Profile
A Philadelphia clinical-stage biotech focusing its CARTA platform on rese-cel, an investigational CD19-CAR T therapy in the multi-indication RESET program.
Built around engineered T-cell approaches to autoimmune disease, the CABA platform has two strategies: CARTA and CAART. CARTA is being prioritized around rese-cel, formerly CABA-201, a fully human CD19-CAR T investigational therapy evaluated in the multi-indication RESET program. That program spans a range of autoimmune disease settings in rheumatology, neurology, and dermatology.
Headquarters and laboratories are in Philadelphia. The scientific origin traces to a University of Pennsylvania collaboration combining autoimmune-disease research with CAR-T design. Development depends on clinical progress, regulatory alignment, manufacturing, and external capital because the therapies remain investigational.
