These are subjects who are newly diagnosed subjects with AML who are ineligible for intensive induction chemotherapy, relapsed/refractory CLL or newly diagnosed CLL.

Primary Outcome Measures :
  1. Maximum Tolerated Dose for PIT administered with VEN-containing Standard of Care (SOC) regimens [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    Determination of the maximum tolerated dose (MTD) will be utilized to evaluate the safety and tolerability of adding to PIT to treatment with stable doses of VEN ± anti-CD20 antibodies (patients with CLL) or VEN with hypomethylating agents (patients with AML).

  2. Recommended Phase 2 Dose for PIT administered with VEN-containing SOC regimens [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    Determination of the recommended Phase 2 dose (RP2D) will be utilized to evaluate the safety and tolerability of adding to PIT to treatment with stable doses of VEN ± anti-CD20 antibodies (patients with CLL) or VEN with hypomethylating agents (patients with AML).

  3. Identifying Dose Limiting Toxicities (DLTs) for PIT administered with VEN-containing SOC regimens [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    To evaluate the safety and tolerability of administering PIT in combination with VEN-containing SOC in patients with AML or CLL .

  4. Identifying overall Adverse Event Profile of PIT when given with VEN-containing SOC regimens [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    To evaluate the adverse events are based on the CTCAE (NCI Common Terminology Criteria for Adverse Events) Version 5.0.

  5. Complete Response Rate [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    Primary efficacy endpoint is the complete response rate of subjects who receive PIT when given with VEN-containing SOC regimens. The 2018 International Working Group for Chronic Lymphocytic Leukemia (iwCLL) and 2017 European LeukemiaNet (ELN) definitions of Complete Response (CR) will be utilized to determine the CR rate.


Secondary Outcome Measures :
  1. Partial Response Rates [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    Secondary efficacy endpoints are the rates for the other response categories of subjects who receive PIT when given with VEN-containing SOC regimens. The 2018 International Working Group for Chronic Lymphocytic Leukemia (iwCLL) and 2017 European LeukemiaNet (ELN) definitions of Partial Response (PR), Stable Disease (SD) and Progressive Disease (PD) will be utilized to determine the rates for each of these categories.

  2. Stable Disease Rates [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    Secondary efficacy endpoints are the rates for the other response categories of subjects who receive PIT when given with VEN-containing SOC regimens. The 2018 International Working Group for Chronic Lymphocytic Leukemia (iwCLL) and 2017 European LeukemiaNet (ELN) definitions of Partial Response (PR), Stable Disease (SD) and Progressive Disease (PD) will be utilized to determine the rates for each of these categories.

  3. Progressive Disease Rates [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    Secondary efficacy endpoints are the rates for the other response categories of subjects who receive PIT when given with VEN-containing SOC regimens. The 2018 International Working Group for Chronic Lymphocytic Leukemia (iwCLL) and 2017 European LeukemiaNet (ELN) definitions of Partial Response (PR), Stable Disease (SD) and Progressive Disease (PD) will be utilized to determine the rates for each of these categories.

  4. Percentage of Responders [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    Responders are defined as individuals who either received a CR or PR. Responders = CR+PR.

  5. Number of Participants with Abnormal Laboratory Values and/or Adverse Events that Are Related to Treatment [ Time Frame: From the start date of treatment until 30 days after removal of treatment due to disease progression, toxicity, delay of treatment, or withdrawal of treatment, whichever came first, an average of 2 years. ]
    Changes in safety status, such as Eastern Cooperative Oncology Group (ECOG), performance status, vital signs and laboratory assessments throughout treatment through the trial.


Other Outcome Measures:
  1. Composite of PK parameters of VEN and PIT summarized by PIT dose level [ Time Frame: Samples will be collected at the following timepoints: Pre-VEN dose during screening, Cycle 1 Day 1 Pre-VEN and PIT dose, Cycle 1 Day 1 Post dose sampling at 1, 2, 4, 8, 24 hours after first PIT dose. Each cycle is 28 days. ]
    Change in PK parameters from baseline to Cycle 1 to determine if concomitant administration of PIT affects concentrations of VEN when given in combination with PIT.

  2. Composite of dynamic BH3 profiling in priming of ex vivo AML and CLL specimens [ Time Frame: Samples will be collected for BH3 profiling at the following timepoints: prior to initiation of VEN treatment, Cycle 1 Day 1 Pre-PIT dose and predose Cycle 1 Day 2. Each cycle is 28 days. ]
    BH3 profiling on pretreatment and post-treatment bloods samples to assess whether add on treatment with PIT increases apoptotic priming. In dynamic BH3 profiling, the degree of mitochondrial outer membrane permeabilization (MOMP) after exposure to drug is compared to the untreated baseline to quantify the change in priming or induced by exposure to a drug.

An FCBP is a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months).
  10. For the duration of the study treatment period and for at least 90 days following the last dose of study drug, male patients must agree to use effective contraceptive methods during sexual contact with a female of childbearing potential (FCBP) and must agree to refrain from semen or sperm donation during the same timeframe.

Exclusion Criteria:

  1. Patients who are receiving any investigational agents during the previous 30 days or at any time during the study.
  2. Patients who have previously received VEN.
  3. Patients who satisfy any of the contraindications for PIT.

As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product. An exception to this is made for patients with AML who require anti-fungal therapy with appropriate dose reduction in VEN (see Section 5.10.2.3).
  12. Patients who have consumed grapefruit, grapefruit juice or Seville oranges within 72 hours of initiation of VEN therapy. Consumption of grapefruit, grapefruit juice, Seville oranges, or orange marmalade should be avoided for the duration of the study, as these affect CYP3A4 activity.
