This open-label Phase I study aims to define the recommended dose for further clinical development the NKR-2 treatment administered concurrently with AZA in treatment-naïve AML/MDS patients not candidates for intensive induction chemotherapy. The treatment consists in six consecutive cycles of AZA, administered at days~to 7 of a 28-day cycle. Patients will be treated with 8 injections of NKR-2 at day 9 and 23 of AZA cycles 2-3-4 and 5.~This Phase I study is divided into three sequential cohorts evaluating three different dose-levels of NKR-2 (1x108, 3x108 and 1x109 NKR-2 per injection) using a 3+3 design. Further patients will be enrolled at the RecD to reach 9 evaluable patients in total at the RecD. The study consists of a screening phase, a treatment administration phase and a follow-up phase divided into treatment follow-up (TFU) and long-term safety follow-up (LTSFU). For each patient who received at least one NKR-~administration, the overall study duration will be 15 years after first NKR-~2 administration. Patients will be asked to complete a total of 54 visits during the treatment administration phase, and 5 visits during the treatment follow-up phase. During the LTSFU, yearly visits will be scheduled (up to Visit Y15).
