Ltd., or Maruishi, and Chong Kun Dang Pharmaceutical Corp., or CKDP, and an earlier product candidate for which development efforts ceased in 2007. Additionally, in May 2018, the Company received net proceeds of $14,556 from the issuance and sale of 1,174,827 shares of the Company&#8217;s common stock to Vifor (International) Ltd., or Vifor, in connection with the license agreement with VFMCRP (see Note 10, <font style="font-style:italic;">Collaborations and Licensing Agreements</font>). </p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As of June 30, 2018, the Company had unrestricted cash and cash equivalents and marketable securities of $131,961 and an accumulated deficit of $254,302. The Company has incurred substantial net losses and negative cash flows from operating activities in nearly every fiscal period since inception and expects this trend to continue for the foreseeable future. The Company recognized net losses of $17,194 and $9,300 for the three months ended June 30, 2018 and 2017, respectively, and $33,961 and $31,504 for the six months ended June 30, 2018 and 2017, respectively, and had net cash provided by (used in) operating activities of $22,552 and $(33,563) for the six months ended June 30, 2018 and 2017, respectively. </p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:3.57%;font-size:10pt;">&nbsp;</p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In July 2018, the Company received net proceeds of approximately $92,026 from the issuance and sale of 5,175,000<font style="Background-color:#FFFFFF;"> shares of its common stock in a follow-on public offering, </font>including the full exercise of the underwriters&#8217; option to purchase 675,000 additional shares of its common stock<font style="Background-color:#FFFFFF;"> (see Note 16, </font><font style="font-style:italic;Background-color:#FFFFFF;">Subsequent Event</font><font style="Background-color:#FFFFFF;">).</font></p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company is subject to risks common to other life science companies including, but not limited to, uncertainty of product development and commercialization, lack of marketing and sales history, development by its competitors of new technological innovations, dependence on key personnel, market acceptance of products, product liability, protection of proprietary technology, ability to raise additional financing, and compliance with Food and Drug Administration, or FDA, and other government regulations.&nbsp;&nbsp;If the Company does not successfully commercialize any of its product candidates, it will be unable to generate recurring product revenue or achieve profitability.&nbsp;&nbsp;</p></div>

Significant estimates include the fair value of marketable securities that are classified as level 2 of the fair value hierarchy, useful lives of fixed assets, the periods over which certain revenues will be recognized, including licensing and collaborative revenue recognized from non-refundable up-front and milestone payments, the determination of prepaid research and development, or R&amp;D, clinical costs and accrued research projects, the amount of non-cash compensation costs related to share-based payments to employees and non-employees and the periods over which those costs are expensed and the likelihood of realization of deferred tax assets. </p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;font-style:italic;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;text-transform:none;font-variant: normal;">Significant Accounting Policies</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">There have been no material changes to the significant accounting policies previously disclosed in Note 2 to the Financial Statements in the Company&#8217;s Annual Report on Form 10-K for the year ended December 31, 2017, except for the recent adoption of new accounting pronouncements as disclosed below.</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;font-style:italic;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;text-transform:none;font-variant: normal;">Accounting Pronouncements Recently Adopted</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;font-style:italic;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;text-transform:none;font-variant: normal;">Revenue Recognition</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">On January 1, 2018, the Company adopted Accounting Standards Update, or ASU, 2014-09, <font style="font-style:italic;">Revenue from Contracts with Customers (Topic 606)</font>, or ASC 606, as amended by ASU 2016-08, 2016-10, 2016-12 and 2016-20 using the full retrospective method. Under ASC 606, the Company recognizes revenue in an amount that reflects the consideration to which it expects to be entitled in exchange for the transfer of promised goods or services to customers. To determine revenue recognition for contracts with customers that are within the scope of ASC 606, the Company performs the following steps: (1) identifies the contract with the customer, (2) identifies the performance obligations in the contract, (3) determines the transaction price, (4) allocates the transaction price to the performance obligations in the contract, and (5) recognizes revenue when (or as) the entity satisfies a performance obligation. The Company has concluded that upon adoption of ASC 606, as amended, there was no impact on its results of operations, financial position or cash flows for any period presented from its only two revenue-related contracts, which were in effect at that time: the CKDP Agreement or the Maruishi Agreement (see Note 10, <font style="font-style:italic;">Collaboration and Licensing Agreements</font> and Note 11, <font style="font-style:italic;">Revenue Recognition)</font>.</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company has entered into agreements to license its intellectual property, or IP, related to CR845/difelikefalin to develop, manufacture and/or commercialize drug products. These agreements typically contain multiple performance obligations, including licenses of IP and R&amp;D services. Payments to the Company under these agreements may include nonrefundable license fees, payments for research activities, payments based upon the achievement of certain milestones and royalties on any resulting net product sales.</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company identifies agreements as contracts that create enforceable rights and obligations when the agreement is approved by the parties, identifies the rights of the parties and the payment terms, has commercial substance and it is probable that the Company will collect the consideration to which it will be entitled in exchange for the goods and services that will be transferred to the customer. The counterparty is considered to be a customer when it has contracted with the Company to obtain goods and services that are the output of the Company&#8217;s ordinary activities (i.e., development of pharmaceutical products) in exchange for consideration.</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">A performance obligation is a promise to transfer distinct goods or services to a customer. Performance obligations that are both capable of being distinct and distinct within the context of the contract are considered to be separate performance obligations. Performance obligations are capable of being distinct if the counterparty is able to benefit from the good or service on its own or together with other resources that are readily available to it. Performance obligations are distinct within the context of the contract when each performance obligation is separately identifiable from each other; i.e., the Company is not using the goods or services as inputs to produce or deliver the combined output or outputs specified by the customer; one or more of the goods or services does not significantly modify or customize one of the other goods or services in the contract; and goods or services are not highly interdependent or not highly interrelated. Performance obligations that are not distinct are accounted for as a single performance obligation over the period that goods or services are transferred to the customer. The determination of whether performance obligations in a contract are distinct may require significant judgment.</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The transaction price is the amount of consideration that the Company expects to be entitled to in exchange for transferring promised goods or services to the customer based on the contract terms at inception of a contract. There is a constraint on inclusion of variable consideration related to licenses of IP, such as milestone payments or sales-based royalty payments, in the transaction price if there is uncertainty at inception of the contract as to whether such consideration will be recognized in the future because it is probable that there will be a significant reversal of revenue in the future when the uncertainty is resolved.<font style="font-size:12pt;"> </font>The determination of whether or not it is probable that a significant reversal of revenue will occur in the future depends on the likelihood and magnitude of the reversal.&nbsp;&nbsp;Factors that could increase the likelihood or magnitude of a reversal of revenue include (a) the susceptibility of the amount of consideration to factors outside the entity&#8217;s influence, such as the outcome of clinical trials, the timing of initiation of clinical trials by the counterparty and the approval of drug product candidates by regulatory agencies, (b) situations in which the uncertainty is not expected to be resolved for a long period of time and (c) level of the Company&#8217;s experience in the field.<font style="font-size:12pt;"> </font>When it becomes probable that events will occur, for which variable consideration was constrained at inception of the contract, the Company allocates the related consideration to the separate performance obligations in the same manner as described below.&nbsp;&nbsp;</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">At inception of a contract, the Company allocates the transaction price to the distinct performance obligations based upon their relative standalone selling prices. Standalone selling price is the price at which an entity would sell a promised good or service separately to a customer. The best evidence of standalone selling price is an observable price of a good or service when sold separately by an entity in similar circumstances to similar customers. Since the Company typically does not have such evidence, it estimates standalone selling price so that the amount that is allocated to each performance obligation equals the amount that the Company expects to receive for transferring goods or services. The methods that the Company uses to make such estimates include (1) the adjusted market assessment approach, under which the Company forecasts and analyzes CR845/difelikefalin in the appropriate market, the phase of clinical development as well as considering recent similar license arrangements within the same phase of clinical development, therapeutic area, type of agreement, etc. and (2) the expected cost of satisfying the performance obligations plus a margin, or the expected cost plus a margin approach. </p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company recognizes revenue when, or as, it satisfies a performance obligation by transferring a promised good or service to a customer and the customer obtains control of the good or service. Revenue related to the grant of a license that is a distinct performance obligation and that is deemed to be functional IP is recognized at the point in time that the Company has the right to payment for the license, the customer has legal title to the license and can direct the use of the license (for example, to grant sublicenses), the customer has the significant risks and rewards of ownership of the license and the customer has accepted the asset (license) by signing the license agreement.</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Recognition of revenue related to R&amp;D services that are a distinct performance obligation or that are combined with granting of a license as a single performance obligation is deferred at inception of a contract and is recognized as those services are performed based on the costs incurred as a percentage of the estimated total costs to be incurred to complete the performance obligation. </p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Milestone payments are considered to be variable consideration and are not included in the transaction price at inception of the contract if it is uncertain that the milestone will be achieved. Rather, when it becomes probable that the milestone will be achieved and, therefore, there will not be a significant reversal of revenue in future periods, the respective amount to be earned is included in the transaction price, allocated to the distinct performance obligations based on their relative standalone selling price and recognized as revenue, as described above.&nbsp;&nbsp;Sales milestones and sales-based royalty payments related to a license of IP are recognized as revenue when the respective sales occur.</p> <p style="margin-bottom:0pt;margin-top:10pt;text-indent:3.57%;font-style:italic;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;text-transform:none;font-variant: normal;">Other Accounting Pronouncements Recently Adopted</p> <p style="margin-bottom:0pt;margin-top:10pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As of January 1, 2018, the Company adopted ASU No. 2017-09, <font style="font-style:italic;">Compensation &#8211; Stock Compensation (Topic 718) - Scope of Modification Accounting</font>, or ASU 2017-09, which clarifies that a change to the terms or conditions of a share-based payment award should be accounted for as a modification only if the fair value, vesting conditions or classification (as equity or liability) of the award changes as a result of the change in terms or conditions. Modification of a share-based payment award may result in the Company recognizing additional compensation expense. The Company generally has not modified, and does not expect to frequently modify, the fair value, vesting conditions or classification of its share-based payment awards.&nbsp;&nbsp;The Company does not expect this guidance to have a material effect on its financial position, results of operations or cash flows. However, if and when modifications occur, their effect could be material to the Company&#8217;s financial position, results of operations or cash flows (see Note 13, <font style="font-style:italic;">Stock-based Compensation</font>).&nbsp;&nbsp;</p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As of January 1, 2018, the Company adopted <font style="font-size:12pt;color:#000000;"></font><font style="text-decoration:none;">ASU</font><font style="font-size:12pt;color:#000000;"></font> No. 2017-01, <font style="font-style:italic;">Business Combinations (Topic 805), Clarifying the Definition of a Business, </font>or ASU 2017-01<font style="font-style:italic;">, </font>that clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 requires an entity to evaluate if substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. ASU 2017-01 also requires a business to include at least an input and one substantive process that together significantly contribute to the ability to create output and removes the evaluation of whether a market participant could replace missing elements. The adoption of ASU 2017-01 did not have a material effect on the Company&#8217;s financial position, results of operations or cash flows. </p> <p style="margin-top:10pt;margin-bottom:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As of January 1, 2018, the Company adopted ASU No. 2016-18, <font style="font-style:italic;">Statement of Cash Flows (Topic 230), Restricted Cash </font>(a consensus of the Emerging Issues Task Force), or ASU 2016-18, which changes the presentation of the cash flow statement to include amounts generally described as restricted cash or restricted cash equivalents, together with cash and cash equivalents, when reconciling the beginning-of-period and end-of-period amounts shown on the statement of cash flows. ASU 2016-18 also requires additional disclosures concerning the nature of the restrictions on cash and cash equivalents and a reconciliation between amounts of cash, cash equivalents and restricted cash on the balance sheet and statement of cash flows for each period presented. Upon adoption, ASU 2016-18 was applied retrospectively to all periods presented. The Company historically presented changes in restricted cash as an investing activity in the statement of cash flows. Upon adoption of ASU 2016-18, such changes are reflected in the beginning and ending balances of cash, cash equivalents and restricted cash for all periods presented (see Note 6, <font style="font-style:italic;">Restricted Cash</font>).</p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-size:10pt;">&nbsp;</p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:3.57%;font-style:italic;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;text-transform:none;font-variant: normal;">Accounting Pronouncements Not Yet Adopted</p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:3.57%;font-size:10pt;">&nbsp;</p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In June 2018, the FASB issued ASU No. 2018-07, <font style="font-style:italic;">Compensation&#8212;Stock Compensation (Topic 718)</font>,<font style="font-style:italic;"> Improvements to Nonemployee Share-Based Payment Accounting</font>, or ASU 2018-07, which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor&#8217;s own operations by issuing share-based payment awards. Accordingly, under ASU 2018-07, the fair value of stock options granted to nonemployees will be measured only on the grant date, the amount of which will be recognized as compensation expense over the nonemployee&#8217;s service (vesting) period in the same period(s) and in the same manner as if the Company had paid cash for the goods or services instead of paying with or using share-based payment awards. On an award-by-award basis, the Company may elect to use the contractual term as the expected term when estimating the fair value of a nonemployee award to satisfy the measurement objective. Prior guidance under Subtopic 505-50 required the fair value of nonemployee stock options to be marked to market at each reporting period during the service period, which resulted in volatility of compensation expense during that period. ASU 2018-07 is effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity&#8217;s adoption date of Topic 606. The Company will adopt ASU 2018-07 on January 1, 2019 on a modified retrospective basis through a cumulative-effect adjustment to equity by remeasuring, on that date, the fair value of all outstanding unvested stock options that had been granted to nonemployees. The Company expects that the adoption of ASU 2018-07 will not have a material effect on its results of operations, financial position or cash flows because grants of stock options to non-employees have been insignificant.&nbsp;&nbsp;</p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:3.57%;font-size:10pt;">&nbsp;</p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:3.57%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In February 2016, the FASB issued ASU No. 2016-02, <font style="font-style:italic;">Leases (Topic 842)</font>, or ASU 2016-02, which amends the current guidance for the accounting and disclosure of leases (ASC 840) for both lessees and lessors. The Company is currently identifying its contracts that contain leases. The primary effect of adoption will be the requirement to record right-of-use assets and corresponding lease obligations for those current operating leases. ASU 2016-02 is effective for interim and annual periods beginning after December 31, 2018 but may be adopted earlier. ASU 2016-02 requires modified retrospective adoption. However, the FASB issued ASU 2018-11, <font style="font-style:italic;">Leases (Topic 842): Targeted Improvements</font>, or ASU 2018-11, which allows entities to elect to continue to apply the guidance in ASC 840, including its disclosure requirements, in the comparative periods presented in the year that they adopt the new leases guidance in ASC 842. Entities that elect this option would record the cumulative effect of adoption on the effective date rather than at the beginning of the earliest comparative period presented. The Company does not expect that ASU 2016-02 or ASU 2018-11 will have a material impact on its Condensed Statements of Comprehensive Loss or its Condensed Statements of Cash Flows, but it does expect that upon adoption, it will have a material impact on the assets and liabilities on the Condensed Balance Sheets.&nbsp;&nbsp;&nbsp;&nbsp; </p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-size:10pt;">&nbsp;</p></div>
