Houston, TexasAges 18 years+ - NCT03990896RecruitingPhase 2
Talazoparib for metastatic breast cancer with BRCA body DNA changes
This Phase 2 trial tests talazoparib, a targeted cancer medicine, in people with metastatic breast cancer that has a harmful BRCA1 or BRCA2 mutation found in tumor DNA circulating in the blood. If you qualify, the goal is to see how well this treatment works when the mutation is detected this specific way.
San Francisco, CaliforniaAges 18 years+ - NCT03723928Recruiting
Blood test–guided monitoring for metastatic breast cancer treatment
This study checks whether specific blood “tumor marker” levels can help monitor how hormone receptor–positive, HER2-negative metastatic breast cancer responds to first-line therapy. It uses regular blood tests (and sometimes scans) to see if this marker-based monitoring is useful and reliable.
Anchorage, AlaskaAges 18 years+ - NCT03606967RecruitingPhase 2
Individualized vaccine added to standard treatment for metastatic triple-negative breast cancer
This Phase 2 trial tests whether adding a personalized cancer vaccine to durvalumab (an immunotherapy), tremelimumab (another immunotherapy), and chemotherapy can improve outcomes for people with metastatic triple-negative breast cancer. It may help your immune system recognize your specific tumor features.
Orange, CaliforniaAges 18 years+ - 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+ - 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+ - NCT02102165Recruiting
Study samples from metastatic triple-negative breast cancer
This study looks at tumor “clues” by using tissue and blood samples in people with metastatic breast cancer (with specific subtype). It aims to better understand what drives the cancer, which may help guide future treatments.
BrusselsAges 18 years+ - NCT06598046RecruitingPhase 2
Utidelone and Capecitabine for triple-negative breast cancer brain metastases
This trial tests a combination of two chemotherapy drugs (Utidelone and Capecitabine) for people with triple-negative breast cancer that has spread to the brain. The goal is to see if the combination can shrink or control the brain tumors.
Zhengzhou, HenanAges 18 years+ - NCT06176534RecruitingPhase 2
Comparing two treatments for advanced breast cancer with low hormone receptor
This trial compares two treatment options for advanced breast cancer that has low hormone receptor levels and is HER2-negative. It tests whether a combination of chemotherapy followed by maintenance therapy works better than a CDK4/6 inhibitor combined with hormone therapy. This is for people who have not had chemotherapy for their advanced disease.
