The purpose of this study is to evaluate the clinical and virologic benefit of pimodivir in combination with Standard-of-Care (SOC) treatment compared to placebo in combination with SOC treatment.
This double-blind (neither researchers nor participants know what treatment participant is receiving) study will evaluate efficacy/safety of pimodivir in combination with SOC treatment versus placebo in combination with SOC treatment in adolescent, adult, and elderly hospitalized participants with influenza A infection. The study will be conducted in 3 phases: screening phase, double-blind treatment period of 5 days (with the possibility to extend treatment period by 5 days for participants who will enter an optional double-blind extension treatment arm), and post treatment follow-up period of 23 days. Study evaluations will include efficacy, pharmacokinetic, biomarkers, safety and tolerability. The duration of participation in study for each participant is 28 days, except for participants receiving extended treatment, for whom study duration will be up to 33 days.
Participants will receive pimodivir 600 mg orally twice daily for 5 days (on Days 1 through 5; for participants who will receive only 1 dose of pimodivir on Day 1 \[evening\], dosing will continue until the morning of Day 6). Participants who meet treatment extension criteria may receive an additional 5 day course of the same treatment as received at study start (on Days 6 through 10).
Participants will receive placebo matching to pimodivir, orally twice daily for 5 days (on Days 1 through 5; for participants who will receive only 1 dose of placebo on Day 1 \[evening\], dosing will continue until the morning of Day 6). Participants who meet treatment extension criteria may receive an additional 5 day course of the same treatment as received at study start (on Days 6 through 10).
Participants may receive SOC treatment as a part of background therapy. The SOC treatment is determined by the investigator based on local practice, and may include influenza antivirals and/or supportive care only. The choice to use influenza antivirals as part of the SOC should be started no later than the day when participants initially receive pimodivir. An influenza antiviral as part of the SOC cannot be changed (for example, switching one influenza antiviral for another) during either the treatment period or extension phase, with the exception that an influenza antiviral may be discontinued in the case of a suspected AE.
