Influenza Clinical Trial
Official title:
Multicentre, Randomized, Controlled Clinical Trial Comparing Oseltamivir With Placebo And Zanamivir With Control As The First Line Treatment For Human Swine Influenza (H1N1) Infection In Designated Flu Clinics During The Pandemic Influenza in Hong Kong
To evaluate the efficacy of oseltamivir ,as compared with the placebo arm and zanamivir with its control arm with respect to symptoms duration among patients infected with influenza A (H1N1) virus.
The outbreak of respiratory illnesses in Mexico that began in March 2009 was caused by a
swine origin influenza A (H1N1) virus (S-OIV) that had not been recognized previously in
pigs or humans. As of 17 May 2009, 39 countries have officially reported 8480 cases of
influenza A (H1N1) infection.
The H1N1 influenza A virus appears sensitive to oseltamivir and zanamivir in vitro, but
resistant to amantadine and rimantadine. This study is to test the oseltamivir, zanamivir
and placebo arms as the first line treatment for human swine influenza infection. Through
the study, the investigators may have better understanding about the clinical and,
biochemical, virological profiles of oseltamivir/zanamivir on the H1N1 virus, and optimizing
the treatment strategy among the Chinese population.
