FDA requires vision-loss warning on Novo Nordisk and Eli Lilly GLP-1 drugs
The FDA will require Novo Nordisk (NYSE:NVO) and Eli Lilly (NYSE:LLY) to add a warning about a rare eye condition to their GLP-1 drugs. The FDA's decision follows a review of clinical trials and adverse event reports. The drugs showed a higher incidence of NAION compared to placebos and other diabetes treatments. Both companies face lawsuits related to vision impairment. The FDA's decision may impact investor sentiment toward these high-margin obesity drugs.
