简要总结
A Phase 1 Study Evaluating BAFFR-targeting CAR T Cells for Patients with Relapsed or Refractory B-cell Acute Lymphoblastic Leukemia
详细描述
This phase I trial evaluates the side effects and best dose of BAFFR-CAR T cells in treating patients with B-cell Acute Lymphoblastic Leukemia that has come back (recurrent) or does not respond to treatment (refractory). T cells are infection fighting blood cells that can kill cancer cells. The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize BAFFR, a protein on the surface of cancer cells. These BAFFR-specific T cells may help the body's immune system identify and kill BAFFR+ cancer cells.

结局指标
主要结局
Incidence of adverse events
时间窗: Up to 1 year post treatment
Toxicity will be graded per Common Terminology Criteria for Adverse Events version 5.0, Cytokine Release Syndrome (CRS) and neurotoxicity which use the American Society for Transplantation and Cellular Therapy Consensus Criteria (ASTCT) and Graft versus Host Disease (GVHD) criteria. Toxicities will be followed from the start of lymphodepletion until the end of the study.
次要结局
- Minimal residual disease (MRD)(Up to 1 year post treatment)
- B cell frequency(Up to 1 year post treatment)
- Disease response(Up to 1 year post treatment)
- Progression-free survival (PFS)(From T cell infusion to the first observation of disease relapse/progression or death from any cause, whichever occurs first, assessed up to 15 years.)
- Overall survival (OS)(From the day of BAFFR-CAR T cell infusion to death from any cause assessed, up to 15 years.)
- Severity of graft-versus-host disease (GVHD) in recipients of prior allogeneic hematopoietic stem cell transplantation(Up to 1 year post treatment.)
