Upon closing, Janssen paid XBiotech &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$750&lt;/div&gt; million, with &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$75&lt;/div&gt; million held in an interest-bearing escrow account for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;18&lt;/div&gt; months to satisfy indemnity claims. There are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; known asserted or unasserted claims with regard to the intellectual property as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2019. &lt;/div&gt;In accordance with the agreement, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;ten&lt;/div&gt; Company employees from various departments were transferred to Janssen. Additionally, Janssen will pay the Company up to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;four&lt;/div&gt; milestone payments of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$150&lt;/div&gt; million each if it receives specified commercial authorizations within a specified timeframe for a pharmaceutical product that contains bermekimab and is for a non-dermatological indication. This represents contingent consideration; the Company has made a policy election &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; to recognize any amounts associated with these milestone payments upon execution of the arrangement and treat all amounts as a form of gain contingency. As &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; amount is currently reasonably certain of collection, these milestone payments were &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; included in the consideration in the contract. This transaction was accounted for as a sale of a business.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 55; Value: 2 --&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;The Company and Janssen also entered into an IP Non-Assertion and License Agreement, pursuant to which the Company granted Janssen a non-exclusive license to certain of its patents and intellectual property. Janssen granted the Company a non-exclusive license back of certain intellectual property rights and agreed &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; to assert certain claims from the patents acquired from the Company in the Janssen Transaction against the Company in connection with the Company&amp;#x2019;s new antibodies targeting IL-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1&amp;#x237a;&lt;/div&gt; as described in the Purchase Agreement, to treat non-dermatological diseases. In addition, the Company entered into a Clinical Manufacturing Agreement, under which XBiotech USA agreed to manufacture bermekimab for use by Janssen in clinical trials, in exchange for fixed payments, paid in quarterly installments. Finally, The Company and Janssen entered into a Transition Services Agreement, under which XBiotech USA agreed to continue operational management, on a fee-for-service basis, of certain ongoing clinical trials related to bermekimab.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;As a result of Janssen Transaction, the Company recognized a gain of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$750&lt;/div&gt; million in non-operating income. Of the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$750&lt;/div&gt; million, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$675&lt;/div&gt; million was received and booked in cash and the remaining &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$75&lt;/div&gt; million is held in an interest-bearing escrow account for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;18&lt;/div&gt; months and booked in long term assets as a receivable. In addition, the Company received a prepayment of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$4.5&lt;/div&gt; million from Janssen related to the clinical manufacturing agreement that will be performed in the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; quarter in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2020,&lt;/div&gt; which the Company determined to be &amp;#x201c;at market&amp;#x201d; in exchange for the services in the clinical manufacturing agreement. The Company booked the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$4.5&lt;/div&gt; million within contract liabilities. Substantially all amounts transferred related to IPR&amp;amp;D, and as such, there was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; carrying value of the amounts disposed in the Janssen Transaction.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;Additionally, the Company incurred approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$572&lt;/div&gt; thousand in expense due to professional fees. The Company determined the costs were &amp;#x201c;at market&amp;#x201d; and did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; result in any additional consideration with respect to the sale.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;Income in the consolidated statement of cash flows includes the gain resulting from the Janssen Transaction.

font-style: normal;"&gt; December 22, 2017, &lt;/div&gt;the President of the United States signed into law the Tax Cuts and Jobs Act, or TCJA, tax reform legislation. TJCA significantly changes U.S. tax law by, among other things, lowering U.S. corporate income tax rates and implementing a territorial tax system. TCJA reduced the U.S corporate tax rate from &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;35%&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;21%,&lt;/div&gt; effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 1, 2018.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;In connection with the initial analysis of the impact of TJCA, the Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;21%.&lt;/div&gt; The remeasurement of the Company&amp;#x2019;s&amp;#x2019; deferred tax balance was offset by application of its valuation allowance. The Company applied the guidance in SAB &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;118&lt;/div&gt; when accounting for the enactment-date effects of the Act in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017&lt;/div&gt; and throughout &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018.&lt;/div&gt; During &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018,&lt;/div&gt; the Company completed its &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017&lt;/div&gt; income tax returns and its accounting for the enactment-date income tax effects of TCJA with &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; adjustments to the provisional amounts recorded at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2017. &lt;/div&gt;Significant components of the Company&amp;#x2019;s deferred tax assets and liabilities as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;

The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating losses and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of 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 certain deferred tax assets with a valuation allowance. The Company &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;in the future determine that certain deferred tax assets more-likely-than-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;recognize a benefit from income taxes in its statement of operations in that period.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0"&gt;&lt;/div&gt; &lt;div style=" margin: 6pt 0 0; font-size: 10pt; text-indent: 0.5in"&gt;Income taxes are recorded in accordance with ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740,&lt;/div&gt;&amp;nbsp;&lt;div style="display: inline; font-style: italic;"&gt;Accounting for Income Taxes&lt;/div&gt;&amp;nbsp;(&amp;#x201c;ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740&amp;#x201d;&lt;/div&gt;), which provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. The Company determines its deferred tax assets and liabilities based on differences between financial reporting and tax bases of assets and liabilities, which are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; that some or all of the deferred tax assets will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; be realized.&lt;/div&gt; &lt;div style=" margin: 6pt 0 0; font-size: 10pt; text-indent: 0.5in"&gt;ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740&lt;/div&gt; clarifies the accounting for uncertainty in income taxes recognized in the financial statements and provides that a tax benefit from an uncertain tax position &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be recognized when it is more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. This interpretation also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods and disclosure. The Company&amp;#x2019;s policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of tax expense.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxPolicyTextBlock>

Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842&lt;/div&gt; was subsequently amended by ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;01,&lt;/div&gt; Land Easement Practical Expedient for Transition to Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842;&lt;/div&gt; ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10,&lt;/div&gt; Codification Improvements to Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842,&lt;/div&gt; Leases; and ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;11,&lt;/div&gt; Targeted Improvements. Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842,&lt;/div&gt; as amended (the "new lease standard") establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;12&lt;/div&gt; months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The effective date of the new guidance is for the Company&amp;#x2019;s &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; quarter of fiscal year &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019.&lt;/div&gt; The FASB has approved an optional, alternative method to adopt the lease standard by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company adopted the new standard effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 1, 2019, &lt;/div&gt;using the alternative method. The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have a cumulative adjustment impacting retained earnings. Adoption of the lease standard did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have a material impact on the Company&amp;#x2019;s consolidated financial statements.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 2016, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;13,&lt;/div&gt; Financial Instruments&amp;#x2014;Credit Losses (Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;326&lt;/div&gt;): Measurement of Credit Losses on Financial Instruments. This ASU requires instruments measured at amortized cost to be presented at the net amount expected to be collected. Entities are also required to record allowances for available-for-sale debt securities rather than reduce the carrying amount. On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 15, 2019, &lt;/div&gt;the FASB delayed the effective date of the standard for certain small public companies and other private companies. As amended, the effective date of ASC Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;326&lt;/div&gt; was delayed until fiscal years beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2022 &lt;/div&gt;for SEC filers that are eligible to be smaller reporting companies under the SEC&amp;#x2019;s definition, as well as private companies and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt;-for-profit entities. The Company expects that the adoption will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have a material impact on its consolidated financial statements.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&lt;div style="display: inline; background-color: white"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 2019, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;12,&lt;/div&gt; &lt;/div&gt;&lt;div style="display: inline; font-style: italic;"&gt;Income Taxes (Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740:&lt;/div&gt; Simplifying the Accounting for Income Taxes&lt;/div&gt; &lt;div style="display: inline; background-color: white"&gt;(&amp;#x201c;ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;12&amp;#x201d;&lt;/div&gt;), which removes certain exceptions to the general principles in Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740.&lt;/div&gt; ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;12&lt;/div&gt; is effective for the fiscal years beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2020, &lt;/div&gt;with early adoption permitted.

At the heart of the Company is a proprietary technical knowhow to translate natural human immunity into therapeutic product candidates.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2005,&lt;/div&gt; the Company began to develop a new framework for commercial manufacturing, using technology that required less capital, fewer operators and provided greater flexibility than standard industry practices.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;With the manufacturing capability to produce its True Human&lt;div style="display: inline; bottom:.33em; font-size: 82%; position: relative; vertical-align: baseline;"&gt;&amp;#x2122;&lt;/div&gt; antibody therapy, in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2010,&lt;/div&gt; the Company began a clinical trial program. The &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; clinical trial program at MD Anderson Cancer Center began treating the sickest cancer patients irrespective of tumor type. Soon thereafter, the Company used the same antibody therapy in various clinical studies at treatment centers around the United States (U.S.) and abroad to investigate the antibody effect in patients that had vascular disease, leukemia, type &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2&lt;/div&gt; diabetes, psoriasis or acne.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;The Company continues to be subject to a number of risks common to companies in similar stages of development. Principal among these risks are the uncertainties of technological innovations, dependence on key individuals, development of the same or similar technological innovations by the Company&amp;#x2019;s competitors and protection of proprietary technology. 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. The Company believes that its cash and cash equivalents of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$714.6&lt;/div&gt; million at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;31,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019,&lt;/div&gt; will enable the Company to achieve several major inflection points, including potential new clinical studies with our lead product candidate. We expect to have sufficient cash through &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year from the report issuance date.&lt;/div&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;718,&lt;/div&gt; which 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. The Company accounts for forfeitures as they occur rather than on an estimated basis.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt;

Actual results could differ from those estimates.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;Prior to its initial public offering on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 15, 2015, &lt;/div&gt;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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;third&lt;/div&gt; parties and external market conditions affecting the biotechnology industry sector. After the initial public offering, the fair market value is calculated by using the closing price of the Company&amp;#x2019;s common stock as reported by NASDAQ.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 51; Value: 2 --&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&lt;/div&gt;&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; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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 clinical trial research services, the costs of laboratory consumables, 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; alternative future use are expensed as incurred as research and development costs.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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=" margin: 0pt 0; font-size: 10pt"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Income Taxes &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 6pt 0 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 full fiscal year. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating losses and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of 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 certain deferred tax assets with a valuation allowance. The Company &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;in the future determine that certain deferred tax assets more-likely-than-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;recognize a benefit from income taxes in its statement of operations in that period.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0"&gt;&lt;/div&gt; &lt;div style=" margin: 6pt 0 0; font-size: 10pt; text-indent: 0.5in"&gt;Income taxes are recorded in accordance with ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740,&lt;/div&gt;&amp;nbsp;&lt;div style="display: inline; font-style: italic;"&gt;Accounting for Income Taxes&lt;/div&gt;&amp;nbsp;(&amp;#x201c;ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740&amp;#x201d;&lt;/div&gt;), which provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. The Company determines its deferred tax assets and liabilities based on differences between financial reporting and tax bases of assets and liabilities, which are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are provided if based upon the weight of available evidence, it is more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; that some or all of the deferred tax assets will &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; be realized.&lt;/div&gt; &lt;div style=" margin: 6pt 0 0; font-size: 10pt; text-indent: 0.5in"&gt;ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;740&lt;/div&gt; clarifies the accounting for uncertainty in income taxes recognized in the financial statements and provides that a tax benefit from an uncertain tax position &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be recognized when it is more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. This interpretation also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods and disclosure. The Company&amp;#x2019;s policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of tax expense.&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; 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; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;The Company accounts for its share-based compensation awards in accordance with ASC Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;718,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Compensation-Stock Compensation&lt;/div&gt; (&amp;#x201c;ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;718&amp;#x201d;&lt;/div&gt;). ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;718,&lt;/div&gt; which 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. The Company accounts for forfeitures as they occur rather than on an estimated basis.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0;

margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;The Company considers highly liquid investments with a maturity of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;90&lt;/div&gt; days 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=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; financial institution.

Upon retirement or sale, the cost of the disposed asset and the related accumulated depreciation are removed from the accounts and the resulting gain or loss is recognized.&lt;/div&gt; &lt;div style=" font-size: 10pt; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Impairment of Long-Lived Assets &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;The Company periodically evaluates its long-lived assets for potential impairment in accordance with ASC Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;360,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;Property, Plant and Equipment&lt;/div&gt;. Potential impairment is assessed when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; 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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; recognized any impairment through &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2019.&lt;/div&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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 date, 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;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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;Comprehensive Income (Loss)&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;ASC Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;220,&lt;/div&gt; &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=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;!-- Field: Page; Sequence: 54; Value: 2 --&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt"&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; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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 &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; operating segment.

Diluted EPS is computed by dividing net income/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=" margin: 0pt 0; font-size: 10pt"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Subsequent Events &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&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.

Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842&lt;/div&gt; was subsequently amended by ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;01,&lt;/div&gt; Land Easement Practical Expedient for Transition to Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842;&lt;/div&gt; ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10,&lt;/div&gt; Codification Improvements to Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842,&lt;/div&gt; Leases; and ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2018&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;11,&lt;/div&gt; Targeted Improvements. Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;842,&lt;/div&gt; as amended (the "new lease standard") establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;12&lt;/div&gt; months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The effective date of the new guidance is for the Company&amp;#x2019;s &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; quarter of fiscal year &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019.&lt;/div&gt; The FASB has approved an optional, alternative method to adopt the lease standard by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company adopted the new standard effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 1, 2019, &lt;/div&gt;using the alternative method. The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have a cumulative adjustment impacting retained earnings. Adoption of the lease standard did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have a material impact on the Company&amp;#x2019;s consolidated financial statements.&lt;/div&gt; &lt;div style=" margin: 0pt 0; font-size: 10pt; text-indent: 0.5in"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-size: 10pt; text-indent: 0.5in; margin: 0pt 0"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 2016, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;13,&lt;/div&gt; Financial Instruments&amp;#x2014;Credit Losses (Topic &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;326&lt;/div&gt;): Measurement of Credit Losses on Financial Instruments.
