HER2-positive or low breast cancer brain metastasis drug study
This Phase 2 study tests SHR-A1811 in people with HER2-positive (or HER2-low) advanced breast cancer that has spread to the brain. It aims to shrink brain tumors and control the cancer in the brain, especially when there was no need for urgent local treatment like radiation or surgery.
Zhengzhou, HenanAges 18–75 - NCT05774951RecruitingPhase 3
Camizestrant for hormone-positive, HER2-negative early breast cancer
This trial tests camizestrant, a medicine that blocks estrogen signaling, to help prevent hormone-positive, HER2-negative early breast cancer from coming back. You may be eligible if your cancer has higher- or intermediate-risk features and you already completed at least 2 years of hormone therapy.
Birmingham, AlabamaAges 18–130 - NCT05795335Recruiting
Testing CDK4/6 medicines for advanced hormone-positive breast cancer
This trial studies how CDK4/6 medicines fit into treatment for people with advanced hormone receptor–positive breast cancer that cannot be cured with surgery or radiation. It may help doctors understand the best way to use these medicines for disease that has returned or spread.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05806060RecruitingPhase 3
Targeted first treatment for a rare TNBC subtype with spread
This Phase 3 trial tests a more precise treatment strategy for a specific rare type of triple-negative breast cancer (TNBC) called the BLIS subtype. It’s for people whose cancer has spread or cannot be fully removed and who have not had chemo or targeted therapy for metastatic TNBC yet.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05851014RecruitingPhase 3
GB491 plus letrozole for HR+ HER2- advanced breast cancer
This Phase 3 study tests whether GB491 used together with letrozole works better for hormone receptor–positive and HER2-negative advanced breast cancer. You may be eligible if you have not had certain prior cancer treatments and your health tests are within safe limits.
Bengbu, AnhuiAges 18–75 - NCT05860465RecruitingPhase 2/Phase 3
Tested blood cancer medicine with hormone therapy for breast cancer
This trial studies SPH4336 given together with standard hormone (endocrine) therapy for breast cancer that has spread or cannot be treated with surgery. It aims to see whether the combination is safer and more effective than hormone therapy alone.
