简要总结
This study will evaluate the effect and safety of 611 in patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP)
详细描述
The main purpose is to evaluate the effect of 611 on a background of mometasone furoate nasal spray (MFNS) in reducing endoscopic nasal polyp score (NPS) and nasal congestion/obstruction score (NCS) severity in eligible patients with CRSwNP whose disease remains inadequately controlled despite daily treatment with intranasal corticosteroid (INCS) therapy in comparison to placebo

结局指标
主要结局
Change From Baseline at Week 24 in Bilateral Nasal Polyp Score (NPS)
时间窗: 24 weeks
NPS is evaluated by nasal endoscopy. For each nostril, NPS is graded based on polyp size from 0 = no polyps to 4 = large polyps causing complete obstruction of inferior nasal cavity; lower score = smaller sized polyps. Bilateral NPS is the sum of right and left nostril scores, ranges from 0 (no polyps) to 8 (large polyps), higher score = more severe disease
Change From Baseline at Week 24 in Nasal Congestion Symptom Severity Score (NCS)
时间窗: 24 weeks
NCS is assessed by the participants daily from visit 1 and throughout the study on a scale of 0 to 3, where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms and 3 = severe symptoms, with higher scores indicates more severity.
次要结局
- Change From Baseline to the End of study in Lund Mackay Score(through study completion, an average of 13 months)
- Change From Baseline to the End of study in Total Nasal Symptom Score (TNSS)(through study completion, an average of 13 months)
- Change From Baseline to the End of study in the University of Pennsylvania Smell Identification Test (UPSIT) Score(through study completion, an average of 13 months)
- Change From Baseline to the End of study in 22-item Sino-nasal Outcome Test (SNOT-22) Scores(through study completion, an average of 13 months)
- Adverse events (AEs), measurement of vital signs，physical examination，electrocardiogram and laboratory tests at each visit.(through study completion, an average of 13 months)
- 611 Concentration in Serum(through study completion, an average of 13 months)
