Shenzhen, GuangdongAges 18–75 - NCT07503717Recruiting
Brain scan surveillance in HER2-positive metastatic breast cancer
This study tests whether regular brain scans (surveillance) help spot brain metastases early in people with HER2-positive breast cancer that has spread to other parts of the body. Participation involves being randomly assigned to either routine brain scans or no extra scans to see which approach is better.

Shenzhen, GuangdongAges 18–75 - NCT07542496Recruiting
Real-world study of breast cancer treatment with pertuzumab biosimilar
This study observes how a biosimilar version of pertuzumab (a targeted breast cancer drug) works in real-world patients. Researchers will track outcomes in patients receiving this drug either before surgery or as a first treatment for advanced breast cancer.
AlgiersAges 19 years+ - NCT07610720RecruitingPhase 2
Dalpiciclib With Anti-HER2 and Hormone Therapy for Advanced Breast Cancer
This trial tests a combination of three drugs—dalpiciclib (a new cell-cycle inhibitor), anti-HER2 therapy, and hormone therapy—for advanced breast cancer that is positive for both hormone receptors and HER2 protein. The goal is to help patients whose cancer has responded to initial treatment stay in remission longer.
Guangdong, GUANGZHOUAges 18–75 - NCT07615751RecruitingPhase 3
New drug combination for advanced HER2-positive breast cancer
This trial tests whether a newer drug called dalpiciclib works better than chemotherapy when combined with two other anti-HER2 drugs (pyrotinib and trastuzumab) for advanced breast cancer that has spread. The goal is to find a treatment that works well with fewer side effects.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07647263RecruitingPhase 2
New Drug Treatment Before Surgery for HER2-Positive Breast Cancer
This trial tests a new drug called trastuzumab rezetecan given before surgery for early-stage HER2-positive breast cancer. It's designed for patients whose cancer doesn't respond well to standard HER2-targeted treatments.
Suzhou, JiangsuAges 18 years+ - NCT07666555RecruitingPhase 2
Culmerciclib rechallenge for HR+ HER2- breast cancer
This trial tests a new drug called Culmerciclib for women with advanced HR-positive, HER2-negative breast cancer that has stopped responding to a CDK4/6 inhibitor with hormone therapy. The goal is to see if giving this drug again can help when other treatments no longer work.
ShanghaiAges 18–75 - NCT07292571Enrolling by invitationPhase 2
Tracing breast cancer HER2 with a special scan
This study uses a radioactive tracer to see how much HER2 protein is on your breast cancer cells. The scan may help doctors understand the type of HER2 you have and choose the best treatment.
TomskAges 18–80 - NCT07023861Enrolling by invitationEarly Phase 1
New imaging test for HER2-positive cancers
This trial tests a new imaging method that uses a radioactive tracer to find HER2-positive cancer cells in the body. It may help doctors see tumors more clearly in people with stomach, breast, or bladder cancer.
Wuxi, JiangsuAges 15–75 - NCT06843681Enrolling by invitationPhase 2
Trastuzumab and Chemo Before Surgery for HER2-Positive DCIS
This trial tests giving trastuzumab (a targeted drug) plus a chemotherapy drug called a taxane before surgery for women with HER2-positive ductal carcinoma in situ (DCIS), an early form of breast cancer. The goal is to see if this combination can shrink or eliminate the cancer before surgery.
Guangzhou, GuangdongAges 18–70 - NCT07007169RecruitingPhase 2
Mediterranean diet study for early breast cancer
This trial tests whether eating a Mediterranean-style diet (rich in vegetables, fruits, whole grains, and healthy fats) can help improve outcomes for women with early breast cancer who are receiving chemotherapy. You will be asked to follow this diet and keep a food diary using an online tool.
EsbjergAges 18 years+ - NCT07049133Recruiting
Tracking side effects of T-DXd for advanced breast cancer

- Yes. Clin2 currently lists 242 recruiting her2-positive 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 her2-positive 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 her2-positive 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.
