Study Summary

The goal of this clinical trial is to learn if berberine works to affect lipids and lipoproteins in Chinese females aged 20 to 65 years with hyperlipidaemia. The goal also includes to examine the sex-specific effect of berberine on lipids and lipoproteins. Our previous HMRF-funded randomized trial in men and prior evidence suggests berberine affects sex hormones. Given the different sex hormone profiles in men and women, the main question it aims to answer is:

• Does berberine have sex-specific lipid-modifying effects? Researchers will compare berberine to a placebo (a look-alike substance that contains no drug) to see if berberine works to affect lipids and lipoproteins.

Participants will:

Take a baseline questionnaire
Take berberine or a placebo every day for 12 weeks
Take follow-up visits after 8 weeks and 12 weeks for blood sample collections and tests

Study Description

The overall aim of the project is to assess the sex-specific effects of berberine on lipids, apoA1, apoB, and Lp(a). Specifically, the objectives of the project are to 1) assess the effect of berberine on lipids (total cholesterol, LDL-cholesterol, HDL-cholesterol, non-HDL cholesterol, and TG), lipoproteins (apoA1, apoB, and Lp(a)) and sex hormones by conducting a randomized, parallel, double-masked, placebo-controlled trial of berberine RCT in women; 2) assess the effect of berberine on apoA1, apoB, Lp(a) and sex hormone binding globulin (SHBG) in men using stored samples from our completed RCT of berberine in men; 3) assess whether the effects of berberine on lipids, lipoproteins and sex hormones differ in men and women.

This is a randomized, parallel, double-blinded, placebo-controlled trial of berberine in 100 Chinese women with hyperlipidemia in Hong Kong.

Participants will be randomized to two arms in which half of the participants will receive berberine (500 mg orally twice a day) and the other half will receive placebos (500 mg orally twice a day) for 12 weeks. Blood samples will be taken at baseline, 8-week and 12-week intervention.

The investigators will use an intention-to-treat analysis. Changes in lipids and lipoproteins after 8- and 12-week treatment will be assessed using analysis of variance and generalized estimating equation (GEE) model accounting for measurements at both time points.
