TaipeiAges 20 years+ - NCT05181033RecruitingPhase 2
Lenvatinib plus letrozole versus fulvestrant for metastatic breast cancer
This Phase 2 study compares a combination medicine (lenvatinib plus letrozole) against fulvestrant to treat metastatic estrogen-receptor positive, HER2-negative breast cancer after the cancer has grown despite hormone therapy plus a CDK4/6 inhibitor. It may help by finding a more effective treatment option after your first lines have stopped working.
SingaporeAges 18–99 - NCT05933395RecruitingPhase 2
Targeted treatment for ER+ breast cancer after CDK4/6 therapy
This Phase 2 study tests a genetically guided treatment plan for ER-positive breast cancer that has progressed after CDK4/6 therapy. It may help by matching treatment to tumor genetic changes.
Lebanon, New HampshireAges 18 years+ - NCT06230055RecruitingPhase 4
Chemotherapy for breast cancer that has spread to the spinal fluid
This trial tests a chemotherapy drug given directly into the spinal fluid for people with HER2-negative breast cancer that has spread to the lining of the brain and spinal cord (called leptomeningeal metastasis). It may help when standard treatments have stopped working or caused too many side effects.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05856773RecruitingPhase 3
Standard vs shorter radiation to lymph nodes for breast cancer
This trial compares two ways of giving radiation to the breast/chest wall and nearby lymph nodes after breast surgery: a standard schedule versus a shorter “hypofractionated” schedule. It uses proton therapy and may help reduce treatment time while still controlling the cancer.
Scottsdale, ArizonaAges 19 years+ - NCT06374745Recruiting
A surgery plan for chronic lymphedema after breast cancer
This trial looks at a combined approach to treat chronic lymphedema (long-term arm swelling) after breast cancer treatment. Doctors will use different surgical techniques, alone or together, to see which works best.
BaselAges Any age - NCT06551220Recruiting
T-DXd for advanced breast cancer with various HER2 levels
This study looks at how well the drug T-DXd (Enhertu) works against breast cancer that has spread or can't be removed with surgery. It includes patients with any level of HER2 protein, so it might be an option even if your cancer has low HER2.
New Haven, ConnecticutAges 18–80 - NCT06927895Recruiting
Education program for HER2 breast cancer patients
This study is testing whether an educational program helps people with HER2 breast cancer learn more about their treatment and manage side effects. Participants will have virtual visits and watch online training videos.
New York, New YorkAges 18 years+ - NCT07092111Recruiting
Ear acupuncture to prevent nerve damage from chemotherapy in breast cancer
This trial tests if ear acupuncture can help prevent nerve damage caused by taxane chemotherapy in breast cancer patients. If you are starting 4 rounds of this chemo and have not had nerve issues before, this may be an option for you.
Nanjing, JiangsuAges 18–75 - NCT07262138Recruiting
Active monitoring for older women with early breast cancer
This trial studies whether active monitoring (watchful waiting) can be a safe option instead of immediate surgery or other treatments for women 70 and older who have a small, slow-growing type of breast cancer. If you join, you will not have surgery or other treatments right away, but your cancer will be closely watched.
Pittsburgh, PennsylvaniaAges 70 years+ - NCT07400523RecruitingPhase 3
Ribociclib for breast cancer with leftover disease after chemo
This trial tests ribociclib, a targeted therapy, for women with hormone receptor-positive, HER2-negative breast cancer who still have cancer cells in the breast or lymph nodes after initial chemotherapy. It aims to reduce the chance of cancer coming back.
Zhanjiang, GuangdongAges 18 years+ - NCT07292571Enrolling by invitationPhase 2
Tracing breast cancer HER2 with a special scan
This study uses a radioactive tracer to see how much HER2 protein is on your breast cancer cells. The scan may help doctors understand the type of HER2 you have and choose the best treatment.
TomskAges 18–80 - NCT06943313Enrolling by invitation
Breast cancer PET/CT imaging with a new tracer
This trial tests a new imaging agent (68Ga-pAKTi) that may help doctors see breast cancer cells with a PET/CT scan. It is for people with a specific genetic change in their tumor, and who have not yet had surgery to remove the cancer.
ShanghaiAges 18 years+ - NCT05879926RecruitingPhase 3
Testing chemo after hormone therapy in premenopausal early breast cancer
This Phase 3 trial checks whether adding chemotherapy after standard hormone-blocking treatment works better for some premenopausal women with early-stage, ER-positive, HER2-negative breast cancer. It targets patients with limited lymph node spread and a lower-to-intermediate tumor “recurrence” risk score.
Birmingham, AlabamaAges 18–60 - NCT05400941Enrolling by invitation
Breast cancer follow-up support in primary care
This study looks at how breast cancer follow-up care can be better done in primary care clinics. It may help by improving care check-ins and support for people who have had breast cancer and for clinic staff involved in that care.
New Brunswick, New JerseyAges 21 years+ - NCT06195306RecruitingPhase 2
Low dose tamoxifen and omega-3 for breast cancer prevention
This study tests whether low-dose tamoxifen (a breast cancer prevention drug) or omega-3 supplements can lower breast cancer risk in postmenopausal women who are overweight and have a higher chance of getting the disease. The study lasts about 6 months and involves blood draws and a breast fluid test to see how the treatment affects breast cells.
Kansas City, KansasAges 45–74 - NCT06998108RecruitingPhase 3
A new drug with fulvestrant for HR+/HER2- advanced breast cancer
This trial tests a new investigational drug called BEBT-209 combined with fulvestrant (a hormone therapy) versus placebo with fulvestrant for people with a type of breast cancer that is hormone receptor-positive and HER2-negative. It is for those whose cancer has worsened after previous hormone therapy and has spread locally or to other parts of the body.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07365267Recruiting
3D printed mesh for breast reconstruction after mastectomy
This trial tests a new 3D printed biodegradable mesh used during breast reconstruction right after a mastectomy for breast cancer. It aims to see how well the mesh works for cosmetic results and safety.
Xi'an, ShaanxiAges 18–70 - NCT06451497RecruitingPhase 1
Testing ZM008 alone and with toripalimab for advanced cancers
