C-CAR168, an Autologous Anti-CD20/BCMA Chimeric Antigen Receptor T-Cell Therapy, in Participants With Lupus Nephritis Refractory to Standard Therapy

This is a global, multicenter, single-arm, open-label Phase 2 study evaluating C-CAR168, an autologous dual-targeted anti-CD20/BCMA CAR T-cell therapy, in participants with biopsy-confirmed refractory lupus nephritis who are not responding to standard therapy. Participants will undergo screening, leukapheresis, manufacture of autologous C-CAR168, lymphodepleting chemotherapy consisting of fludarabine and cyclophosphamide, followed by a single intravenous infusion of C-CAR168. The study begins with a safety run-in involving the first five participants. Following review by the Safety Monitoring Committee (SMC), enrollment of the remaining participants may proceed if predefined safety criteria are met. Participants will be followed for 104 weeks after infusion for evaluation of efficacy, safety, pharmacokinetics, pharmacodynamics, immunologic biomarkers, and patient-reported outcomes. Participants will subsequently be invited to enroll in a separate long-term follow-up study for continued safety monitoring consistent with FDA recommendations for gene-modified cellular therapies.
