Weston, FloridaAges 18 years+ - NCT05616988Recruiting
Study body-image improvement after breast cancer surgery
This study looks at how body image changes after mastectomy and breast reconstruction, and whether certain body chemistry patterns (called metabolomics) are linked to that change. It may help researchers understand what supports better body-image recovery after breast cancer.
Rome, RomeAges 18 years+ - NCT05693766RecruitingPhase 2
Gene test guides treatment for hormone-positive breast cancer
This trial studies whether a gene-signature test can help guide treatment choices for people with hormone receptor–positive (ER and/or PR) breast cancer that has spread or can’t be fully removed. It may help find the best therapy approach after prior hormone therapy and targeted cancer medicine.
Birmingham, AlabamaAges 18 years+ - NCT05695313RecruitingPhase 2
Prevent nerve damage during weekly paclitaxel breast cancer treatment
This Phase 2 study tests whether a daily tablet (Onlife) can help prevent nerve side effects (“neurotoxicity”) caused by weekly paclitaxel given for breast cancer. You’d be randomly assigned to the tablet or a placebo, and you would be closely followed with questionnaires and clinic visits.
DijonAges 1.5 years+ - NCT05704166RecruitingPhase 2
Pirfenidone to prevent lung injury after breast radiation
This trial tests whether pirfenidone, a medication, can prevent acute lung injury caused by radiation therapy in people with breast cancer. You may be randomly assigned to pirfenidone or a placebo (inactive pill) to see which better protects the lungs during and after radiation.
Fuzhou, FujianAges 18–75 - NCT05725265Recruiting
Low-level laser treatment for arm swelling after breast cancer
This study tests whether low-level laser therapy can safely reduce swelling in one arm caused by breast-cancer treatment. It compares the laser to a look-alike inactive (placebo) treatment and checks changes over time.
TaipeiAges 20 years+ - NCT05739591Recruiting
Long-term follow-up for people treated in a breast cancer trial
This study checks how well a previous early breast cancer treatment works over the long term and monitors safety. It may help you and future patients by providing long-term results from the original trial.
InnsbruckAges 18 years+ - NCT05740787Recruiting
Study of thinking changes after chemotherapy for breast cancer
This study looks at how chemotherapy may affect thinking and memory in people with HER2-negative breast cancer. It uses brain scans during or after chemotherapy to understand these changes and potentially guide support in the future.
AberdeenAges 18 years+ - NCT05749588RecruitingPhase 2
Study for advanced triple-negative breast cancer after prior treatments
This Phase 2 trial tests a treatment for people with triple-negative breast cancer that has come back or spread and has continued to progress despite earlier therapies. It may help by trying a new approach in patients who still have enough health to safely receive more treatment.
ShanghaiAges 18 years+ - NCT05760378RecruitingPhase 3
Famitinib plus immunotherapy for advanced triple-negative breast cancer
This Phase 3 trial tests a combination of famitinib (a cancer drug that targets blood vessel growth) with immunotherapy drugs in people with newly diagnosed advanced triple-negative breast cancer that has spread or cannot be fully removed. It aims to improve how long patients live and how well the cancer responds.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05768139RecruitingPhase 1/Phase 2
Testing a new targeted drug for advanced solid tumors with PI3Kα mutation
This trial tests tersolisib, a new targeted medicine, in adults with advanced or hard-to-remove solid cancers. It focuses on tumors that have a specific genetic change (PI3Kα mutation) to see how well the treatment works and what side effects it causes.
Los Angeles, CaliforniaAges 18 years+ - NCT05776147Recruiting
Review of extreme breast radiation schedules in Brazil
This study looks back at medical records to understand outcomes when breast cancer patients get a very short course of radiation after surgery. It may help doctors learn whether this “extreme hypofractionation” schedule is safe and effective for more patients.
Fortaleza, CearáAges 18 years+ - NCT05782686Recruiting
Shaving wound skin regularly after breast-conserving surgery
This study looks at whether regularly removing (shaving) small amounts of skin during recovery can improve surgical healing and outcomes. It focuses on people having breast-conserving surgery for certain early breast cancers.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,469 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.
