Dose Optimization Trial of CD19 Redirected Autologous T Cells

Phase 2
Completed
Conditions
Adult Patients Who Have Relapsed or Refractory CLL (3rd Line) or SLL
Interventions
Biological: CART-19
Registration Number
NCT01747486
Lead Sponsor
University of Pennsylvania
Brief Summary

This is a randomized, open-label, parallel group study to determine the optimal dose of CART-19 cells (autologous T cells expressing CD19 chimeric antigen receptors expressing tandem TCR Zeta and 4-1 BB co-stimulatory domains) of the two dose levels being assessed (1-5x10e8 vs. 1-5x10e7 CART-19 cells). This trial will be conducted in two stages.

Detailed Description

This study is being conducted to determine the optimal dose of autologous CART-19 T cells engineered to express anti-CD19 chimeric antigen receptors in patients with relapsed or refractory CD19 positive chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). The two dose levels being assessed are 1-5x10e8 versus 1-5x10e7. The trial will be conducted in two stages. In stage I subjects will be randomized into one of the two dose cohort with a1:1 ratio for a total of 12 subjects per dose cohort. Stage II will be to enroll an additional 8 subjects to the selected dose cohort once safety, tolerability and clinical responses have been evaluated to determine the optimal dose cohort.

Number of Patients Achieving Complete Response Within 3 Months3 months

Complete response (including complete response with incomplete marrow recovery) within 3 months (in evaluable patients). The eveluable set comprise of patients who have received CART19 at intended dose level and completed at least 3-month follow-up after the infusion or discontinued due to disease progression, new cancer therapy or death.
