Summary

A single arm, open-label pilot study is designed to determine the safety and effectiveness of anti-cluster of differentiation antigen 19 (CD19) chimeric antigen receptor (CAR) natural killer (NK) cells (KN5501) in patients with moderate to severe refractory systemic lupus erythematosus (SLE). 36 patients are planned to be enrolled in the dose-escalation trial. The primary objective of the study was to evaluate the safety of allogeneic anti-CD19 CAR-NK cells (KN5501) for the treatment of patients with moderate to severe refractory active SLE. The secondary objective is to evaluate the efficacy of anti-CD19 CAR NK cells (KN5501) in patients with moderate to severe refractory SLE, including British Isles Lupus Assessment Group 2004 (BILAG-2004) index, Systemic Lupus Erythematosus Responder Index (SRI)-4 response rate, Lupus Low Disease Activity State (LLDAS) rate, and Definitions Of Remission In SLE (DORIS) remission rate.
