The BareStory
Shares of Danish pharmaceutical company Novo Nordisk fell more than 16% on Monday after Phase 3 trial results for its next-generation weight loss drug, CagriSema, failed to outperform a key competitor. Data showed that CagriSema resulted in 23% weight loss over 84 weeks, compared to approximately 25% for Eli Lilly’s Zepbound in the same study. While Novo Nordisk Chief Scientific Officer Martin Holst Lange described the effect as "clinically meaningful," analysts expressed concern regarding the drug’s potential to gain market share against the established leader.
Novo Nordisk CEO Mike Doustdar defended the product, characterizing the competitor's higher performance in the trial as an "abnormality." Despite the comparative shortfall, the company has filed for U.S. FDA approval for CagriSema, with a decision anticipated in late 2026. Doustdar also noted that future trials would investigate the efficacy of higher doses.
The clinical setback coincides with significant financial headwinds for the drugmaker. Novo Nordisk recently forecast that sales and profits would decline by 5% to 13% in 2026, marking its first expected annual sales drop since 2017. The company faces intensifying competition from Eli Lilly, whose market share in the GLP-1 weight loss sector is estimated at 60%, compared to Novo’s 40%. Additionally, Novo’s stock has declined 75% from its mid-2024 peak.
To counter these challenges, executives pointed to a pipeline that includes a pill version of the drug Wegovy and plans for active dealmaking. Last year, the company paid $2 billion for rights to an experimental medicine similar to a treatment under development by Eli Lilly. Doustdar acknowledged current pricing pressures—including recent agreements to lower costs for U.S. government programs—but stated that new medicines and increased volumes are expected to drive long-term growth.
How it may affect me
As a U.S. reader:
You may have access to a new weight loss drug option called CagriSema by late 2026, though current trial data indicates it results in slightly less weight loss than the competitor Zepbound.
Ongoing competition and recent agreements to lower costs for government programs may result in reduced pricing for weight loss treatments as manufacturers shift strategies to prioritize sales volume over high profit margins.
Future treatment options could become more diverse and convenient, as companies invest in developing pill versions of drugs like Wegovy and acquiring rights to other experimental medicines to remain competitive.
