An Open-Label, Single-Arm, Phase II Exploratory Study of ABL and JAK Kinase Inhibitors With Chemotherapy and Venetoclax in Adult Patients With Ph-like ALL
An Open-Label, Single-Arm, Phase II Exploratory Study of ABL and JAK Kinase Inhibitors With Chemotherapy and Venetoclax in Adult Patients With Ph-like ALL
This open-label, non-randomized, phase II exploratory study aims to evaluate the efficacy and safety of combining pathway-specific tyrosine kinase inhibitors with chemotherapy and venetoclax in patients with newly diagnosed Ph-like acute lymphoblastic leukemia (ALL). Patients are stratified by genetic alteration: those with ABL class fusions (ABL1, ABL2, PDGFRA, PDGFRB) receive olverembatinib, while those with JAK pathway alterations (CRLF2 rearrangement, JAK mutation/fusion, EPOR fusion, SH2B3 deletion, IL7R mutation) receive Gecacitinib. Both groups undergo sequential induction, consolidation, intensification, and maintenance therapy as per protocol.
The primary endpoint is the rate of flow cytometry minimal residual disease (MRD)-negative complete remission (CR MRD-) at 3 months after induction therapy. Secondary endpoints include overall complete remission rate, NGS MRD-negative CR rate at 3 months, overall survival (OS), disease-free survival (DFS), relapse-free survival (RFS), cumulative incidence of relapse, and 60-day mortality.
