Forget Eli Lilly and Novo: This Biotech Could Be a Surprising Winner in the Weight Loss Market

Regeneron Pharmaceuticals (NASDAQ:REGN) is positioning itself as a contender in the weight loss market with two promising drugs: olatorepatide, which showed 19% weight loss in trials, and trevogrumab, which helps preserve lean mass. Regeneron's revenue grew 17% YoY to $4.3B in Q2, driven by Dupixent's 38% YoY sales increase to $6B. Eylea HD sales rose 52% YoY to $596M, mitigating declines in the original Eylea.
