Effect of Totum-070 on Lipid Metabolism in Moderate Hypercholesterolemic Subjects

Randomized Placebo-controlled Double-blinded Study of the Effect of TOTUM-070 on Lipid Metabolism in Moderate Hypercholesterolemic Subjects

This clinical study aims to assess the efficacy of TOTUM-070, a mix of 5 plant extracts, on lipid metabolism in moderate hypercholesterolemic subjects. The hypothesis is that TOTUM-070, daily consumed, is superior to placebo for decrease of fasting blood LDL-cholesterol concentration (determined by ultracentrifugation method) after 24 weeks of consumption.

Inclusion Criteria:

• I1. From 18 to 70 years (including ranges);
• I2. Body mass index (BMI) between 18.5 and 35 kg/m² (including ranges);
• I3. Moderate hypercholesterolemic subject without any clinical symptoms of hypercholesterolemia (xanthoma, recurrent chest and/or leg pain) and not requiring immediate pharmacological lipid-lowering treatment according to the current recommendations (ESC/EAS, 2019);
• I4. For women: Non-menopausal with the same reliable contraception since at least three months before the beginning of the study and agreeing to keep it during the entire duration of the study (hormonal contraception, intra uterine device or surgical intervention) or menopausal with or without hormone replacement therapy (estrogenic replacement therapy begun from less than 3 months excluded);
• I5. Weight stable within ± 5% in the last three months;
• I6. No significant change in food habits or in physical activity in the 3 months before the randomization and agreeing to follow hygiene and dietary (HD) recommendations given during the study;
• I7. Good general and mental health according to the opinion of the investigator: no clinically significant and relevant abnormalities of medical history or physical examination;
• I8. Able and willing to participate to the study by complying with the protocol procedures as evidenced by his dated and signed informed consent form;
• I9. Affiliated with a social security scheme;
• I10. Agreeing to be registered on the volunteers in biomedical research.

At V0 biological analysis, the subjects will be eligible to the study on the following criteria:

• I11. Fasting blood LDL cholesterol concentration (using Friedewald estimation method) between 1.3 and 1.9 g/L (included ranges with ± 2% tolerated around);
• I12. Fasting blood triglycerides concentration ≤ 2.2 g/L;

• E8. Under cholesterol and/or lipid-lowering treatment (e.g. statins, fibrates, ezetimibe, bile acid sequestrants, niacin, etc.) or stopped less than 3 months before the inclusion visit V0;
• E9. Under medication which could affect blood lipid parameters (e.g. long-term corticosteroid systemic drug, systemic antibodies, androgen or enzyme inducer, etc) or stopped less than 3 months before the inclusion visit V0 (antihypertensive stable long-term treatment tolerated);
• E10. Regular intake of dietary supplements or "health foods", or products rich in plant stanol or sterol (like Pro-Activ® or Danacol® products), rich in long chain omega-3 fatty acids (especially soft gels containing fish oils), or in other substances intended to reduce cholesterol or glycemia or stopped less than 3 months before the inclusion visit V0;
• E11. Under treatment or dietary supplement which could significantly affect parameter(s) followed during the study according to the investigator or stopped in a too short period before the randomization (for example consumed in the month before the randomization);
• E12. With a known or suspected food allergy or intolerance or hypersensitivity to any of the study products' ingredient;
• E13. Consuming more than 3 standard drinks daily of alcoholic beverage for men or 2 standard drinks daily for women or not agreeing to keep his alcohol consumption habits unchanged throughout the study;

• E22. Presenting a psychological or linguistic incapability to sign the informed consent;
• E23. Impossible to contact in case of emergency.
