Maastricht, LimburgAges 18 years+ - NCT06690645Recruiting
Stress and breast cancer treatment response
This trial studies how psychological stress might affect the success of pre-surgery breast cancer treatments (neoadjuvant therapy). If you are about to start treatment and have never had cancer therapy before, this study could help doctors understand your response better.
Shenyang, LiaoningAges 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+ - NCT07630402Recruiting
Heart Imaging Study for Women With Early Breast Cancer
This study helps doctors find the best way to monitor heart health in women with HER2-positive breast cancer who are receiving a type of targeted chemotherapy. The goal is to catch any heart problems early and keep you safe during treatment.
Rochester, New YorkAges 18–79 - NCT07635147Recruiting
