- Greater than or equal to (>=) 18 years of age at initiation of mepolizumab.
- Participants with an investigator’s main diagnosis of CRSwNP confirmed by clinical criteria (including any imaging if performed) where CRSwNP is the main diagnosis indicated for use of mepolizumab per local labelling requirements.
- Participation in an interventional study that includes treatment with an investigational drug and/or treatment for CRSwNP at the same time as the index date (mepolizumab initiation)
- Prior participation in an interventional study that includes treatment with mepolizumab.
- Greater than or equal to (>=) 18 years of age at initiation of mepolizumab.
- Participants with an investigator’s main diagnosis of CRSwNP confirmed by clinical criteria (including any imaging if performed) where CRSwNP is the main diagnosis indicated for use of mepolizumab per local labelling requirements.
- Participants who have already initiated mepolizumab for treatment of CRSwNP more than 12 months prior to study enrolment and have a SNOT-22 score collected ≤30 days prior to mepolizumab initiation and 12 months (+/- 2 weeks) post-initiation (Retrospective Cohort).
- Participants who have already initiated mepolizumab for treatment of CRSwNP fewer than two months prior to study enrolment and have a SNOT-22 score collected ≤30 days prior to mepolizumab initiation (Partially Retrospective Cohort).
- Physician’s decision to prescribe mepolizumab for treatment of CRSwNP; Participant treatment-naïve at time of study enrolment (Prospective Cohort).
- Participant must be willing and able to provide voluntary informed consent (Prospective and partially retrospective cohort).
- Participants must be able to understand and complete study-related questionnaires. Participants must have access to a compatible device and internet access for electronic Participant-reported outcome (ePRO) completion and be willing and able to comply with ePRO data collection (Prospective and partially retrospective cohort).
- Participation in an interventional study that includes treatment with an investigational drug and/or treatment for CRSwNP at the same time as the index date (mepolizumab initiation)
- Prior participation in an interventional study that includes treatment with mepolizumab.
- Diagnosis of eosinophilic granulomatosis with polyangiitis, hyper-eosinophilic syndrome, cystic fibrosis, immunodeficiency, and primary ciliary dyskinesia, or any other condition that would make it difficult for the participant to fulfil the study criteria, per the investigator’s discretion.
- Prior use of another respiratory biologic (including but not limited to omalizumab, reslizumab, dupilumab, tezepelumab, or benralizumab) within six months of mepolizumab index date.
- Use of concomitant therapy with another respiratory biologic at the time of mepolizumab treatment.
- Three or more functional endoscopic sinus surgery (FESS) which includes anterior maxillectomy and/or ethmoidectomy and/or sphenoidotomy or 3 or more Endoscopic sinus surgery (ESS) with or without DRAF Iib or DRAF III.
- Pregnant or breastfeeding at the mepolizumab initiation (note: Participants who become pregnant during the study will not be excluded, provided they consent to continue with mepolizumab).
