简要总结
A single arm, open-label, dose-escalation study to evaluate the safety and clinical activity of ThisCART22 (Allogeneic CAR-T targeting CD22) in patients with relapsed and/or refractory non-Hodgkin's B cell lymphoma (r/r B-NHL).
详细描述
ThisCART22 cell is a non-gene-editing allogeneic CAR-T cell targeting CD22. This study is designed to evaluate the safety and clinical activity of ThisCART22 in patients with CD22 positive, relapsed and/or refractory non-Hodgkin's B cell lymphoma (r/r B-NHL).
