Scientists hunt for genetic signs that show which breast cancer patients will benefit from kisqali

NCT ID NCT05529862

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study collects tumor and blood samples from 241 women with HR+/HER2- advanced breast cancer before and after treatment with ribociclib (Kisqali) plus hormone therapy. Researchers will analyze DNA and RNA changes to find markers that predict who responds well and who develops resistance. The goal is to better understand why some patients benefit while others relapse, and to identify new drug targets for future treatments.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

ribociclib (Kisqali) plus endocrine therapy

What this could lead to

If successful, this could help doctors predict which patients will benefit from ribociclib and endocrine therapy, and identify new treatment targets for those who don't respond.

What could go wrong

This is an observational, biomarker-focused study, not a treatment trial. It may not lead to immediate changes in patient care, and the findings might not apply to all patients.
