FDA Approves Efsitora Once-Weekly Basal Insulin Injection
The FDA approved Eli Lilly's once-weekly basal insulin drug, Efsitora, for adults with type 2 diabetes. The drug is designed to reduce injections by over 300 per year. Efsitora will be available in prefilled pens with two concentrations. The approval was supported by phase 3 clinical trials showing noninferiority to once-daily insulin. Efsitora is the second long-acting, once-weekly insulin approved by the FDA, following Novo Nordisk's Awiqli.
