AIMS: Angiopoietin-like proteins (ANGPTLs) are key regulators of lipid metabolism; however, their response to lipid-lowering therapies remains incompletely understood. The PRESTIGE study compared the effects of pemafibrate add-on versus statin dose doubling on small dense low-density lipoprotein-cholesterol (sdLDL-C) in patients with type 2 diabetes and hypertriglyceridemia receiving statins. This post-hoc analysis investigated changes in circulating ANGPTL levels.
METHODS: Participants were randomized to receive either pemafibrate (0.2 mg/day; n = 48) or double-dose statin therapy (n = 49). Plasma ANGPTL levels and lipid parameters were assessed at baseline and after 12 weeks. ANGPTLs were quantified using specific human ELISA kits. sdLDL-C, LDL-triglycerides (TG), and HDL3-C were measured using the homogeneous assays.
RESULTS: Pemafibrate treatment significantly increased circulating ANGPTL3 (+71%) and ANGPTL4 (+143%) levels, with no change in ANGPTL8, whereas statin dose doubling had no effect on ANGPTL levels. Pemafibrate markedly reduced TGs and sdLDL-C, while increasing large buoyant LDL-C, LDL-TG, HDL2,3-C, apolipoprotein AI, and apolipoprotein AII. The increase in ANGPTL3 was not correlated with changes in LDL subspecies but was positively associated with changes in HDL2,3-C. When participants were stratified by baseline ANGPTL3 levels, those in the low ANGPTL3 group showed an increase in LDL-C and LDL-TG in response to pemafibrate. The substantial elevation in ANGPTL4 induced by pemafibrate did not show associations with lipid changes.
CONCLUSIONS: Pemafibrate markedly elevated circulating ANGPTL3 and ANGPTL4 levels, but these increases were not associated with pro-atherogenic changes in lipoprotein profiles. Notably, baseline ANGPTL3 concentrations may influence the effect of fibrates on LDL-C levels.
