Mechanism of action of Lp(a)-lowering siRNA therapy, and potential clinical benefits. GalNAc–siRNA drugs lower circulating Lp(a) concentrations via the mechanisms described in more detail in Figure 2. Evidence from observational and genetic epidemiological studies supports a role for Lp(a) lowering as a means of reducing the risk of several types of cardiovascular disease, including atherosclerotic in the coronary and peripheral circulations, valvular disease and heart failure. siRNA, small interfering RNA; ASGPR, asialoglycoprotein receptor; LPA, apolipoprotein(a) gene; Lp(a), lipoprotein(a).
