Neratinib before surgery for HER2-mutated invasive lobular breast cancer
This Phase 2 trial tests neratinib given before surgery to treat stage I–III invasive lobular breast cancer that has a specific HER2 mutation and is hormone-receptor positive. It may help shrink the tumor and improve control of cancer before and after surgery.
Atlanta, GeorgiaAges 18 years+ - NCT07631052RecruitingPhase 2
Low-dose Capecitabine for High-risk Early Breast Cancer
This study tests whether a low-dose chemotherapy pill called capecitabine can help prevent breast cancer from coming back in patients whose cancer shows signs of remaining disease (called MRD) despite standard treatment. The trial focuses on hormone-receptor-positive, HER2-negative breast cancers.
Toronto, OntarioAges 18 years+ - NCT06993506Recruiting
SKB264 alone or combined for advanced HER2- breast cancer
This study is a real-world treatment trial for people with advanced HER2-negative breast cancer (either triple-negative or HR+/HER2-). It tests a drug called SKB264, given alone or with other therapies, and aims to see how well it works in everyday clinical practice.
Hefei, AnhuiAges 18 years+ - NCT07544056RecruitingPhase 2/Phase 3
BEBT-209 Plus Chemotherapy for Triple-Negative Breast Cancer
This study tests a new drug called BEBT-209 combined with chemotherapy (carboplatin and gemcitabine) in women with advanced triple-negative breast cancer that has spread or cannot be surgically removed. The goal is to see if this combination can slow or stop cancer growth better than standard treatments.
Guangzhou, GuangdongAges 18–75 - NCT06492616RecruitingPhase 3
Elacestrant vs standard hormone therapy for high-risk early breast cancer
This trial tests a new hormone therapy pill (elacestrant) against standard hormone therapy for people with a common type of early breast cancer (ER+, HER2-) that has a higher chance of returning. You may qualify if you've already been on hormone therapy for 2 to 5 years and want to see if a different pill works better.
Daphne, AlabamaAges 18 years+ - NCT06914440RecruitingPhase 2
Radiation and immunotherapy before surgery for HR+/HER2- breast cancer
This trial is testing a new treatment approach for patients with a certain type of breast cancer (HR+/HER2-). It combines radiation therapy with chemotherapy and an immunotherapy drug before the patient's main surgery, to see if it can shrink or eliminate the tumor more effectively.
Xi'an, Shannxi ProvinceAges 18–75 - NCT06525766RecruitingPhase 2
Adaptive capecitabine therapy for metastatic ER+ HER2− breast cancer
This trial tests whether adjusting the dose of the oral chemotherapy capecitabine over time can control metastatic breast cancer that is estrogen-receptor positive (ER+) and HER2−. It is designed for patients who are starting capecitabine or have just started it, and the study will monitor blood changes and tumor response closely.

Common questions
- Are there clinical trials for her2-negative breast cancer?
- Yes. Clin2 currently lists 265 recruiting her2-negative 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-negative 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-negative 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.
