Novartis rocked the stock market after a series of clinical failures

The stock price of pharmaceutical giant Novartis dropped by nearly 9% on Tuesday after another clinical trial failure involving its ongoing treatments. The company announced that Del-Desiran, a treatment for Duchenne muscular dystrophy type 1 (DM1), did not meet its primary endpoints in a Phase III study. This setback follows a previous failure with pelacarsen, a cardiovascular treatment, which had already caused the stock to decline earlier in the week. The Wall Street Journal reported that Novartis temporarily paused experimental CAR-T cell therapy trials for autoimmune and neurological diseases after three patient deaths. Analysts described the latest results as a 'major setback' for the company, with some warning of increased risk for future treatments like Del-Brax. Despite these challenges, Novartis reaffirmed its growth targets for 2025–2030.

Novartis shares plunged over 10 percent in early trading on Tuesday, marking the largest drop since 2020. The Swiss pharmaceutical giant’s stock fell sharply after disappointing study results for a drug aimed at treating a muscle disease. This follows another setback just days earlier, when a heart medication failed to meet its primary goal in trials. The decline dragged down the Swiss Market Index (SMI), which lost 1.4 percent in early trade. The latest blow came from the Harbor Study, which tested the drug Del-desiran for myotonic dystrophy type 1, a progressive muscle disorder. Around 150 patients were monitored over 54 weeks, with the main focus on how quickly they could open their hands, a measure of muscle stiffness. While some secondary indicators suggested possible effects, the drug did not achieve the desired outcome. This marks the second major clinical trial failure for Novartis within a few days, following the unsuccessful test of Pelacarsen, a heart medication, which led to a 3.2 percent share loss on Monday. The sharp decline erased much of the gains made last week, when Novartis shares hit a new all-time high. Despite this recent success, the current losses have wiped out significant portions of the year-to-date gains. As of early Tuesday, the stock was trading at 113.42 francs, down nearly 15 percent from its previous peak of 132.68 francs. Analysts warn that the setbacks have shaken investor confidence. The Zurich Cantonal Bank noted a loss of trust in Novartis' pipeline of drugs acquired through its acquisition of US biotech firm Avidity Biosciences. Although other candidates from the deal showed promising results, the recent failures have raised concerns. Vontobel described the study result as a clear setback, while UBS also expressed disappointment, revising its expectations for the drug's potential revenue. Last week, Novartis celebrated record-breaking performance with positive trial data for a multiple sclerosis treatment, pushing its stock to a new high. However, the current slump has left investors wary. With the company already facing challenges from the failed heart medication, the latest results have added to the uncertainty surrounding its future prospects.

Novartis crashes after drug trial backfires

Novartis shares fell sharply after a failed clinical trial for a drug candidate targeting muscle disease. The stock dropped over 10% in early trading following disappointing results from the Harbor study testing Del-desiran for myotonic dystrophy type 1. Analysts expressed concern about investor confidence, particularly regarding drugs acquired through the purchase of Avidity Biosciences, despite other promising candidates from that acquisition. While the primary goal of improving hand movement speed was not met, Novartis noted some indications of efficacy in secondary measures. This marks the second setback for Novartis in days, following earlier disappointing results for another drug, Pelacarsen.
