Description

About Tr1X Tr1X is a private, clinical-stage biotechnology company focused on developing a novel class of regulatory T cell-based products to cure autoimmune and inflammatory diseases. Founded by industry experts, including the scientists who discovered Type 1 regulatory T (Tr1) cells, the company is developing a pipeline of off-the-shelf allogeneic cell therapies for autoimmune diseases with high unmet medical need. TRX cells are designed to mimic the function of naturally occurring Tr1 cells, which work to restore immune tolerance, stopping severe autoimmune and inflammatory disease in its tracks. Tr1X is the first company ever to use an allogeneic engineered Tr1 cell therapy in clinical trials. Tr1X is headquartered in San Diego, CA. For more information, please visit www.tr1x.bio.
