Trial summary

Approximately 5-10% of people with asthma do not respond to to standard therapy and are referred to as having difficult asthma. Evidence shows that this poor response is not always related to asthma severity and non-adherence to treatment is recognized as a common underlying problem, in 35% of these patients.

About this study

Approximately 5-10% of people with asthma do not respond to to standard therapy and are referred to as having difficult asthma. Evidence shows that this poor response is not always related to asthma severity and non-adherence to treatment is recognized as a common underlying problem, in 35% of these patients. Recognising non-adherence in the clinic is problematic as there is no straightforward objective test to identify it.

Previous studies have demonstrated up-regulation of FKBP51 gene expression following treatment with steroids, making it a potential biomarker of steroid exposure. It is therefore also a potential biomarker of non-adherence to inhaled corticosteroid therapy. The investigators plan to assess the feasibility of distinguishing non-adherent subjects who are by omission steroid naïve from adherent subjects, steroid exposed subjects using FKBP51 gene expression in sputum and throat swabs.

To do this the investigators will obtain throat swab and sputum samples from healthy volunteers, steroid naïve asthmatics and adherent asthmatics on high dose ICS to assess if FKBP51 gene expression is comparable in each group.

The investigators will then compare the FKBP51 gene expression response to directly observed inhaled steroid therapy in steroid naïve, non-adherent and adherent asthmatics. This will identify if the response in gene expression distinguishes steroid exposed (adherent) from steroid naïve (non-adherent) patients.

Identifying non-adherence will benefit patients by enabling appropriate tailored management for non-adherence to enhance treatment effectiveness. It will also identify patients with therapy resistant asthma who have an unmet need and may benefit from expensive novel therapies such as Omalizumab.

Questions about this trial

What is this clinical trial studying?

A study testing inhaled steroid in people with Asthma, run by Liam Heaney at 1 site in United Kingdom.

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 21 inclusion and 17 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: finished, as of the sponsor's last update on 10 Oct 2014. 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 United Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 FKBP51 gene expression (time frame: 7 days). 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 10 Oct 2014.
