Brief summary

The objective of this study is to investigate the efficacy of olanzapine as compared to neurokinin-1 receptor antagonists (NK1-RAs) in the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients with gynecologic malignancies receiving single day outpatient chemotherapy (carboplatin and paclitaxel) every 3 weeks.

Interventions

DRUGOndansetron

8 mg IV or 16 mg by mouth on day 1 pre-chemotherapy; then 8 mg by mouth twice a day on days 2-4 of chemotherapy

DRUGDexamethasone

DRUGNeurokinin-1 Receptor Antagonist (NK1-RA)

150 mg IV on day 1 pre-chemotherapy

DRUGOlanzapine

5 mg by mouth on days 1-4 of chemotherapy (taken at night)

5-10 mg by mouth, available as needed, every 6 hours, days 1-5
