A high dose of Novo Nordisk’s obesity drug Wegovy led patients to lose substantial weight in a clinical trial, but still less than what’s been seen with Zepbound.

Wegovy, the weight-loss brand of semaglutide, has a recommended maintenance dose of 2.4 mg. Novo ran the Phase III STEP UP trial to evaluate the effect of increasing the maximum dose to 7.2 mg. The trial randomized 1,407 adults with obesity, but not diabetes, to receive either 7.2 mg or 2.4 mg of semaglutide or placebo.

Novo Nordisk said patients taking a bigger dose of its blockbuster obesity drug lost more weight than those on a lower dose, without experiencing an increase in side effects.
