Middle Term Effect of Red Yeast Rice on Plasma Lipids and Proteoma in Individuals With Suboptimal Cholesterolemia

April 10, 2024 updated by: Arrigo F.G. Cicero, University of Bologna

Randomized Clinical Trial to Evaluate the Middle Term Effect of a Dietary Supplement Containing Red Yeast Rice (Total Monacolin <3 mg/Dose) or Placebo on Plasma Lipids and Proteoma in Subjects With Suboptimal Cholesterolemia

The primary purpose of our research will be to evaluate if, in healthy subjects with a low- moderate cardiovascular risk (CV risk>1% but < 5%) evidenced by sub-optimal cholesterol levels as per ESC/EAS guidelines (LDL cholesterol >115 mg/dL, < 190 mg/dL) supplementation with a red yeast rice food supplement containing less than 3 mg total monacolins per daily dose is able to significantly influence plasma lipid levels. Furthermore, liver and muscle proteomic pattern and vascular response to dietary supplementation will be investigated.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Male or female aged ≥ 30 years and ≤ 70 years old.
  • Body Mass Index included between 18 Kg/m2 and 35 Kg/m2
  • Total cholesterolemia between 200 and 280 mg/dL and/or LDL-Cholesterol between 130 mg/dL and 190 mg/dL.
  • TG<400 mg/dL.
  • Subjects who, according to the SCORE charts, have a low or moderate cardiovascular risk (defined as a total cardiovascular risk < 5%) and for whom, according to ESC/EAS guidelines 2012, the intervention strategy does not require a pharmacological lipid-lowering intervention.
  • Subjects who have the capability to communicate, to make themselves understood, and to comply with the study's requirements.
  • Subjects agree to participate in the study and having dated and signed the informed consent form.

Exclusion Criteria:

  • Assumption of lipid lowering drugs or dietary supplements, or drugs potentially affecting the lipid metabolism;
  • Assumption of any kind of drug treatment non-stabilized for at least 3 months;
  • Known current thyroid, gastrointestinal or hepatobiliary diseases (including liver transaminases ≥3ULN), as well as any muscular disorders (even subclinical, including serum CPK ≥3ULN);
  • Current or previous alcohol abuse;
  • Pregnancy and Breastfeeding
  • Known previous intolerance to red yeast rice
  • History or clinical evidence of any significant concomitant disease that could compromise the safety of the subject or the possibility of completing the study;
  • Any medical or surgical condition that would limit the patient adhesion to the study protocol.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treatment-dependent change in LDL-C
Time Frame: 6 weeks
The primary objective is to evaluate the effect of the tested dietary supplement containing less than 3 mg of total monacolins per daily dose on LDL cholesterol level versus placebo after 6 weeks of treatment vs placebo in healthy subjects with suboptimal cholesterolemia
6 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Treatment-dependent change in Total Cholesterol
Time Frame: 6 weeks
To compare the effect of the tested dietary supplement on total cholesterol level after 6 weeks of treatment vs placebo vs placebo in healthy subjects with suboptimal cholesterolemia
6 weeks
Treatment-dependent change in Non-HDL-C
Time Frame: 6 weeks
To compare the effect of the tested dietary supplement on Non-HDL cholesterol level after 6 weeks of treatment vs placebo vs placebo in healthy subjects with suboptimal cholesterolemia
6 weeks
Treatment-dependent change in liver parameters
Time Frame: 6 weeks
To evaluate if the tested dietary supplement is associated with changes in liver parameters (i.e. AST, ALT, gamma-GT) vs placebo in healthy subjects with suboptimal cholesterolemia
6 weeks
Treatment-dependent change in CPK plasma levels
Time Frame: 6 weeks
To evaluate if the tested dietary supplement is associated with changes in CPK plasma levels compared to placebo in healthy subjects with suboptimal cholesterolemia
6 weeks
Treatment-dependent change in plasma proteomic pattern
Time Frame: 6 weeks
To evaluate if the tested dietary supplement is associated with significant changes on plasma proteomic pattern with focus on liver and muscle protein parameters in healthy subjects with suboptimal cholesterolemia. Protein abundances will be calculated with the generation of spectral features by the node FeatureFinderMultiplex followed by PIA-assisted FDR-multiple scores estimation and filtering (combined FDR score<0.01), their ID mapping and combination with peptide IDs, their subsequent alignment, grouping and normalization (e.g., MapAlignerIdentification, FeatureUnlabeledQT and ConsensusmapNormalizer nodes).
