This Phase 2 trial tests strategies meant to “prime” the immune system so that immune checkpoint medicines may work better in people with triple-negative breast cancer that has spread (or can’t be fully cured). You might be considered if your cancer has measurable areas that can be biopsied and you meet specific health and prior-treatment rules.
AmsterdamAges 18 years+ - NCT04289935Recruiting
Vacuum biopsy before surgery to check treatment response
This trial studies a special vacuum-assisted biopsy taken just before breast surgery to see how well pre-surgery (neoadjuvant) chemotherapy worked. It may help doctors understand whether patients truly had a complete or near-complete response on scans, which can guide next steps.
SalzburgAges 18 years+ - NCT04303988RecruitingPhase 2
Trial for brain metastases from triple-negative breast cancer
This Phase 2 study tests a treatment for people with triple-negative breast cancer that has spread to the brain. It’s designed for situations where the cancer can’t be safely cured with surgery or focused radiation.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT04305834RecruitingPhase 2
Abemaciclib plus hormone pills for metastatic breast cancer in older adults
This Phase 2 study tests whether abemaciclib combined with standard hormone (endocrine) therapy can better control metastatic breast cancer in people age 70 and older. It may help if your cancer has already grown despite prior hormone therapy and/or other cancer medicines.
Duarte, CaliforniaAges 70 years+ - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT04468061RecruitingPhase 2
Study chemo drug plus immunotherapy for metastatic triple-negative breast cancer
This trial tests sacituzumab govitecan (an antibody-drug medicine) with or without pembrolizumab (an immune-system therapy) in people with metastatic triple-negative breast cancer. It may help by shrinking tumors and improving immune control, especially for patients with specific tumor marker results.
Stamford, ConnecticutAges 18 years+ - NCT04481763RecruitingPhase 1/Phase 2
Camrelizumab plus radiation for early triple-negative breast cancer
This trial studies whether adding camrelizumab (an immunotherapy drug) to radiation can improve outcomes and be safe for people with early triple-negative breast cancer. It is designed for specific early-stage cases after breast surgery, using tumor and blood tests to match the cancer’s features.
Nanchang, JiangxiAges 18–75 - NCT04523857RecruitingPhase 2
Abemaciclib and hydroxychloroquine after breast cancer relapse risk
This Phase 2 trial tests whether abemaciclib plus hydroxychloroquine can kill tiny “leftover” cancer cells in the bone marrow after standard breast cancer treatment. It may help lower the chance of cancer coming back by targeting minimal residual disease.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04529044RecruitingPhase 2
177Lu-DOTATATE for advanced breast cancer with targeted receptors
This Phase 2 trial tests whether 177Lu-DOTATATE can slow or shrink stage IV or recurrent breast cancer. It targets tumor “receptors” found on scans, using a radioactive medicine that delivers radiation directly to cancer cells.
Portland, OregonAges 18–100 - NCT04553770RecruitingPhase 2
Trastuzumab deruxtecan with or without anastrozole for early breast cancer
This Phase 2 study tests whether trastuzumab deruxtecan alone or combined with anastrozole can control early-stage breast cancer that is HER2-low and hormone-receptor positive. It aims to improve outcomes after initial surgical treatment by targeting cancer cells that may have low levels of HER2.
Fullerton, CaliforniaAges 18 years+ - NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers
This early-phase study tests PC14586 (rezatapopt) in people with advanced or metastatic solid cancers that carry a specific TP53 mutation called Y220C. It mainly looks at safety and how well the treatment may work, sometimes combined with pembrolizumab.
Irvine, CaliforniaAges 12 years+ - NCT04606446RecruitingPhase 2
Study drug for ER-positive, HER2-negative cancers after treatment

You may qualify if you have a specific tumor type and a limited number of prior cancer treatments, and if your body functions (blood, liver, kidneys) and heart rhythm meet safety limits.
Scottsdale, ArizonaAges 18 years+ - NCT04660435Recruiting
Study how breast cancers resist CDK4/6 inhibitor treatment
This study looks at why some ER-positive, HER2-negative metastatic breast cancers don’t respond well to CDK4/6 inhibitors combined with hormone therapy. It may help researchers understand resistance and improve future treatment choices for people like you.
Prato, TuscanyAges Any age - NCT04683679RecruitingPhase 2
Radiation plus pembrolizumab and olaparib for certain breast cancers
This study tests whether adding the drugs pembrolizumab and olaparib (or similar “radiosensitizers”) to radiation can improve outcomes for women with advanced breast cancer that is triple-negative or ER-positive/Her2-negative. It’s designed for cancers that have spread or come back and where radiation is being considered to control disease.
Basking Ridge, New JerseyAges 18 years+ - NCT04698252RecruitingPhase 2
Local treatment for ER/PR-positive limited spread breast cancer
This Phase 2 study tests whether treating a small number of metastatic spots with a local approach (like targeted radiation, surgery, or ablation) can help people with ER/PR-positive breast cancer. It aims to help when the cancer has spread only to a few areas and has not significantly worsened after initial whole-body treatment.
São Paulo, São PauloAges 18 years+ - NCT04722978RecruitingPhase 3
Chemo plus moxifloxacin for metastatic triple-negative breast cancer
This trial tests whether adding moxifloxacin (an antibiotic) to standard chemotherapy helps people with metastatic triple-negative breast cancer live longer or respond better. You may qualify if your cancer has the right lab markers and you haven’t had treatment for metastatic disease yet.
Guangzhou, GuangdongAges 18–70 - NCT04874064Recruiting
AI blood tests for triple-negative breast cancer after treatment
This study uses a computer (AI) to read results from blood tests to look for signs of remaining triple-negative breast cancer, before and/or after surgery. It may help doctors better detect residual tumor and guide follow-up care.
