A Study of Intravenously Administered Tamiflu (Oseltamivir) in Patients Over 13 Years of Age With Influenza

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.

Nasal and throat swabs were collected on Days 1, 4, 6, 11, 15, and 30 and were sent to a central laboratory for analysis. The presence of viral shedding was determined by a positive culture [log10 median tissue culture infective dose (TCID50) > 0.5) or detection by RT-PCR (log 10 copies/mL).

Nasal and throat swabs were collected on Days 1, 4, 6, 11, 15, and 30 and were sent to a central laboratory for analysis. The presence of viral shedding was determined by a positive culture=log10 median tissue culture infective dose (TCID50) > 0.5.

Nasal and throat swabs were collected on Days 1, 4, 6, 11, 15, and 30 and were sent to a central laboratory for analysis. The presence of viral shedding was determined by detection by RT-PCR (log 10 copies/mL).

Nasal and throat swabs collected at Baseline and Day 4 were sent to a laboratory for analysis. Viral influenza titer (amount of virus present) was determined by culture. A log 10 median tissue culture infective dose (TCID50) > 0.5= Positive culture. A negative change from Baseline indicated improvement (less virus present).

Nasal and throat swabs were collected at Baseline and Day 4 and were sent to a central laboratory for analysis. Influenza Viral titers (amount of virus present) were determined by RT-PCR for Flu A and Flu B and were reported in log 10 copies/milliliter (mL). A negative change from Baseline indicated improvement (less virus present).

Fever was defined as a temperature of ≥ 37.8 C (degrees Celcius).

Fever was defined as a temperature of ≥ 37.8 C (degrees Celsius). Resolution of fever was a temperature ≤ 37.2 for at least 21.5 hours.

Nasal and Throat swabs were collected on Days 1, 4, 6, 11, 15 and 30 and were sent to a central laboratory for testing. Viral resistance was determined by phenotypic and genotypic testing.

Influenza (flu) symptoms were nasal congestion, sore throat, cough, aches and pains, fatigue, headache or chills.
