Emend for Multiple-day Emetogenic Chemotherapy
The purpose of the study is to assess the effect of Emend (aprepitant) on nausea and vomiting associated with chemotherapy. Chemotherapy commonly causes nausea and vomiting and this affects patients' quality of life and attitudes toward treatment. Although nausea and vomiting associated with chemotherapy has been decreasing due to improved therapy, some patients will still experience this side effect. Therefore, new medications are needed to decrease the amount of nausea and vomiting patients have with chemotherapy. Emend (aprepitant) is a new medication used to treat nausea and vomiting with chemotherapy, but it has only been studied in patients receiving only one dose of chemotherapy that makes most people sick. However, there is little experience with this medication in patients receiving multiple days of chemotherapy that causes nausea and vomiting.

Drug: aprepitant, ondansetron, dexamethasone
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 benefits 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.
