Study of PET imaging and blood tests for ER+ HER2- metastatic breast cancer
This trial tests a new imaging technique (18F-FES PET/CT) along with blood markers to guide treatment for metastatic breast cancer that is ER-positive and HER2-negative. It's for people whose cancer progressed on first-line hormone therapy and who are starting a second line of hormone therapy.
BayonneAges 18 years+ - NCT06259929RecruitingPhase 2
Neoadjuvant abemaciclib and giredestrant for early breast cancer
This trial tests a combination of two oral medications (abemaciclib and giredestrant) given before surgery to women with a common type of early breast cancer (hormone receptor-positive, HER2-negative). The goal is to see if this treatment can shrink the tumor before surgery.

Short-term hormone therapy before breast cancer surgery
This trial is testing how well a short course of hormone-blocking pills (endocrine therapy) works before surgery in women with early-stage hormone receptor-positive HER2-negative breast cancer. The goal is to understand what makes some cancers resistant to these treatments.
Milwaukee, WisconsinAges 18 years+ - NCT06375798Recruiting
Breast conservation with radiation during surgery for early breast cancer
This trial is for women aged 55 or older with very early-stage breast cancer (stage 0 or 1) who want to save their breast. It tests giving a single dose of radiation during the lumpectomy instead of weeks of daily radiation afterward.
Shijiazhuang, HebeiAges 55 years+ - NCT06462092RecruitingPhase 1/Phase 2
Sacituzumab Govitecan and Spinal Chemo for Breast Cancer Spread to Spinal Fluid
This trial tests a combination of a targeted antibody-drug (sacituzumab govitecan) and chemotherapy given into the spinal fluid.

GliwiceAges 18 years+ - NCT06691035RecruitingPhase 1
Targeting ESR1 mutation in hormone-positive breast cancer
This trial tests a new treatment for metastatic breast cancer that is hormone receptor-positive and HER2-negative, and has a specific genetic change called an ESR1 mutation. The goal is to see if targeting this mutation can help control the cancer.
Tampa, FloridaAges 18 years+ - NCT06757634RecruitingPhase 3
A study of gedatolisib for first-line advanced breast cancer
This trial tests a new targeted therapy called gedatolisib for people with HR-positive, HER2-negative advanced breast cancer who have not yet received treatment for metastatic disease. It aims to see if adding this drug to standard hormone therapy can help control the cancer longer.
Duarte, CaliforniaAges 18 years+ - NCT06769425RecruitingPhase 1

PF-07248144 with fulvestrant for HR+ HER2- advanced breast cancer
This trial tests a new study medicine (PF-07248144) combined with fulvestrant in people with a certain type of advanced breast cancer (HR-positive, HER2-negative) that has worsened after previous treatments. It may be an option if you've already tried a CDK4/6 inhibitor and endocrine therapy.
Chandler, ArizonaAges 18 years+ - NCT07164976RecruitingPhase 1/Phase 2
Ribociclib for advanced HR+ HER2- breast cancer
This trial tests a new combination of ribociclib and anastrozole as a first treatment for advanced hormone receptor-positive, HER2-negative breast cancer that has not been treated before. It may help if you have not received any prior therapy for metastatic disease.
NagoyaAges 18 years+ - NCT07190443RecruitingPhase 3
Abemaciclib after local recurrence in HR+ HER2- breast cancer
This trial tests whether adding a targeted drug (abemaciclib) to standard treatment helps prevent breast cancer from coming back again after a local recurrence in women with HR-positive, HER2-negative breast cancer.
Koto-ku, TokyoAges 18 years+ - NCT07207070RecruitingPhase 3
New drug combination for PIK3CA-mutated breast cancer
This trial tests a new combination of two drugs (JS105 plus dalpiciclib and fulvestrant) against a standard combination (dalpiciclib plus fulvestrant) for people whose breast cancer has a PIK3CA mutation. The goal is to see if adding JS105 helps control the cancer longer.
Beijing, Beijing MunicipalityAges 18–75 - NCT07218432Recruiting
TheraBionic device study for hormone-positive breast cancer
This trial tests a device called TheraBionic P1, which uses low-level radiofrequency energy, for women with early-stage hormone receptor-positive, HER2-negative breast cancer. It is given before surgery to see if it can help shrink the tumor.

Common questions
- Are there clinical trials for her2-negative?
- Yes. Clin2 currently lists 154 recruiting her2-negative 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 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 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.
