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

Small Cell Lung Cancer Extensive Stage Clinical Trial

Official title:
Phase I Clinical Study on Safety and Feasibility of DLL3 Targeted α-PD-L1/4-1BB Modifying Chimeric Antigen Receptor T-cells in Patients With Relapsed or Refractory Small Cell Lung Cancer (SCLC)

Clinical Trial 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.

Clinical Trial Description

Small cell lung cancer (SCLC) accounts for about 15% of lung cancers, and two-thirds of cases are metastatic at the time of diagnosis. The inhibitory notch ligand delta-like ligand 3 (DLL3) is aberrantly expressed on the surface of up to 85% of SCLC cells and minimally expressed in normal tissues, making it a compelling therapeutic target. This is a phase I, first-in-human, 3+3 dose escalation study to evaluate the safety and feasibility of BHP01 in patents with relapsed/refractory SCLC who progressed after at least 1 platinum based chemotherapy regimen.This is a dose escalation and dose expansion study. 12-21 patients with relapsed/refractory SCLC are planned to be enrolled (Group Pre-A/A/B/C). After the Dose-limiting toxicity (DLT) observation period of the related dose group finished.16 patients are planned to enroll in dose expansion phase who was assign two groups with/without bridge radiotherapy. ;
