PURPOSE: This study compares the efficacy and safety of ondansetron alone with that of ondansetron plus dexamethasone in the prevention of emesis induced by high-dose cisplatin (>or = 100 mg/m2).
PATIENTS AND METHODS: This multicenter study used a randomized, double-blind, parallel-group design. Chemotherapy-naive patients were randomized to receive intravenous (IV) ondansetron (Zofran, Cerenex Pharmaceuticals, Research Triangle Park, NC) 0.15 mg/kg for three doses every 4 hours beginning 30 minutes before cisplatin administration either alone or in combination with dexamethasone 20 mg administered 45 minutes before cisplatin. Cisplatin (>or = 100 mg/m2) was administered as a single infusion (<or = 3 hours). Patients were monitored for emetic episodes (EEs), adverse events, and laboratory safety parameters for 24 hours after cisplatin administration.
RESULTS: A total of 275 patients were enrolled. Of these, 245 were assessable for efficacy. Patients who received ondansetron plus dexamethasone had a higher complete antiemetic response rate (61% v 46%, P = .02) and less nausea (posttreatment visual analog scale mean 18.2 v 32.8, P<.001) than did those who received ondansetron alone. The time to the first EE was longer for patients in the group that received ondansetron plus dexamethasone (P = .005). Headache (12%), diarrhea (2%), and abdominal colic (1%) were the most common antiemetic-related adverse events reported. The incidence of adverse events was similar between the treatment groups.
CONCLUSION: IV ondansetron in combination with dexamethasone is safe and more effective than ondansetron alone in the prevention of emesis induced by high-dose cisplatin.
