Novartis DM1 drug fails late-stage trial, clouding development outlook
Novartis's experimental drug delpacibart etedesiran (del-desiran) for myotonic dystrophy type 1 failed to meet the main goal in a late-stage trial, missing statistical significance on the primary endpoint. The study showed some clinical activity in other measures, and safety findings were consistent with prior data. Novartis will evaluate the full dataset and consult health authorities to determine next steps. The company maintains its 5-6% sales CAGR guidance for 2025-2030.
