Using RET inhibitors to treat breast cancer that resists hormone therapy

Official title: Repurposing RET Inhibitors for Endocrine Resistant Breast Cancer

Funded at Univ of North Carolina Chapel Hill · NIH-11086762 · Data updated 2026-11-12

This study is looking at how a protein called RET affects breast cancer that doesn't respond to hormone treatments, and it hopes to find new ways to help patients by testing a special type of medicine that targets RET.

Who could benefit from this research

Could help

Ideal candidates for this research are women with estrogen receptor-positive breast cancer who have experienced resistance to endocrine therapy.

Less likely to help

Patients with other types of breast cancer or those who have not undergone endocrine therapy may not benefit from this research.

What this research studies

This research investigates the role of RET, a receptor tyrosine kinase, in breast cancer that is resistant to endocrine therapy. The study aims to understand how high levels of RET expression contribute to treatment failure in estrogen receptor-positive breast cancer. By utilizing breast cancer organoids, researchers will explore the mechanisms behind RET's influence on therapy resistance and test the effectiveness of RET inhibitors in enhancing treatment responses. Patients may benefit from new therapeutic strategies that target RET to improve outcomes in resistant cases.

Why it matters

Potential benefit: If successful, this research could lead to more effective treatments for patients with endocrine-resistant breast cancer.

How similar studies have gone: Previous studies have shown promise in targeting RET in other cancers, suggesting potential for success in this novel application for breast cancer.
