T-DXd vs hormone therapy for HER2-low advanced breast cancer
This trial compares a targeted antibody-drug conjugate called T-DXd against standard hormone therapy for women with HR+, HER2-low advanced breast cancer that has progressed after first-line endocrine therapy plus a CDK4/6 inhibitor. It aims to see if T-DXd works better than continuing hormone therapy alone.

Study of a drug for breast cancer that has spread to a few spots
This trial tests a drug for people with HER2-positive breast cancer that has spread to only a few places in the body (up to 5 spots). It aims to see if the treatment works well before starting stronger therapies.
AmsterdamAges 18 years+ - 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.

Study of EIS-12656 for solid tumors with DNA repair defects
This trial tests a new drug, EIS-12656, alone or with other treatments, for solid tumors that have specific DNA repair problems called homologous recombination deficiency. It may be an option if your cancer has not responded to prior treatments.
Houston, TexasAges 18 years+ - NCT06102824RecruitingPhase 2

Common questions
- Are there clinical trials studying Trastuzumab?
- Yes. Clin2 currently lists 234 recruiting studies that include Trastuzumab, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Trastuzumab trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Trastuzumab an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Trastuzumab or a specific trial is right for you.
