Chronic Myeloid Leukaemia Transformation, Chronic Myeloid Leukemia - Accelerated Phase, Chronic Myeloid Leukemia in Lymphoid Blast Crisis, Chronic Myeloid Leukemia in Myeloid Blast Crisis
Conditions
Brief summary
This phase II trial studies how well the combination of based decitabine and olverembatinib（HQP1351)chemotherapy work for the treatment of blast phase or accelerated phase chronic myelogenous leukemia. Drugs used in chemotherapy such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. HQP1351 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving decitabine and ponatinib based chemotherapy may help to control blast phase or accelerated phase chronic myelogenous leukemia.
Detailed description
Accelerated Phase CML treated with decitabine10mg/m2 d1-5 intravenously (IV) over 60 minutes on days 1-5 and olverembatinib（HQP1351) 40mg qod every 28 days.After completion of HQP1351 lead-in, patients will receive HQP1351 PO daily on days 1-28 of subsequent cycles. chronic myeloid leukaemia in blast phase:treated with decitabine 20mg/m2 d1-5 intravenously (IV) over 60 minutes on days 1-5 and HQP1351 40mg qod every 28 days,with or without other chemotherapy drugs

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall response rate | At 12 weeks | Defined as the proportion of patients achieving complete remission (CR) + CR with incomplete count recovery (CRi) occurring at the end of 2 cycles of treatment. Will be estimated along with the 95% credible interval. Patients who drop out of the study before completing 2 cycles and have been treated will be censored for the primary endpoint analysis. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Relapse-free survival | 3 years | From documented complete response until relapse or death |
| Event-free survival | 3 years | From first day of treatment until any failure (resistant disease, relapse, or death) |
| Overall survival | assessed up to 3 years | First day of treatment to time of death from any cause |
