Study of Abemaciclib and Elacestrant in Participants With Brain Metastasis Due to ER+/HER-2- Breast Cancer

This is a multi-site, global, open-label study that includes a phase 1b evaluation of elacestrant in combination with abemaciclib in women and men with brain metastases from estrogen receptor (ER)-positive, human epidermal growth factor receptor-2 (HER-2) negative breast cancer. Phase 1b was designed to select the recommended phase 2 dose (RP2D) and is followed by an ongoing phase 2 evaluation of elacestrant in combination with abemaciclib in participants with active brain metastases from ER-positive, HER-2 negative breast cancer.
