FDA approval for Lilly’s weekly insulin Onswik, shares dip
The FDA approved Eli Lilly's (LLY) once-weekly insulin Onswik for type 2 diabetes. The drug, already approved in the EU, Mexico, and Japan, aims to reduce injections from 365 to 52 per year. Despite the approval, LLY shares dipped 1.6%. Lilly's revenue and net income have surged, reaching $22.97bn and $7.1bn respectively in Q2 2026. The company faces competition from Novo Nordisk's Awiqli in the weekly insulin market.
