Comparing Oral Drug Dosing Strategies in Older Patients With Metastatic Breast Cancer to Maximize Tolerance and Reduce Discontinuation: The CDK4/6 Inhibitor Dosing Knowledge (CDK) Study

Low burden on patient

The trial has a low burden on patients. An example would be a trial testing an oral drug, with scans every 12 weeks which would be similar to standard of care.

The goal is to determine which dosing approach better maximizes medication tolerance and reduces early discontinuation in this older population.
