Trial overview

Official title: A retrospective observational chart review study to evaluate the clinical effectiveness of treatment with zanamivir 10 mg/mL solution for infusion in a cohort of intensive care unit-treated (ICU) patients with complicated influenza infection
Trial description: Influenza infection continues to be an important public health priority, with seasonal outbreaks and pandemics causing considerable global morbidity and mortality annually. It is recognized that there are limited options for the treatment of influenza in both adults and children. Neuraminidase inhibitors (NAIs) have been shown to be effective for the treatment of seasonal influenza, but the threat of antiviral drug resistance remains. Furthermore, there is an unmet medical need for participants who are unable to take oral or actively inhaled medications, or where systemic exposure beyond the respiratory tract is required, highlighting the need for intravenous (IV) formulations of effective anti-influenza agents to treat adult and pediatric participants with complicated influenza. This retrospective observational chart review study will be conducted as a specific obligation following the grant of the marketing authorization under exceptional circumstances as stated in Article 14 (8) of Regulation ethics committee (EC) number 726/2004 for Dectova (zanamivir) 10 milligram per milliliter (mg/mL) solution for infusion. The clinical outcomes among complicated influenza participants, admitted to ICU treated with Dectova as part of their routine medical care, will be compared with a concurrent cohort of ICU participants who did not receive this therapy. A propensity score matched approach will be used to compare the primary endpoint of all-cause in-hospital mortality between treatment groups. This study will be conducted in selected countries from the European Union (EU), Norway and Iceland.

  • Historical cohort: Adults, adolescents, children and infants of all ages who were admitted to ICU with influenza illness.
  • Comparative cohort: Adults, adolescents, children and infants of all ages who were admitted to ICU with influenza illness and treated with IV zanamivir as part of their routine medical care, treated with inactive antivirals or not treated at all (treatment may be initiated before or during ICU admission).
  • Historical cohort and comparative cohort: No informed consent given in countries where informed consent for retrospective chart reviews is mandated by local ethics/regulatory requirements.
  • Prior treatment (within 30 days) with an investigational influenza drug therapy.
