On December 11, 2023, Sanofi released a statement that it will terminate its proposed $755 million licensing agreement with Maze Therapeutics (Maze) shortly after the Federal Trade Commission (FTC) issued an administrative complaint and authorized filing a complaint for preliminary injunction in the United States District Court for the District of Massachusetts to block the deal.
Under the terms of the proposed licensing agreement between Genzyme Corporation, a wholly-owned subsidiary of Sanofi, and Maze, Sanofi would acquire an exclusive license to Maze’s glycogen synthase 1 products and related technology, including its candidate MZE001, a drug in development to treat the potentially fatal genetic order Pompe disease. According to a statement by Jason Coloma, Ph.D., Maze’s CEO, the FTC’s challenge “is the first time ever the FTC has moved to block a license of a Phase 1 investigational medicine.” The challenge seems consistent, however, with revised draft merger guidelines proposed by the FTC and Department of Justice that indicate that transactions “should not entrench or extend a dominant position” by, for example, “[e]liminating a nascent competitive threat.”
