A Non-interventional Study for Women With HR-positive, HER2-negative Locally Advanced or Metastatic Breast Cancer to Evaluate the Real-world Effectiveness of Treatment Algorithms Beginning With Kisqali (Ribociclib) in Combination With an Aromatase Inhibitor/Fulvestrant, or With Endocrine Therapy or Chemotherapy as First Line Treatment

This non-interventional study collects data from clinical practice capturing on effectiveness, safety and tolerability, duration of therapy, and quality of life of ribociclib in combination with an aromatase inhibitor/fulvestrant in daily routine and in line with the respective current German summary of product characteristics. In order to put these results into perspective, data is also collected on patients treated with endocrine therapy or chemotherapy for first line locally advanced or metastatic breast cancer. To gain insight into algorithms and outcome of sequential therapy, up to three lines of treatment are documented within this study. The information gathered and evaluated in this NIS is helping to answer open questions for the treatment of locally advanced/metastatic breast cancer and provides first insights into the treatment reality with ribociclib in this setting. This includes, but is not limited to, the questions on baseline demographics leading to a specific treatment decision, as well as efficacy and clinical routine related to treatment sequencing. In addition, data on the mutation status (including PIK3CA and BRCA1/2) is collected at different time points to generate insights into the clinical routine of mutation testing and to understand its impact on therapy sequencing.
