Item 1. Business



Overview



We are an innovative biopharmaceutical company developing a
novel and proprietary class of biologic drugs for the selective modulation of the human immune system to treat a broad range of
cancers and autoimmune disorders. We believe our innovative CUE BiologicsTM platform approach to selectively modulate disease
relevant T cells, provides a transformative solution to the challenges facing prevailing immunotherapeutics. By directly engaging
and modulating disease relevant T cells in the patient’s body via an injectable drug, we believe our biologic drug candidates
will be able to realize the true potential of immune modulation. Through our proprietary CUE BiologicsTM platform, we believe
we are uniquely positioned to become a prominent and leading player in immunotherapy, immuno-oncology, and autoimmune disease.
While currently in preclinical development, our proprietary platform is intended to allow us to efficiently design and develop
drug candidates that specifically and selectively engage disease relevant T cells for therapeutic affect, while minimizing or
eliminating unwanted side effects. We have been aggressively seeking patent protection for our pioneering innovations and, combined
with a license agreement with the Albert Einstein College of Medicine (“Einstein”), continue to build a robust intellectual
property portfolio. This portfolio includes our core technology platform for the engineering of biologics to selectively control
T cell activity, which we call CUE BiologicsTM, a growing portfolio of precision immuno-modulatory drug candidates, and two
supporting technologies we call MODTM and viraTopeTM that enable the discovery of costimulatory signaling molecules
(ligands) and T cell targeting peptides, respectively.



Background



The human immune system comprises a number of specialized cell
types which collectively function to identify and defend the body against foreign threats. Central to the proper functioning of
the immune system are the coordinated activities and communications between two specialized cell types, antigen-presenting cells
(“APCs”) and T cells. APCs serve to capture and break the proteins from foreign organisms, (e.g., bacteria and viruses),
or abnormal proteins (e.g., from genetic mutation in cancer cells) into smaller fragments suitable as signals for scrutiny by the
larger immune system, including T cells. In particular, APCs break down proteins into small peptide fragments, which are then paired
with a class of host molecules called the major histocompatibility complex (“MHC”) and displayed on the cell surface.
Cell surface display of an MHC together with a peptide fragment, also known as a T cell epitope, provides the underlying scaffold
surveilled by T cells, allowing for specific recognition. The peptide fragments can be pathogen-derived, tumor-derived, or derived
from natural host proteins (self-proteins). Moreover, APCs can recognize certain pathogen associated molecules, such as bacterial
toxins, viral proteins, viral nucleic acids, that communicate the pathogenic threat to the APC. The APCs relay this information
to T cells through additional costimulatory signals in order to generate a more effective response.



T cells recognize peptide-MHC (“pMHC”) complexes
through a specialized cell surface receptor, the T cell receptor (“TCR”). The TCR is unique to each T cell and, as
a consequence, each T cell is highly specific for a particular pMHC target. In order to adequately address the universe of potential
threats, a very large number (~10,000,000) of distinct T cells with distinct TCRs exist in the human body. Further, any given T
cell, specific for a particular T cell peptide, is initially a very small fraction of the total T cell population. Although normally
dormant and in limited numbers, T cells bearing specific TCRs can be readily activated and amplified by APCs to generate highly
potent T cell responses that involve many millions of T cells. Such activated T cell responses are capable of attacking and clearing
viral infections, bacterial infections, and other cellular threats including tumors, as illustrated below. Conversely, the broad,
non-specific activation of overly active T cell responses against self or shared antigens can give rise to T cells inappropriately
attacking and destroying healthy tissues or cells.



2











Activated T cells target tumor cells
for killing through engagement of the TCR with its cognate pMHC.



TCR engagement by its specific or cognate pMHC delivers an activation
signal to the T cell and defines the specificity of the response. However, robust and effective T cell activation requires that
the TCR signal be accompanied by additional signals from the APC, collectively referred to as “costimulation.” The
sum of these interactions directs the quality and magnitude of the T cell response. Specific costimulatory, as well as coinhibitory
signals, may be delivered by the APC to the T cell through specific signaling molecules (ligands) interacting with their cognate
receptors at the interface of these two cells, shown below. Based upon the particular nature of the pMHC and costimulatory signal(s),
the T cell may differentiate into a variety of cell types, each with a specialized function (e.g., Tc1, Tc2, Th1, Th2, Th17, Treg,
Tr1, etc.). Hence communication between APCs and T cells must be capable of precisely identifying threats and generating a response
of appropriate quality and magnitude. An insufficient T cell response may result in a persistent pathogenic infection, or in the
case of cancer, tumor persistence. Conversely, an excessive or inappropriate T cell response may damage the host acutely (e.g.,
acute viral hepatitis) or chronically through autoimmune disease (e.g., Type 1 diabetes, celiac disease, rheumatoid arthritis,
Graves’ disease, etc.).

Cancer is characterized by the uncontrolled proliferation of
abnormal cells and is a leading cause of death in developed countries. Cancer cells arise when proteins responsible for regulating
cell division, proliferation or death are altered and these changes can occur through several different mechanisms. Cancer cells
may express particular proteins (antigens) at much higher levels than normal (collectively referred to as tumor associated antigens,
e.g., PSA-1 and Wilms Tumor 1) or express oncogenic (tumor-causing) viral proteins that are responsible for transformation, producing
so-called cancer “drivers”, such as HPV E7. Cells can also be rendered oncogenic by the damage of host proteins through
mutation (e.g., p53 and KRAS), which result in the expression of cancer neoantigens. Regardless of the nature of oncogenesis, cancer
cells can display on their cell surface antigenic peptides, which are often recognized by the immune system.



In addition to being transformed, cancer cells have the ability
to evade or modulate immune surveillance. This “immune escape” can be a key factor in their growth, spread, and persistence.
Cancer cells employ a variety of approaches to escape immune surveillance or to suppress the effects of an immune response. One
example of this is observed when cancer cells evade a normal immune response by expressing cell surface molecules that interact
with and inhibit the attacking immune cells. These inhibitory interactions, called “immune checkpoints,” provide the
tumor with a shield or buffer from activated and tumor-specific T cells. Checkpoint pathway inhibitors are therapeutic antibodies
in immuno-oncology that are designed to block the tumor’s inhibitory shield; they have demonstrated promising clinical results.
Another mechanism by which tumors can turn down the immune response is by stimulating the production of CD4+ regulatory T cells
(“Tregs”), which in turn inhibit the killer CD8+ T cells that would normally attack the cancer. Thus, through one or
more of these different pathways, the cancer cells manipulate and bias the local tumor microenvironment in favor of immune cell
suppression. To extend and enhance the observed clinical benefits of therapeutic checkpoint blockade, a concurrent means of specifically
activating and expanding a tumor-specific CD8+ T cell population is desired. Of interest, recent results from cancer trials that
focus on activating a general (non-specific) immune response have shown that globally stimulated immune cells can attack “self”
tissue, thereby triggering a therapeutically-induced autoimmune disease, frequently observed in patients as a consequence of their
treatment and can limit further therapy.



In autoimmune and inflammatory diseases, components of the immune
system are unable to effectively distinguish between foreign and “self” tissues and so the immune system mounts a response
that can result in extensive destruction of normal tissue. Autoimmune and inflammatory diseases often occur in genetically predisposed
individuals and can be triggered by select conditions, such as infection or tissue damage. The result is an immune response against
healthy tissue, amounting to the second highest cause of chronic illness in the United States and a leading cause of death for
women under 65.



In order to eliminate tumor cells and infectious agents, the
immune system needs to be amplified, whereas for the effective treatment of autoimmune and inflammatory diseases, the immune response
needs to be specifically suppressed. Certain T cell populations are known to be critical to the development and persistence of
T cell-mediated autoimmune diseases. In the case of autoimmune diabetes, for example, effector T cells can kill insulin-producing
cells of the pancreas through direct and indirect mechanisms. Once most insulin-producing cells have been destroyed by the aberrant
T cell response, the patient is no longer able to regulate blood glucose levels and develops diabetes. In addition to disease-causing
effector T cells (Teff), there exist populations of regulatory T cells (Tregs), which act to inhibit such dangerous responses in
normal individuals. Tregs are able to inhibit the destructive activity of Teff and are part of the immune system’s control
apparatus.



We believe that our technology can be used to specifically treat
autoimmune disease. We are working on two different approaches: (1) the direct inhibition and/or deletion of the pathogenic autoimmune
effector T cells and (2) the control of the effector T cells’ function through the expansion and activation of Tregs.



Immunotherapy



During the last five years, there has been substantial scientific
progress in therapeutically modifying the function of immune cells (“immunotherapies”), such as T cells, to either
enhance tumor killing in the context of oncology, or protect tissue in the context of autoimmune disease. Immunotherapies are therefore
increasingly recognized as an essential aspect of the emerging opportunities in the treatment of cancer and autoimmune disease.
Despite the tremendous promise of these therapies, there are a number of continuing challenges. For example, most of the currently
used cancer immunotherapies rely on non-specific and general activation of T cells or the inhibition of costimulatory pathways
(e.g., checkpoint pathway inhibitors), both of which result in the global, non-specific stimulation of T cells. The global and
nonspecific engagement by many current immunotherapeutics results in the activation of a large fraction of disease-irrelevant T
cells, rather than selective activation of those T cells which can therapeutically affect the disease by virtue of their antigen-specific
TCRs. The net effect of this approach is typically an extremely narrow therapeutic window in which many of the stimulated T cells
are not selective towards the tumor, and often recognize “self antigens”. This results in significant toxicity and
serious side effects and, in severe cases (e.g., ProleukinTM and YervoyTM), fatalities. Similarly, for the treatment
of autoimmune indications, previous immunotherapies have been non-specific and broadly suppress immune function (e.g., HumiraTM,
cyclosporine and methotrexate) and thus potentially predispose patients to deadly infections, and cancer.



4







Checkpoint pathway inhibitors modulate the costimulatory pathways
described and illustrated above by blocking the function of inhibitory receptors which would normally suppress the activation of
T cells, so-called “immune checkpoints.” Checkpoint blockade is predominantly achieved through the use of monoclonal
antibodies (“mAbs”) directed against the desired checkpoint protein (e.g., mAbs to PD1 or CTLA-4). These mAbs can block
the checkpoint proteins such as programmed cell death-1 (e.g., PD-1, Pembrolizumab/ Keytruda (Merck)) and CTLA-4 (e.g., Yervoy/Ipilimumab
(Bristol-Myers Squibb)), and hence reactivate the inhibited anti-cancer T cell responses and stimulate T cell proliferation. The
checkpoint inhibitors currently on the market have demonstrated significant and durable responses in some patients. However, immunotherapy
with checkpoint inhibitors is still limited by modest to low response rates. For example, 34% of advanced melanoma patients respond
to anti-PD-1 and 12% of advanced melanoma patients respond to anti-CTLA-4. To enhance the proportion of responding patients, strategies,
such as combinations with other existing cancer therapies, are currently being explored. While these strategies have promise, severe
side effects including potentially life threatening immune-related adverse events can affect upwards of 24% of patients using anti-CTLA-4
therapy alone, or 54% when used in combination with anti-PD-L1 therapy (e.g., Nivolumab).



An alternative approach to activate an immune response is through
the use of bi-specific antibodies that concomitantly engage the TCR on a T cell and an antigen on the tumor cell, examples of which
are BiTEs (e.g., Amgen) or Darts (e.g., Macrogenics). These bi-specific antibodies are distinct from the monoclonal antibodies
described above in that they are engineered to simultaneously bind to two different types of antigen, rather than one. To activate
the T cells, the bi-specific molecules are designed to engage a tumor antigen while also engaging a component of the T cell receptor,
called CD3. Since CD3 is expressed on all T cells, dual engagement through bi-specific molecules results in a global, non-specific
activation of T cells at the tumor or wherever the antigen is expressed. The non-specific activation of large T cell subsets can
give rise to significant toxicity, thereby significantly limiting the acceptable dose and therapeutic range of this approach.



An additional approach to activating an antitumor immune response
is cytokine immunotherapy. Cytokines, such as recombinant interleukin-2 (IL-2), can directly stimulate immune effector cells leading
to antitumor efficacy, but the clinical benefit with systemic administration is limited by induction of Tregs and by severe toxicities.
Recently, concepts for tumor-targeted delivery of IL-2 have shown promise. A Phase 1 trial data with an IL-2 molecule having multiple
releasable polyethylene glycol (PEG) chains, NKTR-214, is showing encouraging evidence of anti-tumor activity, and a favorable
tolerability profile. The PEGylation leads to a slow release of active IL-2 and loss of IL-2 preferential binding to Tregs. The
NKTR-214-induced immune cell changes promote immune cell tumor destruction, with increased numbers of proliferating CD8+ T cells
and NK cells in the blood and tumor and accumulation of CD8+ T cells relative to T regulatory immune suppressive cells in tumors.
A tumor-antigen-CEA-targeted IL-2 fusion protein also in phase I clinical testing, has been shown to increase natural killer and
CD8+ T cells in tumors. These data support the concept of immune cell-specific IL-2 delivery, such as in CUE biologics that include
IL-2 costimulatory molecules.



As described above, cancer cells can evade a normal immune response
by expressing cell surface inhibitory molecules that interact with and suppress the attacking T cells within the tumor microenvironment.
Consequently, more recent bi-specific approaches seek to decorate tumor cells with activating costimulatory signals to potentially
overcome tumor resident immune cell suppression. This is achieved by targeting a tumor antigen with one arm and presenting a costimulatory
signal for potential tumor resident T cell stimulation through the other. These bispecific molecules have been used in patients
with, in some cases, good therapeutic results. However, there are significant limitations. For example, they must first localize
to the tumor in order to exert their effects (e.g., those from Altor, Sutro, Covagen, Roche, and Amgen) and have the added limitation
of engaging only the subset of T cells which successfully traffic to the tumor within the treatment window. Notably, CUE biologics
are designed to engage T cells directly, not requiring tumor targeting, and thus allow for T cell priming and activation in the
periphery (e.g., tumor draining lymph node) outside the suppressive tumor microenvironment. Lastly, the use of these tumor directed
bi-specifics may be hampered by the drug’s short half life in patients, thus requiring continuous infusion.



5







A different approach that has shown some promise in tumor therapy
is to remove T cells from patients, activate and stimulate them outside the body (ex vivo), which expands them (usually over 7-14
days), and then infuse them back into the patients. These methods are termed cellular therapies, and include adoptive cell therapy
(“ACT”) and chimeric antigen receptor T cell (“CAR-T”) therapy (e.g., those from Juno and Kite). At the
outset, this is an individualized patient-specific approach. In ACT, native (un-modified) T cells are extracted and purified from
a patient, expanded ex vivo and re-introduced to the patient in order to increase the number of T cells available to kill the tumor
cell. Similarly, in CAR-T therapy, patient T cells are extracted and purified; however, distinct from ACT, patient T cells are
genetically modified to target tumor-specific antigens through the use of chimeric antigen receptors (“CARs”) prior
to patient infusion in an attempt to increase specificity. CARs are comprised of an external tumor-specific antibody fragment or
engineered TCR (e.g., Adaptimmune) linked to cytoplasmic signaling domains for T cell activation such that upon binding of the
tumor antigens, the engineered T cells proliferate and attack cancer cells.



CAR-T-based immunotherapy has demonstrated complete responses
of greater than 80% in recent clinical trials of acute lymphoblastic leukemia (“ALL”) patients. However, potent CAR-T
cell responses have produced life threatening cytokine release syndromes (“CRS”) in 69% of high burden ALL adults.
Severe toxicities and deaths led to a halt in JCAR015, Juno’s lead CAR-T program, and potentially pose a safety challenge
to the wider adoption of cellular therapies. Moreover, the technical requirements and expense associated with individualized T
cell extraction, ex vivo amplification/modification, and patient re-infusion represent significant scaling and cost challenges
that might limit broad usage and eventual commercialization of this therapeutic modality. Despite these safety and scalability
considerations, the recent demonstration of impressive clinical survival in patients treated with cellular therapies deserves serious
attention.



Our Approach for Next Generation Immunotherapies



We have developed a proprietary platform for the design and
development of biologic drugs for in vivo (e.g., directly in the patient’s body) T cell based immunotherapy. In the context
of cancer, CUE Biologics are being designed to selectively activate T cells which recognize cancer antigens (e.g., peptides) expressed
or amplified in cancer cells (tumor antigens or neoantigens). For the treatment of autoimmune diseases such as Type 1 diabetes,
celiac disease, arthritis and others, CUE Biologics are designed to selectively dampen disease-causing T cell responses directed
against self-antigens.



CUE Biologics are designed to mimic the signals, or “cues”,
of the immune system to generate highly focused T cell responses associated with disease. We accomplish this by the fusion of unique
costimulatory signaling molecules (ligands) with a TCR targeting p-MHC complex (“pMHC”). This co-engagement of signals
through the TCR and costimulatory receptor mimic and recapitulate the very signals delivered by APCs to T cells during an immune
response. In this way CUE BiologicsTM allow for the precise targeting of distinct signaling ligands exclusive to the T cell
population of interest, resulting in targeted T cell modulation.





CUE BiologicsTM are designed
to mimic Antigen Presenting Cells (“APCs”)



Our therapeutic approach is designed to be administered directly
in patients (in vivo) which differs markedly from other T cell therapeutic approaches such as ACT, which requires patients’
T cells to be first harvested, then stimulated and expanded outside the body before being reinfused in an activated state. We believe
CUE Biologics represent a breakthrough approach as a disease-specific biologic T cell modulator administered in vivo (in body)
rather than the ex vivo (outside the body) approach deployed by current cellular immune therapies. Furthermore, we believe the
desired pharmacological effect in patients will be more precisely controlled by directly administering CUE Biologics into the patient
for selective modulation of disease relevant T cells.



6







The therapeutic properties and selective nature of Cue Biopharma’s
drug candidates result from the design and optimization of key functional parameters for a given therapeutic framework. Each framework
harbors an MHC and one or more costimulatory element(s) optimized to drive a particular type of T cell response, such as stimulation
and expansion of a cytolytic T cell response to kill cancer cells, or specific down-regulation and inhibition in the context of
autoimmune disease. The targeting of the framework to specific T cell populations is dependent on the specific peptide linked to
the MHC. Notably, more than 75 peptides that are expressed by different solid tumors are currently described in the clinical literature.
Thus, after finalizing a therapeutic framework (pMHC-ligand-Fc) we believe different tumors can be addressed by changing the targeting
peptide, presenting the promise of greatly reducing the time and cost associated with the generation of new CUE molecules to take
forward through IND-enabling studies and, potentially, into the clinic.

targeting peptides to address different tumor types







Illustration of use of different
targeting peptides to address different indications



Using our CUE BiologicsTM platform, we believe we will
be able to design biologics that will have certain advantages over existing immunotherapies including increased specificity, reduced
toxicity and greater manufacturability. As such, we believe our approach to designing and developing immuno-modulatory biologics
represents a breakthrough, next-generation solution to realizing the promise of T cell based immunotherapies.



Competition



Immunotherapy technologies are advancing at a rapid pace and
we anticipate competing with companies developing bi-specific antibodies (e.g., Amgen, Inc., Hoffmann-La Roche (Roche), Sutro Biopharma),
CAR-T therapies (e.g., Novartis A.G., Juno Therapeutics, Kite Pharma, Inc.), checkpoint inhibitors (e.g., Bristol-Myers Squibb,
Merck & Co. and Pfizer, Inc.), antibody drug conjugates (“ADCs”) (e.g., Seattle Genetics, Inc., ImmunoGen, Inc.
and Sorrento Therapeutics), and targeted cytokines (Nektar/Bristol Myers Squibb, Roche) many of which have significantly greater
financial and other resources than we have.

CUE BiologicsTM Drug Candidates



The relative effectiveness of immunotherapies depends on whether
a relevant or optimal therapeutic mechanism to engage the immune system has been addressed by the therapy, and it is likely that
different immune stimulatory mechanisms will be required to optimally address certain cancers over others. The versatility of the
CUE BiologicsTM platform allows access to multiple distinct mechanisms with a series of biologic frameworks addressing a variety
of conditions and requirements. We have currently designed two promising therapeutic frameworks to support distinct and potent
mechanisms of T cell activation: our pMHC/IL-2 based CUE-100 series (to enhance overall numbers of tumor specific T cells) and
our pMHC/CD80:4-1BBL based CUE-200 series (to reinvigorate exhausted T cells). We expect to be able to target antigen-specific
T cell populations in a variety of indications by a simple peptide exchange into validated CUE BiologicsTM frameworks. We
continue to evaluate additional constructs from which we will launch further framework series in both oncology and autoimmunity.







Illustration of CUE-100 and CUE-200
frameworks CUE-101



In furtherance of our efforts to design and test various frameworks
addressing a variety of conditions, we are developing and implementing a complementary ex vivo (outside the body) human
cancer model assay system for testing and evaluating CUE BiologicsTM molecules directly in cancer patient-derived T cells.
The ex vivo assays have the potential to provide a powerful tool for demonstrating human translatability by evaluating preclinical
proof of mechanism and proof of concept directly in human samples, as well as for defining relevant metrics and critical parameters
informing clinical application(s). Through this assay system, we have recently tested various epitopes (CMV and MelanA/MART, shown
below) on the CUE-101 framework to support the versatility and robustness of our CUE BiologicsTM platform.

Results from CUE-100 human ex vivo
study, indicating treatment with CUE-100 (MelanA/MART) results in activation of antigen-specific T cells in healthy donors and
melanoma patients as measured by T cell expansion.



As exemplary of our CUE BiologicsTM platform, we have begun
development work on our anticipated first clinical candidate, CUE-101 (described below) and are utilizing our ex vivo assay capabilities
to generate data for proof of concept with potent, tumor antigen-selective T cell activation. The ex vivo assays, utilizing clinical
samples of peripheral blood mononuclear cells (“PBMCs”) for testing and evaluating CUE-101, are expected to provide
data to support an IND submission and to inform our phase I study protocol and clinical development strategy. Human PBMCs, including
those from cancer patients, are the most relevant model for characterizing the activity and specificity of CUE-101. These studies,
investigating the drug levels and duration of drug exposure, for functional and molecular changes (PD effects) in target immune
cells and in non-target cells will guide human dosing and PD biomarker monitoring in our phase I trial. In addition to providing
potentially insightful data relating to the prospects of antitumor efficacy in patients, the assays are designed to define the
drug exposure range for antitumor activity as well as provide evidence for clinical biomarker selection and the biopsy schedule
for clinical proof of mechanism.

CUE-101



Our current lead drug candidate, CUE-101, uses the pMHC/IL-2
CUE-100 framework, and is a fusion of a variant form of the cytokine Interleukin-2 (IL-2) and a T cell antigen (pMHC). The targeting
peptide contained in the pMHC that is currently used in CUE-101 is derived from the human papilloma virus E7 protein (HPV-E7).
CUE-101 is a single, covalently-assembled biologic designed to target and activate T cells specific to HPV-related cancers. Treatments
for patients with HPV-related cancers represent are an important unmet clinical need, which accounts for approximately 24,600 cases
of cervical, head and neck, and genitoanal cancers in the United States every year leading to approximately 9,000 deaths annually.
HPV-driven cancers lead to approximately 225,000 deaths worldwide each year. We believe our drug candidate CUE-101 has the potential
to provide patients with a more effective and safer alternative in treating their HPV-driven cancers.  It is our current intention
to file an IND for CUE-101 in the first quarter of 2019, provided the pre-IND efficacy and safety data generated supports continued
development.



Our preclinical data, including a mouse animal model of HPV+
cancer, have generated encouraging results with monotherapy treatment with a murine CUE biologic comprised of IL-2 costimulatory
and pMHC-HPV peptide domains. Tumor growth inhibition was observed with treatment in the HPV+ TC-1-Luc tumor model. Studies of
this agent in combination with an anti-PD-1 antibody resulted in complete tumor regression in some animals. These results compare
favorably to results achieved in the same preclinical study using IL-2 or anti-PD-1 therapy alone, where no regressions were observed.
Notably, in the tumor-free mice from the treatment group “cured” by the murine CUE:IL-2 compound combination with anti-PD-1
antibody, immunologic memory was demonstrated whereby no tumor growth observed in animals following tumor cell injection.







Results from CUE-101 human ex vivo study demonstrating peptide
selectivity in target T cell binding and engagement by comparing binding of CUE-101 versus CUE-100 (CMV) to disease specific HPV
E711-20CD8 human T cells.



We have profiled CUE-101 activity in tumor antigen-specific
T cells and PBMCs isolated from a healthy HPV+ human donor. These data demonstrate highly targeted engagement of CUE-101 specifically
to tumor antigen specific CD8+ T cells (shown above). These data further support that targeted engagement results in T cell receptor
and IL-2 receptor activation as measured by increases in receptor signaling molecules. Furthermore, CUE-101 induces antigen specific
T cell activation- and cytotoxic T lymphocyte (CTL)- cell surface marker changes and CTL-activity as measured by drug-induced production
of IFNg, an established marker of T cell activation and killing potential (shown below).
Lastly, CUE-101 has demonstrated expansion of antigen-specific T cells from donor PBMCs as a single agent. These results demonstrate
antigen-specific T cell activation and expansion with CUE-101 in human immune cells. The timing and magnitude of changes with drug
treatment will guide selection of the most relevant and robust markers and the timing for sampling in phase I patients treated
with CUE-101.

Results from CUE-101 human ex vivo study indicating treatment
with CUE-101 (HPV-E7) results in highly specific activation of antigen-specific T cells in a peptide and MOD (IL-2) dependent manner
as measured by interferon gamma release,



While this preclinical data from ex vivo analysis of
human T cells is highly encouraging, the data represent a single healthy HPV+ subject and may not be representative of results
in samples from patients with HPV+ driven malignancies. As described below under “Business — Background,”
cancer uses various mechanisms to suppress and alter the immune system. For example, it has been observed from clinical studies
that some cancers, including HPV+ cancers, are capable of reducing and altering T cell populations. Therefore, we intend to further
study CUE-101 in ex vivo assays with blood derived from multiple HPV+ cancer patients to demonstrate activation and proliferation
of HPV-E7 specific T cells. We will also continue to survey other drug constructs targeting various cancer epitopes and plan to
select promising candidates for clinical development. It is our current intention to file an IND for CUE-101 by the first quarter
of 2019, provided the pre-IND efficacy and safety data generated supports continued development.







Results from CUE-101 human ex vivo
study, indicating treatment with CUE-101 results in expansion of antigen-specific T cells as a single agent



While CUE-101 targets the HPV-E7 TCR in cervical/head and neck
cancers, we believe our CUE BiologicsTM platform may be used to target a large variety of alternative peptides which may allow
us to address many tumors with high therapeutic need in the oncology patient population. In support of this, we have recently demonstrated
highly potent efficacy in preclinical murine models targeting non-viral epitopes. These data together with the recent human ex
vivo experiments using a melanoma specific epitope (MelanA/MART, shown above) in both healthy donor and melanoma patient samples
support CUE-100 framework’s ability to activate distinct T cell populations via a simple amino acid peptide antigen exchange
on an otherwise validated scaffold, which should reduce the time to clinic (and associated costs) of next-generation biologics.
We are currently exploring multiple unique epitopes in the context of the CUE-100 series framework in human ex vivo assays to help
guide prioritization of programs.



11







Extension to Autoimmune Indications



In addition to oncology, we are expanding our technology’s
reach to generate highly promising and novel immunotherapeutics for the treatment of debilitating autoimmune disorders. Autoimmune
indications may be addressed with our technology through two general strategies: (1) depleting disease causing autoreactive T cells
by selectively delivering inhibitory signals or (2) by delivering signals to induce and expand regulatory T cells, which subsequently
act to inhibit disease-causing T cells.



CUE BiologicsTM frameworks for autoimmune disease will
be designed to influence a subset of T cells known as CD4 T cells. CD4 T cells recognize peptides in the context of MHC class II
proteins. Therefore, prototypic CUE BiologicsTM frameworks in autoimmunity would rely on MHC class II recognition by CD4 T
cells. This is distinct from the MHC class I recognition by CD8 T cells that is the basis of our current oncology pipeline. Both
pathogenic (i.e., disease causing) and regulatory (disease limiting) CD4 T cell subsets are known to exist in autoimmune disease.
Our CUE BiologicsTM frameworks in autoimmunity will therefore be intended to treat autoimmune diseases by either depleting
pathogenic CD4 T cells or amplifying regulatory CD4 T cell responses to specific disease relevant antigens. Potential autoimmune
indications of interest include Type 1 diabetes, arthritis, autoimmune thyroiditis (e.g., Graves’ disease), celiac disease
and CNS/neurological autoimmune disorders (e.g., multiple sclerosis, Parkinson’s disease, etc.).



Consistent with our plan to establish strategic partnerships
with leading pharmaceutical or biotechnology organizations to further our development efforts, in November 2017 we entered into
a Collaboration Agreement with Merck Sharp & Dohme Corp. (“Merck”) for a partnership to research and develop certain
of our proprietary biologics that target certain autoimmune diseases. We view this Collaboration Agreement as a component of our
development strategy since it will allow us to advance our autoimmune programs in partnership with a world class pharmaceutical
company, while also continuing our focus on our more advanced cancer programs. For further information, see below “Business — Our
Collaboration Agreement with Merck”.





MODTM and viraTopeTM Technology Platforms



Supporting our CUE BiologicsTM platform are two companion
discovery platforms: MODTM, a costimulatory optimization and discovery platform, and viraTopeTM, a T cell epitope discovery
platform, both illustrated below.



12











The design of CUE BiologicsTM
allows for incorporation of antigens and costimulatory molecules discovered through the MODTM platform to develop novel
biologics to address new indications in oncology and autoimmune disorders.



We believe that the MODTM technology platform has a unique
ability to optimize existing costimulatory ligands for use in our biologics as well as discover as yet unknown costimulatory signaling
molecules. The MODTM platform represents a high throughput method for determining specific cell surface protein-protein interactions
(e.g., signaling receptor:ligand pair(s)). In brief, MODTM allows for the detection of associations between distinct cell
surface query proteins (i.e., ligands) and cell surface expression libraries (i.e., receptors) to first identify molecular engagements
and further allows for the mechanistic dissection of complex biochemical function by screening large numbers of mutant molecules.
Taken together, we believe that MODTM can provide powerful tools to first define novel protein-protein interactions associated
with T cell activation. Secondly, MODTM is designed to allow us to modulate these signaling ligands through the rapid screening
of mutants in order to dissect biochemical function and alter binding properties (i.e., altered affinities and specificities).
A key component of our therapeutic design involves decreasing the binding of the costimulatory element while retaining its biological
activity (i.e., affinity attenuation). Affinity attenuation allows the pMHC to drive the engagement with the target T cells and
limits off-target engagement and associated collateral toxicity.



The viraTopeTM platform addresses the historic difficulty
of identifying disease associated T cell signatures through the monitoring of complex T cell repertoires. As discussed previously,
at the core of the molecular events comprising a T cell-mediated immune response is the engagement of the T cell receptor (“TCR”)
with a small peptide antigen presented by an MHC molecule, referred to as a T cell epitope. This represents the immune system’s
targeting mechanism and is a requisite molecular interaction for T cell activation and function, and forms the basis of our targeted
immunotherapeutics (i.e., TCR targeting). The viraTope platform is designed to achieve rapid, comprehensive, and quantitative immunomonitoring
by interrogating primary T cells with a combinatorial library of pMHC in conjunction with deep sequencing. viraTope’sTM
libraries would query T cells with all possible mimotopes, leaving cognate pMHC bound to their respective T cells. Deep sequencing
of the bound pMHC would comprehensively enumerate all T cell epitopes recognized by a given T cell sample. In this way, viraTopeTM
could allow the identification of novel epitopes differentially represented in diseased versus control patients and would further
make the frequencies of all known and unknown T cell specificities accessible for prospective, in-study, and retrospective analyses
of clinical trials. Thus, the ability to systematically identify the entire ensemble of epitopes for a given disease state represents
a unique opportunity for the development of diagnostics and highly targeted therapeutics against infectious diseases, autoimmunity
and cancers. We believe that viraTopeTM has the ability to comprehensively and quantitatively monitor T cell responses, which
could lead to the discovery of novel drug candidates and biomarkers for internal use or to potentially license to strategic partners.



Our Business Strategy



Our primary objective is to become a leading, next-generation
immunotherapeutics/biopharmaceutical company developing highly highly selective biologics for precision immune modulation. We plan
to do this through coordinated and integrated strategic initiatives. Key elements of our strategy include:



13







| | · | Modular and versatile platform allowing for efficient and rapid drug design, prototyping and optimization.   We
plan to leverage our CUE BiologicsTM platform’s modular capabilities to rapidly and efficiently develop our drug candidates.
We believe our platform will provide a highly productive portfolio of promising clinical drug candidates aimed at specifically
targeting disease relevant T cells for effective immune modulation. The modular design of our CUE BiologicsTM platform provides
the flexibility and versatility to construct drug frameworks comprised of various MOD combinations to elicit novel mechanisms of
action. As described above under “Our Approach to Next Generation Immunotherapies,” after we establish a successful
framework that uses a specific peptide to target a particular disease indication, we expect to be able to use that framework to
target additional disease indications by changing the targeting peptide. Therefore, by leveraging the previous work done to establish
a framework, we believe we will be able to significantly compress the timeline (by as much as six to twelve months) and capital
requirements associated with the development of additional drug candidates.

| | · | Using preclinical data and efficient Phase I clinical study design to accelerate the development process.   We
recently demonstrated through ex vivo assays using human clinical samples that CUE:IL-2 activates T cells in an antigen specific
manner. We plan to continue testing our biologic drug constructs in ex vivo studies with human clinical samples using various cancer
relevant epitopes to demonstrate selective activation of T cells specific for various antigens spanning a range of oncology indications.
We believe this approach provides meaningful validating data enhancing the quality of our preclinical data package for IND filing.
This data also has the potential of increasing the probability for identifying relevant pharmacodynamic (“PD”) biomarkers
for patient monitoring and as a potential surrogate marker of anti-tumor activity in the clinical setting. Furthermore, we believe
these ex vivo studies will supplement and potentially reduce our reliance on preclinical animal models, providing a more cost and
time efficient means of testing our drug candidates’ activities. Given the urgent medical needs we intend to address with
our drug candidates, we are planning to design and conduct our Phase I clinical studies to generate safety data and a clinically
meaningful data package around efficacy with the aim of approaching the FDA for an accelerated registration study.

| | · | Using our process development and protein biochemistry capabilities as a competitive advantage.   We
anticipate devoting significant resources to optimizing drug design and process development, including protein engineering and
optimization, which are key components to maximizing the value of our current and future drug candidates. Through our core competencies
and proprietary CUE BiologicsTM, MODTM and viraTopeTM technology platforms, we are designing and developing a growing
intellectual property portfolio of novel and proprietary immune modulatory biologics. We believe our modular approach to designing
biologics, coupled with the protein engineering and optimization capabilities offered by our platform technologies, should enable
us to more rapidly and cost-effectively design and optimize potential drug candidates, as compared to more traditional preclinical
development processes. Although we have yet to advance any of our drug candidates into the clinic, we believe this efficient preclinical
development process positions us well to potentially establish a leading position in the discovery and development of promising
next generation immunotherapies.

| | · | Establishing key strategic partnerships with leading pharmaceutical companies.   We believe that
our CUE BiologicsTM platform offers the promise of enabling us to develop multiple drug candidates that address a variety
of potential indications within oncology, autoimmune disease and infectious disease. Accordingly, as we continue to evolve and
progress our drug candidates through preclinical and early clinical development, we plan to establish strategic partnerships with
leading pharmaceutical or biotechnology organizations, such as our partnership with Merck pursuant to the Collaboration Agreement
described below. We believe that this will allow us to further enhance our capabilities and capacities to discover and develop
multiple, promising drug candidates for unmet medical needs in oncology and autoimmunity in a highly productive and cost-effective
manner.

If we fail to meet any of the Diligence Milestones, Einstein
will have the right to terminate the Einstein License if such Diligence Milestone is not satisfied within thirty (30) days from
receiving a written notice of default from Einstein. Under certain circumstances and upon prior notice to Einstein, we may have
the right to an additional extension of our Diligence Milestones if, despite our commercially reasonable efforts we are not able
to satisfy the Phase II clinical trial Diligence Milestone or any subsequent Diligence Milestone. As of the date of this prospectus,
we have met all required Diligence Milestones.



Our Collaboration Agreement with Merck



On November 14, 2017, we entered into an Exclusive Patent License
and Research Collaboration Agreement (the “Collaboration Agreement”) with Merck Sharp & Dohme Corp. (“Merck”)
for a partnership to research and develop certain of our proprietary biologics that target certain autoimmune disease indications
(the “Initial Indications”). We view this Collaboration Agreement as a component of our development strategy since
it will allow us to advance our autoimmune programs in partnership with a world class pharmaceutical company, while also continuing
our focus on our more advanced cancer programs. The research program outlined in the Collaboration Agreement entails (1) our research,
discovery and development of certain CUE BiologicsTM drug candidates up to the point of demonstration of certain biologically
relevant effects (“Proof of Mechanism”) and (2) the further development by Merck of the CUE BiologicsTM drug candidates
that have demonstrated Proof of Mechanism (the “Proposed Product Candidates”) up to the point of demonstration of all
or substantially all of the properties outlined in such Proposed Product Candidates’ profiles as described in the Collaboration
Agreement.



For the purposes of this collaboration, we have granted to Merck
under the Collaboration Agreement an exclusive license under certain of our patent rights, including a sublicense of patent rights
licensed from Einstein, to the extent applicable to the specific CUE BiologicsTM that are elected to be developed by Merck.
From the effective date of the Collaboration Agreement until the earlier of (i) the first achievement of Proof of Mechanism for
a Cue BiologicTM drug candidate or (ii) 18 months after we notify the joint steering committee that the first Product Candidate
has been synthesized under the research program, we are required to forebear from researching, developing or licensing to a third
party rights related to any CUE BiologicsTM drug candidate for the treatment of autoimmune diseases other than pursuant to
the Collaboration Agreement. In addition, so long as Merck continues product development on a Proposed Product Candidate, we are
restricted from conducting any development activities within the Initial Indication covered by such Proposed Product Candidate
other than pursuant to the Collaboration Agreement. The Company is not required to forbear at any time, however, from developing
other Cue BiologicsTM for use in therapeutic areas other than autoimmune diseases, e.g., for use in treating cancer or infectious
diseases.



16







In exchange for the licenses and other rights granted to Merck
under the Collaboration Agreement, we received a $2.5 million nonrefundable up-front payment and may be eligible to receive additional
funding in developmental milestone payments, as well as tiered royalties if all research, development, regulatory and commercial
milestones agreed upon by both parties are successfully achieved. Excluding the upfront payment described above, we are eligible
to earn up to $101 million for the achievement of certain research and development milestones, $120 million for the achievement
of certain regulatory milestones and $150 million for the achievement of certain commercial milestones, in addition to tiered royalties
on sales, if all pre-specified milestones associated with multiple products across the primary disease indication areas are achieved.
The Collaboration Agreement requires us to use the first $2.7 million of milestone payments we receive under the agreement to fund
contract research. The amount of the royalty payments is a percentage of product sales ranging in the single digits based on the
amount of such sales.



The term of the Collaboration Agreement extends until the expiration
of all royalty obligations following a product candidate’s receipt of marketing authorization, at which point Merck’s
licenses and sublicenses granted under the agreement shall become fully paid-up, perpetual licenses and sublicenses, as applicable.
Royalties on each product subject to the Collaboration Agreement shall continue on a country-by-country basis until the expiration
of the later of: (1) the last-to-expire patent claiming the compound on which such product is based and (2) a period of ten years
after the first commercial sale of such product in such country.



Notwithstanding the foregoing, Merck may terminate the Collaboration
Agreement at any time upon 30 days’ notice to the Company. The Collaboration Agreement may also be terminated by either party
if the other party is in breach of its obligations thereunder and fails to cure such breach within 90 days after notice or by either
party if the other party files for bankruptcy or other similar insolvency proceedings.



Our Intellectual Property



We believe that our current patent applications and any future
patents and other proprietary rights that we own, or control through licensing, are and will be essential to our business. We believe
that these intellectual property rights will affect our ability to compete effectively with others. We also rely and will rely
on trade secrets, know-how, continuing technological innovations and licensing opportunities to develop, maintain and strengthen
our competitive position. We seek to protect these, in part, through confidentiality agreements with certain employees, consultants,
advisors and other parties. Our success will depend in part on our ability, and the ability of our licensor, to obtain, maintain
(including making periodic filings and payments) and enforce patent protection for our/their intellectual property, including those
patent applications to which we have secured exclusive rights.



We own or have licensed 14 pending patent applications in the
United States (including 11 pending U.S. provisional patent applications), four pending international PCT applications and 34 pending
foreign patent applications intended to protect the intellectual property underlying our technology. Our patent applications describe
certain features of our technologies, including our CUE BiologicsTM platform and drug candidates, viraTopeTM, MODTM
screening, MODTM variants and combinations of MODs. We plan to spend considerable resources and focus in the future on obtaining
U.S. and foreign patents. We have and will continue to actively protect our intellectual property. No assurances can be given that
any of our patent applications will result in the issuance of a patent or that the examination process will not require us to narrow
our claims. In addition, any issued patents may be contested, circumvented, found unenforceable or invalid, and we may not be able
to successfully enforce our patent rights against third parties. No assurance can be given that others will not independently develop
a similar or competing technology or design around any patents that may be issued to us. We intend to expand our international
operations in the future and our patent portfolio, copyright, trademark and trade secret protections may not be available or may
be limited in foreign countries.



Each of our patents, if and when granted, will generally have
a term of 20 years from its respective priority filing date, subject to available extensions. They are thus set to expire no earlier
than dates ranging from 2032 to 2037, although there can be no assurance that any of the patent application will be granted.



17







Target Markets



Our initial focus and objective is to develop drug candidates
for cervical/head and neck cancers, hepatocellular carcinomas, and melanoma. We expect that our future developmental roadmap will
also focus on new drug candidates that target autoimmune disorders. We currently do not have any products that are developed such
that they can be tested for clinical trials or commercial use. According to published reports, in 2016 oncology drugs were an $87.5
billion global market and autoimmune drugs constituted a $47.8 billion global market.



Our Commercialization Strategy



We are a preclinical stage company without a history of revenue
or manufacturing, late stage clinical development or marketing experience. Because late stage clinical development, as well as
establishing a full manufacturing and distribution structure, is expensive and time consuming, we intend to explore alternative
commercialization strategies, including:



| | · | developing drug candidates through the earlier stages of clinical development with the objectives of rapid, cost effective
risk reduction and value creation and then establishing strategic partnership for late stage clinical development and subsequent
commercialization;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | developing a robust pipeline of promising drug candidates at various stages of the development process to establish optionality
and regular value inflection opportunities and revenue(s);
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | strategically entering into co-development partnership(s) to retain potential for commercialization rights on selected drug
candidate(s) and market opportunities; and
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | partnering with industry participants to incorporate our technology into new and existing drugs.
| | - | ------------------------------------------------------------------------------------------------



We expect that partnering with pharmaceutical or biotherapeutic
companies may accelerate product acceptance into our target market areas and gain the sales and marketing advantages of the partner’s
distribution infrastructure. We intend to continue to strengthen our market position and solidify our leadership position in immunotherapy
by continuing to improve our technology, broadening our clinical and therapeutic applications, identifying new clinical and therapeutic
applications and forming strategic partnerships.



Government Regulation and Product Approval



Therapeutic products are subject to rigorous regulation by the
U.S. Food and Drug Administration (the “FDA”) and other governmental agency regulations in the United States and in
foreign countries. Noncompliance with applicable requirements can result in import detentions, fines, civil penalties, injunctions,
suspensions or losses of regulatory approvals or clearances, recall or seizure of products, operating restrictions, denial of export
applications, governmental prohibitions on entering into supply contracts, and criminal prosecution. Failure to obtain regulatory
approvals or the restriction, suspension or revocation of regulatory approvals or clearances, as well as any other failure to comply
with regulatory requirements, would have a material adverse effect on our business, financial condition and results of operations.
In connection with therapeutic approval, we will have to comply with the many requirements associated with preclinical and clinical
trials, the FDA application process, the terms of any pre-certification protocols and agreements, FDA manufacturing requirements
for prototypes, and testing. Upon approval of a Biologics License Application (“BLA”) and similar approvals in other
jurisdictions, there will be additional regulation relating to the packaging, distribution, marking, marketing and claims of our
potential products. These later regulations are not only found in federal regulation but many states and, of course, foreign countries.



The FDA Process



The FDA regulates the clinical testing and design of therapeutics
to ensure that medical products distributed in the United States are safe and effective for their intended uses. The application
process for a new therapeutic is highly regulated.



As a biopharmaceutical company that operates in the United States,
we are subject to extensive regulation. Our potential products will be regulated as biologics. With this classification, commercial
production of our potential products will need to occur in registered and licensed facilities in compliance with current good manufacturing
procedures (“cGMP”) established by the FDA for biologics. The FDA categorizes human cell- or tissue-based products
as either minimally manipulated or more than minimally manipulated, and has determined that more than minimally manipulated products
require clinical trials to demonstrate product safety and efficacy and the submission of a BLA for marketing authorization.



18







Government authorities in the United States (at the federal,
state and local levels) and in other countries extensively regulate, among other things, the research, development, testing, manufacturing,
quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring
and reporting, marketing and export and import of biopharmaceutical products such as those we are developing. Our drug candidates
must be approved by the FDA before they may be legally marketed in the United States and by the appropriate foreign regulatory
agency before they may be legally marketed in a foreign country. Generally, our activities in other countries will be subject to
regulation that is similar in nature and scope as that imposed in the United States, although there can be important differences.
Additionally, some significant aspects of regulation in Europe are addressed in a centralized way, but country-specific regulation
remains essential in many respects. The process for obtaining regulatory marketing approvals and the subsequent compliance with
appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial
resources.



U.S. Product Development Process



In the United States, the FDA regulates pharmaceutical and biological
products under the Federal Food, Drug and Cosmetic Act (the “FDCA”), the Public Health Services Act (the “PHSA”)
and implementing regulations. Products are also subject to other federal, state and local statutes and regulations. The process
of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and
regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements
at any time during the product development process, approval process or after approval, may subject an applicant to administrative
or judicial sanctions. FDA sanctions could include, among other actions, refusal to approve pending applications, withdrawal of
an approval, a clinical hold, warning letters, product recalls or withdrawals from the market, product seizures, total or partial
suspension of production or distribution injunctions, fines, refusals of government contracts, restitution, disgorgement or civil
or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. The FDA has limited
experience with commercial development of T cell therapies for cancer. The process required by the FDA before a biological product
may be marketed in the United States generally involves the following:



| | · | completion of nonclinical laboratory tests and animal studies according to Good Laboratory Practices (“GLPs”) and
applicable requirements for the humane use of laboratory animals or other applicable regulations;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | submission to the FDA of an Investigational New Drug Application (an “IND”), which must become effective before
human clinical trials may begin;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------



| | · | performance of adequate and well-controlled human clinical trials according to the FDA’s regulations commonly referred
to as Good Clinical Practices (“GCPs”), and any additional requirements for the protection of human research patients
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 BLA for marketing approval 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 Marketing Practices (“cGMP”) to assure that the facilities, methods and controls
are adequate to preserve the biological product’s identity, strength, quality and purity and, if applicable, the FDA’s
current Good Tissue Practices (“cGTPs”) for the use of human cellular and tissue products;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | potential FDA audit of the nonclinical study and clinical trial sites that generated the data in support of the BLA; and
| | - | ------------------------------------------------------------------------------------------------------------------------



| | · | FDA review and approval, or licensure, of the BLA.
| | - | --------------------------------------------------



19







Before testing any biological drug candidate, including our
drug candidates, in humans, the drug candidate enters the preclinical testing stage. Preclinical tests, also referred to as nonclinical
studies, include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the
potential safety and activity of the drug candidate. The conduct of the preclinical tests must comply with federal regulations
and requirements, including GLPs. The clinical trial sponsor must submit the results of the preclinical 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 preclinical testing may continue even after the IND is submitted. The IND automatically becomes effective 30 days
after receipt by the FDA, unless the FDA raises concerns or questions regarding the proposed clinical trials and places the 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 on a biological drug candidate 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. Accordingly, we cannot be sure that submission of an
IND will result in the FDA allowing clinical trials to begin or that, once begun, issues will not arise that suspend or terminate
such trials.



Clinical trials involve the administration of the biological
drug 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. Clinical trials must be
conducted and monitored in accordance with the FDA’s regulations comprising the GCP requirements, including the requirement
that all research patients provide informed consent. Further, each clinical trial must be reviewed and approved by an independent
institutional review board (an “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. Clinical trials also must be reviewed by an institutional biosafety
committee (an “IBC”), a local institutional committee that reviews and oversees basic and clinical research conducted
at that institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment.



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



| | · | Phase 1. The biological product is initially introduced into human subjects to test for safety (adverse effects),
determine recommended Phase 2 dosing and evaluate any signals of efficacy for specific targeted diseases. The initial human testing
is often conducted in patients, rather than in healthy volunteers, in the case of products for severe or life-threatening diseases,
especially when the product is inherently toxic.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Phase 2. The biological product is evaluated in a limited patient population to identify safety risks, optimize
dosing and preliminarily evaluate the efficacy of the product for specific targeted diseases.
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Phase 3. Clinical trials are undertaken in an expanded patient population at geographically dispersed clinical
trial sites to further evaluate dosage, clinical efficacy, potency, and safety. These clinical trials are intended to establish
the overall risk to benefit ratio of the product and provide an adequate basis for product labeling.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Post-approval clinical trials, sometimes referred to as Phase
4 clinical trials, may be conducted after initial marketing approval. These clinical trials are used to gain additional experience
from the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow-up.



During all phases of clinical development, regulatory agencies
require extensive monitoring and auditing of all clinical activities, clinical data, and clinical trial investigators. Annual progress
reports detailing the results of the clinical trials must be submitted to the FDA. Written IND safety reports must be promptly
submitted to the FDA, the National Institutes of Health and the investigators for serious and unexpected adverse events, as well
as any findings from other studies, tests in laboratory animals or in vitro testing that suggest a significant risk for human patients,
or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator
brochure. The sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that the information
qualifies for reporting. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction
within seven calendar days after the sponsor’s initial receipt of the information. Phase 1, Phase 2 and Phase 3 clinical
trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor or its data safety monitoring
board may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research patients
are being exposed to an unacceptable health risk, including risks inferred from other unrelated immunotherapy trials. Similarly,
an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in
accordance with the IRB’s requirements or if the biological product has been associated with unexpected serious harm to patients.



20







Human immunotherapy products are a new category of therapeutics.
Because this is a relatively new and expanding area of novel therapeutic interventions, there can be no assurance as to the length
of the trial period, the number of patients the FDA will require to be enrolled in the trials in order to establish the safety,
efficacy, purity and potency of immunotherapy products, or that the data generated in these trials will be acceptable to the FDA
to support marketing approval.



Concurrently with clinical trials, companies usually complete
additional studies and must also develop additional information about the physical characteristics of the biological product 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 PHSA 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 drug 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 drug candidate does not undergo
unacceptable deterioration over its shelf life.



U.S. Review and Approval Processes



After the completion of clinical trials of a biological product,
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 studies, human trials, information on the manufacture and composition of the product, proposed
labeling and other relevant information. The FDA may grant deferrals for submission of data or full or partial waivers. The testing
and approval processes require substantial time and effort and there can be no assurance that the FDA will accept the BLA for filing
and, even if filed, that any approval will be granted on a timely basis, if at all.



Under the Prescription Drug User Fee Act, as amended (the “PDUFA”),
each BLA must be accompanied by a significant user fee. The FDA adjusts the PDUFA user fees on an annual basis. PDUFA also imposes
an annual product fee for biological products and an annual establishment fee on facilities used to manufacture prescription biological
products. 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 reviews the BLA to determine, among other things, whether the proposed product is safe, potent, and/or effective
for its intended use, and has an acceptable purity profile, and whether the product is being manufactured in accordance with cGMP
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 product.
If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS. The FDA will not approve a BLA without
a REMS, if required.



21







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. For immunotherapy products, the FDA also will not approve the product if the manufacturer is not in compliance
with the cGTPs, to the extent applicable. These are FDA regulations and guidance documents that govern the methods used in, and
the facilities and controls used for, the manufacture of human cells, tissues, and cellular and tissue based products (“HCT/Ps”),
which are human cells or tissue intended for implantation, transplant, infusion, or transfer into a human recipient. The primary
intent of the cGTP requirements is to ensure that cellular tissue based products are manufactured in a manner designed to prevent
the introduction, transmission and spread of communicable disease. FDA regulations also require tissue establishments to register
and list their HCT/Ps with the FDA and, when applicable, to evaluate donors through screening and testing. 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. To assure cGMP, cGTP and GCP compliance, an applicant must incur significant
expenditure of time, money and effort in the areas of training, record keeping, production, and quality control.



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. Data obtained
from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data. If the
agency decides not to approve the BLA in its present form, the FDA will issue a complete response letter that 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 risk management plan, 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.



In addition, under the Pediatric Research Equity Act (the “PREA”),
a BLA or supplement to a BLA must contain data to assess the safety and effectiveness of the product for the claimed indications
in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the
product is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers. Unless otherwise
required by regulation, the PREA does not apply to any product for an indication for which orphan designation has been granted.
However, if only one indication for a product has orphan designation, a pediatric assessment may still be required for any applications
to market that same product for the non-orphan indication(s).



Expedited Development and Review Programs



The FDA has various programs, including Fast Track, Breakthrough
Therapy Designation, priority review, and accelerated approval, which are intended to expedite or simplify the process for reviewing
products, and/or provide for approval on the basis of surrogate endpoints. Even if a product qualifies for one or more of these
programs, the FDA may later decide that the product no longer meets the conditions for qualification or that the time period for
FDA review or approval will not be shortened. Generally, products that may be eligible for these programs are those for serious
or life-threatening conditions, those with the potential to address unmet medical needs, and those that offer meaningful benefits
over existing treatments. For example, Fast Track is a process designed to facilitate the development and expedite the review of
products to treat serious diseases and fill an unmet medical need. The request may be made at the time of IND submission and generally
no later than the pre-BLA or pre-NDA meeting. The FDA will respond within 60 calendar days of receipt of the request. Breakthrough
Therapy Designation is available for products that are intended to treat a serious condition where preliminary clinical evidence
indicates that the product may demonstrate substantial improvement on a clinically significant endpoint(s) over available therapies.
The request may be made at the time of IND submission and generally no later than the end-of-Phase 2 meeting. The FDA will respond
within 60 calendar days of receipt of the request. Breakthrough Therapy Designation conveys all of the Fast Track program features
along with more intensive FDA guidance and interaction and eligibility for rolling review and priority review. Priority review,
which is requested at the time of BLA or NDA submission, is designed to give products that offer major advances in treatment or
provide a treatment where no adequate therapy exists an initial review within six months as compared to a standard review time
of ten months. Although Fast Track, Breakthrough Therapy Designation and priority review do not affect the standards for approval,
the FDA will attempt to expedite review of the application. Accelerated approval provides an earlier approval of products to treat
serious diseases, and that fill an unmet medical need based on a surrogate endpoint, which is a laboratory measurement or physical
sign used as an indirect or substitute measurement representing a clinically meaningful outcome. Discussions with the FDA about
the feasibility of an accelerated approval typically begin early in the development of the product in order to identify, among
other things, an appropriate endpoint. As a condition of approval, the FDA may require that a sponsor of a product receiving accelerated
approval perform adequate and well-controlled post-marketing clinical trials.



22







Orphan Drug Designation and Exclusivity



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



If a product that has orphan drug designation subsequently receives
the first FDA approval for the disease for which it has such designation, the product is entitled to seven years of orphan product
exclusivity. During the seven-year exclusivity period, the FDA may not approve any other applications to market a product containing
the same active moiety for the same disease, except in very limited circumstances, such as a showing of clinical superiority to
the product with orphan drug exclusivity. A product is clinically superior if it is safer, more effective or makes a major contribution
to patient care. Thus, orphan drug exclusivity could block the approval of one of our potential products for seven years if a competitor
obtains approval of the same product as defined by the FDA and we are not able to show the clinical superiority of our product
candidate or if our product candidate’s indication is determined to be contained within the competitor’s product orphan
indication. In addition, the FDA will not recognize orphan drug exclusivity if a sponsor fails to demonstrate upon approval that
the product is clinically superior to a previously approved product containing the same active moiety for the same orphan condition,
regardless of whether or not the approved product was designated an orphan drug or had orphan drug exclusivity.



Post-Approval Requirements



Any potential products for which we receive FDA approvals are
subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences
with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements,
and complying with FDA promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising,
restrictions on promoting products for uses or in patient populations that are not described in the product’s approved uses
(known as “off-label use”), limitations on industry-sponsored scientific and educational activities, and requirements
for promotional activities involving the internet. Although physicians may prescribe legally available products for off-label uses,
if the physicians deem to be appropriate in their professional medical judgment, it is FDA’s position that manufacturers
may not market or promote such off-label uses.



In addition, quality control and manufacturing procedures must
continue to conform to applicable manufacturing requirements after approval to ensure the quality and long-term stability of the
product. We expect to rely on third parties for the production of clinical and commercial quantities of our potential products
in accordance with cGMP regulations. cGMP regulations require among other things, quality control and quality assurance as well
as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from
cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved 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 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. Discovery of problems with a product after
approval may result in restrictions on a product, manufacturer, or holder of an approved BLA, including, among other things, recall
or withdrawal of the product from the market. In addition, changes to the manufacturing process are strictly regulated, and depending
on the significance of the change, may require prior FDA approval before being implemented. Other types of changes to the approved
product, such as adding new indications and claims, are also subject to further FDA review and approval.



23







The FDA also may require post-marketing testing, known as Phase
4 testing, and surveillance to monitor the effects of an approved product. Discovery of previously unknown problems with a product
or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial
or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors, and
civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a
product’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation
of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established,
or the FDA’s policies may change, which could delay or prevent regulatory approval of our potential products under development.



U.S. Patent Term Restoration and Marketing Exclusivity



The Biologics Price Competition and Innovation Act (the “BPCIA”)
amended the PHSA to authorize the FDA to approve similar versions of innovative biologics, commonly known as biosimilars. A competitor
seeking approval of a biosimilar must file an application to establish its molecule as highly similar to an approved innovator
biologic, among other requirements. The BPCIA, however, bars the FDA from approving biosimilar applications for 12 years after
an innovator biological product receives initial marketing approval. This 12-year period of data exclusivity may be extended by
six months, for a total of 12.5 years, if the FDA requests that the innovator company conduct pediatric clinical investigations
of the product.



Depending upon the timing, duration and specifics of the FDA
approval of the use of our drug candidates, some of our U.S. patents, if granted, may be eligible for limited patent term extension
under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Act. The Hatch-Waxman
Act permits a patent restoration term of up to five years, as compensation for patent term lost during product development and
the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total
of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the
effective date of an IND and the submission date of a BLA plus the time between the submission date of a BLA and the approval of
that application. Only one patent applicable to an approved product is eligible for the extension and the application for the extension
must be submitted prior to the expiration of the patent. The U.S. Patent and Trademark Office, in consultation with the FDA, reviews
and approves the application for any patent term extension or restoration. In the future, we may apply for restoration of patent
term for one of our currently owned or licensed patent applications, if granted, to add patent life beyond its current expiration
date, depending on the expected length of the clinical trials and other factors involved in the filing of the relevant BLA.



Pediatric exclusivity is another type of regulatory 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.



Employees



As of December 31, 2017, we had 28 full-time employees and two
part-time employees. Substantially all of our employees are in Cambridge, Massachusetts. None of our employees are represented
by a labor union or covered by a collective bargaining agreement, and we believe our relationship with our employees is good. Additionally,
we utilize independent contractors and other third parties to assist with various aspects of our drug and product development.

Item 1A. Risk Factors



We are subject to various risks that may materially harm our
business, prospects, financial condition and results of operations. This discussion highlights some of the risks that may affect
future operating results. These are the risks and uncertainties we believe are most important for you to consider. We cannot be
certain that we will successfully address these risks. If we are unable to address these risks, our business may not grow, our
stock price may suffer and we may be unable to stay in business. Additional risks and uncertainties not presently known to us,
which we currently deem immaterial or which are similar to those faced by other companies in our industry or business in general,
may also impair our business, prospects, results of operations and financial condition. The risks discussed below include forward-looking
statements, and our actual results may differ substantially from those discussed in these forward-looking statements.



Risks Related to Our Business



We are a preclinical stage biopharmaceutical
company, have no history of generating revenue, have a history of operating losses, and we may never achieve or maintain profitability.





We are a preclinical stage biopharmaceutical company. We have
a limited operating history and only a preliminary business plan upon which investors may evaluate our prospects. We have never
generated revenues and have a history of losses from operations. As of December 31, 2017, we had an accumulated deficit of approximately
$32,820,000. Our ability to achieve revenue-generating operations and, ultimately, achieve profitability will depend on whether
we can obtain additional capital when we need it, complete the development of our technology, receive regulatory approval of our
planned product candidates and find strategic collaborators that can incorporate our planned products candidates into new or existing
drugs which can be successfully commercialized. There can be no assurance that we will ever generate revenues or achieve profitability.





We currently do not have, and may never develop,
any FDA-approved or commercialized products.



We currently do not have any products approved by the FDA or
any other regulatory agency or any commercialized products and thus have never generated revenue from product sales. We have not
yet sought to obtain any regulatory approvals for any planned product candidates in the United States or in any foreign market.
Therefore, any estimated timing for our planned product candidates to be commercialized would be highly speculative.



To date, we have invested substantial resources in an exclusive
license with Albert Einstein College of Medicine (“Einstein”) that forms the foundation for our planned product candidates
and potential applications. For us to develop any products that might ultimately be commercialized, we will have to invest further
time and capital in research and product development, regulatory compliance and market development. Therefore, we and our licensor,
prospective business partners and other collaborators may never develop any products that can be commercialized. All of our development
efforts will require substantial additional funding, none of which may result in any revenue. Our efforts may not lead to commercially
successful products for a number of reasons, including:



| | · | we and our licensor, prospective business partners and other collaborators may not be able to complete research regarding,
and nonclinical and clinical development of, our planned product candidates;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | regulatory approvals and marketing authorizations may not be achieved for our planned product
candidates, or the scope of the approved indication may be narrower than sought;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | we and our licensor, prospective business partners and other collaborators may experience delays
in our development program, clinical trials and the regulatory approval process;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | our technology may not prove to be safe and effective in clinical or preclinical trials and our
planned product candidates may have adverse side effects which outweigh any potential benefit to patients;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | we may not be able to identify suitable collaborators to complete development or commercialization
of our potential products;
| | - | -----------------------------------------------------------------------------------------------------------------------------



25







| | · | we may not be able to maintain, protect or expand our portfolio of intellectual property rights,
including patents, trade secrets and know-how;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------



| | · | any future products that are ultimately approved by the FDA or other regulatory bodies may not
be commercially accepted in the marketplace by physicians or patients;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | our future products may not be able to be manufactured in commercial quantities or at an acceptable
cost;
| | - | ---------------------------------------------------------------------------------------------------------



| | · | physicians may not receive any reimbursement from third-party payors, or the level of reimbursement
may be insufficient to support widespread adoption of any of our future products; and
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | rapid technological change may make our technology and future products obsolete.
| | - | --------------------------------------------------------------------------------



Significant additional
research and development and clinical testing will be required before we can potentially seek regulatory approval for or commercialize
any of our product candidates.



We have product candidates in our oncology preclinical development
pipeline, but significant additional research and development activity and clinical testing are required before we and our collaborators
will have a chance to achieve a commercially viable product from such candidates. Our research and development efforts remain subject
to all of the risks associated with the development of new biopharmaceutical products and treatments based on immune modulation.
Development of the underlying technology may be affected by unanticipated technical or other problems, among other research and
development issues, and the possible insufficiency of funds needed in order to complete development of these product candidates.
Safety, regulatory and efficacy issues, clinical hurdles or other challenges may result in delays and cause us to incur additional
expenses that would increase our losses. If we and our collaborators cannot complete, or if we experience significant delays in
developing, our potential therapeutics or products for use in potential commercial applications, particularly after incurring significant
expenditures, our business may fail and investors may lose the entirety of their investment.



We have no history of conducting clinical trials
or commercializing biotechnology products, which may make it difficult to evaluate the prospects for our future viability.



Our operations to date have been limited to financing and staffing
our company, conducting research and developing our core technologies, and identifying and optimizing our lead product clinical
candidates. Although we have recruited a team that has experience with clinical trials in the United States, as a company, we have
no experience conducting clinical trials in any jurisdiction and have not had previous experience commercializing product candidates
or submitting an investigational new drug application (“IND”) or a Biologics License Application to the FDA or similar
submissions to initiate clinical trials or obtain marketing authorization to foreign regulatory authorities. We cannot be certain
that planned clinical trials will begin or be completed on time, if at all, that our planned development programs would be acceptable
to the FDA or other regulatory authorities, or that, if regulatory approval is obtained, our product candidates can be successfully
commercialized. Clinical trials and commercializing our product candidates will require significant additional financial and management
resources, and reliance on third-party clinical investigators, contract research organizations (“CROs”), consultants
and collaborators. Relying on third-party clinical investigators, CROs or collaborators may result in delays that are outside of
our control.



Furthermore, we may not have the financial resources to continue
development of, or to enter into collaborations for, a product candidate if we experience any problems or other unforeseen events
that delay or prevent regulatory approval of, or our ability to commercialize, product candidates, including:



| | · | negative or inconclusive results from our IND-enabling studies, clinical trials or the clinical trials of others for product
candidates similar to ours, leading to a decision or requirement to conduct additional preclinical testing or clinical trials or
abandon a program;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | delays in submitting INDs or comparable foreign applications or delays or failure in obtaining
the necessary approvals from regulators to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | conditions imposed by the FDA or a foreign regulatory authority regarding the number, scope or
design of our clinical trials;
| | - | -----------------------------------------------------------------------------------------------------------------------------



| | · | delays in enrolling patients in clinical trials;
| | - | ------------------------------------------------



26







| | · | high drop-out rates of patients;
| | - | --------------------------------



| | · | inadequate supply or quality of clinical trial materials or other supplies necessary to conduct
our clinical trials;
| | - | --------------------------------------------------------------------------------------------------------------------



| | · | greater than anticipated clinical trial costs;
| | - | ----------------------------------------------



| | · | poor effectiveness or unacceptable side effects of our product candidates during clinical trials;
| | - | -------------------------------------------------------------------------------------------------



| | · | unfavorable FDA or other regulatory agency inspection and review of a clinical trial site;
| | - | ------------------------------------------------------------------------------------------



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



| | · | serious and unexpected drug-related side effects or other safety issues experienced by participants
in our clinical trials or by individuals using drugs similar to our product candidates;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | delays and changes in regulatory requirements, policy and guidelines, including the imposition
of additional regulatory oversight around clinical testing generally or with respect to our technology in particular; or
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | varying interpretations of data by the FDA and foreign regulatory authorities.
| | - | ------------------------------------------------------------------------------



We have never dosed any of our product candidates
in humans. Our planned clinical trials or those of our collaborators may reveal significant adverse events, toxicities or other
side effects not seen in our preclinical studies and may result in a safety profile that could inhibit regulatory approval or market
acceptance of any of our product candidates.



In order to obtain marketing approval for any of our product
candidates, we must demonstrate the safety and efficacy of the product candidate for the relevant clinical indication or indications
through preclinical studies and clinical trials as well as additional supporting data. If our product candidates are associated
with undesirable side effects in preclinical studies or clinical trials or have characteristics that are unexpected, we may need
to interrupt, delay or abandon their development or limit development to more narrow uses or subpopulations in which the undesirable
side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective.



We have not yet initiated any clinical trials or dosed any of
our product candidates in humans. We have conducted various preclinical studies of our product candidates, but we do not know the
predictive value of these studies for humans, and we cannot guarantee that any positive results in preclinical studies will successfully
translate to human patients. It is not uncommon to observe results in human clinical trials that are unexpected based on preclinical
testing, and many product candidates fail in clinical trials despite promising preclinical results. Moreover, preclinical and clinical
data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates
performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval for their
products. Human patients in clinical trials may suffer significant adverse events or other side effects not observed in our preclinical
studies, including, but not limited to, immunogenic responses, organ toxicities such as liver, heart or kidney or other tolerability
issues or possibly even death. The observed potency and kinetics of our planned product candidates in preclinical studies may not
be observed in human clinical trials. If clinical trials of our planned product candidates fail to demonstrate efficacy to the
satisfaction of regulatory authorities or do not otherwise produce positive results, we may incur additional costs or experience
delays in completing, or ultimately be unable to complete, the development and commercialization of our planned product candidates.



If significant adverse events or other side effects are observed
in any of our future clinical trials, we may have difficulty recruiting patients to the clinical trial, patients may drop out of
our trial, or we may be required to abandon the trial or our development efforts of that product candidate altogether. We, the
FDA or other applicable regulatory authorities, or an Institutional Review Board (“IRB”) may suspend clinical trials
of a product candidate at any time for various reasons, including a belief that subjects in such trials are being exposed to unacceptable
health risks or adverse side effects. Some potential therapeutics developed in the biotechnology industry that initially showed
therapeutic promise in early-stage studies have later been found to cause side effects that prevented their further development.
Even if the side effects do not preclude the drug from obtaining or maintaining marketing approval, undesirable side effects may
inhibit market acceptance of the approved product due to its tolerability versus other therapies. Any of these developments could
materially harm our business, financial condition and prospects.



27







Further, if any of our product candidates obtains marketing
approval, toxicities associated with our product candidates may also develop after such approval and lead to a requirement to conduct
additional clinical safety trials, additional warnings being added to the labeling, significant restrictions on the use of the
product or the withdrawal of the product from the market. We cannot predict whether our product candidates will cause toxicities
in humans that would preclude or lead to the revocation of regulatory approval based on preclinical studies or early stage clinical
testing. However, any such event, were it to occur, would cause substantial harm to our business and financial condition and would
result in the diversion of our management’s attention.



We plan to seek collaborations or strategic alliances.
However, we may not be able to establish such relationships, and relationships we have established may not provide the expected
benefits.



On November 14, 2017, we entered into an Exclusive Patent License
and Research Collaboration Agreement (“Collaboration Agreement”) with Merck Sharpe & Dohme Corp. (“Merck”)
under which Merck will partner with us in the development of our CUE BiologicsTM targeting certain autoimmune diseases. Pursuant
to the collaboration agreement, Merck will acquire rights to develop, commercialize and sell CUE BiologicsTM relating to autoimmune
disease and, in exchange for such rights, has agreed to make payments to us that include a licensing fee, milestone payments and
sales royalties. This agreement does not commit Merck to a long-term relationship and it may disengage with us at any time upon
30 days’ notice.



Additionally, we plan to seek strategic alliances or collaborations
with other third parties that we believe will complement or augment our development and commercialization efforts with respect
to our planned product candidates and any future product candidates that we may develop. In addition, we currently do not have
sales, marketing, manufacturing or distribution capabilities or arrangements. In order to commercialize our potential products,
we plan to seek development and marketing partners or sublicensees to obtain necessary marketing, manufacturing and distribution
capabilities.



Any of these relationships may require us to incur non-recurring
and other charges, give up certain rights relating to our intellectual property and research and development activities, increase
our near and long-term expenditures, issue securities that dilute our existing stockholders, issue debt which may require liens
on our assets and which will increase our monthly expense obligations, or disrupt our management and business. Moreover, we may
not be successful in our efforts to establish additional strategic partnerships or other alternative arrangements for our planned
product candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties
may not view our planned product candidates as having the requisite potential to demonstrate safety and efficacy. If we are unable
to establish additional strategic partnerships or other alternative arrangements to develop our drug candidates, the costs for
us to independently develop our drug candidates may be higher than we currently anticipate, which could materially harm our business
prospects, financial condition and results of operation.



Further, collaborations involving our planned product candidates
are subject to numerous risks, which may include the following:



| | · | our collaborators may have significant discretion in determining the efforts and resources that they will apply to our collaboration
as compared to their other then-existing collaborations;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | our collaborators may not pursue development and commercialization of our product candidates or
may elect not to continue or renew development or commercialization of our programs based on clinical trial results, changes in
their strategic focus due to the acquisition of competitive products, availability of funding or other external factors, such as
a business combination that diverts resources or creates competing priorities;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | · | our collaborators could independently develop, or develop with third parties, products that compete
directly or indirectly with our product candidates;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------



28







| | · | a collaborator with marketing and distribution rights to one or more products may not commit sufficient
resources to the marketing and distribution of each of our potential products;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | our collaborators may not properly maintain or defend our intellectual property rights in accordance
with the terms of our contractual arrangements with them or may use our intellectual property or proprietary information in a way
that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary
information or expose us to other potential liability;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | disputes may arise between us and a collaborator that cause the delay or termination of the research,
development or commercialization of our product candidates, or that result in costly litigation or arbitration that diverts our
managements’ attention and our other resources;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | · | our collaborators may own or co-own intellectual property covering our potential products that
results from our collaboration with them, and in such case, we would not have the exclusive right to commercialize such intellectual
property without our collaborators’ involvement and consent.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



As a result, we may not be able to realize the benefit of collaboration
agreements, strategic partnerships or licenses of our technology or potential products, which could delay our product development
timelines or otherwise adversely affect our business. We also cannot be certain that, following a strategic transaction or license,
we will achieve sufficient revenue or net income to justify such transaction. Any delays in entering into new collaborations or
strategic partnership agreements related to our planned product candidates could delay the development and commercialization of
our planned product candidates in certain geographies for certain indications, which would harm our business prospects, financial
condition, and results of operations.



Our Collaboration Agreement with Merck contains
exclusivity and forbearance provisions that restrict our research and development activities.



We have granted to Merck under the Collaboration Agreement an
exclusive license under certain of our patent rights, including a sublicense of patent rights licensed from Einstein, to the extent
applicable to the specific CUE BiologicsTM that are elected to be developed by Merck. From the effective date of the Collaboration
Agreement until the earlier of (i) the first achievement of demonstration of certain biologically relevant effects for a Cue BiologicTM
drug candidate (“Proof of Mechanism”) or (ii) 18 months after we notify the joint steering committee that the first
product candidate has been synthesized under the research program, we are required to forebear from researching, developing or
licensing to a third party rights related to any CUE BiologicsTM drug candidate for the treatment of autoimmune diseases other
than pursuant to the Collaboration Agreement. In addition, so long as Merck continues product development on a CUE BiologicsTM
drug candidate that has demonstrated Proof of Mechanism (a “Proposed Product Candidate”), we are restricted from conducting
any development activities within the initial indication covered by such Proposed Product Candidate (each, an “Initial Indication”)
other than pursuant to the Collaboration Agreement. These restrictions on our development activities could impact our ability to
successfully develop drug candidates for the Initial Indications, which could harm our future business prospects for commercializing
drugs for those Initial Indications.



We may not be successful in our efforts to identify
additional product candidates. Due to our limited resources and access to capital, we must prioritize development of certain product
candidates; these decisions may prove to be wrong and may adversely affect our business.



Although we intend to explore other therapeutic opportunities,
in addition to the product candidates that we are currently developing, we may fail to identify successful product candidates for
clinical development for a number of reasons. If we fail to identify additional potential product candidates, our business could
be materially harmed.



Research programs to pursue the development of our planned product
candidates for additional indications and to identify new product candidates and disease targets require substantial technical,
financial and human resources whether or not they are ultimately successful. Our research programs may initially show promise in
identifying potential indications and/or product candidates, yet fail to yield results for clinical development for a number of
reasons, including:



29







| | · | the research methodology used may not be successful in identifying potential indications and/or product candidates;
| | - | -------------------------------------------------------------------------------------------------------------------



| | · | our key platform technologies, CUE BiologicsTM, MODTM, and viraTopeTM, may not
adequately enable us to design, discover and validate drug candidates;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------



| | · | potential product candidates may, after further study, be shown to have harmful adverse effects
or other characteristics that indicate they are unlikely to be effective drugs; or
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | it may take greater human and financial resources than we will possess to identify additional
therapeutic opportunities for our product candidates or to develop suitable potential product candidates through internal research
programs, thereby limiting our ability to develop, diversify and expand our drug portfolio.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Because we have limited financial and human resources, we intend
to initially focus on research programs and product candidates for a limited set of indications. As a result, we may forego or
delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial
potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial
products or profitable market opportunities.



Accordingly, there can be no assurance that we will ever be
able to identify additional therapeutic opportunities for our product candidates or to develop suitable potential product candidates
through internal research programs, which could materially adversely affect our future growth and prospects. We may focus our efforts
and resources on potential product candidates or other potential programs that ultimately prove to be unsuccessful.



We face significant competition from other biotechnology
and pharmaceutical companies, and our operating results will suffer if we fail to compete effectively.



The biopharmaceutical industry is characterized by intense competition
and rapid innovation. Our competitors may be able to develop other compounds or drugs that are able to achieve similar or better
results than our product candidates. Our competitors may include major multinational pharmaceutical companies, established biotechnology
companies, specialty pharmaceutical companies, and universities and other research institutions. Many of our competitors have substantially
greater financial, technical and other resources than we have, such as a larger research and development staff and experienced
marketing and manufacturing organizations, established relationships with CROs and other collaborators, as well as established
sales forces. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative
arrangements with large, established companies. Mergers and acquisitions in the biotechnology and pharmaceutical industries may
result in even more resources being concentrated in our competitors. Competition may increase further as a result of advances in
the commercial applicability of technologies and greater availability of capital for investment in these industries. Our competitors,
either alone or with collaborative partners, may succeed in developing, acquiring or licensing on an exclusive basis drug or biologic
products that are more effective, safer, more easily commercialized or less costly than our product candidates or may develop proprietary
technologies or secure patent protection and, in turn, exclude us from technologies that we may need for the development of our
technologies and potential products.



In the field of immunotherapeutics, we will face significant
competition from other companies, many of which have greater resources than we have. Immunotherapy technologies are advancing at
a rapid pace and we anticipate competing with the largest pharmaceutical companies in the world, such as F. Hoffman-La Roche AG
(Roche), Novartis A.G., Johnson & Johnson, Bristol-Myers Squibb and Merck & Co, as well as smaller biopharmaceutical companies
like Acceleron Pharma, Inc., Five Prime Therapeutics, Inc., Juno Therapeutics, Inc., Kite Pharma, Inc., Apitope International N.V.,
Seattle Genetics, Inc., Immatics Biotechnologies GmbH, Sutro Biopharma, Inc., ImmunoGen, Inc., Zyngenia, Inc., Immunocore Limited,
and Covagen A.G., which are all currently conducting research in immunotherapeutics and all of which have greater financial and
human resources than we currently have.



Even if we obtain regulatory approval of any of our product
candidates, we may not be the first to market and that may negatively affect the price or demand for our product candidates. Additionally,
we may not be able to implement our business plan if the acceptance of our product candidates is inhibited by price competition
or the reluctance of physicians to switch from existing methods of treatment to our product candidates, or if physicians switch
to other new drug or biologic products or choose to reserve our product candidates for use in limited circumstances. Furthermore,
a competitor could obtain orphan product exclusivity from the FDA with respect to such competitor’s product. If such competitor
product is determined to be the same product as one of our product candidates, we may be prevented from obtaining approval from
the FDA for such product candidate for the same indication for seven years, except in limited circumstances, and we may be subject
to similar restrictions under non-U.S. regulations.



30







If we lose key management personnel, or if we fail
to recruit additional highly skilled personnel, our ability to identify and develop new or next generation product candidates will
be impaired, could result in loss of markets or market share and could make us less competitive.



We are highly dependent upon the principal members of our management
team, including Daniel Passeri, M.Sc., our President and Chief Executive Officer, Ronald Seidel, Ph.D., our Executive VP of Research
and Development, Rodolfo Chaparro, Ph.D., our Executive VP of Immunology, and other members of our scientific and clinical advisory
team, including Steven Almo, Ph.D., the Chairman of our Scientific and Clinical Advisory Board. Our team has significant experience
and knowledge of oncology drug discovery and development, T cell modulation, protein biochemistry and immunological assays, and
the loss of any current or future team member could impair our ability to design, identify, and develop new intellectual property
and product candidates and new scientific or product ideas. Additionally, if we lose the services of any of these persons, we would
likely be forced to expend significant time and money in the pursuit of replacements, which may result in a delay in the development
of our product candidates and the implementation of our business plan and plan of operations and diversion of our management’s
attention. We can give no assurance that we could find satisfactory replacements for our current and future key scientific and
management employees on terms that would not be unduly expensive or burdensome to us.



To induce valuable personnel to remain at our Company, in addition
to salary and cash incentives, we have provided stock options that vest over time. Despite our efforts to retain valuable employees,
members of our management, scientific and development teams may terminate their employment with us on short notice. Although we
have employment agreements with our key employees, these employment agreements provide for at-will employment, which means that
these employees could leave our employment at any time, for or without cause. We do not maintain “key man” insurance
policies on the lives of these individuals or the lives of any of our other employees. Our success also depends on our ability
to continue to attract, retain and motivate highly skilled junior, mid-level and senior managers as well as junior, mid-level and
senior scientific and medical and scientific personnel.



Our internal computer systems, or those used by
third-party CROs, manufacturers or other contractors or consultants, may fail or suffer security breaches.



Despite the implementation of security measures, our internal
computer systems and those of our future CROs, manufacturers and other contractors and consultants are vulnerable to damage from
computer viruses and unauthorized access. Although to our knowledge we have not experienced any such material system failure or
security breach to date, if such an event were to occur, it could result in a material disruption of our development programs and
our business operations. For example, the loss of clinical trial data from future clinical trials could result in delays in our
regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption
or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential
or proprietary information (such as individually identifiable health information), we could incur significant liabilities and the
further development and commercialization of our product candidates could be delayed.



Risks Related to Intellectual Property and Other
Legal Matters



If we or our licensor are unable to protect our/its intellectual
property, then our financial condition, results of operations and the value of our technology and potential products could be adversely
affected.



Patents and other proprietary rights are essential to our business,
and our ability to compete effectively is dependent upon the proprietary nature of our technologies. We also rely upon trade secrets,
know-how, continuing technological innovations and licensing opportunities to develop, maintain and strengthen our competitive
position. We seek to protect these, in part, through confidentiality agreements with certain employees, consultants and other parties.
Our success will depend in part on the ability of ourselves and our licensor(s) to obtain, to maintain (including making periodic
filings and payments) and to enforce patent protection for its intellectual property, particularly those patent applications and
other intellectual property to which we have secured exclusive rights. We and our licensor(s) may not successfully prosecute or
continue to prosecute the patent applications which we have licensed. Even if patents are issued in respect of pending patent applications,
we or our licensor(s) may fail to maintain these patents, may determine not to pursue litigation against entities that are infringing
upon these patents, or may pursue such enforcement less aggressively than we ordinarily would. Without adequate protection for
the intellectual property that we own or license, others may be able to offer substantially identical products for sale, which
could unfavorably affect our competitive business position and harm our business prospects. Even if issued, patents may be challenged,
invalidated, or circumvented, which could limit our ability to stop competitors from marketing similar products or limit the length
of the term of patent protection that we may have for our potential products.



31







If we are unable to protect the confidentiality
of our proprietary information and know-how, the value of our technology and potential products could be adversely affected.



In addition to our licensed technology, we rely (and will continue
to rely) upon, among other things, unpatented proprietary technology, processes, trade secrets, trademarks, and know-how. Any involuntary
disclosure to or misappropriation by third parties of our confidential or proprietary information could enable competitors to duplicate
or surpass our technological achievements, potentially eroding our competitive position in our market. We seek to protect confidential
or proprietary information in part by confidentiality agreements with our employees, consultants and third parties. While we require
all of our employees, consultants, advisors and any third parties who have access to our proprietary know-how, information and
technology to enter into confidentiality agreements, we cannot be certain that this know-how, information and technology will not
be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent
information and techniques. These agreements may be terminated or breached, and we may not have adequate remedies for any such
termination or breach. Furthermore, these agreements may not provide meaningful protection for our trade secrets and know-how in
the event of unauthorized use or disclosure. To the extent that any of our staff was previously employed by other pharmaceutical,
medical technology or biotechnology companies, those employers may allege violations of trade secrets and other similar claims
in relation to their former employee’s therapeutic development activities for us. Any dispute involving such employees may
result in liabilities to us.



If we fail to comply with our obligations in the
agreements under which we license development or commercialization rights to products or technology from third parties, we could
lose license rights that are important to our business.



We hold an exclusive license from Einstein to intellectual property
relating to identification of novel immunomodulators, novel epitopes, and novel immunotherapy drugs. This license imposes various
developmental milestone obligations on us. If we fail to comply with any obligations under the license agreement and fail to cure
such noncompliance, Einstein will have the right to terminate the agreement and our license. The existing patent applications or
future patents to which we have rights based on our agreements with Einstein may be too specific and narrowly construed to prevent
third parties from developing or designing around the protection provided by these patents. Additionally, we may lose our rights
to the anticipated patents and patent applications we license in the event of termination of the license agreement. There is no
assurance that we will be successful in meeting all of the milestones in the future on a timely basis or that this important license
agreement will not be terminated for other reasons, depriving us of significant rights. The termination of this license agreement
would have a material adverse effect on our financial condition, results of operations, and prospects.



If we are unable to patent and protect the intellectual
property used in our potential products, others may be able to copy our innovations, which may impair our ability to compete effectively
in our markets.



The strength of our anticipated patents will involve complex
legal and scientific matters and can be uncertain. As of December 31, 2017, we own or have licensed 14 pending patent applications
in the United States (including 11 pending U.S. provisional patent applications), four pending international PCT applications
and 34 pending foreign patent applications intended to protect the intellectual property underlying our technology. Our patent
applications describe certain features of our technologies, including our CUE BiologicsTM platform and specific biologic
molecules and drug candidates, viraTopeTM, MODTM screening, MODTM variants and MODTM combinations. Our anticipated
patents may be challenged or fail to result in issued patents and anticipated patents may be too specific and narrowly construed
to prevent third parties from developing or designing around the protections provided by our intellectual property and in that
event we may lose competitive advantage and our business may suffer. Further, the patent applications that we license or have
filed may fail to result in issued patents or the claims may need to be amended. Even after amendment, a patent may not issue.
In that event, we may not obtain the exclusive use of the intellectual property that we seek and we may lose competitive advantage,
which could result in harm to our business.



32







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



Filing, prosecuting, maintaining and defending patents on product
candidates in all countries throughout the world could be prohibitively expensive for us, and our intellectual property rights
in some non-U.S. countries can have a different scope and strength than do those in the United States. In addition, the laws of
certain non-U.S. countries do not protect intellectual property rights to the same extent as U.S. federal and state laws do. Consequently,
we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from
selling or importing drugs made using our inventions in and into the United States or non-U.S. jurisdictions. Competitors may use
our technologies in jurisdictions where we have not obtained patent protection to develop their own drugs and further, may export
otherwise infringing drugs to non-U.S. jurisdictions where we have patent protection, but where enforcement rights are not as strong
as those in the United States. These drugs may compete with our product candidates and our patent rights or other intellectual
property rights may not be effective or adequate to prevent them from competing.



Many U.S.-based companies have encountered significant problems
in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of some countries do not favor
the enforcement of patents, trade secrets and other intellectual property, particularly those relating to biopharmaceutical products,
which could make it difficult in those jurisdictions for us to stop the infringement or misappropriation of our anticipated patents
or other intellectual property rights, or the marketing of competing drugs in violation of our proprietary rights. Proceedings
to enforce our patent and other intellectual property rights in non-U.S. jurisdictions could result in substantial costs and divert
our efforts and attention from other aspects of our business.



Furthermore, such proceedings could put our anticipated patents
at risk of being invalidated, held unenforceable or interpreted narrowly, could put our patent applications at risk of not issuing,
and could provoke third parties to assert claims of infringement or misappropriation against us. We may not prevail in any lawsuits
that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts
to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from
the intellectual property that we develop.



Litigation or third-party claims of intellectual
property infringement or challenges to the validity of our anticipated patents would require us to use resources to protect our
technology and may prevent or delay our development, regulatory approval or commercialization of our product candidates.



If we are the target of claims by third parties asserting that
our potential products or intellectual property infringe upon the rights of others we may be forced to incur substantial expenses
or divert substantial employee resources from our business. If successful, those claims could result in our having to pay substantial
damages or could prevent us from developing one or more product candidates. Further, if a patent infringement suit is brought against
us or our collaborators, we or they could be forced to stop or delay research, development, manufacturing or sales of the product
or product candidate that is the subject of the suit.



If we or our collaborators experience patent infringement claims,
or if we elect to avoid potential claims others may be able to assert, we or our collaborators may choose to seek, or be required
to seek, a license from the third party and would most likely be required to pay license fees or royalties or both. These licenses
may not be available on acceptable terms, or at all. Even if we or our collaborators were able to obtain a license, the rights
may be nonexclusive, which would give our competitors access to the same intellectual property. Ultimately, we could be prevented
from commercializing a product, or be forced to cease some aspect of our business operations if, as a result of actual or threatened
patent infringement claims, we or our collaborators are unable to enter into license agreements on acceptable terms. This could
harm our business significantly. The cost to us of any litigation or other proceeding, regardless of its merit, and even if resolved
in our favor, could be substantial. Some of our competitors may be able to bear the costs of such litigation or proceedings more
effectively than we can because of their having greater financial and human 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. Intellectual property litigation and other proceedings may, regardless of their merit, also absorb significant management
time and employee resources.



33







Although we are not currently aware of any litigation or other
proceedings or third-party claims of intellectual property infringement, the therapeutic industry is characterized by many suits
regarding patents and other intellectual property rights. Other parties may in the future allege that our activities infringe upon
their patents or that we are employing their proprietary technology without authorization. We may not have identified all the patents,
patent applications or published literature that affect our business either by blocking our ability to commercialize our potential
products, by preventing the patentability of one or more aspects of our potential products or those of our licensor or by covering
the same or similar technologies that may affect our ability to market our potential products. In addition, even in the absence
of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our product
candidates, and we have done so from time to time. We may fail to obtain future licenses at a reasonable cost or on reasonable
terms, if at all. In that event, we may be unable to further develop and commercialize one or more of our product candidates, which
could harm our business significantly.



If product liability lawsuits are brought against
us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.



We will face an inherent risk of product liability as a result
of the clinical testing of our product candidates and will face an even greater risk if we commercialize any drugs. For example,
we may be sued if our product candidates cause or are perceived to cause injury or death or are found to be otherwise unsuitable
during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects
in manufacturing, defects in design, a failure to warn of dangers inherent in the drug, negligence, strict liability or a breach
of warranties. Claims could also be asserted under state or foreign consumer protection laws. If we cannot successfully defend
ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our
product candidates. Even a successful defense would require significant financial and management resources. Regardless of the merits
or eventual outcome, liability claims may result in:



| | · | decreased demand for our potential drugs;
| | - | -----------------------------------------



| | · | injury to our reputation and significant negative media attention;
| | - | ------------------------------------------------------------------



| | · | withdrawal of clinical trial participants and inability to continue clinical trials;
| | - | ------------------------------------------------------------------------------------



| | · | initiation of investigations by regulators;
| | - | -------------------------------------------



| | · | costs to defend the related litigation;
| | - | ---------------------------------------



| | · | a diversion of management’s time and our resources;
| | - | ---------------------------------------------------



| | · | substantial monetary awards to trial participants or patients;
| | - | --------------------------------------------------------------



| | · | product recalls, withdrawals or labeling, marketing or promotional restrictions;
| | - | --------------------------------------------------------------------------------



| | · | loss of revenue;
| | - | ----------------



| | · | financial cost;
| | - | ---------------



| | · | exhaustion of any available insurance and our capital resources; and
| | - | --------------------------------------------------------------------



| | · | the inability to commercialize any product candidate.
| | - | -----------------------------------------------------



Our inability to obtain sufficient product liability insurance
at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of drugs
we develop, alone or with collaborators. Our insurance policies may also have various exclusions, and we may be subject to a product
liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement
that exceed our insurance coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain,
sufficient capital to pay such amounts. Even if our agreements with any future collaborators entitle us to indemnification against
losses, such indemnification may not be available or adequate should any claim arise.



34







We may be subject to securities litigation, which
is expensive and could divert management attention.



The price of our common stock may be volatile, and in the past
companies that have experienced volatility in the market price of their common stock have been subject to an increased incidence
of securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against
us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously
harm our business.



Risks Related to Government Regulation



We are subject to regulation in respect of our research
and federal funding.



Because our licensor has conducted research under federal grants
and we may conduct further research under federal grants, we will be subject to federal regulation in how we conduct our research
and the agreement terms relating to those grants. There are also ethical guidelines promulgated by various governments and research
institutions that we are required to follow in respect of our research. These guidelines are orientated towards research and experimentation
involving humans and animals. Failure to follow the regulations, agreement terms and accepted scientific practices would jeopardize
our grants and our results and the use of the results in further research and approval circumstances. Because our licensor has
used federal funding, the government retains a “march-in” right in connection with these grants, which is the right
to grant additional licenses to practice inventions developed from grant funding. The exercise of these “march-in”
rights could result in decreased demand for our future products, which could have a material adverse effect on our results of operations
and financial condition. In addition, any failure to comply with applicable laws or regulations could harm our business and divert
our management’s attention.



We will be subject to stringent domestic and foreign
therapeutic and drug regulation in respect of any potential products. The regulatory approval processes of the FDA and other comparable
regulatory authorities outside the United States are lengthy, time-consuming and inherently unpredictable. Any unfavorable regulatory
action may materially and adversely affect our future financial condition and business operations.



Our potential products, further development activities and manufacturing
and distribution, once developed and determined, will be subject to extensive and rigorous regulation by numerous government agencies,
including the FDA and comparable foreign agencies. To varying degrees, each of these agencies monitors and enforces our compliance
with laws and regulations governing the development, testing, manufacturing, labeling, marketing, distribution, and the safety
and effectiveness of our drugs. The process of obtaining marketing approval or clearance from the FDA and comparable foreign bodies
for new products, or for enhancements, expansion of the indications or modifications to existing products, could:



| | · | take a significant, indeterminate amount of time;
| | - | -------------------------------------------------



| | · | require the expenditure of substantial resources;
| | - | -------------------------------------------------



| | · | involve rigorous preclinical and clinical testing, and possibly post-market surveillance;
| | - | -----------------------------------------------------------------------------------------



| | · | involve modifications, repairs or replacements of our potential products;
| | - | -------------------------------------------------------------------------



| | · | require design changes of our potential products;
| | - | -------------------------------------------------



| | · | result in limitations on the indicated uses of our potential products; or
| | - | -------------------------------------------------------------------------



| | · | result in our never being granted the regulatory approval we seek.
| | - | ------------------------------------------------------------------



35







Any of these occurrences may cause our operations or potential
for success to suffer, harm our competitive standing and result in further losses that adversely affect our financial condition.
We will have ongoing responsibilities under FDA and international regulations, both before and after a product is approved and
commercially released. Compliance with applicable regulatory requirements is subject to continual review and is monitored rigorously
through periodic inspections by the FDA. If the FDA were to conclude that there is non-compliance with applicable laws or regulations,
or that any of our potential therapeutics are ineffective or pose an unreasonable health risk, the FDA could ban such drugs, detain
or seize such drugs, order a recall, repair, replacement, or refund of purchases of such drugs, or require us to notify health
professionals and others that the drugs present unreasonable risks of substantial harm to the public health. Additionally, the
FDA may impose other operating restrictions, enjoin and restrain certain violations of applicable law pertaining to therapeutics
and assess civil or criminal penalties against us, our officers, our employees, or our collaborative partners. The FDA has increased
its scrutiny of the therapeutic industry and U.S. and foreign governments are expected to continue to scrutinize the industry closely
with inspections and possibly enforcement actions by the FDA or other agencies. Any adverse regulatory action, depending on its
magnitude, may restrict us from effectively commercializing our potential products. In addition, negative publicity and product
liability claims resulting from any adverse regulatory action could have a material adverse effect on our financial condition and
results of operations.



We may seek orphan drug status or breakthrough therapy
designation for one or more of our product candidates, but even if either is granted, we may be unable to maintain any benefits
associated with orphan drug status or breakthrough therapy designation, including market exclusivity.



Under the Orphan Drug Act, the FDA may grant orphan designation
to a drug or biologic intended to treat a rare disease or condition or for which there is no reasonable expectation that the cost
of developing and making available in the United States a drug or biologic for a disease or condition will be recovered from sales
in the United States for that drug or biologic. If a product that has orphan drug designation subsequently receives the first FDA
approval for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means
that the FDA may not approve any other applications, including a full Biologics License Application, to market the same drug or
biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to
the product with orphan drug exclusivity. In 2012, the FDA established a Breakthrough Therapy Designation which is intended to
expedite the development and review of products that treat serious or life-threatening conditions.



We may seek orphan drug status for one or more of our products
candidates, but the FDA may not approve any such request. Even if the FDA grants orphan drug status to one or more of our product
candidates, exclusive marketing rights in the United States may be limited if we seek FDA marketing approval for an indication
broader than the orphan designated indication. Additionally, any product candidate that initially receives orphan drug status designation,
may lose such designation 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. In addition,
we may seek breakthrough therapy designation for one or more of our product candidates, but there can be no assurance that we will
receive such designation. In addition, others may obtain orphan drug status for products addressing the same diseases or conditions
as products we are developing, thus limiting our ability to compete in the markets addressing such diseases or conditions for a
significant period of time.



We may seek fast-track designation for our drug
product candidates. Even if received, fast-track designation may not actually lead to a faster review process.



We aim to benefit from the FDA’s fast track and accelerated
approval processes. However, our drug product candidates may not receive an FDA fast-track designation or priority review. Without
fast-track designation, submitting a new drug application, or NDA, and getting through the regulatory process to gain marketing
approval is a lengthy process. Under fast-track designation, the FDA may initiate review of sections of a fast-track drug’s
NDA before the application is complete. However, the FDA’s time period goal for reviewing an application does not begin until
the last section of the NDA is submitted. Additionally, the fast-track designation may be withdrawn by the FDA if the FDA believes
that the designation is no longer supported by data emerging in the clinical trial process. Under the FDA policies, a drug candidate
is eligible for priority review, or review within a six-month time frame from the time a complete NDA is accepted for filing, if
the drug candidate provides a significant improvement compared to marketed drugs in the treatment, diagnosis or prevention of a
disease. A fast-track designated drug candidate would ordinarily meet the FDA’s criteria for priority review.



The fast-track designation for our drug product candidates,
if obtained, may not actually lead to a faster review process and a delay in the review process or in the approval of our potential
products will delay revenue from their potential sales and will increase the capital necessary to fund these product development
programs.



36







To obtain the necessary approval of our potential
products, as a precondition, there will have to be conducted various preclinical and clinical tests, all of which will be costly
and time consuming, and may not provide results that will allow us to seek regulatory approval.



The number of preclinical and clinical tests that will be required
for regulatory approval varies depending on the disease or condition to be treated, the method of treatment, the nature of the
drug, the jurisdiction in which approval is sought and the applicable regulations. Regulatory agencies can delay, limit or deny
approval of a product for many reasons. For example, regulatory agencies may:



| | · | not deem a therapeutic to be safe or effective;
| | - | -----------------------------------------------



| | · | interpret data from preclinical and clinical testing differently than we do;
| | - | ----------------------------------------------------------------------------



| | · | not approve the manufacturing processes;
| | - | ----------------------------------------



| | · | conclude that our drug candidate does not meet quality standards for durability, long-term reliability, biocompatibility, compatibility,
or safety; and
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | change their approval policies or adopt new regulations.
| | - | --------------------------------------------------------



The FDA may make requests or suggestions regarding conduct of
any clinical trials, resulting in an increased risk of difficulties or delays in obtaining regulatory approval in the United States.
Foreign regulatory agencies may similarly have the ability to influence any clinical trials occurring outside the United States.
Any of these occurrences could prove materially harmful to our operations and business.



Even if a potential therapeutic is ultimately approved
by the various regulatory authorities, it may be approved only for narrow indications which may render it commercially less viable.



Even if a potential therapeutic of ours is approved, it may
not be approved for the indications that are necessary or desirable for successful commercialization. Our preference will be to
obtain as broad an indication as possible for use in connection with the particular disease and treatment for which it is designed.
However, the final classification may be more limited than originally sought. The limitation on use may make the product commercially
less viable and more difficult, if not impractical, to market.



Therefore, we may not obtain the revenues that we seek in respect
of the proposed product, and we may not be able to become profitable and provide an investment return to our investors.



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



Any regulatory approvals that we receive for our product candidates
will require surveillance to monitor the safety and efficacy of the product candidate. The FDA or foreign regulatory agencies may
also require a risk evaluation and mitigation strategy in order to approve our product candidates, which could entail requirements
for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution
methods, patient registries and other risk minimization tools. In addition, if the FDA or a comparable foreign regulatory authority
approves our product 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 continued compliance with current good manufacturing processes (“cGMPs”) and current good clinical practices
(“cGCPs”) for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with
our product candidates, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers
or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:



| | · | restrictions on the marketing or manufacturing of our product candidates, withdrawal of the product from the market, or voluntary
or mandatory product recalls;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



37







| | · | fines, warning letters or holds on clinical trials;
| | - | ---------------------------------------------------



| | · | refusal by the FDA to approve pending applications or supplements to approved applications filed by us or suspension or revocation
of license approvals;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | product seizure or detention, or refusal to permit the import or export of our product candidates; and
| | - | ------------------------------------------------------------------------------------------------------



| | · | injunctions or the imposition of civil or criminal penalties.
| | - | -------------------------------------------------------------



The FDA’s and other regulatory authorities’ policies
may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product
candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation
or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements
or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any approval
that we may have obtained and we may not achieve or sustain profitability.



Unfavorable pricing regulations, third-party reimbursement
practices or healthcare reform initiatives could harm our business in the future.



There is increasing pressure on biotechnology companies to reduce
healthcare costs. In the United States, these pressures come from a variety of sources, such as managed care groups and institutional
and government purchasers. Increased purchasing power of entities that negotiate on behalf of federal healthcare programs and private
sector beneficiaries could increase pricing pressures in the future. Such pressures may also increase the risk of litigation or
investigation by the government regarding pricing calculations. The biotechnology industry will likely face greater regulation
and political and legal actions in the future.



Adverse pricing limitations may hinder our ability to recoup
our investment in one or more future product candidates, even if our future product candidates obtain regulatory approval. Adverse
pricing limitations prior to approval will also adversely affect us by reducing our commercial potential. Our ability to commercialize
any potential products successfully also will depend in part on the extent to which reimbursement for these products and related
treatments becomes available from government health administration authorities, private health insurers and other organizations.
Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which
medications they will pay for and establish reimbursement levels.



A significant trend in the U.S. healthcare industry and elsewhere
is cost containment. Government authorities and these third-party payors have attempted to control costs by limiting coverage and
the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that companies provide them
with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that
coverage and reimbursement will be available for any product that we commercialize in the future and, if reimbursement is available,
what the level of reimbursement will be. Reimbursement may impact the demand for, or the price of, any product for which we obtain
marketing approval in the future. If reimbursement is not available or is available only to limited levels, we may not be able
to successfully commercialize any product candidate that we successfully develop.



There may be significant delays in obtaining reimbursement for
approved products, and coverage may be more limited than the purposes for which the product is approved by the FDA or regulatory
authorities in other countries. Moreover, eligibility for reimbursement does not imply that any product will be paid for in all
cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim payments
for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Payment rates may
vary according to the use of the product and the clinical setting in which it is used, may be based on payments allowed for lower
cost products that are already reimbursed and may be incorporated into existing payments for other services. Net prices for products
may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future
relaxation of laws that presently restrict imports of products from countries where they may be sold at lower prices than in the
United States. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement
policies. Our inability to promptly obtain coverage and profitable payment rates from both government funded and private payors
for future products that we develop could have a material adverse effect on our operating results, our ability to raise capital
needed to commercialize potential products and our overall financial condition.



38







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



Our business operations will subject us to numerous environmental,
health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment
and disposal of hazardous materials and wastes. Our operations may involve the use of hazardous and flammable materials, including
chemicals and biological materials. Our operations also may produce hazardous waste products. We expect to generally contract with
third parties for the disposal of these materials and wastes. However, we cannot eliminate the risk of contamination or injury
from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable
for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with
civil or criminal fines and penalties. In addition, we may be required to incur substantial costs to comply with current or future
environmental, health and safety laws and regulations.



These current or future laws and regulations may impair our
research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines,
penalties or other sanctions and we may not have sufficient (or any) insurance to cover any such costs.



Risks Related to Owning Our Common Stock, Our Financial
Results and Our Need for Financing



We anticipate future losses and negative cash flow,
and it is uncertain if or when we will become profitable.



We do not expect to generate any revenues until we successfully
complete development of our first potential products and we are able to successfully commercialize them through sales and licensing.
We have not yet demonstrated our ability to generate revenue, and we may never be able to produce revenues or operate on a profitable
basis. As a result, we have incurred losses since our inception and expect to experience operating losses and negative cash flow
for the foreseeable future. Our planned product candidates may never be approved or become commercially viable. Even if we and
our collaborators are able to commercialize our technology, which may include licensing, we may never recover our research and
development expenses.



We expect to require additional financing to support our growth
and ongoing operations. Additional capital may be difficult to obtain, restrict our operations, require us to relinquish rights
to our technologies or product candidates, encumber our assets and result in ongoing debt service cost, or result in additional
dilution to our stockholders.



Our business will require additional capital for implementation
of our long term business plan and product development and commercialization. As we require additional funds, we may seek to fund
our operations through the sale of additional equity securities, debt financing and/or strategic collaboration agreements. We cannot
be sure that additional financing from any of these sources will be available when needed or that, if available, the additional
financing will be obtained on favorable terms.



Our future funding requirements will depend on many factors,
including, but not limited to:



| | · | the progress, timing, scope and costs of our clinical trials, including the ability to timely enroll patients in our planned
and potential future clinical trials;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | the outcome, timing and cost of regulatory approvals by the FDA and comparable regulatory authorities, including the potential
that the FDA or comparable regulatory authorities may require that we perform more studies than those that we currently expect;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | the number and characteristics of product candidates that we may in-license and develop;
| | - | ----------------------------------------------------------------------------------------



| | · | our ability to successfully commercialize our product candidates;
| | - | -----------------------------------------------------------------



| | · | the amount of sales and other revenues from product candidates that we may commercialize, if any, including the selling prices
for such potential products and the availability of adequate third-party reimbursement;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



39







| | · | selling and marketing costs associated with our potential products, including the cost and timing of expanding our marketing
and sales capabilities;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------



| | · | the terms and timing of any potential future collaborations, licensing or other arrangements that we may establish;
| | - | -------------------------------------------------------------------------------------------------------------------



| | · | cash requirements of any future acquisitions and/or the development of other product candidates;
| | - | ------------------------------------------------------------------------------------------------



| | · | the costs of operating as a public company;
| | - | -------------------------------------------



| | · | the cost and timing of completion of commercial-scale, outsourced manufacturing activities;
| | - | -------------------------------------------------------------------------------------------



| | · | the time and cost necessary to respond to technological and market developments;
| | - | --------------------------------------------------------------------------------



| | · | any disputes which may occur between us and Einstein, employees, collaborators or other prospective business partners; and
| | - | --------------------------------------------------------------------------------------------------------------------------



| | · | the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights.
| | - | -------------------------------------------------------------------------------------------------------------------



If we raise additional funds by selling shares of our common
stock or other equity-linked securities, the ownership interest of our current stockholders will be diluted. We may seek to access
the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional
capital at that time. 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 technologies, future revenue streams or product
candidates or to grant licenses on terms that may not be acceptable to us. If we raise additional funds through debt financing,
we may have to grant a security interest on our assets to the future lenders, our debt service costs may be substantial, and the
lenders may have a preferential position in connection with any future bankruptcy or liquidation involving the company.



If we are unable to raise additional capital when needed, we
may be required to curtail the development of our technology or materially curtail or reduce our operations. We could be forced
to sell or dispose of our rights or assets. Any inability to raise adequate funds on commercially reasonable terms could have a
material adverse effect on our business, results of operation and financial condition, including the possibility that a lack of
funds could cause our business to fail and the Company to dissolve and liquidate with little or no return to investors.



We are an “emerging growth company”
under the JOBS Act and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will
make our common stock less attractive to investors.



We are an “emerging growth company,” as defined
in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and we may take advantage of certain exemptions
from various reporting requirements that are applicable to other public companies that are not “emerging growth companies”
including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley
Act of 2002 (the “Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in our periodic
reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation
and stockholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our
common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as
a result, there may be a less active trading market for our common stock and our stock price may be more volatile.



We will remain an “emerging growth company” for
up to five years following the initial public offering of our common stock, although we will lose that status sooner if our revenues
exceed $1 billion, if we issue more than $1 billion in non-convertible debt in a three year period, or if the market value of our
common stock that is held by non-affiliates exceeds $700 million as of any June 30.



Our status as an “emerging growth company”
under the JOBS Act may make it more difficult to raise capital as and when we need it.



Because of the exemptions from various reporting requirements
provided to us as an “emerging growth company,” we may be less attractive to investors and it may be difficult for
us to raise additional capital as and when we need it. Investors may be unable to compare our business with other companies in
our industry if they believe that our reporting is not as transparent as other companies in our industry. If we are unable to raise
additional capital as and when we need it, our financial condition and results of operations may be materially and adversely affected.



40







Our stock price can be volatile and investors may
have difficulty selling their shares.



Our common stock is currently listed on the Nasdaq under the
symbol “CUE.” The price of our common stock may fluctuate significantly in response to market and other factors, some
of which are beyond our control, including those listed in this “Item 1A. Risk Factors” section and other, unknown
factors. Our stock price may also be affected by:



| | · | setbacks with respect to our research and development programs;
| | - | ---------------------------------------------------------------



| | · | announcements of therapeutic innovations or new products by us or our competitors;
| | - | ----------------------------------------------------------------------------------



| | · | adverse actions taken by regulatory agencies with respect to our clinical trials;
| | - | ---------------------------------------------------------------------------------



| | · | any adverse changes to our relationship with collaborators;
| | - | -----------------------------------------------------------



| | · | results of internal and external studies and clinical trials;
| | - | -------------------------------------------------------------



| | · | result of our business development efforts;
| | - | -------------------------------------------



| | · | variations in the level of expenses related to our existing product candidates or preclinical and clinical development programs;
| | - | --------------------------------------------------------------------------------------------------------------------------------



| | · | any intellectual property infringement actions in which we may become involved;
| | - | -------------------------------------------------------------------------------



| | · | variations in our results of operations;
| | - | ----------------------------------------



| | · | press reports, whether or not true, about our business;
| | - | -------------------------------------------------------



| | · | additions to or departures of our management;
| | - | ---------------------------------------------



| | · | release or expiry of lock-up or other transfer restrictions on our outstanding ordinary shares or our common stock;
| | - | -------------------------------------------------------------------------------------------------------------------



| | · | sales or perceived potential sales of additional ordinary shares or our common stock;
| | - | -------------------------------------------------------------------------------------



| | · | sales of our common stock by us, our executive officers and directors or our stockholders in the future; and
| | - | ------------------------------------------------------------------------------------------------------------



| | · | general economic and market conditions and overall fluctuations in the U.S. equity markets.
| | - | -------------------------------------------------------------------------------------------



Any of these factors may result in large and sudden changes
in the volume and trading price of our common stock. In addition, the stock market, in general, and small pharmaceutical and biotechnology
companies have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating
performance of these companies. Broad market and industry factors beyond our control may negatively affect the market price of
our common stock, regardless of our actual operating performance, and cause the price of our common stock to decline rapidly and
unexpectedly.



If securities or industry analysts do not publish
research reports about our business, or if they issue an adverse opinion about our business, the price of our securities and trading
volume could decline.



The trading market for our securities is influenced by the research
and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain
research coverage by securities and industry analysts. If no or few analysts commence research coverage of us, or one or more of
the analysts who cover us issues an adverse opinion about our company, the price of our securities would likely decline. If one
or more of these analysts ceases research coverage of us or fails to regularly publish reports on us, we could lose visibility
in the financial markets, which in turn could cause the price of our securities or trading volume to decline.



41







We have not paid dividends in the past and have
no immediate plans to pay dividends.



We plan to reinvest all of our earnings, to the extent we have
earnings, in order to further develop our technology and potential products and to cover operating costs. We do not plan to pay
any cash dividends with respect to our securities in the foreseeable future. We cannot assure you that we would, at any time, generate
sufficient surplus cash that would be available for distribution to the holders of our common stock as a dividend.



Concentration of ownership among our executive officers,
directors and significant stockholders may prevent new investors from influencing significant corporate decisions.



All decisions with respect to the management of the company
will be made by our board of directors and our officers, who beneficially own approximately 16.6% of our common stock at December
31, 2017, as calculated in accordance with Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange
Act”). Such percentage includes the approximately 10.2% of our common stock beneficially owned by MDB Capital Group, LLC
(“MDB”), which served as the underwriter in our initial public offering and placement agent in previous private placements
of our common stock, and of which three of our seven directors are employees. As a result, management and MDB will be able to exercise
a significant level of control over all matters requiring stockholder approval, including the election of directors, amendment
of our certificate of incorporation and approval of significant corporate transactions. This control could have the effect of delaying
or preventing a change of control of the company or changes in management, in each case, which other stockholders might find favorable,
and will make the approval of certain transactions difficult without the support of these significant stockholders.



A significant portion of our total outstanding shares
of common stock is restricted from immediate resale but may be sold into the market in the near future. This could cause the market
price of our securities to drop significantly, even if our business is doing well.





Sales of a substantial number of shares of our common stock
in the public market could occur in the future. These sales, or the perception in the market that the holders of a large number
of securities intend to sell shares, could reduce the market price of our common stock. We currently have outstanding 19,459,194
shares of common stock. Of these outstanding shares, approximately 10,638,484 are restricted under securities laws or as a
result of lock-up agreements but will be able to be resold in the near future. We also intend to register all shares of common
stock that we may issue under our equity compensation plans. Once we register these shares, they can be freely sold in the public
market upon issuance and once vested, subject to 180- and 365-day lock-up periods under certain lock-up agreements.



We expect to continue to incur significant costs
as a result of being a public company that reports to the Securities and Exchange Commission and our management will be required
to devote substantial time to meet compliance obligations.



As a public company reporting to the Securities and Exchange
Commission (“SEC”), we incur significant legal, accounting and other expenses. We are subject to reporting requirements
of the Exchange Act and the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), as well as rules subsequently implemented
by the SEC that impose significant requirements on public companies, including requiring establishment and maintenance of effective
disclosure and financial controls and changes in corporate governance practices. In addition, there are significant corporate governance
and executive compensation-related provisions in the Dodd-Frank Wall Street Reform and Protection Act that increase public companies’
legal and financial compliance costs, make some activities more difficult, time-consuming or costly and may also place undue strain
on personnel, systems and resources. Our management and other personnel are expected to devote a substantial amount of time to
these compliance initiatives. In addition, we expect these rules and regulations to make it more difficult and more expensive for
us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur
substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and
retain qualified people to serve on our board of directors, our board committees or as executive officers.



42







Our charter documents and Delaware law may inhibit
a takeover that stockholders consider favorable.



Provisions of our amended and restated certificate of incorporation
(the “Certificate of Incorporation”) and our amended and restated bylaws (the “Bylaws”) and applicable
provisions of Delaware law may delay or discourage transactions involving an actual or potential change in control or change in
our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions
that our stockholders might otherwise deem to be in their best interests. The provisions in our Certificate of Incorporation and
Bylaws:



| | · | authorize our board of directors to issue preferred stock without stockholder approval and to designate the rights, preferences
and privileges of each class; if issued, such preferred stock would increase the number of outstanding shares of our common stock
and could include terms that may deter an acquisition of us;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | limit who may call stockholder meetings;
| | - | ----------------------------------------



| | · | do not provide for cumulative voting rights;
| | - | --------------------------------------------



| | · | provide that all vacancies may be filled only by the affirmative vote of a majority of directors then in office, even if less
than a quorum;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------



| | · | provide that stockholders must comply with advance notice procedures with respect to stockholder proposals and the nomination
of candidates for director;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | provide that stockholders may only amend our Certificate of Incorporation and Bylaws upon a supermajority vote of stockholders;
and
| | - | -----------------------------------------------------------------------------------------------------------------------------------



| | · | provide that the Court of Chancery of the State of Delaware will be the exclusive forum for certain legal claims.
| | - | -----------------------------------------------------------------------------------------------------------------



In addition, Section 203 of the Delaware General Corporation
Law may limit our ability to engage in any business combination with a person who beneficially owns 15% or more of our outstanding
voting stock unless certain conditions are satisfied. This restriction lasts for a period of three years following the share acquisition.
These provisions may have the effect of entrenching our management team and may deprive you of the opportunity to sell your shares
to potential acquirers at a premium over prevailing prices. This potential inability to obtain a control premium could reduce the
price of our common stock.



Our Certificate of Incorporation provides, subject
to certain exceptions, that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for certain stockholder
litigation matters, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us
or our directors, officers, employees or stockholders.



Our Certificate of Incorporation provides, subject to limited
exceptions, that the Court of Chancery of the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive
forum for (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a claim of breach of a fiduciary
duty owed by any of our directors, officers or other employees to us or our stockholders; (3) any action asserting a claim against
us, any director or our officers and employees arising pursuant to any provision of the Delaware General Corporation Law, our Certificate
of Incorporation or our Bylaws, or as to which the Delaware General Corporation Law confers exclusive jurisdiction on the Court
of Chancery; or (4) any action asserting a claim against us, any director or our officers or employees that is governed by the
internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of our common stock shall
be deemed to have notice of and to have consented to the provisions of our Certificate of Incorporation described above. This choice
of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes
with us or any of our directors, officers, other employees or stockholders which may discourage lawsuits with respect to such claims.
Alternatively, if a court were to find the choice of forum provision that will be contained in our Certificate of Incorporation
to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other
jurisdictions, which could materially adversely affect our business, financial condition and results of operations.



43







If we are unable to implement and maintain effective
internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports
and the market price of our securities may decrease.



Beginning with our annual report for the year ending December 31,
2018, Section 404 of the Sarbanes-Oxley Act will require that we evaluate and determine the effectiveness of our internal
control over financial reporting and provide a management report on our internal control over financial reporting which following
our no longer being an “emerging growth company,” must be attested to by our independent registered public accounting
firm.



If we are unable to comply with the requirements of Section
404 in a timely manner, if we are unable to assert that our internal control over financial reporting is effective or, once required,
provide an attestation report from our independent registered public accounting firm, investors may lose confidence in the accuracy
and completeness of our financial reports and the market price of our common stock could decrease. We could also become subject
to stockholder or other third-party litigation as well as investigations by the stock exchange on which our securities are listed,
the SEC or other regulatory authorities, which could require additional financial and management resources and could result in
fines, trading suspensions or other remedies.

Item 1B. Unresolved Staff Comments



Not applicable.



Item
2. Properties



Our principal office is located in Cambridge, Massachusetts.
We currently lease approximately 11,500 square feet of office and laboratory space at a monthly rate of $177,500 under a lease
that is due to expire in April 2018. We recently leased additional laboratory space concurrent with this lease for a monthly rate
of $50,000.



We have entered into a license agreement that commences May
2018 pursuant to which we will lease approximately 19,800 square feet of office and laboratory space in Cambridge, Massachusetts.
We expect to use this space as our new principal executive offices and for general office, research and development, and laboratory
uses. The monthly rent payments due under this license agreement will be approximately $297,500 for the first 18 months of the
term and increase to approximately $388,400 for the remaining 18 months of the term, which expires on April 30, 2021.



Item 3. Legal Proceedings



We are not currently a party to any pending legal proceedings
that we believe will have a material adverse effect on our business or financial conditions. We may, however, be subject to various
claims and legal actions arising in the ordinary course of business from time to time.

Stockholder Matters and Issuer Purchases of Equity Securities



Price Range and Holders of Common Stock



Our shares of common stock have been listed on the Nasdaq Capital
Market under the symbol “CUE” since January 2, 2018. Prior to that date, there was no public trading market for our
common stock.





On March 22, 2018 the last reported sale price of our common
stock was $16.47.



As of March 22, 2018, there were 203 holders of record of our

Dividend Policy



We have never paid cash dividends on our securities and we do
not anticipate paying any cash dividends on our shares of common stock in the foreseeable future. We intend to retain any future
earnings for reinvestment in our business. Any future determination to pay cash dividends will be at the discretion of our board
of directors, and will be dependent upon our financial condition, results of operations, capital requirements and such other factors
as our board of directors deems relevant.



Recent Sales of Unregistered Securities



The following represents a summary of unregistered securities
issued by the Company during the time period covered by this report. The Company issued these stock options exercisable for shares
of its common stock under its 2016 Omnibus Incentive Plan and 2016 Non-employee Equity Incentive Plan.



| | · | Effective March 15, 2017, we granted to certain employees options to purchase an aggregate of 173,000 shares of common stock
at an exercise price of $5.00 per share, each with a term of seven years and vesting over four years in eight equal semi-annual
installments.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Effective April 17, 2017, we granted to Ken Pienta, our Chief Medical Officer, options to purchase 150,000 shares of our common
stock at an exercise price of $5.00 per shares, with a term of seven years and vesting in annual installments over a four-year
period.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Effective June 14, 2017, we granted to certain employees options to purchase an aggregate of 220,000 shares of our common
stock at an exercise price of $5.00 per share, each with a term of seven years and vesting over four years in eight equal semi-annual
installments.
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Effective June 14, 2017, we granted to Peter Kiener, our Chairman, an option to purchase 60,000 shares of our common stock
at an exercise price of $5.00 per share, with a term of seven years and vesting over five years in equal annual installments.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Effective June 14, 2017, we granted to Ulrich Weidle, a senior scientific advisor, an option to purchase 100,000 shares
of our common stock at an exercise price of $5.00 per share, with a term of seven years and vesting over four years in equal annual
installments.
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Effective December 27, 2017, we granted to certain employees options to purchase an aggregate of 136,000 shares of common stock
at an exercise price of $7.50 per share, each with a term of seven years and vesting over four years in eight equal semi-annual
installments.
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



All of the stock options described above were granted in reliance
upon an available exemption from the registration requirements of the Securities Act, including those contained in Rule 701 promulgated
under Section 3(b) of the Securities Act. Among other things, we relied on the fact that, under Rule 701, companies that are not
subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act are exempt from registration under the
Securities Act with respect to certain offers and sales of securities pursuant to “compensatory benefit plans” as defined
under that rule. We believe that all of the options described above were issued pursuant qualifying “compensatory benefit
plans”.



46







Effective December 27, 2017, the Company granted to Colin Sandercock,
its Senior Vice President, General Counsel and Secretary, under its 2016 Omnibus Incentive Plan (i) an option to purchase 150,000
shares of our common stock at an exercise price of $7.50 per share, with a term of seven years and vesting over four years in eight
equal semi-annual installments and (ii) an option to purchase 100,000 shares of our common stock at an exercise price of $7.50
per share, with a term of seven years and vesting upon the achievement of certain performance goals. We intend to file a registration
statement on Form S-8 to register the issuance of the shares issuable upon exercise of these options prior to any such issuance
being made.



Use of Proceeds from Registered Securities



On December 14, 2017, our Registration Statement on Form S-1, as amended (File No. 333-220550), was declared
effective by the SEC and our Registration Statement on Form S-1 (File No. 333-222211) became effective upon filing with SEC on
December 21, 2017. These registration statements, collectively, registered a maximum aggregate $70,000,000 of our common stock
in connection with our initial public offering, pursuant to which we sold 8,820,710 shares of common stock at a price to the public
of $7.50 per share. The offering closed on December 27, 2017, generating net proceeds of approximately $61.9 million after deducting
underwriting commissions of approximately $3.5 million and other offering expenses of $830,000 payable by us. The offering terminated
before all of the securities registered on the registration statements had been sold. MDB Capital Group, LLC, of which Christopher
Marlett and Anthony DiGiandomenico, are co-founders and owners, served as the underwriter for the offering. No payments were made
by us, directly or indirectly, to directors, officers or persons owning ten percent or more of our common stock or to their associates,
or to our affiliates, other than underwriting commission paid to MDB Capital Group and payments in the ordinary course of business
to officers for salaries and to non-employee directors as compensation for board or board committee service.



There has been no material change in the planned use of proceeds
from our initial public offering as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities
Act of 1933, as amended, on December 21, 2017.

Item 7. Management’s Discussion and Analysis of Financial
Condition and Results of Operations



The following discussion of our financial condition and results
of operations should be read in conjunction with the financial statements and the related notes thereto included elsewhere in this
Annual Report on Form 10-K.



Overview



The Company is an innovative biopharmaceutical company developing
a novel and proprietary class of biologic drugs for the selective modulation of the human immune system to treat a broad range
of cancers and autoimmune disorders. The Company’s corporate offices and research facilities are located in Cambridge, Massachusetts.



The Company’s product candidates are currently in preclinical
development, and the Company’s activities are subject to significant risks and uncertainties. The Company has not yet commenced
any revenue-generating operations, does not have any cash flows from operations, and will need to raise additional capital to its
growth and ongoing business operations.



Plan of Operation



The Company’s technology is in the development phase.
The Company believes that its licensed platforms have the potential for creating a robust pipeline of drug candidates addressing
multiple medical indications. The Company intends to maximize the value and probability of commercialization of its CUE BiologicsTM
immunotherapeutics by focusing on research, testing, optimizing, conducting pilot studies, performing early stage clinical development
and partnering for more extensive, later stages of clinical development, as well as seeking extensive patent protection and intellectual
property development.



Since the Company is a development stage company, the majority
of its business activities to date and its planned future activities will be devoted to further research and development.



A fundamental part of the Company’s corporate development
strategy is to establish one or more strategic partnerships with leading pharmaceutical or biotechnology organizations that will
allow the Company to more fully exploit the potential of its technology platform, such as the one with Merck described below under
the heading “Collaboration Agreement with Merck.”



Critical Accounting Policies



The following discussion and analysis of financial condition
and results of operations is based upon the Company’s financial statements, which have been prepared in conformity with accounting
principles generally accepted in the United States of America (“GAAP”). Certain accounting policies and estimates are
particularly important to the understanding of the Company’s financial position and results of operations and require the
application of significant judgment by management or can be materially affected by changes from period to period in economic factors
or conditions that are outside of the Company’s control. As a result, these issues are subject to an inherent degree of uncertainty.
In applying these policies, management uses its judgment to determine the appropriate assumptions to be used in the determination
of certain estimates. Those estimates are based on the Company’s historical operations, the future business plans and the
projected financial results, the terms of existing contracts, trends in the industry, and information available from other outside
sources. For a more complete description of the Company’s significant accounting policies, see Note 3 to the financial statements
included in this report.



Research and Development Costs



Research and development expenses consist primarily of compensation
costs, fees paid to consultants, outside service providers and organizations (including research institutes at universities), facility
costs, and development and clinical trial costs with respect to the Company’s product candidates.



Research and development expenses incurred under contracts are
expensed ratably over the life of the underlying contracts, unless the achievement of milestones, the completion of contracted
work, or other information indicates that a different expensing schedule is more appropriate. Other research and development expenses
are charged to operations as incurred. Payments made pursuant to research and development contracts are initially recorded as research
and development contract advances in the Company’s balance sheet and then charged to research and development expenses in
the Company’s statement of operations as those contract services are performed. Expenses incurred under research and development
contracts in excess of amounts advanced are recorded as research and development contract liabilities in the Company’s balance
sheet, with a corresponding charge to research and development expenses in the Company’s statement of operations.



49







Nonrefundable advance payments for future research and development
activities pursuant to an executory contractual arrangement are recorded as advances as described above. Nonrefundable advance
payments are recognized as an expense as the related services are performed. The Company evaluates whether it expects the services
to be rendered at each quarter end and year end reporting date. If the Company does not expect the services to be rendered, the
advance payment is charged to expense. To the extent that a nonrefundable advance payment is for contracted services to be performed
within 12 months from the reporting date, such advance is included in current assets; otherwise, such advance is included in non-current
assets.



The Company evaluates the status of its research and development
agreements and contracts, and the carrying amount of the related assets and liabilities, at each quarter end and year end reporting
date, and adjusts the carrying amounts and their classification on the balance sheet as appropriate.



Research and Development Funding Arrangements



The Company’s proprietary biologics are at an early stage
and will require substantial time and funding to continue development. There can be no assurances that any of the Company’s
biologics will ultimately become commercially viable product candidates. In order to finance its research and development programs,
the Company may periodically enter into collaboration agreements with third parties that provide funding for certain aspects of
the Company’s ongoing research and development activities. The Company considers various factors in determining the appropriate
accounting treatment for such collaboration agreements, including, among others, the risks of and costs associated with the research
and development program being funded, the stage of development of the proprietary biologics subject to the research and development
program, the likelihood at initiation that the collaboration arrangement will result in an economically successful outcome to the
third party, the continuing involvement of the Company in the research and development program and the expenditure of the funds,
the transfer of the financial risk associated with the research and development program to the third party, the intended use of
the funds and any restrictions thereon, and the probability of any repayment obligations or other forms of consideration if the
proprietary biologics subject to the research and development program are not successfully developed and commercialized.



In accordance with ASC 730-20-25-8, to the extent that a collaboration
agreement results in a substantive and genuine transfer of financial risk to a third party funding source because any economic
benefit that the third party may receive depends solely on the research and development program successfully developing commercially
viable product candidates having future economic benefit (which is uncertain at the initiation of the collaboration agreement),
the Company will account for such collaboration agreement as a contract to perform research and development services for a third
party. The funds received from the third party under such a collaboration agreement will initially be recorded as a deferred credit
in the Company’s balance sheet. As the related contractual research and development costs are incurred, the applicable amount
of the deferred credit will be credited to operations and will be classified as an offset to such research and development costs
in the Company’s statement of operations.



Patent Expenses



The Company is the exclusive worldwide licensee of, and has
patent applications pending for, numerous domestic and foreign patents. Due to the significant uncertainty associated with the
successful development of one or more commercially viable product candidates based on the Company’s research efforts and
any related patent applications, all patent costs, including patent-related legal fees, filing fees and other costs are charged
to operations as incurred. Patent expenses are included in general and administrative expenses in the Company’s statement
of operations.



Reclassification



Certain comparative figures for the years ended 2016 and 2015
have been adjusted to correct the classification of patent legal costs and intellectual property management fees from research
and development expenses to general and administrative expenses. During the years ended December 31, 2016 and 2015, patent
legal costs of $366,131 and $178,697, and intellectual property management fees of $90,000 and $38,182, aggregating $456,131
and $216,879, respectively, were reclassified from research and development costs to general and administrative costs. These changes
did not impact loss from operations or net loss.



50







Licensing Fees and Costs



Licensing fees and costs consist primarily of costs relating
to the acquisition of the Company’s license agreement with the Albert Einstein College of Medicine, a division of Yeshiva
University (“Einstein”), including related royalties, maintenance fees, milestone payments and product development
costs. Licensing fees and costs are charged to operations as incurred.



Stock-Based Compensation



The Company periodically issues stock options to officers, directors,
employees, Scientific and Clinical Advisory Board members, non-employees and consultants for services rendered. Such issuances
vest and expire according to terms established at the issuance date.



Stock-based payments to officers, directors and employees, including
grants of employee stock options, are recognized in the financial statements based on their grant date fair values. Stock option
grants, which are generally time-vested, are measured at the grant date fair value and charged to operations on a straight-line
basis over the vesting period. The fair value of stock options is determined utilizing the Black-Scholes option-pricing model,
which is affected by several variables, including the risk-free interest rate, the expected dividend yield, the life of the equity
award, the exercise price of the stock option as compared to the fair value of the common stock on the grant date, and the estimated
volatility of the common stock over the term of the equity award.1



Stock options granted to members of the Company’s Scientific
and Clinical Advisory Board, non-employees and outside advisors and consultants are revalued each reporting period to determine
the amount to be recorded as an expense in the respective period. As the stock options vest, they are valued on each vesting date
and an adjustment is recorded for the difference between the value already recorded and the value on the date of vesting.



The risk-free interest rate is based on the U.S. Treasury yield
curve in effect at the time of grant. Until the Company has established a trading market for its common stock, estimated volatility
is based on the average historical volatilities of comparable public companies in a similar industry. The expected dividend yield
is based on the current yield at the grant date; the Company has never declared or paid dividends and has no plans to do so for
the foreseeable future. As permitted by Staff Accounting Bulletin No. 107, due to the Company’s lack of history and option
activity, management utilizes the simplified method to estimate the expected term of options at the date of grant. The fair value
of common stock is determined by reference to either recent or anticipated cash transactions involving the sale of the Company’s
common stock.



The Company recognizes the fair value of stock-based compensation
in general and administrative expenses and in research and development expenses in the Company’s statement of operations,
depending on the type of services provided by the recipient of the equity award. The Company issues new shares of common stock
to satisfy stock option exercises.



Income Taxes



The Company accounts for income taxes under an asset and liability
approach for financial accounting and reporting for income taxes. Accordingly, the Company recognizes deferred tax assets and liabilities
for the expected impact of differences between the financial statements and the tax basis of assets and liabilities.





The Company accounts for uncertainties in income tax law under a comprehensive model for the financial statement recognition,
measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as
prescribed by GAAP. The tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained
by the taxing authority as of the reporting date. If the tax position is not considered “more-likely-than-not”
to be sustained, then no benefits of the position are recognized.



51







The Company records a valuation allowance to reduce its deferred
tax assets to the amount that is more likely than not to be realized. In the event the Company was to determine that it would be
able to realize its deferred tax assets in the future in excess of its recorded amount, an adjustment to the deferred tax assets
would be credited to operations in the period such determination was made. Likewise, should the Company determine that it would
not be able to realize all or part of its deferred tax assets in the future, an adjustment to the deferred tax assets would be
charged to operations in the period such determination was made.



The Company is subject to U.S. Federal and Massachusetts state
income taxes. As the Company’s net operating losses have yet to be utilized, all previous tax years remain open to examination
by Federal and state taxing authorities in which the Company currently operates.



The Company recognizes interest accrued relative to unrecognized
tax benefits in interest expense and penalties in operating expense.



Recent Accounting Pronouncements



In May 2014, the Financial Accounting Standards Board (“FASB”)
issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09
will eliminate transaction- and industry-specific revenue recognition guidance under current GAAP and replace it with a principle
based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value
of transferred goods or services as they occur in the contract. ASU 2014-09 also will require additional disclosure about the nature,
amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes
in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The FASB has issued ASU 2016-08, ASU 2016-10,
ASU 2016-11, ASU 2016-12, and ASU 2016-20, all of which clarify certain implementation guidance within ASU 2014-09. ASU 2014-09
is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. Entities will be able
to transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company
will adopt the provisions of ASU 2014-09 in the quarter beginning January 1, 2018. As the Company is unlikely to generate
any sustainable operating revenues in the next several years, the adoption of ASU 2014-09 is not currently expected to have any
impact on the Company’s financial statement presentation or disclosures.



In November 2015, the FASB issued Accounting Standards
Update No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). ASU 2015-17
requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position.
ASU 2015-17 was effective for financial statements issued for annual periods beginning after December 15, 2016, and interim
periods within those annual periods. Earlier application is permitted as of the beginning of an interim or annual reporting period.
The Company adopted the provisions of ASU 2015-17 in the quarter beginning January 1, 2017. The adoption of ASU 2015-17 did
not have any impact on Company’s financial statement presentation or disclosures.



In February 2016, the FASB issued Accounting Standards
Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 requires a lessee to record a right-of-use asset
and a corresponding lease liability, initially measured at the present value of the lease payments, on the balance sheet for all
leases with terms longer than 12 months, as well as the disclosure of key information about leasing arrangements. ASU 2016-02 requires
recognition in the statement of operations of a single lease cost, calculated so that the cost of the lease is allocated over the
lease term, generally on a straight-line basis. ASU 2016-02 requires classification of all cash payments within operating activities
in the statement of cash flows. Disclosures are required to provide the amount, timing and uncertainty of cash flows arising from
leases. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered
into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients
available. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those
fiscal years. Early application is permitted. The Company will adopt the provisions of ASU 2016-02 in the quarter beginning January 1,
2019. The Company generally does not finance purchases of property and equipment, but does lease its operating facilities. While
the Company is continuing to assess the potential impact of ASU 2016-02, it currently expects that most of its lease commitments
will be subject to ASU 2016-02 and accordingly, upon adoption will be recognized as lease liabilities and right-of-use assets in
the Company’s balance sheet.



In March 2016, the FASB issued Accounting Standards Update
No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU
2016-09”). ASU 2016-09 requires, among other things, that all income tax effects of awards be recognized in the statement
of operations when the awards vest or are settled. ASU 2016-09 also allows for an employer to repurchase more of an employee’s
shares than it can today for tax withholding purposes without triggering liability accounting and allows for a policy election
to account for forfeitures as they occur. ASU 2016-09 was effective for fiscal years beginning after December 15, 2016, including
interim periods within those fiscal years. Early adoption is permitted for any entity in any interim or annual period. The Company
adopted the provisions of ASU 2016-09 in the quarter beginning January 1, 2017. The adoption of ASU 2016-09 did not have any
impact on the Company’s financial statement presentation or disclosures.



52







In July 2017, the FASB issued Accounting Standards Update
No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic
815): (Part I) Accounting for Certain Financial Instruments with Down Round Features; (Part II) Replacement of the Indefinite Deferral
for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling
Interests with a Scope Exception (“ASU 2017-11”). ASU 2017-11 allows companies to exclude a down round feature when
determining whether a financial instrument (or embedded conversion feature) is considered indexed to the entity’s own stock.
As a result, financial instruments (or embedded conversion features) with down round features may no longer be required to be accounted
for as derivative liabilities. A company will recognize the value of a down round feature only when it is triggered and the strike
price has been adjusted downward. For equity-classified freestanding financial instruments, an entity will treat the value of the
effect of the down round as a dividend and a reduction of income available to common shareholders in computing basic earnings per
share. For convertible instruments with embedded conversion features containing down round provisions, entities will recognize
the value of the down round as a beneficial conversion discount to be amortized to earnings. ASU 2017-11 is effective for fiscal
years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The guidance
in ASU 2017-11 can be applied using a full or modified retrospective approach. The adoption of ASU 2017-11 is not currently expected
to have any impact on the Company’s financial statement presentation or disclosures.



Management does not believe that any other recently issued,
but not yet effective, authoritative guidance, if currently adopted, would have a material impact on the Company’s financial
statement presentation or disclosures.



Acquisition of Trademark



On May 4, 2017, the Company entered into a settlement agreement
with Cue BioLogics, LLC, an unrelated party, to acquire all right, title and interest in and to the CUE BIOLOGICS mark, and any
derivative mark incorporating CUE, throughout the world, together with all associated goodwill and common law rights appurtenant
thereto, including, but not limited to, any right, title and interest in any corporate name, company name, business name, trade
name, dba, domain name, or other source identifier incorporating CUE (collectively, the “CUE BIOLOGICS Mark”), in exchange
for a cash payment by the Company of  $175,000.



Accounting Standards Codification (“ASC”) 350-30-20
defines a defensive intangible asset as an acquired intangible asset in a situation in which an entity does not intend to actively
use the asset but intends to hold (lock up) the asset to prevent others from obtaining access to the asset. The Company determined
that the acquired intangible asset met the definition of a defensive intangible asset and has therefore accounted for the $175,000
payment to Cue BioLogics, LLC for the CUE BIOLOGICS Mark as an acquired intangible asset.



As the Company can renew the underlying rights to the CUE BIOLOGICS
trademark indefinitely at nominal cost, this acquired intangible asset has been classified as a non-amortizable intangible asset
in Company’s balance sheet at December 31, 2017. The Company evaluates the status of this intangible asset for amortization
and impairment at each quarter end and year end reporting date.



Significant Contracts and Agreements Related to
Research and Development Activities



License Agreement



On January 14, 2015, the Company entered into a license
agreement, as amended and restated on July 31, 2017 (the “Einstein License”), with Einstein for certain patent
rights (the “Patents”) relating to the Company’s core technology platform for the engineering of biologics to
control T cell activity, precision, immune-modulatory drug candidates, and two supporting technologies that enable the discovery
of costimulatory signaling molecules (ligands) and T cell targeting peptides.



53







The Company holds an exclusive worldwide license, with the right
to sublicense, import, make, have made, use, provide, offer to sell, and sell all products, processes and services that use the
patents covered by the Einstein License, including certain technology received from Einstein related thereto (the “Licensed
Products”). Under the Einstein License, the Company is required to:



| | · | Pay royalties based on certain percentage of proceeds, as defined in the Einstein License, from sales of Licensed Products,
including sublicense agreements.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Pay escalating annual maintenance fees, which are non-refundable, but are creditable against the amount due to Einstein for
royalties.
| | - | --------------------------------------------------------------------------------------------------------------------------------------



| | · | Make significant payments based upon the achievement of certain milestones, as defined in the Einstein License. At December
31, 2017, none of these milestones had been achieved by the Company.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Incur minimum product development costs per year until the first commercial sale of the first Licensed Product.
| | - | ---------------------------------------------------------------------------------------------------------------



The Company was in compliance with its obligations under the
Einstein License at December 31, 2017 and 2016.



The Einstein License expires upon the expiration of the last
obligation to make royalty payments to Einstein which may be due with respect to certain Licensed Products, unless terminated earlier
under the provisions thereof. The Einstein License includes certain termination provisions if the Company fails to meet its obligations
thereunder.



The Company accounts for the costs incurred in connection with
the Einstein License in accordance with ASC 730, Research and Development. For the years ended December 31, 2017, 2016, and
2015, costs incurred with respect to the Einstein License aggregated $5,084,708, $31,250, and $127,336 respectively. Such costs
are included in research and development costs in the statements of operations.



Pursuant to the Einstein License, the Company issued to Einstein
671,572 shares of common stock of the Company in connection with the consummation of the initial public offering of its common
stock on December 27, 2017. Under the Einstein License, the Company must also use its best efforts to file a registration
statement covering the resale of the 671,572 shares issued to Einstein no later than 180 days after the consummation of such offering.



The Company accounted for the issuance of these shares in accordance
with ASC 730, Research and Development, as a charge to research and development expenses in the statements of operations at their
aggregate fair value of $5,036,789, as the Patents acquired from Einstein are for use in the Company’s research and development
activities exclusively with respect to its core technology platform, have no alternative future use by the Company, and therefore
no separate economic value.



Service Agreement



On October 1, 2015, the Company entered into a service
agreement (the “Service Agreement”) with Einstein to support the Company’s ongoing research and development activities.
The initial term of the Service Agreement was for three months, which was amended in February 2016 to extend it for the period
of time deemed necessary to complete the services pursuant to the terms of the Service Agreement. For the years ended December 31,
2017, 2016, and 2015, costs incurred with respect to the Service Agreement aggregated $0, $80,000, and $200,000, respectively.
Such costs are included in research and development expenses in the statements of operations.



Agreements with Catalent Pharma Solutions, LLC



Catalent Pharma Solutions, LLC (“Catalent”) is a
global provider of drug delivery technology and development solutions for drugs, biologics and consumer health products.



On March 7, 2017, the Company entered into an agreement
with Catalent for Catalent to provide services on a sequential milestone basis with respect to the development and manufacture
of the Company’s lead drug candidate, CUE-101. The services under the agreement are designed to support the preparation and
filing of an Investigational New Drug Application with the United States Food and Drug Administration to allow for the commencement
of a Phase 1 clinical trial of CUE-101 in the United States. The Company incurred total direct costs under this agreement aggregating
$2.4 million during the year ended December 31, 2017 and currently estimates that it will incur an additional $2.4 of such costs
during the year ended December 31, 2018. The Company expects that certain of these payments will consist of nonrefundable
advance payments for which the Company anticipates receiving the contracted services within 12 months from the date of payment.
Management periodically reviews and updates the project’s estimated budget and timeline.



54







On July 5, 2017, the Company entered into a separate Master
Services Agreement with Catalent that outlines the terms and conditions under which Catalent will provide contract services with
respect to the Company’s research and development activities for a period of five years. The Company may terminate this agreement
without cause upon 90 days’ prior written notice. Unless and until terminated, this agreement will automatically be extended
for successive one-year periods.





With respect to the $2.4 million of total direct costs the Company
had incurred as of December 31, 2017, $1.6 million was charged to research and development expenses in the statement of operations
for the year ended December 31, 2017, representing 8.4% of research and development expenses for such period. The remaining $0.8
million of such costs estimated to be incurred is reflected as research and development contract advances in the condensed balance
sheet at December 31, 2017. The Company expects to receive the services related to such advance payments by May 31, 2018.
Accordingly, advance payments at December 31, 2017 are classified as a current asset and are expected to be charged to research
and development expenses in the statement of operations through June 30, 2018.



Collaboration Agreement with Merck



On November 14, 2017, we entered into an Exclusive Patent License
and Research Collaboration Agreement (the “Collaboration Agreement”) with Merck Sharp & Dohme Corp. (“Merck”)
for a partnership to research and develop certain of our proprietary biologics that target certain autoimmune disease indications
(the “Initial Indications”). We view this Collaboration Agreement as a component of our development strategy since
it will allow us to advance our autoimmune programs in partnership with a world class pharmaceutical company, while also continuing
our focus on our more advanced cancer programs. The research program outlined in the Collaboration Agreement entails (1) our research,
discovery and development of certain CUE BiologicsTM drug candidates up to the point of demonstration of certain biologically
relevant effects (“Proof of Mechanism”) and (2) the further development by Merck of the CUE BiologicsTM drug candidates
that have demonstrated Proof of Mechanism (the “Proposed Product Candidates”) up to the point of demonstration of all
or substantially all of the properties outlined in such Proposed Product Candidates’ profiles as described in the Collaboration
Agreement.



For the purposes of this collaboration, we have granted to Merck
under the Collaboration Agreement an exclusive license under certain of our patent rights, including a sublicense of patent rights
licensed from Einstein, to the extent applicable to the specific CUE BiologicsTM that are elected to be developed by Merck.
From the effective date of the Collaboration Agreement until the earlier of  (i) the first achievement of Proof of Mechanism
for a CUE BiologicsTM drug candidate or (ii) 18 months after we notify the joint steering committee that the first Product
Candidate has been synthesized under the research program, we are required to forebear from researching, developing or licensing
to a third party rights related to any CUE BiologicsTM drug candidate for the treatment of autoimmune diseases other than
pursuant to the Collaboration Agreement. In addition, so long as Merck continues product development on a Proposed Product Candidate,
we are restricted from conducting any development activities within the Initial Indication covered by such Proposed Product Candidate
other than pursuant to the Collaboration Agreement. The Company is not required to forbear at any time, however, from developing
other CUE BiologicsTM for use in therapeutic areas other than autoimmune diseases, e.g., for use in treating cancer or infectious
diseases.



In exchange for the licenses and other rights granted to Merck
under the Collaboration Agreement, Merck paid to us a $2.5 million nonrefundable up-front payment. Additionally, we may be eligible
to receive funding in developmental milestone payments, as well as tiered royalties, if all research, development, regulatory and
commercial milestones agreed upon by both parties are successfully achieved. Excluding the up-front payment described above, we
are eligible to earn up to $101 million for the achievement of certain research and development milestones, $120 million for the
achievement of certain regulatory milestones and $150 million for the achievement of certain commercial milestones, in addition
to tiered royalties on sales, if all pre-specified milestones associated with multiple products across the primary disease indication
areas are achieved. The Collaboration Agreement requires us to use the first $2.7 million of milestone payments we receive under
the agreement to fund contract research. The amount of the royalty payments is a percentage of product sales ranging in the single
digits based on the amount of such sales.



55







The term of the Collaboration Agreement extends until the expiration
of all royalty obligations following a product candidate’s receipt of marketing authorization, at which point Merck’s
licenses and sublicenses granted under the agreement shall become fully paid-up, perpetual licenses and sublicenses, as applicable.
Royalties on each product subject to the Collaboration Agreement shall continue on a country-by-country basis until the expiration
of the later of: (1) the last-to-expire patent claiming the compound on which such product is based and (2) a period of ten years
after the first commercial sale of such product in such country.



Notwithstanding the foregoing, Merck may terminate the Collaboration
Agreement at any time upon 30 days’ notice to the Company. The Collaboration Agreement may also be terminated by either party
if the other party is in breach of its obligations thereunder and fails to cure such breach within 90 days after notice or by either
party if the other party files for bankruptcy or other similar insolvency proceedings.



Results of Operations



Operating Expenses



The Company generally recognizes operating expenses as they
are incurred in two general categories, general and administrative expenses and research and development expenses. The Company’s
operating expenses also include non-cash components related to depreciation and amortization of property and equipment and stock-based
compensation, which are allocated, as appropriate, to general and administrative expenses and research and development expenses.



General and administrative expenses consist of salaries and
related expenses for executive, legal, finance, human resources, information technology and administrative personnel, as well as
professional fees, insurance costs, and other general corporate expenses. Management expects general and administrative expenses
to increase in future periods as the Company adds personnel and incurs additional expenses related to an expansion of its research
and development activities and its operation as a public company, including higher legal, accounting, insurance, compliance, compensation
and other expenses.



Research and development expenses consist primarily of compensation
expenses, fees paid to consultants, outside service providers and organizations (including research institutes at universities),
facility expenses, and development and clinical trial expenses with respect to the Company’s product candidates. The Company
charges research and development expenses to operations as they are incurred. Management expects research and development expenses
to increase in the future as the Company increases its efforts to develop technology for potential future products based on its
technology and research.



Years Ended December 31, 2017, 2016 and 2015



The Company’s statements of operations for the years ended
December 31, 2017, 2016, and 2015 as discussed herein are presented below.

General and Administrative



General and administrative expenses totaled $4,333,542 and $1,970,488
for the years ended December 31, 2017 and 2016, respectively. This increase of $2,363,054 was due primarily to the
growth of the Company and its activities. We expect our general and administrative expenses to continue to increase as we expand
our operations. General and administrative expenses for the year ended December 31, 2017 consisted of expenses related to

Liquidity and Capital Resources—December 31,
2017 and December 31, 2016



The Company has financed its working capital requirements primarily
through private and public offerings of equity securities and cash received in December 2017 from Merck in connection with the
Collaboration Agreement. At December 31, 2017 and December 31, 2016, the Company had cash and a certificate of deposit totaling
$63,583,717 and $14,975,853, respectively, available to fund the Company’s ongoing business activities. Additional information
concerning the Company’s financial condition and results of operations is provided in the financial statements included in
this report.



The amounts that the Company actually spends for any specific
purpose may vary significantly and will depend on a number of factors, including, but not limited to, the Company’s research
and development activities and programs, clinical testing, regulatory approval, market conditions, and changes in or revisions
to the Company’s business strategy and technology development plans. Investors will be relying on the judgment of the Company’s
management regarding the application of the proceeds from the sale of the Company’s common stock.



The Company believes that its existing cash resources will be
sufficient to fund the Company’s projected operating requirements for at least the next 12 months based on current operating
plans. Until the Company is able to generate sustainable revenues that generate operating profitability and positive operating
cash flows, the Company expects to finance its future cash needs through public or private equity offerings, debt financings or
corporate collaboration and licensing arrangements. However, there can be no assurances that the Company will be able to obtain
additional financing on acceptable terms and in the amounts necessary to fully fund its future operating requirements, if at all.
If the Company is unable to obtain sufficient cash resources to fund its operations, the Company may be forced to reduce or discontinue
its operations entirely.



If the Company issues additional equity securities to raise
funds, the ownership percentage of the Company’s existing stockholders would be reduced. New investors may demand rights,
preferences or privileges senior to those of existing holders of the Company’s common stock. If the Company issues debt securities,
the Company may be required to grant security interests in its assets, could have substantial debt service obligations, and lenders
may have a senior position (compared to stockholders) in any potential future bankruptcy or liquidation of the Company. Additionally,
corporate collaboration and licensing arrangements may require us to incur non-recurring and other charges, give up certain rights
relating to our intellectual property and research and development activities, increase our near and long-term expenditures, issue
securities that dilute our existing stockholders, issue debt which may require liens on our assets and which will increase our
monthly expense obligations, or disrupt our management and business.



Operating Activities



During the year ended December 31, 2017, the Company used
cash of $12,191,514 in operating activities, as compared to $5,968,411 in operating activities during the year ended December 31,
2016. The difference between cash used in operating activities and net loss consisted primarily of depreciation and amortization,
stock-based compensation, and changes in operating assets and liabilities, and $5,036,789 attributable to the issuance of common
stock to Albert Einstein University pursuant to the Einstein license agreement.



58







Investing Activities



During the year ended December 31, 2017, the Company used cash
of $1,204,977 in investing activities, consisting of $1,029,942 for the purchase of office and laboratory equipment,
$175,000 for the purchase of the CUE BIOLOGICS Mark and $35 with respect to interest earned on the certificate of deposit. During
the year ended December 31, 2016, the Company used cash of $516,012 in investing activities, consisting of $515,979
for the purchase of office and laboratory equipment and $33 with respect to interest earned on the certificate of deposit.



Financing Activities



During the year ended December 31, 2017, the Company generated
cash from financing activities of $62,004,320, consisting of the net proceeds from the Company’s initial public offering
and $61,995,312, $8,008 from the exercise of stock options, $1,000 from the sale of underwriters warrants. During the year ended
December 31, 2016, the Company generated cash from financing activities of $15,005,036, consisting of the net proceeds from
the December 2016 common stock private placement.

Off-Balance Sheet Transactions



At December 31, 2017, the Company did not have any transactions,
obligations or relationships that could be considered off-balance sheet arrangements.



Item 7A. Quantitative and Qualitative Disclosures About
Market Risk.



Market risk represents the risk of loss that may result from
the change in value of financial instruments due to fluctuations in their market price. Market risk is inherent in all financial
instruments. The primary quantifiable market risk associated with our financial instruments is sensitivity to changes in interest
rates. Interest rate risk represents the potential loss from adverse changes in market interest rates. The primary objective of
our investment activities is to preserve principal while maximizing our income from investments and minimizing our market risk.
As of December 31, 2017, our portfolio of financial instruments consisted of cash and certificates of deposit. Due to the short
term nature of these financial instruments, we believe there is no material exposure to interest rate risk, and/or credit risk,
arising from our portfolio of financial instruments.



Our assets and liabilities are denominated in U.S. dollars.
Consequently, we have not considered it necessary to use foreign currency contracts or other derivative instruments to manage
changes in currency rates. We do not now, nor do we plan to, use derivative financial instruments for speculative or trading purposes.
However, these circumstances might change.

REPORT OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM



To the Board of Directors and Stockholders
of

Cue Biopharma, Inc.



Opinion on the Financial Statements

We have audited the accompanying
balance sheets of Cue Biopharma, Inc. (the “Company”) as of December 31, 2017 and 2016, and the related
statements of operations, stockholders’ equity and cash flows, for each of the three years in the period ended December
31, 2017, and the related notes (collectively referred to as the “financial statements”). In our opinion, the
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017
and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31,
2017, in conformity with accounting principles generally accepted in the United States of America.



Basis for Opinion

These financial statements are the responsibility
of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits.
We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”)
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable
rules and regulations of the Securities and Exchange Commission and the PCAOB.



We conducted our audits in accordance
with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required
to have, nor were we engaged to perform an audit of its internal control over financial reporting. As part of our audits, we are
required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion
on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.



Our audits included performing procedures
to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a
reasonable basis for our opinion.

We have served as the Company’s auditor
since 2016.

CUE BIOPHARMA, INC.



NOTES TO FINANCIAL STATEMENTS

Years Ended December 31, 2017, 2016
and 2015



| | 1. | Organization and Basis of Presentation
| | -- | --------------------------------------



Cue Biopharma, Inc. (the “Company”)
was incorporated in the State of Delaware on December 31, 2014 under the name Imagen Biopharma, Inc., and completed its organization,
formation and initial capitalization activities effective as of January 1, 2015. In October 2016, the Company changed
its name to Cue Biopharma, Inc. The Company’s corporate office and research facilities are located in Cambridge, Massachusetts.



On January 14, 2015, in order to implement
its business plans, the Company entered into a license agreement with the Albert Einstein College of Medicine, a division of Yeshiva
University (“Einstein”), for certain patent rights, as described in Note 5.



The Company is a pre-clinical biopharmaceutical
company that is developing a novel and proprietary class of biologic drugs for the selective modulation of the human immune system
to treat a broad range of cancers and autoimmune disorders.



Reclassifications



Certain comparative figures for the years
ended 2016 and 2015 have been adjusted to correct the classification of patent legal costs and intellectual property management
fees from research and development expenses to general and administrative expenses. During the years ended December 31, 2016
and 2015, patent legal costs of  $366,131 and $178,697 and intellectual property management fees of $90,000 and $38,182,
aggregating $456,131 and $216,879, respectively, were reclassified from research and development costs to general and administrative
costs. These changes did not impact loss from operations or net loss.



Risks and Uncertainties



The Company’s operations are subject
to a number of factors that may affect its operating results and financial condition. Such factors include, but are not limited
to: the Company’s ability to determine candidates for clinical testing, the results of clinical testing and trial activities
of the Company’s product candidates, the Company’s ability to obtain regulatory approval to market its product candidates,
the Company’s intellectual property, competition from products manufactured and sold or being developed by other companies,
the price of, and demand for, the Company’s product candidates if approved for sale, the Company’s ability to negotiate
favorable licensing or other manufacturing and marketing agreements for its product candidates, and the Company’s ability
to raise capital.



The Company currently has no commercially
approved product candidates and there can be no assurance that the Company’s research and development programs will be successfully
commercialized. Developing and commercializing a product requires significant time and capital and is subject to regulatory review
and approval, as well as competition from other biotechnology and pharmaceutical companies. The Company operates in an environment
of rapid change and is dependent upon the continued services of its employees and consultants and obtaining and protecting its
intellectual property.



| | 2. | Initial Public Offering
| | -- | -----------------------



On December 27, 2017, the Company completed
an initial public offering (“IPO”) of its common stock, which resulted in the sale of 8,820,710 shares of common stock
at a price to the public of $7.50 per share. The Company received net proceeds from the IPO of $61.9 million after deducting underwriting
discounts, commissions, and offering costs incurred by the Company.



| | 3. | Summary of Significant Accounting Policies
| | -- | ------------------------------------------



Use of Estimates



The preparation of financial statements in
conformity with United States Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported
amounts of expenses during the reporting period. Significant estimates include the accounting for potential liabilities, the assumptions
utilized in valuing stock-based compensation issued for services, the realization of deferred tax assets, and the impairment of
long-lived assets and intangibles. Actual results could differ from those estimates.



F-7







Cash Concentrations



The Company maintains its cash balances with
a financial institution in Federally-insured accounts and may periodically have cash balances in excess of insurance limits. The
Company maintains its accounts with a financial institution with a high credit rating. The Company has not experienced any losses
to date and believes that it is not exposed to any significant credit risk on cash.



Restricted Cash

The Company purchased a $50,000 certificate
of deposit to collateralize a credit card account with a commercial bank that was classified as short-term certificate of deposit
as of December 31, 2017 and 2016.



Property and Equipment



Property and equipment is recorded at cost.
Major improvements are capitalized, while maintenance and repairs are charged to expense as incurred. Gains and losses from disposition
of property and equipment are included in income and expense when realized. Amortization of leasehold improvements is provided
using the straight-line method over the shorter of the lease term or the useful life of the underlying assets. Depreciation of
property and equipment is provided using the straight-line method over the following estimated useful lives:



|Laboratory equipment   |  |  | 5 years   | 
|---------------------- |  |  | --------- | 
|                       |  |  |           | 
|Computer equipment     |  |  | 3 years   | 
|                       |  |  |           | 
|Furniture and fixtures |  |  | 3-8 years | 



The Company recognizes depreciation and amortization
expense in general and administrative expenses and in research and development expenses in the Company’s statements of operations,
depending on how each category of property and equipment is utilized in the Company’s business activities.



Trademark



Trademark consists of the Company’s
right, title and interest in and to the CUE BIOLOGICS Mark, and any derivative mark incorporating CUE, throughout the world, together
with all associated goodwill and common law rights appurtenant thereto, including, but not limited to, any right, title and interest
in any corporate name, company name, business name, trade name, dba, domain name, or other source identifier incorporating CUE.



As the Company can renew the underlying rights
to the CUE BIOLOGICS Mark indefinitely at nominal cost, this acquired intangible asset has been classified as a non-amortizable
intangible asset in the Company’s balance sheet at December 31, 2017. The Company evaluates the status of this intangible
asset for amortization and impairment at each quarter end and year end reporting date.



Research and Development
Funding Arrangements



The Company’s proprietary biologics
are at an early stage and will require substantial time and funding to continue development. There can be no assurances that any
of the Company’s biologics will ultimately become commercially viable product candidates. In order to finance its research
and development programs, the Company may periodically enter into collaboration agreements with third parties that provide funding
for certain aspects of the Company’s ongoing research and development activities. The Company considers various factors in
determining the appropriate accounting treatment for such collaboration agreements, including, among others, the risks of and costs
associated with the research and development program being funded, the stage of development of the proprietary biologics subject
to the research and development program, the likelihood at initiation that the collaboration arrangement will result in an economically
successful outcome to the third party, the continuing involvement of the Company in the research and development program and the
expenditure of the funds, the transfer of the financial risk associated with the research and development program to the third
party, the intended use of the funds and any restrictions thereon, and the probability of any repayment obligations or other forms
of consideration if the proprietary biologics subject to the research and development program are not successfully developed and
commercialized.



F-8







In accordance with ASC 730-20-25-8, to the
extent that a collaboration agreement results in a substantive and genuine transfer of financial risk to a third party funding
source because any economic benefit that the third party may receive depends solely on the research and development program successfully
developing commercially viable product candidates having future economic benefit (which is uncertain at the initiation of the collaboration
agreement), the Company will account for such collaboration agreement as a contract to perform research and development services
for a third party. The funds received from the third party under such a collaboration agreement will initially be recorded as a
deferred credit in the Company’s balance sheet. As the related contractual research and development costs are incurred, the
applicable amount of the deferred credit will be credited to operations and will be classified as an offset to such research and
development costs in the Company’s statement of operations.



Research and Development
Expenses



Research and development expenses consist
primarily of compensation costs, fees paid to consultants, outside service providers and organizations (including research institutes
at universities), facility costs, and development and clinical trial costs with respect to the Company’s product candidates.



Research and development expenses incurred
under contracts are expensed ratably over the life of the underlying contracts, unless the achievement of milestones, the completion
of contracted work, or other information indicates that a different expensing schedule is more appropriate. Other research and
development expenses are charged to operations as incurred.



F-9







Payments made pursuant to research and development
contracts are initially recorded as research and development contract advances in the Company’s balance sheet and then charged
to research and development expenses in the Company’s statement of operations as those contract services are performed. Expenses
incurred under research and development contracts in excess of amounts advanced are recorded as research and development contract
liabilities in the Company’s balance sheet, with a corresponding charge to research and development expenses in the Company’s
statement of operations.



Nonrefundable advance payments for future
research and development activities pursuant to an executory contractual arrangement are recorded as advances as described above.
Nonrefundable advance payments are recognized as an expense as the related services are performed. The Company evaluates whether
it expects the services to be rendered at each quarter end and year end reporting date. If the Company does not expect the services
to be rendered, the advance payment is charged to expense. To the extent that a nonrefundable advance payment is for contracted
services to be performed within 12 months from the reporting date, such advance is included in current assets; otherwise, such
advance is included in non-current assets.



The Company evaluates the status of its research
and development agreements and contracts, and the carrying amount of the related assets and liabilities, at each quarter end and
year end reporting date, and adjusts the carrying amounts and their classification on the balance sheet as appropriate.



Patent Expenses



The Company is the exclusive worldwide licensee
of, and has patent applications pending for, numerous domestic and foreign patents. Due to the significant uncertainty associated
with the successful development of one or more commercially viable product candidates based on the Company’s research efforts
and any related patent applications, all patent costs, including patent-related legal fees, filing fees and other costs are charged
to operations as incurred. For the years ended December 31, 2017, 2016, and 2015, patent expenses were $592,262, $366,131,
and $178,697, respectively. Patent expenses are included in general and administrative expenses in the Company’s statement
of operations.



Licensing Fees and Costs



Licensing fees and costs consist primarily
of costs relating to the acquisition of the Company’s license agreement with Einstein, including related royalties, maintenance
fees, milestone payments and product development costs. Licensing fees and costs are charged to operations as incurred.



Long-Lived Assets



The Company reviews long-lived assets, consisting
of property and equipment, for impairment at each fiscal year end or when events or changes in circumstances indicate the carrying
value of these assets may exceed their current fair values. Recoverability of assets to be held and used is measured by a comparison
of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the
carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which
the carrying amount of the asset exceeds the fair value of the assets. Assets to be disposed of are separately presented in the
balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated.
The Company has not historically recorded any impairment to its long-lived assets. In the future, if events or market conditions
affect the estimated fair value to the extent that a long-lived asset is impaired, the Company will adjust the carrying value of
these long-lived assets in the period in which the impairment occurs. During the years ended December 31, 2017, 2016 and 2015
the company disposed of equipment totaling $15,993, $0 and $0, resulting in a loss of $10,677, $0 and $0, respectively.



Rent Expense and Deferred Rent Liability



Operating lease agreements which contain
provisions for future rent increases or periods in which rent payments are reduced or abated are recorded in monthly rent expense
in the amount of the total payments over the lease term divided by the number of months of the lease term. The difference between
rent expense recorded and the amount paid is credited or charged to a deferred rent liability account. The current portion of deferred
rent is included in current liabilities, and the remaining amount is shown in the balance sheet as a non-current liability. Accordingly,
rent expense is recorded on a straight-line basis.



F-10







Stock-Based Compensation



The Company periodically issues stock options
to officers, directors, employees, Scientific and Clinical Advisory Board members, non-employees and consultants for services rendered.
Such issuances vest and expire according to terms established at the issuance date.



Stock-based payments to officers, directors
and employees, including grants of employee stock options, are recognized in the financial statements based on their grant date
fair values. Stock option grants, which are generally time-vested, are measured at the grant date fair value and charged to operations
on a straight-line basis over the vesting period. The fair value of stock options is determined utilizing the Black-Scholes option-pricing
model, which is affected by several variables, including the risk-free interest rate, the expected dividend yield, the life of
the equity award, the exercise price of the stock option as compared to the fair value of the common stock on the grant date, and
the estimated volatility of the common stock over the term of the equity award.



Stock options granted to members of the Company’s
Scientific and Clinical Advisory Board, non-employees and outside consultants are revalued each reporting period to determine the
amount to be recorded as an expense in the respective period. As the stock options vest, they are valued on each vesting date and
an adjustment is recorded for the difference between the value already recorded and the value on the date of vesting.



The risk-free interest rate is based on the
U.S. Treasury yield curve in effect at the time of grant. Until the Company has established a trading market for its common stock,
estimated volatility is based on the average historical volatilities of comparable public companies in a similar industry. The
expected dividend yield is based on the current yield at the grant date; the Company has never declared or paid dividends and has
no plans to do so for the foreseeable future. As permitted by Staff Accounting Bulletin No. 107, due to the Company’s lack
of trading history and option activity, management utilizes the simplified method to estimate the expected term of options at the
date of grant. The fair value of common stock is determined by reference to either recent or anticipated cash transactions involving
the sale of the Company’s common stock. The Company accounts for forfeitures as they occur in accordance with ASU 2016-09,
Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU
2016-09”), and reverses previously recognized stock compensation costs in the period that the award is forfeited.



The Company recognizes the fair value of
stock-based compensation in general and administrative expenses and in research and development expenses in the Company’s
statement of operations, depending on the type of services provided by the recipient of the equity award. The Company issues new
shares of common stock to satisfy stock option exercises.



Income Taxes



The Company accounts for income taxes under
an asset and liability approach for financial accounting and reporting for income taxes. Accordingly, the Company recognizes deferred
tax assets and liabilities for the expected impact of differences between the financial statements and the tax basis of assets
and liabilities.



The Company accounts for uncertainties in
income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of
uncertain tax positions taken or expected to be taken in income tax returns as prescribed by GAAP. The tax effects of a position
are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date.
If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are
recognized.



The Company records a valuation allowance
to reduce its deferred tax assets to the amount that is more likely than not to be realized. In the event the Company was to determine
that it would be able to realize its deferred tax assets in the future in excess of its recorded amount, an adjustment to the deferred
tax assets would be credited to operations in the period such determination was made. Likewise, should the Company determine that
it would not be able to realize all or part of its deferred tax assets in the future, an adjustment to the deferred tax assets
would be charged to operations in the period such determination was made.



The Company is subject to U.S. Federal and
Massachusetts state income taxes. As the Company’s net operating losses have yet to be utilized, all previous tax years remain
open to examination by Federal and state taxing authorities in which the Company currently operates.



The Company recognizes interest accrued relative
to unrecognized tax benefits in interest expense and penalties in operating expense. During the years ended December 31, 2017,
2016 and 2015, the Company did not recognize any income tax related interest and penalties. The Company did not have any accruals
for income tax related interest and penalties at December 31, 2017 and 2016.



F-11







Comprehensive Income (Loss)



Components of comprehensive income or loss,
including net income or loss, are reported in the financial statements in the period in which they are recognized. Comprehensive
income or loss is defined as the change in equity during a period from transactions and other events and circumstances from non-owner
sources. Net income (loss) and other comprehensive income (loss) are reported net of any related tax effect to arrive at comprehensive
income (loss). The Company did not have any items of comprehensive income (loss) for the years ended December 31, 2017, 2016
and 2015.



Earnings (Loss) Per Share



The Company’s computation of earnings
(loss) per share (“EPS”) for the respective periods includes basic and diluted EPS. Basic EPS is measured as the income
(loss) attributable to common stockholders divided by the weighted average number of common shares outstanding for the period.
Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of potential common shares that would
result from the exercise of outstanding stock options and warrants as if they had been exercised at the beginning of the periods
presented, or issuance date, if later. Potential common shares that have an anti-dilutive effect (i.e., those that increase income
per share or decrease loss per share) are excluded from the calculation of diluted EPS. Basic and diluted loss per common share
is the same for all periods presented because all outstanding stock options and warrants are anti-dilutive.



At December 31, 2017, 2016 and 2015,
the Company excluded the outstanding securities summarized below, which entitle the holders thereof to acquire shares of common
stock, from its calculation of earnings per share, as their effect would have been anti-dilutive. The common stock to be issued
is not included in the calculation of earnings per share.



|                      |  | December 31, |          
|--------------------- |  | ------------ | ---------
|                      |  | 2017         |          
|Common stock warrants |  |              | 1,252,441
|Common stock options  |  |              | 2,732,221
|Total                 |  |              | 3,984,662



Fair Value of Financial Instruments



The authoritative guidance with respect to
fair value established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into
three levels, and requires that assets and liabilities carried at fair value be classified and disclosed in one of three categories,
as presented below.



Level 1.   Observable inputs
such as quoted prices in active markets for an identical asset or liability that the Company has the ability to access as of the
measurement date. Financial assets and liabilities utilizing Level 1 inputs include active-exchange traded securities and exchange-based
derivatives.



Level 2.   Inputs, other than
quoted prices included within Level 1, which are directly observable for the asset or liability or indirectly observable through
corroboration with observable market data. Financial assets and liabilities utilizing Level 2 inputs include fixed income securities,
non-exchange based derivatives, mutual funds, and fair-value hedges.



Level 3.   Unobservable inputs
in which there is little or no market data for the asset or liability which requires the reporting entity to develop its own assumptions.
Financial assets and liabilities utilizing Level 3 inputs include infrequently-traded non-exchange-based derivatives and commingled
investment funds, and are measured using present value pricing models.



The Company determines the level in the fair
value hierarchy within which each fair value measurement falls in its entirety, based on the lowest level input that is significant
to the fair value measurement in its entirety. In determining the appropriate levels, the Company performs an analysis of the assets
and liabilities at each reporting period end.



F-12







There were no financial instruments that
were measured and recorded at fair value on the Company’s balance sheet at December 31, 2017 and 2016.



The carrying value of financial instruments
(consisting of cash, a certificate of deposit, accounts payable, accrued compensation and accrued expenses) is considered to be
representative of their respective fair values due to the short-term nature of those instruments.



Recent Accounting Pronouncements



In May 2014, the Financial Accounting
Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU
2014-09”). ASU 2014-09 will eliminate transaction- and industry-specific revenue recognition guidance under current GAAP
and replace it with a principle based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize
revenue based on the value of transferred goods or services as they occur in the contract. ASU 2014-09 also will require additional
disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including
significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The FASB
has issued ASU 2016-08, ASU 2016-10, ASU 2016-11, ASU 2016-12, and ASU 2016-20, all of which clarify certain implementation guidance
within ASU 2014-09. ASU 2014-09 is effective for reporting periods beginning after December 15, 2017, with early adoption
permitted. Entities will be able to transition to the standard either retrospectively or as a cumulative-effect adjustment as of
the date of adoption. The Company will adopt the provisions of ASU 2014-09 in the quarter beginning January 1, 2018. As the
Company is unlikely to generate any sustainable operating revenues in the next several years, the adoption of ASU 2014-09 is not
currently expected to have any impact on the Company’s financial statement presentation or disclosures.



In November 2015, the FASB issued Accounting
Standards Update No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”).
ASU 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial
position. ASU 2015-17 is effective for financial statements issued for annual periods beginning after December 15, 2016, and
interim periods within those annual periods. The Company adopted the provisions of ASU 2015-17 in the quarter beginning January 1,
2017. The adoption of ASU 2015-17 did not have any impact on Company’s financial statement presentation or disclosures.



In February 2016, the FASB issued Accounting
Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 requires a lessee to record a right-of-use
asset and a corresponding lease liability, initially measured at the present value of the lease payments, on the balance sheet
for all leases with terms longer than 12 months, as well as the disclosure of key information about leasing arrangements. ASU 2016-02
requires recognition in the statement of operations of a single lease cost, calculated so that the cost of the lease is allocated
over the lease term, generally on a straight-line basis. ASU 2016-02 requires classification of all cash payments within operating
activities in the statement of cash flows. Disclosures are required to provide the amount, timing and uncertainty of cash flows
arising from leases. A modified retrospective transition approach is required for lessees for capital and operating leases existing
at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain
practical expedients available. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim
periods within those fiscal years. Early application is permitted. The Company will adopt the provisions of ASU 2016-02 in the
quarter beginning January 1, 2019. The Company generally does not finance purchases of property and equipment, but does lease
its operating facilities. While the Company is continuing to assess the potential impact of ASU 2016-02, it currently expects that
most of its lease commitments will be subject to ASU 2016-02 and accordingly, upon adoption will be recognized as lease liabilities
and right-of-use assets in the Company’s balance sheet.



In March 2016, the FASB issued Accounting
Standards Update No. 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based
Payment Accounting (“ASU 2016-09”). ASU 2016-09 requires, among other things, that all income tax effects of awards
be recognized in the statement of operations when the awards vest or are settled. ASU 2016-09 also allows for an employer to repurchase
more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and allows
for a policy election to account for forfeitures as they occur. ASU 2016-09 is effective for fiscal years beginning after December 15,
2016, including interim periods within those fiscal years. The Company adopted the provisions of ASU 2016-09 in the quarter beginning
January 1, 2017. The adoption of ASU 2016-09 did not have any impact on the Company’s financial statement presentation
or disclosures.



F-13









In July 2017, the FASB issued Accounting
Standards Update No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and
Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features; (Part II) Replacement of the
Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable
Noncontrolling Interests with a Scope Exception (“ASU 2017-11”). ASU 2017-11 allows companies to exclude a down round
feature when determining whether a financial instrument (or embedded conversion feature) is considered indexed to the entity’s
own stock. As a result, financial instruments (or embedded conversion features) with down round features may no longer be required
to be accounted for as derivative liabilities. A company will recognize the value of a down round feature only when it is triggered
and the strike price has been adjusted downward. For equity-classified freestanding financial instruments, an entity will treat
the value of the effect of the down round as a dividend and a reduction of income available to common shareholders in computing
basic earnings per share. For convertible instruments with embedded conversion features containing down round provisions, entities
will recognize the value of the down round as a beneficial conversion discount to be amortized to earnings. ASU 2017-11 is effective
for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted.
The guidance in ASU 2017-11 can be applied using a full or modified retrospective approach. The adoption of ASU 2017-11 is not
currently expected to have any impact on the Company’s financial statement presentation or disclosures.



Management does not believe that any other
recently issued, but not yet effective, authoritative guidance, if currently adopted, would have a material impact on the Company’s
financial statement presentation or disclosures.

| | 5. | Einstein License and Service Agreement
| | -- | --------------------------------------



License Agreement



On January 14, 2015, the Company entered
into a license agreement, as amended on June 2, 2015 (the “Einstein License”), with Einstein for certain patent
rights (the “Patents”) relating to the Company’s core technology platform for the engineering of biologics to
control T-cell activity, precision, immune-modulatory drug candidates, and two supporting technologies that enable the discovery
of costimulatory signaling molecules (ligands) and T-cell targeting peptides. On July 31, 2017, the Company entered into an
amended and restated license agreement which modified certain obligations of the parties under the Einstein License.



F-14







Under the Einstein License, the Company holds
an exclusive worldwide license, with the right to sublicense, import, make, have made, use, provide, offer to sell, and sell all
products, processes and services that use the Patents, including certain technology received from Einstein relating thereto (the
“Licensed Products”). Under the Einstein License, the Company is required to:



| | · | Pay royalties based on certain percentage of proceeds, as defined in the Einstein License, from sales of Licensed Products,
including sublicense agreements.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Pay escalating annual maintenance fees as follows: $25,000 on January 14, 2017; $50,000 on each of January 14, 2018
and 2019; $75,000 on each of January 14, 2020 and 2021; and $100,000 on January 14, 2022 and each year thereafter. Annual
maintenance fees are nonrefundable, but are creditable against the amount due to Einstein for royalties during the 12 month period
following each of the due dates for annual maintenance fees.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Make significant payments up to $5,000,000 based upon the achievement of certain milestones, as defined in the Einstein License.
Payments made upon achievement of milestones are nonrefundable and are not creditable against any other payment due to Einstein.
At December 31, 2017, none of these milestones had been achieved by the Company.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Incur a minimum of $250,000 per year of product development costs until the first commercial sale of the first licensed
product.
| | - | --------------------------------------------------------------------------------------------------------------------------------



The Company was in compliance with its obligations
under the Einstein License at December 31, 2017 and 2016.



The Einstein License expires upon the expiration
of the Company’s last obligation to make royalty payments to Einstein which may be due with respect to certain Licensed Products,
unless terminated earlier under the provisions thereof. The Einstein License includes certain termination provisions if the Company
fails to meet its obligations thereunder.



The Einstein License required the Company
to issue to Einstein a specified number of shares of common stock of the Company on a fully diluted, as converted basis, depending
on the achievement of (1) a funding threshold and (2) a liquidity event, each as defined in the Einstein License. The funding
threshold was achieved through the completion of the June 15, 2015 private placement as described in Note 8. A liquidity event
includes, but is not limited to, an initial public offering of shares of the Company’s common stock; a merger with a public
reporting company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or a company whose shares
are listed on a non-U.S. exchange or an affiliate thereof; a merger, consolidation, reorganization, or similar transaction whereby
the Company’s stockholders immediately prior to the consummation of the transaction will own less than the majority of the
voting power of the resulting corporation after the consummation of the transaction; or a sale of substantially all of the Company’s
assets. Accordingly, the Company was required to issue 671,572 shares of the Company’s common stock to Einstein immediately
prior to the consummation of an initial public offering by the Company on December 27, 2017. The common stock issued to Einstein
upon the occurrence of a liquidity event has certain registration rights, as described in Note 11.



The Company accounted for the issuance
of these shares as a charge to research and development expenses in the statement of operations at their aggregate fair value
of $5,036,789 on the date of issuance, in accordance with ASC 730, Research and Development, as the Patents acquired from
Einstein are for use in the Company’s research and development activities exclusively with respect to its core
technology platform and have no alternative future use by the Company, and therefore no separate economic value. The shares
issuable in connection with Einstein License were recorded as common stock to be issued at December 31, 2017, and were issued
on January 9, 2018.



The Company accounts for the costs incurred
in connection with the Einstein License in accordance with ASC 730, Research and Development. For the years ended December 31,
2017, 2016, and 2015, costs incurred with respect to the Einstein License aggregated $5,084,708, $31,250, and $127,336, respectively,
and are included in research and development expenses in the statements of operations.



Service Agreement



On October 1, 2015, the Company entered
into a service agreement (the “Service Agreement”) with Einstein to support the Company’s ongoing research and
development activities. The initial term of the Service Agreement was for three months, which was amended in February 2016
to extend it for the period of time deemed necessary to complete the services pursuant to the terms of the Service Agreement. For
the years ended December 31, 2017, 2016, and 2015, costs incurred with respect to the Service Agreement aggregated $0, $80,000,
and $200,000, respectively, and are included in research and development expenses in the statement of operations.

| | 6. | Acquisition of Trademark
| | -- | ------------------------



On May 4, 2017, the Company entered
into a settlement agreement with Cue BioLogics, LLC, an unrelated party, to acquire all right, title and interest in and to the
CUE BIOLOGICS mark, and any derivative mark incorporating CUE, throughout the world, together with all associated goodwill and
common law rights appurtenant thereto, including, but not limited to, any right, title and interest in any corporate name, company
name, business name, trade name, dba, domain name, or other source identifier incorporating CUE (collectively, the “CUE BIOLOGICS
Mark”), in exchange for a cash payment by the Company of  $175,000.



Accounting Standards Codification (“ASC”)
350-30-20 defines a defensive intangible asset as an acquired intangible asset in a situation in which an entity does not intend
to actively use the asset but intends to hold (lock up) the asset to prevent others from obtaining access to the asset. The Company
determined that the acquired intangible asset met the definition of a defensive intangible asset and has therefore accounted for
the $175,000 payment to Cue BioLogics, LLC for the CUE BIOLOGICS Mark as an acquired intangible asset.



| | 7. | Stock-Based Compensation
| | -- | ------------------------



Effective March 23, 2016, the Company
adopted the 2016 Omnibus Incentive Plan (the “Omnibus Plan”) and the 2016 Non-Employee Equity Incentive Plan (the “Non-Employee
Plan”), which are intended to allow the Company to compensate and retain the services of key employees, non-employees, Scientific
and Clinical Advisory Board members, and outside advisors and consultants. The plans are under the administration of the Company’s
Board of Directors. Under the plans, the Company, at its discretion, may grant stock option awards to certain employees and non-employees
through March 23, 2026. The Omnibus Plan and the Non-Employee Plan provide for the grant of a total of 2,000,000 shares and
500,000 shares of common stock, respectively.



On August 13, 2017, the Company’s Board
of Directors approved an amendment and restatement of the Company’s 2016 Omnibus Incentive Plan to increase the number of
shares authorized for issuance under such plan by 800,000 shares, from 2,000,000 shares to 2,800,000 shares, subject to stockholder
approval of such amendment within 12 months following board approval thereof. The Company’s stockholders approved the plan
in December 2017. The 2016 Omnibus Incentive Plan, as amended and restated, provides that on the first day of each fiscal year
of the Company during the period beginning in fiscal year 2018 and ending on the second day of fiscal year 2027, the number of
shares of common stock authorized to be issued under such plan shall be increased by an amount equal to the lesser of  
(i) the number of shares necessary such that the aggregate number of shares available to be issued under the plan equals 20% of
the number of fully diluted outstanding shares on such date (assuming the conversion of all outstanding shares of preferred stock
and other outstanding convertible securities and exercise of all outstanding options and warrants to purchase shares) and (ii)
an amount to be determined by the Company’s Board of Directors.



Pursuant to the plans, during the year ended
December 31, 2017, the Company granted stock options to purchase 1,089,000 shares of the Company’s common stock, of
which 150,000 were granted to members of the Scientific and Clinical Advisory Board, 60,000 to independent members of the Company’s
Board of Directors, 100,000 to independent consultants, 385,000 to members of management, and 394,000 to other employees. The stock
options granted to independent members of the Board of Directors, members of the Scientific and Clinical Advisory Board, and independent
consultants were non-qualified stock options, whereas all other stock options were incentive stock options. At December 31,
2017, stock options for 2,362,221 shares of common stock had been granted and 437,779 shares of common stock were reserved for
future grants under the Omnibus Plan, and stock options for 370,000 shares of common stock had been granted and 130,000 shares
of common stock were reserved for future grants under the Non-Employee Plan. In the aggregate, at December 31, 2017, stock
options for a total of 2,732,221 shares of common stock had been granted and 567,779 shares of common stock were reserved for future
grants. Such grants are accounted for as share-based compensation in accordance with ASC 718, Compensation - Stock Compensation,
and ASC 505-50, Equity-Based Payments to Non-Employees.



For stock options requiring an assessment
of value during the years ended December 31, 2017 and 2016, the fair value of each stock option award was estimated using
the Black-Scholes option-pricing model utilizing the following assumptions:



F-16







|                        |  | December 31, |               
|----------------------- |  | ------------ | --------------
|                        |  | 2017         |               
|Risk-free interest rate |  | 1.71 to 2.22 | %             
|Expected dividend yield |  |              | 0             
|Expected volatility     |  |              | 80.9-83.0     
|Expected life           |  |              | 3.2 to 7 years



The risk-free interest rate is based on the
U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected term of the stock option award;
as permitted by Staff Accounting Bulletin 107, due to insufficient history of stock option activity, management has utilized the
simplified approach to estimate the expected term of the stock options, which represents the period of time that stock options
granted are expected to be outstanding; the expected volatility is based upon historical volatilities of comparable companies in
a similar industry; and the expected dividend yield based upon the Company’s current dividend rate and future expectations.



A summary of stock option activity for the
years ended December 31, 2017 is as follows:

In assessing the potential realization of
deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets
will be realized. The ultimate realization of deferred tax assets is dependent upon the Company attaining future taxable income
during the periods in which those temporary differences become deductible. As of December 31, 2017 and 2016, management was
unable to determine if it is more likely than not that the Company’s deferred tax assets will be realized, and has therefore
recorded a 100% valuation allowance against deferred tax assets at such dates.



No Federal tax provision has been provided
for the years ended December 31, 2017, 2016, and 2015 due to the losses incurred during such periods. A reconciliation of the difference
between the income tax rate computed by applying the U.S. Federal statutory rate and the effective tax rate for the years ended
December 31, 2017, 2016 and 2015 is as follows:

The Company has applied the provisions of
ASC 740, Income Taxes, which clarifies the accounting for uncertainty in tax positions and requires the recognition of the impact
of a tax position in the financial statements if that position is more likely than not of being sustained on a tax return, based
on the technical merits of the position, upon examination by the relevant taxing authority. At December 31, 2017 and 2016,
the Company had unrecognized tax benefits related to Federal and state research tax credits of approximately $510,000 and $157,000,
respectively. The Company is subject to Federal and state income tax examinations by tax authorities for all years since its incorporation
in 2014. The Company is currently not under examination by any tax authority.



At December 31, 2017, the Company
has available net operating loss carryforwards for Federal and state income tax purposes of approximately $28,700,000 and
$29,100,000, respectively, which, if not utilized earlier, will begin to expire in 2035. The Company has Federal research
credits of approximately $944,000, which, if not utilized earlier, will begin to expire in 2035, and state research credits
of approximately $433,000, which, if not utilized earlier, will begin to expire in 2031. At December 31, 2017 the Company
recorded $250,000 in research credits as prepaid to be offset against payroll tax liabilities associated with research and
development personnel in 2018.



On December 22, 2017, the Tax Cuts
and Jobs Acts was enacted into law.  The new tax legislation represents a fundamental and dramatic shift in US
taxation.  The new legislation contains several key tax provisions that will impact the Company including the reduction
of the corporate income tax rate to 21% effective January 1, 2018. ASC 740 requires the Company to recognize the effect of
the tax law change in the period of enactment. The lower tax rate requires the Company to remeasure  its deferred tax assets
and liabilities in fourth quarter of 2017. The total amount of the Company’s deferred tax assets before valuation allowance decreased
by $4.3 million as a result of the decrease in the federal tax rate.



ASC 740 requires the Company
to recognize the effect of the tax law changes in the period of enactment. The lower corporate income tax rate will require
the Company to remeasure  its US deferred tax assets and liabilities as well as reassess the realizability of  its deferred
tax assets and liabilities.  The SEC staff has issued SAB 118 which will allow  the Company to record provisional
amounts during a measurement period which is similar to the measurement period used when accounting for business
combinations.  The Company will continue to assess the impact of the recently enacted tax law on its business and financial statements and will reflect the provisional impact of the tax law change in the fourth quarter of
fiscal 2017.

The Company’s commitments with respect
to the Einstein License and the Service Agreement are summarized in Note 5.



Leased Facilities



On July 29, 2015, the Company entered
into an operating lease agreement for its laboratory space for the period from August 1, 2015 through April 30, 2018.
The lease contains escalating payments during the lease period. The Company records monthly rent expense on the straight-line basis,
equal to the total of the lease payments over the lease term divided by the number of months of the lease term.



On November 14, 2016, the Company entered
into an amended lease agreement that provided the Company with additional laboratory space. This amendment was effective beginning
December 1, 2016 and continues through the expiration of the lease on April 30, 2018.



F-21







On July 30, 2015, the Company entered
into an operating lease agreement, as amended, for dedicated vivarium space for the period from August 1, 2015 through March 31,
2018. The operating lease agreement contains an option to increase the amount of space leased for an additional cost.



Future minimum lease payments under these
leases at December 31, 2017 are as follows:



|Years Ending December 31, |  |   |          
|------------------------- |  | - | ---------
|2018                      |  | $ | 1,004,000

|Total                      |  | $                        | 1,975,589



Legal Contingencies



The Company may be subject to various legal
proceedings from time to time as part of its business. As of December 31, 2017, the Company was not a party to any legal proceedings
or threatened legal proceedings, the adverse outcome of which, individually or in the aggregate, would have a material adverse
effect on its business, financial condition or results of operations.



Registration Statement Filing Obligations



In conjunction with the sale of common stock
on June 15, 2015 and on December 22, 2016 (see Note 8), including placement agent warrants issued to MDB, the Company
granted the investors and MDB certain piggy-back registration rights commencing 180 days after the date that the Company becomes
a reporting company under the Exchange Act, and for a period of five years thereafter, and a one-time demand registration right
commencing 180 days after the date that the Company becomes a reporting company under the Exchange Act. These registration rights
terminate for a holder upon the earliest of when all underlying securities held by the holder (i) have been sold pursuant to a
registration statement, (ii) have been covered by an effective registration statement which has been effective for an aggregate
period of 16 months, or (iii) may be sold by the holder pursuant to Rule 144 of the Securities Act of 1933, as amended, without
regard to both the volume limitations for sales as provided in Rule 144 and the limitations for such sales provided in Rule 144(i).



In conjunction with the sale of common stock
on December 22, 2016 (see Note 8), the Company granted the investors certain piggy-back and demand registration rights with
respect to the common stock commencing six months after an initial public offering by the Company, by joinder to the registration
rights agreement entered into by the Company and investors in connection with the Company’s June 15, 2015 private placement
of common stock.



In conjunction with the Company’s initial
public offering of common stock in December, 2017 (see Note 8), the Company issued warrants to the underwriter, MDB, to purchase
shares of common stock. These warrants include certain piggy-back and demand registration rights with respect to the common stock
issuable upon exercise thereof. These registration rights terminate for a holder upon the earliest of when all underlying securities
held by the holder (i) have been sold pursuant to a registration statement, (ii) have been covered by an effective registration
statement which may be kept effective as an evergreen registration statement, or (iii) may be sold by the holder within a 90 day
period without registration pursuant to Rule 144 of the Securities Act of 1933, as amended, or consistent with applicable SEC interpretive
guidance.



Upon the completion of an initial public
offering, the Company is required to use its best efforts to file a registration statement covering the resale of the shares of
common stock issued to Einstein (see Note 5) as soon as practicable, but no later than 180 calendar days from the date of the initial
public offering, and to cause such registration statement to be declared effective by the United States Securities and Exchange
Commission within 120 calendar days from the date of issuance of the shares.



F-22







Agreement with MDB



Effective April 13, 2015, the Company
entered into an agreement with MDB to engage such firm as its exclusive placement agent in connection with one or more offerings
of the Company’s securities. As consideration for the services to be provided under the agreement, MDB was entitled to a
cash fee equal to 10% of the gross proceeds raised in a financing, and warrants for up to 10% of the aggregate securities sold
in an offering, exercisable for seven years at 100% of the offering price per share in a private offering and at not less than
120% of the offering price per share in a public offering, each for a cash consideration of $1,000. The agreement provided for
the reimbursement of legal expenses incurred by MDB in conjunction with a securities offering.



Effective December 22, 2016, the Company
amended the agreement with MDB to modify the consideration that MDB is entitled to receive for its placement agent services, to
provide for a cash fee equal to 10% of the initial $10,000,000 of gross proceeds raised in a financing and 5% of the amount in
excess of $10,000,000 in gross proceeds raised in a financing, and that MDB shall receive no placement agent warrants.



Agreements with Catalent



Catalent is a global provider of drug delivery
technology and development solutions for drugs, biologics and consumer health products.



On March 7, 2017, the Company entered
into an agreement with Catalent for Catalent to provide services on a sequential milestone basis with respect to the development
and manufacture of the Company’s lead drug candidate, CUE-101. The services under the agreement are designed to support the
preparation and filing of an Investigational New Drug Application with the United States Food and Drug Administration to allow
for the commencement of a Phase 1 clinical trial of CUE-101 in the United States. The Company currently estimates that it will
incur total direct costs under this agreement aggregating approximately $5,875,000, most of which the Company estimates to be
incurred during the years ending December 31, 2017 and 2018. The company incurred total direct cost under this agreement aggregating
$2.4 million during the year ended December 31, 2017, of which approximately $1.6 million was expensed during the year ended December 31, 2017. The remaining
$0.8 million are reflected as research and development advances for which the Company anticipates receiving the contracted services within 12 months from the date of payment.
Management periodically reviews and updates the project’s estimated budget and timeline.



On July 5, 2017, the Company entered
into a separate Master Services Agreement with Catalent that outlines the terms and conditions under which Catalent will provide
contract services with respect to the Company’s research and development activities for a period of five years. The Company
may terminate this agreement without cause upon 90 days prior written notice. Unless and until terminated, this agreement will
automatically be extended for successive one-year periods.



Collaboration Agreement with Merck



On November 14, 2017, the Company entered into an Exclusive
Patent License and Research Collaboration Agreement (the “Collaboration Agreement”) with Merck for a partnership to
research and develop certain of the Company’s proprietary biologics that target certain autoimmune disease indications (the
“Initial Indications”). The Company views this Collaboration Agreement as a component of its development strategy since
it will allow the Company to advance its autoimmune programs in partnership with a world class pharmaceutical company. The research
program outlined in the Collaboration Agreement entails (1) research, discovery and development of certain CUE BiologicsTM
drug candidates up to the point of demonstration of certain biologically relevant effects (“Proof of Mechanism”) and
(2) the further development by Merck of the CUE BiologicsTM drug candidates that have demonstrated Proof of Mechanism (the
“Proposed Product Candidates”) up to the point of demonstration of all or substantially all of the properties outlined
in such Proposed Product Candidates’ profiles as described in the Collaboration Agreement.



F-23







For the purposes of this collaboration, the Company has granted
to Merck under the Collaboration Agreement an exclusive license under certain of its patent rights, including a sublicense of patent
rights licensed from Einstein, to the extent applicable to the specific CUE BiologicsTM that are elected to be developed by
Merck. From the effective date of the Collaboration Agreement until the earlier of  (i) the first achievement of Proof of
Mechanism for a CUE BiologicsTM drug candidate or (ii) 18 months after we notify the joint steering committee that the first
Product Candidate has been synthesized under the research program, the Company is required to forebear from researching, developing
or licensing to a third party rights related to any CUE BiologicsTM drug candidate for the treatment of autoimmune diseases
other than pursuant to the Collaboration Agreement. In addition, so long as Merck continues product development on a Proposed Product
Candidate, the Company is restricted from conducting any development activities within the Initial Indication covered by such Proposed
Product Candidate other than pursuant to the Collaboration Agreement. The Company is not required to forbear at any time, however,
from developing other CUE BiologicsTM for use in therapeutic areas other than autoimmune diseases, e.g., for use in treating
cancer or infectious diseases.



In exchange for the licenses and other
rights granted to Merck under the Collaboration Agreement, Merck paid the Company a $2.5 million nonrefundable up-front
payment which was recorded as a deferred credit in the accompanying balance sheet at December 31, 2017. As related research
and development costs are incurred, the applicable amount of deferred credit will be recorded as an offset to research
and development costs in the statement of operations. The Company may be eligible to receive funding in developmental
milestone payments, as well as tiered royalties, if all research, development, regulatory and commercial milestones agreed
upon by both parties are successfully achieved.



| | 12. | Cue Biopharma 401(k) Plan
| | --- | -------------------------



Effective as of January 1, 2017, the
Company adopted the Cue Biopharma 401(k) Plan (the “Plan”) for all employees of the Company. Employees may participate
in the Plan upon complying with the Plan’s eligibility requirements, subject to limitations imposed by the Internal Revenue
Service. Under the Plan, the Company may match employee contributions at its discretion. The Company did not make any contributions
to the Plan during the year ended December 31, 2017.



| | 13. | Subsequent Events
| | --- | -----------------



On January 16, 2018, the Company entered
into an amended lease agreement that provided the Company with additional laboratory space. This amendment was effective beginning
on January 16, 2018 and continues through the expiration of the lease on April 30, 2018.



On January 18, 2018, the Company entered
into an operating lease agreement for its laboratory and office space at 21 Erie St. Cambridge, Massachusetts for the period from
May 1, 2018 through April 30, 2021.The lease contains escalating payments during the lease period.



Future minimum lease payments under this
lease are as follows:



|Years Ending December 31, |  |   |           
|------------------------- |  | - | ----------
|2018                      |  | $ | 2,380,000

Item 9. Changes in and Disagreements with Accountants on
Accounting and Financial Disclosure.



None.



Item 9A. Controls and Procedures.



Evaluation of Disclosure Controls and Procedures



As of the end of the period covered by this report, management
performed, with the participation of our principal executive and principal financial officers, an evaluation of the effectiveness
of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Our disclosure controls
and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange
Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s forms, and that such
information is accumulated and communicated to our management, including our principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosures. Based on the evaluation, our principal executive and principal
financial officers concluded that, as of December 31, 2017, our disclosure controls and procedures were effective.



Management’s Report on Internal Control Over
Financial Reporting



This Annual Report on Form 10-K does not include a report of
management’s assessment regarding internal control over financial reporting or an attestation report of the Company’s registered
public accounting firm due to a transition period established by rules of the SEC for newly public companies.



Changes in Internal Control Over Financial Reporting



As previously reported in the registration statement on Form
S-1 for our initial public offering, in connection with the audit of our financial statements for the year ended December 31,
2016 we identified a material weakness in our internal control over financial reporting. The material weakness related to a lack
of effective controls to adequately restrict access and segregation of duties, specifically due to the limited number of staff
in our accounting function. During the quarter ended December 31, 2017 we hired additional finance resources and in connection
with our review of disclosure controls and procedures as of December 31, 2017 we concluded this material weakness had been remediated.
Other than as described in the preceding sentence, for the quarter ended December 31, 2017, there were no changes in our internal
control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control
over financial reporting.
