Novo Nordisk A/SCagriSema missed non-inferiority vs Zepbound, and sales growth is weak, widening gap with Lilly.
Novo Nordisk is counting on its next-generation obesity drug CagriSema to close the competitive gap with Eli Lilly, having filed for U.S. approval with an FDA decision expected in the fourth quarter of 2026. In the phase III REDEFINE 1 study, CagriSema achieved a mean weight loss of 22.7% after 68 weeks, compared with 16.1% for Wegovy, but in the head-to-head REDEFINE 4 trial it delivered 23% weight loss versus Zepbound's 25.5%, failing to show non-inferiority. The company's need for new growth drivers is pressing as first-half 2026 adjusted sales rose only 2% at constant exchange rates, while Eli Lilly's Mounjaro and Zepbound generated $18.6 billion and $9.1 billion in first-half sales, up 106% and 60% respectively. Novo Nordisk is also testing a higher-dose combination of cagrilintide 2.4 mg with Wegovy HD (semaglutide 7.2 mg) in a phase III study planned for the second half of 2026, and results from the REDEFINE 11 study are expected in the first half of 2027. The company faces additional competition from Viking Therapeutics and Structure Therapeutics, which are advancing their own GLP-1-based obesity therapies.
