| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change From Baseline in Endoscopic Total Nasal Polyp Score (NPS) at Week 56 | Baseline to Week 56 | The total nasal polyp score (NPS) is the sum of the right and left nostril scores (maximum of 8), as evaluated by nasal endoscopy. Higher scores indicate greater symptom severity. The left and right score will be based on a central read with a scale from 0 to 4. Each nasal endoscopy is evaluated by two independent physician reviewers. |
| Primary | Change From Baseline in Mean Nasal Blockage Score (NBS) at Week 56. | Baseline to week 56 | The NBS is an item in the NPSD. Patients were asked to rate the severity of their worst nasal blockage over the past 24 hours using the following response options: 0 - none; 1 - mild; 2 - moderate; 3 - severe. Higher scores indicate greater symptom severity. The NBS and the changes from baseline were summarised every two weeks (bi-weekly). Baseline was the average of daily responses from Day -13 to Day 1. Bi-weekly mean were calculated if at least 8 days in each 14-day period had evaluable data; otherwise, the biweekly mean was set to missing. |
| Secondary | Change From Baseline in Difficulty With Sense of Smell (DSS) Score at Week 56. | Baseline to Week 56 | The DSS is an item in the NPSD. Patients were asked to rate the severity of their worst difficulty with sense of smell over the past 24 hours using the following response options: 0-none; 1-mild; 2-moderate; 3-severe. Higher scores indicate greater symptom severity. The DSS and the changes from baseline were summarised every two weeks (bi-weekly). Baseline was the average of daily responses from Day -13 to Day 1. Bi-weekly mean of DSS was calculated if at least 8 days in each 14-day period have evaluable data; otherwise the bi-weekly mean was set to missing. |
| Secondary | Sinus Opacification by CT Scan at Week 56. | Baseline to Week 56 | Change from baseline in Lund- Mackay score (LMS). The Lund-Mackay score scoring system is used to provide a quantitative assessment of nasal sinuses on sinus CT scans. Based on the sinus CT images, the five sinuses (maxillary, anterior ethmoid, posterior ethmoid, sphenoid and frontal) on each site are score by central radiologist as follows: (0-Normal; 1-Partial Opacification; 2-Total Opacification). The osteomeatal complex is scored for right and left sides (0 - Not occluded; 2- Occluded). The total score ranges from 0 to 24 (higher scores indicate poorer outcomes). |
| Secondary | Disease Specific Health-related Quality of Life (HRQoL): Change From Baseline in SinoNasal Outcome Test (SNOT-22) Score at Week 56. | Baseline to Week 56 | SinoNasal Outcome Test 22 scores are participant-reported and assess physical problems, functional limitations and emotional consequences of SinoNasal conditions. Patient-reported symptom severity and symptom impact over the past 2 weeks are captured via a 6-point scale (0-No Problem to 5-Problem as bad as it can be). The total score is the sum of item scores and has a range from 0 to 110 (higher scores indicate poorer outcomes). |
| Secondary | Time to First Nasal Polyp Surgery | Baseline to Week 56 | Time to the first surgery for CRSwNP= Start date of the first surgery for CRSwNP - date of randomisation + 1 |
| Secondary | Time to First SCS Course for CRSwNP | Baseline to Week 56 | Time to the first SCS use for CRSwNP = Start date of the first SCS use for CRSwNP - date of randomisation + 1 |
| Secondary | Time to First NP Surgery and/or SCS Use for CRSwNP | Baseline to Week 56 | Time to first surgery and/or SCS use for CRSwNP = earlier date of (start date of first surgery for CRSwNP, start date of first SCS use for CRSwNP) - date of randomisation + 1 |
| Secondary | Change From Baseline in Bi-weekly Mean Nasal Polyps Symptom Diary Total Symptom Score at Week 56. | Baseline to Week 56 | The participant completed the nasal polyposis symptom diary each morning throughout the study. The participant was asked to consider their experience with nasal polyposis/nasal polyps over the past 24 hours when responding to each question. Participants were asked to report their experience with nasal polyposis symptoms (nasal blockage, nasal congestion, runny nose, postnasal drip (mucus drainage down the throat), headache, facial pain, facial pressure, difficulty with sense of smell). Participants reported the severity of each symptom and symptom impact at its worst using a 4-point verbal rating scale (0-None to 3-Severe). A total symptom score (range from 0 to 24) was calculated by taking the sum of the 8 equally weighted symptom items. Higher scores indicate greater symptom severity. |
| Secondary | Percentage of Participants With Surgery and/or Use SCS for CRSwNP | Baseline to Week 56 | Nasal polyps surgery is defined as any procedure involving instruments resulting in incision and removal of tissue (e.g. polypectomy, endoscopic sinus surgery). An SCS course can be considered as a new course if the start date is preceded by at least 7 days after the end date of the last SCS course for CRSwNP (i.e. start date of the new course - end date of the last course \> 7) |
