Study of two targeted therapies before surgery for HER2+ breast cancer
This trial tests a combination of two drugs, trastuzumab deruxtecan (SHR-A1811) and pertuzumab, given before surgery to shrink HER2-positive breast cancer. It is for women with stage II or III breast cancer who have not yet had treatment and are in good overall health.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07380971Recruiting
Exercise program for breast cancer patients
This trial is testing a supervised exercise program designed for women with breast cancer. The goal is to see if it helps improve recovery and overall well-being during and after treatment.
Madrid, MadridAges 18 years+ - NCT04990921RecruitingPhase 2
Palliative radiation plus pembrolizumab for metastatic breast cancer
This trial studies whether adding a focused, comfort-focused form of radiation (SBRT) to pembrolizumab can help people with stage IV breast cancer that cannot be removed with surgery. You may be eligible if you can receive palliative SBRT and have measurable tumors, and if you meet prior-therapy and blood/health criteria.
Louisville, KentuckyAges 18 years+ - NCT07383818RecruitingPhase 2
Neoadjuvant therapy with trastuzumab rezetecan and toripalimab for HR+/HER2-low breast cancer
This trial tests a combination of two drugs (trastuzumab rezetecan and toripalimab) given before surgery to treat a specific type of breast cancer that is hormone-receptor-positive and HER2-low. It aims to see if this treatment can improve outcomes for patients who have not had prior cancer treatment.
HarbinAges 18–70 - NCT07377279Recruiting
Acupuncture and compression to prevent nerve pain from chemo
This trial tests whether acupuncture and compression therapy can prevent nerve damage caused by taxane chemotherapy in early-stage breast cancer. It aims to reduce numbness, tingling, or pain in the hands and feet.
Guangzhou, GuangdongAges 18–70 - NCT07327021RecruitingPhase 2
MRI-Guided treatment reduction for stage 2-3 triple-negative breast cancer
This trial tests if using MRI scans can safely reduce the amount of chemotherapy and immunotherapy needed before surgery for triple-negative breast cancer. All patients will receive the standard KEYNOTE-522 regimen, but the treatment may be tailored based on MRI results.
Tel AvivAges 18 years+ - NCT05968677Recruiting
Amino acids and flavonoids to reduce chemotherapy side effects
This trial tests whether a specific nutrition supplement (amino acids and flavonoids) can lessen chemotherapy side effects, support nutrition, and improve quality of life in people with non-metastatic breast cancer. It focuses on women who are receiving certain chemotherapy medicines and can eat by mouth and attend regular visits.
PaviaAges 50–70 - NCT07295457Recruiting
Exercise to prevent pain from hormone therapy in breast cancer
This trial tests whether starting a gentle exercise program early can help prevent or reduce joint and muscle pain caused by aromatase inhibitors (a common breast cancer medicine). It is for women with hormone-sensitive breast cancer who are not yet experiencing severe pain from their treatment.

- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,414 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.
