This trial looks at whether giving radiation treatment to tumors in people with a limited number of metastases can help control the cancer. It is for adults with certain cancer types that have spread to specific organs, and who can manage daily activities with little or no help.
Albacete, AlbaceteAges 18 years+ - 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+ - NCT03971045RecruitingPhase 2
Pembrolizumab plus low-dose oral chemo for chest wall breast cancer
This Phase 2 trial tests pembrolizumab (an immune therapy) plus low-dose oral cyclophosphamide in people with chest wall breast cancer that has spread locally and may have distant metastases. It aims to see if this combination can shrink tumors and control cancer longer, especially in tumors with certain immune markers.
MilanAges 18 years+ - NCT07630961RecruitingPhase 1
New PET Imaging Scans for Advanced Solid Tumors
This trial tests two new radioactive imaging scans (called PET scans) designed to better detect certain advanced cancers like pancreatic, lung, breast, colon, or soft-tissue tumors. The goal is to see if these scans help doctors find and track cancer more accurately than standard imaging.
Odense CAges 18 years+ - NCT07631052RecruitingPhase 2
Low-dose Capecitabine for High-risk Early Breast Cancer
This study tests whether a low-dose chemotherapy pill called capecitabine can help prevent breast cancer from coming back in patients whose cancer shows signs of remaining disease (called MRD) despite standard treatment. The trial focuses on hormone-receptor-positive, HER2-negative breast cancers.
Toronto, OntarioAges 18 years+ - NCT07635147Recruiting

Minneapolis, MinnesotaAges 18 years+ - NCT06587789Recruiting
Ribociclib plus hormone therapy for high-risk breast cancer
This trial tests adding ribociclib (a targeted pill) to standard hormone therapy for people with early but high-risk HR-positive, HER2-negative breast cancer, after surgery.
Hangzhou, ZhejiangAges 18–80 - NCT06102824RecruitingPhase 2
Organoid-guided treatment for advanced breast cancer
This trial tests whether using a miniature version of your tumor grown in a lab can help choose the best treatment for advanced breast cancer. It compares this personalized approach to standard care.
Guangzhou, GuangdongAges 18–80 - NCT06222879RecruitingPhase 1/Phase 2
New drug combinations for advanced breast cancer
This trial tests a combination of new drugs (HRS-8080, SHR-A2009, or others) for people with advanced breast cancer that has stopped responding to previous treatments. The goal is to see if these combinations can shrink tumors or slow the cancer's growth.
Changsha, HunanAges 18–75 - NCT07619534Recruiting
Collecting Spinal Fluid from Advanced Breast Cancer Patients
This study collects spinal fluid samples from people with advanced (metastatic) HER2-positive or triple-negative breast cancer who have never had, and currently do not have, cancer spread to the brain. Researchers want to understand how cancer cells might reach the nervous system and develop better treatments.
Bethesda, MarylandAges 18–120 - 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.
