Description of intervention(s) / exposure
Treatment: Drugs - Baloxavir Marboxil
Other interventions - Placebo

Experimental: Baloxavir Marboxil - Participants will receive at least two doses of baloxavir marboxil on Days 1 and 4. A third dose of Baloxavir will be given on Day 7 for participants who have not improved according to protocol defined criteria on Day 5.

Study treatment will be given in combination with SOC NAI (i.e., oseltamivir, zanamivir, or peramivir) in accordance with local clinical practice.

Placebo comparator: Placebo - Participants will receive at least two doses of placebo on Day 1 and 4. A third dose of placebo will be given on Day 7 for participants who have not improved according to protocol defined criteria on Day 5.

Study treatment will be given in combination with SOC NAI (i.e., oseltamivir, zanamivir, or peramivir) in accordance with local clinical practice.


Treatment: Drugs: Baloxavir Marboxil
Baloxavir marboxil will be administered as a weight-based dose on Days 1 and 4. A third dose will be given on Day 7 for participants who have not improved according to protocol defined criteria on Day 5.
