Sarasota, FloridaAges 12 years+ - NCT07671885RecruitingPhase 3
Hormone therapy before surgery for premenopausal breast cancer
This trial tests if giving hormone-blocking pills before surgery can help guide which treatments you need after surgery. It is for premenopausal women with early-stage, hormone-sensitive breast cancer.
AkitaAges 18 years+ - NCT07460752RecruitingPhase 2
Alternative injection site for goserelin in breast cancer patients
This trial is testing whether giving the drug goserelin in a different spot on the body works just as well for suppressing ovarian function in premenopausal women with hormone receptor positive breast cancer. You may be a fit if you've already been on goserelin shots in your abdomen for at least 6 months.
Rochester, MinnesotaAges 18–50 - NCT06678048RecruitingPhase 2
Arsenous acid for hard-to-treat triple-negative breast cancer
This trial tests a medicine called arsenous acid for people with triple-negative breast cancer that has not responded to at least two prior treatments. If you join, you will get arsenous acid plus one of four chemotherapy drugs to see if the combination can shrink tumors.
Guangzhou, GuangdongAges 18–75 - NCT06678269RecruitingPhase 1
Abemaciclib and radiation for metastatic breast cancer
This trial tests whether a targeted therapy (abemaciclib) combined with focused radiation (SBRT) to a bone tumor can help people with advanced breast cancer. It is for patients whose cancer is hormone receptor positive and HER2 negative, and who will continue abemaciclib after radiation.
Basking Ridge, New JerseyAges 18 years+ - NCT05941520RecruitingPhase 2
Acolbifene vs low-dose tamoxifen to prevent breast cancer
This Phase 2 trial compares acolbifene and low-dose tamoxifen to see which better lowers breast cancer risk in premenopausal women at high risk. You would be followed with health visits, blood tests, and a breast tissue sampling procedure.
Duarte, CaliforniaAges 35 years+ - NCT06817954Recruiting
Breast reconstruction after mastectomy for breast cancer
This trial tests how safe and effective it is to remove the breast (mastectomy) and rebuild it right away during the same surgery. It is for women with early-stage breast cancer who want reconstruction instead of breast-sparing surgery.
Nanjing, JiangsuAges 18–75 - NCT06867484Recruiting
Breast re-irradiation after second lumpectomy
This trial tests whether giving a second round of radiation to the breast after a lumpectomy for a recurrence is safe and effective. It is for people with a specific type of breast cancer (ER+HER2-) who meet strict criteria regarding prior radiation and tumor characteristics.
