Summary

This study tests a drug called alisertib combined with hormone therapy for people with a common type of advanced breast cancer (HR+, HER2-). The cancer has continued to grow despite at least two prior hormone treatments. The goal is to find the best dose of alisertib and see if the combination can shrink tumors or slow the disease. About 150 adults will take part in this phase 2 trial.

HR and HER2 testing must be performed consistent with current American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) or European Society of Medical Oncology (ESMO) guidelines. Exclusion Criteria: * Treatment with chemotherapy in the recurrent or metastatic setting, including antibody drug conjugates with a chemotherapeutic payload. * Prior treatment with an Aurora Kinase A (AURKA) specific-targeted or pan-Aurora-targeted agent, including alisertib, in any setting.
