A Letter from David L. Lucchino
Chief Executive Officer

Dear fellow shareholders,

At Frequency, our mission has never been clearer: to develop and 
commercialize the first medicine to restore hearing. We aim to 
transform treatment of the most common form of hearing loss for 
millions of patients around the globe. 

We are proud to be leaders in a field where there is now significant 
new focus and investment in potential restorative treatments 
for sensorineural hearing loss. Our hope is that from this focus 
will emerge an array of new therapeutic options for patients and 
providers that will lead to better hearing care and hearing health. 

The renaissance in the field of hearing therapeutics has been 
driven by several factors: 

• First, a recognition that the science has advanced to a point 
where treatment may move beyond simply addressing the 
symptoms of hearing loss, instead repairing the underlying 
causes of the disease.

• Second, the scientific and medical communities possess a   
fuller understanding that the current standard of care is 
insufficient, and there is a profound need to address speech 
clarity in addition to audibility. 

• Third, there is increasing evidence that hearing loss may be 
associated with the risk of other serious diseases and ailments, 
including dementia. 

We believe we have several advantages that provide us with 
the opportunity for sustained long-term leadership in cochlear 
regeneration: the strength of our world-class team and the breadth 
of our expertise across hearing research, audiology and clinical 
development; our deep regenerative biology knowledge, small 
molecule approach and advanced drug delivery that uses well-
understood administration; and the bounty of clinical data across 
patient populations and hearing loss causes and severities that will 
enable us to continuously refine the target group of subjects that 
may benefit from our treatment.

We now have two independent, single-dose studies from our 
lead therapeutic candidate, FX-322. Both show a hearing signal 
and statistically significant improvements in speech intelligibility 
in patients with sensorineural hearing loss. The data from these 
studies provides us with confidence in FX-322 and its potential as a 
novel treatment option, one that initially may have the potential to 
treat 10 – 15 million individuals in the U.S. alone. 

3

 
 
As a company, we plan to expand into new 
areas where we can use our expertise in  
inner-ear biology to pursue additional 
treatment areas, optimizing our work in 
progenitor cell activation (PCA) and beyond. 

And we have a lot on which to build. At the time 
of this writing, we had just reported preliminary 
data from our Phase 2a study of patients with 
noise-induced and sudden sensorineural 
hearing loss, as well as new data from a Phase 
1b safety study where we continued to observe 

the hearing signal from our Phase 1/2 study. 

While the Phase 2a study did not provide us 
the outcome we had hoped for, we learned 
an incredible amount about dosing and entry 
criteria to apply to future studies. We believe 
we have a clear path forward and intend to 
pursue single administrations of FX-322 in these 
future studies. In a field without an approved 
drug to treat hearing loss, we expect to learn a 
great deal more from upcoming trials to further 
guide us in bringing a treatment to patients.

A Classical Musician Faces the Music

Sensorineural hearing loss 
caused classical musician 
Betty H. to give up on 
performing, but she has still 
found a second act in music.

Performing took Betty from 
the White House to the Middle 
East, and for fifty years she 
shared stages with the likes 
of Yo-Yo Ma. After struggling 
with tinnitus (ringing in the 
ears) and overall hearing, 
Betty sought professional 
help and began using 
hearing aids in rehearsals to 
understand people’s voices, 
though she opted not to wear 
them during performances. 
Eventually she realized she’d 
need to wear them on stage, 

too. In her mid 60s, she was 
performing a Bach cantata 
at the Emmanuel Church in 
Boston, when she decided to 
quit. It was in the middle of 
a quiet section in the piece, 
when the ensemble needed 
to follow the vocal cues of 
a singer. She couldn’t keep 
up and decided she couldn’t 
perform in public anymore. 

Betty now tours in a different 
way — speaking to groups to 
raise awareness of hearing loss 
and to connect with people 
with similar struggles. She also 
performs on viola and violin, 
helping folks reconnect with 
music in simple, quiet settings.

The World Health 
Organization 
projects that by 
2050, nearly 1 in 4 
people globally will 
have some form of 
hearing loss.

Reimagining hearing loss treatments means 
developing therapies designed to repair 
the inner workings of the cochlea, replacing 
missing cells, and reconnecting the neuronal 
connections both to hear and to tune and 
filter sound. While the audibility (volume) of 
sound is important, our ability to understand 
and interpret sound and speech is essential for 
communication and connection.

Over the next several decades, the number 
of individuals with hearing loss in the U.S. is 
expected to nearly double. The World Health 
Organization projects that by 2050, nearly 1 in 4 
people globally will have some form of hearing 
loss. On its own, and given the association 
between hearing loss and the risk of other 
diseases such as dementia and depression, it 
is clear that hearing health is a growing public 
health concern. 

A medicine to restore hearing could provide 
a new path for individuals eager to address 
the root cause of their hearing loss. Our aim 
is to expand the universe of care by providing 
physicians with a new treatment option while 
creating new opportunities for audiologists to 
expand their practices and address a leading 
complaint of those suffering from SNHL: an 
inability to hear clearly.

In all, SNHL impacts more than 40 million 
people in the U.S. alone, the vast majority of 
whom are not being treated. This includes 
those with age-related, noise-induced, and 
sudden hearing loss, as well as hearing loss 
caused by toxic medications.

An Army Veteran Combats Hearing 
Loss at Frequency

Sam W. acquired hearing 
loss when he was an armor 
officer in the U.S. Army. He 
served for more than ten 
years, with tours in Kuwait 
and Iraq. Spending most days 
riding around in tanks, he was 
exposed to loud noises over 
sustained periods of time. 
Once he left the service, he 
was diagnosed with high-
frequency hearing loss.

Today, Sam struggles with 
many hearing challenges. He 
has difficulty hearing speech 
clearly and is at times unable 
to follow conversations with 
friends, family, and coworkers. 
He sometimes finds himself 
isolating from others, 
given that his hearing loss 

impacts his ability to interact 
effectively. According to the 
CDC, noise-induced hearing 
loss and tinnitus are the two 
leading medical conditions 
among veterans — outpacing 
other physical injuries.

Since leaving the Army, Sam 
became a statistician and has 
built a career in biotech. Today, 
as Director of Biostatistics 
at Frequency Therapeutics, 
he plays a critical role in 
Frequency’s hearing loss 
program. In this role, Sam 
hopes to one day give back to 
his fellow military colleagues 
who, like him, suffer from 
noise-induced hearing loss.

Brick by Brick

None of our advances this past year would 
have been possible without the remarkable 
work and resilience of our team and their 
ability to rapidly adapt to the challenges of the 
pandemic, while maintaining momentum for 
our clinical program. As thousands of studies 
were halted, we were fortunate to be working 
with private ENT (ear, nose, and throat) clinics, 
where the physicians at these sites around the 
U.S. demonstrated a steadfast commitment to 
the safety and welfare of their patients.

With their partnership, we were able to fully 
enroll our Phase 2a study — and even to 
start new studies. We are grateful for the 
commitment of these ENTs and their staff to 
their patients and to helping advance the field.

When we first shared our clinical data in 
2019, people frequently asked whether the 
improvements observed in patients’ hearing 
were due to the regrowth of sensory hair 
cells. Preclinical data suggested that this is 
the case, but directly visualizing drug effects 
in humans is much more difficult. Because 
hair cells grow within the cochlea, an organ in 
the inner ear which rests behind the hardest 
bone in the body, getting a clear picture of 
the pathophysiology or the regeneration of 
these cells is not possible by imaging. So, we 
pursued a brick-by-brick approach to more 
fully understand whether FX-322 was reaching 
its intended target and creating an associated 
drug response in human subjects.

8

To do so, we ran a study in Hannover, Germany, 
at one of the world’s busiest cochlear implant 
clinics, where researchers regularly evaluate 
fluid within the cochlea to identify genetic 
anomalies. Our focus was to understand 
whether FX-322 drug levels could be directly 
measured in this fluid, or perilymph, once 
injected in patients, something that otherwise 
would not be feasible because of the challenge 
of accessing the cochlea. Led by the clinic’s 
director, Prof. Thomas Lenarz, seven patients 
were injected with FX-322 prior to undergoing 
cochlear implant surgery. Study results showed 
measurable concentrations of FX-322 in every 
sample analyzed and at levels predicted to 
reach the therapeutically active concentration.

At that point, based on our observations, we 
saw that FX-322 had a favorable safety profile, 
had elicited a hearing signal in patients, and 
had reached the site of action in the cochlea. 
But we also wanted to understand whether 
the hearing signal we had seen in patients was 
durable. To understand this, Susan King, M.D., 
FACS, the lead investigator for the Phase 1/2 
study, brought responders back to her clinic for 
follow-up exams. 

Results were highly encouraging, as some 
patients who had shown clinically meaningful 
improvements in the earlier study maintained 
those improvements 13 – 21 months after 
receiving a single dose of FX-322. For some, 
this included sustained improvements both 
in speech intelligibility and audibility. (We 
also reported that one patient that initially 
responded had returned to baseline.) Last July, 
Dr. King shared these data in a keynote address 
at the American Academy of Otolaryngology 
– Head and Neck Surgery (AAO-HNS) Annual 
Meeting.

Seeking Real-World Improvements

In her San Antonio clinic, Dr. 
Susan King, a neurotologist 
and surgeon, sees a broad 
array of patients. She has 
dedicated her career to 
better hearing health. And 
the message the majority of 
patients share with her is a 
desire for treatments that not 
just improve their ability to 
hear, but also improve their 
ability to understand words 
and interpret sounds.

“In many cases these patients 
are desperate for new options 
and to see the existing 
standard of care expand to 
include new approaches.”

Dr. King has been a lead 
investigator on several of 
Frequency’s clinical studies, 
and she is inspired by 
patients who, regardless 
of outcomes, continue to 
encourage those in research 
and development to advance 
their work and push the 
boundaries of science: “This 
is a noisy world, which makes 
it particularly tough for those 
with hearing loss. Anything to 
help restore hearing could be 
transformative for quality of 
life and the ability to interact 
and engage with the world in 
ways they once knew.”

Both the Phase 1/2 and cochlear delivery study results 
were published in the peer-reviewed journal Otology & 
Neurotology in February 2021. They were also presented 
at the 2021 Association for Research in Otolaryngology 
44th Annual Mid-Winter Meeting that same month. 

Data from all of these studies bolstered our 
understanding of FX-322, allowing us to make important 
strategic decisions, including taking an early look at our 
Phase 2a study so we might begin to evaluate data at 
the group level. This approach gave us a head start — 
both in our planning for future studies and in expanding 
our understanding of additional patient populations 
FX-322 may support. In late 2020, we also commenced 
a Phase 1b study of FX-322 in patients with age-related 
hearing loss (ages 66–85) and a second in patients with 
severe hearing loss. These studies are expected to read 
out in Q2 and Q3 2021 respectively.

I believe our strategy and methodical approach to FX-322 development has been both thoughtful 
and innovative, allowing us to define the patient populations FX-322 may help and the breadth of 
the commercial opportunity ahead.

Preparing for 
Growth

This past year, we began to build out the 
foundation for our future growth. This included 
the hiring of key roles including our new chief 
financial officer, chief manufacturing officer, 
as well as our first commercial hire to lead 
strategic marketing and new product planning. 
We were excited to attract tremendous talent 
to these roles, including a respected thought 
leader with the addition of the former head of 
audiology from Mass Eye and Ear and Harvard 
Medical School. We expanded our hearing and 
multiple sclerosis research and development 
teams, and our bench in medicinal chemistry, 
CMC, and regulatory affairs. We also were able 
to raise an additional $42 million in 2020 from 
a syndicate of world-class life science investors, 
which enables us to put an even greater 
emphasis on research and future learning 
studies. 

I believe we have been good stewards of our 
investors’ capital, keeping headcount relatively 
low, while being laser focused on ensuring we 
have all the pieces in place for what lies ahead.

As we work to commercialize a medicine to 
address acquired SNHL, we recognize that 
there is no well-worn trail for us to follow, just 
as there is no precedent for hearing restoration 
medicines. While some may see this as a 
challenge, we view it as a unique opportunity 
to help establish the field, define a regulatory 
path, shape policy, and build the channels to 
reach patients and providers. We are working 
closely with advocacy organizations and key 
opinion leaders to understand where we 
can best support patients — both in terms 
of meaningful clinical outcomes and critical 
quality of life measures — while developing 
extensive health care professional, patient, and 
payor insights to guide strategy.

lost annually from 
unaddressed hearing 
loss. Unless action is 
taken, this figure will 
continue to rise in the 
coming decades. At the 
same time, investment 
in ear and hearing care 
has been shown to 
be cost–effective, and 
governments can expect 
a return of nearly 16 
International dollars for 
every 1 dollar invested.

Today, only approximately 20 percent of people 
who could benefit from hearing aids have 
them — providing a significant opening for 
new treatment options. While the specific 
populations we will be able to treat will be 
defined by our ongoing development studies, 
we believe that FX-322 may provide benefit to a 
substantial proportion of individuals with SNHL.

recognize the potential benefit of a treatment 
like FX-322 to provide a more holistic approach 
to patient care, and the opportunity to expand 
the scope of their practices. For both groups, 
there is agreement that the ability to enhance 
sound clarity and speech recognition is critical 
for patients — with the “Holy Grail” being able to 
do so in noisy environments.

For providers, neither otologists or 
otolaryngologists have non-device specific 
treatment options for their patients and are 
eager to adopt new interventions. Audiologists, 
both diagnostic and rehabilitative, also 

New treatments that restore and repair function 
will define the hearing restoration market. 
Hearing devices are not good analogs in this 
case, as their role is to address the symptoms 
and not the underlying cause of the condition.

Progenitor cells are preprogrammed stem cells that produce sensory hair cells in utero — and 
then remain dormant in the cochlea. FX-322 consists of two molecules designed to reactivate 
progenitor cells and regenerate missing sensory hair cells in the cochlea that when damaged 
can lead to hearing loss.

High-frequency 
Hearing 
Drives Speech 
Intelligibility

Fricative consonant sounds like “s,” “sh,” 
“f,” and “th” help us to tell words apart, 
but they’re some of the highest-pitched 
sounds in spoken language.

When patients develop hearing loss, 
they’re not only losing volume, they’re 
also losing the ability to distinguish 
between high-frequency sounds. Patients 
understand that someone is speaking, and 
can often make out lower-pitched vowel 
sounds, but they may fail to discriminate 
between high-pitched consonants. Think 
of the difference between words like “fail,” 
“sail,” and “tail.”

Hearing loss is the 
largest potentially 
modifiable risk 
factor for developing 
dementia.

— Dementia prevention, 

intervention, and care: 

2020 report of the Lancet 

Commission

Real-world impact is most important 
to patients, and for many, intelligibility 
improvements can have significant meaning. 
For some it can mean being able to use a 
phone, or to converse with loved ones, or to 
focus in school. Even more profound changes 
may include moving some patients out of 
hearing aids or allowing others to avoid cochlear 
implant surgery. 

This inability to understand and communicate 
can also have a considerable impact on human 
health, as hearing loss is associated with 
several other serious neurological conditions. 
A 2020 study in The Lancet identified hearing 
loss as the largest potentially modifiable risk 
factor for developing dementia, with other 
associated conditions including cognitive 
decline, depression, and injury from falls. Large, 
independent studies of these risks may further 
demonstrate the importance of hearing health 
on overall health. And, if causality between 
hearing loss and dementia is definitively shown, 
addressing hearing loss could have important 
economic and societal benefits in the  
years ahead.

Decline of Hearing and Communication

calls. Even one-on-one 
discussions were challenging 
when background noise was 
present.

At home with family and 
friends, Lorin began to miss 
some words, and eventually, 
he realized that hearing 
assistance was needed. 
Today, he wears hearing aids 
although hearing in noise 
continues to be an issue, 
as do quieter sounds and 
hearing on the phone. 

Now settled in Rochester, 
New York, home to one of 
the largest and most active 
chapters of the Hearing 
Loss Association of America 
(HLAA), Lorin finds support in 
his community and shares his 
own experiences with hearing 
loss to help others cope.

Growing up in Northern 
Wisconsin, Lorin G. helped out 
in his father’s farm machinery 
business, which exposed 
him to the loud noise of 
tractors and other powered 
equipment. These early 
experiences with cumulative 
noise exposure may have 
contributed to a gradual 
decline in his hearing, which 
he first noticed in his early 50s.

But that experience, along 
with a growing interest in 
electronics, also led him to the 
field of engineering, where he 
built a career focused on the 
design of electronic hardware 
and software products. During 
his career as an engineer, 
Lorin initially did not notice his 
hearing loss having an impact 
on communication with 
his co-workers. Eventually, 
however, group meetings 
in noisy settings became 
difficult, as did phone calls 
— and especially conference

Leadership,  
Momentum, Clarity

The year ahead and 2022 will be rich with data, 
providing critical insights into the patients 
FX-322 may best treat and its impact on 
measures of hearing. It will also be a year of 
planning. Study learnings from our Phase 2a 
and 111 studies have significantly enhanced our 
understanding of dosing and administration, 
while validating the hearing signal seen in the 
Phase 1/2 study. 

This year we will be active in several policy 
initiatives with regulators and policy experts 
on future hearing therapeutics, including 
sponsorship of an FDA-led Patient Focused 
Drug Development program, which will enable 
patients to speak directly to the FDA about their 
challenges with hearing loss and the need for 
new treatments.   

Our partnership with Astellas continues to 
flourish as they advance toward anticipated 
clinical studies in Europe and Asia. Our teams 

are working closely across functions, from 
development to chemistry, manufacturing and 
controls (CMC) to new product planning. Their 
focus and interest in hearing, regenerative 
medicine, and the broader ENT space has 
made them an ideal partner. We expect this 
relationship will continue to build over time.

We also will continue to broaden our portfolio 
and expand the potential of our PCA platform 
beyond hearing. We have built a world-class 
team and have made significant advances 
in our work on multiple sclerosis (MS). The 
Company continues to progress its preclinical 
program to support the advancement of a 
therapeutic candidate for remyelination in MS 
into the clinic. Lastly, we continue to look at new 
academic and commercial collaborations to 
expand our work into new disease areas where 
the activation of progenitor cells may have a 
profound impact on treating degenerative 
disease.

15

The year 2020 will always be remembered for 
the pandemic and how it changed the ways 
we work and live. We witnessed the fragility 
of our systems in the face of a virus, but also 
saw the remarkable courage of our healthcare 
workers. Our industry transformed the pace 
at which critical new treatments could be 
produced, relying on a steadfast commitment 
to science and innovation and an ability to work 
collaboratively across the public and private 
sectors. My hope is that this same energy and 
approach will be employed to help address a 
broad array of intractable diseases in the future. 

In April 2021, we moved into our new 
headquarters in Lexington, MA, bringing 
together colleagues from our Woburn, MA, 
and Farmington, CT, offices. While not at 
full capacity due to Covid, it is still exciting 
and highly gratifying to be able to bring our 
researchers together into new state-of-the art 
laboratories. Our team at Frequency met the 
challenge of the past year with grace, creativity, 
and selflessness, upending their lives and 
transforming the way they worked so we might 
continue to drive our programs forward. 

16

We are deeply grateful to all of those who 
contributed to our success and helped prepare 
us for our most important year as a company. 
This includes patients, who almost without fail, 
came to their follow-up visits during the height 
of the pandemic; the ENTs, who modified 
their practices to enable our clinical trials to 
continue; our academic and industry partners 
and those who continue to advise on our 
research and development programs; all our 
new employees, who recognized the potential 
of our approach; and our investors, who 
believed, and continue to believe in our vision.

We are working to advance a new mode 
of medicine in a therapeutic area where 
no treatments exist – something we never 
expected would be simple. However, we are 
confident in the potential of our regenerative 
medicine approach, both to transform the 
standard of care in the hearing field while 
creating long-term value for our investors. 

Like climbing any of the great peaks, you need 
the right equipment, the perseverance to 
withstand all types of weather, and the team 
to pull everyone to the top. We are building 
Frequency for the long term, and I believe the 
strength of our science and the expert team 
we have assembled will enable us to make 
remarkable progress in the months ahead as 
we work to reach the summit. 

For Frequency, striving for clarity is both 
a mission and a mantra, and today, the 
opportunity to bring a therapy to patients that 
can restore hearing and enhance speech clarity 
is no longer a faint whisper as its potential 
becomes increasingly clear.

and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements
to be materially different from any future results, performance or achievements expressed or implied by the forward-looking
statements.

In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,”
“anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential” or “continue”
or the negative of these terms or other similar expressions. The forward-looking statements in this Annual Report are only
predictions. We have based these forward-looking statements largely on our current expectations and projections about future
events and financial trends that we believe may affect our business, financial condition and results of operations. These
forward-looking statements speak only as of the date of this Annual Report and are subject to a number of important factors
that could cause actual results to differ materially from those in the forward-looking statements, including the risks,
uncertainties and assumptions described under the sections in this Annual Report titled “Risk Factors” and “Management’s
Discussion and Analysis of Financial Condition and Results of Operations.” These forward-looking statements are subject to
numerous risks, including, without limitation, the following:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the initiation, timing, progress and results of our preclinical and clinical trials and research and development of
programs, including our ongoing Phase 1b and Phase 2a clinical trials and any planned additional Phase 2 clinical
trials or Phase 3 clinical trials for FX-322 and our program to develop a product candidate for the treatment of
multiple sclerosis, or MS;

the impact of the novel coronavirus, COVID-19, on our ongoing and planned clinical trials, our research and
development activities and our business and financial markets;

our ability to continue to develop our progenitor cell activation, or PCA, platform and identify additional product
candidates;

our ability to successfully complete clinical trials of any product candidate and obtain regulatory approval for it;

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be
predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements
as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be
achieved or occur, and actual results could differ materially from those projected in the forward-looking statements.
Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is
not possible for management to predict all risk factors and uncertainties. As a result of these factors, we cannot assure you
that the forward-looking statements in this Annual Report will prove to be accurate. Except as required by applicable law, we
do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new
information, future events, changed circumstances, or otherwise.

You should read this Annual Report and the documents that we reference in this Annual Report completely and with
the understanding that our actual future results may be materially different from what we expect. We qualify that all of our
forward-looking statements by these cautionary statements.

RISK FACTORS SUMMARY

Our business is subject to numerous risks and uncertainties, including those described in Part I Item 1A. “Risk Factors”

in this Annual Report on Form 10-K. You should carefully consider these risks and uncertainties when investing in our
common stock. The principal risks and uncertainties affecting our business include the following:

• We are heavily dependent on the success of FX-322, our lead product candidate, which is still under clinical

development. If FX-322 does not receive regulatory approval or is not successfully commercialized, our business
will be materially adversely harmed;

• We utilize our PCA platform to develop product candidates that are designed to activate progenitor cells, which is a
new approach to therapeutic intervention and, as a result, successful development, approval, and commercialization
of our product candidates, including FX-322, is uncertain;

•

•

Clinical trials are expensive, time consuming, and difficult to design and implement, and involve an uncertain
outcome. The results of preclinical studies and early clinical trials are not always predictive of future results. Our
interim Phase 2a results, for example, showed that four weekly injections in subjects with mild to moderately severe
SNHL did not demonstrate improvements in hearing measures versus placebo. Any product candidate that we
advance into clinical trials may not achieve favorable results in later clinical trials, if any, or receive marketing
approval;

The regulatory approval processes of the FDA and comparable foreign regulatory authorities are lengthy, time
consuming, and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for FX-322
or any other product candidates, our business will be substantially harmed;

• 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, the choice of which may prove to be
wrong and adversely affect our business;

•

If we fail to comply with our obligations in our intellectual property licenses and funding arrangements with third
parties, or otherwise experience disruptions to our business relationships with our licensors, we could lose
intellectual property rights that are important to our business;

• We will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be

able to complete the development and commercialization of FX-322 and additional product candidates;

• We face significant competition from biotechnology, pharmaceutical, and medical device companies and our

operating results will suffer if we fail to compete effectively;

•

•

If we are unable to establish sales and marketing capabilities either on our own or in collaboration with third parties,
we may not be successful in commercializing any product candidate we develop, if approved; and

The COVID-19 pandemic has caused and could continue to cause disruptions to our business, including our
preclinical studies, clinical trials and operations and could adversely impact our financial condition and results of
operations.

Overview

PART I

We are a clinical-stage biotechnology company focused on harnessing the body’s innate biology to repair or reverse
damage caused by a broad range of degenerative diseases and a global leader in the science and development of medicines
for inner-ear cellular regeneration and hearing restoration. Our initial focus is on advancing our lead product candidate, FX-
322, through clinical studies with the goal of developing and commercializing a medicine to help millions of patients with the
most common form of hearing loss and build upon the potential of regenerative therapeutics for hearing. We believe we are a
leading company using mitotic regeneration for cochlear sensory hair cell regeneration and that FX-322 has the potential to
meaningfully improve overall hearing function and enhance quality of life.

Our proprietary approach, called Progenitor Cell Activation, or PCA, uses combinations of small molecules to activate
progenitor cells within the body to create functional tissue. These progenitor cells, which are closely related to stem cells, are
already resident in the targeted location in the body and programmed to develop and differentiate into specific cell types
within an organ, which we believe provide us the opportunity to pursue multiple proposed indications and develop potential
treatments for an array of degenerative diseases throughout the body. To that end, in addition to our lead program in hearing,
we are working to rapidly advance discovery efforts focused on using our PCA approach to potentially remyelinate nerves in
patients with multiple sclerosis, or MS and are advancing this program in collaboration with The Scripps Research Institute,
or Scripps, and Cambridge Enterprise Limited (the technology transfer arm of the University of Cambridge), or Cambridge.

Our hearing program is for a condition called sensorineural hearing loss, or SNHL, which is the most prevalent type of

hearing loss, typically caused by permanent loss of sensory hair cells in the cochlea within the ear. Cochlear sensory hair
cells can be lost by noise exposure, as a result of aging, certain viral infections or exposure to ototoxic drugs. FX-322 aims to
treat the underlying cause of SNHL by regenerating hair cells through the activation of progenitor cells already present in the
cochlea. In July 2019, we entered into a license and collaboration agreement, or the Astellas Agreement, with Astellas
Pharma Inc., or Astellas, under which we granted them rights to develop and commercialize FX-322 outside of the United
States. In September 2019, at the annual meeting of the American Academy of Otolaryngology, the principal investigator
from our Phase 1/2 clinical trial evaluating FX-322 in 23 patients with stable SNHL shared preclinical and clinical data that
showed that FX-322 was well-tolerated with no serious adverse effects and that we observed statistically significant and
clinically meaningful improvement in key measures of hearing loss, including word recognition, or WR, and clarity of sound.
Specifically, thirty-three percent (33%) of these subjects achieved a ten percent (10%) or greater absolute improvement in
WR scores in the treated ear. The study results were accepted for publication in the peer-reviewed journal Otology and
Neurotology and were published in February 2021. They were also presented at the 2021 Association for Research in
Otolaryngology 44th Annual Mid-Winter Meeting in February 2021.

In October 2019, we commenced dosing in a Phase 2a clinical trial of FX-322 and the FDA granted FX-322 Fast Track

designation. The goals of the trial are to further establish the hearing signal observed in the Phase 1/2 clinical trial, evaluate
the impact of multiple doses and provide insights on endpoints and patient population for further studies. In March 2021, we
announced topline, day-90 interim data from the Phase 2a clinical trial. The results showed that four weekly injections in
subjects with mild to moderately severe SNHL did not demonstrate improvements in hearing measures versus placebo. While
our interim data showed that WR scores increased across all groups, repeated weekly injections appeared to dampen the
hearing benefit observed compared to other single injection-studies. The interim results also showed an unexpected apparent
level of hearing benefit in the placebo group that did not occur in previous trials and exceeded well-established published
standards. No treatment-related serious adverse events were observed in the study.

In May 2020, we announced top-line data from an exploratory clinical study in Germany that we believe
demonstrated that FX-322 effectively reached the cochlea at levels predicted, based on computer models, to be
therapeutically active. Results from the exploratory study showed measurable concentrations of FX-322 in every sample
analyzed and that anatomical factors did not prevent FX-322 from reaching the cochlea. The study results were based on
analyzing samples of cochlear fluid, known as perilymph, taken intraoperatively from patients undergoing cochlear implant
surgery. A total of seven patients received a single intratympanic injection of FX-322, enabling researchers to directly
measure the level of FX-322 in perilymph, which is not otherwise feasible in inner-ear studies because accessing the cochlea
involves an invasive surgical procedure. Study patients were followed for approximately 30 days after the procedure and no
serious treatment related adverse events were observed. The results of this study were included in the article accepted for
publication in Otology and Neurotology and published in February 2021.

4

In June 2020, we shared preliminary findings from a longer-term, follow-up study of certain patients that had been

treated with FX-322 in the randomized portion of the Phase 1/2 clinical trial, where we observed improvements in certain key
measures of hearing loss. WR tests were performed for five patients at timepoints between 12- and 21-months following FX-
322 administration. Four of the patients that were observed to have statistically significant WR scores during the Phase 1/2
clinical trial were observed to have maintained the hearing benefit, three of which remained at statistically significant levels.
An additional patient who did not achieve a statistically significant improvement in WR during the Phase 1/2 clinical trial
was also retested and it was observed that the WR score had returned to baseline. The results of this study were presented at
the American Academy of Otolaryngology – Head & Neck Surgery meeting in September 2020.

In March 2021, we announced new data from a Phase 1b clinical trial of FX-322 designed to evaluate the impact of

injection conditions on tolerability. The data showed hearing improvement from a single injection of FX-322. In the multi-
center, randomized study, subjects with mild to severe SNHL (n=33) were injected in one ear with FX-322 with the untreated
ear as the control. Hearing function was tested over the course of 90 days following dosing. Thirty-two (n=32) subjects
completed the 90 day clinical assessment period and, at day 90 following dosing, thirty-four percent (34%) of these subjects
achieved a ten percent (10%) or greater absolute improvement in WR scores in the treated ear, which was clinically
meaningful and statistically significant compared to the untreated ear (p <0.05). This included a subset of subjects that more
than doubled their WR scores. The single dose had a favorable safety profile and was well tolerated.

We commenced a Phase 1b clinical trial of FX-322 for age-related hearing loss in October 2020. The clinical trial is a

double-blind, placebo-controlled, randomized multicenter safety study of up to 30 individuals aged 66-85 with mild to
moderately severe age-related hearing loss. The primary objectives of the Phase 1b study are to assess the local and systemic
safety of a single dose of FX-322 and evaluate hearing responses in an older adult cohort. Study participants will be
randomized 4:1 to receive either FX-322 or placebo in one ear. Validated measures of hearing including WR, WIN, and pure
tone audiometry will be used. Safety, otologic and audiologic assessments will be conducted at day 30 and 90 following
administration of FX-322 or placebo. We expect to share results from this clinical trial in the second quarter of 2021.

We commenced a Phase 1b clinical trial of FX-322 in patients aged 18-65 with severe SNHL in November 2020.

Severe SNHL is defined as a pure tone average deficit between 71-90 dB. Many patients with this clinical profile typically
would be candidates for cochlear implants. This clinical trial employs a similar design to the age-related Phase 1b clinical
trial that is currently underway. We expect to share results from this clinical trial in the third quarter of 2021.

To date, no drug therapies have been approved by the FDA or, to our knowledge, by other regulatory bodies, for the
treatment of SNHL. Existing devices such as hearing aids amplify sounds but do not replace hair cells, which have roles in
clarifying sound and improving speech intelligibility, particularly in noisy environments. Hearing aids also cannot repair the
underlying pathology of hearing loss. While hearing loss is often thought to be caused by aging, the condition is strongly
correlated with living in an industrialized society. According to the World Health Organization, or WHO, 1.5 billion people,
20% of the world’s population, suffer from some degree of hearing loss worldwide, and, according to the National Institutes
of Health, or NIH, more than 90% of people with hearing loss have SNHL. Based on our estimates, we believe that 41
million people in the United States alone have SNHL. The WHO also estimates that 1.1 billion children and adults ages 12 to
35 years old are at risk for hearing loss from recreational noise exposure.

Under the Astellas Agreement, Astellas is responsible for the development and commercialization of FX-322 outside of
the United States. As consideration for the licensed rights under the Astellas Agreement, Astellas paid us an upfront payment
of $80.0 million in July 2019 and has agreed to pay potential development milestone payments of up to $230.0 million.
Specifically, we would receive development milestone payments of $65.0 million and $25.0 million upon the first dosing of a
patient in a Phase 2b clinical trial for SNHL in Europe and Asia, respectively, and $100.0 million and $40.0 million upon the
first dosing of a patient in a Phase 3 clinical trial for SNHL in Europe and Asia, respectively. If the Astellas licensed
products are successfully commercialized, we would be eligible for up to $315.0 million in potential commercial milestone
payments plus tiered royalties on any future product sales ranging from low- to mid-teen percentages.

Our MS program focuses on activating oligodendrocyte progenitor cells in the central nervous system to repair the myelin
sheath that protects nerves and may have the potential to reverse damage done by the disease. We established an internal
research program using PCA to drive remyelination as a potential therapy for MS and have identified compounds that display
promising preliminary preclinical results in an in vivo model of remyelination. Our research efforts are focused on optimizing
these compounds and identifying a lead therapeutic candidate to advance into clinical trials. We have obtained worldwide
licenses for intellectual property from Scripps and Cambridge Enterprise on approaches to promote remyelination of nerve
fibers and are engaged in sponsoring clinical research to validate this approach at Cambridge University.

Impact of COVID-19

Our offices are located in states that are currently operating under a phased re-opening plan in response to the

COVID-19 pandemic. As of the date of the filing of this Annual Report, the majority of our employees continue to work
from home, while nearly a quarter to one-third of our workforce, consisting of mainly laboratory personnel, have periodically
worked in rotating teams to ensure the continuation of essential experiments. Our Farmington, CT research site, co-located
with the University of Connecticut, has resumed activity at a fifty percent level after a period of paused activity due to state
lock down orders previously in effect. While we have resumed experiments at our Farmington site, we have transitioned
certain key experiments to our offices in Woburn, MA and third parties and contract research organizations have been
engaged to advance certain projects. We are also have taken steps consistent with the FDA’s updated industry guidance for
conducting clinical trials.

The COVID-19 pandemic, and actions taken to mitigate it, have had and are expected to continue to have an adverse

impact on the economies and financial markets of many countries, including the geographical area in which we operate,
which could adversely impact our ability to raise additional capital when needed or on acceptable terms, if at all. In addition,
while no significant disruptions have occurred, the COVID-19 pandemic may cause such disruptions in our business or
operations, as well as the business and operations of our CMOs, CROs and other third parties with whom we conduct
business. The COVID-19 pandemic may also adversely impact our clinical trials, which could impede, delay, limit or prevent
the clinical development of our product candidates and ultimately lead to the delay or denial of regulatory approval of our
product candidates, which would materially adversely affect our business and operations, including our ability to generate
revenue.

Our product pipeline

The following table summarizes our PCA therapeutic candidate pipeline and discovery research programs:

Our team and history

Our company was founded in 2014 with the goal of creating medicines based on breakthrough research focused on

activating the body’s regenerative potential. In their groundbreaking research, Professors Robert S. Langer at the
Massachusetts Institute of Technology and Jeffrey Karp at Harvard Medical School, decoded the natural signals between
cells that make the intestine one of the most regenerative organs in the body through the continuous activation of progenitor
cells. Recognizing that similar progenitor cells were present but inactive in other organs, they discovered how to adapt these
natural signals using small molecules to temporarily activate progenitor cells in other organs, including the cochlea, and
create a localized healing response. Using these insights, we are developing FX-322 for the treatment of SNHL, and, in a

6

Phase 1/2 trial of FX-322 in stable hearing loss patients, we have observed statistically significant improvement in WR, a key
measure of hearing function. Further, we have identified several additional potential indications for our PCA platform and
expanded our team to incorporate domain expertise to pursue our goal of becoming a fully integrated biotechnology
company.

Our leadership team includes experienced biotech executives David L. Lucchino, our Chief Executive Officer and co-

founder, Christopher R. Loose, our Chief Scientific Officer and co-founder, Peter P. Pfreundschuh, our Chief Financial
Officer, Carl P. LeBel, our Chief Development Officer, Dana C. Hilt, our Chief Medical Officer, Quentin McCubbin, our
Chief Manufacturing Officer, Michael D. Bookman, our General Counsel, and Wendy S. Arnold, our Chief People Officer.
We have also assembled a world-class team of leaders in regenerative biology, otology, drug development, and drug delivery.
Our Clinical Advisory Board is comprised of leaders in hearing science and technology who shape how the community
thinks about hearing function and restoration. Our Regenerative Medicine Advisory Board members are at the forefront of
scientific discovery on the activation of progenitor cells and their potential application to therapeutic interventions in diseases
of multiple tissues and organs.

Our strategy

We intend to create and commercialize therapeutics to potentially transform the lives of patients by repairing or

reversing damage done to cells, tissue, and organs. To do so, we are implementing the following strategies:

•

•

•

•

Advance development of a single dose regimen of FX-322 for the treatment of SNHL. We believe our lead
product candidate has the potential to improve hearing function for the millions of patients affected by SNHL
who currently have no therapeutic options. We now have two independent, single-dose studies in patients with
mild to severe SNHL that showed a hearing signal with FX-322 and with statistically significant improvements
in speech intelligibility. The interim results from our Phase 2a study demonstrated that four weekly injections in
subjects with mild to moderately severe SNHL did not demonstrate improvements in hearing measures versus
placebo. Therefore, we plan to advance further development of FX-322 as a single dose regimen.

Establish our position as a global leader in the field of hearing function. We plan to continue to grow our
discovery organization and add experts in the field of otology to drive the optimization of our PCA approach for
the treatment of hearing loss. We also plan to expand our presence in the field of hearing restoration and to work
closely with the broader community of advocates, physicians, and payors to bring new treatments to patients
globally.

Expand the opportunities of our PCA platform beyond hearing. We believe our PCA platform has the potential
to address a wide range of clinical applications. We will continue to invest in research and development to
enhance our PCA platform with the goal of delivering new therapeutics in additional indications, such as diseases
of the muscle, gastrointestinal tract, skin, and bone. We identified MS as a disease where PCA has the potential
to produce a restorative effect by stimulation of oligodendrocyte precursor cells (OPCs) to myelinate axons. We
have obtained worldwide licenses for intellectual property from Scripps and Cambridge, on approaches to
promote remyelination of nerve fibers. We established an internal research program using PCA to drive
remyelination as a potential therapy for MS and have identified compounds that display promising preliminary
preclinical results in an in vivo model of remyelination. Our research efforts are focused on optimizing these
compounds and identifying a lead therapeutic candidate to advance into clinical trials. We have obtained
worldwide licenses for intellectual property from Scripps and Cambridge Enterprise on approaches to promote
remyelination of nerve fibers and are engaged in sponsoring clinical research to validate this approach at
Cambridge University.

Continue to build strategic collaborative relationships. Given the broad potential opportunity of our PCA
platform, we believe entering into strategic research, development, and commercial collaborations in select
therapeutic areas may provide an attractive avenue to facilitate the capital-efficient development of our PCA
platform and product pipeline. We believe these strategic collaborations could potentially provide significant
funding to advance our product candidates while allowing us to benefit from the development and therapeutic
area expertise of our collaborators. We may collaborate with large pharmaceutical companies, biotechnology
companies, and academic institutions to maximize the potential of our PCA platform to create new therapies for
patients.

Our approach: Progenitor cell activation within the body

We are pioneering a new class of small molecule therapeutics designed to activate progenitor cells already present
within the body to create healthy functional tissues and organs. We developed our PCA platform to identify combinations of
small molecules that selectively activate progenitor cells to regenerate tissues. Our initial therapeutic focus is SNHL. We
believe that our preclinical and clinical studies in SNHL have validated the potential of our PCA platform to provide a new
approach to regenerative medicine. Other potential applications of our PCA platform include, but are not limited to, diseases
of the muscle, gastrointestinal tract, skin, and bone.

The graphic below illustrates the application of our PCA platform to activate progenitor cells and create healthy
functioning target cells. Our small molecules are designed to activate key genes in a progenitor cell, which enable the cell to
go through asymmetric division, leaving behind a copy of the progenitor cell as well as creating a functional cell, such as a
hair cell. This asymmetric division process is a common mechanism used during the natural development and repair of
tissues.

Relationship between stem cells and progenitor cells

All cells in the human body arise from a single unspecialized, or undifferentiated, cell type called a pluripotent stem
cell. Two of the key characteristics of pluripotent stem cells are their ability to renew themselves through cell division and
the ability to differentiate into any cell type. Progenitor cells have similar self-renewal properties as pluripotent stem cells.
However, progenitor cells are programmed to develop and differentiate into specific cell types within an organ. This process
can be visualized using Waddington’s epigenetic landscape, which depicts a pluripotent stem cell as a ball rolling down a hill
as development progresses (see graphic below). As the ball commits to specific valleys, the cell becomes more specialized
and increasingly commits to a tissue-specific fate, such as a progenitor cell. The progenitor cells are programmed to create
specific cell types, and, in some cases, allow mature tissue and organs to repair and renew. However, researchers have
discovered that many organs throughout the human body that do not spontaneously regenerate do contain inactive progenitor
cells that, if stimulated, are potentially available to drive regeneration.

Over the course of several decades, multiple attempts have been made to harness the regenerative potential of stem

cells. More recently, the 2012 Nobel Prize in Physiology or Medicine was awarded to Dr. Shinya Yamanaka for discovering
how to create induced pluripotent stem cells by adding four genetic factors to a fully differentiated cell, as illustrated by the
solid black arrow in the graphic below. However, the Yamanaka factors cannot be applied in vivo, and it has proven
challenging to manufacture pluripotent or other human stem cells outside of the body and to control their differentiation to

8

produce a particular cell type. Further, delivering and properly integrating these cells back into the body adds substantial
complexity. Using another approach, some investigators have tried to force progenitor cells within the body to directly
convert into other cell types through a process called trans-differentiation, as illustrated by the dotted black arrow in the
graphic below. However, trans-differentiation may deplete progenitor cells, which reduces the target cell population for
future treatments.

We believe that our PCA approach bypasses the challenges presented by stem cell therapies by utilizing small molecule

therapeutics to temporarily reactivate progenitor cells that are already located at the tissue target site within the body and are
pre-programmed to make specific cell types. Our combinations of small molecules are designed to induce a progenitor cell to
temporarily enter an active state, where it then divides asymmetrically, replacing itself (blue arrows) and regenerating a
desired cell type (orange arrow). Asymmetric division occurs when organs naturally regenerate, so progenitor cells are
thought to be maintained for future use.

Key attributes of our PCA platform

Our discoveries in regenerative medicine allow us to activate the innate and under-utilized capabilities of progenitor
cells. We believe our PCA platform represents a transformative step in the evolution of regenerative medicine by providing
the following key attributes:

•

•

•

Activates progenitor cells in the right location. We overcome the major challenge of delivering and integrating
cells into the proper location within tissue. Our small molecule therapeutic candidates activate the body’s own
progenitor cells at the desired location in targeted tissues.

Enables ease of manufacturing. We eliminate the need to remove and grow live cells ex vivo, which can be
costly and complex to manufacture, difficult to control quality, and may pose potential safety risks. In contrast,
our small molecule therapeutic candidates will be produced using standard manufacturing methods.

Avoids permanent genetic changes.
activate the innate genes that play a central role in the development of organs and tissues. This small molecule
approach could create a disease-modifying or restorative effect without changing the body’s genetic code. In
addition, we believe we avoid the risk of acquiring immune reactivity to our therapeutics, which is commonly
associated with genetically modifying cells.

Instead of altering genes, our small molecules are designed to temporarily

Our therapeutic discovery process

We utilize a proprietary process to identify small molecule combinations for activating progenitor cells.

•

Discovery in the right context. Traditional drug screening uses immortalized cell lines that are convenient for
use in a laboratory but may not reflect the complex biology of tissue-specific cell types in the body. In our

9

discovery process, we develop primary progenitor cell assays that are designed to maintain these cells in their
natural state in order to increase the likelihood of successful drug discovery and translation into an effective
tissue-specific therapeutic.

•

Decoding and controlling activation pathways for progenitor cells. We use our accumulated insights into
progenitor cell signaling and aging to identify biological pathways that may activate a specific progenitor cell.
We then select and apply combinations of small molecules from our proprietary toolbox of compounds to
modulate the chosen biological pathways and achieve PCA.

By assessing our small molecule combinations in a highly relevant context, we and our collaborators have applied this

discovery process to identify compounds that activate progenitor cells in numerous tissues.

Our hearing program

We first applied our PCA platform to create FX-322, our lead product candidate designed to restore hearing function in

patients with SNHL. We completed a Phase 1/2 clinical trial in 23 patients with stable SNHL in which we observed a
statistically significant improvement in WR, a key measure of hearing function, and FX-322 was observed to be well-
tolerated. Specifically, thirty-three percent (33%) of these subjects achieved a ten percent (10%) or greater absolute
improvement in WR scores in the treated ear. In May 2020, we shared clinical data that showed delivery of FX-322 to the
cochlea at levels predicted to reach the therapeutically active range of the treatment. In September 2020, at the American
Academy of Otolaryngology annual meeting, we presented data showing sustained improvements in speech intelligibility and
audibility measures in patients up to 21 months after receiving an initial dose of FX-322 in our Phase 1/2 study. The Phase
1/2 and cochlear delivery study results were accepted for publication in the peer-reviewed journal Otology and Neurotology
and were published in February 2021. We believe that FX-322 has the potential to meaningfully improve overall hearing
function and significantly enhance quality of life for patients with hearing loss.

In October 2019, we commenced dosing in a Phase 2a clinical trial of FX-322 and the FDA granted FX-322 Fast Track

designation. The goals of the trial are to further establish the hearing signal observed in the Phase 1/2 clinical trial, evaluate
the impact of multiple doses and provide insights on endpoints and patient population for further studies. In March 2021, we
announced topline, day-90 interim data from the Phase 2a clinical trial. The results showed that four weekly injections in
subjects with mild to moderately severe SNHL did not demonstrate improvements in hearing measures versus placebo. No
treatment-related serious adverse events were observed in the study. In the four-arm Phase 2a study, 95 subjects aged 18-65
are being evaluated for hearing improvement using WR, Words-In-Noise, or WIN, pure tone audiometry and additional
exploratory measures. All subjects were administered a total of four weekly intratympanic injections comprised of zero, one,
two, or four doses of FX-322 with the balance of injections comprised of placebo doses. While our interim data showed that
WR scores increased across all groups, repeated weekly injections appeared to dampen the hearing benefit observed
compared to other single injection-studies. The Phase 2a interim results also showed an unexpected apparent level of hearing
benefit in the placebo group that did not occur in previous trials and exceeded well-established published standards,
potentially suggesting bias due to trial design. Given these challenges observed in the Phase 2a study design, the interim
results showed no discernible hearing benefit of FX-322 over placebo.

In May 2020, we announced top-line data from an exploratory clinical study in Germany that we believe
demonstrated that FX-322 effectively reached the cochlea at levels predicted, based on computer models, to be
therapeutically active. Top-line results from the exploratory study showed measurable concentrations of FX-322 in every
sample analyzed and that anatomical factors did not prevent FX-322 from reaching the cochlea. The study results were based
on analyzing samples of cochlear fluid, known as perilymph, taken intraoperatively from patients undergoing cochlear
implant surgery. A total of seven patients received a single intratympanic injection of FX-322, enabling researchers to
directly measure the level of FX-322 in perilymph, which is not otherwise feasible in inner-ear studies because accessing the
cochlea involves an invasive surgical procedure. Study patients were followed for approximately 30 days after the procedure
and no serious treatment related adverse events were observed. The study results were accepted for publication in the peer-
reviewed journal Otology and Neurotology and were published in February 2021.

In June 2020, we shared preliminary findings from a longer-term, follow-up study of certain patients that had been

treated with FX-322 in the randomized portion of the Phase 1/2 clinical trial, where we observed improvements in certain key
measures of hearing loss. WR tests were performed for five patients at timepoints between 12- and 21-months following FX-
322 administration. Four of the patients that were observed to have statistically significant WR scores during the Phase 1/2
clinical trial were observed to have maintained the hearing benefit, three of which remained at statistically significant levels.
An additional patient who did not achieve a statistically significant improvement in WR during the Phase 1/2 clinical trial
was also retested and it was observed that the WR score had returned to baseline. The results of this study were presented at
the American Academy of Otolaryngology – Head & Neck Surgery meeting in September 2020.

10

In March 2021, we announced new data from a Phase 1b clinical trial of FX-322 designed to evaluate the impact of
injection conditions on tolerability. The data showed hearing improvement from a single injection of FX-322. In the multi-
center, randomized study, subjects with mild to severe SNHL (n=33) were injected in one ear with FX-322 with the untreated
ear as the control. Hearing function was tested over the course of 90 days following dosing. Thirty-two (n=32) subjects
completed the 90 day clinical assessment period and, at day 90 following dosing, thirty-four percent (34%) of these subjects
achieved a ten percent (10%) or greater absolute improvement in WR scores in the treated ear, which was clinically
meaningful and statistically significant compared to the untreated ear (p <0.05). This included a subset of subjects that more
than doubled their WR scores. The single dose had a favorable safety profile and was well tolerated.

As shown in the graph below, we now have two independent, single-dose studies in patients with mild to severe SNHL

that showed a hearing signal with FX-322 and with statistically significant improvements in speech intelligibility.

Impact and prevalence of hearing loss

According to the WHO, 1.5 billion people suffer from some degree of hearing loss worldwide, and, according to the

NIH, more than 90% of people with hearing loss have SNHL. Based on our estimates, we believe that approximately
41 million people in the United States alone have SNHL. The WHO also estimates that 1.1 billion children and adults ages 12
to 35 years old are at risk for hearing loss from recreational noise exposure. In middle- and high-income countries, the WHO
estimates that nearly 50% of people aged 12 to 35 listen to personal audio devices at unsafe sound levels. Moreover, damage
from noise exposure in early childhood can render the ears more susceptible to the effects of aging. Noise exposure is
difficult to avoid in modern society. Noise at restaurants, for example, routinely climbs into the high 70-decibel, or dB, range,
equivalent to a canister vacuum cleaner, and sometimes to the mid-80 dB, as loud as a nearby diesel truck.

11

U.S. prevalence of SNHL, ranging from mild to moderate to severe, is shown in the graph below, which is from data

from the National Center for Health Statistics (NCHS). Each SNHL patient population is being studied in the current FX-322
clinical program.

After a patient first complains of hearing loss, which is most often to their primary care physician, patients with SNHL

are managed by audiologists and otolaryngologists, who are trained as ear, nose, and throat specialists, or ENTs. In the
United States, there are about 13,000 audiologists and about 12,500 ENTs. Developing a therapeutic to potentially modify an
underlying cause of SNHL may provide a critically important treatment option for this group of health-care providers and
their patients.

There are also further direct and indirect impacts on individuals suffering from SNHL. Hearing loss profoundly affects
an individual’s ability to participate in the social interactions of daily life, which can lead to feelings of loneliness, isolation,
and frustration. Untreated hearing loss is associated with a 50% increase in dementia and a 40% increase in depression.
Adults with hearing loss also have higher unemployment rates than non-hearing-impaired adults, and a relationship between
hearing loss and diminished employment and advancement opportunities has been reported. According to a 2020 study in the
medical journal The Lancet, hearing loss is the largest modifiable risk factor for developing dementia.

12

Biology and measurement of hearing

As shown in the figure below, we hear sounds when sound waves enter the inner ear and generate movement of the
fluid in the cochlea, a portion of the inner ear that looks like a snail shell. This fluid movement causes hair cells within the
cochlea to bend and in turn generate electrical signals that are transmitted to the brain via the auditory nerve. The cochlea is
arranged so that hair cells at the base detect high frequencies and hair cells at the apex detect low frequencies.

Humans are born with about 15,000 hair cells in the cochlea of each ear. Hair cells are commonly lost due to noise

exposure in work settings, travel or leisure activities, or as a result of aging, certain viral infections or exposure to ototoxic
drugs. Lost hair cells do not spontaneously regenerate. Over time, hearing loss can accumulate with greater prevalence at
high frequencies. The left panel of the figure below shows a picture of the inside of a healthy cochlea, with one row of inner
hair cells, or IHCs, and three rows of outer hair cells, or OHCs. OHCs amplify or dampen sound volume and tune the cochlea
to detect specific frequencies. IHCs convert sound waves into nerve impulses that are sent to the auditory nerve. Functional
hair cells allow the auditory system to focus on a sound and filter it appropriately throughout the cochlea. The right panel in
the below image, adapted from Ryan AF PNAS 2000, shows a cochlea after noise damage, with both IHCs and OHCs
missing.

Healthy and Noise-Damaged Cochlea

The two primary components for hearing testing are intelligibility, or the ability to understand spoken words, and the
audibility or loudness of sound. While amplifying devices such as hearing aids can make sounds louder, they have limited
ability to improve intelligibility, particularly in noisy environments. Intelligibility is particularly important to understand
speech in social settings such as in meetings or at restaurants, where filtering sound is critical for communication.

13

Intelligibility is typically measured by playing a list of words that are repeated back by the person being tested and
scoring based on the number of words that the person gets correct. The two validated testing methods of speech intelligibility
that are most widely used by audiologists are: word recognition, or WR, where patients are asked to identify monosyllabic
words delivered at a loud, but conversational volume level, and words-in-noise, or WIN, where patients are asked to identify
monosyllabic words in the presence of background, multi-talker noise.

Audibility is determined by measuring hearing function at different levels of loudness and pitch or frequency. Patients
are most often tested using pure tone audiometry, in which a tone is played at a particular frequency and patients are asked to
indicate whether they can hear the tone at varying levels of loudness. Loudness is recorded in dB HL. Frequency is recorded
in Hertz, or Hz, and is generally measured in the range of 250 to 8000 Hz. According to the WHO, normal hearing is defined
as the ability to hear sounds at a loudness value of less than 26 dB HL, which is the average of loudness values measured at a
range of low, middle, and high frequencies, such as 500, 1000, 2000, and 4000 Hz. The larger the loudness value needed for
a patient to hear sounds the greater the decline in hearing function, or more severe hearing loss. The graphic below depicts
the severity of hearing loss across a range of frequencies based on the American Speech-Language-Hearing Association
scale.

Limitations of current treatment options

Current treatment options for hearing loss have significant limitations and none are disease modifying. The only
available treatments for hearing loss are hearing aids, or in extreme cases, cochlear implants. No drug therapies have been
approved by the FDA or, to our knowledge, by other regulatory bodies, for the treatment of SNHL.

Hearing aids

Hearing aids help many patients cope with mild-to-moderate hearing loss and are used or have been tried by more than

10 million patients in the United States. Only one in four patients with hearing loss has ever used hearing aids, and
approximately half of patients who seek medical assistance for their hearing loss do not get hearing aids. Limitations of
hearing aids include:

•

•

Poor sound quality. Hearing aids amplify sounds, allowing patients to perceive sounds that would otherwise be
too soft for them to hear, but do not address the loss of hair cells, which determine sound quality and
intelligibility, particularly in noisy environments.

Challenges in social settings. The wide range of frequencies and sharp tuning provided by hair cells enables the
auditory system to accurately recognize and distinguish different sounds, allowing the brain to focus on a single
sound source. Hearing aids on the other hand typically amplify all sounds and do not enable this important

14

•

•

•

sound-processing capability. As a result, interactions in social settings, which require distinguishing one speaker
among many sound sources, are significantly impaired.

Difficulties with background noise. Patients with hearing loss may become more sensitive to background noise,
and many patients with hearing aids turn them off in noisy environments.

Stigma associated with wearing a visible device. Some patients refuse to wear hearing aids, or do not wear them
regularly, as they do not want to be stigmatized or identified as having a physical handicap.

Need for maintenance. Hearing aids must be replaced, on average, every four to six years, need regular battery
replacement, and can require repair due to damage during use. Medicare and most private insurance plans do not
pay for hearing aids, and most patients must pay for these devices out of pocket.

Cochlear Implants

Patients with severe or profound hearing loss who have not been helped by hearing aids may be candidates for a
cochlear implant. Of the roughly one million people in the United States who qualify, only about 100,000 patients have
cochlear implants. Cochlear implants comprise an external microphone, sound processor and transmitter system, which
receive sounds from the environment, and an implanted receiver and electrode system that directly stimulates the auditory
nerve. Cochlear implants do not mimic natural hearing, and patients with cochlear implants need to learn to interpret the low-
resolution electric signal produced by the device as sound. Cochlear implants also require an invasive, costly surgical
procedure.

Our lead product candidate: FX-322

Using our PCA platform, we are developing our lead product candidate, FX-322, for the treatment of SNHL. FX-322 is

designed to treat the underlying cause of SNHL by regenerating hair cells through activation of progenitor cells already
present in the cochlea. We believe that FX-322 has the potential to meaningfully improve overall hearing function and
significantly enhance quality of life for patients with hearing loss.

Mechanism of Action

By studying the most regenerative organ in the body, the intestine, we discovered that signaling for proliferation and

differentiation among stem cells could be replicated with small molecules. Specifically, activating the Wnt pathway, which is
fundamental for cell growth, using a glycogen synthase kinase 3, or GSK3, inhibitor and inhibiting histone deacetylase, or
HDAC, caused intestinal stem cells expressing the protein Lgr5 to proliferate. The inner ear contains progenitor cells with the
Lgr5 protein that do not regenerate on their own. On the hypothesis that these progenitor cells lacked the signals required for
regeneration, we applied a GSK3 inhibitor and HDAC inhibitor to these cells and found that they proliferated and
regenerated lost hair cells. Based on this discovery, we created FX-322, which is a proprietary combination of an FDA-
approved HDAC inhibitor, sodium valproate, and a new chemical entity that inhibits GSK3.

Administration

FX-322 is our proprietary thermoreversible polymer formulation that is administered through the eardrum, or
intratympanically, into the middle ear in a procedure that takes approximately 10 to 15 minutes. The intratympanic
administration procedure is generally well-tolerated and is routinely performed by ENTs as an office-based procedure. FX-
322, which is liquid at room temperature, gels at body temperature inside the middle ear, allowing the active ingredients to
diffuse into the inner ear and reach the cochlea. Similar thermoreversible polymer formulations have been used in FDA-
approved products for other indications in the ear.

15

The image below shows delivery of FX-322 via intratympanic injection.

Preclinical studies

Prior to commencing clinical trials, we tested FX-322 in multiple preclinical studies, including in human cells ex vivo

and functional hearing tests in mice in vivo. In in vitro testing of isolated human inner ear progenitor cells with the
compounds comprising FX-322, we observed the formation of new progenitor cells and their subsequent conversion into hair
cells. We also observed translation across species in our in vitro studies of the inner ear progenitor cells from rhesus
macaques in which a similar expansion of cell numbers were observed as in the in vitro studies of human cells.

We also conducted ex vivo testing in intact cochlea isolated from mice. To cause hair cell loss, we exposed the cochlea

for 16 hours to an aminoglycoside antibiotic that is toxic to hair cells. We then treated the cochlea for 72 hours with the
compounds comprising the active agents in FX-322. Aminoglycoside treatment (left panel in the figure below) killed more
than 80% of the hair cells in the cochlea (shown in green). By contrast, cochlea treated with the compounds in FX-322
(shown in the right panel) regenerated hair cells to a near native level, as shown graphically in the right panel.

Restoration of Hair Cells in Mouse Cochlea

16

We also tested FX-322 in a mouse model of severe noise-induced hearing loss. Following noise exposure, 47 mice

were treated with FX-322 and 37 were treated with placebo. Hearing function was measured using auditory brainstem
response, or ABR, in which the signal generated by the auditory nerve upon sensing sound is detected by electrodes on the
scalp. We performed ABR testing after 24 hours, and measured hearing recovery after 30 days. The figure below shows the
percentage of mice treated with FX-322 (shown in orange) or with placebo (shown in blue) that achieved a hearing recovery
of at least 10 dB at 20000 Hz, a mid-range frequency for mice. The improvement observed in the placebo-treated mice was
due to recovery of temporary effects not related to hair cell death, which is typical following acute hearing loss.

Hearing Recovery in Mice Treated with FX-322

We have also conducted pharmacokinetic tests in multiple species in which we observed that FX-322 administration

achieved therapeutic levels of the active pharmaceutical ingredients in the cochlea.

Clinical results

Phase 1/2 clinical trial

We conducted a Phase 1/2 clinical trial of FX-322 in which we enrolled 23 adult patients aged 33 to 64 with an
established diagnosis of mild to moderately severe stable SNHL, defined as the average pure tone value of 26 to 70 dB at the
500, 1000, 2000 and 4000 Hz frequencies, who had no change of 10 db or more at any frequency for more than six months.
Fourteen patients had mild SNHL and nine patients had moderate to moderately severe SNHL. Of the nine moderate to
moderately severe patients, six were randomized to FX-322 and three to placebo. In this trial, 15 patients were treated with a
single injection of FX-322 and eight patients received placebo. Each patient had a documented medical history consistent
with either noise-induced hearing loss, or NIHL, typically from noise exposure at work, or sudden SNHL, or SSNHL, which
is characterized as a loss of 30 dB at three adjacent frequencies occurring over a 72-hour period. All patients had stable
SNHL, meaning their hearing function at study entry was not significantly different based on a documented audiogram from
at least six months prior to the study. Hearing function, specifically speech intelligibility, was assessed using WR and WIN.
Hearing loudness was also measured using pure tone audiometry. Patients were randomized to a single injection of FX-322
or placebo administered at one of two different dose volumes (0.05 mL and 0.2 mL) to assess the safety of FX-322
administration and systemic exposure to FX-322. Follow-up visits occurred at 15, 30, 60, and 90 days after injection.

17

The objectives of the trial were to assess:

•

•

•

the systemic safety of FX-322;

the plasma pharmacokinetic profile to determine the systemic exposure to FX-322; and

the effect of FX-322 on measures of ear health and hearing function.

FX-322 was observed to be well-tolerated in this trial. No serious adverse events were observed, and all treatment-

related adverse events were mild, procedure-related, and generally resolved within minutes after dosing. We also observed
limited concentrations of the FX-322 components in systemic circulation.

In addition to the prospective analysis, we conducted a prospective statistical analysis where we tested whether the Day
90 WR value for each patient fell outside of the 95% confidence interval compared to their baseline WR value. A confidence
interval, or CI, is a range of values in which, statistically, there is a specified level of confidence where the result lies. In this
patient-by-patient analysis, we observed statistically significant and clinically meaningful increases in WR in four of 15
patients treated with FX-322 at Day 90, who were among the six FX-322 patients that had moderate to moderately severe
SNHL (as shown in the figure below).We also observed improvements for the two remaining FX-322 patients in the study
that had moderate to moderately severe SNHL in the range of 30-50% from their baseline score, but these improvements
were not statistically significant.

In June 2020, we shared preliminary findings from a follow-up study we conducted that assessed durability of the WR

improvements beyond 90 days at a single follow-up visit from 407 to 639 days post−FX-322 administration in five of the
subjects that showed a response in the Phase 1/2 trial (the 6th patient was unable to participate in the follow-up study). The
mean percentage of words correct in the treated ear was 38.4% at baseline, 69.6% at day 90, and 54.8% at follow-up. Three
of five subjects showed statistically significant improvements in WR at the follow-up visit compared to baseline (see
following figure). We believe that the results suggest that a single dose of FX-322 can result in durable improvements in
speech intelligibility and support further investigation of the efficacy of FX-322.

There was no apparent association between WR improvements and whether the patients had stable NIHL, or stable
SSNHL, and similar results were obtained with both dose volumes. This is consistent with published work showing drug
delivery to the cochlea depends more on the concentration of the drug than the volume of injection. There were no clinically
meaningful WR improvements observed in the placebo group.

We also performed a post hoc analysis on WR and WIN data for the Phase 1/2 study. The analysis showed a

statistically significant improvement in WR by all FX-322-treated patients versus all placebo patients (p=0.010). A p value is
the probability that the difference between two data sets was due to chance. The smaller the p value, the more likely the
differences are not due to chance alone. In general, if the p value is less than or equal to 0.05, the outcome is statistically
significant. The data in the figures below are presented as adjusted mean relative percent change from baseline. FX-322
treated patients saw improvements in WR as early as 15 days after treatment that were sustained over 90 days.

18

As shown in the figure below for WIN, the adjusted mean relative percent change from baseline was assessed at 15, 30,

60, and 90 days after injection, and a trend in improvement was seen in FX-322-treated patients versus placebo. Also, there
were non-statistically significant trends in improved WIN scores at Day 90 in the four FX-322, treated patients that had
statistically significant and clinically meaningful improvements in WR in the prospective statistical analysis.

The same WR data was published in Otology and Neurotology in February 2021, as shown in the figure below. In

compliance with the publication’s policy, the data was presented with standard error, resulting in a slightly different adjusted
mean and p value. Despite the change, the results were consistent with the figure above.

19

As shown in the figure below, published in Otology and Neurotology in February 2021, speech recognition in a noisy
background also improved over time for FX-322-treated patients versus placebo patients. Performance was quantified as the
signal-to-noise ratio, or SNR, consistent with 50% correct WR, with lower SNR values indicating better speech perception in
background noise. Analyses showed a significant improvement in average SNR from baseline to Day 90 in FX-322-treated
patients versus placebo patients.

We also assessed audiometric changes from 250 Hz to 8000 Hz for all patients. Since drug enters closest to the high

frequency region, the greatest drug exposure is expected to occur in the high frequency region. While no statistical
differences were observed at any frequency when comparing pooled treatment groups, four of the moderate to moderately
severe FX-322 patients showed a 10 dB threshold improvement at 8000 Hz at Day 90.

Phase 2a clinical trial

Based on our analysis of the data from our Phase 1/2 clinical trial, we initiated a randomized, double-blind, placebo-

controlled, single- and repeat-dose Phase 2a clinical trial of FX-322 in the fourth quarter of 2019. In September 2020, we
completed enrollment of 95 patients across 16 sites in the Phase 2a clinical trial. As in the Phase 1/2 clinical trial, patients
were required to have a documented medical history consistent with either stable NIHL or stable SSNHL, meaning that a
patient’s hearing deficit has remained consistent over a defined period of time based on a patient’s audiograms. All subjects
in the clinical trial have meaningful WR deficits including patients who are considered to have “mild” hearing loss.

To explore how a single dose compares to multiple doses of FX-322, we randomized patients to one of four groups,
each of which received four injections, once per week at weekly intervals starting at the initial visit. Group 1 received one
injection of FX-322 and three injections of placebo. Group two received two injections of FX-322 and two injections of
placebo. Group three received four injections of FX-322. Group four received four injections of placebo. Patients have
follow-up visits two weeks after dosing and then monthly for seven months. The efficacy endpoints of this trial are WR,
WIN, and pure tone audiometry in the range of 250 to 8000 Hz. The exploratory efficacy endpoints are the TFI, the HHIA,
and pure tone audiometry in the range of 9000 to 16000 Hz. The selection of the efficacy endpoints in this study builds on the
learnings from the Phase 1/2 trial, and we believe will add to our knowledge on the potential ways in which FX-322 may
improve hearing function.

In March 2021, we announced topline, day-90 interim data from the Phase 2a clinical trial. The results showed that four

weekly injections in subjects with mild to moderately severe SNHL did not demonstrate improvements in hearing measures
versus placebo. No treatment-related serious adverse events were observed in the study. In the four-arm Phase 2a study, 95
subjects aged 18-65 were evaluated for hearing improvement using WR, WIN, pure tone audiometry and additional
exploratory measures. All subjects were administered a total of four weekly intratympanic injections comprised of zero, one,
two, or four doses of FX-322 with the balance of injections comprised of placebo doses. While WR scores increased across
all groups, the interim data showed that repeated weekly injections appeared to dampen the hearing benefit observed
compared to other single injection-studies. The Phase 2a interim results also showed an unexpected apparent level of hearing

20

benefit in the placebo group that did not occur in previous trials and exceeded well-established published standards,
potentially suggesting bias due to trial design. Given these challenges observed in the Phase 2a study design, there was no
discernible hearing benefit of FX-322 over placebo. We plan to report an analysis of the end of Phase 2a data (210 days) late
in the second quarter of 2021.

Phase 1b clinical studies

In March 2021, we announced new data from a Phase 1b clinical trial of FX-322 designed to evaluate the impact of

injection conditions on tolerability. The results showed hearing improvement from a single injection of FX-322. In the multi-
center, randomized study, subjects with mild to severe SNHL (n=33) were injected in one ear with FX-322 with the untreated
ear as the control. Hearing function was tested over the course of 90 days following dosing. Thirty-two (n=32) subjects
completed the 90 day clinical assessment period and, at day 90 following dosing, thirty-four percent (34%) of these subjects
achieved a ten percent (10%) or greater absolute improvement in WR scores in the treated ear, which was clinically
meaningful and statistically significant compared to the untreated ear (p <0.05). This included a subset of subjects that more
than doubled their WR scores. The single dose had a favorable safety profile and was well tolerated.

We commenced a Phase 1b clinical trial of FX-322 for age-related hearing loss in October 2020. The clinical trial is a

double-blind, placebo-controlled, randomized multicenter safety study of up to 30 individuals aged 66-85 with mild to
moderately severe age-related hearing loss. The primary objectives of the Phase 1b study are to assess the local and systemic
safety of a single dose of FX-322 and evaluate hearing responses in an older adult cohort. Study participants will be
randomized 4:1 to receive either FX-322 or placebo in one ear. Validated measures of hearing including WR, WIN, and pure
tone audiometry will be used. Safety, otologic and audiologic assessments will be conducted at day 30 and 90 following
administration of FX-322 or placebo. We expect to share results from this clinical trial in the second quarter of 2021.

We commenced a Phase 1b clinical trial of FX-322 in patients aged 18-65 with severe SNHL in November 2020.

Severe SNHL is defined as a pure tone average deficit between 71-90 dB. Many patients with this clinical profile typically
would be candidates for cochlear implants. This clinical trial employs a similar design to the age-related Phase 1b clinical
trial that is currently underway. We expect to share results from this clinical trial in the third quarter of 2021.

Other Clinical Studies

In May 2020, we announced top-line data from an exploratory clinical study in Germany that we believe
demonstrated that FX-322 effectively reached the cochlea at levels predicted, based on computer models, to be
therapeutically active. Top-line results from the exploratory study showed measurable concentrations of FX-322 in every
sample analyzed and that anatomical factors did not prevent FX-322 from reaching the cochlea. The study results were based
on analyzing samples of cochlear fluid, known as perilymph, taken intraoperatively from patients undergoing cochlear
implant surgery. A total of seven patients received a single intratympanic injection of FX-322, enabling researchers to
directly measure the level of FX-322 in perilymph, which is not otherwise feasible in inner-ear studies because accessing the
cochlea involves an invasive surgical procedure. Study patients were followed for approximately 30 days after the procedure
and no serious treatment related adverse events were observed. The study results were included in the article accepted for
publication in the journal Otology and Neurotology and were published in February 2021.

Our multiple sclerosis (MS) program

We have initiated a discovery and preclinical program in MS after identifying MS as a degenerative disease that has the
potential to be treated with small molecules that activate oligodendrocyte progenitor cells, or OPCs, leading to remyelination.
In 2017, we initiated a relationship with Scripps, where researchers had discovered that anti-muscarinic and other classes of
pharmacologic agents activate OPCs in the brain. We are pursuing this and other approaches to stimulating myelination of
axons in MS. Oligodendrocytes are responsible for making myelin, which accelerates the conduction of information through
the brain and provides metabolic support for axons. We believe that stimulating progenitor cells in the central nervous system
to grow oligodendrocytes and remyelinate axons could potentially reverse the damage caused by the immune system in MS.
The presently approved therapies for MS suppress demyelination but do not repair the damage to myelin.

The potential for anti-muscarinic drugs to treat the symptoms of MS was supported by an independently-run, double-

blinded Phase 2 cross-over study entitled Clemastine Fumarate as a Remyelinating Therapy for Multiple Sclerosis
(ReBUILD), conducted at the University of California, San Francisco. In the ReBUILD study, 50 adult, relapsing-remitting
MS patients with optic neuropathy were randomized to either clemastine, which has anti-muscarinic and anti-histaminic
activity, or placebo, both in combination with standard of care. The primary endpoint of the study was visual evoked
potential latency, or VEP, a test commonly used for optic neuritis and other demyelinating events, such as MS. Patients

21

treated with clemastine showed an improvement in VEPs indicating remyelination of optic nerve axons. The results of this
study were published in the medical journal The Lancet and showed a statistically significant improvement in VEP in
patients treated using a single agent, clemastine. Other agents which have been reported to show remyelinating activity in MS
patients include a Histamine receptor 3 (H3) inverse agonist and Bexarotene (an RXR antagonist). In all of the above studies
the remyelinating effects were reported based on measures of nerve function (electrophysiology) or imaging (MRI imaging).
These methods are considered to be measures or biomarkers of the degree of remyelination, supporting the idea that
remyelination may be possible in MS patients.

We have been applying our expertise in finding synergistic combinations of small molecules for activating progenitor

cells to the treatment of MS. We believe that combinations of the agents may be more active than single agents such as
clemastine. The increased remyelination activity may lead to a clinical benefit in patients with MS. We have licensed the
worldwide rights to the related Scripps patent estate and are continuing to advance this discovery both on our own and
through a sponsored research arrangement with Scripps. Through this work we have discovered combinations that enhance
both in vitro and in vivo remyelination over single agents, and have obtained a worldwide, exclusive license from Cambridge
for one such combination. We established an internal research program using PCA to drive remyelination as a potential
therapy for MS and have identified compounds that display promising preliminary preclinical results in an in vivo model of
remyelination. Our research efforts are focused on optimizing these compounds and identifying a lead therapeutic candidate
to advance into clinical trials. We have obtained worldwide licenses for intellectual property from Scripps and Cambridge
Enterprise on approaches to promote remyelination of nerve fibers and are engaged in sponsoring clinical research to validate
this approach at Cambridge University.

In 2020 we established an internal research and discovery effort to identify novel compounds that activate OPCs and
induce remyelination in animal models of MS. The goal of the program is to identify product candidates that are novel and
that show significantly more remyelination activity than existing remyelination agents.

Overview of multiple sclerosis

According to the National Multiple Sclerosis Society, nearly one million people in the United States are living with

MS. The symptoms of MS include numbness or tingling, weakness, dizziness and vertigo, spasticity, vision problems, sexual
problems, bladder or bowel problems, pain, cognitive changes, emotional changes, and depression. Most MS is initially
relapsing-remitting MS in which patients experience periods of new or relapsing symptoms followed by recovery and periods
of remission. Early in the disease course, the patients are able to remyelinate the demyelinated nerves at least in part. As the
disease progresses the ability of the body to remyelinate axons significantly decreases. This leads to progressive and
irreversible neurological deficits.

The FDA has approved a number of disease-modifying therapies for MS that reduce the immune system attack on

myelin, which may reduce the number of relapses, delay progression of disability, and limit new disease activity. However,
none of these products repair the central nervous system or lead to remyelination of the nerve fibers, and there is no cure for
MS. There are no FDA approved remyelinating therapies for MS. Our program aims to induce OPCs to become functional
myelinating oligodendrocytes leading to myelin repair.

Leveraging our PCA platform for future applications

In addition to our hearing and MS programs, we believe our PCA platform has the potential to address a wide range of

clinical applications. In directing our internal research, research collaborations, and in-licensing efforts, we intend to target
areas of high unmet medical need for which the underlying disease process involves loss or degeneration of key cells that
could be reversed using PCA. We believe the PCA platform could further be applied to diseases of the muscle,
gastrointestinal tract, skin, and bone. We intend to continue to identify areas with high unmet need where our PCA platform
and novel approach to regenerative medicine could lead to potentially disease-modifying therapeutics that create healthy
functional tissues and improve patients’ lives.

Manufacturing

Our product candidates consist of small chemical compounds to stimulate cell and tissue regeneration in vivo. As a

result, we can rely on the well-established and available manufacturing and drug-delivery technologies developed over
decades by the pharmaceutical industry. We source our active pharmaceutical ingredients from contract manufacturers with a
track record of FDA-compliant manufacturing. After rigorous internal and external quality control testing, we release these
materials to additional contract manufacturers for formulation and packaging into final drug product for use in clinical
testing. We expect to use a similar hybrid of internal and contract resources for commercialization of our products, at least
until our operations reach a scale sufficient to justify investment in internal manufacturing capacity.

22

Commercialization

We intend to directly market and commercialize our lead product candidate, FX-322 for the treatment of SNHL, if
approved in the United States, by developing our own sales and marketing force, targeting ENTs and audiologists. Under the
Astellas Agreement, Astellas has the right to market and commercialize FX-322 for the treatment of SNHL, and any other
products containing both a GSK-3 inhibitor and an HDAC inhibitor if approved, outside of the United States. For any other
product candidates that are not part of the Astellas Agreement and that may be approved, we intend to establish marketing
and commercialization strategies for each as we approach potential approval and expect to be able to leverage our then-
existing sales and marketing force.

Intellectual property

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

important to the development of our business, including by seeking, maintaining, and defending patent rights, whether
developed internally or licensed from third parties. We also rely on trade secrets, know-how, continuing technological
innovation, and in-licensing opportunities to develop, strengthen, and maintain our proprietary position in our field.

Our future commercial success depends, in part, on our ability to: obtain and maintain patent and other proprietary
protection for commercially important technology, inventions, and know-how related to our business; defend and enforce our
intellectual property rights, in particular our patent rights; preserve the confidentiality of our trade secrets; and operate
without infringing, misappropriating, or violating the valid and enforceable patents and proprietary rights of third parties. Our
ability to stop third parties from making, using, selling, offering to sell, or importing products identical or similar to ours may
depend on the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities.

The patent positions of biotechnology and pharmaceutical companies like ours are generally uncertain and can involve
complex legal, scientific, and factual issues. We cannot predict whether the patent applications we are currently pursuing will
issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient proprietary
protection from competitors. We also cannot ensure that patents will issue with respect to any patent applications that we or
our licensors may file in the future, nor can we ensure that any of our owned or licensed patents or future patents will be
commercially useful in protecting our product candidates and methods of manufacturing the same. In addition, the coverage
claimed in a patent application may be significantly reduced before a patent is issued, and its scope can be reinterpreted and
even challenged after issuance. As a result, we cannot guarantee that any of our products will be protected or remain
protectable by enforceable patents. Moreover, any patents that we hold may be challenged, circumvented, or invalidated by
third parties. See “Risk factors—Risks related to our intellectual property” for a more comprehensive description of risks
related to our intellectual property.

In an effort to secure our intellectual property positions we generally file patent applications directed to our programs.
As of March 19, 2021, we owned, licensed, or have an option to license 38 patent families. These patent families include 6
pending Patent Cooperation Treaty (PCT) applications, 22 U.S. patents, 35 ex-U.S. patents, 83 pending ex-U.S. patent
applications, and 27 pending U.S. utility applications.

The intellectual property portfolio for our lead programs as of February 28, 2021, are summarized below. Prosecution

is a lengthy process, during which the scope of the claims initially submitted for examination by the U.S. Patent and
Trademark Office may be significantly narrowed before issuance, if issued at all. We expect this may be the case with respect
to some of our pending patent applications referred to below.

23

Hearing loss

The patent portfolio for our Hearing Loss program is based upon our owned and in-licensed patent families that include

patents and patent applications directed generally to compositions of matter, pharmaceutical compositions, and methods of
using the same to treat hearing loss; and specifically directed to compositions of matter of our lead product FX-322,
pharmaceutical compositions of FX-322 and methods of using the same to treat hearing loss. The in-licensed patents and
patent applications are subject to license agreements with Massachusetts Institute of Technology and Massachusetts Eye and
Ear Infirmary described herein. As of March 19, 2021, we have rights to, through ownership and in-licensing, 31 patent
families, including 17 U.S. patents, 32 ex-U.S. patents, 21 pending U.S. utility patent applications, 65 pending ex-U.S. patent
applications, and 5 pending PCT applications relate to treating hearing loss, both generally and related to FX-322. While we
believe that the specific and generic claims contained in our issued U.S. patents provide protection for the composition of
matter and the method of using FX-322 to treat hearing loss and/or diseases associated with the absence or lack of certain
tissue cells, third parties may nevertheless challenge such claims in our patents. If any such claims are invalidated or rendered
unenforceable for any reason, we will lose valuable intellectual property rights, and our ability to prevent others from
competing with us would be impaired. Any U.S. or ex-U.S. patents that may issue from pending applications that we control,
if any, for our hearing program, including our lead product FX-322, are projected to have a statutory expiration date in
between 2035 and 2040, excluding any additional term for patent term adjustments or patent term extensions, if applicable.

Multiple sclerosis program

We plan to use a similar intellectual property strategy when building protection with respect to other programs. Within

our MS program, we advise on a portfolio of intellectual property directed to the treatment of MS, through ownership and
exclusive in-licensing from Scripps and Cambridge Enterprise. As of March 19, 2021, no development candidate has been
designated, but the intellectual property portfolio for our MS research program currently includes 4 patent families including
3 U.S. patents, 3 ex-U.S. patents, 4 pending U.S. utility patent applications, and 11 ex-U.S. patent applications. While we
believe that the specific and generic claims, contained in our U.S. and ex-U.S. patents provide protection for the claimed
pharmaceutical compositions and methods of use third parties may nevertheless challenge such claims. If any such claims are
invalidated or rendered unenforceable for any reason, we will lose valuable intellectual property rights, and our ability to
prevent others from competing with us would be impaired. Any U.S. or ex-U.S. patents that may issue from pending
applications that we control, if any, for our MS are projected to have a statutory expiration date between 2032 and 2039,
excluding any additional term for patent term adjustments or patent term extensions. The term of individual patents depends
upon the legal term of the patents in the countries in which they are obtained. In most countries in which we file, the patent
term is 20 years from the earliest date of filing a non-provisional patent application.

In the United States, the term of a patent covering an FDA-approved drug may, in certain cases, be eligible for a patent

term extension under the Hatch-Waxman Act as compensation for the loss of patent term during the FDA regulatory review
process. The period of extension may be up to five years, but cannot extend the remaining term of a patent beyond a total of
14 years from the date of product approval. Only one patent among those eligible for an extension and only those claims
covering the approved drug, a method for using it, or a method for manufacturing it may be extended. Similar provisions are
available in Europe and in certain other jurisdictions to extend the term of a patent that covers an approved drug. It is possible
that issued U.S. patents covering the use of products from our intellectual property may be entitled to patent term extensions.
If our use of drug candidates or the drug candidate itself receive FDA approval, we intend to apply for patent term
extensions, if available, to extend the term of patents that cover the approved use or drug candidate. We also intend to seek
patent term extensions in any jurisdictions where available, however, there is no guarantee that the applicable authorities,
including the FDA, will agree with our assessment of whether such extensions should be granted, and, even if granted, the
length of such extensions.

In addition to patent protection, we rely upon unpatented trade secrets and confidential know-how and continuing

technological innovation to develop and maintain our competitive position. However, trade secrets and confidential know-
how are difficult to protect. We seek to protect our proprietary information, in part, using confidentiality agreements with any
collaborators, scientific advisors, employees and consultants and invention assignment agreements with our employees. We
also have agreements requiring assignment of inventions with selected consultants, scientific advisors, and collaborators.
These agreements may not provide meaningful protection. These agreements may also be breached, and we may not have an
adequate remedy for any such breach. In addition, our trade secrets and/or confidential know-how may become known or be
independently developed by a third party, or misused by any collaborator to whom we disclose such information. Despite any
measures taken to protect our intellectual property, unauthorized parties may attempt to copy aspects of our products or
obtain or use information that we regard as proprietary. Although we take steps to protect our proprietary information, third
parties may independently develop the same or similar proprietary information or may otherwise gain access to our
proprietary information. As a result, we may be unable to meaningfully protect our trade secrets and proprietary information.

Our commercial success will also depend in part on not infringing upon the proprietary rights of third parties. It is
uncertain whether the issuance of any third-party patent would require us to alter our development or commercial strategies,

24

or our drugs or processes, obtain licenses, or cease certain activities. Our breach of any license agreements or failure to obtain
a license to proprietary rights that we may require to develop or commercialize our future drugs may have an adverse impact
on us. If third parties have prepared and filed patent applications prior to March 16, 2013, in the United States that also claim
technology to which we have rights, we may have to participate in interference proceedings in the United States Patent and
Trademark Office, or USPTO, to determine priority of inventions. See “Risk factors—Risks related to our intellectual
property” for a more comprehensive description of risks related to our intellectual property.

License and collaboration agreements

Astellas Pharma Inc.

In July 2019, we entered into the Astellas Agreement with Astellas, under which we granted Astellas an exclusive,

royalty-bearing, sub-licensable, nontransferable license to certain patent rights to research, develop, manufacture, have
manufactured, use, seek and secure regulatory approval for, commercialize, offer for sale, sell, have sold and import, and
otherwise exploit licensed products containing both a GSK-3 inhibitor and an HDAC inhibitor, or the Astellas licensed
products, including our product candidate FX-322, outside of the United States. We also granted Astellas a right of first
negotiation and a right of last refusal if we enter into any negotiation or agreement of any kind (other than an acquisition of
all of our stock or assets) with any third party under which such third party would obtain the right to develop, manufacture, or
commercialize Astellas licensed products in the United States.

We and Astellas have agreed to jointly develop the Astellas licensed products, including potentially carrying out joint
studies. Each party has agreed to use commercially reasonable efforts to carry out development activities assigned to it under
an agreed-upon development plan. Astellas has agreed to use commercially reasonable efforts to obtain regulatory approval
for at least one Astellas licensed product in SNHL and in age-related hearing loss, in each case, in one major Asian country
and one major European country. We have agreed to use commercially reasonable efforts to obtain regulatory approval for at
least one Astellas licensed product in the United States. Astellas has the sole right to commercialize the Astellas licensed
products outside of the United States, and we have the sole right to commercialize the Astellas licensed products in the
United States. Astellas has agreed to use commercially reasonable efforts to commercialize Astellas licensed products in a
major Asian country and a major European country following receipt of regulatory approval in such countries.

As consideration for the licensed rights under the Astellas agreement, Astellas paid us an upfront payment of $80.0

million in July 2019 and has agreed to pay potential development milestone payments up to $230.0 million. Specifically, we
would receive development milestone payments of $65.0 million and $25.0 million upon the first dosing of a patient in a
Phase 2b clinical trial for SNHL in Europe and Asia, respectively, and $100.0 million and $40.0 million upon the first dosing
of a patient in a Phase 3 clinical trial for SNHL in Europe and Asia, respectively. If the Astellas licensed products are
successfully commercialized, we would be eligible for up to $315.0 million in potential commercial milestone payments and
also tiered royalties at rates ranging from low- to mid-teen percentages.

The Astellas Agreement remains in effect until the expiration of all royalty obligations. Royalties are paid on a licensed

product-by-licensed product and country-by-country basis until the latest of (i) the expiration of the last valid claim in the
licensed patent rights with respect to such Astellas licensed product in such country or (ii) a set number of years from the first
commercial sale of such Astellas licensed product in such country. Astellas may terminate the Astellas Agreement at will
upon 60 days’ written notice. Each party has the right to terminate the Astellas Agreement due to the other party’s material
breach if such breach remains uncured for 90 days (or 45 days in the case of nonpayment) or if the other party becomes
bankrupt.

Massachusetts Institute of Technology

In December 2016, we entered into an Exclusive Patent License Agreement, or the MIT License, with the

Massachusetts Institute of Technology, or MIT, under which we received an exclusive, worldwide, royalty-bearing license to
certain patent rights to develop, make, have made, use, sell, offer to sell, lease, and import products, or the MIT licensed
products, and to develop and perform processes, or the MIT licensed processes, which incorporate the licensed technology
for the treatment of disease, including, but not limited to, the prevention and remediation of hearing loss. We also have the
right to grant sublicenses under the MIT License. MIT and Brigham and Women’s Hospital retain the right on behalf of
themselves and all other nonprofit research institutions to practice the licensed patent rights for nonclinical research,
teaching, and educational purposes.

We are required to use diligent efforts to develop and commercialize the MIT licensed products or processes and to

make such products or processes reasonably available to the public. We are also subject to certain development obligations
with regards to a first MIT licensed product. We have satisfied certain obligations related to preclinical and clinical studies
and the filing of an IND for a first MIT licensed product with our development activities related to FX-322. Our future

25

development obligations are: (i) to commence a Phase III clinical trial for such product within five years of the IND filing for
such product, (ii) to file a New Drug Application, or NDA, or equivalent with the FDA or comparable European regulatory
agency for such product within nine years of the IND filing for such product, and (iii) to make a first commercial sale of such
product within 11 years of the IND filing for such product. We also have certain development obligations with regards to a
second MIT licensed product. If we fail to meet our development obligations, other than those relating to a second MIT
licensed product, MIT may terminate the MIT License. In the event that we have failed to fulfill our development timeline
obligation with respect to a second MIT licensed product and fail to cure such breach within 90 days of written notice by
MIT, MIT may restrict the licensed field to the prevention and remediation of hearing loss in humans and animals. We do not
have the right to control prosecution of the in-licensed patent applications, and our rights to enforce the in-licensed patents
are subject to certain limitations.

Upon entering the MIT License, we paid a $50 thousand license fee payment and issued to MIT shares of our common

stock equal to 5% of our then-outstanding capital stock. We are required to pay certain annual license maintenance fees
ranging from $30 thousand to $0.1 million per year prior to first commercial sale of a MIT licensed product and an annual
license maintenance fee of $0.2 million every year afterwards, which may be credited to running royalties during the same
calendar year, if any. We are also required to make potential milestone payments in an aggregate amount of up to
$2.9 million on each MIT licensed product or process. In addition, we agreed to pay a low single-digit royalty on the MIT
licensed products and processes and a 20% royalty on sub-license revenues. In 2019, we paid MIT $16.0 million dollars
representing the royalty on the upfront payment received from Astellas.

The MIT License will remain in effect until the expiration or abandonment of all licensed issued patents and filed
patent applications, unless terminated earlier. We have the right to terminate for any reason upon three months’ prior written
notice. MIT has the right to terminate immediately if we cease to carry on any business related to the MIT License. MIT may
also terminate the MIT License for our material breach if such breach remains uncured for 90 days (or 30 days in the case of
nonpayment). MIT may also terminate the MIT License if we or our affiliates commence any action against MIT to declare
or render any claim of the licensed patent rights invalid, unpatentable, unenforceable, or not infringed, or if our sub-licensee
commences such actions and we do not terminate such sub-license within 30 days after MIT’s demand. MIT has the right to
increase all payments due by us, instead of terminating the MIT License in the case of a patent challenge.

In May 2019, the MIT License was amended to update the diligence milestones for a second MIT licensed product.

Massachusetts Eye and Ear (Formerly Massachusetts Eye and Ear Infirmary)

In February 2019, we entered into an Non-Exclusive Patent License Agreement, or the MEE License, with the
Massachusetts Eye and Ear, or MEE, under which we received a non-exclusive, non-sub-licensable, worldwide, royalty-
bearing license to certain patent rights to develop, make, have made, use, sell, offer to sell, lease and import products and to
develop and perform processes that incorporate the licensed technology for the treatment or prevention of hearing loss, or the
MEE licensed products. We are obligated to use diligent efforts to develop and commercialize the MEE licensed products.
We met one of our milestone timeline obligations by dosing a first patient in a Phase II trial by December 31, 2020. We are
still subject to a milestone timeline obligation to dose a first patient in a Phase III trial by December 31, 2024. We do not
control the filing, prosecution, enforcement, and defense of any licensed patent rights.

Upon entering the MEE License, we made a $20 thousand license fee payment. We are obligated to pay certain annual

license maintenance fees between $5 thousand and $7.5 thousand per each MEE patent family case number included in the
licensed MEE patent rights prior to first commercial sale of an MEE licensed product. We are also obligated to pay a
minimum annual royalty payment of $15 thousand per each MEE patent family case number included in the licensed MEE
patent rights after first commercial sale of an MEE licensed product. We are also obligated to make milestone payments up to
$350 thousand on each product or process that incorporates the licensed patent rights. In addition, we have agreed to pay a
low single-digit royalty on products and processes that incorporate the licensed patent rights.

The MEE License remains in effect until all issued patents and filed patent applications within the licensed patent
rights have expired or been abandoned, unless terminated earlier. We have the right to terminate the MEE License at will by
30 business days’ advance written notice to MEE. MEE has the right to terminate the MEE License (i) if we fail to make any
payment due within 30 business days after MEE notifies us of such failure, (ii) if we fail to maintain required insurance,
(iii) upon 45 business days’ written notice if we become insolvent, or (iv) for any other default by us that is not cured within
60 business days of receipt of written notice. MEE also has the right to terminate if we or our affiliates challenge the validity
of the licensed patent rights.

The Scripps Research Institute (California Institute for Biomedical Research)

In September 2018, we entered into a license agreement, or the CALIBR License, with the California Institute for
Biomedical Research, or CALIBR, a division of Scripps, under which we received an exclusive, worldwide, royalty-bearing
license to certain patent rights to make, have made, use, sell, offer to sell, and import products, or the CALIBR licensed
products, which incorporate licensed technology for the treatment of MS. We also have the right to grant sublicenses under
the CALIBR License. CALIBR reserves the right to use for itself and the right to grant nonexclusive licenses to other
nonprofit or academic institutions for any internal research and educational purposes.

We have agreed to use commercially reasonable efforts to develop, manufacture, and sell at least one CALIBR licensed
product. We are also subject to certain milestone timeline obligations, which may be extended in certain circumstances as set
forth in the CALIBR License to: (i) submit an IND (or equivalent) for a CALIBR licensed product by the 30th month after
the effective date of the CALIBR License, (ii) initiate a Phase II clinical trial (or equivalent) for a CALIBR licensed product
by the fourth anniversary of the effective date of the CALIBR License, and (iii) initiate a Phase III clinical trial (or
equivalent) for a CALIBR licensed product by the sixth anniversary of the effective date of the CALIBR License. We do not
have the right to control prosecution of the in-licensed patent applications, and our rights to enforce the in-licensed patents
are subject to certain limitations.

Upon entering the CALIBR license, we made a $1.0 million license fee payment, and are required to make milestone
payments in an aggregate amount of up to $26.0 million for each category of CALIBR licensed products. Category 1 is any
CALIBR licensed products containing a compound that modulates any muscarinic receptor, and Category 2 is any CALIBR
licensed products not included in Category 1 that could differentiate oligodendrocyte precursor cells from in vitro studies
and/or are active in animal models relevant to MS. We are also required to pay a mid-single-digit royalty on CALIBR
licensed products and a royalty on sub-license revenues ranging from a low-teen percentage to 50%.

The CALIBR License continues in effect until expiration of all our obligations to pay royalties. Royalties are payable

by us on a country-by-country and licensed-product-by-licensed product basis upon the later of (i) the expiration or
abandonment of all valid claims of the licensed patent rights in such country and (ii) 10 years from the first commercial sale
of each CALIBR licensed product in such country. We may terminate the CALIBR License at will upon 30 days’ prior
written notice. We may also elect to terminate our license to one or more licensed patents in any or all jurisdictions by giving
90 days’ prior written notice to CALIBR. CALIBR may terminate the CALIBR License for our material breach if such
breach remains uncured for 30 days. CALIBR has the right to terminate or reduce the license to a non-exclusive license if we
fail to use diligent efforts to develop and commercially exploit CALIBR licensed products.

The Scripps Research Institute

In September 2018, we entered into a Research Funding and Option Agreement, or the Scripps option agreement, with

Scripps, under which we were granted an exclusive option to acquire an exclusive, sublicensable, worldwide license under
certain intellectual property related to the treatment of MS. If we exercise such option, the CALIBR License shall be
amended to include such intellectual property.

As consideration for the Scripps option agreement, we are required to make funding payments totaling $0.7 million to

Scripps to support its research activities. Scripps has agreed to use reasonable efforts to perform the research program
pursuant to the Scripps option agreement. The Scripps option agreement had a one-year term and was renewed for a second
year by mutual written agreement.

In September 2020, we extended the term of the Scripps option agreement through the end of December 2021. As
consideration for this extension, we are required to make additional funding payments of $0.6 million to Scripps through
December 2021. We have the right to terminate by giving 90 days’ advance written notice. Scripps has the right to terminate
in the event of nonpayment by us that remains uncured for 10 days. Each party has the right to terminate in the event of the
other party’s material breach that remains uncured for 60 days or if the other party becomes bankrupt.

Cambridge Enterprise Limited

In December 2019, we entered into an Exclusive Patent License Agreement, or the Cambridge License, with

Cambridge, under which we received an exclusive, worldwide, royalty-bearing license to certain patent rights to make, have
made, use, sell, offer to sell, and import products, or the Cambridge licensed products, which incorporate licensed technology
for the treatment of demyelinating diseases. We also have the right to grant sublicenses under the Cambridge License.

27

Cambridge reserves the right to use for itself (as well as for the inventors and the funder) and the right to grant nonexclusive
licenses to other academic institutions for any academic publication, research and teaching and clinical patient care.

We have agreed to use diligent and good faith efforts to develop and commercially exploit at least one Cambridge

licensed product. Upon entering into the Cambridge License, we made a $50.0 thousand license fee payment. We are
obligated to pay an annual license fee of $50.0 thousand. We are also obligated to make milestone payments up to $10.5
million on each Cambridge licensed product. In addition, we have agreed to pay a low single-digit royalty on products that
incorporate the licensed patent rights, subject to offset in certain circumstances.

The Cambridge License continues in effect on a country-by-country basis until the expiration or revocation, without

right of further appeal, of all licensed issued patents and filed patent applications, unless terminated earlier. We have the right
to terminate for any reason upon 90 days’ prior written notice. Each party has the right to terminate immediately if the other
party ceases to carry on its business. Either party may also terminate the Cambridge License for material breach if such
breach remains uncured for 30 days. Cambridge may also terminate the Cambridge License if we fail to diligently develop
and commercially exploit at least one Cambridge licensed product or we or our affiliates or sub-licensees commence any
action against Cambridge to declare or render any claim of the licensed patent rights invalid, unpatentable, unenforceable, or
not infringed.

Competition

As a clinical-stage biotechnology company, we face competition from a wide array of companies in the

pharmaceutical, biotechnology, and medical device industries. These include both small companies and large companies with
much greater financial and technical resources and far longer operating histories than our own. We also compete with the
intellectual property, technology, and product development efforts of academic, governmental, and private research
institutions.

Our competitors may have significantly greater financial resources, established presence in the market, expertise in
research and development, manufacturing, preclinical and clinical testing, obtaining regulatory approvals and reimbursement,
and marketing approved products than we do. These competitors also compete with us in recruiting and retaining qualified
scientific, sales, marketing, and management personnel, establishing clinical trial sites and patient registration for clinical
trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Smaller or early-stage
companies may also prove to be significant competitors, particularly through collaborative arrangements with large and
established companies.

The key competitive factors affecting the success of any product candidates that we develop, if approved, are likely to

be their efficacy, safety, convenience, price, and the availability of reimbursement from government and other third-party
payors. Our commercial opportunity for any of our product candidates could be reduced or eliminated if our competitors
develop and commercialize products that are more effective, have fewer or less severe side effects, are more convenient, or
are less expensive than any products that we may develop. Our competitors also may obtain FDA or other regulatory
approval for their products more rapidly than we may obtain approval for ours and may commercialize products more quickly
than we are able to.

We are aware of the following treatment options in the areas that we are initially targeting:

Hearing loss

There are dozens of hearing aid brands, although approximately 80% of these devices are manufactured by four leading

companies. There are three manufacturers of cochlear implants that market in the United States. We are also aware of
multiple companies developing therapeutics to treat various forms of hearing loss. There are two companies with potential
therapies to regenerate hair cells currently in clinical trials. Novartis conducted a Phase 1/2 trial with intracochlear delivery of
an adenovirus-based gene therapy in subjects with severe to profound hearing loss, the data from which has not been shared
to date, and Audion Therapeutics is conducting a Phase 2 study of its notch inhibitor, LY3056480, and Pipeline Therapeutics
is conducting a Phase 1/2 study of its gamma secretase inhibitor. In 2020 Otonomy, Inc. disclosed top level data from a Phase
1/2 study of OTO-413, a sustained-exposure formulation of brain-derived neurotrophic factor, in subjects with a condition
described as speech-in-noise impairment. In addition, Sensorion, a clinical stage company is conducting a Phase 2 study to
treat sudden SNHL. There are also multiple programs in early-stage or preclinical development by pharmaceutical and
biotechnology companies. In addition, there are several companies with programs to regrow neurons in the cochlea to treat
hearing loss, and companies developing otoprotective therapies, which are intended to reduce damage to hair cells.

28

Multiple sclerosis

There are multiple therapeutic options for treating the symptoms of MS, as well as the underlying disease. However, all

approved therapies are directed at blocking demyelination, and, to our knowledge, there are no approved therapies which
promote remyelination. We are aware of numerous efforts to identify drugs or biologics that can stimulate oligodendrocyte
regeneration and myelin repair in the central nervous system. These include Acorda Therapeutics which has conducted two
Phase 1 trials of its monoclonal antibody rHIgM22 in MS patients. Convelo Therapeutics is developing potential
remyelinating compounds that inhibit enzymes in the brain involved in the production of cholesterol for which they planned
to begin clinical trials in 2019, while Pipeline Therapeutics is developing a selective M1 receptor antagonist to treat multiple
sclerosis and other demyelinating disorders. This is an active research area with a number of entities researching compounds,
antibodies, and protein which may enhance remyelination.

Government regulation

The FDA and comparable regulatory authorities in state and local jurisdictions and in other countries impose

substantial and burdensome requirements upon companies involved in the clinical development, manufacture, marketing, and
distribution of drugs, such as those we are developing. These agencies and other federal, state, and local entities regulate,
among other things, the research and development, testing, manufacture, quality control, safety, effectiveness, labeling,
storage, record keeping, approval, advertising and promotion, distribution, post-approval monitoring and reporting, sampling,
and export and import of our product candidates.

U.S. drug development process

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

implementing regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate
federal, state, local, and foreign statutes and regulations requires 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 a variety of administrative or judicial sanctions, such as the FDA’s
refusal to approve pending NDAs, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters,
product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of
government contracts, restitution, disgorgement, or civil or criminal penalties.

The process required by the FDA before a drug may be marketed in the United States generally involves the following:

•

•

•

•

•

•

•

•

•

•

completion of preclinical laboratory tests and formulation studies, as well as animal safety studies, in compliance
with the FDA’s good laboratory practice, or GLP, regulations, as appropriate;

submission to the FDA of an IND which must become effective before human clinical trials may begin;

approval by an independent institutional review board, or IRB, at each clinical site before each trial may be
initiated;

performance of adequate and well-controlled human clinical trials in accordance with good clinical practice, or
GCP, requirements to establish the safety and efficacy of the proposed drug product for each indication;

submission to the FDA of an NDA;

endorsement by an FDA advisory committee, if applicable;

satisfactory completion of an FDA inspection of the clinical site(s), and related services involved in the conduct
of the clinical studies to assess compliance with good clinical practices, or GCP;

satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product is
produced to assess compliance with current good manufacturing practice, or cGMP, requirements, and to assure
that the facilities, methods, and controls are adequate to preserve the drug’s identity, strength, quality, and purity;

FDA review and approval of the NDA prior to commercial marketing or sale of the drug in the United States; and

compliance with any post-approval requirements, including the potential requirement to implement a Risk
Evaluation and Mitigation Strategy, or REMS, or to conduct a post-approval study or studies.

29

Preclinical studies

Preclinical studies include laboratory evaluation of product chemistry, toxicity, and formulation, as well as animal

studies to assess potential safety and efficacy. An IND sponsor must submit the results of the preclinical tests, together with
manufacturing information, analytical data, and any available clinical data or literature, among other things, to the FDA as
part of an IND. Some preclinical testing may continue even after the IND is submitted. An IND automatically becomes
effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to the
submission including to one or more proposed clinical trials and places the clinical trial on a partial or full clinical hold. In
such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Clinical
holds also may be imposed by the FDA at any time before or during clinical trials due to safety concerns about on-going or
proposed clinical trials or noncompliance with specific FDA requirements, and the trials may not begin or continue until the
FDA notifies the sponsor that the hold has been lifted. As a result, submission of an IND may not result in the FDA allowing
clinical trials to commence.

Clinical trials

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

qualified investigators in accordance with GCP requirements, which include the requirement that all research subjects
provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols
detailing, among other things, the objectives of the trial, the parameters to be used in monitoring safety, and the effectiveness
criteria to be evaluated. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to the
FDA as part of the IND. In addition, an IRB at each institution participating in the clinical trial must review and approve the
plan for any clinical trial before it commences at that institution. Information about certain clinical trials must be submitted
within specific time frames to the National Institutes of Health, or NIH, for public dissemination on their
www.clinicaltrials.gov website.

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

•

•

•

Phase 1: The drug is initially introduced into healthy human subjects or patients with the target disease or
condition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion, and, if possible,
to gain an early indication of its effectiveness.

Phase 2: The drug is administered to a limited patient population to identify possible adverse effects and safety
risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases, and to determine dosage
tolerance and optimal dosage.

Phase 3: The drug is administered to an expanded patient population, generally at geographically dispersed
clinical trial sites, in well-controlled clinical trials to generate enough data to statistically evaluate the efficacy
and safety of the product for approval, to establish the overall risk-benefit profile of the product, and to provide
adequate information for the labeling of the product.

The FDA or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the

research subjects or patients are being exposed to an unreasonable health risk. Similarly, an IRB can suspend or terminate
approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s
requirements or if the drug has been associated with unexpected serious harm to patients. In addition, some clinical trials are
overseen by an independent group of qualified experts organized by the sponsor, known as a data safety monitoring board or
committee. Depending on its charter, this group may determine whether a trial may move forward at designated check points
based on access to certain data from the trial.

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

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA, and more
frequently if serious adverse events occur. Phase 1, Phase 2, and Phase 3 clinical trials may not be completed successfully
within any specified period, or at all. There are also requirements governing the registration of, reporting of ongoing clinical
trials and completed trial results to public registries.

30

Marketing approval

Assuming successful completion of the required clinical testing, the results of the preclinical and clinical studies,
together with detailed information relating to the product’s chemistry, manufacture, controls, and proposed labeling, among
other things, are submitted to the FDA as part of an NDA requesting approval to market the product for one or more
indications. In most cases, the submission of an NDA is subject to a substantial application user fee. Under the Prescription
Drug User Fee Act, or PDUFA, guidelines that are currently in effect, the FDA has a goal of ten months from the date of
“filing” of a standard NDA for a new molecular entity to review and act on the submission. This review typically takes
12 months from the date the NDA is submitted to the FDA because the FDA has approximately two months to make a
“filing” decision. Specifically, the FDA conducts a preliminary review of all NDAs within the first 60 days after submission,
before accepting them for filing, to determine whether they are sufficiently complete to permit substantive review. The FDA
may request additional information rather than accept an NDA for filing. In this event, the application must be resubmitted
with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing.
Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA reviews an NDA to
determine, among other things, whether the submitted information supports that the drug is safe and effective and whether the
facility in which it is manufactured, processed, packaged, or held meets standards designed to assure the product’s continued
safety, quality, and purity.

The FDA also may require submission of a REMS plan to ensure that for certain medications with serious safety

concerns the benefits of the drug outweigh its risks. The REMS plan could include medication guides, physician
communication plans, assessment plans, and/or elements to assure safe use, such as restricted distribution methods, patient
registries, or other risk minimization tools.

The FDA may refer an application for a novel drug to an advisory committee. An advisory committee is a panel of
independent experts, including clinicians and other scientific experts, that reviews, evaluates, and provides a recommendation
as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations
of an advisory committee, but it considers such recommendations carefully when making decisions.

Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is manufactured.

The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in
compliance with cGMP requirements and adequate to assure consistent production of the product within required
specifications. Additionally, before approving an NDA, the FDA may inspect one or more clinical trial sites to assure
compliance with GCP requirements.

After evaluating the NDA and all related information, including the advisory committee recommendation, if any, and
inspection reports regarding the manufacturing facilities and clinical trial sites, the FDA may issue an approval letter, or, in
some cases, a Complete Response Letter, or CRL. A CRL generally contains a statement of specific conditions that must be
met in order to secure final approval of the NDA and may require additional clinical or preclinical testing in order for the
FDA to reconsider the application for approval. Even with submission of this additional information, the FDA ultimately may
decide that the application does not satisfy the regulatory criteria for approval. If and when those conditions have been met to
the FDA’s satisfaction, the FDA will typically issue an approval letter. An approval letter authorizes commercial marketing
of the drug with specific prescribing information for specific indications.

Even if the FDA approves a product, it may limit the approved indications for use of the product, require that
contraindications, warnings, or precautions be included in the product labeling, require that post-approval studies, including
Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs
to monitor the product after commercialization, or impose other conditions, including distribution and use restrictions or
other risk management mechanisms under a REMS, which can materially affect the potential market and profitability of the
product. The FDA may prevent or limit further marketing of a product based on the results of post-marketing studies or
surveillance programs. After approval, some types of changes to the approved product, such as adding new indications,
manufacturing changes, and additional labeling claims, are subject to further testing requirements and FDA review and
approval.

The Pediatric Research Equity Act, or PREA, requires a sponsor to conduct pediatric clinical trials for most drugs, for a

new active ingredient, new indication, new dosage form, new dosing regimen, or new route of administration. Under PREA,
original NDAs and supplements must contain a pediatric assessment unless the sponsor has received a deferral or waiver, or
the indication sought is for an orphan condition. The required assessment must evaluate the safety and effectiveness of the
product for the claimed indications in all relevant pediatric subpopulations and support dosing and administration for each
pediatric subpopulation for which the product is safe and effective. The sponsor or the FDA may request a deferral of
pediatric clinical trials for some or all of the pediatric subpopulations. A deferral may be granted for several reasons,
including a finding that the drug is ready for approval for use in adults before pediatric clinical trials are complete or that
additional safety or effectiveness data needs to be collected before the pediatric clinical trials begin. The FDA must send a

31

noncompliance letter to any sponsor that fails to submit the required assessment, keep a deferral current, or fails to submit a
request for approval of a pediatric formulation. In some situations, the requirement for studies in pediatric populations can be
waived if there is no relevant use.

FDA-expedited development and review programs

The FDA has various programs, including orphan drug designation, rare pediatric disease designation, fast track
designation, accelerated approval priority review, and breakthrough therapy designation, which are intended to expedite or
simplify the process for the development and the FDA review of drugs that are intended for the treatment of serious or life-
threatening diseases or conditions and demonstrate the potential to address unmet medical needs. The purpose of these
programs is to provide important new drugs to patients earlier than under standard FDA review procedures.

To be eligible for a fast track designation, the FDA must determine, based on the request of a sponsor, that a product is

intended to treat a serious or life-threatening disease or condition, demonstrates the potential to address an unmet medical
need, and is actively developing the drug for the disease. The FDA will determine that a product will fill an unmet medical
need if it will provide a therapy where none exists or provide a therapy that may be potentially superior to existing therapy
based on efficacy or safety factors. The FDA may review sections of the NDA for a fast track product on a rolling basis
before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the
NDA, the FDA agrees to accept sections of the NDA and determines that the schedule is acceptable, and the sponsor pays
any required user fees upon submission of the first section of the NDA.

The FDA may give a priority review designation to drugs that offer major advances in treatment or provide a treatment

where no adequate therapy exists. A priority review means that the goal for the FDA to review an application is six months,
rather than the standard review of 10 months under current PDUFA guidelines. Under the new PDUFA agreement, these six-
and 10-month review periods are measured from the “filing” date rather than the receipt date for NDAs for new molecular
entities, which typically adds approximately two months to the timeline for review and decision from the date of submission.
Most products that are eligible for fast track designation are also likely to be considered appropriate to receive a priority
review, and, if relevant, accelerated approval.

In addition, products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that

provide meaningful therapeutic benefit over existing treatments may be eligible for accelerated approval and may be
approved on the basis of adequate and well-controlled clinical trials establishing that the drug product has an effect on a
surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier
than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or
other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of
alternative treatments. As a condition of approval, the FDA may require a sponsor of a drug receiving accelerated approval to
perform post-marketing studies to verify and describe the predicted effect on irreversible morbidity or mortality or other
clinical endpoint, and the drug may be subject to accelerated withdrawal procedures.

Moreover, under the provisions of the Food and Drug Administration Safety and Innovation Act, or FDASIA, passed in

July 2012, a sponsor can request designation of a product candidate as a “breakthrough therapy.” A breakthrough therapy is
defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening
disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over
existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in
clinical development. Drugs designated as breakthrough therapies are also eligible for priority review and accelerated
approval. The FDA must take certain actions, such as holding timely meetings and providing advice, intended to expedite the
development and review of an application for approval of a breakthrough therapy. The designation includes all the benefits of
a fast track designation. The breakthrough therapy designation is a distinct status from both accelerated approval and priority
review, which can also be granted to the same drug if relevant criteria are met.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer

meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.
Furthermore, fast track designation, priority review, and breakthrough therapy designation do not change the standards for
approval but may expedite the development or approval process. We may explore some of these opportunities for our product
candidates as appropriate.

32

Post-approval requirements

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the

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

The FDA may impose a number of post-approval requirements as a condition of approval of an NDA. For example, the

FDA may require post-marketing testing, including Phase 4 clinical trials, and surveillance to further assess and monitor the
product’s safety and effectiveness after commercialization.

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

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

•

•

•

•

•

•

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

safety alerts, Dear Healthcare Provider letters, press releases, or other communications containing warning or
other safety information about the product;

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

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

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

injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising, and promotion of products that are placed on the market.
Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label. The
FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company
that is found to have improperly promoted off-label uses may be subject to significant liability.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act,
or PDMA, which regulates the distribution of drugs and drug samples at the federal level and sets minimum standards for the
registration and regulation of drug distributors by the states. Both the PDMA and state laws limit the distribution of
prescription pharmaceutical product samples and impose requirements to ensure accountability in distribution.

Marketing exclusivity

Market exclusivity provisions under the FDCA can delay the submission or the approval of certain marketing
applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first
applicant to obtain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not
previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the
action of the drug substance. During the exclusivity period, the FDA may not approve or even accept for review an
abbreviated new drug application, or ANDA, or an NDA submitted under Section 505(b)(2), or 505(b)(2) NDA, submitted by

33

another company for another drug based on the same active moiety, regardless of whether the drug is intended for the same
indication as the original innovative drug or for another indication, where the applicant does not own or have a legal right of
reference to all the data required for approval. However, an application may be submitted after four years if it contains a
certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder.

The FDCA alternatively provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA,

if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are
deemed by the FDA to be essential to the approval of the application. This three-year exclusivity covers only the
modification for which the drug received approval based on the new clinical investigations and does not prohibit the FDA
from approving ANDAs or 505(b)(2) NDAs for drugs containing the active agent for the original indication or condition of
use. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant
submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and
adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Pediatric exclusivity is another type of marketing exclusivity available in the United States. Pediatric exclusivity
provides for an additional six months of marketing exclusivity attached to another period of exclusivity and extends patent
life of a related patent if a sponsor conducts clinical trials in children in response to a written request from the FDA. The
issuance of a written request does not require the sponsor to undertake the described clinical trials.

Other healthcare laws and compliance requirements

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government

and by authorities in the state, local, and foreign jurisdictions in which they conduct their business. Such laws include,
without limitation, U.S. federal and state anti-kickback, fraud and abuse, false claims, consumer fraud, pricing reporting, and
transparency laws and regulations, as well as similar foreign laws in the jurisdictions outside the U.S. State laws may require
pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant
compliance guidance promulgated by the federal government, as well as require the registration of pharmaceutical sales
representatives and the reporting of pricing information and marketing expenditures. Violations of such laws, or any other
governmental regulations that apply, may result in penalties, including, without limitation, civil and criminal penalties,
damages, fines, additional reporting and oversight obligations, the curtailment or restructuring of operations, exclusion from
participation in governmental healthcare programs, and individual imprisonment.

Coverage and reimbursement

Sales of any pharmaceutical product depend, in part, on the extent to which such product will be covered by third-party

payors, such as federal, state, and foreign government healthcare programs, commercial insurance and managed healthcare
organizations, and the level of reimbursement for such product by third-party payors. Significant uncertainty exists as to the
coverage and reimbursement status of any newly approved product. Decisions regarding the extent of coverage and amount
of reimbursement to be provided are made on a plan-by-plan basis. One third-party payor’s decision to cover a product does
not ensure that other payors will also provide coverage for the product. As a result, the coverage determination process can
require manufactures to provide scientific and clinical support for the use of a product to each payor separately, and can be a
time-consuming process, with no assurance that coverage and adequate reimbursement will be applied consistently or
obtained in the first instance. For products administered under the supervision of a physician, obtaining coverage and
adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs.
Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may
not be available, which may impact physician utilization.

In addition, third-party payors are increasingly reducing reimbursements for pharmaceutical products and services. The

U.S. government and state legislatures have continued implementing cost-containment programs, including price controls,
restrictions on coverage and reimbursement, and requirements for substitution of generic products. Third-party payors are
more and more challenging the prices charged, examining the medical necessity, and reviewing the cost effectiveness of
pharmaceutical products, in addition to questioning their safety and efficacy. Adoption of price controls and cost-containment
measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit
sales of any product. Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover
a product could reduce physician usage and patient demand for the product.

In international markets, reimbursement and healthcare payment systems vary significantly by country, and many
countries have instituted price ceilings on specific products and therapies. For example, the European Union provides options
for its member states to restrict the range of medicinal products for which their national health insurance systems provide

34

reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price
for the medicinal product, or it may instead adopt a system of direct or indirect controls on the profitability of the company
placing the medicinal product on the market. Pharmaceutical products may face competition from lower-priced products in
foreign countries that have placed price controls on pharmaceutical products and may also compete with imported foreign
products. Furthermore, there is no assurance that a product will be considered medically reasonable and necessary for a
specific indication, will be considered cost-effective by third-party payors, that an adequate level of reimbursement will be
established even if coverage is available, or that the third-party payors’ reimbursement policies will not adversely affect the
ability of manufacturers to sell products profitably.

Healthcare reform

In the United States and certain foreign jurisdictions, there have been, and we expect there will continue to be, a
number of legislative and regulatory changes to the healthcare system that could affect the pharmaceutical industry. In March
2010, the ACA was signed into law, which substantially changed the way healthcare is financed by both governmental and
private insurers in the United States. The ACA contains a number of provisions of particular import to the pharmaceutical
industry, including those governing enrollment in federal healthcare programs, reimbursement adjustments, and fraud and
abuse changes. Additionally, the ACA increases the minimum level of Medicaid rebates payable by manufacturers of brand
name drugs from 15.1% to 23.1%; requires collection of rebates for drugs paid by Medicaid managed care organizations;
imposes a nondeductible annual fee on pharmaceutical manufacturers or importers who sell “branded prescription drugs” to
specified federal government programs; implements a new methodology by which rebates owed by manufacturers under the
Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted, or injected; expands of
eligibility criteria for Medicaid programs; creates a new Patient-Centered Outcomes Research Institute to oversee; identify
priorities in, and conducts comparative clinical effectiveness research, along with funding for such research; and establishes a
Center for Medicare Innovation at CMS to test innovative payment and service delivery models to lower Medicare and
Medicaid spending, potentially including prescription drug spending.

Since its enactment, there have been judicial and Congressional challenges to certain aspects of the ACA, and we
expect there will be additional challenges and amendments to the ACA in the future. For example, in December 2018, a U.S.
district court judge ruled that the ACA is unconstitutional in its entirety because the Tax Cuts and Jobs Act modified the
individual mandate. On December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the district court’s decision
that the individual mandate was unconstitutional but remanded the case back to the District Court to determine whether the
remaining provisions of the ACA are invalid as well. The U.S. Supreme Court is currently reviewing the case, although it is
unclear how the Supreme Court will rule. It is also unclear how other efforts, if any, to challenge, repeal or replace the ACA
will impact the law.

Legislative changes have been proposed and adopted since the ACA was enacted, including aggregate reductions of
Medicare payments to providers of 2% per fiscal year, which was temporarily suspended from May 1, 2020 through March
31, 2021, and reduced payments to several types of Medicare providers. Moreover, there has recently been heightened
governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in
several Congressional inquiries, and proposed and enacted legislation designed, among other things, to bring more
transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform
government program reimbursement methodologies for drug products. Individual states in the United States have also
become increasingly active in implementing regulations designed to control pharmaceutical product pricing, including price
or patient reimbursement constraints, discounts, restrictions on certain product access, and marketing cost disclosure and
transparency measures, and, in some cases, mechanisms to encourage importation from other countries and bulk purchasing.
Furthermore, there has been increased interest by third-party payors and governmental authorities in reference-pricing
systems and publication of discounts and list prices.

Foreign regulation

In addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical
trials and commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we must
obtain approval by the comparable regulatory authorities of foreign countries before we can commence clinical trials in those
countries, if relevant, and market application approval by foreign countries or economic areas, such as the European Union,
or EU, before we may market products in those countries or areas. The approval process and requirements governing the
conduct of clinical trials, product licensing, pricing, and reimbursement vary greatly from place to place, and the time may be
longer or shorter than that required for FDA approval.

In the European Economic Area, or EEA, which is comprised of the Member States of the European Union plus

Norway, Iceland and Liechtenstein, medicinal products can only be commercialized after obtaining a Marketing
Authorization, or MA. There are two types of MAs:

•

•

Community MAs—These are issued by the European Commission through the Centralized Procedure, based on
the opinion of the Committee for Medicinal Products for Human Use, or CHMP, of the European Medicines
Agency, or EMA, and are valid throughout the entire territory of the EEA. The Centralized Procedure is
mandatory for certain types of products, such as biotechnology medicinal products, orphan medicinal products,
and medicinal products indicated for the treatment of AIDS, cancer, neurodegenerative disorders, diabetes, auto-
immune, and viral diseases. The Centralized Procedure is optional for products containing a new active substance
not yet authorized in the EEA; for products that constitute a significant therapeutic, scientific or technical
innovation; or for products that are in the interest of public health in the EU.

National MAs—These are issued by the competent authorities of the Member States of the EEA and only cover
their respective territory and are available for products not falling within the mandatory scope of the Centralized
Procedure. Where a product has already been authorized for marketing in a Member State of the EEA, this
National MA can be recognized in another Member State through the Mutual Recognition Procedure. If the
product has not received a National MA in any Member State at the time of application, it can be approved
simultaneously in various Member States through the Decentralized Procedure. Under the Decentralized
Procedure, an identical dossier is submitted to the competent authorities of each of the Member States in which
the MA is sought, one of which is selected by the applicant as the Reference Member State. The competent
authority of the Reference Member State prepares a draft assessment report, a draft summary of the product
characteristics, or SmPC, and a draft of the labeling and package leaflet, which are sent to the other Member
States (referred to as the Member States Concerned) for their approval. If the Member States Concerned raise no
objections, based on a potential serious risk to public health, to the assessment, SmPC, labeling or packaging
proposed by the Reference Member State, the product is subsequently granted a National MA in all the Member
States, i.e., in the Reference Member State and the Member States Concerned.

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

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

As in the United States, it may be possible in foreign countries to obtain a period of market and/or data exclusivity that
would have the effect of postponing the entry into the marketplace of a competitor’s generic product. For example, if any of
our products receive marketing approval in the EEA, we expect they will benefit from eight years of data exclusivity and
10 years of marketing exclusivity. An additional noncumulative one-year period of marketing exclusivity is possible if during
the data exclusivity period (the first eight years of the 10-year marketing exclusivity period) we obtain an authorization for
one or more new therapeutic indications that are deemed to bring a significant clinical benefit compared to existing therapies.
The data exclusivity period begins on the date of the product’s first marketing authorization in the EEA and prevents generics
from relying on the marketing authorization holder’s pharmacological, toxicological, and clinical data for a period of eight
years. After eight years, a generic product application may be submitted, and generic companies may rely on the marketing
authorization holder’s data. However, a generic cannot launch until two years later (or a total of 10 years after the first
marketing authorization in the EU of the innovator product), or three years later (or a total of 11 years after the first
marketing authorization in the EU of the innovator product) if the marketing authorization holder obtains marketing
authorization for a new indication with significant clinical benefit within the eight-year data exclusivity period. In Japan, our
products may be eligible for eight years of data exclusivity. There can be no assurance that we will qualify for such
regulatory exclusivity, or that such exclusivity will prevent competitors from seeking approval solely on the basis of their
own studies.

36

When conducting clinical trials in the EU, we must adhere to the provisions of the European Union Clinical Trials

Directive (Directive 2001/20/EC) and the laws and regulations of the EU Member States implementing them. These
provisions require, among other things, that the prior authorization of an Ethics Committee and the competent Member State
authority is obtained before commencing the clinical trial. In April 2014, the EU passed the Clinical Trials Regulation
(Regulation 536/2014), which will replace the current Clinical Trials Directive. To ensure that the rules for clinical trials are
identical throughout the European Union, the EU Clinical Trials Regulation was passed as a regulation that is directly
applicable in all EU member states. All clinical trials performed in the European Union are required to be conducted in
accordance with the Clinical Trials Directive until the Clinical Trials Regulation becomes applicable. According to the
current plans of the EMA, the Clinical Trials Regulation is expected to become applicable sometime in 2020.

Data privacy and security laws

Numerous state, federal and foreign laws, including consumer protection laws and regulations, govern the collection,
dissemination, use, access to, confidentiality and security of personal information, including health-related information. In
the United States, numerous federal and state laws and regulations, including data breach notification laws, health
information privacy and security laws, including the Health Insurance Portability and Accountability Act of 1996, as
amended, or HIPAA, and federal and state consumer protection laws and regulations (e.g., Section 5 of the FTC Act), that
govern the collection, use, disclosure, and protection of health-related and other personal information could apply to our
operations or the operations of our partners. In addition, certain state and non-U.S. laws, such as the California Consumer
Privacy Act, or the CCPA, the California Privacy Rights Act, or the CPRA, and the European Union General Data Protection
Regulation, or the GDPR, govern the privacy and security of personal information, including health-related information in
certain circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant
ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws, where
applicable, can result in the imposition of significant civil and/or criminal penalties and private litigation. Privacy and
security laws, regulations, and other obligations are constantly evolving, may conflict with each other to complicate
compliance efforts, and can result in investigations, proceedings, or actions that lead to significant civil and/or criminal
penalties and restrictions on data processing.

Employees and Human Capital Resources

Employees

As of March 19, 2021, we had 87 employees, including 83 full-time employees. Women represent approximately 46%

of our employees with approximately 14% holding senior management level/leadership roles. Thirty-nine percent of our
employees have an M.D. or a Ph.D. From time to time, we also retain independent contractors to support our organization.
None of our employees are represented by a labor union or covered by collective bargaining agreements, and we believe our
relationship with our employees is good.

Diversity & Inclusion

We are committed to creating and maintaining a workplace free from discrimination or harassment on the basis of

color, race, sex, national origin, ethnicity, religion, age, disability, sexual orientation, gender identification or expression, or
any other status protected by applicable law. Our management team and employees are expected to exhibit and promote
honest, ethical and respectful conduct in the workplace. All of our employees must adhere to a code of conduct that sets
standards for appropriate behavior and are required to attend training upon hire and at our request to help prevent, identify,
report and stop any type of discrimination and harassment. Ongoing acknowledgement of our anti-harassment policy is
required on an annual basis. Our recruitment, hiring, development, training, compensation and advancement at our company
is based on qualifications, performance, skills and experience without regard to gender, race and ethnicity.

Competitive Pay & Benefits

We strive to provide pay, comprehensive benefits and services that help meet the varying needs of our employees. Our

total rewards package includes competitive pay; comprehensive healthcare benefits package for employees, with family
member healthcare benefits covered at 90%; a health savings account with company contribution; unlimited paid time off and
paid holidays; family medical leave; and flexible work schedules. In addition, we offer every full-time employee, both
exempt and non-exempt, the benefit of equity ownership in the company through stock option grants and our employee stock
purchase plan. We also sponsor a 401(k) plan with a 5% match.

Employee Development & Training

37

We focus on attracting, retaining, and cultivating talented individuals. We emphasize employee development and
training by providing access to a wide range of online and instructor led development and continual learning programs.
Employees are encouraged to attend scientific, clinical and technological meetings and conferences and have access to broad
resources they need to be successful.

Safety

The safety, health and wellness of our employees is a top priority. In response to COVID-19, we have implemented a
safety protocols including shift work scheduling to reduce number of people in the facility, requirements for the wearing of
masks and for social distancing, increased cleaning procedures and readily available hand sanitizer. These protocols are
designed to comply with health and safety standards as required by federal, state and local government agencies, taking into
consideration guidelines of the Centers for Disease Control and Prevention and other public health authorities. In addition,
we have provided work-at-home arrangements for employees who are able to do so.

Item 1A. Risk Factors.

Our future operating results could differ materially from the results described in this Annual Report on Form 10-K due

to the risks and uncertainties described below. You should consider carefully the following information about risks below in
evaluating our business. If any of the following risks actually occur, our business, financial conditions, results of operations
and future growth prospects would likely be materially and adversely affected. Additional risks and uncertainties not
presently known to us or that we currently deem immaterial also may impair our business operations in these circumstances,
the market price of our common stock would likely decline. In addition, we cannot assure investors that our assumptions and
expectations will prove to be correct. Important factors could cause our actual results to differ materially from those
indicated or implied by forward-looking statements. See “Forward Looking Statements” for a discussion of some of the
forward-looking statements that are qualified by these risk factors. Factors that could cause or contribute to such differences
include those factors discussed below.

Risks related to our financial position and need for additional capital

We have incurred significant losses since inception and anticipate that we will continue to incur losses for the foreseeable
future. We are not currently profitable, and we may never achieve or sustain profitability. If we are unable to achieve or
sustain profitability, the market value of our common stock will likely decline.

We are a clinical-stage biotechnology company with a limited operating history. As a result, we are not profitable and

have incurred significant losses since our formation. We had net losses of $26.5 million and $19.8 million for the years ended
December 31, 2020 and 2019, respectively. As of December 31, 2020, we had an accumulated deficit of $95.4 million.
Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital
expenditures and significant risk that any potential product candidate will fail to gain regulatory approval and become
commercially viable. We have not commercialized any products and have never generated revenue from the
commercialization of any product. To date, we have devoted most of our financial resources to licensing technologies and
research and development, including our preclinical platform development activities and clinical trials.

We expect to incur significant additional operating losses for the next several years, at least, as we advance FX-322 and

any other product candidate through clinical development, complete clinical trials, seek regulatory approval and
commercialize FX-322 or any other product candidate, if approved. The costs of advancing product candidates into each
clinical phase tend to increase substantially over the duration of the clinical development process. Therefore, the total costs to
advance any product candidate to marketing approval in even a single jurisdiction are substantial. Because of the numerous
risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or
amount of increased expenses or when, or if, we will be able to begin generating revenue from the commercialization of any
product candidates or achieve or maintain profitability. Our expenses will also increase substantially if and as we:

•

•

•

•

•

•

•

•

•

•

•

continue our Phase 2a trial of FX-322 in sensorineural hearing loss, or SNHL, our Phase 1b trial of FX-322 in
age-related hearing loss, or ARHL, and severe SNHL, and commence additional clinical studies relating to FX-
322, and any future pivotal Phase 3 studies;

expand our development programs based on our progenitor cell activation, or PCA, platform, including our
program for a treatment for multiple sclerosis, or MS, and develop other product candidates;

continue to develop our PCA platform;

seek regulatory approvals for FX-322 and any other product candidates;

expand the target indications and patient population for FX-322;

secure a commercial manufacturing source and supply chain capacity sufficient to produce commercial quantities
of any product candidate for which we obtain regulatory approval;

establish a sales, marketing and distribution infrastructure to commercialize FX-322 for the treatment of SNHL,
if approved, and for any other product candidates for which we may obtain marketing approval;

maintain, expand, and protect our intellectual property portfolio;

hire additional clinical, scientific, and commercial personnel;

add operational, financial, and management personnel, including personnel to support our product development
and planned future commercialization efforts, as well as to support operations as a public company; and

acquire or in-license other product candidates or technologies.

39

Furthermore, our ability to successfully develop, commercialize and license any product candidates and generate

product revenue is subject to substantial additional risks and uncertainties, as described under “—Risks related to
development, clinical testing, manufacturing, and regulatory approval” and “—Risks related to commercialization.” As a
result, we expect to continue to incur net losses and negative cash flows for the foreseeable future. These net losses and
negative cash flows have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital.
The amount of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to
generate revenues. If we are unable to develop and commercialize one or more product candidates, either alone or through
collaborations, or if revenues from any product that receives marketing approval are insufficient, we will not achieve
profitability. Even if we successfully commercialize FX-322, we may continue to incur substantial research and development
and other expenses to identify and develop other product candidates. Even if we do achieve profitability, we may not be able
to sustain profitability or meet outside expectations for our profitability. If we are unable to achieve or sustain profitability or
to meet outside expectations for our profitability, the value of our common stock will be materially adversely affected.

We will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be able
to complete the development and commercialization of FX-322 and additional product candidates.

We expect to spend substantial amounts to complete the development of, seek regulatory approvals for and, if

approved, commercialize FX-322. These expenditures include and will include, as the case may be, costs related to the Phase
2a trial of FX-322 for the treatment of SNHL, the Phase 1b trials of FX-322 for the treatment of ARHL and severe SNHL,
respectively, and any additional trials we conduct to support the development of FX-322. In addition, we are obligated to
make milestone and royalty payments in connection with the sale of resulting products and licensing revenues under our
license agreements with Massachusetts Institute of Technology, or MIT, Massachusetts Eye and Ear, or MEE, the Scripps
Research Institute, or Scripps, and Cambridge Enterprise Limited (the technology transfer arm of the University of
Cambridge), or Cambridge. We also expect to spend substantial amounts to identify and develop new product candidates
based on our PCA platform.

We will require additional capital to enable us to develop additional product candidates based on our PCA platform,

which we may acquire through equity offerings, debt financings, marketing and distribution arrangements and other
collaborations, strategic alliances and licensing arrangements or other sources. Adequate additional financing may not be
available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would have a negative effect on
our financial condition and our ability to pursue our business strategy. In addition, attempting to secure additional financing
may divert the time and attention of our management from day-to-day activities and harm our development efforts.

Based upon our current operating plan, we believe that our existing cash, cash equivalents, short-term investments of
$220.3 million will enable us to fund our operating expenses and capital expenditure requirements into 2023. This estimate
and our expectation regarding the sufficiency of our current financial resources to advance the clinical development of FX-
322 and any other product candidates are based on assumptions that may prove to be wrong, and we could use our available
capital resources sooner than we currently expect, or our clinical trials, including our Phase 2a trial of FX-322 for the
treatment of SNHL, our Phase 1b trials of FX-322 for the treatment of ARHL and severe SNHL, respectively, and other
planned clinical trials of FX-322, may be more expensive, time consuming or difficult to design or implement than we
currently anticipate. Changing circumstances, including any unanticipated expenses, could cause us to consume capital
significantly faster than we currently anticipate, and we may need to spend more than currently expected because of
circumstances beyond our control. Because the length of time and scope of activities associated with successful development
of FX-322 or any product candidate we may develop is highly uncertain, we are unable to estimate the actual funds we will
require for development and any marketing and commercialization activities. Our future funding requirements, both near and
long-term, will depend on many factors, including, but not limited to:

•

•

•

the initiation, progress, timing, costs and results of our clinical trials through all phases of development,
including the Phase 2a trial and Phase 1b ARHL and severe SNHL trials for FX-322, our other planned clinical
trials of FX-322, and the development of any other product candidates including any unforeseen costs we may
incur as a result of clinical trials due to the COVID-19 global pandemic or other causes;

the outcome, timing and cost of meeting regulatory requirements established by the U.S. Food and Drug
Administration, or the FDA, and other comparable foreign regulatory authorities, including any additional
clinical trials required by the FDA or other comparable foreign regulatory authorities;

the willingness of the FDA and other comparable foreign regulatory authorities to accept our clinical trial
designs, as well as data from our completed and planned clinical trials and preclinical studies, as the basis for
review and approval of FX-322 and any other product candidates;

40

•

•

•

•

•

•

•

•

•

•

the cost of filing, prosecuting, defending, and enforcing our patent claims and other intellectual property rights;

the cost of defending potential intellectual property disputes, including patent infringement actions brought by
third parties against us;

the effect of competing technological and market developments;

the cost and timing of completion of commercial-scale manufacturing activities;

the costs of operating as a public company;

the cost of making royalty, milestone or other payments under current and any future in-license agreements;

the extent to which we in-license or acquire other product candidates or technologies;

the cost of establishing sales, marketing and distribution capabilities for our product candidates, if approved;

our ability to maintain our collaboration with Astellas Pharma Inc., or Astellas, including achievement of the
development milestones and to establish new collaborations; and

the initiation, progress, and timing of our commercialization of FX-322, if approved, or any other product
candidate.

Depending on our business performance, the economic climate and market conditions, we may be unable to raise
additional funds through any sources. Market volatility resulting from the COVID-19 global pandemic could also adversely
impact our ability to access capital as and when needed. If we are unable to raise additional capital in sufficient amounts or
on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or
commercialization of FX-322 or any other product candidate, or potentially discontinue operations.

We have a limited operating history and no history of commercializing pharmaceutical products, which may make it
difficult to evaluate the prospects for our future viability.

We were established and began operations in 2014. Our operations to date have been limited to financing and staffing

our company, licensing technologies, developing our PCA platform, developing and conducting preclinical and clinical
studies of FX-322 for the treatment of SNHL, and developing a pipeline of preclinical and research programs, including our
program for the treatment of MS. We have not yet demonstrated the ability to successfully complete a large-scale, pivotal
clinical trial, obtain marketing approval, manufacture a commercial-scale product, or arrange for a third party to do so on our
behalf, or conduct sales and marketing activities necessary for successful product commercialization. Consequently,
predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history
or a history of successfully developing and commercializing pharmaceutical products.

In addition, as a business with a limited operating history, we may encounter unforeseen expenses, difficulties,
complications, delays and other known and unknown challenges. Our interim Phase 2a results, for example, showed that four
weekly injections in subjects with mild to moderately severe SNHL did not demonstrate improvements in hearing measures
versus placebo, which results were unexpected. We will eventually need to transition from a company with a research focus
to a company capable of supporting commercial activities. We may not be successful in such a transition and, as a result, our
business may be adversely affected.

As we continue to build our business, we expect our financial condition and operating results may fluctuate
significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control.
Accordingly, the results of any quarterly or annual period are not necessarily indicative of future operating performance.

Our ability to use our net operating loss carryforwards to offset future taxable income, or tax credit carryforward to offset
future income tax liabilities, may be subject to certain limitations.

As of December 31, 2020, we had net operating loss carryforwards, or NOLs, of $67.9 million for federal income tax

purposes and $43.4 million for state income tax purposes, which may be available to offset our future taxable income, if any.
Our NOLs begin to expire in various amounts in 2037, provided that federal NOLs generated in taxable years beginning after
December 31, 2017 will not be subject to expiration. As of December 31, 2020, we also had federal and state research and
development and other tax credit carryforwards of approximately $3.0 million and $1.2 million, respectively, available to
reduce future tax liabilities. Our tax credit carryforwards expire at various dates through 2040. These NOLs and tax credit

41

carryforwards could expire unused, to the extent subject to expiration, and be unavailable to offset future income tax
liabilities. In addition, in general, under Sections 382 and 383 of the U.S. Internal Revenue Code of 1986, as amended, or the
Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to use its pre-change NOLs
and tax credit carryforwards to offset future taxable income. For these purposes, an ownership change generally occurs where
the aggregate stock ownership of one or more stockholders or groups of stockholders who owns at least 5% of a corporation’s
stock increases its ownership by more than 50 percentage points over its lowest ownership percentage within a specified
testing period. We believe we have experienced an ownership change in 2017 and 2019 and may experience ownership
changes in the future as a result of future transactions in our stock, some of which may be outside our control. If we undergo
additional ownership changes, our ability to use our NOLs and tax credit carryforwards could be further limited. As a result
of the changes in ownership in 2017 and 2019, $0.01 million and $0.04 million of NOL carryforwards are limited under
Section 382. For these reasons, we may not be able to use a material portion of our NOLs or tax credit carryforwards, even if
we attain profitability. We have recorded a full valuation allowance related to our NOLs and other deferred tax assets due to
the uncertainty of the ultimate realization of the future tax benefits of such assets. Furthermore, NOLs generated in periods
beginning after December 31, 2017 may be carried forward indefinitely but may only be used to offset 80% of our taxable
income in years beginning after December 31, 2020, which may require us to pay federal income taxes in future years despite
generating federal NOLs in prior years.

Risks related to development, clinical testing, manufacturing, and regulatory approval

We are heavily dependent on the success of FX-322, our lead product candidate, which is still under clinical development,
and if FX-322 does not receive regulatory approval or is not successfully commercialized, our business will be materially
adversely harmed.

To date, we have invested a significant portion of our efforts and financial resources in the development of FX-322 for

the treatment of SNHL. Our future success is substantially dependent on our ability to successfully complete clinical
development for, obtain regulatory approval for, and successfully commercialize FX-322, which may never occur. We
currently have no products that are approved for commercial sale and may never be able to develop a marketable product. We
expect that a substantial portion of our efforts and expenditures over the next few years will continue to be devoted to FX-
322, which will require additional clinical development, management of clinical and manufacturing activities, regulatory
approval, establishing commercial scale manufacturing, and significant sales, marketing, and distribution efforts before we
can generate any revenues from any commercial sales. We cannot be certain that we will be able to successfully complete any
of these activities or that, even if it receives regulatory approval, FX-322 will be as effective as anticipated at treating SNHL.
Our interim Phase 2a results, for example, showed that four weekly injections in subjects with mild to moderately severe
SNHL did not demonstrate improvements in hearing measures versus placebo.

The research, testing, manufacturing, labeling, approval, sale, packaging, marketing, and distribution of drug products

are subject to extensive regulation by the FDA and comparable regulatory authorities in other countries. We are not permitted
to market FX-322 in the United States until we receive approval of a New Drug Application, or NDA, from the FDA, or in
any foreign countries until our collaborator, Astellas, receives the requisite approval from such countries. We have not
submitted an NDA to the FDA and Astellas has not submitted comparable applications to other regulatory authorities for FX-
322. We or Astellas may not be in a position to do so for several years, if ever. If we or Astellas are unable to obtain the
necessary regulatory approval for FX-322 in a country, including as a result of the COVID-19 pandemic, we or Astellas will
not be able to commercialize FX-322 for the treatment of SNHL in that country. As a result, our financial position will be
materially adversely affected, and we may not be able to generate sufficient revenue to continue our business.

We utilize our PCA platform to develop product candidates that are designed to activate progenitor cells, which is a new
approach to therapeutic intervention and, as a result, successful development, approval, and commercialization of our
product candidates, including FX-322, is uncertain.

We utilize our PCA platform to develop product candidates, including FX-322, for the treatment of SNHL. Our PCA

platform is designed to identify pathways to activate progenitor cells already present in the body to treat conditions or
diseases through cellular regeneration. We have not, nor to our knowledge has any other company, received regulatory
approval utilizing this mechanism of cellular regeneration. Given the novelty of our approach, we could encounter a longer
than expected regulatory review process, increased development costs, or unexpected delays in, or even prevention of, the
regulatory approval and commercialization of our product candidates, and we cannot be certain that our approach will lead to
the development of any approvable or marketable products. For example, the FDA-approved treatment options available for
patients with SNHL are hearing aids and cochlear implants. Unlike FX-322, which is a therapeutic that targets the underlying

42

biology of SNHL, these treatment options are medical devices that are designed to target the symptoms of SNHL. As a result,
these treatment options are not directly comparable to FX-322, and FDA requirements for marketing authorization of these
treatment options may not be relevant for FX-322. While we are developing what we believe are appropriate measurements
of efficacy for FX-322, we cannot be certain that the FDA will agree with our measurements or that they will be sufficient for
approval. If we were to encounter any of the foregoing, our business and financial prospects could be materially harmed.

Clinical trials are expensive, time consuming, and difficult to design and implement, and involve an uncertain outcome.
The results of preclinical studies and early clinical trials are not always predictive of future results. Any product candidate
that we advance into clinical trials may not achieve favorable results in later clinical trials, if any, or receive marketing
approval.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can

occur at any time during the clinical trial process. The results of preclinical studies and completed clinical trials are not
necessarily predictive of future results, and any product candidates we develop may not be further developed or may have
additional unfavorable results in later studies or trials. Clinical trial failure may result from a multitude of factors, including,
but not limited to, flaws in study design, dose selection, placebo effect, patient enrollment criteria, selection of patients based
on patient misrepresentations, and failure to demonstrate favorable safety or efficacy traits. As such, failure in clinical trials
can occur at any stage of testing. Several companies in the pharmaceutical industry have suffered setbacks in the
advancement of their drug candidates into later-stage clinical trials due to lack of efficacy or adverse safety profiles,
notwithstanding favorable results in earlier preclinical studies or clinical trials. Our interim Phase 2a results, for example,
showed that four weekly injections in subjects with mild to moderately severe SNHL did not demonstrate improvements in
hearing measures versus placebo. Based upon negative or inconclusive results or a need for additional information, we may
decide, or regulatory authorities may require us, to conduct additional clinical trials or preclinical studies.

We may experience delays in initiating and completing any clinical trials that we intend to conduct, and we do not

know whether our clinical trials will begin on time, need to be redesigned, enroll patients on time, or be completed on
schedule, or at all. For example, a number of clinical trial sites for our ongoing Phase 2a clinical trial of FX-322 temporarily
halted patient enrollment during the first and second quarter of 2020 in response to the COVID-19 pandemic. While we were
able to complete enrollment of our Phase 2 clinical trial in September 2020, enrollment in other ongoing clinical trials could
be adversely affected by the pandemic. Clinical trials can be delayed for a variety of reasons, including delays related to:

•

•

•

•

•

•

•

•

•

•

•

•

the FDA or comparable foreign regulatory authorities disagreeing as to the design or implementation of our
clinical studies;

obtaining regulatory approval to commence a trial;

reaching an agreement on acceptable terms with prospective contract research organizations, or CROs, and
clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among
different CROs and trial sites;

obtaining Institutional Review Board, or IRB, approval at each site within the United States, or Independent
Ethics Committee, or IEC, approval at sites outside the United States;

business interruptions resulting from the COVID-19 pandemic;

recruiting suitable patients to participate in a trial in a timely manner and in sufficient numbers;

having patients complete a trial or return for post-treatment follow-up;

imposition of a clinical hold by regulatory authorities, including as a result of unforeseen safety issues or side
effects or failure of trial sites or investigators to adhere to regulatory requirements or follow trial protocols;

clinical sites deviating from the trial protocol or dropping out of a trial;

addressing patient safety concerns that arise during a trial;

adding a sufficient number of clinical trial sites; or

manufacturing sufficient quantities of a product candidate for use in clinical trials.

We could also encounter delays if a clinical trial is suspended or terminated by us, the IRBs or IECs of the institutions
in which such trials are being conducted, the FDA or other regulatory authorities, or recommended for termination by a Data
and Safety Monitoring Board, or DSMB, for such trial. Such authorities may impose a suspension or termination or

43

recommend an alteration due to a number of factors, including failure to conduct the clinical trial in accordance with
regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other
regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to
demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions, or lack of adequate
funding to continue the clinical trial.

Furthermore, we rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and,
while we have agreements governing their committed activities, we have limited influence over their actual performance, as
described in the section titled “—Risks related to our dependence on third parties.”

Our lead product candidate, FX-322, is still in development and will require the successful completion of one, and

possibly more, Phase 3 trials before we are prepared to submit an NDA for regulatory approval by the FDA. In addition, we
have been advised by the FDA that, while the nonclinical studies conducted by us to date suggest a pharmacodynamic
interaction between the two active components of FX-322, the FDA has indicated that the results of such nonclinical studies
do not preclude a human study and that inclusion of a factorial study in humans in future trials of FX-322 would thoroughly
assess the effects attributable to each component drug of FX-322 in the combination so as to satisfy the FDA’s combination
rule. The design and conduct of a factorial study in humans, including the development of each active component to
administer in such study, may cause additional delays in the development of FX-322. We cannot predict with any certainty if
or when we might complete the development of FX-322 and submit an NDA for regulatory approval by the FDA of FX-322
or whether any such NDA will be approved by the FDA.

If we experience delays in the commencement or completion of any clinical trials, or if we terminate a clinical trial

prior to completion, the commercial prospects of any product candidate we develop could be harmed, and our ability to
generate revenues may be delayed. In addition, any delays in our clinical trials could increase our costs, slow the
development and approval process and jeopardize our ability to commence product sales and generate revenues. Any of these
occurrences may materially harm our business, financial condition, and results of operations. In addition, many of the factors
that may cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial
of regulatory approval of our product candidates.

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

The regulatory approval processes of the FDA and comparable foreign regulatory authorities are lengthy, time-
consuming, and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for FX-322 or any
other product candidates, our business will be substantially harmed.

The time required to obtain approval by the FDA and comparable foreign regulatory authorities is unpredictable but

typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the
substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount of
clinical data necessary to gain approval may change during a product candidate’s clinical development and may vary among
jurisdictions. The approval process may also be delayed by changes in government regulation, the impact of the COVID-19
pandemic, future legislation or administrative action. We have not obtained regulatory approval for any product candidate
and it is possible that we will never obtain regulatory approval for any product candidate. We are not permitted to market any
of our product candidates in the United States until we receive approval of an NDA from the FDA.

Prior to obtaining approval to commercialize a product candidate in the United States or abroad, we must demonstrate

with substantial evidence from well-controlled clinical trials, and to the satisfaction of the FDA or comparable foreign
regulatory authority, that such product candidates are safe and effective for their intended uses. In addition, data obtained
from preclinical trials and clinical trials are susceptible to varying interpretations, and regulatory authorities may not interpret
our data as favorably as we do, which may further delay, limit, or prevent development efforts, clinical trials, or marketing
approval. Furthermore, as more competing drug candidates within a class of drugs proceed through clinical development to
regulatory review and approval, the amount and type of clinical data that may be required by regulatory authorities may

44

increase or change. Even if we believe the preclinical or clinical data for our product candidates are promising, such data may
not be sufficient to support approval by the FDA and other comparable regulatory authorities.

The FDA or any foreign regulatory authority can delay, limit, or deny approval of FX-322 or any other product
candidates that we develop or require us to conduct additional preclinical or clinical testing or abandon a program for many
reasons, including:

•

•

•

•

•

•

•

•

•

•

the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our
clinical trials;

we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that
a product candidate is safe and effective for its proposed indication;

serious and unexpected drug-related side effects experienced by participants in our clinical trials or by
individuals using drugs similar to our product candidates, or other products containing an active ingredient in our
product candidates;

negative or ambiguous results from our clinical trials or results that may not meet the level of statistical
significance required by the FDA or comparable foreign regulatory authorities for approval;

we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks;

the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from
preclinical studies or clinical trials;

the data collected from clinical trials of our product candidates may not be acceptable or sufficient to support the
submission of an NDA or other submission or to obtain regulatory approval in the United States or elsewhere,
and we may be required to conduct additional clinical trials;

the FDA’s or the applicable foreign regulatory authority’s disagreement regarding the formulation, the labeling,
and/or the specifications of our product candidates;

the FDA or comparable foreign regulatory authorities may fail to approve or find deficiencies with the
manufacturing processes or facilities of third-party manufacturers with which we contract for clinical and
commercial supplies; and

the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly
change in a manner rendering our clinical data insufficient for approval.

Of the large number of drugs in development, only a small percentage successfully complete the regulatory approval

processes and are commercialized. This lengthy approval process, as well as the unpredictability of future clinical trial
results, may result in our failing to obtain regulatory approval to market our product candidates, which would significantly
harm our business, results of operations, and prospects.

In addition, the FDA or the applicable foreign regulatory authority also may approve a product candidate for a more

limited indication or patient population than we originally requested, and the FDA or applicable foreign regulatory authority
may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the
successful commercialization of that product candidate. Any of the foregoing circumstances could materially harm the
commercial prospects for our product candidates and our business.

Enrollment and retention of patients in clinical trials is an expensive and time-consuming process and could be made
more difficult or rendered impossible by multiple factors outside our control.

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability
to enroll a sufficient number of patients who remain in the study until its conclusion. We may encounter delays in enrolling,
or be unable to enroll, a sufficient number of patients to complete any of our clinical trials, and even once enrolled, we may
be unable to retain a sufficient number of patients to complete any of our trials.

Patient enrollment and retention in clinical trials depends on many factors, including:

•

the extent of the ongoing COVID-19 pandemic, see --- The COVID-19 pandemic could adversely impact our
business, including our preclinical studies, clinical trials and operations;

45

•

•

•

•

•

•

•

•

•

•

the patient eligibility criteria defined in the protocol, such as the requirement to establish stable hearing loss in
our Phase 2a and Phase 1b clinical trials;

the size of the patient population required for analysis of the trial’s primary endpoints;

the nature of the trial protocol, trial design, side effects or other results that may arise in development;

the existing body of safety and efficacy data with respect to the product candidate;

the proximity of patients to clinical sites;

our ability to recruit clinical trial investigators with the appropriate competencies, motivation and experience;

clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in
relation to other available therapies, including any new drugs or medical devices that may be approved for the
indications we are investigating;

competing clinical trials being conducted by other companies or institutions;

our ability to obtain and maintain patient consents; and

the risk that patients enrolled in clinical trials will drop out of the trials before completion.

In addition, our clinical trials will compete with other clinical trials for product candidates and medical devices that are

in the same therapeutic areas as our product candidates, and this competition will reduce the number and types of patients
available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being
conducted by one of our competitors. Furthermore, any negative results we may report in clinical trials of any product
candidate may make it difficult or impossible to recruit and retain patients in other clinical trials of that same product
candidate. Delays or failures in planned patient enrollment or retention may result in increased costs or program delays,
which could have a harmful effect on our ability to develop a product candidate or could render further development
impossible.

Results of preclinical studies, clinical trials, or analyses may not be indicative of results that may be obtained in later
trials.

The results of preclinical studies, clinical trials, or analyses of the results from such trials, including our prospective

and post hoc analyses of the data from the Phase 1/2 trial of FX-322 for the treatment of SNHL, may not be predictive of the
results of later clinical trials. Product candidates in later clinical trials may fail to show the desired safety and efficacy traits
despite having progressed through preclinical studies and prior clinical trials or having shown promising results based on
analyses of data from earlier trials. A number of companies in the pharmaceutical industry have suffered significant setbacks
in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding earlier promising results. Our
interim Phase 2a results, for example, showed that four weekly injections in subjects with mild to moderately severe SNHL
did not demonstrate improvements in hearing measures versus placebo. In addition, conclusions based on promising data
from analyses of clinical results, such as the prospective and post hoc analysis of results from our Phase 1/2 clinical trial of
FX-322 for the treatment of SNHL, may be shown to be incorrect in subsequent clinical trials that have pre-specified end
points or may not be considered adequate by regulatory authorities. Even if we complete later clinical trials as planned, we
cannot be certain that their results will support the safety and efficacy requirements sufficient to obtain regulatory approval,
and, as a result, our clinical development plans may be materially harmed.

Interim and preliminary “top-line” data from our clinical trials that we announce or publish from time to time may
change as more patient data become available and are subject to audit and verification procedures that could result in
material changes in the final data.

From time to time, we may publicly disclose interim, top-line or preliminary data from our clinical trials, which is
based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to
change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions,
estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the
opportunity to fully and carefully evaluate all data. As a result, the top-line or preliminary results that we report may differ
from future results of the same studies, or different conclusions or considerations may qualify such results, once additional
data have been received and fully evaluated. Top-line or preliminary data also remain subject to audit and verification
procedures that may result in the final data being materially different from the top-line or preliminary data we previously
published. As a result, top-line and preliminary data should be viewed with caution until the final data are available.

46

From time to time, we may also disclose interim data from our preclinical studies and clinical trials. Interim data from
clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as
patient enrollment continues and more patient data become available. Adverse differences between interim data and final data
could significantly harm our business prospects. Further, disclosure of interim data by us or by our competitors could result
in volatility in the price of our common stock.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations,

conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the
particular program, the approvability or commercialization of the particular product candidate or product and our company in
general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on
what is typically extensive information, and you or others may not agree with what we determine is material or otherwise
appropriate information to include in our disclosure.

If the interim, top-line or preliminary data that we report differ from actual results, or if others, including regulatory

authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product
candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Any product candidate or component of a product candidate that we develop or the administration thereof, may cause
serious adverse events or undesirable side effects, which may halt their clinical development, delay or prevent marketing
approval, or, if approved, require them to be taken off the market, include safety warnings, or otherwise limit their sales.

Serious adverse events or undesirable side effects caused by any product candidate or component of a product
candidate we develop could cause us or regulatory authorities to interrupt, delay, or halt clinical trials and could result in a
more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign regulatory
authorities. Results of any clinical trial we conduct could reveal a high and unacceptable severity and prevalence of side
effects. In our clinical studies to date, subjects treated with FX-322 have experienced adverse events that include ear
discomfort and ear pain that are considered to be associated with the intratympanic injection procedure.

If unacceptable side effects arise in the development of any product candidate, we, the FDA, or the IRBs or IECs at the

institutions in which our studies are conducted, or the DSMB, if constituted for our clinical trials, could recommend a
suspension or termination of our clinical trials, or the FDA or comparable foreign regulatory authorities could order us to
cease further development of or deny approval of a product candidate for any or all targeted indications. In addition, drug-
related side effects could affect patient recruitment or the ability of enrolled patients to complete a trial or result in potential
product liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating
medical staff. We may have to train medical personnel regarding the proper administration protocol for our product
candidates and to understand the side effect profiles for our clinical trials and upon any commercialization of any of our
product candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates could
result in patient injury or death. Any of these occurrences may harm our business, financial condition, and prospects
significantly.

Additionally, if FX-322 or any other product candidate we develop receives marketing approval, and we or others later

identify undesirable side effects caused by such products, a number of potentially significant negative consequences could
result, including:

•

•

•

•

•

•

regulatory authorities may suspend, withdraw, or limit approvals of such product, or seek an injunction against
its manufacture or distribution;

regulatory authorities may require us to recall a product or we may decide to initiate a voluntary recall of a
product;

regulatory authorities may require additional warnings on the label, such as a “black box” warning or
contraindication;

additional restrictions may be imposed on the marketing of the product or the manufacturing processes for the
product or any component thereof;

we may be required to implement a Risk Evaluation and Mitigation Strategy, or REMS, or create a medication
guide outlining the risks of such side effects for distribution to patients;

we may be required to conduct post-market studies or agree to post marketing commitments;

47

•

•

•

we could be sued and held liable for harm caused to patients;

the product may become less competitive; and

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of a product candidate, if

approved, and could significantly harm our business, results of operations, and prospects.

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could
hinder their ability to hire and retain key leadership and other personnel, or otherwise prevent new products and services
from being developed or commercialized in a timely manner, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including
government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and
statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In
addition, government funding of other government agencies that fund research and development activities is subject to the
political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed or approved

by necessary government agencies, which would adversely affect our business. For example, over the last several years,
including for 35 days beginning on December 22, 2018, the U.S. government has shut down several times and certain
regulatory agencies, such as the FDA, have had to furlough critical employees and stop critical activities. If a prolonged
government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory
submissions, which could have a material adverse effect on our business.

Separately, in response to the COVID-19 pandemic, on March 10, 2020 the FDA announced its intention to postpone

most inspections of foreign manufacturing facilities and on March 18, 2020, the FDA temporarily postponed routine
surveillance inspections of domestic manufacturing facilities. Subsequently, on July 10, 2020 the FDA announced its
intention to resume certain on-site inspections of domestic manufacturing facilities subject to a risk-based prioritization
system. The FDA intends to use this risk-based assessment system to identify the categories of regulatory activity that can
occur within a given geographic area, ranging from mission critical inspections to resumption of all regulatory activities.
Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the
COVID-19 pandemic or issue guidance materially affecting the conduct of clinical trials. If a prolonged government
shutdown occurs, or it global health concerns continue to prevent the FDA or other regulatory authorities from conducting
their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA to timely
review and process our regulatory submissions, which could have a material adverse effect on our business. Further, in our
operations as a public company, future government shutdowns or delays could impact our ability to access the public markets
and obtain necessary capital in order to properly capitalize and continue our operations.

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, the choice of which may prove to be wrong and
adversely affect our business.

Although we intend to explore additional product candidates based on our PCA platform, we may fail to identify viable

new product candidates for clinical development for several reasons. If we fail to identify additional potential product
candidates, our business could be materially harmed.

Research programs to develop additional product candidates based on our PCA platform 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 or product candidates, yet fail to yield results for clinical development for several
reasons, including:

•

•

•

the research methodology used may not be successful in identifying potential indications or product candidates;

potential product candidates may, after further study, be shown to have harmful or unexpected 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 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 product portfolio.

48

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 could 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. For example, we may encounter delays in the process of
selecting a product candidate for the treatment of MS and we may not achieve the timeline we currently anticipate for
submitting an IND or comparable foreign equivalent. We may focus our efforts and resources on potential product candidates
or other potential programs that ultimately prove to be unsuccessful.

The market opportunities for FX-322, if approved, may be smaller than we anticipate and, as a result, our commercial
opportunity may be limited.

We expect to initially seek approval of FX-322 for the treatment of SNHL. Our projections of the number of eligible

patients are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including
scientific literature, patient foundations, and market research, and may prove to be incorrect. Further, new sources may reveal
a change in the estimated number of eligible patients, and the number of patients may turn out to be lower than expected.
Additionally, the potentially addressable patient population for our current programs or future product candidates may be
limited. For example, even if we obtain FDA approval for FX-322, it may be approved for a target population that is more
limited than what we currently anticipate. Even if we obtain significant market share for any product candidate, if approved,
if the potential target populations are smaller, we may never achieve profitability without obtaining marketing approval for
additional indications.

We have never obtained marketing approval for a product candidate and we may be unable to obtain, or may be delayed in
obtaining, marketing approval for any product candidate.

We have never obtained marketing approval for a product candidate. It is possible that the FDA may refuse to accept

for substantive review any NDAs that we submit for our product candidates or may conclude after review of our data that our
applications are insufficient to obtain marketing approval of our product candidates. We believe our approach of activating
progenitor cells to treat conditions or diseases through cellular regeneration is novel and, as a result, the process for, and the
outcome of, FDA approval is especially uncertain. If the FDA does not accept or approve our NDAs for our product
candidates, it may require that we conduct additional clinical, preclinical, or manufacturing validation studies and submit that
data before it will reconsider our applications. Depending on the extent of these or any other FDA-required studies, approval
of any NDA that we submit may be delayed or may require us to expend more resources than we have available. It is also
possible that additional studies, if performed and completed, may not be considered sufficient by the FDA to approve our
NDAs.

Any delay in obtaining, or an inability to obtain, marketing approvals would prevent us from commercializing our
product candidates, generating revenues, and achieving and sustaining profitability. If any of these outcomes occur, we may
be forced to abandon our development efforts for our product candidates, which could significantly harm our business.

Even if we obtain FDA approval for a product candidate in the United States, we or our collaborators may never obtain
approval for or commercialize the product candidate in any other jurisdiction, which would limit our ability to realize its
full market potential.

In order to market any product in a particular jurisdiction, we or our collaborators must establish and comply with
numerous and varying regulatory requirements regarding safety and efficacy on a country-by-country basis. Approval by the
FDA in the United States does not ensure approval by comparable regulatory authorities in other countries or jurisdictions.
However, the failure to obtain approval in one jurisdiction may negatively impact our or our collaborators’ ability to obtain
approval elsewhere. In addition, clinical trials conducted in one country may not be accepted by regulatory authorities in
other countries, and regulatory approval in one country does not guarantee regulatory approval in any other country.

Approval processes vary among countries and can involve additional product testing and validation and additional
administrative review periods. Seeking foreign regulatory approval could result in difficulties and increased costs for us and
require additional preclinical studies or clinical trials which could be costly and time- consuming. Regulatory requirements

49

can vary widely from country to country and could delay or prevent the introduction of our products in those countries. We
do not have any product candidates approved for sale in any jurisdiction, including in international markets, and we do not
have experience in obtaining regulatory approval in international markets. If we or our collaborators fail to comply with
regulatory requirements in international markets or to obtain and maintain required approvals, or if regulatory approvals in
international markets are delayed, our target market will be reduced and we will be unable to realize the full market potential
of any product we develop.

Even if we obtain regulatory approval for any product candidate, we will still face extensive and ongoing regulatory
requirements and obligations, which may result in significant additional expense, and any product candidates, if
approved, may face future development and regulatory difficulties.

Any product candidate for which we obtain marketing approval, along with the manufacturing processes, post-approval

clinical data, labeling, packaging, distribution, adverse event reporting, storage, recordkeeping, export, import, and
advertising and promotional activities for such product, among other things, will be subject to extensive and ongoing
requirements of and review by the FDA and other regulatory authorities. These requirements include submissions of safety
and other post-marketing information and reports, establishment registration and drug listing requirements, continued
compliance with current Good Manufacturing Practice, or cGMP, requirements relating to manufacturing, quality control,
quality assurance, and corresponding maintenance of records and documents, requirements regarding the distribution of
samples to physicians and recordkeeping and Good Clinical Practice, or GCP, and requirements for any clinical trials that we
conduct post-approval.

Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the
indicated uses for which the product candidate may be marketed or to the conditions of approval, including a requirement to
implement a REMS. If a product candidate receives marketing approval, the accompanying label may limit the approved
indicated use of the product, which could limit sales of the product. The FDA may also require costly post-marketing studies
or clinical trials and surveillance to monitor the safety or efficacy of a product. The FDA closely regulates the post-approval
marketing and promotion of drugs to ensure drugs are marketed only for the approved indications and in accordance with the
provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding
off-label use, and if we market our products for uses beyond their approved indications, we may be subject to enforcement
action for off-label marketing. Violations of the Federal Food, Drug, and Cosmetic Act, or FDCA, relating to the promotion
of prescription drugs, may lead to FDA enforcement actions and investigations alleging violations of federal and state
healthcare fraud and abuse laws, as well as state consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with our products, manufacturers,

or manufacturing processes or failure to comply with regulatory requirements, may yield various results, including:

•

•

•

•

•

•

•

•

•

•

•

•

restrictions on manufacturing such products;

restrictions on the labeling or marketing of products;

restrictions on product distribution or use;

requirements to conduct post-marketing studies or clinical trials;

warning letters or untitled letters;

refusal to approve pending applications or supplements to approved applications that we submit;

recalls or market withdrawals of products;

fines, restitution, or disgorgement of profits or revenues;

suspension or withdrawal of marketing approvals;

refusal to permit the import or export of our products;

product seizure; or

injunctions, consent decrees, or the imposition of civil or criminal penalties.

Further, the FDA’s policies may change, and additional government regulations may be enacted that could prevent,

limit, or delay regulatory approval of a product candidate. 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

50

may lose any marketing approval that we may have obtained, which would adversely affect our business, prospects, and
ability to achieve or sustain profitability.

We also cannot predict the likelihood, nature, or extent of government regulation that may arise from future legislation
or administrative or executive action, either in the United States or abroad. The policies of the FDA and of other comparable
regulatory authorities may change and additional government regulations may be enacted that could prevent, limit, or delay
regulatory approval of a product candidate. For example, the results of the 2020 U.S. Presidential election may impact our
business and industry. Namely, the previous presidential administration took several executive actions, including the issuance
of a number of Executive Orders, that could impose significant burdens on, or otherwise materially delay, the FDA’s ability
to engage in routine regulatory and oversight activities such as implementing statutes through rulemaking, issuance of
guidance, and review and approval of marketing applications. It is difficult to predict whether or how these actions will be
implemented, or whether they will be rescinded and replaced under the new presidential administration. The policies and
priorities of the new administration are unknown and could materially impact the regulatory framework governing our
product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements
or policies, or if we are not able to maintain regulatory compliance, we may be subject to enforcement action, and we may
not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition, and results of
operations. Furthermore, noncompliance by us or any collaborator with regulatory requirements, including safety monitoring
or pharmacovigilance, may also result in significant financial penalties, which would adversely affect our business.

We received Fast Track designation by the FDA for FX-322 and may seek Fast Track designation by the FDA for any
future product candidates, but we might not receive such a designation. However, such designation may not lead to a
faster development or regulatory review or approval process.

In October 2019, FX-322 received Fast Track designation by the FDA. If a drug is intended for the treatment of a

serious condition and nonclinical or clinical data demonstrate the potential to address an unmet medical need for this
condition, a drug sponsor may qualify for FDA Fast Track designation. Fast Track designation provides increased
opportunities for sponsor meetings with the FDA during preclinical and clinical development, in addition to the potential for
rolling review once a marketing application is filed. The FDA has broad discretion whether to grant Fast Track designation,
and we may not receive such a designation for all of the product candidates for which we may request it. Moreover, even if
we receive Fast Track designation, Fast Track designation does not ensure that we will receive marketing approval or that
approval will be granted within any particular time frame. We may not experience a faster development or regulatory review
or approval process with Fast Track designation compared to conventional FDA procedures. In addition, the FDA may
withdraw Fast Track designation if it believes that the designation is no longer supported by data from our clinical
development program. Fast Track designation alone does not guarantee qualification for the FDA’s priority review
procedures.

We may seek a Breakthrough Therapy designation for FX-322 and our other product candidates, but we might not receive
such designation, and even if we do, such designation may not lead to a faster development or regulatory review or
approval process.

We may seek a Breakthrough Therapy designation for FX-322 if results from our ongoing clinical trials support such

designation and we may seek a Breakthrough Therapy designation for other product candidates we may develop. A
Breakthrough Therapy is defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a
serious condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over
existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in
clinical development. For drugs that have been designated as breakthrough therapies, interaction and communication between
the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing
the number of patients placed in ineffective control regimens. Drugs designated as breakthrough therapies by the FDA may
also be eligible for priority review if supported by clinical data at the time the NDA is submitted to the FDA.

Designation as a Breakthrough Therapy is within the discretion of the FDA. Accordingly, even if we believe that a
product candidate meets the criteria for designation as a Breakthrough Therapy, the FDA may disagree and instead determine
not to make such a designation. Even if we receive Breakthrough Therapy designation, the receipt of such designation may
not result in a faster development or regulatory review or approval process compared to drugs considered for approval under
conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if a product candidate
qualifies as a Breakthrough Therapy, the FDA may later decide that it no longer meets the conditions for qualification or
decide that the time period for FDA review or approval will not be shortened.

51

Potential product liability lawsuits against us could cause us to incur substantial liabilities and limit commercialization of
any products that we may develop.

The use of any product candidate we may develop in clinical trials and the sale of any products for which we obtain

marketing approval exposes us to the risk of product liability claims. Product liability claims might be brought against us by
patients, healthcare providers, pharmaceutical companies or others selling or otherwise coming into contact with our
products. On occasion, large judgments have been awarded in class action lawsuits based on drugs that had unanticipated
adverse effects. If we cannot successfully defend against product liability claims, we could incur substantial liability and
costs. In addition, regardless of merit or eventual outcome, product liability claims may result in:

•

•

•

•

•

•

•

•

•

impairment of our business reputation and significant negative media attention;

withdrawal of participants from our clinical trials;

significant costs to defend the litigation;

distraction of management’s attention from our primary business;

substantial monetary awards to patients or other claimants;

inability to commercialize a product candidate;

product recalls, withdrawals or labeling, marketing or promotional restrictions;

decreased market demand for any product; and

loss of revenue.

The product liability insurance we currently carry, and any additional product liability insurance coverage we acquire
in the future, may not be sufficient to reimburse us for any expenses or losses we may suffer. Moreover, insurance coverage
is becoming increasingly expensive and, in the future, we may not be able to maintain insurance coverage at a reasonable cost
or in sufficient amounts to protect us against losses due to liability. If we obtain marketing approval for any product
candidate, we intend to acquire insurance coverage to include the sale of commercial products; however, we may be unable to
obtain product liability insurance on commercially reasonable terms or in adequate amounts. A successful product liability
claim, or series of claims, brought against us could cause our share price to decline and, if judgments exceed our insurance
coverage, could adversely affect our results of operation and business, including preventing or limiting the commercialization
of any product candidates we develop.

The COVID-19 pandemic has caused and could continue to cause disruptions to our business, including our preclinical
studies, clinical trials and operations and could adversely impact our financial condition and results of operations.

In March 2020, the World Health organization designated the outbreak of the novel strain of coronavirus, known as
COVID-19, as a global pandemic. This virus has and continues to spread globally and governments and businesses around
the world have taken unprecedented actions to mitigate the spread of COVID-19, including, but not limited to, shelter-in-
place orders, business closures, quarantines, border closures, significant restrictions on travel, social distancing practices as
well as restrictions that prohibit many employees from going to work. The pandemic, and government measures taken in
response, have had a significant impact, both direct and indirect, on business and commerce, as worker shortages have
occurred; supply chains have been disrupted; facilities and production have been suspended; and demand for certain goods
and services, such as medical services and supplies, has spiked, while demand for other goods and services, such as travel,
has fallen.

On March 23, 2020, the governor of Massachusetts ordered the closure of all non-essential businesses, effective March
24, 2020 through April 7, 2020, which was subsequently extended through May 18, 2020. The governor of Massachusetts has
since implemented a phased re-opening plan. Since December 2020, several vaccines combating COVID-19 have been
granted emergency use authorization by the FDA and are being administered.

In light of recent developments relating to the COVID-19 pandemic, the focus of healthcare providers and hospitals has

been on fighting the virus and vaccinating the public and we have been required to take steps consistent with the FDA’s
updated industry guidance for conducting clinical trials issued on March 18, 2020. The majority of our employees have
continued to work from home, while nearly a quarter to one-third of our workforce, mainly consisting of laboratory
employees, have periodically worked in rotating teams to ensure on the continuation of essential experiments. Our

52

Farmington, CT research site, co-located with the University of Connecticut, has resumed activity at a fifty percent rate after
having paused activity during the state mandated lock down orders previously in effect, however, we have transitioned key
experiments to our offices in Woburn, MA and third parties and contract research organizations have been engaged to
advance certain projects. We have also taken steps consistent with the FDA’s updated industry guidance for conducting
clinical trials.

It is unknown how long these conditions will last and what the complete effect will be to the Company. If COVID-19
continues to spread in the United States and worldwide, and measures to mitigate the ongoing effects of the pandemic, such
as stay home orders and/or advisories persist or are reintroduced, we may continue to experience disruptions and other effects
on our business that could severely impact our business, operations, preclinical studies and clinical trials, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

delays, difficulties or postponement in enrolling and retaining patients in our clinical trials;

delays, difficulties or postponement in clinical site initiation, including difficulties in recruiting clinical site
investigators and clinical site staff;

diversion of healthcare resources away from the conduct of clinical trials, including the diversion of ENT
practices and academic centers serving as our clinical trial sites and staff supporting the conduct of our clinical
trials;

interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel
imposed or recommended by federal or state governments, employers and others or interruption of clinical trial
subject visits and study procedures, which may impact the integrity of subject data and clinical study endpoints;

interruption or delays in the operations of the FDA or other regulatory authorities, which may impact review and
approval timelines;

interruption of, or delays in receiving, supplies of our product candidates from our contract manufacturing
organizations due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems;

interruptions in planned trials due to restricted or limited operations at our laboratory facility;

continual changes to operating requirements and related expenses, limitations in employee resources that would
otherwise be focused on the conduct of our preclinical studies and clinical trials, including because of sickness of
employees or their families or the desire of employees to avoid contact with large groups of people and resulting
losses of productivity and employee work culture;

risk that participants enrolled in our clinical trials will acquire COVID-19 while the clinical trial is ongoing,
which could impact the results of the clinical trial, including by increasing the number of observed adverse
events;

refusal of the FDA, or other government agencies, to accept data from clinical trials in these affected
geographies;

interruption or delayed to our sourced discovery and clinical activities;

inability to obtain additional financing or access the financial markets, and

if any of the CMOs involved in the manufacture and supply of FX-322 experience a delay or disruption due to
COVID-19, we may not have sufficient quantities of FX-322 for our planned activities and may not be able to
transition to a new CMO in a timely or cost-effective manner, or at all, which would negatively impact our
ability to develop and potentially commercialize FX-322.

The global outbreak of COVID-19 continues to rapidly evolve and continues to have indeterminable adverse effects on
general commercial activity and the world economy. We had previously observed an impact from COVID-19 as a number of
clinical trial sites had informed us that they have temporarily halted enrollment, though we completed enrollment on the
Phase 2a clinical trial in September 2020. However, due to the uncertain nature of the effects of the outbreak, particularly in
the United States, enrollment, participation and retention in our ongoing and planned trials may be reduced, and for a number
of the clinical sites, halted for an unknown period of time. Any reduction in enrollment, participation and retention and any
halts may delay our ongoing and planned clinical trials and our development plans for FX-322, which could have an adverse
impact on our business and results of operations.

53

The extent to which COVID-19 may continue to impact our business, preclinical studies, clinical trials (including the
completion and timing of our Phase 2a clinical trial and Phase 1b clinical trials in ARHL and severe SNHL) and operations
will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the
ongoing and ultimate geographic spread of the disease, duration of the outbreak, including future waves of infection, new
variant strains of the underlying virus, travel restrictions and social distancing in the United States and other countries,
business closures or business disruptions, availability and effectiveness of vaccines and the effectiveness of actions taken in
the United States and other countries to contain, treat and mitigate the spread of COVID-19. In addition, if we or any of the
third parties with whom we engage were to experience shutdowns or additional business disruptions, our ability to conduct
our business in the manner and on the timelines presently planned could be materially and negatively impacted, which could
have a material adverse effect on our business and our financial results. The COVID-19 pandemic has resulted in a
widespread health crisis that has adversely affected the economies and financial markets worldwide, resulting in an economic
downturn that could continue to significantly impact our business, financial condition and results of operations. To the extent
the COVID-19 pandemic adversely affects our business, financial condition and results of operations, it may also have the
effect of heightening many of the other risks described in this “Risk Factors” section.

Risks related to commercialization

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

The biotechnology, pharmaceutical, and medical device industries are highly competitive and subject to significant and

rapid technological change. Our success is highly dependent on our ability to acquire, develop, and obtain marketing
approval for new products on a cost-effective basis and to market them successfully. If a product candidate we develop is
approved, we will face intense competition from a variety of businesses, including large, fully integrated pharmaceutical
companies, specialty pharmaceutical companies, and early-stage companies, particularly if the early-stage company has a
collaborative arrangement with a large and established company. We are aware of several companies developing products to
treat SNHL through the regeneration of hair cells or through other mechanisms, and we also anticipate that new companies
will enter the SNHL market in the future. If we successfully develop and, if approved, commercialize FX-322 for the
treatment of SNHL, it may compete, or potentially be used in conjunction, with currently marketed devices, including the
hearing aids and cochlear implants currently available and the next generation of improved hearing aids and cochlear
implants, and any new therapies that may become available in the future. Furthermore, changes in the regulatory landscape
may increase competition from hearing aids. The FDA Reauthorization Act of 2017 created a new category of over-the-
counter, or OTC, hearing aids which are intended to be available to consumers without first requiring a visit to a medical
professional. While the final regulations needed to implement this new category of devices have not yet been issued, if and
when they are, obtaining hearing aids may become less expensive and more convenient.

Competition could render any product candidate we develop obsolete, less competitive, or uneconomical. Our

competitors may, among other things:

•

•

•

•

•

•

•

•

have significantly greater name recognition and financial, manufacturing, marketing, product development,
technical, and human resources than we do, with mergers and acquisitions in the biotechnology, pharmaceutical,
and medical device industries resulting in even more resources being concentrated in our competitors;

more effectively recruit and retain qualified scientific and management personnel;

more effectively establish clinical trial sites and patient registration;

develop and commercialize products that are safer, more effective, less expensive, more convenient, or easier to
administer, or have fewer or less severe side effects;

obtain quicker regulatory approval;

better protect their patents and intellectual property or acquire technologies that are complementary to, or
necessary for, our programs;

implement more effective approaches to sales, marketing, pricing, coverage, and reimbursement; or

form more advantageous strategic alliances or collaborations.

If we are not able to effectively compete for any of the foregoing reasons, our business will be materially harmed.

54

The successful commercialization of any product candidate we develop will depend in part on the extent to which
governmental authorities and health insurers establish adequate coverage, reimbursement levels, and pricing policies.
Failure to obtain or maintain coverage and adequate reimbursement for our product candidates, if approved, could limit
our or our collaborators’ ability to market those products and decrease our or our collaborators’ ability to generate
revenue.

The availability and adequacy of coverage and reimbursement by governmental healthcare programs such as Medicare

and Medicaid, private health insurers, and other third-party payors are essential for most patients to be able to afford
prescription medications. Our ability to achieve acceptable levels of coverage and reimbursement for products or procedures
using our products by governmental authorities, private health insurers and other organizations will influence our ability to
successfully commercialize any product candidates we develop. Obtaining adequate coverage and reimbursement for any
product candidate we develop that is administered under the supervision of a physician, which is what we anticipate for FX-
322, may be particularly difficult because of the higher prices associated with such products. In addition, we believe that FX-
322 is a novel approach to treating hearing loss and, as a result, availability of coverage and reimbursement by payors is
highly uncertain, particularly because the cost of existing treatments for SNHL, such as hearing aids, are generally not
reimbursed by payors. A decision by a third-party payor not to cover or separately reimburse for our products or procedures
using our products could reduce physician utilization of our products once approved. Assuming we obtain coverage for our
product candidates or procedures using our products by a third-party payor, the resulting reimbursement payment rates may
not be adequate or may require co-payments that patients find unacceptably high. We cannot be sure that coverage and
reimbursement in the United States or elsewhere will be available for any product we commercialize, and any reimbursement
that may become available may be decreased or eliminated in the future.

Third-party payors increasingly are challenging prices charged for pharmaceutical products and services, and the
current presidential administration and Congress have introduced several proposals related to drug pricing. Many third-party
payors may refuse to provide coverage and reimbursement for particular drugs or biologics when an equivalent generic drug,
biosimilar, or a less expensive therapy is available. Although there are currently no FDA approved drugs for the treatment of
SNHL, it is possible that a third-party payor may consider FX-322 as substitutable and only offer to reimburse patients for
the less expensive product. Even if we show improved efficacy, pricing of existing drugs and medical devices, such as
hearing aids, may limit the amount we will be able to charge for any product we commercialize. Payors may deny or revoke
the reimbursement status of a given product or establish prices for new or existing marketed products at levels that are too
low to enable us to realize a satisfactory return on our investment in our product candidates. If reimbursement is not available
or is available only at limited levels, we may not be able to successfully commercialize our product candidates and may not
be able to obtain a satisfactory financial return on our product candidates. Additionally, our ability to obtain a satisfactory
financial return depends on what, if any, proposals related to drug pricing may be implemented and, if implemented, when
they might take effect.

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

the United States, third-party payors, including private and governmental payors, such as the Medicare and Medicaid
programs, play an important role in determining the extent to which new drugs and biologics will be covered. The Medicare
and Medicaid programs increasingly are used as models in the United States for how private payors and other governmental
payors develop their coverage and reimbursement policies for drugs and biologics. Some third-party payors may require pre-
approval of coverage for new or innovative devices or drug therapies before they will reimburse healthcare providers who use
such therapies. It is difficult to predict at this time what third-party payors will decide with respect to the coverage and
reimbursement for our product candidates.

No uniform policy for coverage and reimbursement for products exists among third-party payors in the United States.

Therefore, coverage and reimbursement for products can differ significantly from payor to payor, and one third-party payor’s
decision to cover a product does not ensure that other payors will also provide similar coverage. Additionally, the process for
determining whether a third-party payor will provide coverage for a product is typically separate from the process for setting
the price of such product or establishing the reimbursement rate that the payor will pay for the product once coverage is
approved. As a result, the determination of coverage and reimbursement is often a time-consuming and costly process that
will require us to provide scientific and clinical support for the use of our product candidates to each payor separately, with
no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.
Furthermore, rules and regulations regarding reimbursement change frequently, in some cases at short notice, and we believe
that changes in these rules and regulations are likely.

Moreover, increasing efforts by governmental and third-party payors in the United States to cap or reduce healthcare
costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved products and,
as a result, they may not cover or provide adequate payment for any product we commercialize. We expect to experience

55

pricing pressures in connection with the sale of our product candidates due to the trend toward managed health care, the
increasing influence of health maintenance organizations, and additional legislative, administrative, or regulatory changes.
The downward pressure on healthcare costs in general, particularly prescription drugs and biologics and surgical procedures
and other treatments, has become intense. As a result, increasingly high barriers are being erected to the entry of new
products.

We or our collaborators may also be subject to extensive governmental price controls and other market regulations

outside of the United States, and we believe the increasing emphasis on cost-containment initiatives in other countries have
and will continue to put pressure on the pricing and usage of medical products. In many countries, the prices of medical
products are subject to varying price control mechanisms as part of national health systems. Other countries allow companies
to fix their own prices for medical products but monitor and control company profits. Additional foreign price controls or
other changes in pricing regulation could restrict the amount that we or our collaborators are able to charge for products we or
our collaborators commercialize. Accordingly, in markets outside the United States, the reimbursement for products we or
our collaborators commercialize may be reduced compared with the United States and may be insufficient to generate
commercially reasonable revenue and profits.

Even if a product candidate we develop receives marketing approval, it may fail to achieve market acceptance by
physicians, patients, third-party payors, or others in the medical community necessary for commercial success.

If a product candidate we develop receives marketing approval, it may nonetheless fail to gain sufficient market
acceptance by physicians, patients, third-party payors, and others in the medical community. If it does not achieve an
adequate level of acceptance, we may not generate significant product revenues or become profitable. The degree of market
acceptance of our product candidates, if approved, will depend on several factors, including, but not limited to:

•

•

•

•

•

•

•

•

•

•

the efficacy and potential advantages compared to alternative treatments;

effectiveness of sales and marketing efforts;

the cost of treatment in relation to alternative treatments, including any similar generic treatments;

our ability to offer our products for sale at competitive prices;

the convenience and ease of administration compared to alternative treatments;

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

the strength of marketing and distribution support;

the availability of third-party coverage and adequate reimbursement;

the prevalence and severity of any side effects; and

any restrictions on the use of our product together with other medications.

Because we expect sales of our product candidates, if approved, to generate substantially all our revenues for the
foreseeable future, the failure of our product candidates to find market acceptance would harm our business and could require
us to seek additional financing.

If we are unable to establish sales and marketing capabilities either on our own or in collaboration with third parties, we
may not be successful in commercializing any product candidate we develop, if approved.

In order to market and successfully commercialize any product candidate we develop, if approved, we must build our
sales and marketing capabilities or enter into collaborations with third parties for these services. We currently have no sales,
marketing or distribution capabilities and as a company have no experience in marketing products. We intend to directly
market and commercialize FX-322 for the treatment of SNHL, if approved, in the United States by developing our own sales
and marketing force, targeting ear, nose, and throat doctors and audiologists. There are significant expenses and risks
involved with establishing our own sales and marketing capabilities, including our ability to hire, train, retain, and
appropriately incentivize a sufficient number of qualified individuals, generate sufficient sales leads and provide our sales
and marketing team with adequate access to physicians who may prescribe our product, effectively manage a geographically
dispersed sales and marketing team, and other unforeseen costs and expenses. Any failure or delay in the development of a
product candidate that affects the expected timing of commercialization of the product candidate or results in the failure of
the product candidate to be commercialized could result in us having prematurely or unnecessarily incurred costly

56

commercialization expenses. Our investment would be lost if we are unable to retain or reposition our sales and marketing
personnel.

We may also enter into collaborations for the sales and marketing of our product candidates, if approved. To the extent
that we depend on collaborators for sales and marketing activities, any revenues we receive will depend upon the success of
those collaborators’ sales and marketing teams and the collaborators’ prioritization of our product and compliance with
applicable regulatory requirements, and there can be no assurance that the collaborators’ efforts will be successful. For
example, under the License and Collaboration Agreement with Astellas, or the Astellas Agreement, we will depend on
Astellas to sell and market FX-322 for the treatment of SNHL, if approved, outside of the United States, and we can have no
assurance that it will be successful in its efforts or devote sufficient resources to the sale and marketing of FX-322.

If we are unable to build our own sales and marketing team or enter into a collaboration for the commercialization of
product candidates we develop, if approved, we may be forced to delay the commercialization of our product candidates or
reduce the scope of our sales or marketing activities, which would have an adverse effect on our business, operating results
and prospects.

A variety of risks associated with operating internationally could materially adversely affect our business.

Our business strategy includes potentially expanding internationally if any of our product candidates receive regulatory

approval. Doing business internationally involves several risks, including, but not limited to:

•

•

•

•

•

•

•

•

•

•

•

multiple, conflicting, and changing laws and regulations, such as data privacy and security laws and regulations,
tax laws, export and import restrictions, economic sanctions laws and regulations, employment laws, regulatory
requirements, and other governmental approvals, permits, and licenses;

failure by us to obtain and maintain regulatory approvals for the use of our products in various countries;

additional potentially relevant third-party patent rights;

complexities and difficulties in obtaining protection and enforcing our intellectual property;

difficulties in staffing and managing foreign operations;

complexities associated with managing multiple payor reimbursement regimes, government payors, or patient
self-pay systems;

limits in our ability to penetrate international markets;

financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and
regional financial crises on demand and payment for our products, and exposure to foreign currency exchange
rate fluctuations;

natural disasters, political and economic instability, including wars, terrorism and political unrest, outbreak of
disease, boycotts, curtailment of trade, and other business restrictions;

certain expenses, including, among others, expenses for travel, translation, and insurance; and

regulatory and compliance risks that relate to maintaining accurate information and control over sales and
activities that may fall within the purview of the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the
FCPA, its books and records provisions, or its anti-bribery provisions, as well as other applicable laws and
regulations prohibiting bribery and corruption.

Any of these factors could significantly harm any future international expansion and operations and, consequently, our

results of operations.

57

Risks related to our dependence on third parties

The Astellas Agreement is important to our business. If we or Astellas fail to adequately perform under the Astellas
Agreement, or if we or Astellas terminate the Astellas Agreement, the development and commercialization of FX-322 for
SNHL outside the United States would be materially delayed and our business would be adversely affected.

Under the Astellas Agreement, Astellas is responsible for the development and commercialization of FX-322 outside of

the United States and we are responsible for development and commercialization in the United States. We and Astellas are
jointly responsible for conducting global clinical studies and coordinating commercial launch activities.

We have received an upfront payment from Astellas of $80.0 million, and we may also receive development milestone
payments up to $230.0 million. If the Astellas licensed products are successfully commercialized, we would be eligible for up
to $315.0 million in potential commercial milestone payments plus tiered royalties at rates ranging from low- to mid-teen
percentages.

Termination of the Astellas Agreement could cause significant delays in our development and commercialization
efforts for FX-322 for the treatment of SNHL outside of the United States. If the Astellas Agreement is terminated, we would
need to expand our internal capabilities or enter into another agreement to compensate for the loss in funding and clinical
development support from Astellas. Any suitable alternative agreement would take considerable time to negotiate and could
also be on less favorable terms to us. Whether or not we identify another suitable collaborator, we may need to seek
additional financing to continue the development of FX-322, or we may be forced to discontinue development of FX-322,
either of which could have a material adverse effect on our business.

We intend to continue to collaborate with third parties for the development and commercialization of our product
candidates. We may not succeed in establishing and maintaining collaborations, which may significantly limit our ability
to successfully develop and commercialize our other product candidates, if at all.

We have entered into the Astellas Agreement for the development and commercialization of FX-322 for the treatment
of SNHL outside the United States and may seek collaborations for the development and commercialization of other product
candidates. The process of establishing and maintaining collaborative relationships is difficult, time-consuming, and involves
significant uncertainty, such as:

•

•

•

•

•

•

•

•

•

•

•

•

a collaborator may shift its priorities and resources away from our product candidates due to a change in business
strategies, or a merger, acquisition, sale, or downsizing;

a collaborator may seek to renegotiate or terminate its relationships with us due to unsatisfactory clinical results,
manufacturing issues, a change in business strategy, a change of control or other reasons;

a collaborator may cease development in therapeutic areas which are the subject of our collaboration;

a collaborator may not devote sufficient capital or resources towards our product candidates, or may fail to
comply with applicable regulatory requirements;

a collaborator may change the success criteria for a product candidate, thereby delaying or ceasing development
of such candidate;

a significant delay in initiation of certain development activities by a collaborator will also delay payment of
milestones tied to such activities, thereby impacting our ability to fund our own activities;

a collaborator could develop a product that competes, either directly or indirectly, with our product candidate;

a collaborator with commercialization obligations may not commit sufficient financial resources or personnel to
the marketing, distribution, or sale of a product;

a collaborator with manufacturing responsibilities may encounter regulatory, resource, or quality issues and be
unable to meet demand requirements;

a collaborator may terminate a strategic alliance;

a dispute may arise between us and a collaborator concerning the research, development, or commercialization of
a product candidate resulting in a delay in milestones or royalty payments or termination of the relationship and
possibly resulting in costly litigation or arbitration, which may divert management’s attention and resources; and

a collaborator may use our products or technology in such a way as to invite litigation from a third party.

58

If any collaborator fails to fulfill its responsibilities in a timely manner, or at all, our research, clinical development,

manufacturing, or commercialization efforts related to that collaboration could be delayed or terminated, or it may be
necessary for us to assume responsibility for expenses or activities that would otherwise have been the responsibility of our
collaborator. If we are unable to establish and maintain collaborations on acceptable terms or to successfully transition away
from terminated collaborations, we may have to delay or discontinue further development of one or more of our product
candidates, undertake development and commercialization activities at our own expense, or find alternative sources of
capital, which would have a material adverse impact on our clinical development plans and business.

Our employees and independent contractors, including principal investigators, CROs, consultants, vendors, and any third
parties we may engage in connection with development and commercialization may engage in misconduct or other
improper activities, including noncompliance with regulatory standards and requirements, which could have a material
adverse effect on our business.

Our employees and independent contractors, including principal investigators, CROs, consultants, vendors, and any

third parties we may engage in connection with development and commercialization of our product candidates, could engage
in misconduct, including intentional, reckless, or negligent conduct or unauthorized activities that violate applicable laws,
rules, and regulations including: the laws and regulations of the FDA or other similar regulatory requirements of other
authorities, including those laws that require the reporting of true, complete, and accurate information to such authorities;
manufacturing standards; data privacy, security, fraud and abuse, and other healthcare laws and regulations; or laws that
require the reporting of true, complete, and accurate financial information and data. Specifically, sales, marketing, and
business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud,
misconduct, kickbacks, self-dealing, and other abusive practices. These laws and regulations may restrict or prohibit a wide
range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs, and other business
arrangements. Activities subject to these or other laws could also involve the improper use or misrepresentation of
information obtained in the course of clinical trials, creation of fraudulent data in preclinical studies or clinical trials, or
illegal misappropriation of drug product, which could result in regulatory sanctions and cause serious harm to our reputation.
It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to
detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us
from governmental investigations or other actions or lawsuits stemming from a failure to comply with such laws or
regulations. Additionally, we are subject to the risk that a person or government agency could allege such fraud or other
misconduct, even if none occurred. If any such actions are instituted against us or them and we are not successful in
defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of
operations, including the imposition of significant civil, criminal, and administrative penalties, damages, monetary fines,
possible exclusion from participation in Medicare, Medicaid, other U.S. federal healthcare programs or healthcare programs
in other jurisdictions, individual imprisonment, other sanctions, contractual damages, reputational harm, diminished profits
and future earnings, and curtailment of our operations.

We currently rely on third-party contract manufacturing organizations, or CMOs, for the production of clinical supply of
FX-322 and intend to rely on CMOs for the production of commercial supply of FX-322, if approved, and for clinical and
commercial supply of our future product candidates, as well as to supply raw materials necessary to produce our product
candidates. Our dependence on CMOs may impair the development of our product candidates and may impair their
commercialization, which would adversely impact our business and financial position.

We do not own facilities for manufacturing FX-322 or any product candidate. Instead, we rely on and expect to
continue to rely on CMOs for the supply of cGMP grade clinical trial materials of FX-322 and any product candidates we
develop and, in future, for commercial quantities. Reliance on CMOs may expose us to more risk than if we were to
manufacture our product candidates ourselves. If any CMO we engage is unable to provide sufficient supply of any product
candidate we develop, we may be unable to arrange for an alternative supply or to do so on commercially reasonable terms or
in a timely manner, which could delay any clinical trials, the commercial launch of our product candidates, if approved, or,
regarding any commercial supply, result in a shortage in supply that could negatively impact our revenues. For example, we
are substantially dependent on the CMO that supplies us with the proprietary glycogen synthase kinase 3, or GSK3, inhibitor
that is a key component of FX-322 and the CMO that lyophilizes FX-322 into a powder. While there are other CMOs who
are able to supply the GSK3 inhibitor or lyophilize FX-322, manufacture of the GSK3 inhibitor and the lyophilization
process require proprietary knowledge or specialized capabilities that only a limited number of CMOs have. As a result,
transitioning to a new CMO for either the supply of the GSK3 inhibitor or to conduct the lyophilization process would be
particularly time consuming and costly. We have just begun to engage other CMOs as back-up for the manufacture and
supply of FX-322. As a result, if any of the CMOs involved in the manufacture and supply of FX-322 experience a delay or
disruption, or if we fail to obtain the appropriate approvals to manufacture and supply FX-322 outside the US (e.g., as a result

59

of a failure to obtain a waiver under the Bayh-Dole Act), we may not have sufficient quantities of FX-322 for our planned
activities and may not be able to transition to a new CMO in a timely or cost-effective manner, or at all, which would
negatively impact our ability to develop and potentially commercialize FX-322.

The facilities used to manufacture our product candidates must be inspected by the FDA and comparable foreign
regulatory authorities. While we provide oversight of manufacturing activities, we do not and will not control the execution
of manufacturing activities by, and are or will be dependent on, our CMOs for compliance with cGMP requirements for the
manufacture of our product candidates. As a result, we are subject to the risk that our product candidates may have
manufacturing defects that we have limited ability to prevent. If a CMO cannot successfully manufacture material that
conforms to our specifications and the regulatory requirements, we will not be able to secure or maintain regulatory approval
for the use of our product candidates in clinical trials, or for commercial distribution of our product candidates, if approved.
While we have engaged independent auditors to assess the compliance with the protocol that we co-developed with our
CMOs regarding the manufacturing process for FX-322, in general, we have limited control over the ability of our CMOs to
maintain adequate quality control, quality assurance, and qualified personnel, and we were not involved in developing our
CMOs’ policies and procedures.

If the FDA or comparable foreign regulatory authority finds deficiencies with or does not approve these facilities for
the manufacture of our product candidates or if it withdraws any such approval or finds deficiencies in the future, we may
need to find alternative manufacturing facilities, which would delay our development program and significantly impact our
ability to develop, obtain regulatory approval for, or commercialize our product candidates, if approved. In addition, any
failure to achieve and maintain compliance with laws, regulations, and standards related to manufacturing could subject us to
risks, including the risk that we may have to suspend the manufacture of our product candidates, that obtained approvals
could be revoked, and that the FDA or another governmental regulatory authority may take enforcement actions, including
untitled letters, warning letters, seizures, injunctions, or product recalls. Furthermore, CMOs may breach existing agreements
they have with us because of factors beyond our control. They may also terminate or refuse to renew their agreement at a
time that is costly or otherwise inconvenient for us. If we were unable to find an adequate CMO or another acceptable
solution in time, our clinical trials could be delayed, or our commercial activities could be harmed.

We contract for the supply of the active pharmaceutical ingredient, or API, and other raw material necessary to produce

FX-322 and we may contract in the future for the supply of API and other raw material for any other product candidate we
develop. Supplies of API or other raw material could be interrupted from time to time and we cannot be certain that
alternative supplies could be obtained within a reasonable time frame, at an acceptable cost, or at all. The extent to which the
COVID-19 pandemic impacts our ability to procure sufficient supplies for the development of our products and product
candidates will depend on the severity and duration of the spread of the virus, and the actions undertaken to mitigate the
spread of COVID-19 or treat its effects and may cause delays. In addition, a disruption in the supply of API or other raw
material could delay the commercial launch of our product candidates, if approved, or result in a shortage in supply, which
would impair our ability to generate revenues. Growth in the costs and expenses of API or other raw material may also impair
our ability to cost-effectively manufacture our product candidates. In addition, there may be a limited number of suppliers for
API or other raw material that we may use to manufacture our product candidates, and we cannot be certain that we will be
able to engage such suppliers in a timely manner or at all. If we are unable to do so, clinical development of our product
candidates, commercialization for any approved product, or our business could be adversely affected.

Finding new CMOs or third-party suppliers involves additional cost and requires our management’s time and focus. In
addition, there is typically a transition period when a new CMO commences work. Although we have not, and do not intend
to, begin a clinical trial unless we believe we have on hand, or will be able to obtain, a sufficient supply of our product
candidates to complete the clinical trial, any significant delay in the supply of our product candidates or the raw materials
needed to produce our product candidates, could considerably delay conducting our clinical trials and potential regulatory
approval of our product candidates.

As part of their manufacture of our product candidates, our CMOs and third-party suppliers are expected to comply

with and respect the proprietary rights of others. If a CMO or third-party supplier fails to acquire the proper licenses or
otherwise infringes the proprietary rights of others in the course of providing services to us, we may have to find alternative
CMOs or third-party suppliers or defend against claims of infringement, either of which would significantly impact our
ability to develop, obtain regulatory approval for, or commercialize our product candidates, if approved.

60

We intend to rely on third parties to conduct, supervise, and monitor our clinical trials. If those third parties do not
successfully carry out their contractual duties, or if they perform in an unsatisfactory manner, it may harm our business.

We rely, and will continue to rely, on CROs, CRO-contracted vendors, and clinical trial sites to ensure the proper and
timely conduct of our clinical trials, including our Phase 2a trial and other ongoing and planned clinical trials of FX-322 for
the treatment of SNHL. Our reliance on CROs for clinical development activities limits our control over these activities and
we were not involved in developing our CRO’s policies and procedures, but we remain responsible for ensuring that each of
our trials is conducted in accordance with the applicable protocol and legal, regulatory, and scientific standards.

We and our CROs will be required to comply with the Good Laboratory Practice requirements for our preclinical
studies and GCP requirements for our clinical trials, which are regulations and guidelines enforced by the FDA and are also
required by comparable foreign regulatory authorities. Regulatory authorities enforce GCP requirements through periodic
inspections of trial sponsors, principal investigators, and clinical trial sites. If we or our CROs fail to comply with GCP
requirements, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign
regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We
cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of
our clinical trials comply with GCP requirements. In addition, our clinical trials must be conducted with product produced
under cGMP requirements. Accordingly, if our CROs fail to comply with these requirements, we may be required to repeat
clinical trials, which would delay the regulatory approval process.

Our CROs are not our employees, and we do not control whether they devote sufficient time and resources to our

clinical trials. Our CROs may also have relationships with other commercial entities, including our competitors, for whom
they may also be conducting clinical trials, or other drug development activities, which could harm our competitive position.
We face the risk of potential unauthorized disclosure or misappropriation of our intellectual property by CROs, which may
reduce our trade secret protection and allow our potential competitors to access and exploit our proprietary technology. If our
CROs do not successfully carry out their contractual duties or obligations, or fail to meet expected deadlines, or if the quality
or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory
requirements or for any other reason, our clinical trials may be extended, delayed or terminated, and we may not be able to
obtain regulatory approval for, or successfully commercialize, any product candidate that we develop. As a result, our
financial results and the commercial prospects for any product candidate that we develop would be harmed, our costs could
increase, and our ability to generate revenue could be delayed.

If our relationship with any CROs terminates, we may not be able to enter into arrangements with alternative CROs or

do so on commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires
management’s time and focus. In addition, there is a natural transition period when a new CRO commences work. As a
result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. While the
COVID-19 pandemic and government measures taken in response have had a significant impact on our CROs and their
ability to conduct clinical trials, there is potential they will face disruption in the future, which may affect our ability to
initiate and complete our clinical trials. Though we intend to carefully manage our relationships with our CROs, there can be
no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not have an
adverse impact on our business, financial condition, and prospects.

Risks related to healthcare laws and other legal compliance matters

Enacted and future healthcare legislation may increase the difficulty and cost for us to obtain marketing approval of and
commercialize our product candidates, if approved, and may affect the prices we may set.

In the United States and other jurisdictions, there have been, and we expect there will continue to be, a number of
legislative and regulatory changes, and additional proposed changes, to the healthcare system that could affect our future
results of operations. In particular, there have been and continue to be a number of initiatives at the U.S. federal and state
levels that seek to reduce healthcare costs and improve the quality of health care. For example, in March 2010, the Patient
Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the
ACA, was enacted, which substantially changed the way healthcare is financed by both governmental and private insurers.
Among the provisions of the ACA, those of greatest importance to the biotechnology and pharmaceutical industries include
the following:

•

•

an annual, non-deductible fee payable by any entity that manufactures or imports certain branded prescription
drugs and biologic agents;

an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program;

61

•

•

•

a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are
calculated for drugs and biologics that are inhaled, infused, instilled, implanted, or injected;

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative
clinical effectiveness research, along with funding for such research; and

establishment of a Center for Medicare Innovation at the Centers for Medicare & Medicaid Services, or CMS, to
test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially
including prescription drug spending.

Since its enactment, there have been judicial challenges to certain aspects of the ACA, and we expect there will be

additional challenges to the ACA in the future. For example, in December 2018, a U.S. District Court judge in the Northern
District of Texas ruled that the individual mandate is a critical and inseverable feature of the ACA, and therefore, because it
was modified as part of the TCJA, the remaining provisions of the ACA are invalid as well. On December 18, 2019, the U.S.
Court of Appeals for the 5th Circuit upheld the district court’s decision that the individual mandate was unconstitutional but
remanded the case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well.
The U.S. Supreme Court is currently reviewing this case, although it is unclear when or how the Supreme Court will rule. It
is also unclear how other efforts, if any, to challenge, repeal or amend some or all aspects of the ACA will impact the law,
our business or financial condition.

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For

example, the Budget Control Act of 2011 resulted in aggregate reductions of Medicare payments to providers of 2% per
fiscal year. These reductions went into effect in April 2013 and, due to subsequent legislative amendments to the statute, will
remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020 through March 31, 2021,
unless additional action is taken by Congress. In addition, in January 2013, the American Taxpayer Relief Act of 2012 was
signed into law, which, among other things, further reduced Medicare payments to several types of providers, including
hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to
recover overpayments to providers from three to five years. These new laws or any other similar laws introduced in the future
may result in additional reductions in Medicare and other healthcare funding, which could negatively affect our potential
customers and accordingly, our financial operations.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to
specialty drug pricing practices. Specifically, there have been administration efforts, Congressional inquiries and proposed
federal and state legislation designed to bring more transparency to drug pricing, reduce the cost of prescription drugs under
Medicare, review the relationship between pricing and manufacturer patient assistance programs and reform government
program reimbursement methodologies for drugs. Moreover, payment methodologies may be subject to changes in healthcare
legislation and regulatory initiatives. We expect that additional U.S. federal healthcare reform measures will be implemented
in the future, any of which could limit the amounts that the U.S. federal government will pay for healthcare products and
services, which could result in reduced demand for our product candidates or additional pricing pressures.

Individual states in the United States have also become increasingly active in passing legislation and implementing

regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement
constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in
some cases, measures designed to encourage importation from other countries and bulk purchasing. Legally mandated price
controls on payment amounts by third-party payors or other restrictions could harm our business, results of operations,
financial condition, and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using
bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug
and other healthcare programs. Furthermore, there has been increased interest by third-party payors and governmental
authorities in reference pricing systems and publication of discounts and list prices. These reforms could reduce the ultimate
demand for our product candidates or put pressure on our product pricing.

In markets outside of the United States, reimbursement and healthcare payment systems vary significantly by country,

and many countries have instituted price ceilings on specific products and therapies. We cannot predict the likelihood, nature,
or extent of government regulation that may arise from future legislation or administrative action in the United States or any
other jurisdiction. If we or any third parties we may engage are slow or unable to adapt to changes in existing requirements or
the adoption of new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance,
our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain
profitability.

Our business operations and current and future relationships with contractors, investigators, healthcare professionals,
consultants, third-party payors, patient organizations, customers, and others will be subject to applicable healthcare
regulatory laws, which could expose us to penalties.

Our business operations and current and future arrangements with contractors, investigators, healthcare professionals,

consultants, third-party payors, patient organizations, and customers may expose us to broadly applicable fraud and abuse
and other healthcare laws and regulations. These laws may constrain the business or financial arrangements and relationships
through which we conduct our operations, including how we research, market, sell, and distribute our product candidates, if
approved. Such laws include:

•

•

•

•

•

•

•

•

the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly
and willfully soliciting, offering, receiving, or providing any remuneration (including any kickback, bribe, or
certain rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward, or in return for,
either the referral of an individual for, or the purchase, lease, order, or recommendation of, any good, facility, item
or service for which payment may be made, in whole or in part, under U.S. federal and state healthcare programs
such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the statute or
specific intent to violate it in order to have committed a violation. The U.S. federal Anti-Kickback Statute has been
interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers,
purchasers and formulary managers on the other hand;

the U.S. federal false claims, including the civil False Claims Act, or FCA, which, among other things, impose
criminal and civil penalties, including through civil whistleblower or qui tam actions, against individuals or
entities for knowingly presenting, or causing to be presented, to the U.S. federal government claims for payment
or approval that are false or fraudulent, knowingly making, using or causing to be made or used a false record or
statement material to a false or fraudulent claim, or from knowingly making a false statement to avoid, decrease
or conceal an obligation to pay money to the U.S. federal government. In addition, the government may assert
that a claim including items and services resulting from a violation of the U.S. federal Anti-Kickback Statute
constitutes a false or fraudulent claim for purposes of the FCA. A claim includes “any request or demand” for
money or property presented to the federal government. In addition, pharmaceutical manufacturers can be held
liable under the FCA even when they do not submit claims directly to government payors if they are deemed to
“cause” the submission of false or fraudulent claims;

the U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal
and civil liability for, among other things, knowingly and willfully executing, or attempting to execute, a scheme
to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or
promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit
program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or
covering up a material fact or making any materially false statement, in connection with the delivery of, or
payment for, healthcare benefits, items or services. Similar to the U.S. federal Anti-Kickback Statute, a person or
entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have
committed a violation:

the FDCA, which prohibits, among other things, the adulteration or misbranding of drugs, biologics, and medical
devices;

federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and
activities that potentially harm consumers;

federal price reporting laws, which require manufacturers to calculate and report complex pricing metrics to
government programs, where such reported prices may be used in the calculation of reimbursement and/or
discounts on approved products;

the U.S. federal legislation commonly referred to as the Physician Payments Sunshine Act, enacted as part of the
ACA, and its implementing regulations, which requires certain manufacturers of drugs, devices, biologics, and
medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program to
report annually to the government information related to certain payments and other transfers of value to
physicians (as defined by statute) and teaching hospitals, as well as ownership and investment interests held by
such physicians and their immediate family members. Beginning in 2022, such obligations will include payments
and other transfers of value provided in the previous year to certain other healthcare professionals, including
physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, anesthesiology
assistants and certified nurse midwives;

analogous U.S. state laws and regulations, including: state anti-kickback and false claims laws, which may apply
to our business practices, including but not limited to, research, distribution, sales, and marketing arrangements

63

and claims involving healthcare items or services reimbursed by any third-party payor, including private insurers;
state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary
compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal government, or
otherwise restrict payments that may be made to healthcare providers and other potential referral sources; and
state laws and regulations that require drug manufacturers to file reports relating to pricing and marketing
information, which requires tracking gifts and other remuneration and items of value provided to healthcare
professionals and entities;

similar healthcare laws and regulations in the European Union, or EU, and other jurisdictions, including reporting
requirements detailing interactions with and payments to healthcare providers; and

laws and regulations prohibiting bribery and corruption such as the FCPA, which, among other things, prohibits
U.S. companies and their employees and agents from authorizing, promising, offering, or providing, directly or
indirectly, corrupt or improper payments or anything else of value to foreign government officials, employees of
public international organizations or foreign government-owned or affiliated entities, candidates for foreign
public office, and foreign political parties or officials thereof.

•

•

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors
available under such laws, it is possible that some of our business activities, including our consulting agreements and other
relationships with healthcare providers, some of whom receive stock or stock options as compensation for their services,
could be subject to challenge under one or more of such laws. Ensuring that our current and future internal operations and
business arrangements with third parties comply with applicable healthcare laws and regulations will involve substantial
costs. It is possible that governmental authorities will conclude that our business practices do not comply with current or
future statutes, regulations, agency guidance, or case law involving applicable fraud and abuse or other healthcare laws and
regulations.

If our operations are found to be in violation of any of the laws described above or any other governmental laws and

regulations that may apply to us, we may be subject to actions including the imposition of civil, criminal, and administrative
penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid, and other
federal healthcare programs, individual imprisonment, contractual damages, reputational harm, diminished profits and future
earnings, additional reporting requirements, or oversight if we become subject to a corporate integrity agreement or similar
agreement to resolve allegations of noncompliance with these laws, and curtailment or restructuring of our operations, any of
which could adversely affect our ability to operate our business and our results of operations. If any of the physicians or other
providers or entities with whom we expect to do business are found to not be in compliance with applicable laws, they may
be subject to criminal, civil or administrative sanctions, including exclusions from government-funded healthcare programs
and imprisonment, which could affect our ability to operate our business. Further, defending against any such actions can be
costly, time consuming, and may require significant personnel resources. Therefore, even if we are successful in defending
against any such actions that may be brought against us, our business may be impaired.

Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards
and other requirements could adversely affect our business, results of operations, and financial condition.

The global data protection landscape is rapidly evolving, and we are or may become subject to numerous state, federal

and foreign laws, requirements and regulations governing the collection, use, disclosure, retention, and security of personal
data, such as information that we may collect in connection with clinical trials in the U.S. and abroad. Implementation
standards and enforcement practices are likely to remain uncertain for the foreseeable future, and we cannot yet determine the
impact future laws, regulations, standards, or perception of their requirements may have on our business. This evolution may
create uncertainty in our business, affect our ability to operate in certain jurisdictions or to collect, store, transfer use and
share personal information, necessitate the acceptance of more onerous obligations in our contracts, result in liability or
impose additional costs on us. The cost of compliance with these laws, regulations and standards is high and is likely to
increase in the future. Any failure or perceived failure by us to comply with federal, state or foreign laws or regulation, our
internal policies and procedures or our contracts governing our processing of personal information could result in negative
publicity, government investigations and enforcement actions, claims by third parties and damage to our reputation, any of
which could have a material adverse effect on our operations, financial performance and business.

As our operations and business grow, we may become subject to or affected by new or additional data protection laws

and regulations and face increased scrutiny or attention from regulatory authorities. In the U.S., HIPAA imposes, among

64

other things, certain standards relating to the privacy, security, transmission and breach reporting of individually identifiable
health information. Certain states have also adopted comparable privacy and security laws and regulations, some of which
may be more stringent than HIPAA. Such laws and regulations will be subject to interpretation by various courts and other
governmental authorities, thus creating potentially complex compliance issues for us and our future customers and strategic
partners. In addition, the CCPA went into effect on January 1, 2020. The CCPA creates individual privacy rights for
California consumers and increases the privacy and security obligations of entities handling certain personal information. The
CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to
increase data breach litigation. The CCPA may increase our compliance costs and potential liability, and many similar laws
have been proposed at the federal level and in other states. Further, the CPRA recently passed in California. The CPRA will
impose additional data protection obligations on covered businesses, including additional consumer rights processes,
limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will
also create a new California data protection agency authorized to issue substantive regulations and could result in increased
privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and
additional compliance investment and potential business process changes may be required. In the event that we are subject to
or affected by HIPAA, the CCPA, the CPRA or other domestic privacy and data protection laws, any liability from failure to
comply with the requirements of these laws could adversely affect our financial condition.

Further, the GDPR applies to companies established in the EEA, as well as to companies that are not established in the
EEA and which collect and use personal data in relation to (i) offering goods or services to, or (ii) monitoring the behavior of,
individuals located in the EEA. If we conduct clinical trial programs in the EEA (whether the trials are conducted directly by
us or through a clinical vendor or collaborator), or enter into research collaborations involving the monitoring of individuals
in the EEA, or market our products to individuals in the EEA, we will be subject to the GDPR. The GDPR puts in place
stringent operational requirements for processors and controllers of personal data, including, for example, high standards for
obtaining consent from individuals to process their personal data (or reliance on another appropriate legal basis), the
provision of robust and detailed disclosures to individuals about how personal data is collected and processed (in a concise,
intelligible and easily accessible form), a comprehensive individual data rights regime (including access, erasure, objection,
restriction, rectification and portability), maintaining a record of data processing, data export restrictions governing transfers
of data from the EEA, short timelines for data breach notifications to be given to data protection regulators or supervisory
authorities (and in certain cases, affected individuals) of significant data breaches, and limitations on retention of information.
The GDPR also puts in place increased requirements pertaining to health data and other special categories of personal data, as
well as a definition of pseudonymized (i.e., key-coded) data. Further, the GDPR provides that EEA member states may
establish their own laws and regulations limiting the processing of genetic, biometric, or health data, which could limit our
ability to collect, use, and share such data and/or could cause our costs to increase. In addition, there are certain obligations if
we contract third-party processors in connection with the processing of personal data. If our or our collaborators’ or service
providers’ privacy or data security measures fail to comply with the GDPR requirements, we may be subject to litigation,
regulatory investigations, enforcement notices requiring us to change the way we use personal data, or fines of up to
20 million Euros or up to 4% of our total worldwide annual revenue of the preceding financial year, whichever is higher, as
well as compensation claims by affected individuals, including class-action type litigation, negative publicity, reputational
harm and a potential loss of business and goodwill. Among other requirements, the GDPR regulates transfers of personal data
subject to the GDPR to third countries that have not been found to provide adequate protection to such personal data,
including the United States, and the efficacy and longevity of current transfer mechanisms between the EU and the United
States remains uncertain. For example, in 2016, the EU and United States agreed to a transfer framework for data transferred
from the EU to the United States, called the Privacy Shield, but the Privacy Shield was invalidated in July 2020 by the Court
of Justice of the European Union. Further, from January 1, 2021, companies have to comply with the GDPR and also the
United Kingdom GDPR, or the UK GDPR, which, together with the amended UK Data Protection Act 2018, retains the
GDPR in UK national law. The UK GDPR mirrors the fines under the GDPR, i.e., fines up to the greater of €20 million
(£17.5 million) or 4% of global turnover. The relationship between the United Kingdom and the European Union in relation
to certain aspects of data protection law remains unclear, and it is unclear how United Kingdom data protection laws and
regulations will develop in the medium to longer term, and how data transfers to and from the United Kingdom will be
regulated in the long term. Currently there is a four to six-month grace period agreed in the EU and United Kingdom Trade
and Cooperation Agreement, ending June 30, 2021 at the latest, whilst the parties discuss an adequacy decision. However, it
is not clear whether (and when) an adequacy decision may be granted by the European Commission enabling data transfers
from EU member states to the United Kingdom long term without additional measures. These changes may lead to additional
costs and increase our overall risk exposure.

65

Although we work to comply with applicable laws, regulations and standards, our contractual obligations and other
legal obligations, these requirements are evolving and may be modified, interpreted and applied in an inconsistent manner
from one jurisdiction to another, and may conflict with one another or other legal obligations with which we must comply.
Any failure or perceived failure by us or our employees, representatives, contractors, consultants, collaborators, or other third
parties to comply with such requirements or adequately address privacy and security concerns, even if unfounded, could
result in additional cost and liability to us, damage our reputation, and adversely affect our business and results of operations.

We are subject to environmental, health and safety laws and regulations, and we may become exposed to liability and
substantial expenses in connection with environmental compliance or remediation activities.

Our operations, including our development, testing and manufacturing activities, are subject to numerous

environmental, health and safety laws and regulations. These laws and regulations govern, among other things, the controlled
use, handling, release, and disposal of and the maintenance of a registry for, hazardous materials and biological materials,
such as chemical solvents, human cells, carcinogenic compounds, mutagenic compounds, and compounds that have a toxic
effect on reproduction, laboratory procedures and exposure to blood-borne pathogens. If we fail to comply with such laws
and regulations, we could be subject to fines or other sanctions.

As with other companies engaged in activities similar to ours, we face a risk of environmental liability inherent in our

current and historical activities, including liability relating to releases of or exposure to hazardous or biological materials.
Environmental, health and safety laws and regulations are becoming more stringent. We may be required to incur substantial
expenses in connection with future environmental compliance or remediation activities, in which case, the production efforts
of our third-party manufacturers or our development efforts may be interrupted or delayed.

Risks related to our intellectual property

If we are unable to obtain, maintain, enforce and protect patent protection for our technology and product candidates or if
the scope of the patent protection obtained is not sufficiently broad, our competitors could develop and commercialize
technology and products similar or identical to ours, and our ability to successfully develop and commercialize our
technology and product candidates may be adversely affected.

Our success depends in large part on our ability to obtain and maintain protection of the intellectual property we may
own solely and jointly with others, or may license from others, particularly patents, in the United States and other countries
with respect to any proprietary technology and product candidates we develop. We seek to protect our proprietary position by
filing patent applications in the United States and abroad related to our technologies and product candidates that are
important to our business and by in-licensing intellectual property related to such technologies and product candidates. If we
are unable to obtain or maintain patent protection with respect to any proprietary technology or product candidate, our
business, financial condition, results of operations and prospects could be materially harmed.

The patent prosecution process is expensive, time-consuming, and complex, and we may not be able to file, prosecute,
maintain, defend, or license all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also
possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain
patent protection. Moreover, in some circumstances, we do not have the right to control the preparation, filing, and
prosecution of patent applications, or to maintain, enforce, and defend the patents, covering technology that we license from
third parties. Therefore, these in-licensed patents, and applications may not be prepared, filed, prosecuted, maintained,
defended, and enforced in a manner consistent with the best interests of our business.

The patent position of pharmaceutical and biotechnology companies generally is highly uncertain, involves complex

legal and factual questions and has in recent years been the subject of much litigation. In addition, the scope of patent
protection outside of the United States is uncertain and laws of foreign countries may not protect our rights to the same extent
as the laws of the United States or vice versa. For example, European patent law restricts the patentability of methods of
treatment of the human body more than U.S. law does. With respect to both owned and in-licensed patent rights, we cannot
predict whether the patent applications we and our licensors are currently pursuing will issue as patents in any particular
jurisdiction or whether the claims of any issued patents will provide sufficient protection from competitors. Further, we may
not be aware of all third-party intellectual property rights potentially relating to our product candidates. In addition,
publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the
United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not published at
all. Therefore, neither we nor our licensors can know with certainty whether either we or our licensors were the first to make
the inventions claimed in the patents and patent applications we own or in-license now or in the future, or that either we or
our licensors were the first to file for patent protection of such inventions. As a result, the issuance, scope, validity,

66

enforceability, and commercial value of our owned and in-licensed patent rights are uncertain. Moreover, our owned and in-
licensed pending and future patent applications may not result in patents being issued that protect our technology and product
candidates, in whole or in part, or that effectively prevent others from commercializing competitive technologies and
products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may
diminish the value of our patents and our ability to obtain, protect, maintain, defend, and enforce our patent rights, narrow the
scope of our patent protection and, more generally, could affect the value or narrow the scope of our patent rights.

Moreover, we or our licensors may be subject to a third-party pre-issuance submission of prior art to the United States

Patent and Trademark Office, or USPTO, or become involved in opposition, derivation, revocation, reexamination, inter
partes review, post-grant review, or interference proceedings challenging our patent rights or the patent rights of others. An
adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent
rights, allow third parties to commercialize our technology or product candidates and compete directly with us, without
payment to us, or result in our inability to manufacture or commercialize drugs without infringing third-party patent rights. If
the breadth or strength of protection provided by our patents and patent applications is threatened, regardless of the outcome,
it could dissuade companies from collaborating with us to license, develop or commercialize current or future product
candidates.

Additionally, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and
its scope can be reinterpreted after issuance. Even if our owned and in-licensed patent applications issue as patents, they may
not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us, or
otherwise provide us with any competitive advantage. The issuance of a patent is not conclusive as to its inventorship, scope,
validity, or enforceability, and our owned and in-licensed patents may be challenged in the courts or patent offices in the
United States and abroad. Such challenges may result in loss of exclusivity or freedom to operate or in patent claims being
narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or
commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology
and product candidates. Such proceedings also may result in substantial cost and require significant time from our
management and employees, even if the eventual outcome is favorable to us. Given the amount of time required for the
development, testing and regulatory review of new product candidates, patents protecting such candidates might expire
before or shortly after such candidates are commercialized. Furthermore, our competitors may be able to circumvent our
owned or in-licensed patents by developing similar or alternative technologies or products in a non-infringing manner. As a
result, our owned and in-licensed patent portfolio may not provide us with sufficient rights to exclude others from
commercializing technology and products similar or identical to any of our technology and product candidates.

Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of
time.

Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a
patent is generally 20 years from its earliest United States non-provisional filing date. Various extensions may be available,
but the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates are obtained,
once the patent life has expired, we may be open to competition from competitive products, including generics or biosimilars.
Given the amount of time required for the development, testing, and regulatory review of new product candidates, patents
protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned
and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products
similar or identical to ours.

If we are unable to obtain licenses from third parties on commercially reasonable terms or fail to comply with our
obligations under such agreements, our business could be harmed.

It may be necessary for us to use the patented or proprietary technology of third parties to commercialize our products,
in which case we would be required to obtain a license from these third parties. If we are unable to license such technology,
or if we are forced to license such technology on unfavorable terms, our business could be materially harmed. If we are
unable to obtain a necessary license, we may be unable to develop or commercialize the affected product candidates, which
could materially harm our business and the third parties owning such intellectual property rights could seek either an
injunction prohibiting our sales or an obligation on our part to pay royalties and/or other forms of compensation. Even if we
are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed
to us.

67

If we are unable to obtain rights to required third-party intellectual property rights or maintain the existing intellectual

property rights we have, we may be required to expend significant time and resources to redesign our technology, product
candidates, or the methods for manufacturing them or to develop or license replacement technology, all of which may not be
feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or commercialize the
affected technology and product candidates, which could significantly harm our business, financial condition, results of
operations, and prospects.

Additionally, if we fail to comply with our obligations under license agreements, our counterparties may have the right

to terminate these agreements, in which event we might not be able to develop, manufacture or market, or may be forced to
cease developing, manufacturing or marketing, any product that is covered by these agreements or may face other penalties
under such agreements. Such an occurrence could materially adversely affect the value of the product candidate being
developed under any such agreement. Termination of these agreements or reduction or elimination of our rights under these
agreements, or restrictions on our ability to freely assign or sublicense our rights under such agreements when it is in the
interest of our business to do so, may result in our having to negotiate new or reinstated agreements with less favorable terms,
cause us to lose our rights under these agreements, including our rights to important intellectual property or technology, or
impede, or delay or prohibit the further development or commercialization of, one or more product candidates that rely on
such agreements.

If we do not obtain patent term extension in the United States under the Hatch-Waxman Act and in foreign countries
under similar legislation, thereby potentially extending the term of our marketing exclusivity for any product candidates
we may develop, our business may be materially harmed.

In the United States, the patent term of a patent that covers an FDA-approved drug may be eligible for limited patent

term extension, which permits patent term restoration as compensation for the patent term lost during the FDA regulatory
review process. The Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman
Act, permits a patent term extension of up to five years beyond the expiration of the patent. The length of the patent term
extension is related to the length of time the drug is under regulatory review. Patent extension cannot extend the remaining
term of a patent beyond a total of 14 years from the date of product approval. In addition, only one patent applicable to an
approved drug may be extended, and only those claims covering the approved drug, a method for using it, or a method for
manufacturing it may be extended. Similar provisions may be available in Europe and certain other non-United States
jurisdictions to extend the term of a patent that covers an approved drug. While, in the future, if and when our product
candidates receive FDA approval, we expect to apply for patent term extensions on patents covering those product
candidates, there is no guarantee that the applicable authorities will agree with our assessment of whether such extensions
should be granted, and even if granted, the length of such extensions. We may not be granted patent term extension either in
the United States or in any foreign country because of, for example, failing to exercise due diligence during the testing phase
or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant
patents, or otherwise failing to satisfy applicable requirements. Moreover, the term of extension, as well as the scope of
patent protection during any such extension, afforded by the governmental authority could be less than we request. If we are
unable to obtain any patent term extension or the term of any such extension is less than we request, our competitors may
obtain approval of competing products following the expiration of our patent rights, and our business, financial condition,
results of operations, and prospects could be materially harmed.

It is possible that we will not obtain patent term extension under the Hatch-Waxman Act for a United States patent
covering any of our product candidates that we may identify even where that patent is eligible for patent term extension, or if
we obtain such an extension, it may be for a shorter period than we had sought. Further, for our licensed patents, we may not
have the right to control prosecution, including filing with the USPTO, of a petition for patent term extension under the
Hatch-Waxman Act. Thus, if one of our licensed patents is eligible for patent term extension under the Hatch-Waxman Act,
we may not be able to control whether a petition to obtain a patent term extension is filed, or obtained, from the USPTO.

Also, there are detailed rules and requirements regarding the patents that may be submitted to the FDA for listing in the

Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book. We may be unable to obtain
patents covering our product candidates that contain one or more claims that satisfy the requirements for listing in the Orange
Book. Even if we submit a patent for listing in the Orange Book, the FDA may decline to list the patent, or a manufacturer of
generic drugs may challenge the listing. If one of our product candidates is approved and a patent covering that product
candidate is not listed in the Orange Book, a manufacturer of generic drugs would not have to provide advance notice to us of
any abbreviated new drug application filed with the FDA to obtain permission to sell a generic version of such product
candidate.

68

Although we or our licensors are not currently involved in any litigation, we may become involved in lawsuits to protect or
enforce our patent or other intellectual property rights, which could be expensive, time-consuming and unsuccessful.

Competitors and other third parties may infringe, misappropriate or otherwise violate our or our licensors’ issued
patents or other intellectual property. As a result, we or our licensors may need to file infringement, misappropriation or other
intellectual property related claims, which can be expensive and time-consuming. Any claims we assert against perceived
infringers could provoke such parties to assert counterclaims against us alleging that we infringe, misappropriate, or
otherwise violate their intellectual property. In addition, in a patent infringement proceeding, such parties could counterclaim
that the patents we or our licensors have asserted are invalid or unenforceable. In patent litigation in the United States,
defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be
an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, or non-enablement.
Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent
withheld relevant information from the USPTO or made a misleading statement during prosecution. Third parties may
institute such claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such
mechanisms include re-examination, post-grant review, inter partes review, interference proceedings, derivation proceedings,
and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). The outcome following legal assertions of
invalidity and unenforceability is unpredictable.

An adverse result in any such proceeding could put one or more of our owned or in-licensed patents at risk of being

invalidated or interpreted narrowly and could put any of our owned or in-licensed patent applications at risk of not yielding
an issued patent. A court may also refuse to stop the third party from using the technology at issue in a proceeding on the
grounds that our owned or in-licensed patents do not cover such technology. Furthermore, because of the substantial amount
of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential
information or trade secrets could be compromised by disclosure during this type of litigation. Any of the foregoing could
allow such third parties to develop and commercialize competing technologies and products and have a material adverse
impact on our business, financial condition, results of operations, and prospects.

Interference or derivation proceedings provoked by third parties or brought by us or declared by the USPTO may be

necessary to determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome
could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our
business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms or at all, or if a
non-exclusive license is offered and our competitors gain access to the same technology. Our defense of litigation or
interference or derivation proceedings may fail and, even if successful, may result in substantial costs, and distract our
management and other employees. In addition, the uncertainties associated with litigation could have a material adverse
effect on our ability to raise the funds necessary to continue our clinical trials, continue our research programs, license
necessary technology from third parties, or enter into development partnerships that would help us bring our product
candidates to market.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation,

there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.
There could also be public announcements of the results of hearings, motions, or other interim proceedings or developments.
If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of
our common stock.

Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their
intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the
success of our business.

Our commercial success depends upon our ability and the ability of our collaborators to develop, manufacture, market

and sell our product candidates and use our proprietary technologies without infringing, misappropriating or otherwise
violating the intellectual property and proprietary rights of third parties. There is considerable patent and other intellectual
property litigation in the pharmaceutical and biotechnology industries. We may become party to, or threatened with,
adversarial proceedings or litigation regarding intellectual property rights with respect to our technology and product
candidates, including interference proceedings, post grant review, inter partes review, and derivation proceedings before the
USPTO and similar proceedings in foreign jurisdictions such as oppositions before the European Patent Office. Numerous
U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which
we are pursuing development candidates. As the biotechnology and pharmaceutical industries expand and more patents are
issued, the risk increases that our technologies or product candidates that we may identify may be subject to claims of
infringement of the patent rights of third parties.

69

The legal threshold for initiating litigation or contested proceedings is low, so that even lawsuits or proceedings with a
low probability of success might be initiated and require significant resources to defend. Litigation and contested proceedings
can also be expensive and time-consuming, and our adversaries in these proceedings may have the ability to dedicate
substantially greater resources to prosecuting these legal actions than we can. The risks of being involved in such litigation
and proceedings may increase if and as our product candidates near commercialization and as we gain the greater visibility
associated with being a public company. Third parties may assert infringement claims against us based on existing patents or
patents that may be granted in the future, regardless of merit. We may not be aware of all such intellectual property rights
potentially relating to our technology and product candidates and their uses, or we may incorrectly conclude that third party
intellectual property is invalid or that our activities and product candidates do not infringe such intellectual property. Thus,
we do not know with certainty that our technology and product candidates, or our development and commercialization
thereof, do not and will not infringe, misappropriate or otherwise violate any third party’s intellectual property.

Third parties may assert that we are employing their proprietary technology without authorization. There may be third-
party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment
related to the discovery, use or manufacture of the product candidates that we may identify or related to our technologies.
Because patent applications can take many years to issue, there may be currently pending patent applications which may later
result in issued patents that the product candidates that we may develop may be found to infringe. In addition, third parties
may obtain patents in the future and claim that use of our technologies infringes upon these patents. Moreover, as noted
above, there may be existing patents that we are not aware of or that we have incorrectly concluded are invalid or not
infringed by our activities. If any third-party patents were held by a court of competent jurisdiction to cover, for example, the
manufacturing process of the product candidates that we may develop, any molecules formed during the manufacturing
process or any final product itself, the holders of any such patents may be able to block our ability to commercialize such
product candidate unless we obtained a license under the applicable patents, or until such patents expire.

Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our
ability to further develop and commercialize the product candidates that we may identify. Defense of these claims, regardless
of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from
our business. In the event of a successful claim of infringement against us, we may have to pay substantial damages,
including treble damages and attorneys’ fees for willful infringement, pay royalties, redesign our infringing products, or
obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary
expenditure.

We may choose to take a license or, if we are found to infringe, misappropriate or otherwise violate a third party’s

intellectual property rights, we could also be required to obtain a license from such third party to continue developing,
manufacturing and marketing our technology and product candidates. However, we may not be able to obtain any required
license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive,
thereby giving our competitors and other third parties access to the same technologies licensed to us and could require us to
make substantial licensing and royalty payments. We could be forced, including by court order, to cease developing,
manufacturing and commercializing the infringing technology or product. In addition, we could be found liable for
significant monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a
patent or other intellectual property right and could be forced to indemnify our customers or collaborators. A finding of
infringement could prevent us from commercializing our product candidates or force us to cease some of our business
operations, which could materially harm our business. In addition, we may be forced to redesign our product candidates, seek
new regulatory approvals, and indemnify third parties pursuant to contractual agreements. Claims that we have
misappropriated the confidential information or trade secrets of third parties could have a similar material adverse effect on
our business, financial condition, results of operations, and prospects.

Intellectual property litigation or other legal proceedings relating to intellectual property could cause us to spend
substantial resources and distract our personnel from their normal responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us

to incur significant expenses and could distract our technical and management personnel from their normal responsibilities.
In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or
developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse
effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and
reduce the resources available for development activities or any future sales, marketing, or distribution activities. We may not
have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors
may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater

70

financial resources and may also have an advantage in such proceedings due to their more mature and developed intellectual
property portfolios. Uncertainties resulting from the initiation and continuation of intellectual property litigation or other
proceedings could compromise our ability to compete in the marketplace.

Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee
payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or
eliminated for noncompliance with these requirements.

Periodic maintenance, renewal and annuity fees and various other government fees on any issued patent and pending
patent application must be paid to the USPTO and foreign patent agencies in several stages or annually over the lifetime of
our owned and in-licensed patents and patent applications. The USPTO and various foreign governmental patent agencies
require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent
application process. In certain circumstances, we rely on our licensing partners to pay these fees to, or comply with the
procedural and documentary rules of, the relevant patent agency. With respect to our patents, we rely on an annuity service,
outside firms, and outside counsel to remind us of the due dates and to make payment after we instruct them to do so. While
an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable
rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application,
resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in
abandonment or lapse of a patent or patent application include failure to respond to official actions within prescribed time
limits, non-payment of fees and failure to properly legalize and submit formal documents. In such an event, potential
competitors might be able to enter the market with similar or identical products or technology. If we or our licensors fail to
maintain the patents and patent applications covering our product candidates, it would have a material adverse effect on our
business, financial condition, results of operations, and prospects.

If we fail to comply with our obligations in our intellectual property licenses and funding arrangements with third parties,
or otherwise experience disruptions to our business relationships with our licensors, we could lose intellectual property
rights that are important to our business.

We are party to license and funding agreements that impose, and we may enter into additional licensing and funding

arrangements with third parties that may impose, diligence, development, and commercialization timelines, milestone
payment, royalty, insurance and other obligations on us. Under our existing licensing and funding agreements, we are
obligated to pay royalties on net product sales of product candidates or related technologies to the extent they are covered by
the agreements. If we fail to comply with such obligations under current or future license and funding agreements, our
counterparties may have the right to terminate these agreements or require us to grant them certain rights. Such an occurrence
could materially adversely affect the value of any product candidate being developed under any such agreement. Termination
of these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate
new or reinstated agreements with less favorable terms, or cause us to lose our rights under these agreements, including our
rights to important intellectual property or technology, which would have a material adverse effect on our business, financial
condition, results of operations, and prospects.

Disputes may arise regarding intellectual property subject to a licensing agreement, including:

•

•

•

•

•

•

the scope of rights granted under the license agreement and other interpretation related issues;

the extent to which our technology and processes infringe on intellectual property of the licensor that is not
subject to the licensing agreement;

the sublicensing of patent and other rights under our collaborative development relationships;

our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

the inventorship and ownership of inventions and know-how resulting from the joint creation or use of
intellectual property by our licensors and us and our partners; and

the priority of invention of patented technology.

In addition, the agreements under which we currently license intellectual property or technology from third parties are

complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any
contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant
intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant
agreement, either of which could have a material adverse effect on our business, financial condition, results of operations,

71

and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain
our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and
commercialize the affected technology and product candidates, which could have a material adverse effect on our business,
financial conditions, results of operations, and prospects.

Our current or future licensors may have relied on third-party consultants or collaborators or on funds from third parties

such that our licensors are not the sole and exclusive owners of the patents and patent applications we in-license. If other
third parties have ownership rights to patents and/or patent applications we in-license, they may be able to license such
patents to our competitors, and our competitors could market competing products and technology. This could have a material
adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.

In spite of our best efforts, our licensors might conclude that we have materially breached our license agreements and

might therefore terminate the license agreements, thereby removing our ability to develop and commercialize product
candidates and technology covered by these license agreements. If these in-licenses are terminated, or if the underlying
intellectual property fails to provide the intended exclusivity, competitors would have the freedom to seek regulatory
approval of, and to market, products and technologies identical to ours. This could have a material adverse effect on our
competitive position, business, financial conditions, results of operations, and prospects.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.

We or our licensors may be subject to claims that former employees, collaborators or other third parties have an
interest in our owned or in-licensed patents, trade secrets, or other intellectual property as an inventor or co-inventor. For
example, we or our licensors may have inventorship disputes arise from conflicting obligations of employees, consultants or
others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other
claims challenging inventorship or our or our licensors’ ownership of our owned or in-licensed patents, trade secrets, or other
intellectual property. If we or our licensors fail in defending any such claims, in addition to paying monetary damages, we
may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property that is
important to our product candidates. Even if we are successful in defending against such claims, litigation could result in
substantial costs and be a distraction to management and other employees. Any of the foregoing could have a material
adverse effect on our business, financial condition, results of operations and prospects.

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

In addition to seeking patents for some of our technology and product candidates, we also rely on trade secrets and
confidentiality agreements to protect our unpatented know-how, technology, and other proprietary information, to maintain
our competitive position. We seek to protect our trade secrets and other proprietary technology, in part, by entering into non-
disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate
collaborators, outside scientific collaborators, CROs, contract manufacturers, consultants, advisors, and other third parties.
We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants. We
cannot guarantee that we have entered into such agreements with each party that may have or has had access to our trade
secrets or proprietary technology. Despite these efforts, any of these parties may breach the agreements and disclose our
proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches.
Detecting the disclosure or misappropriation of a trade secret and enforcing a claim that a party illegally disclosed or
misappropriated a trade secret is difficult, expensive, and time-consuming, and the outcome is unpredictable. In addition,
some courts inside and outside of the United States are less willing or unwilling to protect trade secrets. If any of our trade
secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right
to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any
of our trade secrets were to be disclosed to or independently developed by a competitor or other third party, our competitive
position would be materially and adversely harmed.

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

Our registered and unregistered trademarks or trade names may be challenged, infringed, circumvented, or declared

generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade
names, which we need to build name recognition among potential collaborators or customers in our markets of interest. At
times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity
and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims
brought by owners of other registered trade names or trademarks that incorporate variations of our unregistered trade names

72

or trademarks. Over the long term, if we are unable to successfully register our trade names and trademarks and establish
name recognition based on our trade names and trademarks, then we may not be able to compete effectively, and our business
may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trade names and trademarks may
be ineffective and could result in substantial costs and diversion of resources and could adversely impact our financial
condition or results of operations.

Intellectual property rights do not necessarily address all potential threats.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property

rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For
example:

•

•

•

•

•

•

•

•

•

•

•

•

we, or our license partners or current or future collaborators, might not have been the first to file patent
applications covering certain of our or their inventions;

others may independently develop similar or alternative technologies or duplicate any of our technologies
without infringing our owned or in-licensed intellectual property rights;

it is possible that our owned and in-licensed pending patent applications or those we may own or in-license in the
future will not lead to issued patents;

issued patents that we hold rights to may be held invalid or unenforceable, including as a result of legal
challenges by our competitors;

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

we cannot ensure that any of our pending patent applications, if issued, or those of our licensors, will include
claims having a scope sufficient to protect our product candidates;

we cannot ensure that any patents issued to us or our licensors will provide a basis for an exclusive market for
our commercially viable product candidates or will provide us with any competitive advantages;

we cannot ensure that our commercial activities or product candidates will not infringe upon the patents of
others;

we cannot ensure that we will be able to successfully commercialize our product candidates on a substantial
scale, if approved, before the relevant patents that we own, or license expire;

we may not develop additional proprietary technologies that are patentable;

the patents of others may harm our business; and

we may choose not to file a patent in order to maintain certain trade secrets or know-how, and a third party may
subsequently file a patent covering such intellectual property.

Should any of these events occur, they could have a material adverse effect on our business, financial condition, results

of operations, and prospects.

Risks related to our employees, managing our growth and our operations

Our future success depends on our ability to retain our key personnel and to attract, retain and motivate qualified
personnel.

We are highly dependent on the expertise of David L. Lucchino, our President and Chief Executive Officer, as well as
the other principal members of our management, scientific, and clinical teams. Although we have employment agreements,
offer letters or consulting agreements with our executive officers, these agreements do not prevent them from terminating
their services at any time.

If we lose one or more of our executive officers or key employees, our ability to implement our business strategy

successfully could be seriously harmed. Furthermore, replacing executive officers and key employees may be difficult and
may take an extended period because of the limited number of individuals in our industry with the breadth of skills and
experience required to develop, gain regulatory approval of and commercialize product candidates successfully. Competition

73

to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these additional key personnel
on acceptable terms given the competition among numerous biotechnology and pharmaceutical companies for similar
personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research
institutions.

In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating

our research and development and commercialization strategy. Our consultants and advisors may be engaged by other
companies or organizations and may have commitments that limit their availability. If we are unable to continue to attract and
retain highly qualified personnel, our ability to develop and commercialize our product candidates will be limited.

We expect to expand our development, regulatory, and sales and marketing capabilities, and as a result, we may encounter
difficulties in managing our growth, which could disrupt our operations.

Notwithstanding COVID-19, we have experienced and expect to continue to experience significant growth in the
number of our employees and the scope of our operations, particularly in the areas of clinical development, regulatory affairs,
quality and sales and marketing. To manage our anticipated future growth, we must continue to implement and improve our
managerial, operational and financial systems, expand our facilities or acquire new facilities, and continue to recruit and train
additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in
managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our
operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs
and may divert our management and business development resources. Any inability to manage growth could delay the
execution of our business plans or disrupt our operations.

We may engage in transactions that could disrupt our business, cause dilution to our shareholders or reduce our financial
resources.

In the future, we may enter into transactions to acquire or in-license rights to product candidates, products or
technologies, or to acquire other businesses. If we do identify suitable candidates, we may not be able to enter into such
transactions on favorable terms, or at all. Any such acquisitions or in-licenses may not strengthen our competitive position,
and these transactions may be viewed negatively by analysts, investors, customers, or other third parties with whom we have
relationships. We may decide to incur debt in connection with an acquisition, or in-license or issue our common stock or
other equity securities as consideration for the acquisition, which would reduce the percentage ownership of our existing
stockholders. We could incur losses resulting from undiscovered liabilities of the acquired business that are not covered by
the indemnification we may obtain from the sellers of the acquired business. In addition, we may not be able to successfully
integrate the acquired personnel, technologies, and operations into our existing business in an effective, timely, and
nondisruptive manner. Such transactions may also divert management attention from day-to-day responsibilities, increase our
expenses, and reduce our cash available for operations and other uses. We cannot predict the number, timing or size of future
acquisitions or in-licenses or the effect that any such transactions might have on our operating results.

Our business and operations would suffer in the event of security breaches or system failures.

The U.S. federal and various state and foreign governments have enacted or proposed requirements regarding the
collection, distribution, use, security and storage of personally identifiable information and other data relating to individuals.
In the ordinary course of our business, we and third parties with which we have relationships will continue to collect and
store sensitive data, including clinical trial data, proprietary business information, personal data and personally identifiable
information of our clinical trial subjects and employees, in data centers and on networks. The secure processing, maintenance
and transmission of this information is critical to our operations. Despite the implementation of security measures, our
computer systems, as well as those of our CROs and other contractors and consultants, are vulnerable to damage from
computer viruses, unauthorized access, malfeasance, natural and manmade disasters (including hurricanes), terrorism, war,
and telecommunication, electrical failures or other disruptions. Attacks upon information technology systems are increasing
in their frequency, levels of persistence, sophistication and intensity, and are being conducted by sophisticated and organized
groups and individuals with a wide range of motives and expertise. For instance, companies have experienced an increase in
phishing and social engineering attacks from third parties in connection with COVID-19 global pandemic. Furthermore,
because the techniques used to obtain unauthorized access to, or to sabotage, systems change frequently and often are not
recognized until launched against a target, we may be unable to anticipate these techniques or implement adequate
preventative measures. We may also experience security breaches that may remain undetected for an extended period. A
number of proposed and enacted federal, state and international laws and regulations obligate companies to notify individuals

74

of security breaches involving particular personally identifiable information, which could result from breaches experienced
by us or by third parties, including collaborators, vendors, contractors, or other organizations with which we have formed
strategic relationships. While we do not believe that we have experienced any such system failure, accident, or security
breach to date, if such an event were to occur and cause interruptions in our or their operations, it could result in delays
and/or material disruptions of our research and development programs. For example, the loss of preclinical or clinical trial
data from completed, ongoing, or planned trials could result in delays in our regulatory approval efforts and significantly
increase our costs to recover or reproduce the data. Likewise, we currently rely on third parties for the manufacture of our
product candidates and to conduct clinical trials, and similar events relating to their computer systems could also have a
material adverse effect on our business. Any such access, disclosure, notifications, follow-up actions related to such a
security breach or other loss of information could result in legal claims or proceedings, liability under data protection laws,
and significant costs, including regulatory penalties, fines, and legal expenses, and such an event could disrupt our
operations, cause us to incur remediation costs, damage our reputation, and cause a loss of confidence in us and our or such
third parties’ ability to conduct clinical trials, which could adversely affect our reputation and delay the clinical development
of our product candidates.

Risks related to our common stock

The market price of our common stock has been volatile and fluctuated and may in future fluctuate substantially, which
could result in substantial losses for our stockholders.

The market price of our common stock has been highly volatile and subject to wide fluctuations in response to various

factors, some of which are beyond our control. In addition to the factors discussed in this section titled “Risk factors” and
elsewhere in this Annual Report on Form 10-K, these factors include:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

any delay in the ultimate completion of our Phase 2a clinical trial, enrollment or ultimate completion of our
Phase 1b clinical studies in ARHL and severe SNHL, and other planned clinical trials of FX-322 for the
treatment of SNHL;

the results of the Phase 2a clinical trial, the Phase 1b clinical studies in ARHL and severe SNHL, or other
planned clinical trials of FX-322 for the treatment of SNHL or clinical trials of our competitors for the same or
similar indication. For example, the price of our common stock decreased significantly following the
announcement of our Phase 2a interim results, showing that four weekly injections in subjects with mild to
moderately severe SNHL did not demonstrate improvements in hearing measures versus placebo;

our ability to develop additional product candidates based on our PCA platform, including MS;

any delay in submitting a regulatory filing and any adverse development or perceived adverse development with
respect to the regulatory review of such filing;

failure to successfully develop and commercialize FX-322 for the treatment of SNHL or any future product
candidate;

inability to obtain additional funding;

regulatory or legal developments in the United States and other countries applicable to our PCA platform or any
product candidate:

adverse regulatory decisions;

changes in the structure of healthcare payment systems;

adverse developments concerning our CMOs or CROs;

inability to obtain adequate product supply for our other product candidates, or the inability to do so at acceptable
prices;

introduction of new products, services or technologies by our competitors;

our ability to effectively manage our growth;

failure to meet or exceed financial projections we provide to the public;

failure to meet or exceed the estimates and projections of the investment community;

75

•

•

•

•

•

•

•

•

•

changes in the market valuations of companies similar to us;

market conditions in the biotechnology and pharmaceutical sectors, and the issuance of new or changed securities
analysts’ reports or recommendations;

announcements of significant acquisitions, strategic collaborations, joint ventures or capital commitments by us
or our competitors;

the termination of a collaboration agreement, licensing agreement or other strategic arrangement, or the inability
to establish additional collaboration arrangements that we need on favorable terms, or at all;

significant lawsuits, including patent or shareholder litigation, and disputes or other developments relating to our
proprietary rights, including patents, litigation matters, and our ability to obtain patent protection for our product
candidates and PCA platform;

additions or departures of key scientific or management personnel;

sales of our common stock by us or our shareholders in the future;

trading volume of our common stock; and

general economic, industry and market conditions.

In addition, the trading prices for common stock of biopharmaceutical companies have been highly volatile as a result

of the COVID-19 pandemic. The ongoing COVID-19 pandemic continues to rapidly evolve. The extent to which the
outbreak may impact our business and clinical trials will depend on future developments, which are highly uncertain and
cannot be predicted with confidence.

Our directors, executive officers and shareholders affiliated with our directors and executive officers own a significant
percentage of our common stock and, if they choose to act together, will be able to exert significant influence over matters
subject to shareholder approval.

Our directors, executive officers, and shareholders affiliated with our directors and executive officers exert significant

influence on us. As of March 19, 2021, these holders beneficially own approximately 15.1% of the voting power of our
outstanding common stock. As a result, these holders, acting together, have significant influence over all matters that require
approval of our stockholders, including the election of directors, amendments of our organizational documents, or approval
of any merger, sale of assets, or other major corporate transactions. The interests of these holders may not always coincide
with our corporate interests or the interests of other shareholders, and they may act in a manner with which our shareholders
may not agree or that may not be in the best interests of our other shareholders.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital
appreciation, if any, will be the sole source of gain for our stockholders.

We have never declared or paid any cash dividends on our common stock. We currently anticipate that we will retain
future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any
cash dividends for the foreseeable future. As a result, capital appreciation, if any, of our common stock will be the sole source
of gain on an investment in our common stock for the foreseeable future.

We will incur increased costs as a result of operating as a public company, and our management will be required to devote
substantial time to new compliance initiatives and corporate governance practices.

As a public company, and particularly after we no longer qualify as an emerging growth company, we will incur
significant legal, accounting and other expenses that we did not incur previously. The Sarbanes-Oxley Act of 2002, or SOX,
the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of The Nasdaq Stock Market
LLC, and other applicable securities rules and regulations impose various requirements on U.S. reporting public companies,
including the establishment and maintenance of effective disclosure and financial controls and corporate governance
practices. Our management and other personnel will need to devote a substantial amount of time to these compliance
initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some
activities more time consuming and costly. For example, we expect that these rules and regulations may make it more
expensive for us to obtain director and officer liability insurance, which in turn could make it more difficult for us to attract
and retain qualified senior management personnel or members for our board of directors. In addition, these rules and

76

regulations are often subject to varying interpretations, and, as a result, their application in practice may evolve over time as
new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding
compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

Pursuant to Section 404 of SOX, or Section 404, as a public company, we will be required to furnish a report by our
senior management on our internal control over financial reporting, and our independent registered public accounting firm
will be required to provide an attestation report on our internal control over financial reporting. However, while we remain an
emerging growth company, we will not be required to provide the attestation report. To ensure compliance with Section 404,
we are engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and
challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants,
and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue
steps to improve control processes as appropriate, validate through testing that controls are functioning as documented, and
implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts,
there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal control over
financial reporting is effective as required by Section 404. If we identify one or more material weaknesses, it could result in
an adverse reaction on the price of our common stock in the market due to a loss of confidence in the reliability of our
financial statements. Furthermore, if we are unable to conclude that our internal control over financial reporting is effective,
our investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our
common stock could decline.

We are an “emerging growth company” and a “smaller reporting company” and the reduced disclosure requirements
applicable to emerging growth companies and smaller reporting companies may make our common stock less attractive to
investors.

We are an “emerging growth company,” as defined in the JOBS Act, and a “smaller reporting company” as defined

under the rules promulgated under the Securities Act. As an emerging growth company and a smaller reporting company we
may follow reduced disclosure requirements and do not have to make all the disclosures that public companies that are not
emerging growth companies or smaller reporting companies do. We will remain an emerging growth company until the
earlier of (a) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more; (b) the last
day of the fiscal year following the fifth anniversary of the date of the completion of our initial public offering; (c) the date on
which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (d) the date on which
we are deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission, or SEC, which
means the market value of our voting and non-voting common stock that is held by non-affiliates exceeds $700 million as of
the last business day of our second fiscal quarter. For so long as we remain an emerging growth company, we are permitted
and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are
not emerging growth companies. These exemptions include:

•

•

•

•

•

not being required to comply with the auditor attestation requirements of Section 404;

an exemption from compliance with the requirement of the Public Company Accounting Oversight Board
regarding the communication of critical audit matters in the auditor’s report on the financial statements;

progressively adding to the number of years of audited financial statements required to be included in our
periodic reports; and

exemptions from the requirements of holding a nonbinding advisory vote on executive compensation,
stockholder approval of any golden parachute payments not previously approved and having to disclose the ratio
of the compensation of our chief executive officer to the median compensation of our employees.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended
transition period for complying with new or revised accounting standards. This allows an emerging growth
company to delay the adoption of certain accounting standards until those standards would otherwise apply to
private companies. We have elected to use the extended transition period for complying with new or revised
accounting standards; and as a result of this election, our financial statements may not be comparable to
companies that comply with public company effective dates.

We are also a smaller reporting company, and we will remain a smaller reporting company until the fiscal year
following the determination that our voting and non-voting common stock held by non-affiliates is more than $250 million
measured on the last business day of our second fiscal quarter, or our annual revenues are more than $100 million during the
most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is more than $700

77

million measured on the last business day of our second fiscal quarter. Similar to emerging growth companies, smaller
reporting companies are able to provide simplified executive compensation disclosure, are exempt from the auditor
attestation requirements of Section 404, and have certain other reduced disclosure obligations, including, among other things,
being required to provide only two years of audited financial statements and not being required to provide selected financial
data, supplemental financial information or risk factors.

We may choose to take advantage of some, but not all, of the available exemptions for emerging growth companies and

smaller reporting companies. We cannot predict whether investors will find our common stock less attractive if we 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 shares price may be more volatile.

Provisions in our restated certificate of incorporation and our amended and restated bylaws or Delaware law may
discourage, delay or prevent a merger, acquisition or other change in control of our company that our shareholders may
consider favorable, including transactions in which our shareholders might otherwise receive a premium for their shares.

Our restated certificate of incorporation and our amended and restated bylaws include certain anti-takeover provisions,

including those establishing:

•

•

•

•

•

•

•

•

•

a classified board of directors with three-year staggered terms, which may delay the ability of stockholders to
change the membership of a majority of our board of directors;

no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect
director candidates;

the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the
board of directors or the resignation, death or removal of a director, which prevents shareholders from filling
vacancies on our board of directors;

the ability of our board of directors to authorize the issuance of shares of preferred stock and to determine the
terms of those shares, including preferences and voting rights, without stockholder approval, which could be used
to significantly dilute the ownership of a hostile acquirer;

the ability of our board of directors to alter our bylaws without obtaining stockholder approval;

the required approval of the holders of at least two-thirds of the shares entitled to vote at an election of directors
to adopt, amend or repeal our bylaws or repeal the provisions of our restated certificate of incorporation
regarding the election and removal of directors:

a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual
or special meeting of our stockholders;

the requirement that a special meeting of stockholders may be called only by the chairman of the board of
directors, the chief executive officer, the president, or the board of directors, which may delay the ability of our
stockholders to force consideration of a proposal or to take action, including the removal of directors: and

advance notice procedures that stockholders must comply with in order to nominate candidates to our board of
directors or to propose matters to be acted upon at a shareholders’ meeting, which may discourage or deter a
potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or
otherwise attempting to obtain control of us.

These provisions could also limit the price that investors might be willing to pay in the future for shares of our common
stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for
appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders
to replace or remove our current management by making it more difficult for stockholders to replace members of our board
of directors.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the General

Corporation Law of the State of Delaware, which prohibits a person who owns in excess of 15% of our outstanding voting
stock from merging or combining with us for a period of three years after the date of the transaction in which the person
acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed
manner.

78

Our restated certificate of incorporation and amended and restated bylaws designates specific courts as the exclusive
forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain
a favorable judicial forum for disputes with us.

Our restated certificate of incorporation specifies that, unless we consent in writing to the selection of an alternative

forum to the fullest extent permitted by law, the Court of Chancery of the State of Delaware will be the sole and exclusive
forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim for 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 arising pursuant to any provision of the General Corporation Law of the State of Delaware, our restated certificate of
incorporation, or our amended and restated bylaws, (4) any action to interpret, apply, enforce, or determine the validity of our
restated certificate of incorporation or our amended and restated bylaws, or (5) any action asserting a claim governed by the
internal affairs doctrine. Under our restated certificate of incorporation, this exclusive forum provision will not apply to
claims which are vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery of the State of
Delaware, or for which the Court of Chancery of the State of Delaware does not have subject matter jurisdiction. In addition,
our amended and restated bylaws specifies that unless we consent in writing to the selection of an alternative forum, the
federal district courts of the United States of America shall, to the fullest extent permitted by law, be the exclusive forum for
the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. These
exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for
disputes with us or our directors, officers, or other employees, which may discourage such lawsuits against us and our
directors, officers and other employees. For example, stockholders who do bring a claim in the Court of Chancery could face
additional litigation costs in pursuing any such claim, particularly if they do not reside in or near the State of Delaware. The
Court of Chancery may also reach different judgments or results than would other courts, including courts where a
stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or
results may be more favorable to us than to our stockholders. The enforceability of similar choice of forum provisions in
other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection
with any applicable action brought against us, a court could find the choice of forum provisions contained in our amended
and restated certificate of incorporation to be inapplicable or unenforceable in such action. If a court were to find the choice
of forum provisions contained in our amended and restated certificate of incorporation or amended and restated bylaws to be
inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other
jurisdictions, which could adversely affect our business, financial condition, or results of operations.

General Risk Factors

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights
to our technologies or product candidates.

Until such time, if ever, as we can generate substantial revenues, we may finance our cash needs through a combination
of equity offerings, debt financings, marketing and distribution arrangements and other collaborations, strategic alliances and
licensing arrangements or other sources. We do not currently have any committed external source of funds. In addition, we
may seek additional capital due to favorable market conditions or strategic considerations, even if we believe that we have
sufficient funds for our current or future operating plans.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, our existing

stockholders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other
preferences that adversely affect the rights of our common stockholders. In addition, debt financing and preferred equity
financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific
actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds
through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be
required to relinquish valuable rights to our technologies, intellectual property, future revenue streams or product candidates
or grant licenses on terms that may not be favorable to us. Furthermore, any capital raising efforts may divert our
management from their day-to-day activities, which may adversely affect our ability to advance research programs, product
development activities or product candidates. If we are unable to raise additional funds when needed, we may be required to
delay, limit, reduce or terminate product candidate development or future commercialization efforts.

Changes to patent laws in the United States and other jurisdictions could diminish the value of patents in general, thereby
impairing our ability to protect our products.

Changes in either the patent laws or interpretation of patent laws in the United States, including patent reform

legislation such as the Leahy-Smith America Invents Act, or the Leahy-Smith Act, could increase the uncertainties and costs

79

surrounding the prosecution of our owned and in-licensed patent applications and the maintenance, enforcement, or defense
of our owned and in-licensed issued patents. The Leahy-Smith Act includes a number of significant changes to United States
patent law. These changes include provisions that affect the way patent applications are prosecuted, redefine prior art,
provide more efficient and cost-effective avenues for competitors to challenge the validity of patents, and enable third-party
submission of prior art to the USPTO during patent prosecution, and additional procedures to attack the validity of a patent at
USPTO-administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings.
Assuming that other requirements for patentability are met, prior to March 2013, in the United States, the first to invent the
claimed invention was entitled to the patent, while outside the United States, the first to file a patent application was entitled
to the patent. After March 2013, under the Leahy-Smith Act, the United States transitioned to a first-to-file system in which,
assuming that the other statutory requirements for patentability are met, the first inventor to file a patent application will be
entitled to the patent on an invention regardless of whether a third party was the first to invent the claimed invention. As
such, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of
our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect
on our business, financial condition, results of operations, and prospects.

In addition, the patent positions of companies in the development and commercialization of biologics and

pharmaceuticals are particularly uncertain. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection
available in certain circumstances and weakened the rights of patent owners in certain situations. This combination of events
has created uncertainty with respect to the validity and enforceability of patents once obtained. Depending on future actions
by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in
unpredictable ways that could have a material adverse effect on our patent rights and our ability to protect, defend and
enforce our patent rights in the future.

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

Filing, prosecuting, and defending patents on product candidates in all countries throughout the world would be
prohibitively expensive. In addition, the laws of some foreign countries do not protect intellectual property rights to the same
extent as federal and state laws in the United States, and even where such protection is nominally available, judicial and
governmental enforcement of such intellectual property rights may be lacking. 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 products
made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in
jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise
infringing products to territories where we have patent protection or licenses, but enforcement is not as strong as that in the
United States. These products may compete with our products, and our patents or other intellectual property rights may not
be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in

foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the
enforcement of patents, trade secrets, and other intellectual property protection, particularly those relating to biotechnology
products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in
violation of our intellectual property and proprietary rights generally. In addition, certain jurisdictions do not protect, to the
same extent or at all, inventions that constitute new methods of treatment.

Proceedings to enforce our intellectual property and proprietary rights in foreign jurisdictions could result in substantial
costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated
or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third parties to assert
claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any,
may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property and proprietary rights
around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we
develop or license.

Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to

third parties. In addition, many countries limit the enforceability of patents against government agencies or government
contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of
such patent. If we or any of our licensors are forced to grant a license to third parties with respect to any patents relevant to
our business, our competitive position may be impaired, and our business, financial condition, results of operations, and
prospects may be adversely affected.

80

We may be subject to claims by third parties asserting that our employees, consultants or contractors have wrongfully
used or disclosed confidential information of third parties, or we have wrongfully used or disclosed alleged trade secrets of
their current or former employers, or claims asserting we have misappropriated their intellectual property, or claiming
ownership of what we regard as our own intellectual property.

Many of our employees, consultants and contractors were previously employed at universities or other pharmaceutical

or biotechnology companies, including our competitors or potential competitors. Although we try to ensure that our
employees, consultants, and contractors do not use the proprietary information or know-how of others in their work for us,
we may be subject to claims that these individuals or we have used or disclosed intellectual property, including trade secrets
or other proprietary information, of any such individual’s current or former employer. Litigation may be necessary to defend
against these claims.

In addition, while it is our policy to require our employees, consultants and contractors who may be involved in the

development of intellectual property to execute agreements assigning such intellectual property to us, we may be
unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our
own. Our intellectual property assignment agreements with them may not be self-executing or may be breached, and we may
be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of
what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial
conditions, results of operations, and prospects.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable
intellectual property rights or personnel, which could have a material adverse effect on our competitive business position and
prospects. Such intellectual property rights could be awarded to a third party, and we could be required to obtain a license
from such third party to commercialize our technology or products, which license may not be available on commercially
reasonable terms, or at all, or such license may be non-exclusive. Even if we are successful in prosecuting or defending
against such claims, litigation could result in substantial costs and be a distraction to our management and employees.

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against companies following a decline in the market

price of their securities. This risk is especially relevant for us because biotechnology and pharmaceutical companies have
experienced significant share price volatility in recent years. For example, the price of our common stock decreased
significantly following the announcement of our Phase 2a interim results, showing that four weekly injections in subjects
with mild to moderately severe SNHL did not demonstrate improvements in hearing measures versus placebo. As a result, we
may be more susceptible to these types of lawsuits and legal proceedings than other companies with more stable security
prices. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources,
which could harm our business.

If securities or industry analysts issue an adverse or misleading opinion regarding our common stock, our stock price and
trading volume could decline.

The trading market for our common stock is influenced by the research and reports that industry or securities analysts

publish about us or our business. If any of the analysts who cover us issue an adverse or misleading opinion regarding us, our
business model, our intellectual property or our stock performance, or if our clinical studies and operating results fail to meet
the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail
to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price
or trading volume to decline.

Sales of a substantial number of shares of our common stock, or the perception that substantial sales might occur, could
cause the price of our common stock to fall.

Sales of a substantial number of shares of our common stock, or the perception that these sales might occur, could
depress the market price of our common stock and could impair our ability to raise capital through the sale of additional
equity securities. The shares of common stock that were sold in the initial public offering of our common stock are freely
transferable without restrictions or further registration under the Securities Act of 1933, as amended, or the Securities Act,
except for any shares acquired by our affiliates, as defined in Rule 144 under the Securities Act. The remaining shares of our

Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described
below.

Overview

We are a clinical-stage biotechnology company focused on harnessing the body’s innate biology to repair or reverse
damage caused by a broad range of degenerative diseases and a global leader in the science and development of medicines
for inner-ear cellular regeneration and hearing restoration. Our initial focus is on advancing our lead product candidate, FX-
322, through clinical studies with the goal of developing and commercializing a medicine to help millions of patients with the
most common form of hearing loss and build upon the potential of regenerative therapeutics for hearing.

Our initial therapeutic focus is sensorineural hearing loss, or SNHL, which is the most prevalent type of hearing loss.

We are developing FX-322 to treat the underlying cause of SNHL, which is the loss of hair cells. FX-322 is designed to
regenerate hair cells through the activation of progenitor cells already present in the ear. In our Phase 1/2 clinical trial
evaluating FX-322 in 23 patients with stable SNHL, we observed a statistically significant and clinically meaningful
improvement in key measures of hearing loss, including word recognition, and clarity of sounds, and FX-322 was observed
to be well-tolerated. We commenced dosing of a Phase 2a clinical trial of FX-322 in patients with SNHL in October 2019. In
September 2020, we completed enrollment of 95 patients across 16 sites in the Phase 2a clinical trial. In March 2021, we
announced topline, day-90 interim data from the Phase 2a clinical trial. The results showed that four weekly injections in
subjects with mild to moderately severe SNHL did not demonstrate improvements in hearing measures versus placebo. While
WR scores increased across all groups, repeated weekly injections appeared to dampen the hearing benefit observed
compared to other single injection-studies. The interim results also showed an unexpected apparent level of hearing benefit in
the placebo group that did not occur in previous trials and exceeded well-established published standards. No treatment-
related serious adverse events were observed in the study. We plan to report an analysis of the end of Phase 2a data (210
days) late in the second quarter of 2021. We are also working to identify a product candidate for the treatment of multiple
sclerosis, or MS. This program focuses on activating oligodendroglial progenitor cells in the central nervous system to repair
the myelin sheath that protects axons and may have the potential to repair damage done by the disease. We established an
internal research program using PCA to drive remyelination as a potential therapy for MS and have identified compounds
that display promising preliminary preclinical results in an in vivo model of remyelination. Our research efforts are focused
on optimizing these compounds and identifying a lead therapeutic candidate to advance into clinical trials. We have obtained
worldwide licenses for intellectual property from Scripps and Cambridge Enterprise on approaches to promote remyelination
of nerve fibers and are engaged in sponsoring clinical research to validate this approach at Cambridge University.

In March 2021, we announced new data from a Phase 1b clinical trial of FX-322 designed to evaluate the impact of
injection conditions on tolerability. The data showed hearing improvement from a single injection of FX-322. In the multi-
center, randomized study, subjects with mild to severe SNHL (n=33) were injected in one ear with FX-322 with the untreated
ear as the control. Hearing function was tested over the course of 90 days following dosing. Thirty-two (n=32) subjects
completed the 90 day clinical assessment period and, at day 90 following dosing, thirty-four percent (34%) of these subjects
achieved a ten percent (10%) or greater absolute improvement in WR scores in the treated ear, which was clinically
meaningful and statistically significant compared to the untreated ear (p <0.05). This included a subset of subjects that more
than doubled their WR scores. The single dose had a favorable safety profile and was well tolerated.

We commenced a Phase 1b clinical trial of FX-322 for age-related hearing loss in October 2020. The clinical trial is a

double-blind, placebo-controlled, randomized multicenter safety study of up to 30 individuals aged 66-85 with mild to
moderately severe age-related hearing loss. The primary objectives of the Phase 1b study are to assess the local and systemic
safety of a single dose of FX-322 and evaluate hearing responses in an older adult cohort. Study participants will be
randomized 4:1 to receive either FX-322 or placebo in one ear. Validated measures of hearing including WR, words-in-noise,
or WIN, and pure tone audiometry will be used. Safety, otologic and audiologic assessments will be conducted at day 30 and
90 following administration of FX-322 or placebo. We expect to share results from this clinical trial in the second quarter of
2021.

We also commenced a Phase 1b clinical trial of FX-322 in patients aged 18-65 with severe SNHL in November

2020. Severe SNHL is defined as a pure tone average deficit between 71-90 dB. Many patients with this clinical

89

profile typically would be candidates for cochlear implants. This clinical trial has a similar design to the age-related Phase
1b clinical trial that completed enrollment in October 2020. We expect to share results for the age-related Phase 1b study
second quarter 2021 and SNHL Phase 1b study in the third quarter of 2021.

In October 2019, we completed the initial public offering of our common stock, or the IPO. In the IPO, we issued and

sold 6,325,000 shares of our common stock at a price to the public of $14.00 per share, inclusive of the underwriters’
exercise in part of their over-allotment option. We received approximately $79.7 million in net proceeds, after deducting
underwriting discounts and commissions and other offering expenses. In July 2019, we closed our Series C convertible
preferred stock financing in which we issued and sold 39,492,960 shares of our Series C convertible preferred stock for
aggregate gross proceeds of approximately $61.7 million. In July 2019, we also entered into a License and Collaboration
Agreement, or the Astellas Agreement, with Astellas Pharma Inc., or Astellas, pursuant to which Astellas paid us an upfront
payment of $80.0 million.

In July 2020, we completed a private placement of our common stock to new and existing investors, or the Private

Placement. In the Private Placement, we issued and sold 2,350,108 shares of our common stock at a purchase price of $18.00
per share. We received approximately $40.1 million in net proceeds, after deducting placement agent fees and other offering
expenses. In connection with the Private Placement, we entered into a Registration Rights Agreement, or the Registration
Rights Agreement, with the investors purchasing shares in the Private Placement. Pursuant to the Registration Rights
Agreement, we filed a registration statement with the Securities and Exchange Commission, or the SEC, which was declared
effective on September 3, 2020, registering the resale of the shares sold in the Private Placement.

Since our formation in 2014, we have devoted substantially all our resources to developing our PCA platform,

conducting research and development activities, including product candidate development, recruiting skilled personnel,
establishing our intellectual property portfolio, and providing general and administrative support for these operations. We
have financed our operations primarily through proceeds from the sale of convertible notes, convertible preferred stock, the
common stock and the Astellas Agreement.

Since our formation, we have incurred significant operating losses and have not generated any revenue from the sale of
products. Our ability to generate any product revenue or product revenue sufficient to achieve profitability will depend on the
successful development and eventual commercialization of one or more of our product candidates. Our net losses were
$26.5 million and $18.7 million for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020,
we had an accumulated deficit of $95.4 million.

We expect our operating expenses to increase substantially in connection with the expansion of our product
development programs and capabilities. In addition, we expect to continue to incur significant additional costs associated
with operating as a public company. We will not generate revenue from product sales unless and until we successfully
complete clinical development, obtain regulatory approval for, and successfully commercialize our product candidates, or
until our collaborators do so, which could result in milestone payments or royalties to us. If we obtain regulatory approval for
any of our product candidates, we expect to incur significant expenses related to developing our commercialization capability
to support product sales, marketing and distribution.

As a result of these anticipated expenditures, we will need additional financing to support our continuing operations.

Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our cash needs
through a combination of public or private equity or debt financings and other sources, which may include current and new
collaborations with third parties. Adequate additional financing may not be available to us on acceptable terms, or at all. Our
inability to raise capital as and when needed would have a negative impact on our financial condition and our ability to
pursue our business strategy. We cannot be sure that we will ever generate sufficient revenue to achieve profitability.

Because of the numerous risks and uncertainties associated with the development of therapeutics, we are unable to
predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if
we can generate revenue from product sales, we may not become profitable. If we fail to become profitable or are unable to
sustain profitability on a continuing basis, then we may be required to raise additional capital on terms that are unfavorable to
us or we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

COVID-19

Our offices are located in states that are currently operating under a phased re-opening plan in response to the

COVID-19 pandemic. As of the date of the filing of this Annual Report, the majority of our employees continue to work
from home, while nearly a quarter to one-third of our workforce, consisting of mainly laboratory personnel, have periodically

90

worked in rotating teams to ensure the continuation of essential experiments. Our Farmington, CT research site, co-located
with the University of Connecticut, has resumed activity at a fifty percent level after a period of paused activity due to state
lock down orders previously in effect. Thus, while we have resumed experiments at our Farmington site, we have
transitioned certain key experiments to our offices in Woburn, MA and third parties and contract research organizations have
been engaged to advance certain projects. We have also taken steps consistent with the FDA’s updated industry guidance for
conducting clinical trials. The COVID-19 pandemic, and actions taken to mitigate it, have had and are expected to continue
to have an adverse impact on the economies and financial markets of many countries, including the geographical area in
which we operates, which could adversely impact our ability to raise additional capital when needed or on acceptable terms,
if at all. In addition, COVID-19 may cause significant disruptions in our business or operations, as well as the business and
operations of our CMOs, CROs and other third parties with whom we conduct business. The COVID-19 pandemic may also
adversely impact our clinical trials, which could impede, delay, limit or prevent the clinical development of our product
candidates and ultimately lead to the delay or denial of regulatory approval of our product candidates, which would
materially adversely affect our business and operations, including our ability to generate revenue.

License and collaboration agreements

Astellas Pharma Inc.

In July 2019, we entered into the Astellas Agreement with Astellas, under which we granted Astellas an exclusive,

royalty-bearing, sub-licensable, nontransferable license to certain patent rights to research, develop, manufacture, have
manufactured, use, seek, and secure regulatory approval for, commercialize, offer for sale, sell, have sold and import, and
otherwise exploit licensed products containing both a GSK-3 inhibitor and an HDAC inhibitor, or the Astellas licensed
products, including our product candidate FX-322, outside of the United States. We and Astellas have agreed to jointly
develop the Astellas licensed products, including carrying out joint studies. Each party has agreed to use commercially
reasonable efforts to carry out development activities assigned to it under an agreed-upon development plan. Astellas has
agreed to use commercially reasonable efforts to obtain regulatory approval for at least one Astellas licensed product in
SNHL and in age-related hearing loss, in each case in one major Asian country and one major European country. We have
agreed to use commercially reasonable efforts to obtain regulatory approval for at least one Astellas licensed product in the
United States. Astellas has the sole right to commercialize the Astellas licensed products outside of the United States and we
have the sole right to commercialize the Astellas licensed products in the United States. Astellas has agreed to use
commercially reasonable efforts to commercialize Astellas licensed products in a major Asian country and a major European
country following receipt of regulatory approval in such countries.

As a consideration for the licensed rights under the Astellas Agreement, Astellas paid us an upfront payment of $80.0

million in July 2019 and has agreed to pay potential development milestones up to $230.0 million. Specifically, we would
receive development milestone payments of $65.0 million and $25.0 million upon the first dosing of a patient in Phase 2b
clinical trial for SNHL in Europe and Asia, respectively and $100.0 million and $40.0 million upon the first dosing of a
patient in a Phase 3 clinical for SNHL in Europe and Asia, respectively. If the Astellas Licensed Products are successfully
commercialized, we would be eligible for up to $315.0 million in potential commercial milestone payments and tiered
royalties at rates ranging from low to mid-teen percentages. The parties shall share equally, on a 50/50 basis, all out-of-
pocket costs and joint study costs for all the joint activities conducted pursuant to the development plans or the joint
manufacturing plan. Pursuant to our Exclusive Patent License Agreement, or the MIT License, with the Massachusetts
Institute of Technology, or MIT, we are required to pay MIT a royalty on sublicense revenues. A royalty of $16.0 million
related to the $80.0 million upfront payment received from Astellas was expensed in the quarter ended September 30, 2019
and paid in November 2019. The $80.0 million upfront payment received from Astellas in July 2019 has been recorded as
deferred revenue and is being recognized as revenue, using the input method, over the period in which we will be conducting
Phase 2a clinical trials for FX-322. As of December 31, 2020, we have recognized $65.9 million of the $80.0 million since
the agreement was executed in 2019.

Massachusetts Institute of Technology

In December 2016, we entered into the MIT License, with MIT under which we received an exclusive, worldwide,

royalty-bearing license to certain patent rights to develop, make, have made, use, sell, offer to sell, lease, and import
products, or the MIT licensed products, and to develop and perform processes, or the MIT licensed processes, which
incorporate the licensed technology for the treatment of disease, including but not limited to the prevention and remediation
of hearing loss. We are required to use diligent efforts to develop and commercialize the MIT licensed products or processes,
and to make such products or processes reasonably available to the public. We are also subject to certain development
obligations with regards to a first MIT licensed product. We have satisfied certain obligations related to preclinical studies
and the filing of an IND for a first MIT licensed product with our development activities related to FX-322. Our future
development obligations are: (i) to commence a Phase II clinical trial for such product within two years of the IND filing for
such product, (ii) to commence a Phase III clinical trial for such product within five years of the IND filing for such product,

91

(iii) to file a New Drug Application, or NDA, or equivalent with the FDA or comparable European regulatory agency for
such product within nine years of the IND filing for such product, and (iv) to make a first commercial sale of such product
within 11 years of the IND filing for such product. We also have certain development obligations with regards to a second
MIT licensed product.

Upon entering into the MIT License, we paid a $50 thousand license fee payment and issued shares of our common
stock equal to 5% of our then-outstanding capital stock to MIT. We are required to pay certain annual license maintenance
fees ranging from $30 thousand to $0.1 million per year prior to first commercial sale of a MIT licensed product and an
annual license maintenance fee of $0.2 million every year afterwards, which may be credited to running royalties during the
same calendar year, if any. We are also required to make potential milestone payments in an aggregate amount of up to
$2.9 million on each MIT licensed product or process. In addition, we agreed to pay a low single-digit royalty on the MIT
licensed products and processes and a low-twenties royalty on sub-license revenues. In the year ended December 31, 2019,
we paid MIT a $16.0 million royalty on the upfront license fee received from Astellas. See “Business—License and
collaboration agreements—Massachusetts Institute of Technology.”

Massachusetts Eye and Ear (Formerly Massachusetts Eye and Ear Infirmary)

In February 2019, we entered into an Non-Exclusive Patent License Agreement, or the MEE License, with the
Massachusetts Eye and Ear, or MEE, under which we received a non-exclusive, non-sub-licensable, worldwide, royalty-
bearing license to certain patent rights to develop, make, have made, use, sell, offer to sell, lease, and import products, and to
develop and perform processes that incorporate the licensed technology for the treatment or prevention of hearing loss, or the
MEE licensed products. We are obligated to use diligent efforts to develop and commercialize the MEE licensed products.
We are also subject to milestone timeline obligations to dose a first patient in a Phase II trial by December 31, 2020 and to
dose a first patient in a Phase III trial by December 31, 2024.

Upon entering into the MEE License, we made a $20 thousand license fee payment. We are obligated to pay certain

annual license maintenance fees between $5 thousand and $7.5 thousand per each MEE patent family case number included
in the licensed MEE patent rights prior to first commercial sale of an MEE licensed product. We are also obligated to pay a
minimum annual royalty payment of $15 thousand per each MEE patent family case number included in the licensed MEE
patent rights after first commercial sale of an MEE licensed product. We are also obligated to make milestone payments up to
$350 thousand on each product or process that incorporates the licensed patent rights. In addition, we have agreed to pay a
low single-digit royalty on products and processes that incorporate the licensed patent rights. See “Business—License and
collaboration agreements—Massachusetts Eye and Ear.”

The Scripps Research Institute (California Institute for Biomedical Research)

In September 2018, we entered into a license agreement, or the CALIBR License, with the California Institute for
Biomedical Research, or CALIBR, a division of Scripps, under which we received an exclusive, worldwide, royalty-bearing
license to certain patent rights to make, have made, use, sell, offer to sell, and import products, or the CALIBR licensed
products, which incorporate licensed technology for the treatment of MS. We have agreed to use commercially reasonable
efforts to develop, manufacture, and sell at least one CALIBR licensed product. We are also subject to certain milestone
timeline obligations, which may be extended in certain circumstances as described in the CALIBR License, to: (i) submit an
IND (or equivalent) for a CALIBR licensed product by the 30th month after the effective date of the CALIBR License,
(ii) initiate a Phase II clinical trial (or equivalent) for a CALIBR licensed product by the fourth anniversary of the effective
date of the CALIBR License, and (iii) initiate a Phase III clinical trial (or equivalent) for a CALIBR licensed product by the
sixth anniversary of the effective date of the CALIBR License.

Upon entering into the CALIBR License, we made a $1.0 million license fee payment, and are required to make
milestone payments in an aggregate amount of up to $26.0 million for each category of CALIBR licensed products. Category
1 is any CALIBR licensed products containing a compound that modulates any muscarinic receptor, and Category 2 is any
CALIBR licensed products not included in Category 1 that could differentiate oligodendrocyte precursor cells from in vitro
studies and/or are active in animal models relevant to MS. We are also required to pay a mid-single-digit royalty on CALIBR
licensed products and a royalty on sub-license revenues ranging from a low-teen percentage to 50%. See “Business—License
and collaboration agreements—The Scripps Research Institute (California Institute for Biomedical Research).”

92

The Scripps Research Institute

In September 2018, we entered into a Research Funding and Option Agreement, or the Scripps option agreement, with

Scripps, under which we were granted an exclusive option to acquire an exclusive, sublicensable, worldwide license under
certain intellectual property related to the treatment of MS. As consideration for the Scripps option agreement, we are
required to make funding payments totaling $0.7 million to Scripps to support its research activities. Scripps has agreed to
use reasonable efforts to perform the research program pursuant to the Scripps option agreement.

The Scripps option agreement had a one-year term and was renewed for a second year by mutual written agreement.

We have the right to terminate by giving 90 days’ advance notice. Scripps has the right to terminate in the event of
nonpayment by us that remains uncured for 10 days. Each party has the right to terminate in the event of the other party’s
material breach that remains uncured for 60 days or if the other party becomes bankrupt. See “Business—License and
collaboration agreements—The Scripps Research Institute (California Institute for Biomedical Research).”

In September 2020, we extended the term of the option agreement through the end of December 2021. As
consideration for this extension, we are required to make additional funding payments of $0.6 million to Scripps through
December 2021.

We have the right to terminate by giving 90 days’ advance notice. Scripps has the right to terminate in the event of
nonpayment by us that remains uncured for 10 days. Each party has the right to terminate in the event of the other party’s
material breach that remains uncured for 60 days or if the other party becomes bankrupt.

Cambridge Enterprise Limited

In December 2019, we entered into an Exclusive Patent License Agreement, or the Cambridge License, with

Cambridge, under which we received an exclusive, worldwide, royalty-bearing license to certain patent rights to make, have
made, use, sell, offer to sell, and import products, or the Cambridge licensed products, which incorporate licensed technology
for the treatment of demyelinating diseases. We also have the right to grant sublicenses under the Cambridge License.
Cambridge reserves the right to use for itself (as well as the investors and the funder) and the right to grant nonexclusive
licenses to other academic institutions for any academic publication, research and teaching and clinical patient care.

We have agreed to use diligent and good faith efforts to develop and commercially exploit at least one Cambridge
licensed product. Upon entering into the Cambridge License, we made a $50 thousand license fee payment. We are obligated
to pay an annual license fee of $50 thousand. We are also obligated to make milestone payments up to $10.5 million on each
Cambridge licensed product. In addition, we have agreed to pay a low single-digit royalty on products that incorporate the
licensed patent rights, subject to offset in certain circumstances.

The Cambridge License continues in effect on a country-by-country basis until the expiration or revocation, without

right of further appeal, of all licensed issued patents and filed patent applications, unless terminated earlier. We have the right
to terminate for any reason upon 90 days’ prior written notice. Each party has the right to terminate immediately if the other
party ceases to carry on its business. Either party may also terminate the Cambridge License for material breach if such
breach remains uncured for 30 days. Cambridge may also terminate the Cambridge License if we fail to diligently develop
and commercially exploit at least one Cambridge licensed product or we or our affiliates or sub-licensees commence any
action against Cambridge to declare or render any claim of the licensed patent rights invalid, unpatentable, unenforceable, or
not infringed.

Components of our results of operations

Revenue

To date, we have not generated any revenue from product sales and do not expect to generate any revenue from product

sales in the foreseeable future. In July 2019, we entered into the Astellas Agreement and received an upfront license fee
payment of $80.0 million. In accordance with ASC 606, Revenue Recognition, we are recognizing the $80.0 million as
revenue over the period that research and development services and the Phase 2a clinical study for FX-322 are being
provided using the input method. For the purpose of revenue recognition, this is the period from execution of the Astellas
Agreement to, based on management’s best estimate, the completion date of the Phase 2a clinical study. In the year ended
December 31, 2020, we recognized $37.0 million of the $80.0 million upfront fee as revenue. In the year ended December
31, 2019, we recognized $28.9 million of the upfront fee as revenue. The 2019 amount reflects revenue of $16.0 million
equal to the royalty expense under the MIT License as well as $12.9 million from applying the input method to the remaining
$64.0 million of the upfront payment.

Royalty

We are required to pay royalties under the MIT License on the receipt of fees for the sublicense of the MIT intellectual

property. We expensed the $16.0 million royalty due MIT on the $80.0 million license fee pursuant to the Astellas
Agreement in the third quarter of 2019. There were no royalties paid in the year ended December 31, 2020.

Research and development expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our

discovery efforts and for the development of our product candidate, FX-322. These include the following:

•

•

•

•

•

•

•

salaries, benefits and other related costs, including stock-based compensation expense, for personnel engaged in
research and development functions;

expenses incurred under agreements with third parties, including contract research organizations, or CROs, and
other third parties that conduct preclinical research and development activities and clinical trials on our behalf;

costs to manufacture our clinical trial material for use in our preclinical studies and clinical trials;

costs of outside consultants, including their fees and related travel expenses;

costs of laboratory supplies and acquiring, developing and manufacturing preclinical study and clinical trial
materials;

option and license payments made to third parties, including MIT, Scripps, MEE and Cambridge, for intellectual
property used in research and development activities; and

facility-related expenses, which include direct depreciation costs and expenses for rent and maintenance of
facilities and other operating costs if specifically, identifiable to research activities.

We expense research and development costs as incurred.

We track external research and development costs, including the cost of services, outsourced research and

development, clinical trials, contract manufacturing, laboratory equipment and maintenance, and certain other development
costs, by product candidate when the costs are specifically identifiable to a product candidate. Internal and external costs
associated with infrastructure resources, other research and development costs, facility-related costs, and depreciation and
amortization that are not identifiable to a specific product candidate are included in the platform development, early-stage
research, and unallocated expenses category in the table below.

We expect that our research and development expenses will continue to increase substantially for the foreseeable future

as we complete our Phase 2a clinical trial and additional clinical trials for FX-322 and continue to discover and develop
additional product candidates. Product candidates in later stages of clinical development generally have higher development
costs than those in earlier stages of clinical development, primarily due to increased scale, duration and the higher costs
associated with later stage clinical trials.

We cannot determine with certainty the duration and costs of future clinical trials of FX-322 or any other product
candidate we may develop or if, when, or to what extent we will generate revenue from the commercialization and sale of any
product candidate for which we obtain marketing approval. The duration, costs, and timing of clinical trials and development
of FX-322 and any other product candidate we may develop will depend on a variety of factors, including:

•

•

•

•

•

•

•

•

the scope, rate of progress, expense and results of clinical trials of FX-322, as well as of any future clinical trials
of other product candidates and other research and development activities that we may conduct;

the actual probability of success for our product candidates, including their safety and efficacy, early clinical
data, competition, manufacturing capability, and commercial viability;

significant and changing government regulation and regulatory guidance;

the timing and receipt of any marketing approvals;

the progress of the development efforts of parties with whom we may enter into collaboration agreements;

our ability to secure manufacturing supply through relationships with third parties;

the commercialization of our product candidates, if and when approved; and

the expense of filing, prosecuting, defending and enforcing any patent claims and other intellectual property
rights.

A change in the outcome of any of these variables with respect to the development of a product candidate could mean a

significant change in the costs and timing associated with the development of that product candidate.

General and administrative expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based

compensation, for personnel in our executive, finance, business development, and administrative functions. General and
administrative expenses also include legal fees relating to intellectual property and corporate matters; professional fees for
accounting, auditing, tax and consulting services; insurance costs; travel expenses; and facility-related expenses, which

95

include direct depreciation costs and expenses for rent and maintenance of facilities, and other operating costs that are not
specifically attributable to research and development activities.

We expect that our general and administrative expenses will increase in the future as we increase our personnel
headcount to support our continued research activities and development of product candidates. In addition, due to our IPO in
October 2019, we expect to incur increased expenses associated with being a public company, including costs of accounting,
audit, legal, regulatory, and tax-related services associated with maintaining compliance with the requirements of The Nasdaq
Stock Market LLC and the SEC; director and officer insurance costs; and investor and public relations costs.

Interest income

Interest income consists of interest earned on cash equivalents and short-term investments.

Realized gain on investments

Realized gain on investments represents the gain realized on our marketable securities in the years ended December 31,

2020 and 2019.

Foreign exchange (loss) gain

Foreign exchange (loss) gain represents the gain or loss recorded as a result of remeasuring the financial statements of

our foreign subsidiaries.

Income taxes

Since our inception in 2014, we have generated cumulative federal and state net operating loss and research and

development credit carryforwards for which we have not recorded any net tax benefit due to uncertainty around utilizing
these tax attributes within the respective carryforward periods.

As of December 31, 2020, we had federal net operating loss carryforwards of approximately $67,868 and

Massachusetts state operating loss carryforwards of approximately $43,386 which may be available to offset future taxable
income. The U.S. federal net operating loss carryforwards include $22,400 available to reduce future taxable income through
2037 and approximately $45,469 which do not expire and are available to reduce future taxable income indefinitely. The state
net operating loss carryforwards are available to offset future taxable income through 2040. As of December 31, 2020, we
also had federal and Massachusetts research and development tax credit carryforwards of $3,014 and $1,211, respectively,
which are available to offset federal and state tax liabilities through 2040 and 2035, respectively. Realization of future tax
benefits is dependent on many factors, including our ability to generate taxable income within the net operating loss
carryforward period. Net operating loss and tax credit carryforwards may become subject to an annual limitation in the event
of certain cumulative changes in the ownership interest of significant shareholders over a three-year period in excess of 50%,
as provided under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, respectively, as well as similar
state provisions. These ownership changes may limit the number of carryforwards that can be utilized annually to offset
future taxable income. In general, an ownership change, as defined by Section 382, results from transactions increasing the
ownership of certain shareholders or public groups in the stock of a corporation by more than 50% over a three-year period.
We have completed several financings and have conducted a study to assess whether a change of control has occurred or
whether there have been multiple changes of control since inception and have determined that an ownership change did occur
in March 2017. Accordingly, utilization of $12,400 of the U.S. net operating loss carryforwards which were incurred prior to
March 2017 (pre-ownership change) is limited under Section 382. After the Section 382 limitations, we may utilize
approximately $10,800 of our pre-ownership change net operating loss carryforwards based upon an annual usage of
approximately $1,600 for each of the next five years after the ownership change and approximately $180 for each of the 15
years thereafter. The remaining pre-ownership change net operating losses of approximately $1,600 were written off due to
expiration under limitation. The limitation has been determined by first multiplying the value of our stock at the time of the
ownership change by the applicable long-term tax-exempt rate. These carryforwards may be subject to further annual
limitations under Section 382 in the event of future changes in ownership. Additionally, we have determined an ownership
changed occurred in October of 2019 as a result of the IPO. Accordingly, utilization of approximately $46,123 of the U.S.
net operating loss carryforwards incurred prior to October 2019 is also limited under Section 382. We have determined we
will be able to utilize the entire $46,123 of our pre-ownership change net operating loss carryforwards based upon the
limitations calculated from the October 2019 ownership change. These carryforwards may be subject to further annual
limitations under Section 382 in the event of future changes in ownership.

Revenue

Revenue was $37.0 million for the year ended December 31, 2020 compared to $28.9 million for the year ended

December 31, 2019. In July 2019, we entered into the Astellas Agreement and received an upfront license fee payment of
$80.0 million. In accordance with ASC 606, we are recognizing the $80.0 million as revenue over the period that research
and development services and the Phase 2a clinical study for FX-322 are being provided using the input method. In the year
ended December 31, 2020, we recognized revenue of $37.0 million applying the input method to the upfront payment. In the
year ended December 31, 2019 we recognized revenue of $28.9 million applying the input method to the upfront payment.
We expect to recognize the remaining revenue under the Astellas Agreement in 2021.

Royalty Expense

We are required to pay royalties under the MIT License on the receipt of fees for the sublicense of the MIT
intellectual property. In the year ended December 31, 2019, we expensed the $16.0 million royalty due MIT on the $80.0
million upfront fee received from Astellas. No royalties were due in the year ended December 31, 2020.

Research and development expenses for the year ended December 31, 2020 were $37.4 million, compared to $18.8

million for the year ended December 31, 2019. The increase of $18.6 million was primarily due to an increase of $13.5
million in platform development, early-stage research and unallocated expenses and an increase of $5.1 million in FX-322
external research and development costs.

The $9.4 million of FX-322 external development costs incurred for the year ended December 31, 2020 consisted

primarily of $8.9 million of clinical and development costs associated with the Phase 2a and other related clinical trials of
FX-322, including $2.2 million related to drug manufacturing and development, and $0.4 million of third party consulting
costs. The $4.3 million of FX-322 external development costs incurred for the year ended December 31, 2019 consisted
primarily of $2.1 million of clinical development costs including manufacturing costs for FX-322 to be used in clinical trials,
$0.7 million of outside consulting costs, $1.1 million in clinical trial costs and $0.3 million in milestone payments under the
MIT License.

The $28.0 million of platform development, early-stage research and unallocated expenses incurred for the year ended

December 31, 2020 consisted primarily of $17.1 million of employee-related costs, including $4.0 million of stock
compensation expense, $6.7 million of outsourced research and development expense, and $1.7 million of other research and
development costs. This increase of $13.5 million from the year ended December 31, 2019 is primarily attributable to an
increase of $8.9 million in employee-related expenses associated with increased headcount to support pre-clinical and clinical
development of FX-322 and research on our PCA platform developments and a $1.7 million increase in other research and
development expenses, primarily related to consulting on programs excluding FX-322.

General and administrative expenses

General and administrative expenses were $27.1 million for the year ended December 31, 2020, compared to $14.8

million for the year ended December 31, 2019. General and administrative expenses increased $12.3 million due to an
increase of $8.0 million in employee-related costs, including $4.1 million in stock compensation expense, as we increase our
general and administrative headcount to manage our growth and the impact of being a public company, and increases of $2.3
million and $1.4 million in directors and officers insurance and public relations expense, respectively.

98

Interest income

Interest income was $1.0 million for the year ended December 31, 2020 compared to $1.8 million for the year ended

December 31, 2019, due to a decrease in interest rates in the current year.

Realized gain on investments

Realized gain on investments was $84 thousand for the year ended December 31, 2020 compared to $138 thousand for

the year ended December 31, 2019 due to a decrease in interest rates in the current year.

Foreign exchange (loss) gain

Foreign exchange loss was $4 thousand for the year ended December 31, 2020 compared to a gain of $7 thousand for

the year ended December 31, 2019. The decrease of $11 thousand was due to differences in foreign exchange remeasurement
of the financial statements of our foreign subsidiaries.

Liquidity and capital resources

Since our inception, we have incurred significant operating losses. We expect to continue to incur significant expenses

and operating losses for the foreseeable future as we advance the preclinical and clinical development of our product
candidates. We expect that our research and development and general and administrative costs will continue to increase,
including in connection with conducting preclinical studies and clinical trials for our product candidates, contracting with
contract manufacturing organizations, or CMOs, to support preclinical studies and clinical trials, expanding our intellectual
property portfolio, and providing general and administrative support for our operations particularly as we continue to operate
as a public company. As a result, we will need additional capital to fund our operations, which we may obtain from additional
equity or debt financings, collaborations, licensing arrangements or other sources.

We do not currently have any approved products and have never generated any revenue from product sales. We have
financed our operations primarily through proceeds from the sale of our convertible notes, convertible preferred stock, our
IPO, our Private Placement, the upfront payment under the Astellas Agreement, and a Term Loan. To date, we have raised
approximately $376.9 million through a combination of convertible notes, convertible preferred stock, the upfront payment
under the Astellas Agreement, grants, the IPO, our Private Placement, option exercises and Term Loan. Our cash, cash
equivalents and short-term investments totaled $220.3 million as of December 31, 2020. As of December 31, 2020, we had
$15.0 million of debt related to the Term Loan.

Net cash used by operating activities for the year ended December 31, 2020 was $45.2 million, consisting of a net loss

of $26.5 million as we incurred expenses associated with our FX-322 program, platform development and early-stage
research, and general and administrative expenses. In addition, we had non-cash charges of $11.6 million for depreciation,
stock-based compensation expense, and non-cash lease expense. Net cash used in operating activities was also impacted by a
net $30.2 million decrease in operating assets and liabilities, including a decrease of $37.0 million in deferred revenues from
the upfront payment under the Astellas Agreement, and increases in accounts payable, accrued expenses and prepaid expense
and other current assets of $4.3 million, $3.1 million, and $0.6 million, respectively.

Investing activities

Net cash provided by investing activities for the year ended December 31, 2020 was $10.4 million, which was
attributable to $43.4 million of redemptions of available for sale securities, partially offset by $26.3 million of available for
sale securities and $6.7 million of purchases of property and equipment, $2.6 million of which is related to the buildout of the
Company’s new Lexington office.

Financing activities

Net cash provided by financing activities for the year ended December 31, 2020 was $56.7 million, primarily

attributable to $40.1 million in net proceeds from the July 2020 Private Placement, $15.0 million in proceeds from the Term
Loan, and $1.5 million in proceeds from the exercise of stock options.

Cash flows for the year ended December 31, 2019

Operating activities

Net cash provided by operating activities for the year ended December 31, 2019 was $34.2 million, primarily

consisting of a net loss of $18.7 million as we incurred expenses associated with our FX-322 program, platform development
and early-stage research, and general and administrative expenses. In addition, we had non-cash charges of $4.3 million
primarily for depreciation, stock-based compensation expense and deferred lease incentives. Net cash used in operating
activities was also impacted by a net $48.7 million change in operating assets and liabilities, including an increase of
$51.1 million in deferred revenues from the upfront payment under the Astellas Agreement and a $1.5 million increase
accrued expenses, which were partially offset by an increase of $3.3 million in prepaid expenses and other current assets and
a $.6 million decrease in accounts payable.

Investing activities

Net cash used in investing activities for the year ended December 31, 2019 was $18.3 million, which was attributable

to $1.1 million of purchases of property and equipment and $17.2 million of net purchases of marketable securities.

Financing activities

Net cash provided by financing activities for the year ended December 31, 2019 was $142.0 million, consisting of

proceeds from our IPO of $79.7 million, the issuance of our Series C convertible preferred stock of $61.7 million, the
issuance of additional shares of our Series B convertible preferred stock of $0.3 million, and $0.3 million of proceeds from
the exercise of stock options.

Funding requirements

Our operating expenses increased substantially in the years ended December 31, 2020 and 2019 and are expected to

increase substantially in the future in connection with our ongoing activities, particularly as we advance FX-322 through
clinical trials and as we research and develop additional product candidates including preclinical activities, studies for INDs,
and initiation of human clinical trials. In addition, we expect to incur additional general and administrative costs to build the
infrastructure necessary to manage the growth of our research and development efforts and the increased costs associated
with operating as a public company.

Specifically, our costs and expenses will increase as we:

•

•

•

•

•

•

advance the clinical development of FX-322;

pursue the preclinical and clinical development of other product candidates using our PCA platform, including
our program for the treatment of MS;

in-license or acquire the rights to other products, product candidates or technologies;

maintain, expand, and protect our intellectual property portfolio;

hire additional personnel in research, manufacturing, and regulatory and clinical development, as well as
management personnel; and

expand our operational, financial, investor relations, and management systems and increase personnel, including
personnel to support our operations as a public company.

100

We believe that our existing cash, cash equivalents, and short-term investments, will enable us to fund our operating
expenses and capital expenditure requirements into 2023. We have based this estimate on assumptions that may prove to be
incorrect, and we could utilize our available capital resources sooner than we expect.

Because of the numerous risks and uncertainties associated with the research, development, and commercialization of

therapeutics, it is difficult to estimate with certainty the amount of our working capital requirements. Our future funding
requirements will depend on many factors, including:

•

•

•

•

•

•

•

•

•

•

the progress, costs, and results of our clinical development and clinical trials for FX-322;

the progress, costs, and results of our additional research and preclinical development programs, including our
program for the treatment of MS;

the outcome, timing and cost of meeting regulatory requirements established by the FDA and comparable foreign
regulatory authorities, if applicable, for our product candidates;

the costs and timing of internal process development, manufacturing activities, and clinical trial management
associated with FX-322 and other product candidates we advance through preclinical and clinical development;

our ability to establish and maintain strategic collaborations, licensing or other agreements and the financial
terms of such agreements;

the scope, progress, results, and costs of any product candidates that we may derive from our PCA platform or
any other product candidates we may develop alone or with collaborators;

the extent to which we in-license or acquire rights to other products, product candidates, or technologies;

additions or departures of key scientific or management personnel;

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

the costs and timing of future commercialization activities, including product manufacturing, marketing, sales,
and distribution for any product candidates for which we or our collaborators obtain marketing approval.

Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our cash needs

through a combination of public or private equity or debt financings and other sources, which may include current and new
collaborations with third parties. To the extent that we raise additional capital through the sale of equity or convertible debt
securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other
preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if
available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as
incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through other
sources, such as collaboration agreements, strategic alliances, licensing arrangements or marketing and distribution
arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, product development,
and research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to
raise additional funds when needed, we may be required to delay, limit, reduce, or terminate our product development or
future commercialization efforts or grant rights to develop and market products or product candidates that we would
otherwise prefer to develop and market ourselves.

on these lease agreements).

101

We have not included future milestone payments under our collaboration and license agreements in the table above
since the payment obligations under these agreements are contingent upon future events, such as the achievement of specified
product development milestones or generating product sales, and we are unable to estimate the timing or likelihood of
achieving these milestones or generating future product sales. We are also required to spend certain minimum amounts on
research and development of licensed products or processes under the MIT License, and may have certain funding
obligations under the Scripps option agreement, which are not included in the table above. See “—License and collaboration
agreements” for more information regarding our payment obligations under these agreements.

We also enter into contracts in the normal course of business with CROs, CMOs, universities, and other third parties

for preclinical research studies, clinical trials and testing and manufacturing services. These contracts generally do not
contain minimum purchase commitments and are cancelable by us upon prior written notice although, purchase orders for
clinical materials are generally non-cancelable. Payments due upon cancellation consist only of payments for services
provided or expenses incurred, including noncancelable obligations of our service providers, up to the date of cancellation or
upon completion of a manufacturing run. These payments are not included in the table above as the amount and timing of
such payments are not known or are not material.

Critical accounting policies and use of estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our audited
consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in
the United States. The preparation of our consolidated financial statements and related disclosures requires us to make
estimates and assumptions that affect the reported amounts of assets and liabilities, revenue, costs and expenses, and the
disclosure of contingent assets and liabilities in our consolidated financial statements. We base our estimates on historical
experience, known trends and events, and various other factors that we believe are reasonable under the circumstances, the
results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily
apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ
from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our consolidated financial
statements included elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies are
those most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Revenue recognition

We account for contracts with customers in accordance with Accounting Standards Codification (“ASC”), Topic 606,

Revenue from Contracts with Customers (“ASC 606”), including all amendments thereto. This standard applies to all
contracts with customers, except for contracts that are within the scope of other standards, such as collaborative arrangements
and leases. Our disclosure in the accompanying consolidated financial statements reflects the Company’s accounting policies
in compliance with this standard.

Under ASC 606, an entity recognizes revenue when or as its customer obtains control of promised goods or services, in

an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To
recognize revenue for arrangements that an entity determines are within the scope of ASC 606, the entity performs the
following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract;
(iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the
performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies its performance
obligations. We only apply the five-step model to contracts when it is probable that the entity will collect substantially all of
the consideration to which it will be entitled in exchange for the goods or services it transfers to the customer. Once a
contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and
identifies as a performance obligation each promise to transfer to the customer either (a) a good or service (or bundle of
goods and services) that is distinct, or (b) a series of distinct goods and services that are substantially the same and have been
the same pattern of transfer to the customer.

We assess whether each promised good or service is distinct for the purpose of identifying the performance obligations

in the contract. This assessment involves subjective determinations and requires management to make judgments about the
individual promised goods or services and whether such are separable from the other aspects of the contractual relationship.
Promised goods and services are considered distinct provided that: (i) the customer can benefit from the good or service
either on its own or together with other resources that are readily available to the customer (that is, the good or service is
capable of being distinct) and (ii) the entity’s promise to transfer the good or service to the customer is separately identifiable
from other promises in the contract (that is, the promise to transfer the good or service is distinct within the context of the
contract). In assessing whether a promised good or service is distinct, we consider factors such as the research, manufacturing
and commercialization capabilities of the collaboration partner (the “customer” in this type of arrangement) and the

102

availability of the associated expertise in the general marketplace. We also consider the intended benefit of the contract in
assessing whether a promised good or service is separately identifiable from other promises in the contract. If a promised
good or service is not distinct, an entity is required to combine that good or service with other promised goods or services
until it identifies a bundle of goods or services that is distinct. For each arrangement that results in revenues, we identify all
performance obligations, which may include, for example, a license to IP and know-how, research and development
activities, and/or manufacturing services.

In addition to any upfront payment, if the consideration promised in a contract includes a variable amount, we estimate

the amount of consideration to which it will be entitled in exchange for transferring the promised goods or services to a
customer. We determine the amount of variable consideration by using the expected value method or the most likely amount
method. We include the estimated variable consideration in the transaction price to the extent it is probable that a significant
reversal of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, we re-evaluate the
estimated variable consideration included in the transaction price and any related constraint, and if necessary, adjusts its
estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis in the period of
adjustment.

If an arrangement includes development and regulatory milestone payments, we evaluate whether the milestones are
considered probable of being reached and estimates the amount to be included in the transaction price using the most likely
amount method. There is considerable judgment involved in determining whether it is probable that a significant revenue
reversal would not occur. If it is probable that a significant revenue reversal will not occur, the associated milestone value is
included in the transaction price. Milestone payments that are not within our control or of the licensee such as regulatory
approvals, are generally not considered probable of being achieved until those approvals are received. At the end of each
subsequent reporting period, we re-evaluate the probability of achievement of all milestones subject to constraint and, if
necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up
basis, which would affect revenues and earnings in the period of adjustment.

For contracts that include sales-based royalties (including milestone payments based on the level of sales) promised in
the exchange for licenses of intellectual property, and the license is deemed to be the predominant item to which the royalties
relate, we recognize royalty revenue and sales-based milestone payments at the later of (i) when the related sales occur, or
(ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied. In determining
the transaction price, we adjust the promised amount of consideration for the effects of the time value of money if the timing
of payments provides the Company or the Company’s customer with a significant benefit of financing the transfer of goods
and services. We do not assess whether a contract has a significant financing component if the expectation at contract
inception is such that the period between payment by the licensees and the transfer of the promised goods or services to the
licensees will be one year or less. We assess each of its revenue generating arrangements in order to determine whether a
significant financing component exists. We recognize as revenue the amount of the transaction price that is allocated to the
respective performance obligation when (or as) each performance obligation is satisfied, either at a point in time or over time.
For performance obligations satisfied over time, we measure progress toward completion of its performance obligations using
an input method based on our efforts and inputs to satisfy its performance obligations relative to total expected inputs to the
satisfaction of that performance obligation.

Amounts received from a customer prior to revenue recognition are recorded as deferred revenue. Amounts received

from a customer that are expected to be recognized as revenue within the 12 months following the balance sheet date are
classified as a current liability in the accompanying consolidated balance sheets.

Accrued research and development expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued

research and development expenses. This process involves reviewing open contracts and purchase orders, communicating
with our personnel to identify services that have been performed on our behalf, and estimating the level of service performed
and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual
costs. Most of our service providers invoice us in arrears for services performed, on a pre-determined schedule or when
contractual milestones are met; however, some require advance payments. We make estimates of our accrued expenses as of
each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time.
Examples of estimated accrued research and development expenses include fees paid to the following:

•

CROs and other third parties in connection with performing research and development activities and conducting
preclinical studies and clinical trials on our behalf;

103

•

•

Vendors in connection with preclinical development activities; and

CMOs and other vendors in connection with product manufacturing and development and distribution of
preclinical supplies.

We base our expenses related to preclinical studies on our estimates of the services received and efforts expended

pursuant to quotes and contracts with CROs that conduct and manage preclinical studies and clinical trials and CMOs that
manufacture product for our research and development activities on our behalf. The financial terms of these agreements are
subject to negotiation, vary from contract to contract, and may result in uneven payment flows. There may be instances in
which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. In
accruing fees, we estimate the time period over which services will be performed and the level of effort to be expended in
each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the
accrual or amount of prepaid expense accordingly. Although we do not expect our estimates to be materially different from
amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and
timing of services performed may vary and may cause us to report amounts that are too high or too low in any particular
period. To date, we have not made any material adjustments to our prior estimates of accrued research and development
expenses.

Leases

The Company elected to early adopt ASC 842, Leases, as of January 1, 2020 and elected the transition method under
ASU 2016-02 whereby the Company records a right-to-use asset and a lease liability on the consolidated balance sheet for all
leases with terms longer than 12 months. The Company also elected to apply the package of practical expedients intended to
ease transition. Accordingly, the Company has only applied ASC 842 to leases existing at January 1, 2020. The Company
determines if an arrangement is, or contains, a lease at inception. Operating leases are included in operating lease right-of-
issue (“ROU”) assets, other current liabilities, and operating lease liabilities on the consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent

the Company’s obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the
lease commencement date based on the present value of lease payments to be made over the lease term. The ROU asset also
includes any lease payments made at or before the lease commencement date and excludes lease incentives received. As the
Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information
available at the lease commencement date in determining the present value of lease payments. The lease terms may include
options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating
lease expense is recognized on a straight-line basis over the lease term. The Company has elected to not apply the recognition
requirements of ASC 842 for short-term leases, which is defined as a lease that, at the lease commencement date, has a lease
term of 12 months or less and does not include an option to purchase the underlying asset that the Company is reasonably
certain to exercise.

For real estate lease agreements entered into or modified after the adoption of ASC 842 that include lease and non-

lease components, the Company has elected to account for the lease and non-lease components, such as common area
maintenance charges, as a single lease component.

Stock-based compensation

We measure stock options and other stock-based awards granted to our employees, directors, consultants, advisors

based on the fair value on the date of the grant, awards, net of actual forfeitures, over the requisite service period, which is
generally the vesting period of the respective award. For stock-based awards granted to non-employees, compensation
expense is recognized over the period during which services are rendered by such non-employees until completed.

We estimate the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing
model, which uses as inputs the fair value of our common stock and assumptions we make for the volatility of our common
stock, the expected term of our stock options, the risk-free interest rate for a period that approximates the expected term of
our stock options, and our expected dividend yield.

104

Determination of fair value of common stock

Prior to the IPO, there had been no public market for our common stock and as such, the estimated fair value of our

common stock had been determined by our board of directors as of the date of each option grant, with input from
management, taking into consideration our most recently available third-party valuations of common stock at the time of the
grants, as well as our board of directors’ assessment of additional objective and subjective factors that it believed were
relevant and which may have changed from the date of the most recent valuation through the date of the grant. Third-party
valuations, or valuation reports, were performed in accordance with the guidance outlined in the American Institute of
Certified Public Accountants’ Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity Securities
Issued as Compensation.

Our common stock valuation reports were prepared using a market approach, utilizing either the guideline M&A or

guideline public company methodologies. Under the guideline M&A methodology, a set of mergers and acquisitions within
the biotechnology and pharmaceutical industries for similar stage companies were reviewed and an applicable equity value
was selected to apply to our company. Under the guideline public company methodology, the market capitalizations of
similar public companies were analyzed, and an applicable capitalization for our company was selected based on qualitative
and quantitative factors.

For each valuation report, an option pricing allocation method, or OPM, was selected to allocate the total equity value
across the various securities outstanding at the time of the valuation. The OPM treats common stock and preferred stock as
call options on the total equity value of a company, with exercise prices based on the value thresholds at which the allocation
among the various holders of a company’s securities changes.

In addition to considering the results of the valuation reports, our board of directors considered various objective and

subjective factors to determine the fair value of our common stock as of each grant date, including:

•

•

•

•

•

•

•

•

the prices at which we sold shares of convertible preferred stock and the superior rights and preferences of the
convertible preferred stock relative to our common stock at the time of each grant;

the progress of our research and development programs, including the status and results of preclinical studies and
clinical trials for our product candidates;

our stage of development and commercialization and our business strategy;

external market conditions affecting the biotechnology industry and trends within that industry;

our financial position, including cash on hand, and our historical and forecasted performance and operating
results;

the lack of an active public market for our common stock and our convertible preferred stock;

the likelihood of achieving a liquidity event, such as an initial public offering, or IPO, or sale of our company
considering prevailing market conditions; and

the analysis of IPOs and the market performance of similar companies in the biotechnology industry.

The assumptions underlying these valuations represented management’s best estimate, which involved inherent
uncertainties and the application of management’s judgment. As a result, if we had used different assumptions or estimates,
the fair value of our common stock and our stock-based compensation expense could have been materially different.

Recent accounting pronouncements

A description of recent accounting pronouncements that may potentially impact our financial position, results of

operations, or cash flows is disclosed below:

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement

of Credit Losses on Financial Instruments. The FASB has subsequently issued amendments to ASU 2016-13, which have the
same effective date and transition date. These standards require that credit losses be reported using an expected losses model
rather than the incurred losses model that was previously used, and establishes additional disclosures related to credit risks.
For available-for-sale debt securities with unrealized losses, this standard now requires allowances to be recorded instead of
reducing the amortized cost of the investment. These standards limit the amount of credit losses to be recognized for
available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the reversal of

105

previously recognized credit losses if fair value increases. This standard will become effective for the Company on January 1,
2023. The Company is still evaluating the impact of this standard on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12 amending accounting guidance that simplifies the accounting for

income taxes, as part of its initiative to reduce complexity in the accounting standards. The amendments eliminate certain
exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim
period and the recognition of deferred tax liabilities for outside basis differences. The amendments also clarify and simplify
other aspects of the accounting for income taxes. This standard will become effective for the Company on January 1, 2021.
The Company is still evaluating the impact of this standard on its consolidated financial statements.

There are no other recent accounting pronouncements that we believe will have a material impact on our consolidated

financial statements.

Off-balance sheet arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as

defined under SEC rules.

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

We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate
sensitivities. Our interest-earning assets consist of cash, cash equivalents and short-term investments, which are denominated
in U.S. dollars. We had cash, cash equivalents and short-term investments of $220.3 million, or 83.2% of our total assets, at
December 31, 2020. Interest income earned on these assets was $1.0 million for the year ended December 31, 2020. Our
interest income is sensitive to changes in the general level of interest rates, primarily U.S. interest rates. Such interest-earning
instruments carry a degree of interest rate risk however, if a change by 10% in interest rates were to have immediately
occurred on December 31, 2020, such change would not have had a material impact on our financial position or results of
operations. We had $15.0 million of debt outstanding as of December 31, 2020.

Item 8. Financial Statements and Supplementary Data.

Our consolidated financial statements, together with the reports of our independent registered public accounting firms,

appear at pages F-1 through F-33 of this Annual Report on Form 10-K for the year ended December 31, 2020. An index of
those financial statements is found in Item 15 of Part IV of this Annual Report on Form 10-K.

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

None

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities

Exchange Act of 1934, as amended, or the Exchange Act, that are designed to ensure that information required to be
disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported
within the time periods specified in the Securities and Exchange Commission’s rules and forms and (2) accumulated and
communicated to our management, including our principal executive and principal financial officer, as appropriate to allow
timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how
well designed and operated, can provide only reasonable assurance of achieving their objectives and our management
necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our disclosure
controls and procedures are designed to provide reasonable assurance of achieving their control objectives.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer (our principal
executive officer and principal financial officer, respectively), evaluated the effectiveness of our disclosure controls and
procedures as of December 31, 2020. Based on the evaluation of our disclosure controls and procedures as of December 31,
2020, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and
procedures were effective at the reasonable assurance level.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as

such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Because of its inherent limitations, internal
control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness
to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the
degree of compliance with policies or procedures may deteriorate. Our internal control over financial reporting is a process
designed under the supervision of our principal executive officer and principal financial officer to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting
purposes in accordance with U.S. generally accepted accounting principles.

Our management, with the participation of Chief Executive Officer and Chief Financial Officer (our principal
executive officer and principal financial officer, respectively), conducted an evaluation of the effectiveness of our internal
control over financial reporting based on the criteria set forth in “Internal Control –Integrated Framework (2013)” issued by
the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded
that our internal control over financial reporting was effective as of December 31, 2020.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the period covered by this
Annual Report on Form 10-K that has materially affected, or is reasonably likely to materially affect, our internal control
over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Frequency Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Frequency Therapeutics, Inc. and its subsidiaries

(the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive loss,
convertible preferred stock, non-controlling interest, and stockholders’ equity (deficit) and cash flows for the years then
ended, and the related notes to the consolidated financial statements (collectively, 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,
2020 and 2019, and the results of its operations and its cash flows for the years then ended, 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 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 2017.

Frequency Therapeutics, Inc.

Notes to Consolidated Financial Statements

(Amounts in thousands, except share and per share amounts)

1. Organization and basis of presentation

Frequency Therapeutics, Inc., together with its wholly owned subsidiaries, Frequency Therapeutics, PTY, LTD,
Frequency Therapeutics Securities Corporation and Frequency Therapeutics Japan KK (Frequency Japan) (the Company),
headquartered in Woburn, Massachusetts, was incorporated in November 2014 as a Delaware corporation. The Company is a
clinical-stage biotechnology company focused on harnessing the body’s innate biology to repair or reverse damage caused by
a broad range of degenerative diseases.

On September 20, 2019, the Company effected a 1-for-6.7355 reverse stock split of its common stock. The par value of

the common stock was not adjusted as a result of the reverse stock split and the authorized capital was amended to
100,000,000 shares of common stock and 148,724,922 shares of $0.001 par value preferred stock (the Preferred Stock). The
reverse stock split resulted in an adjustment to the Series A Convertible Preferred Stock (Series A Preferred), Series B
Convertible Preferred Stock (Series B Preferred) and Series C Convertible Preferred Stock (Series C Preferred) conversion
prices to reflect a proportional decrease in the number of shares of common stock to be issued upon conversion. The
accompanying consolidated financial statements and notes to the consolidated financial statements give retroactive effect to
the reverse stock split for all periods presented. Shares of common stock underlying outstanding stock options were
proportionately reduced and the respective exercise prices, if applicable, were proportionately increased in accordance with
the terms of the appropriate securities agreements.

In October 2019, the Company completed the initial public offering of its common stock (the “IPO”). In the IPO, the
Company issued and sold 6,325,000 shares of its common stock at a price to the public of $14.00 per share, inclusive of the
underwriters’ exercise in part of their over-allotment option. The Company received approximately $79.7 million in net
proceeds, after deducting underwriting discounts and commissions and other offering expenses. In connection with the IPO,
on October 7, 2019 all Preferred Stock and the preferred stock of Frequency Japan converted into 22,077,627 shares of
common stock and all outstanding shares of Series A-1 Preferred Stock and B-1 Preferred Stock were forfeited.

On July 20, 2020, the Company issued and sold an aggregate of 2,350,108 shares of its common stock, par value
$0.001 per share, at a purchase price of $18.00 per share to new and existing investors in a private placement for net proceeds
of $40.1 million after deducting placement agent fees and offering expenses (the “Private Placement”). In connection with the
Private Placement, the Company entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with
the investors. Pursuant to the Registration Rights Agreement, the Company agreed to prepare and file a registration statement
with the Securities and Exchange Commission (the “SEC”) within 60 days after the closing of the Private Placement (the
“Initial Filing Date”) for purposes of registering the resale of the Shares. The Company filed a registration statement (the
“Registration Statement”) which was declared effective by the SEC on September 3, 2020.

The Company has also agreed, among other things, to indemnify the investors, their officers, directors, managers,

employees, agents and any person who controls any investor under the Registration Statement from certain liabilities and to
pay all fees and expenses (excluding any underwriting discounts and commissions) incident to the Company’s obligations
under the Registration Rights Agreement.

Uncertainties

The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry,

including, but not limited to, development by competitors of new technological innovations, dependence on key personnel,
protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to
fund operations. Product candidates currently under development will require significant additional research and
development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization. These
efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-
reporting capabilities. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the
Company will realize revenue from product sales.

Our offices are located in states that are currently operating under a phased re-opening plan in response to the COVID-
19 pandemic. As of the date of the filing of this Annual Report, the majority of our employees continue to work from home,

F-8

while nearly a quarter to one-third of our workforce, consisting of mainly laboratory personnel, have periodically worked in
rotating teams to ensure the continuation of essential experiments. Our Farmington, CT research site, co-located with the
University of Connecticut, has resumed activity at a fifty percent level after a period of paused activity due to state lock down
orders previously in effect. While we have resumed experiments at our Farmington site, we have transitioned certain key
experiments to our offices in Woburn, MA and third parties and contract research organizations have been engaged to
advance certain projects. We are also have taken steps consistent with the FDA’s updated industry guidance for conducting
clinical trials.

The COVID-19 pandemic, and actions taken to mitigate it, have had and are expected to continue to have an adverse

impact on the economies and financial markets of many countries, including the geographical area in which we operate,
which could adversely impact our ability to raise additional capital when needed or on acceptable terms, if at all. In addition,
while no significant disruptions have occurred, the COVID-19 pandemic may cause such disruptions in our business or
operations, as well as the business and operations of our CMOs, CROs and other third parties with whom we conduct
business. The COVID-19 pandemic may also adversely impact the our clinical trials, which could impede, delay, limit or
prevent the clinical development of our product candidates and ultimately lead to the delay or denial of regulatory approval of
our product candidates, which would materially adversely affect our business and operations, including our ability to generate
revenue.

Liquidity and capital resources

The Company has funded its operations primarily with proceeds from the sale of its capital stock, convertible notes and

amounts received under a collaboration agreement. The Company has incurred recurring losses since its inception. In
addition, as of December 31, 2020, the Company had an accumulated deficit of $95,399. The Company expects to continue
to generate operating losses for the foreseeable future. The future viability of the Company is dependent on its ability to raise
additional capital to finance its operations. The Company’s inability to raise capital as and when needed could have a
negative impact on its financial condition and ability to pursue its business strategies. There can be no assurances that
additional funding will be available on terms acceptable to the Company, or at all. The Company believes that existing
resources will be sufficient to fund planned operations for at least 12 months from the date the financial statements were
available to be issued.

2. Summary of significant accounting policies

Basis of presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting standards set

by the Financial Accounting Standards Board (FASB). The FASB sets generally accepted accounting principles (GAAP) that
the Company follows to ensure its financial condition, results of operations, and cash flows are consistently reported.
References to GAAP issued by the FASB in these notes to the consolidated financial statements are to the FASB Accounting
Standards Codification (ASC).

Principles of consolidation

The consolidated financial statements include the accounts of Frequency Therapeutics, Inc. and its wholly owned

subsidiaries Frequency Therapeutics Securities Corporation, Frequency Therapeutics PTY, LTD and Frequency Japan. All
intercompany transactions and balances have been eliminated. Frequency Japan was closed down in February 2021, as
further described in Note 19 of notes to consolidated financial statements.

Use of estimates

The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to

make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related
disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of
expenses during the reporting period. On an ongoing basis, the Company’s management evaluates its estimates, which
include but are not limited to management’s judgments of accrued expenses, revenue recognition, fair value of common
stock, valuation of share-based awards, present value of lease liabilities and income taxes. Actual results could differ from
those estimates.

F-9

The Company utilized significant estimates and assumptions in determining the fair value of its common stock in

periods prior to the IPO. The Company utilized various valuation methodologies in accordance with the framework of the
American Institute of Certified Public Accountants Technical Practice Aid, Valuation of Privately Held Company Equity
Securities Issued as Compensation (the Practice Aid), to estimate the fair value of its common stock. Each valuation
methodology includes estimates and assumptions that require the Company’s judgment. These estimates and assumptions
include a number of objective and subjective factors, including external market conditions, the prices at which the Company
sold shares of preferred stock, the superior rights and preferences of securities senior to the Company’s common stock at the
time of, and the likelihood of, achieving a liquidity event, such as an initial public offering or sale. Significant changes to the
key assumptions used in the valuations could have resulted in different fair values of common stock at each valuation date.

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. Other 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).
Comprehensive loss includes net loss as well as other changes in stockholders’ equity that result from transactions and
economic events other than those with stockholders which for the years ended December 31, 2020 and 2019 consist of
unrealized gain on marketable securities.

Segment information

Operating segments are defined as components of an enterprise about which separate discrete information is available

for evaluation by the chief operating decision-maker in deciding how to allocate resources and assess performance. The
Company and the Company’s chief operating decision-maker, the Company’s chief executive officer, views the Company’s
operations and manages its business as a single operating segment, which is in the business of discovering and developing
small molecule drugs that activate progenitor cells within the body to create healthy tissue.

Foreign currency

All periods presented are reported in US dollars. The functional currency for entities outside the United States is the US

dollar. Realized and unrealized gains and losses from foreign currency transactions are reflected in the consolidated
statements of operations as other expense. During the years ended December 31, 2020 and 2019 the Company recorded $(4),
and $7 of foreign currency exchange (losses) gains, respectively.

Cash and cash equivalents

The Company considers all highly liquid investments with an original maturity of six months or less at acquisition to

be cash equivalents which are stated at fair market value. Cash and cash equivalents at December 31, 2020 and 2019 consists
entirely of cash and money market funds.

Restricted Cash

The Company has $1.8 million of restricted cash as of December 31, 2020 which represents a $1.7 million security

deposit on the Company's future Lexington, Massachusetts facility and a $0.1 million security deposit on the Company's
Woburn, Massachusetts facility. The $0.1 million restricted cash at December 31, 2019 represented the security deposit on
the Company's Woburn, Massachusetts facility.

Short-term marketable debt securities

Short-term marketable securities represent holdings of available-for-sale marketable debt securities in accordance with

the Company’s investment policy. Short-term marketable investments mature within one-year from the balance sheet date.
Investments in marketable securities are recorded at fair value, with any unrealized gains and losses reported within
accumulated other comprehensive income as a separate component of stockholders’ equity (deficit) until realized or until a
determination is made that an other-than-temporary decline in market value has occurred. The amortized cost of debt
securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion,
together with interest on securities sold is determined based on the specific identification method and any realized gains or
losses on the sale of investment are reflected as a component of other income (expense).

F-10

Concentration of credit risk and off-balance sheet risk

Financial instrument that potentially expose the Company to concentrations of credit risk consist primarily of cash and

cash equivalents and marketable securities. The Company maintains its cash and cash equivalents at several accredited
financial institutions, in amounts that exceed federally insured limits. Marketable securities consist of U.S. Treasury
securities with maturities of less than twelve months. Management believes that the Company is not exposed to significant
credit risk due to the financial position of the depository institutions in which its money market accounts are maintained.

The Company has no significant off-balance sheet such as foreign exchange contracts, option contracts, or other

foreign hedging arrangements.

Significant suppliers

The Company is dependent on third-party manufacturers to supply products for research and development activities of
its programs, including preclinical and clinical testing. In particular, the Company relies and expects to continue to rely on a
single manufacturer of its product candidates for use in clinical trials. The Company would be adversely affected by a
significant interruption in the supply of product for use in clinical programs.

Fair value measurements

Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability between
market participants at measurement dates. ASC Topic 820, Fair Value Measurement (ASC 820), establishes a three-level
valuation hierarchy for instruments measured at fair value. The hierarchy is based on the transparency of inputs to the
valuation of an asset or liability as of the measurement date. The hierarchy defines three levels of valuation inputs, of which
the first two are considered observable and the last is considered unobservable:

Level 1

Quoted prices in active markets for identical assets or liabilities.

Level 2

Level 3

Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable,
such as quoted market prices, interest rates and yield curves.

Unobservable inputs developed using estimates or assumptions developed by the Company, which reflect
those that a market participant would use in pricing the asset or liability.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the

determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in
determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value
hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The carrying values of other current assets, accounts payable, and accrued expenses approximate their fair values due
to the short-term nature of these assets and liabilities. The fair value of the Company’s Term Loan is not materially different
from the carry value as presented given the Term Loan was issued within one month of December 31, 2020.

Property and equipment

Property and equipment consist of lab equipment, computer equipment, furniture and office equipment and leasehold
improvements recorded at cost. These amounts are depreciated using the straight-line method over the estimated useful lives
of the assets as follows:

Lab equipment
Software
Furniture and office equipment
Leasehold improvements

Estimated useful life

3 years
3 years
3 years
Shorter of the estimated useful
life or lease term

Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from

the balance sheet and related gains or losses are reflected in the consolidated statements of operations.

F-11

Impairment of long-lived assets

The Company continually evaluates long-lived assets for potential impairment when events or changes in

circumstances indicate the carrying value of the assets may not be recoverable. Recoverability is measured by comparing the
book values of the assets to the expected future net undiscounted cash flows that the assets are expected to generate. If such
assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the book values of
the assets exceed their fair value. The Company did not recognize any impairment losses for the years ended December 31,
2020 and 2019.

Research and development costs and accruals

Research and development expenses include salaries and benefits, materials and supplies, preclinical and clinical trial
expenses, stock-based compensation expense, depreciation of equipment, contract services and other outside expenses. The
Company has entered into various research and development-related contracts with research institutions, contract research
organizations, contract manufacturers and other companies. These agreements are generally cancelable, and related payments
are recorded as research and development expenses as incurred. Costs of certain development activities, such as
manufacturing, pre-clinical and clinical trial expenses, are recognized based on an evaluation of the progress to completion of
specific tasks. Payments for these activities are based on the terms of the individual arrangements, which may differ from the
pattern of costs incurred, and are reflected in the consolidated financial statements as prepaid or accrued research and
development costs. Nonrefundable advance payments for goods or services to be received in the future for use in research
and development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are
delivered or the services are performed. Costs incurred in obtaining technology licenses are charged to research and
development expense as acquired in-process research and development if the technology licensed has not reached
technological feasibility and has no alternative future use.

Leases

The Company elected to early adopt ASC 842, Leases (ASC 842) as of January 1, 2020 and elected the transition

method under ASU 2016-02 whereby the Company records a right-to-use asset and a lease liability on the consolidated
balance sheet for all leases with terms longer than 12 months. The Company also elected to apply the package of practical
expedients intended to ease transition. Accordingly, the Company has only applied ASC 842 to leases existing at January 1,
2020. The Company determines if an arrangement is, or contains, a lease at inception. Operating leases are included in
operating lease right-of-issue (“ROU”) assets, other current liabilities, and operating lease liabilities on the consolidated
balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent
the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at
the lease commencement date based on the present value of lease payments to be made over the lease term. The ROU asset
also includes any lease payments made at or before the lease commencement date and excludes lease incentives received. As
the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the
information available at the lease commencement date in determining the present value of lease payments. The lease terms
may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.
Operating lease expense is recognized on a straight-line basis over the lease term. The Company has elected to not apply the
recognition requirements of ASC 842 for short-term leases, which is defined as a lease that, at the lease commencement date,
has a lease term of 12 months or less and does not include an option to purchase the underlying asset that the Company is
reasonably certain to exercise.

For real estate lease agreements entered into or modified after the adoption of ASC 842 that include lease and non-

lease components, the Company has elected to account for the lease and non-lease components, such as common area
maintenance charges, as a single lease component.

Collaborative arrangements

The Company analyzes its collaborative arrangements to assess whether they are within the scope of ASC 808,
Collaborative Arrangements (“ASC 808”) to determine whether such arrangements involve joint operating activities
performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent
on the commercial success of such activities. This assessment is performed throughout the life of the arrangement based on
changes in the responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of ASC 808
that contain multiple elements, the Company first determines which elements of the collaboration are deemed to be within the
scope of ASC 808 and those that are more reflective of a vendor-customer relationship (e.g., a licensing arrangement) where
the contracted party has obtained goods or services that are an output of the Company’s ordinary activities in exchange for a
consideration and therefore within the scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”). For those

F-12

elements of the arrangement that are accounted for pursuant to ASC 606, including those to which ASC 606 is applied by
analogy, the Company applies the five-step model described in the Company’s revenue recognition policy. For elements of
collaborative arrangements that are accounted for pursuant to ASC 808, an appropriate and rational recognition method is
determined and applied consistently. Reimbursements from the counterparty that are the result of a collaborative relationship
with the counterparty, instead of a customer relationship, such as co-development or clinical activities, are recorded as a
reduction to research and development expense as the services are performed. Similarly, amounts that are owed to a
collaboration partner related to the co-development clinical activities are recognized as research and development expense.

The Company enters into out-licensing agreements that are within the scope of ASC 606. The terms of such out-license

agreements include licenses to functional intellectual property (IP), given the functionality of the intellectual property is not
expected to change substantially as a result of the licensor’s ongoing activities. Such arrangements typically include payment
of one or more of the following: non-refundable up-front license fees; reimbursement of certain costs; development and
regulatory milestone payments and milestone payments based on the level of sales; and royalties on net sales of licensed
products.

The Company considers the economic and regulatory characteristics of the licensed IP, research, development,
manufacturing and commercialization capabilities of the licensee and the availability of the associated expertise in the
general marketplace to determine if it has standalone value at the inception of the licensing arrangement, which would make
the license distinct. In addition, the Company considers whether the licensee can benefit from a promise for its intended
purpose without the receipt of any additional good or services promised in the contract, whether the value of the license is
dependent on the remaining goods and services, whether there are other vendors that could provide the remaining promise,
and whether the license is separately identifiable from the remaining good and services. For licenses that are combined with
other goods and services, the Company utilizes judgment to assess the nature of the combined performance obligation to
determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the
appropriate method of measuring progress for purposes of recognizing revenue. The Company evaluates the measure of
progress each reporting period and, if necessary, adjusts the measure of progress and related revenue recognition. The
measure of progress, and thereby periods over which revenue should be recognized, are subject to estimates by management
and may change over the course of the research and development and licensing agreement. Such a change could have a
material impact on the amount of revenue the Company records in future periods.

Revenue is allocated to the licensed IP on a relative standalone selling price basis and, for functional IP, is recognized
at a point when the licensed IP is made available for the customer’s use and benefit, which generally occurs at the inception
of the arrangement. However, in cases, where the functionality of the IP is expected to substantively change as a result of
activities of the Company that do not transfer additional promised goods or services, or in cases, where there is an
expectation that the Company will undertake activities to change the standalone functionality of the IP and the customer is
contractually or practically required to use the latest version of the IP, revenue for the license to functional IP is recognized
over time.

Development and regulatory milestone fees, which are a type of variable consideration, are recognized as revenue to
the extent that it is probable that a significant reversal will not occur. The Company recognizes royalty revenue and sales-
based milestones at the later of (i) when the related sales occur, or (ii) when the performance obligation to which the royalty
has been allocated has been satisfied.

The Company has entered into a collaboration arrangement with Astellas Pharma Inc. (“Astellas”), as further described

in Note 16 of notes to consolidated financial statements.

Revenue recognition

The Company accounts for contracts with customers in accordance with ASC 606, including all amendments thereto.

This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as
collaborative arrangements and leases. The Company’s disclosure within the below sections or elsewhere within these
consolidated financial statements reflects the Company’s accounting policies in compliance with this new standard.

Under ASC 606, an entity recognizes revenue when or as its customer obtains control of promised goods or services, in

an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To
recognize revenue for arrangements that an entity determines are within the scope of ASC 606, the entity performs the
following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract;
(iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the
performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies its performance
obligations. The Company only applies the five-step model to contracts when it is probable that the entity will collect
substantially all of the consideration to which it will be entitled in exchange for the goods or services it transfers to the
customer. Once a contract is determined to be within the scope of ASC 606, the Company assesses the goods or services
promised within each contract and identifies as a performance obligation each promise to transfer to the customer either (a) a

F-13

good or service (or bundle of goods and services) that is distinct, or (b) a series of distinct goods and services that are
substantially the same and have been the same pattern of transfer to the customer.

The Company assesses whether each promised good or service is distinct for the purpose of identifying the
performance obligations in the contract. This assessment involves subjective determinations and requires management to
make judgments about the individual promised goods or services and whether such are separable from the other aspects of
the contractual relationship. Promised goods and services are considered distinct provided that: (i) the customer can benefit
from the good or service either on its own or together with other resources that are readily available to the customer (that is,
the good or service is capable of being distinct) and (ii) the entity’s promise to transfer the good or service to the customer is
separately identifiable from other promises in the contract (that is, the promise to transfer the good or service is distinct
within the context of the contract). In assessing whether a promised good or service is distinct, the Company considers
factors such as the research, manufacturing and commercialization capabilities of the collaboration partner (the “customer” in
this type of arrangement) and the availability of the associated expertise in the general marketplace. The Company also
considers the intended benefit of the contract in assessing whether a promised good or service is separately identifiable from
other promises in the contract. If a promised good or service is not distinct, an entity is required to combine that good or
service with other promised goods or services until it identifies a bundle of goods or services that is distinct. For each
arrangement that results in revenues, the Company identifies all performance obligations, which may include, for example, a
license to IP and know-how, research and development activities, and/or manufacturing services.

In addition to any upfront payment, if the consideration promised in a contract includes a variable amount, the
Company estimates the amount of consideration to which it will be entitled in exchange for transferring the promised goods
or services to a customer. The Company determines the amount of variable consideration by using the expected value method
or the most likely amount method. The Company includes the estimated variable consideration in the transaction price to the
extent it is probable that a significant reversal of cumulative revenue recognized will not occur. At the end of each subsequent
reporting period, the Company re-evaluates the estimated variable consideration included in the transaction price and any
related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on
a cumulative catch-up basis in the period of adjustment.

If an arrangement includes development and regulatory milestone payments, the Company evaluates whether the
milestones are considered probable of being reached and estimates the amount to be included in the transaction price using
the most likely amount method. There is considerable judgment involved in determining whether it is probable that a
significant revenue reversal would not occur. If it is probable that a significant revenue reversal will not occur, the associated
milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or of
the licensee such as regulatory approvals, are generally not considered probable of being achieved until those approvals are
received. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of all
milestones subject to constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments
are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

For contracts that include sales-based royalties (including milestone payments based on the level of sales) promised in
the exchange for licenses of intellectual property, and the license is deemed to be the predominant item to which the royalties
relate, the Company recognizes royalty revenue and sales-based milestone payments at the later of (i) when the related sales
occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied. In
determining the transaction price, the Company adjusts the promised amount of consideration for the effects of the time value
of money if the timing of payments provides the Company or the Company’s customer with a significant benefit of financing
the transfer of goods and services. The Company does not assess whether a contract has a significant financing component if
the expectation at contract inception is such that the period between payment by the licensees and the transfer of the promised
goods or services to the licensees will be one year or less. The Company assesses each of its revenue generating arrangements
in order to determine whether a significant financing component exists. The Company recognizes as revenue the amount of
the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is
satisfied, either at a point in time or over time. For performance obligations satisfied over time, the Company measures
progress toward completion of its performance obligations using an input method based on the Company’s efforts and inputs
to satisfy its performance obligations relative to total expected inputs to the satisfaction of that performance obligation.

Amounts received from a customer prior to revenue recognition are recorded as deferred revenue. Amounts received

from a customer that are expected to be recognized as revenue within the 12 months following the balance sheet date are
classified as a current liability in the accompanying consolidated balance sheets.

F-14

Patent costs

The Company expenses patent application and related legal costs as incurred and classifies such costs as general and

administrative expenses in the accompanying consolidated statements of operations.

Stock-based compensation

The Company accounts for its stock-based compensation in accordance with ASC Topic 718, Compensation—Stock

Compensation (ASC 718). ASC 718 requires all share-based payments to employees and directors to be recognized as
expense in the consolidated statements of operations and comprehensive loss based on their grant date fair values. The
Company adopted FASB Accounting Standards Update (ASU) 2016-09 which identifies areas for simplification of several
areas of share-based payment transactions. The Company treats non-employee grants in a manner consistent with employee
grants. The Company estimates the fair value of options granted using the Black-Scholes option pricing model for stock
option grants to both employees and non-employees. The Company believes the fair value of the stock options granted to
non-employees is more reliably determinable than the fair value of the services provided.

The Black-Scholes option pricing model requires inputs based on certain subjective assumptions, including (a) the

expected stock price volatility, (b) the expected term of the award, (c) the risk-free interest rate and (d) expected dividends.
Due to the lack of sufficient company-specific historical and implied volatility data, the Company has based its computation
of expected volatility on the historical volatility of a representative group of public companies with similar characteristics to
the Company, including stage of product development and life science industry focus. The historical volatility is calculated
based on a period of time commensurate with the expected term assumption. The Company uses the simplified method as
prescribed by the SEC Staff Accounting Bulletin No. 107, Share-Based Payment, to calculate the expected term for options
granted to employees as it does not have sufficient historical exercise data to provide a reasonable basis upon which to
estimate the expected term. The expected term is applied to the stock option grant group as a whole, as the Company does not
expect substantially different exercise or post-vesting termination behavior among its employee population. For options
granted to non-employees, the Company utilizes the contractual term of the share-based payment as the basis for the expected
term assumption. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected term
of the stock options. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no
current plans to pay any dividends on its common stock.

There are significant judgments and estimates inherent in the determination of the fair value of the Company’s

common stock prior to the IPO. These estimates and assumptions include a number of objective and subjective factors,
including external market conditions, the prices at which the Company sold shares of preferred stock, the superior rights and
preferences of securities senior to its common stock at the time of, and the likelihood of, achieving a liquidity event, such as
an initial public offering or sale.

The Company expenses the fair value of its share-based compensation awards to employees and non-employees on a

straight-line basis over the requisite service period, which is generally the vesting period.

Income taxes

The Company accounts for income taxes using the asset and liability method in accordance with ASC Topic 740,
Income Taxes (ASC 740) which requires the recognition of deferred tax assets and liabilities for the expected future tax
consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns.
Deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax basis
of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes
in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that
its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of
available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a
valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is
evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies. At
December 31, 2020 and 2019, the Company has concluded that a full valuation allowance is necessary for its deferred tax
assets (see Note 13).

Net loss per share

Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average
number of shares of common stock outstanding during the period. Diluted net loss per share is computed using the weighted-
average number of shares of common stock outstanding during the period and, if dilutive, the weighted-average number of

F-15

potential shares of common stock. Diluted net loss per share is the same as basic net loss per share for the years ended
December 31, 2020 and 2019 since all potential shares of common stock instruments are anti-dilutive as a result of the loss
for such periods.

The Company’s convertible preferred stock contractually entitled the holders of such shares to participate in dividends
but did not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in
which the Company reported a net loss, such losses are not allocated to such participating securities. In periods where the
Company reported a net loss attributable to common stockholders, diluted net loss per share is the same as basic net loss per
share, since dilutive shares of common stock are not assumed to have been issued if their effect is anti-dilutive. The Company
reported a net loss attributable to common stockholders for the years ended December 31, 2020 and 2019.

Basic and diluted net loss per share attributable to common stockholders was calculated as follows:

Recently adopted accounting pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), as amended by various
subsequently issued ASUs. The standard requires lessees to recognize an operating lease with a term greater than one year on
their balance sheets as a right-of-use asset and corresponding lease liability, measured at the present value of the lease
payments. Lessees are required to classify leases as either finance or operating leases. If the lease is effectively a financed
purchase by the lessee, it is classified as a financing lease, otherwise it is classified as an operating lease. This classification
will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the
term of the lease.

In July 2018, the FASB also issued ASU 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”),

which permits entities to continue applying legacy guidance in ASC 840, Leases, including its disclosure requirements, in the
comparative periods presented in the year that the entity adopts the new leasing standard. The Company adopted the standard
on January 1, 2020 using the optional transition method. As such, the consolidated balance sheets and statements of
operations for prior periods will not be comparable in the year of adoption of ASC 842. The Company elected the package of
practical expedients permitted under the transition guidance within the standard. Accordingly, the Company did not reassess
the conclusion of whether the existing arrangements contain a lease, lease classification and initial direct costs under ASC

F-16

842. As a result of the adoption of ASC 842, the Company recorded $1.2 million of ROU assets and a total of $1.5 million of
lease liabilities on the consolidated balance sheets as of January 1, 2020. In addition, in the first quarter of 2020 the Company
expanded and amended the lease for its Woburn, Massachusetts facility and increased both the ROU asset and lease liability
by $1.0 million. On December 11, 2020, the Company terminated this lease and remeasured the existing ROU asset and lease
liability based on this lease modification, resulting in a $1.7 million impact to both the ROU asset and lease liability. As
disclosed in Note 16, the Company has entered into a lease for a facility in Lexington Massachusetts which commenced
December 11, 2020. In accordance with ASU No. 2016-02, the Company recognized a right-of-use asset and related lease
liability at such time.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10):
Recognition and Measurement of Financial Assets and Financial Liabilities. This new standard amended certain aspects of
accounting and disclosure requirements for financial instruments, including the requirement that equity investments with
readily determinable fair values are to be measured at fair value with any changes in fair value recognized in a company's
statements of operations. Prior to adoption of ASU 2016-01, companies recognized changes in fair value in accumulated
other comprehensive income (loss), net. Equity investments that do not have readily determinable fair values may be
measured at fair value or at cost minus impairment adjusted for changes in observable prices. In addition, a valuation
allowance should be evaluated on deferred tax assets related to available- for-sale debt securities in combination with other
deferred tax assets. The Company adopted this new standard on January 1, 2020, using the modified retrospective method,
and determined that it did not have a material impact on its financial statements.

Recently issued accounting pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and
adopted by the Company as of the specified effective date. The Company is an “emerging growth company” as defined in the
Jumpstart Our Business Startups Act of 2012, as amended (Jobs Act). The Jobs Act provides that an emerging growth
company can take advantage of an extended transition period for complying with new or revised accounting standards. Thus,
an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise
apply to private companies. The Company elected to avail itself of this extended transition period and, as a result, we will not
be required to adopt new or revised accounting standards on the relevant dates on which adoption of such standards is
required for other public companies.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement

of Credit Losses on Financial Instruments. The FASB has subsequently issued amendments to ASU 2016-13, which have the
same effective date and transition date. These standards require that credit losses be reported using an expected losses model
rather than the incurred losses model that was previously used, and establishes additional disclosures related to credit risks.
For available-for-sale debt securities with unrealized losses, this standard now requires allowances to be recorded instead of
reducing the amortized cost of the investment. These standards limit the amount of credit losses to be recognized for
available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the reversal of
previously recognized credit losses if fair value increases. This standard will become effective for the Company on January 1,
2023. The Company is still evaluating the impact of this standard on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12 amending accounting guidance that simplifies the accounting for

income taxes, as part of its initiative to reduce complexity in the accounting standards. The amendments eliminate certain
exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim
period and the recognition of deferred tax liabilities for outside basis differences. The amendments also clarify and simplify
other aspects of the accounting for income taxes. This standard will become effective for the Company on January 1, 2021.
The Company is still evaluating the impact of this standard on its consolidated financial statements.

7. Debt

On December 11, 2020, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with a
commercial bank for a Term Loan with a principal balance of $15 million. The Company will make monthly interest only
payments through November 30, 2022. The principal balance and interest will be repaid in equal monthly installments after
the interest only period and continuing through May 1, 2024 (the “Loan Maturity Date”). Advances under the Loan
Agreement will bear an interest rate equal to the greater of either (i) 1.50% plus the Prime Rate (as reported in The Wall
Street Journal, subject to an interest rate floor of zero) or (ii) 4.75%. Interest related to the Loan Agreement was immaterial
for the year ended December 31, 2020.

The Company may prepay the advance made under the Loan Agreement in whole, at any time subject to a prepayment
premium equal to: (a) 2.0% of the then-outstanding principal amount of the advance, if such prepayment occurs on or prior to
the first anniversary of the Closing Date; (b) 1.0% of the then-outstanding principal amount of the advance, if such
prepayment occurs after the first anniversary of the Closing Date and on or prior to the second anniversary of the Closing
Date; and (c) 0.0% of the then-outstanding principal amount of the advance, if such prepayment occurs after the second
anniversary of the Closing Date. The prepayment premium is waived if the Term Loan Facility is refinanced by the Bank (in
its sole and absolute discretion) on or prior to the Loan Maturity Date.

The Company will pay a final payment of $150,000, which will occur on the earliest of: (i) the Loan Maturity Date;

(ii) the date that the Company prepays all of the outstanding principal in full; (iii) the date the loan payments are accelerated
due to an event of default; or (iv) the termination of the Loan Agreement. The Company is recording the final payment as
interest expense over the term of the loan. The Term Loan Facility is secured by substantially all of the Company’s assets,
excluding intellectual property.

8. Convertible preferred stock

As of December 31, 2018, the Company had issued 62,528,507 shares of Series A Preferred Stock, 10,000 shares of

Series A-1 Preferred Stock, 41,857,005 shares of Series B Preferred Stock, and 10,000 shares of Series B-1 Preferred Stock.
In 2019, the Company also issued 288,911 shares of Series B Preferred Stock. On July 17, 2019, the Company authorized
and issued 39,492,960 shares of Series C Preferred for net proceeds of $61,687.

The Company evaluated the tranched nature of the issuance of these preferred shares as well as the rights, preferences,

and privileges of such shares and has concluded that there were no freestanding derivative instruments or any embedded
derivatives requiring bifurcation.

In October 2019, in connection with the IPO, all shares of Preferred Stock were automatically converted into common

stock.

9. Non-controlling Interest

In 2018, the Company issued shares of preferred stock in its subsidiary, Frequency Japan, to a Japanese investor. The

Frequency Japan preferred stock held by such investor was convertible, at the option of the holder, into 673,605 shares of
Company common stock, adjustable for certain dilutive events, upon an initial public offering of Company common stock, a
Company liquidation or upon a 70% vote of the holders of the Preferred Stock. The preferred shares also had a liquidation
preference equal to the amount paid for the shares. The Company had the option to acquire the preferred shares of Frequency
Japan under certain circumstances and the holder of such preferred shares had the right to require the Company to purchase
such shares under certain circumstances, primarily a merger or liquidation.

In connection with this sale of the preferred stock in Frequency Japan, FT-FJ Investment, LLC (FT-FJ), a Delaware

limited liability company controlled by the Company, purchased 10,000 shares of the Company’s Series A-1 Preferred Stock
and 10,000 shares of the Company’s Series B-1 Preferred Stock. FT-FJ also granted to the Japanese investor an irrevocable
proxy to vote the shares of Series A-1 and Series B-1 Preferred Stock held by FT-FJ. Each share of Series A-1 Preferred had
236 times the voting power of one share of common stock and each share of Series B-1 Preferred Stock has 217 times the
voting power of one share of common stock.

On August 20, 2019, the Company, Frequency Japan, the Japanese investor, and FT-FJ entered into an agreement
pursuant to which, contingent upon the closing of an initial public offering of the Company’s common stock: (i) the Japanese
investor agreed to convert its shares of preferred stock held in Frequency Japan and to terminate its proxy over the shares of
Series A-1 and B-1 Preferred Stock held by FT-FJ and (ii) FT-FJ agreed to forfeit its shares of Series A-1 and Series B-1
Preferred Stock. The shares were converted into common stock and the Series A-1 and B-1 preferred shares were forfeited in
conjunction with the IPO.

11. Stock-based compensation

On November 13, 2014, the Company adopted the 2014 Stock Incentive Plan (2014 Plan). All of the Company’s

employees, officers, directors, and consultants are eligible to be granted options to purchase common shares and restricted
stock under the terms of the 2014 Plan. The Company reserved an aggregate of 8,550,415 shares of common stock for
issuance under the 2014 Plan. As of December 31, 2020, there were no shares of common stock available for future grants
under the 2014 Plan.

On September 17, 2019, the Company’s board of directors and on September 19, 2019, its stockholders approved and
adopted the 2019 Incentive Award Plan (“the “2019 Plan”) which became effective on the day prior to the IPO. Under the
2019 Plan, the Company may grant stock options, stock appreciation rights, restricted stock, restricted stock units, and other
stock and cash-based awards to individuals who are then employees, officers, directors or consultants of the Company, and
employees and consultants of the Company’s subsidiaries. A total of 3,100,000 shares of common stock were approved to be
initially reserved for issuance under the 2019 plan. The number of shares under the 2014 Plan subject to outstanding awards
as of the effective date of the 2019 Plan that are subsequently canceled, forfeited or repurchased by the Company will be
added to the shares reserved under the 2019 Plan. In addition, the number of shares of common stock available for issuance
under the 2019 Plan will be automatically increased on the first day of each calendar year during the ten-year term of the
2019 Plan, beginning with January 1, 2020 and ending with January 1, 2029, by the amount equal to 4% of the outstanding
number of shares of the Company’s common stock on December 31, of the preceding calendar year or such lesser amount as
determined by the Company’s board of directors.

All stock option grants are non-statutory stock options except option grants to employees (including officers and

directors) intended to qualify as incentive stock options under the Internal Revenue Code of 1986, as amended. Incentive
stock options may not be granted at less than the fair market value of the Company’s common stock on the date of grant, as
determined in good faith by the Board of Directors at its sole discretion. Nonqualified stock options may be granted at an
exercise price established by the Board of Directors at its sole discretion (which has not been less than fair market value on
the date of grant) and the vesting periods may vary. Vesting periods are generally four years and are determined by the Board
of Directors. Stock options become exercisable as they vest. Options granted under the 2014 Plan and the 2019 Plan expire
no more than ten years from the date of grant.

Stock option valuation

The assumptions that the Company used to determine the grant-date fair value of stock options granted to employees

and directors were as follows, presented on a weighted average basis:

Risk-free interest rate
Expected term (in years)
Expected volatility
Expected dividend yield

December
31,
2020

December
31,
2019

1.1%
6.0
79.1%
0.0%

2.0%
5.9
79.4%
0.0%

Risk-Fee Interest Rate: The Company based the risk-free interest rate over the expected term of the options based on

the constant maturity of U.S. Treasury securities with similar maturities as of the date of the grant.

Expected Term: The expected term represents the period that the options granted are expected to be outstanding and is

determined using the simplified method (based on the mid-point between the vesting date and the end of the contractual
term).

Expected Volatility: The Company uses an average historical stock price volatility of comparable public companies

within the biotechnology and pharmaceutical industry that were deemed to be representative of future stock price trends as
the Company does not have sufficient trading history for its common stock. The Company will continue to apply this process
until a sufficient amount of historical information regarding volatility of its own stock price options becomes available.

Expected Dividend Yield: The Company has not paid and does not anticipate paying any dividends in the near future.

Therefore, the expected dividend yield was zero.

The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock
options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair
value of the Company’s common stock. During the years ended December 31, 2020 and 2019, 769,385 and 357,170 shares
were exercised, respectively. The aggregate intrinsic value of stock options exercised during the years ended December 31,
2020 and 2019 was $16,667 and $5,896 respectively.

F-21

The weighted-average grant date fair value of options granted to employees during the years ended December 31, 2020

and 2019 was $16.41 and $4.05 respectively.

The total grant date fair value of options vested during the years ended December 31, 2020 and 2019 was $7,907 and

$2,990, respectively.

Restricted common stock

The Company issued common stock to founders, employees and advisors which was subject to vesting over four years.

If any of these individuals ceased to be employed or to provide services to the Company prior to vesting, the Company had
the right to repurchase any unvested Common Stock at the price paid by the holder.

A summary of the status of restricted common stock as of December 31, 2020 and 2019 is presented below:

The total value of restricted stock awards that vested during the years ended December 31, 2020 and 2019, based on

estimated fair values of the stock underlying the restricted stock awards was $20 and $73, respectively.

Stock-based compensation

Stock-based compensation expense of $9,983 and $3,609 for the years ended December 31, 2020 and 2019
respectively, is included in research and development and general and administrative expenses in the Company’s
consolidated statements of operations and comprehensive loss.

As of December 31, 2020 and 2019, total unrecognized stock-based compensation expense relating to unvested stock
options was $31,006 and $13,820, respectively. This amount is expected to be recognized over a weighted-average period of
3.08 years and 2.76 years, respectively.

12. Employee stock purchase plan

On September 20, 2019, the Company’s board of directors and stockholders approved and adopted the 2019 Employee
stock Purchase Plan (the “ESPP”) which became effective on the date of the IPO. The ESPP permits participants to purchase
common stock through payroll deductions of up to 15% of their eligible compensation. A total of 315,000 shares of common
stock were approved to be initially reserved for issuance under the ESPP. In addition, the number of shares of common stock
available for issuance under the ESPP will be automatically increased on the first day of each calendar year during the first
ten-years of the term of the ESPP, beginning with January 1, 2020 and ending with January 1, 2029, by an amount equal to
1% of the outstanding number of shares of the Company’s common stock on December 31 of the preceding calendar year or
such lesser amount as determined by the Company’s board of directors. No shares were issued under the ESPP at December
31, 2020.

F-22

13. Income taxes

Since inception in 2014, the Company has generated cumulative federal and state net operating loss and research and

development credit carryforwards for which we have not recorded any net tax benefit due to uncertainty around utilizing
these tax attributes within the respective carryforward periods.

As of December 31, 2020, the Company had federal net operating loss carryforwards of approximately $67,868 and
Massachusetts state operating loss carryforwards of approximately $43,386 which may be available to offset future taxable
income. The U.S. federal net operating loss carryforwards include $22,400 available to reduce future taxable income through
2037 and approximately $45,469 which do not expire and are available to reduce future taxable income indefinitely. The state
net operating loss carryforwards are available to offset future taxable income through 2040. As of December 31, 2020, the
Company also had federal and Massachusetts research and development tax credit carryforwards of $3,014 and $1,211,
respectively, which are available to offset federal and state tax liabilities through 2040 and 2035, respectively.

Realization of future tax benefits is dependent on many factors, including the Company’s ability to generate taxable

income within the net operating loss carryforward period. Net operating loss and tax credit carryforwards may become
subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant shareholders
over a three-year period in excess of 50%, as provided under Sections 382 and 383 of the Internal Revenue Code of 1986, as
amended, respectively, as well as similar state provisions. These ownership changes may limit the number of carryforwards
that can be utilized annually to offset future taxable income. In general, an ownership change, as defined by Section 382,
results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by
more than 50% over a three-year period. The Company has completed several financings and has conducted a study to assess
whether a change of control has occurred or whether there have been multiple changes of control since inception and has
determined that an ownership change did occur in March 2017. Accordingly, utilization of $12,400 of the U.S. net operating
loss carryforwards which were incurred prior to March 2017 (pre-ownership change) is limited under Section 382. After the
Section 382 limitations, the Company may utilize approximately $10,800 of its pre-ownership change net operating loss
carryforwards based upon an annual usage of approximately $1,600 for each of the next five years after the ownership change
and approximately $180 for each of the 15 years thereafter. The remaining pre-ownership change net operating losses of
approximately $1,600 were written off due to expiration under limitation. The limitation has been determined by first
multiplying the value of our stock at the time of the ownership change by the applicable long-term tax-exempt rate. These
carryforwards may be subject to further annual limitations under Section 382 in the event of future changes in ownership.
Additionally, the Company has determined an ownership changed occurred in October of 2019 as a result of the IPO.
Accordingly, utilization of approximately $46,123 of the U.S. net operating loss carryforwards incurred prior to October
2019 is also limited under Section 382. The Company has determined it will be able to utilize the entire $46,123 of its pre-
ownership change net operating loss carryforwards based upon the limitations calculated from the October 2019 ownership
change. These carryforwards may be subject to further annual limitations under Section 382 in the event of future changes in
ownership.

ASC 740 requires a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the
evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. After consideration
of all the evidence, both positive and negative, the Company has recorded a valuation allowance against its deferred tax
assets at December 31, 2020 and 2019 because the Company’s management has determined that it is more likely than not that
the Company will not recognize the benefits of its federal and state deferred tax assets primarily due to its cumulative loss
position and, as a result, a valuation allowance of approximately $26,995 and $16,204 as of December 31, 2020 and 2019 has
been established.

The Company has no unrecognized tax benefits. The Company has not, as yet, conducted a study of its research and
development credit carryforwards. Such a study may result in an adjustment to the Company’s research and development
credit carryforwards; however, until a study is completed, and any adjustment is known, no amounts are being presented as
an uncertain tax position. A full valuation allowance has been provided against the Company’s research and development
credits and, if an adjustment were required, this adjustment would be offset by an adjustment to the valuation allowance.
Thus, there would be no impact to the consolidated balance sheet or consolidated statements of operations if an adjustment
were required. The Company has elected to recognize interest and penalties related to income tax matters as a component of
income tax expense, of which no interest or penalties were recorded for the years ended December 31, 2020 and 2019.

F-23

The Company files income tax returns in the U.S. and Massachusetts. The statute of limitations for assessment by the

Internal Revenue Service and Massachusetts tax authorities remains open for all years since 2014. To the extent the Company
has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by
the Internal Revenue Service or state authorities to the extent utilized in a future period. No federal or state tax audits are
currently in process.

14. Research and license agreements

Massachusetts Institute of Technology

In December 2016, the Company entered into an exclusive patent license agreement (MIT License Agreement), with

the Massachusetts Institute of Technology, (MIT), under which the Company received an exclusive, worldwide, royalty-
bearing license to certain patent rights to develop, make, have made, use, sell, offer to sell, lease and import products
(Licensed Products) and to develop and perform processes (Licensed Processes) which incorporate the licensed technology
for the treatment of disease, including but not limited to the prevention and remediation of hearing loss. The Company also
has the right to grant sublicenses of its rights under the MIT License Agreement.

The Company is required to use diligent efforts to develop and commercialize the Licensed Products or Processes, and

to make such products or processes reasonably available to the public and to spend certain minimum amounts on research
and development of Licensed Products and/or Processes each year until the first commercial sale of a Licensed Product
and/or a first commercial performance of a Licensed Process. The Company is also subject to certain development
obligations with regards to a first Licensed Product. The Company has satisfied certain obligations related to preclinical
studies and the filing of an IND for a first Licensed Product with its development activities related to FX-322. The
Company’s future development obligations are: (i) to commence a Phase II clinical trial for such Product, (ii) to commence a
Phase III clinical trial for such Product within five years of the IND filing for such product within two years of the IND filing
for such product, (iii) to file a New Drug Application or equivalent with the FDA or comparable European regulatory agency
for such Product within nine years of the IND filing for such product, and (iv) to make a first commercial sale of such
Product within 11 years of the IND filing for such product. The Company also has certain development obligations for as
second Licensed Product. In the event that the Company has failed to fulfill the development timeline obligation with respect
to a second Licensed Product and fail to cure such breach within ninety (90) days of written notice by MIT, MIT may restrict
the licensed field to the prevention and remediation of hearing loss in humans and animals. The Company does not have the
right to control prosecution of the in-licensed patent applications, and its rights to enforce the in-licensed patents are subject
to certain limitations.

Upon entering into the MIT License Agreement, the Company paid a $50 license fee payment and issued to MIT shares

of our common stock equal to 5% of total then-outstanding capital stock. The Company is required to pay certain annual
license maintenance fees which may be credited to running royalties during the same calendar year, if any, and to make
potential milestone payments up to $2,900 on each Licensed Product or Licensed Process. In addition, The Company is
required to pay a low single-digit royalty on Licensed Products and Licensed Processes and a low-twenties royalty on
sublicense revenues. In the year ended December 31, 2019 the Company paid MIT a royalty of $16,000 related to the upfront
payment received from Astellas, see Note 15.

F-25

The MIT License Agreement will remain effect until the expiration or abandonment of all issued patents and filed
patent applications licensed thereunder remain in effect, unless terminated earlier. The Company has the right to terminate for
any reason upon a 3-month prior written notice. MIT shall have the right to terminate if the Company ceases to carry on any
business related to the MIT License Agreement. MIT may terminate the MIT License Agreement for the Company’s material
breach uncured within ninety (90) days (or thirty (30) days in the case of nonpayment). MIT may also terminate the MIT
License Agreement if the Company or our affiliates commence any action against MIT to declare or render any claim of the
licensed patent rights invalid, unpatentable, unenforceable, or non-infringed (a patent challenge), or if our sublicensee
commences such actions and the Company does not terminate such sublicense within thirty (30) days after MIT’s demand.
MIT has the right to increase all payments due, instead of terminating the MIT License Agreement in the case of a patent
challenge.

In May 2019, the Company entered into an amendment with MIT, updating the diligence milestones for a second

Licensed Product.

The patents in-licensed by the Company from MIT pursuant to the MIT License claim inventions created by, among

others, Dr. Langer, one of the Company’s directors. Pursuant to MIT’s policy on the ownership, distribution and commercial
development of MIT technology, or the MIT Policy, inventors of intellectual property invented at MIT, including the
inventors of patents licensed to the Company under the MIT License, are entitled to a portion of the net royalty income
derived by MIT from such inventions, but not amounts received by MIT from the sale of common stock previously issued by
the Company to MIT pursuant to the MIT License. Accordingly, pursuant to the MIT Policy, Dr. Langer is entitled to receive
a portion of the amounts the Company pays to MIT under the MIT License, including the Astellas Royalty Payment and
future milestone payments or royalties, if any, that the Company may receive pursuant to the Astellas Agreement.
Accordingly, Dr. Langer has received $1.98 million and $0.01 million from MIT under the MIT Policy during the years
ended December 31, 2020 and 2019, respectively. Refer to Note 18 for all related party disclosures.

The Scripps Research Institute (California Institute for Biomedical Research)

In September 2018, the Company entered into a license agreement, (CALIBR License Agreement), with the California
Institute for Biomedical Research, (CALIBR), under which the Company received an exclusive, worldwide, royalty-bearing
license to certain patent rights to make, have made, use, sell, offer to sell, and import products (CALIBR Licensed Products)
which incorporate the licensed technology for the treatment of multiple sclerosis. The Company also have the right to grant
sublicenses of our rights under the CALIBR License Agreement. CALIBR reserves the right to use for itself and the right to
grant non-exclusive licenses to other nonprofit or academic institutions, for any internal research and educational purposes.

The Company is required to use commercially reasonable efforts to develop, manufacture, and sell at least one
Licensed Product and does not have the right to control prosecution of the in-licensed patent applications, and to enforce the
in-licensed patents are subject to certain limitations. The Company is also subject to certain milestone timeline obligations ,
which may be extended under certain circumstances as outlined in the CALIBR License Agreement, to: (i) submit an IND (or
equivalent) for a CALIBR Licensed Product by the 30th month after the effective date of the CALIBR License Agreement,
(ii) initiate a Phase II clinical trial (or equivalent) for a CALIBR Licensed Product by the fourth anniversary of the effective
date of the CALIBR License Agreement, and (iii) initiate a Phase III clinical trial (or equivalent) for a CALIBR Licensed
Product by the sixth anniversary of the effective date of the CALIBR License Agreement.

Upon entering into the CALIBR License Agreement, the Company made a $1,000 license fee payment and are required

to make milestone payments up to $26,000 for each Category of CALIBR Licensed Products (Category 1 means any
CALIBR Licensed Products containing a compound that modulates any muscarinic receptor and Category 2 means any
CALIBR Licensed Products not included in Category 1 that could differentiate oligodendrocyte precursors). The Company is
also required to pay a middle single-digit royalty on CALIBR Licensed Products and a royalty on sublicense revenues
ranging from low-teen percentage to 50%.

The CALIBR License Agreement shall continue in effect until expiration of all Company obligations to pay royalties.

Royalties shall be payable on a country-by-country and CALIBR Licensed Product-by-CALIBR Licensed Product basis upon
the later of (1) the expiration or abandonment of all valid claims of the licensed patent rights in such country and (2) ten years
from the first commercial sale of each CALIBR Licensed Product. The Company may terminate the CALIBR License
Agreement at will upon a 30-day prior written notice. The Company may also elect to terminate its license to one or more
licensed patents in any or all jurisdictions by giving ninety (90) days’ prior written notice to CALIBR. CALIBR may
terminate the CALIBR License Agreement for material breach uncured within thirty (30) days. CALIBR has the right to

F-26

terminate or reduce the license to a non-exclusive license if the Company fails to use diligent efforts to develop and
commercially exploit CALIBR Licensed Products.

The Scripps Research Institute

In September 2018, we entered into a Research Funding and Option Agreement, or the Scripps option agreement,
with Scripps, under which we were granted an exclusive option to acquire an exclusive, sublicensable, worldwide license
under certain intellectual property related to the treatment of MS. As consideration for the Scripps option agreement, we
made funding payments totaling $0.7 million to Scripps to support its research activities. Scripps has agreed to use reasonable
efforts to perform the research program pursuant to the Scripps option agreement. The Scripps option agreement had a one-
year term and was renewed for a second year by mutual written agreement.

In September 2020, the Company extended the term of the option agreement through the end of December 2021. As

consideration for this extension, the Company is required to make additional funding payments of $0.6 million to Scripps
through December 2021.

The Company has the right to terminate by giving 90 days’ advance notice. Scripps has the right to terminate in the
event of nonpayment by us that remains uncured for 10 days. Each party has the right to terminate in the event of the other
party’s material breach that remains uncured for 60 days or if the other party becomes bankrupt.

Massachusetts Eye and Ear (Formerly Massachusetts Eye and Ear Infirmary)

In February 2019, the Company entered into an Non-Exclusive Patent License Agreement (MEE License Agreement)
with the Massachusetts Eye and Ear (MEE) under which it received a non-exclusive, non-sublicensable, worldwide, royalty-
bearing license to certain patent rights to develop, make, have made, use, sell, offer to sell, lease and import products and to
develop and perform processes which incorporate the licensed technology for the treatment or prevention of hearing loss.

The Company is required to use diligent efforts to develop and commercialize the licensed products and MEE has
control over the filing, prosecution, enforcement and defense of any licensed patent rights. We met one of our milestone
timeline obligations by dosing a first patient in a Phase II trial by December 31, 2020. We are still subject to a milestone
timeline obligation to dose a first patient in a Phase III trial by December 31, 2024.

Upon entering into the MEE License Agreement, the Company made a $20 license fee payment and is required to pay
certain annual license maintenance fees until the first commercial sale and a minimum annual royalty payment after the first
commercial sale.

The Company is also required to make milestone payments up to $350 on each product or process which incorporates

the licensed patent rights and pay a low single-digit royalty on products and processes that incorporate the licensed patent
rights.

The MEE License Agreement shall remain in effect until all issued patents and filed patent applications within the
licensed patent rights have expired or been abandoned, unless terminated earlier. The Company has the right to terminate the
MEE License Agreement at will by giving thirty (30) business days advance written notice to MEE. MEE has the right to
terminate the MEE License Agreement if the Company fails to make any payment due within thirty (30) business days after
MEE notifies the Company of such failure. MEE shall have the right to terminate if the Company fails to maintain the
required insurance. MEE shall also have the right to terminate the MEE License Agreement upon forty-five (45) business
days written notice if the Company becomes insolvent. MEE has the right to terminate for any other default not cured within
sixty (60) business days written notice. MEE also has the right to terminate if the Company or its affiliates challenge the
validity of the licensed patent rights.

Cambridge Enterprise Limited

In December 2019, we entered into an Exclusive Patent License Agreement ( the “Cambridge License”) with

Cambridge Enterprise Limited (the technology transfer arm of the University of Cambridge) (“Cambridge”) under which we
received an executive worldwide royalty-bearing license to certain patent rights to make, have made, sell, offer to sell and
import products, or the (the “Cambridge License Product”) which incorporate licensed technology for the treatment of
demyelinating diseases. We also have the right to grant nonexclusive licenses to other academic institutions for any
academic publication, research and teaching and clinical patient care.

F-27

The Company has agreed to use diligent and good faith efforts to develop and commercially exploit at least one
Cambridge Licensed Product. Upon entering into the Cambridge License, the Company made a $50 license fee payment.
The Company is obligated to pay an annual license fee of $50. The Company is also obligated to make milestone payments
up to $10.5 million on each Cambridge License Product. In addition, the Company has agreed to pay a low single-digit
royalty on products that incorporate the licensed patent rights, subject to offset in certain circumstances.

The Cambridge License continues in effect on a country-by-country basis until the expiration or revocation, without

right of further appeal, of all licensed issued patents and filed patent applications, unless terminated earlier. We have the
right to terminate for any reason upon 90 days’ prior to written notice. Each party has the right to terminate immediately if
the other party ceases to carry on its business. Either party may also terminate the Cambridge License for material breach if
such breach remains uncured for 30 days. Cambridge may also terminate the Cambridge License if we fail to diligently
develop and commercially exploit at least one Cambridge Licensed Product or we or our affiliates or sub-licenses commence
any action against Cambridge to declare or render any claim of the licensed patent rights invalid, unpatentable,
unenforceable, or not infringed.

Department of Defense

In June 2018, the Company received a grant (the Grant) from the Department of Defense (DoD) under which the
Company is receiving funding to further the Company’s research and development of a therapeutic drug to treat hearing loss.
The Company is receiving funding of $1,596 over two years from the date of the Grant. The Company has determined that
the DoD is not considered a customer under ASC 606, therefore funding received from the DoD under the Grant is recorded
as a reduction of research and development expenses. The Company has recorded $323 and $845 as a reduction in research
and development expenses for the years ended December 31, 2020 and 2019, respectively.

15. Collaboration agreement

In July 2019, the Company entered into a License and Collaboration Agreement with Astellas (the Astellas
Agreement), under which the Company granted Astellas an exclusive, royalty-bearing, sub-licensable, nontransferable
license to certain patent rights to research, develop, manufacture, have manufactured, use, seek and secure regulatory
approval for, commercialize, offer for sale, sell, have sold and import, and otherwise exploit licensed products containing
both a GSK-3 inhibitor and an HDAC inhibitor, (the Astellas Licensed Products), including the product candidate FX-322,
outside of the United States. The Company also granted Astellas a right of first negotiation and a right of last refusal if it
entered into any negotiation or agreement of any kind (other than an acquisition of all of the stock or assets of the Company)
with any third party under which such third party would obtain the right to develop, manufacture, or commercialize Astellas
Licensed Products in the United States.

The Company has agreed to conduct Phase 2a clinical studies in the United States. Upon the completion thereof, the
Company and Astellas have agreed to jointly develop the Astellas Licensed Products, including carrying out joint studies.
Each party has agreed to use commercially reasonable efforts to carry out development activities assigned to it under an
agreed-upon development plan. Astellas has agreed to use commercially reasonable efforts to obtain regulatory approval for
at least one Astellas Licensed Product in sensorineural hearing loss and in age-related hearing loss, in each case, in one major
Asian country and one major European country. The Company has agreed to use commercially reasonable efforts to obtain
regulatory approval for at least one Astellas Licensed Product in the United States. Astellas has the sole right to
commercialize the Astellas Licensed Products outside of the United States, and the Company has the sole right to
commercialize the Astellas Licensed Products in the United States. Astellas has agreed to use commercially reasonable
efforts to commercialize Astellas Licensed Products in a major Asian country and a major European country following
receipt of regulatory approval in such countries.

The collaboration is governed by a joint steering committee (“JSC”) established under the Astellas Agreement and

shall be comprised of three representatives each from the Company and Astellas. The JSC shall oversee and coordinate the
overall conduct of the development, manufacture and commercialization of the Astellas Licensed Products. All decisions of
JSC shall be taken through a unanimous vote with each party’s representatives collectively having one vote. Both the parties
shall be responsible for carrying out the development and manufacturing activities in their defined territory in accordance
with the plan as reviewed and approved in the JSC.

As consideration for the licensed rights under the Astellas Agreement, Astellas paid the Company an upfront payment

of $80.0 million in July 2019 and has agreed to pay potential development milestone payments up to $230.0 million and
commercialization milestones of up to $315.0 million. Specifically, the Company would receive development milestone

F-28

payments of $65.0 million and $25.0 million upon the first dosing of a patient in a Phase 2b clinical trial for SNHL in Europe
and Asia, respectively and $100.0 million and $40.0 million upon the first dosing of a patient in a Phase 3 clinical trial for
SNHL in Europe and Asia, respectively. If the Astellas Licensed Products are successfully commercialized, the Company
would be eligible for up to $315.0 million in potential commercial milestone payments and also tiered royalties at rates
ranging from low- to mid-teen percentages. The parties shall share equally, on a 50/50 basis, all out-of-pocket costs and joint
study costs for all the joint activities conducted pursuant to the development plans or the joint manufacturing plan.

The Astellas Agreement remains in effect until the expiration of all royalty obligations. Royalties are paid on a licensed

product-by-licensed product and country-by-country basis until the latest of (i) the expiration of the last valid claim in the
licensed patent rights with respect to such Astellas Licensed Product in such country or (ii) a set number of years from the
first commercial sale of such Astellas Licensed Product in such country. Astellas may terminate the Astellas Agreement at
will upon 60 days’ written notice. Each party has the right to terminate the Astellas Agreement due to the other party’s
material breach if such breach remains uncured for 90 days (or 45 days in the case of nonpayment) or if the other party
becomes bankrupt.

The Astellas Agreement is a collaborative agreement that is within the scope of ASC 808. The Company analyzed the

joint research and development activities to assess whether they fall within the scope of ASC 808, and will reassess this
throughout the life of the arrangement based on changes in the roles and responsibilities of the parties. Based on the terms of
the arrangement as outlined above, both parties are deemed to be active participants in the collaboration. Both parties are
performing research and development activities in their defined territory and will be performing joint clinical studies in
accordance with the development plan and the study protocol approved by the JSC. Additionally, Astellas and the Company
are exposed to significant risks and rewards dependent on the commercial success of any product candidates that may result
from the collaboration. As such, the collaboration arrangement is deemed to be within the scope of ASC 808.

The arrangement consists of two components; the license of IP and the research and development activities, including
committee participation, to support the co-development and research plan. Under the provisions of ASC 808, the Company
has determined that it will apply the guidance in ASC 606 to recognize the revenue related to the license since that
component of the arrangement is more reflective of a vendor-customer relationship. The Company determined that the
license and the related research and development services associated with the Phase 2a clinical study were not distinct from
one another, as the license has limited value to Astellas without the performance of the research and development activities
and the Phase 2a study is essential to the use of the license. As such, the Company determined that these activities should be
accounted for as a single combined performance obligation.

Revenue associated with this single performance obligation is being recognized as the research and development work
is performed, using an input method on the basis of research and development costs incurred to date relative to total research
and development costs expected to be incurred. The transfer of control occurs over this time period and, in management’s
judgment, is the best measure of progress towards satisfying the performance obligation. The Company has determined that
the period of performance of the research and development services began upon the signing of the Astellas Agreement and
will continue until the completion of the Phase 2a clinical trial of FX-322. The transaction price of $80.0 million has been
allocated to the single combined performance obligation and will be recognized over such period. Management has analyzed
the progress of the Phase 2a clinical trial and has estimated the completion date of such trial and the total costs it expects to
incur in performing the trial and is recognizing the $80.0 million upfront fee as revenue over the period from July 2019 until
the estimated completion date using the input method. The Company regularly assesses its estimates and to the extent that
facts and circumstances dictate, the Company revises its estimates of total cost or completion date and accounts for such
change on a prospective basis. The Company was required to pay MIT a royalty of $16.0 million on the $80.0 million of
sublicense revenues. The $16.0 million royalty was expensed in the third quarter of 2019.

The $80.0 million upfront payment received from Astellas in July 2019 was initially recorded as deferred revenue and
is being recognized as revenue according to the policy described above. In the year ended December 31, 2020, the Company
recognized $37.0 million of revenue under the Astellas Agreement. In the year ended December 31, 2019, the Company
recorded $28.9 million of revenue under the Astellas Agreement which included $16.0 million related to the royalty payment
to MIT and $12.9 million based upon the application of the input method to the remaining $64.0 million to be recognized
over the estimated period to completion of the Phase 2a clinical trial for FX-322.

The potential development and regulatory milestone payments are fully constrained until the Company can conclude
that achievement of the milestone is probable and that it is probable that recognition of revenue related to the milestone will
not result in a significant reversal in the amount of cumulative revenue recognized when the uncertainty associated with the
variable consideration is ultimately resolved and as such these have been excluded from the transaction price. As part of its

F-29

evaluation of the constraint, the Company considers numerous factors, including the fact that achievement of the milestones
is outside the control of the Company and contingent upon the future success of clinical trials, the licensee’s efforts, and the
receipt of regulatory approval. Any consideration related to sales-based milestones (including royalties) will be recognized
when the related sales occur as these amounts have been determined to relate predominantly to the license granted to Astellas
and therefore are recognized at the later of when the performance obligation is satisfied, or the related sales of licensed
products occur. The Company re-evaluates the transaction price, including its estimated variable consideration included in the
transaction price and all constrained amounts, at each reporting period and as uncertain events are resolved or other changes
in circumstances occur, and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are
recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

The Astellas Agreement contains joint research and development activities that are not within the scope of ASC 606.
The Company will recognize research and development expense related to the joint study costs for all the joint activities in
future periods and reimbursements received from Astellas will be recognized as an offset to research and development
expense on the consolidated statement of operations during the development period. In the years ended December 31, 2020
and 2019, the Company invoiced Astellas $1,046 and $186 for joint costs, respectively.

16. Commitments and contingencies

Operating leases

In 2016, the Company and a related third party (see Note 18) entered into a five-year operating lease for the

Company’s primary office and laboratory space in Woburn, Massachusetts. The lease was extended in November 2019 and
expires in February 2025. Additionally, the Company amended the lease in November 2019 to add additional laboratory and
office space. The commencement date of the additional space occurred in February 2020 and expires in February 2025. The
lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company also
leases a laboratory facility in Connecticut under an operating lease which expires in 2021.

On December 11, 2020, the Company entered into an Agreement for Termination of Lease and Voluntary Surrender of

Premises (the “Lease Termination Agreement”) with ARE-MA Region No. 20, LLC (the “Landlord”). The Lease
Termination Agreement provides that the Lease Agreement, dated as of August 14, 2016, by and between the Company and
Landlord (as the same may have been amended, the “Lease”) will terminate on March 31, 2021, unless the Company elects to
extend the term of the Lease. The Company exercised the option to extend the lease until May 31, 2021.

As consideration for the Landlord’s agreement to enter into the Lease Termination Agreement and accelerate the

expiration date of the term of the Lease, the Company has agreed to pay to Landlord a fee of approximately $0.2 million.

On January 7, 2020 the Company entered into an indenture of lease (the “Lexington Lease”) with HCP/KING 75

Hayden LLC, for the lease of approximately 61,307 square feet of rentable area in Lexington, Massachusetts or (the
“Lexington Premises”). The Lexington Lease commenced on December 11, 2020, (the “Commencement Date”). The
Company expects to use the Lexington Premises as its new principal executive offices and as a laboratory for research and
development, and other related uses. The term of the Lexington Lease, (the “ Initial Term”), is ten years from the rent
commencement date (which is five months following the Commencement Date) and the Initial Term is expected to end on
May 31, 2031. The Company also has the option to extend the Initial Term for two additional terms of five years each.

As of December 31, 2020, the Company has $30,551 of operating lease ROU assets, and $397 and $30,597 of current
and non-current lease liabilities, respectively, recorded on the consolidated balance sheets. For the year ended December 31,
2020 the Company recorded $470 of operating lease cost, $510 of variable lease cost, and $106 of short-term lease cost. The
lease expense for the years ended December 31, 2020 and 2019 are $835 and $269, respectively. Cash paid for amounts
included in the measurement of lease liabilities for year ended December 31, 2020 is $484.

Contract commitments

The Company has contracted with a research institution to provide research for a therapeutic drug to treat multiple
sclerosis. In September 2020, the Company extended the term of this contract through December 2021. As consideration for
this extension, the Company committed to total payments of $0.6 million through December 2021.

The Company enters into contracts in the normal course of business with CROs, CMOs, universities, and other third

parties for preclinical research studies, clinical trials and testing and manufacturing services. These contracts generally do not
contain minimum purchase commitments and are cancelable by us upon prior written notice although, purchase orders for
clinical materials are generally non-cancelable. Payments due upon cancellation consist only of payments for services
provided or expenses incurred, including non-cancelable obligations of our service providers, up to the date of cancellation or
upon the completion of a manufacturing run.

Guarantees

The Company has identified the guarantees described below as disclosable, in accordance with ASC 460, Guarantees.

As permitted under Delaware law, the Company indemnifies its officers and directors for certain events or occurrences
while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of
future payments the Company could be required to make is unlimited; however, the Company has directors’ and officers’
insurance coverage that should limit its exposure and enable it to recover a portion of any future amounts paid.

The Company is a party to a number of agreements entered into in the ordinary course of business that contain typical

provisions that obligate the Company to indemnify the other parties to such agreements upon the occurrence of certain
events. Such indemnification obligations are usually in effect from the date of execution of the applicable agreement for a
period equal to the applicable statute of limitations. The aggregate maximum potential future liability of the Company under
such indemnification provisions is uncertain.

F-31

The Company leases office space in Woburn, Massachusetts under a five-year non-cancelable operating lease, and has

entered into a facility lease in Lexington, Massachusetts. The Company has standard indemnification arrangements under
these leases that require it to indemnify the landlord against all costs, expenses, fines, suits, claims, demands, liabilities, and
actions directly resulting from any breach, violation, or nonperformance of any covenant or condition of the lease.

As of December 31, 2020 and 2019, the Company had not experienced any losses related to these indemnification

obligations, and no material claims with respect thereto were outstanding. The Company does not expect significant claims
related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible,
and no related reserves have been established.

17. Employee benefit plan

Employees of the Company are eligible to participate in the Company’s 401(k) retirement plan (the “401(k) Plan”).
Participants may contribute up to 90% of their annual compensation to the 401(k) Plan, subject to statutory limitations. Under
the 401(k) Plan Safe Harbor Match, the Company matches 100% of the first 5% of employee contributions and vests 100% at
time of match. For the years ended December 31, 2020 and 2019, the Company made matching contributions of $0.4 million
and $0.2 million, respectively.

18. Related party transactions

The Company’s lease for its Woburn, Massachusetts facility, see Note 16, is with an entity affiliated with one of the

Company’s directors and shareholders.

As disclosed in Note 14, the Company entered into the MIT License Agreement in December 2016. The patents in-

licensed by the Company from MIT pursuant to the MIT License Agreement claim inventions created by, among others, Dr.
Langer, one of the Company’s directors. Accordingly, Dr. Langer has received $1.98 million and $0.01 million from MIT
under the MIT Policy during the years ended December 31, 2020 and 2019, respectively.

19. Subsequent events

The Company has evaluated subsequent events for recognition, remeasurement and disclosure purposes through March

29, 2021, the date which the consolidated financial statements were available to be issued. The identified subsequent events
are as follows;

On February 18, 2021, the Company completed the liquidation and dissolution of Frequency Therapeutics Japan KK,

the Company’s Japanese subsidiary.

On March 23, 2021, the Company announced topline, day-90 data from its FX-322 Phase 2a study. The interim results

show that four weekly injections in subjects with mild to moderately severe sensorineural hearing loss did not demonstrate
improvements in hearing measures versus placebo. No treatment-related serious adverse events were observed in the study.

The Company also announced new preliminary data from a parallel study demonstrating hearing improvement from a

single injection of FX-322. The single dose showed efficacy that was clinically meaningful and statistically significant
compared to the untreated ear, had a favorable safety profile and was well tolerated.
