RV568 - Viral Challenge With RSV

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01230645
Recruitment Status : Completed
First Posted : October 29, 2010

Brief Summary:
RV568 is being developed for the treatment of diseases such as asthma, COPD and allergic rhinitis (e.g. hayfever). The main aim of this study is to investigate whether RV568 is effective in reducing the inflammation caused by viral infections such as RSV (respiratory syncytial virus).
