Item 8.01 Other Events.

On May 8, 2019, GTx, Inc. (“GTx”) filed with the U.S. Securities and Exchange Commission (the “SEC”) a proxy statement/prospectus/information statement (the “Joint Proxy Statement”) relating to the Agreement and Plan of Merger and Reorganization, dated March 6, 2019, as amended by Amendment No. 1 to Agreement and Plan of Merger and Reorganization dated April 30, 2019 (together, the “Merger Agreement”), by and among GTx, Grizzly Merger Sub, Inc., a wholly-owned subsidiary of GTx, and Oncternal Therapeutics, Inc. (“Oncternal”) pursuant to which a wholly-owned subsidiary of GTx will merge with and into Oncternal, with Oncternal surviving as a wholly-owned subsidiary of GTx (the “Merger”).

Between April 10, 2019 and May 7, 2019, six purported stockholder class action lawsuits (the “Lawsuits”) were filed, naming as defendants GTx and GTx’s board of directors. Collectively, these lawsuits allege, among other things, violations of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as well as Rule 14a-9 promulgated thereunder, in connection with GTx’s filing of the Registration Statement on Form S-4 of which the Joint Proxy Statement is a part with the SEC. As relief, the Lawsuits each separately seek an order, among other things, enjoining the defendants from closing the proposed transaction or taking any steps to consummate the Merger and/or awarding rescissory damages. The defendants specifically deny all allegations in the Lawsuits, including that any additional disclosure was or is required and intend to defend the Lawsuits vigorously. However, GTx wishes to make the following supplemental disclosures relating to the Merger, which supplemental disclosures are set forth below (the “Supplemental Disclosures”), solely for the purpose of mooting the allegations contained in the Lawsuits and avoiding the expense and burden of litigation. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the Supplemental Disclosures set forth herein.

Important information concerning the Merger and the transactions contemplated by the Merger Agreement is set forth in the Joint Proxy Statement. The Joint Proxy Statement is amended and supplemented by, and should be read as part of, and in conjunction with, the Supplemental Disclosures set forth in this Current Report on Form 8-K.

Supplemental Disclosures

The following supplemental information should be read in conjunction with the Joint Proxy Statement, which should be read in its entirety. Defined terms used but not defined herein have the meanings set forth in the Joint Proxy Statement, and all page references refer to pages of the Joint Proxy Statement.

The following disclosure replaces the third full paragraph on page 125 of the Joint Proxy Statement. The modified text is underlined and bolded below:

On October 1, 2018, Mr. Hanover was introduced by telephone to the chief executive officer of Company D, a holding company for various subsidiaries, including a subsidiary developing selective estrogen receptor degraders (“SERD”) compounds. The chief executive officer of Company D expressed an interest in merging his SERD program with GTx’s SARD technology and suggested that the companies enter into a mutual confidentiality agreement for the exchange of information, which was done on October 2, 2018. Neither this confidentiality agreement, nor any other confidentiality agreements to be entered into with potential acquirers contained a standstill provision.

The following disclosure replaces the fourth full paragraph on page 129 of the Joint Proxy Statement. The modified text is underlined and bolded below:

In December 12, 2018, the GTx Board held a special meeting, with GTx senior management attending, for the purpose of receiving an update from Dr. Wills and Mr. Hanover on their discussions with various parties interested in some form of a potential business transaction with GTx. Mr. Hanover reported that discussions with Company D were ongoing over the last several weeks but were becoming more protracted and complex, and he was unsure whether GTx senior management would be making a favorable recommendation to the GTx Board about pursuing that transaction. Mr. Hanover explained that the complexity of trying to merge GTx’s SARD technology with Company D’s SERD program under the umbrella of a holding company controlled by Company D would make it difficult for GTx shareholders to have any liquidity in this investment and the equity split being suggested for GTx shareholders was inadequate. Dr. Wills reported that discussions with Company L continued to be positive but their proposed equity split for a combined company (which was 90% for Company L’s stockholders and 10% for GTx’s stockholders) was, in his opinion, insufficient and there was little synergy in Company L’s technology and what GTx would be bringing to the combined company for development. Dr. Wills reported that while discussions with Oncternal were at an early stage, he, Mr. Hanover and Mr. Hyde had good discussions with Oncternal and there seemed to be a willingness to structure a transaction that may be more beneficial to GTx and its stockholders than other companies have been willing to offer. He noted that Oncternal was an oncology company and the synergies between the two companies were good, and that Oncternal has asked for and had been given access to GTx’s data room so it and its advisors could undertake more extensive due diligence of GTx and its technologies. Mr. Hanover reported that Company J had decided not to pursue the acquisition of SARMs, including enobosarm, although he had received some interest in the asset from Company K and would explore with Company K whether it was in a position to make a meaningful proposal for GTx’s SARMs. He also stated that GTx senior management would be exploring with Oncternal whether it wanted GTx to retain SARMs as an asset should Oncternal and GTx decide to combine.

The following disclosure replaces the fourth full paragraph on page 132 of the Joint Proxy Statement. The modified text is underlined and bolded below:

On January 11, 2019, the GTx Board held a special meeting, with GTx senior management attending, for the purpose of receiving an update from GTx senior management on its ongoing strategic discussions. Representatives from each of Aquilo and Cooley attended the meeting and participated in the discussions. Dr. Wills reported that he met with the senior executive representing Company M and learned that he and his team had a real interest in trying to reach an acceptable reverse Merger Agreement with GTx at a proposed equity split for a combined company of 80% for Company M’s stockholders and 20% for GTx’s stockholders. He indicated a willingness to consider improving the proposal if his team’s diligence did not signal any concerns on their part. Dr. Wills arranged for Mr. Hyde, himself and Mr. Hanover to meet with Company M’s senior executive the following day. Dr. Wills continued to have concerns about whether Company M’s lack of funds was one of its primary drivers of its discussion with GTx, and the dissimilarities in each company’s respective technologies made Company M less appealing from a synergistic standpoint. Lastly, Dr. Wills stated that Oncternal’s management team continued to be committed to reaching an agreement and they were currently negotiating a draft letter of intent to bring to the GTx Board for its review and approval.

The following disclosure replaces the sixth full paragraph on page 132 of the Joint Proxy Statement. The modified text is underlined and bolded below:

On January 15, 2019, GTx received an initial draft of the proposed non-binding letter of intent from Oncternal, which among other terms, included a unilateral exclusivity agreement of GTx and that the post-Closing board would consist of nine directors, with GTx being represented by two board members, with Shanghai being represented by two board members, Mr. Hale, Mr. Breitmeyer, and the three remaining directors to be designated in the definitive agreement.

The following disclosure replaces the fourth full paragraph on page 133 of the Joint Proxy Statement. The modified text is underlined and bolded below:

On January 29, 2019, a letter of intent with Oncternal was executed by both companies following the approval of each of the GTx Board and the Oncternal Board on the preceding day. Since there was an exclusivity provision contained in the letter of intent, there was no further conversation with Company M about its proposal following GTx’s execution of the letter of intent. After the letter of intent was executed by both companies, Mr. Hale discussed the post-Closing board composition with Dr. Wills. Mr. Hale recommended that Dr. Wills and Mr. Carter should serve as the GTx’s board designees given they both had pharmaceutical and/or biotech experience, had previously served on public company boards, and were familiar with GTx’s clinical programs.

The following disclosure replaces the sixth full paragraph on page 134 of the Joint Proxy Statement. The modified text is underlined and bolded below:

On February 15, 2019, Latham sent Cooley a revised draft of the Original Merger Agreement, which indicated that Rob Wills and Michael Carter would serve as the GTx’s board designees on the post-Closing board. Latham also sent Cooley a revised draft of GTx’s disclosure schedules.

The following disclosure replaces the fifth full paragraph on page 147 of the Joint Proxy Statement. The modified text is underlined and bolded below and the charts set forth below are also supplements to the original disclosure in the Joint Proxy Statement:
