Trastuzumab deruxtecan for HER2-low metastatic breast cancer
This trial tests a targeted antibody-drug medicine (trastuzumab deruxtecan, T-DXd) in people with metastatic breast cancer that is HER2-low or HER2 IHC 0. It may help by treating tumors that haven’t previously received anti-HER2 treatment in the metastatic setting.

Better HER2 testing for HER2-low breast cancer on Enhertu
This study looks at using a more detailed lab test to measure HER2 levels in people with HER2-low metastatic breast cancer who are starting or have just started treatment with Enhertu. The goal is to see if this test can help doctors better understand who might benefit from Enhertu.
San Francisco, CaliforniaAges 18 years+ - NCT06518382Recruiting
Study of leftover tumor after chemo and trastuzumab
This study looks at leftover breast cancer cells (after chemo and targeted therapy) to find out why some cells resist treatment. It may help doctors better understand how to treat HER2-positive breast cancer in the future.

Trastuzumab-deruxtecan before surgery for HER2-positive early breast cancer
This trial compares giving trastuzumab-deruxtecan before surgery versus standard chemotherapy plus trastuzumab and pertuzumab. It aims to see which approach works better to shrink or control HER2-positive early breast cancer and improve outcomes.
Baden-Baden, Baden-WurttembergAges 18 years+ - NCT06650332RecruitingPhase 1/Phase 2
Cadonilimab combo for first-line HER2-positive gastric cancer
This trial tests a new combination treatment (cadonilimab plus chemotherapy) as the first therapy for people with advanced gastric or gastroesophageal junction cancer that has a certain amount of HER2 protein. It aims to see if this combination can shrink tumors and help people live longer.
Hangzhou, ZhejiangAges 18–75 - NCT07294508RecruitingPhase 2/Phase 3
Testing a new drug combo for HER2-positive advanced breast cancer
This trial tests two study drugs, HLX22 and HLX87, together for people with HER2-positive breast cancer that has spread or come back. It may be an option if you haven't yet had chemotherapy or HER2-targeted therapy for advanced disease.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06450873RecruitingPhase 2
Turkey tail mushroom before breast cancer surgery

Common questions
- Are there clinical trials for her2 positive?
- Yes. Clin2 currently lists 345 recruiting her2 positive 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 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 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.
