GoFast CAR T-Cell Therapy for Recurrent Refractory B-Cell Lymphoma

25 giugno 2026 aggiornato da: Chunji Gao, Chinese PLA General Hospital

Exploratory Clinical Study of GoFast CAR T-Cell Platform Targeting CD19 CAR T-Cell Therapy for Recurrent Refractory B-Cell Lymphoma

This is an investigator-initiated, prospective, open-label exploratory clinical study designed to evaluate the safety and preliminary efficacy of GoFast CD19 CAR T-cell therapy in adult patients with recurrent or refractory B-cell lymphoma. Eligible patients will undergo screening, baseline assessment, peripheral blood or leukapheresis collection, lymphodepleting chemotherapy, and intravenous infusion of GoFast CD19 CAR T cells. The study plans to enroll 9 participants using a sequential dose-escalation design. The primary outcome is objective response rate, and secondary outcomes include complete remission rate, overall survival, progression-related survival outcomes, duration of response, MRD negativity, and adverse events.

Descrizione dettagliata

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.
