Company description

We are a late clinical-stage biotechnology company focused on the discovery and development of innovative engineered T cell therapies that have the potential to provide deep and durable, perhaps curative, responses with one-time administration for patients with autoimmune diseases. Our proprietary CABA ®, or Cabaletta Approach to B cell Ablation platform, focuses on the CARTA approach. CARTA refers to Chimeric Antigen Receptor T cells for Autoimmunity and is designed to potentially reset the immune system. Based on clinical data reported to date, we believe our CABA ® platform has the potential to safely enable complete and durable responses for a broad range of autoimmune diseases and that it has potential applicability across dozens of autoimmune diseases that we have identified, evaluated and prioritized. Resecabtagene autoleucel, or rese-cel (formerly referred to as CABA-201), is a 4-1BB co-stimulatory domain-containing fully human CD19-CAR T construct designed to treat patients with a broad range of autoimmune diseases and our lead product candidate within the CARTA strategy. Rese-cel is designed to achieve transient and deep depletion of all B cells following a single, weight-based infusion of T cells that are engineered to express an antibody fragment that recognizes a B cell receptor expressed on the surface of all B cells. The construct is designed to allow for the deep elimination of all B cells, including all B cells that contribute to disease, with subsequent repopulation by healthy transitional, naïve B cells.
