Detailní popis
This study will enroll adult patients with recurrent or refractory B-cell lymphoma who are CD19-positive and meet the protocol-defined eligibility criteria. After signing informed consent, participants will undergo screening assessments, including medical history, physical examination, performance status assessment, laboratory tests, infection screening, imaging evaluation, and assessment of feasibility for CAR T-cell preparation.
Eligible participants will undergo peripheral blood or leukapheresis collection for preparation of autologous GoFast CD19 CAR T cells. Before CAR T-cell infusion, participants will receive lymphodepleting chemotherapy with fludarabine 30 mg/m2 and cyclophosphamide 300 mg/m2 from Day -5 to Day -3. After completion of lymphodepletion, GoFast CD19 CAR T cells will be administered by intravenous infusion according to the assigned dose cohort.
The study uses a dose-escalation design with three planned dose cohorts: 0.3 × 10^6 cells/kg, 0.6 × 10^6 cells/kg, and 1.2 × 10^6 cells/kg. Each participant will receive a fixed dose according to the assigned cohort. Dose escalation will proceed only after review of safety data from the previous cohort and confirmation that no dose-limiting toxicity or other unacceptable safety signal has occurred.
Participants will be closely monitored after CAR T-cell infusion for adverse events, including cytokine release syndrome, neurotoxicity, tumor lysis syndrome, cytopenia, infection, organ dysfunction, and laboratory abnormalities. CAR T-cell expansion, lymphocyte subsets, cytokines, blood routine tests, biochemical tests, coagulation function, and organ function will be evaluated at protocol-defined time points.
Tumor response will be assessed using imaging and clinical evaluation at predefined follow-up visits, including Day 28 and Week 12 after CAR T-cell infusion. Participants with complete or partial response will continue follow-up for up to 1 year after enrollment. The primary endpoint is objective response rate. Secondary endpoints include complete remission rate, overall survival, time to progression, disease-free survival, duration of response, event-free survival, MRD negativity rate, and the incidence and severity of adverse events.
