TM plus capecitabine for triple-negative breast cancer
This trial tests a drug called tetrathiomolybdate (TM) combined with capecitabine for people with triple-negative breast cancer who still have cancer cells after standard chemotherapy and surgery. The goal is to see if this combination can help prevent the cancer from coming back.
Indianapolis, IndianaAges 18–80 - NCT06139107RecruitingPhase 1
Radiation and abemaciclib plus letrozole before breast cancer surgery
This trial combines a short course of radiation before surgery with two oral medications (abemaciclib and letrozole) to treat early-stage, hormone-sensitive breast cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
Belleville, New JerseyAges 60 years+ - NCT06165900RecruitingPhase 2
Radiation plus immunotherapy and chemo before surgery for triple-negative breast cancer
This trial tests combining stereotactic radiation therapy with immunotherapy (adebrelimab) and chemotherapy (nab-paclitaxel and carboplatin) before surgery for early or locally advanced triple-negative breast cancer. The goal is to see if this combination improves treatment response.
Shenyang, LiaoningAges 18–75 - NCT06200168RecruitingPhase 3
Electroacupuncture to prevent nausea during breast cancer chemo
This study tests whether electroacupuncture can help prevent nausea and vomiting caused by strong chemotherapy in people with breast cancer. If you're starting a certain type of chemo, this could help you feel better during treatment.
Xining, QinghaiAges 18–75 - NCT06214598Recruiting
Anti-inflammatory diet for breast cancer patients on hormone therapy
This study tests whether a special anti-inflammatory diet can help reduce side effects in breast cancer survivors who are taking aromatase inhibitors after menopause. You would be randomly assigned to either follow the diet for 6 months or continue your usual diet, and your health will be monitored.
BelgradeAges 45–70 - NCT06222957Recruiting
How HER2 affects brown fat in breast cancer patients
This study looks at how a protein called HER2 affects brown fat activity in women with breast cancer. Brown fat helps burn calories and may influence treatment outcomes. You will be assigned to one of two groups based on your cancer's HER2 status, and the study will measure how your brown fat responds to cold.
CopenhagenAges 18 years+ - NCT06230185Recruiting
Blood test to monitor treatment response in triple-negative breast cancer
This trial is testing whether a blood test can track how well chemotherapy is working in people with early-stage triple-negative breast cancer. You would provide blood samples before and during treatment, and the results may help your doctor understand your response better.
Tucson, ArizonaAges 18 years+ - NCT06252662RecruitingPhase 4
Comparing two numbing medicines for mastectomy nerve blocks
This study compares two types of numbing medicine given through a nerve block before a mastectomy. One is a long-acting version (liposomal bupivacaine) and the other is a standard numbing medicine combined with a sedative (bupivacaine with dexmedetomidine). The goal is to see which provides better pain relief after surgery.
Portsmouth, VirginiaAges 18 years+ - NCT06258993Recruiting

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,470 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.
