Full description
The study consists of a Screening Period (up to 4 weeks), Treatment Period (24 weeks for double-blind treatment period and 28 weeks for open-label maintenance treatment) and Safety Follow-up Period (8 weeks).
180 patients who meet eligibility criteria will be randomized 1:1 to receive either CM310 300 mg or matched placebo subcutaneously every two weeks (Q2W) for a total of 12 times at the double-blind treatment period and 14 times at the open-label treatment period. All patients will receive MFNS on a daily basis as a background treatment throughout the study.
Central reading will be implemented to nasal endoscopic nasal polyp score (NPS) , CT scans to Lund-Mackay score and volume of the involved area of nasosinusitis on 3D-construction images, and nasal polyp biopsy tissue analysis to eosinophil counts & percentage.
