About this study

Official title: Pilot Study to Assess Effects of Novel Beverages on Established and Novel Risk Markers for Vascular Disease

The purpose of this study is to assess the effects of a novel beverage rich in polyphenols (compounds present in fruit extracts) on risk factors associated with cardiovascular disease.

Read the detailed description

This study will assess the potential of a beverage containing plant and fruit extracts rich in polyphenolics to modulate vascular risk.

Novel risk factors for vascular disease will be assessed including non-invasive assessment of vascular function by pulse wave analysis / pulse wave velocity and laser doppler iontophoresis.

Being tested
High polyphenol beverage, Placebo Beverage
Keywords
polyphenolics, flavonols, lipids, endothelial function, vascular risk factors
Medical subject headings

Questions about this trial

What is this clinical trial studying?

A study testing High polyphenol beverage in people with Cardiovascular Disease, run by University of Glasgow at 1 site in United Kingdom.

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 2 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: status not confirmed, as of the sponsor's last update on 21 Nov 2008. 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 Kingdom. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Adam WF Mullan, MBChB MRCP (+44-141-330-2569, a.mullan@clinmed.gla.ac.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Vascular Function (measured by Laser Doppler Iontophoresis and Pulse Wave Analysis / Pulse Wave Velocity) (time frame: Baseline and post intervention). 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 NCT00795834, 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 21 Nov 2008.
