Eli Lilly said on Sunday its drug Zepbound was superior to Novo Nordisk's Wegovy across five weight-loss targets such as reducing waist circumference, citing data from a head-to-head trial.

Eli Lilly’s (LLY) and Novo Nordisk’s (NVO) weight loss drugs went head-to-head in a weight loss study for the first time — and Eli Lilly’s drug came out on top.

A new study has found that people taking Eli Lilly's obesity drug Zepbound lost almost 50% more weight than those using Novo Nordisk's Wegovy.
