Apabetalone – Bet Protein Inhibition in Cardiovascular Disease and Type 2 Diabetes
Julia Brandts, Kausik K. Ray
Abstract
Apabetalone is the first selective BET protein inhibitor in the field of cardiovascular diseases (CVD). BET proteins are epigenetic regulators that link upstream epigenetic modifications to downstream gene expression. Inhibition of BET proteins by apabetalone has been shown to modulate reverse cholesterol transport, coagulation, inflammation and vascular calcification. Furthermore, apabetalone reduces circulating markers of CVD risk and plaque vulnerability. Post-hoc pooled analyses suggest a potential reduction in risk of major adverse cardiac events (MACE) in patients with Type 2 diabetes (T2D) and stable CVD. However, the current cardiovascular outcomes trial BET-on-MACE failed to detect the assumed 30% reduction of MACE by apabetalone in patients with T2D after an acute coronary syndrome.
