New combo therapy aims to control advanced breast cancer
NCT ID NCT06369285
First seen Jun 27, 2026 · Last updated Jul 28, 2026 · Updated 2 times
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.

Inclusion Criteria: * Aged ≥18 years at signing of informed consent. * Pathology-confirmed diagnosis of breast cancer with evidence of recurrent or metastatic disease not amenable to curative therapy. * Progression on or after treatment with at least two prior lines of endocrine therapy in the recurrent or metastatic setting. a. If metastatic disease recurrence occurs during or within six months of discontinuing adjuvant endocrine therapy, then that endocrine therapy will count as one line of prior therapy. * Participants must have received a CDK4/6i in combination with endocrine therapy in the recurrent or metastatic setting. * HR-positive and HER2-negative tumor status reported per local laboratory testing. 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. Note: There are additional inclusion and exclusion criteria. The study center will determine if you meet all of the criteria.
