The Company&#x2019;s lead compound, &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;MGL-3196&lt;/div&gt; (resmetirom), is being advanced for &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-alcoholic&lt;/div&gt; steatohepatitis (&#x201c;NASH&#x201d;), a liver disease that commonly affects people with metabolic diseases such as obesity and diabetes, and &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-alcoholic&lt;/div&gt; fatty liver disease (&#x201c;NAFLD&#x201d;).

Both Phase 2 studies were fully enrolled in 2017, the HeFH study was completed in February&#160;2018, and the NASH study was completed in May&#160;2018.

Accordingly, the unaudited condensed consolidated financial statements do not include all information and footnotes required by GAAP for complete annual financial statements. However, we believe that the disclosures included in these financial statements are adequate to make the information presented not misleading.

The interim results are not necessarily indicative of the results that we will have for the full year ending December&#160;31, 2019 or any subsequent period.

The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. Changes in estimates are recorded in the period in which they become known. Actual results could &#x200b;&#x200b;&#x200b;&#x200b;&#x200b;&#x200b;&#x200b;differ from those estimates. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0px;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Cash and Cash Equivalents &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company maintains its cash in bank accounts, the balance of which, at times, exceeds Federal Deposit Insurance Corporation insured limits. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The primary objective of the Company&#x2019;s investment activities is to preserve its capital for the purpose of funding operations and the Company does not enter into investments for trading or speculative purposes. The Company&#x2019;s cash is deposited in highly rated financial institutions in the United States. The Company invests in money market funds and high-grade, commercial paper and corporate bonds, which management believes are subject to minimal credit and market risk. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 0pt; margin-bottom: 0pt; line-height: 12pt;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Marketable Securities &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;Marketable securities consist of investments in high-grade corporate obligations and government and government agency obligations that are classified as &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;available-for-sale.&lt;/div&gt; Since these securities are available to fund current operations, they are classified as current assets on the consolidated balance sheets.&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;The Company adjusts the cost of &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;available-for-sale&lt;/div&gt; debt securities for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion as a component of interest income, net. Realized gains and losses and declines in value, if any, that the Company judges to be other-than-temporary on &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;available-for-sale&lt;/div&gt; securities are reported as a component of interest income, net. To determine whether an other-than-temporary impairment exists, the Company considers whether it intends to sell the debt security and, if the Company does not intend to sell the debt security, it considers available evidence to assess whether it is more likely than not that it will be required to sell the security before the recovery of its amortized cost basis. During the three and nine months ended September&#160;30, 2019 and 2018, the Company determined it did not have any securities that were other-than-temporarily impaired.&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Marketable securities are stated at fair value, including accrued interest, with their unrealized gains and losses included as a component of accumulated other comprehensive income or loss, which is a separate component of stockholders&#x2019; equity. The fair value of these securities is based on quoted prices and observable inputs on a recurring basis. Realized gains and losses are determined on the specific identification method. During the three and nine months ended September&#160;30, 2019 and 2018, the Company did not have any realized gains or losses on marketable securities. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0px;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Fair Value of Financial Instruments &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The carrying amounts of the Company&#x2019;s financial instruments, which include cash equivalents, and marketable securities, approximate their fair values. The fair value of the Company&#x2019;s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels: &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 0%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px; margin-left: 4%;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Level&#160;1&#x2014;quoted prices in active markets for identical assets and liabilities. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 0%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px; margin-left: 4%;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Level&#160;2&#x2014;observable inputs other than Level&#160;1 inputs. Examples of Level&#160;2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 0%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px; margin-left: 4%;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Level&#160;3&#x2014;unobservable inputs that reflect the Company&#x2019;s own assumptions about the assumptions market participants would use in pricing the asset or liability. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Financial assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The Company measures the fair value of its marketable securities by taking into consideration valuations obtained from third-party pricing sources. The pricing services utilize industry standard valuation models, including both income and market based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker-dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs. As of September&#160;30, 2019, the Company&#x2019;s financial assets valued based on Level&#160;1 inputs consisted of cash and cash equivalents in a money market fund and its financial assets valued based on Level&#160;2 inputs consisted of high-grade corporate bonds and commercial paper. During the three and nine months ended September&#160;30, 2019 and 2018, the Company did not have any transfers of financial assets between Levels&#160;1 and 2. As of September&#160;30, 2019 and December&#160;31, 2018, the Company did not have any financial liabilities that were recorded at fair value on a recurring basis on the balance sheet. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0px;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Research and Development Costs &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;Research and development costs are expensed as incurred. Research and development costs are comprised of costs incurred in performing research and development activities, including internal costs (including stock-based compensation), costs for consultants, milestone payments under licensing agreements, and other costs associated with the Company&#x2019;s preclinical and clinical programs. In particular, the Company has conducted safety studies in animals, optimized and implemented the manufacturing of our drug, and conducted Phase &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;1-3&lt;/div&gt; clinical trials, all of which are considered research and development expenditures. Significant judgment and estimates are made in determining the amount of research and development costs recognized in each reporting period. The Company analyzes the progress of its clinical trials, completion of milestones under its license agreements, invoices received and contracted costs when estimating research and development costs. Actual results could differ from the Company&#x2019;s estimates. The Company&#x2019;s historical estimates for research and development costs have not been materially different from the actual costs.&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Patents &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Costs to secure and defend patents are expensed as incurred and are classified as general and administrative expense in the Company&#x2019;s consolidated statements of operations. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0px;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Stock-Based Compensation &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;The Company recognizes stock-based compensation expense based on the grant date fair value of stock options granted to employees, officers, and directors. The Company uses the Black-Scholes option pricing model to determine the grant date fair value as management believes it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options. Expected volatility is based upon an industry estimate or blended rate including the Company&#x2019;s historical trading activity. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The Company estimates the forfeiture rate based on historical data. This analysis is &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;re-evaluated&lt;/div&gt; at least annually and the forfeiture rate is adjusted as necessary.&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Certain of the employee stock options granted by the Company are structured to qualify as incentive stock options (&#x201c;ISOs&#x201d;). Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize the related deferred tax assets. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0px;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Income Taxes &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company uses the asset and liability method to account for income taxes. Deferred tax assets and liabilities are determined based on the expected future tax consequences of temporary differences between the Company&#x2019;s financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates expected to be in effect in the years in which the differences are expected to reverse. The Company currently maintains a 100% valuation allowance on its deferred tax assets. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0px;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Comprehensive Loss &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-owner&lt;/div&gt; sources. Changes in unrealized gains and losses on marketable securities represent the only difference between the Company&#x2019;s net loss and comprehensive loss.&lt;/div&gt;&lt;div style="text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-weight: normal; margin-top: 18pt; margin-bottom: 0px;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Basic and Diluted Loss Per Common Share &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Basic net loss per share is computed using the weighted average number of common shares outstanding during the period, excluding restricted stock that has been issued but is not yet vested. Diluted net loss per common share is computed using the weighted average number of common shares outstanding and the weighted average dilutive potential common shares outstanding using the treasury stock method. However, for the nine months ended September&#160;30, 2019 and 2018, diluted net loss per share is the same as basic net loss per share because the inclusion of weighted average shares of unvested restricted common stock, common stock issuable upon the exercise of stock options, and common stock issuable upon the conversion of preferred stock would be anti-dilutive. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The following table summarizes outstanding securities not included in the computation of diluted net loss per common share, as their inclusion would be anti-dilutive: &lt;/div&gt;&lt;/div&gt;

A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application.&#160;The Company adopted ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2016-02&lt;/div&gt; effective January&#160;1, 2019.&#160;There was no significant retrospective impact from the adoption.&#160;The new standard provides a number of optional practical expedients in transition. We have elected the package of practical expedients, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The new standard also provides practical expedients for an entity&#x2019;s ongoing accounting. We have elected the short-term lease exception and we will not recognize ROU assets or lease liabilities for qualifying leases (leases with a term of less than 12 months from lease commencement).&#160;In 2019, the Company accounted for a new lease under the guidance (see Note &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;8&lt;/div&gt;).&lt;/div&gt;</us-gaap:OrganizationConsolidationBasisOfPresentationBusinessDescriptionAndAccountingPoliciesTextBlock>

The Company includes such amortization and accretion as a component of interest income, net.

The fair value of these securities is based on quoted prices and observable inputs on a recurring basis. Realized gains and losses are determined on the specific identification method.

The fair value of the Company&#x2019;s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels: &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 0%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px; margin-left: 4%;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Level&#160;1&#x2014;quoted prices in active markets for identical assets and liabilities. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 0%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0px; margin-left: 4%;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Level&#160;2&#x2014;observable inputs other than Level&#160;1 inputs.

The Company measures the fair value of its marketable securities by taking into consideration valuations obtained from third-party pricing sources. The pricing services utilize industry standard valuation models, including both income and market based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker-dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs. As of September&#160;30, 2019, the Company&#x2019;s financial assets valued based on Level&#160;1 inputs consisted of cash and cash equivalents in a money market fund and its financial assets valued based on Level&#160;2 inputs consisted of high-grade corporate bonds and commercial paper. During the three and nine months ended September&#160;30, 2019 and 2018, the Company did not have any transfers of financial assets between Levels&#160;1 and 2. As of September&#160;30, 2019 and December&#160;31, 2018, the Company did not have any financial liabilities that were recorded at fair value on a recurring basis on the balance sheet. &lt;/div&gt;&lt;/div&gt;</us-gaap:FairValueOfFinancialInstrumentsPolicy>

The Company uses the Black-Scholes option pricing model to determine the grant date fair value as management believes it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options. Expected volatility is based upon an industry estimate or blended rate including the Company&#x2019;s historical trading activity. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The Company estimates the forfeiture rate based on historical data. This analysis is &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;re-evaluated&lt;/div&gt; at least annually and the forfeiture rate is adjusted as necessary.&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Certain of the employee stock options granted by the Company are structured to qualify as incentive stock options (&#x201c;ISOs&#x201d;). Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize the related deferred tax assets. &lt;/div&gt;&lt;/div&gt;</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application.&#160;The Company adopted ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2016-02&lt;/div&gt; effective January&#160;1, 2019.&#160;There was no significant retrospective impact from the adoption.&#160;The new standard provides a number of optional practical expedients in transition. We have elected the package of practical expedients, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The new standard also provides practical expedients for an entity&#x2019;s ongoing accounting. We have elected the short-term lease exception and we will not recognize ROU assets or lease liabilities for qualifying leases (leases with a term of less than 12 months from lease commencement).&#160;In 2019, the Company accounted for a new lease under the guidance (see Note &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;8&lt;/div&gt;).&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Management expects to incur losses for the foreseeable future. To date, the Company has funded its operations primarily through the issuance of convertible debt, the proceeds from the Merger on July&#160;22, 2016, and proceeds from sales of the Company&#x2019;s equity securities. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company believes that its cash, cash equivalents and marketable securities at September&#160;30, 2019 will be sufficient to fund operations past one year from the issuance of these financial statements. To meet its future capital needs, the Company intends to raise additional capital through debt or equity financings, collaborations, partnerships or other strategic transactions. However, there can be no assurance that the Company will be able to complete any such transactions on acceptable terms or otherwise. The inability of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company&#x2019;s business, results of operations and financial condition. The Company has the ability to delay certain research activities and related clinical expenses if necessary due to liquidity concerns until a date when those concerns are relieved. &lt;/div&gt;&lt;/div&gt;</us-gaap:SubstantialDoubtAboutGoingConcernTextBlock>

We ceased making new awards under the 2006 Stock Plan upon adoption of the 2015 Stock Plan. The 2015 Stock Plan provides for the grant of incentive stock options, &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-statutory&lt;/div&gt; stock options, restricted stock and other stock-based compensation awards to employees, officers, directors, and consultants of the Company. The administration of the 2015 Stock Plan is under the general supervision of the Compensation Committee of the Board of Directors. The terms of stock options awarded under the 2015 Stock Plan, in general, are determined by the Compensation Committee, provided the exercise price per share generally shall not be set at less than the fair market value of a share of the common&#160;stock on the date of grant and the term shall not be greater than ten years from the date the option is granted. As of September&#160;30, 2019, the Company had options outstanding to purchase 1,461,237 shares of its common stock, which includes options outstanding under its 2006 Stock Plan.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. The lease term is determined to be the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-cancelable&lt;/div&gt; period including any lessee renewal options that are considered reasonably certain of exercise. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company used judgment to determine an appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term in a similar economic environment.&lt;/div&gt; &lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Future minimum payments under the Company&#x2019;s operating leases related to the ROU asset and lease liability as of September&#160;30, 2019 was as follows (in thousand): &lt;/div&gt;&lt;/div&gt;

A single-digit royalty payment range is based on net sales of products developed from resmetirom, subject to certain reductions. Except as described above, the Company has not achieved any additional product development or regulatory milestones and had no Licensed Product sales for the nine months ended September&#160;30, 2019 and 2018.&lt;/div&gt; &lt;div style="text-align: left; text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company has entered into customary contractual arrangements and letters of intent in preparation for and in support of the Phase 3 clinical trials. &lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>
