Assessment
Primary outcomes
Sensitivity of influenza viruses
A neuraminidase activity assay is performed to quantitatively assess sensitivity to oseltamivir (as expressed by IC50) using the isolated viral neuraminidase of isolated and identified influenza viruses. If sensitivity (as expressed by IC50) is reduced (increased IC50), the neuraminidase and hemagglutinin genes of the isolated virus are analyzed.
- Sensitivity by influenza virus type.
- Rate of influenza virus resistance and its 95% confidence interval.
- Variation in sensitivity will be considered.
- Variation in neuraminidase and hemagglutinin amino acids will be considered.
Key secondary outcomes
(1)Efficacy
(1-1)Duration of pyrexia:to
For patients with body temperature over 37.8 immediately before taking Tamiflu, the period from the time when Tamiflu treatment started to the time when body temperature
Decreased to under 36.9 (in chidren, under 37.4).
However, when comparing to data from the development phase, patients with body temperature over 38.0 immediately before taking Tamiflu will be considered.
(1-2)Duration of symptoms:
For patients in whom influenza symptoms were classified as Moderate or Severe immediately before taking Tamiflu, the period from the time when Tamiflu treatment started to the time when all influenza symptoms became Absent or Mild.
(2)Safety
Incidences of adverse events and adverse drug reactions (by SOC and symptom).
