Efficacy Assessments: 
Primary Endpoint: 
Complete response (CR) (no emetic episode and no rescue medication) during the first 
24 hours after chemotherapy. 
Safety Assessments: 
Safety assessments include the recording and assessing of all adverse events (AEs), vital 
signs, physical examinations (PE), clinical laboratory parameters, 12-lead 
electrocardiogram (ECG), buccal application site evaluation at 0.5 hour (for all subjects),
24 hours (for all subjects) post-dose and at Visit 4 (day 8 for PK subgroups, day 6-8 for 
non-PK subgroups). 
Analysis Sets: 
The full analysis set (FAS) is defined as all randomized patients who received the study 
medication and at least chemotherapy. The analysis based on the FAS is considered as 
primary analysis for all efficacy parameters. 
The per-protocol (PP) set is defined as all patients who completed Day 2 (primary 
endpoint) and who is compliant with the study protocol. 
Pharmacokinetic set (PKS) is defined as all subjects completing the study and for 
whom the pharmacokinetic profile can be adequately characterized. 
The safety set (SS) is defined as all patients treated and have at least one safety 
assessment after treatment. "Patients treated" is defined as any patient who received any 
study medication (palonosetron). 
Pharmacokinetic: 
Parameters: AUC0-t, AUC0-inf, Cmax, Residual area, Tmax, T½ el, and kel. 
Statistical Methods: 
Efficacy: 
The primary analysis will be summarized by treatment arm. The number and 
proportion of patients will be presented by frequency table. For the response rate and 
for the difference in response rate between each Palonosetron HCl Buccal Film group 
and IV palonosetron group, 95% confidence interval (CI) will be provided. 
For the CR rate at 24 h, analyses will be carried out for both FAS and PP population; 
the other parameters will be analyzed only for FAS population. 
The subgroups will be analyzed based on FAS for the primary efficacy by age, gender, 
chemotherapy history, ethanol use, history of pregnancy-related morning sickness, 
history of motion sickness. The between-group treatment effect (with a nominal 95% 
CI) for the primary endpoint will be estimated within each category. 
Safety: 
The analysis of safety will be performed for the safety set. The result will be 
interpreted in a descriptive manner. Incidence of AEs will be calculated overall, by 
system organ and by preferred term. 
Physical examination, vital signs, 12-lead electrocardiogram and application site 
evaluation data will be listed and summarized. For vital signs, differences will be 
calculated compared to baseline. 
Laboratory data will be analyzed and described considering the age and/or gender 
dependent normal ranges of the local laboratory. Laboratory data will be summarized and 
listed. Marked abnormalities and assessments concerning clinical relevance for abnormal 
values will be included. Shift tables will be used for vital signs and laboratory data to 
evaluate categorical changes with respect to normal ranges.
