Pemafibrate for treating MASLD complicated by hypertriglyceridaemia: a multicentre, open-label, randomised controlled trial study protocol.

Introduction: Non-alcoholic fatty liver disease, now known as metabolic dysfunction-associated steatotic liver disease (MASLD), is a phenotype of the metabolic syndrome in the liver and is clearly associated with metabolic abnormalities such as hyperglycaemia and dyslipidaemia. Although the prevalence of MASLD is increasing worldwide, there is currently no consensus on the efficacy and safety of the drugs used to treat MASLD/metabolic dysfunction-associated steatohepatitis (MASH). Pemafibrate, a selective peroxisome proliferator-activated receptor alpha modulator, was designed to have higher peroxisome proliferator-activated receptor alfa (PPARα) agonist activity and selectivity than existing PPARα agonists, and in development trials, without increasing creatinine levels, lipid parameters and alanine aminotransferase (ALT) were significantly improved.
