About this study

Micellar encapsulation will be tested to increase the oral bioavailability in humans of 6-prenylnaringenin (6-PN) from hops (Humulus lupulus). The study follows a single dose (250 mg 6-PN), placebo controlled, randomized, double-blind, three armed crossover study design with ≥2-week washout periods. Plasma, urine and PBMC samples will be collected at intervals up to 24 h after intake of the native compound, the micellar formulation or placebo. The safety, pharmacokinetics and impact of oral prenylflavonoids on PBMC survival will be investigated.

Being tested

Questions about this trial

What is this clinical trial studying?

A study testing Native 6-prenylnaringenin and Micellar 6-prenylnaringenin in people with Safety of Native vs. Micellar 6-PN After Oral Intake and Pharmacokinetics of Native vs. Micellar 6-PN After Oral Intake, run by University of Hohenheim at 2 sites 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 3 inclusion and 8 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 Oct 2018. 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 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. 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?

Mean area under the curve (AUC) of plasma concentration vs. time of total 6-PN [nmol/L*h] (time frame: 0 h, 0.5 h, 1 h, 2 h, 4 h, 6 h, 8 h and 24 h post dose). The study lists 6 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 Oct 2018.
