect the privacy of personal information, or other forms of legal proceedings, which could result in significant
liabilities or penalties, result in substantial costs and distract management. Further, a cybersecurity incident may disrupt our business or damage our
reputation, which could have a material adverse effect on our business, prospects, operating results, share price and shareholder value, and financial
condition. We could also incur substantial remediation costs, including the costs of investigating the incident, repairing or replacing damaged systems,
restoring normal business operations, implementing increased cybersecurity protections, and paying increased insurance premiums.
For example, the loss of clinical trial data from completed, ongoing or future clinical trials could result in delays in our regulatory approval efforts and
significantly increase our costs to recover or reproduce the data. If a security breach or other incident were to
89
result in the unauthorized access to or unauthorized use, disclosure, release or other processing of clinical trial data or personal data, it may be necessary to
notify individuals, governmental authorities, supervisory bodies, the media, and other parties pursuant to privacy and security laws. Likewise, we rely on
our third-party research institution collaborators for research and development of our product candidates and other third parties for the manufacture of our
product candidates and to conduct clinical trials, and similar events relating to their information technology systems could also seriously harm our business.
Any security compromise affecting us, our collaborators or our industry, whether real or perceived, could harm our reputation, erode confidence in the
effectiveness of our security measures, and lead to regulatory scrutiny. To the extent that any disruption or security breach were to result in a loss of, or
damage to, our data or systems, or inappropriate disclosure of confidential or proprietary or personal information, we could incur liability, our competitive
position could be harmed, and the further development and commercialization of our product candidates could be delayed, result in substantial costs and
distract management.
Risks Related to Employee Matters and Managing Growth
Our future growth and ability to compete depends on retaining our key personnel and recruiting additional qualified personnel.
Our success depends upon the contributions of our senior leaders, including our board of directors, our senior management, and other key scientific and
technical personnel, many of whom have been instrumental for us and have substantial experience with our antibody candidates and related technologies.
The loss of key senior management, managers and senior scientists could delay our research and development and clinical trial activities or impair our
ability operate the company effectively. In addition, the competition for qualified personnel in the biopharmaceutical and pharmaceutical field is
increasingly intense, and our future success depends upon our ability to attract, retain and motivate highly-skilled scientific, technical and managerial
employees. We face competition for personnel from other companies, universities, public and private research institutions and other organizations. If our
recruitment and retention efforts are unsuccessful, it may be difficult for us to implement our business strategy, which could have a material adverse effect
on our business.
We expect to expand our development, regulatory and sales and marketing capabilities, and as a result, we may encounter difficulties in managing our
growth, which could disrupt our operations.
We expect to continue to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of drug
and clinical development, regulatory affairs, medical affairs, commercialization, sales and marketing. To manage our growth, 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. Due to our limited financial resources and the limited experience of our management team in managing a company with such growth, we may
not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may
lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of
our business plans or disrupt our operations.
Risks Related to Our Common Shares
Future sales, or the possibility of future sales, of a substantial number of our common shares could adversely affect the price of the shares.
Sales of a substantial number of our common shares in the public market, or the perception in the market that the holders of a large number of shares intend
to sell shares, could reduce the market price of our common shares. We have registered and intend to continue to register all common shares that we may
issue under our equity compensation plans. Once registered, these common shares can be freely sold in the public market upon issuance, subject to volume
limitations applicable to affiliates who hold such shares. In addition, in connection with entering into the Collaboration Agreement, we entered into a Share
Subscription Agreement with Incyte, pursuant to which we issued and sold to Incyte 3,200,000 of our common shares. Incyte’s ability to sell these common
shares may be subject to certain limitations, including limitations on the volume of shares that may be sold during a given time period. Subject to that, these
shares can be freely sold in the public market. In addition, in connection with entering into the Lilly Collaboration Agreement, we entered into a Lilly Share
Subscription Agreement with Eli Lilly, pursuant to which we issued and sold to Eli Lilly 706,834 of our common shares.
Provisions of our articles of association or Dutch corporate law might deter acquisition bids for us that might be considered favorable and prevent or
frustrate any attempt to replace or remove the then board members.
Provisions of our articles of association may make it more difficult for a third party to acquire control of us or effect a change in our board of directors.
These provisions include:
90
•
•
•
•
the authorization of a class of preferred shares that may be issued to an independent special purpose foundation;
the possibility to appoint our board members for staggered terms;
a provision that our board members may only be removed by the general meeting of shareholders by a two-thirds majority of votes cast
representing more than 50% of our outstanding share capital (unless the removal was proposed by the board of directors); and
a requirement that certain matters, including an amendment of our articles of association, may only be brought to our shareholders for a
vote upon a proposal by our board of directors.
The board of directors can invoke a statutory cooling-off period of up to 250 days in situations described below. When such cooling-off period is invoked,
our general meeting of shareholders cannot dismiss, suspend or appoint members of the board of directors (or amend the provisions in our articles of
association dealing with those matters) unless those matters would be proposed by the board of directors. This cooling-off period could be invoked by the
board of directors in case:
a)
b)
shareholders, using either their shareholder proposal right or their right to request a general meeting of shareholders, propose an agenda
item for the general meeting of shareholders to dismiss, suspend or appoint a member of the board of directors (or to amend any provision
in the articles of association dealing with those matters); or
a public offer for the company is made or announced without the company's support, provided, in each case, that the board of directors
believes that such proposal or offer materially conflicts with the interests of the company and its business.
Under the Dutch Corporate Governance Code (DCGC), the board of directors may also invoke a response period of up to 180 days in case shareholders,
using either their shareholder proposal right or their right to request a general meeting of shareholders, propose an agenda item for the general meeting of
shareholders which may result in a change in our strategy (including through the dismissal of one or more of our board members). If this response period is
invoked, the shareholders concerned must give the board of directors the opportunity to respond to their intentions before their request is dealt with at a
general meeting of shareholders.
Our anti-takeover provision may prevent a beneficial change of control.
We adopted an anti-takeover measure pursuant to which our board of directors may, without shareholder approval, issue (or grant the right to acquire)
preferred shares. Pursuant to a call option agreement entered into with an independent special purpose foundation, we may issue an amount of preferred
shares up to 100% of our issued capital held by third parties immediately prior to the issuance of such preferred shares.
The preferred shares will be issued to the foundation for their nominal value, of which only 25% will be due upon issuance. The voting rights of our shares
are based on nominal value and as we expect our shares to continue to trade substantially in excess of nominal value, preferred shares issued at nominal
value can obtain significant voting power for a substantially reduced price and thus be used as a defensive measure. These preferred shares will have both a
liquidation and dividend preference over our common shares and will accrue cash dividends at a fixed rate. Subject to the foundation exercising its call
option under the call option agreement, the board may issue these preferred shares to protect us from influences that we believe do not serve our best
interests and threaten to undermine our continuity, independence and identity. These influences may include a third-party acquiring a significant percentage
of our common shares, the announcement of a public offer for our common shares, other concentration of control over our common shares or any other
form of pressure on us to alter our strategic policies. The foundation’s articles of association provide that it will act to serve the best interests of us, our
associated business and all parties connected to us, by opposing any influences that conflict with these interests and threaten to undermine our continuity,
independence and identity. This foundation is structured to operate independently of us.
Holders of our common shares outside the Netherlands may not be able to exercise preemptive rights.
In the event of an increase in our share capital, holders of our common shares are generally entitled under Dutch law to full preemptive rights, unless these
rights are excluded either by a resolution of the general meeting of shareholders, or by a resolution of the board (if the board has been designated by the
general meeting of shareholders for this purpose). Certain holders of our common shares outside the Netherlands, in particular U.S. holders of our common
shares, may not be able to exercise preemptive rights unless a registration statement under the Securities Act is declared effective with respect to our
common shares issuable upon exercise of such rights or an exemption from the registration requirements is available.
91
The rights of our shareholders may be different from the rights of shareholders in companies governed by the laws of U.S. jurisdictions.
We are a Dutch public company with limited liability (naamloze vennootschap). Our corporate affairs are governed by our articles of association and by the
laws governing companies incorporated in the Netherlands. The rights of shareholders and the responsibilities of members of our board may be different
from the rights and obligations of shareholders and directors in companies governed by the laws of U.S. jurisdictions. In the performance of their duties,
the members of our board are required by Dutch law to consider the interests of our company, its shareholders, its employees and other stakeholders, in all
cases with due observation of the principles of reasonableness and fairness. It is possible that some of these parties will have interests that are different
from, or in addition to, the interests of our shareholders.
We are not obligated to and do not comply with all the best practice provisions of the Dutch Corporate Governance Code. This may affect the rights of
our shareholders.
We are subject to the DCGC. The DCGC contains both principles and best practice provisions for board of directors, shareholders and general meetings of
shareholders, financial reporting, auditors, disclosure, compliance and enforcement standards. The DCGC applies to all Dutch companies listed on a
government-recognized stock exchange, whether in the Netherlands or elsewhere, including Nasdaq. The principles and best practice provisions apply to
our board (in relation to role and composition, conflicts of interest and independence requirements, board committees and remuneration), shareholders and
the general meeting of shareholders (for example, regarding anti-takeover protection and our obligations to provide information to our shareholders) and
financial reporting (such as external auditor and internal audit requirements). We do not comply with all the best practice provisions of the DCGC. As a
result, the rights of our shareholders may be affected and our shareholders may not have the same level of protection as a shareholder in another Dutch
public company with limited liability (naamloze vennootschap) listed in the Netherlands that fully complies with the DCGC.
Claims of U.S. civil liabilities may not be enforceable against us.
We are incorporated under the laws of the Netherlands. Most of our assets are located outside the United States. Currently, (i) there is no treaty in force
between the United States and the Netherlands for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and
commercial matters and (ii) both the Hague Convention on Choice of Court Agreements (2005) and the Hague Judgments Convention (2019) have entered
into force for the Netherlands, but have not entered into force for the United States. Consequently, a judgment rendered by a court in the United States will
not automatically be recognized and enforced by the competent Dutch courts. However, if a person has obtained a judgment rendered by a court in the
United States that is enforceable under the laws of the United States and files a claim with the competent Dutch court, the Dutch court will in principle give
binding effect to that United States judgment if (i) the jurisdiction of the United States court was based on a ground of jurisdiction that is generally
acceptable according to international standards, (ii) the judgment by the United States court was rendered in legal proceedings that comply with the Dutch
standards of proper administration of justice including sufficient safeguards (behoorlijke rechtspleging), (iii) binding effect of such United States judgment
is not contrary to Dutch public order (openbare orde) and (iv) the judgment by the United States court is not incompatible with a decision rendered between
the same parties by a Dutch court, or with a previous decision rendered between the same parties by a foreign court in a dispute that concerns the same
subject and is based on the same cause, provided that the previous decision qualifies for recognition in the Netherlands. Even if such a United States
judgment is given binding effect, a claim based thereon may, however, still be rejected if the United States judgment is not or no longer formally
enforceable. Moreover, if the United States judgment is not final (for instance when appeal is possible or pending) a competent Dutch court may postpone
recognition until the United States judgment will have become final, refuse recognition under the understanding that recognition can be asked again once
the United States judgment will have become final, or impose as a condition for recognition that security is posted. A competent Dutch court may deny the
recognition and enforcement of punitive damages or other awards. Moreover, a competent Dutch court may reduce the amount of damages granted by a
United States court and recognize damages only to the extent that they are necessary to compensate actual losses or damages. Thus, certain investors may
not be able, or experience difficulty, to enforce a judgment obtained in a United States court against us or our officers (functionarissen).
Our articles of association include a U.S. federal forum selection clause designating federal courts as the sole and exclusive forum for certain types of
actions and proceedings that may be initiated by our shareholders, which could limit our shareholders’ ability to obtain a favorable judicial forum for
disputes with us or our directors, officers, or employees.
Our articles of association provide that, unless we consent in writing to an alternative forum, the sole and exclusive forum for any complaint asserting a
cause of action arising under the Securities Act, to the fullest extent permitted by applicable law, shall be the federal district courts of the United States of
America (the “Federal Forum Provision”). The Federal Forum Provision in our articles of association may impose additional litigation costs on
shareholders in pursuing any such claims. Additionally, the forum selection clause may limit our shareholders’ ability to bring a claim in a forum that they
find favorable for disputes with us or our directors,
92
officers or employees, which may discourage such lawsuits against us and our directors, officers and employees even though an action, if successful, might
benefit our shareholders. In addition, while the Delaware Supreme Court ruled in March 2020 that federal forum selection provisions purporting to require
claims under the Securities Act be brought in federal court were “facially valid” under Delaware law, there is uncertainty as to whether other courts will
enforce our Federal Forum Provision. If the Federal Forum Provision is found to be unenforceable, we may incur additional costs associated with resolving
such matters. The Federal Forum Provision may also impose additional litigation costs on shareholders who assert that the provision is not enforceable or
invalid. The Court of Chancery of the State of Delaware and the United States District Court for the District of Massachusetts may also reach different
judgments or results than would other courts, including courts where a shareholder considering an action may be located or would otherwise choose to
bring the action, and such judgments may be more or less favorable to us than our shareholders.
We are no longer an “emerging growth company” or a “smaller reporting company” , and as a result we are subject to certain enhanced disclosure
requirements which will require us to incur significant expenses and expend time and resources.
We are no longer an “emerging growth company” or a “smaller reporting company,” and as a result, we are required to comply with various disclosure and
compliance requirements that did not previously apply, such as the auditor attestation requirements of The Sarbanes-Oxley Act of 2002 (SOX) Section
404(b), the requirement that we hold a nonbinding advisory vote on executive compensation and obtain shareholder approval of any golden parachute
payments not previously approved, and the requirement to provide full and more detailed executive compensation disclosure. Compliance with these
additional requirements increases our legal and financial compliance costs and causes management and other personnel to divert attention from operational
and other business matters to these additional public company reporting requirements. In addition, if we are not able to comply with changing requirements
in a timely manner, the market price of our stock could decline and we could be subject to delisting proceedings by the stock exchange on which our
common shares are listed, or sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and
management resources.
We may be classified as a passive foreign investment company (PFIC) for U.S. federal income tax purposes, which could result in adverse U.S. federal
income tax consequences to U.S. investors in our common shares.
Based on the value of our assets, including goodwill, and composition of our income, assets and operations for the taxable year 2023, we do not believe we
were a PFIC for U.S. federal income tax purposes for that taxable year. A non-U.S. company generally will be considered a PFIC for any taxable year if (i)
at least 75% of its gross income is passive income (including interest income), or (ii) at least 50% of the value of its assets (based on an average of the
quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income. The value of our
assets generally is determined by reference to the market price of our common shares, which may fluctuate considerably. In addition, the composition of
our income and assets is affected by how, and how quickly, we spend the cash we raise. It is possible the Internal Revenue Service could determine that we
were a PFIC for the taxable year 2023. If we were to be treated as a PFIC for any taxable year during which a U.S. Holder (as defined below) holds a
common share, certain adverse U.S. federal income tax consequences could apply to such U.S. Holder. Once treated as a PFIC, for any taxable year in
which a U.S. Holder owns equity in such foreign corporation, a foreign corporation will generally continue to be treated as a PFIC for all subsequent
taxable years with respect to such U.S. Holder. If we were to be a PFIC, “excess distributions” (as such term is defined in the United States Internal
Revenue Code of 1986, as amended (the U.S. Tax Code)) to a U.S. Holder, and any gain recognized by a U.S. Holder on a disposition of our common
shares would be taxed in potentially unfavorable ways. Among other consequences, our dividends would be taxed at the regular rates applicable to ordinary
income, rather than the reduced rate applicable to certain dividends received by an individual from a qualified foreign corporation, and, to the extent that
they constituted excess distributions, certain interest charges may apply, and gains on the sale of our shares would be treated in the same way as excess
distributions. In addition, the U.S. Holder would be subject to detailed reporting obligations. The tests for determining PFIC status are applied annually and
it is difficult to make accurate predictions of future income and assets, which are relevant to the determination of any future PFIC status. As such, we
cannot provide any assurances regarding our PFIC status for any past, current or future taxable years. Further, we cannot provide any assurances that we
will furnish to any U.S. Holder information that may be necessary to comply with the aforementioned reporting and tax payment obligations. U.S. Holders
should consult their tax advisors regarding the potential application of these rules to their investment in our common shares, including the potential
availability and advisability of an election to treat us as a qualified electing fund or a mark-to-market election. A “U.S. Holder” is a holder who, for U.S.
federal income tax purposes, is a beneficial owner of our common shares and is:
(1)
(2)
(3)
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
93
(4)
a trust that (a) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the
meaning of Section 7701(a)(30) of the U.S. Tax Code) or (b) has a valid election in effect to be treated as a United States person for U.S.
federal income tax purposes.
If a U.S. Holder is treated as owning at least 10% of our common shares, such holder may be subject to adverse U.S. federal income tax consequences.
If a U.S. Holder is treated as owning (directly, indirectly or constructively) at least 10% of the value or voting power of our common shares, such U.S.
Holder may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in our group (if any) as such term is defined in
the U.S. Tax Code. A United States shareholder of a controlled foreign corporation may be required to report annually and include in its U.S. taxable
income, as ordinary income, its pro rata share of “Subpart F income,” “global intangible low-taxed income” and investments in U.S. property by the
controlled foreign corporation, regardless of whether the controlled foreign corporation makes any distributions. An individual that is a United States
shareholder with respect to a controlled foreign corporation generally would not be allowed certain tax deductions or foreign tax credits that would be
allowed to a United States shareholder that is a corporation. Failure to comply with these reporting obligations may subject a United States shareholder to
significant monetary penalties and may extend the statute of limitations with respect to such United States shareholder’s U.S. federal income tax return for
the year for which reporting was due. We cannot provide any assurances that we will assist investors in determining whether we or any of our future non-
U.S. subsidiaries is treated as a controlled foreign corporation or whether such investor is treated as a United States shareholder with respect to any such
controlled foreign corporations. Further, we cannot provide any assurances that we will furnish to any United States shareholders information that may be
necessary to comply with the aforementioned reporting and tax payment obligations. U.S. Holders should consult their tax advisors regarding the potential
application of these rules to their investment in our common shares. The risk of being subject to increased taxation may deter our current shareholders from
increasing their investment in us and others from investing in us, which could impact the demand for, and value of, our common shares.
General Risk Factors
The price of our common shares may be volatile and may fluctuate due to factors beyond our control.
The share price of publicly traded emerging biopharmaceutical and drug discovery and development companies has been highly volatile and is likely to
remain highly volatile in the future. The market price of our common shares may fluctuate significantly due to a variety of factors, including:
•
•
•
•
•
•
•
•
•
•
•
•
positive or negative results of testing and clinical trials by us, strategic partners or competitors;
delays in entering into strategic relationships with respect to development and/or commercialization of our antibody candidates or entry into
strategic relationships on terms that are not deemed to be favorable to us;
technological innovations or commercial product introductions by us or competitors;
changes in government regulations;
developments concerning proprietary rights, including patents and litigation matters;
public concern relating to the commercial value or safety of any of our antibody candidates;
financing or other corporate transactions;
publication of research reports or comments by securities or industry analysts;
general market conditions in the pharmaceutical industry or in the economy as a whole;
political instability in the United States and Europe, including the failure of the United States Federal government to raise the debt ceiling;
global geopolitical instability, including the ongoing conflicts in Europe and the Middle east; or
other events and factors, many of which are beyond our control.
These and other market and industry factors may cause the market price and demand for our common shares to fluctuate substantially, regardless of our
actual operating performance, which may limit or prevent investors from readily selling their common shares and
94
may otherwise negatively affect the liquidity of our common shares. In addition, the stock market in general, and biopharmaceutical companies in
particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these
companies.
Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and share
price.
The global economy, including credit and financial markets, has recently experienced extreme volatility and disruptions, including severely diminished
liquidity and credit availability, rising interest and inflation rates, declines in consumer confidence, declines in economic growth, increases in
unemployment rates and uncertainty about economic stability. If the equity and credit markets continue to deteriorate or the Netherlands or the United
States enters a recession, it may make any necessary debt or equity financing more difficult to obtain in a timely manner or on favorable terms, more costly
or more dilutive. In addition, there is a risk that one or more of our CROs, suppliers or other third-party providers may not survive an economic downturn
or recession. As a result, our business, results of operations and price of our common shares may be adversely affected.
Business interruptions could adversely affect our operations.
Our operations are vulnerable to interruption by fire, severe weather conditions, power loss, telecommunications failure, terrorist activity, public health
crises and pandemic diseases, such as COVID-19, and other natural and man-made disasters or events beyond our control. Our facilities are located in
regions that experience severe weather from time to time. We have not undertaken a systematic analysis of the potential consequences to our business and
financial results from a major tornado, flood, fire, earthquake, power loss, terrorist activity, public health crisis, pandemic diseases or other disasters and do
not have a recovery plan for such disasters. In addition, we do not carry sufficient insurance to compensate us for actual losses from interruption of our
business that may occur, and any losses or damages incurred by us could harm our business. The occurrence of any of these business disruptions could
seriously harm our operations and financial condition and increase our costs and expenses.
Because we do not expect to pay cash dividends for the foreseeable future, any returns on an investment in our common shares will likely depend
entirely upon any future appreciation in the price of our common shares, which is uncertain.
We have not paid any cash dividends since our incorporation. Even if future operations lead to significant levels of distributable profits, we currently intend
that any earnings will be reinvested in our business and that cash dividends will not be paid until we have an established revenue stream to support
continuing cash dividends. Payment of any future dividends to shareholders will in addition effectively be at the discretion of the general meeting, upon
proposal of the board of directors, after taking into account various factors including our business prospects, cash requirements, financial performance and
new product development. In addition, payment of future cash dividends may be made only if our shareholders’ equity exceeds the sum of our paid-in and
called-up share capital plus the reserves required to be maintained by Dutch law or by our articles of association. Accordingly, investors cannot rely on cash
dividend income from our common shares and any returns on an investment in our common shares will likely depend entirely upon any future appreciation
in the price of our common shares. In addition, the low trading volume of our common shares may adversely affect the trading price of our common shares,
and our shareholders may not be able to sell their common shares for a price higher than the price they paid for our common shares.
If securities or industry analysts publish inaccurate or unfavorable research about our business, the price of our common shares and our trading
volume could decline.
The trading market for our common shares depends in part on the research and reports that securities or industry analysts publish about us or our business.
If one or more of the analysts who cover us downgrade our common shares or publish inaccurate or unfavorable research about our business, the price of
our common shares would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our
common shares could decrease, which might cause the price of our common shares and trading volume to decline.
95
We will continue to incur increased costs as a result of operating as a public company with limited liability (naamloze vennootschap), and our
management team is required to devote substantial time to new compliance initiatives and corporate governance practices.
As a public company, and particularly now that we no longer qualify as an emerging growth company or a smaller reporting company, we will continue to
incur significant legal, accounting and other expenses related to our operation as a public company. The Sarbanes-Oxley Act of 2002 (SOX), the Dodd-
Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the Nasdaq Global Market, or Nasdaq, and other applicable securities
rules and regulations impose various requirements on reporting public companies, including the establishment and maintenance of effective disclosure and
financial controls and corporate governance practices. Our board of directors and other personnel continues to devote a substantial amount of time to these
compliance initiatives. Moreover, these rules and regulations have and will continue to increase our legal and financial compliance costs and make some
activities more time-consuming and costly.
These rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in
practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding
compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.
Pursuant to Section 404(a) of SOX (Section 404) we are required to furnish a report by our management on our internal control over financial reporting
with our Annual Report on Form 10-K. Additionally, we are required to include an attestation report on internal control over financial reporting issued by
our independent registered public accounting firm. To maintain compliance with Section 404(a), we engage in a process to document and evaluate our
internal control over financial reporting, which is both costly and challenging. In this regard, we continue to dedicate internal resources and have engaged
outside consultants and adopted a detailed work plan to assess and document the adequacy of our 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 that we will not be able to maintain effective internal
control over financial reporting as required by Section 404. Material weaknesses or significant deficiencies in our internal control over financial reporting
could also reduce our ability to obtain financing or could increase the cost of any financing we obtain. If we identify one or more material weaknesses, it
could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.
The increasing focus on environmental sustainability and social initiatives could increase our costs, harm our reputation and adversely impact our
financial results.
There has been increasing public focus by investors, patients, environmental activists, the media and governmental and nongovernmental organizations on
a variety of environmental, social and other sustainability matters. We may experience pressure to make commitments relating to sustainability matters that
affect us, including the design and implementation of specific risk mitigation strategic initiatives relating to sustainability. Expectations regarding the
management of ESG initiatives continues to evolve rapidly. While we may from time to time engage in various initiatives (including but not limited to
voluntary disclosures, policies, or goals) to improve our ESG profile or respond to stakeholder expectations, we cannot guarantee that these initiatives will
have the desired effect. If we are not effective in addressing environmental, social and other sustainability matters affecting our business, or setting and
meeting relevant sustainability goals, our reputation and financial results may suffer. In addition, even if we are effective at addressing such concerns, we
may experience increased costs as a result of executing upon our sustainability goals that may not be offset by any benefit to our reputation, which could
have an adverse impact on our business and financial condition.
In addition, this emphasis on environmental, social and other sustainability matters has resulted and may result in the adoption of new laws and regulations,
including new reporting requirements. If we fail to comply with new laws, regulations or reporting requirements, our reputation and business could be
adversely impacted.

Item 1C. Cybersecurity
Cybersecurity Risk Management and Strategy
96
We have established policies and processes for assessing, identifying, and managing material risk from cybersecurity threats, and have integrated these
processes into our overall risk management systems and processes. We routinely assess material risks from cybersecurity threats, including any potential
unauthorized occurrence on or conducted through our information systems that may result in adverse effects on the confidentiality, integrity, or availability
of our information systems or any information residing therein. We design and are assessing our cybersecurity risk management program based on the
ISO27001:2022 standard. This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use the
ISO27001:2022 as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business.
We conduct periodic risk assessments to identify cybersecurity threats, as well as assessments in the event of a material change in our business practices
that may affect information technology systems that are vulnerable to cybersecurity threats. These risk assessments include identification of reasonably
foreseeable internal and external risks, the likelihood and potential damage that could result from such risks, and the sufficiency of existing policies,
procedures, systems, and safeguards in place to manage such risks.
Following these risk assessments, we re-design, implement, and maintain reasonable safeguards to minimize identified risks; reasonably address any
identified gaps in existing safeguards; and regularly monitor the effectiveness of our safeguards. Primary responsibility for assessing, monitoring and
managing our cybersecurity risks rests with our IT department who reports to our Chief Operating Officer, to manage the risk assessment and mitigation
process. The cybersecurity risk management program also includes tools and activities to prevent, detect, and analyze current and emerging cybersecurity
threats, and plans and strategies to address threats and incidents.
As part of our overall risk management system, we monitor and test our safeguards and train our employees on these safeguards, in collaboration with IT
and management. Personnel at all levels and departments are made aware of our cybersecurity policies through trainings.
We engage consultants, or other third parties in connection with our risk assessment processes. These service providers assist us with designing and
implementing our cybersecurity policies and procedures, as well as to monitor and test our safeguards, and investigations on an as needed basis. We
contractually require third-party service providers to implement and maintain appropriate security measures, consistent with all applicable laws, to
implement and maintain reasonable security measures in connection with their work with us.
We have not encountered cybersecurity challenges that have materially impaired our operations or financial standing. For additional information regarding
risks from cybersecurity threats, please see section “Risk Factors --Our information technology systems, or those used by our CROs or other contractors or
consultants, may fail or suffer security breaches, which could adversely affect our business,” in this Annual Report on Form 10-K.
Cybersecurity governance
One of the key functions of our board of directors is informed oversight of our risk management process, including risks from cybersecurity threats. Our
board of directors is responsible for monitoring and assessing strategic risk exposure, and our executive officers are responsible for the day-to-day
management of the material risks we face. Our board of directors administers its cybersecurity risk oversight function directly as a whole, as well as
through the audit committee.
Our Chief Operating Officer and management team are primarily responsible for assessing and managing our material risks from cybersecurity threats with
assistance from the Head of IT Security and Compliance, the supporting internal team and support of third-party service providers.
Our Chief Operating Officer oversees our cybersecurity policies and processes, including those described in “Cybersecurity Risk Management and
Strategy” above.
Our Chief Operating Officer and Head of IT Security provide periodic briefings to the audit committee regarding our company’s cybersecurity risks and
activities, including any recent cybersecurity incidents and related responses, cybersecurity systems testing, activities of third parties, and policy and
procedures, and changes in applicable law or regulations concerning such subject matter. Our audit committee is charged with, and is able to pass
resolutions relating to the application of information and communication technology by the Company, including risks relating to cybersecurity. Moreover,
periodic briefings are also provided to the board of directors relating to our cybersecurity risks and activities, including any recent cybersecurity incidents
and related responses, cybersecurity systems testing, activities of third parties, and policy and procedures, and changes in applicable law or regulations
concerning such subject matter.
97
Our team that is responsible for assessing and our material risks from cybersecurity threats, including our Chief Operating Officer, Chief Financial Officer,
and Senior Director, Head of IT Security and Compliance, has more than a combined 30 years of risk management experience. Our team’s experience
includes the Senior Director, Head of IT Security and Compliance, who has an extensive (+25 years) track record on cyber- and IT risks management,

Overview
General
We are a clinical-stage oncology company developing innovative antibody therapeutics. Our pipeline of full-length human multispecific antibody
candidates is generated from our proprietary technology platforms, which are able to generate a diverse array of antibody binding domains, or Fabs, against
virtually any target. Each antibody binding domain consists of a target-specific heavy chain paired with a common light chain. Multiple binding domains
can be combined to produce novel multispecific antibodies that bind to a wide range of targets and display novel and innovative biology. These platforms,
referred to as Biclonics® and Triclonics®, allow us to generate large numbers of diverse panels of bispecific and trispecific antibodies, respectively, which
can then be functionally screened in large-scale cell-based assays to identify those unique molecules that possess novel biology, which we believe are best
suited for a given therapeutic application. Further, by binding to multiple targets, Biclonics® and Triclonics® may be designed to provide a variety of
mechanisms of action, including simultaneously blocking receptors that drive tumor cell growth and survival and mobilizing the patient’s immune response
by engaging T cells, and/or activating various killer cells to eradicate tumors.
Our technology platforms employ an assortment of patented technologies and techniques to generate human antibodies. We utilize our patented MeMo®
mouse to produce a host of antibodies with diverse heavy chains and a common light chain that are capable of binding to virtually any antigen target. We
use our patented heavy chain and CH3 domain dimerization technology to generate substantially pure bispecific and trispecific antibodies. We employ our
patented Spleen to Screen® technology to efficiently screen panels of diverse heavy chains, designed to allow us to rapidly identify Biclonics® and
Triclonics® therapeutic candidates with differentiated modes of action for pre-clinical and clinical testing.
Using our Biclonics® platform we have produced, and are currently developing, the following candidates: MCLA-128 (zenocutuzumab) for the potential
treatment of solid tumors that harbor Neuregulin 1 (NRG1) gene fusions as a monotherapy; MCLA-158 (petosemtamab) for the potential treatment of solid
tumors; MCLA-129, for the potential treatment of lung and other solid tumors, which is subject to a collaboration and license agreement, which permits
Betta Pharmaceuticals Co. Ltd. (Betta) to exclusively develop MCLA-129 in China, while Merus retains full ex-China rights and MCLA-145 for the
potential treatment of solid tumors. Furthermore, we have a pipeline of proprietary antibody candidates in pre-clinical development and intend to further
leverage our Biclonics® and Triclonics® technology platforms to identify multispecific antibody candidates and advance them into clinical development.
Funding Our Operations
We are a clinical-stage company and have not generated any revenue from product sales. We expect to incur significant expenses and operating losses for
the foreseeable future as we advance our antibody candidates from discovery through pre-clinical development and into clinical trials and seek regulatory
approval and pursue commercialization of any approved antibody candidate. In addition, if we obtain regulatory approval for any of our antibody
candidates, if appropriate, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution,
and compliance.
We anticipate that we will require additional financing to support our continuing operations. Until such time as we can generate significant revenue from
product sales, if ever, we expect to finance our operations through a combination of public or private equity or debt financings or other sources, which may
include collaborations, business development and licensing opportunities with third parties. Adequate additional financing may not be available to us on
acceptable terms, or at all. For example, the trading prices for our and other biopharmaceutical companies’ stock have been highly volatile as a result of
disruptions and extreme volatility in the global
100
economy, including rising inflation and interest rates, declines in economic growth, global instability including the ongoing geopolitical conflicts in Europe
and the Middle East and the residual impact of the COVID-19 pandemic. As a result, we may face difficulties raising capital through sales of our common
stock and any such sales may be on unfavorable terms. See “Impact of COVD-19 pandemic” below and “Risk Factors—Risks Related to Our Business and
Industry—The COVID-19 pandemic has and may continue to adversely impact our business, including our pre-clinical studies and clinical trials, financial
condition and results of operations” in Part I, Item 1A of this Annual Report on Form 10-K. Our inability to raise capital as and when needed would have a
negative impact on our financial condition and our ability to pursue our business strategy. We will need to generate significant revenue to achieve
profitability, and we may never do so.
Based on our current operating plan, we expect that our existing cash, cash equivalents and marketable securities of $411.7 million as of December 31,
2023 will fund our operations into 2027. We have based this estimate on assumptions that may prove to be wrong, particularly as the process of testing
product candidates in clinical trials is costly and the timing of progress in these trials is uncertain. As a result, we could use our capital resources sooner
than we expect.
Clinical Programs
Petosemtamab (MCLA-158: EGFR x LGR5 Biclonics®): Solid Tumors
Granted Fast Track Designation (FTD) for the treatment of patients with recurrent or metastatic head & neck squamous cell carcinoma (HNSCC),
investigation continues in dose expansion in the phase 1/2 trial with petosemtamab monotherapy in previously treated HNSCC, as well as in combination
with pembrolizumab as front-line therapy ongoing; planned initiation of 2L+ CRC cohort in 2024.
Petosemtamab is in clinical development in the expansion part of a Phase 1/2 open-label, multicenter trial evaluating petosemtamab monotherapy in
patients with advanced solid tumors, including previously treated advanced (recurrent or metastatic) head and neck squamous cell carcinoma (HNSCC).
We are currently evaluating a cohort of patients receiving petosemtamab in combination with pembrolizumab with untreated HNSCC expressing PD-L1
(CPS > 1) to evaluate safety and clinical activity in this population. We believe initial safety data from this single arm cohort may support the initiation of
a first-line registration trial with this combination. We plan to report initial interim clinical data from this cohort in the second quarter of 2024. Among the
initial patients dosed in the front-line combination, the safety profile has been observed to be generally well tolerated.
We are currently evaluating approximately 40 patients in previously treated (2L/3L) HNSCC with petosemtamab monotherapy at the 1100 or 1500 mg dose
levels to confirm a suitable dose for future potential randomized trials. We plan to share clinical data from this cohort in the second half of 2024. Based on
these data and additional information and analyses, we anticipate potentially initiating a randomized phase 3 trial of petosemtamab monotherapy, or
investigators’ choice of single agent chemotherapy or cetuximab in 2L/3L HNSCC. We anticipate such a trial could potentially start in mid-2024. We
believe a randomized registration trial in HNSCC with an overall response rate endpoint could potentially support accelerated approval and the overall
survival results from the same study could potentially verify its clinical benefit to support regulatory approval.
At the American Association of Cancer Research (AACR) Annual Meeting 2023, Merus provided interim data on 49 2L+ HNSCC patients that were
treated with petosemtamab at the recommended phase 2 dose of 1500 mg intravenous every two weeks. 43 patients were evaluable for efficacy. As of a
February 1, 2023 data cutoff date, the ORR was 37.2% by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 per investigator assessment.
Petosemtamab continued to demonstrate a manageable safety profile. We plan to provide updated efficacy, durability and safety data of this cohort in the
second half of 2024.
Fast Track Designation
The FDA has granted Fast Track Designation for the investigation of petosemtamab for the treatment of patients with recurrent or metastatic HNSCC
whose disease has progressed following treatment with platinum-based chemotherapy and an anti-programmed cell death protein 1 (anti-PD-1) antibody.
Fast Track is a designation designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill unmet medical needs.
In 2024, we plan on evaluating petosemtamab in 2L colorectal cancer patients.
Zenocutuzumab, or “Zeno” (MCLA-128: HER3 x HER2 Biclonics®): NRG1 gene fusion (NRG1+) cancers and other solid tumors Sufficient clinical
data expected in 1H24 to support potential BLA submissions in NRG1+ non-small cell lung cancer (NSCLC) and NRG1+ pancreatic cancer (PDAC).
We continue to enroll patients in the Phase 1/2 eNRGy trial to assess the safety and anti-tumor activity of Zeno monotherapy in NRG1+ cancers.
101
We presented a clinical update on Zeno in NRG1+ cancer in the Phase 1/2 eNRGy trial and Early Access Program (EAP) at the European Society for
Medical Oncology (ESMO) 2023 held in Madrid, Spain on October 20-24, 2023. The presentations consisted of a mini-oral lecture titled: Durable efficacy
of zenocutuzumab, a HER2 x HER3 bispecific antibody, in advanced NRG1 fusion-positive (NRG1+) non-small cell lung cancer (NSCLC) and a poster
presentation titled: Durable efficacy of zenocutuzumab, a HER2 x HER3 bispecific antibody in advanced NRG1 fusion-positive (NRG1+) pancreatic ductal
adenocarcinoma (PDAC).
Observations in the NRG1+ NSCLC presentation include:
As of the July 31, 2023 data cutoff date, 105 patients with NRG1+ NSCLC were treated with Zeno. 78 patients with measurable disease were treated by
February 13, 2023, allowing for the potential for ≥ 24 weeks follow-up, and who met the criteria for the primary analysis population. Patients who were
excluded from the efficacy include two who discontinued early for reasons not related to progressive disease; two patients that received a prior anti-HER3
inhibitor; two patients with other genetic driver mutations; one patient with concomitant anti-cancer medication use; and one patient with baseline scan > 5
weeks before first dose; and a patient with non-measurable disease. As of the data cutoff date, interim results from the primary analysis population (n=78)
included:
•
•
•
37.2% (29/78; 95% Cl: 26.5-48.9) overall response rate (ORR) per RECIST (Response Evaluation Criteria in Solid Tumors) v1.1 by
investigator assessment;
61.5% (95% CI: 49.8 - 72.3) clinical benefit rate (CBR); and
14.9 months median duration of response (DOR) and 20 patients were continuing treatment as of the data cutoff date.
Observations in the NRG1+ PDAC presentation include:
As of the July 31, 2023 data cutoff date, 44 patients with NRG1+ PDAC were treated with Zeno. 33 patients with measurable disease were treated by
February 13, 2023, allowing for the potential for ≥ 24 weeks follow-up, and who met the criteria for the primary analysis population. Patients who were
excluded from the efficacy population include two patients with other genetic driver mutations; one patient with prior anti-HER3 therapy; one patient with
a nonfunctional NRG1 fusion; and one patient with a baseline scan > 5 weeks before the first dose. As of the data cutoff date, interim results from the
primary analysis population (n=33) included:
•
•
•
•
•
•
42.4% (95% CI, 25.5–60.8) ORR per RECIST v1.1 by investigator assessment; 1 (3%) patient achieved a complete response, and 13 (39%)
patients achieved a partial response;
72.7% (95% CI, 54-87) CBR;
82% of patients exhibited tumor reduction;
Of 27 patients evaluable for CA 19-9 levels, 21 (78%) showed a ≥ 50% decrease in CA 19-9 values from baseline;
Median DOR was 9.1 months (95% CI, 5.5–12.0); and
6 patients (18%) were continuing treatment as of the data cutoff date.
Safety findings from both presentations: Zeno was generally well tolerated among the 189 NRG1+ cancer patients who were treated with 750 mg Q2W
monotherapy, with 6% of patients experiencing related grade 3-4 toxicities.
We expect we will have sufficient clinical data in the first half of 2024 to support potential BLA submissions in both NRG1+ NSCLC and NRG1+ PDAC.
In June and July 2023, respectively, we announced that Zeno has been granted two breakthrough therapy designations (BTD) by the U.S. FDA for (i) the
treatment of patients with advanced unresectable or metastatic NRG1 fusion (NRG1+) pancreatic cancer following progression with prior systemic therapy
or who have no satisfactory alternative treatment options; and (ii) the treatment of patients with advanced unresectable or metastatic NRG1 fusion
(NRG1+) non-small cell lung cancer (NSCLC), following progression with prior systemic therapy.
In August 2020, Zeno was granted orphan drug designation by the U.S. FDA for the treatment of pancreatic cancer and in January 2021, we announced that
Zeno received Fast Track Designation for the treatment of patients with metastatic solid tumors harboring NRG1 gene fusions that have progressed on
standard-of-care therapy.
We believe that obtaining a commercialization partnership agreement will be an essential step in bringing Zeno to patients with NRG1+ cancer, if
approved.
We are also evaluating Zeno in combination with an ADT (enzalutamide or abiraterone) in CRPC, irrespective of NRG1+ status. Enrollment is paused and
we plan to continue monitoring these patients. We also continue to monitor patients treated with Zeno in combination with afatinib but no further
enrollment is planned at this time.
102
We are also conducting ongoing translational work on potential biomarkers outside of NRG1+ cancer which may support development opportunities for
Zeno in additional areas of unmet need.
MCLA-129 (EGFR x c-MET Biclonics®): Solid Tumors
Investigation of MCLA-129 continues in the MET ex14 NSCLC expansion cohort in the phase 1/2 trial; MCLA-129 in combination with chemotherapy in
2L+ EGFR mutant (EGFRm) NSCLC in 2024.
In December at the ESMO Asia Congress 2023 interim data was presented on MCLA-129 from ongoing expansion cohorts in NSCLC and in previously
treated HNSCC.
Patients with advanced/metastatic EGFRm NSCLC were treated with MCLA-129 combined with osimertinib as first-line therapy or in the 2L+ setting after
progression on osimertinib. In the 1L, all 16 evaluable patients experienced tumor shrinkage. In the 2L+ setting, 34 patients were evaluable for response
with 11 experiencing confirmed PRs and 1 unconfirmed PR by RECIST v1.1. per investigator assessment. In the 60 NSCLC patients treated with MCLA-
129 plus osimertinib, the safety profile shows adverse events associated with EGFR and c-MET inhibition as well as interstitial lung disease. We continue
to follow these patients to evaluate potential for biomarkers to maximize efficacy, while proactively addressing safety signals seen to date.
Based on the results to date, we are encouraged by the potential for MCLA-129 in the treatment of cancer are evaluating focused investment opportunities.
We plan to start a cohort of MCLA-129 in combination with chemotherapy in 2L+ EGFRm NSCLC in 2024. Additionally, we remain interested and are
continuing investigation of cohort B evaluating MCLA-129 in patients with MET exon14 skipping NSCLC. We also remain interested in exploring
partnering MCLA-129 with other companies to sufficiently resource the development of MCLA-129 and potential benefit it may have for patients.
MCLA-145 (CD137 x PD-L1 Biclonics®): Solid Tumors
Investigation continues of the phase 1 trial of MCLA-145 in combination with pembrolizumab.
MCLA-145 is in clinical development in a global, phase 1, open-label, clinical trial evaluating MCLA-145 in patients with solid tumors. The trial is in the
dose expansion phase, and we continue to monitor and evaluate patients on treatment with the combination of MCLA-145 with pembrolizumab.
Collaborations and Other Revenue Generating Agreements
Refer to Item 1, “Business—Collaboration Agreements,” and Note 12, “Collaborations,” of the notes to our Consolidated Financial Statements included

Our revenue from each collaborator consists of revenue recognized from the amortization of deferred revenue related to upfront payments for licenses or
options to obtain licenses in the future, research and development services reimbursement revenue earned and milestone payments earned under
collaboration and license agreements with our collaboration partners.
103
Collaboration revenue for the year ended December 31, 2023 increased $2.4 million as compared to the year ended December 31, 2022, primarily as a
result of increases in Incyte revenue of $2.6 million, and Lilly revenue of $1.0 million, offset by decreases in Other revenue of $1.2 million. The increase in
Incyte revenue is primarily the result of increases in milestone revenue of $5.0 million and upfront payment amortization of $0.4 million due to changes in
foreign exchange rates, partially offset by decreases in reimbursement revenue of $2.8 million. The increase in Lilly revenue is primarily the result of
increases in reimbursement revenue of $0.7 million and upfront payment amortization of $0.3 million. The decrease in Other revenue is primarily the result
of decreases in milestone revenue of $1.0 million and upfront payment amortization of $0.2 million.
As of December 31, 2023, we have total deferred revenue of $42.3 million, which primarily relates to the upfront payment received under our Incyte
collaboration agreement and Lilly collaboration agreement. The original payment of $73.3 million from the Incyte collaboration agreement is expected to
be recognized over the next two years. The original payment of $27.4 million from the Lilly collaboration agreement is expected to be recognized over time
using a cost-to-cost measure of progress toward the development of a lead compound for each respective target.

Research and development costs consist principally of the costs associated with our research and development activities, conducting pre-clinical studies and
clinical trials, and activities related to our regulatory filings. Our research and development expenses consist of:
•
•
•
•
salaries for research and development staff and related expenses, including share-based compensation expenses;
expenses incurred under agreements with contract research organizations (CROs) contract manufacturing organizations, and consultants that
conduct and support clinical trials and pre-clinical studies;
costs to enhance our platform technologies, develop product candidates, including raw materials and supplies, product testing, and facility
related expenses; and
amortization and depreciation of tangible and intangible fixed assets used to develop our product candidates.
Note that we do not allocate employee-related costs, depreciation, rental and other indirect costs to specific research and development programs because
these costs are deployed across multiple programs under research and development and, as such, are separately classified as unallocated research and
development expenses.
Research and development expense for the year ended December 31, 2023 decreased $8.8 million as compared to the year ended December 31, 2022,
primarily as a result of decreases in external clinical services and drug manufacturing costs, including costs to fulfill our obligations under our collaboration
agreements related to our programs of $18.8 million and partner expenses of $0.7 million, partially offset by increases to personnel related expenses
including share-based compensation of $6.5 million due to an increase in employee headcount, consultancy expenses of $2.9 million, facilities expenses of
$1.1 million, consumables expenses of $0.3 million, and travel expenses of $0.3 million.
Research and development activities are central to our business model. We expect to continue to incur significant research and development costs for the
foreseeable future as we continue to enhance our platform technologies, our development programs progress, as we continue to support the clinical trials of
our antibody candidates as treatments for various cancers and as we move these candidates into additional clinical trials. There are numerous factors
associated with the successful commercialization of any of our antibody candidates, including future trial design and various regulatory requirements, many
of which cannot be determined with accuracy at this time based on our stage of development. Additionally, future commercial and regulatory factors
beyond our control may impact our clinical development programs and plans.
General and Administrative Expense
General and administrative expenses consist primarily of salaries and related benefits, including share-based compensation, related to our executive,
finance, legal and intellectual property, business development and support functions. Other general and administrative
104
expenses include allocated facility-related costs not otherwise included in research and development expenses, travel expenses and professional fees for
auditing, tax and legal services, including intellectual property and general legal services.
General and administrative expense for the year ended December 31, 2023 increased $7.6 million as compared to the year ended December 31, 2022,
primarily as a result of increases in consultancy expenses of $3.1 million, personnel related expenses including share-based compensation of $2.1 million
due to an increase in employee headcount, intellectual property and licenses expenses of $1.0 million, facilities and depreciation expense of $0.9 million,
legal expenses of $0.8 million and travel expenses of $0.5 million, partially offset by decreases in finance and human resources expenses of $0.9 million.
We expect general and administrative expenses to increase as we grow as a company, driven by the need to support a growing workforce, engaging in
financing transactions, establishing and maintaining our intellectual property rights, fulfilling our compliance requirements as a public company and related
legal, regulatory and potential commercialization costs.

Other income (loss), net consists of interest earned on our cash and cash equivalents held on account, accretion of investment earnings and net foreign
exchange gains or losses on our foreign denominated cash, cash equivalents, marketable securities, and payables and receivables. Other gains or losses
relate to the issuance and settlement of financial instruments. Other gains for the year ended December 31, 2023 decreased by $1.1 million as compared to
the year ended December 31, 2022 due to the reduction of gains associated with the derivative instrument recognized due to post-employment modification
of our settlement agreement with a former executive.

We are subject to income taxes in the Netherlands and the U.S. Our current and deferred tax provision represents taxable income attributed to our U.S.
operations as a consequence of allocating income to that jurisdiction. No current or deferred provision for income taxes has been made for income taxes in
the Netherlands due to losses for tax purposes. Further, given a history of losses in the Netherlands, no deferred tax assets in excess of deferred tax
liabilities are recognized as it is not more likely than not that they will be recovered.
The Tax Cuts and Jobs Act of 2017 (“TCJA”), which was signed into U.S. law in December 2017, eliminated the option to immediately deduct research
and development expenditures in the year incurred under Section 174 effective January 1, 2022. The amended provision under Section 174 required
companies to capitalize and amortize these expenditures over five years (for U.S.-based research). As of December 31, 2022, we recorded an increase to net
deferred tax assets of a $1.4 million and an increase to income taxes payable of a similar amount. During 2023, we concluded R&D expenses incurred by
the Merus US entity are not USA R&D costs but rather pass through R&D costs to Merus N.V and therefore not subject to Section 174 rules. The change
in our Section 174 position represents a change in estimate. The change in our Section 174 position as of year end 2023 from year end 2022 is based upon
this new information and does not reflect the misapplication of any information which was available at the previous financial statement reporting date.
During 2023, we removed the research and development costs deferred tax asset.
105
Income tax expense increased primarily due to an increase in book income before tax and a decrease in temporary differences due to the change in estimate
related to the treatment of Section 174 expenses in 2023.
Net Loss
Net loss for the year ended December 31, 2023 was $154.9 million, compared to $131.2 million for the year ended December 31, 2022. The change in net
loss of $23.7 million was primarily due to the increases general and administrative expenses and decreases in other income, partially offset by increases in
collaboration revenue and decreases in research and development expenses.
Liquidity and Capital Resources
Cash requirements
We require external sources of financing to fund our operations. Since inception through December 31, 2023, we have raised an aggregate of $1,158.7
million, of which $165.4 million was non-equity funding through our collaboration agreements, $882.6 million was from the sale of common shares and
$110.7 million was from private funding sources prior to our initial public offering. These amounts include aggregate immediate proceeds from the closing
of the collaboration and license agreement and share purchase agreement with Eli Lilly in January 2021 of $60.0 million, the aggregate net proceeds from
the January 2021 follow-on offering of $129.7 million, the aggregate net proceeds from the November 2021 follow-on offering of $118.7 million, the
aggregate net proceeds during the year ended December 31, 2022 from the "at the market" offering program pursuant to an Open Market Sale Agreement
(the "Sales Agreement") with Jefferies LLC (Jefferies) of $57.5 million, the aggregate net proceeds from the May 2023 "at the market" offering program
pursuant to the Sales Agreement with Jefferies of $63.8 million, and the aggregate net proceeds from the August 2023 underwriting agreement (the
“Underwriting Agreement”) with Jefferies LLC, BofA Securities, Inc., Guggenheim Securities, LLC and William Blair & Company, L.L.C., as
representatives of the several underwriters named therein (collectively, the “Underwriters”), of $162.2 million. As of December 31, 2023, we had $411.7
million in cash, cash equivalents and marketable securities that are available to fund our current and future operations.
In May 2021, we entered into the Sales Agreement with Jefferies, to sell from time to time up to $125.0 million of our common shares through an "at the
market" offering program under which Jefferies acts as the sales agent. During the year ended December 31, 2021, we did not sell any shares under the
Sales Agreement. During the year ended December 31, 2022, we had $59.5 million of gross proceeds from sales of our shares under the Sales Agreement.
During the year ended December 31, 2023, we had $65.5 million of gross proceeds from sales of our ordinary shares under the Sales Agreement. Having
sold approximately $124.9 million of the $125.0 million available under the Sales Agreement, on May 22, 2023, we delivered written notice to Jefferies,
effective as of such date, to terminate the Sales Agreement. We are not subject to any termination penalties related to the termination of the Sales
Agreement.
On August 9, 2023, we entered into an underwriting agreement (the “Underwriting Agreement”) with Jefferies, BofA Securities, Inc., Guggenheim
Securities, LLC and William Blair & Company, L.L.C., as representatives of the several underwriters named therein (collectively, the “Underwriters”), in
connection with the issuance and sale by us in a public offering of 6,818,182 common shares of the Company, nominal value €0.09 per share, at a public
offering price of $22.00 per share, less underwriting discounts and commissions, pursuant to an effective shelf registration statement on Form S-3 and
accompanying prospectus (Registration No. 333-255903), which became effective upon filing on May 7, 2021, and a prospectus supplement thereunder.
Under the terms of the Underwriting Agreement, we also granted the Underwriters an option exercisable for 30 days to purchase up to an additional
1,022,727 common shares at the public offering price, less underwriting discounts and commissions. On August 10, 2023, the Underwriters exercised this
option in full. The offering closed on August 14, 2023, and we received net proceeds of $162.2 million, after deducting underwriting discounts and fees.
In addition to our existing cash, cash equivalents and marketable securities, we may receive research and development co-funding and are eligible to earn a
significant amount of milestone payments under our collaboration agreements. Our ability to earn these payments and the timing of earning these payments
is dependent upon the outcome of our research and development activities and is uncertain at this time. Our collaboration and license agreements may
require payment of milestones to third parties contingent on future events.
Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity or debt
financings, collaboration arrangements, licensing, other business development opportunities and government grants. Except for any obligations of our
collaborators to make license, milestone or royalty payments under our agreements with them, and government grants, we do not have any committed
external sources of liquidity.
To the extent that we raise additional capital through the future sale of equity or debt, the ownership interest of our shareholders may be diluted, and the
terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing common shareholders. Debt financing
and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such
as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaboration arrangements, licensing
or other business development opportunities in the future, we may have to relinquish valuable rights to our technologies or intellectual property, future
revenue streams or product candidates or grant licenses on terms that may not be favorable to us.
106
If we are unable to raise any additional funds that may be needed through equity or debt financings when needed, we may be required to delay, limit,
reduce or terminate our product candidate 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 primary uses of capital are: clinical trial costs, third-party research and development services, personnel, laboratory and related supplies, legal,
intellectual property and other regulatory expenses and general overhead costs. Because our product candidates are in various stages of clinical and pre-
clinical development and the outcome of these efforts is uncertain, we cannot estimate the actual amounts necessary to successfully complete the
development and commercialization of our product candidates or whether, or when, we may achieve profitability. In addition, our expenditures as reported
in our financial statements may be expected to be variable due to that uncertainty. We enter into contracts in the normal course of business with CROs for
clinical and pre-clinical research studies, external manufacturers for product candidates for use in our clinical trials, and other research supplies and other
services as part of our operations. These contracts generally provide for termination on notice, and therefore are cancelable contracts and are not contractual
obligations. Our material contractual obligations, if any, are described elsewhere in this Annual Report on Form 10-K, including Notes 9 and 10 of the
attached Consolidated Financial Statements.
Based on our current operating plan, research and development plans and our timing expectations related to the progress of our programs, we expect that
our existing cash, cash equivalents and marketable securities as of December 31, 2023, will be sufficient to fund our planned operating expenses and capital
expenditure requirements into 2027. We have based this estimate on assumptions that may prove to be wrong, particularly as the process of testing product
candidates in clinical trials is costly and the timing of progress in these trials is uncertain. As a result, we could use our capital resources sooner than we
expect.

Operating Activities
Net cash used in operating activities for the year ended December 31, 2023 decreased $7.7 million as compared to the year ended December 31, 2022
primarily as a result of an increases in cash inflows from Other income of $7.8 million, and increase in operating cash receipts related to collaboration
arrangements (upfront payments, milestones, and research and development reimbursements) of $0.5 million, partially offset by increases in cash outflows
related to operating expenses of $0.6 million.
Investing Activities
Net cash used in investing activities during the year ended December 31, 2023 increased by $29.8 million as compared to the year ended December 31,
2022, primarily due to increases in purchases of marketable securities of $15.5 million and decreases in proceeds from maturities of marketable securities
of $17.9 million due to timing differences due to the make-up of the portfolio, partially offset by decreases in purchases of property and equipment of $3.6
million.
Financing Activities
Net cash provided by financing activities during the year ended December 31, 2023 increased by $171.3 million as compared to the year ended December
31, 2022, primarily due to higher proceeds received from the issuance of common shares under the August 2023 Underwriting Agreement of $162.2
million and the May 2023 Sales Agreement with Jefferies of $63.8 million compared to the 2022 proceeds received from the issuance of common shares
under the Sales Agreement with Jefferies of $57.7 million, less $0.2 million increase in payments for offering costs, and increases in proceeds from stock
option exercises of $3.4 million.
107
Cash Management
Our objective in managing our cash resources (cash, cash equivalents, and marketable securities) is to safeguard Merus’ ability to continue as a going
concern and to minimize the cost of capital to provide returns for shareholders and benefits for other stakeholders.
Once we receive a source of financing, our cash resources are invested to preserve capital as a primary goal, and to derive some return as a secondary
consideration. Cash and cash equivalents include deposits and investments held with financial institutions with an original maturity date of less than three
months. Marketable securities include commercial paper, securities issued by several public corporations and the U.S. Treasury with a maturity date of
greater than three months at the date of settlement. Cash and cash equivalents are held at banks and financial institutions with credit ratings varying
between A and AAA, while investments are in highly rated vehicles with similar credit ratings.
Our invested cash resources are deployed to achieve our operating objectives in furthering our programs.
Critical Accounting Policies and Estimates
Our accounting policies are more fully described in Note 2 to our Consolidated Financial Statements included elsewhere in the Annual Report on Form 10-
K. As disclosed in Note 2, the preparation of financial statements in conformity with generally accepted accounting principles requires management to
make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Actual results
could differ significantly from those estimates. We believe that the following discussion addresses our most critical accounting policies and estimates,
which are those that are most important to the portrayal of our financial condition and results of operations and require management’s most difficult,
subjective and complex judgments on material matters.
Revenue Recognition
Significant judgment is required in applying our accounting policies concerning revenue recognition. Our collaboration arrangements may be subject to the
scope of many accounting standards in addition to the standards applicable to revenue from contracts with customers, including whether all or part of the
arrangement may be a collaboration arrangement as defined in the accounting standards or whether financial instruments exchanged in the same
arrangement may be subject to other guidance. Such matters may impact the initial recognition, subsequent accounting and disclosures concerning the
arrangement.
Our collaboration arrangements typically include a license to our intellectual property and significant judgment is applied in determining whether the
particular license is distinct from other performance obligations in the arrangement. We consider whether the counterparty may be able to utilize the license
in the absence of the provision of other performance obligations by us. Each collaboration features unique terms to a license and the provision of other
performance obligations also varies. Such considerations impact the timing of recognition of consideration allocated to performance obligations.
A key judgment in the application of our revenue recognition policy concerns the method of recognition of revenue over time as performance obligations
are completed. Methods may include an input-based, output-based or other rational allocation method. Furthermore, estimates of progress towards
satisfaction of performance obligations are often derived from expectations on the outcome of research and development activities which are subject to
uncertainty.
Changes in these estimates impact the timing of revenue recognition. These estimates have not materially changed in the current period presented in our
Consolidated Financial Statements. For example, with respect to the license and related activities performance obligation of the Incyte collaboration
arrangement recognized as revenue over time as access to the platform for the generation of potential product candidates is provided to the customer, an
increase of one year in the estimate as of January 1, 2023 would have decreased revenue recognized for the year ended December 31, 2023 by
approximately $4.2 million, excluding the effects of foreign exchange translation.
Going Concern
Our evaluation of our ability to continue as a going concern requires us to evaluate our future sources and uses of cash sufficient to fund our currently
expected operations in conducting research and development activities one year from the date our financial statements are issued. We evaluate the
probability associated with each source and use of cash resources in making our going concern determination. The research and development of
pharmaceutical products is inherently subject to uncertainty.
Recent Accounting Pronouncements
For a discussion of pending and recently adopted accounting pronouncements, see Note 2 to our Consolidated Financial Statements included elsewhere in
this Annual Report on Form 10-K.
108
Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
We are exposed to market risk from changes in interest rates, foreign exchange rates and inflation. All of these market risks arise in the ordinary course of
business, as we do not engage in speculative trading activities. The following analysis provides additional information regarding these risks.
Interest Rate Risk
Our investments in marketable securities, which consist of corporate paper and notes, U.S. government securities and treasury notes, are subject to interest
rate risk. As of December 31, 2023, marketable securities were $207.4 million. As of December 31, 2022, marketable securities were $178.9 million. Due
to the conservative and short-term nature of these investments in our portfolio, an immediate 10% change in market interest rates would not have a material
impact on the fair market value of our investment portfolio or on our financial position or results of operations for either year. We had no outstanding debt
that is subject to interest rate risk as of December 31, 2023 or December 31, 2022.
Foreign Currency and Exchange Risk
Merus US, Inc.’s functional currency is the U.S. dollar. The functional currency of Merus N.V. is the euro. Our revenues and monetary assets and liabilities
are mainly denominated in U.S. dollars. A significant portion of our operating costs are in the Netherlands, which are denominated in the euro. This foreign
currency exposure gives rise to market risk associated with exchange rate movements of the U.S. dollar against the euro. Furthermore, we anticipate that a
significant portion of our expenses will continue to be denominated in the euro. A hypothetical 15% weakening of the U.S. dollar compared to the euro
would have increased our net loss for the year ended December 31, 2023, by approximately $24.5 million and increased our currency translation
adjustment by approximately $66.1 million. A hypothetical 15% strengthening of the U.S. dollar compared to the euro would have an equal and opposite
effect on our financial statements. A hypothetical 15% weakening of the U.S. dollar compared to the euro would have increased our net loss for the year
ended December 31, 2022, by approximately $20.0 million and increased our currency translation adjustment by approximately $3.4 million. A
hypothetical 15% strengthening of the U.S. dollar compared to the euro would have an equal and opposite effect on our financial statements.
Impact of Inflation
While it is difficult to accurately measure the impact of inflation due to the imprecise nature of the estimates required, we do not believe inflation has had a
material effect on our historical results of operations and financial condition. However, if our costs were to become subject to significant inflationary
pressures, we may not be able to fully offset higher costs through raising funds or other corrective measures, and our inability or failure to do so could
adversely affect our business, financial condition, and results of operations.
Item 8. Financial Statements and Supplementary Data.
The financial statements required to be filed pursuant to this Item 8 are included in this Annual Report on Form 10-K. An index of those financial
statements is found in Item 15 of Part IV of this Annual Report on Form 10-K.
Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None.
Item 9A. Controls and Procedures
Limitations on Effectiveness of Controls and Procedures
In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed
and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and
procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible
controls and procedures relative to their costs.
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our principal executive and financial officer, has evaluated, as of the end of the period covered by this Annual
Report on Form 10-K, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act).
Based on such evaluation, our principal executive and principal financial officer concluded that our disclosure controls and procedures were effective at the
reasonable assurance level as of December 31, 2023.
109
Management’s Annual Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over our financial reporting, as such term is defined in Rule 13a-
15(f) under the Exchange Act. Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the
criteria set forth in “Internal Control - Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Based on this assessment, our management concluded that, as of December 31, 2023, our internal control over financial reporting was effective.
The effectiveness of our internal control over financial reporting as of December 31, 2023 has been audited by KPMG Accountants N.V., an independent
registered public accounting firm, as stated in their report, which is included in this Annual Report on Form 10-K in Part IV, Item 15.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) identified in
management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2023 that
materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Item 9B. Other Information.
(b) Insider Trading Arrangements and Policies
During the three months ended December 31, 2023, no director or "officer" (as defined in Rule 16a-1(f) under the Exchange Act) of the Company adopted
or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.
Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections.
Not applicable.

Report of Independent Registered Public Accounting Firm
To the Stockholders and Board of Directors
Merus N.V.:
Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting
We have audited the accompanying consolidated balance sheets of Merus N.V. and subsidiary (the Company) as of December 31, 2023 and 2022, the
related consolidated statements of operations and comprehensive loss, cash flows, and stockholders’ equity, for each of the years in the three-year period
ended December 31, 2023, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control
over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission.
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of
December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023, in
conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal
control over financial reporting as of December 31, 2023 based on criteria established in Internal Control – Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission.
Basis for Opinions
The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting,
and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on
Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion
on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company
Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable
assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective
internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements 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.
Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that
a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also
included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our
opinions.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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 the policies or procedures may deteriorate.
F-2
Critical Audit Matters
Critical audit matters are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be
communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2)
involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

MERUS N.V.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. The Company
Merus N.V. is a clinical-stage oncology company developing innovative antibody therapeutics, headquartered in Utrecht, the Netherlands. Merus US, Inc.
is a wholly-owned subsidiary of Merus N.V. located at 139 Main Street, Cambridge, Massachusetts, United States (collectively, the “Company”).
Since inception, the Company has generated an accumulated deficit of $753.1 million as of December 31, 2023. The Company expects to continue to incur
significant expenses and operating losses for the foreseeable future as its antibody candidates advance through discovery, pre-clinical development and
clinical trials and as it seeks regulatory approval and pursues commercialization of any approved antibody candidate.
As a result, the Company may need additional financing to support its continuing operations. Until the Company can generate significant revenue from
product sales, if ever, the Company expects to finance its operations through public equity offerings, debt financings, or other sources, which may include
collaborations, business development and licensing opportunities with third parties. Adequate additional financing may not be available to the Company on
acceptable terms, or at all. The Company’s inability to raise capital as and when needed would have a negative impact on its financial condition and ability
to pursue its business strategy. The Company will need to generate significant revenues to achieve profitability and may never do so.
2. Summary of Significant Accounting Policies
Basis of Preparation
The Company prepared its consolidated financial statements in compliance with generally accepted accounting principles in the U.S. ("U.S. GAAP"). Any
reference in these notes to applicable guidance is meant to refer to authoritative U.S. GAAP as found in the Accounting Standards Codification ("ASC")
and Accounting Standards Update ("ASU") of the Financial Accounting Standards Board ("FASB").
Principles of Consolidation
Subsidiaries are entities controlled by the Company, consisting of Merus N.V.’s wholly owned subsidiary Merus US, Inc. The Company controls an entity
when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over
the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the
date on which control ceases. All significant intercompany balances and transactions have been eliminated in consolidation.
Functional and Presentation Currency
Items recorded in each of the Company’s entities are measured using the currency of the primary economic environment in which the entity operates (the
"functional currency"). Merus US, Inc.’s functional currency is the U.S. dollar. The functional currency of Merus N.V. is the euro. After measuring foreign
currency denominated transactions into an entity’s functional currency, to the extent that a subsidiary’s functional currency differs from its parent, a
subsidiary’s financial position and results of operations are translated into its parent’s functional currency. The Company’s consolidated financial position
and results of operations are translated into the U.S. dollar as the Company’s reporting currency.
Use of Estimates
The preparation of these consolidated financial statements in accordance with U.S. GAAP requires management to make estimates, judgments and
assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities, as of the date of the consolidated
financial statements, and the reported amounts of collaboration revenue and expenses during the reporting period. Actual results and outcomes may differ
materially from management’s estimates, judgments and assumptions.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk include cash, cash equivalents, marketable securities and
accounts receivable. The Company attempts to minimize the risks related to cash, cash equivalents and marketable securities by working with highly rated
financial institutions that invest in a broad and diverse range of financial instruments as defined by the Company. The Company has established guidelines
relative to credit ratings and maturities intended to safeguard principal balances and maintain liquidity. The Company maintains its funds in accordance
with its investment policy, which defines allowable investments, specifies credit quality standards and is designed to limit the Company’s credit exposure to
any single issuer.
F-8
Accounts receivable represent amounts due from collaboration partners. The Company monitors economic conditions to identify facts or circumstances that
may indicate that any of its accounts receivable are at risk of collection.
Subsequent Events
The Company considers events or transactions that occur after the balance sheet date but before the consolidated financial statements are issued to provide
additional evidence relative to certain estimates or to identify matters that require additional disclosure. The Company evaluated all events and transactions
through the date these financial statements were filed with the Securities and Exchange Commission.
Fair Value Measurements
Fair value is defined as an exit price, representing the amount that would be received upon the sale of an asset or payment to transfer a liability in an
orderly transaction between market participants. Fair value is a market-based measurement that is determined based on assumptions that market
participants would use in pricing an asset or liability. A three-tier fair value hierarchy is used to prioritize the inputs in measuring fair value as follows:
•
•
•
Level 1 – Quoted market prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access
at the measurement date.
Level 2 – Quoted market prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in
markets that are not active, or other inputs that are observable, either directly or indirectly. Fair value determined through the use of models or
other valuation methodologies.
Level 3 – Significant unobservable inputs for assets or liabilities that cannot be corroborated by market data. Fair value is determined by the
reporting entity’s own assumptions utilizing the best information available and includes situations where there is little market activity for the
asset or liability.
The asset’s or liability’s fair value measurement within the fair value hierarchy is based upon the lowest level of any input that is significant to the fair
value measurement.
The Company considers its cash, cash equivalents, accounts receivable, marketable securities due with maturities 12 months or less, and accounts payable
financial instruments to reflect their fair value given their short maturity and risk profile of the counterparty.
Going Concern
At each reporting period, the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue
as a going concern within one year after the date that the financial statements are issued. The Company is required to make certain additional disclosures if
it concludes substantial doubt exists and it is not alleviated by the Company’s plans or when its plans alleviate substantial doubt about the Company’s
ability to continue as a going concern.
The Company’s evaluation entails analyzing prospective operating budgets and forecasts for expectations of the Company’s cash needs, and comparing
those needs to the current cash, cash equivalent and marketable security balances. After considering the Company’s current research and development plans
and the timing expectations related to the progress of its clinical-stage programs and its plans to pursue commercialization of any antibody candidate, if
approved, and after considering its existing cash, cash equivalents and marketable securities as of December 31, 2023, the Company did not identify
conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year from the date these financial
statements were issued. Additional details of the Company’s cash runway are described in Note 1 The Company.
Cash and Cash Equivalents
The Company considers all highly liquid debt securities with original final maturities of three months or less from the date of purchase to be cash
equivalents. Instruments subject to restrictions are not included in cash and cash equivalents.
Restricted Cash
The Company maintains certain cash balances restricted to withdrawal or use. Restricted cash includes cash held as collateral for certain contractual
agreements and is recorded in other assets in the consolidated balance sheets.
F-9
Marketable Securities
The Company classifies marketable securities that are debt securities with a remaining maturity when purchased of greater than three months as held-to-
maturity as the Company has the positive intent and ability to hold such debt securities through maturity.
Debt securities that are classified as held-to-maturity are initially recognized and measured at fair value. Subsequent to initial recognition, they are
measured at amortized cost using the effective interest rate method. Interest income from these debt securities is included in interest income. Marketable
securities are classified as current if their expected maturity is within one year or less of the balance sheet date and non-current if their maturity is beyond
one year of the balance sheet date.
Accounts Receivable
Accounts receivable are amounts due from collaboration partners as a result of research and development services provided or milestones achieved but not
yet paid.
Allowance for Credit Losses
The Company evaluates its cash equivalents, accounts receivable and held-to-maturity marketable securities financial assets for expected credit losses.
Expected credit losses represent the portion of the amortized cost basis of a financial asset that an entity does not expect to collect. An allowance for
expected credit losses is meant to reflect a risk of loss even if remote, irrespective of the expectation of collection from a particular issuer or debt security.
The Company has not historically experienced any credit losses on any of its financial assets.
With respect to cash equivalents and accounts receivable, given consideration of their short maturity, lack of historical losses and the current environment,
the Company concluded there is generally no expected credit losses for these financial assets. With respect to held-to-maturity marketable securities which
are comprised of debt securities, the Company evaluates expected credit losses on a pooled basis based on issuer-type which have similar credit risk
characteristics. The allowance for credit losses is immaterial for all periods presented.
Property and Equipment
The Company records property and equipment at cost. The Company calculates depreciation and amortization using the straight-line method over the
following estimated useful lives:
Asset Category
Laboratory equipment
Office furniture and equipment
Leasehold improvements
Useful Lives
5 years
5 years
Shorter of term of lease or 10 years
The Company capitalizes expenditures for new property and equipment and improvements to existing facilities and charges the cost of maintenance to
expense. The Company eliminates the cost of property retired or otherwise disposed of, along with the corresponding accumulated depreciation or
amortization, from the related accounts, and the resulting gain or loss is reflected in the results of operations.
Intangible Assets
Intangible assets are identifiable non-monetary assets without physical substance. An asset is a resource that is controlled by the enterprise as a result of
past events (for example, purchase or self-creation) and from which future economic benefits (inflows of cash or other assets) are expected. The useful
lives of intangible assets are assessed to be definite-lived and amortized over the useful economic life. The Company’s intangible assets are comprised of
purchased licenses to intellectual property and software licenses.
Impairment of Long-Lived Assets
The Company reviews long-lived assets to be held and used, including property and equipment, operating lease right-of-use assets and definite-lived
intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be
recoverable.
Evaluation of recoverability is first based on an estimate of undiscounted future cash flows resulting from the use of the asset or asset group and its
eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the asset or asset group, the assets
are written down to their estimated fair values. No such impairments were recorded in 2023, 2022 or 2021.
F-10
Leases
The Company determines if an arrangement is or contains a lease at inception. For leases with a term of 12 months or less, the Company does not recognize
a right-of-use asset or lease liability. The Company does not have any finance leases.
Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to
make lease payments arising from the lease, and excludes non-lease payments. Operating lease right-of-use assets and liabilities are recognized at the lease
commencement date based on the present value of lease payments over the lease term. As the Company’s leases typically do not provide an implicit rate,
the Company uses an estimate of its incremental borrowing rate based on the information available at the lease commencement date in determining the
present value of lease payments.
Operating lease right-of-use assets also include the effect of any lease payments made and excludes lease incentives. The lease terms may include options
to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a
straight-line basis over the lease term.
The Company has real estate operating lease agreements with lease and non-lease components, which are generally accounted for separately as operating
lease costs and variable lease costs. Non-lease components in real estate leases refer to services provided by the lessor related to the premises. Fixed and
variable lease payments are both allocated to lease and non-lease components. The allocation is determined on a relative fair value basis of the services
provided relative to the operating lease of premises. With respect to equipment leases, the Company has elected not to allocate payments amongst lease and
non-lease components as a practical expedient as afforded under ASC 842, Leases.
Income Taxes
Deferred Taxes
The Company records deferred taxes to recognize the future effects of temporary differences between the tax basis and financial statement carrying amount
of assets and liabilities. The Company measures the deferred taxes using enacted tax rates expected to apply when the temporary differences are realized
and records a valuation allowance to reduce deferred tax assets if it is determined that it is more likely than not that all or a portion of the deferred tax asset
will not be realized. The Company considers many factors when assessing the likelihood of future realization of deferred tax assets, including recent
earnings results, expectations of future taxable income, carryforward periods available, reversing taxable temporary differences and other relevant factors.
The Company records changes in the required valuation allowance in the period that the determination is made.
Unrecognized Tax Benefits
The Company assesses its income tax positions and records tax benefits for all years subject to examination based upon management’s evaluation of the
technical merits, facts, circumstances and information available as of the reporting date. For those tax positions where it is more likely than not that a tax
benefit will be sustained, the Company records the largest amount of tax benefit with a greater than 50.0% likelihood of being realized upon settlement
with a taxing authority having full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax
benefit will be sustained, the Company does not recognize a tax benefit in the financial statements. The Company records interest and penalties related to
an underpayment of income taxes, if applicable, as a component of income tax expense.
Revenue Recognition
The Company 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 an arrangement, the Company performs the
following five step analysis:
i.
ii.
identify the contract(s) with a customer;
identify the performance obligations in the contract;
iii. determine the transaction price;
iv.
v.
allocate the transaction price to the performance obligations in the contract; and
recognize revenue when (or as) the entity satisfies a performance obligation.
The Company has entered into collaboration and license agreements, which are within the scope of ASC 606, Revenue from Contracts with Customers, to
discover, develop, manufacture and commercialize product candidates. The terms of these agreements typically contain multiple promises or obligations,
which may include: (i) licenses, or options to obtain licenses, to product candidates or future product candidates directed to specific targets (referred to as
“exclusive licenses”) and (ii) research and development activities to be
F-11
performed on behalf of the collaboration partner related to the licensed targets. The Company also derives revenue from government grants.
As part of the accounting for these arrangements, the Company must use judgment to determine:
a)
b)
c)
the number of performance obligations based on the determination under step (ii) above and whether those performance obligations are distinct
from other performance obligations in the contract;
the transaction price under step (iii) above;
the stand-alone selling price for each performance obligation identified in the contract for the allocation of transaction price in step (iv) above;
d) whether the combined performance obligation is satisfied over time or at a point in time in step (v) above; and
e)
the appropriate method for measuring progress toward complete satisfaction of a performance obligation in step (v) above.
The Company uses judgment to determine whether milestones or other variable consideration, except for sales-based royalties, should be included in the
transaction price as described further below. The transaction price is allocated to each performance obligation on a relative stand-alone selling price basis,
for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. The Company recognizes variable
consideration when the constraint has been resolved. Based on the nature of the variable consideration related to milestones, the Company allocates the
variable amount (and subsequent changes to that amount) entirely to a performance obligation or to a distinct good or service that forms a part of a single
performance obligation. In validating its estimated stand-alone selling price, the Company evaluates whether changes in the key assumptions used to
determine its estimated stand-alone selling price will have a significant effect on the allocation of arrangement consideration between performance
obligations.
Amounts received prior to revenue recognition are recorded as deferred revenue. Amounts expected to be recognized as revenue within the 12 months
following the balance sheet date are classified as current portion of deferred revenue in the accompanying consolidated balance sheets. Amounts not
expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion.
Amounts recognized as revenue, but not yet received or invoiced are generally recognized as unbilled receivables.
Exclusive Licenses
If the license to the Company’s intellectual property is determined to be distinct from the other promises or performance obligations identified in the
arrangement, which generally include research and development services, 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.
In assessing whether a license is distinct from the other promises, the Company considers relevant facts and circumstances of each arrangement, including
the rights and obligations set out in the contract, the research and development capabilities of the collaboration partner and the availability of the associated
expertise in the general marketplace. In addition, the Company considers whether the collaboration partner can benefit from the license for its intended
purpose without the receipt of the remaining promises, whether the value of the license 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.
For licenses that are combined with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to
determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring
progress for purposes of recognizing revenue.
The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue
recognition. 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.
F-12
The Company’s arrangements may provide the collaboration partner with the right to select a target for licensing either at the inception of the arrangement
or in the future. Under these arrangements, fees may be due to the Company (i) at the inception of the arrangement as an upfront fee or payment, (ii) upon
the exercise of an option to acquire a license or (iii) upon extending the selection period as an extension fee or payment. If an arrangement is determined to
contain customer options that allow the customer to acquire additional goods or services, the goods and services underlying the customer options are not
considered to be performance obligations at the outset of the arrangement, as they are contingent upon option exercise. The Company evaluates the
customer options for material rights, or options to acquire additional goods or services for free or at a discount. If the customer options are determined to
represent a material right, the material right is recognized as a separate performance obligation at the inception of the arrangement. The Company allocates
the transaction price to material rights based on the relative stand-alone 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.
For arrangements that include sales-based milestones and royalties, and the license is deemed to be the predominant item to which the royalties relate, the
Company recognizes revenue at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has
been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any sales-based milestones or royalty revenue resulting
from any of its arrangements.
Research and Development Services
The promises under the Company’s collaboration and license agreements generally include research and development services to be performed by the
Company on behalf of the collaboration partner. For performance obligations that include research and development services, the Company recognizes
revenue allocated to such performance obligations based on an appropriate measure of progress. The Company utilizes judgment to determine the
appropriate method of measuring progress for purposes of recognizing revenue, which is generally an input measure such as costs incurred. The Company
evaluates the measure of progress each reporting period as described under Exclusive Licenses above.
Reimbursements from the partner are evaluated as to whether the Company acts as a principal or an agent in such relationships. The Company evaluates
whether control over the underlying goods or services were obtained prior to transferring these goods or services to the collaboration partner. Where the
Company does not control the goods or services prior to transferring these goods or services to the collaboration partner, such reimbursements are
presented net of costs.
At the inception of each arrangement that includes development milestone payments in respect of development efforts, the Company evaluates whether the
development milestones are considered probable of being achieved and estimates the amount to be included in the transaction price using the most likely
amount method. If it is probable that a significant revenue reversal would not occur, the associated development milestone value is included in the
transaction price. Development milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not
considered probable of being achieved until those approvals are received. The Company evaluates factors such as the scientific, clinical, regulatory,
commercial, and other risks that must be overcome to achieve the particular development milestone in making this assessment. There is judgment involved
in determining whether it is probable that a significant revenue reversal would not occur.
At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of all development milestones subject to
constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which
would affect revenues and earnings in the period of adjustment. If a milestone or other variable consideration relates specifically to the Company’s efforts
to satisfy a single performance obligation or to a specific outcome from satisfying the performance obligation, the Company generally allocates the
milestone amount entirely to that performance obligation once it is probable that a significant revenue reversal would not occur.
Government Grants
The Company receives certain government and regional grants, which support its research efforts in defined projects, and include contributions towards the
R&D cost. When there is reasonable assurance that the Company will comply with the conditions attached to a received grant, and when there is reasonable
assurance that the grant will be received, government grants are recognized as revenue on a gross basis in the consolidated statement of profit or loss and
comprehensive loss on a systematic basis over the periods in which the Company recognizes expenses for the related costs for which the grants are
intended to compensate. In the case of grants related to assets, the received grant will be deducted from the carrying amount of the asset. Government grant
revenue may be subject to review by a government authority in periods subsequent to their recognition and may result in the reversal of grant revenue
previously recognized. Reversals of grant revenue are presented as contra revenue in the consolidated statement of operations.
F-13
Research and Development Expenses
Research and development expenses are expensed as incurred. Research and development expenses are comprised of costs incurred in providing research
and development activities, including salaries and benefits, facilities costs, overhead costs, contract research and development services, and other outside
costs. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the
activity has been performed or when the goods have been received rather than when the payment is made.
When third-party service providers’ billing terms do not coincide with the Company’s period-end, the Company is required to make estimates of its
obligations to those third parties, including clinical trial and pharmaceutical development costs, contractual services costs and costs for supply of its
product candidates incurred in a given accounting period and record accruals at the end of the period. The Company bases its estimates on its knowledge of
the research and development programs, services performed for the period, past history in conducting similar activities and the expected duration of the
third-party service contract, among other considerations.
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 vendors will exceed the level of services provided and result in a prepayment of research and development expenses.
The WBSO (afdrachtvermindering speur- en ontwikkelingswerk) is a Dutch fiscal facility that provides subsidies to companies, knowledge centers and
self-employed people who perform research and development activities (as defined in the WBSO Act). Under this act, a contribution is paid towards the
labor costs of employees directly involved in research and development. For the years ended December 31, 2023, 2022 and 2021, the Company recognized
$6.3 million, $5.9 million and $9.3 million as a reduction of research and development expenses, respectively.
Share-Based Compensation
The Company measures employee share-based compensation based on the grant date fair value of the share-based compensation award. The Company
grants stock options at exercise prices equal to the fair value of the Company’s common stock on the date of grant, based on observable market prices.
For share-based awards subject time-based vesting, the Company recognizes employee share-based compensation expense on a straight-line basis over the
requisite service period of the awards, generally from the date of grant through each vesting date. The Company recognizes forfeitures at the time they
occur. The actual expense recognized over the vesting period will only represent those options that vest; the effect of forfeitures in the recognition of
periodic compensation expense are not estimated prior to their occurrence.
Earnings (Loss) per Share
The Company computes basic earnings (loss) per share by dividing income (loss) allocable to common stockholders by the weighted average number of
shares of common stock outstanding. During periods of income, the Company allocates participating securities a proportional share of income determined
by dividing total weighted average participating securities by the sum of the total weighted average common shares and participating securities. During
periods of loss, the Company allocates no loss to participating securities because they have no contractual obligation to share in the losses of the Company.
The Company computes diluted earnings (loss) per share after giving consideration to the dilutive effect of stock options and restricted stock units (“RSU”)
that are outstanding during the period, except where such non-participating securities would be anti-dilutive.
Segment Information
The Company operates in one reportable segment, which comprises the discovery and development of innovative therapeutics.
Recently Adopted Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the FASB or other standard‑setting bodies that are adopted by the Company as of the
specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not
have a material impact on its financial position or results of operations upon adoption.
In August 2018, the FASB issued ASU No. 2018-2, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-
Duration Contracts, which is aimed at improving the Codification related to long-duration contracts which will improve the timeliness of recognizing
changes in the liability for future policy benefits, simplify accounting for certain market-based options, simplify the amortization of deferred acquisition
costs, and improve the effectiveness of required disclosures. The FASB delayed the effective date of ASU 2018-12 to periods beginning after December 15,
2022, and interim periods within those fiscal years. This ASU is effective for the Company beginning January 1, 2023, and interim periods within that year.
The Company adopted
F-14
and applied the amendments of this ASU to its disclosures. The application of this ASU did not have a material impact on the Company's financial position,
results of operations or cash flows.
In October 2021, the FASB issued ASU 2021-08, Business Combination (Topic 805): Accounting for Contract Assets and Contract Liabilities from
Contracts with Customers. This guidance amends ASC 805 to “require acquiring entities to apply Topic 606 to recognize and measure contract assets and
contract liabilities in a business combination.” Under current GAAP, an acquirer generally recognizes such items at fair value on the acquisition date. This
ASU is effective for the Company beginning January 1, 2023, and interim periods within that year. The Company adopted and applied the amendments of
this ASU to its disclosures. The application of this ASU did not have a material impact on the Company's financial position, results of operations or cash
flows.
In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands
annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. ASU
2023-07 is effective for annual periods beginning December 15, 2023, and for interim periods beginning after December 15, 2024, with early adoption
permitted. The Company is currently evaluating the potential effect that the updated standard will have on its financial statement disclosures.

In 2020 and 2021, Dutch tax authorities enacted new tax rates applicable to future periods which impact the measurement of deferred income taxes. The
effect of the change in the valuation allowance each year reflects the increase or decrease in the valuation allowance against deferred tax assets attributable
to the Netherlands.
The components of the Company’s deferred tax assets (liabilities) consist of the following:
Deferred tax assets:
Net operating loss carryforwards
Deferred revenue
Research and development costs

After consideration of all positive and negative evidence, the Company believes that it is more-likely-than-not that our Netherlands deferred tax assets that
are not supported by reversing temporary differences will not be realized. As a result, the Company established a valuation allowance of $173.2 million and
$129.8 million as of December 31, 2023 and 2022, respectively. The increase in the valuation allowance of $43.3 million and $23.4 million for the years
ended December 31, 2023 and 2022, respectively, is primarily attributable to the increase in net operating loss carryforward deferred tax assets for which a
full valuation allowance applies. As of December 31, 2023, the portion of the valuation allowance for deferred tax assets for which subsequently
recognized tax benefits would be credited directly to contributed capital totaled $5.4 million.
As of December 31, 2023, the Company did not have any net operating losses for U.S. federal or state income tax purposes. The Company had net
operating loss carryforwards for Dutch income tax purposes of $628.0 million as of December 31, 2023. Under Dutch tax law, net operating loss
carryforwards may be used to offset future taxable income in full up to €1.0 million and 50% of taxable income that exceeds €1.0 million. Effective as of
January 1, 2022, these losses can be carried forward indefinitely.
As of December 31, 2023, the Company had no unrecognized tax benefits. As of December 31, 2023, the Company had no accrued interest or penalties
related to underpayments of income taxes and no amounts have been recognized in the consolidated statements of operations. The Company will recognize
interest and penalties related to an underpayment of income taxes in income tax expense.
F-18
The Company files income tax returns in the U.S. federal and Massachusetts jurisdictions as well as in the Netherlands. The statute of limitations for
assessment by the Internal Revenue Service (IRS), and Massachusetts tax authorities is closed for tax years prior to 2020. The statute of limitations for
assessment by the Netherlands tax authorities is closed for tax years prior to 2018. The Company is not currently under examination by the IRS or any
other jurisdictions for any tax years.
9. Operating Leases
The Company has noncancelable operating leases for offices and lab spaces expiring at various dates through 2032.
Merus N.V. has non-cancellable operating leases for its corporate headquarters in Utrecht, the Netherlands. In December 2022, the Company moved into its
new headquarters called the "Accelerator" in the Utrecht Science Park, at 17 Uppsalalaan, 3rd and 4th floor, 3583 CT, Utrecht.
On July 19, 2019, Merus N.V. entered into a lease agreement with Kadans Science Partner XIII B.V. (“Kadans”) for the Accelerator headquarters. In April
2022, the Accelerator lease between the Company and Kadans commenced. In accordance with the accounting requirements under ASC 842, the right-of-
use asset and lease obligation were not recorded until the lease commenced. In December 2022, the Company completed the fit-out construction on
approximately 4,957 square meters of office and laboratory space in the premises. The lease provides for a base rent of approximately €1.4 million per
annum. The rent amount is subject to adjustment based on the consumer price index (the “CPI”) annually, beginning one year after the lease
commencement date, subject to certain limitations if the CPI is greater than 3.0%. The initial term of the lease is ten years with two 5-year renewal options
following the initial term, unless earlier terminated by the Company or Kadans, except that the earliest Kadans may terminate the lease is 20 years from the
completion date of the premise construction. The Company expects the lease to end as of April 4, 2032. On April 5, 2022, the Company recognized a right-
of-use asset of $11.5 million, or €10.5 million, and a lease liability of $12.4 million, or €11.3 million, on the consolidated balance sheets. In connection
with signing the lease, the Company received a lease incentive of $0.9 million, or €0.8 million. To measure the lease liability at the commencement date,
the Company discounted the outstanding lease payments using an incremental borrowing rate of 4.85%. During the three months ended June 30, 2023, in
accordance with the terms of the lease agreement, the annual rent for the Accelerator lease increased due to increases in the consumer price index (CPI).
The portion of the rent payments related to the CPI index are included within variable lease costs. There have been no other changes in the Company’s
lease arrangements during the twelve months ended December 31, 2023.
During the year ended December 31, 2021, the Company signed a lease amendment (the “Amendment”), which extended the term of the lease for its
former corporate headquarters with Stichting Incubator Utrecht by approximately 1.5 years ending at the end of March 2023. The Amendment did not
include additional right-of-use other than the extended lease term. There is no additional renewal term included in the Amendment to consider in the
estimate of the lease term. On December 7, 2022, the Company signed a second lease amendment terminating the lease for the former corporate
headquarters as of January 1, 2023. The Company continued to make payments through mid-February 2023. The Company accounted for the second
amendment as a lease modification and reduced the lease liability and right-of-use asset by approximately $0.1 million to equal to the remaining lease
payments. The lease liability and right-of-use asset for the former corporate headquarters was reduced to $0 as the final payments were made during the
first quarter of 2023.
In March 2019, Merus US, Inc. entered into a non-cancellable operating lease agreement for office space in Cambridge, Massachusetts. The lease
commenced in the second quarter of 2019 and has a term of seven years, and may be extended for another five years. Given the Company’s current plans,
the renewal term has not been included in the estimate of the lease term. Fixed lease payments increase annually and include an increase on an inflationary
measure. Variable payments include amounts due to the lessor for additional services and cost reimbursements.
The components of lease cost recorded in the Company’s consolidated statement of operations and statement of cash flows were as follows:
Operating lease cost
Variable lease cost
Total lease cost included in operating expenses
Cash paid to lessors included in operating cash outflows

10. Commitments and Contingencies
Indemnities
The Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s
request in such capacity. The maximum potential amount of future payments the Company could be required to make is unlimited; however, the Company
has directors’ and officers’ insurance coverage that is intended to limit its exposure and enable it to recover a portion of any future amounts paid.
The Company enters into certain agreements with other parties in the ordinary course of business that contain indemnification provisions. These typically
include agreements with directors and officers, business partners, contractors, landlords, clinical sites and customers. Under these provisions, the Company
may indemnify and hold harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities,
such as gross negligence, willful misconduct or at times, other activities. These indemnification provisions may survive termination of the underlying
agreements. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions may be
unlimited. However, to date the Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As
a result, the estimated fair value of these obligations is minimal. Accordingly, the Company did not have any liabilities recorded for these obligations as of
December 31, 2023.
Litigation
From time to time, the Company may be involved in various claims and legal proceedings relating to or arising out of the Company’s operations. The
Company is not currently a party to any material legal proceedings.
On August 19, 2022, Kymab Limited ("Kymab"), a subsidiary of Sanofi, filed a notice of opposition against the Company's EP3456190 patent (the "'190
patent"), entitled "Antibody Producing Transgenic Murine Animal," in the European Opposition Division of the European Patent Office (the "EPO"). The
notice asserted, as applicable, the '190 patent is contrary to the provision of Article 123(2) EPC, Article 75(1) EPC and Article 100(c) EPC, and alleges the
'190 patent lacks novelty and/or is obvious contrary to the provisions of Articles 54 and/or 56 EPC, and Article 100(a) EPC, and that the specification of
the '190 patent does not provide sufficient disclosure of the subject matter of the inventions contravening Article 83 EPC and Article 100(b). On January
17, 2023, the Company timely filed a response before the European Opposition Division of the EPO contesting each of these assertions, with further oral
proceedings scheduled to follow on January 18, 2024. On June 2, 2023, the European Opposition Division issued a non-binding preliminary decision. On
January 18, 2024, the European Opposition Division held oral proceedings addressing each allegation of invalidity raised by Kymab and maintained the
'190 patent as granted, and issued a written decision documenting these conclusions on February 16, 2024. Further proceedings may follow if appealed by
Kymab before the Technical Board of Appeals. The Company does not expect significant impact on its assets or liabilities as a result of the opposition
proceeding.

11. Stockholders’ Equity
Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are
entitled to dividends when and if declared by the board of directors.
Share Issuances
On January 18, 2021, the Company sold 706,834 common shares, at a price of $28.295 for aggregate proceeds of $16.5 million.
On January 21, 2021, the Company sold 5,575,757 common shares, at a price of $24.75 for aggregate proceeds of $129.4 million.
On November 9, 2021, the Company sold 4,438,597 common shares, at a price of $28.50 for aggregate proceeds of $118.7 million.
In May 2021, the Company entered into an Open Market Sale Agreement (the “Sales Agreement”) with Jefferies LLC (“Jefferies”) to sell from time to time
up to $125.0 million of the Company’s common stock through an “at the market” offering program under which Jefferies acts as the sales agent. Subject to
the terms and conditions of the Sales Agreement, Jefferies could sell the common stock by any method deemed to be an “at-the-market” offering as defined
in Rule 415 promulgated under the Securities Act of 1933, as amended (the “Securities Act”).
Jefferies was entitled to compensation at a commission rate of up to 3.0% of the gross proceeds of shares sold under the Sales Agreement. In connection
with the sale of the common shares on our behalf, Jefferies was deemed to be an “underwriter” within the meaning of the Securities Act and the
compensation of Jefferies was deemed to be underwriting commissions or discounts. The Company agreed to provide indemnification and contribution to
Jefferies with respect to certain liabilities, including liabilities under the Securities Act or the Securities Exchange Act of 1934, as amended, or the
Exchange Act.
As of December 31, 2022, the Company, pursuant to the Sales Agreement, had issued and sold an aggregate of 2,720,846 shares of its common stock
resulting in gross proceeds of $59.5 million, before deducting sales agent fees of $1.7 million.
During the year ended December 31, 2023, the Company sold 3,272,280 shares of its common stock under the Sales Agreement for gross proceeds of
approximately $65.5 million and net proceeds of approximately $63.8 million, after deducting sales agent fees. Having sold approximately $124.9 million
of the $125.0 million available under the Sales Agreement, on May 22, 2023, the Company delivered written notice to Jefferies, effective as of such date, to
terminate the Sales Agreement. The Company was not subject to any termination penalties related to the termination of the Sales Agreement.
On August 9, 2023, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Jefferies LLC, BofA Securities, Inc.,
Guggenheim Securities, LLC and William Blair & Company, L.L.C., as representatives of the several underwriters named therein (collectively, the
“Underwriters”), in connection with the issuance and sale by the Company in a public offering of 6,818,182 common shares of the Company, nominal
value €0.09 per share, at a public offering price of $22.00 per share, less underwriting discounts and commissions, pursuant to an effective shelf registration
statement on Form S-3 and accompanying prospectus (Registration No. 333-255903), which became effective upon filing on May 7, 2021, and a
prospectus supplement thereunder. Under the terms of the Underwriting Agreement, the Company also granted the Underwriters an option exercisable for
30 days to purchase up to an additional 1,022,727 common shares at the public offering price, less underwriting discounts and commissions. On August 10,
2023, the Underwriters exercised this option in full. The offering closed on August 14, 2023, and the Company received net proceeds of $162.2 million,
after deducting underwriting discounts and fees.
12. Collaborations
Lilly
On January 18, 2021, Eli Lilly and Company (“Lilly”) agreed to pay the Company a $40.0 million, non-refundable upfront payment, and purchased
706,834 common shares at a stated price per share of $28.295, for an aggregate purchase price of $20.0 million. The Company and Lilly agreed to
collaborate with respect to the discovery and research of bispecific antibodies utilizing the Company’s proprietary Biclonics® bispecific technology
platform. The collaboration encompasses up to three (3) independent programs directed to the generation of T-cell re-directing bispecific antibodies that
bind CD3 and a tumor associated antigen target selected by Lilly to be the subject of each program.
The objective of each program is to develop a lead compound that Lilly would be able to continue to develop through clinical trials. Lilly agreed to fund the
research activities the Company conducts for each program under an agreed research plan and budget. Lilly receives an exclusive, worldwide, royalty-
bearing, sublicensable license, under certain patent rights and know-how to exploit certain compounds and products directed to designated targets in
combination with targeting CD3, or directed to such designated target(s) alone as a monospecific antibody or monospecific antibody drug conjugate,
subject to rights granted by Merus to third parties under one or more existing third party agreements. Merus retains all rights not granted to Lilly. Lilly has
certain rights to replace selected targets, including the right to substitute a target selection after initial selection for a period of time. The Company may be
entitled to further milestones and royalties in the future dependent on development and commercialization of any resulting product.
F-21
The initial term of the arrangement includes a three-year research term for the Company to perform research and development activities, subject to two
extension terms of six months at Lilly’s discretion. While the arrangement may be terminated in its entirety or on a program-by-program basis at will by
Lilly, there are no direct costs or penalties to Lilly to terminate the arrangement prior to the end of the initial term.
At inception of the arrangement, the Company identified a single performance obligation comprised of a combined delivery of a license and related
activities, including research activities associated with a product candidate against the first target and the activities of the joint steering committee. The
Company also identified two other combined performance obligations relating to options exercisable by Lilly to select a second and third target to advance
a second and third product candidate against the selected targets through discovery and research.
The transaction price at inception was comprised of fixed consideration of $43.5 million that was derived from the $40.0 million upfront payment and
$20.0 million share purchase proceeds, net of the fair value of shares of the shares delivered to Lilly of $16.5 million, and variable consideration associated
with the funding of research services for the product candidate against the first target at inception. All other consideration under the arrangement was
determined to be variable consideration and fully constrained at inception.
The fixed consideration was allocated equally amongst the three performance obligations and the variable consideration associated with each target was
allocated to the performance obligation of each respective target. The equal allocation of the fixed consideration was based on the estimated standalone
selling price of each performance obligation as each was materially the same.
On February 12, 2021, the Company and Lilly completed the initial exchange of fixed consideration and transfer of common shares. The Company initially
deferred $43.5 million allocated to the performance obligations to be recognized as revenue over time using a cost-to-cost measure of progress toward the
development of a lead compound for each respective target, anticipated to be recognized as revenue within the initial research term, along with research
funding. Development milestones, commercialization milestones and royalties are variable consideration, fully constrained, to be included in the
transaction price for each performance obligation and recognized in future periods in accordance with the Company’s revenue recognition policy. The
revenue recognized relating to each combined performance obligation is presented in the notes according to the source of consideration received (upfront,
reimbursement revenue, milestone), reflective of their differing timing of receipt.
During the year ended December 31, 2022, Lilly substituted one of the target programs. The program timeline is expected to extend beyond the original
research term. Under the current research plan, for the program to be completed in collaboration with Merus, Lilly would be required to extend the research
term to 2025, subject to its discretion. Lilly exercised the first six month extension in October 2023 for which there was no associated fee. The program
timeline is expected to extend beyond this first extension, and such an extension into 2025 would result in a fee of $0.5 million. The $0.5 million extension
is included in the Lilly cost-to-cost model as of December 31, 2023 and December 31, 2022.
As of December 31, 2023, research activities were on-going and no milestones have been achieved to date.
Incyte
In December 2016, pending regulatory clearance, Incyte Corporation (“Incyte”) agreed to pay the Company a $120.0 million, non-refundable upfront
payment, and purchased 3.2 million common shares at a stated price per share of $25.00, for an aggregate purchase price of $80.0 million. In exchange, the
Company granted Incyte with a license to certain of its intellectual property and committed to collaborate with Incyte to research, discover and develop
monospecific or bispecific antibodies utilizing the Company’s proprietary bispecific technology platform. The collaboration is managed by a joint steering
committee in which both parties are represented and is tasked with overseeing the activities which significantly contributes to the collaboration. The
collaboration may encompass up to 10 product candidates that result from the Company’s application of its proprietary Biclonics® technology platform.
During the course of the initial research term, Merus proposes product candidates to Incyte, which evaluates whether to designate proposed product
candidates from the Company to make a selection for further research. Proposed product candidates begin at a pre-clinical stage of development. Incyte has
certain rights to replace product candidates, including the right to substitute a product candidate after initial selection. The Company would be entitled to
future consideration in the form of cost reimbursements for research services, development milestones, commercialization milestones and royalties related
to the programs under the arrangement.
At inception of the collaboration, two potential bispecific product candidates were under preliminary evaluation. After further research, a lead candidate
was ultimately selected for the first product candidate, designated MCLA-145, and the other potential product candidate was not pursued. For the
designated product candidate (MCLA-145), the Company retained the exclusive right to develop and commercialize products and product candidates in the
United States, while Incyte obtained the exclusive right to develop and commercialize products and product candidates arising from such program outside
the United States. For MCLA-145, the parties will conduct and share equally the costs of mutually agreed global development activities and will be solely
responsible for independent development activities in each party’s respective territories. For all other programs under the arrangement to be selected by
Incyte, Incyte will be responsible for all research, development and commercialization costs. The Company may elect to co-fund the development of
certain of the other programs in the future, in which case costs and benefits would be shared. The Company has not elected to co-fund any programs to
date.
F-22
At inception of the arrangement, the Company identified a performance obligation comprised of a combined delivery of a license and related activities,
including the activities of the joint steering committee, to which to allocate consideration. The arrangement also allowed for optional future research
services to advance selected product candidates through discovery and research. The transaction price was comprised of fixed consideration of an upfront
payment of $120.0 million and proceeds from the sale of shares of $80.0 million. All other consideration under the arrangement was determined to be
variable consideration and fully constrained at inception. $152.6 million of the transaction price was allocated to the license and related activities
performance obligation after accounting for the purchase of common shares by Incyte.
On January 23, 2017, the Company completed the sale of shares and exchange of the license. The Company initially deferred $152.6 million of the
transaction price allocated to the license and related performance obligation as deferred revenue, to be recognized as revenue over time as the primary
benefit of the license to Incyte is access to the Company’s intellectual property covering its Biclonics® technology platform for the generation of potential
product candidates. Development milestones, commercialization milestones and royalties are variable consideration, fully constrained, to be recognized in
future periods in accordance with the Company’s revenue recognition policy. Cost reimbursements for research services are recognized as they are
performed over time as these are considered a separate performance obligation.
In January 2022, the Company announced that Incyte elected to opt-out of its ex-U.S. development of MCLA-145, from the parties joint collaboration
agreement executed in 2017. At inception of the collaboration, for the designated product candidate (MCLA-145), the Company retained the exclusive
right to develop and commercialize products and product candidates in the United States, while Incyte obtained the exclusive right to develop and
commercialize products and product candidates arising from such program outside the United States. For MCLA-145, the parties conducted and shared
equally the costs of mutually agreed global development activities. Incyte’s opt-out of ex-U.S. rights to MCLA-145 provides the Company the exclusive
right to develop and commercialize potential MCLA-145 products globally. Under the collaboration, Incyte will continue to support the program for a
limited time while ex-U.S. activities are transitioned to the Company, and Incyte will retain a right to a residual royalty of up to 4% on sales of future
commercialization of MCLA-145, if approved.
During the year ended December 31, 2023, the Company recognized a $2.5 million milestone from Incyte related to the initiation of a Phase 1 study with
respect to a novel target pair program, a second $2.5 million milestone from Incyte related to the initiation of a Phase 1 study with respect to a novel target
pair program, and a $1.0 million milestone from Incyte related to candidate nomination. There were no additional development or commercialization
milestones recognized during the year ended December 31, 2023. During the year ended December 31, 2022, the Company recognized a total of $1.0
million in development milestones. During the year ended December 31, 2021, the Company recognized a total of $2.0 million in development milestones.
Ono
In April 2014, the Company granted Ono Pharmaceutical Co., Ltd. (“Ono”) an exclusive, worldwide, royalty-bearing license, with the right to sublicense,
research, test, make, use and market a limited number of bispecific antibody candidates based on the Company’s Biclonics® technology platform against
two undisclosed targets directed to a particular undisclosed target combination.
On March 14, 2018, the Company granted Ono an exclusive, worldwide, royalty-bearing license, with the right to sublicense, research, test, make, use and
market a limited number of bispecific antibody candidates based on the Company’s Biclonics® technology platform against two undisclosed targets
directed to a particular undisclosed target combination. Ono is responsible for identifying lead candidates and conducting further non-clinical and clinical
development activities for such licensed bispecific antibodies and pharmaceutical products containing such antibodies, including manufacture and process
development. Additionally, Ono controls and has exclusive rights over the worldwide commercialization of any approved products, including worldwide
supply, and is solely responsible for all costs and expenses related to commercialization. Ono has also agreed to fund the Company’s research and
development activities and be responsible for the payment of all costs and expenses for its own research and development activities, which are set out in a
mutually agreed upon research plan. The Company retains all rights to use and commercialize any antibodies that are generated under the collaborative
research program, excluding the up to five lead and/or selected antibodies against the targets Ono is pursuing, provided that the use and commercialization
is not with respect to the particular target combination. Ono agreed to pay the Company an upfront, non-refundable payment of €0.7 million. In addition,
the Company was entitled to €0.3 million intended to compensate the Company for research services already completed upon entering into the agreement,
and €0.2 million to be paid to the Company over time for full time equivalent funding. The Company is entitled to research and development milestones in
addition to royalties on future sales. The Company identified performance obligations for: (1) provision of a license for the target combination, and (2)
research and development services. The Company concluded that Ono would be able to develop and benefit from the license, independent of the research
and development services. The research and development services are capable of being performed by third parties with an appropriate sub-license, and are
recognized over time as these services are delivered. Milestone payments are fully constrained as variable consideration to be recognized in future periods
in accordance with the Company’s revenue recognition policy.
F-23
There were no development milestones achieved in the year ended December 31, 2023. The Company achieved a €1.0 million (approximately $1.0 million)
development milestone in the year ended December 31, 2022. There were no development milestones achieved in the year ended December 31, 2020.
Simcere
In January 2018, the Company granted Simcere Pharmaceuticals Group (“Simcere”) an exclusive license to develop and commercialize up to three
bispecific antibodies to be produced by Merus utilizing the Company’s Biclonics® technology platform in China (the “Simcere Agreement”). The Company
will retain all rights outside of China. The Company has agreed to lead research and discovery activities, while Simcere has agreed to be responsible for the
Investigational New Drug (“IND”) enabling studies, clinical development, regulatory filings and commercialization of these potential product candidates in
China. The Company received an upfront, non-refundable payment of $2.75 million, relating to three separate research programs.
At inception of the arrangement, the Company identified three performance obligations comprised of the combined delivery of a license and performance
of research and development activities with respect to each program. The Company performs research and development activities to achieve candidate
nomination. The Company concluded that these activities were not distinct from the underlying license for each program as Simcere would not be able to
benefit from the license apart from research and development activities at this phase of development.
The transaction price under the arrangement comprised fixed consideration of $2.75 million. The transaction price was allocated to each separate
performance obligation on a relative standalone fair value basis. The Company deferred the portion of the upfront payment allocated to the three
performance obligations as deferred revenue, to be recognized over time. Compensation for research and development services prior to candidate
nomination are allocated to each program performance obligation and also recognized over time. Development milestone payments allocated to each of the
program performance obligations are constrained as variable consideration to be recognized in future periods in accordance with the Company’s revenue
recognition policy.
The Company has achieved three milestones under this agreement and has received an aggregate of $1.8 million in milestone payments. During the years
ended December 31, 2021 and 2020, the Company recognized $0.5 million for milestones achieved under the Simcere Agreement, respectively. In January
2022, the Company and Simcere terminated the Simcere Agreement, effective March 30, 2022. There were no milestones achieved during the year ended
December 31, 2023.
Betta
On December 10, 2018, the Company granted Betta an exclusive license to develop and commercialize in China MCLA-129, proprietary Biclonics®
produced by its Biclonics® technology platform. The Company retains all rights outside of China. Betta has agreed to retain a contract manufacturing
organization with experience in filing IND applications with U.S. regulatory authorities and CTAs with European regulatory authorities in order to produce
clinical trial materials for the Chinese market and rest of the world. As a key strategic component of the collaboration, Betta will be responsible for IND
enabling studies and manufacturing of clinical trial materials in China, which the Company intends to use to assist regulatory filing and early stage clinical
development in the rest of the world.
In addition to a non-refundable upfront payment of $1.0 million, Betta and the Company will share equally the cost of the transfer of the manufacturing
technology to a contract manufacturing organization. The Company is also eligible to receive an aggregate of $12.0 million in milestone payments
contingent upon Betta achieving certain specified development and commercial goals as well as tiered royalty payments of net sales of any products
resulting from the collaboration in China. In turn, Betta is also entitled to milestone payments based on the Company’s progress.
The Company identified a single combined performance obligation, being the delivery of the MCLA-129 license including activities necessary to complete
the technology transfer. The Company had no other commitments. The transaction price is comprised of fixed consideration of $1.0 million and fully
allocated to the single performance obligation which would be fulfilled at a point in time. The technology transfer to deliver the license was completed in
2018 and Company recognized the revenue related to this performance obligation of $1.0 million as revenue for the year ended December 31, 2018.
Development milestone payments allocated to the performance obligation are constrained as variable consideration to be recognized in future periods in
accordance with the Company’s revenue recognition policy.
To date, both the Company and Betta have achieved a development milestone both valued at $2.0 million. The amounts were recognized as milestone
revenue of $2.0 million and research and development cost of $2.0 million in the Company’s statement of operations for the year ended December 31,
2020. No milestones were achieved during the years ended December 31, 2023, 2022, and 2021, respectively.

13. Employee Benefit Plans
Share-Based Compensation
2010 Plan
In 2010, the Company established the Merus B.V. 2010 Employee Option Plan (the “2010 Plan”) that entitled key management personnel, staff and
consultants providing similar services to purchase shares in the Company. Under the 2010 Plan, holders of vested options were entitled to purchase
depositary receipts for common shares at the exercise price determined at the date of grant. Upon exercise of the option, common shares were issued to a
foundation established to facilitate administration of share-based compensation awards and pool the voting interests of the underlying shares, and
depositary receipts were issued by the foundation to the individual holders. In connection with the IPO, the 2010 Plan was amended to cancel the
depositary receipts and allow individual holders to directly hold the common shares obtained upon exercise of their options.
Options granted under the 2010 Plan generally vest in installments over a four-year period from the grant date: 25% on the first anniversary of the vesting
commencement date, and the remaining 75% of the options vest in 36 monthly installments for each full month of continuous service provided thereafter.
Options expire after 8 years from the date of grant. The last grant of options pursuant to the 2010 Plan occurred in 2016, with no further grants awarded.
All grants from the 2010 Plan were either exercised or terminated as of December 31, 2023.
2016 Plan
In 2016, the Company established the 2016 Incentive Award Plan (the “2016 Plan”). All incentive award grants since 2016 are being made under the 2016
Plan.
Options granted to employees under the 2016 Plan generally vest in installments over a four-year period from the grant date: 25% vest on the first
anniversary of the vesting commencement date, and the remaining 75% of the options vest in 36 monthly installments for each full month of continuous
service provided thereafter. Certain options may vest dependent on the attainment of performance criteria. Options expire after 10 years from the date of
grant.
Options granted to non-executive directors consist of initial option grants as well as subsequent annual awards. The initial award of options granted vest in
installments over a three-year period: 33% of the options vest on the first anniversary of the vesting commencement date, and 67% of the options vest in 24
monthly installments thereafter. Each subsequent award vests over a one-year period in 12 monthly installments. The Company measures the fair value of
an option through the application of an option pricing model, as more fully described below.
The RSUs granted to employees under the 2016 Plan vest in installments over a four-year period from the grant date. Certain RSUs may vest dependent on
the attainment of performance criteria. Each RSU represents the right to receive one common share. The fair value of an RSU is determined by reference to
the price of the underlying common share.
The number of common shares authorized for issuance for future grants under the 2016 Plan as of January 1, 2024 totaled 2,005,113.
Share-Based Compensation Expense
Share-based compensation expense is classified in the consolidated statements of operations and comprehensive loss as follows:

As of December 31, 2023, share-based compensation expense related to unvested shares was $19.1 million. These shares are expected to vest and related
costs are expected to be recognized over a weighted average remaining vesting period of 1.3 years.
F-27
Stock Option Valuation
The Company uses the Black-Scholes option-pricing model to measure the fair value of stock option awards. Key weighted average assumptions used in
this pricing model on the date of grant for options granted to employees are as follows:
Risk-free interest rate
Contractual life of options (years)
Expected term of options (years)
Expected volatility of underlying stock
Expected dividend yield
2023
Year Ended December 31,

6.3
75.5 %
0.0 %
0.6 %

6.1
85.7 %
0.0 %
The risk-free interest rate is based upon the U.S. Treasury yield curve in effect at the time of grant, with a term that approximates the expected life of the
option. Prior to April 1, 2022, the Company determined the expected volatility using a blended approach encompassing its historical experience and the
historical volatility of a peer group of comparable publicly traded companies with product candidates in similar stages of development to the Company’s
product candidates. From April 1, 2022 onward, the expected volatility is based on the annualized daily historical volatility of the Company's stock price
for a time period consistent with the expected term of each grant. A simplified method using a weighted-average mid-point between an award’s vesting date
and expiry is used to estimate the expected life of options in all periods presented as a sufficient history of participant exercise behavior is not readily
observable. The Company has applied an expected dividend yield of 0.0% as the Company has not historically declared a dividend and does not anticipate
declaring a dividend during the expected life of the options.

The Company has established a post-employment benefit plan for employees of the Netherlands that entitles executive officers and other staff members to
retire at the age of 67 and receive annual payments based upon the average salary earned during the service period. The Company has insured the benefit
liabilities through purchased non-participating annuities from an insurance company and has no other obligation other than to pay the annual insurance
premiums to the insurance company. After purchasing the insurance, the Company has no further obligation (legal or constructive) to pay further amounts
if the insurance fund has insufficient assets to pay all employee benefits relating to current and prior service. Contributions to purchase non-participating
annuities are expensed as incurred as service costs. Company contributions to the post-employment benefit plan totaled $1.6 million, $2.8 million, and $2.9
million in the years ended December 31, 2023, 2022 and 2021, respectively.
401(k) Savings Plan
The Company has a defined contribution 401(k) savings plan (the “401(k) Plan”). The 401(k) Plan covers substantially all U.S. employees, and allows
participants to defer a portion of their annual compensation on a pretax basis. The Company matches contributions to the 401(k) Plan, matching 50% of an
employee’s contribution up to a maximum of 3% of the participant’s compensation. Company contributions to the 401(k) Plan totaled $0.3 million, $0.2
million, and $0.1 million for the years ended December 31, 2023, 2022, and 2021, respectively.
Executive Settlement
In December 2019, in connection with the departure of the Chief Executive Officer of the Company, the Company awarded benefits, including the
following: cash compensation of $0.9 million, a grant of 30,000 RSUs, extended vesting of his equity incentive awards through June 30, 2021 and extended
exercisability of his equity incentive awards through December 31, 2021. The cash compensation was paid by the Company in January 2020. There were
no substantive service conditions associated with the benefits awarded other than the passage of time. The Company incrementally recognized $1.8 million
in general and administrative expense associated with these benefits in the consolidated statement of operations for the year ended December 31, 2019.
In April 2020, Mark Throsby, Ph.D. resigned as the Executive Vice President and Chief Scientific Officer of the Company effective July 31, 2020. In
connection with his departure, Mr. Throsby entered into a Settlement Agreement with the Company, pursuant to which Mr. Throsby received a severance
payment equal to 8 months of his annual salary and amortized bonus aggregating approximately $0.3 million. Further, subject to Mr. Throsby’s continued
compliance with the terms and conditions of the Settlement Agreement, Mr. Throsby’s unvested equity awards continued to vest until October 31, 2020 as
if Mr. Throsby had continued in full time service with the Company through such date. The post-termination exercise period of Mr. Throsby's options was
extended to March 31, 2021. The Company incrementally recognized $0.1 million in respect of the severance payment and a net reversal of $0.4 million of
share-based compensation expense in respect of share-based compensation in research and development expense in the consolidated statement of
operations in the prior year ended December 31, 2019.
In March 2021, the Company and Mr. Throsby amended the Settlement Agreement, extending the post-termination expiration period of his outstanding
options to extend to October 31, 2021, three months following his performance of certain consulting services through July 31, 2021. As a result, additional
compensation cost of $0.2 million was recognized for the quarter ended March 31, 2021. During the three months ended September 30, 2021, the Company
and Mr. Throsby entered into the 2nd Amendment to the Settlement Agreement, extending Mr. Throsby’s consulting services period to November 30, 2021.
The 2nd Amendment extends the post-termination expiration period of his outstanding options to February 28, 2022. As the modification occurred in Mr.
Throsby’s post-employment period, the options cease to be within the scope of ASC 718 and are recharacterized as an issuance of a standalone derivative
instrument. The Company recognized a $1.0 million net loss associated with the derivative instrument included as other losses, net in the statement of
operations for the year ended December 31, 2021. The Company recognized a $0.4 million net gain associated with the derivative instrument included as
other income in the statement of operations during the year ended December 31, 2022. The Company did not recognize any further gains or expenses
during the year ended December 31, 2023 and the Company does not expect to incur any further expenses as Mr. Throsby's option to exercise expired in
May 2022.

The Company has entered into the Incyte collaboration and license agreement and the Incyte share subscription agreement in which the terms and
transactional amounts incurred between Incyte and the Company are more fully described in Note 12. Incyte is a shareholder with holdings representing
approximately 6.9%, 7.7% and 8.2% of the outstanding shares of the Company as of December 31, 2023, 2022 and 2021, respectively. During the year
ended December 31, 2021, Incyte’s holdings of the Company’s outstanding shares fell below 10.0% of the Company’s total outstanding shares due to the
Company issuing additional shares of common stocks through various financing events of 2021. These consolidated financial statements present Incyte as a
related party for the year ended December 31, 2021 in order to simplify the presentation and clearly display transactional amounts incurred between Incyte
and the Company, given the related party relationship in effect for a portion of the year. The consolidated financial statements for the years ended
December 31, 2023 and 2022 do not reflect Incyte as a related party.

MERUS N.V. POLICY FOR RECOVERY OF ERRONEOUSLY AWARDED COMPENSATION
Merus N.V. (the “Company”) has adopted this Policy for Recovery of Erroneously Awarded Compensation (the
“Policy”), effective as of September 27, 2023 (the “Effective Date”). Capitalized terms used in this Policy but not otherwise
defined herein are defined in Section 11.
Exhibit 97.1
1.
Persons Subject to Policy
This Policy shall apply to current and former Officers of the Company.
2. Compensation Subject to Policy
This Policy shall apply to Incentive-Based Compensation received on or after the Effective Date. For purposes of this
Policy, the date on which Incentive-Based Compensation is “received” shall be determined under the Applicable Rules, which
generally provide that Incentive-Based Compensation is “received” in the fiscal period during which the relevant Financial
Reporting Measure is attained or satisfied, without regard to whether the grant, vesting or payment of the Incentive-Based
Compensation occurs thereafter.
3. Recovery of Compensation
In the event that the Company is required to prepare a Restatement, the Company shall recover, reasonably promptly, the
portion of any Incentive-Based Compensation that is Erroneously Awarded Compensation, unless the Committee has determined
that recovery would be Impracticable. Recovery shall be required in accordance with the preceding sentence regardless of
whether the applicable Officer engaged in misconduct or otherwise caused or contributed to the requirement for the Restatement
and regardless of whether or when restated financial statements are filed by the Company. For clarity, the recovery of
Erroneously Awarded Compensation under this Policy will not give rise to any person’s right to voluntarily terminate
employment for “good reason,” or due to a “constructive termination” (or any similar term of like effect) under any plan,
program or policy of or agreement with the Company or any of its affiliates.
4. Manner of Recovery; Limitation on Duplicative Recovery
The Committee shall, in its sole discretion, determine the manner of recovery of any Erroneously Awarded
Compensation, which may include, without limitation, reduction or cancellation by the Company or an affiliate of the Company
of Incentive-Based Compensation or Erroneously Awarded Compensation, reimbursement or repayment by any person subject to
this Policy of the Erroneously Awarded Compensation, and, to the extent permitted by law, an offset of the Erroneously Awarded
Compensation against other compensation payable by the Company or an affiliate of the Company to such person.
Notwithstanding the foregoing, unless otherwise
|US-DOCS\142290969.1||
1
prohibited by the Applicable Rules, to the extent this Policy provides for recovery of Erroneously Awarded Compensation
already recovered by the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 or Other Recovery Arrangements,
the amount of Erroneously Awarded Compensation already recovered by the Company from the recipient of such Erroneously
Awarded Compensation may be credited to the amount of Erroneously Awarded Compensation required to be recovered pursuant
to this Policy from such person.
5. Administration
This Policy shall be administered, interpreted and construed by the Committee, which is authorized to make all
determinations necessary, appropriate or advisable for such purpose. The Board of Directors of the Company (the “Board”) may
re-vest in itself the authority to administer, interpret and construe this Policy in accordance with applicable law, and in such event
references herein to the “Committee” shall be deemed to be references to the Board. Subject to any permitted review by the
applicable national securities exchange or association pursuant to the Applicable Rules, all determinations and decisions made by
the Committee pursuant to the provisions of this Policy shall be final, conclusive and binding on all persons, including the
Company and its affiliates, equityholders and employees. The Committee may delegate administrative duties with respect to this
Policy to one or more directors or employees of the Company, as permitted under applicable law, including any Applicable Rules.
6.
Interpretation
This Policy will be interpreted and applied in a manner that is consistent with the requirements of the Applicable Rules,
and to the extent this Policy is inconsistent with such Applicable Rules, it shall be deemed amended to the minimum extent
necessary to ensure compliance therewith.
7. No Indemnification; No Liability
The Company shall not indemnify or insure any person against the loss of any Erroneously Awarded Compensation
pursuant to this Policy, nor shall the Company directly or indirectly pay or reimburse any person for any premiums for third-party
insurance policies that such person may elect to purchase to fund such person’s potential obligations under this Policy. None of
the Company, an affiliate of the Company or any member of the Committee or the Board shall have any liability to any person as
a result of actions taken under this Policy.
8. Application; Enforceability
Except as otherwise determined by the Committee or the Board, the adoption of this Policy does not limit, and is
intended to apply in addition to, any other clawback, recoupment, forfeiture or similar policies or provisions of the Company or
its affiliates, including any such policies or provisions of such effect contained in any employment agreement, bonus plan,
incentive plan, equity-based plan or award agreement thereunder or similar plan, program or agreement of the
2
Company or an affiliate or required under applicable law (the “Other Recovery Arrangements”). The remedy specified in this
Policy shall not be exclusive and shall be in addition to every other right or remedy at law or in equity that may be available to
the Company or an affiliate of the Company.
9. Severability
The provisions in this Policy are intended to be applied to the fullest extent of the law; provided, however, to the extent
that any provision of this Policy is found to be unenforceable or invalid under any applicable law, such provision will be applied
to the maximum extent permitted, and shall automatically be deemed amended in a manner consistent with its objectives to the
extent necessary to conform to any limitations required under applicable law.
10. Amendment and Termination
The Board or the Committee may amend, modify or terminate this Policy in whole or in part at any time and from time
to time in its sole discretion. This Policy will terminate automatically when the Company does not have a class of securities listed
on a national securities exchange or association.
11. Definitions
“Applicable Rules” means Section 10D of the Exchange Act, Rule 10D-1 promulgated thereunder, the listing rules of the
national securities exchange or association on which the Company’s securities are listed, and any applicable rules, standards or
other guidance adopted by the Securities and Exchange Commission or any national securities exchange or association on which
the Company’s securities are listed.
“Committee” means the committee of the Board responsible for executive compensation decisions comprised solely of
independent directors (as determined under the Applicable Rules), or in the absence of such a committee, a majority of the
independent directors serving on the Board.
“Erroneously Awarded Compensation” means the amount of Incentive-Based Compensation received by a current or
former Officer that exceeds the amount of Incentive-Based Compensation that would have been received by such current or
former Officer based on a restated Financial Reporting Measure, as determined on a pre-tax basis in accordance with the
Applicable Rules.
“Exchange Act” means the Securities Exchange Act of 1934, as amended.
“Financial Reporting Measure” means any measure determined and presented in accordance with the accounting
principles used in preparing the Company’s financial statements, and any measures derived wholly or in part from such measures,

3
“GAAP” means United States generally accepted accounting principles.
“IFRS” means international financial reporting standards as adopted by the International Accounting Standards Board.
“Impracticable” means (a) the direct costs paid to third parties to assist in enforcing recovery would exceed the
Erroneously Awarded Compensation; provided that the Company (i) has made reasonable attempts to recover the Erroneously
Awarded Compensation, (ii) documented such attempt(s), and (iii) provided such documentation to the relevant listing exchange
or association, (b) to the extent permitted by the Applicable Rules, the recovery would violate the Company’s home country laws
pursuant to an opinion of home country counsel; provided that the Company has (i) obtained an opinion of home country counsel,
acceptable to the relevant listing exchange or association, that recovery would result in such violation, and (ii) provided such
opinion to the relevant listing exchange or association, or (c) recovery would likely cause an otherwise tax-qualified retirement
plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C.
401(a)(13) or 26 U.S.C. 411(a) and the regulations thereunder.
“Incentive-Based Compensation” means, with respect to a Restatement, any compensation that is granted, earned, or
vested based wholly or in part upon the attainment of one or more Financial Reporting Measures and received by a person: (a)
after beginning service as an Officer; (b) who served as an Officer at any time during the performance period for that
compensation; (c) while the issuer has a class of its securities listed on a national securities exchange or association; and (d)
during the applicable Three-Year Period.
“Officer” means each person who serves as an executive officer of the Company, as defined in Rule 10D‑1(d) under the
Exchange Act.
“Restatement” means an accounting restatement to correct the Company’s material noncompliance with any financial
reporting requirement under securities laws, including restatements that correct an error in previously issued financial statements
(a) that is material to the previously issued financial statements or (b) that would result in a material misstatement if the error
were corrected in the current period or left uncorrected in the current period.
“Three-Year Period” means, with respect to a Restatement, the three completed fiscal years immediately preceding the
date that the Board, a committee of the Board, or the officer or officers of the Company authorized to take such action if Board
action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare such
Restatement, or, if earlier, the date on which a court, regulator or other legally authorized body directs the Company to prepare
such Restatement. The “Three-Year Period” also includes any transition period (that results from a change in the Company’s
fiscal year) within or immediately following the three completed fiscal years identified in the preceding sentence. However, a
transition period between the last day of the Company’s previous fiscal year end and the first day of its new fiscal year that
comprises a period of nine to 12 months shall be deemed a completed fiscal year.
