BeijingAges 18–75 - NCT07233499RecruitingPhase 2
Nebivolol for heart protection during breast cancer treatment
This trial tests if the drug nebivolol can protect the heart from damage caused by trastuzumab (Herceptin) in women with HER2-positive breast cancer. If effective, it may help prevent heart problems while still allowing cancer treatment.
CairoAges 18–65 - NCT07237256RecruitingPhase 3
Testing less chemo for HR+ HER2- breast cancer with ribociclib
This trial tests whether some people with hormone receptor-positive, HER2-negative early breast cancer can safely receive less chemotherapy when also taking the targeted drug ribociclib after surgery. You may qualify if you have a specific stage of breast cancer and are planning to take hormone therapy for at least 5 years.

Benevento, BeneventoAges 18 years+ - NCT00437879Recruiting
Ultrasound and MRI scans to track breast cancer response early
This study uses ultrasound and/or MRI scans to see how breast cancer responds early while you start “neoadjuvant” treatment (chemotherapy, with or without radiation before surgery). It may help doctors spot response sooner and better understand which imaging changes match treatment benefit.
Toronto, OntarioAges Any age - NCT02422641RecruitingPhase 2
High-dose methotrexate for breast cancer in the brain lining
This Phase 2 trial tests whether giving high-dose methotrexate into the bloodstream can help treat breast cancer that has spread to the thin lining covering the brain and spinal cord. It may help reduce cancer in the leptomeningeal (brain-lining) area and control symptoms.

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.
