Phase 4 Trial to Evaluate the Efficacy and Safety of Sancuso Patch in Chemotherapy-induced Nausea and Vomiting Associated With the Administration of Highly Emetogenic Chemotherapy (HEC)

A Multicenter, Randomized, Open-label, Paralleled-group, Active-controlled, Phase IV Study to Evaluate the Efficacy and Safety of Sancuso Patch (Granisetron) in Chemotherapy-induced Nausea and Vomiting (CINV) Associated With the Administration of Highly Emetogenic (HE) Chemotherapy

This is a multicenter, randomized, open-label, paralleled-group, active-controlled study.

The study is to demonstrate non-inferiority of the Granisetron Transdermal Delivery System (GTDS) efficacy compared with the ondansetron efficacy with regard to Complete Response (CR) of Chemotherapy Induced Nausea and Vomiting (CINV).

Patients scheduled to receive the one cycle of a HE chemotherapy regimen administered for 1-5 days will attend a Screening Visit 2 to 14 days before start of HE chemotherapy. Eligible patients will be randomized to 1 of 2 treatment groups at the Randomization Visit (1 to 2 days prior to HE chemotherapy).

• Sancuso patch
• Zofran inj. + Zofran tab.

The patch will be applied 2days (48-24h) prior to first daily dose of the highly emetogenic chemotherapy regimen and remain in place for 5 days after start of chemotherapy. The patient will be assessed daily until 5days after first chemotherapy administration. Adverse Events (AEs) will be collected until 2 days after the final dose of IP. Non-serious AEs will be followed-up until 2 days after the final dose of IP. Serious adverse events will be followed-up until they are resolved, stable or until the patient is lost to follow-up.

Inclusion Criteria:

1. Male or female aged over 20 yrs
2. Eastern Cooperative Oncology Group performance status 0, 1, 2
3. Life expectancy of ≥ 3 months
4. Assigned to receive a cycle of high emetic (HE) chemotherapy regimen including the daily administration of a cytotoxic regimen with the emetogenic potential of level 5 (Hesketh Classification)
5. Patients who signed the informed consent form

Exclusion Criteria:

5. Any cause for nausea and vomiting other than CINV
6. Any episode of retching, vomiting or uncontrolled nausea in the 72 h period prior to the chemotherapy administration
7. Clinically relevant abnormal ECG parameters at the discretion of the investigator

C. Concomitant Therapy/Medication

7. Drugs known to increase the QTc interval (unless a stable dose for the duration of the study at the discretion of the investigator)

D. Other

1. Patients unlikely to comply with the study protocol (at the discretion of the investigator), e.g. uncooperative attitude, inability to return for follow-up visits and unlikelihood of completing the study
2. The patch adhesion level was not more than 50% on the day of chemotherapy or the patch was not attached within two days before the chemotherapy
