Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 40 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Twenty adult subjects ≥ 40 years of age and ≥ 10 pack/year cigarette history will be evaluated.
  • Subjects will be recruited such that one-half are current smokers and one-half are former smokers.
  • All subjects will have COPD (FEV1/FVC < 70% and FEV1 => 40% predicted).
  • Airway hyperresponsiveness and diffusion capacity for carbon monoxide will also be performed to more precisely characterize the physiologic phenotype in these subjects.

Who cannot join

  • Subjects will be excluded if they have used inhaled or systemic corticosteroid or antibiotic use within 6 weeks or if they are currently treated with theophylline.
  • A 6 weeks run off after an upper respiratory infection will be required for qualifying subjects.

About this study

Official title: Expression of Inflammatory Mediators in Induced Sputum: A Potential Biomarker of Drug Response in COPD

The purpose of this research study is to determine whether analysis of genes in sputum is a useful noninvasive technique for measuring response to drugs in patients with COPD.

We propose to use polymerase chain reaction to evaluate gene expression in induced sputum from adult current smokers with moderate COPD, adult former smokers with moderate COPD. This study is designed to determine whether changes in expression of previously-identified inflammatory markers in induced sputum can be detected in response to drug therapy in COPD and to evaluate potential differences in the expression of these markers in adult smokers with and without COPD. Pre- and post-treatment serum will be obtained to facilitate proteomic analysis of therapeutic response as well. Changes in sputum gene expression in response to treatment will be the primary outcome variable in this study. Secondary outcomes will include changes in lung function, as well as changes in induced sputum inflammation. These endpoints will be evaluated before and directly after 6 weeks of randomly-assigned treatment with either salmeterol xinafoate or fluticasone propionate/50mcg salmeterol xinafoate combination DPI bid. Endpoints will be re-evaluated following a 4 week wash-out period.

Questions about this trial

What is this clinical trial studying?

A study testing Salmeterol or Salmeterol/Fluticasone in people with Chronic Obstructive Pulmonary Disease (COPD) and Emphysema, run by National Jewish Health at 1 site in United States.

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 4 inclusion and 2 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: stopped early, as of the sponsor's last update on 29 Mar 2017. 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 States. 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 was stopped early. 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?

Induced Sputum Gene Expression. 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 29 Mar 2017.
