研究概览
简要总结
This phase I/II trial studies the best dose of venetoclax when given together with ponatinib and dexamethasone and to see how well they work in treating participants with Philadelphia chromosome or BCR-ABL positive acute lymphoblastic leukemia or chronic myelogenous leukemia that has come back or does not respond to treatment. Drugs used in chemotherapy, such as venetoclax and dexamethasone, 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. Ponatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving venetoclax, ponatinib, and dexamethasone may work better in treating participants with acute lymphoblastic leukemia or chronic myelogenous leukemia.
详细描述
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD) of venetoclax, ponatinib, and dexamethasone in patients with relapsed/refractory Philadelphia positive (Ph+) acute lymphoblastic leukemia (ALL) or lymphoid blastic phase (BP)-chronic myelogenous leukemia (CML). (Phase I) II. To determine the efficacy of the regimen, as defined by the rate of complete remission (CR) or CR with incomplete count recovery (CRi). (Phase II)
SECONDARY OBJECTIVES:
I. To determine efficacy outcomes, including rate of minimal residual disease negativity by polymerase chain reaction (PCR) for BCR-ABL1 transcripts, median relapse-free survival (RFS), and median overall survival (OS).
II. To determine the proportion of patients proceeding to allogeneic stem cell transplant (ASCT).

Prior recent treatment with corticosteroids and hydroxyurea is permitted
- •Pregnant and lactating women will not be eligible; women of childbearing potential should have a negative pregnancy test prior to entering on the study and be willing to practice methods of contraception throughout the study period. Women do not have childbearing potential if they have had a hysterectomy or are postmenopausal without menses for 12 months. In addition, men enrolled on this study should understand the risks to any sexual partner of childbearing potential and should practice an effective method of birth control. Appropriate birth control will be determined by the treating physician

结局指标
主要结局
Maximum Tolerated Dose (MTD) of Venetoclax When Given in Combination With Ponatinib and Dexamethasone (Phase I)
时间窗: Up to 1 year
MTD is defined as the highest dose level where a dose limiting toxicity (DLT) occurs within at most one out of six patients treated. The MTD is defined as the highest dose studied for which the observed incidence of DLT is less than 33%. Frequencies of toxicities will be tabulated according to the National Cancer Institute (NCI) Common Toxicity Criteria. Patients will be continued to be followed for one year for evidence of late toxicity.
Number of Participants With a Response Complete Response (CR) + CR With Incomplete Count Recovery (CRi)
时间窗: 9 weeks
Overall response rate, defined as the rate or complete response (CR) + CR with incomplete count recovery (CRi). Complete Remission (CR): Normalization of the peripheral blood and bone marrow with 5% or less blasts in normocellular or hypercellular marrow with a granulocyte count of 1 x 10\^9/L or above, and platelet count of 100 x 10\^9/L. Complete resolution of all sites of extramedullary disease is required for CR. Complete remission without recovery of counts (CRi): Peripheral blood and marrow results as for CR, but with incomplete recover of counts (platelets \< 100 x 10\^9/L; neutrophils \< 1 x 10\^9/L).
Event Free Survival (EFS)
时间窗: Monthly up to 5 years, 11 months and 7 days
Time from date of treatment start until the date of failure or death from any cause.
