Safety was assessed by adverse events (AEs) as measured by the collection of AEs, vital signs, electrocardiograms and laboratory parameters. An AE was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug. Preexisting conditions that worsened during the study were reported as adverse events. A serious adverse event is any experience that suggests a significant hazard, contraindication, side effect or precaution that: results in death, is life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant. On treatment = AEs that started between the day of first dose and within 2 days after the last dose. Off treatment = AEs that started more than 2 days after the last dose of study drug.

Resistant virus included new influenza A virus subtype hemagglutinin type 1 and neuraminidase type 1 (New AH1N1).

An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

Resistance was defined as the presence of oseltamivir resistance mutations in viruses isolated from nasopharyngeal swab samples, identified by sequencing of the neuraminidase (NA) and hemagglutinin (HA) genes (genotypic resistance) and/or determination of the oseltamivir concentration at which the response is reduced by half (IC50) in an NA inhibition assay (phenotypic resistance). Reported are post-baseline phenotypic and genotypic resistance in adults \>/= 18 years and children and adolescents \<18 years in the modified Intent-to-Treat infected (mITTi) population.

The percentage of transplant patients in the safety population who experienced tissue rejection and/or GvHD is reported.

Oseltamivir carboxylate is active metabolite of oseltamivir. AUC0-12 was estimated for oseltamivir and oseltamivir carboxylate by linear trapezoidal rule

Oseltamivir carboxylate is an active metabolite of oseltamivir. Cmax was estimated for both oseltamivir and Oseltamivir carboxylate by non-compartmental analysis.

Plasma samples were obtained up to 90 hours post-dose during the first dose analysis (Days 1 to 5), and the maximum observed concentration was recorded. The Cmax was averaged among all participants and expressed in nanograms per milliliter (ng/mL).

Plasma samples were obtained up to 90 hours post-dose during the second dose analysis (Days 38 to 43), and the maximum observed concentration was recorded. The Cmax was averaged among all participants and expressed in ng/mL.

Plasma samples were obtained up to 90 hours post-dose during the first dose analysis (Days 1 to 5), and the AUC was determined from 0 to 12 hours (AUC12) and up to the last measurable concentration (AUClast). Values were averaged among all participants and expressed in nanograms by hours per milliliter (ng\*h/mL).

Plasma samples were obtained up to 120 hours post-dose during the first dose analysis (Days 1 to 6), and the maximum observed concentration was recorded. The Cmax was averaged among all participants and expressed in ng/mL.

Plasma samples were obtained up to 168 hours post-dose during the second dose analysis (Days 36 to 43), and the maximum observed concentration was recorded. The Cmax was averaged among all participants and expressed in ng/mL.
