• Male or female subjects 18 years or older.

• Patients must have a diagnosis of morphologically documented AML or secondary AML [from prior conditions, such as myelodysplastic syndrome (MDS), or therapy-related AML (t-AML), as defined by World Health Organization (WHO) criteria.

• During the dose-escalation phase, only subjects with relapsed/refractory AML will be eligible.

• During the expansion phase, subjects with relapsed/refractory AML will be eligible OR subjects with newly diagnosed AML unable or unwilling to receive intensive induction chemotherapy will be eligible.

• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.

• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × institutional ULN.

• Creatinine clearance ≥ 30 mL/min (calculated by Cockcroft-Gault formula).

• White blood cell (WBC) count < 25,000/μL before administration of pevonedistat on cycle 1 day 1. (Note: Hydroxyurea may be used to meet this criterion.)

• Prothrombin time (PT) and partial thromboplastin time (PTT) < 1.5 institutional ULN.

• Female subjects who:

• Are postmenopausal for at least one year before the screening visit, OR

• Are surgically sterile, OR

• If they are of childbearing potential:

• Agree to practice one highly effective method and one additional effective (barrier) method of contraception, at the same time, from the time of signing the informed consent through four months after the last dose of study drug (female and male condoms should not be used together), OR

• Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception).

• Male subjects, even if surgically sterilized (i.e., status postvasectomy), who:

• Agree to practice effective barrier contraception during the entire study treatment period from the time of signing the informed consent through and through four months after the last dose of study drug (female and male condoms should not be used together), OR

• Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods for the female partner] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception.)

Exclusion Criteria:

• Acute promyelocytic leukemia.

• Any evidence of spontaneous tumor lysis syndrome (TLS).

• Known hepatitis B surface antigen seropositive or known or suspected active hepatitis C infection.

Note: Patients who have isolated positive hepatitis B core antibody (i.e., in the setting of negative hepatitis B surface antigen and negative hepatitis B surface antibody) must have an undetectable hepatitis B viral load. Patients who have positive hepatitis C antibody may be included if they have an undetectable hepatitis C viral load.
