 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;The Bristol-Myers Squibb License Agreement&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 On May&amp;#xA0;31, 2005, the Company entered into a worldwide,
 exclusive License Agreement with Bristol-Myers Squibb Company
 (&amp;#x201C;BMS&amp;#x201D;), pursuant to which the Company holds a license
 to certain patents and know-how of BMS relating to ITI-007 and
 other specified compounds. The agreement was amended on
 November&amp;#xA0;3, 2010. The licensed rights are exclusive, except
 BMS retains rights in specified compounds in the fields of obesity,
 diabetes, metabolic syndrome and cardiovascular disease. However,
 BMS has no right to use, develop or commercialize ITI-007 and other
 specified compounds in any field of use. The Company has the right
 to grant sublicenses of the rights conveyed by BMS. The Company is
 obliged under the license to use commercially reasonable efforts to
 develop and commercialize the licensed technology. The Company is
 also prohibited from engaging in the clinical development or
 commercialization of specified competitive compounds.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 Under the agreement, the Company made an upfront payment of $1.0
 million to BMS, a milestone payment of $1.25 million in December
 2013, and a milestone payment of $1.5 million in December 2014
 following the initiation of the Company&amp;#x2019;s first Phase 3
 clinical trial for ITI-007 for patients with exacerbated
 schizophrenia. Possible milestone payments remaining total $12.0
 million. Under the agreement, the Company may be obliged to make
 other milestone payments to BMS for each licensed product of up to
 an aggregate of approximately $14.75 million. The Company is also
 obliged to make tiered single digit percentage royalty payments on
 sales of licensed products. The Company is obliged to pay to BMS a
 percentage of non-royalty payments made in consideration of any
 sublicense.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 The agreement extends, and royalties are payable, on a
 country-by-country and product-by-product basis, through the later
 of ten years after first commercial sale of a licensed product in
 such country, expiration of the last licensed patent covering a
 licensed product, its method of manufacture or use, or the
 expiration of other government grants providing market exclusivity,
 subject to certain rights of the parties to terminate the agreement
 on the occurrence of certain events. On termination of the
 agreement, the Company may be obliged to convey to BMS rights in
 developments relating to a licensed compound or licensed product,
 including regulatory filings, research results and other
 intellectual property rights.&lt;/p&gt;
 &lt;p style="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;The Takeda Pharmaceutical License and Collaboration Agreement
 and Termination Agreement&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 On February&amp;#xA0;25, 2011, the Company entered into a license and
 collaboration agreement (the &amp;#x201C;Takeda License
 Agreement&amp;#x201D;) with Takeda Pharmaceutical Company Limited
 (&amp;#x201C;Takeda&amp;#x201D;) under which the Company agreed to
 collaborate to research, develop and commercialize its proprietary
 compound ITI-214 and other selected compounds that selectively
 inhibit PDE1 for use in the prevention and treatment of human
 diseases. As part of the agreement, the Company assigned to Takeda
 certain patents owned by the Company that claim ITI-214 and granted
 Takeda an exclusive license to develop and commercialize compounds
 identified in the conduct of the research program that satisfy
 specified criteria. However, the Company retained rights to all
 compounds that do not meet the specified criteria and the Company
 continues to develop PDE1 inhibitors outside the scope of the
 agreement.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 On October&amp;#xA0;31, 2014, the Company entered into an agreement
 with Takeda terminating the Takeda License Agreement, pursuant to
 which all rights granted under the Takeda License Agreement were
 returned to the Company. Takeda will complete certain ongoing
 activities relating to non-clinical studies and will transfer
 product inventory and materials to the Company but will not have
 any other ongoing involvement or funding obligations in connection
 with the development program. ITI-214 is the first compound in its
 class to successfully advance into Phase 1 clinical trials. The
 Company intends to continue the development of ITI-214 for the
 treatment of CNS and other disorders. The Company is in the process
 of refining its strategy for the PDE1 inhibitor program. By
 regaining unrestricted access to ITI-214, backups and the
 proprietary chemistry, the Company can now integrate the efforts of
 its internal PDE program to include the later stage portfolio. The
 Company does not anticipate a significant increase in its operating
 expenses related to its PDE development programs during 2015. Other
 compounds in the PDE portfolio are also being advanced for the
 treatment of various indications, including non-CNS therapeutic
 areas.&lt;/p&gt;
 &lt;p style="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;Other License Agreement&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 In May&amp;#xA0;2002, the Company entered into a license agreement (the
 &amp;#x201C;License&amp;#x201D;) and research agreement with a university.
 Under the provisions of the License, the Company is entitled to use
 this organization&amp;#x2019;s patented technology and other
 intellectual property relating to diagnosis and treatment of
 central nervous system disorders.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 The License expires upon expiration of the patent rights or 15
 years subsequent to the first sale of products developed through
 this License. ITI is required to make future milestone payments for
 initiation of clinical trials and approval of a New Drug
 Application (&amp;#x201C;NDA&amp;#x201D;). Should ITI commercialize the
 technology related to this License, ITI would be required to make
 royalty payments, and would also be required to pay fees under any
 sublicense agreements with third parties.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 In addition, ITI is required to use at least $1.0&amp;#xA0;million
 annually of its resources for the development and commercialization
 of the technology until ITI submits an NDA. ITI met its spending
 requirements in 2014. There were no other payments made or required
 for the three months ended March&amp;#xA0;31, 2015 and 2014.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 Basic net loss per common share is determined by dividing the net
 loss allocable to common stockholders by the weighted-average
 number of common shares outstanding during the period, without
 consideration of common stock equivalents. Diluted net loss per
 share is computed by dividing the net loss allocable to common
 stockholders by the weighted-average number of common stock
 equivalents outstanding for the period. The treasury stock method
 is used to determine the dilutive effect of the Company&amp;#x2019;s
 stock option grants.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The&amp;#xA0;following common stock equivalents were excluded in the
 calculation of diluted loss per share because their effect would be
 anti-dilutive as applied to the loss from operations for the three

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 All components of comprehensive income (loss), including net income
 (loss), are reported in the financial statements in the period in
 which they are incurred. Comprehensive income (loss) is defined as
 the change in equity of a business enterprise during a period from
 transactions and other events and circumstances from non-owner
 sources. In accordance with accounting guidance, the Company
 presents the impact of any unrealized gains or (losses) on its
 investment securities in a separate statement of comprehensive
 income (loss) for each period.&lt;/p&gt;
 &lt;/div&gt;</us-gaap:ComprehensiveIncomePolicyPolicyTextBlock>

 &lt;b&gt;Income Taxes&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 Income taxes are accounted for using the liability method. Deferred
 tax assets and liabilities are recognized for the future tax
 consequences attributable to differences between the financial
 statement carrying amounts of existing assets and liabilities and
 its respective tax bases. Deferred tax assets and liabilities are
 measured using enacted tax rates expected to apply to taxable
 income in the year in which those temporary differences are
 expected to be recovered or settled.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The effect on deferred tax assets and liabilities of a change in
 tax rates is recognized in income in the period that includes the
 enactment date. Valuation allowances are established when necessary
 to reduce net deferred tax assets to the amount expected to be
 realized. Income tax expense is the tax payable for the period and
 the change during the period in deferred tax assets and
 liabilities.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The Company accounts for uncertain tax positions pursuant to ASC
 Topic 740 (previously included in FASB Interpretation No.&amp;#xA0;48,
 &lt;i&gt;Accounting for Uncertainty in Income Taxes&amp;#x2013;an
 Interpretation of FASB Statement No.&amp;#xA0;109)&lt;/i&gt;. Financial
 statement recognition of a tax position taken or expected to be
 taken in a tax return is determined based on a more-likely-than-not
 threshold of that position being sustained. If the tax position
 meets this threshold, the benefit to be recognized is measured as
 the tax benefit having the highest likelihood of being realized
 upon ultimate settlement with the taxing authority. The Company
 recognizes interest accrued related to unrecognized tax benefits
 and penalties in the provision for income taxes.&lt;/p&gt;

 The Company has classified all of its investment securities
 available-for-sale, including those with maturities beyond one
 year, as current assets on the consolidated balance sheets based on
 the highly liquid nature of the investment securities and because
 these investment securities are considered available for use in
 current operations. As of March&amp;#xA0;31, 2015 and December&amp;#xA0;31,
 2014, the Company held $36.5 million and $31.8 million,
 respectively, of available-for-sale investment securities with
 contractual maturity dates more than one year and less than two
 years.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 Accounts receivable that management has the intent and ability to
 collect are reported in the balance sheets at outstanding amounts,
 less an allowance for doubtful accounts. The Company writes off
 uncollectible receivables when the likelihood of collection is
 remote.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The Company evaluates the collectability of accounts receivable on
 a regular basis. The allowance, if any, is based upon various
 factors including the financial condition and payment history of
 customers, an overall review of collections experience on other
 accounts and economic factors or events expected to affect future
 collections experience. No allowance was recorded as of
 March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2014, as the Company has
 a history of collecting on all of its accounts, including
 government agencies and collaborations funding its research.&lt;/p&gt;

 &lt;b&gt;Revenue Recognition&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 Revenue is recognized when all terms and conditions of the
 agreements have been met, including that persuasive evidence of an
 arrangement exists, delivery has occurred or services have been
 rendered, the price is fixed or determinable and collectability is
 reasonably assured. The Company is reimbursed for certain costs
 incurred on specified research projects under the terms and
 conditions of grants, collaboration agreements, and awards. The
 Company records the amount of reimbursement as revenues on a gross
 basis in accordance with ASC Topic 605-45, &lt;i&gt;Revenue
 Recognition/Principal Agent Considerations&lt;/i&gt;. The Company is the
 primary obligor with respect to purchasing goods and services from
 third-party suppliers, is obligated to compensate the service
 provider for the work performed, and has discretion in selecting
 the supplier. Provisions for estimated losses on research grant
 projects and any other contracts are made in the period such losses
 are determined.&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 entered into arrangements involving the delivery of
 more than one element. Each required deliverable is evaluated to
 determine whether it qualifies as a separate unit of accounting.
 For the Company, this determination is generally based on whether
 the deliverable has &amp;#x201C;stand-alone value&amp;#x201D; to the
 customer. The Company adopted this accounting standard on a
 prospective basis for all Multiple-Deliverable Revenue Arrangements
 (&amp;#x201C;MDRAs&amp;#x201D;), entered into on or after January&amp;#xA0;1,
 2011, and for any MDRAs that were entered into prior to
 January&amp;#xA0;1, 2011, but materially modified on or after that
 date.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The adoption of this accounting standard did not have a material
 impact on the Company&amp;#x2019;s results of operations for the
 quarters ended March&amp;#xA0;31, 2015 and 2014, or on the
 Company&amp;#x2019;s financial positions as of March&amp;#xA0;31, 2015 and
 December&amp;#xA0;31, 2014.&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 adopted ASC Topic 605-28, &lt;i&gt;Milestone Method&lt;/i&gt;.
 Under this guidance, the Company recognizes revenue contingent upon
 the achievement of a substantive milestone in its entirety in the
 period the milestone is achieved. Substantive milestone payments
 are recognized upon achievement of the milestone only if all of the
 following conditions are met:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 6pt; MARGIN-TOP: 0pt"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; BORDER-COLLAPSE: collapse" cellspacing="0" cellpadding="0" width="100%" border="0"&gt;
 &lt;tr&gt;
 &lt;td width="5%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" width="2%" align="left"&gt;&amp;#x2022;&lt;/td&gt;
 &lt;td valign="top" width="1%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" align="left"&gt;the milestone payments are
 non-refundable;&lt;/td&gt;
 &lt;/tr&gt;
 &lt;/table&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 6pt; MARGIN-TOP: 0pt"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; BORDER-COLLAPSE: collapse" cellspacing="0" cellpadding="0" width="100%" border="0"&gt;
 &lt;tr&gt;
 &lt;td width="5%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" width="2%" align="left"&gt;&amp;#x2022;&lt;/td&gt;
 &lt;td valign="top" width="1%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" align="left"&gt;achievement of the milestone involves
 a degree of risk and was not reasonably assured at the inception of
 the arrangement;&lt;/td&gt;
 &lt;/tr&gt;
 &lt;/table&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 6pt; MARGIN-TOP: 0pt"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; BORDER-COLLAPSE: collapse" cellspacing="0" cellpadding="0" width="100%" border="0"&gt;
 &lt;tr&gt;
 &lt;td width="5%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" width="2%" align="left"&gt;&amp;#x2022;&lt;/td&gt;
 &lt;td valign="top" width="1%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" align="left"&gt;substantive effort on our part is
 involved in achieving the milestone;&lt;/td&gt;
 &lt;/tr&gt;
 &lt;/table&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 6pt; MARGIN-TOP: 0pt"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; BORDER-COLLAPSE: collapse" cellspacing="0" cellpadding="0" width="100%" border="0"&gt;
 &lt;tr&gt;
 &lt;td width="5%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" width="2%" align="left"&gt;&amp;#x2022;&lt;/td&gt;
 &lt;td valign="top" width="1%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" align="left"&gt;the amount of the milestone payment
 is reasonable in relation to the effort expended or the risk
 associated with achievement of the milestone; and&lt;/td&gt;
 &lt;/tr&gt;
 &lt;/table&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 6pt; MARGIN-TOP: 0pt"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; BORDER-COLLAPSE: collapse" cellspacing="0" cellpadding="0" width="100%" border="0"&gt;
 &lt;tr&gt;
 &lt;td width="5%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" width="2%" align="left"&gt;&amp;#x2022;&lt;/td&gt;
 &lt;td valign="top" width="1%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" align="left"&gt;a reasonable amount of time passes
 between the up-front license payment and the first milestone
 payment, as well as between each subsequent milestone payment.&lt;/td&gt;
 &lt;/tr&gt;
 &lt;/table&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Determination as to whether a payment meets the aforementioned
 conditions involves management&amp;#x2019;s judgment. If any of these
 conditions are not met, the resulting payment would not be
 considered a substantive milestone, and therefore, the resulting
 payment would be considered part of the consideration for the
 single unit of accounting and be recognized as revenue as such
 performance obligations are performed under either the proportional
 performance or straight-line methods, as applicable. In addition,
 the determination that one such payment was not a substantive
 milestone could prevent the Company from concluding that subsequent
 milestone payments were substantive milestones and, as a result,
 any additional milestone payments could also be considered part of
 the consideration for the single unit of accounting and would be
 recognized as revenue as such performance obligations are performed
 under either the proportional performance or straight-line methods,
 as applicable.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 The preparation of financial statements in conformity with
 generally accepted accounting principles requires management to
 make estimates and assumptions that affect the amounts reported in
 the financial statements and accompanying notes. Although actual
 results could differ from those estimates, management does not
 believe that such differences would be material.&lt;/p&gt;

 The Company considers all highly liquid investments with a maturity
 of three months or less from the date of purchase to be cash
 equivalents. Cash and cash equivalents consist of checking
 accounts, money market accounts, money market funds, and
 certificates of deposit with a maturity date of three months or
 less. Certificates of deposit, commercial paper, corporate notes
 and corporate bonds with a maturity date of more than three months
 are classified separately on the balance sheet. Their carrying
 values approximate the fair market value.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 Property and equipment is stated at cost and depreciated on a
 straight-line basis over estimated useful lives ranging from three
 to five years. Leasehold improvements are amortized using the
 straight-line method over the shorter of the estimated useful life
 of the assets or the term of the related lease. Expenditures for
 maintenance and repairs are charged to operations as incurred.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 When indicators of possible impairment are identified, the Company
 evaluates the recoverability of the carrying value of its
 long-lived assets based on the criteria established in ASC
 Topic&amp;#xA0;360, &lt;i&gt;Property, Plant and Equipment&lt;/i&gt;. The Company
 considers historical performance and anticipated future results in
 its evaluation of potential impairment. The Company evaluates the
 carrying value of those assets in relation to the operating
 performance of the business and undiscounted cash flows expected to
 result from the use of those assets. Impairment losses are
 recognized when carrying value exceeds the undiscounted cash flows,
 in which case management must determine the fair value of the
 underlying asset. No such impairment losses have been recognized to
 date.&lt;/p&gt;

 Except for payments made in advance of services, the Company
 expenses its research and development costs as incurred. For
 payments made in advance, the Company recognizes research and
 development expense as the services are rendered. Research and
 development costs primarily consist of salaries and related
 expenses for personnel and resources and the costs of clinical
 trials. Other research and development expenses include
 pre-clinical analytical testing, outside services, providers,
 materials and consulting fees.&lt;/p&gt;

 (&amp;#x201C;ITI&amp;#x201D;), is a biopharmaceutical company focused on the
 discovery and clinical development of innovative, small molecule
 drugs that address underserved medical needs in neuropsychiatric
 and neurological disorders by targeting intracellular signaling
 mechanisms within the central nervous system (&amp;#x201C;CNS&amp;#x201D;).
 The Company&amp;#x2019;s lead product candidate, ITI-007, is in Phase 3
 clinical development as a first-in-class treatment for
 schizophrenia.&lt;/p&gt;

 ITI was incorporated in the State of Delaware on May&amp;#xA0;22, 2001
 under the name &amp;#x201C;Intra-Cellular Therapies, Inc.&amp;#x201D; and
 commenced operations in June&amp;#xA0;2002. ITI was founded to discover
 and develop drugs for the treatment of neurological and psychiatric
 disorders.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 On August&amp;#xA0;29, 2013, ITI completed a reverse merger (the
 &amp;#x201C;Merger&amp;#x201D;) with a public shell company named Oneida
 Resources Corp. (&amp;#x201C;Oneida&amp;#x201D;). Oneida was formed in August
 2012 as a vehicle to investigate and, if such investigation
 warranted, acquire a target company or business seeking the
 perceived advantages of being a publicly held corporation. In the
 Merger, each outstanding share of capital stock of ITI was
 exchanged for 0.5 shares of common stock of Oneida, and each
 outstanding option to purchase one share of ITI common stock and
 each outstanding warrant to purchase one share of ITI common stock
 was assumed by Oneida and became exercisable for 0.5 shares of
 Oneida common stock. As a result of the Merger and related
 transactions, ITI survived as a wholly-owned subsidiary of Oneida,
 Oneida changed its fiscal year end from March&amp;#xA0;31 to
 December&amp;#xA0;31, and Oneida changed its name to Intra-Cellular
 Therapies, Inc. (the &amp;#x201C;Company&amp;#x201D;). In addition, the
 Company began operating ITI and its business, and therefore ceased
 being a shell company. Following the Merger and the redemption of
 all then outstanding shares of Oneida at the closing of the Merger,
 the former shareholders of ITI owned 100% of the shares of the
 Company&amp;#x2019;s outstanding capital 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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 In accordance with Financial Accounting Standards Board
 (&amp;#x201C;FASB&amp;#x201D;), Accounting Standards Codification
 (&amp;#x201C;ASC&amp;#x201D;) Topic 805,&amp;#xA0;&lt;i&gt;Business Combinations&lt;/i&gt;,
 ITI was considered the acquirer for accounting purposes, and had
 accounted for the transaction as a capital transaction, because
 ITI&amp;#x2019;s former stockholders received 100% of the voting rights
 in the combined entity and ITI&amp;#x2019;s senior management
 represented all of the senior management of the combined entity.
 Consequently, the assets and liabilities and the historical
 operations that are reflected in the Company&amp;#x2019;s consolidated
 financial statements are those of ITI and have been recorded at the
 historical cost basis of the Company. All share and per share
 amounts in the condensed consolidated financial statements and
 related notes have been retrospectively adjusted to reflect the
 one-for-0.5 shares of capital stock exchange as well as the
 conversion of the Notes (defined below) and the Series A, B, and C
 redeemable convertible preferred stock of ITI.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Immediately prior to the Merger, on August&amp;#xA0;29, 2013, ITI sold
 to accredited investors approximately $60.0 million of its shares
 of common stock, or 18,889,307 shares at a price of $3.1764 per
 share (the &amp;#x201C;Private Placement&amp;#x201D;), which included $15.3
 million in principal and $0.8 million in accrued interest from the
 conversion of ITI&amp;#x2019;s then outstanding convertible promissory
 notes (the &amp;#x201C;Notes&amp;#x201D;).&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 On February&amp;#xA0;5, 2014, the Company completed a public offering
 of common stock in which the Company sold 7,063,300 shares of
 common stock, which included the exercise of the
 underwriters&amp;#x2019; option to purchase an additional 921,300
 shares, at an offering price of $17.50 per share. After deducting
 underwriting discounts, commissions and offering expenses, the net
 proceeds to the Company were approximately $115.4 million.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 On October&amp;#xA0;31, 2014, the Company entered into a termination
 agreement with Takeda Pharmaceutical Company Limited
 (&amp;#x201C;Takeda&amp;#x201D;) terminating the worldwide license and
 collaboration agreement under which the Company and Takeda were
 jointly developing the Company&amp;#x2019;s proprietary compound ITI-214
 and other selected compounds that selectively inhibit
 phosphodiesterase type 1 (&amp;#x201C;PDE1&amp;#x201D;) for use in the
 prevention and treatment of human diseases. Through March&amp;#xA0;31,
 2015, the Company had received approximately $29.0 million in total
 payments under the agreement and was previously eligible to receive
 milestone payments and royalties based on net sales. The Company is
 in the process of refining its strategy for the PDE1 inhibitor
 program.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 In the first quarter of 2015, the Company moved its headquarters to
 430 East 29th Street, New York, New York 10016. The Company has
 entered into a long-term lease for approximately 16,753 square feet
 of useable laboratory and office space&lt;b&gt;.&amp;#xA0;&lt;/b&gt;The lease has a term of 11
 years. The Company expects that its facility related costs will
 increase moderately beginning in 2015 due to this new facility. A
 board member of the Company is a co-founder, Chairman of the board
 of directors, Chief Executive Officer, President and a director of
 the parent company to the landlord under this lease.&lt;/p&gt;

 On March&amp;#xA0;11, 2015, the Company completed a public offering of
 common stock in which the Company sold 5,411,481 shares of common
 stock, which included the exercise of the underwriters&amp;#x2019;
 option to purchase an additional 661,481 shares, at an offering
 price of $24.00 per share. After deducting underwriting discounts,
 commissions and offering expenses, the net proceeds to the Company
 were approximately $121.8 million.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 1px &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 In order to further its research projects and support its
 collaborations, the Company will require additional financing until
 such time, if ever, that revenue streams are sufficient to generate
 consistent positive cash flow from operations. Possible sources of
 funds include public or private sales of the Company&amp;#x2019;s equity
 securities, sales of debt securities, the incurrence of debt from
 commercial lenders, strategic collaborations, licensing a portion
 or all of the Company&amp;#x2019;s product candidates and technology
 and, to a lesser extent, grant funding. On August&amp;#xA0;29, 2014,
 the Company filed a universal shelf registration statement on Form
 S-3, which was declared effective by the Securities and Exchange
 Commission (the &amp;#x201C;SEC&amp;#x201D;) on September&amp;#xA0;15, 2014, to
 register $150 million of the Company&amp;#x2019;s common stock,
 preferred stock, various series of debt securities, warrants,
 rights and purchase contracts to purchase any of such securities,
 either individually or in units, for issuance from time to time at
 prices and on terms to be determined at the time of any such
 offering. After the public offering in March 2015, approximately
 $20.1 million of securities remains available for issuance under
 this shelf registration. This registration statement will remain in
 effect for up to three years from the initial effective date.&lt;/p&gt;

 The preparation of financial statements in conformity with
 generally accepted accounting principles requires management to
 make estimates and assumptions that affect the amounts reported in
 the financial statements and accompanying notes. Although actual
 results could differ from those estimates, management does not
 believe that such differences would be material.&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;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 The Company considers all highly liquid investments with a maturity
 of three months or less from the date of purchase to be cash
 equivalents. Cash and cash equivalents consist of checking
 accounts, money market accounts, money market funds, and
 certificates of deposit with a maturity date of three months or
 less. Certificates of deposit, commercial paper, corporate notes
 and corporate bonds with a maturity date of more than three months
 are classified separately on the balance sheet. Their carrying
 values approximate the fair market value.&lt;/p&gt;

 The Company has classified all of its investment securities
 available-for-sale, including those with maturities beyond one
 year, as current assets on the consolidated balance sheets based on
 the highly liquid nature of the investment securities and because
 these investment securities are considered available for use in
 current operations. As of March&amp;#xA0;31, 2015 and December&amp;#xA0;31,
 2014, the Company held $36.5 million and $31.8 million,
 respectively, of available-for-sale investment securities with
 contractual maturity dates more than one year and less than two
 years.&lt;/p&gt;

 The Company applies the fair value method under ASC Topic
 820,&amp;#xA0;&lt;i&gt;Fair Value
 Measurements and Disclosures&lt;/i&gt;. ASC Topic 820 defines fair value,
 establishes a fair value hierarchy for assets and liabilities
 measured at fair value and requires expanded disclosures about fair
 value measurements. The ASC Topic 820 hierarchy ranks the quality
 and reliability of inputs, or assumptions, used in the
 determination of fair value and requires assets and liabilities
 carried at fair value to be classified and disclosed in one of the
 following categories based on the lowest level input used that is
 significant to a particular fair value measurement:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 6pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 &lt;td valign="top" align="left"&gt;Level&amp;#xA0;1&amp;#x2014;Fair value is
 determined by using unadjusted quoted prices that are available in
 active markets for identical assets and liabilities.&lt;/td&gt;

 &lt;/table&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 6pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 &lt;td valign="top" align="left"&gt;Level&amp;#xA0;2&amp;#x2014;Fair value is
 determined by using inputs other than Level 1 quoted prices that
 are directly or indirectly observable. Inputs can include quoted
 prices for similar assets and liabilities in active markets or
 quoted prices for identical assets and liabilities in inactive
 markets. Related inputs can also include those used in valuation or
 other pricing models, such as interest rates and yield curves that
 can be corroborated by observable market data.&lt;/td&gt;

 &lt;td valign="top" width="1%"&gt;&amp;#xA0;&lt;/td&gt;
 &lt;td valign="top" align="left"&gt;Level&amp;#xA0;3&amp;#x2014;Fair value is
 determined by inputs that are unobservable and not corroborated by
 market data. Use of these inputs involves significant and
 subjective judgments to be made by a reporting entity&amp;#x2014;e.g.,
 determining an appropriate adjustment to a discount factor for
 illiquidity associated with a given security.&lt;/td&gt;
 &lt;/tr&gt;
 &lt;/table&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company evaluates financial assets and liabilities subject to
 fair value measurements on a recurring basis to determine the
 appropriate level at which to classify them each reporting period.
 This determination requires the Company to make subjective
 judgments as to the significance of inputs used in determining fair
 value and where such inputs lie within the ASC Topic 820
 hierarchy.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company has no assets or liabilities that were measured using
 quoted prices for significant unobservable inputs (Level 3 assets
 and liabilities) as of March&amp;#xA0;31, 2015 and December&amp;#xA0;31,
 2014. The carrying value of cash held in money market funds of
 approximately $22.6 million as of March&amp;#xA0;31, 2015 and $8.5
 million as of December&amp;#xA0;31, 2014, is included in cash and cash
 equivalents and approximates market value based on quoted market
 price or Level 1 inputs.&lt;/p&gt;

 The Company considers the recorded costs of its financial assets
 and liabilities, which consist of cash equivalents, accounts
 receivable, accounts payable and accrued liabilities, to
 approximate their fair value because of their relatively short
 maturities at March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2014.
 Management believes that the risks associated with its financial
 instruments are minimal as the counterparties are various
 corporations, financial institutions and government agencies of
 high credit standing.&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;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;Concentration of Credit Risk&lt;/b&gt;&lt;/p&gt;

 Cash equivalents are held with major financial institutions in the
 United States. Certificates of deposit held with banks may exceed
 the amount of insurance provided on such deposits. Generally, these
 deposits may be redeemed upon demand and, therefore, bear minimal
 risk.&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;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;Accounts Receivable&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;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Accounts receivable that management has the intent and ability to
 collect are reported in the balance sheets at outstanding amounts,
 less an allowance for doubtful accounts. The Company writes off
 uncollectible receivables when the likelihood of collection is
 remote.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company evaluates the collectability of accounts receivable on
 a regular basis. The allowance, if any, is based upon various
 factors including the financial condition and payment history of
 customers, an overall review of collections experience on other
 accounts and economic factors or events expected to affect future
 collections experience. No allowance was recorded as of
 March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2014, as the Company has
 a history of collecting on all of its accounts, including
 government agencies and collaborations funding its research.&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;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;Property and Equipment&lt;/b&gt;&lt;/p&gt;

 Property and equipment is stated at cost and depreciated on a
 straight-line basis over estimated useful lives ranging from three
 to five years. Leasehold improvements are amortized using the
 straight-line method over the shorter of the estimated useful life
 of the assets or the term of the related lease. Expenditures for
 maintenance and repairs are charged to operations as incurred.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 When indicators of possible impairment are identified, the Company
 evaluates the recoverability of the carrying value of its
 long-lived assets based on the criteria established in ASC
 Topic&amp;#xA0;360,&amp;#xA0;&lt;i&gt;Property, Plant and
 Equipment&lt;/i&gt;. The Company considers historical performance and
 anticipated future results in its evaluation of potential
 impairment. The Company evaluates the carrying value of those
 assets in relation to the operating performance of the business and
 undiscounted cash flows expected to result from the use of those
 assets. Impairment losses are recognized when carrying value
 exceeds the undiscounted cash flows, in which case management must
 determine the fair value of the underlying asset. No such
 impairment losses have been recognized to date.&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;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;Revenue Recognition&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;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Revenue is recognized when all terms and conditions of the
 agreements have been met, including that persuasive evidence of an
 arrangement exists, delivery has occurred or services have been
 rendered, the price is fixed or determinable and collectability is
 reasonably assured. The Company is reimbursed for certain costs
 incurred on specified research projects under the terms and
 conditions of grants, collaboration agreements, and awards. The
 Company records the amount of reimbursement as revenues on a gross
 basis in accordance with ASC Topic 605-45,&amp;#xA0;&lt;i&gt;Revenue
 Recognition/Principal Agent Considerations&lt;/i&gt;. The Company is the
 primary obligor with respect to purchasing goods and services from
 third-party suppliers, is obligated to compensate the service
 provider for the work performed, and has discretion in selecting
 the supplier. Provisions for estimated losses on research grant
 projects and any other contracts are made in the period such losses
 are determined.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 8%; -webkit-text-stroke-width: 0px"&gt;
 The Company has entered into arrangements involving the delivery of
 more than one element. Each required deliverable is evaluated to
 determine whether it qualifies as a separate unit of accounting.
 For the Company, this determination is generally based on whether
 the deliverable has &amp;#x201C;stand-alone value&amp;#x201D; to the
 customer. The Company adopted this accounting standard on a
 prospective basis for all Multiple-Deliverable Revenue Arrangements
 (&amp;#x201C;MDRAs&amp;#x201D;), entered into on or after January&amp;#xA0;1,
 2011, and for any MDRAs that were entered into prior to
 January&amp;#xA0;1, 2011, but materially modified on or after that
 date.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The adoption of this accounting standard did not have a material
 impact on the Company&amp;#x2019;s results of operations for the
 quarters ended March&amp;#xA0;31, 2015 and 2014, or on the
 Company&amp;#x2019;s financial positions as of March&amp;#xA0;31, 2015 and
 December&amp;#xA0;31, 2014.&lt;/p&gt;

 The Company adopted ASC Topic 605-28,&amp;#xA0;&lt;i&gt;Milestone Method&lt;/i&gt;. Under
 this guidance, the Company recognizes revenue contingent upon the
 achievement of a substantive milestone in its entirety in the
 period the milestone is achieved. Substantive milestone payments
 are recognized upon achievement of the milestone only if all of the
 following conditions are met:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 6pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 &lt;td valign="top" align="left"&gt;a reasonable amount of time passes

 Determination as to whether a payment meets the aforementioned
 conditions involves management&amp;#x2019;s judgment. If any of these
 conditions are not met, the resulting payment would not be
 considered a substantive milestone, and therefore, the resulting
 payment would be considered part of the consideration for the
 single unit of accounting and be recognized as revenue as such
 performance obligations are performed under either the proportional
 performance or straight-line methods, as applicable. In addition,
 the determination that one such payment was not a substantive
 milestone could prevent the Company from concluding that subsequent
 milestone payments were substantive milestones and, as a result,
 any additional milestone payments could also be considered part of
 the consideration for the single unit of accounting and would be
 recognized as revenue as such performance obligations are performed
 under either the proportional performance or straight-line methods,
 as applicable.&lt;/p&gt;

 &lt;b&gt;Research and Development&lt;/b&gt;&lt;/p&gt;

 Except for payments made in advance of services, the Company
 expenses its research and development costs as incurred. For
 payments made in advance, the Company recognizes research and
 development expense as the services are rendered. Research and
 development costs primarily consist of salaries and related
 expenses for personnel and resources and the costs of clinical
 trials. Other research and development expenses include
 pre-clinical analytical testing, outside services, providers,
 materials and consulting fees.&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;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;Income Taxes&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;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Income taxes are accounted for using the liability method. Deferred
 tax assets and liabilities are recognized for the future tax
 consequences attributable to differences between the financial
 statement carrying amounts of existing assets and liabilities and
 its respective tax bases. Deferred tax assets and liabilities are
 measured using enacted tax rates expected to apply to taxable
 income in the year in which those temporary differences are
 expected to be recovered or settled.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The effect on deferred tax assets and liabilities of a change in
 tax rates is recognized in income in the period that includes the
 enactment date. Valuation allowances are established when necessary
 to reduce net deferred tax assets to the amount expected to be
 realized. Income tax expense is the tax payable for the period and
 the change during the period in deferred tax assets and
 liabilities.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company accounts for uncertain tax positions pursuant to ASC
 Topic 740 (previously included in FASB Interpretation
 No.&amp;#xA0;48,&lt;i&gt;&amp;#xA0;Accounting for Uncertainty in
 Income Taxes&amp;#x2013;an Interpretation of FASB Statement
 No.&amp;#xA0;109)&lt;/i&gt;. Financial statement recognition of a tax
 position taken or expected to be taken in a tax return is
 determined based on a more-likely-than-not threshold of that
 position being sustained. If the tax position meets this threshold,
 the benefit to be recognized is measured as the tax benefit having
 the highest likelihood of being realized upon ultimate settlement
 with the taxing authority. The Company recognizes interest accrued
 related to unrecognized tax benefits and penalties in the provision
 for income taxes.&lt;/p&gt;

 &lt;b&gt;Comprehensive Income (Loss)&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;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 All components of comprehensive income (loss), including net income
 (loss), are reported in the financial statements in the period in
 which they are incurred. Comprehensive income (loss) is defined as
 the change in equity of a business enterprise during a period from
 transactions and other events and circumstances from non-owner
 sources. In accordance with accounting guidance, the Company
 presents the impact of any unrealized gains or (losses) on its
 investment securities in a separate statement of comprehensive
 income (loss) for each period.&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;; WIDOWS: 1; MARGIN-TOP: 18pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;Share-Based Compensation&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;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Share-based payments are accounted for in accordance with the
 provisions of ASC Topic&amp;#xA0;718,&amp;#xA0;&lt;i&gt;Compensation&amp;#x2014;Stock
 Compensation&lt;/i&gt;. The fair value of share-based payments is
 estimated, on the date of grant, using the Black-Scholes-Merton
 option-pricing model (the &amp;#x201C;Black-Scholes model&amp;#x201D;). The
 resulting fair value is recognized ratably over the requisite
 service period, which is generally the vesting period of the
 option.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 For all awards granted with time-based vesting conditions, expense
 is amortized using the straight-line attribution method. For awards
 that contain a performance condition, expense is amortized using
 the accelerated attribution method. As share-based compensation
 expense recognized in the statements of operations for the three
 months ended March&amp;#xA0;31, 2015 and 2014 is based on share-based
 awards ultimately expected to vest, it has been reduced for
 estimated forfeitures. ASC Topic 718 requires forfeitures to be
 estimated at the time of grant and revised, if necessary, in
 subsequent periods if actual forfeitures differ from those
 estimates. Pre-vesting forfeitures are based on the Company&amp;#x2019;s
 historical experience for the three months ended March&amp;#xA0;31,
 2015 and 2014, and have not been material.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company utilizes the Black-Scholes model for estimating fair
 value of its stock options granted. Option valuation models,
 including the Black-Scholes model, require the input of subjective
 assumptions, and changes in the assumptions used can materially
 affect the grant date fair value of an award. These assumptions
 include the risk-free rate of interest, expected dividend yield,
 expected volatility and the expected life of the award.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Expected volatility rates are based on historical volatility of the
 common stock of comparable publicly traded entities and other
 factors due to the lack of historic information of the
 Company&amp;#x2019;s common stock. The expected life of stock options is
 the period of time for which the stock options are expected to be
 outstanding. Given the lack of historic exercise data, the expected
 life is determined using the &amp;#x201C;simplified method&amp;#x201D; which
 is defined as the midpoint between the vesting date and the end of
 the contractual term.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The risk-free interest rates are based on the U.S. Treasury yield
 for a period consistent with the expected term of the option in
 effect at the time of the grant. The Company has not paid dividends
 to its stockholders since its inception and does not plan to pay
 cash dividends in the foreseeable future. Therefore, the Company
 has assumed an expected dividend rate of zero.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Prior to January&amp;#xA0;1, 2014, given that there was no active
 market for the Company&amp;#x2019;s common stock, the exercise price of
 the stock options on the date of grant was determined and approved
 by the board of directors using several factors, including progress
 and milestones achieved in the Company&amp;#x2019;s business development
 and performance, the price per share of its convertible preferred
 stock offerings and general industry and economic trends. In
 establishing the estimated fair value of the common stock, the
 Company considered the guidance set forth in American Institute of
 Certified Public Accountants Practice Guide,&amp;#xA0;&lt;i&gt;Valuation of
 Privately-Held-Company Equity Securities Issued as
 Compensation&lt;/i&gt;. For stock options granted in 2014 and 2015, the
 exercise price was determined by using the closing market price of
 the Company&amp;#x2019;s common stock on the date of grant.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Under ASC Topic 718, the cumulative amount of compensation cost
 recognized for instruments classified as equity that ordinarily
 would result in a future tax deduction under existing tax law shall
 be considered to be a deductible difference in applying ASC
 Topic&amp;#xA0;740,&amp;#xA0;&lt;i&gt;Income Taxes&lt;/i&gt;. The
 deductible temporary difference is based on the compensation cost
 recognized for financial reporting purposes; however, these
 provisions currently do not impact the Company, as all the deferred
 tax assets have a full valuation allowance.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Since the Company had net operating loss carryforwards as of
 March&amp;#xA0;31, 2015 and 2014, no excess tax benefits for the tax
 deductions related to share-based awards were recognized in the
 statements of 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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Equity instruments issued to non-employees are accounted for under
 the provisions of ASC Topic&amp;#xA0;718 and ASC Topic
 505-50,&amp;#xA0;&lt;i&gt;Equity/Equity-Based
 Payments to Non-Employees&lt;/i&gt;. Accordingly, the estimated fair
 value of the equity instrument is recorded on the earlier of the
 performance commitment date&amp;#xA0;or the date the services required
 are completed and are marked to market during the
 service&amp;#xA0;period.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 1px &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 18px; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &amp;#xA0;&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;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 &lt;b&gt;Loss Per Share&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;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Basic net loss per common share is determined by dividing the net
 loss allocable to common stockholders by the weighted-average
 number of common shares outstanding during the period, without
 consideration of common stock equivalents. Diluted net loss per
 share is computed by dividing the net loss allocable to common
 stockholders by the weighted-average number of common stock
 equivalents outstanding for the period. The treasury stock method
 is used to determine the dilutive effect of the Company&amp;#x2019;s
 stock option grants.&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;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The&amp;#xA0;following common stock equivalents were excluded in the
 calculation of diluted loss per share because their effect would be
 anti-dilutive as applied to the loss from operations for the three
 months ended March&amp;#xA0;31, 2015 and 2014:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 12pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 0pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 The Company sponsors the Intra-Cellular Therapies, Inc. 2013 Equity
 Incentive Plan (the &amp;#x201C;2013 Plan&amp;#x201D;) to provide for the
 granting of stock-based awards, such as stock options, restricted
 common stock, restricted stock units and stock appreciation rights
 to employees, directors and consultants as determined by the Board
 of Directors. In August 2013, the Company assumed in the Merger the
 ITI 2003 Equity Incentive Plan, as amended (the &amp;#x201C;2003
 Plan&amp;#x201D;), which expired by its terms in July 2013. As of
 March&amp;#xA0;31, 2015, the only outstanding awards under the 2003
 Plan were options to purchase 1,070,076 shares of common stock.
 Effective in November 2013, the Company adopted the 2013 Plan. The
 Company reserved 2,850,000 shares of common stock for issuance
 under the 2013 Plan. In both January 2015 and 2014, the number of
 shares of common stock reserved for issuance under the 2013 Plan
 automatically increased by 800,000 pursuant to the evergreen
 provisions of the 2013 Plan.&lt;/p&gt;

 Stock options granted under the 2013 Plan may be either incentive
 stock options (&amp;#x201C;ISOs&amp;#x201D;) as defined by the Internal
 Revenue Code of 1986, as amended, or non-qualified stock options.
 The Board of Directors determines who will receive options, the
 vesting periods (which are generally two to three years) and the
 exercise prices of such options. Options have a maximum term of 10
 years. The exercise price of ISOs granted under the 2013 Plan must
 be at least equal to the fair market value of the common stock on
 the date of&amp;#xA0;grant.&lt;/p&gt;

 The Company applies the fair value method under ASC Topic
 820,&amp;#xA0;&lt;i&gt;Fair Value
 Measurements and Disclosures&lt;/i&gt;. ASC Topic 820 defines fair value,
 establishes a fair value hierarchy for assets and liabilities
 measured at fair value and requires expanded disclosures about fair
 value measurements. The ASC Topic 820 hierarchy ranks the quality
 and reliability of inputs, or assumptions, used in the
 determination of fair value and requires assets and liabilities
 carried at fair value to be classified and disclosed in one of the
 following categories based on the lowest level input used that is
 significant to a particular fair value measurement:&lt;/p&gt;

 &lt;td valign="top" align="left"&gt;Level&amp;#xA0;3&amp;#x2014;Fair value is
 determined by inputs that are unobservable and not corroborated by
 market data. Use of these inputs involves significant and
 subjective judgments to be made by a reporting entity&amp;#x2014;e.g.,
 determining an appropriate adjustment to a discount factor for
 illiquidity associated with a given security.&lt;/td&gt;

 The Company evaluates financial assets and liabilities subject to
 fair value measurements on a recurring basis to determine the
 appropriate level at which to classify them each reporting period.
 This determination requires the Company to make subjective
 judgments as to the significance of inputs used in determining fair
 value and where such inputs lie within the ASC Topic 820
 hierarchy.&lt;/p&gt;

 The Company has no assets or liabilities that were measured using
 quoted prices for significant unobservable inputs (Level 3 assets
 and liabilities) as of March&amp;#xA0;31, 2015 and December&amp;#xA0;31,
 2014. The carrying value of cash held in money market funds of
 approximately $22.6 million as of March&amp;#xA0;31, 2015 and $8.5
 million as of December&amp;#xA0;31, 2014, is included in cash and cash
 equivalents and approximates market value based on quoted market
 price or Level 1 inputs.&lt;/p&gt;

 The Company considers the recorded costs of its financial assets
 and liabilities, which consist of cash equivalents, accounts
 receivable, accounts payable and accrued liabilities, to
 approximate their fair value because of their relatively short
 maturities at March&amp;#xA0;31, 2015 and December&amp;#xA0;31, 2014.
 Management believes that the risks associated with its financial
 instruments are minimal as the counterparties are various
 corporations, financial institutions and government agencies of
 high credit standing.&lt;/p&gt;

  <us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy contextRef="eol_PE899285--1510-Q0001_STD_90_20150331_0" id="id_5726958_20C51C31-A860-4FC9-97DE-1FA878B62C44_1_0">&lt;div&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;Share-Based Compensation&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 Share-based payments are accounted for in accordance with the
 provisions of ASC Topic&amp;#xA0;718, &lt;i&gt;Compensation&amp;#x2014;Stock
 Compensation&lt;/i&gt;. The fair value of share-based payments is
 estimated, on the date of grant, using the Black-Scholes-Merton
 option-pricing model (the &amp;#x201C;Black-Scholes model&amp;#x201D;). The
 resulting fair value is recognized ratably over the requisite
 service period, which is generally the vesting period of the
 option.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 For all awards granted with time-based vesting conditions, expense
 is amortized using the straight-line attribution method. For awards
 that contain a performance condition, expense is amortized using
 the accelerated attribution method. As share-based compensation
 expense recognized in the statements of operations for the three
 months ended March&amp;#xA0;31, 2015 and 2014 is based on share-based
 awards ultimately expected to vest, it has been reduced for
 estimated forfeitures. ASC Topic 718 requires forfeitures to be
 estimated at the time of grant and revised, if necessary, in
 subsequent periods if actual forfeitures differ from those
 estimates. Pre-vesting forfeitures are based on the Company&amp;#x2019;s
 historical experience for the three months ended March&amp;#xA0;31,
 2015 and 2014, and have not been material.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The Company utilizes the Black-Scholes model for estimating fair
 value of its stock options granted. Option valuation models,
 including the Black-Scholes model, require the input of subjective
 assumptions, and changes in the assumptions used can materially
 affect the grant date fair value of an award. These assumptions
 include the risk-free rate of interest, expected dividend yield,
 expected volatility and the expected life of the award.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Expected volatility rates are based on historical volatility of the
 common stock of comparable publicly traded entities and other
 factors due to the lack of historic information of the
 Company&amp;#x2019;s common stock. The expected life of stock options is
 the period of time for which the stock options are expected to be
 outstanding. Given the lack of historic exercise data, the expected
 life is determined using the &amp;#x201C;simplified method&amp;#x201D; which
 is defined as the midpoint between the vesting date and the end of
 the contractual term.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The risk-free interest rates are based on the U.S. Treasury yield
 for a period consistent with the expected term of the option in
 effect at the time of the grant. The Company has not paid dividends
 to its stockholders since its inception and does not plan to pay
 cash dividends in the foreseeable future. Therefore, the Company
 has assumed an expected dividend rate of zero.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Prior to January&amp;#xA0;1, 2014, given that there was no active
 market for the Company&amp;#x2019;s common stock, the exercise price of
 the stock options on the date of grant was determined and approved
 by the board of directors using several factors, including progress
 and milestones achieved in the Company&amp;#x2019;s business development
 and performance, the price per share of its convertible preferred
 stock offerings and general industry and economic trends. In
 establishing the estimated fair value of the common stock, the
 Company considered the guidance set forth in American Institute of
 Certified Public Accountants Practice Guide, &lt;i&gt;Valuation of
 Privately-Held-Company Equity Securities Issued as
 Compensation&lt;/i&gt;. For stock options granted in 2014 and 2015, the
 exercise price was determined by using the closing market price of
 the Company&amp;#x2019;s common stock on the date of grant.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Under ASC Topic 718, the cumulative amount of compensation cost
 recognized for instruments classified as equity that ordinarily
 would result in a future tax deduction under existing tax law shall
 be considered to be a deductible difference in applying ASC
 Topic&amp;#xA0;740, &lt;i&gt;Income Taxes&lt;/i&gt;. The deductible temporary
 difference is based on the compensation cost recognized for
 financial reporting purposes; however, these provisions currently
 do not impact the Company, as all the deferred tax assets have a
 full valuation allowance.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Since the Company had net operating loss carryforwards as of
 March&amp;#xA0;31, 2015 and 2014, no excess tax benefits for the tax
 deductions related to share-based awards were recognized in the
 statements of operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Equity instruments issued to non-employees are accounted for under
 the provisions of ASC Topic&amp;#xA0;718 and ASC Topic 505-50,
 &lt;i&gt;Equity/Equity-Based Payments to Non-Employees&lt;/i&gt;. Accordingly,
 the estimated fair value of the equity instrument is recorded on
 the earlier of the performance commitment date&amp;#xA0;or the date the
 services required are completed and are marked to market during the
 service&amp;#xA0;period.&lt;/p&gt;
