Biologic initiation or switching does not trigger this additional 2-week visit.\n\nCollected information will include demographic and clinical characteristics, medical and surgical history, comorbidities, treatment patterns, symptom scores, disease-related quality of life, nasal polyp assessments, treatment outcomes, treatment escalation events, health care resource use, economic and humanistic burden, and safety events. Laboratory results and biological specimens, including blood, nasal polyp tissue, nasal cells, and nasal secretions, may be collected as specified in the protocol and when applicable.\n\nThe primary assessments describe changes from baseline in the Total Nasal Symptom Score and the 22-item Sino-Nasal Outcome Test, and the proportions of participants classified as cured, controlled, or uncontrolled at months 12, 24, and 36.
