About this study

Official title: Evaluation of the Effect of Chokeberry (Aronia Melanocarpa) Polyphenols on Blood Pressure in Prehypertensive Healthy Men and Women

Aronia berries are a native North American berry with high naturally occurring anthocyanins among other polyphenols. Based on their polyphenol composition, there is growing interest in the potential for Aronia berries to elicit health promoting cardio-metabolic effects. Specifically, Aronia berry extracts, which provide a concentrated source of polyphenols, may improve blood vessel function.

Thus, the primary focus of this project is to evaluate the effects of Aronia berry polyphenols on blood pressure and other biomarkers of cardiovascular disease risk such as endothelial function, arterial stiffness and blood lipids.

Being tested
Placebo, Aronia extract
Keywords
(Poly)phenols, Aronia berry, Blood pressure, Vascular function

    Measured: Baseline and 12 weeks

Secondary outcomes (10)
  1. Office blood pressure

    Determine the effect of the Aronia extract vs Placebo on office systolic and diastolic blood pressure, at 12 weeks post consumption

    Measured: Baseline 0 and 2 hours and 12 weeks 0 and 2 hours

  2. Heart rate

    Determine the effect of the Aronia extract vs Placebo on heart rate, at 12 weeks post consumption

    Measured: Baseline 0 and 2 hours and 12 weeks 0 and 2 hours

  3. Flow-mediated dilation

    Determine the effect of the Aronia extract vs Placebo on flow-mediated dilation at 12 weeks post consumption

    Measured: Baseline 0 and 2 hours and 12 weeks 0 and 2 hours

  4. Blood flow velocity

    Determine the effect of the Aronia extract vs Placebo on blood flow velocity at 12 weeks post consumption

    Measured: Baseline 0 and 2 hours and 12 weeks 0 and 2 hours

  5. Pulse wave velocity (PWV)

    Determine the effect of the Aronia extract vs Placebo on pulse wave velocity (PWV) using a Sphygmocor device, at 12 weeks post consumption

    Measured: Baseline 0 and 2 hours and 12 weeks 0 and 2 hours

  6. Augmentation Index (AIx)

    Determine the effect of the Aronia extract vs Placebo on augmentation Index (AIx) using a Sphygmocor device, at 12 weeks post consumption

    Measured: Baseline 0 and 2 hours and 12 weeks 0 and 2 hours

  7. Blood lipids

    Determine the effect of the Aronia extract vs Placebo on blood lipids (Total, HDL and LDL cholesterol, triglycerides), at 12 weeks post consumption

    Measured: Baseline and 12 weeks

  8. Blood cortisol

    Determine the effect of the Aronia extract vs Placebo on blood cortisol levels, at 12 weeks post consumption

    Measured: Baseline and 12 weeks

  9. Number of volunteers with treatment-related adverse events

    The number of volunteers with treatment-related adverse events will be assessed by questionnaires and interviews.

    Measured: Baseline and 12 weeks

  10. 24-hour heart rate

    Determine the effect of the Aronia extract vs Placebo on 24-hour heart rate, using a monitor, at 12 weeks post consumption

    Measured: Baseline and 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Aronia extract in people with Prehypertension and Healthy, run by King's College London at 2 sites 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 6 inclusion and 21 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 23 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

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?

Changes from baseline ambulatory blood pressure after 12-week consumption (time frame: Baseline and 12 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 NCT03434574, 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 23 Sep 2019.
