Sponsor's own description

The objective of this study is to deliver proof of concept that antifungal prophylaxis can reduce the incidence of Influenza Associated Aspergillosis (IAA) in ICU (intensive care unit) patients with severe influenza. The investigators will perform an interventional non-blinded randomized controlled multicentric proof-of-concept study in patients with severe influenza admitted to the ICU. Patients will be randomized to the posaconazole prophylaxis group or to the SOC (standard of care) group. Oseltamivir will be started at the discretion of the investigator. Patients in the posaconazole group will receive posaconazole prophylaxis for 7 days. addendum: pharmacokinetics of posaconazole as prophylaxis for invasive fungal disease on ICU
