Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

There are several approved and guideline-recommended treatments for metastatic, estrogen receptor-positive breast cancer that has progressed on an aromatase inhibitor and a CDK4/6 inhibitor. Right now, doctors do not have a good way of choosing between these treatments. Scientists we work with have come up with ways to use the biology of the tumor to try to predict which treatment is best. This study is being done to test if those predictions are right and to learn more about these tumors to design better treatments in the future.
