Odansetron and Dexamethasone Alone vs. Odansetron, Dexamethason and Apreptant to Prevent Nausea
Condition: Nausea; Vomiting
MeSH terms: Nausea; Vomiting
Intervention: Standard PO (Zofran + Dexamethason); Aprepitant (MK-869) + Standard PO
Intervention description: Dexamethasone 10 mg (dose blinded) in 50 ml D5W IVPB over 15 minutes daily + ondansetron 8mg PO q 8 hours - repeated qd of the preparative regimen and for 1 day after completion. A placebo capsule will be given daily on each day of the preparative regimen plus 3 days after. Antiemetic therapy will start a minimum of 30 minutes prior to and continued for 24 hours after completion of the preparative regimen.; Dexamethasone 7.5 mg (dose blinded) in 50 ml D5W IVPB over 15 min daily + ondansetron 8mg PO q 8 hours - repeated QD of the preparative regimen and for 1 day after completion. Aprepitant 125mg PO [blinded] will be given a minimum of 30 minutes prior to the preparative regimen on day 1. MK-Aprepitant 80mg PO [blinded] will be given will be given approximately 24 hours later starting on day 2 then each day of the preparative regimen plus 3 days after. Antiemetic therapy will start a minimum of 30 minutes prior to and continued for 24 hours after completion of the preparative regimen.

Summary:

      The purpose of this study is to compare two different treatment protocols for treating nausea
      and vomiting in patients who have undergone bone marrow transplant. Patients will be assigned
      to one of two treatment groups.

      The first group will recieve ondansetron (Zofran) tablets combined with a medicine called
      dexamethasone given IV. Both of these drugs are commercially available.

      Patients in the second treatment consists of the first two drugs, plus a newly approved drug
      known as aprepitant (MK-869, Emend). This combination will be the treatment being tested. The
      combination is approved by the FDA for chemotherapy regimens known to cause a lot of nausea
      and vomiting. It significantly decreases the delayed (more than 24 hours after therapy)
      nausea and vomiting seen with these regimens.
