Relapsed and Refractory B-cell Lymphoma Clinical Trial
Official title:
Exploratory Clinical Study of CD19-targeted CAR-T and CAR-DC in the Treatment of Relapsed and Refractory B-cell Lymphoma
This is an open, single-arm, prospective, dose-escalation clinical trial designed to evaluate the safety and the preliminary efficacy of CD19-targeted CAR-T combined with CAR-DC in the treatment of relapsed and refractory B-cell lymphoma
6-18 patients are planned to be enrolled in the dose-escalation trial. The dose of CD19-CAR-DC was according to the 3+3 dose-escalation principle (0.25×10^6/kg, 0.5×10^6/kg, 0.75×10^6/kg ( ±20%) . CAR-T was 2×10^6/kg . The primary endpoints are DLT, MTD, and the second endpionts are the overall response rates (CR and PR), overall survival, and progression-free survival. Based on the results in the dose-escalation trial, the recommended dose will be determined. Another 52 patients will be enrolled to continue estimating the safety and efficacy. ;
