简要总结
This phase I/II trial studies the safety and toxicity of post-transplant treatment with donor T cells engineered to express a chimeric antigen receptor (CAR) targeting CD19 in patients who have had a matched related allogeneic hematopoietic stem cell transplant for a CD19+ B cell malignancy.
详细描述
PRIMARY OBJECTIVES:
I. To assess the safety and feasibility of pre-emptive adoptive T cell therapy using ex vivo expanded cytomegalovirus (CMV)- or Epstein-Barr virus (EBV)-specific T cells derived from donor CD62L+ central memory (TCM) cells and genetically modified to express a CD19-specific chimeric antigen receptor (CAR) in patients in complete remission after human leukocyte antigen (HLA)-matched related donor hematopoietic stem cell transplantation (HCT) for CD19+ B cell malignancies at high risk of post-HCT relapse. (Cohort A)
II. To assess the safety and feasibility of adoptive T cell therapy using ex vivo expanded CMV- or EBV-specific T cells derived from donor CD62L+ TCM cells and genetically modified to express a CD19-specific CAR in patients with persistent, progressive or relapsed disease after HLA-matched related donor HCT for CD19+ B cell malignancies. (Cohort B)
SECONDARY OBJECTIVES:
I. To determine the duration of in vivo persistence of adoptively transferred bi-specific CD8+ T cells, and the phenotype of persisting T cells.

结局指标
主要结局
Feasibility assessment of study treatment
时间窗: Up to 5 years
If the prescribed T cell dose is delivered in more than 50% of the patients, this approach will be considered feasible for further study to reduce relapse after allogeneic HCT.
Safety and toxicity assessment of study treatment
时间窗: Up to day 42 after the T cell infusion
Incidence of grade \>= 3 toxicity, as defined by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 occurring from the T cell infusion through day 42 after the T cell infusion. Analysis will be performed separately in patients in complete remission (cohort A) or with detectable disease (cohort B) at day 28 post-transplant (prior to the T cell infusion). Incidence of acute GVHD occurring from the T cell infusion through day 42 after the T cell infusion will be assessed.
次要结局
- Anti-tumor efficacy and duration of persistence, migration, and function of adoptively transferred bi-specific effector cells(Up to 15 years)
