Conditions: Chemotherapy-Induced Nausea and Vomiting (CINV)
Keywords: NK-1 Receptor Antagonist, CINV, Emesis, MEC
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 1015
Healthy volunteers: no

Brief summary:
This study aims to demonstrate that, when given concomitantly with a 5-hydroxytryptamine 3 (5-HT3) antagonist and a corticosteroid, a single 150 mg intravenous (IV) dose of fosaprepitant given on Day 1 is superior to the control regimen of 5-HT3 antagonist and corticosteroid only, in preventing chemotherapy-induced nausea and vomiting (CINV) associated with moderately emetogenic chemotherapy (MEC).

Detailed description:

Arms:
arm 1: On Day 1, participants received fosaprepitant, 150 mg intravenous (IV) infusion, \~30 minutes prior to chemotherapy PLUS dexamethasone 12 mg, orally (PO) \~30 minutes prior to chemotherapy PLUS ondansetron 16 mg total dose: 8 mg PO \~30-60 minutes prior to chemotherapy, followed by 8 mg PO, 8 hours after first dose PLUS dexamethasone placebo, PO \~30 minutes prior to chemotherapy. On Days 2 and 3, participants received ondansetron placebo, PO every 12 hours. Rescue Therapy: For established cases of nausea or vomiting, medications may have been prescribed from these permitted choices: 5-HT3 antagonists (granisetron, dolasetron, tropisetron or ondansetron); phenothiazines (e.g. prochlorperazine, fluphenazine, perphenazine, thiethylperazine, or chlorpromazine); butyrophenones (e.g. haloperidol or droperidol); benzamides (e.g. metoclopramide or alizapride); benzodiazepines; corticosteroids; domperidone. arm 2: On Day 1, participants received fosaprepitant placebo, 150 mL IV infusion, \~30 minutes prior to chemotherapy PLUS dexamethasone 20 mg, PO \~30 minutes prior to chemotherapy PLUS ondansetron 16 mg total dose: 8 mg PO \~30-60 minutes prior to chemotherapy; followed by 8 mg PO, 8 hours after the first dose. On Days 2-3, participants received ondansetron 8 mg, PO every 12 hours. Rescue Therapy: For established cases of nausea or vomiting, medications may have been prescribed from these permitted choices: 5-HT3 antagonists (granisetron, dolasetron, tropisetron or ondansetron); phenothiazines (e.g. prochlorperazine, fluphenazine, perphenazine, thiethylperazine, or chlorpromazine); butyrophenones (e.g. haloperidol or droperidol); benzamides (e.g. metoclopramide or alizapride); benzodiazepines; corticosteroids; domperidone.
