This study tests whether a supervised at-home (telehealth) strength exercise program can help older women stay strong and keep their chemotherapy on schedule. It’s meant for women who are starting chemotherapy for breast cancer with the goal of cure.
Boston, MassachusettsAges 65 years+ - NCT07661927RecruitingPhase 2
Skipping hormone therapy for low-risk breast cancer
This trial tests whether women with very low-risk, early-stage breast cancer can safely skip hormone therapy after surgery. It is designed for women who are 60 or older and whose cancer shows no spread to lymph nodes and has favorable biology.
AngersAges 60 years+ - NCT06452485Recruiting
Re-irradiation with or without hyperthermia, or surgery only for recurrent breast cancer
This trial compares three treatment options for breast cancer that has come back in the chest or lymph nodes after previous radiation. It looks at adding hyperthermia (heating the tumor area) to re-irradiation, versus just re-irradiation or surgery alone, to see which offers better quality of life and survival with fewer side effects.
AmsterdamAges 18 years+ - NCT07708194RecruitingPhase 1/Phase 2
Entinostat plus pyrotinib and hormone therapy for advanced breast cancer
This trial tests a new combination of two targeted drugs (entinostat and pyrotinib) with hormone therapy for people with advanced, triple-positive breast cancer whose disease has progressed after trastuzumab (Herceptin). The goal is to see if this approach works better than current options.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT06555068RecruitingPhase 1/Phase 2
Study of HRS-6209 combinations for advanced breast cancer
This trial tests a new drug, HRS-6209, combined with different hormone treatments (fulvestrant, letrozole, HRS-8080, or HRS-1358) for people with advanced breast cancer that has spread or cannot be surgically removed and has worsened after previous treatments.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06640881RecruitingPhase 2
Repeat breast-conserving surgery with partial reirradiation
This trial tests a new approach for women whose breast cancer has returned in the same breast after earlier surgery and radiation. Instead of removing the whole breast, doctors will remove only the tumor again and give a small, focused dose of radiation before surgery, aiming to preserve the breast.
AmsterdamAges 50 years+ - NCT05350722Recruiting
Single pre-surgery radiation for low-risk breast cancer
This trial tests a single, shorter course of radiation given before breast surgery for people with low-risk, hormone-receptor–positive breast cancer. It may help treat the breast tumor while reducing the number and length of radiation treatments.
SydneyAges 40 years+ - NCT07264985Recruiting
Gut bacteria and diarrhea in breast cancer patients on pyrotinib
This study looks at how gut bacteria relate to diarrhea in breast cancer patients who are taking a drug called pyrotinib. By understanding this link, doctors hope to better manage side effects in the future.
Wuhan, HubeiAges 18–75 - NCT05996107RecruitingPhase 1
Ribociclib with radiation for high-risk HR+ breast cancer
This trial tests whether adding the targeted therapy ribociclib (Kisqali) to radiation after surgery reduces the risk of breast cancer returning in patients with high-risk, hormone-positive breast cancer.
Ann Arbor, MichiganAges 18 years+ - NCT03150576RecruitingPhase 2/Phase 3
Before-surgery treatment for triple-negative or BRCA breast cancer
This trial tests an “at-the-source” medicine given before surgery to shrink triple-negative and/or BRCA-related breast cancer. It may help doctors see whether it improves tumor response and reduces cancer spread at surgery time.
Cambridge, CambridgeshireAges 16–70 - NCT03201861RecruitingPhase 3
Cisplatin added after surgery for high-risk breast cancer
This trial checks whether adding cisplatin to standard chemotherapy after surgery helps women with high-risk early-stage breast cancer lower the chance of the cancer coming back. You would be followed to see how well treatment works and whether it is tolerated.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT03265379Recruiting
Registry study for breast cancer invading the chest wall
This study follows people with breast cancer that has spread into the chest wall who are planning full-thickness chest wall surgery. It aims to improve quality of life by collecting real-world information during and after treatment.
Toronto, OntarioAges 18 years+ - NCT03418961RecruitingPhase 3
Study of heart-risk management for metastatic HER2 breast cancer
This trial follows people with metastatic HER2-positive breast cancer who are at higher risk for heart damage while on HER2-targeted therapy. Some participants are randomly assigned to different monitoring/heart-protection approaches to see what best helps keep the heart safe.
Anchorage, AlaskaAges 18 years+ - NCT03436069Recruiting
Finding new markers to predict breast cancer outlook
This study looks for new lab “markers” that may help predict how breast cancer is likely to behave over time. Your tumor or health information may be used to find factors that can guide doctors’ predictions.
GrenobleAges 18 years+ - NCT03449238RecruitingPhase 1/Phase 2
Pembrolizumab with focused brain radiation for breast cancer brain spread
This trial studies whether pembrolizumab (an immune therapy medicine) plus stereotactic radiosurgery (focused radiation) can better control brain metastases from breast cancer. It may help shrink or slow growth of multiple brain spots with minimal treatment to surrounding tissue.
New York, New YorkAges 19–90 - NCT03451383Recruiting
Study brain changes in older breast cancer patients
This study follows older women with newly diagnosed breast cancer to see who might develop thinking or memory problems over time. It may help researchers understand early brain risk and how treatment and other factors relate to cognitive decline.
