Finger prick could replace needle for breast cancer drug monitoring
NCT ID NCT07491380
First seen Jun 27, 2026 · Last updated Jul 24, 2026 · Updated 2 times
Summary
This study aims to see if a simple finger-prick blood test can accurately measure levels of certain breast cancer drugs (CDK4/6 inhibitors) compared to standard blood draws from a vein. About 90 breast cancer patients currently taking these drugs will provide both types of blood samples. If the finger-prick method proves reliable, it could make drug monitoring more convenient and less invasive for patients.
