Abstract

Pegozafermin (PGZ), a novel glycopegylated version of human fibroblast growth factor 21 (FGF21), has demonstrated potential for addressing metabolic comorbidities, including severe hypertriglyceridemia, insulin resistance, nonalcoholic fatty liver disease, and obesity. FGF21 is a naturally occurring peptide hormone primarily produced by the liver, with a half-life of 0.5 to 2 hours. It can influence metabolic processes through endocrine cellular effects. FGF21 receptors are found in the liver, adipose, skeletal muscles, and pancreatic tissues. Those receptors rely on the beta klotho (KLB) coreceptors, a transmembrane protein, to activate the FGF21 signaling pathway and FGF21’s associated transcription factors. PGZ, through its extended half-life of 55 to 100 hours, has evidenced significant improvements in metabolic functions. Its mechanism of action includes promoting adiponectin levels, enhancing insulin sensitivity, increasing triglyceride uptake, and reducing de novo lipogenesis. This emerging pharmaceutical compound has shown promise in treating liver fibrosis and inflammation linked to nonalcoholic steatohepatitis. The ENTRIGUE trial, a phase 2 clinical trial of PGZ, has demonstrated a 57% reduction in triglyceride level compared to placebo; a 45% reduction in liver hepatic steatosis; improved insulin sensitivity; reductions in nonhigh-density lipoprotein-cholesterol; and reductions in apolipoprotein B-100.
