Brief summary:
This study will be an open-label, multi-center, single arm study to evaluate the safety and efficacy of IV zanamivir 600mg twice daily for 5 days in hospitalized subjects with laboratory confirmed influenza infection.

Detailed description:
Adult subjects and adolescent subjects (≥50 kg) with normal renal function will receive 600mg per dose. Subjects with renal impairment will receive an adjusted dose based on calculated creatinine clearance. The initial 5 day treatment course may be extended for up to 5 additional days if viral shedding is determined to be ongoing or if clinical symptoms warrant further treatment with IV zanamivir.

The study duration is approximately 28 days for subjects whose treatment duration is 5 days, and up to approximately 33 days for subjects whose treatment duration is extended to a maximum of 10 days. The study will consist of Pre-dose Baseline Assessments (Day 1), During Treatment Assessments (Days 1 to 5, and up to Day 10), and Follow-up Assessments on the following days: Post-Treatment +2, +5, +9, +16 and +23 Days. For subjects who have been discharged from hospital, the Post-Treatment +2, +5, +9 and +16 Days Assessments can be made by telephone contact.
