Testing trastuzumab deruxtecan in HER2-zero breast cancer
This trial tests a new drug called trastuzumab deruxtecan (a targeted antibody-drug combination) for people with advanced breast cancer that never showed any HER2 protein (HER2-zero). The goal is to see if it can shrink tumors and improve outcomes for those who have already had standard treatments.
New Haven, ConnecticutAges 18 years+ - NCT05150691RecruitingPhase 1/Phase 2
Early study of an HER2 drug in advanced solid tumors
This early-phase trial tests DB-1303 and BNT323 together in people with advanced or metastatic solid cancers that have specific HER2 features. It may be an option when standard treatments have stopped working, aiming to find a safer dose and early signs of effectiveness.
Cerritos, CaliforniaAges 18 years+ - NCT07586215Recruiting
HER2-PET imaging to predict response to T-DXd in advanced breast cancer
This study is testing whether a special PET scan (HER2-PET) can help predict how well the drug T-DXd (also known as Enhertu) might work for your breast cancer. T-DXd is a targeted therapy that delivers chemotherapy directly to cancer cells with certain markers. The trial will check if the scan can identify which patients are more likely to benefit, which could help personalize treatment.
ShanghaiAges 18 years+ - NCT07829848Recruiting
Skip extra radiation for breast cancer patients who respond well to treatment
This trial tests whether women and men with advanced, non-metastatic breast cancer can safely skip an extra radiation boost to the lymph nodes if their tumors respond well to pre-surgery chemotherapy or targeted therapy. The goal is to reduce side effects while keeping cancer control.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05914961Recruiting
Tracking inflammation response in triple-negative breast cancer
This trial studies how a blood inflammation marker (CRP) changes after starting immunotherapy plus chemotherapy in people with triple-negative breast cancer. Results may help doctors predict who benefits from treatment and when.
TübingenAges 18 years+ - NCT02422641RecruitingPhase 2
High-dose methotrexate for breast cancer in the brain lining
This Phase 2 trial tests whether giving high-dose methotrexate into the bloodstream can help treat breast cancer that has spread to the thin lining covering the brain and spinal cord. It may help reduce cancer in the leptomeningeal (brain-lining) area and control symptoms.
Baltimore, MarylandAges 18 years+ - NCT04293796Recruiting
Skipping breast surgery after complete response
This trial looks at whether some people with breast cancer can safely avoid breast surgery after they respond completely to treatment before surgery. If you have no remaining cancer in the tissue and lymph node tests, this study checks whether the “watch-and-wait” approach is feasible and safe.
Saint PetersburgAges 18–70 - NCT06813456Recruiting
Improving HER2 detection in breast cancer with new testing method
This trial studies a more precise way to measure HER2 levels in breast cancer tissue. It may help identify patients whose cancer is HER2-low or HER2-zero, so they can get more targeted treatment.
Bologna, BolognaAges 18 years+ - NCT05332561RecruitingPhase 2
Personalized treatment after surgery for early breast cancer
This Phase 2 study checks whether adding a personalized (biomarker-matched) medicine after standard chemotherapy and surgery lowers the risk of breast cancer coming back. Your study drug choice depends on tumor test results (from your tumor’s genetics and immune markers).
Heidelberg, Baden-WurttembergAges 18 years+ - NCT06927895Recruiting
Education program for HER2 breast cancer patients
This study is testing whether an educational program helps people with HER2 breast cancer learn more about their treatment and manage side effects. Participants will have virtual visits and watch online training videos.
New York, New YorkAges 18 years+ - NCT03561740RecruitingPhase 3
Capecitabine plus usual treatment for high-risk HER2 breast cancer
This trial looks at whether adding a chemotherapy medicine called capecitabine (taken in smaller, regular doses) to the standard after-surgery (adjuvant) treatment can lower the chance of cancer coming back in people with early-stage, high-risk HER2-positive breast cancer. It targets patients who still had cancer left after earlier treatment or who had higher-risk tumor features.
Guangzhou, GuangdongAges 18–70 - NCT07528716RecruitingPhase 3
AI-guided treatment for HER2-positive breast cancer
This trial tests whether an artificial intelligence model can help doctors choose the best targeted therapy before surgery for HER2-positive breast cancer (a type of breast cancer with a protein called HER2). The goal is to improve how well the treatment works and reduce side effects.
ShanghaiAges 18–75 - NCT06185569Recruiting

Madison, WisconsinAges 18 years+ - NCT06222957Recruiting
How HER2 affects brown fat in breast cancer patients
This study looks at how a protein called HER2 affects brown fat activity in women with breast cancer. Brown fat helps burn calories and may influence treatment outcomes. You will be assigned to one of two groups based on your cancer's HER2 status, and the study will measure how your brown fat responds to cold.
CopenhagenAges 18 years+ - NCT06214598Recruiting
Anti-inflammatory diet for breast cancer patients on hormone therapy
This study tests whether a special anti-inflammatory diet can help reduce side effects in breast cancer survivors who are taking aromatase inhibitors after menopause. You would be randomly assigned to either follow the diet for 6 months or continue your usual diet, and your health will be monitored.
BelgradeAges 45–70 - NCT06643585RecruitingPhase 3
Comparing T-DXd to standard therapy for molecular relapse in early breast cancer
This trial compares a new drug called Trastuzumab-Deruxtecan (T-DXd) to standard treatment for people with early breast cancer whose cancer has come back at a molecular level (detected by a blood test) but hasn't spread to other parts of the body. The goal is to see if T-DXd can prevent the cancer from returning.
UlmAges 18–75 - NCT06704945RecruitingPhase 3
Skipping armpit surgery after good chemo response
This trial tests whether it's safe to skip armpit surgery in people whose breast cancer has responded well to chemotherapy and whose lymph nodes appear cancer-free on ultrasound. It aims to reduce side effects like arm swelling while still controlling the cancer.
