Brief summary
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) improves the long-term outcomes for Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) and BC-CML. Relapse remains a major cause of treatment failure even after allo-HSCT. The prevention of relapse is essential for improving the outcome of Ph+ ALL. Pre-emptive tyrosine kinase inhibitor (TKIs) administration based on minimal residual disease (MRD) and BCR-ABL mutation after allo-HSCT might reduce the incidence of relapses and improve survival for patients with Ph+ luekemia. In this study, we will evaluate the safety and efficacy of newly third TKI-HQP1351 therapy post-transplants on Ph+ leukemia after allo-HSCT with MRD positive pre-transplants.
Interventions
HQP1351 was initiated at a dose of 40mg every two days
