Novo Nordisk sued rival Eli Lilly in a U.S. federal court on Tuesday, accusing the U.S. drugmaker of false advertising in claiming its weight-loss medicines outperform Novo's drugs.
The Danish company filed the lawsuit in U.S. District Court in New Jersey, alleging Lilly violated federal and state false advertising and unfair competition laws, including the Lanham Act, through nationwide advertising campaigns for obesity drug Zepbound and diabetes treatment Mounjaro.
