Safety was evaluated through assessment of Adverse Events (AEs).
Safety evaluation included assessment of Adverse Events (AEs).
The time-weighted change from baseline in log10 tissue culture infective dose50 (TCID50/mL) was calculated on a by-subject basis through 48 hours using the trapezoidal rule with all available data minus the baseline value. Ninety-five percent confidence intervals about the median time-weighted change from baseline were presented for each treatment group.
5-10 days
The primary efficacy endpoint was the time to alleviation of symptoms calculated as the number of hours from initiation of study drug until the start of the time period in which all 7 symptoms of influenza were either absent or present at a level no greater than mild for at least 21.5 (24 hours - 10%) hours. Subjects with missing diary data were excluded and those who did not experience alleviation of symptoms were censored at the last observed symptom assessment.
Time to clinical stability was summarized overall and for individual clinical signs for each treatment group using the method of Kaplan Meier. Subjects who did not experience clinical stability were censored at the date of their last non-missing assessment during the study (whether this assessment occurred as an inpatient or as an outpatient).
