1. Business and Basis of Presentation
GTx, Inc. (“GTx” or the “Company”), a Delaware corporation incorporated on September 24, 1997 and headquartered in Memphis, Tennessee, is a biopharmaceutical company dedicated to the discovery, development and commercialization of medicines to treat serious and/or significant unmet medical conditions, including stress urinary incontinence and prostate cancer.
The Company is developing selective androgen receptor modulators (“SARMs”), including its lead product candidate, enobosarm (GTx-024). SARMs are a class of drugs that the Company believes has the potential to treat serious medical conditions where unmet medical needs in muscle-related diseases may benefit from increasing muscle mass, such as stress urinary incontinence (“SUI”).
In 2016, the Company initiated a Phase 2 open-label, non-placebo controlled, proof-of-concept clinical trial of enobosarm to treat postmenopausal women with SUI. Based on the results from this proof-of-concept clinical trial, the Company initiated in the third quarter of 2017 a randomized, placebo-controlled Phase 2 clinical trial to evaluate the change in the mean number of daily SUI episodes following 12 weeks of enobosarm treatment. This trial is evaluating the safety and efficacy of enobosarm (1 mg and 3 mg) compared with placebo in postmenopausal women who have demonstrated SUI symptoms for more than six months, with an average of 3 to 15 reported SUI episodes per day over a three-day period, and a positive bladder stress test. The primary endpoint for the clinical trial is the percentage of patients with at least a 50 percent reduction in mean leaks per day at week 12, compared to baseline. The trial has completed enrollment of 493 women and the Company expects top-line data early in the fourth quarter of 2018.
The Company previously announced that enobosarm achieved the pre-specified primary efficacy endpoint in both dose cohorts of the Phase 2 clinical trial designed to evaluate the efficacy and safety of a 9 mg and 18 mg dose of enobosarm in patients whose advanced breast cancer is both estrogen receptor (“ER”) positive and androgen receptor (“AR”) positive. After evaluating the breast cancer environment where the treatment paradigms are shifting to immunotherapies and/or combination therapies, the Company has decided that the time and cost of conducting the necessary clinical trials for potential approval in this indication does not warrant further development of enobosarm in this indication at this time.
In 2015, the Company entered into an exclusive license agreement with the University of Tennessee Research Foundation (“UTRF”) to develop UTRF’s proprietary selective androgen receptor degrader (“SARD”) technology which may have the potential to provide compounds that can degrade multiple forms of AR to treat those patients who do not respond or are resistant to current therapies by inhibiting tumor growth in patients with progressive castration-resistant prostate cancer (“CRPC”). The Company has ongoing mechanistic preclinical studies to select the most appropriate SARD compound to potentially move into a first-in-human clinical trial.
The Company’s ability to pursue the continued development of SARMs and its SARD program is contingent upon the Company’s ability to obtain additional funding. Accordingly, the Company is actively seeking additional funds through potential collaborative, partnering or other strategic arrangements to provide the Company with the necessary resources for the development of enobosarm and its other SARM compounds, as well as its SARD technology.
During the three months ended June 30, 2018, the Company sold 1,501,501 shares of common stock under the At-the-Market Equity OfferingSM Sales Agreement (the “ATM Sales Agreement”) with Stifel, Nicolaus & Company, Incorporated, as sales agent (“Stifel”) for net proceeds of $24,474.
Basis of Presentation
The accompanying unaudited condensed financial statements reflect, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of GTx’s financial position, results of operations and cash flows for each period presented in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted from the accompanying condensed financial statements. These interim condensed financial statements should be read in conjunction with the audited financial statements and related notes thereto, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 13, 2018. Operating results for the three and six months ended June 30, 2018 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 31, 2018.
Use of Estimates
The preparation of condensed financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual amounts and results could differ from those estimates.
Fair Value of Financial Instruments
The carrying amounts of the Company’s financial instruments (which include cash, cash equivalents, short-term investments, and accounts payable) approximate their fair values. The Company’s financial assets and liabilities are classified within a three-level fair value hierarchy that prioritizes the inputs used to measure fair value, which is defined as follows:
Level 1 — Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date
Level 2 — Inputs other than quoted prices in active markets that are observable for the asset or liability, either directly or indirectly
Level 3 — Inputs that are unobservable for the asset or liability
As the Company has the positive intent and ability to hold its certificates of deposit classified as short-term investments until maturity, these investments have been classified as held to maturity investments and are stated at cost, which approximates fair value. The Company considers these to be Level 2 investments as the fair values of these investments are determined using third-party pricing sources, which generally utilize observable inputs, such as interest rates and maturities of similar assets.
Research and Development Expenses
Research and development expenses include, but are not limited to, the Company’s expenses for personnel, supplies, and facilities associated with research activities, screening and identification of product candidates, formulation and synthesis activities, manufacturing, preclinical studies, toxicology studies, clinical trials, regulatory and medical affairs activities, quality assurance activities and license fees. The Company expenses these costs in the period in which they are incurred. The Company estimates its liabilities for research and development expenses in order to match the recognition of expenses to the period in which the actual services are received. As such, accrued liabilities related to third party research and development activities are recognized based upon the Company’s estimate of services received and degree of completion of the services in accordance with the specific third party contract.
Cash, Cash Equivalents and Short-term Investments
The Company considers highly liquid investments with initial maturities of three months or less to be cash equivalents.
At June 30, 2018 and December 31, 2017, short-term investments consisted of Federal Deposit Insurance Corporation insured certificates of deposit with original maturities of greater than three months and less than one year.
Income Taxes
The Company accounts for deferred taxes by recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Accordingly, at June 30, 2018 and December 31, 2017, net of the valuation allowance, the net deferred tax assets were reduced to zero. Income taxes are described more fully in Note 8 to the Company’s financial statements included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 13, 2018.
Other Income, net
Other income, net consists of foreign currency transaction gains and losses, interest earned on the Company’s cash, cash equivalents and short-term investments, and other non-operating income or expense.
Recent Accounting Pronouncements
In February 2016, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) 2016-02, Leases (Topic 842). This ASU requires that lessees recognize assets and liabilities on the balance sheet for the present value of the rights and obligations created by all leases with terms of more than 12 months. The ASU also will require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. This new guidance will be effective for the Company as of January 1, 2019. The Company does not expect the adoption of the standard update to have a significant impact on its financial position or results of operations.
Subsequent Events
The Company has evaluated all events or transactions that occurred after June 30, 2018 up through the date the condensed financial statements were issued. There were no material recognizable or nonrecognizable subsequent events during the period evaluated.

| Share-Based Compensation |
2. Share-Based Compensation
Share-based payments include stock option grants and RSUs under the Company’s stock option and equity incentive plans and deferred compensation arrangements for the Company’s non-employee directors. The Company recognizes compensation expense for its share-based payments based on the fair value of the awards over the period during which an employee or non-employee director is required to provide service in exchange for the award. The Company’s share-based compensation plans are described more fully in Note 3 to the Company’s financial statements included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 13, 2018.
The following table summarizes share-based compensation expense included within the condensed statements of operations for the three and six months ended June 30, 2018 and 2017:
Share-based compensation expense recorded as general and administrative expense for the three months ended June 30, 2018 and 2017 included share-based compensation expense related to deferred compensation arrangements for the Company’s non-employee directors of $41 and $42, respectively. Share-based compensation expense recorded as general and administrative expense for both the six months ended June 30, 2018 and 2017 included share-based compensation expense related to deferred compensation arrangements for the Company’s non-employee directors of $83.
The Company uses the Black-Scholes Model to value stock options. The expected life of options is determined by calculating the average of the vesting term and the contractual term of the options. The expected price volatility is based on the Company’s historical stock price volatility. The risk-free interest rate is determined using U.S. Treasury rates where the term is consistent with the expected life of the stock options. Expected dividend yield is not considered as the Company has not made any dividend payments and has no plans of doing so in the foreseeable future.
The fair value of options granted was estimated using the following assumptions for the periods presented:
The following is a summary of stock option transactions for all of the Company’s stock option and equity incentive plans since the Company’s most recent fiscal year end:
The Company estimates the fair value of RSUs using the closing price of its stock on the grant date. The fair value of RSUs is amortized on a straight-line basis over the requisite service period of the awards.
The following is a summary of the RSU transactions for all of the Company’s equity incentive plans since the Company’s most recent fiscal year end:

3. Basic and Diluted Net Loss Per Share
Basic and diluted net income (loss) per share attributable to common stockholders is calculated based on the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share gives effect to the dilutive potential of common stock consisting of stock options, unvested RSUs and common stock warrants.
Weighted average potential shares of common stock of 10,971,072 and 8,720,616 for the three months ended June 30, 2018 and 2017, respectively, and 11,414,458 and 8,490,229 for the six months ended June 30, 2018 and 2017, respectively, were excluded from the calculations of diluted net loss per share as inclusion of the potential shares would have had an anti-dilutive effect on the net loss per share for the periods.

4.Stockholders’ Equity
On February 9, 2018, the Company entered into the ATM Sales Agreement with Stifel, pursuant to which the Company may offer and sell, from time to time, through Stifel, shares of the Company’s common stock, having an aggregate offering price of up to $50,000. During the three months ended June 30, 2018, the Company sold 1,501,501 shares of common stock under the ATM Sales Agreement for net proceeds of $24,474. As of June 30, 2018, the Company had approximately $25,000 of common stock remaining available to be sold under the ATM Sales Agreement.
On September 29, 2017, the Company completed a private placement of units consisting of an aggregate of 5,483,320 shares of common stock and warrants to purchase an aggregate of 3,289,988 shares of its common stock for net proceeds of $45,648, after deducting placement agent fees and other offering expenses. The purchasers in the registered direct offering consisted solely of accredited investors that included certain institutional and existing stockholders, including a member of the Company’s board of directors. The warrants, which have five year terms expiring on September 29, 2022, are immediately exercisable and have a per share exercise price of $9.02. The Company assessed whether the warrants require accounting as derivatives. The Company determined that the warrants were indexed to the Company’s own stock. As such, the Company has concluded the warrants meet the scope exception for determining whether the instruments require accounting as derivatives and are classified in stockholders’ equity. The fair value of the warrants was estimated at $21,069 using the Black-Scholes Model with the following assumptions: expected volatility of 97%, risk free interest rate of 1.92%, expected life of five years and no dividends. The net proceeds from the private placement were allocated to the common stock and warrants based upon their relative fair values.
On November 14, 2014, the Company completed a private placement of units consisting of an aggregate of 6,431,111 shares of common stock and warrants to purchase an aggregate of 6,430,948 shares of its common stock for net proceeds of $42,814, after deducting offering expenses. The net proceeds from the private placement were allocated to the common stock and warrants based upon the fair value method. Similarly, the offering expenses were allocated between the common stock and warrants with the portion allocated to common stock offset against the proceeds allocated to stockholders’ equity, whereas the portion allocated to the warrants was expensed immediately. The warrants have a per share exercise price of $8.50, became exercisable on May 6, 2015 and will continue to be exercisable for four years thereafter. In March 2018, certain holders of warrants issued in November 2014 exercised warrants covering 1,111,082 shares of common stock in a cashless exercise for which the Company issued an aggregate of 674,579 shares of common stock upon exercise.

| Basis of Presentation | Basis of Presentation
The accompanying unaudited condensed financial statements reflect, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of GTx’s financial position, results of operations and cash flows for each period presented in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted from the accompanying condensed financial statements. These interim condensed financial statements should be read in conjunction with the audited financial statements and related notes thereto, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 13, 2018. Operating results for the three and six months ended June 30, 2018 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 31, 2018.
|
| Use of Estimates | Use of Estimates
The preparation of condensed financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual amounts and results could differ from those estimates.
|
| Fair Value of Financial Instruments |
Fair Value of Financial Instruments
The carrying amounts of the Company’s financial instruments (which include cash, cash equivalents, short-term investments, and accounts payable) approximate their fair values. The Company’s financial assets and liabilities are classified within a three-level fair value hierarchy that prioritizes the inputs used to measure fair value, which is defined as follows:
Level 1 — Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date
Level 2 — Inputs other than quoted prices in active markets that are observable for the asset or liability, either directly or indirectly
Level 3 — Inputs that are unobservable for the asset or liability
As the Company has the positive intent and ability to hold its certificates of deposit classified as short-term investments until maturity, these investments have been classified as held to maturity investments and are stated at cost, which approximates fair value. The Company considers these to be Level 2 investments as the fair values of these investments are determined using third-party pricing sources, which generally utilize observable inputs, such as interest rates and maturities of similar assets.
|
| Research and Development Expenses |
Research and Development Expenses
Research and development expenses include, but are not limited to, the Company’s expenses for personnel, supplies, and facilities associated with research activities, screening and identification of product candidates, formulation and synthesis activities, manufacturing, preclinical studies, toxicology studies, clinical trials, regulatory and medical affairs activities, quality assurance activities and license fees. The Company expenses these costs in the period in which they are incurred. The Company estimates its liabilities for research and development expenses in order to match the recognition of expenses to the period in which the actual services are received. As such, accrued liabilities related to third party research and development activities are recognized based upon the Company’s estimate of services received and degree of completion of the services in accordance with the specific third party contract.
|
| Cash, Cash Equivalents and Short-term Investments |
Cash, Cash Equivalents and Short-term Investments
The Company considers highly liquid investments with initial maturities of three months or less to be cash equivalents.
At June 30, 2018 and December 31, 2017, short-term investments consisted of Federal Deposit Insurance Corporation insured certificates of deposit with original maturities of greater than three months and less than one year.
|
| Income Taxes |
Income Taxes
The Company accounts for deferred taxes by recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Accordingly, at June 30, 2018 and December 31, 2017, net of the valuation allowance, the net deferred tax assets were reduced to zero. Income taxes are described more fully in Note 8 to the Company’s financial statements included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 13, 2018.
