Inclusion Criteria:

Patients diagnosed with acute myeloid leukemia (AML) by World Health Organization (WHO) classification, meeting one of following criteria:

Age 60 or older, newly diagnosed, untreated, who are unwilling to undergo or not candidates for conventional induction chemotherapy with cytarabine/anthracyclines
Age 60 or older with relapsed or refractory disease
Younger adult patients with previously untreated high-risk disease (complex karyotype, inv[3] or t[3;3], t[6;9], monosomal karyotype, therapy-related and secondary disease) that are unwilling to undergo or not candidates for conventional induction chemotherapy with cytarabine/anthracyclines and/or allogeneic stem cell transplantation
Younger patients with refractory/relapsed AML who are otherwise not candidates for allogeneic stem cell transplantation
Patients with extramedullary disease who meet one of the above criteria may be included
Eastern Cooperative Oncology Group (ECOG) performance status =< 2
Patients with co-morbid medical illness, life expectancy attributed to this must be greater than 6 months
The effects of pevonedistat and decitabine on the developing fetus is unknown; for this reason, women of child bearing potential and men must agree to use effective contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for 4 months following duration of study participation; should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately

Female patients must be:

Postmenopausal for at least 1 year before the screening visit, OR
Surgically sterile, OR

If they are of childbearing potential

Agree to practice 1 highly effective method and one 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 [e.g., calendar, ovulation, symptothermal, postovulation methods] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception)

Male patients, even if surgically sterilized (i.e., status post-vasectomy) must:

Agree to practice effective barrier contraception during the entire study treatment period and through 6 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, postovulation methods for the female partner] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception)
Creatinine < 1.5 X institutional upper limit of normal
OR creatinine clearance >= 60 mL/min for patients with creatinine levels above 1.5 X institutional upper limit of normal
Cardiac ejection fraction >= 50%
Albumin > 2.7 g/dL
Total bilirubin =< institutional upper limit of normal (ULN) (except in patients with Gilbert's syndrome; patients with Gilbert's syndrome may enroll if direct bilirubin is =< 1.5 x ULN
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 ULN unless higher levels are related to leukemic infiltration
Hemoglobin > 8 g/dL; patients may be transfused to receive this value; elevated indirect bilirubin due to post-transfusion hemolysis is allowed
All subjects must have the ability to understand and the willingness to sign a written informed consent

The following patients are allowed:

Patients may have been treated for AML or antecedent hematologic disorder with myeloid growth factors, recombinant erythropoietin, thalidomide, lenalidomide, 5-azacitidine or decitabine
Any prior chemo therapy must have been completed >= 2 weeks prior to day 1 of study treatment and the participant must have recovered to eligibility levels from prior toxicity
There is no limit for prior chemo regimens
Patients may have received hematopoietic stem cell transplantation for AML or other diseases
Hydroxyurea is allowed prior to day 1 of study treatment for count control and during cycle 1; the use of hydroxyurea is not allowed beyond completion of cycle 1

Exclusion Criteria:

History of allergic reactions attributed to compounds of similar chemical or biologic composition to pevonedistat or decitabine
Patients have received prior chemotherapy or radiation for AML < two weeks before study enrollment, or those who have not recovered from the adverse events due to agents administered
Females who are both lactating and breastfeeding or who have a positive serum pregnancy test during the screening period or a positive urine pregnancy test on day 1 before first dose of study drug
Patients with additional (other than AML) active malignancies, other than curatively treated carcinoma in situ (CIS) of the cervix, or basal or squamous cell carcinoma of the skin; patients are not considered to have a "currently active" malignancy if they have completed therapy for a prior malignancy and disease free from prior malignancies for > 2 years
