简要总结

The trial is a single arm, single-center, non-randomized phase I clinical trial which is designed to evaluate the safety and efficacy of C-CAR011 in treatment of refractory DLBCL

详细描述

The 3x3 dose escalation design will be adopted in order to determine the maximum tolerated dose (MTD). Subjects will be enrolled into low-dose group, medium-dose group and high-dose group as below:

Dose CAR+ cells/kg

Low 0.8×106

Medium 2.5×106

High 5.0×106

研究组 & 干预措施

C-CAR011

Experimental

C-CAR011 infusion In the first cell therapy 0, 1 and 2 days, respectively 10%, 30% and 60% ratio three times reinfusion.

干预措施: C-CAR-011 (Biological)

结局指标

主要结局

Dose-limiting toxicity (DLT)

时间窗: 28 days

Non-haematological dose-limiting toxicities was any toxicity of grade 3 or higher occurring within 28 days of C-CAR011 infusion judged possibly related to the treatment regimen.The following toxicities were not considered dose limiting toxicities: tumor lysis syndrome, abnormal electrolytes responding to supplementation, hypoalbuminemia, liver dysfunction resolving to ≤grade 2 within 14 days, transient (\<72 hours) grade 4 hepatic enzyme abnormality, and grade 3 or 4 fever or neutropenic fever.

次要结局

  • Overall response rate(4 and 12 weeks)
  • Disease control rate(12 weeks)
