Phase I Clinical Study of α-PD-L1/DLL3 CAR-T in Patients With R/R SCLC

Summary

A study to evaluate the safety and feasibility of α-PD-L1/4-1BB DLL3 Chimeric Antigen Receptor (CAR)-T (BHP01) in patients with Relapsed/Refractory Small Cell Lung Cancer (SCLC) and determine the appropriate CAR-T cell dose. Next, In dose expansion phase, patients were assign two groups with/without bridge radiotherapy.
