Our RESETTM clinical trials with CABA-201 (investigational CD19-CAR T cell therapy) in lupus, myositis, systemic sclerosis, and myasthenia gravis are now recruiting.


Clinical-stage targeted cell therapy pipeline for autoimmune diseases

In certain autoimmune diseases, pathogenic B cells secrete autoantibodies, or antibodies that mistakenly target healthy host proteins, which are responsible for causing disease.

Advancing Innovative T Cell Therapy Candidates in Autoimmune Disease

We are targeting a portfolio of autoimmune diseases with our engineered T cell therapy candidates. Our lead Chimeric Antigen Receptor T cell for Autoimmunity (CARTA) candidate, CABA-201, is being advanced in the RESETTM (REstoring SElf-Tolerance) Phase 1/2 clinical trials in systemic lupus erythematosus, myositis, systemic sclerosis and generalized myasthenia gravis, with potential application in a broad portfolio of other autoimmune diseases in rheumatology, neurology, and other therapeutic areas.

Chimeric Antigen Receptor T cells for Autoimmunity: CABA-201

We are developing CABA-201, a fully human CD19 chimeric antigen receptor (CAR) T cell therapy containing a 4-1BB co-stimulatory domain, for autoimmune diseases with high unmet need. The fully human CD19 binder has been clinically evaluated in a dual-CD19xCD22 CAR T in cancer through an investigator-initiated trial, where it has shown promising tolerability in ~20 patients. CABA-201 is designed to be given as a one-time infusion, with the potential to transiently, but fully, eliminate B cells, thus enabling a potential “immune system reset” and durable responses for patients with autoimmune disease. We are advancing CABA-201 in the RESETTM Phase 1/2 clinical trials in systemic lupus erythematosus, myositis, systemic sclerosis and generalized myasthenia gravis.
