This study tests a supervised exercise program for people with breast cancer who are about to start or are already in chemotherapy. The goal is to see if this type of rehabilitation helps keep your heart strong and improves your overall well-being during treatment.
Porto Alegre, Rio Grande do SulAges 18–65 - NCT07810088RecruitingPhase 2
Dalpiciclib with hormone therapy and blood pressure drug for advanced breast cancer
This trial is testing a new combination of medicines — a CDK4/6 inhibitor (dalpiciclib) plus hormone therapy and a blood pressure drug (olmesartan) — as a first treatment for advanced hormone-positive breast cancer. The goal is to see if this combination helps slow or shrink the cancer better than standard care.
Wuhan, HubeiAges 18–75 - NCT07776951Recruiting
Physical activity for breast cancer patients during treatment
This study tests whether a supervised physical activity program can help breast cancer patients reduce inflammation and improve health during neoadjuvant treatment (chemotherapy or immunotherapy given before surgery). The goal is to see if exercise can improve treatment outcomes and overall well-being.
MilanAges 18 years+ - NCT06559696RecruitingPhase 3
Radiation to internal mammary lymph nodes for high-risk breast cancer after chemo
This trial tests whether giving radiation to the internal mammary lymph nodes (the lymph nodes behind your breastbone) can help women with high-risk breast cancer after they have had chemotherapy before surgery. It is for people whose cancer has spread to nearby lymph nodes despite chemotherapy.
Fuzhou, FujianAges 18–75 - NCT07731477Recruiting
Virtual reality mindfulness for anxiety in breast cancer chemo
This study tests if using virtual reality for mindfulness exercises can help reduce anxiety, improve comfort, sleep, and fatigue in women with breast cancer who are about to start chemotherapy. It compares VR mindfulness to standard care.
Ankara, AnkaraAges 18 years+ - NCT07695259RecruitingPhase 4
Olaparib with trastuzumab and pertuzumab for older women with HER2+ breast cancer
This study tests a combination of two antibody drugs (trastuzumab and pertuzumab) plus a targeted pill (olaparib) given before surgery to treat elderly women with HER2-positive breast cancer. The goal is to see if this approach helps shrink tumors or eliminate them entirely before surgery.
Hangzhou, ZhejiangAges 60 years+ - NCT07673029RecruitingPhase 3
Comparing two treatments for HER2-positive breast cancer
This trial compares a new drug, GQ1005, with an existing treatment called T-DM1 for people with HER2-positive breast cancer that has spread or cannot be removed by surgery. The goal is to see which one works better for those who have already received certain other treatments.
Bengbu, AnhuiAges 18–75 - 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.
