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, including SLE/lupus nephritis and myositis and which uses a CD-19 binder that has an encouraging clinical tolerability profile. The second strategy is Cabaletta Bio’s proprietary CAART, or chimeric autoantibody receptor T cells, strategy, which is designed to cause antigen-specific B cell depletion of well-defined, disease-causing B cells. Our lead product candidate developed using the CAART strategy is being evaluated in a clinical trial for patients with mucosal pemphigus vulgaris (mPV) and our second product candidate is expected to initiate a clinical trial later this year in muscle-specific tyrosine kinase (MuSK) myasthenia gravis. Cabaletta Bio’s headquarters are located in Philadelphia, PA. For more information, visit and follow us on LinkedIn and Twitter.
