About this study

Official title: Bioavailability of Maqui Berry Extracts (Delphinol® / MaquiBright®) in Healthy Subjects

The aim of the present study is to describe the bioavailability for the proprietary standardized maqui berry extracts Delphinol® and MaquiBright® enriched in anthocyanins and in particular delphinidins. The analyses are based on two selected key substances namely delphinidin-3-glucoside and cyanidin-3-sambubioside and their metabolism to phenolic acids.

The bioavailability of anthocyanins specific for Delphinol®/MaquiBright® was analyzed in plasma sample kinetics (at 0h, 0.5h, 1h, 1.5h, 2h, 3h, 4h, 6h and 8h after intake of 1000mg standardized maqui berry extract in capsules) in 12 healthy subjects.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Quantification of two specific maqui berry anthocyanins: namely Delphinidin-3-O-glucoside and Cyanidin-3-O-sambubioside in a kinetics, evaluating the change between baseline and selected time points (see below).

    Specific anthocyanins related to maqui berry extract (Delphinol® / MaquiBright®) were measured in plasma samples of healthy subjects and assessed as change to baseline. Method: LC-MS/MS (unit [nmol/L]).

    Measured: Kinetics: baseline to 0.5 hours, 1 hour, 1.5 hours, 2 hours, 3 hours, 4 hours, 6 hours and 8 hours after intake

  2. Quantification of two specific maqui berry anthocyanin derived metabolites: namely gallic acid and protocatechuic acid in a kinetics, evaluating the change between baseline and selected time points (see below).

    Specific anthocyanin derived metabolites related to maqui berry extract (Delphinol® / MaquiBright®) were measured in plasma samples of healthy subjects and assessed as change to baseline. Method: LC-MS/MS. Results will most probably be assessed as "AUC" (area under the curve).

    Measured: Kinetics: baseline to 0.5 hours, 1 hour, 1.5 hours, 2 hours, 3 hours, 4 hours, 6 hours and 8 hours after intake

  3. Ferric reducing ability of plasma (FRAP) measurement in a kinetics, evaluating the change between baseline and selected time points (see below).

    The FRAP assay was performed to assess the "antioxidant power" / "antioxidant capacity" of the plasma after intake of maqui berry extract (Delphinol® / MaquiBright®). Method: photometric / absorption maximum at 593 nm (unit [µmol/l])

    Measured: Kinetics: baseline to 0.5 hours, 1 hour, 1.5 hours, 2 hours, 3 hours, 4 hours, 6 hours and 8 hours after intake

Questions about this trial

What is this clinical trial studying?

An observational study of Bioavailability, run by Anklam Extrakt at 1 site in Germany.

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 15 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 Jan 2019. 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 Germany. 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. 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?

Quantification of two specific maqui berry anthocyanins: namely Delphinidin-3-O-glucoside and Cyanidin-3-O-sambubioside in a kinetics, evaluating the change between baseline and selected time points (see below). (time frame: Kinetics: baseline to 0.5 hours, 1 hour, 1.5 hours, 2 hours, 3 hours, 4 hours, 6 hours and 8 hours after intake). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Jan 2019.
