Recruiting studies
- NCT04997993RecruitingPhase 1
Leflunomide for PTEN-altered or HER2-negative metastatic cancers
This Phase 1 trial studies whether leflunomide can slow or control advanced (metastatic) cancers in people whose tumors have specific PTEN changes or who have HER2-negative breast cancer. It’s primarily a safety-and-dosing study, but it may offer benefit if your cancer matches the tumor marker requirements.
New York, New YorkAges 18 years+ - NCT06857305Enrolling by invitationPhase 3
Eribulin every two weeks vs standard schedule for advanced breast cancer
This trial compares a new every-two-week dosing schedule of the chemotherapy drug eribulin to the standard schedule in people with HER2-negative breast cancer that has returned or spread. The goal is to see if the biweekly regimen is safer or works better.
Beijing, BAges 18 years+ - NCT07263425RecruitingPhase 2
Study of thiotepa and trastuzumab for breast cancer that spread to the lining of the brain and spinal cord
This trial tests a combination of two drugs given through a special port in the head to treat HER2-positive breast cancer that has spread to the layer covering the brain and spinal cord (leptomeningeal metastasis). It aims to see if this treatment is safe and effective.
Nanjing, JiangsuAges 18–75 - NCT07739485RecruitingPhase 1/Phase 2
Oral paclitaxel before surgery for triple-negative breast cancer
This trial tests an oral form of a common chemo drug, paclitaxel, given before surgery for triple-negative breast cancer. It aims to find the best dose and see how well it shrinks tumors.
Guiyang, GuizhouAges 18–70 - NCT07648914RecruitingPhase 3
BL-B01D1 versus chemotherapy for advanced hormone-receptor-positive breast cancer
This trial tests a new targeted drug called BL-B01D1 against standard chemotherapy in patients with advanced breast cancer that is hormone-receptor-positive (HR+) and HER2-negative, and has stopped responding to hormone treatments. The goal is to see if the new drug works better or has fewer side effects.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04437160RecruitingPhase 2
Chemo after surgery for triple-negative breast cancer with leftover tumor
This Phase 2 study tests chemotherapy given after surgery for people with triple-negative breast cancer who still have cancer left after initial (neoadjuvant) chemo. It may help lower the chance the cancer comes back in people at higher risk based on leftover tumor and lymph node findings.
Beijing, Beijing MunicipalityAges 18–75 - NCT05582538RecruitingPhase 2
Ceralasertib plus immunotherapy for advanced triple-negative breast cancer
This Phase 2 trial tests whether a drug called ceralasertib can help the immune system work better, followed by durvalumab plus nab-paclitaxel. It is for people with advanced triple-negative breast cancer whose cancer returned after earlier treatment, including chemotherapy and immune therapy.
Novara, NovaraAges 18 years+ - NCT06915168Recruiting
Nerve symptom decision aid for breast cancer patients
This study tests a decision aid tool that helps people with breast cancer and nerve-related side effects from chemotherapy (like numbness or tingling) make better choices about their treatment. If you're on your third round of taxane chemo and have these symptoms, this tool may help you talk with your doctor.
Ann Arbor, MichiganAges Any age - NCT07034976Recruiting
Radiofrequency treatment for menopause symptoms in breast cancer survivors
This trial tests a non-surgical radiofrequency treatment, combined with pelvic floor exercises, to help with vaginal dryness and other menopause symptoms in breast cancer survivors. It may be an option if you are free of cancer and have bothersome vaginal dryness.
Madrid, MadridAges 18–75 - NCT07354022RecruitingPhase 3
Study of HRS-8080 with dalpiciclib for advanced breast cancer after hormone therapy fails
This trial tests a new combination of drugs (HRS-8080 and dalpiciclib) for women with advanced or metastatic breast cancer that has stopped responding to initial hormone therapy after surgery. It aims to see if this combination is safe and effective.
Beijing, Beijing MunicipalityAges 18–75 - NCT07666555RecruitingPhase 2
Culmerciclib rechallenge for HR+ HER2- breast cancer
This trial tests a new drug called Culmerciclib for women with advanced HR-positive, HER2-negative breast cancer that has stopped responding to a CDK4/6 inhibitor with hormone therapy. The goal is to see if giving this drug again can help when other treatments no longer work.
ShanghaiAges 18–75 - NCT07672392Recruiting
Exercise after breast reconstruction surgery
This trial tests whether a structured exercise program after DIEP flap breast reconstruction helps improve physical fitness compared to standard care. It may help women recover strength and well-being after surgery.
Beaumont, DublinAges 18 years+ - NCT07376681Enrolling by invitation
Fertility in young breast cancer patients
This study looks at fertility, cancer outcomes, and children's health in women diagnosed with breast cancer at age 40 or younger. It aims to help you understand how breast cancer and its treatment may affect your ability to have children and your long-term health.
Taizhou, ZhejiangAges 18–40 - NCT05386108RecruitingPhase 1/Phase 2
Test abemaciclib plus elacestrant for breast cancer brain spread
This trial studies whether the combination of abemaciclib and elacestrant can slow or shrink ER-positive, HER2-negative breast cancer that has spread to the brain. It is designed for people whose cancer has progressed despite prior hormone (endocrine) treatment.
Fullerton, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
Gilbert, ArizonaAges 18 years+ - NCT06839560RecruitingPhase 2
Immunotherapy plus chemotherapy and radiation for advanced breast cancer with brain metastases
This trial tests a combination of a PD-L1 inhibitor with a low-dose chemotherapy regimen and either immediate or delayed radiation therapy for people with HER2-negative breast cancer that has spread to the brain. The goal is to see if this approach helps shrink brain tumors and improve outcomes.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05974150Recruiting
Remote symptom monitoring for several blood and cancer types
This study checks how well remote (at-home) symptom check-ins work for people with certain cancers. It may help patients and clinicians spot problems earlier and improve day-to-day care during treatment and beyond.
New Haven, ConnecticutAges 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.
Zhengzhou, HenanAges 18 years+ - NCT07396454RecruitingPhase 2
Radiation plus anlotinib for HER2-negative breast cancer brain metastases

It aims to see if adding avasopasem can help control the cancer.
San Antonio, TexasAges 18 years+ - NCT06255392RecruitingPhase 3
Fluzoparib with apatinib vs chemo for advanced breast cancer
This trial tests a combination of two oral targeted drugs (fluzoparib and apatinib) against standard chemotherapy for women with advanced, HRD-positive, HER2-negative breast cancer. It may be an option if you have already received some treatments but not too many.
Guangzhou, GuangdongAges 18–70 - NCT04215003RecruitingPhase 1/Phase 2

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,472 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.
