Pfizer's monthly obesity shot, berobenatide, shows similar side effects to Wegovy, aiming for differentiation in the weight-loss market.

Detailed data from a midstage study offered further evidence that the obesity drug Pfizer acquired from the biotech Metsera could be dosed monthly.

Pfizer's berobenatide shows up to 10.2% weight loss and 2.2% blood sugar reduction in Phase 2b trial in patients with obesity and type 2 diabetes.
