An Intravenous (IV) Zanamivir Pharmacokinetics (PK) Study in Hospitalized Neonates and Infants With Influenza Infection

An Open Label, Single Arm Study to Evaluate Single and Multiple Dose Pharmacokinetics, Safety and Tolerability, and to Explore Clinical Outcomes of Treatment With Intravenous (IV) Zanamivir in Neonates and Infants Under 6 Months of Age With Confirmed Complicated Influenza Infection

Influenza infection is an important public health priority, with seasonal outbreaks and pandemics causing considerable global morbidity and mortality. The PK, pharmacodynamics (PD), safety and efficacy of IV zanamivir have been evaluated in adults, adolescents and infants more than or equal to (>=)6 months of age with hospitalized influenza in the IV zanamivir global development program. However, antiviral treatment of neonates and infants under 6 months of age hospitalized with influenza infection remains a medical unmet need. Given the immaturity of the immune system at this age, there are no licensed influenza vaccines for children aged less than six months old. As a requirement of the Pediatric Investigation Plan European Union (EU), GlaxoSmithKline (GSK) will be conducting this open-label, multi-center, single arm, post-marketing authorization study to evaluate the PK and also collect safety and tolerability information of IV zanamivir in hospitalized neonates and infants under 6 months of age with confirmed complicated influenza infection. The total duration of study participation for each participant will be up to 24 days, a study treatment period up to 10 days and 14 days post-treatment follow up period. However, for a given participant, the initial 5-day treatment course may be extended for up to 5 additional days if clinical symptoms, participant characteristics or virological tests as assessed by the investigator warrant further treatment.
