About this study

Official title: A Double-blind, Randomized, Placebo-controlled, Cross - Over Design, Single Center Study to Evaluate the Effects of Treatment With Pycnogenol® on Endothelial Function in Subjects With Stable Coronary Artery Disease (Pycno2007-003)

Pycnogenol® is a proprietary bark extract of the French maritime pine tree (Pinus pinaster ssp. atlantica). Pycnogenol® has prevented pathologic symptoms such as chronic inflammation and increased platelet aggregation, a risk factor for cardiovascular diseases. The endothelium is increasingly recognized not only a target (with vascular remodelling occurring in response to an injury and resulting in atherosclerosis), but also a mediator in the pathogenesis of atherosclerosis. Indeed, endothelial cells play an important regulatory role in the cardiovascular system by the expression of numerous molecules and release of mediators such as nitric oxide (NO), superoxide and endothelin-1 (ET-1). Data from animal studies, as well as human studies indicate that Pycnogenol may improve endothelial function, which is a powerful surrogate for clinical prognosis.

Questions about this trial

What is this clinical trial studying?

A study testing Pycnogenol in people with Coronary Artery Disease, run by University of Zurich at 1 site in Switzerland.

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 22 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 10 Feb 2010. 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 Switzerland. 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.

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?

The primary objective of this study is to evaluate the effects of treatment with Pycnogenol® on endothelial function in subjects with stable coronary artery disease. (time frame: 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 NCT00641758, 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 10 Feb 2010.
