 Seven hundred fifty patients with histories of seasonal allergies will be screened in late summer and early fall at 25 sites across the U.S. Approximately 375 patients, based on severity of symptoms will be randomized among the treatments 150 to R926112, 150 to placebo, 75 to Beconase. During, and for about 2-3 weeks prior to the study, patients will have to abstain from other anti-allergy medications. Patients will fill out diary cards two times per day to record their symptoms. The entire study should take between 2-4 weeks.
