简要总结
This phase Ib trial is to find the side effect and best dose of navitoclax when given together with venetoclax and decitabine in treating patients with acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory) after previous treatment with venetoclax. Chemotherapy drugs, such as navitoclax, venetoclax, and 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.
详细描述
PRIMARY OBJECTIVES:
I. Assess safety and determine the optimal biological doses (OBD). II. Evaluate the anti-leukemic activity, as assessed by overall response rate (ORR: complete response [CR] + complete response with incomplete hematopoiesis [CRi] + partial response [PR]) within the first 35 days (cycle 1).
SECONDARY OBJECTIVES:
I. Characterize safety and tolerability of navitoclax/venetoclax during the first 7 days of cycle 1.
II. Obtain preliminary estimates of:
