About this study
Official title: Novel Asthma Biomarkers to Predict the Response to Inhaled Corticosteroid
Novel asthma biomarkers to predict the response to inhaled corticosteroid Brief description: This will be a single center study of asthmatic subjects and healthy controls which will investigate mechanisms underlying different response to inhaled corticosteroid, the mainstay of asthma therapy. Only about half of the asthmatic patients have improved lung function after treatment of inhaled corticosteroid. The investigators hypothesize that there are biomarkers such as epithelial cytokines (IL-25, IL-33, TSLP) in airway tissues or plasma of asthmatic patients which could predict the response of asthmatic patients to inhaled corticosteroid. Finding novel asthma biomarker will help the clinicians to choose the optimal treatment for individual asthmatic patient.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
BudesonideDrug
Also called Pulmicort
Inhaled powder of inhaled corticosteroid, 2 puffs (200mcg) twice a day for 8 weeks
| Study group | Role | What they receive |
|---|---|---|
| Healthy controls | No intervention | Healthy controls who will be studied at baseline and serve as a control group for the bronchoscopy, induced sputum and peripheral blood collection. |
| Asthmatics (treatment) | Active comparator | Steroid-naïve asthma, randomized to inhaled budesonide, 2 puffs (200mcg) twice a day for 8 weeks. These subjects will undergo bronchoscopy and induced sputum collection at baseline, undergo pulmonary function testing and peripheral blood collection at baseline, 4 and 8 weeks after treatment with inhaled corticosteroids. Receives: Drug: Budesonide |
| Asthmatics (no treatment) | No intervention | Steroid-naïve asthmatics randomized to no treatment for 8 weeks. These subjects will undergo bronchoscopy and induced sputum collection at baseline, undergo pulmonary function testing and peripheral blood collection at baseline, 4 and 8 weeks of no treatment. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline airway epithelial cytokines expression, FEV1 and methacholine PD20 at 4 and 8 weeks
- The baseline expression of airway epithelial cytokines (IL-25, IL-33, TSLP) and/or Th2 cytokines (IL-4, IL-5, IL-13) in bronchial brushing, bronchial biopsy and peripheral blood in healthy control subjects and asthmatic patients.
- Change of forced expiratory volume of the 1st second (FEV1) and accumulated dosage of methacholine provoking a 20% fall of in forced expiratory volume in the first second (FEV1 PD20) of asthmatic patients after treatment with inhaled budesonide or non-intervention for 4 and 8 weeks.
Measured: 8 weeks

Who may be eligible to take part?
The sponsor lists 10 inclusion and 4 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 16 May 2016. 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 China. 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?
Results are not available in the source record.
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 from baseline airway epithelial cytokines expression, FEV1 and methacholine PD20 at 4 and 8 weeks (time frame: 8 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 16 May 2016.
