This study builds a “genome atlas” to better predict the chance that breast cancer will come back. It asks participants to share medical information and provide blood and tumor tissue samples, including samples kept in paraffin.
TaipeiAges 20 years+ - NCT07647328RecruitingPhase 3
Camizestrant and ribociclib for advanced hormone-receptor-positive breast cancer
This trial tests a combination of two drugs (camizestrant and ribociclib) for advanced breast cancer that is hormone-receptor-positive and HER2-negative. The study aims to see if this combination helps patients whose cancer cannot be surgically removed or treated with radiation alone.
Duarte, CaliforniaAges 18–130 - NCT06693037Recruiting
Choosing next treatment after incomplete response in HER2+ breast cancer
This trial looks at the best next treatment for women with HER2-positive breast cancer who still have leftover cancer after surgery and standard pre-surgery treatment. It helps doctors choose the right therapy for you.
Beijing, Beijing MunicipalityAges Any age - NCT06711185RecruitingPhase 3
Can dapagliflozin protect breast cancer patients' hearts during chemo?
This trial tests if a diabetes medicine called dapagliflozin (also known as Farxiga) can protect the hearts of women with breast cancer while they receive anthracycline chemotherapy. You would take the medicine and have heart MRI scans to see if it helps prevent heart damage.
Campinas, São PauloAges 18 years+ - NCT06304857RecruitingPhase 3
Protecting the heart with dapagliflozin during breast cancer treatment
This trial tests if the diabetes drug dapagliflozin can protect the heart in people with breast cancer receiving a type of chemotherapy called anthracyclines. You may be able to join if you are between 18 and 80, have stage I-III breast cancer, and are about to start anthracycline treatment within the next 60 days.
Wroclaw, Lower Silesian VoivodeshipAges 18–80 - NCT07563621Recruiting
Understanding Vaginal Health Changes in Breast Cancer Survivors
This study examines vaginal dryness and discomfort—common side effects of breast cancer treatment—in women who've survived the disease. Researchers want to understand how often this happens and how much it affects daily life, which may help doctors better support survivors.
Hasselt, LimburgAges 18 years+ - NCT07514728Enrolling by invitation
Hyperbaric oxygen to slow breast cancer spread to lungs
This trial tests whether hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can slow the growth of breast cancer that has spread to the lungs. You would receive this treatment alongside standard care if your cancer has grown despite prior chemotherapy.
Jinan, ShandongAges 18–75 - NCT07490938Recruiting
Acupuncture for joint pain from breast cancer hormone therapy
This trial compares two types of acupuncture (electroacupuncture and ear acupressure) with standard care to see if they can help relieve joint pain caused by hormone therapy for breast cancer. It may be a good option if you have ongoing joint pain and are continuing hormone therapy.
Wuhan, HubeiAges 18–75 - NCT06773533Recruiting
Bone health in breast cancer hormone-blockade patients
This study tracks bone health in breast cancer patients receiving hormone-blocking therapy (aromatase inhibitors, GnRH analogs, or tamoxifen). It aims to understand how these treatments affect bone mineral density.
Bologna, BolognaAges 18 years+ - NCT06741540Recruiting
TDCS for breast cancer patients with mild to moderate depression
This trial tests if transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, can help improve mood and treatment outcomes in breast cancer patients with mild to moderate depression who are receiving neoadjuvant chemotherapy before surgery.
Hangzhou, ZhejiangAges 18–65 - 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 - NCT07402473RecruitingPhase 2
Optimizing treatment before surgery for HER2-positive breast cancer
This trial tests a neoadjuvant (before surgery) treatment plan for people with early-stage HER2-positive breast cancer. The goal is to see if a personalized approach can improve outcomes.
