SantiagoAges 60 years+ - NCT05649072Recruiting
Mobile mammogram screening study for women with family cancer risk
This study looks at how well mobile mammogram units and video/phone genetics counseling (“telegenetics”) can help women who may have inherited cancer risk. If you’re scheduled for a mammogram through the Project VALET mobile units, this may be an easy option to learn about and address your risk.
Houston, TexasAges 18 years+ - NCT07085442Recruiting
Audit of targeted sentinel node biopsy in early breast cancer
This study is checking how well a special type of lymph node biopsy (targeted sentinel node biopsy) works for people with early-stage breast cancer that has spread to just a few lymph nodes. If you are planning breast surgery and meet the specific criteria, this audit will review your results to help improve future care.
BurnleyAges 18 years+ - NCT07227077Recruiting

This study uses a smartphone program to encourage physical activity in older adults who have survived cancer and have ongoing pain. It aims to learn how to best help you move more and feel better.
Milwaukee, WisconsinAges 65 years+ - NCT06771609RecruitingPhase 2
Immunotherapy plus low-dose chemo for advanced triple-negative breast cancer
This study tests a combination of an immunotherapy drug (PD-L1 inhibitor) with a special low-dose chemotherapy regimen (VEX) plus optional radiation for advanced triple-negative breast cancer. The goal is to see if this approach works better than standard treatments.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05544240RecruitingPhase 1
First-in-human immunotherapy study for advanced solid tumors
This Phase 1 trial tests SYNC-T, an immunotherapy, in people with advanced or metastatic solid cancers. It aims to find the safest dose and see whether the treatment can shrink or control tumors.
Mexico CityAges 18 years+ - NCT06715020Recruiting
Testing a new imaging method for breast cancer treatment
This study uses a special scan (molecular imaging) to see how well antibody-drug conjugates (ADCs) work in people with breast cancer. It may help doctors choose the right treatment for you.
BeijingAges 18–75 - NCT07189871RecruitingPhase 1/Phase 2
177Lu-BetaBart for advanced solid tumors
This trial tests a new radioactive drug, 177Lu-BetaBart, for people with certain advanced solid tumors that have stopped responding to other treatments. The goal is to see if it can shrink tumors or slow their growth.
Dothan, AlabamaAges 18 years+ - NCT05433753Recruiting
Study for leftover cancer DNA in HER2-positive early breast cancer
This study looks for tiny traces of cancer after treatment by testing blood for “ctDNA,” which is leftover cancer DNA. It includes people with HER2-positive early breast cancer who are getting chemotherapy before surgery to see if this blood test can detect signs of remaining disease.
Chuo-ku, TokyoAges 20 years+ - NCT04333706RecruitingPhase 1/Phase 2
Sarilumab plus capecitabine for certain breast cancers
This trial studies whether adding sarilumab to capecitabine can shrink or control metastatic or high-risk breast cancer that lacks HER2 and is either triple-negative or hormone-resistant. It aims to find a safe dose first, then look at how well the treatment works compared with historical results.
Los Angeles, CaliforniaAges 18–99 - NCT06784193RecruitingPhase 1
Study of OP-3136 for advanced solid tumors
This trial tests a new drug, OP-3136, alone or with other drugs, for people with advanced breast cancer, prostate cancer, or lung cancer that has stopped responding to other treatments. It aims to see if OP-3136 is safe and effective.

Skipping breast surgery for some patients after chemo
This trial tests whether women with certain aggressive breast cancers (HER2-positive without hormone receptors, or triple-negative) can safely skip breast surgery if chemotherapy makes their tumor completely disappear. The goal is to avoid surgery and its side effects when it may no longer be needed.
TianjinAges 18–70 - NCT03643861Recruiting
Radiation after lumpectomy for certain early breast cancers

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.
