Cabaletta Bio is a clinical-stage biotechnology company focused on the discovery and development of engineered T cell therapies for patients with B cell-mediated autoimmune diseases. The Cabaletta Approach to selective B cell Ablation (CABA) platform, in combination with Cabaletta’s proprietary technology, utilizes Chimeric AutoAntibody Receptor (CAAR) T cells that are designed to selectively bind and eliminate only specific autoantibody-producing B cells while sparing normal antibody-producing B cells, which are essential for human health. Cabaletta’s lead product candidate is based on the Chimeric Antigen Receptor (CAR) T cell technology developed at the University of Pennsylvania (Penn) that resulted in one of the first commercially-available CAR T cell products for the treatment of B cell cancers. Cabaletta was founded by Penn physician/scientists Michael Milone, M.D., Ph.D., and Aimee Payne, M.D., Ph.D., who serve as co-chairs of Cabaletta’s Scientific Advisory Board, and Steven Nichtberger, M.D., CEO of Cabaletta. Cabaletta has an exclusive global licensing agreement and multiple sponsored research agreements with the University of Pennsylvania to develop the CAAR T technology to treat B cell-mediated autoimmune diseases. The Company’s lead product candidate is being studied as a potential treatment for a prototypical B cell-mediated autoimmune disease, mucosal pemphigus vulgaris (mPV).
