What this trial studies

This study aims to assess the effectiveness, safety, and quality of life of older patients (aged 65 and above) with HR+HER2- advanced breast cancer who are receiving ribociclib in combination with endocrine therapy in real-world clinical settings in Russia. It involves a prospective, non-interventional design where patients will be followed for 24 months after starting treatment. The study will collect primary data through routine clinical visits, which are expected to occur every 3-4 months, and interim analyses will be conducted after enrollment and one year later.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness and safety of ribociclib combined with endocrine therapy for elderly patients with advanced breast cancer.

How similar studies have gone: While this study focuses on a specific demographic and treatment combination, similar approaches in evaluating ribociclib have shown promise in other populations, suggesting potential for success.
