Influenza, Human Clinical Trial
Official title:
A Randomized, Double Blinded, Parallel Study to Evaluate the Pharmacokinetics of Zanamivir After Single and Repeated Dose (300 mg and 600 mg) Infusion Administration in Healthy Chinese Adults
Zanamivir is a potent and highly selective inhibitor of the influenza virus neuraminidase. Intravenous (IV) zanamivir is being developed for treatment of hospitalized patients with influenza, especially for those patients who may be in greatest need of parenteral influenza antiviral agents. This study is a pharmacokinetic (PK) study to evaluate the safety/tolerability and pharmacokinetic profiles of IV zanamivir 300 milligrams (mg) and 600 mg in Chinese healthy subjects. Subjects will be randomized to receive either 300 mg or 600 mg IV zanamivir as a single dose followed by repeated dose every 12 hours (h) for 5 days. Subjects will be contacted or will return to study center for a follow-up visit, 7 days after the last dose or withdrawal from the study. Total number of subjects planned for enrollment will be 24 such that approximately 10 subjects complete dosing and critical assessments in each dose cohort. The total duration of the study will be approximately 6 weeks from screening to follow-up.
