- NCT05977036Recruiting
Biomarker test to guide early treatment for HR+ HER2- breast cancer
This study uses a lab “biomarker” test to help doctors choose the best first treatment for people with HR+ (hormone-receptor positive), HER2-negative metastatic or unresectable breast cancer. The goal is to see if this biomarker-guided approach can improve which therapy you start with.
St Louis, MissouriAges 18 years+ - NCT05992870Recruiting
Radiation before breast reconstruction with implants
This trial tests giving radiation therapy before surgery and immediate breast reconstruction using implants. It may help patients who need a mastectomy and know they will need radiation after.
Wuhan, HubeiAges 18–75 - NCT06035016Recruiting
Pyrotinib and capecitabine after surgery for HER2+ breast cancer
This study tests whether taking pyrotinib (a daily pill) with capecitabine (another pill) after breast cancer surgery can help prevent HER2-positive early-stage breast cancer from coming back. It is for women who have already had their cancer removed and meet certain risk criteria.
Beijing, Beijing MunicipalityAges 18–75 - NCT06044623RecruitingPhase 3
Tailoring cancer pill dosing for older adults with breast cancer
This trial is testing whether adjusting the dose of a targeted therapy (CDK 4/6 inhibitor) based on a geriatric assessment can be as effective and safer for people aged 70 and older with advanced hormone receptor-positive, HER2-negative breast cancer. It aims to find the best dose to balance benefits and side effects.
HelsinkiAges 70 years+ - NCT06052488Recruiting
Strength After Breast Cancer
This study tests a strength training program for women who have finished primary treatment for early-stage breast cancer. The goal is to see if it helps improve muscle strength and overall recovery.
Boston, MassachusettsAges 18 years+ - NCT06127797Recruiting
MRI surveillance study for breast cancer survivors with dense breasts
This study is testing whether adding an MRI to your regular mammogram can help find any new breast cancers earlier. It is for women who have had breast cancer before and still have dense breast tissue, making mammograms harder to read.
Houston, TexasAges 18 years+ - NCT06135714RecruitingPhase 3
Targeting limited breast cancer spread with focused therapy
This trial tests whether treating just the few spots where breast cancer has spread (called oligometastases) with radiation or surgery can help control the disease. It is for people whose cancer has spread to 3 or fewer places, each small in size, and who are healthy enough for local treatments.
Tokyo, TokyoAges 18–80 - NCT06144346Recruiting
Radiation for limited breast cancer spread
This trial tests whether treating each spot of cancer that has spread (but only a few spots) with focused radiation can help control breast cancer. It aims to see if this approach can stop the cancer from growing further without needing strong whole-body treatments right away.
CairoAges 18–70 - NCT06150898RecruitingPhase 2
Ketorolac and pregabalin for estrogen receptor positive breast cancer before surgery
This trial tests whether two medications, ketorolac (a pain reliever) and pregabalin (a nerve pain drug), can help treat estrogen receptor (ER) positive breast cancer when taken before surgery. It may offer better pain control and possibly improve cancer outcomes.
Brussels, Brussels CapitalAges 18–70 - NCT06182306Recruiting
Testing a tool to guide treatment for triple-negative breast cancer
This study is testing a research tool that may help doctors choose the best treatment for people with advanced triple-negative breast cancer. You will have a biopsy and blood draw to help see how the tool works.
LondonAges 18 years+ - NCT06185205RecruitingPhase 2
Accelerated high-dose radiation for early breast cancer
This trial tests a very short, high-dose radiation treatment given directly to the breast after lumpectomy. It aims to make radiation more convenient by finishing in just a few days instead of weeks, possibly with fewer side effects.
Richmond, VirginiaAges 45–79 - NCT06197581Recruiting
Safety of Radiation with Modern Breast Cancer Drugs
This study checks if giving certain modern breast cancer drugs at the same time as radiation is safe. It's for women who need radiation and are also taking one of these drugs: capecitabine, a CDK4/6 inhibitor, a PARP inhibitor, immunotherapy, or a HER2 inhibitor.
Beijing, Beijing MunicipalityAges 18–70 - NCT06201234RecruitingPhase 2
Adding elacestrant to olaparib for advanced HR+/HER2- breast cancer
This trial tests if adding a new oral medicine (elacestrant) to a standard PARP inhibitor (olaparib) works better for people with advanced or metastatic HR+/HER2- breast cancer who have a BRCA1 or BRCA2 gene mutation. The goal is to see if the combination can help control the cancer longer.
Stuttgart, Baden-WurttembergAges 18 years+ - NCT06202261RecruitingPhase 1/Phase 2
Study of TQB2930 for breast cancer that has returned or spread
This trial tests a new drug called TQB2930 alone or with other treatments for people with recurrent or metastatic breast cancer. It may help if you have a type of breast cancer called HER2-positive and have not had many prior treatments for advanced disease.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT06225284RecruitingPhase 2
Chemotherapy with or without hormone drug for premenopausal TNBC
This trial tests whether adding a hormone-blocking drug (GnRH agonist) to standard chemotherapy before surgery helps premenopausal women with triple-negative breast cancer. It aims to improve treatment outcomes by targeting hormones that may fuel tumor growth.
TaipeiAges 18 years+ - NCT06236269RecruitingPhase 2
Sacituzumab Govitecan for HR+/HER2- advanced breast cancer
This trial tests a drug called Sacituzumab Govitecan for people with HR+/HER2- advanced or metastatic breast cancer that has stopped responding to a CDK4/6 inhibitor. It looks at whether the drug can slow down the cancer and requires you to have a tumor biopsy.
Badalona, BarcelonaAges 18 years+ - NCT06238921RecruitingPhase 1/Phase 2
Study of two drugs and radiation for triple-negative breast cancer that spread to the brain
This trial tests adding the drugs sacituzumab govitecan and zimberelimab to targeted radiation therapy for people with triple-negative breast cancer that has spread to the brain. The goal is to see if this combination helps control the cancer longer.
Tampa, FloridaAges 18 years+ - NCT06253871RecruitingPhase 1
Study of IAM1363 for HER2 Cancers
This trial tests a new oral drug called IAM1363 for people with HER2-altered cancers that have stopped responding to previous treatments. The goal is to see if the drug is safe and how well it works against these cancers.
La Jolla, CaliforniaAges 18 years+ - NCT06259513Recruiting
Skipping armpit surgery for breast cancer patients
This trial tests whether it's safe to skip armpit surgery in older women with small, low-risk breast cancers. If you qualify, you would have a mastectomy without removing lymph nodes from your armpit.
SingaporeAges 21–80 - NCT06264934Recruiting
Testing a new breast scanner using electric fields
This study is testing a new type of scanner that uses safe electric fields to create images of breast tissue. It may help doctors see breast changes without needing a biopsy or X-ray. By joining, you help researchers understand how well this scan works.
LondonAges 18 years+ - NCT06266026Recruiting
AI-enhanced thermal imaging for breast cancer screening
This study tests a new, non-contact thermal camera (thermography) combined with artificial intelligence to find breast cancer. It is designed for women coming for routine screening, high-risk screening, or diagnostic exams, and aims to see if this painless, radiation-free method can help detect cancer earlier.
HeidelbergAges 18 years+ - NCT06268652RecruitingPhase 3
Personalized treatment guided by lab-grown tumor samples for advanced breast cancer
This trial tests whether using a personalized approach—growing your tumor cells in the lab to find the best treatment—can work better than standard treatments chosen by your doctor. It is for people with advanced breast cancer that has stopped responding to at least two previous treatments.
Guangzhou, None SelectedAges 18 years+ - NCT06276868RecruitingPhase 2
Darsilide plus hormone therapy and double antibody for breast cancer
This trial tests if adding a new drug (darsilide) to standard hormone therapy and two antibodies (trastuzumab and pertuzumab) before surgery can improve outcomes for women with HR-positive, HER2-positive breast cancer that hasn't spread.
Henan, HenanAges 18–70 - NCT06291064RecruitingPhase 2
