About this study

Official title: Effects of 10-gram Collagen Protein Hydrolysate on Cardiometabolic Health in Obese (BMI 25-35 kg/m2) Men and Women With Elevated Risk to Develop Type-2 Diabetes and CVD

The effects of a 10g/day collagen hydrolysate for a period of 4 weeks on glycemic control and cardiovascular health in a parallel design study using overweight/ obese men and women who are likely to have a disturbed lipid and glucose metabolism and increased risk to develop cardiovascular disease and/or Type- 2 diabetes.

Read the detailed description

Food-derived bioactive peptides represent a source of health-enhancing components that have been reported to have cardiovascular health benefits in humans and may be incorporated in functional foods. Up till now studies using collagen hydrolysates particularly addressed issues around joint health, however, there are some preliminary indications that other health-related targets might be affected as well. We here propose to focus on the potential effects of collagen hydrolysates on glycemic control, and characteristics of the microcirculation, both important parameters for the assessment of future cardiovascular disease (CVD) risk.

Being tested
10 g of collagen hydrolysate, Placebo

What is being measured

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

  1. Chronic glucose metabolism

    Measured by change in average daily glucose concentrations over a 15 hours period between waking up and going to bed 7:00-22:00 for three days, which is calculated based on the total area under the curve (tAUC) using a continuous glucose monitor.

    Measured: 2 weeks pre-intervention + 4 weeks intervention: Pre-intervention (visit 3), and immediately after the intervention (visit 5)

  6. Quality of life questionnaire

    Assessed with a 32-item questionnaire (including social, spiritual, emotional, cognitive, physical, activities of daily living, and integrated quality of life) Outcome Measures 1-5 (1= Bad, 2=Below Average, 3= Average, 4=Above Average, 5=Good .

    Measured: 2 weeks pre-intervention + 4 weeks intervention: Pre-intervention (visit 3), during (at home), and immediately after the intervention (visit 5)

  7. Mood, degree of pleasantness and arousal

    Measured: 2 weeks pre-intervention + 4 weeks intervention: Pre-intervention (visit 3), during (at home), and immediately after the intervention (visit 5)

  8. Perceived Stress Scale

    Assessed using the Perceived Stress Scale Scale, a 10-item questionnaire that is used to determine individual stress levels experienced in the past weeks during daily activities. Scores ranging from 0-40 Scores ranging from 0-13 would be considered low stress. Scores ranging from 14-26 would be considered moderate stress. Scores ranging from 27-40 would be considered high perceived stress.

Questions about this trial

What is this clinical trial studying?

A study testing 10 g of collagen hydrolysate in people with Glucose Metabolism and Lipid Metabolism, run by Maastricht University Medical Center at 1 site in Netherlands.

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 20 inclusion and 18 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 18 Nov 2023. 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 Netherlands. 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?

Chronic glucose metabolism (time frame: pre- intervention and during the fourth week of intervention.). 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 NCT05282641, which also lists 9 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 18 Nov 2023.
