Azacytidine and Lymphocytes in Relapse of AML or MDS After Allogeneic Stem Cell Transplantation.

"On day 1 of cycle 2, 4 and 6 of Azacytidine, patients will be infused with donor lymphocytes (ideally on day 1 but in case of organizational problems, DLI can be administered until day 5) .~* Patients with a sibling donor will receive:~* 5x10exp7 CD3+/kg on day 1 of cycle 2~* 5x10exp7 CD3+/kg on day 1 of cycle 4~* 10x10exp7 CD3+/kg on day 1 of cycle 6~* Patients with an unrelated donor will receive:~* 1x10exp7 CD3+/kg on day 1 of cycle 2~* 5x10exp7 CD3+/kg on day 1 of cycle 4~* 10x10exp7 CD3+/kg on day 1 of cycle 6"

"* Cycle 1: Subcutaneous administration of 100mg/m2/day for 5 days.~* Cycle 2: Subcutaneous administration of 35mg/m2/day for 5 days. Cycles will be administered every 28 days.~All patients will receive at least 6 cycles of Azacytidine except if progression requests additional disease-related treatment such as hydroxyurea or other chemotherapeutic agents. In such cases, the patient will be excluded from the study and only disease status and survival status will be reported during the 3-year follow-up period. In case of complete remission after cycle 5, 2 additional cycles will be administered after achievement of complete remission.~In case of stable disease or partial response, Azacytidine will be continued until progression.~In case of disease progression after cycle 6, Azacytidine will be stopped."
