Gilead's acquisition of Ouro Medicines will provide it with access to gamgertamig, a clinical-stage T cell engager designed for autoimmune diseases such as severe antibody-mediated orphan conditions. The deal includes an upfront payment of $1.675 billion and up to $500 million in contingent milestone payments.

The company will gain an operating business with facilities and personnel.

By integrating these programs, Gilead aims to accelerate development and commercialization efforts while enhancing its portfolio's overall therapeutic breadth.
Financial Context
Ouro Medicines had ongoing Phase 1/2 clinical studies demonstrating gamgertamig’s efficacy in treating autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP). The drug has received Fast Track and Orphan Drug Designation by the U.S. FDA.
Advisors
Morgan Stanley served as financial advisor to Gilead, while Paul Weiss Rifkind Wharton & Garrison and Linklaters provided legal counsel.
Outlook
Gilead Sciences aims to leverage Ouro Medicines' expertise in developing T cell engager therapies for autoimmune diseases. With the acquired programs now integrated into its portfolio, Gilead expects to advance clinical trials and potentially bring gamgertamig to market as early as 2027.
