Novo Nordisk's CagriSema obesity drug demonstrated comparable safety and efficacy to Eli Lilly's Zepbound in late-stage trials, with patients experiencing approximately 20% weight loss over 68 weeks. However, full results indicate that the rate of weight loss plateaued at the end of the trial, tempering investor expectations regarding CagriSema's potential as a superior treatment option. Novo Nordisk plans a longer study to assess the drug's ability to induce further weight loss beyond the initial 68-week period.
Late-stage Phase 3 trial results for Novo Nordisk's obesity candidate, CagriSema, indicate its efficacy and safety profile is comparable to Eli Lilly's competing drug, Zepbound. The data shows a 20% weight loss over 68 weeks, a level similar to that observed in Zepbound studies, which tempers investor expectations that CagriSema would be a superior, market-differentiating treatment. Critically, newly released full results reveal that the rate of weight loss began to plateau towards the end of the 68-week period. This plateau raises significant doubts about the drug's potential for continued efficacy in longer-term treatments, directly challenging the investment thesis that relied on CagriSema demonstrating standout performance. While Novo Nordisk plans a longer study, the current data suggests the drug may not unseat Zepbound as a market leader, but rather will enter the market as a peer competitor.
