Inclusion criteria
Inclusion criteria: 1.Signed informed consent form prior to trial participation, demonstrating full understanding of trial objectives, procedures, and potential adverse reactions. 2.Age between 18 and 75 years (inclusive) at the time of informed consent signing, regardless of gender. 3.Diagnosis of bilateral chronic rhinosinusitis with nasal polyps (CRSwNP) meeting the diagnostic criteria of the "Chinese Guidelines for the Diagnosis and Treatment of Chronic Rhinosinusitis (2018)"; 4.At least one prior course of systemic corticosteroids (prednisone 0.5-1 mg/kg/day or 15-30 mg/day or equivalent for minimum 5 days) within 2 years before screening, with persistent bilateral CRSwNP; AND/OR contraindication/intolerance to systemic corticosteroids; AND/OR prior nasal polyp surgery performed more than 6 months before screening. 5.Bilateral Nasal Polyp Score (NPS) >= 5 (maximum score 8) with >= 2 points per nostril, as assessed by nasal endoscopy during screening and randomization. 6.Nasal Congestion Score (NCS) >= 2 at screening (daily average) and randomization (weekly average). 7.Persistent symptoms of rhinorrhea and/or hyposmia/anosmia for over 8 weeks prior to screening. 8.22-item Sino-Nasal Outcome Test (SNOT-22) score >= 30 at screening and randomization. 9.Stable dose of intranasal corticosteroids (INCS) for >4 weeks prior to screening (subjects using non-mometasone furoate nasal spray [MFNS] products must agree to switch to MFNS during the study). 10.Documented asthma evidence meeting either criterion: >= 12% and >= 200mL absolute improvement in FEV1 and/or FVC reversibility within 12 months before Visit 1, or >= 12% and >= 200mL absolute improvement post-bronchodilator (albuterol 4 puffs) during screening (15-30 minutes post-dose). 11.For asthmatic subjects: stable symptoms for >= 4 weeks pre-screening (if medicated, inhaled corticosteroid doses must be stable for >= 4 weeks at 70% for MFNS and daily symptom diary completion >70% (missing diary days count as non-compliance). 13.Agreement to practice effective non-pharmacologic contraception from informed consent until 6 months post-final dose, for subjects/partners of childbearing potential.
