TerSera Therapeutics will acquire Margenza (margetuximab-cmkb) from MacroGenics
MacroGenics, Inc. and TerSera Therapeutics LLC, a privately-held biopharmaceutical company with a focus in oncology and non-opioid pain management, announced that they have entered into an agreement in which TerSera will acquire global rights to Margenza (margetuximab-cmkb)
Margenza was approved by the FDA in December 2020 in combination with chemotherapy for the treatment of adult patients with metastatic HER2-positive breast cancer who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease. The approval was based on results from the pivotal Phase III head-to-head clinical trial (SOPHIA) evaluating the safety and efficacy of Margenza vs. Herceptin (trastuzumab), both combined with chemotherapy.
Pursuant to the terms of the agreement, TerSera will pay MacroGenics $40 million at closing. MacroGenics may receive additional sales milestone payments of up to an aggregate of $35 million. The transaction is expected to close in the fourth quarter of 2024, subject to customary closing conditions.
