Participant Flow

This 2 week ocular allergy study was conducted at 2 ophthalmology clinics in the United States. The first participant was enrolled on 4/22/2010 and the last participant visit was 5/30/2010.

238 participants were screened, a total of 101 participants with seasonal and perennial allergy were randomized into the study. These 101 participants comprised the safety population, 90 of which completed the study. The ITT population was comprised of 97 subjects (4 excluded due to no post CAC-assessment).
