<b>10. Convertible Notes</b></p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">
In September 2014, the Company entered into a bridge loan financing
with various investors, in which it issued convertible unsecured
promissory notes for an aggregate principal amount of $5.0 million
(the “2014 Notes”), in two closings. The first closing
occurred in September 2014 and $4.9 million was received, and the
balance of $0.1 million was received in October 2014. The 2014
Notes accrued interest at 6% per annum and had a maturity date
of September 30, 2015 (the “Maturity Date”). The
2014 Notes were convertible upon the occurrence of the certain
events during the period that the loans are outstanding. In June
2015, in conjunction with the Series C-1 financing, the outstanding
principal of $5.0 million of the 2014 Notes and the related accrued
interest of $0.2 million were converted into 372,446 shares of
Series C-1 at $14.00 per share, which was the same price paid by
Series C-1 investors.</p>

<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">
The Company has prepared the accompanying consolidated financial
statements in conformity with accounting principles generally
accepted in the United States of America (“U.S.
GAAP”).</p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">
On February 24, 2016, the Company effected a 1-for-1.25
reverse stock split of the Company’s outstanding common stock
and convertible preferred stock; and on June 3, 2014, the
Company effected a 1-for-12.3 reverse stock split of the
Company’s outstanding common stock and convertible preferred
stock. Stockholders entitled to fractional shares as a result of
the reverse stock splits received a cash payment in lieu of
receiving fractional shares. All of the Company’s historical
share and per share information shown in the accompanying financial
statements and related notes have been retroactively adjusted to
give effect to these reverse stock splits.</p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">
In 2011, the Company established a wholly owned subsidiary in the

<b><i>Debt Discount</i></b></p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">
The Company has recorded the fair value of the derivative liability
related to its term loans as debt discount, which is presented in
the consolidated balance sheets as an offset to the carrying value
amount of the debt. Debt discount is amortized to interest expense
using the effective interest rate method or a method that
approximates the effective interest rate method over the expected
period that the debt is expected to be outstanding. In October
2015, the Company prepaid the outstanding balance on the term loans
and wrote off the unamortized debt discount related to the term
loans.</p>

Cash and cash equivalents, restricted cash, and short-term
investments are financial instruments that potentially subject the
Company to concentrations of credit risk. Substantially all of the
Company’s cash, cash equivalents, and short-term investments
were deposited in accounts at two financial institutions, and at
times, such deposits may exceed federally insured limits. The
Company has not experienced any losses in such accounts, and
management believes that the Company is not exposed to significant
credit risk due to the financial position of the depository
institutions in which those deposits are held. The Company’s
available-for-sale investments primarily consist of U.S. Treasury
securities, U.S. government agency securities, corporate debt
securities, certificates of deposit and overnight deposits and
potentially subject the Company to concentrations of crdit
risk.</p>

<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
In September 2015, the Company’s board of directors adopted
its 2015 Omnibus Incentive Plan (“2015 Plan”), which
was subsequently approved by its stockholders and became effective
upon the closing of the IPO on March 8, 2016. The 2015 Plan
replaces the 2007 Stock Plan (“2007 Plan”) and allows
for the granting of incentive stock options, nonqualified stock
options, stock appreciation rights, restricted stock, unrestricted
stock, stock units, dividend equivalent rights, performance awards,
annual incentive awards, and other equity-based awards to the
Company’s executives and other employees, non-employee
members of the board of directors, and consultants of the Company.
Any options or awards outstanding under the Company’s 2007
Plan remain outstanding and effective. Any shares of common stock
related to awards outstanding under the 2007 Plan that thereafter
terminate by expiration, forfeiture, cancellation or otherwise
without the issuance of such shares will be added to, and included
in, the 2015 Plan reserve amount. The Company initially reserved
1,750,000 shares of its common stock for the issuance of awards
under the 2015 Plan. As of December 31, 2016, there were
1,465,229 shares available for issuance under the 2015 Plan.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
The 2015 Plan provides that the number of shares reserved and
available for issuance under the 2015 Plan will automatically
increase each January 1, beginning on January 1, 2017, by
4% of the outstanding number of shares of common stock on the
immediately preceding December 31 or such lesser number of
shares as determined by the Company’s board of directors. On
January 1, 2017, the shares available for issuance under the
2015 Plan were increased to 4,754,914.</p>

As of December 31, 2016, there was $7.8 million of
unrecognized compensation cost related to employee and non-employee
unvested stock options and unvested restricted stock granted under
the 2007 and 2015 Plans, which is expected to be recognized over a
weighted-average remaining service period of 2.5 years. Stock
compensation costs have not been capitalized by the Company.</p>

The fair value of each option award is estimated on the date of
grant using the Black-Scholes option-pricing model with the
weighted-average assumptions noted in the table below. Expected
volatility for the Company’s common stock was determined
based on an average of the historical volatility of a peer group of
similar public companies. The Company estimated the expected term
of its employee service-based stock options using the
“simplified” method, whereby, the expected term equals
the average of the vesting term and the original contractual term
of the option. The contractual life of the option was used for the
estimated life of the non-employee grants. The assumed dividend
yield is based upon the Company’s expectation of not paying
dividends in the foreseeable future. The risk-free interest rate
for periods within the expected life of the option is based upon
the U.S. Treasury yield curve in effect at the time of grant. The
accounting guidance for stock-based compensation requires
forfeitures to be estimated at the time of grant and revised, if
necessary, in subsequent periods if actual forfeitures differ from
those estimates. The grant date fair values of options issued to
employees and non-employees were estimated using the Black-Scholes
option-pricing model with the following assumptions:</p>

In determining the exercise prices for options granted, the Board
has considered the fair value of the common stock as of each grant
date. Prior to our IPO, the fair value of the common stock
underlying the stock options has been determined by the Board at
each award grant date based upon a variety of factors, including
the results obtained from an independent third-party valuation, the
Company’s financial position and historical financial
performance, the status of technological developments within the
Company’s products, the composition and ability of the
current clinical and management team, an evaluation or benchmark of
the Company’s competition, the current business climate in
the marketplace, the illiquid nature of the common stock,
arm’s-length sales of the Company’s capital stock
(including convertible preferred stock), the effect of the rights
and preferences of the preferred stockholders, and the prospects of
a liquidity event, among others.</p>

The 2007 Plan allowed employees to exercise unvested options in
exchange for restricted common stock. Such arrangements permitted
the Company to subsequently repurchase such shares at the exercise
price if the vesting conditions were not satisfied. Such an
exercise is not substantive for accounting purposes; therefore, the
payment received by the Company for the exercise price is
recognized as an early exercise liability on the Company’s
consolidated balance sheet and will be transferred to common stock
and additional paid-in capital as such shares vest. The Company
issued 16,731 shares of restricted common stock upon early exercise
of stock options during the year ended December 31, 2015, with
total proceeds of $0.1 million on the exercise date. As of
December 31, 2016, 8,542 unvested shares were legally issued
and outstanding and subject to repurchase by the Company. In
connection with these unvested shares, the Company has recorded a
liability of $0.1 million, of which $42,000 is included in accrued
expenses and other current liabilities and $17,000 is included in

In September 2016, the Company entered into a new five-year
operating lease for approximately 12,207 square feet of office
space in Waltham, Massachusetts, with a lease commencement date of
March 1, 2017, and an option to extend the lease term once for
an additional three years. The Company also has an option to cancel
the lease after three years with the termination fee consisting of
$55,000. The Company’s existing Waltham lease expires in
April 2017 and will relocate to the new space on March 1,
2017. The lease has monthly lease payments of $25,000 the first 12
months with annual rent escalations thereafter and provides a rent
abatement of $0.2 million for the first year. The Company will
record the lease abatement as deferred rent and will amortize these
amounts on a straight-line basis as a reduction of rent expense
over the lease term. The Company paid the landlord a security
deposit of $0.1 million in 2016, which will be returned without
interest at the end of the lease. The Company recorded the security
deposit as a long-term deposit on its consolidated balance
sheet.</p>

abatement of $18,000 per month for the first two months. The
Company also has an option to cancel the lease after three years
with the termination fee consisting of three months of rent. The

<b>7. Fair Value Measurements</b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The carrying amounts of cash and cash equivalents, restricted cash,
accounts payable, and accrued expenses approximated their estimated
fair values due to the short-term nature of these financial
instruments. Fair value is defined as the exchange price that would
be received for an asset or paid to transfer a liability (an exit
price) in the principal or most advantageous market for the asset
or liability in an orderly transaction between market participants
on the measurement date. Valuation techniques used to measure fair
value are performed in a manner to maximize the use of observable
inputs and minimize the use of unobservable inputs. The accounting
standard describes a fair value hierarchy based on three levels of
inputs, of which the first two are considered observable and the
last unobservable, that may be used to measure fair value, which
are the following:</p>

The short-term investments are classified as available-for-sale
securities. As of December 31, 2016, the remaining contractual
maturities of the available-for-sale securities were less than one
year, and the balance in the Company’s accumulated other
comprehensive income was comprised solely of activity related to
the Company’s available-for-sale securities. There were no
realized gains or losses recognized on the sale or maturity of
available-for-sale securities during the three years ended
December 31, 2016. As a result, the Company did not reclassify
any amounts out of accumulated other comprehensive income for the
same periods. The Company has a limited number of
available-for-sale securities in insignificant loss positions as of
December 31, 2016, which the Company does not intend to sell
and has concluded it will not be required to sell before recovery
of the amortized cost for the investment at maturity. The following

thousands):</p>

The common stock warrant liability was recorded at fair value
determined by using the Black-Scholes option-pricing model. This
method of valuation involves using inputs such as the fair value of
the Company’s common stock, stock price volatility, the
contractual term of the warrant, risk-free interest rates, and
dividend yields. Due to the nature of these inputs, the valuation
of the warrant was considered a Level 3 measurement. Upon the
closing of the IPO, the warrant was reclassified to additional
paid-in capital. See Note 5 for further discussion of the
accounting for the Bayer common stock warrant as well as for a
summary of the significant inputs and assumptions used to determine
the fair value of the warrant.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
The derivative liability related to the contingent success fee owed
under the term loans. Upon the completion of an IPO or upon the
occurrence of certain change of control or liquidation events, the
Company was required to pay a $0.2 million success fee. The Company
had recorded the success fee as a derivative financial liability.
The initial fair value of the derivative of $0.1 million had been
recorded as a debt discount. The term loans were paid in full in
October 2015; however, the liability for the success fee survived
the repayment of the term loans. Upon completion of the IPO this is
no longer accounted for as a derivative, and the success fee of
$0.2 million that is payable by June 2018 is included in other
long-term liabilities.</p>

Basic net loss attributable to common stockholders per share is
computed by dividing the net loss attributable to common
stockholders by the weighted-average number of common shares
outstanding for the period. Because the Company has reported a net
loss for the three years ended December 31, 2016, 2015, and
2014, diluted net loss per common share is the same as basic net
loss per common share for those periods. The following table

attributable to common stockholders of the Company (in thousands,

The Company has provided a valuation allowance for the full amount
of the net deferred tax assets as the realization of the deferred
tax assets is not determined to be more likely than not. The
valuation allowance increased by $13.0 million and $6.6 million in
2016 and 2015, respectively, due to the increase in deferred tax
assets, primarily due to increases in capitalized start-up and
research and development costs.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
As of December 31, 2016, the Company had approximately $36.0
million and $27.5 million in federal and state Net Operating Losses
(“NOLs”), respectively, which expire at various dates
through 2036. As of December 31, 2016, the Company had federal
and state research credits of $1.1 million and $0.9 million,
respectively, which begin to expire in 2021.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
Realization of future tax benefits is dependent on many factors,
including the Company’s ability to generate taxable income
within the net operating loss carryforward period. Under the
Internal Revenue Code provisions, certain substantial changes in
the Company’s ownership, including the sale of the Company or
significant changes in ownership due to sales of equity, have
limited and may limit in the future, the amount of net operating
loss carryforwards which could be used annually to offset future
taxable income. The Company completed an analysis through
March 8, 2016 and determined that on March 30, 2007 and
August 21, 2015, ownership changes had occurred. The Company
may also experience ownership changes in the future as a result of
subsequent shifts in our stock ownership, some of which may be
outside the Company’s control. As a result, the
Company’s ability to use our pre-change NOLs to offset U.S.
federal taxable income may be subject to limitations, which could
potentially result in increased future tax liability to the
Company. In addition, at the state level, there may be periods
during which the use of NOLs is suspended or otherwise limited,
which could accelerate or permanently increase state taxes
owed.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
As of December 31, 2016 and 2015, the Company had uncertain
tax positions of $0.2 million related to capitalized research and
development costs and research and development credits, which
reduce the deferred tax assets with a corresponding decrease to the
valuation allowance. The Company has elected to recognize interest
and penalties related to income tax matters as a component of
income tax expense, of which no interest or penalties were recorded
for the years ended December 31, 2016, 2015 and 2014. The
Company expects none of the unrecognized tax benefits to decrease
within the next 12 months related to expired statutes or settlement
with the taxing authorities. Due to the Company’s valuation
allowance as of December 31, 2016, none of the Company’s
unrecognized tax benefits, if recognized, would affect the
effective tax rate.</p>

Short-term investments include marketable securities with
maturities of less than one year or where management’s intent
is to use the investments to fund current operations or to make
them available for current operations. All investments in
marketable securities are classified as available-for-sale and are
reported at fair value with unrealized gains and losses excluded
from earnings and reported net of tax in accumulated other
comprehensive income, which is a component of stockholders’
equity (deficit). Unrealized losses that are determined to be
other-than-temporary, based on current and expected market
conditions, are recognized in earnings. Declines in fair value
determined to be credit related are charged to earnings. The cost
of marketable securities sold is determined by the specific
identification method. Investments with remaining maturities or
that are due within one year from the balance sheet date are
classified as current.</p>

Long-lived assets are reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of the
asset may not be recoverable. When such events occur, the Company
compares the carrying amounts of the assets to their undiscounted
expected future cash flows. If this comparison indicates that there
is impairment, the amount of impairment is calculated as the
difference between the carrying value and fair value. To date, no
such impairments have been recognized.</p>

<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
In November 2016, the Financial Accounting Standards Board
(“FASB”) issued Accounting Standards Update
(“ASU”) ASU 2016-18, <i>“Statement of Cash Flows
(Topic 230): Restricted Cash”</i> (“ASU
2016-18”). ASU 2016-18 requires that restricted cash and
restricted cash equivalents be included with cash and cash
equivalents when reconciling the beginning-of-period and
end-of-period total amounts shown on the statement of cash flows.
The statement of cash flows must also explain the change during the
period in the total of cash, cash equivalents, and restricted cash
or restricted cash equivalents. For public business entities,
this ASU is effective for fiscal years beginning after
December 15, 2017. The Company does not expect the adoption of
this standard to have a material impact on its consolidated
financial statements.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In March 2016, the FASB issued ASU 2016-09,
<i>Compensation—Stock Compensation (Topic 718): Improvements
to Employee Share-Based Payment Accounting</i> (“ASU
2016-09”). ASU 2016-09 simplifies several aspects related to
the accounting for share-based payment transactions, including the
accounting for income taxes, forfeitures, statutory tax withholding
requirements and classification on the statement of cash flows. ASU
2016-09 will be effective for the Company on January 1, 2017.
The Company does not expect the adoption of this standard to have a
material impact on its consolidated financial statements.</p>
<p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px">
 </p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%">
In February 2016, the FASB issued ASU 2016-02, “<i>Leases
(Topic 842)</i>.” Under ASU 2016-02, lessees will be required
to recognize, for all leases of 12 months or more, a liability to
make lease payments and a right-of-use asset representing the right
to use the underlying asset for the lease term. Additionally, the
guidance requires improved disclosures to help users of financial
statements better understand the nature of an entity’s
leasing activities. This ASU is effective for public reporting
companies for interim and annual periods beginning after
December 15, 2018, with early adoption permitted, and must be
adopted using a modified retrospective approach. The standard will
be effective for the Company on January 1, 2019. The Company
is in the process of evaluating the effect of the new guidance on
the Company’s consolidated financial statements and related
disclosures.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In August 2014, FASB issued ASU 2014-15, <i>Presentation of
Financial Statements-Going Concern</i> (“ASU 2014-15”).
ASU 2014-15 provides guidance on management’s responsibility
in evaluating whether there are conditions or events that raise
substantial doubt about a company’s ability to continue as a
going concern within one year from the date the financial
statements are issued, and about related footnote disclosures. ASU
2014-15 is effective for the annual period ending after
December 15, 2016, and for annual periods and interim periods
thereafter. The Company adopted ASU 2014-15 for the year ended
December 31, 2016, and the adoption of this standard did not
impact the Company’s consolidated financial statements and
related disclosures.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In May 2014, the FASB issued ASU 2014-09, <i>Revenue from Contracts
with Customers</i> (“ASU 2014-09”). ASU 2014-09
supersedes the revenue recognition requirements of FASB Accounting
Standards Codification (“ASC”) Topic 605, <i>Revenue
Recognition</i> and most industry-specific guidance throughout the
Accounting Standards Codification, resulting in the creation of
FASB ASC Topic 606, <i>Revenue from Contracts with Customers</i>.
ASU 2014-09 requires entities to recognize revenue in a way that
depicts the transfer of promised goods or services to customers in
an amount that reflects the consideration to which the entity
expects to be entitled to in exchange for those goods or services.
Adoption will be permitted using either a retrospective or modified
retrospective approach. In July 2015, FASB voted to delay the
effective date of the standard by one year to the first quarter of
2018 to provide companies sufficient time to implement the
standard. Early adoption will be permitted, but not before the
first quarter of 2017. The Company is currently evaluating the
method by which it will implement this standard and the impact of
the adoption of this standard on the Company’s consolidated
financial statements.</p>

<b>11. Long-Term Debt</b></p>
<p style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;">
<b><i>Solar Capital, Ltd, Term Loan</i></b></p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">
In June 2014, the Company entered into a loan and security
agreement with Solar Capital Ltd. (“Solar”), as
collateral agent and lender, consisting of a $15.0 million senior
secured term loan facility. The loan was secured by substantially
all of the Company’s existing and after-acquired assets
except its intellectual property, but including right of payment
with respect to any such intellectual property and all proceeds
from the disposition of any such intellectual property. The
intellectual property of the Company was subject to a negative
pledge. In September and December 2014, the Company amended the
term loan facility. The term loan facility had a maturity date of
June 13, 2018.</p>
<p style="font-size: 1px; margin-top: 12px; margin-bottom: 0px;">
 </p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">
In September 2014, the initial term loan (the “Term A
Loan”), in the aggregate principal amount of
$5.0 million was funded; and in December 2014, a second term
loan (the “Term C Loan”) in the aggregate principal
amount of $4.0 million was funded with the following post-closing
conditions: pursuant to the KHK License Agreement, the Company was
required to receive $7.5 million in net equity proceeds no later
than January 9, 2015 and was required to receive $17.5 million
in license-related proceeds no later than February 13, 2015,
or return the $4.0 million of proceeds from Term Loan C to Solar.
The Company achieved the post-closing conditions.</p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">
Interest accrued at a floating rate per annum equal to LIBOR plus
8.8%, payable monthly in arrears. The Company was required to make
interest-only payments on any term loans funded under the term loan
facility until July 1, 2015. Beginning on July 1, 2015,
it was required to make payments of principal plus accrued interest
in equal monthly installments until the maturity date. In addition,
the Company was required to pay a final fee equal to 4% of the
amount of term loans funded that was due on the earlier of the
maturity date of the term loan facility or upon the occurrence of
certain change of control or liquidity events. The Company accrued
the final fee of $0.4 million on the outstanding term loans through
interest expense using the effective-interest method over the
period that the debt was outstanding. The Company incurred $0.3
million of debt issuance costs for this term loan facility, which
were amortized as interest expense over the period that the related
debt was outstanding.</p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">
The Company had the option to prepay the term loans provided it
paid a prepayment fee equal to 2% of the outstanding principal if
paid prior to the one-year anniversary and 1% of the outstanding
principal if paid after the one-year anniversary of the funding. In
October 2015, the Company prepaid the outstanding balance on the
term loans of $8.3 million plus accrued interest of $0.1 million
and a final fee and prepayment penalty of $0.4 million. In
conjunction with this prepayment, the Company recorded an expense
of $0.3 million for the final fee and prepayment penalty and wrote
off $0.3 million of unamortized debt discount and deferred issuance
costs related to the term loans.</p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">
Upon the completion of an IPO or upon the occurrence of certain
change of control or liquidity events, the Company is required to
pay a $0.2 million success fee that will be due on the earlier of
the maturity date of the term loan facility or upon the occurrence
of certain change of control or liquidity events. The Company
initially recorded the success fee as a derivative financial
liability. The initial fair value of the derivative of $0.1 million
was recorded as a debt discount. The term loans were paid in full
in October 2015; however, the liability for the success fee
survived the repayment of the term loans. Upon completion of the
IPO, the success fee is no longer considered a derivative
liability. The success fee of $0.2 million is payable by June 2018
and included in other long-term liabilities.</p>

<b>1. Nature of Business</b></p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">
Syndax Pharmaceuticals, Inc. (the Company) is a clinical stage
biopharmaceutical company developing an innovative pipeline of
combination therapies in multiple cancer indications. The
Company’s lead product candidate, entinostat, is currently
being evaluated in a Phase 3 clinical trial for advanced hormone
receptor positive, human epidermal growth factor receptor 2
negative breast cancer. Entinostat was granted Breakthrough Therapy
designation by the U.S. Food and Drug Administration following
positive results from the Company’s Phase 2b clinical trial,
ENCORE 301. The Company is developing entinostat, which has direct
effects on both cancer cells and immune regulatory cells, and
SNDX-6352, a monoclonal antibody that targets the colony
stimulating factor-1 receptor to enhance the body’s immune
response on tumors that have shown sensitivity to immunotherapy.
The Company is evaluating entinostat as a combination therapeutic
in Phase 1b/2 clinical trials with Merck & Co., Inc. for
non-small cell lung cancer and melanoma; with Genentech, Inc. for
triple negative breast cancer; and with Merck KGaA, Darmstadt,
Germany, and Pfizer Inc. for ovarian cancer. We acquired the
exclusive rights to SNDX-6352 in July 2016 and are evaluating
SNDX-6352 in a single ascending dose Phase 1 clinical trial. The
Company plans to continue to leverage the technical and business
expertise of our management team and scientific collaborators to
license, acquire and develop additional cancer therapies to expand
our pipeline.</p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">
In March 2016, the Company completed its initial public offering
(“IPO”) whereby it sold 4,809,475 shares of common
stock at the initial public offering price of $12.00 per share,
which included 409,475 shares issued pursuant to the
underwriters’ partial exercise of their over-allotment option
to purchase additional shares of common stock. The aggregate net
proceeds received by the Company from the offering were $50.5
million, net of underwriting discounts and commissions of $4.0
million and offering expenses of $3.1 million. Upon the closing of
the IPO, all outstanding shares of the Company’s outstanding
convertible preferred stock converted into 12,872,551 shares of
common stock; and the Company’s outstanding warrant liability
to purchase 357,840 shares of the Company’s common stock
valued at $4.6 million was reclassified to additional paid-in
capital. The shares trade on the Nasdaq Global Select Market under
the symbol “SNDX.” In connection with the closing
of the Company’s IPO, the Company filed an amended and
restated certificate of incorporation and adopted amended and
restated bylaws, both of which were approved by the Company’s
board of directors and stockholders on September 28, 2015 and
February 24, 2016, respectively. Pursuant to the amended and
restated certificate of incorporation, the Company is now
authorized to issue 100,000,000 shares of common stock and
10,000,000 shares of preferred stock.</p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">
Since its inception, the Company has devoted its efforts
principally to research and development and raising capital. The
Company is subject to risks common to companies in the development
stage, including, but not limited to, successful development of
therapeutics, obtaining additional funding, protection of
proprietary therapeutics, compliance with government regulations,
fluctuations in operating results, dependence on key personnel and
collaborative partners, and risks associated with industry changes.
The Company’s long-term success is dependent upon its ability
to successfully develop and market its product candidates, expand
its oncology drug pipeline, earn revenue, obtain additional capital
when needed, and ultimately, achieve profitable operations. The
Company anticipates that it will be several years before either
entinostat or SNDX-6352 is approved, if ever, and the Company
begins to generate revenue from sales of entinostat and SNDX-6352.
Accordingly, management expects to incur substantial losses on the
ongoing development of entinostat and SNDX-6352 and does not expect
to achieve positive cash flow from operations for the foreseeable
future, if ever. As a result, the Company will continue to require
additional capital to move forward with its business plan. While
certain amounts of this additional capital were raised in the past,
there can be no assurance that funds necessary beyond these amounts
will be available in amounts or on terms sufficient to ensure
ongoing operations.</p>
<p style="font-size: 1px; margin-top: 12px; margin-bottom: 0px;">
 </p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">
The Company’s management believes that the cash, cash
equivalents and short-term investments balances as of
December 31, 2016 should enable the Company to maintain its
planned operations for at least the next 12 months. The
Company’s ability to fund all of its planned operations
internally beyond that date, including the completion of its
ongoing and planned clinical trial activities, may be substantially
dependent upon whether the Company can obtain sufficient funding on
terms acceptable to the Company. Proceeds from additional capital
transactions would allow the Company to accelerate and/or expand
its planned research and development activities. In the event that
sufficient funds were not available, the Company may be required to
delay or reduce expenditures to conserve cash, which could involve
scaling back or curtailing development and general and
administrative activities.</p>

<b><i>Income Taxes</i></b></p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">
The Company records deferred tax assets and liabilities for the
expected future tax consequences of temporary differences between
the Company’s financial statement carrying amounts and the
tax bases of assets and liabilities and for loss and credit
carryforwards using enacted tax rates expected to be in effect in
the years in which the differences reverse. A valuation allowance
is provided to reduce the net deferred tax assets to the amount
that will more likely than not be realized. The Company determines
whether it is more likely than not that a tax position will be
sustained upon examination. If it is not more likely than not that
a position will be sustained, none of the benefit attributable to
the position is recognized. The tax benefit to be recognized for
any tax position that meets the more-likely-than-not recognition
threshold is calculated as the largest amount that is more than 50%
likely of being realized upon resolution of the contingency. The
Company accounts for interest and penalties related to uncertain
tax positions as part of its provision for income taxes.</p>

<b><i>Use of Estimates</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The preparation of consolidated financial statements in conformity
with U.S. GAAP requires management to make estimates and
assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities
at the date of the consolidated financial statements and the
reported amounts of costs and expenses during the reporting period.
The Company bases estimates and assumptions on historical
experience when available and on various factors that it believes
to be reasonable under the circumstances. The Company evaluates its
estimates and assumptions on an ongoing basis. The Company’s
actual results may differ from these estimates under different
assumptions or conditions.</p>

<b><i>Guarantees and Indemnifications</i></b></p>
<p style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">
As permitted under Delaware law, the Company indemnifies its
officers, directors, and employees for certain events or
occurrences that happen by reason of the relationship with, or
position held at, the Company. The Company has standard
indemnification arrangements under office leases (as described in
Note 16) that require it to indemnify the landlord against all
costs, expenses, fines, suits, claims, demands, liabilities, and
actions directly resulting from any breach, violation, or
nonperformance of any covenant or condition of the Company’s
lease. Through December 31, 2016, the Company had not
experienced any losses related to these indemnification obligations
and no claims were outstanding. The Company does not expect
significant claims related to these indemnification obligations,
and consequently, concluded that the fair value of these
obligations is negligible, and no related reserves were
established.</p>

Operating segments are identified as components of an enterprise
about which separate discrete financial information is available
for evaluation by the chief operating decision maker, or decision
making group, in making decisions regarding resource allocation and
assessing performance. The Company has one operating segment.</p>
</div>
The Company has provided a valuation allowance for the full amount of the net deferred tax assets as the realization of the deferred tax assets is not determined to be more likely than not. The valuation allowance increased by $13.0 million and $6.6 million in 2016 and 2015, respectively, due to the increase in deferred tax assets, primarily due to increases in capitalized start-up and research and development costs.

Property and equipment are recorded at cost. Depreciation is
recorded using the straight-line method over the estimated useful
lives of the assets (three to five years). Assets under capital
leases are amortized over the shorter of their useful lives or
lease term using the straight-line method. Major replacements and
improvements are capitalized, while general repairs and maintenance
are expensed as incurred.</p>

<b><i>Use of Estimates</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The preparation of consolidated financial statements in conformity
with U.S. GAAP requires management to make estimates and
assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities
at the date of the consolidated financial statements and the
reported amounts of costs and expenses during the reporting period.
The Company bases estimates and assumptions on historical
experience when available and on various factors that it believes
to be reasonable under the circumstances. The Company evaluates its
estimates and assumptions on an ongoing basis. The Company’s
actual results may differ from these estimates under different
assumptions or conditions.</p>

<b><i>Cash Equivalents</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
Cash equivalents include all highly liquid investments maturing
within 90 days or less from the date of purchase. Cash equivalents
include money market funds, corporate debt securities, U.S.
government agency notes, and overnight deposits.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
<b><i>Restricted Cash</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The Company classifies as restricted cash all cash pledged as
collateral to secure long-term obligations and all cash whose use
is otherwise limited by contractual provisions. Amounts are
reported as non-current unless restrictions are expected to be
released in the next 12 months.</p>
<p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px">

<b><i>Short-Term Investments</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
Short-term investments include marketable securities with
maturities of less than one year or where management’s intent
is to use the investments to fund current operations or to make
them available for current operations. All investments in
marketable securities are classified as available-for-sale and are
reported at fair value with unrealized gains and losses excluded
from earnings and reported net of tax in accumulated other
comprehensive income, which is a component of stockholders’
equity (deficit). Unrealized losses that are determined to be
other-than-temporary, based on current and expected market
conditions, are recognized in earnings. Declines in fair value
determined to be credit related are charged to earnings. The cost
of marketable securities sold is determined by the specific
identification method. Investments with remaining maturities or
that are due within one year from the balance sheet date are
classified as current.</p>

<b><i>Segment Reporting</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
Operating segments are identified as components of an enterprise
about which separate discrete financial information is available
for evaluation by the chief operating decision maker, or decision
making group, in making decisions regarding resource allocation and
assessing performance. The Company has one operating segment.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
<b><i>Other Assets</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
Other assets consist of deferred issuance costs, long-term security
deposits, and noncurrent restricted cash. Deferred issuance costs
consist primarily of direct incremental legal and accounting fees
relating to the Company’s IPO. As of December 31, 2016
and 2015, the Company had capitalized deferred IPO issuance costs
of $0 and $1.6 million, respectively. Upon the closing of the IPO,
these costs were reclassified to additional paid-in capital as a
reduction of the IPO proceeds.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In September 2014, the Company determined that it was likely its
IPO would be postponed for a period in excess of 90 days. As a
result, in accordance with the Securities and Exchange Commission
guidance in Staff Accounting Bulletin Topic 5-A, <i>Expenses of
Offering,</i> the Company expensed as general and administrative
expenses previously deferred IPO costs of $4.3 million.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
<b><i>Concentrations of Credit Risk</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
Cash and cash equivalents, restricted cash, and short-term
investments are financial instruments that potentially subject the
Company to concentrations of credit risk. Substantially all of the
Company’s cash, cash equivalents, and short-term investments
were deposited in accounts at two financial institutions, and at
times, such deposits may exceed federally insured limits. The
Company has not experienced any losses in such accounts, and
management believes that the Company is not exposed to significant
credit risk due to the financial position of the depository
institutions in which those deposits are held. The Company’s
available-for-sale investments primarily consist of U.S. Treasury
securities, U.S. government agency securities, corporate debt
securities, certificates of deposit and overnight deposits and
potentially subject the Company to concentrations of crdit
risk.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
<b><i>Property and Equipment</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
Property and equipment are recorded at cost. Depreciation is
recorded using the straight-line method over the estimated useful
lives of the assets (three to five years). Assets under capital
leases are amortized over the shorter of their useful lives or
lease term using the straight-line method. Major replacements and
improvements are capitalized, while general repairs and maintenance
are expensed as incurred.</p>

<b><i>Impairment of Long-Lived Assets</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
Long-lived assets are reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of the
asset may not be recoverable. When such events occur, the Company
compares the carrying amounts of the assets to their undiscounted
expected future cash flows. If this comparison indicates that there
is impairment, the amount of impairment is calculated as the
difference between the carrying value and fair value. To date, no
such impairments have been recognized.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
<b><i>Revenue Recognition</i></b></p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The Company enters into license agreements for the development and
commercialization of its product candidates, entinostat and
SNDX-6352. License agreements may include non-refundable upfront
payments, contingent payments based on the occurrence of specified
events under the Company’s license arrangements, partial or
complete reimbursement of research and development expenses,
license fees and royalties on sales of entinostat if they are
successfully approved and commercialized. The Company’s
performance obligations under the license agreements may include
the transfer of intellectual property rights in the form of
licenses, obligations to provide research and development services

partners.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
Revenue is recognized when (i) persuasive evidence of an
arrangement exists, (ii) transfer of technology has been
completed, services have been performed or products have been
delivered, (iii) the fee is fixed and determinable, and
(iv) collection is reasonably assured. For revenue agreements
with multiple-elements, the Company identifies the deliverables
included within the agreement and evaluates which deliverables
represent separate units of accounting based on the achievement of
certain criteria including whether the deliverable has stand-alone
value. Upfront payments received in connection with licenses of the
Company’s technology rights are deferred if facts and
circumstances dictate that the license does not have stand-alone
value and are recognized as license revenue over the estimated
period of performance that is generally consistent with the terms
of the research and development obligations contained in the
specific license agreement.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
The Company periodically reviews its estimated periods of
performance based on the progress under each arrangement and
accounts for the impact of any changes in estimated periods of
performance on a prospective basis. At the inception of each
agreement that includes milestone payments, the Company evaluates
whether each milestone is substantive and at risk to both parties
on the basis of the contingent nature of the milestone. The Company
evaluates factors such as the scientific, regulatory, commercial
and other risks that must be overcome to achieve the respective
milestone, the level of effort and investment required to achieve
the respective milestone and whether the milestone consideration is
reasonable relative to all deliverables and payment terms in the
arrangement in making this assessment. Non-refundable payments that
are contingent upon achievement of a substantive milestone are
recognized in their entirety in the period in which the milestone
is achieved, assuming all other revenue recognition criteria are
met. Other contingent payments in which a portion of the milestone
consideration is refundable or adjusts based on future performance
or non-performance (e.g., through a penalty or claw-back provision)
are not considered to relate solely to past performance, and
therefore, not considered substantive. Amounts that are not
recognized as revenue due to the uncertainty as to whether they
will be retained or because they are expected to be refunded are
recorded as a liability. The Company recognizes non-substantive
milestone payments over the remaining estimated period of
performance once the milestone is achieved. Contingent payments
associated with the achievement of specific objectives in certain
contracts that are not considered substantive because the Company
does not contribute effort to the achievement of such milestones
are recognized as revenue upon achievement of the objective, as
long as there are no undelivered elements remaining and no
continuing performance obligations by the Company, assuming all
other revenue recognition criteria are met.</p>

the Company’s financial statement carrying amounts and the
tax bases of assets and liabilities and for loss and credit
carryforwards using enacted tax rates expected to be in effect in
the years in which the differences reverse. A valuation allowance
is provided to reduce the net deferred tax assets to the amount
that will more likely than not be realized. The Company determines
whether it is more likely than not that a tax position will be
sustained upon examination. If it is not more likely than not that
a position will be sustained, none of the benefit attributable to
the position is recognized. The tax benefit to be recognized for
any tax position that meets the more-likely-than-not recognition
threshold is calculated as the largest amount that is more than 50%
likely of being realized upon resolution of the contingency. The
Company accounts for interest and penalties related to uncertain

As permitted under Delaware law, the Company indemnifies its
officers, directors, and employees for certain events or
occurrences that happen by reason of the relationship with, or
position held at, the Company. The Company has standard
indemnification arrangements under office leases (as described in
Note 16) that require it to indemnify the landlord against all
costs, expenses, fines, suits, claims, demands, liabilities, and
actions directly resulting from any breach, violation, or
nonperformance of any covenant or condition of the Company’s
lease. Through December 31, 2016, the Company had not
experienced any losses related to these indemnification obligations
and no claims were outstanding. The Company does not expect
significant claims related to these indemnification obligations,
and consequently, concluded that the fair value of these
obligations is negligible, and no related reserves were
established.</p>

Company, as holders of the convertible preferred stock could cause
redemption of the shares in these situations. The carrying value of
the convertible preferred stock was presented at its maximum

common stock warrants are initially recorded at fair value, with
gains and losses arising from changes in fair value recognized in
other income (expense) in the consolidated statement of operations

<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
In November 2016, the Financial Accounting Standards Board
(“FASB”) issued Accounting Standards Update
(“ASU”) ASU 2016-18, <i>“Statement of Cash Flows
(Topic 230): Restricted Cash”</i> (“ASU
2016-18”). ASU 2016-18 requires that restricted cash and
restricted cash equivalents be included with cash and cash
equivalents when reconciling the beginning-of-period and
end-of-period total amounts shown on the statement of cash flows.
The statement of cash flows must also explain the change during the
period in the total of cash, cash equivalents, and restricted cash
or restricted cash equivalents. For public business entities,
this ASU is effective for fiscal years beginning after
December 15, 2017. The Company does not expect the adoption of
this standard to have a material impact on its consolidated
financial statements.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In March 2016, the FASB issued ASU 2016-09,
<i>Compensation—Stock Compensation (Topic 718): Improvements
to Employee Share-Based Payment Accounting</i> (“ASU
2016-09”). ASU 2016-09 simplifies several aspects related to
the accounting for share-based payment transactions, including the
accounting for income taxes, forfeitures, statutory tax withholding
requirements and classification on the statement of cash flows. ASU
2016-09 will be effective for the Company on January 1, 2017.
The Company does not expect the adoption of this standard to have a
material impact on its consolidated financial statements.</p>

 </p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%">
In February 2016, the FASB issued ASU 2016-02, “<i>Leases
(Topic 842)</i>.” Under ASU 2016-02, lessees will be required
to recognize, for all leases of 12 months or more, a liability to
make lease payments and a right-of-use asset representing the right
to use the underlying asset for the lease term. Additionally, the
guidance requires improved disclosures to help users of financial
statements better understand the nature of an entity’s
leasing activities. This ASU is effective for public reporting
companies for interim and annual periods beginning after
December 15, 2018, with early adoption permitted, and must be
adopted using a modified retrospective approach. The standard will
be effective for the Company on January 1, 2019. The Company
is in the process of evaluating the effect of the new guidance on
the Company’s consolidated financial statements and related
disclosures.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In August 2014, FASB issued ASU 2014-15, <i>Presentation of
Financial Statements-Going Concern</i> (“ASU 2014-15”).
ASU 2014-15 provides guidance on management’s responsibility
in evaluating whether there are conditions or events that raise
substantial doubt about a company’s ability to continue as a
going concern within one year from the date the financial
statements are issued, and about related footnote disclosures. ASU
2014-15 is effective for the annual period ending after
December 15, 2016, and for annual periods and interim periods
thereafter. The Company adopted ASU 2014-15 for the year ended
December 31, 2016, and the adoption of this standard did not
impact the Company’s consolidated financial statements and
related disclosures.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In May 2014, the FASB issued ASU 2014-09, <i>Revenue from Contracts
with Customers</i> (“ASU 2014-09”). ASU 2014-09
supersedes the revenue recognition requirements of FASB Accounting
Standards Codification (“ASC”) Topic 605, <i>Revenue
Recognition</i> and most industry-specific guidance throughout the
Accounting Standards Codification, resulting in the creation of
FASB ASC Topic 606, <i>Revenue from Contracts with Customers</i>.
ASU 2014-09 requires entities to recognize revenue in a way that
depicts the transfer of promised goods or services to customers in
an amount that reflects the consideration to which the entity
expects to be entitled to in exchange for those goods or services.
Adoption will be permitted using either a retrospective or modified
retrospective approach. In July 2015, FASB voted to delay the
effective date of the standard by one year to the first quarter of
2018 to provide companies sufficient time to implement the
standard. Early adoption will be permitted, but not before the
first quarter of 2017. The Company is currently evaluating the
method by which it will implement this standard and the impact of
the adoption of this standard on the Company’s consolidated
financial statements.</p>

The Company accounts for all stock option awards granted to
employees and non-employees using a fair value method. Stock-based
compensation is measured at the grant date fair value of employee
stock option grants and is recognized over the requisite service
period of the awards (usually the vesting period) on a
straight-line basis, net of estimated forfeitures. Stock option
awards to non-employees are subject to periodic revaluation over

<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
The Company enters into license agreements for the development and
commercialization of its product candidates, entinostat and
SNDX-6352. License agreements may include non-refundable upfront
payments, contingent payments based on the occurrence of specified
events under the Company’s license arrangements, partial or
complete reimbursement of research and development expenses,
license fees and royalties on sales of entinostat if they are
successfully approved and commercialized. The Company’s
performance obligations under the license agreements may include
the transfer of intellectual property rights in the form of
licenses, obligations to provide research and development services
and related materials and participation on certain development
and/or commercialization committees with the collaboration
partners.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
Revenue is recognized when (i) persuasive evidence of an
arrangement exists, (ii) transfer of technology has been
completed, services have been performed or products have been
delivered, (iii) the fee is fixed and determinable, and
(iv) collection is reasonably assured. For revenue agreements
with multiple-elements, the Company identifies the deliverables
included within the agreement and evaluates which deliverables
represent separate units of accounting based on the achievement of
certain criteria including whether the deliverable has stand-alone
value. Upfront payments received in connection with licenses of the
Company’s technology rights are deferred if facts and
circumstances dictate that the license does not have stand-alone
value and are recognized as license revenue over the estimated
period of performance that is generally consistent with the terms
of the research and development obligations contained in the
specific license agreement.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
The Company periodically reviews its estimated periods of
performance based on the progress under each arrangement and
accounts for the impact of any changes in estimated periods of
performance on a prospective basis. At the inception of each
agreement that includes milestone payments, the Company evaluates
whether each milestone is substantive and at risk to both parties
on the basis of the contingent nature of the milestone. The Company
evaluates factors such as the scientific, regulatory, commercial
and other risks that must be overcome to achieve the respective
milestone, the level of effort and investment required to achieve
the respective milestone and whether the milestone consideration is
reasonable relative to all deliverables and payment terms in the
arrangement in making this assessment. Non-refundable payments that
are contingent upon achievement of a substantive milestone are
recognized in their entirety in the period in which the milestone
is achieved, assuming all other revenue recognition criteria are
met. Other contingent payments in which a portion of the milestone
consideration is refundable or adjusts based on future performance
or non-performance (e.g., through a penalty or claw-back provision)
are not considered to relate solely to past performance, and
therefore, not considered substantive. Amounts that are not
recognized as revenue due to the uncertainty as to whether they
will be retained or because they are expected to be refunded are
recorded as a liability. The Company recognizes non-substantive
milestone payments over the remaining estimated period of
performance once the milestone is achieved. Contingent payments
associated with the achievement of specific objectives in certain
contracts that are not considered substantive because the Company
does not contribute effort to the achievement of such milestones
are recognized as revenue upon achievement of the objective, as
long as there are no undelivered elements remaining and no
continuing performance obligations by the Company, assuming all
other revenue recognition criteria are met.</p>

In July 2016, the Company entered into a license agreement (the
“UCB License Agreement”) with UCB Biopharma Sprl
(“UCB”), under which UCB granted to the Company a
worldwide, sublicenseable, exclusive license to UCB6352, which the
Company refers to as SNDX-6352, an IND-ready anti-CSF-1R monoclonal
antibody. The Company made a nonrefundable upfront payment of
$5.0 million to UCB in the third quarter of
2016. Additionally, subject to the achievement of certain
milestone events, the Company may be required to pay UCB up to
$119.5 million in one-time development and regulatory milestone
payments over the term of the UCB License Agreement. In the
event that the Company or any of its affiliates or sublicensees
commercializes <font style="WHITE-SPACE: nowrap">SNDX-6352,</font>
the Company will also be obligated to pay UCB low double-digit
royalties on sales, subject to reduction in certain circumstances,
as well as up to an aggregate of $250.0 million in potential
one-time, sales-based milestone payments based on achievement of
certain annual sales thresholds. Under certain circumstances,
the Company may be required to share a percentage of non-royalty
income from sublicensees, subject to certain deductions, with
UCB. The Company will be solely responsible for the
development and commercialization of SNDX-6352, except that UCB is
performing a limited set of transitional chemistry, manufacturing
and control tasks related to SNDX-6352. Each party may
terminate the UCB License Agreement for the other party’s
uncured material breach or insolvency; and the Company may
terminate the UCB License Agreement at will at any time upon
advance written notice to UCB. UCB may terminate the UCB License
Agreement if the Company or any of its affiliates or sublicensees
institutes a legal challenge to the validity, enforceability, or
patentability of the licensed patent rights. Unless terminated
earlier in accordance with its terms, the UCB License Agreement
will continue on a country-by-country and product-by-product basis
until the later of: (i) the expiration of all of the licensed
patent rights in such country; (ii) the expiration of all
regulatory exclusivity applicable to the product in such country;
and (iii) 10 years from the date of the first commercial sale
of the product in such country.</p>

As of the date of the UCB License Agreement, the asset acquired had
no alternative future use nor had it reached a stage of
technological feasibility. As the processes or activities that were
acquired along with the license do not constitute a
“business,” the transaction has been accounted for as
an asset acquisition. As a result of these findings, the
upfront payment of $5.0 million has been recorded as research and
development expense in the consolidated statements of
operations.</p>

Company entered into a license agreement (the “KHK License

exclusive license to develop and commercialize entinostat in Japan
and Korea. Under the terms of the KHK License Agreement, the
Company will be responsible for the manufacture and supply of the
products during the development activities. In addition to the
license and manufacturing obligations, the Company is obligated to
provide KHK access to know-how and regulatory information the
Company may develop over the life of the entinostat patent. Lastly,
to the extent additional intellectual property is developed during
the term of the agreement, KHK will receive the right to the
intellectual property when and if available. KHK will conduct the
development, regulatory approval filings, and commercialization
activities of entinostat in Japan and Korea. KHK paid the Company
$25.0 million upfront, which included a $7.5 million equity
investment of 536,049 shares of Series B-1 convertible preferred
stock and a $17.5 million non-refundable cash payment. In addition,
to the extent certain development and commercial milestones are
achieved, KHK will be required to pay the Company up to $75.0
million in milestone payments over the term of the license
agreement. The term of the agreement commenced on the Effective
Date and, unless earlier terminated in accordance with the terms of
the agreement, will continue on a country-by-country and

The purchase of the Series B-1 and the up-front payment of the
license fee were accounted for separately. The Company allocated
the amount of consideration related to Series B-1 equal to the fair
value of the Series B-1 shares on the Effective Date based on a
share price of $14.39 per share, which resulted in $7.7 million of
proceeds allocated to the Series B-1 and the remaining
consideration of $17.3 million allocated to the up-front license
fee. The fair value of the Series B-1 of $14.39 per share was based
on a contemporaneous valuation. The Company received $7.5 million
and issued the Series B-1 in January 2015 and received the
remaining $17.5 million in February 2015. On the date of
issuance, the Company recorded accretion of $5.4 million to record
the Series B-1 at its redemption value.</p>

The Company has concluded that this agreement is within the scope
of ASC 605-25, <i>Revenue Recognition, Multiple-Element
Arrangements</i>. Pursuant to this guidance, the Company identified
the following deliverables: (i) licenses, (ii) clinical
supply and manufacturing obligations, (iii) rights to access
and use materials and data, and (iv) rights to additional
intellectual property. All other potential deliverables included in
the arrangement have been deemed either contingent or
inconsequential or perfunctory, individually and in the aggregate.
Moreover, the Company has evaluated all deliverables included in
the KHK License Agreement and determined that there are two units
of accounting in connection with its obligations at inception under
the KHK License Agreement: (i) license unit of accounting and
(ii) rights to additional intellectual property. The first
three deliverables identified above comprise the license unit of
accounting. The Company concluded that the stand-alone selling
price for the rights to additional intellectual property unit of
account is immaterial. As such, the entire $17.3 million allocated
to the upfront payment was allocated to the license unit of
accounting.</p>

The arrangement consideration allocated to the license unit of
accounting will be recognized as revenue ratably over the
Company’s expected services period (currently expected to be
through 2029) commencing on the date of the first delivery of the
clinical trial materials. In June 2015, the Company began
delivering clinical materials to KHK and commenced recognizing
revenue from the upfront consideration of $17.3 million. During the
years ended December 31, 2016 and 2015, the Company recognized
$1.2 million and $0.6 million, respectively, of revenue associated
with the KHK License Agreement. As of December 31, 2016, there
was $15.4 million of deferred revenue related to the KHK
License Agreement, which is classified as current or <font style="WHITE-SPACE: nowrap">long-term</font> in the consolidated balance
sheets.</p>

In March 2014, the Company entered into the “ECOG Agreement
with Eastern Cooperative Oncology Group, a contracting entity for
the Eastern Cooperative Oncology Group—American College of
Radiology Imaging Network Cancer Research Group
(“ECOG-ACRIN”), that describes the parties’
obligations with respect to the NCI-sponsored pivotal Phase 3
clinical trial of entinostat. Under the terms of the ECOG
Agreement, ECOG-ACRIN will perform this clinical trial in
accordance with the clinical trial protocol and a mutually agreed
scope of work. The Company will provide a fixed level of financial
support for the clinical trial through an upfront payment of
$695,000 and a series of payments of up to $1.0 million each
that are comprised of milestone payments through the completion of
enrollment and time-based payments through the completion of
patient monitoring post-enrollment. In addition, the Company is
obligated to supply entinostat and placebo to <font style="WHITE-SPACE: nowrap">ECOG-ACRIN</font> for use in the clinical
trial. During the second quarter of 2016, the ECOG Agreement was
amended to provide additional study activities and the contractual
obligation increased by $0.8 million. As of December 31, 2016,
the Company’s aggregate payment obligations under this
agreement were approximately $21.4 million; and as of
December 31, 2016, the Company’s remaining payment
obligations are approximately $12.9 million over an estimated
period of approximately four years. During the first quarter of
2017, the ECOG Agreement was amended to expand the study to include
enrollments from sites in Korea and the contractual obligation
increased by $0.5 million.</p>

Data and inventions from the Phase 3 clinical trial are owned by
ECOG-ACRIN. The Company has access to the data generated in the
clinical trial, both directly from ECOG-ACRIN under the ECOG
Agreement as well as from the NCI. Additionally, ECOG-ACRIN has
granted the Company a non-exclusive royalty-free license to any
inventions or discoveries that are derived from entinostat as a
result of its use during the clinical trial, along with a first
right to negotiate an exclusive license to any of these inventions
or discoveries. Either party may terminate the ECOG Agreement in
the event of an uncured material breach by the other party or if
the FDA or NCI withdraws the authorization to perform the clinical
trial in the United States. The parties may jointly terminate the
ECOG Agreement if the parties agree that safety-related issues
support termination of the clinical trial.</p>

The Company records the appropriate clinical trial expenses in its
financial statements by matching those expenses with the period in
which the services and efforts are expended. The Company accounts
for these expenses according to the progress of the clinical trial
as measured by patient enrollment and the timing of various aspects
of the clinical trial. The Company determines accrual estimates
through financial models, taking into account discussion with
applicable personnel and ECOG-ACRIN as to the progress or state of
consummation of the clinical trial or the services completed.</p>

In March 2007, the Company entered into a license agreement (the
“Bayer Agreement”) with Bayer Schering Pharma AG
(“Bayer”) for a worldwide, exclusive license to develop
and commercialize entinostat and any other products containing the
same active ingredient. Under the terms of the Bayer Agreement, the
Company paid a nonrefundable up-front license fee of $2.0 million
and is responsible for the development and marketing of entinostat.
The Company recorded the $2.0 million license fee as research and
development expense during the year ended December 31, 2007,
as it had no alternative future use. The Company will pay Bayer
royalties on a sliding scale based on net sales, if any, and make
future milestone payments to Bayer of up to $150.0 million in the
event that certain specified development and regulatory goals and
sales levels are achieved. In June 2014, a development milestone
was achieved, and the Company recorded $2.0 million of research and
development expense, which has been fully paid.</p>
<p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
In connection with the Bayer Agreement, the Company issued to Bayer
a warrant to purchase the number of shares of the Company’s
common stock equal to 1.75% of the shares of common stock
outstanding on a fully diluted basis as of the earlier of the date
the warrant is exercised or the closing of the IPO. Upon the
closing of the IPO, the total number of shares of the
Company’s common stock issuable upon exercise of the warrant
was set at 357,840. Prior to the closing of the IPO, the warrant
contained anti-dilution protection to maintain Bayer’s
potential ownership at 1.75% of the shares of common stock
outstanding on a fully diluted basis, which requires that the
actual number of shares of common stock issuable pursuant to the
warrant be increased or decreased for any changes in the fully
diluted shares of common stock outstanding. The warrant is
exercisable at an exercise price of $1.54 per share and expires
upon the earlier of the 10-year anniversary of the closing of the
IPO or the date of the consummation of a disposition transaction.
The warrant was classified as a long-term liability and recorded at
fair value with the changes in the fair value recorded in other
expense. The Company used the Black-Scholes option-pricing model to
determine the fair value of the warrant. Upon the closing of the
IPO, the anti-dilution protection for the warrant expired,
resulting in the reclassification of the warrant liability to
additional paid-in capital. The warrant was re-measured on
March 8, 2016, using current assumptions just prior to the
reclassification.</p>
