- Patients have been informed and signed consent to participate in the study.
- For those patients not suitable for surgery, the criteria of the EUFOREA guidelines for indication of biological treatment will be used (4 criteria, one of them being ≥300 cells/μL BEC).

About this study
This randomized, controlled multicenter trial will recruit patients aged 18 to 70 7 years with recurrent nasal polyposis requiring surgery and indication for biologic treatment according to EPOS 2020 guideline. Patients in the Mepolizumab arms will receive 100 mg of subcutaneous mepolizumab every 4 weeks for a total of 12 doses in addition to daily topical corticosteroid treatment.
All study procedures will be performed in five study visits and may take approximately 30 minutes. Clinical assessments include different questionnaires and nasal endoscopy. This trial includes three treatment arms.

- Combined group (In-office nasal polypectomy group with mepolizumab): This group will undergone in-office nasal polypectomy and will receive Mepolizumab.
- Medical group (mepolizumab): This group will receive Mepolizumab.
- Surgical group (In-office nasal polypectomy): This group will undergone in-office nasal polypectomy. The main advantage is that it allows comparison of mepolizumab versus surgery and surgery/mepolizumab versus surgery + mepolizumab, providing more information on the most effective therapeutic approach.
The presence of adverse effects will be assessed in each treatment arm.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Mepolizumab and Polypeptomy in people with Rhinosinusitis Chronic and Polyp, Nasal, run by Instituto de Investigación Marqués de Valdecilla at 7 sites in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 28 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mepolizumab+polypectomy compared to mepolizumab or polypectomy, using the change from baseline in sinonasal outcome test (SNOT-22) total score (time frame: up to 52 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jun 2023; AzTrials last refreshed its copy on 8 Nov 2026.
