Inclusion Criteria:

          1. Pathologically confirmed AML or CLL, otherwise eligible for VEN-containing therapy at
             Screening

               1. Newly diagnosed patients with AML deemed ineligible for intensive induction
                  chemotherapy (age 75 and older or < 75 years of age with comorbidities that
                  preclude the use of intensive induction therapy) eligible to receive VEN at
                  Screening. VEN may be combined with azacitidine or decitabine at the discretion
                  of the treating Investigator.

               2. Relapsed/refractory CLL eligible to receive single-agent VEN or VEN in
                  combination with rituximab at Screening.

               3. Newly-diagnosed CLL eligible to receive VEN in combination with obinatuzumab at
                  Screening.

          2. Patients who have been receiving stable doses of VEN for at least 5 days prior to
             initiation of PIT add-on therapy.

          3. Age ≥ 18 years.

          4. Patients who are already on statins for dyslipidemias are eligible if their previous
             statin is stopped at least 72 hour prior to starting VEN-based therapy; administration
             of other statins is prohibited during the study.

          5. ECOG performance status ≤ 2 at baseline.

          6. Creatinine clearance 30 mL/min or higher; patients assigned to the highest dose level
             of PIT add-on therapy must have creatinine clearance 60 mL/min or higher.

          7. Liver Function tests within the following ranges:

               1. Aspartate aminotransferase (AST) ≤ 3.0 × ULN

               2. Alanine aminotransferase (ALT) ≤ 3.0 × ULN

               3. Bilirubin ≤ 1.5 × ULN (unless elevated bilirubin due to leukemic involvement in
                  the liver or Gilbert's disease)

          8. Ability to understand and willingness to sign the informed consent.

          9. For the duration of the study treatment period and for at least 90 days following the
             last dose of study drug female of childbearing potential (FCBP) who are sexually
             active must agree to employ effective contraceptive methods. Effective contraceptive
             methods include use of hormonal contraception or an intrauterine device (IUD) by the
             female partner, or use of condoms by the male partner. 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.

          4. Patients with AML who received prior therapy other than hydroxyurea including those
             starting hypomethylating therapy for MDS after AML diagnosis.

          5. Patients with acute promyelocytic leukemia are excluded

          6. Patients with known CNS involvement with leukemia are excluded

          7. Patients with active hepatitis B (HBV) or hepatitis C (HCV) infection are excluded.
             Patients with prior HBV or HCV exposure and those on antiviral medications with
             negative HBV or HCV viral loads are eligible, as long as the antiretroviral drugs
             being used do not have significant CYP3A4 interactions.

          8. Patients with uncontrolled HIV are excluded. Patients with known HIV and undetectable
             viral loads are eligible as long as the antiretroviral drugs being used do not have
             significant CYP3A4 interactions.

          9. Patients with a history of allergic reactions attributed to compounds of similar
             chemical or biologic composition to PEN, PIT, or other statins are excluded.

         10. Patients receiving are strong inhibitors or inducers of CYP3A4 within 7 days prior to
             initiation of VEN therapy are excluded. 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).

         11. 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.

         12. Patients with certain uncontrolled intercurrent illness are excluded. These include,
             but are not limited to ongoing or active infection, symptomatic congestive heart
             failure, unstable angina pectoris, cardiac arrhythmia, psychiatric illnesses, or
             social situations that would limit compliance with study requirements.

         13. Patients who are pregnant or breastfeeding are excluded.

         14. Patients who are unable to swallow pills are excluded.

         15. Patients having a malabsorption syndrome or other condition that precludes the
             oral/enteral route of administration are excluded

         16. Patients with an active concurrent malignancy other than CLL or AML are excluded.
             Patients with a history of definitively treated prior malignancy with low risk of
             recurrence, skin cancers that have been excised, or on prolonged adjuvant hormonal
             therapy (ie, for breast or prostate cancer) but are otherwise considered in remission
             are eligible.
