Trial summary
The objective of the study is to collect real-life data worldwide, which already have been collected in national databases, to merge the data and the knowledge with the focus of better care for the individual patients, more efficient use of the hospital cost of biologics and working for "personalized medicine".

About this study
Official title: InternatioNal seVerE CRSwNP Registry (INVENT) 2024-2028
The objective of the study is to collect real-life data worldwide, which already have been collected in national databases, to merge the data and the knowledge with the focus of better care for the individual patients, more efficient use of the hospital cost of biologics and working for "personalized medicine".
Read the detailed description
Regional or national registries have evaluated the efficacy of different biologics in severe uncontrolled CRSwNP coordinated by several academic centres in Europe. At present, these registries have not been merged nor allowed the comparison in real-life efficacy between the 3 different monoclonal antibodies (mepolizumab, dupilumab, omalizumab) with different mechanism which has been approved for the indication of CRSwNP and the effect of the nasal polyp score. Some countries have allowance for some of the different biologic drugs, other countries have other combination of the drugs. Despite the heterogeneity in availability of biologics for the indication of CRSwNP, the merge of data might lead to very interesting outcomes.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in The Sino-Nasal Outcome Test 22 (SNOTT22) score
The success rate indicated by a significant change in health-related quality of life related to nasal symptoms measured with the questionnaire SNOT22.
Measured: 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, and 60 months follow up
Change in Nasal Polyp Score (NPS)
The NPS scale ranges from 0 (no polyp) to 4 (large polyps) for each nostril. The total score ranging from 0-8.
Measured: 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, and 60 months follow up
Change in visual analogue scale (VAS)
Change in VAS related to nasal symptoms. Minimum score = 0 and maximum score = 10. High score indicates worse nasal symptoms
Measured: 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, and 60 months follow up
Change in olfactory function
Change in olfactory function measured with Sniffin' Stick 16 blue. Minimum score = 0. Maximum score = 16. A score between 0-8 indicates anosmia, a score between 8-11 indicates hyposmia, and a score >11 indicates normosmia.
Measured: 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, and 60 months follow up

Questions about this trial
What is this clinical trial studying?
An observational study of Chronic Rhinosinusitis With Nasal Polyps (CRSwNP), run by Vibeke Backer at 1 site in Denmark.
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 3 inclusion and 3 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: under way, not looking for participants, as of the sponsor's last update on 8 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. 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.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in The Sino-Nasal Outcome Test 22 (SNOTT22) score (time frame: 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, and 60 months follow up). The study lists 4 primary outcomes in all. 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 8 Apr 2025; AzTrials last refreshed its copy on 6 Nov 2026.
