NCT ID NCT06452394
First seen Jan 09, 2026 · Last updated May 16, 2026 · Updated 17 times
Summary
This study tests whether adding doxycycline, a cheap and safe antibiotic, to standard chemotherapy can better target cancer stem cells in early-stage breast cancer. These stem cells are thought to resist treatment and cause cancer to return. About 50 women with ER+/HER2- breast cancer will receive doxycycline alongside chemo before surgery, and researchers will check if it reduces the number of these resistant cells.
