Phase II, open label, randomized comparative trial of ondansetron alone versus the combination of ondansetron plus aprepitant for the prevention of nausea and vomiting in patients with hematologic malignancies receiving regimens containing high-dose cytarabine
The goal of this clinical research study is to compare the effectiveness of receiving a combination of ondansetron and aprepitant to receiving ondansetron alone in helping to prevent nausea and/or vomiting in patients with AML or HR-MDS who are receiving cytarabine. The safety of this drug combination will also be studied.

Primary: To compare the efficacy and safety of ondansetron continuous infusion alone versus ondansetron continuous infusion plus aprepitant in the prevention of nausea and vomiting in patients with acute myelogenous leukemia (AML), high-risk myelodysplastic syndrome (HR-MDS), chronic myelogenous leukemia (CML) in blast crisis or acute undifferentiated leukemia receiving continuous multi-day chemotherapy with a high-dose cytarabine containing regimen. Secondary: 1. To evaluate the safety of the combination of ondansetron and aprepitant. 2. To compare the frequency and severity of vomiting and nausea between the combination of ondansetron and aprepitant and the ondansetron alone.
