Efficacy and Safety Study of Fosaprepitant (MK-0517) Plus Ondansetron Versus Ondansetron Alone for the Prevention of Chemotherapy-Induced Nausea and Vomiting in Pediatric Participants (MK-0517-044)

• Status: Terminated
• Trial end date: 2017-02-24
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to evaluate the efficacy and safety of fosaprepitant (MK-0517) plus ondansetron versus ondansetron alone for the prevention of chemotherapy-induced nausea and vomiting (CINV) in pediatric participants scheduled to receive chemotherapeutic agent(s) associated with moderate or high risk of causing emesis (vomiting), or chemotherapy agent(s) not previously tolerated due to vomiting. The primary hypothesis is that a single dose of fosaprepitant in combination with ondansetron provides superior control of CINV compared to ondansetron alone as measured by the percentage of participants with a Complete Response (no vomiting, no retching, and no use of rescue medications) in the delayed phase (>24 to 120 hours) following initiation of emetogneic chemotherapy in Cycle 1.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Merck Sharp & Dohme Corp.
• Treatments: Aprepitant; BB 1101; Dexamethasone; Dexamethasone 21-phosphate; Dexamethasone acetate; Fosaprepitant; Ondansetron; Serotonin 5-HT3 Receptor Antagonists
