A Non-interventional Study for Kisqali Ribociclib in Combination With an Aromatase Inhibitor for Adjuvant Treatment in Patients With HRHER2- Early Breast Cancer at High Risk of Recurrence to Evaluate Real-world Effectiveness, Safety Profile, Patient Compliance and Quality of Life

What this Trial Is About

Researchers are studying the real-world effectiveness, safety, and patient experience of ribociclib combined with an aromatase inhibitor for adjuvant treatment in patients with hormone receptor-positive, HER2-negative early breast cancer at high risk of recurrence. This observational study also compares patient compliance and quality of life among those treated with ribociclib, abemaciclib with endocrine therapy, or endocrine therapy alone. The goal is to understand treatment decisions and how these therapies perform in routine care settings. Participants receive treatment as prescribed by their doctors based on local guidelines and product information for ribociclib plus aromatase inhibitor with or without LHRH, abemaciclib with endocrine therapy plus or minus LHRH, or endocrine therapy alone plus or minus LHRH. There is no random treatment assignment since this is an observational study. Baseline data are collected shortly before or after treatment initiation depending on the cohort. During the study, patients will be followed for up to 36 months to monitor invasive disease-free survival and other health outcomes. Researchers will collect information on adverse events, treatment modifications, adherence measures, quality of life questionnaires, and socio-economic factors at various timepoints. This will provide insights into treatment tolerability, patient compliance, and overall impact on quality of life in a real-world setting.
