A Single-Arm, Open-Label, Phase I Study to Determine the Safety, Tolerability and Preliminary Efficacy of Obecabtagene Autoleucel in Patients With Severe, Refractory Systemic Lupus Erythematosus
This is a Phase 1 study of obecabtagene autoleucel (obe-cel), autologous T cells engineered with a chimeric antigen receptor (CAR) targeting CD19, to establish the tolerability, safety, preliminary efficacy, and pharmacokinetics of obe-cel in patients with severe, refractory SLE.
