GLP-1 ad war goes to court as Novo Nordisk accuses Lilly of misleading Wegovy–Zepbound ads

TL;DR Summary
Novo Nordisk filed a lawsuit alleging Eli Lilly’s GLP-1 weight‑loss ads mislead viewers by comparing Wegovy to Zepbound using Wegovy’s lower-dose data from outdated studies while ignoring Wegovy’s own high‑dose results; Lilly says the ads disclose that the high‑dose Wegovy data isn’t included and defends the head‑to‑head trial as the gold standard.
