Merck, known as MSD outside the U.S. and Canada, will acquire Rigontec. Rigontec is a pioneer in accessing the retinoic acid-inducible gene I (RIG-I) pathway, part of the innate immune system, as a novel and distinct approach in cancer immunotherapy to induce both immediate and long-term anti-tumor immunity. Rigontec’s lead candidate, RGT100, is currently in phase I development evaluating treatment in patients with various tumors. Under the terms of the agreement, Merck, through a subsidiary, will make an upfront cash payment of €115 million to Rigontec’s shareholders; based on the attainment of certain clinical, development, regulatory and commercial milestones, Merck may make additional contingent payments of up to €349 million. The transaction is subject to certain closing conditions.
