Study Endpoints

Primary Endpoints

Mean Change From Baseline in the Daily Major Symptom Score (MSS) Over the Entire Treatment Period, Full Analysis Set
Baseline (Day 1), Day 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15

The MSS combines the 5 most relevant symptoms of rhinosinusitis based on expert clinician recommendations (rhinorrhea/ anterior discharge, postnasal drip, nasal congestion, headache, and facial pain/pressure). The patient rated the severity of each of the five symptoms of the MSS using a four-point rating scale of increasing severity (0 = none/not present, 1 = mild, 2 = moderate, 3 = severe). The MSS is then the sum of single ratings with a possible range from 0 to 15. Mean change from baseline in the daily Major Symptom Score (MSS) over the entire treatment period was calculated as the average total score from Day 2 to 15 compared to Baseline (Day 1). Negative change from baseline means improvement.

Mean Change From Baseline in the Daily Major Symptom Score (MSS) Over the Entire Treatment Period, Per-Protocol Set
Baseline (Day 1), Day 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15
