GLP-1 drug Zepbound leads to greater weight and waist loss than Wegovy in 72-week trial, say researchers at European Congress on Obesity comparing new-generation weight-loss drugs

In addition to eliciting greater weight loss than Novo Nordisk’s Wegovy, Eli Lilly’s Zepbound does not come at the expense of safety, according to newly released comprehensive tolerability data—findings that Leerink analysts say confirm the GLP-1 drug’s edge in the closely watched market race.

The first clinical trial comparing semaglutide and tirzepatide, two popular, injectable weight-loss drugs, has been published, examining their ability to reduce weight and waist circumference. And one clearly comes out on top.
