About this study
The purpose of this study is to measure the density of a temperature-sensitive protein, named TRPV1, in the airway mucosa tissue of both non-asthmatic and moderate to severe persistent asthmatic patients. This study may generate information for developing new therapeutic strategy.
Read the detailed description
The research procedure will be conducted at University of Kentucky A.B. Chandler Hospital dedicated bronchoscopy suite located on third floor of Pavilion H module room #2, and will be performed only once as part of a standard of care bronchoscopy procedure scheduled by the participants pulmonary physician. This entire study (biopsy) will add 10 minutes or less. Following the biopsy, and after being discharged from the hospital, the participant's study participation will end.
Bronchial Biopsy: The investigator will collect five lung (bronchial) specimens (1-2 cubic millimeters each) from three zones of the participant's airway which will be individually coded, and stored for the computer image analysis of TRPV1 in the investigator's laboratory. Following analysis the samples will be destroyed. The results of the analysis cannot be used for determining a clinical diagnosis. Therefore, the investigator will not provide any findings to either the participant or their physician.
Participants will not get any personal benefit from taking part in this study. Their willingness to take part in this research study, may, in the future help doctors better understand and/or treat patients with asthma.
There will be no cost to the participant for having the bronchial biopsy performed.
Participants will not receive any rewards or payment for taking part in the study.

- Moderate Persistent Asthma, Severe Persistent Asthma, Nodule Solitary Pulmonary, Pulmonary Atelectasis

Questions about this trial
What is this clinical trial studying?
A study testing Bronchial biopsy in people with Moderate Persistent Asthma and Severe Persistent Asthma, run by Lu Yuan Lee 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 7 inclusion and 11 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The record says: withdrawn, as of the sponsor's last update on 14 Jun 2021. 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 withdrawn before enrolling participants, so there are no results.
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?
TRPV1 density in airway mucosa tissue (time frame: one year). 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 14 Jun 2021; AzTrials last refreshed its copy on 8 Nov 2026.
