Recruiting studies
- NCT06065748RecruitingPhase 3
New hormone therapy for advanced breast cancer after prior treatment
This trial tests a new oral hormone therapy, giredestrant, against a standard hormone therapy (fulvestrant) when both are given with a CDK4/6 inhibitor. It is for people with advanced ER-positive, HER2-negative breast cancer that has come back after initial hormone therapy, and who have not yet had other treatments for advanced disease.

Beijing, Beijing MunicipalityAges Any age - NCT07112053RecruitingPhase 2
Vaccine with hormone therapy or chemo for advanced breast cancer
This trial tests a vaccine (STEMVAC) given with your standard hormone therapy or chemotherapy. It is for people with advanced hormone receptor-positive, HER2-negative breast cancer who are already on certain treatments. The goal is to see if adding the vaccine can help control the cancer better.
Seattle, WashingtonAges 18 years+ - NCT05831878Recruiting
Drug RC48 for HER2-low or HER2-ultralow breast cancer
This trial tests RC48, an antibody-drug treatment, for people with advanced breast cancer that cannot be cured or removed, specifically HER2-low (or HER2-ultralow) tumors. It may help by targeting cancer cells with this “HER2-low” trait while limiting spread in the body.
ShanghaiAges 18 years+ - NCT07586215Recruiting
HER2-targeted PET imaging to predict treatment response in advanced breast cancer

ShanghaiAges 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+ - NCT06458413RecruitingPhase 2
Utidelone plus capecitabine for metastatic breast cancer
This trial tests a combination of two chemotherapy drugs, utidelone and capecitabine, for women with HER2-negative breast cancer that has spread to other parts of the body. The goal is to see if this combination can help shrink tumors and slow the cancer's growth.
Zhengzhou, HenanAges 18–70 - NCT07180160RecruitingPhase 2
A study of QL1706 for HR-positive, HER2-negative breast cancer
This trial tests a new drug combination (iparomlimab and tuvonralimab, also called QL1706) for people with advanced breast cancer that is hormone receptor-positive and HER2-negative. It may be an option if standard treatments have stopped working.
ShanghaiAges 18 years+ - NCT06856200Recruiting
Sirolimus plus palbociclib and fulvestrant for advanced breast cancer
This trial tests a new combination of three drugs (sirolimus, palbociclib, and fulvestrant) for people with a certain type of advanced breast cancer that is hormone receptor-positive and HER2-negative. The goal is to see if adding sirolimus can help control the cancer when standard hormone therapy is no longer working.
ShanghaiAges 18 years+ - NCT05467891RecruitingPhase 2
Ribociclib plus hormone therapy for recurrent breast cancer
This trial tests whether adding ribociclib (a targeted pill) to hormone therapy can control breast cancer that has come back in the breast area or nearby lymph nodes/chest wall. It targets hormone-receptor–positive and HER2-negative tumors to help slow disease after local treatment.
Birmingham, AlabamaAges 18 years+ - NCT04547907RecruitingPhase 3
