Brief Summary:
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.

Primary Outcome Measures :
  1. Maximum tolerated dose (MTD) of venetoclax when given in combination with ponatinib and dexamethasone (Phase I) [ Time Frame: 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.

  2. Overall response rate [ Time Frame: 9 weeks ]
    Overall response rate, defined as the rate or complete response (CR) + CR with incomplete count recovery (CRi)

Secondary Outcome Measures :
  1. Rate of minimal residual disease negativity assessed by polymerase chain reaction (PCR) for BCR-ABL transcripts [ Time Frame: 9 weeks ]
  2. Proportion of patients proceeding to allogeneic stem cell transplant (ASCT) a [ Time Frame: Up to 1 year ]
  3. Overall survival (OS) [ Time Frame: From treatment initiation to death or last follow-up, assessed up to 1 year ]
    Kaplan-Meier curves will be used to estimate unadjusted OS distribution.

  4. Relapse-free survival (RFS) [ Time Frame: Up to 1 year ]
    Kaplan-Meier curves will be used to estimate unadjusted RFS distribution.

  5. Incidence of adverse events evaluated according to NCI Common Toxicity Criteria [ Time Frame: Up to 1 year ]
    Toxicity type, severity, and attribution will be summarized for each patient using frequency tables.

  6. Median time to allogeneic stem cell transplant (ASCT) [ Time Frame: Up to 1 year ]
