Pfizer IncPfizer's berobenatide achieved 16% weight loss in phase 2b and plans phase 3 trials, advancing its pipeline.
Pfizer's investigational weight-loss drug berobenatide achieved nearly 16% non-placebo-adjusted weight loss in a 32-week phase 2b study with no plateau observed, positioning it as a potential competitor to Novo Nordisk's Wegovy and Eli Lilly's Zepbound. In a separate 72-week head-to-head study, Zepbound delivered 20.2% weight loss versus Wegovy's 13.7%. Berobenatide could be administered monthly, which may attract patients even if its efficacy is slightly lower than weekly alternatives, and Pfizer plans phase 3 trials across weight management and obesity-related comorbidities including obstructive sleep apnea and knee osteoarthritis. The anti-obesity market could reach $190 billion by 2035, up from $79 billion last year, according to some estimates. Pfizer acquired Metsera, the original developer of berobenatide, in November, and the stock has since moved sideways.
