(\u201cGalera\u201d) (OTC: GRTX), a clinical-stage biopharmaceutical company focused on advancing a pan-NOS inhibitor through clinical development for patients with the hardest-to-treat forms of advanced breast cancer, and Obsidian Therapeutics, Inc.\u00a0(\u201cObsidian\u201d), a privately-held clinical-stage biopharmaceutical company harnessing\u00a0novel protein-regulation technology to develop engineered tumor infiltrating lymphocyte, (\u201cTIL\u201d), cell therapies, today announced that they have entered into a definitive merger agreement to combine in an all-stock transaction. The combination will be accomplished by both companies becoming wholly owned subsidiaries of a newly formed company. Upon completion of the transaction, the combined company plans to operate under the name\u00a0Obsidian Therapeutics, Inc. and will apply to trade on Nasdaq under the ticker symbol \u201cOBX.\u201d<\/p>\n<p align=\"justify\">In support of the transaction, Galera and Obsidian have secured commitments for an oversubscribed private placement financing that is expected to result in total gross proceeds of $350 million from a syndicate of new investors, including Balyasny Asset Management, Caligan Partners LP, Eventide Asset Management, Nantahala Capital, Octagon Capital, Redmile, Spruce Street Capital and Trails Edge Capital Partners, and with participation from current Obsidian investors, including Atlas Venture, Deep Track Capital, Foresite Capital, Janus Henderson Investors, Logos Capital, Novo Holdings A\/S, Paradigm BioCapital Advisors, Pivotal bioVenture Partners, RA Capital Management, RTW Investments, TCGX and Wellington Management, among other leading investment management firms.<\/p>\n<p align=\"justify\">The private placement financing is expected to close immediately prior to completion of the proposed merger transaction. The combined company\u2019s cash and cash equivalents balance at closing, including the funds from the private placement financing, is anticipated to fund the combined company\u2019s operations into the second half of 2028 and provides runway through key clinical milestones for Obsidian\u2019s lead product candidate, OBX-115. These include Phase 1 data from the ongoing NSCLC trial expected in the first half of 2027, and by year-end 2027, topline data from their melanoma registration-enabling trial. The combined company will also continue to support Galera\u2019s pipeline.<\/p>\n<p align=\"justify\">\u201cAt Obsidian, we are striving to deliver a best-in-class TIL cell therapy developed using our proprietary protein-regulation technology,\u201d said Madan Jagasia, M.D., Chief Executive Officer of Obsidian. \u201cWe believe OBX-115 offers an opportunity to provide patients with an improved TIL product and patient experience. This transaction and the support from leading life sciences investors will allow us to advance our development plans for OBX-115 in melanoma and NSCLC.\u201d<\/p>\n<p align=\"justify\">Obsidian leverages their cytoDRIVE\u2122 platform to develop engineered TIL cell therapies. OBX-115 is currently in a Phase 2 clinical trial for the treatment of advanced melanoma and a Phase 1 clinical trial for the treatment of NSCLC. OBX-115 is designed with regulatable membrane-bound IL15 (mbIL15), which drives TIL persistence,\u00a0eliminates\u00a0the need to dose toxic interleukin-2 (IL2), and enables outpatient administration of low-dose lymphodepletion. Furthermore, OBX-115 can be manufactured using tumor tissue procurement from an outpatient, minimally invasive core needle biopsy. OBX-115 has been granted Fast Track and Regenerative Medicine Advanced Therapy designations from the U.S. Food and Drug Administration for the treatment of patients with unresectable or metastatic melanoma that is resistant to immune checkpoint inhibitor therapy.<\/p>\n<p align=\"justify\">\u201cWe believe this transaction with Obsidian is the best path forward for Galera and look forward to the combined company\u2019s success,\u201d said J. Mel Sorensen, M.D., Chief Executive Officer of Galera. \u201cObsidian\u2019s pipeline of novel engineered TIL cell therapies and its promising lead product candidate, OBX-115, offer near-term, value creating milestones for Galera stockholders. In addition, Galera stockholders will retain a contingent value right for 95% of all future milestones for up to 10 years arising out of its October 2025 Asset Purchase Agreement with Biossil.ai for its dismutase mimetics.\u201d<\/p>\n<p align=\"justify\">\n        <strong>About the Proposed Transaction<\/strong>\n      <\/p>\n<p align=\"justify\">Under the terms of the merger agreement, as of the closing of the proposed transaction, the pre-closing Galera stockholders (other than those investors participating in the private placement financing) are expected to own approximately 1.8% of the combined company, the pre-closing Obsidian stockholders are expected to own approximately 53.2% of the combined company, and investors in the private placement financing are expected to own approximately 45.0% of the combined company. The percentage of the combined company that Galera\u2019s stockholders will own as of the closing of the proposed transaction is subject to adjustment based on the estimated amount of Galera\u2019s net cash immediately prior to the closing date.<\/p>\n<p align=\"justify\">The pre-closing Galera stockholders (other than those investors participating in the private placement financing) are expected to receive one contingent value right for each outstanding share of Galera common stock held by such stockholder, representing the right to receive contingent payments upon the occurrence of certain events (including receipt of milestone proceeds under the Biossil.ai agreement).<\/p>\n<p align=\"justify\">The transaction has received approval by the Board of Directors of both companies and is expected to close by the third quarter of 2026, subject to certain closing conditions, including, among others, approval by the stockholders of each company, the effectiveness of a registration statement to be filed with the U.S. Securities and Exchange Commission (the \u201cSEC\u201d) to register the securities to be issued in connection with the proposed acquisitions of Obsidian and Galera and the satisfaction of other customary closing conditions.<\/p>\n<p align=\"justify\">The combined company plans to operate under the name Obsidian Therapeutics, Inc. and will be led by Madan Jagasia, M.D., Obsidian\u2019s current Chief Executive Officer.
