Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Subjects refrained from consuming high polyphenol foods for 48 h prior to the start of the study and for 32 h post initiation. In particular, the following foods and beverages were excluded from volunteer diets: cocoa containing products, coffee, tea and wine. The study was designed as a single blind, randomized, crossover intervention trial, where volunteers were asked to consume either 375 ml of Champagne wine or a placebo matched for alcohol content, sugars and fruit-derived acids. Subjects were assessed for anthropometric measurements and provided a urine sample prior baseline Laser Doppler Imaging with iontophoresis (LDI) measurements. Subjects were then cannulated and a baseline blood sample was collected. Subjects were then randomly assigned to either the Champagne wine or placebo group and asked to consume the beverage within a 10 min period. Following a standardised breakfast blood samples were collected at: 15, 30, 45, 60, 120, 180, 240, 300, 360 and 480 minutes post consumption and pooled urine samples were collected over 3 x 8 h periods. A standardised breakfast and lunch were also consumed at 15 and 200 minutes post beverage. LDI measurements were carried out at 120, 240, 360 and 480 minutes. Subjects also provided 24 h and 32 h blood and urine samples. Following a washout period of 28 days, volunteers returned to the unit to complete the second arm of the study where the procedure above was repeated.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Assessment of endothelial function by Laser Doppler Imaging with iontophoresis. Blood Assessment of lipid profile, inflammatory markers, plasma antioxidant and oxidant capacity, liver enzyme and metalloproteinase blood concentrations.
Time Frame: 6 months
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Bioavailability of phytochemicals and metabolite excretion.
Time Frame: 6 months
6 months

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 1, 2007

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
