Summary

This is a prospective multi-center study to investigate efficacy and safety of the third generation tyrosine kinase inhibitors (TKIs) combined with azacitidine and B-cell lymphoma-2 (Bcl-2) inhibitor in patients with myeloid blast phase chronic myeloid leukemia (CML-MBP).

Detailed description

CML-MBP has dismal outcome. Currently, there is no standardized induction treatment approach in CML-MBP. The European LeukemiaNet (ELN) recommendations and NCCN guideline recommended the combination of TKI and chemotherapy in CML-MBP. The previous study revealed that TKI combined with hypomethylating agents had promising efficacy. However, imatinib and second generation TKI are the most widely applied in combination treatment, there is limited data in third generation TKI. Currently, venetoclax in combination with hypomethylating agents such as azacitidine is standard treatment for patients with AML unsuitable for intensive induction chemotherapy. Maiti et al. reported that TKI combined with venetoclax and detectable had promising efficacy in CML-MBP. Therefore, the investigator conducted a study to explore the efficacy and safety of a third generation TKI in combination with azacitidine and Bcl-2 inhibitor in CML-MBP and multi-omics exploratory analysis was performed to identify potential biomarkers correlated with the outcome.

Conditions
