Randomized Controlled Trial Multicenter Study
Ramosetron Versus Ondansetron in Combination With Aprepitant and Dexamethasone for the Prevention of Highly Emetogenic Chemotherapy-Induced Nausea and Vomiting: A Multicenter, Randomized Phase III Trial, KCSG PC10-21.
A combination of serotonin receptor (5-hydroxytryptamine receptor type 3) antagonists, NK-1 receptor antagonist, and steroid improves the complete response (CR) of chemotherapy-induced nausea and vomiting (CINV) in cancer patients. Ramosetron's efficacy in this triple combination regimen has not been investigated. This prospective, multicenter, single-blind, randomized, phase III study compares a combination of ramosetron, aprepitant, and dexamethasone (RAD) with a combination of ondansetron, aprepitant, and dexamethasone (OAD) to prove the noninferiority of RAD in controlling highly emetogenic CINV. ⋯ RAD is as effective and tolerable as OAD for CINV prevention in patients receiving highly emetogenic chemotherapy. Ramosetron could be considered one of the best partners for aprepitant.
