 The Company leases its office space and obtains certain

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company has a master license agreement, dated May&amp;#xA0;19,
 2006, with the University of Maryland, Baltimore
 (&amp;#x201C;UMB&amp;#x201D;), as amended by First Amendment, dated as of
 March&amp;#xA0;3, 2009, Second Amendment, dated as of April&amp;#xA0;10,
 2012, and Third Amendment, dated as of October&amp;#xA0;28, 2013 (the
 &amp;#x201C;license agreement&amp;#x201D;). Pursuant to the license
 agreement, UMB granted an exclusive worldwide license, with the
 right to sublicense, under certain patents and patent applications
 to make, have made, use, sell, offer to sell and import certain
 anti-androgen steroids including galeterone for the prevention,
 diagnosis, treatment or control of any human or animal disease. In
 addition, UMB granted the Company a first option to receive an
 exclusive license to UMB&amp;#x2019;s rights in certain improvements to
 the licensed products. The Company has exercised the option and
 acquired exclusive rights to licensed improvements under three
 amendments to the license agreement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company is obligated to pay UMB an annual maintenance fee of
 $10 each year until the first commercial sale of a product
 developed using the licensed technology. The Company is also
 obligated to make an additional $50 milestone payment to UMB for
 each additional investigational new drug application filed for a
 licensed product and a $100 milestone payment upon the approval of
 each new drug application for a licensed product by the U.S. Food
 and Drug Administration. Because the achievement of these
 milestones has not occurred as of December&amp;#xA0;31, 2013 or
 September&amp;#xA0;30, 2014, no liabilities for such milestone payments
 have been recorded in the Company&amp;#x2019;s consolidated financial
 statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company must also pay UMB low-single-digit percentage royalties
 on aggregate worldwide net sales of licensed products, including
 sales by sublicensees, on a licensed product-by-licensed product
 and country-by-country basis until the later of the expiration of
 the last-to-expire applicable licensed patent or ten years after
 first commercial sale of the applicable licensed product, in each
 case in the applicable country. The royalty obligations are subject
 to specified reductions in the event that additional licenses need
 to be obtained from third parties or in the event of specified
 competition from third-party products licensed by UMB. Minimum
 annual royalty payments to UMB are $50 beginning in the year
 following the year in which the first commercial sale occurs. The
 Company must also pay UMB 10% of all non-royalty sublicense income
 received from sublicensees. Finally, the Company is responsible for
 all patent expenses related to the prosecution and maintenance of
 the licensed patents. As of December&amp;#xA0;31, 2013 and
 September&amp;#xA0;30, 2014, the Company has not yet developed a
 commercial product using the licensed technologies, and it has not
 entered into any sublicense agreements for the technologies. In
 connection with this license agreement, the Company incurred no
 license, milestone or maintenance fees for the three months ended
 September&amp;#xA0;30, 2014 or 2013. In connection with this license
 agreement, the Company incurred license, milestone and maintenance
 fees of $10 in each of the nine month periods ended
 September&amp;#xA0;30, 2014 and 2013.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Advisor Agreement&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company was obligated to pay a fee to a financial advisor of
 $1,053 upon the closing of the IPO of the Company&amp;#x2019;s shares of
 common stock in connection with strategic and financial advisory
 services unrelated to the IPO. As of September&amp;#xA0;30, 2014, the
 Company had recorded general and administrative expense of $1,053
 related to this payment.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Indemnification Agreements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In the ordinary course of business, the Company may provide
 indemnification of varying scope and terms to vendors, lessors,
 business partners, and other parties with respect to certain
 matters including, but not limited to, losses arising out of breach
 of such agreements or from intellectual property infringement
 claims made by third parties.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"&gt;
 In addition, the Company has entered into indemnification
 agreements with each of its directors and executive officers, which
 provide, among other things, that the Company will indemnify such
 directors and executive officers to the fullest extent permitted by
 law for claims arising in his or her capacity as a director or
 officer. The maximum potential amount of future payments the
 Company could be required to make under these indemnification
 agreements is, in many cases, unlimited&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 To date, the Company has not incurred any material costs as a
 result of the indemnification agreements described above. The
 Company does not believe that the outcome of any claims under
 indemnification arrangements will have a material effect on its
 financial position, results of operations or cash flows, and it has
 not accrued any liabilities related to such obligations in its
 financial statements as of December&amp;#xA0;31, 2013 or
 September&amp;#xA0;30, 2014.&lt;/p&gt;

 In September 2014, upon the closing of the IPO, all of the
 outstanding shares of the Company&amp;#x2019;s redeemable convertible
 preferred stock automatically converted into 14,860,173 shares of
 the Company&amp;#x2019;s common stock. Prior to this conversion, the
 Company followed the two-class method when computing net income
 (loss) per share as the Company had issued shares that met the
 definition of participating securities. The two-class method
 determines net income (loss) per share for each class of common and
 participating securities according to dividends declared or
 accumulated and participation rights in undistributed earnings. The
 two-class method requires income available to common stockholders
 for the period to be allocated between common and participating
 securities based upon their respective rights to receive dividends
 as if all income for the period had been distributed. The
 Company&amp;#x2019;s redeemable convertible preferred stock
 contractually entitled the holders of such shares to participate in
 dividends, but did not contractually require the holders of such
 shares to participate in losses of the Company. Accordingly, the
 two-class method did not apply for periods in which the Company
 reported a net loss or a net loss attributable to common
 stockholders resulting from dividends or accretion related to its
 redeemable convertible preferred stock.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 Basic net income (loss) per share attributable to common
 stockholders is computed by dividing the net income (loss)
 attributable to common stockholders by the weighted average number
 of common shares outstanding for the period. Diluted net income
 (loss) per share attributable to common stockholders is computed by
 dividing the diluted net income (loss) attributable to common
 stockholders by the weighted average number of common shares,
 including potential dilutive common shares assuming the dilutive
 effect of outstanding stock options and unvested restricted common
 shares, as determined using the treasury stock method. For periods
 in which the Company has reported net losses, diluted net loss per
 common share attributable to common stockholders is the same as
 basic net loss per common share attributable to common
 stockholders, since dilutive common shares are not assumed to have
 been issued if their effect is anti-dilutive.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company reported a net loss attributable to common stockholders
 for the three and nine months ended September&amp;#xA0;30, 2014 and
 2013.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The following common stock equivalents outstanding as of
 September&amp;#xA0;30, 2014 and 2013 were excluded from the computation
 of diluted net loss per share for the three and nine months ended
 September&amp;#xA0;30, 2014 and 2013, because they had an anti-dilutive
 impact:&lt;/p&gt;

 The Company accounts for income taxes using the asset and liability
 method, which requires the recognition of deferred tax assets and
 liabilities for the expected future tax consequences of events that
 have been recognized in the consolidated financial statements or in
 the Company&amp;#x2019;s tax returns. Deferred taxes are determined
 based on the difference between the financial statement and tax
 basis of assets and liabilities using enacted tax rates in effect
 in the years in which the differences are expected to reverse.
 Changes in deferred tax assets and liabilities are recorded in the
 provision for income taxes. The Company assesses the likelihood
 that its deferred tax assets will be recovered from future taxable
 income and, to the extent it believes, based upon the weight of
 available evidence, that it is more likely than not that all or a
 portion of deferred tax assets will not be realized, a valuation
 allowance is established through a charge to income tax expense.
 Potential for recovery of deferred tax assets is evaluated by
 estimating the future taxable profits expected and considering
 prudent and feasible tax planning strategies.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company accounts for uncertainty in income taxes recognized in
 the consolidated financial statements by applying a two-step
 process to determine the amount of tax benefit to be recognized.
 First, the tax position must be evaluated to determine the
 likelihood that it will be sustained upon external examination by
 the taxing authorities. If the tax position is deemed
 more-likely-than-not to be sustained, the tax position is then
 assessed to determine the amount of benefit to recognize in the
 consolidated financial statements. The amount of the benefit that
 may be recognized is the largest amount that has a greater than 50%
 likelihood of being realized upon ultimate settlement. The
 provision for income taxes includes the effects of any resulting
 tax reserves, or unrecognized tax benefits, that are considered
 appropriate as well as the related net interest and penalties.&lt;/p&gt;

 The preparation of financial statements in conformity with GAAP
 requires management to make estimates and assumptions that affect
 the reported amounts of assets and liabilities, the disclosure of
 contingent assets and liabilities at the date of the consolidated
 financial statements, and the reported amounts of expenses during
 the reporting periods. Significant estimates and assumptions
 reflected in these consolidated financial statements include, but
 are not limited to, the accrual of research and development
 expenses and the valuation of common stock, redeemable convertible
 preferred stock and stock-based awards. Estimates are periodically
 reviewed in light of changes in circumstances, facts and
 experience. Actual results could differ from the Company&amp;#x2019;s
 estimates.&lt;/p&gt;

 Property and equipment are stated at cost less accumulated
 depreciation. Depreciation expense is recognized using the
 straight-line method over a three-year estimated useful life for
 computer equipment, which is the only type of property and

 maintenance of assets are charged to expense as incurred. Upon
 retirement or sale, the cost and related accumulated depreciation
 of assets disposed of are removed from the accounts and any
 resulting gain or loss is included in loss from operations.&lt;/p&gt;

 Research and development costs are expensed as incurred. Included
 in research and development expenses are salaries, stock-based
 compensation and benefits of employees, third-party license fees
 and other operational costs related to the Company&amp;#x2019;s research
 and development activities, including manufacturing expenses and
 external costs of outside vendors engaged to conduct both
 preclinical studies and clinical trials.&lt;/p&gt;

 The Company has entered into various research and development
 contracts with research institutions and other companies both
 inside and outside of the United States. These agreements are
 generally cancelable, and related payments are recorded as research
 and development expenses as incurred. The Company records accruals
 for estimated ongoing costs. This process involves reviewing open
 contracts and purchase orders, communicating with personnel to
 identify services that have been performed and estimating the level
 of service performed and the associated costs incurred for the
 services for which the Company has not yet been invoiced.
 Significant judgments and estimates are made in determining the
 accrued balances at the end of any reporting period. Actual results
 could differ from the Company&amp;#x2019;s estimates. The
 Company&amp;#x2019;s historical accrual estimates have not been
 materially different from the actual costs.&lt;/p&gt;

 On August&amp;#xA0;29, 2014, the Company effected a 1-for-10.47 reverse
 stock split of its issued and outstanding shares of common stock
 and a proportional adjustment to the existing conversion ratios for
 each series of redeemable convertible preferred stock. Accordingly,
 all share and per share amounts for all periods presented in these
 consolidated financial statements and notes thereto have been
 adjusted retroactively, where applicable, to reflect this reverse
 stock split and adjustment of the redeemable convertible preferred
 stock conversion ratios.&lt;/p&gt;

 Tokai Pharmaceuticals, Inc. (the &amp;#x201C;Company&amp;#x201D;) was
 incorporated on March&amp;#xA0;26, 2004 under the laws of the State of
 Delaware. The Company is a clinical-stage biopharmaceutical company
 focused on developing novel proprietary therapies for the treatment
 of prostate cancer and other hormonally-driven diseases. The
 Company&amp;#x2019;s lead drug candidate, galeterone, is a highly
 selective, multi-targeted, oral small molecule drug candidate.
 Since its inception, the Company has devoted substantially all of
 its efforts to research and development, recruiting management,
 in-licensing technology and raising capital.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company was previously classified as a &amp;#x201C;development stage
 entity&amp;#x201D; in the Accounting Standards Codification and, as
 such, was required to present inception-to-date information in the
 Company&amp;#x2019;s statements of operations and comprehensive loss,
 redeemable convertible preferred stock and stockholders&amp;#x2019;
 deficit, and cash flows. In June 2014, the Financial Accounting
 Standards Board (&amp;#x201C;FASB&amp;#x201D;) issued an accounting standards
 update that eliminates the concept of a development stage entity
 from U.S. generally accepted accounting principles and removes the
 related incremental reporting requirements. See Note 2 below for
 additional information on this new standard. The Company elected to
 early adopt the new standard in the three months ended
 September&amp;#xA0;30, 2014. Accordingly, in contrast to the
 Company&amp;#x2019;s financial statements and the notes thereto for the
 year ended December&amp;#xA0;31, 2013 included in Company&amp;#x2019;s
 Registration Statement on Form S-1 on file with the Securities and
 Exchange Commission (&amp;#x201C;SEC&amp;#x201D;), the financial statements
 contained in this report do not include inception-to-date
 information.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company is subject to risks common to companies in the
 biotechnology industry including, but not limited to, new
 technological innovations, protection of proprietary technology,
 dependence on key personnel, compliance with government regulations
 and the need to obtain additional financing. Galeterone, which is
 currently under development, and any product candidates that the
 Company may seek to develop in the future will require significant
 additional research and development efforts, including extensive
 preclinical and clinical testing and regulatory approval, prior to
 commercialization. These efforts require significant amounts of
 additional capital, adequate personnel infrastructure, and
 extensive compliance-reporting capabilities.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 There can be no assurance that the Company&amp;#x2019;s research and
 development will be successfully completed, that adequate
 protection for the Company&amp;#x2019;s intellectual property will be
 obtained, that any products developed will obtain necessary
 government regulatory approval or that any approved products will
 be commercially viable. Even if the Company&amp;#x2019;s drug
 development efforts are successful, it is uncertain when, if ever,
 the Company will generate significant revenue from product sales.
 The Company operates in an environment of rapid change in
 technology and substantial competition from pharmaceutical and
 biotechnology companies. In addition, the Company is dependent upon
 the services of its employees and consultants.&lt;/p&gt;

 include Diotima Pharmaceuticals, Inc. (&amp;#x201C;Diotima&amp;#x201D;), a
 variable interest entity in which the Company had a variable
 financial interest and was the primary beneficiary but had no
 ownership interest. In 2010, the Company formed and incorporated
 Diotima. Diotima operated as a stand-alone company with limited
 activity through April 2014. In early 2014, the license agreements
 relating to the Diotima compounds were terminated. Additionally, in
 April 2014, the board of directors and stockholders of Diotima
 approved the dissolution of Diotima, and Diotima was dissolved.
 Expenses incurred by Diotima for the three and nine months ended
 September&amp;#xA0;30, 2014 were $0 and $8, respectively, and for the
 three and nine months ended September&amp;#xA0;30, 2013, were $1 and
 $59, respectively. All significant intercompany balances and
 transactions between the Company and Diotima have been eliminated
 in consolidation.&lt;/p&gt;

 On September&amp;#xA0;22, 2014, the Company completed an initial public
 offering (&amp;#x201C;IPO&amp;#x201D;) of its common stock, and issued and
 sold 6,480,000 shares of common stock at a public offering price of
 $15.00 per share, resulting in net proceeds of approximately
 $90,396 after deducting underwriting discounts and commissions but
 before the payment of estimated offering expenses of $3,306. Upon
 the closing of the IPO, all outstanding shares of the
 Company&amp;#x2019;s redeemable convertible preferred stock
 automatically converted into 14,860,173 shares of the
 Company&amp;#x2019;s common stock. On October&amp;#xA0;9, 2014, the Company
 issued and sold an additional 540,000 shares of its common stock at
 the IPO price of $15.00 per share, less underwriting discounts and
 commissions, pursuant to the underwriters&amp;#x2019; partial exercise
 of their option to purchase additional shares of common stock,
 resulting in additional net proceeds to the Company of
 approximately $7,533 after deducting underwriting discounts and
 commissions (Note 10).&lt;/p&gt;

 The consolidated balance sheet at December&amp;#xA0;31, 2013 was
 derived from audited financial statements, but does not include all
 disclosures required by U.S. generally accepted accounting
 principles (&amp;#x201C;GAAP&amp;#x201D;). The accompanying unaudited
 consolidated financial statements as of September&amp;#xA0;30, 2014 and
 for the three months and nine months ended September&amp;#xA0;30, 2014
 and 2013 have been prepared by the Company, pursuant to the rules
 and regulations of the SEC for interim financial statements.
 Certain information and footnote disclosures normally included in
 financial statements prepared in accordance with GAAP have been
 condensed or omitted pursuant to such rules and regulations.
 However, the Company believes that the disclosures are adequate to
 make the information presented not misleading. These consolidated
 financial statements should be read in conjunction with the
 Company&amp;#x2019;s audited consolidated financial statements and the
 notes thereto for the year ended December&amp;#xA0;31, 2013 included in
 the Company&amp;#x2019;s Registration Statement on Form S-1, File Number
 333-198052 on file with the SEC. In the opinion of management, all
 adjustments, consisting only of normal recurring adjustments
 necessary for a fair statement of the Company&amp;#x2019;s financial
 position as of September&amp;#xA0;30, 2014 and consolidated results of
 operations for the three and nine months ended September&amp;#xA0;30,
 2014 and 2013 and cash flows for the nine months ended
 September&amp;#xA0;30, 2014 and 2013 have been made. The results of
 operations for the three and nine months ended September&amp;#xA0;30,
 2014 are not necessarily indicative of the results of operations
 that may be expected for the year ending December&amp;#xA0;31,
 2014.&lt;/p&gt;

 The Company capitalizes certain legal, accounting and other
 third-party fees that are directly associated with in-process
 equity financings as other assets until such financings are
 consummated. After consummation of the equity financing, these
 costs are recorded in stockholders&amp;#x2019; equity (deficit) as a
 reduction of additional paid-in capital generated as a result of
 the offering or as a reduction to the carrying value of preferred
 stock issued. As of December&amp;#xA0;31, 2013, the Company had
 recorded $30 of deferred offering costs, included in other assets
 in the accompanying consolidated balance sheet in contemplation of
 the Company&amp;#x2019;s IPO, which closed in September 2014. The
 Company has no deferred offering costs as of September&amp;#xA0;30,
 2014.&lt;/p&gt;

 The Company did not provide for any income taxes in any of the
 three or nine month periods ended September&amp;#xA0;30, 2014 or 2013.
 The Company had gross deferred tax assets of $24,402 at
 December&amp;#xA0;31, 2013 which increased by approximately $6,800 at
 September&amp;#xA0;30, 2014. The Company has provided a valuation
 allowance for the full amount of its net deferred tax assets
 because, at September&amp;#xA0;30, 2014 and December&amp;#xA0;31, 2013, it
 was more likely than not that any future benefit from deductible
 temporary differences and net operating loss and tax credit
 carryforwards would not be realized.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company has not recorded any amounts for unrecognized tax
 benefits as of September&amp;#xA0;30, 2014 or December&amp;#xA0;31, 2013.
 As of September&amp;#xA0;30, 2014 and December&amp;#xA0;31, 2013, the
 Company had no accrued interest or tax penalties recorded. The
 Company&amp;#x2019;s income tax return reporting periods since
 December&amp;#xA0;31, 2011 are open to income tax audit examination by
 the federal and state tax authorities. In addition, because the
 Company has net operating loss carryforwards, the Internal Revenue
 Service is permitted to audit earlier years and propose adjustments
 up to the amount of net operating losses generated in those
 years.&lt;/p&gt;

 The preparation of financial statements in conformity with GAAP
 requires management to make estimates and assumptions that affect
 the reported amounts of assets and liabilities, the disclosure of
 contingent assets and liabilities at the date of the consolidated
 financial statements, and the reported amounts of expenses during
 the reporting periods. Significant estimates and assumptions
 reflected in these consolidated financial statements include, but
 are not limited to, the accrual of research and development
 expenses and the valuation of common stock, redeemable convertible
 preferred stock and stock-based awards. Estimates are periodically
 reviewed in light of changes in circumstances, facts and
 experience. Actual results could differ from the Company&amp;#x2019;s
 estimates.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 62px; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;&lt;i&gt;Cash Equivalents&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company considers all short-term, highly liquid investments
 with original maturities of ninety days or less at date of purchase
 to be cash equivalents. Cash equivalents, which consist of money
 market accounts, are stated at fair value.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 62px; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;&lt;i&gt;Concentration of Credit Risk and of Significant
 Suppliers&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

 Financial instruments that potentially expose the Company to
 concentrations of credit risk consist primarily of cash and cash
 equivalents. The Company has all cash and cash equivalents balances
 at one accredited financial institution, in amounts that exceed
 federally insured limits. The Company does not believe that it is
 subject to unusual credit risk beyond the normal credit risk
 associated with commercial banking relationships.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company is dependent on third-party manufacturers to supply
 products for research and development activities in its programs.
 In particular, the Company relies and expects to continue to rely
 on a small number of manufacturers to supply it with its
 requirements for the active pharmaceutical ingredients and
 formulated drugs related to these programs. These programs could be
 adversely affected by a significant interruption in the supply of
 active pharmaceutical ingredients and formulated drugs.&lt;/p&gt;

 Certain assets and liabilities are carried at fair value under
 GAAP. 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 must maximize the use of observable inputs and minimize the
 use of unobservable inputs. Financial assets and liabilities
 carried at fair value are to be classified and disclosed in one of
 the following three levels of the fair value hierarchy, of which
 the first two are considered observable and the last is considered
 unobservable:&lt;/p&gt;

 The Company&amp;#x2019;s cash equivalents of $91,311 and $1,311 as of
 September&amp;#xA0;30, 2014 and December&amp;#xA0;31, 2013, respectively,
 were carried at fair value based on Level 2 inputs. The carrying

 in the accompanying consolidated balance sheet in contemplation of
 the Company&amp;#x2019;s IPO, which closed in September 2014. The
 Company has no deferred offering costs as of September&amp;#xA0;30,

 &lt;b&gt;&lt;i&gt;Property and Equipment&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

 Property and equipment are stated at cost less accumulated
 depreciation. Depreciation expense is recognized using the
 straight-line method over a three-year estimated useful life for
 computer equipment, which is the only type of property and
 equipment the Company holds. Expenditures for repairs and
 maintenance of assets are charged to expense as incurred. Upon
 retirement or sale, the cost and related accumulated depreciation
 of assets disposed of are removed from the accounts and any
 resulting gain or loss is included in loss from operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 62px; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;&lt;i&gt;Impairment of Long-Lived Assets&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 Long-lived assets consist of property and equipment. Long-lived
 assets to be held and used are tested for recoverability whenever
 events or changes in business circumstances indicate that the
 carrying amount of the assets may not be fully recoverable. Factors
 that the Company considers in deciding when to perform an
 impairment review include significant underperformance of the
 business in relation to expectations, significant negative industry
 or economic trends, and significant changes or planned changes in
 the use of the assets. If an impairment review is performed to
 evaluate a long-lived asset for recoverability, the Company
 compares forecasts of undiscounted cash flows expected to result
 from the use and eventual disposition of the long-lived asset to
 its carrying value. An impairment loss would be recognized when
 estimated undiscounted future cash flows expected to result from
 the use of an asset are less than its carrying amount. The
 impairment loss would be based on the excess of the carrying value
 of the impaired asset over its fair value, determined based on
 discounted cash flows. To date, the Company has not recorded any
 impairment losses on long-lived assets.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 62px; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 Research and development costs are expensed as incurred. Included
 in research and development expenses are salaries, stock-based
 compensation and benefits of employees, third-party license fees
 and other operational costs related to the Company&amp;#x2019;s research
 and development activities, including manufacturing expenses and
 external costs of outside vendors engaged to conduct both
 preclinical studies and clinical trials.&lt;/p&gt;

 The Company has entered into various research and development
 contracts with research institutions and other companies both
 inside and outside of the United States. These agreements are
 generally cancelable, and related payments are recorded as research
 and development expenses as incurred. The Company records accruals
 for estimated ongoing costs. This process involves reviewing open
 contracts and purchase orders, communicating with personnel to
 identify services that have been performed and estimating the level
 of service performed and the associated costs incurred for the
 services for which the Company has not yet been invoiced.
 Significant judgments and estimates are made in determining the
 accrued balances at the end of any reporting period. Actual results
 could differ from the Company&amp;#x2019;s estimates. The
 Company&amp;#x2019;s historical accrual estimates have not been
 materially different from the actual costs.&lt;/p&gt;

 The Company measures all stock options and other stock-based awards
 granted to employees and directors at the fair value on the date of
 the grant using the Black-Scholes option-pricing model. The fair
 value of the awards is recognized as expense, net of estimated
 forfeitures, over the requisite service period, which is generally
 the vesting period of the respective award. The straight-line
 method of expense recognition is applied to all awards with
 service-only conditions, while the graded vesting method is applied
 to all grants with both service and performance conditions.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 For stock-based awards granted to non-employees, compensation
 expense is recognized over the period during which services are
 rendered by such non-employees until completed. At the end of each
 financial reporting period prior to completion of the service, the
 fair value of these awards is remeasured using the then-current
 fair value of the Company&amp;#x2019;s common stock and updated
 assumption inputs in the Black-Scholes option-pricing model.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company classifies stock-based compensation expense in its
 consolidated statement of operations and comprehensive loss in the
 same manner in which the award recipient&amp;#x2019;s payroll costs are
 classified or in which the award recipient&amp;#x2019;s service payments
 are classified.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company recognizes compensation expense for only the portion of
 awards that are expected to vest. In developing a forfeiture rate
 estimate, the Company has considered its historical experience to
 estimate pre-vesting forfeitures for service-based awards. The
 impact of a forfeiture rate adjustment will be recognized in full
 in the period of adjustment, and if the actual forfeiture rate is
 materially different from the Company&amp;#x2019;s estimate, the Company
 may be required to record adjustments to stock-based compensation
 expense in future periods.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Income Taxes&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company accounts for income taxes using the asset and liability
 method, which requires the recognition of deferred tax assets and
 liabilities for the expected future tax consequences of events that
 have been recognized in the consolidated financial statements or in
 the Company&amp;#x2019;s tax returns. Deferred taxes are determined
 based on the difference between the financial statement and tax
 basis of assets and liabilities using enacted tax rates in effect
 in the years in which the differences are expected to reverse.
 Changes in deferred tax assets and liabilities are recorded in the
 provision for income taxes. The Company assesses the likelihood
 that its deferred tax assets will be recovered from future taxable
 income and, to the extent it believes, based upon the weight of
 available evidence, that it is more likely than not that all or a
 portion of deferred tax assets will not be realized, a valuation
 allowance is established through a charge to income tax expense.
 Potential for recovery of deferred tax assets is evaluated by
 estimating the future taxable profits expected and considering
 prudent and feasible tax planning strategies.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company accounts for uncertainty in income taxes recognized in
 the consolidated financial statements by applying a two-step
 process to determine the amount of tax benefit to be recognized.
 First, the tax position must be evaluated to determine the
 likelihood that it will be sustained upon external examination by
 the taxing authorities. If the tax position is deemed
 more-likely-than-not to be sustained, the tax position is then
 assessed to determine the amount of benefit to recognize in the
 consolidated financial statements. The amount of the benefit that
 may be recognized is the largest amount that has a greater than 50%
 likelihood of being realized upon ultimate settlement. The
 provision for income taxes includes the effects of any resulting
 tax reserves, or unrecognized tax benefits, that are considered
 appropriate as well as the related net interest and penalties.&lt;/p&gt;

 The Company manages its operations as a single segment for the
 purposes of assessing performance and making operating decisions.
 The Company&amp;#x2019;s singular focus is on developing novel
 proprietary therapies for the treatment of prostate cancer and
 other hormonally-driven diseases. No revenue has been generated
 since inception, and all tangible assets are held in the United
 States.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 62px; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 Comprehensive loss includes net loss as well as other changes in
 stockholders&amp;#x2019; equity (deficit) that result from transactions
 and economic events other than those with stockholders. For the
 three and nine months ended September&amp;#xA0;30, 2014 and 2013, there
 was no difference between net loss and comprehensive loss.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-LEFT: 62px; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 In September 2014, upon the closing of the IPO, all of the
 outstanding shares of the Company&amp;#x2019;s redeemable convertible
 preferred stock automatically converted into 14,860,173 shares of
 the Company&amp;#x2019;s common stock. Prior to this conversion, the
 Company followed the two-class method when computing net income
 (loss) per share as the Company had issued shares that met the
 definition of participating securities. The two-class method
 determines net income (loss) per share for each class of common and
 participating securities according to dividends declared or
 accumulated and participation rights in undistributed earnings. The
 two-class method requires income available to common stockholders
 for the period to be allocated between common and participating
 securities based upon their respective rights to receive dividends
 as if all income for the period had been distributed. The
 Company&amp;#x2019;s redeemable convertible preferred stock
 contractually entitled the holders of such shares to participate in
 dividends, but did not contractually require the holders of such
 shares to participate in losses of the Company. Accordingly, the
 two-class method did not apply for periods in which the Company
 reported a net loss or a net loss attributable to common
 stockholders resulting from dividends or accretion related to its
 redeemable convertible preferred stock.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 Basic net income (loss) per share attributable to common
 stockholders is computed by dividing the net income (loss)
 attributable to common stockholders by the weighted average number
 of common shares outstanding for the period. Diluted net income
 (loss) per share attributable to common stockholders is computed by
 dividing the diluted net income (loss) attributable to common
 stockholders by the weighted average number of common shares,
 including potential dilutive common shares assuming the dilutive
 effect of outstanding stock options and unvested restricted common
 shares, as determined using the treasury stock method. For periods
 in which the Company has reported net losses, diluted net loss per
 common share attributable to common stockholders is the same as
 basic net loss per common share attributable to common
 stockholders, since dilutive common shares are not assumed to have
 been issued if their effect is anti-dilutive.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The Company reported a net loss attributable to common stockholders
 for the three and nine months ended September&amp;#xA0;30, 2014 and
 2013.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 The following common stock equivalents outstanding as of
 September&amp;#xA0;30, 2014 and 2013 were excluded from the computation
 of diluted net loss per share for the three and nine months ended
 September&amp;#xA0;30, 2014 and 2013, because they had an anti-dilutive
 impact:&lt;/p&gt;

 In June 2014, the FASB issued Accounting Standards Update
 No.&amp;#xA0;2014-10,&amp;#xA0;&lt;i&gt;Development Stage Entities
 (Topic 915): Elimination of Certain Financial Reporting
 Requirements, Including an Amendment to Variable Interest Entities
 Guidance in Topic 810, Consolidation&lt;/i&gt;. The amendments in this
 guidance remove all incremental financial reporting requirements
 for development stage entities.&amp;#xA0;Among other changes, this
 guidance will no longer require development stage entities to
 present inception-to-date information about income statement line
 items, cash flows, and equity transactions. This guidance is
 effective for public companies in the first annual period beginning
 after December&amp;#xA0;15, 2014 with early adoption
 permitted.&amp;#xA0;The Company elected to apply this disclosure
 guidance to its financial statements for the three months ended
 September&amp;#xA0;30, 2014 and as a result, no longer discloses
 inception-to-date information in its statements of operations and
 comprehensive loss, cash flows and stockholders&amp;#x2019; deficit and
 the related notes thereto.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"&gt;
 In August 2014, the FASB issued ASU 2014-15,&amp;#xA0;&lt;i&gt;Presentation of Financial
 Statements &amp;#x2014; Going Concern&lt;/i&gt;&amp;#xA0;(&lt;i&gt;Subtopic
 205-40).&lt;/i&gt;&amp;#xA0;The
 new guidance addresses management&amp;#x2019;s responsibility to
 evaluate whether there is substantial doubt about an entity&amp;#x2019;s
 ability to continue as a going concern and to provide related
 footnote disclosures. Management&amp;#x2019;s evaluation should be based
 on relevant conditions and events that are known and reasonably
 knowable at the date that the financial statements are issued. The
 standard will be effective for the first interim period within
 annual reporting periods beginning after December&amp;#xA0;15, 2016.
 Early adoption is permitted. The Company is evaluating the effect
 that this guidance will have on its consolidated financial
 statements.&lt;/p&gt;

 In connection with the IPO, on October&amp;#xA0;9, 2014, the Company
 issued and sold an additional 540,000 shares of its common stock at
 the IPO price of $15.00 per share, less underwriting discounts and
 commissions, pursuant to the underwriters&amp;#x2019; partial exercise
 of their option to purchase additional shares of common stock,
 resulting in additional net proceeds to the Company of
 approximately $7,533 after deducting underwriting discounts and

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Under the Company&amp;#x2019;s 2007 Stock Incentive Plan, as amended
 (the &amp;#x201C;2007 Plan&amp;#x201D;), the Company was authorized to grant
 options, restricted stock, restricted stock units and other
 stock-based awards to the Company&amp;#x2019;s employees, officers,
 directors, consultants and advisors. As of December&amp;#xA0;31, 2013,
 a total of 1,590,580 shares of common stock were reserved for
 issuance under the 2007 Plan. The Company&amp;#x2019;s 2014 Stock
 Incentive Plan (the &amp;#x201C;2014 Plan&amp;#x201D;) became effective upon
 effectiveness of the registration statement for the IPO on
 September&amp;#xA0;12, 2014. Upon the effectiveness of the 2014 Plan,
 43,923 shares of common stock that remained available for grant
 under the 2007 Plan became available for grant under the 2014 Plan,
 and no further awards were available to be issued under the 2007
 Plan.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;

 In August 2014, the Company&amp;#x2019;s board of directors and
 stockholders approved the 2014 Plan, which became effective upon
 effectiveness of the registration statement for the IPO on
 September&amp;#xA0;12, 2014. Under the 2014 Plan, the Company may grant
 incentive stock options, nonstatutory stock options, restricted
 stock, restricted stock units, stock appreciation rights and other
 stock-based awards to the Company&amp;#x2019;s employees, officers,
 directors, consultants and advisors; however, incentive stock
 options may only be granted to the Company&amp;#x2019;s employees. The
 number of shares reserved for issuance under the 2014 Plan is equal
 to the sum of (1)&amp;#xA0;1,700,000 shares of common stock, plus
 (2)&amp;#xA0;the number of shares (up to 1,678,220 shares) equal to the
 sum of (i)&amp;#xA0;43,923 shares of common stock, which is the number
 of shares reserved for issuance under the 2007 Plan that remained
 available for grant under the 2007 Plan immediately prior to the
 effectiveness of the 2014 Plan, and (ii)&amp;#xA0;the number of shares
 of common stock subject to outstanding awards under the 2007 Plan
 that expire, terminate or are otherwise surrendered, cancelled,
 forfeited or repurchased by the Company at their original issuance
 price pursuant to a contractual repurchase right, plus (3)&amp;#xA0;an
 annual increase, to be added on the first day of each fiscal year,
 beginning with the fiscal year ending December&amp;#xA0;31, 2015 and
 continuing for each fiscal year until, and including, the fiscal
 year ending December&amp;#xA0;31, 2024, equal to the least of 1,800,000
 shares of the Company&amp;#x2019;s common stock, 4% of the number of
 shares of the Company&amp;#x2019;s common stock outstanding on the first
 day of the applicable fiscal year and an amount determined by the
 Company&amp;#x2019;s board of directors.&lt;/p&gt;

 As required by the 2007 Plan and 2014 Plan, the exercise price for
 stock options granted is not to be less than the fair value of
 common stock as of the date of grant. Prior to the IPO, the value
 of common stock was determined by the Company&amp;#x2019;s board of
 directors by taking into consideration its most recently available
 valuation of common stock performed by management and the board of
 directors as well as additional factors which might have changed
 since the date of the most recent contemporaneous valuation through
 the date of grant.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 For the three months ended September&amp;#xA0;30, 2014, the Company
 granted an employee a stock option to purchase 218,417 shares of
 its common stock and a restricted stock unit for 54,604 shares of
 common stock. The Company did not grant any other equity awards
 during the three months ended September&amp;#xA0;30, 2014. As of
 September&amp;#xA0;30, 2014, 1,470,902 shares remained available for
 issuance under the 2014 Plan.&lt;/p&gt;

 In August 2014, the Company&amp;#x2019;s board of directors and
 stockholders approved the 2014 Employee Stock Purchase Plan (the
 &amp;#x201C;ESPP&amp;#x201D;), which became effective upon effectiveness of
 the registration statement for the IPO on September&amp;#xA0;12, 2014.
 An aggregate of 225,000 shares of the Company&amp;#x2019;s common stock
 are reserved for issuance under the ESPP. The number of shares of
 the Company&amp;#x2019;s common stock reserved for issuance under the
 ESPP will automatically increase on the first day of each fiscal
 year, commencing on January&amp;#xA0;1, 2015 and ending on
 December&amp;#xA0;31, 2024, in an amount equal to the least of
 (1)&amp;#xA0;450,000 shares of the Company&amp;#x2019;s common stock,
 (2)&amp;#xA0;1% of the total number of shares of the Company&amp;#x2019;s
 common stock outstanding on the first day of the applicable fiscal
 year and (3)&amp;#xA0;an amount determined by the Company&amp;#x2019;s board
 of directors.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Stock Option Valuation&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The fair value of each stock option grant is estimated on the date
 of grant using the Black-Scholes option-pricing model. Prior to its
 IPO, the Company was a private company and lacked company-specific
 historical and implied volatility information. Therefore, the
 Company estimated its expected stock volatility based on the
 historical volatility of a publicly traded group of peer companies.
 The Company expects to continue to do so until such time as it has
 adequate historical data regarding the volatility of its own traded
 stock price. The expected term of the Company&amp;#x2019;s stock options
 has been determined utilizing the &amp;#x201C;simplified&amp;#x201D; method
 for awards that qualify as &amp;#x201C;plain-vanilla&amp;#x201D; options. The
 expected term of stock options granted to non-employees is equal to
 the contractual term of the option award. The risk-free interest
 rate is determined by reference to the U.S.&amp;#xA0;Treasury yield
 curve in effect at the time of grant of the award for time periods
 approximately equal to the expected term of the award. Expected
 dividend yield is based on the fact that the Company has never paid
 cash dividends and does not expect to pay any cash dividends in the
 foreseeable future.&lt;/p&gt;

 Long-lived assets consist of property and equipment. Long-lived
 assets to be held and used are tested for recoverability whenever
 events or changes in business circumstances indicate that the
 carrying amount of the assets may not be fully recoverable. Factors
 that the Company considers in deciding when to perform an
 impairment review include significant underperformance of the
 business in relation to expectations, significant negative industry
 or economic trends, and significant changes or planned changes in
 the use of the assets. If an impairment review is performed to
 evaluate a long-lived asset for recoverability, the Company
 compares forecasts of undiscounted cash flows expected to result
 from the use and eventual disposition of the long-lived asset to
 its carrying value. An impairment loss would be recognized when
 estimated undiscounted future cash flows expected to result from
 the use of an asset are less than its carrying amount. The
 impairment loss would be based on the excess of the carrying value
 of the impaired asset over its fair value, determined based on
 discounted cash flows. To date, the Company has not recorded any
 impairment losses on long-lived assets.&lt;/p&gt;

 In June 2014, the FASB issued Accounting Standards Update
 No.&amp;#xA0;2014-10, &lt;i&gt;Development Stage Entities (Topic 915):
 Elimination of Certain Financial Reporting Requirements, Including
 an Amendment to Variable Interest Entities Guidance in Topic 810,
 Consolidation&lt;/i&gt;. The amendments in this guidance remove all
 incremental financial reporting requirements for development stage
 entities.&amp;#xA0;Among other changes, this guidance will no longer
 require development stage entities to present inception-to-date
 information about income statement line items, cash flows, and
 equity transactions. This guidance is effective for public
 companies in the first annual period beginning after
 December&amp;#xA0;15, 2014 with early adoption permitted.&amp;#xA0;The
 Company elected to apply this disclosure guidance to its financial
 statements for the three months ended September&amp;#xA0;30, 2014 and
 as a result, no longer discloses inception-to-date information in
 its statements of operations and comprehensive loss, cash flows and
 stockholders&amp;#x2019; deficit and the related notes thereto.&lt;/p&gt;

 Financial Statements &amp;#x2014; Going Concern&lt;/i&gt; (&lt;i&gt;Subtopic
 205-40).&lt;/i&gt; The new guidance addresses management&amp;#x2019;s
 responsibility to evaluate whether there is substantial doubt about
 an entity&amp;#x2019;s ability to continue as a going concern and to
 provide related footnote disclosures. Management&amp;#x2019;s evaluation
 should be based on relevant conditions and events that are known
 and reasonably knowable at the date that the financial statements
 are issued. The standard will be effective for the first interim
 period within annual reporting periods beginning after
 December&amp;#xA0;15, 2016. Early adoption is permitted. The Company is
 evaluating the effect that this guidance will have on its
 consolidated financial statements.&lt;/p&gt;

 Certain assets and liabilities are carried at fair value under
 GAAP. 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 must maximize the use of observable inputs and minimize the
 use of unobservable inputs. Financial assets and liabilities
 carried at fair value are to be classified and disclosed in one of
 the following three levels of the fair value hierarchy, of which
 the first two are considered observable and the last is considered
 unobservable:&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company measures all stock options and other stock-based awards
 granted to employees and directors at the fair value on the date of
 the grant using the Black-Scholes option-pricing model. The fair
 value of the awards is recognized as expense, net of estimated
 forfeitures, over the requisite service period, which is generally
 the vesting period of the respective award. The straight-line
 method of expense recognition is applied to all awards with
 service-only conditions, while the graded vesting method is applied
 to all grants with both service and performance conditions.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 For stock-based awards granted to non-employees, compensation
 expense is recognized over the period during which services are
 rendered by such non-employees until completed. At the end of each
 financial reporting period prior to completion of the service, the
 fair value of these awards is remeasured using the then-current
 fair value of the Company&amp;#x2019;s common stock and updated
 assumption inputs in the Black-Scholes option-pricing model.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company classifies stock-based compensation expense in its
 consolidated statement of operations and comprehensive loss in the
 same manner in which the award recipient&amp;#x2019;s payroll costs are
 classified or in which the award recipient&amp;#x2019;s service payments
 are classified.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company recognizes compensation expense for only the portion of
 awards that are expected to vest. In developing a forfeiture rate
 estimate, the Company has considered its historical experience to
 estimate pre-vesting forfeitures for service-based awards. The
 impact of a forfeiture rate adjustment will be recognized in full
 in the period of adjustment, and if the actual forfeiture rate is
 materially different from the Company&amp;#x2019;s estimate, the Company
 may be required to record adjustments to stock-based compensation
 expense in future periods.&lt;/p&gt;
