Inclusion Criteria

1.Relapse of AML after allo-HCT from any donor source (matched unrelated donor, mismatched unrelated donor, sibling, haploidentical) using bone marrow or peripheral blood stem cells at 3 months or more after allogeneic HCT. Patients can be re-screened.
2.Cytological or histological evidence of AML relapse including but not limited to bone marrow biopsy, extramedullary site biopsy or cerebrospinal fluid evaluation.
3.No immune suppression for at least 2 weeks prior to screening
4.10% or more donor-derived chimerism measured within 4 weeks prior to day 0
5.Male and female patients aged =18 years
6.ECOG performance status 0, 1, or 2
7.No other superior treatment approach (second allo-HCT) available
8.At least 1 cycle of therapy with the hypomethylating agents decitabine or azacitidine between diagnosis of relapse and screening
9.Written informed consent
10.Ability to understand the nature, significance and consequences of the study and the study-related procedures and to comply with them.

Exclusion Criteria

1.History or active acute GvHD grade III/IV
2.Chronic GvHD requiring systemic immunosuppressive treatment at the time of screening
3.Active autoimmune diseases
4.Active treatment in a clinical study of any investigational agent within 30 days prior day 0 or within 5 half-lives of the study treatment, whichever is greater
5.Mechanical ventilation or patients who have resting O2 saturation <90% by pulse-oximetry, require vasopressors, and/or have NYHA class III or IV heart failure
6.Abnormal liver function tests (serum total bilirubin >1,5 x ULN; or in case of liver infiltration by AML, serum (total) bilirubin > 5 x ULN, serum alanine or aspartate aminotransferase >3 × ULN or in case of liver infiltration by AML, AST and/or ALT > 5 x ULN)
7.Abnormal kidney function tests calculatedcreatinine clearance = 30 ml/min by the Cockcroft-Gault equation)
8.Severe hematological impairment (platelets <10 000/µl, hemoglobin level <8 mg/dl unless attributable to AML infiltration of the BM), there is no lower limit for neutrophil counts because AML relapse leads to low neutrophil numbers and treatment with nivolumab could improve this by eradicating the leukemia
9.Active uncontrolled bacterial, viral or fungal infection
10.Positivity for HIV, Hepatitis B or Hepatitis C at the time of screening
11.Active or latent tuberculosis infection that has developed after allo-HCT
12.Previous or concurrent malignancies within the last 3 years of enrolment except for adequately treated basal cell or squamous cell skin cancer, or any other cancer from which the subject has been disease-free for more than 3 years
13.Uncontrolled hypertension or ventricular arrhythmias
14.Any condition that would, in the investigator's judgment, interfere with full participation in the study, including administration of study drug and attending required study visits; pose a significant risk to the subject; or interfere with interpretation of study data
15.Known allergies, hypersensitivity, or intolerance of the study medication, excipients, or similar compounds
16.Female patients who are pregnant or breast feeding
17.Female patients of child-bearing potential who are not willing to use highly effective methods of contraception during the trial and at least 5 months after the last dose of nivolumab
