    both scored as at least "moderate".
    The time of onset of flu-like symptoms to the time anticipated for the start of
    treatment must be ≤48 hours. Onset of symptoms is defined as the first time (within 1
    hour) the subject becomes aware of respiratory or systemic symptoms compatible with
    the flu or experiences an oral temperature ≥38°C (100.4°F)
    Positive Rapid Influenza Diagnostic Test for influenza type A
    Body mass index (BMI) of 18.0 to 33.0 kg/m2, inclusive, and a total body weight >50

You may not be eligible for this study if the following are true:

  • History of any illness or any clinical condition that, in the opinion of the
    investigator or the subject's general practitioner, might confound the results of the
    tudy or pose an additional risk in administering study drug(s) to the subject.
    Any condition possibly affecting drug absorption (e.g., gastrectomy, cholecystectomy,
    or other gastrointestinal tract surgery, except appendectomy).
    Immunized (intranasal or injected vaccine) against influenza in the 6 months before
    tudy entry.
    At Screening, an ECG that is abnormal and deemed by the investigator(s) to be
    clinically significant.
    For female subjects: Pregnant or nursing subjects and female subjects of childbearing
    potential who are unwilling or unable to use an acceptable method of contraception as
    outlined in this protocol.
    For male subjects, unwilling to comply with contraception requirements as outlined in
    the study protocol.
    Blood donation (of approximately 1 pint [500 mL] or more) within 56 days before the
    first study drug dose.
    Use of the following medications:
    Influenza antiviral medication (oseltamivir, zanamivir, rimantidine, or
    amantadine) within 14 days or ribavirin within 6 months of screening.

    glyburide, irinotecan, repaglinide, rifampin, telmisartan, valsartan, and
    olmesartan, from Day 1 through the last dose of study drug. "Statins" (i.e., HMG
    CoA reductase inhibitors) may be continued, but subjects should be cautioned and
    observed for potential "statin"-related toxicity. Alternatively, subjects can
    abstain from statins for the duration of study drug dosing.
    Strong inhibitors or inducers of CYP3A metabolism, including carbamazepine,
    clarithromycin, HIV and HCV protease inhibitors, itraconazole, ketoconazole,
    nefazodone, phenytoin, posaconazole, rifampin, St. John's wort, telithromycin,
    and voriconazole from 2 weeks prior to the first dose of study drug until the
    last PK sample is collected on Day 8.
    An investigational drug or device 30 days before the first dose of study drug, 5
    half lives before the first dose of study drug, or time determined by local
    requirements, whichever is longest.
