Recruiting studies
- NCT07616258Recruiting
Reducing follow-up visits after breast cancer treatment
This study tests whether some patients who finished curative breast cancer treatment can safely have fewer follow-up appointments and scans. Researchers want to see if less frequent monitoring is safe for patients without any signs of cancer returning.
Beaumont, DublinAges 18 years+ - NCT07617025Recruiting
Understanding Breast Cancer Subtypes in BRCA Carriers
This study examines how different molecular subtypes (patterns of genes and proteins) of breast cancer behave in people with BRCA1 or BRCA2 mutations. By studying tumor samples and medical records, researchers hope to better predict which treatments will work best and predict long-term outcomes for BRCA-positive breast cancer patients.
GenovaAges 18 years+ - NCT07658170Recruiting
Fat graft with platelet-rich fibrin for breast reconstruction after lumpectomy
This trial tests using a patient's own fat plus a special blood product (platelet-rich fibrin) to rebuild the breast right after a lumpectomy for breast cancer. It may help improve healing and appearance for women with early-stage, hormone-sensitive breast cancer.
Saint PetersburgAges 18–69 - NCT07651345Enrolling by invitation
Helping Women Return for Overdue Breast Cancer Screening
This study tests different ways to encourage women in Singapore to return for mammograms (breast cancer screening) if they've fallen behind. You'd be randomly assigned to receive different types of reminders or support to help you schedule your screening.
SingaporeAges 50–69 - NCT07483034Enrolling by invitation
Music therapy for anxiety during breast cancer treatment
This study tests whether listening to specially chosen music while you're in the hospital for breast cancer treatment can help lower anxiety and depression. It also looks at how music might affect certain substances in your blood that are linked to stress and healing.
Zagreb, City of ZagrebAges 18–65 - NCT07292571Enrolling by invitationPhase 2
Tracing breast cancer HER2 with a special scan
This study uses a radioactive tracer to see how much HER2 protein is on your breast cancer cells. The scan may help doctors understand the type of HER2 you have and choose the best treatment.
TomskAges 18–80 - NCT07275463Enrolling by invitationPhase 2
Study of DB8 imaging in estrogen receptor positive and negative breast cancer
This trial uses a special imaging agent called DB8 to see how it builds up in breast tumors. It compares results between women with estrogen receptor-positive and estrogen receptor-negative cancers to help improve detection.
TomskAges 18–80 - NCT06843096Enrolling by invitation
Special mammogram for finding breast cancer when origin is unknown
This trial uses a special mammogram with contrast dye to look for breast cancer in people who have cancer that started somewhere unknown (called Cancer of Unknown Primary). It may help find if the breast is the source, which could guide treatment.
RomeAges 18 years+ - NCT06843083Enrolling by invitation
Which advanced breast scan is better for you?
This study compares two advanced breast imaging methods—contrast-enhanced mammography (CEM) and breast MRI—to see which is better at finding cancer, especially in women with dense breasts or unclear mammogram results. If you are being referred for one of these exams, you may be able to join and help doctors learn which test works best.
NaplesAges 18 years+ - NCT06223022Enrolling by invitation
Nurse phone calls after cancer treatment ends
This trial tests whether regular phone calls from a nurse can help patients after they finish their main cancer treatment. It focuses on breast, colorectal, or prostate cancer that was treated with a goal to cure.
UmeåAges 18 years+ - NCT05400941Enrolling by invitation
Breast cancer follow-up support in primary care
This study looks at how breast cancer follow-up care can be better done in primary care clinics. It may help by improving care check-ins and support for people who have had breast cancer and for clinic staff involved in that care.
New Brunswick, New JerseyAges 21 years+ - NCT04098640Enrolling by invitation
Testing tumor DNA in younger people with metastatic breast cancer
This study looks at your tumor’s molecular (DNA/biologic) features to better understand metastatic breast cancer in people under 50. You may help researchers by providing tissue samples (biopsies) for lab testing.
Seoul, SeoulAges 19–50 - NCT05848141Recruiting
Rowing program after breast cancer treatment
This study looks at whether supervised rowing exercise after breast cancer treatment is safe and helpful for recovery and health. You may be able to join if you finished treatment within the last 6–24 months and have no major exercise-limiting heart or health problems.
Gainesville, FloridaAges 40–80 - NCT05501704RecruitingPhase 2
Testosterone-blocking therapy for male breast cancer
This Phase 2 study tests an oral treatment (called “ET”) to treat hormone-receptor–positive, HER2-negative invasive breast cancer in men. It may help shrink or control cancer without using standard cancer treatments first.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05876065Recruiting
Maintenance chemotherapy to help control advanced breast cancer
This trial studies whether taking a combination of capecitabine and cyclophosphamide after your best prior treatment can help keep advanced breast cancer from growing. It may help people whose disease has already responded or is stable after “salvage” treatment.
ShanghaiAges 18 years+ - NCT02102165Recruiting
Study samples from metastatic triple-negative breast cancer
This study looks at tumor “clues” by using tissue and blood samples in people with metastatic breast cancer (with specific subtype). It aims to better understand what drives the cancer, which may help guide future treatments.
BrusselsAges 18 years+ - NCT06026657RecruitingPhase 1/Phase 2
NK cells with or without naxitamab for GD2-positive breast cancer
This trial tests a new treatment using immune cells called NK cells combined with chemotherapy (gemcitabine) and possibly naxitamab for people with a certain type of advanced breast cancer that has spread. It aims to see if this approach can help when standard treatments have stopped working.
Columbus, OhioAges 18 years+ - NCT05505357Recruiting
Skip breast surgery after excellent MRI response
This trial tests whether some women with HER2-positive breast cancer can safely avoid breast surgery if their tumor nearly disappears after chemotherapy. It uses MRI and biopsy results to find people most likely to have no remaining cancer (pCR).
SeoulAges 20 years+ - NCT07180082RecruitingPhase 2
Pyrotinib for HER2-positive advanced breast cancer
This trial tests whether taking pyrotinib continuously or intermittently can help people with HER2-positive advanced breast cancer that has spread. It is for those who have already received prior treatment for their advanced disease.
ShanghaiAges 18 years+ - NCT06486883RecruitingPhase 2
T-DXd vs CDK4/6i plus hormone therapy for advanced HR-positive, HER2-low breast cancer
This trial compares two treatments for advanced breast cancer that is HR-positive, HER2-low or ultralow, and a non-luminal subtype. It tests if a targeted antibody-drug conjugate (T-DXd) works better than the usual first-line therapy combining a CDK4/6 inhibitor with hormone therapy. This study is for people who have not had any treatment for advanced disease.
GrazAges 18 years+ - NCT06734533Recruiting
Anlotinib combo for HR+ breast cancer that has spread
This trial tests a combination treatment including anlotinib for women with hormone receptor-positive breast cancer that has spread to other parts of the body and has stopped responding to standard therapies. It is for those who have already tried a CDK4/6 inhibitor and endocrine therapy.
Changsha, HunanAges 18–75 - NCT06380751RecruitingPhase 3
New targeted therapy for BRCA/PALB2-mutated HR+ breast cancer
This trial tests a new combination of targeted therapies (saruparib plus camizestrant or hormone therapy) against standard treatments for people with a specific type of advanced breast cancer. It may be a good option if you have a BRCA1, BRCA2, or PALB2 gene mutation and have not yet had treatment for your advanced disease.
Gilbert, ArizonaAges 18 years+ - NCT06658912Recruiting
Weight loss program for breast cancer survivors
This study tests a weight loss program designed specifically for women who have finished breast cancer treatment. It aims to help improve overall health after cancer.
