    Cmax is the maximum observed plasma concentration. As per planned analysis, results are presented by age groups (65 to less than or equal to [<=] 85 years and 18 to <=64 years).

  2. Minimum Observed Plasma Concentration (Cmin) of Pimodivir [Pre-dose, 1, 2, 4, 6, 8, 10 and 12 hours post-dose on Day 3]

    Cmin is the minimum observed plasma concentration. As per planned analysis, results are presented by age groups (65 to <= 85 years and 18 to <=64 years).

  3. Area Under the Plasma Concentration-time Curve From Time of Administration to 12 Hours After Dosing (AUC [0-12]) of Pimodivir [Pre-dose, 1, 2, 4, 6, 8, 10 and 12 hours post-dose on Day 3]

    AUC (0-12) is the area under the plasma concentration-time curve from time zero to 12 hours after dosing of pimodivir. As per planned analysis, results are presented by age groups (65 to <= 85 years and 18 to <=64 years).

Secondary Outcome Measures

  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious AEs (TESAEs) [Up to 28 Days]

    An adverse event (AE) is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non investigational) product. An AE does not necessarily have a causal relationship with treatment and therefore can be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with use of a medicinal product, whether or not related to that medicinal product. TEAEs were defined as AEs that were reported or worsened on after start of study drug(s) dosing through safety follow-up visit. A serious adverse event (SAE) is any untoward medical occurrence that at any dose resulting in any of following outcomes: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is a suspected transmission of any infectious agent via a medicinal product.

  2. Time to Influenza A Viral Negativity [Up to 14 Days]

    Time to influenza A viral negativity was determined based on quantitative reverse transcription polymerase chain reaction (qRT-PCR). A participant was considered influenza A viral negative at the time point that the first negative nasal midturbinate (MT) swab was recorded (in days). Viral Load Limit of detection (LOD) = 2.18 log10 viral particles per milliliter (vp/mL). Results less than (<) limit of quantification (LOQ) and greater than (>) LOD (target detected) are imputed with 2.12 log10 vp/mL, results <LOD (target not detected) are imputed with 0 log10 vp/mL.

  3. Influenza Viral Load Over Time [Baseline, Days 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 14]

    Influenza viral load over time (Log 10 viral particles per milliliter [vp/mL]) was measured by qRT-PCR. Viral Load LOD = 2.18 log10 vp/mL. Results < LOQ and > LOD (target detected) are imputed with 2.12 log10 vp/mL and results <LOD (target not detected) are imputed with 0 log10 vp/mL.

  4. Rate of Decline in Viral Load [Up to Day 7]

    Rate of decline in viral load (Log10 viral particles per milliliter per day [log10 vp/mL/day]) during treatment was measured by qRT-PCR. Viral Load Limit of quantification (LOQ) = 2.18 log10 vp/mL, LOD = 2.05 log10 vp/mL. Results < LOQ and greater than > LOD (target detected) are imputed with 2.12 log10 vp/mL. Results <LOD (target not detected) are imputed with 0 log10 vp/mL.

  5. Area Under the Plasma Concentration-time Curve (AUC) of Viral Load [Baseline up to Day 8]

    Viral load AUC was determined by qRT-PCR assay of nasal swabs. Viral Load LOQ = 2.18 log10 vp/mL, LOD = 2.05 log10 vp/mL. Results <LOQ and >LOD (target detected) are imputed with 2.12 log10 vp/mL. Results <LOD (target not detected) are imputed with 0 log10 vp/mL.

  6. Percentage of Participants With Influenza Complications [Up to 28 Days]

    Percentage of participants with following Influenza Complications: bacterial pneumonia (culture confirmed where possible), bacterial superinfections, respiratory failure, pulmonary disease (example, asthma, chronic obstructive pulmonary disease [COPD]), cardiovascular and cerebrovascular disease (example, myocardial infarction, congestive heart failure [CHF], arrhythmia, stroke) and all complications were reported.

    FLU-PRO assesses 32 influenza symptoms in each of the following body areas (domains): Nose, Throat, Eyes, Chest/Respiratory, Gastrointestinal and Body/Systemic . Participants rate each symptom on a 5-point ordinal scale, with higher scores indicating a more frequent sign or symptom. For 27 of the items, the scale is as follows: 0 ("Not at all"), 1 ("A little bit"), 2 ("Somewhat"), 3 ("Quite a bit"), and 4 ("Very much"). For 5 items, severity is assessed in terms of numerical frequency, that is (i.e), vomiting or diarrhea (0 times, 1 time, 2 times, 3 times, or 4 or more times); with frequency of sneezing, coughing, and coughed up mucus or phlegm evaluated on a scale from 0 ("Never") to 4 ("Always").The FLU-PRO total score is computed as a mean score across all 32 items comprising the instrument. Total scores can range from 0 (symptom free) to 4 (very severe symptoms).

  8. Time to Improvement of Vital Signs [Up to 28 Days]

    Time to improvement of vital signs was defined as the time from first study treatment to when at least 4 of 5 symptoms (temperature, blood oxygen saturation, heart rate, systolic blood pressure, and respiration rate) had recovered, including normalization of temperature and blood oxygen saturation. Resolution criteria for vital signs: for Temperature: oral temperature less than or equal to (<=) 36.5 degree Celsius (C) for elderly and <=37.2 C for adults; for oxygen saturation: greater than or equal to (>=) 92 percent (%) on room air without supplemental oxygen; for respiratory rate: <= 24 per minutes; for heart rate: <= 100 per minutes and for systolic blood pressure: >= 90 millimeters of mercury (mmHg).

Title Change From Baseline in Influenza Patient-Reported Outcome Questionnaire (FLU-PRO) Total Score
Description FLU-PRO assesses 32 influenza symptoms in each of the following body areas (domains): Nose, Throat, Eyes, Chest/Respiratory, Gastrointestinal and Body/Systemic . Participants rate each symptom on a 5-point ordinal scale, with higher scores indicating a more frequent sign or symptom. For 27 of the items, the scale is as follows: 0 ("Not at all"), 1 ("A little bit"), 2 ("Somewhat"), 3 ("Quite a bit"), and 4 ("Very much"). For 5 items, severity is assessed in terms of numerical frequency, that is (i.e), vomiting or diarrhea (0 times, 1 time, 2 times, 3 times, or 4 or more times); with frequency of sneezing, coughing, and coughed up mucus or phlegm evaluated on a scale from 0 ("Never") to 4 ("Always").The FLU-PRO total score is computed as a mean score across all 32 items comprising the instrument. Total scores can range from 0 (symptom free) to 4 (very severe symptoms).

Outcome Measure Data

Analysis Population Description
FAS was defined as all randomly assigned participants who received at least 1 dose of study drug and who have a confirmed infection with influenza A. Here, N (number of participants analyzed) signifies number of participants evaluable for this OM and 'n' signifies number of participants evaluable at specified time points.
Arm/Group Title Pimodivir 600 mg Plus Oseltamivir 75 mg Placebo Plus Oseltamivir 75 mg
Arm/Group Description Participants received pimodivir 600 milligram (mg) tablets and oseltamivir 75 mg capsules orally twice daily for 7 days. Dose of oseltamivir was adjusted from 75 mg to 30 mg and vice versa during the course of treatment based on the estimated-glomerular filtration rate (eGFR) value. Participants received matching placebo tablets and oseltamivir 75 mg capsules orally twice daily for 7 days. Dose of oseltamivir was adjusted from 75 mg to 30 mg and vice versa during the course of treatment based on the eGFR value.
