Tailoring cancer pill dosing for older adults with breast cancer
This trial is testing whether adjusting the dose of a targeted therapy (CDK 4/6 inhibitor) based on a geriatric assessment can be as effective and safer for people aged 70 and older with advanced hormone receptor-positive, HER2-negative breast cancer. It aims to find the best dose to balance benefits and side effects.
HelsinkiAges 70 years+ - NCT06171360Recruiting
Gut bacteria and CDK4/6 inhibitor treatment in breast cancer
This study looks at how gut bacteria affect response to a type of targeted therapy (CDK4/6 inhibitors) combined with hormone therapy in breast cancer that is hormone receptor-positive and HER2-negative.
