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 clinical-stage biopharmaceutical company dedicated to advancing
targeted protein degradation science to develop a new generation of
small-molecule medicines to transform how disease is treated. We leverage our
proprietary technology platform, TORPEDO (Target ORiented ProtEin Degrader
Optimizer), to efficiently design and optimize small-molecule medicines that
harness the body's natural protein recycling system to rapidly degrade
disease-causing protein, offering the potential to overcome drug resistance,
drug undruggable targets and improve patient outcomes. We are using our TORPEDO
platform to advance multiple targeted oncology programs to the clinic while
expanding the platform to deliver the next wave of medicines for
difficult-to-treat diseases.

Our most advanced product candidate, CFT7455, is an orally bioavailable MonoDAC
degrader of protein targets called IKZF1 and IKZF3, currently in clinical
development 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 initiated a first-in-human Phase 1/2 clinical trial for this product
candidate in June 2021 and a number of sites are presently open and enrolling
patients.

We are also developing CFT8634, an orally bioavailable BiDAC degrader of a
protein target called BRD9, for synovial sarcoma and SMARCB1-deleted solid
tumors. In December 2021, the FDA cleared the IND application for CFT8634, and
we expect to dose the first patient in a first-in-human Phase 1/2 clinical trial
of this product candidate in the first half of 2022.

Further, we are developing CFT1946, an orally bioavailable BiDAC degrader
specifically targeting V600X mutant BRAF to treat melanoma, non-small cell lung
cancer, or NSCLC, colorectal cancer and other solid malignancies that harbor
this mutation. We expect to submit an IND for this product candidate and begin a
first-in human Phase 1/2 clinical trial in BRAF V600X driven cancers including
melanoma, NSCLC and colorectal cancer in the second half of 2022. In November
2021, we regained rights to our BRAF program from Roche after our companies
mutually agreed to terminate our agreement solely with respect to the BRAF
target, enabling us to move this program forward independently.

Additionally, we are developing CFT8919, an orally bioavailable, allosteric,
mutant-selective BiDAC degrader of epidermal growth factor receptor, or EGFR,
with an L858R mutation in NSCLC. We expect to complete IND-enabling activities
for this product candidate by the end of 2022.

Beyond these initial product candidates, we are further diversifying our
pipeline by developing new degraders against both clinically-validated and
currently undruggable targets. We have engineered degraders that have
successfully achieved blood-brain barrier penetration in preclinical studies,
which is a key step in developing medicines with the potential to treat brain
metastases in oncology as well as in therapeutic areas such neurodegenerative
diseases. We also believe there are many other therapeutic areas and indications
where leveraging our TORPEDO platform to develop novel degraders may be
advantageous.

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 $83.9 million, $66.3 million, and $34.1
million for the years ended December 31, 2021, 2020, and 2019 respectively. As
of December 31, 2021, we had an accumulated deficit of $267.7 million.

Our total operating expenses were $127.9 million, $93.6 million, $56.8 million
and for the years ended December 31, 2021, 2020, and 2019 respectively. We
expect to continue to incur significant expenses and increasing operating losses
for at least the next several years. We anticipate that our expenses will
increase substantially if and as we:

• initiate, conduct, and successfully complete first-in-human and later-stage

clinical trials of our product candidates and as we expand the scope of our

proprietary research and development portfolios;

• leverage our TORPEDO platform to discover and then advance additional


      product candidates into preclinical and clinical development;


  • expand the capabilities of our TORPEDO platform;


                                       84

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

• seek marketing approvals for any product candidates that successfully

complete clinical trials;

• 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;


  • expand, maintain and protect our intellectual property portfolio;

• hire additional personnel, including in areas such as clinical development,

regulatory, quality, scientific, and general and administrative positions;

and

• add operational, financial and management information systems and personnel,

including personnel to support our ongoing research and development and

potential future commercialization efforts.




As a result of these anticipated expenditures, we will need substantial
additional funding to support our operations. 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.

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.

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 the
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 a license agreement, or the Original Roche
Agreement, with F. Hoffmann-La Roche Ltd and Hoffmann-La Roche Inc., or 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 $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 products related to the targets
included in the collaboration, whereby if we elect to opt into certain
co-development rights, we will receive an increased royalty rate on future
product sales from commercializing products directed to the target. If we opt
into certain co-detailing rights, we are entitled to reimbursement of certain
commercialization costs. 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 products related to these six
targets.

In November 2020, we signed a further amendment to the Roche Agreement that
created 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

                                       85
--------------------------------------------------------------------------------
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 Target Termination Agreement. Through the entry into this amendment, we
and Roche mutually agreed to terminate the Roche Agreement as to the target EGFR
and, in November 2021, we entered into a Mutual Target Termination Agreement
with Roche through which we agreed to terminate the Roche Agreement as to the
target BRAF. Following this mutual target termination decision, the number of
targets on which the parties shall continue to collaborate has been reduced to
four, with Roche maintaining its option rights to license and commercialize
products directed to those four targets. As a result, Roche is now free to
pursue the targets EGFR and BRAF in the Roche Field and we are free to pursue
the targets EGFR and BRAF in the C4T Field. All rights in and responsibility for
know-how and intellectual property related to EGFR and BRAF in the Roche Field
reverted to the Roche parties and all rights in and responsibility for know-how
and intellectual property related to EGFR and BRAF in the C4T Field reverted to
us, with Roche is in the process of assigning the relevant patents in the C4T
Field to us.

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 standard good
laboratory practice, or 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.

Biogen Collaboration Research and License Agreement



On December 28, 2018, we entered into a collaborative research and license
agreement, or the Biogen Agreement, with Biogen MA, Inc., or 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 commercialize the products related to 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, ending in June 2023,
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 products related to the targets

                                       86

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

for commercialization; the receipt of these payments is contingent on the further development of products directed to the targets to commercialization by Biogen, without any additional research and development efforts from us.



Biogen also had the option to fund additional discovery activities, referred to
as sandbox activities, whereby we performed 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. Sandbox activities fully concluded on August 31, 2021.
Revenues earned under this option, were recognized as services were performed
and were not included in the transaction price at the outset of the arrangement.
These research activities were reimbursed on a full-time equivalent, or FTE,
basis at specified market rates. These additional discovery activities were
purchased up to a maximum amount by Biogen on an à la carte basis at an amount
consistent with standalone selling price. If Biogen exercised these options, we
recognized revenue as those options were exercised.

Calico License Agreement



In March 2017, we entered into Collaboration and License Agreement, or the
Calico Agreement, with Calico Life Sciences LLC, or 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. In August 2021, we provided Calico with
an option to extend the research term with respect to a certain program for up
to a one-year period ending in March 2023, such period referred to as the
research term. In September 2021, Calico elected to exercise the option for a
one-year extension of the research term for this specified program.

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 applicable 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, with the term for one research
program having been extended by an additional year.

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 development of that target to
commercialized product. 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 products related to
targets for commercialization; the receipt of these payments by us is contingent
on the further development of the targets to commercialized products 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,

preclinical, and clinical activities on our behalf as well as third parties


      that manufacture our product candidates for use in our preclinical and
      clinical trials;

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

and related travel expenses;


                                       87
--------------------------------------------------------------------------------

• 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 continue to 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 continue to increase
in the future to support increased research and development activities. These
increases will likely include increased costs related to the hiring of
additional personnel; fees to outside consultants, lawyers and accountants;
director and officer insurance costs, among other expenses. and investor and
public relations costs.

Other (Expense) Income

Other (expense) income, net primarily consists of the following:

• interest expense and amortization of our long-term debt, and change in the

fair value of warrant liability, which are discussed in greater detail in

Note 9, Long-term debt and warrant - related party; and

• interest income earned on our cash, cash equivalents, and marketable

securities and accretion of discount on marketable securities.

Total revenue from collaboration agreements $ 45,785 $ 33,195 $ 21,381

The $12.6 million increase in revenue in the year ended December 31, 2021 as compared to the year ended December 31, 2020 is primarily driven by:

• a $10.3 million increase in revenue recognized under the Roche Agreement


      primarily as a result of the termination of the Roche Agreement as to the
      BRAF target;


                                       88

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

• a $5.8 million increase in revenue recognized under the Biogen Agreement due

to additional work on the nominated targets and, as a result, additional


      revenue recognized from the $6.0 million of milestones earned during the
      year; and


These were offset by a $3.5 million decrease in revenue recognized under the
Calico Agreement, primarily driven by a decrease in FTE reimbursements and the
impact of the one-year extension of the term of the Calico Agreement's with
respect to one of the research programs in that collaboration.

The $11.8 million increase in the year ended December 31, 2020 as compared to the year ended December 31, 2019 primarily stems from:

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

to additional work on three targets;

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

additional revenue recognized from the $4.0 million milestone earned in June


      2020, additional work on the initial three targets nominated, and an
      increase in sandbox related revenue of $2.3 million; and

• a $1.7 million increase in revenue recognized under the Calico Agreement

primarily related to additional FTE reimbursement received in 2020 resulting

from additional work on Calico targets.

Total research and development expenses $ 94,665 $ 78,440 $ 48,059

The $16.2 million increase in research and development expense in the year ended December 31, 2021 from the year ended December 31, 2020 is primarily driven by:

• a $4.0 million increase in preclinical and development costs, primarily


      driven by an increase of $2.9 million of IND-enabling study costs and an
      increase in preclinical development costs of our various programs;

• a $9.0 million increase in personnel expenses, representing salary and

benefit costs, including a $6.5 million increase in stock-based compensation

expense driven primarily by the increase in the fair value of our stock, and

due to the buildout of our clinical development team; and

• a $2.7 million increase in clinical costs resulting from the initiation of a

Phase 1/2 clinical trial of CFT7455 in June 2021.

The $30.4 million increase in research and development expense for the year ended December 31, 2020 from the year ended December 31, 2019 was primarily due to:

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

$11.9 million increase in preclinical development costs of our various


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

• 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.

Total general and administrative expenses $ 33,254 $ 15,204 $ 8,774

The $18.1 million increase in general and administrative expense in the year ended December 31, 2021 as compared to the year ended December 31, 2020 is primarily driven by:

• a $15.1 million increase in personnel expenses, representing salary and

benefit costs, including a $11.5 million increase in stock-based

compensation expenses driven primarily by the increase in the fair market

value of our stock, partially offset by lower severance expense in the

current period compared to severance expense recognized in the three months


      ended March 31, 2020 resulting from the departure of our former Chief
      Executive Officer; and

• a $2.6 increase in professional fees, which is driven primarily by increased


      insurance costs, consultant fees, and legal and audit fees, resulting from
      our transition to a public company.

The $6.4 million increase in general and administrative expense in the year ended December 31, 2020 from the year ended December 31, 2019 was primarily due to:

• 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.




Other (Expenses) Income

The following table summarizes our other (expense) income (in thousands):



                                                        Years Ended December 31,

Total other (expense) income, net               $   (1,758 )   $   (6,512 )

$ 2,157




The $4.8 million change in other (expenses) income for the years ending
December 31, 2021 as compared to the year ending December 31, 2020 was driven by
the $5.7 million charge we incurred during the year-ended December 31, 2020 due
to the increase in fair value of warrant liability associated with our long-term
debt. This was partially offset by an increase of $0.9 million change resulting
from interest expense and amortization of the discount related to our long-term
debt, which was outstanding for the full year ended December 31, 2021.

The $8.7 million increase in interest and other income (expenses) for the year
ending December 31, 2020 as compared to the year ending December 31, 2019 was
primarily due to:

• 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.

Liquidity and Capital Resources

Sources of Liquidity



Since inception, we have incurred significant operating losses. We expect to
incur significant expenses and operating losses for the foreseeable future as we
continue 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,
public offerings of our common stock, and through payments from collaboration
partners. As of December 31, 2021, we had cash, cash equivalents and marketable
securities of approximately $451.5 million.

In June 2020 and July 2020, we closed the sale of shares of our Series B
preferred stock, or the 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 at a purchase price of $1.05 per
share, for aggregate net proceeds of $145.5 million. Upon completion of the IPO,
all of our redeemable convertible preferred stock was automatically converted
into shares of our common stock at a rate of 8.4335 shares of redeemable
convertible preferred stock to 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 had the option to draw down
another $7.5 million. Our ability to draw down on this second tranche expired on
June 30, 2021.

In October 2020, we completed our IPO in which we issued and sold 11,040,000
shares of common stock at a price to the public of $19.00 per share. The net
proceeds from our IPO, including the full exercise of the underwriter's
overallotment option, were approximately $191.2 million.

In June 2021, we completed a follow-on public offering, at which time we sold
4,887,500 shares of our common stock, which number includes 637,500 shares of
common stock that were issued to the underwriters when they exercised in full
their overallotment option. Net proceeds from the follow-on offering, including
the exercise in full of the underwriters' option to purchase additional shares,
were $169.5 million, after deducting underwriting discounts and commissions, and
estimated expenses of $11.3 million.

In November 2021, we filed an automatically effective registration statement on
Form S-3, or the Registration Statement, with the SEC which registers the
offering, issuance and sale of an unspecified amount of common stock, preferred
stock, debt securities, warrants and/or units of any combination thereof. We
simultaneously entered into an equity distribution agreement with Cowen and
Company, LLC, as sales agent, to provide for the issuance and sale by us of up
to $200.0 million of common stock from time to time in "at-the-market" offerings
under the Registration Statement and related prospectus filed with the
Registration Statement, or the ATM Program. As of December 31, 2021, no such
sales have been made under the ATM Program.

      under our collaboration agreements;


  • a $6.1 million change in prepaid expenses and other current assets;


  • a $1.2 million change in accounts receivable; and


  • a $1.2 million change in accounts payable.


                                       91

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

These amounts were offset by:

• a $26.3 million of non-cash expense related to stock compensation expense,


      depreciation, accretion of discount on investments, and reduction in
      carrying amount of our right-of-use asset; and


  • a $4.4 million change in accrued expenses and other liabilities.

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

      under our collaboration agreements; and


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

These amounts 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 primarily consist of:

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

of up-front payments from our collaboration partners;

• an $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; and

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

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

These amounts were offset by:

• our net loss of $34.1 million; and

• a $3.2 million change in deferred revenue due to the recognition of revenue

under our collaboration agreements in 2019.

Investing Activities

The $189.3 million of net cash used in investing activities for the year ended December 31, 2021 was attributable to:

$188.1 million for the purchases of marketable securities, net of
       maturities; and


  • $1.3 million for the purchases of property and equipment.

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 purchases of property and equipment; and

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




Financing Activities

The $171.4 million of net cash provided by financing activities for the year ended December 31, 2021 is primarily driven by:

$169.5 million of proceeds from our follow-on offering, net of issuance


      costs paid; and


  • $2.3 million of proceeds from exercises of stock options.

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;


                                       92
--------------------------------------------------------------------------------

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

costs; and

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


      of issuance costs.


Funding Requirements

Since our inception, we have incurred significant operating losses and 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, we expect to continue to incur costs
associated with operating as a public company.

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

• continue our ongoing first-in-human Phase 1/2 trials of CFT7455 and initiate


      and conduct planned first-in-human Phase 1/2 trials for our other lead
      product candidates;


   •  advance additional product candidates into preclinical and clinical
      development;


  • continue to invest in our proprietary TORPEDO platform;

• advance, expand, maintain and protect our intellectual property portfolio;

• hire additional clinical, regulatory, quality 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 ongoing and 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 progress and 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;

• 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, that 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

                                       93
--------------------------------------------------------------------------------
committed external source of funds as of December 31, 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.

If 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, 2021 (in thousands):



                                                     Less than       1 to 3       4 to 5       More than

Total contractual obligations $ 117,288 $ 7,349 $ 29,899 $ 18,459 $ 61,581

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

Watertown, Massachusetts office and laboratory space, including an additional

space for which rent will commence in March 2022. The lease term is expected

to expire in February 2032.




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.

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.

We consider the pattern of satisfaction of the performance obligations under
step (v) above to be a critical accounting estimate. More specifically, the
determination of the level of achievement of research and development service
performance

                                       94

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

obligations, whose pattern of satisfaction is measured using costs incurred to date as compared to total costs incurred and expected to be incurred in the future is driven by a critical accounting estimate.



In estimating the costs expected to be incurred in the future, management uses
its most recent budget and long-range plan, adjusted for any pertinent
information. While this is our best estimate as of the reporting period, costs
expected to be incurred in the future require management judgment as the scope
and timing of research and development activities may change significantly over
time. We may adjust the scope of our research and development activities based
on several factors, such as additional work needed to support advancement of
product candidate or change in the number of patients in trials. Further,
research and development services may no longer be within the scope of a
collaboration agreement, as has been the case with certain of our programs. The
timing of when research and development costs are expected to be incurred may
change as a result of external factors, such as delays caused by manufacturing
or supply chain, or difficulty in enrolling patients; or internal factors, such
as prioritization of programs. Our estimate of the scope and timing of research
and development services performed relative to the actual scope and timing may
have a significant impact on revenue recognition.

Prepaid and Accrued Research and Development Expenses



As part of preparing our 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 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 have a significant impact on reported amounts.

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.

Operating Leases (Incremental Borrowing Rate)



We account for leases in accordance with ASC Topic 842, Leases, or ASC 842.
Under ASC 842, at inception or upon modification of a lease arrangement, we may
be required to remeasure our lease liabilities and the corresponding
right-of-use assets. The lease liability is measured by calculating the present
value of lease payments under the lease arrangement using the incremental
borrowing rate. Incremental borrowing rate is the rate of interest that we would
have to pay to borrow, on a collateralized basis, an amount equal to the lease
payments over a similar term equal to the lease term in a similar economic
environment.

Since the incremental borrowing rates implicit in our leases are not readily
determinable, we use an estimated incremental borrowing rates based on the
information available at commencement date in determining the discount rate used
to calculate the present value of lease payments. As we have no recent external
borrowings, the incremental borrowing rates are determined using information on
indicative borrowing rates that would be available to us based on the value and
borrowing term provided by financial institutions, adjusted for company and
market specific factors. This determination requires management judgement,
including when determining peer groups, our own risk profile, and when adjusting
for company and market specific factors.

Although we do not expect our estimates of the incremental borrowing rates to
generate material differences within a reasonable range of sensitivities,
judgement is involved in selecting an appropriate rate, and the rate selected
for our leases will have an impact on the value of the lease liability and
corresponding right-of-use asset in the consolidated balance sheets.

Stock Options



We account for all stock-based awards granted to employees and non-employees as
stock-based compensation expense at fair value. Our stock-based payments include
stock options, restricted stock units, 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

                                       95
--------------------------------------------------------------------------------
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 the fair
value of the common stock underlying the stock-based award.

We consider the expected volatility to be a critical accounting estimate. As we
do not have sufficient trading history, we use the average historical volatiles
of a representative group of publicly traded biopharmaceutical companies,
including our own, to calculate the expected volatility for use in the
Black-Scholes option pricing model. This assumption reflects our best estimate,
but it involves inherent uncertainties based on market conditions generally
outside our control. As a result, if a different volatility had been used,
stock-based compensation cost could have been materially impacted.

Determination of the Fair Value of Our Common Stock Issued Prior to Our IPO



In the periods prior to our IPO, we also considered the determination of the
fair value of our common stock to be a critical accounting estimate. As there
had been no public market for our common stock prior to our IPO, the estimated
fair value of our common stock was determined as of the date of each stock award
by our board of directors 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 prior to our IPO were prepared using a
market approach, specifically the guideline public company method, which
"back-solves" to a common stock price.

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.

New Accounting Pronouncements



We became a large accelerated filer on December 31, 2021 based on the market
value of our common stock held by non-affiliates as of the last day of the
second quarter in 2021. Prior to that, we were an emerging growth company, or
EGC, as defined in the Jumpstart Our Business Startups Act, or the JOBS Act.
Being an EGC allowed us to delay adoption of new or revised accounting
pronouncements applicable to public companies until such pronouncements are made
applicable to private companies. We had elected to take advantage of certain
exemptions from various reporting requirements and use this extended transition
period under the JOBS Act until we are no longer an EGC.

We lost the ability to delay adoption of new or revised accounting
pronouncements when we became a large accelerated filed as of December 31, 2021.
As a result, the financial statements included in this Form 10-K reflect the
adoption of new accounting standards effective for calendar year end public
companies.

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 initiating 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
