Berberol P for Mild-to-Moderate Hypercholesterolaemia

This randomized, controlled, multicentre clinical trial will evaluate the efficacy and safety of Berberol® P compared with Berberol® K in adults with mild-to-moderate hypercholesterolaemia.

A total of 255 participants will be randomized in a 1:1:1 ratio to receive Berberol® P 1 tablet daily, Berberol® P 2 tablets daily, or Berberol® K 1 tablet daily for 12 weeks. The study will primarily assess whether Berberol® P is non-inferior to Berberol® K in reducing low-density lipoprotein cholesterol (LDL-C). Changes in other lipid parameters, glucose metabolism, anthropometric measures, blood pressure, and safety will also be evaluated.

About this study

Hypercholesterolaemia is an important modifiable cardiovascular risk factor. Nutraceutical approaches may provide an option for individuals with mild-to-moderate hypercholesterolaemia, particularly when lifestyle measures alone are insufficient.

This is a randomized, controlled, multicentre, three-arm clinical trial evaluating two daily doses of Berberol® P compared with Berberol® K. Eligible participants will be randomized in a 1:1:1 ratio to one of three treatment groups: Berberol® P 1 tablet daily, Berberol® P 2 tablets daily, or Berberol® K 1 tablet daily. Treatment will continue for 12 weeks.

The primary objective is to evaluate the non-inferiority of Berberol® P compared with Berberol® K with respect to the change in LDL-C after 12 weeks of treatment. The study will also evaluate effects on the lipid profile, glucose metabolism, anthropometric parameters and blood pressure, as well as the safety and tolerability of the interventions.

A total of 255 participants are planned to be enrolled across multiple study centres.
