Trial overview

Official title: A Phase I, Randomized, Placebo-Controlled, Four-Way Crossover Study to Evaluate the Effect of Intravenous (IV) Zanamivir on Cardiac Conduction as Assessed by 12-lead Electrocardiogram (ECG) with Moxifloxacin as a Positive Control in Healthy Volunteers
Trial description: Approximately 40 healthy subjects will be enrolled. Each subject will participate in the study for approximately 9 weeks. There will be four treatment sequences with a 5-7 day washout between treatments. Subjects will be admitted to the clinical unit on Day-1 of each dosing period and will remain in the unit until Day 2. Each subject will receive a single dose of each of the four treatments on Day 1 of each treatment period in a randomized fashion. Subjects will be discharged from the clinical research unit after the completion of all assessments on Day 2 of each period and return approximately 5-7 days later for the next dose period. Serial pharmacokinetic samples will be collected for up to 24 hours following each treatment.
