Pfizer's Next Weight-Loss Weapon: How Berobenatide Stacks Up Against Novo Nordisk's Wegovy and Eli Lilly's Zepbound

Pfizer is developing berobenatide, a monthly injectable weight-loss drug that could compete with market leaders Novo Nordisk's Wegovy and Eli Lilly's Zepbound. Phase 2b data shows 16% weight loss in 32 weeks with no plateau, positioning it as potentially competitive despite lower efficacy than rivals. The anti-obesity market is projected to reach $190 billion by 2035, offering significant opportunity, though Pfizer faces risks from patent cliffs, increased competition from companies like Amgen, and regulatory hurdles.
