PRIMARY outcome

Timeframe: Baseline and 8 weeks

Population: All subjects enrolled with SNOT-22 measurements at both baseline and 8 weeks were included. Three enrolled subjects treated with ifetroban did not have SNOT-22 measurements for both timepoints and therefore were not analyzed for this outcome.

Sinonasal Outcome Test-22 (SNOT-22) score is a scale with a minimum score of 0 and a maximum score of 110 based on the presence and severity of symptoms and outcomes of rhinosinusitis. Higher scores indicate worse symptoms and/or outcomes.

SECONDARY outcome

Timeframe: Baseline and 8 weeks

Population: All subjects enrolled with Asthma Control Questionnaire-7 measurements at both baseline and 8 weeks were included. Ten enrolled subjects treated with ifetroban and 5 enrolled subjects treated with placebo did not have Asthma Control Questionnaire-7 measurements for both timepoints and therefore were not analyzed for this outcome.

The Asthma Control Questionnaire-7 is a scoring system with a minimum score of 0 and a maximum score of 6 based on the severity and frequency of asthma symptoms. Higher scores indicate worse control of asthma symptoms.

Population: All subjects enrolled with Total Nasal Symptom Score (morning) measurements at both baseline and 8 weeks were included. Five enrolled subjects treated with ifetroban and 9 enrolled subjects treated with placebo did not have Total Nasal Symptom Score (morning) measurements for both timepoints and therefore were not analyzed for this outcome.

The Total Nasal Symptom Score is a scoring system with a minimum score of 0 and maximum score of 15 based on severity of nasal symptoms. Higher scores indicate worse nasal symptoms.
