For the first time, a randomized clinical trial has shown significant tumor shrinkage with a phosphoinositide-3-kinase (PI3K) inhibitor in patients with estrogen receptor (ER)-positive, HER2-negative early breast cancer. The phase 3 study LORELEI compared neoadjuvant therapy with letrozole plus placebo versus letrozole plus taselisib, a PI3K inhibitor, in this patient population. [ Read More ]

MONARCH 3: Adding Abemaciclib to an Aromatase Inhibitor Improves Outcomes in Metastatic Breast Cancer

The addition of the cyclin-dependent kinase (CDK)4/CDK6 inhibitor abemaciclib (Verzenio) to an aromatase inhibitor improved progression-free survival (PFS) over aromatase inhibitor monotherapy in women with hormone receptor (HR)-positive, HER2-­negative advanced breast cancer, according to an interim analysis of the phase 3 MONARCH 3 clinical trial presented at the 2017 European Society for Medical Oncology (ESMO) Congress. The study was also re­cently published in the Journal of Clinical Oncology. [ Read More ]
