Sunesis Announces Publication of REVEAL-1 Trial Results in the British Journal of Haematology
"There remains an acute unmet medical need for new treatment options in AML, including patients 60 years of age and older who are unlikely to benefit from standard induction chemotherapy," stated
The REVEAL-1 study evaluated single-agent vosaroxin in patients ≥60 years of age (n=113) with previously untreated unfavorable prognosis AML. Dose regimen optimization was explored in sequential cohorts (A: 72 mg/m2 on days 1, 8, 15; B: 72 mg/m2 on days 1, 8; C: 72 mg/m2 or 90 mg/m2 on days 1, 4). The primary efficacy endpoint was combined complete remission rate (complete remission [CR] plus CR with incomplete platelet recovery [CRp]). The median age in the study was 75 years and most patients (82%) had 2 or more risk factors (age ≥ 70, antecedent hematologic disease [AHD], ECOG PS=2, or intermediate/unfavorable cytogenetics).
Common (>20%) grade ≥3 adverse events were thrombocytopenia, febrile neutropenia, anemia, neutropenia, sepsis, pneumonia, stomatitis, and hypokalemia. 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 favorable balance of safety and efficacy, with faster hematologic recovery (median 27 days) and lowest incidence of aggregate sepsis (24%) and 30-day (7%) and 60-day (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%.
