Trial overview
Official title: REALITI-N: A Multinational, Observational Study to Evaluate the Real-World Effectiveness of Mepolizumab in Participants with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP)
Trial description: This is a multinational study which has both retrospective and prospective phases to study effectiveness and improvements in Health-related Quality of Life (HRQoL) among adult participants with a confirmed diagnosis of Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) over 12 months of mepolizumab use in a real-world setting. There will be three participant cohorts in this study which are: - Participants who are newly prescribed to mepolizumab (i.e., participants have not yet initiated mepolizumab prior to enrolment) for treatment of CRSwNP (prospective cohort); - Participants who have already initiated mepolizumab for treatment of CRSwNP more than 12 months prior to study enrolment, and have a Sino-Nasal Outcome Test (SNOT-22) score collected less than or equal to (=<) 30 days prior to and 12 months (+/-2 weeks) post-initiation of mepolizumab (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). The primary purpose of the study is to evaluate the mean change in the SNOT-22 total score from baseline to 12 months whilst being treated with mepolizumab.

No
- 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.

- Prior participation in an interventional study that includes treatment with mepolizumab.
Inclusion and exclusion criteria
Inclusion criteria:
- 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).
