Study summary

The investigators aim to investigate two major so far unresolved topics in CRSwNP research: (1) Thorough functional and molecular characterisation of barrier function in patients suffering from CRSsNP and CRSwNP and (2) effect of dupilumab treatment on barrier function in polyp patients. This will be achieved in patient-derived samples by employing measurement of barrier function in primary cell cultures in combination with a mass cytometry based imaging approach, transcriptomic analysis as well as cytokine and microbiome data of individual patients.

Read the detailed description

Primary objective 1: Characterization of differences in barrier function of the nasal epithelium in patients suffering from CRSsNP, CRSwNP with and without asthma or N-ERD (in absence of therapy with monoclonal antibodies). T Primary objective 2: Effect of dupilumab treatment on barrier function of the nasal epithelium in patients suffering from CRSwNP with and without asthma or N-ERD.

Study population

Patients with chronic rhinosinusitis with and without nasal polyps

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • 18-99 years of age
  • Willingness to participate in the study
  • Suffer from chronic rhinosinusitis defined as in EPOS 2020 criteria, see main text
  • Group 1 (n=20, CRSsNP): Absence of nasal polyps
  • Group 2 (N=60, CRSwNP): Presence of nasal polyps as confirmed by endoscopy or CT and planned therapy with dupilumab
  • Presence or absence of non-steroidal anti-inflammatory drug (NSAID)-Exacerbated Respiratory Disease (N-ERD)
  • Patients with a history of treatment with monoclonal antibodies will only be included if at least a of 6 months has passed

Exclusion criteria

Exclusion Criteria:

  • Pregnancy (as determined by ß-HCG test) or breast feeding
  • Patients with severe anatomic variations or deviations that do not allow access to all areas in the nasal cavity
  • Patients with cystic fibrosis or primary ciliary dyskinesia
  • Patients with permanent
  • A mental condition rendering the subject unable to understand the nature, scope, and possible consequences of the study
  • Patients with comorbidity as determined by the evaluating committee
  • Patients with a history of exacerbation of chronic rhinosinusitis 4 weeks prior to the screening visit
  • Intake of a burst of systemic for the treatment of CRS 4 weeks prior to the screening visit
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 7, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
