Outcome Measures
Primary Outcomes (1)
Change From Baseline (CFBL) in the 7-day Average Composite Score of 3 Cardinal Symptoms (3CS) in Participants Without Nasal Polyps
The 3CS are nasal blockage/obstruction/congestion, anterior/posterior nasal discharge, and facial pain/pressure. The diary is completed daily by study participants throughout the study. Each symptom is rated on a 4-point (0-3) scale where 0= none/absent symptoms, 1=mild symptoms, 2=moderate symptoms, and 3=severe symptoms. The composite score of 3CS is the sum of the three cardinal symptom scores. The 3CS total score ranges from 0-9, with higher scores indicating worse symptoms.
