CCR, conventional care regimen; CI, confidence interval; EFS, event-free survival; HR, hazard ratio; ITT, intention-to-treat; mITT, modified ITT; OS, overall survival; TTF, time to treatment failure.
∗
The mITT population included patients who had an independent confirmation of AML diagnosis, had no major protocol violations, received ≥1 dose of the study drug, and had ≥1 postrandomization efficacy assessment.
