Brief summary: The investigators hypothesize that the combination of Pevonedistat/Low-Dose Cytarabine (LDAC) therapy will be tolerable, that a recommended phase 2 dose of Pevonedistat in combination with LDAC will be identified, and that the combination therapy will show evidence of clinical activity in adult patients with Relapsed/Refractory Acute Myelogenous Leukemia (AML) and Advanced Myelodysplastic Syndromes (MDS).


Eligibility criteria: Inclusion Criteria:

A. Confirmed diagnosis of one of the following:

1. Relapsed/refractory Acute Myelogenous Leukemia (AML) where no alternative life prolonging therapy exists. Treatment naïve patients may also be considered eligible if in the opinion of the investigator, these patients are unlikely to benefit from alternative therapy (eg conventional chemotherapy, hypomethylating agents).
2. Relapsed/refractory Myelodysplasic Syndrome (MDS) following at least two courses of a hypomethylating agent (eg azacitidine or decitabine). Patients intolerant of hypomethylating agents (irrespective of the number of cycles administered) will also be considered eligible. MDS eligibility limited to patients with intermediate, high or very high risk based on IPSS-R.

B. Adult male or female patients 18 years of age or older.

C. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2

D. Patients must satisfy the following laboratory criteria:

1. Albumin \> 2.7 g/dL
2. Total bilirubin ≤ upper limit of normal (ULN) except in patients with Gilbert's syndrome. Patients with Gilbert's syndrome may enroll if direct bilirubin ≤1.5 x ULN of the direct bilirubin
3. Alanine transaminase (ALT) and Aspartate transaminase (AST) must be ≤ 2.5 × ULN
4. Creatinine 1.5 x ULN or calculated creatinine clearance \> 50ml/min
5. Hemoglobin \> 8 g/dL (prior red blood cell (RBC) transfusion allowed). Patients may be transfused to achieve this value. Elevated indirect bilirubin due to post-transfusion hemolysis is allowed.
6. White blood cell (WBC) count \< 50,000/µL before administration of PEVONEDISTAT on Cycle 1 Day 1. Note: Hydroxyurea may be used to control the level of circulating leukemic blast cell counts to not lower than 10,000/µL during the study.

E. Suitable venous access to allow for all study related blood sampling (safety and research).

F. Estimated life expectancy, in the judgment of the Investigator, which will permit receipt of at least 6 weeks of treatment.

G. Voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.

H. Female patients who:

1. Are postmenopausal (see Appendix for definition) for at least 1 year before the screening visit, OR
2. Are surgically sterile, OR
3. If they are of childbearing potential:

   * Agree to practice 1 highly effective method and 1 additional effective (barrier) method of contraception, at the same time, from the time of signing the informed consent through 4 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 \[eg, calendar, ovulation, symptothermal, postovulation methods\] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception).

I. Male patients, even if surgically sterilized (ie, status postvasectomy), who:

1. Agree to practice effective barrier contraception during the entire study treatment period and through 4 months after the last dose of study drug (female and male condoms should not be used together), OR
2. Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence \[eg, calendar, ovulation, symptothermal, postovulation methods for the female partner\] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception).

J. Able to undergo bone marrow aspiration at screening.
