U.S. FDA approves Inluriyo (imlunestrant) in combination with Verzenio (abemaciclib) for adults with ER+, HER2-, ESR1-mutated advanced or metastatic breast cancer
Eli Lilly's Inluriyo (imlunestrant) received FDA approval in combination with Verzenio (abemaciclib) for ER+, HER2-, ESR1-mutated advanced/metastatic breast cancer. The approval follows Phase 3 EMBER-3 trial results showing the combination doubled median progression-free survival (11.1 months vs. 5.5 months) compared to Inluriyo alone. The treatment targets two key drivers of breast cancer growth, offering a new option for patients with disease progression.
