Efficacy of Aprepitant (Emend®) in Children

Ondansetron 0.15 mg/kg (max 16 mg) IV or PO every 8 hours for at least 3 days, but no longer than 5 days; dexamethasone 0.2mg/kg (max 10 mg) IV or PO daily for at least 3 days, but no longer than 5 days; and aprepitant 3 mg/kg (max 125 mg) PO on day 1, and aprepitant 2 mg/kg (max 80 mg) PO on days 2 and 3 during the first investigational antiemetic cycle. During the next investigational antiemetic cycle, members of this arm will be crossed-over into the placebo arm, where the aprepitant will be replaced by placebo and the dexamethasone dose will be increased to 0.4 mg/kg (max 20 mg) daily.
