Drug: aprepitant

On day 1, the subject will receive a total daily dose of oral dexamethasone 12mg, oral ondansetron 24mg, and oral aprepitant 125mg. On days 2 to THE LAST DAY OF THE MODERATELY-HIGH TO HIGHLY EMETOGENIC CHEMOTHERAPY, subjects will receive a total daily dose of oral dexamethasone 12mg, oral ondansetron 24mg, and oral aprepitant 80mg. All anti-emetics should be give one hour before starting chemotherapy administration.

FOR TWO DAYS AFTER RECEIVING CHEMOTHERAPY, the subject will be prescribed oral dexamethasone 4mg every 12 hours and oral aprepitant 80 mg every day.

FOR RESCUE, the subject will be prescribed prochlorperazine 10 mg oral every 4 hours as needed for nausea and prochlorperazine 10 mg intravenous every 4 hours as needed for vomiting.

In the studies leading to aprepitant's approval, subjects received only one dose of highly emetogenic chemotherapy. Campos et al studied subjects who received their first course of cisplatin containing chemotherapy that included a cisplatin dose 70mg/m2 and reported that aprepitant in addition to granisetron and dexamethasone increased the number of subjects without acute or delayed emesis (p<0.01). A similar study done by Poli-Bigelli et al indicated that adding aprepitant to a standard antiemetic regimen increased the percentage of subjects without emesis and using rescue therapy during the acute phase (83% to 69%; p < 0.001). Adding aprepitant also increased the percentage of subjects with no emesis or use of rescue medications in the delayed phase (68% vs. 47%, p<0.001). Although these studies demonstrate the benfits of aprepitant for a one day chemotherapy regimen, the benefits of adding aprepitant to current standard antiemetic therapy (dexamethasone plus a serotonin receptor antagonist) in subjects receiving multiple days of moderately-high to highly emetogenic chemotherapy have not been examined within a clinical study. We hypothesize that aprepitant with dexamethasone and a serotonin receptor antagonist from days one to two days after finishing chemotherapy will decrease nausea for subjects receiving chemotherapy regimens that include multiple days of treatment with moderately-high to highly emetogenic chemotherapy.
