The following discussion and analysis of our financial condition and results of
operations should be read in conjunction with our consolidated financial
statements and the related notes to those statements included elsewhere in this
Annual Report on Form 10-K. In addition to historical financial information, the
following discussion and analysis contains forward-looking statements that
involve risks, uncertainties and assumptions. Some of the numbers included
herein have been rounded for the convenience of presentation. Our actual results
may differ materially from those anticipated in these forward-looking statements
as a result of many factors, including those discussed under Item 1A, Risk
factors, in this Annual Report on Form 10-K.

Overview



We are a biopharmaceutical company focused on transforming the treatment of
cancer and other diseases in collaboration with our partners by developing novel
therapeutic candidates engineered to harness the body's natural regulation of
protein levels to target and destroy disease-causing proteins. We leverage our
proprietary technology platform, TORPEDO (Target ORiented ProtEin Degrader
Optimizer), to synthesize a new class of small molecule medicines that
selectively and efficiently destroy disease-causing proteins. We are using our
TORPEDO platform to build a robust pipeline of orally administered protein
degradation drug candidates, with an initial focus on oncology indications. Our
approach to medicine harnesses the innate machinery of the cell to attack
disease and potentially bring deep and durable responses to patients.

Our most advanced product candidate, CFT7455, is an orally bioavailable degrader
of a protein target called IKZF1/3, for multiple myeloma, or MM, and non-Hodgkin
lymphomas, or NHLs, including peripheral T-cell lymphoma, or PTCL, and mantle
cell lymphoma, or MCL. We submitted an investigational new drug application, or
IND, for this product candidate to the U.S. Food and Drug Administration, or the
FDA, in December 2020 and received clearance from the FDA in January 2021; we
expect to begin a first-in-human Phase 1/2 clinical trial for this product
candidate in the first half of 2021.

We are also developing CFT8634, an orally bioavailable degrader of a protein
target called BRD9, for synovial sarcoma and SMARCB1-delete solid tumors, and we
expect to submit an IND for this product candidate to the FDA in the second half
of 2021 and begin a first-in-human Phase 1/2 clinical trial for this product
candidate in 2022.

In addition to our lead product candidates, we are also developing degraders
specifically targeting V600E mutant BRAF to treat melanoma, non-small cell lung
cancer, colorectal cancer and other solid malignancies that harbor this
mutation, as well as degraders targeting RET to treat lung cancer, sporadic
medullary thyroid cancers and other solid malignancies that harbor oncogenic RET
lesions. We expect to have product candidates from our two other lead programs,
BRAF V600E and RET, in the clinic by the end of 2022.

Financial Operations Overview

General



We commenced operations in October 2015, and our operations to date have been
limited to organizing and staffing our company, business planning, raising
capital, establishing development collaborations with Roche, Biogen and Calico,
conducting discovery and research activities, filing patent applications,
identifying potential product candidates, undertaking preclinical studies and
establishing arrangements with third parties for the manufacture of initial
quantities of our product candidates. To date, we have not generated any revenue
from product sales and have financed our operations primarily through sales of
our equity interests and proceeds from our collaborations. Through December 31,
2020, we have raised approximately $224.0 million in gross proceeds from the
sale of our preferred stock, $209.8 million in gross proceeds from our initial
public offering, and have received an aggregate of $167.5 million in payments
from collaboration partners.

Our ability to generate revenue from product sales sufficient to achieve
profitability will depend heavily on the successful development and eventual
commercialization of one or more of our product candidates. Since inception, we
have incurred significant operating losses. We expect to continue to incur
significant expenses and increasing operating losses for at least the next
several years. Our net losses were $66.3 million and $34.1 million for the years
ended December 31, 2020 and 2019, respectively. As of December 31, 2020, we had
an accumulated deficit of $183.8 million.

Our total operating expenses were $93.6 million and $56.8 million for the years
ended December 31, 2020 and 2019, respectively. We anticipate that our expenses
will increase substantially in the future due to costs including those
associated with the following:

• our preclinical activities for our lead product candidates and the

advancement of these candidates into first-in-human Phase 1/2 clinical trial

in the United States, which we expect to initiate in the first half of 2021


      for CFT755 and in 2022 for CFT8634;


  • development activities associated with our other product candidates;


                                       86

--------------------------------------------------------------------------------

• research activities in oncology, neurological and other disease areas to

expand our pipeline;

• hiring additional personnel in research, clinical trials, quality and other


      functional areas;


   •  increased activities by our CMOs to supply us with product for our
      preclinical studies and clinical trials;


  • the management of our intellectual property portfolio; and


  • operating as a public company.


In addition, our net losses and cash flows may fluctuate significantly from
period to period depending on, among other things, variations in the level of
our expenses and the execution of any additional collaboration, licensing or
similar arrangements, and the timing of payments we may make or receive under
these types of arrangements.

As a result of these anticipated expenditures, we will need substantial
additional funding to support our operating activities as we advance our product
candidates through clinical development, seek regulatory approval and prepare
for and, if any of our product candidates are approved, proceed to
commercialization. Until such time as we can generate significant revenue from
product sales, if ever, we expect to finance our operating activities through a
combination of equity offerings, debt offerings, reimbursements and potential
milestones earned under our existing collaboration agreements and potential
license and development agreements with third parties, including but not limited
to our existing collaboration partners. Adequate funding may not be available to
us on acceptable terms, or at all.

COVID-19



The impact of the COVID-19 coronavirus outbreak on our financial performance
will depend on future developments, including the duration and spread of the
outbreak and related governmental advisories and restrictions. There are
multiple causes of these delays, including laboratory closures, reluctance of
patients to enroll or continue in trials for fear of exposure to COVID-19, local
and regional shelter-in-place and work from home orders and regulations that
discourage, hamper or prohibit patient visits, healthcare providers and health
systems shifting away from clinical trials toward the acute care of COVID-19
patients and the FDA and other regulators making product candidates for the
treatment of COVID-19 a priority over product candidates unrelated to the
pandemic.

In terms of the impact on our operations, we have seen increased risk of delays
in production of components used to manufacture our lead degrader candidates due
to previous delays at one of our China-based manufacturers, periodic shipping
delays and resourcing constraints and, therefore, somewhat higher costs to
compete our discovery activities on one or more of our lead projects, and one of
our contract research organizations, or CROs, in India was forced to temporarily
shut down due to local lockdown orders. In addition, we temporarily closed the
office and laboratory spaces at our corporate headquarters in Watertown,
Massachusetts, and we transitioned our employees to work from home. We are
working closely with our CROs, manufacturers, investigators and preclinical and
clinical trial sites to assess the full impact of the COVID-19 pandemic on the
timelines and expected costs for each of our programs. While the ongoing impact
of the pandemic is uncertain, we believe our CRO redundancies in China, India
and Boston and the transition of the majority of our employees to remote work
arrangements have helped mitigate the impact of these types of disruptions on
our business.

Given the breadth and duration of the global COVID-19 pandemic, it is possible
that our directors or employees could, at any time, have been or become infected
with this novel coronavirus, especially since methods and availability of
testing are continuing to evolve. To date, we have not experienced or had to
impose any material shutdowns as a result of positive test results for this
novel coronavirus.

We note the high level of difficulty in projecting the effects of COVID-19 on
our programs and our company, given the rapid and dramatic evolution in the
course and impact of the pandemic and the societal and governmental response to
it.

Financial Operations Overview

Revenues

As previously discussed, to date, we have not generated any revenue from product
sales and do not expect to generate any revenue from the sale of products for
the foreseeable future. Our revenues to date have been generated through
research collaboration and license agreements. We recognize revenue over our
expected performance period under each agreement. We expect that our revenue for
the next several years will be derived primarily from our current collaboration
agreements and any additional collaborations that we may enter into in the
future. To date, we have not received any royalties under any of our existing
collaboration agreements.

Roche Collaboration and License Agreement



In March 2016, we entered into the Original Roche Agreement with Roche, whereby
Roche provided us with a non-refundable upfront payment of $15.0 million, which
was creditable against our target initiation fees of either $1.0 million or

                                       87

--------------------------------------------------------------------------------
$4.0 million, depending on the compound selected. Pursuant to the terms of the
Original Roche Agreement, we collaborated on research activities to develop
novel treatments in the field of targeted protein degradation using our degrader
technology. We initially developed therapeutics that utilize degrader technology
for up to ten target proteins. On a target-by-target basis, after successful
completion of a defined preclinical development phase, Roche had an exclusive
option to pursue a license from us for further clinical development and
commercialization.

On December 22, 2018, we amended and restated the Original Roche Agreement, or
the Roche Agreement. Under the Roche Agreement, we have a more active role in
the manufacturing and commercialization of the targets included in the
collaboration, whereby if we opt into certain co-development and co-detailing
rights, the parties will split future development costs in return for our having
rights to a larger share of future earnings from commercialization of the
relevant target. The target structure was revised to six potential targets,
three of which had been nominated as of the execution of the Roche Agreement and
represent continuations of the initial preclinical research and development
efforts begun under the Original Roche Agreement, and three additional targets
that were not nominated as of the date of execution of the Roche Agreement. At
the time of entry into the Roche Agreement, Roche maintained its option rights
to license and commercialize these six targets.

Under the Roche Agreement, we received additional upfront consideration of
$40.0 million from Roche. Roche will make annual research plan payments of
$1.0 million for each active research plan. Finally, adjustments were made to
the option exercise fees, whereby targets that have progressed through GLP
toxicology studies at the time of exercise now have option exercise fees of
$7.0 million to $12.0 million and those progressed through Phase 1 trials have
option exercise fees of $20.0 million.

For certain targets, Roche is required to pay us fees of $2.0 million and
$3.0 million upon the identification of a lead series and the commencement of
GLP toxicology studies, respectively. For each target option exercised by Roche,
we are eligible to receive up to $275 million in research, development and
commercial milestone payments per target. Roche is also required to pay us up to
$150 million per target in one-time sales-based payments if the target achieves
certain levels of net sales. Roche is also required to pay us royalties, at
percentages from the mid-single digits to the low double-digits, on a licensed
product-by licensed product basis, on worldwide net product sales.

In November 2020, we signed a further amendment to the Roche Agreement that
provides a mechanism through which we and Roche can mutually agree to terminate
the Roche Agreement on a target-by-target basis by the entry into a mutual
target termination agreement. Upon a termination of this nature, the Roche
Agreement, as amended, provides that all rights in know-how and intellectual
property in support of products that use inhibition as their mode of action,
referred to as the Roche Field, will revert to Roche and all rights in respect
of know-how and intellectual property in support of products that use
degradation as their mode of action, referred to as the C4T Field, will revert
to us. Further, this amendment states that, following the entry into a mutual
target termination agreement, Roche will have rights in and responsibility for
any know-how and intellectual property generated as a result of the
collaboration that fits within the Roche Field and we will have rights in and
responsibility for any know-how and intellectual property generated as a result
of the collaboration that fits within the C4T Field. In support of this
allocation of rights, under the amendment, Roche provided us, and we provided
Roche, with a perpetual, irrevocable, fully paid up, exclusive (even as to party
granting the license), sublicensable (including in multiple tiers) license to
the patents that are allocated to a party under the mutual target termination
agreement and a perpetual, irrevocable fully paid up, non-exclusive,
sublicensable (including in multiple tiers) license to the know-how that is
allocable to a party under the mutual termination agreement. Finally, through
the entry into this amendment, we and Roche mutually agreed to terminate the
Roche Agreement as to the target EGFR. As a result, Roche is now free to pursue
the target EGFR in the Roche Field and we are free to pursue the target EGFR in
the C4T Field and all rights in and responsibility for know-how and intellectual
property related to EGFR in the Roche Field reverted to the Roche parties and
all rights in and responsibility for know-how and intellectual property related
to EGFR in the C4T Field reverted to us, with Roche assigning the relevant
patents in the C4T Field to us.

Biogen Collaboration Research and License Agreement



On December 28, 2018, we entered into the Biogen Agreement, with Biogen, whereby
we agreed to collaborate on research and development efforts for up to five
targets to discover and develop potential new treatments for neurological
conditions, such as Alzheimer's disease and Parkinson's disease. The Biogen
Agreement also has an option for Biogen to nominate additional targets and
extend the Biogen Agreement. In February 2020, we entered into an amendment to
the Biogen Agreement that provided further clarity around Biogen's ownership of
target binding moieties, which are portions of molecules, and any related
intellectual property that are directed at or bind to collaboration targets.
This amendment further provides that Biogen licenses to us rights to use these
Biogen target binding moieties and any related intellectual property as needed
in order to conduct the research and development activities contemplated under
the Biogen Agreement.

We granted Biogen a non-exclusive research license under our intellectual property to perform research activities, select and optimize degraders and develop products including the degraders, as well as a commercial license to manufacture and



                                       88

--------------------------------------------------------------------------------
commercialize the targets once the initial research and development work is
complete. The research under the Biogen Agreement will take place over a
54-month research term with Biogen having an option to extend the Biogen
Agreement for up to four additional years. If Biogen elects to extend the term
of the Biogen Agreement, Biogen would be required to make an additional payment
of $62.5 million and would be entitled to nominate up to five additional
targets.

The Biogen Agreement provides for three initial targets, with Biogen having the
right to initiate up to an additional two targets and to control all
post-discovery activities. Biogen paid us a nonrefundable upfront payment of
$45.0 million for access to our technology and research services through the
discovery research phase. The nonrefundable upfront cash payment of
$45.0 million is not creditable against any of the target development milestone
fees.

Following the achievement of development candidate criteria, prior to any
IND-enabling study, for any target, Biogen will bear all costs and expenses of
and will have sole discretion and decision-making authority with respect to the
performance of further activities with respect to any degrader under development
under the Biogen Agreement and all products that incorporate that degrader.
Biogen is also required to pay us up to $35.0 million per target in development
milestones and $26.0 million per target in one-time sales-based payments for the
first product to achieve certain levels of net sales. In addition, Biogen is
required to pay us royalties on a licensed product-by-licensed product basis, on
worldwide net product sales, at percentages in the mid-single digits. All
milestone and sales-based payments are made after we have met the defined
criteria in the joint research plan for that target, at which time Biogen will
have control of the targets for commercialization; the receipt of these payments
is contingent on the further development of the targets to commercialization by
Biogen, without any additional research and development efforts from us.

Biogen also has the option to fund additional discovery activities, whereby we
will perform discovery-type research at Biogen's election to develop other
potential targets that may be used as replacement targets for the initially
nominated targets or two additional targets under the Biogen Agreement. Revenues
earned under this option, if initiated, will be recognized as services are
performed and are not included in the transaction price at the outset of the
arrangement. These research activities will be reimbursed on a full-time
equivalent, or FTE, basis at specified market rates. These additional discovery
activities can be purchased up to a maximum amount by Biogen on an à la carte
basis at an amount consistent with standalone selling price. If Biogen were to
exercise these options, we would recognize revenue as those options are
exercised.

Calico License Agreement



In March 2017, we entered into the Calico Agreement, with Calico whereby we
agreed to collaborate to develop and commercialize a set number of targets for
small molecule protein degraders for diseases of aging, including cancer, for a
five-year period ending in March 2022, or the research term.

We provided Calico with a non-exclusive research license under our intellectual
property to perform research activities and select and optimize degraders and
develop products including the degraders. We also granted Calico a commercial
license for any licensed products resulting from the development candidates
supplied by us. We are required to perform research and development activities
for the nominated targets over the research term, with the intent to provide a
development candidate for each target to Calico once the agreed-upon research is
complete.

Calico is obligated to reimburse our research and development activities for
each target at specified levels through the identification of a development
candidate, after which Calico shall assume full responsibility for candidate
development.

After the initiation of each target, the Calico Agreement does not contain any
options for Calico to license the individual targets; once we complete the
initial research and development activities required, Calico controls and
directs the targets with no additional work required to be performed by us.
There is no exercise price or incremental fee payable to us to progress the
research further, though Calico is required to pay an initiation fee with the
commencement of each research plan. Once Calico nominates a target and pays the
applicable target initiation fee, we will commence research and development
activities for that target. The Calico Agreement provides for up to five initial
targets. Research activities performed are reimbursed at specified levels for
the five-year term of the Calico Agreement.

Under this agreement, Calico paid us a nonrefundable upfront amount of
$5.0 million and certain annual payments of $5.0 million through December 31,
2020. Upon our completion of the required discovery research and development
services on any target, Calico is entitled to pursue commercial development of
that target. For each target, we are eligible to receive potential research,
development and commercial milestone payments aggregating up to $132.0 million.
Calico is also required to pay one-time sales-based payments aggregating up to
$65.0 million for the first product to achieve certain levels of net sales. In
addition, Calico is required to pay us royalties, on a licensed
product-by-licensed product basis, on worldwide net product sales, at
percentages in the mid-single digits. All milestone and sales-based payments are
made after we have met the defined criteria in the joint research plan for that
target, at which time Calico will have control of the targets for
commercialization; the receipt of these payments by us is contingent on the
further development of the targets to commercialization by Calico, without any
additional research and development efforts required by us.

--------------------------------------------------------------------------------

Research and Development Expenses



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

• 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 and other third parties that conduct research and

preclinical activities on our behalf as well as third parties that

manufacture our product candidates for use in our preclinical and potential

future clinical trials;

• costs of outside consultants, including their fees, unit-based compensation

and related travel expenses;

• the costs of laboratory supplies and acquiring materials for preclinical

studies and clinical trials;

• facility-related expenses, which include direct depreciation costs of

equipment and allocated expenses for rent and maintenance of facilities and


      other operating costs; and


  • third-party licensing fees.


We expense research and development costs as incurred. Costs for external
development activities are recognized based on an evaluation of the progress to
completion of specific tasks using information provided to us by our vendors.
Payments for these activities are based on the terms of the individual
agreements, which may differ from the pattern of costs incurred, and are
reflected in our consolidated financial statements as prepaid or accrued
research and development expenses. Nonrefundable advance payments for goods or
services to be received in the future for use in research and development
activities are recorded as prepaid expenses and expensed as the related goods
are delivered or the services are performed.

We expect that our research and development expenses will increase substantially in connection with our planned preclinical and clinical development activities.

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, legal, 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 include direct depreciation costs and allocated
expenses for rent and maintenance of facilities and other operating costs.

We expect that our general and administrative expenses will increase in the future to support our growing operations, including additional personnel to support our operations as a publicly traded company. We also expect to incur increased expenses associated with being a public company, including higher costs of accounting, audit, legal, regulatory and tax-related services associated with maintaining compliance with Nasdaq and SEC requirements, director and officer insurance costs and investor and public relations costs.

Other (Expense) Income



Other income (expense) primarily consists of change in fair value of warrant
liability. Prior to the closing of the IPO, a warrant issued in connection with
our long-term debt was classified as a liability with changes in fair value of
the liability recorded within other (expense) income. Upon closing of the IPO,
the warrant was determined to be an equity instrument. Refer to Note 9,
Long-term Debt and Warrant Liability, accompanying our consolidated financial
statements for additional discussion.

In addition to changes in the fair value of our warrant liability, other income
(expense) also includes interest expense and amortization of the long-term debt,
which is discussed in greater detail in Note 9, Long-term Debt and Warrant
Liability, accompanying our consolidated financial statements.

Finally, other income (expense) also includes interest income earned on our cash, cash equivalents, and marketable securities and accretion of discount on marketable securities.

Results of Operations

Comparison of years ended December 31, 2020, 2019, and 2018

Revenue

Revenue from our collaboration and license agreements consisted of the following for the years ended December 31, 2020, 2019, and 2018 (in thousands):



                                              Years Ended December 31,
                                           2020         2019         2018
              Roche Agreement            $  9,051     $  6,409     $  9,112
              Biogen License Agreement      9,913        2,432            -
              Calico License Agreement     14,231       12,540       10,252
              Total                      $ 33,195     $ 21,381     $ 19,364

The $11.8 million increase in revenue in the year ended December 31, 2020 as compared to the year ended December 31, 2019 is primarily driven by:

$2.6 million increase in revenue recognized under the Roche Agreement due to

increased effort made on three targets;

$7.5 million increase in revenue recognized under the Biogen Agreement due

to the consideration to be recognized as revenue increasing by the $4.0

million milestone earned in June 2020 and as a result of increased effort

made on the initial three targets nominated and an increase in sandbox

related revenue of $2.3 million; and

$1.7 million increase in revenue recognized under the Calico Agreement

primarily related to additional FTE reimbursement received in 2020 resulting

from increased effort made on Calico targets.

The $2.0 million increase in the year ended December 31, 2019 as compared to the year ended December 31, 2018 primarily stems from:

$2.4 million of revenue recognized under the Biogen Agreement for

collaboration efforts conducted under Biogen agreement, which was executed

in December 2018, including sandbox revenue of $0.5 million;

• A $2.3 million increase in revenue recognized under the Calico Agreement

due to additional collaboration efforts conducted in 2019;

• offset by a $2.7 million decrease in the revenue recognized under the Roche

Agreement executed in December 2018. The Roche Agreement was considered a


       modification of the Original Roche Agreement and upon its execution we
       identified additional performance obligations that have yet to be
       satisfied, resulting in additional revenue being deferred pending the
       satisfaction of those performance obligations.

Research and Development Expenses

The following table summarizes our research and development expenses for the years ended December 31, 2020, 2019, and 2018 (in thousands):



                                                    Years Ended December 31,
                                                 2020         2019         2018
        Preclinical and development expenses   $ 42,025     $ 22,202     $  8,504
        Personnel expenses                       20,135       14,085        9,734
        Facilities and supplies                   9,496        8,933        7,885
        Professional fees                         4,816        1,573        1,167
        Intellectual property                     1,599          798          866
        Other expenses                              369          468          436
        Total                                  $ 78,440     $ 48,059     $ 28,592

The $30.4 million increase in research and development expense in the year ended December 31, 2020 from the year ended December 31, 2019 is primarily driven by:

• a $19.8 million increase in preclinical and development costs, consisting of

$11.9 million increase in external FTEs used in preclinical development of


      our various programs, and $9.1 million of costs related to the IND
      submission for our CFT7455 and CFT8634 programs;


                                       91

--------------------------------------------------------------------------------

• a $6.1 million increase in personnel expenses, representing salary and

benefit costs, including a $0.6 million increase in stock-based compensation

expense, primarily due to the buildout of our clinical development team; and

• a $3.2 million increase in professional fees, which primarily consists of

consulting costs for our development activities.

The $19.5 million increase in research and development expense for the year ended December 31, 2019 from the year ended December 31, 2018 was primarily due to:

• a $13.7 million increase in preclinical and development costs, driven

primarily by an $8.3 million increase in external FTE resources used in

preclinical development of our various programs, and a $5.7 million increase

in external preclinical studies for our product candidates; and

• a $4.4 million increase in personnel expenses, related to personnel costs

attributable to an increase in headcount.

General and Administrative Expenses

The following table summarizes our general and administrative expenses for the years ended December 31, 2020, 2019, and 2018 (in thousands):

The $6.4 million increase in general and administrative expense in the year ended December 31, 2020 as compared to the year ended December 31, 2019 is primarily driven by:

• a $2.3 million increase in personnel expenses, representing salary and

benefit costs, including a $1.2 million increase in stock-based compensation

expenses, resulting from additional G&A personnel hired during the year; and

• a $4.1 increase in professional fees, which primarily includes a $2.3

million increase in consultant fees, and higher legal and audit and

insurance expenses, resulting from our transition to a public company.

The $1.6 million increase in general and administrative expense in the year ended December 31, 2019 from the year ended December 31, 2018 was primarily due to:

• a $1.6 million increase in personnel expenses resulting from $0.8 million

increase in stock-based compensation expense due to increase in personnel

expenses and a $0.8 million increase in other personnel-related expenses.




Other (Expenses) Income

The following table summarizes our other (expense) income for the years ended December 31, 2020, 2019, and 2018 (in thousands):

The $8.7 million change in other (expenses) income for the years ending December 31, 2020 as compared to the year ending December 31, 2019 was driven by the following:

• a $5.7 million charge due to the increase in fair value of warrant liability

associated with our long-term debt, which, prior to our IPO, was revalued at

each reporting period

• a $1.2 million change resulting from interest expense and amortization of

the discount related to our long-term debt; and

• a $1.8 million change in interest and other income resulting from lower


      interest rates earned on our investments.

--------------------------------------------------------------------------------



The $1.5 million increase in interest and other income (expenses) for the years
ending December 31, 2019 as compared to the year ending December 31, 2018 was
primarily due to increased interest income resulting from a higher average cash
balance.

benefit related to an anticipated refund to be received for federal taxes under
the corporate provisions of the CARES Act.

For the year ended December 31, 2019, we recognized income tax expense of $0.8
million resulting from taxable income primarily caused by the Roche Agreement
and Biogen Agreement, both entered into in December 2018.

Liquidity and Capital Resources

Sources of Liquidity



Since our inception in 2015, we have incurred significant operating losses. We
expect to incur significant expenses and operating losses for the foreseeable
future as we advance the preclinical and, if successful, the clinical
development of our programs. We do not currently have any approved products and
have never generated any revenue from product sales. To date, we have financed
our operations primarily through the sale of preferred stock, our IPO, and
through payments from collaboration partners. Through December 31, 2020, we have
raised approximately $224.0 million in gross proceeds from the sale of preferred
stock, $209.8 million in gross proceeds from our IPO, and have received an
aggregate of $167.5 million in payments from collaboration partners. As of
December 31, 2020, we had cash, cash equivalents and marketable securities of
approximately $371.7 million.

In June 2020 and July 2020, we closed our Series B Financing with both existing
and new investors. As part of the Series B Financing, we issued 142,857,142
shares of redeemable convertible Series B preferred stock, or Series B Preferred
Stock, at a purchase price of $1.05 per share, for aggregate gross proceeds of
$150.0 million, or net proceeds of $145.5 million when taking into account
offering costs of $4.5 million. Upon completion of the IPO, every 8.4335 shares
of our preferred stock was automatically converted into one share of common
stock.

In addition, in June 2020, we secured a $20.0 million credit arrangement with
Perceptive Credit Holdings III, LP, or Perceptive Credit, an affiliate of one of
the Series B Financing investors, whereby we borrowed $12.5 million at closing,
bearing a variable interest rate of 11.25%, and have the opportunity to draw
down another $7.5 million subject to the satisfaction of certain milestones
relating to the filing of an IND for certain of our pipeline targets, which was
met with the filing of our IND for CFT7455 in December 2020. Our ability to draw
down on this second tranche expires on June 30, 2021. In connection with the
Credit Agreement, we issued Perceptive Credit a warrant to purchase 2,857,142
shares of Series B Preferred Stock exercisable for $1.05 per share. Upon
completion of the IPO, this warrant converted to a warrant to purchase 338,784
shares of our common stock for $8.86 per share. The loans extended under the
Credit Agreement will be repaid beginning in December 2022 in monthly
installments of interest plus principal equal to 2.0% of the initial principal
amount through June 2024. We paid a closing fee of $0.3 million related to the
loan and have the right to prepay the loan in its entirety prior to the maturity
date by paying the applicable prepayment fee. Per the terms of the Credit
Agreement, the prepayment fee is $5.0 million, less any interest paid as of the
prepayment date, which totaled $4.2 million as of December 31, 2020. If we do
not prepay the loan, the entire unpaid principal balance becomes due on the
maturity date, which is June 5, 2024. We are also subject to customary financial
covenants in the Credit Agreement that dictate accelerated repayment upon the
occurrence of certain events of default, none of which are expected to occur
based on our current liquidity.

In October 2020, we completed our IPO in which we issued and sold 11,040,000
shares of common stock, including 1,440,000 shares of our common stock sold
pursuant to the underwriters' full exercise of their option to purchase
additional shares, at a price to the public of $19.00. The proceeds from our
IPO, including the full exercise of the underwriter's overallotment option, were
approximately $191.2 million after deducting underwriting discounts and
commissions of $14.7 million and expenses of $3.9 million.

Operating Activities

Net cash used in operating activities for the year ended December 31, 2020 was driven primarily by:

• our net loss of $66.3 million;

• a $12.2 million change in deferred revenue due to the recognition of revenue


      under our collaboration agreements in 2020; and


  • a $3.3 million change in prepaid expenses and other current assets.

These were offset by:

• a $11.9 million of non-cash expense related to depreciation, stock

compensation expense, reduction in right-of-use asset, and change in fair


      value of warrant liability; and


  • a $2.6 million change in accrued expenses and other liabilities.

Net cash provided by operating activities for the year ended December 31, 2019 was driven primarily by:

• an $81.8 million decrease in accounts receivable related to the collection

of up-front payments from our collaboration partners received in 2019;

$8.0 million due to changes in operating assets and liabilities, including

increases in accounts payable and accrued expenses, stemming from increased

clinical and preclinical efforts to advance our product candidates in 2019;

and

$4.3 million of non-cash expenses related to stock-based compensation

expenses, depreciation expense, and reduction in right-of-use asset.

These were offset by:

• our net loss of $34.1 million and a $3.2 million; and

• a change in deferred revenue due to the recognition of revenue under our

collaboration agreements in 2019.

Net cash used in operating activities for the year ended December 31, 2018 primarily consist of:

• our net loss of $15.7 million; and

• a change of $84.9 million in accounts receivable, offset by a change of

$81.0 million in deferred revenue both changes driven by $85.0 million in

up-front payments due to us under the Roche Agreement and the Biogen

Agreement, both of which were recorded as accounts receivable and deferred

revenue as of December 31, 2018.

Investing Activities

The $190.5 million of net cash used in investing activities for the year ended December 31, 2020 was attributable to:

$189.9 million for the purchases of marketable securities, net of
       maturities; and


  • $0.7 million for the purchases of property and equipment.

The $1.6 million of net cash used in investing activities for the year ended December 31, 2019 was attributable to:

$1.3 million for the net purchases of property and equipment; and

$0.3 million for the purchases of marketable securities, net of maturities.

The $36.9 million of net cash provided by investing activities for the year ended December 31, 2018 was attributable to:

$39.6 million from maturities of marketable securities, net of purchases; and




                                       94

--------------------------------------------------------------------------------
$2.7 million for the purchases of property and equipment.

Financing Activities

The $348.9 million of net cash provided by financing activities for the year ended December 31, 2020 is primarily driven by:

$191.5 million of proceeds from our IPO, net of underwriting discount and

offering costs paid in 2020;

$145.5 million of proceeds from our Series B issuance, net of issuance

costs; and

$12.0 million of proceeds from issuance of long-term debt and warrant, net

of issuance costs.




The $0.2 million of net cash provided by financing activities for the year ended
December 31, 2019 was primarily attributable to net proceeds received from the
issuance of common stock in conjunction with the exercise of stock options.

The $2.0 million of net cash provided by financing activities for the year ended
December 31, 2018 was primarily attributable to net proceeds received from the
issuance of Series A redeemable convertible preferred stock in December 2018.

Funding Requirements



Since our inception, we have incurred significant operating losses. We expect to
continue to incur significant expenses and increasing operating losses for the
foreseeable future as we advance the preclinical and clinical development of our
product candidates. In addition, subsequent to our IPO, we expect to incur
additional costs associated with operating as a public company.

Specifically, we anticipate that our expenses will increase substantially in the future, if and as we:

• initiate planned first-in-human Phase 1/2 trials of our lead product


      candidates, CFT7455 and CFT8634;


   •  advance additional product candidates into preclinical and clinical
      development;


  • continue to invest in our proprietary TORPEDO platform;


  • expand, maintain and protect our intellectual property portfolio;


  • hire additional clinical, regulatory and scientific personnel;

• add operational, financial and management information systems and personnel

to support our ongoing research, product development, potential future


      commercialization efforts, operations as a public company and general and
      administrative roles;

• seek marketing approvals for any product candidates that successfully

complete clinical trials; and

• ultimately establish a sales, marketing and distribution infrastructure and

scale up external manufacturing capabilities to commercialize any products

for which we may obtain marketing approval.




Because of the numerous risks and uncertainties associated with development and
commercialization of our product candidates, we are unable to estimate the
amounts of increased capital and operating costs associated with our current and
anticipated preclinical and clinical development. Our future capital
requirements will depend on many factors, including:

• the progress, costs and results of our planned first-in-human Phase 1/2

trials for our lead product candidates and any future clinical development


      of those lead product candidates;


   •  the scope, progress, costs and results of preclinical and clinical

development for our other product candidates and development programs;

• the number and development requirements of other product candidates that we

pursue;

• the success of our collaborations with Roche, Biogen and Calico, including

whether or not we receive additional research support or milestone payments

from our collaboration partners upon the achievement of milestones;

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

• the costs and timing of preparing, filing and prosecuting patent

applications, maintaining and enforcing our intellectual property rights and


      defending any intellectual property-related claims;


   •  our willingness and ability to establish additional collaboration
      arrangements with other biotechnology or pharmaceutical companies on
      favorable terms, if at all, for the development or commercialization of
      current or additional future product candidates;


                                       95

--------------------------------------------------------------------------------

• the costs and timing of future commercialization activities, including


      product manufacturing, marketing, sales and distribution, for any of our
      product candidates for which we receive marketing approval; and


   •  the revenue, if any, received from commercial sales of our product
      candidates for which we receive marketing approval.


As a result of the anticipated expenditures described above, we will need to
obtain substantial additional financing to support our continuing operations and
pursue our long-term business plan. Until such time, if ever, as we can generate
substantial revenue from product sales, we expect to finance our cash needs
through a combination of equity offerings, debt offerings, collaborations,
strategic alliances and marketing, distribution or licensing arrangements.
Although we may receive potential future milestone and royalty payments under
our collaborations with Roche, Biogen and Calico, we do not have any committed
external source of funds, as of December 31, 2020, other than an additional
$7.5 million under our Credit Agreement, which we may elect to draw down at any
time prior to June 30, 2021. Adequate additional funds may not be available to
us on acceptable terms, or at all. If we are unable to raise capital when needed
or on attractive terms, we may be required to delay, limit, reduce or terminate
our research, product development or future commercialization efforts or grant
rights to develop and market product candidates that we would otherwise prefer
to develop and market ourselves.

To the extent that we raise additional capital through the sale of equity
securities, each investor's 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. Preferred equity financing, if
available, may involve agreements that include covenants limiting or restricting
our ability to take specific actions, such as making acquisitions or 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
have to relinquish valuable rights to our technologies, future revenue streams,
research programs or product candidates or grant licenses on terms that may not
be favorable to us.

Contractual Obligations

The following is a summary of our significant contractual obligations as of December 31, 2020 (in thousands):



                                                    Less than       1 to 3

(1) Represents future minimum lease payments under our operating leases for

office and lab space in Watertown, Massachusetts that expires in April 2028.




We enter into contracts in the normal course of business with third-party CROs
for clinical trials, preclinical studies, manufacturing and other services and
products for operating purposes. These contracts generally provide for
termination following a certain period after notice and therefore we believe
that our non-cancelable obligations under these agreements are not material and
they are not included in the table above. We have not included milestone or
royalty payments or other contractual payment obligations in the table above if
the timing and amount of such obligations are unknown or uncertain.

Critical Accounting Estimates



This management's discussion and analysis of financial condition and results of
operations is based on our consolidated financial statements, which have been
prepared in accordance with generally accepted accounting principles 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, revenues, 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 Note
2, Summary of significant accounting policies, to our consolidated financial
statements 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.

                                       96

--------------------------------------------------------------------------------

Revenues from Contracts



We account for our revenue in accordance with Accounting Standards Codification,
or ASC, 606, Revenue from Contracts with Customers, or ASC 606. Under ASC 606,
an entity recognizes revenue when its customer obtains control of promised goods
or services, in an amount that reflects the consideration that the entity
expects to receive in exchange for those goods or services. To determine revenue
recognition for arrangements that an entity determines are within the scope of
ASC 606, the entity performs the following five steps at inception of the
agreement or upon material modification of the agreement: (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 a performance obligation.

Identify the Contract

In determining whether a contract is within the scope of ASC 606, we consider the following criteria:

• The parties to the contract have approved the contract, whether written,


      orally, or in accordance with other customary business practices, and are
      committed to perform their respective obligations.

• The entity can identify each party's rights regarding the goods or services

to be transferred.

• The entity can identify the payment terms for the goods or services to be

transferred.

• The contract has commercial substance (that is, the risk, timing, or amount


      of the entity's future cash flows is expected to change because of the
      contract).


   •  It is probable that the entity will collect substantially all the
      consideration to which it will be entitled in exchange for the goods or
      services that will be transferred to the customer.


In determining whether the criteria above have been met, management confirms
that the agreement has been signed by both parties or approved in another
acceptable manner, reviews that the agreement identifies rights and obligations
of each party, both written and implied, determines whether the contract has
economic consequences for all parties, and whether we will be able to collect
substantially all the consideration that is due or will become due under the
contract. The determination of collectability requires the most judgement and,
in establishing collectability, management considers payment terms, ability to
stop transferring goods or service to customer in the event of nonpayment,
experience with the customer, class of customer, and expectations about the
customer's financial stability, as well as other factors.

Identify the Performance Obligations



Once a contract is determined to be within the scope of ASC 606, we identify all
promised goods and services in the contract, which includes those that are
explicitly stated within the contract and those that are implied. Once all
promised goods and services within the contract are identified, we evaluate
whether each promised good or service is immaterial in the context of the
contract. In assessing materiality, management considers quantitative factors by
comparing standalone selling price of the promised good or service to the total
consideration in the contract and qualitative factors, such as the importance of
the promised good or service to the customer.

We assess whether each material 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 and the 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.

Arrangements that include rights to additional goods or services that are
exercisable at a customer's discretion are generally considered options. We
assess if these options provide a material right to the customer and if so, they
are considered performance obligations. The identification of material rights
requires judgments related to the determination of the value of the underlying
license relative to the option exercise price, including assumptions about
technical feasibility and the probability of developing a candidate that would
be subject to the option rights. The exercise of a material right is accounted
for as a contract modification for accounting purposes.

                                       97

--------------------------------------------------------------------------------

Determine the Transaction Price



In determining the transaction price, we consider fixed considerations, variable
considerations, non-cash considerations, significant financing components, and
any consideration payable to the customer. If the consideration promised in a
contract includes a variable amount, we estimate the amount of consideration to
which we 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
unconstrained amount of estimated variable consideration in the transaction
price. The amount included in the transaction price is constrained to the amount
for which it is probable that a significant reversal of cumulative revenue
recognized will not occur. At the end of each subsequent reporting period, we
re-evaluate the estimated variable consideration included in the transaction
price and any related constraint, and if necessary, adjust our estimate of the
overall transaction price. Any such adjustments are recorded on a cumulative
catch-up basis in the period of adjustment.

If an arrangement includes development and regulatory milestone payments, we
evaluate whether the milestones are considered probable of being reached and
estimate the amount to be included in the transaction price using the most
likely amount method. If it is probable that a significant revenue reversal
would not occur, the associated milestone value is included in the transaction
price. Milestone payments that are not within our control or the licensee's
control, such as regulatory approvals, are generally not considered probable of
being achieved until those approvals are received.

In determining the transaction price, we adjust consideration for the effects of
the time value of money if the timing of payments provides us with a significant
benefit of financing. 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 our revenue
generating arrangements in order to determine whether a significant financing
component exists.

Allocate the Transaction Price to the Performance Obligations



Once the transaction price is then determined, it is allocated to the identified
performance obligations in proportion to their standalone selling prices, or
SSP, on a relative SSP basis. SSP is determined at contract inception and is not
updated to reflect changes between contract inception and when the performance
obligations are satisfied. Determining the SSP for performance obligations
requires significant judgment. In developing the SSP for a performance
obligation, we consider applicable market conditions and relevant
entity-specific factors, including factors that were contemplated in negotiating
the agreement with the customer and estimated costs. We validate the SSP for
performance obligations by evaluating whether changes in the key assumptions
used to determine the SSP will have a significant effect on the allocation of
arrangement consideration between multiple performance obligations.

Determine When to Recognize Revenue



We then 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, and if over
time recognition is based on the use of an output or input method.

For arrangements with licenses of intellectual property that include sales-based
royalties, including milestone payments based on the level of sales, and the
license is deemed to be the predominant item to which the royalties relate, we
recognize 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.

For arrangements with research and development services to be performed by us,
revenue allocated to our performance obligation is generally recognized based on
an appropriate measure of progress. We utilize judgment to determine the
appropriate method of measuring progress for purposes of recognizing revenue,
which is generally an input measure, such as costs incurred. We evaluate the
measure of progress each reporting period and, if necessary, adjust the measure
of performance and related revenue recognition. The measure of progress, and
thereby periods over which revenue should be recognized, are subject to
estimates by management and may change over the course of the arrangement.

Prepaid and Accrued Research and Development Expenses



As part of preparing the consolidated financial statements, we are required to
estimate our accrued research and development expenses. This process involves
reviewing quotations and contracts, identifying services that have been
performed on our behalf and estimating the level of service performed and the
associated cost incurred for the service when we have not yet been invoiced or
otherwise notified of the actual cost. We make estimates of the accrued expenses
as of each balance sheet date in our consolidated financial statements based on
facts and circumstances known to us at that time. In addition, 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 which case such
amounts are reflected as prepaid expenses and other current assets. In accruing
service fees, we estimate the time period over which services will be performed
and the level of effort to be

                                       98

--------------------------------------------------------------------------------
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 the
amount of prepaid expenses accordingly. Although we do not expect our estimates
to be materially different from amounts actually incurred, our understanding of
the status and timing of services performed relative to the actual status and
timing of services performed may vary and could result in us reporting amounts
that are too high or too low in any particular period.

Non-refundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized in prepaid expenses and other current assets. The capitalized amounts are expensed as the related goods are delivered or the services are performed.

Stock Options



We account for all stock-based compensation awards granted to employees
and non-employees as stock-based compensation expense at fair value. Our
stock-based payments include stock options and grants of common stock, including
common stock subject to vesting. The measurement date for awards is the date of
grant, and stock-based compensation costs are recognized as expense over the
requisite service period, which is generally the vesting period, on a
straight-line basis. Stock-based compensation expense is classified in the
consolidated statements of operations and comprehensive loss based on the
function to which the related services are provided. We recognize stock-based
compensation expense for the portion of awards that have vested. Forfeitures are
recorded as they occur. The fair value of each stock option grant is estimated
on the date of grant using the Black-Scholes option-pricing model. The
Black-Scholes option pricing model includes various assumptions, including the
expected term of the award, the expected volatility and the expected risk-free
interest rate over the expected term of the award, expected dividend payments,
and estimated forfeitures.

• Expected term: We use the "simplified method" as prescribed by Securities

and Exchange Commission Staff Accounting Bulletin No. 107, Share Based

Payments, to estimate the expected term of stock option grants. Under this

approach, the weighted-average expected life is presumed to be the average

of the contractual term of ten years and the weighted-average vesting term

of the stock options, taking into consideration multiple vesting tranches.

We utilize this method due to lack of historical data and the plain-vanilla

nature of our share-based awards.

• Volatility: We use a weighted-average of expected volatility for a period

equal to the expected term of the option grant, based on the volatilities of

a representative group of publicly traded biopharmaceutical companies. For

options granted subsequent to our IPO, the volatility is based on

volatilities of a representative group of publicly traded biopharmaceutical

companies and our own volatility.

• Risk-free rate: The risk-free rate is based on the yield curve of U.S.

Treasury securities with periods commensurate with the expected term of the

options being valued.




   •  Dividends: We have never paid, and do not anticipate paying, any cash
      dividends in the foreseeable future, and, therefore, use an expected
      dividend yield of zero in the option-pricing model.

• Forfeitures: We account for forfeitures as they occur and, therefore, do not

estimate forfeitures.




In addition to the above, inputs, the fair value of the underlying common stock
represents the exercise price utilized in the Black-Scholes option pricing
model. These assumptions reflect our best estimates, but they involve inherent
uncertainties based on market conditions generally outside our control. As a
result, if other assumptions had been used, stock-based compensation cost could
have been materially impacted. Furthermore, if we use different assumptions for
future grants, stock-based compensation cost could be materially impacted in
future periods.

Determination of the fair value of our common stock issued prior to our IPO



As there has been no public market for our common stock prior to our IPO, the
estimated fair value of our common stock was determined by our board of
directors as of the date of each stock award, with input from management,
considering our most recently available third-party valuations of our common
stock. Valuations were updated when facts and circumstances indicated that the
most recent valuation was no longer valid, such as changes in the stage of our
development efforts, various exit strategies and their timing, and other
scientific developments that could be related to the valuation of our company
or, at a minimum, annually. Third-party valuations 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 valuations in 2019
were prepared using a market approach, specifically the guideline public company
method, which "back-solves" to a common stock price. We allocated equity value
to our common stock and shares of our redeemable convertible preferred stock,
using either an option-pricing method, or OPM, or a hybrid method, which is a
hybrid between the OPM and the probability-weighted expected return method. The
hybrid method estimates the probability-weighted value across multiple
scenarios. In addition to the OPM, the hybrid method considers liquidity
scenarios in which the shares of our redeemable convertible preferred stock are
assumed to convert into

                                       99

--------------------------------------------------------------------------------
common stock. The future value of the common stock in the applicable scenario
was discounted back to the valuation date at an appropriate risk-adjusted
discount rate. In the hybrid method, the present value indicated for each
scenario was probability-weighted to arrive at an indication of value for the
common stock. In addition to considering the results of these third-party
valuations, 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:

• prices at which we sold shares of our preferred stock and the superior

rights and preferences of the preferred stock relative to our common stock

at the time of each grant;

• the progress of our preclinical and clinical development, including the

status and results of preclinical studies for our product candidates;

• our stage of development and our business strategy and the material risks

related to our business and industry;

• external market conditions affecting the biopharmaceutical industry and the

material risks related to our business and industry; and trends within the

biopharmaceutical 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 preferred

stock;

• the likelihood of achieving a liquidity event, such as an IPO or sale of our

company in light of prevailing market conditions; and

• the analysis of IPOs and the market performance of similar companies in the

biopharmaceutical industry.

The assumptions underlying these valuations represent management's best estimates, which involve inherent uncertainties and the application of management judgement. As a result, if factors or expected outcomes change and we use significantly different assumptions or estimates, our stock-based compensation could be materially different.

Determination of the fair value of our common stock issued subsequent to our IPO

Following our IPO, the fair value of our common stock was determined based on the quoted market price of our common stock.

New Accounting Pronouncements



For information on new accounting standards, see Note 2, Summary of significant
accounting policies, to our consolidated financial statements in this Annual
Report on Form 10-K.

Off-Balance Sheet Arrangements

We have not entered into any off-balance sheet arrangements and do not have any holdings in variable interest entities.

Internal Control over Financial Reporting



In the preparation of our consolidated financial statements to meet the
requirements of our IPO, we determined that a material weakness in our internal
control over financial reporting existed as of December 31, 2019. The material
weakness identified in our internal control over financial reporting arose
because we did not maintain effective segregation of duties in the process and
recording of journal entries. As of December 31, 2020, we remediated the
material weakness by engaging system controls that prevent one person from
initiating and approving the same journal entry. In addition, we implemented and
performed additional reviews and other post-closing procedures. While we believe
that this material weakness has now been remediated, we cannot assure you that
these measures will be sufficient to prevent future material weaknesses or
significant deficiencies in our internal control over financial reporting from
occurring. See "Risk Factors-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."

Emerging Growth Company Status



As an "emerging growth company," the Jumpstart Our Business Startups Act of
2012, or the JOBS Act, allows us to delay adoption of new or revised accounting
standards applicable to public companies until such standards are made
applicable to private companies. We have elected to avail ourselves of this
extended transition period for complying with new or revised accounting
standards until the earlier of the date that we (i) are no longer an emerging
growth company or (ii) affirmatively and irrevocably opt out of this extended
transition period. Accordingly, the information contained herein may be
different from the information you receive from other public companies that are
not emerging growth companies. in which you hold stock.

                                      100

--------------------------------------------------------------------------------

In addition, as an emerging growth company, we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

• being permitted to only provide two years of audited financial statements in

addition to any required unaudited interim financial statements with

correspondingly reduced "Management's Discussion and Analysis of Financial

Condition and Results of Operations" disclosure;

• reduced disclosure about the compensation paid to our executive officers;




   •  not being required to submit to our stockholders' advisory votes on
      executive compensation or golden parachute arrangements; and

• an exemption from the auditor attestation requirement in the assessment of

our internal control over financial reporting pursuant to the Sarbanes-Oxley

Act of 2002.




We may take advantage of these exemptions for up to the last day of 2025 or such
earlier time that we are no longer an emerging growth company. We would cease to
be an emerging growth company on the date that is the earliest of (1) the last
day of the fiscal year in which we have total annual gross revenues of
$1.07 billion or more; (2) the last day of 2025; (3) the date on which we have
issued more than $1.0 billion in nonconvertible debt during the previous three
years; or (4) the date on which we are deemed to be a large accelerated filer
under the rules of the Securities and Exchange Commission. We may choose to take
advantage of some but not all of these exemptions.
