About this study

At visit one, after the subject has signed the consent form, subjects will answer questions and have maximum reversibility lung function test to determine if they are eligible to proceed with the study. Once the study team has proven that the subject is eligible to proceed the study team will collect a sputum sample and blood sample to study their cells. At visit two the subjects will undergo a research bronchoscopy at this point the study team will collect more samples including a BAL sample and another blood sample. Three follow up phone calls will be conducted after the procedure to ensure subject safety, the study team will record any symptoms that they are experiencing at that time. Throughout this study the samples will be analyzed to see if a larger subset of COPD patients could benefit from using the drug mepolizumab.

Read the detailed description

During this study the subjects will have a bronchoscopy where the study team will collect airway samples to see how the subjects express certain cells. The subjects will also have two blood draws to provide information on the number of inflammatory cells that are present in their blood. This will help the study team determine if mepolizumab might be able to be used in more patients with COPD. The use of mepolizumab in COPD subjects with elevated blood eosinophils has been proven effective. However, the cellular mechanisms in the COPD population are unknown, including the extent to which these subjects express IL-5 in their airway and whether eosinophils are the sole target. Through this study the study team plans to provide proof of concept that mepolizumab could target additional IL-5-expressing immune cells in the airway, including especially PMNs. The study team will also investigate additional feasible biomarkers that could be utilized to predict mepolizumab responsiveness in COPD. The study team is hoping to determine if COPD patients with elevated blood eosinophils will demonstrate increased concentrations of IL-5 in their bronchoalveolar lavage (BAL) fluid and increased expression in their BAL of CD125+ PMNs. To address this hypothesis, the following specific aims will be addressed: To define the expression of IL-5R on PMNs in COPD and to demonstrate elevated concentrations of IL-5 in BALF obtained from COPD subjects with blood eosinophils (≥300/µL).

    Measured: within 24 hours

  2. IL-5 concentration in BALF

    IL-5 will be quantified in bronchoalveolar lavage fluid

    Measured: within 24 hours

Questions about this trial

What is this clinical trial studying?

A study testing Bronchoscopy in people with COPD, run by University of Virginia 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 8 inclusion and 9 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 18 May 2022. 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 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?

IL-5R expression on bronchial neutrophils (time frame: within 24 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03984799, which also lists 1 linked publication.

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 18 May 2022.
