Study Endpoints

Primary Endpoints

Change From Baseline to Week 16 in Sino-Nasal Outcome Test (SNOT) 22 Total Score
Baseline, Week 16

The SNOT-22 is a validated questionnaire to assess the impact of chronic rhinosinusitis (CRS) on quality of life and utilizes a 2-week recall period. It is a 22-item outcome measure on a 5-point category scale applicable to sinonasal conditions and surgical treatments. The total scores range from 0 to 110 with higher total scores implying greater impact of CRS on quality of life.

Proportion of Participants Who Experience Worsening of Asthma by Week 24
up to Week 24

Proportion of participants who experience worsening of asthma by Week 24 as defined by at least 1 of the following: * On 2 consecutive days, morning (AM) peak expiratory flow (PEF) ≤ 75% of mean AM PEF measured over the last 7 days of the Run-in * Forced expiratory volume in 1 second (FEV1) \< 80% of baseline * Increase in rescue medication use of ≥ 6 puffs/day on 2 consecutive days compared to mean use over the last 7 days of the Run-in * Increase in Asthma Control Questionnaire 5 (ACQ-5; see Outcome Measure 2 for description) score of ≥ 0.5 compared to baseline * The occurrence of a severe asthma exacerbation (asthma attack) defined as deterioration of asthma that leads to the use of systemic corticosteroids for at least 3 days, hospitalization, or an Emergency Department visit.
