Recruiting studies
- NCT07236177RecruitingEarly Phase 1
Enzyme test for early breast, lung, or pancreatic cancer
This study tests a new blood test that measures enzyme activity to detect localized cancer. It is for people with newly diagnosed, untreated breast, lung, or pancreatic cancer, as well as healthy volunteers.
PoitiersAges 18 years+ - NCT07558733RecruitingPhase 1/Phase 2
New drug combinations for advanced hormone-receptor positive breast cancer
This trial tests two new drugs (sapanisertib and serabelisib) alone or together to treat advanced breast cancer that is hormone-receptor positive. These drugs target specific pathways that help cancer grow, and the trial will see if they work better than standard treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT07281976RecruitingPhase 1/Phase 2
LBL-024 for triple negative breast cancer
This trial tests a new drug called LBL-024, either alone or with other medicines, for people with triple negative breast cancer. It aims to see if the drug can shrink tumors and how safe it is.
Guangzhou, GuangdongAges 18 years+ - NCT07314073RecruitingPhase 2
A PET scan to find hidden spread in slow-growing breast cancer
This trial is testing a special PET scan (18F-FES PET/CT) to see if it can find distant cancer spread in women with a slow-growing, estrogen receptor-positive, stage III breast cancer. The goal is to find out whether this imaging test can detect hidden metastases better than standard scans.
SeoulAges 19 years+ - NCT07326800Recruiting
Meditation and values program for breast cancer patients
This trial tests a program called MAEva that combines meditation and acceptance techniques to help patients with non-metastatic breast cancer. It aims to improve well-being by focusing on personal values and coping skills.
Vandœuvre-lès-NancyAges 18 years+ - NCT07342283RecruitingPhase 2
QL1706 plus chemo before surgery for triple-negative breast cancer
This trial tests a combination of an immunotherapy drug (QL1706) plus standard chemotherapy given before surgery to shrink triple-negative breast cancer. The goal is to see if this approach helps remove the tumor more completely.
Nantong, JiangsuAges 18 years+ - NCT07394387RecruitingPhase 2
HIFU with or without immunotherapy before chemo for triple-negative breast cancer
This trial tests whether adding focused ultrasound (HIFU) and an immunotherapy drug (PD-1 inhibitor) before standard chemotherapy can improve outcomes for women with stage II or III triple-negative breast cancer (TNBC). It aims to find a more effective way to shrink tumors before surgery.
Nanjing, JiangsuAges 18–70 - NCT01788839Recruiting
Long-term health and fertility study for women with breast cancer
This study follows women with breast cancer and certain lymphomas to understand long-term sexual and reproductive health. It may help researchers better support patients’ body changes and wellness over time during and after treatment.
Basking Ridge, New JerseyAges 18 years+ - NCT07418125Recruiting
Study of tumor cell clusters in high-risk early breast cancer
This trial looks at whether clusters of tumor cells in the blood can give more information about high-risk early breast cancer. It is for people with certain types of breast cancer who are about to start treatment before surgery (neoadjuvant therapy).
LjubljanaAges 18 years+ - NCT07436312Recruiting
Effect of ultra-processed foods on cancer risk in high-risk people
This trial looks at whether eating less ultra-processed foods can lower cancer risk in people who are already at high risk for cancer. It is part of a larger program called Interception that helps monitor and reduce cancer risk.
AvignonAges 18 years+ - NCT07513311Recruiting
Nurse Support Program for Triple-Negative Breast Cancer
This study tests a nurse-led coping and support program for people who recently finished treatment for triple-negative breast cancer. The program is designed to help you manage stress and emotional distress after treatment.
Boston, MassachusettsAges 18 years+ - NCT05019690RecruitingPhase 1/Phase 2
Test drug combo for advanced triple-negative breast cancer
This trial studies how well apatinib plus albumin-bound paclitaxel works for advanced triple-negative breast cancer that has come back or spread. It may help shrink tumors and control the disease by targeting cancer growth in more than one way.
Fuzhou, FujianAges 18–75 - NCT06470347RecruitingPhase 1/Phase 2
Testing Pyrrolitinib After Trastuzumab for HER2+ Breast Cancer
This study tests if taking pyrrolitinib (a targeted medicine) can further reduce the risk of breast cancer returning in patients with HER2-positive early breast cancer who have already received trastuzumab after surgery.
Zunyi, GuizhouAges 18–75 - NCT06910657RecruitingPhase 1
IDOV-Immune vaccine for advanced solid tumors
This trial tests an experimental virus-based treatment for people with advanced solid tumors that have stopped responding to standard therapies. The treatment is designed to infect and destroy cancer cells while boosting the immune system.
St Louis, MissouriAges 18 years+ - NCT07264985Recruiting
Gut bacteria and diarrhea in breast cancer patients on pyrotinib
This study looks at how gut bacteria relate to diarrhea in breast cancer patients who are taking a drug called pyrotinib. By understanding this link, doctors hope to better manage side effects in the future.
Wuhan, HubeiAges 18–75 - NCT04159818RecruitingPhase 2
Adding immune treatments to improve checkpoint drug response in TNBC
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+ - NCT05000294RecruitingPhase 1/Phase 2
Atezolizumab plus tivozanib for hard-to-treat “cold” cancers
This early-stage study tests whether combining atezolizumab and tivozanib can shrink advanced, hard-to-treat cancers that do not strongly activate the immune system (“immunologically cold”). It is for people whose cancer has already been treated or has no good standard options.
Gainesville, FloridaAges 18–99 - NCT05130801RecruitingPhase 1/Phase 2
MRI and pHLIP dye during breast surgery to map tumors
This trial tests whether a special MRI and an injected light-activated dye (pHLIP® ICG) can help doctors see and target breast cancer during surgery. You may be offered this approach around the time of breast-conserving surgery, to improve how well the tumor area is identified.
Montvale, New JerseyAges 18 years+ - NCT06043466RecruitingPhase 1
CAR-T cell therapy for CEA-positive advanced solid tumors
This trial tests a new cell therapy called CAR-T that targets cancer cells with a protein called CEA. It is for people with certain advanced cancers that have not responded to standard treatments.
Hangzhou, ZhejiangAges 18 years+ - NCT06053086Recruiting
Adaptive radiation therapy for breast cancer patients at high risk
This trial tests a new way to deliver radiation therapy that adapts to each patient's body changes during treatment. It is for women who had breast cancer surgery and need radiation to the whole breast and nearby lymph nodes, and who have been identified as being at risk for breast fibrosis.
MontpellierAges 18 years+ - NCT06337084RecruitingPhase 1

Testing AGX101 for advanced solid tumors
This study tests a new drug called AGX101 for people with advanced solid tumors that have not responded to other treatments. The goal is to see if it is safe and if it can shrink tumors or slow their growth.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,460 recruiting breast cancer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a breast cancer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a breast cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
