About this study
Official title: Impact of Quercetin on Inflammatory and Oxidative Stress Markers in COPD
This study determines whether quercetin supplementation reduces the inflammation and oxidative stress markers in patients with chronic obstructive pulmonary disease. It is small study with 8 subjects receive quercetin 2000 mg/day and 4 subjects receive placebo.
Read the detailed description
Chronic obstructive pulmonary disease (COPD) is a progressive lung disorder and affects millions of people globally. Although the exact mechanisms of pathogenesis of this disease are not well-understood, the general consensus is that oxidative stress and inflammation induced by exposure to cigarette smoke or other environmental or occupational hazards are responsible for development of COPD. Therefore, therapies aimed at decreasing oxidative stress and inflammation constitutes an important component of treating COPD.
The current pharmacological therapies may provide temporary symptom relief, reduce acute exacerbations and hospitalizations, but are associated with side effects. Therefore complementary method of treatment with potentially fewer side effects and relatively well-tolerated provide promising alternative. One such compound is quercetin, which is plant polyphenol and is present in variety of foods that we consume. Quercetin has potent antioxidant and anti-inflammatory properties and reduces oxidative stress and inflammation in a preclinical model of COPD. Quercetin exerts it antioxidant properties not only by neutralizing free radical species, but also by enhancing the expression of antioxidant enzymes. Similarly, quercetin inhibits various protein and lipid kinases by competing for adenosine triphosphate (ATP) binding sites thus reducing the inflammatory pathways.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Quercetin in people with Chronic Obstructive Pulmonary Disease, run by Temple University 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 16 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 Aug 2023. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Contact Umadevi Sajjan, Ph.D (2157077139, Uma.Sajjan@temple.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Oxidative stress markers (time frame: six months). 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 NCT03989271, which also lists 5 linked publications.
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 Aug 2023.
