Surgery chemotherapy plus anti-HER2 and anti–immune therapy for HER2 stomach cancer
This Phase 2 trial tests adding chemotherapy plus trastuzumab and toripalimab around the time of surgery for HER2-positive, locally advanced stomach or esophagus-stomach junction cancer. It aims to shrink the cancer and reduce the chance it comes back by attacking it through more than one pathway.
Hangzhou, ZhejiangAges 18–80 - NCT05305924RecruitingPhase 2
Fulvestrant plus abemaciclib for ER+, HER2− advanced breast cancer
This Phase 2 study tests whether adding abemaciclib to fulvestrant can slow or shrink ER-positive, HER2-negative metastatic breast cancer. It is mainly for people whose cancer has progressed despite prior treatment with a CDK4/6 inhibitor and an aromatase inhibitor.
Houston, TexasAges 18 years+ - NCT06949410RecruitingPhase 1
HER2 vaccine study for high-risk breast cancer
This trial tests a vaccine designed to help the immune system fight remaining HER2-positive breast cancer cells after standard treatment. It is for people who have completed at least six months of HER2-targeted therapy and still have a high risk of the cancer coming back.
Indianapolis, IndianaAges 18 years+ - NCT05467891RecruitingPhase 2
Ribociclib plus hormone therapy for recurrent breast cancer
This trial tests whether adding ribociclib (a targeted pill) to hormone therapy can control breast cancer that has come back in the breast area or nearby lymph nodes/chest wall. It targets hormone-receptor–positive and HER2-negative tumors to help slow disease after local treatment.
Birmingham, AlabamaAges 18 years+ - NCT05795101RecruitingPhase 2
TRUDI trial for inflammatory breast cancer with HER2/low markers
This Phase 2 trial tests two medicines—durvalumab and trastuzumab deruxtecan—to treat stage III inflammatory breast cancer. It may help by controlling cancer growth using treatments aimed at specific breast cancer markers (HER2 positive or “HER2-low”).
Boston, MassachusettsAges 18 years+ - NCT06065748RecruitingPhase 3
New hormone therapy for advanced breast cancer after prior treatment
This trial tests a new oral hormone therapy, giredestrant, against a standard hormone therapy (fulvestrant) when both are given with a CDK4/6 inhibitor. It is for people with advanced ER-positive, HER2-negative breast cancer that has come back after initial hormone therapy, and who have not yet had other treatments for advanced disease.

HER2 status in esophagogastric cancer and patient outcomes
This study looks back at medical records of people with a certain type of esophageal or stomach cancer to see how HER2 status relates to patient outcomes. It may help guide future treatment decisions.
Dublin, LeinsterAges Any age - NCT07600164RecruitingPhase 4
Real-world study of pyrotinib treatment for advanced HER2-positive breast cancer
This study follows patients with advanced breast cancer that has a protein called HER2 to see how well pyrotinib (a targeted drug) works when used in routine clinical practice. You'd be tracked over time to understand how this treatment affects your cancer and quality of life.

Pyrotinib, dalpiciclib, and letrozole for advanced breast cancer
This trial tests a combination of three targeted drugs for a type of advanced breast cancer that is both ER-positive and HER2-positive. The goal is to see if adding these two new drugs to standard hormone therapy can help shrink or control the cancer.
Hangzhou, ZhejiangAges 18–75 - NCT06179303RecruitingPhase 2
Imaging to predict response to abemaciclib for advanced breast cancer
This trial tests if a special PET scan can predict how well the drug abemaciclib works for people with advanced hormone receptor-positive, HER2-negative breast cancer. If you qualify, you would receive abemaciclib and have imaging scans to see if your cancer responds.
St Louis, MissouriAges 18 years+ - NCT06883487Recruiting
Exploring HER2 testing in high-grade ovarian cancer
This study looks at how to best detect the HER2 protein in high-grade serous ovarian cancer. The goal is to improve treatment choices for people with this type of cancer.
Guangzhou, GuangdongAges 18–75 - NCT05020860RecruitingPhase 2
Study how early breast cancer responds on imaging and under a microscope
This Phase 2 study looks at how well early breast cancer shrinks with treatment and how that matches with what doctors find after surgery under the microscope. The goal is to learn better ways to predict and assess treatment success.
Houston, TexasAges 18 years+ - NCT06439693RecruitingPhase 2
Sequential therapy for newly diagnosed HER2+ breast cancer that has spread
This trial tests a sequence of targeted therapies for people newly diagnosed with HER2-positive breast cancer that has spread to other parts of the body. The goal is to find a treatment plan that can potentially cure the cancer.
Boston, MassachusettsAges 18 years+ - NCT06754059Recruiting
Pyrotinib with trastuzumab for HER2-positive breast cancer maintenance
This trial tests a combination of two targeted drugs (pyrotinib and trastuzumab) as maintenance therapy to keep HER2-positive breast cancer that has spread under control. It is for women who have already received some first-line treatment and are stable enough to continue therapy.
Fuzhou, FujianAges 18–70 - NCT06298084RecruitingPhase 1/Phase 2
HER3-DXd for Advanced Breast Cancer After T-DXd
This study tests a new drug called HER3-DXd (alone or combined with other medicines) for people with advanced breast cancer that has already been treated with T-DXd (Enhertu) and then got worse. The goal is to see if the new drug can shrink tumors safely.
VillejuifAges 18 years+ - NCT05959291Recruiting
Stopping long-term anti-HER2 therapy in stable metastatic breast cancer
This study asks whether some people with HER2-positive metastatic breast cancer who have been stable for a long time can safely stop their ongoing (maintenance) anti-HER2 treatment. It also uses blood testing and close imaging follow-up to watch for early signs that treatment needs to restart.

Common questions
- Are there clinical trials for her2 positive?
- Yes. Clin2 currently lists 346 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.
