NCT07257419
CD45RA-depleted CD19-CAR T Cell Consolidation After TCRαβ+/CD19 B Cell-depleted Haploidentical Hematopoietic Cell Transplantation for Relapsed/Refractory CD19+ ALL and Lymphoma
The purpose of this study is to learn more about newer methods of transplanting blood cells donated by a partially matched family member to children with high-risk CD19 positive leukemia ALL. Primary Objective: \- To assess the safety and feasibility of combining CD19-CAR(Mem) T cells after TCRαβ+/CD19 depleted haploidentical donor transplantation for pediatric patients with relapsed/refractory CD19+ B-cell malignancies. Secondary Objectives: * To estimate 1-year post-transplant overall survival, event-free survival, and GVHD-free relapse-free survival (GRFS). * To estimate cumulative incidence of engraftment, acute and chronic GVHD, and immune-related adverse events, including CRS and ICANS.

Anti-CD19, Dual Co-stimulatory (4-1BB, CD3ζ) Chimeric Antigen Receptor T-cells in Patients With Relapsed/Refractory Aggressive Lymphoma or Acute Lymphoblastic Leukemia (ALL)
Autologous, unselected CD3+ lymphocytes collected from apheresis, transfected with a lentiviral vector containing a 2nd generation chimeric antigen receptor (CAR) consisting of a scFv recognizing CD19 and dual co-stimulatory intracellular signaling domains (4-1BB and CD3ζ).

Bridging Allogeneic Hematopoietic Stem Cell Transplantation or Not After CD19 CAR - T (S1904) Cell Therapy for r/r B-cell Acute Lymphoblastic Leukemia
Traditional salvage chemotherapy has low efficacy and poor long-term prognosis for relapsed or refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL). Targeted CD19 CAR-T cell immunotherapy is an effective means of treating R/R B-ALL. Several clinical studies have shown that its remission rate for R/R B-ALL can reach 68-93%. However, long-term follow-up found that the remission time after CD19 CAR-T treatment is short and the relapse rate is high. Therefore, how to ensure the long-term survival of R/R B-ALL patients after remission by CAR-T therapy is an urgent problem to be solved. Some studies have shown that timely bridging allo-HSCT after CAR-T treatment can overcome the risk of relapse and further improve the long-term survival of patients. However, there is currently no randomized controlled study on whether to bridge transplantation after CAR-T. The purpose of this study is to evaluate the efficacy and safety of S1904 in the treatment of relapsed or refractory CD19-positive B-cell acute lymphoblastic leukemia with or without bridging to allogeneic hematopoietic stem cell transplantation after remission.
