Combination of palonosetron, aprepitant, and dexamethasone as primary antiemetic prophylaxis for cisplatin-based chemotherapy

BackgroundThe purpose of this study was to evaluate the efficacy of combined treatment with the long-acting 5-hydroxytryptamine receptor-3 antagonist, palonosetron, the neurokinin-1 receptor antagonist, oral aprepitant, and dexamethasone as primary antiemetic prophylaxis for cancer patients receiving highly emetogenic cisplatin-based chemotherapy.MethodsChemotherapy-naïve patients received the triple combination of palonosetron (0.25 mg), aprepitant (125 mg on day 1 and 80 mg on days 2 and 3), and dexamethasone (20 mg) from the beginning of highly emetogenic chemotherapy with cisplatin-based (≥50 mg/m2) regimens. The primary endpoint was a complete response (no emetic episodes and no rescue antiemetics) during the days 1–6.ResultsSixty-nine hospitalized patients receiving chemotherapy from September 2012 to October 2014 were analyzed. Complete response of vomiting and nausea-free was achieved in 97.1% and 85.5% of patients in the first cycle, respectively, and 96.7% and 83.6% of patients in the second cycle, respectively. Common adverse events in all 69 patients included constipation (43%), hiccup (26%), and headache (4%).ConclusionThe combination of palonosetron, aprepitant, and dexamethasone as primary antiemetic prophylaxis for cancer patients with highly emetogenic cisplatin-based chemotherapy is effective.
