| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The objectives of this study are to investigate the efficacy and safety of a single intravenous (IV) dose of palonosetron (0.025 mg, 0.050 mg or 0.075 mg) versus placebo for the prevention of PONV from 0 to 24 hours and 24 to 72 hours in the postoperative period in female inpatients undergoing elective gynecological or breast surgery with general anesthesia. |

| E.3 | Principal inclusion criteria |
| Female, 18 years of age or older, American Society of Anesthesiologists (ASA) physical status 1 to 3, inpatients undergoing elective gynecological or breast surgery under general anesthesia that is expected to last a minimum of 1hour and requires hospitalization of at least 72hours. Patients must provide written informed consent and have at least one of the two following PONV risk factors: 1) history of PONV and/or currently prone to motion sickness; 2) non-smoking status. Scheduled to receive nitrous oxide as part of the maintenance phase of the anesthesia. |
|
| E.4 | Principal exclusion criteria |
Any drug with potential antiemetic efficacy within 24hours prior to anesthetic procedure. Enrollment in a previous study with palonosetron. Any vomiting, retching, or nausea in the 24hours preceding anesthesia. Body mass index>40. Known hypersensitivity/contraindication to 5-hydroxytryptamine subreceptor 3 (5-HT3) antagonists, or study drug excipients.

| E.5 End points |
| E.5.1 | Primary end point(s) |
The two co-primary efficacy endpoints are
(1) to compare palonosetron (0.025mg, 0.050mg or 0.075mg) with placebo on Complete Response (CR) (defined as no emetic episode and no rescue medication) at 0-24hours, i.e. during the 24-hour postoperative observation period (starting when the patient wakes up and is able to respond to verbal commands postoperatively, e.g., lift head, open eyes, squeeze hand) and
(2) to compare palonosetron (0.025mg, 0.050mg or 0.075mg) with placebo on CR at 24 to 72hours, i.e. during the 24-72 hour postoperative observation period. |
