Details and patient eligibility

About

The purpose is to evaluate the efficacy of ondansetron oral soluble film plus dexamethasone in preventing chemotherapy-induced nausea and vomiting (CINV) with MEC/HEC chemotherapy in children with solid tumor.

Full description

Complete randomization was used to assign subjects to the experimental group (ondansetron oral soluble film plus dexamethasone) and the control group (ondansetron intravenously plus dexamethasone) in a ratio of 1 to 1. And a specialized software was used to generate random numbers to make a random assignment table.

Experimental:

Participants received the first dose of ondansetron oral soluble film (age-based adjustment) 30 minutes before chemotherapy and equal doses were given 4 hours and 8 hours after the first dose for whom younger than 12 years old while the others should be given 8h hours after the first dose. Ondansetron oral soluble film was administered continuously for two days after chemotherapy according to the administration regimen on the day of chemotherapy. Dexamethasone (weight based) iv/po twice daily and discontinued until 72 hours after chemotherapy.

Placebo Comparator:

Participants received the first dose of ondansetron intravenously (weight-based adjustment) 30 minutes before chemotherapy and equal doses were given 4 hours and 8 hours after the first dose. Ondansetron (po) was given for next continuously two days in the same dose and frequency of administration. Dexamethasone (weight based) iv/po twice daily and discontinued until 72 hours after chemotherapy.

Enrollment: 376 estimated patients

376 participants in 2 patient groups

oral soluble film of ondansetron combined with dexamethasone

Experimental group

Description:

Participants received the first dose of ondansetron oral soluble film (age-based adjustment) 30 minutes before chemotherapy and equal doses were given 4 hours and 8 hours after the first dose for whom younger than 12 years old while the others should be given 8h hours after the first dose. Ondansetron oral soluble film was administered continuously for two days after chemotherapy according to the administration regimen on the day of chemotherapy. Dexamethasone (based on body surface area) iv/po twice daily from day 1 of chemotherapy until 2 days after completion of chemotherapy.
