What happened
Novartis and Ionis reported topline Phase III results from Lp(a)HORIZON on September 4: 8,323 patients with elevated Lp(a) and established cardiovascular disease on guideline-directed therapy. Pelacarsen lowered Lp(a) as expected. It did not reduce the composite of CV death, MI, stroke, or urgent revascularization versus placebo, in either the 70 mg/dL or the 90 mg/dL population.
What it means for practice
one trial, one population, one dose. The Lp(a) hypothesis is still alive, and the deeper-lowering programs will tell us more. For now, measuring Lp(a) still changes how you counsel residual risk, and that was always the reason to measure it.
