Overview
The name of this prospective study is a multicenter, open-label, randomized controlled clinical study of the efficacy and safety of Ondansetron Oral Soluble Pellicles for the prevention of delayed nausea and vomiting induced by highly emetogenic chemotherapy.
Description
The aim of this study is to observe the efficacy and safety of ondansetron in delayed nausea and vomiting by its continuous dosing, and it is planned to enroll 184 first-time recipients of highly emetogenic single-day chemotherapy regimens (cisplatin dose 60-75 mg/m2; anthracycline compounds adriamycin ≥ 60 mg/m2 or epothilone ≥ 90 mg/m2 ) who were initiated on a triple combination regimen of fosaprepitant + ondansetron orally soluble film + dexamethasone triple regimen for nausea and vomiting prophylaxis in patients. The primary observation was the incidence and severity of delayed nausea and vomiting in both groups from day 5 after chemotherapy to the second cycle of chemotherapy. The secondary observation indexes include the incidence and severity of delayed nausea in patients in both groups from day 5 after chemotherapy to before the second cycle of chemotherapy; the incidence and severity of anticipatory nausea/vomiting in the second cycle of chemotherapy in both groups; the incidence and severity of nausea/vomiting in patients in both groups on days 1-4 after chemotherapy; and the incidence of adverse events and serious adverse reactions, with a focus on the antiemetic drugs common constipation, headache and other events. This trial was randomized into groups, and the experimental group was preset as group A and the control group as group B. The prevention of nausea and vomiting was carried out with the triple regimen of fosaprepitant (Tanneng, Jiangsu Hausen Pharmaceutical Group Co., Ltd.) + Ondansetron Oral Soluble Pellicles (Aiqisu, Jiangsu Hengrui Pharmaceutical Co., Ltd.) + dexamethasone prior to chemotherapy, and the patients were divided into the treatment group A and the control group B by the use of Ondansetron Oral Soluble Pellicles for continuation of the prophylaxis on the 5-7 days after the chemotherapy.
