Primary outcomes
- Mean Change From Baseline Over the Entire Treatment Period in the Daily Reflective Nasal Congestion Score — Baseline, Day 7
The reflective nasal congestion score was captured in participant diaries just before the 8:00 a.m. dose and 12 hours later just before the 8:00 p.m. dose. Participants rated congestion on a 4-point scale of severity from 0 (best) to 3 (worst), with 0 = absent symptoms, 1 = mild symptoms, 2 = moderate symptoms, and 3 = severe symptoms. The daily reflective nasal congestion symptom score was defined as the average of the morning and evening reflective nasal congestion score for the entire treatment period. Baseline was defined as the average of the daily scores over the 4 consecutive 24-hour periods before randomization.
