This phase 2 study ( N = 116) evaluated single-agent vosaroxin, a first-in-class anticancer quinolone derivative, in patients ≥60 years of age with previously untreated unfavourable prognosis acute myeloid leukaemia. Dose regimen optimization was explored in sequential cohorts ( A: 72 mg/m2 d 1, 8, 15; B: 72 mg/m2 d 1, 8; C: 72 mg/m2 or 90 mg/m2 d 1, 4). The primary endpoint was combined complete remission rate (complete remission [ CR] plus CR with incomplete platelet recovery [ CRp]). Common (>20%) grade ≥3 adverse events were thrombocytopenia, febrile neutropenia, anaemia, neutropenia, sepsis, pneumonia, stomatitis and hypokalaemia. Overall CR and CR/ CRp rates were 29% and 32%; median overall survival ( OS) was 7·0 months; 1-year OS was 34%. Schedule C (72 mg/m2) had the most favourable safety and efficacy profile, with faster haematological recovery (median 27 d) and lowest incidence of aggregate sepsis (24%) and 30-d (7%) and 60-d (17%) all-cause mortality; at this dose and schedule, CR and CR/ CRp rates were 31% and 35%, median OS was 7·7 months and 1-year OS was 38%. Overall, vosaroxin resulted in low early mortality and an encouraging response rate; vosaroxin 72 mg/m2 d 1, 4 is recommended for further study in this population. Registered at : # NCT00607997.
