Recruiting studies
- NCT06358625Recruiting
Study of brain recurrence risk in HER2-positive breast cancer
This study looks at women with HER2-positive breast cancer who will get chemotherapy before surgery. The goal is to find out what factors might increase the chance of the cancer spreading to the brain later on.

Aromatase inhibitors and diabetes risk in breast cancer
This study looks at how aromatase inhibitors, a type of hormone therapy for breast cancer, affect blood sugar and diabetes risk. It compares women taking these drugs to those on tamoxifen or healthy women, to see if there are changes in glucose control.
Rochester, MinnesotaAges Any age - NCT06551116Recruiting
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.

Trastuzumab deruxtecan vs standard chemotherapy before breast surgery
This Phase 2 study compares trastuzumab deruxtecan to standard chemotherapy given before surgery for HER2-positive breast cancer. It aims to see which treatment works better to shrink the tumor and spread before the operation.
MalmöAges 18 years+ - NCT06533826RecruitingPhase 2
Testing two antibody drugs for HER2-low breast cancer
This trial tests two antibody-drug conjugates (Enhertu and Datroway) for breast cancer that is HER2-low or HER2-0. It aims to find the best treatment sequence for people whose cancer has stopped responding to prior therapy.
Birmingham, AlabamaAges 18 years+ - NCT06517212RecruitingPhase 2
Tirzepatide for weight loss in MRD-positive early breast cancer
This study tests whether the weight-loss drug tirzepatide (Mounjaro) can help prevent breast cancer from coming back in people who are overweight and have a sign of leftover cancer cells in their blood (called MRD-positive). You must have already finished at least one year of hormone therapy for early-stage breast cancer.
Dallas, TexasAges 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.
Milan, LombardyAges 18 years+ - NCT06518837RecruitingPhase 2
Tirzepatide for weight loss in early breast cancer
This study tests if tirzepatide (a weight loss drug) can help women and men with early-stage hormone receptor-positive breast cancer who are overweight or obese. The goal is to see if losing weight can improve outcomes after completing their initial breast cancer treatment.
Elizabeth, New JerseyAges 18 years+ - NCT06503783RecruitingPhase 1
Study of BL-M17D1 for advanced breast cancer and solid tumors
This trial tests a new drug, BL-M17D1, for people with advanced breast cancer (HER2 positive or negative) or other solid tumors that have spread. It aims to see if the drug is safe and effective.
Harbin, HeilongjiangAges 18–75 - NCT06481956Enrolling by invitationPhase 2
T-DM1 plus a CDK4/6 inhibitor (ribociclib) for HER2-positive breast cancer
This clinical trial tests a combination of two targeted therapies for people with HER2-positive breast cancer that has spread or come back. The goal is to see if adding ribociclib to T-DM1 is safe and effective after other treatments have been used.
Hangzhou, ZhejiangAges 18–75 - NCT06486883RecruitingPhase 2
T-DXd vs CDK4/6i plus hormone therapy for advanced HR-positive, HER2-low breast cancer
This trial compares two treatments for advanced breast cancer that is HR-positive, HER2-low or ultralow, and a non-luminal subtype. It tests if a targeted antibody-drug conjugate (T-DXd) works better than the usual first-line therapy combining a CDK4/6 inhibitor with hormone therapy. This study is for people who have not had any treatment for advanced disease.

- Yes. Clin2 currently lists 244 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.
