What is DSG3-CAART?

DSG3-CAART is an autologous T-cell therapy engineered to express a chimeric autoantibody receptor containing desmoglein-3 fused to 4-1BB and CD3zeta signaling domains. It targets and kills B-cells producing DSG3 autoantibodies, reducing autoantibody production in mucosal-dominant pemphigus vulgaris.
