An Influenza Resistance Information Study (IRIS)

This study is currently recruiting participants. (see Contacts and Locations)
Verified March 2015 by Hoffmann-La Roche
Sponsor:
Information provided by (Responsible Party):
Hoffmann-La Roche
ClinicalTrials.gov Identifier:
NCT00884117
First received: April 15, 2009
Last updated: March 2, 2015
Last verified: March 2015
  Purpose

This study will assist in the early detection of influenza resistant to antivirals, and will monitor the clinical outcome of patients infected with influenza according to subtype and susceptibility. Patients clinically diagnosed with influenza will undergo a rapid diagnostic test, and viral sampling at baseline and on days 3 and 6. Patients will be clinically managed according to local guidelines (no treatment, or treatment with neuraminidase inhibitors or other appropriate therapies).
