Brief Summary

The purpose of this clinical trial is to evaluate the safety and efficacy of CAR1922T2 T-cell therapy in participants with relapsed/refractory B-cell acute lymphoblastic leukemia and non-Hodgkin's lym...

Detailed Description

Acute lymphoblastic leukemia (ALL) is a hematological malignancy characterized by the clonal proliferation of precursor lymphoid cells, with a cure rate of only 30-40% in adults through standardized c...
