Condition: B ALL · Allogenetic Hematopoietic Stem Cell Transplantation · MRD-positive · Sponsor: Peking University People's Hospital
This prospective, open-label randomized controlled trial compares CD19 CAR-T therapy with chemotherapy plus donor lymphocyte infusion (DLI) in 70 patients with Ph-negative B-cell acute lymphoblastic leukemia (B-ALL) who exhibited minimal residual disease (MRD) positivity (≥0.1% CD19+ abnormal B cells) after allogeneic hematopoietic stem cell transplantation (HSCT). Patients (aged 3-\<80 years, ECOG 0-2, no relapse, adequate organ function) were randomized to receive either autologous CD19 CAR-T cells following lymphodepletion or conventional chemotherapy with DLI. The primary endpoint is the MRD negativity rate at 3 months. Secondary endpoints include 1-year MRD positivity, relapse rate, overall survival, disease-free survival, GVHD incidence, GVHD-free relapse-free survival, and duration of severe hematological toxicity. The study includes a 1-year follow-up and permits crossover to the alternative treatment for patients with persistent MRD (≥0.1%) at 3 months in the absence of relapse.
