On December 26, 2023, the Company announced, after extensive consideration of potential strategic alternatives, that the Board of Directors of the Company had unanimously approved, on December 19, 2023, the sale of substantially all of the Company’s assets (the “Asset Sale”) pursuant to the Asset Purchase Agreement, dated December 22, 2023, by and between the Company and Immunome Inc., and the liquidation and dissolution of the Company pursuant to a plan of complete liquidation and dissolution (the “Plan of Dissolution”), each of which, the Asset Sale and the Plan of Dissolution, is subject to the approval of the Company’s stockholders. The Company filed a definitive proxy statement on Schedule 14A with the SEC on February 23, 2024 with respect to a special meeting of the Company’s stockholders, which was convened on March 28, 2024 but was adjourned and will reconvene on April 8, 2024, at which the Company’s stockholders will be asked to, among other items, consider and approve the Asset Sale and the Plan of Dissolution.
