Trial Summary

What is the purpose of this trial?

This trial is testing the safety of abemaciclib when used with other treatments for patients whose breast cancer has spread. Abemaciclib helps to stop cancer cells from growing by blocking certain proteins they need. The study aims to find out if this combination is safe for patients with advanced breast cancer.

Eligibility Criteria

This trial is for adults with breast cancer that has spread, who have specific treatment histories and organ function. Participants must not have severe preexisting conditions or certain heart diseases, and should not have received some treatments like CDK4/6 inhibitors (except in Part I) or systemic chemotherapy for metastatic disease.

Inclusion Criteria

I have been treated with a nonsteroidal aromatase inhibitor for my metastatic disease and may currently be on exemestane.
My cancer progressed despite treatment with CDK4/6 inhibitors and hormone therapy.
My breast cancer is HER2 positive and has spread to other parts.

Exclusion Criteria

Have serious preexisting medical conditions that, in the judgment of the investigator, would preclude participation in this study (including interstitial lung disease (ILD), severe dyspnea at rest or requiring oxygen therapy or, history of major surgical resection involving the stomach or small bowel)
I have brain metastases treated with radiotherapy or had neurological changes within the last 14 days.
