Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients diagnosed with HR+/HER2- early breast cancer who are at high risk of recurrence and are eligible for treatment with ribociclib and an aromatase inhibitor.

Probably not a fit

Patients with HR-/HER2+ breast cancer or those not indicated for ribociclib treatment may not benefit from this study.

What this trial studies

This observational study assesses the real-world effectiveness and safety of ribociclib combined with an aromatase inhibitor for patients with HR+/HER2- early breast cancer who are at high risk of recurrence. It aims to gather data on patient compliance, quality of life, and management of adverse events. The study will also compare outcomes with patients receiving other treatment regimens, including abemaciclib and endocrine therapy. Conducted across various breast centers in Germany, it seeks to provide insights into the clinical adoption of ribociclib after its EU approval.

Why it matters

Potential benefit: If successful, this study could enhance treatment strategies for patients with high-risk early breast cancer, potentially improving their outcomes.

How similar studies have gone: Other studies have shown promise with similar treatment approaches, but this specific combination is being evaluated in a real-world setting.
