About this study

Official title: Effect of Iso-alpha-Acids and Xanthohumol on Inflammatory Processes in Human

The aim of the present study is to determine the effect of Xanthohumol and Iso-alpha-acids from hops on the immune response of healthy participants.

Read the detailed description

In this placebo-controlled crossover study a study drink enriched with either a placebo, Xanthohumol, Iso-alpha Acids or a combination of latter is given to the participants. A washout phase before intervention and between each intervention is introduced. On day one of each intervention blood is drawn in fasted state from each participant. Subsequently the study drink combined with a standardized breakfast is given to the participants following a second blood drawing one hour after the consumption of the study drink. On the last day of each intervention blood is taken from study participants in the same manner as on day one. To assess the effect of Xanthohumol and Iso-alpha acids or a combination of both, clinical chemical parameters e.g. ALT, AST, γ-GT, blood lipids (triglycerides, total cholesterol, HDL, LDL), blood glucose, uric acid and CRP are determined. Furthermore, PBMC's isolated from blood samples of each time point were stimulated for either 24 or 48 h. Protein levels and mRNA expression of markers of inflammation is measured in PBMC's and supernatant of stimulated cells.

Being tested
Dietary Intervention 1: Placebo, Dietary Intervention 2: Xanthohumol and Iso-alpha acids

Questions about this trial

What is this clinical trial studying?

A study testing Dietary Intervention 2: Xanthohumol and Iso-alpha acids in people with Inflammatory Response, run by University of Vienna at 1 site in Austria.

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 1 inclusion and 1 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 22 Mar 2022. 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 Austria. 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?

Changes in parameters of immune response (time frame: 5 days). 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 NCT04847193, which also lists 2 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 22 Mar 2022.
