A Phase 1 Study Evaluating Safety and Efficacy of C-CAR011 Treatment in DLBCL Subjects (C-CAR011)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT02976857
Recruitment Status : Completed
First Posted : November 29, 2016

Cellular Biomedicine Group Ltd.

Brief Summary:
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

Condition or disease Intervention/treatment Phase
Refractory Diffuse Large B-Cell Lymphoma Biological: C-CAR-011 Phase 1

Detailed Description:

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

DLT is evaluated within 30 days post C-CAR011 infusion).

Arm Intervention/treatment
Experimental: C-CAR011
C-CAR011 infusion In the first cell therapy 0, 1 and 2 days, respectively 10%, 30% and 60% ratio three times reinfusion.
Biological: C-CAR-011
lymphocytes will be transduced with lentiviral vector containing CAR-CD19 gene.
Other Name: CAR-CD19

Primary Outcome Measures :
  1. Dose-limiting toxicity (DLT) [ Time Frame: 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.

Secondary Outcome Measures :
  1. Overall response rate [ Time Frame: 4 and 12 weeks ]
    Overall response rate (ORR) = complete response (CR) rate + partial response (PR) rate, ORR will be assessed at weeks 4 and weeks 12 according to International Working Group (IWG) revised criteria.

  2. Disease control rate [ Time Frame: 12 weeks ]
    Disease control rate (DCR) = complete response (CR) rate + partial response (PR) rate + stable disease (SD) rate, DCR will be assessed at weeks 12 according to International Working Group (IWG) revised criteria.
