BLAST MRD AML-2: BLockade of PD-1 Added to Standard Therapy to Target Measurable Residual Disease in Acute Myeloid Leukemia 2- A Randomized Phase 2 Study of Anti-PD-1 Pembrolizumab in Combination With Azacitidine and Venetoclax as Frontline Therapy in Unfit Patients With Acute Myeloid Leukemia

Inclusion Criteria: * Newly diagnosed and pathologically-confirmed, previously untreated AML as defined by World Health Organization (WHO) criteria. Bone marrow biopsy, or aspirate or peripheral blood that were obtained up to 3 weeks before signing consent are allowed for purposes of confirming AML diagnosis for eligibility purposes. Secondary AML arising from prior myelodysplastic syndrome (MDS), as long as they have not received more than full cycle of hypomethylating agent therapy for MDS, and therapy related (t)-AML are also allowed. AML arising from antecedent hematologic disorders defined as prior MDS, myeloproliferative neoplasm (MPN), or aplastic anemia are allowed. Note 1: Patients must have evidence of bone marrow involvement on aspirate or biopsy. Patients with only extramedullary disease and no bone marrow involvement will be excluded. Note 2: Every effort should be made to get an aspirate for central flow assessment at screening and all subsequent required time points, but in cases where an aspirate cannot be collected-including dry taps-the patient will not be excluded and assessments will be performed on peripheral blood (PB) which should be collected at every time that bone marrow (BM) is collected. Note 3: Some patients with AML require initiation of therapy quickly after diagnosis, and full metaphase karyotype results in some centers can take 2-3 weeks to result. To avoid this issue being an impediment to accrual to study or to cause delays in initiation of…
