Novartis Pharma AG: Novartis announces Lp(a)HORIZON Phase III topline results for pelacarsen in patients with elevated Lp(a) and established cardiovascular disease (CVD)

Novartis announced that the Phase III Lp(a)HORIZON trial for pelacarsen did not meet its primary endpoint of reducing cardiovascular events. The study, involving 8,323 patients, showed that while pelacarsen lowered Lp(a) levels, it did not reduce cardiovascular risk. Novartis obtained rights to pelacarsen from Ionis Pharmaceuticals. Elevated Lp(a) affects about 20% of people worldwide and has no approved targeted treatment.
