Rochester, MinnesotaAges 18–50 - NCT07459673RecruitingPhase 2
HER2-positive breast cancer trial using ctDNA to guide treatment
This trial tests a personalized treatment plan for HER2-positive breast cancer that has spread. It uses a blood test to track cancer DNA and adjust therapy, including treatments that may help prevent cancer from reaching the brain. The goal is to achieve long-term remission.
Basking Ridge, New JerseyAges 18 years+ - NCT07455188Recruiting
Switching targeted therapies for advanced HER2-positive breast cancer
This trial tests whether switching between two targeted therapy combinations can help women with HER2-positive advanced breast cancer that has progressed after previous treatments. It aims to find a new effective option for people who have already tried one or two lines of therapy.
Zhejiang, HangzhouAges 18 years+ - NCT06800612Recruiting
Cancer drug therapy study for gynecologic or breast cancers
This study looks at how well different cancer drugs work for women with breast or gynecologic cancers. Researchers will review medical records to see how patients responded to treatment over time. If you have been treated for breast or gynecologic cancer since 2010, you may be eligible.
BolognaAges 18 years+ - NCT06805812Recruiting
Predicting outcomes of CDK4/6 inhibitors plus hormone therapy for advanced breast cancer
This study looks at how well a type of targeted therapy (called CDK4/6 inhibitors) combined with hormone therapy works as the first treatment for advanced breast cancer that is hormone receptor-positive and HER2-negative. Researchers want to find patterns that could help predict which patients benefit most.
AvianoAges 18 years+ - NCT07439458Recruiting
Exercise effects on tumor cells in breast cancer survivors
This trial tests whether different types and intensities of exercise can change tumor-related cells in survivors of triple-negative breast cancer. It may help understand how exercise could improve long-term outcomes.
Riga, Dzirciema Street 16Ages 35 years+ - NCT07443943RecruitingPhase 2
Potato starch supplement for joint pain from hormone therapy
This trial studies whether a dietary supplement made from resistant potato starch can help reduce joint and muscle pain in people who are about to start aromatase inhibitor therapy for breast cancer or high risk. You take the supplement daily and report how you feel over 24 weeks.
Ann Arbor, MichiganAges Any age - NCT07426913Recruiting
Virtual reality heart health for breast cancer survivors
This trial tests if a virtual reality program can help breast cancer survivors taking certain chemotherapies improve their heart health. It's for people currently receiving trastuzumab or anthracycline-based treatment, along with immunotherapy, for their first breast cancer diagnosis.
Richmond, VirginiaAges 18 years+ - NCT07407920RecruitingPhase 2
Optimizing treatment for early HER2+ and triple-negative breast cancer
This trial aims to see if patients who had a complete response to chemo before surgery can safely stop or reduce their targeted therapy afterward. It includes people with early-stage HER2-positive or triple-negative breast cancer who had no cancer cells left in the tissue removed at surgery (a pathological complete response).
Houston, TexasAges 18 years+ - NCT06823414Recruiting
Robotic-assisted nipple-sparing mastectomy trial
