Summary

A single arm, open-label pilot study is designed to determine the safety and effectiveness of anti-CD19 CAR NK cells (KN5501) in patients with relapsed/refractory B-cell related autoimmune diseases.15 patients are planned to be enrolled in the dose-escalation trial (6×10\^9 cells, 9×10\^9 cells). The primary objective of the study is to evaluation of the safety and feasibility of KN5501 for the treatment of relapsed/refractory B-cell related autoimmune diseases. The secondary objective is to evaluate the effectiveness of KN5501 for the treatment of relapsed/refractory B-cell related autoimmune diseases. The exploratory objective is to evaluate expansion, persistence and ability to deplete CD19 positive B cells of KN5501 in patients with relapsed/refractory B-cell related autoimmune diseases.
