The MONARCH 3 trial led to abemaciclib plus nonsteroidal aromatase inhibitor approval as initial therapy in postmenopausal patients with hormone receptor-positive (HR+), and human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer with significant improvement in progression-free survival. Prof. Matthew Goetz (Mayo Clinic, Rochester, MN, USA) joins touchONCOLOGY to discuss what the MONARCH 3 study teach us about the efficacy and safety of abemaciclib plus NSAI in patients with HR+, HER2- advanced breast cancer, the clinical impacts of the availability of abemaciclib, and the results of the interim overall survival analysis.
The abstract entitled ‘MONARCH 3: Interim overall survival (OS) results of abemaciclib plus a nonsteroidal aromatase inhibitor (NSAI) in patients (pts) with HR+, HER2- advanced breast cancer (ABC)‘ Abstract LBA5, was presented at European Society for Medical Oncology (ESMO) 2022.
