Summary

This is a prospective, open-label, randomized controlled trial to evaluate the efficacy of low-intensity chemotherapy combined with venetoclax and blinatumomab in newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL). Patients will be randomized to receive or not receive venetoclax during the first three cycles of induction and consolidation therapy. All patients receive olverembatinib (a third-generation TKI) continuously and may receive up to 4 cycles of blinatumomab starting from the fourth cycle. The primary endpoint is the rate of BCR::ABL1 ≤0.01% at 90 days and event-free survival (EFS). Secondary endpoints include overall survival (OS), relapse-free survival (RFS), molecular relapse rate, MRD negativity rate by NGS, and cardiovascular events.

Conditions

  • Ph+ ALL

Interventions

DRUG

Olverembatinib

Third-generation tyrosine kinase inhibitor (TKI) targeting BCR-ABL1, including T315I mutation.nduction \& Consolidation: 40mg every other day. After achieving CMR: Reduced to 20mg every other day during maintenance.

DRUG

Venetoclax

BCL-2 inhibitor. Used only in the experimental arm.Induction: Ramp-up: 100mg D1, 200mg D2, 400mg D3-28. Consolidation: 400mg D1-7.

DRUG

Blinatumomab

CD19/CD3 bispecific T-cell engager (BiTE). Optional add-on therapy.Start: After first consolidation. Duration: 1-4 cycles (each cycle = 28 days), intercalated with chemotherapy cycles. Note: If ≥3 cycles given,cycle 8 and 9 are omitted.

DRUG

Chemotherapy Backbone Regimens

Induction (VPO/VPVO): Vincristine + Prednisone + Olverembatinib (± Venetoclax). Consolidation (VOVP/OVP): Vincristine +Olverembatinib + Prednisone (± Venetoclax). HD-MTX: High-dose methotrexate with leucovorin rescue in cycle 4,6,8. ID-AraC: Intermediate-dose cytarabine in cycle 5,7,9.

OTHER

Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT)

Recommended for patients with MRD ≥0.01% after two treatment blocks.
