There are 86 planned AeroTrial locations across five countries: the United States, the United Kingdom, Poland, Hungary, Germany. These sites will begin recruitment in Fall 2008 and continue through Fall 2009.

A listing of active sites and numbers is provided below if you wish to contact a site for more information. If you have asthma and are interested in participating in the study, please take a brief questionnaire to see if you may be a candidate. If you qualify, at the end of the questionnaire you may give us your contact information so we may keep you posted about sites near you. Also, if there is not presently a site near you and we determine a great deal of interest in an underserved area, we will consider opening a site near you.
