Trial overview

Official title: A Randomized, Double-blind, Four-period Crossover Study to Investigate the Effect of Intravenous Ondansetron, a 5-HT3 Antagonist, on Cardiac Conduction as Compared to Placebo and Moxifloxacin in Healthy Adult Subjects
Trial description: Ondansetron, also known as Zofran, is a marketed compound used for the prevention of nausea and vomiting. This study, called a thorough QT study, will characterize the effects of a single intravenous (IV) dose of ondansetron on cardiac repolarization as compared to placebo. Moxifloxacin, a commercially available antibiotic known to cause a mild QT prolongation, will be used as a positive control and will be given orally. The cardiac repolarization will be measured by taking consecutive ECGs on a recording device known as a Holter monitor and measuring the QT interval at specified times. In addition, blood samples will also be taken at specified times and will be used to measure the amount of study medication in the body.
Primary purpose:
Other
Trial design:
Crossover Assignment
Masking:
Double (Participant, Investigator)
Allocation:
Randomized
Primary outcomes:

Change in QTcF after a single dose of Ondansetron given IV over 15 minutes.

Timeframe: Single dosing day at each of the 4 treatment periods with a 7-day washout between each period. The total duration of each subject’s participation in the study, from screening through follow-up will be an average of 11 weeks.

Secondary outcomes:

characterize relationship between changes in ddQTc and plasma concentrations of ondansetron

Timeframe: Single dosing day at each of the 4 treatment periods with a 7-day washout between each period. The total duration of each subject’s participation in the study, from screening through follow-up will be an average of 11 weeks.

characterize relationship between QT interval and plasma ondansetron

Timeframe: Single dosing day at each of the 4 treatment periods with a 7-day washout between each period. The total duration of each subject’s participation in the study, from screening through follow-up will be an average of 11 weeks.

characterize the effect on QTcI and QTcB relative to placebo between the two doses of ondansetron and moxifloxacin

Timeframe: Single dosing day at each of the 4 treatment periods with a 7-day washout between each period. The total duration of each subject’s participation in the study, from screening through follow-up will be an average of 11 weeks.

characterize effect on QT and HR relative to placebo of the two doses of ondansetron and moxifloxacin.

Timeframe: Single dosing day at each of the 4 treatment periods with a 7-day washout between each period. The total duration of each subject’s participation in the study, from screening through follow-up will be an average of 11 weeks.

characterize the pharmacokinetics of ondansetron.

Timeframe: Single dosing day at each of the 4 treatment periods with a 7-day washout between each period. The total duration of each subject’s participation in the study, from screening through follow-up will be an average of 11 weeks.

characterize safety and tolerability of the two doses of ondansetron.

Timeframe: Single dosing day at each of the 4 treatment periods with a 7-day washout between each period. The total duration of each subject’s participation in the study, from screening through follow-up will be an average of 11 weeks.

characterize the pharmacokinetics of moxifloxacin if needed.

Timeframe: Single dosing day at each of the 4 treatment periods with a 7-day washout between each period. The total duration of each subject’s participation in the study, from screening through follow-up will be an average of 11 weeks.
