Predicting lymph node spread in breast cancer
This study looks at whether substances called metabolites in your blood and breast tissue can help predict if breast cancer has spread to the first lymph node (sentinel node).

This early-phase trial tests a combination of two targeted drugs, neratinib and ruxolitinib, for people with metastatic triple-negative breast cancer who have already had standard chemotherapy. The goal is to see if the combination is safe and effective.
Dallas, TexasAges 18 years+ - NCT06016387RecruitingPhase 2
Drug combo with radiation for HER2+ breast cancer spread to spinal lining
This trial tests a combination of three targeted drugs (tucatinib, trastuzumab, and capecitabine) along with radiation to the brain or spine for people whose HER2-positive breast cancer has spread to the lining of the brain or spinal cord. The goal is to see if this treatment is safe and effective.

Study of two drugs for advanced HER2-negative breast cancer
This trial tests two experimental drugs, SI-B003 and BL-B01D1 plus SI-B003, for people with HER2-negative breast cancer that has spread or cannot be removed by surgery. It is for those who have tried standard treatments or cannot have them.
