Increased levels of unbound apo(a) which occur with muvalaplin treatment are not correlated with changes in biomarkers of cardiovascular or kidney disease. This is the main finding from a post hoc analysis of data from a Phase 2 trial of muvalaplin, an Lp(a) lowering agent in development that, in contrast to other Lp(a) targeting agents, is designed to block binding of apo(a) to apoB, thereby preventing Lp(a) formation.
