- NCT07111832RecruitingPhase 3
Study of SHR-A1811 for triple-negative breast cancer
This study tests a new drug called SHR-A1811 for people with triple-negative breast cancer that has spread or come back. It looks at whether the drug can help shrink tumors or slow the cancer's growth.
Beijing, Beijing MunicipalityAges 18–75 - NCT04799535Recruiting

Birmingham, AlabamaAges 18–75 - NCT05576389RecruitingPhase 2
Fluzoparib plus camrelizumab before surgery for BRCA-related HER2-negative breast cancer
This study tests a combination of two drugs – fluzoparib (a PARP inhibitor) and camrelizumab (an immunotherapy) – given before surgery for early-stage or locally advanced HER2-negative breast cancer in people with an inherited BRCA mutation. The goal is to see if this treatment can shrink the tumor and improve outcomes.

This trial tests if the drug dapagliflozin can prevent heart damage caused by anthracycline chemotherapy in breast cancer patients. It aims to see if taking the drug during chemo helps keep your heart healthy.
LjubljanaAges 18 years+ - NCT04481763RecruitingPhase 1/Phase 2
Camrelizumab plus radiation for early triple-negative breast cancer
This trial studies whether adding camrelizumab (an immunotherapy drug) to radiation can improve outcomes and be safe for people with early triple-negative breast cancer. It is designed for specific early-stage cases after breast surgery, using tumor and blood tests to match the cancer’s features.

Trop-2 drug combo for advanced triple-negative breast cancer
This trial tests a new drug combination (Trop-2 antibody-drug conjugate plus other therapies) for advanced triple-negative breast cancer that has spread or come back. It may offer a new option for people who have had only 1–2 prior chemotherapies and have not used immunotherapy or anti-angiogenic drugs before.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT07574749Recruiting
Breast Cancer Blood Test to Guide Treatment Choices
This study examines tiny particles in your blood from breast cancer cells to better predict which treatments will work best for you. Researchers will collect blood samples and a small tissue sample to understand your cancer's characteristics and help doctors choose more effective therapy.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05326295Recruiting
Breast cancer study using tumor cells in blood
This trial checks whether a blood test that looks at tumor cells can help guide treatment for people with breast cancer. If you join, your care team will follow your responses over time to see if this “phenotype surveillance” approach is useful.
Changsha, HunanAges 18–75 - NCT06791161Enrolling by invitation
Adjuvant therapy study for BRCA1/2 positive breast cancer
This study tests if additional treatment after surgery helps prevent breast cancer from returning. It is for people with hormone receptor-positive, HER2-negative breast cancer who have a BRCA1 or BRCA2 gene mutation and a high risk of recurrence.
Beijing, Beijing MunicipalityAges 18–75 - NCT05939830Recruiting
Skipping axillary lymph node surgery after treatment response
This study looks at whether some breast cancer patients can safely skip a surgery that removes lymph nodes in the armpit after their initial (pre-surgery) treatment shows the armpit is likely clear. It may reduce surgical side effects if the armpit truly responds well.
NanjingAges 18–70 - NCT07525869Recruiting
Pegfilgrastim to prevent low white blood cells in triple-negative breast cancer
This study tests whether a medicine called pegfilgrastim can help prevent dangerously low white blood cell counts in women with triple-negative breast cancer receiving a specific chemotherapy combination. Low white blood cells increase infection risk, so this medicine may help patients stay safer during treatment.
Seoul, Seodaemun-guAges 19–70 - NCT03265379Recruiting
Registry study for breast cancer invading the chest wall
This study follows people with breast cancer that has spread into the chest wall who are planning full-thickness chest wall surgery. It aims to improve quality of life by collecting real-world information during and after treatment.

This trial is testing a combination of two targeted therapies, SKB264 and Inetetamab, for people with advanced HER2-positive breast cancer that has kept growing after treatment with T-DXd and other HER2-targeted therapies. The goal is to see if this new combination can shrink tumors or slow the cancer's growth.
ShanghaiAges 18 years+ - NCT06417801Recruiting

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,474 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.
