- Primary Outcome Measures
Name Time Method Main Objective: To evaluate prospectively the safety and tolerability of oseltamivir for the treatment of influenza in immunocompromized patients and characterize the effects of oseltamivir in immunocompromized patients on the development of resistant influenza virus;Secondary Objective: - Pharmacokinetics of oseltamivir carboxylate (e.g., clearance, volume of distribution) in immunocompromised patients with confirmed influenza infection<br>- Virologic course of influenza<br>- Time to resolution of influenza symptoms<br>- Clinical course of influenza;Primary end point(s): The primary endpoints are safety and development of resistance ;Timepoint(s) of evaluation of this end point: Time points up to day 40
- Secondary Outcome Measures
Name Time Method Secondary end point(s): 1. Time to alleviation of all clinical influenza symptoms<br>2. Proportion of viral shedding<br>3. Viral load<br>4. Development of secondary illnesses<br>5. Pharmacokinetics: Area under the concentration-time curve (AUC);Timepoint(s) of evaluation of this end point: 1.- 4.: Time points up to day 40<br>5.: Samples for PK analysis will be collected at Day 6
