What researchers measure

Primary outcomes

  1. Resolution of fever and flu symptoms

    Time to resolution of influenza symptoms defined as all flu symptoms scored as \<=1 and change in viral load (RT-PCR).

    Time frame: Days 1-5

Secondary outcomes

  1. Clinical response

    Proportion of clinical responders on Day 3 and Day 6: defined as no fever (oral temperature \< 38 °C and no subjective fever) AND resolution of influenza illness (all flu symptoms and interference scored as ≤ 1).

    Time frame: Day 3 and Day 6

  2. Proportion of poor responders

    Proportion of poor responders on both Day 3 and Day 6: defined as subjects with fever (oral temperature ≥ 38 °C or any record of subjective fever) OR unresolved influenza illness (1 or more flu symptoms/interferences scored as \> 1).

    Time frame: Day 3 and Day 6

  3. Time to resolution of fever

    Time to bring down a fever (oral temperature \< 38 °C and no subjective fever) and time to return to afebrile state (oral temperature ≤ 37.2 °C and no subjective fever).

    Time frame: Days 1-5

  4. Time to resolution of influenza illness

    Time to resolution of influenza illness (all flu symptoms and interference scored as ≤ 1) as reported by the subject.

    Time frame: Days 1-5

  5. Symptom improvement

    Improvement of influenza symptoms and level of interference of disease during treatment period as reported by the subject.

    Time frame: Days 1-5

  6. OTC medication usage

    Proportion of use of the OTC medication for fever or influenza symptoms.

    Time frame: Days 1-5

  7. Physician visits

    Rate of requirement for additional physician visits within 5 days treatment period.

    Time frame: Days 6-10

  8. Treatment failure

    Rate of treatment failure including hospitalization due to disease progression prior to Day 29.

    Time frame: Days 1-28
