Nivolumab and Azacitidine with or without Ipilimumab in Treating Patients with Refractory/Relapsed or Newly Diagnosed Acute Myeloid Leukemia

Inclusion Criteria

• ARM 1 SALVAGE COHORT: Patients with AML or biphenotypic or bilineage leukemia who have failed prior therapy; patients with AML should have failed prior therapy or have relapsed after prior therapy will be eligible for Arm 1
• ARM 2 AND 3 SALVAGE COHORT: Patients with AML who have failed up to two prior therapeutic regimens (i.e. salvage 1 or 2 status) will be eligible for Arm 2 relapse cohort; allogeneic stem cell transplant for patients in remission at the time of stem cell transplant will not be considered a salvage regimen; similarly, hydroxyurea if used alone will not be considered a salvage regimen
• ARM 1, 2, AND 3 FRONT LINE COHORTS: Not considered candidates for intensive remission induction chemotherapy at time of enrollment based on EITHER: * >= 75 years of age OR * < 75 years of age with at least 1 of the following: ** Poor performance status (Eastern Cooperative Oncology Group (ECOG) [ECOG]) score of 2-3 ** Clinically significant heart or lung comorbidities, as reflected by at least 1 of: *** Left ventricular ejection fraction (LVEF) =< 50% *** Lung diffusing capacity for carbon monoxide (DLCO) =< 65% of expected *** Forced expiratory volume in 1 second (FEV1) =< 65% of expected *** Chronic stable angina or congestive heart failure controlled with medication ** Liver transaminases > 3 x upper limit of normal (ULN) ** Other contraindication(s) to anthracycline therapy (must be documented) ** Other comorbidity the investigator judges incompatible with intensive remission induction chemotherapy, which must be documented and approved by the principal investigator (PI) Patients with newly diagnosed AML with poor risk karyotype or complex karyotype and/or TP53 deletions/mutations equal or younger than 60 year old will be eligible for the Frontline cohort as well
• Patients with myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML) who received therapy for the MDS or CMML and progress to AML are eligible at the time of diagnosis of AML regardless any prior therapy for MDS or CMML; the World Health Organization (WHO) classification will be used for AML; prior therapy for MDS or CMML will not be considered as a prior therapy for AML, hence such patients will be considered as frontline AML and eligible for the frontline elderly cohort
• Prior therapy with hydroxyurea, chemotherapy, biological or targeted therapy (e.g. FLT3 inhibitors, other kinase inhibitors), or hematopoietic growth factors is allowed as long as within restrictions
• Age >= 18 years
• White blood cell count < 20 x 10^9/L
• ECOG performance status =< 2
• Total bilirubin =< 2 times upper limit of normal (x ULN) (=< 3 x ULN if considered to be due to leukemic involvement or Gilbert’s syndrome)
• Aspartate aminotransferase or alanine aminotransferase =< 2.5 x ULN (=< 5.0 x ULN if considered to be due to leukemic involvement)
• Serum creatinine =< 2 x ULN or glomerular filtration rate (GFR) >= 50
• Patients must provide written informed consent
• In the absence of rapidly progressing disease, the interval from prior treatment to time of initiation of protocol therapy will be at least 2 weeks OR at least 5 half-lives for cytotoxic/noncytotoxic agents; the half-life for the therapy in question will be based on published pharmacokinetic literature (abstracts, manuscripts, investigator brochure’s, or drug-administration manuals) and will be documented in the protocol eligibility document; since the effect of immune checkpoint therapy and hypomethylating agents may be delayed, use of one dose of cytarabine (up to 2 g/m^2) or hydroxyurea for patients with rapidly proliferative disease is allowed before the start of study therapy and during the study treatment; concurrent therapy for central nervous system (CNS) prophylaxis or continuation of therapy for controlled CNS disease is permitted
• Females must be surgically or biologically sterile or postmenopausal (amenorrheic for at least 12 months) or if of childbearing potential, must have a negative serum or urine pregnancy test within 72 hours before the start of the treatment
• Women of childbearing potential must agree to use an adequate method of contraception during the study and until 3 months after the last treatment; males must be surgically or biologically sterile or agree to use an adequate method of contraception during the study until 3 months after the last treatment; adequate methods of contraception include: * Total abstinence when this is in line with the preferred and usual lifestyle of the patient; periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception * Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment; in case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment * Male sterilization (at least 6 months prior to screening); for female patients on the study, the vasectomized male partner should be the sole partner for that patient * Combination of any of the two following ** Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate < 1%), for example hormone vaginal ring or transdermal hormone contraception ** Placement of an intrauterine device (IUD) or intrauterine system (IUS) ** Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository In case of use of oral contraception, women should have been stable on the same pill before taking study treatment * Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception
• Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago; in the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential
• Patients with graft versus host disease (GVHD) active < grade 2 who are on a stable dose of immunosuppressive therapy (tacrolimus, cyclosporine, or other) for > 2 weeks will be included; Note: subjects may be using systemic corticosteroids or topical or inhaled corticosteroids

Exclusion Criteria
