About this study

Official title: A Phase I, Randomized, Crossover, Double-blind, Pharmacokinetic Study of Berberine Released From Cyclodextrin in Healthy Volunteers

In this study, we will evaluate the relative bioavailability of Berberine (BB) from capsules containing Indian Barberry (Berberis aristate DC.) Bark and Root Extract in the blood plasma of healthy subjects after oral administration of:

  1. Capsules containing Berberine and GCD (BBA Berberine MetX™ Ultra Absorption, 250 mg) B. Capsules containing Berberine (BB, Berberine MetX™, 500 mg) - (reference product).
Read the detailed description

Study Background

A growing body of evidence suggests that gamma-cyclodextrin (GCD) can increase the clinical efficacy of water-insoluble biologically active compounds with low bioavailability. GCD is the most bio adaptable and helpful to increase the absorption of many drugs, including Berberine from Indian Barberry (Berberis aristate DC.) Bark and Root Extract by forming inclusion complexes or GCD/drug conjugates.

Berberine has been recommended in traditional practice and recognized by modern science to support healthy blood sugar†, cholesterol and triglyceride levels, and overall metabolic health. But despite these findings, standard Berberine can still be difficult for the body to absorb and use effectively.

It's estimated that only about five percent of any given dosage of Berberine makes it into the bloodstream, so finding a way to enhance absorption is key to the full advantage of its benefits.

Hypothesis: gamma-cyclodextrin increases absorption and bioavailability of Berberine from Berberine MetX™ Ultra Absorption capsules.

The study aims to provide experimental evidence supporting or rejecting this hypothesis.

This will be a double-blind, crossover design, pharmacokinetic study, where 16 healthy human volunteers will be randomly assigned to receive two different formulations BBA, and BB, in two consecutive phases of the study:

  • Phase A. All patients take capsules BBA., provide blood samples in 0.5, 0.75, 1, 2, 4, 6, 12, 24, and 48 hours (9 points) after administration following washout period for two weeks.
  • Phase B. All patients take capsules BB, provide blood samples in 0.5, 0.75, 1, 2, 4, 6, 12, 24, and 48 hours (9 points) after administration following washout period for two weeks.

Subjects will be in the clinic from not less than 11 hours pre-dose to ensure at least 10 hours fasting before administering the investigational product. They will remain in the facility post-dose until at least 24 hours each period, provided they are not suffering from any adverse event.

The concentration of Berberine in all blood samples will be determined using a validated for a limit of detection, accuracy, and precision analytical method (HPLC-MS) with the internal standard - digoxin. Appropriate mathematical methods and Kinetic 4.4.1 software will be used to generate basic pharmacokinetic parameters.

The sponsor lists 3 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: opening soon, as of the sponsor's last update on 14 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Armenia, Sweden. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Alexander G. Panossian, PhD (+46733306226, ap@phytomed.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The area under the plasma concentration versus time curve (AUC, expressed in ng x h/mL) of berberine incorporated in gamma-cyclodextrin (time frame: 0.5, 0.75, 1, 2, 4, 6, 12, 24, 48, 72 and 96 hours, post-dose). The study lists 2 primary outcomes in all. 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 NCT04918667, which also lists 7 linked publications.

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 14 Sep 2023.
