Efficacy and Safety of Pemafibrate, a Novel Selective PPARα Modulator in Chinese Patients with Dyslipidemia: A Double-Masked, Randomized, Placebo- and Active-Controlled Comparison Trial.

AIMS

Pemafibrate substantially lowers serum triglyceride (TG) levels and increases high-density lipoprotein cholesterol (HDL-C) levels primarily in Japan, but it has not been evaluated in China. We aimed to confirm the efficacy and safety of pemafibrate in Chinese patients with hypertriglyceridemia and low HDL-C levels by comparing placebo and fenofibrate.

METHODS

A multicenter, double-masked trial was conducted in China involving 344 patients with high TG and low HDL-C levels randomly assigned to one of four groups: pemafibrate 0.2 mg/d, pemafibrate 0.4 mg/d, fenofibrate 200 mg/d, or placebo for 12 weeks. The primary endpoint was the percentage change in fasting TG levels.

RESULTS

The percentage change in TG levels from baseline was -34.1%, -44.0%, -30.5%, and 6.5% in the pemafibrate 0.2 mg/d, pemafibrate 0.4 mg/d, fenofibrate 200 mg/d, and placebo groups, respectively. Pemafibrate 0.4 mg/d significantly reduced TG levels compared with that in both placebo (p＜0.0001) and fenofibrate groups (p=0.0083). Significant improvements in HDL-C, remnant cholesterol, and apolipoprotein A1 levels were also observed with both doses of pemafibrate than with the placebo. Pemafibrate showed significantly smaller changes in alanine aminotransferase, aspartate aminotransferase, and serum creatinine levels than those with fenofibrate.

CONCLUSIONS

In Chinese patients, pemafibrate exhibited superior efficacy in improving TG levels and enhanced hepatic and renal safety compared to fenofibrate. Thus, pemafibrate may represent a promising therapeutic option for dyslipidemia in Chinese patients.
