CAR-T

This is a single-arm single center study to prospectively evaluate the safety and efficacy of ultra-fraction radiotherapy bridging CAR-T therapy in relapsed/refractory diffuse large b cell lymphoma

This is a single site, non-randomized, open-label, long-term safety and efficacy follow-up study for Phase 1 studies that evaluate the safety and efficacy of CAR T cells: NCT05660369 (DF/HCC# 22-175) and NCT06026319 (DF/HCC# 23-474).

A study to evaluate the safety and preliminary efficacy of CLL-1-targeted CAR-T cell therapy in children aged 3 to 18 years with relapsed or refractory acute myeloid leukemia (r/r AML).

The primary purpose of the Research Database is to have a comprehensive source of observational data that can be used to study HSC transplantation and cellular therapies. A secondary purpose of the Research Database is to have a comprehensive source of data to study marrow toxic injuries. Objectives: To learn more about what makes stem cell transplants and cellular therapies work well such as: * Determine how well recipients recover from their transplants or cellular therapy; * Determine how recovery after a transplant or cellular therapy can be improved; * Determine how a donor's or recipient's genetics impact recipient recovery after a transplant or cellular therapy; * Determine how access to transplant or cellular therapy for different groups of patients can be improved; * Determine how well donors recover from the collection procedures.

This is an open-label, single-arm, exploratory clinical trial utilizing a "3+3" dose escalation followed by dose expansion to evaluate the safety, maximum tolerated dose (MTD), pharmacokinetics (PK), and preliminary efficacy of CD33/CD123/CLL-1 CAR-T cell therapy in patients with relapsed/refractory myeloid malignancies. Part A: Dose Escalation Phase. Follows a "3+3" dose escalation design with four predefined dose cohorts: 0.2×10⁶, 0.5×10⁶, 1×10⁶, and 2×10⁶ CAR-positive cells/kg.Anticipated enrollment: 12-24 subjects.Primary objectives: Assess safety, tolerability, and determine MTD.Dose-limiting toxicity (DLT) observation period: 28 days post-infusion. Part B: Dose Expansion Phase.Enrolls 21 additional subjects to receive CAR-T cell infusion at the recommended Phase 2 dose (RP2D) established in Part A.Primary objective: Further evaluate therapeutic efficacy. Overall Study Objectives:Safety profile of CD33/CD123/CLL-1 CAR-T therapy.Efficacy endpoints (e.g., response rates, survival outcomes).Pharmacokinetic characterization of CAR-T cells (expansion/persistence).

This is a early Phase 1 open-label, single-arm clinical study of EX02 CAR-T therapy for relapsed and refractory acute myeloid leukemia. Each participant will undergo leukapheresis after enrolment, receive treatment of the conditioning chemotherapy of cyclophosphamide and fludarabine, and an an intravenous infusion of CAR-T cells. Each participant will proceed through the following study procedures: * Screening * Enrollment/Leukapheresis * Conditioning chemotherapy * CAR T treatment * Post-treatment assessment * Long-term follow-up
