Philadelphia, PA

Cabaletta Bio (Nasdaq: CABA) is a clinical-stage biotechnology company focused on developing and launching targeted, potentially curative, cellular therapies for patients with autoimmune diseases. The CABA™ platform includes two strategies to treat and potentially cure many of the most common and challenging autoimmune diseases. The CARTA strategy, or Chimeric Antigen Receptor T cells for Autoimmunity, is designed to potentially reset the immune system by causing transient B cell depletion with early academic clinical data suggesting the potential of this strategy to transform treatment in patients with SLE and the possibility of cures in rheumatoid arthritis, myositis, and systemic sclerosis, among others. Our lead product candidate using the CARTA strategy is CABA-201, 4-1BB-containing CD19-CAR T designed specifically to treat patients with autoimmune diseases with high unmet need, including systemic lupus erythematosus (SLE), myositis, systemic sclerosis, and generalized myasthenia gravis, and which uses a CD-19 binder that has an encouraging clinical tolerability profile. In addition to our CARTA candidate, CABA-201, we have a clinical-stage pipeline of Chimeric AutoAntibody Receptor T (CAART) cells targeted to the cells responsible for autoantibody-mediated autoimmune diseases.  Cabaletta Bio’s headquarters are located in Philadelphia, PA.
