Eli Lilly has solidified its lead in the obesity drug market following Novo Nordisk's disappointing trial results for CagriSema, which failed to match Lilly's Zepbound in efficacy. Data indicated that CagriSema users lost only 20.2% of body weight compared to Zepbound's 25.5%, resulting in a significant 16.4% drop in Novo's stock. Concurrently, Eli Lilly shares rose nearly 4%, reflecting strong investor confidence bolstered by robust growth in their GLP-1 weight-loss portfolio.
