Tr1X is a privately held biotechnology company based in San Diego, California, focused on developing regulatory T cell-based therapies for autoimmune and inflammatory diseases. Its approach centers on off-the-shelf, allogeneic cell products designed to restore immune tolerance and potentially halt severe disease processes. The company’s TRX cells are intended to emulate Type 1 regulatory T cells that occur naturally in the immune system. Tr1X is noted for pursuing the first allogeneic engineered Tr1 cell therapy in clinical trials. Recent notices indicate the company plans to present clinical and preclinical data at the ASGCT 2026 meetings.
