1. Business and Basis of Presentation
Business
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 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”) and Duchenne muscular dystrophy (“DMD”).
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 emerging data from this ongoing proof-of-concept clinical trial, the Company initiated a placebo-controlled Phase 2 clinical trial of enobosarm to treat postmenopausal women with SUI in the third quarter of 2017.
The Company commenced enrollment in 2015 in a 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. The Company announced in November 2016 that enobosarm achieved the pre-specified primary efficacy endpoint in the 9 mg dose cohort and announced in November 2017 that the pre-specified primary efficacy endpoint was also achieved in the 18 mg dose cohort. After evaluating the breast cancer environment where the treatment paradigms are shifting to immunotherapies and/or combination therapies, along with the time and cost of conducting the necessary clinical trials for approval, the Company has decided not to pursue additional clinical development of enobosarm for this indication.
The Company has also evaluated several SARM compounds, including enobosarm, in preclinical models of DMD where a SARM’s ability to increase muscle mass may prove beneficial to patients suffering from DMD. The Company is actively seeking potential collaboration partners to further develop a SARM for the treatment of DMD.
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 compound to potentially move into a first-in-human clinical trial.
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.
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 for the year ended December 31, 2016. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 31, 2017.
On December 5, 2016, the Company effected a one-for-ten reverse stock split of its common stock through an amendment to its restated certification of incorporation. As of the effective time of the reverse stock split, every ten shares of the Company’s issued and outstanding common stock were automatically combined and reclassified into one issued and outstanding share of common stock, without any change in par value per share. The amendment to the Company’s restated certification of incorporation also reduced the number of authorized shares of common stock from 400,000,000 to 60,000,000 shares. The reverse stock split affected all shares of the Company’s common stock outstanding immediately prior to the effective time of the reverse stock split. Additionally, as a result of the reverse stock split, proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all stock options, restricted stock units and warrants issued by the Company and outstanding immediately prior to the effective time, which resulted in a proportionate decrease in the number of shares of the Company’s common stock reserved for issuance upon exercise or vesting of such stock options, restricted stock units and warrants, and, in the case of stock options and warrants, a proportionate increase in the exercise price of all such stock options and warrants. In addition, the number of shares reserved for issuance under the Company’s equity compensation plans immediately prior to the effective time was reduced proportionately. No fractional shares were issued as a result of the reverse stock split. Stockholders who have otherwise been entitled to receive a fractional share received a cash payment in lieu thereof. All references to shares of common stock, all per share data, and all warrant, stock option and restricted stock unit (“RSU”) activity for all periods presented in these condensed financial statements and notes to the condensed financial statements have been adjusted to reflect the reverse stock split on a retroactive basis.
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.
Warrant Liability
In November 2014, the Company issued warrants to purchase 6,430,948 shares of its common stock. The Company classified these warrants as a liability on its balance sheet since the warrants contained certain terms that could have required the Company (or its successor) to purchase the warrants for cash in an amount equal to the value (as calculated utilizing a contractually-agreed Black-Scholes-Merton option pricing valuation model (“Black-Scholes Model”)) of the unexercised portion of the warrants in connection with certain change of control transactions occurring on or prior to December 31, 2016, with such cash payment capped at an amount equal to $1.25 per unexercised share underlying each warrant. As a result of the provision of the warrants requiring cash settlement upon certain change of control transactions, the Company was required to account for these warrants as a liability at fair value and the estimated warrant liability was required to be revalued at each balance sheet date until the earlier of the exercise of the warrants, the modification to remove the provision that could require cash settlement upon certain change of control transactions or the expiration of such provision on December 31, 2016. Effective March 25, 2016, each of the warrants was amended by agreement of the warrant holders to remove the provision that could require cash settlement upon certain change of control transactions. These warrants were no longer accounted for as a liability subsequent to March 25, 2016. The Company recorded a non-cash reclassification of the warrant fair value to stockholders’ equity based on the warrants’ fair value as of the March 25, 2016 modification date, with no further adjustments to the fair value of these warrants being required.
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 September 30, 2017 and December 31, 2016, 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 September 30, 2017 and December 31, 2016, 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 24, 2017.
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.
Loan Agreement
On August 10, 2017, the Company entered into a loan agreement with J.R. Hyde, III and The Pyramid Peak Foundation (the “Loan Agreement”) to borrow up to a total of $15,000 (the “Loans”). Each of Mr. Hyde and The Pyramid Peak Foundation (the “Lenders”) are significant stockholders, and Mr. Hyde serves on the Company’s board of directors. The Company did not borrow any amounts under the Loan Agreement and the Loan Agreement terminated in accordance with its terms on September 29, 2017 as on that date, the Company completed a private placement of its equity securities resulting in gross proceeds of $48,500 (described more fully in Note 4, Stockholders’ Equity). Under the terms of the Loan Agreement, the Loan Agreement terminated on the date that the Company consummated an equity financing resulting in gross proceeds of at least $15,000.
Subsequent Events
The Company has evaluated all events or transactions that occurred after September 30, 2017 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 24, 2017.
During the first quarter of 2017, the Company adopted the Financial Accounting Standards Board Accounting Standards Update 2016-09, Improvements to Employee Share Based Payment Accounting. This guidance addresses the income tax effects of stock-based payments and eliminates the windfall pool concept, as all of the tax effects related to stock-based payments will now be recorded at settlement (or expiration) through the income statement. The new guidance also permits entities to make an accounting policy election for the impact of forfeitures on the recognition of expense for stock-based payment awards, allowing for forfeitures to be estimated or recognized when they occur. The Company elected to prospectively adopt the policy that forfeitures be recorded when they occur. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations.
The following table summarizes share-based compensation expense included within the condensed statements of operations for the three and nine months ended September 30, 2017 and 2016:
Share-based compensation expense recorded as general and administrative expense for the three months ended September 30, 2017 and 2016 included share-based compensation expense related to deferred compensation arrangements for the Company’s non-employee directors of $41 and $33, respectively. Share-based compensation expense recorded as general and administrative expense for the nine months ended September 30, 2017 and 2016 included share-based compensation expense related to deferred compensation arrangements for the Company’s non-employee directors of $124 and $92, respectively.
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:
There were no options granted during the three months ended September 30, 2017. Options granted during the three months ended September 30, 2016 were valued using the following assumptions: expected volatility of 89.4%, risk free interest rate of 1.2%, and an expected life of six years.
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 8,741,251 and 8,151,501 for the three months ended September 30, 2017 and 2016, respectively, and 8,574,822 and 8,169,793 for the nine months ended September 30, 2017 and 2016, 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
Common Stock
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 October 14, 2016, the Company completed a registered direct offering of its common stock, in which it sold 1,728,395 shares of its common stock for net proceeds of $13,692. The purchasers in the registered direct offering consisted of certain existing GTx stockholders and certain members of the GTx management team and board of directors.
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 purchasers in the private placement included certain existing GTx stockholders and certain members of the GTx management team and board of directors. 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. Prior to May 6, 2015, each warrant was subject to net cash settlement if, at the time of any exercise, there was then an insufficient number of authorized and reserved shares of common stock to effect a share settlement of the warrant. Under the terms of the warrants, as of May 6, 2015, the net cash settlement feature of the warrants automatically became inoperative; accordingly, the warrants are exercisable only for shares of the Company’s common stock. The warrants, however, also contained certain terms that could have required the Company (or its successor) to purchase the warrants for cash in an amount equal to the value (as calculated utilizing a contractually-agreed Black-Scholes Model) of the unexercised portion of the warrants in connection with certain change of control transactions occurring on or prior to December 31, 2016, with the cash payment capped at an amount equal to $1.25 per unexercised share underlying each warrant. Due to the provision of the warrants that could have required cash settlement upon certain change of control transactions, the Company was required to account for these warrants as a liability at fair value using the Black-Scholes Model and the estimated warrant liability was required to be revalued at each balance sheet date until the earlier of the exercise of the warrants, the modification to remove the provision that could require cash settlement upon certain change of control transactions or the expiration of such provision on December 31, 2016. Effective March 25, 2016, each of the warrants was amended by agreement of the warrant holders to remove the provision that could require cash settlement upon certain change of control transactions. These warrants were no longer accounted for as a liability at March 31, 2016. The Company recorded a non-cash reclassification of the warrant fair value to stockholders’ equity based on the warrants’ fair value as of the March 25, 2016 modification date, with no further adjustments to the fair value of these warrants being required. The fair value of the warrants on the March 25, 2016 modification date of $19,186 was estimated using the Black-Scholes Model with the following assumptions: expected volatility of 101%, risk-free interest rate of 1.1%, expected life of approximately 3.1 years and no dividends. |

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 for the year ended December 31, 2016. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 31, 2017.
On December 5, 2016, the Company effected a one-for-ten reverse stock split of its common stock through an amendment to its restated certification of incorporation. As of the effective time of the reverse stock split, every ten shares of the Company’s issued and outstanding common stock were automatically combined and reclassified into one issued and outstanding share of common stock, without any change in par value per share. The amendment to the Company’s restated certification of incorporation also reduced the number of authorized shares of common stock from 400,000,000 to 60,000,000 shares. The reverse stock split affected all shares of the Company’s common stock outstanding immediately prior to the effective time of the reverse stock split. Additionally, as a result of the reverse stock split, proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all stock options, restricted stock units and warrants issued by the Company and outstanding immediately prior to the effective time, which resulted in a proportionate decrease in the number of shares of the Company’s common stock reserved for issuance upon exercise or vesting of such stock options, restricted stock units and warrants, and, in the case of stock options and warrants, a proportionate increase in the exercise price of all such stock options and warrants. In addition, the number of shares reserved for issuance under the Company’s equity compensation plans immediately prior to the effective time was reduced proportionately. No fractional shares were issued as a result of the reverse stock split. Stockholders who have otherwise been entitled to receive a fractional share received a cash payment in lieu thereof. All references to shares of common stock, all per share data, and all warrant, stock option and restricted stock unit (“RSU”) activity for all periods presented in these condensed financial statements and notes to the condensed financial statements have been adjusted to reflect the reverse stock split on a retroactive basis. |
| 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. |
| Warrant Liability |
Warrant Liability
In November 2014, the Company issued warrants to purchase 6,430,948 shares of its common stock. The Company classified these warrants as a liability on its balance sheet since the warrants contained certain terms that could have required the Company (or its successor) to purchase the warrants for cash in an amount equal to the value (as calculated utilizing a contractually-agreed Black-Scholes-Merton option pricing valuation model (“Black-Scholes Model”)) of the unexercised portion of the warrants in connection with certain change of control transactions occurring on or prior to December 31, 2016, with such cash payment capped at an amount equal to $1.25 per unexercised share underlying each warrant. As a result of the provision of the warrants requiring cash settlement upon certain change of control transactions, the Company was required to account for these warrants as a liability at fair value and the estimated warrant liability was required to be revalued at each balance sheet date until the earlier of the exercise of the warrants, the modification to remove the provision that could require cash settlement upon certain change of control transactions or the expiration of such provision on December 31, 2016. Effective March 25, 2016, each of the warrants was amended by agreement of the warrant holders to remove the provision that could require cash settlement upon certain change of control transactions. These warrants were no longer accounted for as a liability subsequent to March 25, 2016. The Company recorded a non-cash reclassification of the warrant fair value to stockholders’ equity based on the warrants’ fair value as of the March 25, 2016 modification date, with no further adjustments to the fair value of these warrants being required. |

- Definition The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
