Arms of the Study
Arm 1
Arm 2
Experimental
Placebo Comparator
Treatment Arm 1 (pimodivir + Standard-of-Care [SOC] treatment)
Treatment Arm 2 (placebo + SOC treatment)
Participants will receive pimodivir 600 milligram (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) along with SOC treatment. Participants who meet all treatment extension criteria as defined in the protocol may receive an additional 5 day course of same treatment as received at study start. The SOC treatment is determined by investigator based on local practice, may include influenza antivirals and/or supportive care only. The choice to use influenza antivirals as part of SOC should be started no later than the day when participants initially receive pimodivir. An influenza antiviral as part of SOC cannot be changed (example, switching one influenza antiviral for another) during either treatment period or extension phase, with the exception that an influenza antiviral may be discontinued in case of suspected adverse event (AE).
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 morning of Day 6) along with SOC treatment. Participants who meet all treatment extension criteria as defined in protocol may receive an additional 5 day course of same treatment as received at study start. The SOC treatment determined by investigator based on local practice, may include influenza antivirals and/or supportive care only. The choice to use influenza antivirals as part of the SOC should be made before randomization. The influenza antiviral should be started no later than day of first study drug intake. An influenza antiviral as part of the SOC cannot be changed (for example, switching one influenza antiviral for another) during either treatment period/extension phase, with the exception that an influenza antiviral may be discontinued in case of a suspected AE.
