We are a clinical-stage biotechnology company focused on the discovery and development of engineered T cell therapies for B cell-mediated autoimmune diseases. Our proprietary technology utilizes chimeric autoantibody receptor, or CAAR, T cells that are designed to selectively bind and eliminate B cells that produce disease-causing autoantibodies, or pathogenic B cells, while sparing normal B cells. Our lead CAAR T cell product candidate was designed based on chimeric antigen receptor, or CAR, T cell technology that has been successfully developed and is marketed for the treatment of B cell cancers.
