Nivolumab in AML in Remission at High Risk for Relapse

Inclusion Criteria:

Patients with AML in remission (defined as CR, CR with incomplete platelet recovery -CRp-, CR with incomplete hematologic recovery -CRi-, or partial remission defined as a bone marrow with < 10% blasts after therapy with or without hematologic recovery)
High risk for relapse defined as: 1st CR with high risk features for relapse (including history of prior malignancy treated with chemotherapy or radiotherapy, or history of myelodysplastic syndrome, myeloproliferative disorder, chronic myelomonocytic leukemia, myelodysplastic syndrome [MDS]/myeloproliferative neoplasm [MPN] or other hematologic malignancy thought to have evolved to AML [i.e., secondary AML, (sAML)]; high risk cytogenetics at diagnosis; fms-related tyrosine kinase 3 [FLT3] mutated at diagnosis; or presence or minimal residual disease assessed by polymerase chain reaction [PCR], cytogenetics, and/or flow cytometry at time of enrollment) 2nd CR regardless of disease characteristics at the time of diagnosis
Have received induction chemotherapy and at least one cycle of consolidation chemotherapy; patients should have achieved a CR within 12 months of enrollment onto protocol
No further chemotherapy or stem cell transplant (SCT) planned at the time of enrollment
Creatinine =< 1.5 x upper limit of normal (ULN)
Serum bilirubin =< 1.5 x ULN
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x ULN
Eastern Cooperative Oncology Group (ECOG) performance status =< 2
Females of childbearing potential must have a negative serum or urine beta human chorionic gonadotropin (b-hCG) pregnancy test result within 24 hours prior to the first dose of treatment and must agree to use an effective contraception method during the study and for 23 weeks after the last dose of the study drug; females of non-childbearing potential are those who are postmenopausal greater than 1 year or who have had a bilateral tubal ligation or hysterectomy
Males who have partners of childbearing potential must agree to use an effective contraceptive method during the study and for 31 weeks following the last dose of study drug
Patients or their legally authorized representative must provide written informed consent

Exclusion Criteria:

History of another primary invasive malignancy that has not been definitively treated or in remission for at least 2 years; patients with non-melanoma skin cancers or with carcinomas in situ are eligible regardless of the time from diagnosis (including concomitant diagnoses)
Any major surgery, radiotherapy, chemotherapy, biologic therapy, immunotherapy, experimental therapy within 2 weeks prior to the first dose of the study drugs
Patients with any other known concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes; cardiovascular disease including congestive heart failure New York Heart Association [NYHA] class III or IV, myocardial infarction within 6 months, and poorly controlled hypertension; chronic renal failure; or active uncontrolled infection) which, in the opinion of the investigator could compromise participation in the study
Patients unwilling or unable to comply with the protocol
Patients who are on steroids (> 10 mg/day or equivalent) or immune suppression medications
Patients with autoimmune diseases (e.g., rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [e.g., Wegener's granulomatosis])
Patients with a history of inflammatory bowel disease such as Crohn's disease and ulcerative colitis

Current therapy with other systemic anti-neoplastic or anti-neoplastic investigational agents
Females who are pregnant or lactating
Patients with history of previous immunomodulatory therapy (not including lenalidomide or thalidomide)
