VillejuifAges 18 years+ - NCT06435429RecruitingPhase 3
Zanidatamab vs trastuzumab for HER2+ breast cancer
This study compares a new drug called zanidatamab against trastuzumab (Herceptin), both given with a chemotherapy of your doctor's choice. It is for people with HER2-positive breast cancer that has spread and who have already tried T-DXd treatment.
Phoenix, ArizonaAges 18 years+ - NCT07136428RecruitingPhase 1/Phase 2
Asciminib for HER2+ breast cancer that has spread to the brain
This trial tests the drug asciminib for people with HER2-positive breast cancer that has spread to the brain and is growing. It may be an option if you have already tried standard treatments like T-DXd and tucatinib.
Durham, North CarolinaAges 18 years+ - NCT06171360Recruiting
Gut bacteria and CDK4/6 inhibitor treatment in breast cancer
This study looks at how gut bacteria affect response to a type of targeted therapy (CDK4/6 inhibitors) combined with hormone therapy in breast cancer that is hormone receptor-positive and HER2-negative. It may help find out why some people respond better to treatment and could lead to better personalized care.
BrusselsAges 18–100 - NCT07233499RecruitingPhase 2
Nebivolol for heart protection during breast cancer treatment
This trial tests if the drug nebivolol can protect the heart from damage caused by trastuzumab (Herceptin) in women with HER2-positive breast cancer. If effective, it may help prevent heart problems while still allowing cancer treatment.
CairoAges 18–65 - NCT05978648RecruitingPhase 2
Trilaciclib for early-stage HR-negative breast cancer after surgery
This trial tests if adding trilaciclib to standard chemotherapy after surgery can help people with hormone receptor-negative breast cancer. It aims to reduce side effects and improve treatment outcomes.
Guangzhou, GangdongAges 18 years+ - NCT07243002Recruiting
Patient outcomes with ribociclib or abemaciclib for early breast cancer
This study looks at how women and men with stage II or III HR+ HER2- breast cancer do when they start treatment with ribociclib or abemaciclib (combined with hormone therapy) after surgery. Researchers want to understand real-world experiences and results.
