About this study
Official title: The Effect of Anti-IL17 on Airway Hyperresponsiveness and Resistance: a Longitudinal Cohort Study
This observational longitudinal cohort study aims to assess the effect of monoclonal antibodies targeting interleukin 17 (anti-IL-17) on airway hyperreactivity and airway resistance. The study involves adult participants suffering from dermatological or rheumatological illness, who are planning to start treatment with monoclonal antibodies targeting interleukin 17 as a part of the treatment of these diseases.
The primary outcome of this study will be changes in airway hyperresponsiveness to methacholine challenge reported as response-dose-ratio before and after initiation of anti-IL17 treatment regardless of presence of respiratory disease. Furthermore, the potential effect of anti-IL-17 on airway resistance will be assessed using conventional spirometry for measuring changes in FEV1 and Airwave oscillometry.
A reduced degree of airway hyperreactivity and airway resistance after initiating ani-IL-17 could indicate effectiveness of anti-IL-17 in asthma patients which would have to be examined further in a population of asthma patients.
Read the detailed description
Background:
Antibodies towards interleukin 17 (IL-17) are approved for treating various rheumatological and dermatological diseases like psoriatic arthritis, ankylosing spondylitis and plaque psoriasis. In recent years, IL-17 has been suggested as a potential driver of severe non-Type 2 asthma because of its' association with glucocorticoid resistance and symptoms of severe asthma. Since conventional treatment is often less effective in patients suffering from non-Type 2 asthma, sometimes adequate disease control cannot be achieved, thus limiting these patients' opportunity for physical exercise, and thereby increasing the risk of obesity and heart disease. Furthermore, obesity has been shown to increase asthma symptoms and frequency of exacerbations.
IL-17 has shown to be upregulated by female sex hormones which may explain the sex specific traits of severe non-Type 2 asthma. In obese mice, IL-17 has shown to be directly responsible for the induction of airway hyperresponsiveness (AHR), thus making it a potential target for treatment. It is especially of interest that none of the previously performed human studies have investigated the effect of blocking IL-17 on AHR. A previous study investigating the effect of blocking IL-17 on lung function, measured as change in FEV1 (forced expiratory volume in 1 second) in moderate to severe patients with asthma, did not find any significant effect. However, this study included both men and women as well as lean and obese participants which could explain the lack of clinical difference. Another previous study also showed no effect of anti-IL17 in general. However, this study showed that those with the greatest reversibility to bronchodilators had the best improvement in symptoms. Although negative, these studies brought us further by showing that anti-IL-17 treatment was safe and tolerable for patients with moderate to severe asthma. Oscillometry has been known for several decades but is only on its' way into clinical practice. Oscillometry is more sensitive than spirometry in detecting small airway disease and AHR. Thus, using oscillometry in studies investigating airway resistance in asthmatic individuals in addition to spirometry, is warranted.
Objectives The overall objective of this study is to determine whether AHR and airway resistance is reduced when initiating treatment with anti-IL17 antibodies for other indications than pulmonary disease. Changes in AHR to methacholine challenge will be reported as response-dose-ratio before and after initiation of anti-IL17. Airway resistance will be assessed using both conventional spirometry for measuring changes in FEV1 and Airwave oscillometry.
Hypothesis
Primary hypothesis: In rheumatologic and dermatological patients commencing anti-IL-17 for other reasons than pulmonary disease, we expect a reduction in airway responsiveness to methacholine challenge after 2-4 months of treatment when compared to prior to initiation of anti-IL-17 treatment.
Secondary hypotheses: Anti-IL17 treatment will show no effect on FEV1, measured using conventional spirometry but will improve measures of airwave oscillometry.

This observational longitudinal cohort study aims to assess the effect of monoclonal antibodies targeting interleukin 17 (anti-IL-17) on airway hyperreactivity and airway resistance. The study involves adult participants suffering from dermatological or rheumatological illness, who are planning to start treatment with monoclonal antibodies targeting interleukin 17 as a part of the treatment of these diseases.
The primary outcome of this study will be changes in airway hyperresponsiveness to methacholine challenge reported as response-dose-ratio before and after initiation of anti-IL17 treatment regardless of presence of respiratory disease. Furthermore, the potential effect of anti-IL-17 on airway resistance will be assessed using conventional spirometry for measuring changes in FEV1 and Airwave oscillometry.
A reduced degree of airway hyperreactivity and airway resistance after initiating ani-IL-17 could indicate effectiveness of anti-IL-17 in asthma patients which would have to be examined further in a population of asthma patients.

Questions about this trial
What is this clinical trial studying?
An observational study of Asthma, run by Copenhagen University Hospital, Hvidovre 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 1 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: looking for participants now, as of the sponsor's last update on 18 Mar 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.
