DublinAges 18 years+ - NCT06813456Recruiting
Improving HER2 detection in breast cancer with new testing method
This trial studies a more precise way to measure HER2 levels in breast cancer tissue. It may help identify patients whose cancer is HER2-low or HER2-zero, so they can get more targeted treatment.
Bologna, BolognaAges 18 years+ - NCT05525767RecruitingPhase 4
Bevacizumab plus chemo before surgery for HER2-negative breast cancer
This trial studies whether adding bevacizumab (an anti-blood-vessel medicine) to chemotherapy before surgery improves treatment outcomes for people with HER2-negative breast cancer. It’s mainly for tumors that are stage II to IIIC and have not had prior cancer treatment.
Shijiazhuang, HebeiAges 18 years+ - NCT06462092RecruitingPhase 1/Phase 2
Sacituzumab Govitecan and Spinal Chemo for Breast Cancer Spread to Spinal Fluid
This trial tests a combination of a targeted antibody-drug (sacituzumab govitecan) and chemotherapy given into the spinal fluid. It is for people with HER2-negative breast cancer that has spread to the membranes around the brain and spinal cord (leptomeningeal metastases). The goal is to see if this treatment can help control the cancer in the central nervous system.
Huizhou, GuangdongAges 18–75 - NCT06839001RecruitingPhase 3
Freezing small breast tumors instead of surgery trial
This study tests if freezing a very small early-stage breast tumor (cryoablation) can be as effective as surgery. It may be an option for people whose tumor is small enough and hasn't spread to lymph nodes or elsewhere.
