NCT ID NCT07574749
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study is testing a new blood-based diagnostic that looks at tiny particles from breast cancer cells to determine the cancer's molecular subtype. Researchers will compare results from this test with standard tissue biopsies in 1,500 people with advanced breast cancer. If accurate, the test could offer a quicker, less invasive way to guide treatment decisions.
