Randomized Controlled Trial Multicenter Study Clinical Trial
Improved prevention of moderately emetogenic chemotherapy-induced nausea and vomiting with palonosetron, a pharmacologically novel 5-HT3 receptor antagonist: results of a phase III, single-dose trial versus dolasetron.
Palonosetron, a highly selective and potent 5-HT(3) receptor antagonist with a strong binding affinity and a long plasma elimination half-life (approximately 40 hours), has shown efficacy in Phase II trials in preventing chemotherapy-induced nausea and vomiting (CINV) resulting from highly emetogenic chemotherapy. The current Phase III trial evaluated the efficacy and safety of palonosetron in preventing acute and delayed CINV after moderately emetogenic chemotherapy. ⋯ A single dose of palonosetron is as effective as a single dose of dolasetron in preventing acute CINV and superior to dolasetron in preventing delayed CINV after moderately emetogenic chemotherapy, with a comparable safety profile for all treatment groups.
