Novartis Shares Fall After Heart Drug Misses Target in Late-Stage Trial
Novartis shares dropped 3.2% after its experimental heart drug, pelacarsen, failed to meet its primary goal in a late-stage trial. The drug reduced Lp(a) levels but did not lower cardiovascular risk. Novartis licensed pelacarsen from Ionis Pharmaceuticals. Analysts note recent positive MS study results may offset the setback, but the company needs positive results from other drugs to justify recent acquisitions.
How this was made
The 30-second read
Why it matters
The miss undermines expectations for a first‑in‑class therapy targeting Lp(a), a high‑risk cholesterol factor, and raises questions about the commercial viability of the $12 bn Avidity acquisition.
Market read
The trial failure triggered a 3.2% share drop and may affect analyst forecasts for Novartis' 2026 earnings.
What to watch
Novartis' recent positive multiple‑sclerosis data and other pipeline assets may cushion overall earnings impact.
Background
Novartis disclosed that its antisense oligonucleotide pelacarsen failed to meet the primary cardiovascular‑outcome endpoint in a late‑stage trial, though it lowered Lp(a) levels.
Ticker impact
Novartis shares fell 3.2% in European pre‑market after its pelacarsen trial missed the primary endpoint of reducing cardiovascular events.
Short‑term downside pressure; potential 5‑8% decline over the next few days.
Clinical‑trial failures in large pharma historically trigger immediate sell‑offs, especially when the drug was a key pipeline asset.
Market effects
Biotech and cardiovascular‑drug sector may see heightened scrutiny on Lp(a) programs.
European markets could open lower on pharma weakness; US markets may follow.
Large‑cap pharma news influences global risk sentiment, especially for investors with exposure to healthcare ETFs.
Counterpoint
If the Lp(a) lowering effect still holds, the drug could be repositioned, offering a long‑term upside.
