Muvalaplin is an investigational new drug that is being evaluated in clinical trials for the treatment of cardiovascular disease associated with elevated lipoprotein(a) levels.^[1]^[2] It is an orally bioavailable small molecule drug that blocks the initial interaction between apolipoprotein(a) and apoB100, thereby preventing the assembly of new lipoprotein(a) particles without interfering with plasminogen function. Large-scale studies are underway to assess muvalaplin’s safety and efficacy for reducing cardiovascular risk in people with high levels of lipoprotein(a).^[1]

Chemistry

Muvalaplin is a synthetic trivalent small molecule built around a central tribenzylamine scaffold. Attached to this core are three identical arms, each consisting of a (S)-2-[(3R)-pyrrolidin-3-yl]propanoic acid moiety. The molecule’s tripodal configuration enables simultaneous engagement of multiple lysine-binding sites on the apo(a) kringle domains, which is essential for potent inhibition of lipoprotein(a) assembly.^[3]
