The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary difference between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance. The Company may in the future determine that certain deferred tax assets will likely be realized, in which case the Company will reduce its valuation allowance in the period in which such determination is made. If the valuation allowance is reduced, the Company may recognize a benefit from income taxes in its statement of operations in that period. The Company classifies interest recognized pursuant to its deferred tax assets as interest expense, when appropriate.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxPolicyTextBlock>

The ASU is intended to define management&amp;#x2019;s responsibility to evaluate whether there is substantial doubt about an organization&amp;#x2019;s ability to continue as a going concern and to provide related footnote disclosures. For all entities, the ASU is effective for annual periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016.&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).

The Company&amp;#x2019;s ability to fund its planned clinical operations, including completion of its planned trials, is expected to depend on the amount and timing of cash receipts from future collaboration or product sales and/or financing transactions.&lt;/div&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

ASC 718 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the statements of operations based on their grant date fair values. For stock options granted to employees and to members of the board of directors for their services on the board of directors, the Company estimates the grant date fair value of each option award using the Black-Scholes option-pricing model. The use of the Black-Scholes option-pricing model requires management to make assumptions with respect to the expected term of the option, the expected volatility of the common stock consistent with the expected life of the option, risk-free interest rates and expected dividend yields of the common stock. For awards subject to service-based vesting conditions, the Company recognizes share-based compensation expense, equal to the grant date fair value of stock options on a straight-line basis over the requisite service period.&lt;/div&gt;&lt;div style=" font-size: 10pt;

Certain information and disclosures normally included in the notes to the annual consolidated financial statements prepared in accordance with GAAP have been omitted from these interim unaudited consolidated financial statements pursuant to the rules and regulations of the SEC.

Actual results could differ from those estimates.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Prior to the completion of it initial public offering in April 2015, the Company utilized significant estimates and assumptions in determining the fair value of its common stock. The board of directors determined the estimated fair value of the Company&amp;#x2019;s common stock based on a number of objective and subjective factors, including the prices at which the Company sold shares of its common stock to third parties and external market conditions affecting the biotechnology industry sector.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Research and Development Costs &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;All research and development costs are charged to expense as incurred. Research and development costs include salaries and personnel-related costs, consulting fees, fees paid for contract research services, the costs of laboratory equipment and facilities, license fees and other external costs. Costs incurred to acquire licenses for intellectual property to be used in research and development activities with no alternative future use are expensed as incurred as research and development.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Income Taxes &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company makes estimates and judgments in determining the need for a provision for income taxes, including the estimation of its taxable income or loss for the each full fiscal year. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary difference between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance. The Company may in the future determine that certain deferred tax assets will likely be realized, in which case the Company will reduce its valuation allowance in the period in which such determination is made. If the valuation allowance is reduced, the Company may recognize a benefit from income taxes in its statement of operations in that period. The Company classifies interest recognized pursuant to its deferred tax assets as interest expense, when appropriate.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Share-Based Compensation &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company accounts for its share-based compensation awards in accordance with ASC Topic 718, &lt;div style="display: inline; font-style: italic;"&gt;Compensation-Stock Compensation&lt;/div&gt; (&amp;#x201c;ASC 718&amp;#x201d;). ASC 718 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the statements of operations based on their grant date fair values. For stock options granted to employees and to members of the board of directors for their services on the board of directors, the Company estimates the grant date fair value of each option award using the Black-Scholes option-pricing model. The use of the Black-Scholes option-pricing model requires management to make assumptions with respect to the expected term of the option, the expected volatility of the common stock consistent with the expected life of the option, risk-free interest rates and expected dividend yields of the common stock. For awards subject to service-based vesting conditions, the Company recognizes share-based compensation expense, equal to the grant date fair value of stock options on a straight-line basis over the requisite service period.&lt;/div&gt;

 &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company considers highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents consisted primarily of cash on deposit in U.S., German, Swiss and Canadian banks. Cash and cash equivalents are stated at cost which approximates fair value.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Concentrations of Credit Risk &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents. The Company holds these investments in highly-rated financial institutions, and limits the amounts of credit exposure to any one financial institution. These amounts at times may exceed federally insured limits. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds. The Company has no off-balance sheet concentrations of credit risk, such as foreign currency exchange contracts, option contracts or other hedging arrangements.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Fair Value Measurements &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company follows ASC Topic 820, &lt;div style="display: inline; font-style: italic;"&gt;Fair Value Measurements and Disclosures&lt;/div&gt;, which establishes a fair value hierarchy for those instruments measured at fair value that distinguishes between assumptions based on market date (observable inputs) and the Company&amp;#x2019;s own assumptions (unobservable inputs). The hierarchy consists of three levels:&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; width: 700px;"&gt;       &lt;tr style="vertical-align: top"&gt;     &lt;td style="width: 30.6pt"&gt;&lt;/td&gt;     &lt;td style="width: 18.35pt"&gt;&amp;#x2022;&lt;/td&gt;     &lt;td&gt;Level 1&amp;#x2014;Unadjusted quoted prices in active markets for identical assets or liabilities.&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;  &lt;div style=" margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt;  &lt;table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; width: 700px;"&gt;       &lt;tr style="vertical-align: top"&gt;     &lt;td style="width: 30.6pt"&gt;&lt;/td&gt;     &lt;td style="width: 18.35pt"&gt;&amp;#x2022;&lt;/td&gt;     &lt;td&gt;Level 2&amp;#x2014;Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;    &lt;!-- Field: Page; Sequence: 12 --&gt;      &lt;!-- Field: /Page --&gt;    &lt;table cellpadding="0" cellspacing="0" style="font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; width: 700px;"&gt;       &lt;tr style="vertical-align: top"&gt;     &lt;td style="width: 30.6pt"&gt;&lt;/td&gt;     &lt;td style="width: 18.35pt"&gt;&amp;#x2022;&lt;/td&gt;     &lt;td&gt;Level 3&amp;#x2014;Unobservable inputs that reflect the Company&amp;#x2019;s own assumptions about the assumptions market participants would use in pricing the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.&lt;/td&gt;    &lt;/tr&gt;     &lt;/table&gt;  &lt;div style=" margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;At March 31, 2016 and December 31, 2015, the Company did not have any assets or liabilities that are measured at fair value on a recurring basis.

Potential impairment is assessed when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be recovered. Recoverability of these assets is assessed based on undiscounted expected future cash flows from the assets, considering a number of factors, including past operating results, budgets and economic projections, market trends and product development cycles. If impairments are identified, assets are written down to their estimated fair value. The Company has not recognized any impairment through March 31, 2016.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Foreign Currency Transactions &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Certain transactions are denominated in a currency other than the Company&amp;#x2019;s functional currency of the U.S. dollar, and the Company generates assets and liabilities that are fixed in terms of the amount of foreign currency that will be received or paid. At each balance sheet, the Company adjusts the assets and liabilities to reflect the current exchange rate, resulting in a translation gain or loss. Transaction gains and losses are also realized upon a settlement of a foreign currency transaction in determining net loss for the period in which the transaction is settled.&lt;/div&gt;    &lt;!-- Field: Page; Sequence: 13 --&gt;      &lt;!-- Field: /Page --&gt;    &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Comprehensive Income (Loss)&lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;ASC Topic 220, &lt;div style="display: inline; font-style: italic;"&gt;Comprehensive Income&lt;/div&gt;, requires that all components of comprehensive income (loss), including net income (loss), be reported in the financial statements in the period in which they are recognized. Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources, including unrealized gains and losses on investments and foreign currency translation adjustments.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Segment and Geographic Information &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision making group, in making decisions on how to allocate resources and assess performance. The Company&amp;#x2019;s chief operating decision maker is the Chief Executive Officer. The Company and the chief operating decision maker view the Company&amp;#x2019;s operations and manage its business as one operating segment. Substantially all of the Company&amp;#x2019;s operations are in the U.S. geographic segment.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Net Loss Per Share &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;Net loss per share (&amp;#x201c;EPS&amp;#x201d;) is computed by dividing net loss by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net loss by the weighted average number of common shares and common share equivalents outstanding (if dilutive) during each period. The number of common share equivalents, which include stock options, is computed using the treasury stock method.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Subsequent Events &lt;/div&gt;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;The Company considered events or transactions occurring after the balance sheet date but prior to the date the consolidated financial statements are available to be issued for potential recognition or disclosure in its consolidated financial statements.

The ASU is intended to define management&amp;#x2019;s responsibility to evaluate whether there is substantial doubt about an organization&amp;#x2019;s ability to continue as a going concern and to provide related footnote disclosures. For all entities, the ASU is effective for annual periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The core change with ASU 2016-2 is the requirement for the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the effect that the adoption of ASU 2016-02 will have on its financial statements.&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt;  &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;In March 2016, the FASB issued ASU No. 2016-09, &amp;#x201c;Improvements to Employee Share-Based Payment Accounting,&amp;#x201d; or ASU 2016-09, which amends ASC Topic 718, &amp;#x201c;Compensation &amp;#x2013; Stock Compensation.&amp;#x201d; ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The standard is effective for fiscal years beginning after December 31, 2016, and interim periods within those years and early adoption is permitted. The Company is currently evaluating how the adoption of this standard will impact its consolidated financial statements.&lt;/div&gt;&lt;/div&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>
