A Study of IMPT-514 in Active Refractory Lupus Nephritis (LN) and Systemic Lupus Erythematosus (SLE)

This is a Phase 1/2, multi-center, open-label study evaluating the safety and efficacy of IMPT-514, a bispecific chimeric antigen receptor (CAR) targeting cluster of differentiation (CD)19 and CD20 in participants with active, refractory lupus nephritis and systemic lupus erythematosus. IMPT-514 treatment consists of a single infusion of CAR-transduced autologous T cells administered intravenously after a lymphodepleting therapy regimen consisting of fludarabine and cyclophosphamide. Individual participants will remain in the active post-treatment period for approximately 1 year. Participants will continue in long-term follow-up for 15 years from treatment.
