Pfizer’s Berobenatide Shows Nearly 16% Weight Loss vs Wegovy and Zepbound
In a phase 2b study, Pfizer’s berobenatide delivered nearly 16% weight loss over 32 weeks without a plateau. The result compares with head-to-head outcomes for Eli Lilly’s Zepbound (20.2% over 72 weeks) and Novo Nordisk’s Wegovy (13.7%). Confirming these effects in phase 3 could position it as a major anti-obesity drug.
