Apabetalone (RVX-208) is an epigenetic regulator developed to treat
cardiovascular disease (CVD) that targets BET proteins. Through transcriptional
regulation RVX-208 modulates pathways that underlie CVD including reverse
cholesterol transport, vascular inflammation, coagulation, and complement. Using
transcriptomics and proteomics we show that complement is one of the top pathways
downregulated by RVX-208 in primary human hepatocytes (PHH) and in plasma from
CVD patients. RVX-208 reduces basal and cytokine-driven expression of complement
factors in PHH and in chimeric mice with humanized livers. Plasma proteomics of
CVD patients shows that RVX-208 decreases complement proteins and regulators,
including complement activators SAP and CRP. Circulating activated fragments C5a,
C3b, and C5b-C6 are reduced by 51, 32, and 10%, respectively, indicating
decreased activity of complement in patients. As complement components are linked
to CVD and metabolic syndrome, including major acute cardiac events, modulating
their levels and activity by RVX-208 may alleviate risks associated with these
diseases.
