Recruiting studies
- NCT07371585RecruitingPhase 2
Trastuzumab Deruxtecan for first-line HER2-positive advanced breast cancer
This trial tests a targeted therapy called Trastuzumab Deruxtecan (T-DXd) for people with HER2-positive breast cancer that has spread or cannot be removed. It is for those who have not yet received any chemotherapy or HER2-targeted treatment for metastatic disease. The study also focuses on managing side effects early, using digital tools to track symptoms.
VillejuifAges 18 years+ - NCT07373782RecruitingPhase 2/Phase 3
CPAP mask during radiation for breast cancer
This trial tests whether using a CPAP mask during daily radiation treatments for breast cancer can help protect your heart. It is for women who had a lumpectomy and need radiation to the left breast or to the right breast with lymph nodes.
LeuvenAges 40–80 - NCT07376538RecruitingPhase 2
Treating advanced breast cancer based on treatment response
This trial tests a personalized approach to treating breast cancer that has spread to nearby lymph nodes. Your surgery and radiation will be tailored to how well your cancer responds to initial chemotherapy or hormone therapy.
Beijing, Beijing MunicipalityAges 18–75 - NCT07379918Recruiting
Evaluating Endopredict® test in early HR+/HER2- breast cancer
This study looks at how well the Endopredict® genomic test helps doctors decide whether chemotherapy should be added to hormone therapy for people with early-stage, HR+/HER2- breast cancer. It is for those whose standard criteria are not enough to make a clear recommendation.
ParisAges 18 years+ - NCT01503190Recruiting
Study of how breast cancer affects the immune system
This study looks at how the immune system changes in people with breast cancer, using patient tissue samples. It may help researchers understand immune responses in young women and guide future cancer treatments.
Aurora, ColoradoAges 18 years+ - NCT00898131Recruiting
Donate tissue samples during breast cancer surgery for future research
This study collects small tissue samples from women having surgery for breast cancer. The samples are stored to help researchers learn more and develop better treatments in the future.
Chicago, IllinoisAges Any age - NCT01185132RecruitingPhase 3
IMRT versus partial-breast radiation after lumpectomy
This study compares two different ways of giving radiation to the breast after lumpectomy for early-stage breast cancer. It may help determine which approach controls the cancer well while reducing radiation to surrounding healthy tissue.
Aurora, ColoradoAges 40 years+ - NCT01766297RecruitingPhase 2
Proton radiation after lumpectomy for early breast cancer
This trial studies a type of radiation made with protons to treat only part of the breast after surgery (lumpectomy) for early-stage breast cancer. It may help control the cancer while aiming to reduce radiation to surrounding tissues.
Scottsdale, ArizonaAges 50 years+ - NCT02732860Recruiting
Test your tumor’s drug response using a lab model
This trial grows a lab model from your own tumor tissue (or resected tissue) to predict which drugs might work best. It’s meant to match investigational treatments to your specific tumor biology.
Toronto, OntarioAges 18 years+ - NCT02476786RecruitingPhase 2
Hormone treatment only for older ER-positive breast cancer
This Phase 2 study tests whether using hormone (endocrine) treatment alone can control breast cancer in people age 70 and older. It targets breast cancers that are estrogen-receptor positive and HER2 negative, aiming to avoid chemotherapy-like treatments in suitable patients.
St Louis, MissouriAges 70 years+ - NCT02732171Recruiting
Blood and bone marrow tests to track breast cancer return
This trial checks whether specific “surveillance” markers (measured from blood and bone marrow) can help predict if breast cancer comes back after standard treatments. It may help doctors monitor you more accurately and earlier if recurrence risk is high.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02830724RecruitingPhase 1/Phase 2
CAR T therapy using blood immune cells for CD70 cancers
This trial tests a personalized immune-cell treatment (CAR T) built from your own blood lymphocytes. It targets cancers that show a marker called CD70, aiming to slow or stop the cancer when other treatments didn’t work.
Bethesda, MarylandAges 18–72 - NCT02535221RecruitingPhase 3
Hormone treatment vs chemotherapy before breast surgery
This Phase 3 trial compares hormone-based treatment versus chemotherapy given before surgery in people who are premenopausal and have hormone-receptor positive, HER2-negative breast cancer. It looks to see which approach works better to control the cancer before the breast operation.
BeijingAges 35–55 - NCT02926690RecruitingPhase 1
MELK inhibitor safety study for advanced breast cancer
This Phase 1 study tests how safe a drug called an MELK inhibitor is in people with advanced breast cancer that has spread or cannot be removed with surgery. If you qualify, the study is focused on side effects and includes a special group for triple-negative breast cancer.
Norwalk, ConnecticutAges 18 years+ - NCT02945579Recruiting
Testing skipping breast surgery or radiation for top responders
This trial studies whether some people with early-stage breast cancer who respond extremely well to hormone/chemo/targeted treatment can safely skip breast surgery and/or radiation. It aims to reduce side effects without increasing cancer risk in carefully selected patients.
Gilbert, ArizonaAges 30 years+ - NCT07527689Recruiting
Faster vs. Standard Radiation After Breast Cancer Surgery
This study compares two radiation schedules for breast cancer patients at high risk of cancer returning in lymph nodes. Both use modern radiation therapy, but one delivers treatment faster (ultra-hypofractionated) while the other uses a more moderate schedule. The goal is to see which approach works better with fewer side effects.
ShanghaiAges 18 years+ - NCT07443579Recruiting
Mammogram order study for breast cancer survivors
This trial tests if changing the order of mammogram views makes the exam more comfortable for women who have had breast cancer surgery and radiation. You may be able to join if you are due for your first check-up mammogram after finishing treatment.
Beaumont, DublinAges 18 years+ - NCT07447414Recruiting
Freezing small hormone-driven breast cancers
This study tests cryoablation (freezing) to treat small, early stage breast cancers that are hormone receptor positive and HER2 negative. It may be an option for postmenopausal women who want to avoid surgery.
Lugo, LugoAges Any age - 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+ - 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+ - NCT07467824Recruiting
Exercise and support before and after breast cancer treatment
This trial tests whether a program of supervised exercise and full follow-up before and after breast cancer treatment can improve recovery and quality of life for women with early-stage breast cancer.
Valladolid, ValladolidAges 18–65 - NCT07478900Recruiting
Tattoo marking breast tumors before chemo
This trial tests a simple method: marking the tumor with a small tattoo before chemotherapy. The tattoo helps surgeons find the exact spot for lumpectomy after the tumor shrinks, so you can keep more of your breast.
Bhubaneswar, OdishaAges 18–75 - NCT07483307RecruitingPhase 2
Hormone therapy before surgery for lobular breast cancer
This trial tests whether taking hormone therapy before surgery can improve outcomes for women with a specific type of breast cancer called lobular breast cancer. If you qualify, you would receive endocrine therapy for 6 months before your planned breast-conserving surgery.
Basking Ridge, New JerseyAges 50 years+ - NCT07484087Recruiting
Ablation vs. Surgery for Early Breast Cancer
This trial compares a less invasive treatment called ablation (which uses extreme cold to destroy the tumor) with standard surgery for early-stage breast cancer. It is for women aged 50 or older with a small, low-risk tumor that has not spread.
