This is a multicenter, randomized, controlled, double-blind, phase III study assessing the efficacy and safety of Olanzapine plus fosaprepitant plus ondansetron and dexamethasone versus fosaprepitant plus ondansetron and dexamethasone in the prevention of chemotherapy-induced nausea and vomiting in patients receiving high emetic risk multi-day chemotherapy. Eligible patients will be randomized to receive either olanzapine plus fosaprepitant standard antiemetic therapy or fosaprepitant standard antiemetic therapy in a 1:1 ratio.
