Eligibility Criteria:
Inclusion Criteria:~Cycle 1:~* Is 6 months to 17 years of age at time of study entry~* Is scheduled to receive chemotherapeutic agent(s) associated with moderate, high risk or very high risk of vomiting for a documented malignancy, or a chemotherapy regimen not previously tolerated due to vomiting~* Is expected to receive ondansetron as part of their antiemetic regimen~* If female and has begun menses, must has a negative urine pregnancy test prior to~randomization.

Study Arms:
- Aprepitant Regimen (Type: EXPERIMENTAL): Cycle 1:~Participants 12 to 17 years of age, Day 1: aprepitant 125 mg capsule orally (PO) + ondansetron, Days 2 to 3: aprepitant 80 mg capsule PO. Participants 6 months to \<12 years of age, Day 1: aprepitant powder for suspension (PFS), 3.0 mg/kg (up to 125 mg) + ondansetron, Days 2 to 3: aprepitant PFS, 2.0 mg/kg (up to 80 mg).~Optional Cycles 2-6:~Open-label aprepitant administered in the same manner as in Cycle 1.
- Control Regimen (Type: PLACEBO_COMPARATOR): Cycle 1: Participants 12 to 17 years of age, Day 1: matching placebo for aprepitant 125 mg capsule oral (PO) + ondansetron Days 2 to 3: matching placebo for aprepitant 80 mg capsule PO. Participants 6 months to \<12 years of age, Day 1: matching placebo PFS: 3.0 mg/kg (up to 125 mg) + ondansetron, Days 2 to 3: matching placebo PFS: 2.0 mg/kg (up to 80 mg). Optional Cycles 2-6: Open-label aprepitant administered in the same manner as in Cycle 1.
