Novartis AGLate-stage pelacarsen study failed to meet primary endpoint, causing stock drop.
Novartis announced that its late-stage cardiovascular outcomes study of pelacarsen, an investigational antisense oligonucleotide designed to inhibit lipoprotein(a) production, failed to meet its primary endpoint. The Lp(a)HORIZON trial, which enrolled 8,323 patients with elevated Lp(a) and established cardiovascular disease, did not show a significant reduction in major adverse cardiovascular events compared to placebo. Shares of Novartis fell 4.7% in after-hours trading, while Ionis Pharmaceuticals, which discovered pelacarsen and licensed global rights to Novartis, dropped 10%. Amgen also saw a 5% decline in after-hours trading on September 4, as investors worried about the prospects of its similar drug olpasiran. Despite the setback, Novartis continues to rely on growth products like Kisqali and Kesimpta to offset generic competition for Entresto, with 2026 expected to be its largest patent cliff.
