Eli Lilly's orforglipron demonstrates significant advantages over Novo Nordisk's Rybelsus, achieving superior weight loss and better A1C reduction in recent trials. As Eli Lilly showcases strong sales of $14.7 billion in the first half of 2025 and continues to expand its portfolio, Novo Nordisk grapples with a 28.1% share decline and a revised outlook. The competition intensifies in the lucrative GLP-1 market, compounded by high-stakes developments such as Novo's cardiovascular approval for Rybelsus.
