About this study

The investigators are studying whether an anti-inflammatory intervention improves impaired coronary endothelial function (CEF) in HIV+ people with no clinical coronary artery disease (CAD).

Read the detailed description

Survival in people with HIV has significantly improved with the use of antiretroviral therapy (ART) but HIV+ people now experience an increasing burden of chronic diseases, including coronary atherosclerosis and coronary artery disease (CAD). HIV patients manifest an increased risk of CAD and its consequences possibly due to interplay of inflammation with traditional risk factors (smoking, high cholesterol, and poor diet), some of the latter accentuated by ART.

What the investigators are studying in this program is the function of the coronary arteries and in particular the inner lining of the arteries called the endothelium in patients with HIV. The endothelium has several important functions; one of them is that under conditions of stress it releases a substance called nitric oxide which increases the size of the artery and increases blood flow. When it is not functioning normally the artery does not increase as much and blood flow does not increase during stress.

The investigators study coronary artery function with magnetic resonance imaging, or MRI. MRI is a method of obtaining images of what is happening inside the body. MRI does not involve radiation, x-ray, or injection of contrast. The investigators can measure flow in the artery and the dimension of the artery at rest and with a handgrip stress and learn the extent to which the artery dilates and flow increases with the stress. The investigators believe that inflammation can interfere with normal function and that by decreasing inflammation abnormal endothelial function may be improved.

Colchicine is an anti-inflammatory agent approved by the Food and Drug Administration (FDA) to treat arthritis and some other conditions. This drug is not approved for use to suppress inflammation in patients with coronary artery disease and improve coronary artery endothelial function. The FDA is allowing the use of colchicine or a placebo in this research study.

This study will involve 24 weeks of colchicine or placebo and 3 Magnetic Resonance Imaging (MRI) scans of the heart and other study procedures.

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 3 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: finished, as of the sponsor's last update on 21 Oct 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. 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 phase mean?

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?

Yes. Results are posted in the registry (first posted 19 Aug 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Coronary Endothelial Function Measured by Percent Change in Coronary Blood Flow With Exercise (%) at 8 Weeks (time frame: Difference between measurements at baseline compared to measurement at 8 weeks). 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 NCT02624180, which also lists 9 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 21 Oct 2021; AzTrials last refreshed its copy on 7 Nov 2026.
