A Pharmacokinetic/Pharmacodynamic Study of Oseltamivir in Immunocompromised Children With Confirmed Influenza Infection

Phase 1
Completed
Conditions
Influenza
Interventions
Registration Number
NCT01715909
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This open-label, randomized, adaptive, 2-arm, multicenter study will evaluate the pharmacokinetics and pharmacodynamics of oseltamivir (Tamiflu) in immunocompromised children, less than (\<) 13 years of age, with confirmed influenza infection. Participants will be randomized to receive either the standard dose or triple dose of oseltamivir orally daily for a minimum of 5 days and up to 20 days. Infants \<1 year of age will be randomized to the standard dose arm only.

GroupInterventionDescription
Oseltamivir: Standard doseOseltamivirParticipants will receive standard dose of oseltamivir capsules or suspension orally for 5 to maximum of 20 days depending on weight. Infants \<1 year of age will receive oseltamivir at a dose of 3 milligrams per kilogram (mg/kg).
Oseltamivir: Triple doseOseltamivirParticipants will receive three times the standard dose of oseltamivir capsules or suspension orally for 5 to maximum of 20 days depending on weight and age. Infants \<1 year will receive standard dose at 3 mg/kg.
