Abstract

Background: The granisetron transdermal delivery system (GTDS) has been demonstrated effectiveness in the control of chemotherapy-induced nausea and vomiting (CINV) in previous studies. This is the first phase III study to evaluate the efficacy and tolerability of GTDS in patients receiving moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC) in China.
Methods: A total of 313 patients were randomized into the GTDS group (one transdermal granisetron patch, 7 days) or the oral granisetron group (granisetron oral 2 mg/day, ≥2 days). The primary endpoint was the percentage of patients achieving complete control (CC) from chemotherapy initiation until 24 h after final administration (PEEP). Chi-square test and Fisher’s exact test were used for statistical analysis.
Results: Two hundred eighty-one patients were included in the per protocol analysis. During PEEP, CC was achieved by 67 (47.52%) patients in the GTDS group and 83 (59.29%) patients in the oral granisetron group. There was no statistical significance between the groups (P=0.0559). However, the difference of the CC percentage mainly occurred on the first day of chemotherapy between the groups. The CC was 70.13% on day 1 in the GTDS group, which was significantly lower than that of 91.03% in the oral granisetron group in the full analysis set. In the following days of chemotherapy, the CC was similar between the groups. In terms of cisplatin-contained regimen and female, there was statistical significance between the groups. Both treatments were well tolerated and safe. The most common adverse event was constipation.
Conclusions: GTDS provided effective and well-tolerated control of CINV in Chinese patients, especially to non-cisplatin-contained regimen.
