A Phase 2 Study of Bcl-2 Inhibitor Combined With Azacitidine for Newly Diagnosed Mixed Phenotype Acute Leukemia
China52 participantsStarted 2026-05-01
Plain-language summary
This is a prospective, open-label, single-arm, two-cohort Phase 2 clinical study designed to evaluate the efficacy and safety of Bcl-2 Inhibitor combined with azacitidine (with blinatumomab added in B/myeloid subtype) in patients with newly diagnosed mixed phenotype acute leukemia (MPAL). Eligible subjects are divided into two cohorts based on immunophenotype: Cohort A (T/Myeloid MPAL) receives Bcl-2 Inhibitor + azacitidine, and Cohort B (B/Myeloid MPAL) receives Bcl-2 Inhibitor + azacitidine + blinatumomab. The treatment cycle is 28 days, with the primary efficacy endpoint assessed after 2 cycles of induction therapy. Patients who achieve CRc will undergo allogeneic hematopoietic stem cell transplantation (allo-HSCT) following 2 to 3 cycles of consolidation therapy.The total enrollment period is 24 months, and all subjects will be followed up for at least 24 months from the first day of the first cycle (C1D1).
The primary objective is to evaluate the composite complete response (CRc) rate after 2 cycles of induction therapy , and the secondary objectives include evaluating measurable residual disease (MRD) negativity rate, bridge-to-allogeneic hematopoietic stem cell transplantation (allo-HSCT) rate in first complete response (CR1), overall survival(OS),Event-Free Survival(EFS),Relapse-Free Survival(RFS) and Safety.
