Official title
Treatment Landscape and Real-World Dosing Patterns With CDK4/6 Inhibitors for HR+/HER2- Advanced/Metastatic Breast Cancer in Portugal
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Assess and characterize the real-world cyclin-dependent kinase 4/6 inhibitor (CDKI) use in advanced/metastatic breast cancer (a/mBC), evaluate treatment persistence, and quantify CDKI dose adjustments in Portugal. This study used secondary data from the IQVIA database that collects data from hospital drug consumption. The study included 16 public hospitals across Portugal, for which data on consumption of drugs used in hormone receptor positive/human epidermal growth factor receptor 2 negative (HR+/HER2-) a/mBC treatment was available. Patient selection was based on a set of criteria considering all patients with treatments in the a/mBC setting with use of at least one CDKI from November 2018 to May 2023.
