Abstract This phase II trial treated elderly or frail AML patients with single agent subcutaneous azacytidine at 100 mg/m(2), on 5 of 28 days for up to 6 cycles. Treatment was stopped for lack of response, or continued to progression in responders. Primary endpoint was response within 6 months. A response rate >34% was considered a positive trial outcome. From 9/2008-4/2010, 45 patients from 10 centres (median age 74 (55-86) years) were accrued. Patients received 4 (1-21) cycles. Best response was CR/CRi in 8 (18%; 95% CI: 8%-32%.), 0 (0%) PR, 7 (16%) hematologic improvement, 17 (38%) stable disease. Three nonresponding patients stopped treatment after 6 cycles, 31 patients had stopped early and 11 patients continued treatment for 8-21 cycles. Adverse events (grade >III) were infections (13), febrile neutropenia (14), thrombocytopenia (7), dyspnea (6), bleeding (5) and anemia (4 patients). Median overall survival was 6 months. Peripheral blood blast counts, grouped at 30% had a borderline significant association with response (p = 0.07). This modified azacytidine schedule is feasible for elderly or frail AML patients in an outpatient setting with moderate, mainly hematologic, toxicity and response in a proportion of patients, although the primary objective was not reached.
