Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Asymptomatic carotid artery disease on at least one side with a degree of stenosis > 25% (according to on the ECST criteria). If the patient has a symptomatic carotid artery disease on the contra-lateral side, he/she will still be included in the study, if intensified medical treatment for this symptomatic stenosis (e.g. statins, antiplatelet medication) was started ≥ 6 month before inclusion of the patient. This protocol was chosen in order to widely assure a stable situation on the plaque(s), which avoids an overspill from this medication on the assumed effects of the MK-7 and vitamin D3 supplementation.
  • Age older than 18 years
  • Signed informed consent provided

Who cannot join

  • Antiplatelet or cholesterol lowering medication started within the past 6 months
  • Chronic or paroxysmal atrial fibrillation
  • Presence or scheduled coronary or carotid revascularisation procedure (e.g. stent implantation, coronary artery bypass graft, balloon-dilatation, endarterectomy, angioplasty)
  • History of myocardial infarction or stroke
  • Malignant disease (except for treated basal-cell or squamous cell carcinoma)
  • Use of vitamin K antagonists or any other anticoagulation treatment

About this study

Official title: Effects of Vitamin K2 and D3 Supplementation on 18F-NaF PET/MRI in Patients With Carotid and Coronary Artery Disease

Atherosclerosis is a disease of the arteries and is the result of various factors such as high blood cholesterol or diabetes, which lead to accumulations of fats, cells, and calcium deposits (i.e. plaques). It has been shown that people with a rapid increase in the amount of calcium deposits have a higher risk for stroke and heart attack than people with a decreased amount.

Previous scientific research has shown that a protein called Matrix Gla Protein plays an important role in the prevention of calcification. This protein works well only if there is enough Vitamin K in the blood vessels. In a large human studies, it has been shown that especially MK-7 (a form of Vitamin K2) is best absorbed by blood vessels. Moreover, studies suggest positive effects of vitamin D (especially D3) on vitamin K-dependent metabolism.

Over the last years, fluorine-18 sodium fluoride (18F-NaF) positron emission tomography (PET) emerged as a reliable clinical imaging tool able to detect micro-calcification in the blood vessels. Therefore, the present study will use 18F-NaF PET in combination with magnetic resonance imaging (MRI) to assess the influence of vitamin K and D supplementation in the development of arterial micro-calcification in the context of atherosclerosis.

The present study would like to confirm that MK-7 and vitamin D3 supplementation induces a significant reduction in the degree of micro-calcification from carotid artery disease patients, when comparing to a placebo, after 3 months.

This will be a prospective double blind randomised controlled feasibility study, in which one group will receive a MK-7 and vitamin D3 supplementation compared to a control group receiving a placebo.

What is being measured

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

  1. The change in time of vascular micro-calcification via (18)F-NaF PET/MRI

    The primary outcome of this study is the mean rate of the change in time of vascular micro-calcification in the carotid arteries, measured as a difference between the intervention group and placebo group in (18)F-NaF uptake via hybrid PET/MRI after the 3 months of treatment.

    Measured: 3 months follow-up

Secondary outcomes (3)
  1. The change in time of vascular calcification via coronary artery calcification score

    Investigating whether MK-7 and vitamin D3 supplementation can diminish, halt or even reverse the development of arterial micro-calcification in the coronary arteries, measured as a difference between the intervention group and placebo group in coronary artery calcification score after the 3 months.

    The Agatston coronary artery calcification score isis a semi-automated tool to calculate a score based on the extent of coronary artery calcification detected by an non-contrast low-dose CT scan. The score ranges from 0 arbitrary units to > 400. The higher the value of the score, the higher the degree of calcification is in the coronary arteries; hence, lower values usually represent a better outcome.

    Measured: 3 months follow-up

  2. The correlation between (18)F-NaF PET/MRI and coronary artery calcification score

    The correlation between the uptake of (18)F-NaF at 3 months and the coronary artery calcification score.

  3. The influence of MK-7 and vitamin D3 supplementation on MRI parameters

    Investigating whether MK-7 and vitamin D3 supplementation can influence the fibrous cap status on the MRI.

    Measured: baseline vs 3 months follow-up

Questions about this trial

What is this clinical trial studying?

A study testing MK-7 and vitamin D3 in people with Coronary Artery Disease and Carotid Artery Disease, run by Academisch Ziekenhuis Maastricht.

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 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: status not confirmed, as of the sponsor's last update on 21 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

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.

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

Contact Felix M Mottaghy, MD, PhD (+31 43 3874746, felix.mottaghy@mumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The change in time of vascular micro-calcification via (18)F-NaF PET/MRI (time frame: 3 months follow-up). 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 21 Sep 2023.
