Clinical Trial Summary

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.

Eligibility

Inclusion Criteria:

• Histologic diagnosis of breast cancer
• Metastatic or incurable
• Prior treatment with an anastrozole or letrozole and a CDK4/6 inhibitor
• Progression while on or within 6 months of stopping the CDK4/6 inhibitor

Related Conditions & MeSH terms

• Breast Cancer
• Breast Neoplasms
• Estrogen Receptor-positive Breast Cancer
• HER2-negative Breast Cancer

Intervention

Drug:
• Drug determined by treating oncologist based on recommendation from systems biology analysis.
All patients will have a biopsy at the beginning of the trial. The biopsy will be sent for DNA sequencing through FoundationOne(clinical test) and RNA profiling at Fulgent(research test) for determination of activation of various oncogenic pathways and phenotypes. The results will be analyzed and a treatment recommendation will be made to the treating physician based on an algorithm.
