Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Time to alleviation of all primary influenza symptoms and fever
Time Frame: 21 days
|
Time from the start of study treatment until alleviation of all primary influenza symptoms (i.e.
cough, sore throat, headache, nasal congestion, body aches and pains, fatigue) and to resolution of fever.
Subjects will be considered to have symptoms alleviated if individual symptoms are no greater than mild and are confirmed to be no greater than mild at least 21.5 hours later.
Similarly, resolution of fever is defined as temperature (oral) measurements to be < 38.0°C (<100.4°F)
for subjects < 65 years old and < 37.8°C (100.0°F) for subjects ≥ 65 years old, and measurements are confirmed at least 21.5 hours later.
For the primary endpoint, the time periods of alleviation/fever resolution must be concurrent for symptoms and temperature.

Measure Description |
Time Frame |

|
Time to alleviation each of the primary influenza symptoms and fever
Time Frame: 21 days
|
Time from the start of study treatment until alleviation of each of the following influenza symptoms (cough, sore throat, headache, nasal congestion, body aches and pains, and fatigue) and to resolution of fever.
Subjects will be considered to have symptoms alleviated if individual symptoms are no greater than mild and are confirmed to be no greater than mild at least 21.5 hours later.
Similarly, resolution of fever is defined as temperature (oral) measurements to be < 38.0°C (<100.4°F)
for subjects < 65 years old and < 37.8°C (100.0°F) for subjects ≥ 65 years old, and measurements are confirmed at least 21.5 hours later.
Additional analyses of symptoms, including assessment of the impact of relevant covariates, will be specified in the Statistical Analysis Plan.
