HLD-0117 study for metastatic breast cancer
This early-stage study tests a new drug called HLD-0117 in women whose metastatic breast cancer (cancer that has spread beyond the breast) has stopped responding to previous hormone and targeted therapies. The goal is to see if this drug can slow or shrink the cancer in patients who have limited options left.
New Haven, ConnecticutAges 18 years+ - NCT06656624RecruitingPhase 2
Ribociclib plus hormone therapy for advanced breast cancer
This trial tests a new approach: starting with a targeted pill (ribociclib) plus hormone therapy (an aromatase inhibitor), instead of immediate chemotherapy, for women with a specific type of breast cancer (ER low-positive, HER2-negative) that is growing quickly. If eligible, you would not have received any prior treatment for your advanced cancer.
Nanjing, JiangsuAges 18–99 - NCT03417115Recruiting
Breast cancer registry study of treatment and outcomes
This is a registry study that collects real-world information about breast cancer care at the start of treatment. It may help researchers better understand which treatments work best for different groups of people.
Many LocationsAges 18 years+ - NCT06738966RecruitingPhase 1
BL0175 for advanced HR-positive breast or gynecologic cancer
This trial tests a new drug called BL0175 for women with certain types of advanced breast, ovarian, or endometrial cancer that have stopped responding to hormone therapy. The goal is to see if the drug can help shrink tumors or slow down the cancer.
Changchun, JilinAges 18 years+ - NCT06762483Recruiting
Blood test for gene changes in advanced breast cancer
This trial uses a simple blood test to look for two specific gene changes (ESR-1 and gBRCA) in people with hormone receptor-positive, HER2-negative breast cancer that has spread. It aims to detect these mutations earlier and help guide future treatment decisions.
Milan, ItalyAges 18 years+ - NCT07242352RecruitingPhase 3
Comparing elacestrant to standard hormone therapy for high-risk early breast cancer
This trial tests a new hormone therapy drug called elacestrant against standard hormone treatments for people with a specific type of early breast cancer (ER+/HER2-) that has a high chance of coming back. The goal is to see if elacestrant works better at keeping the cancer from returning.
Mönchengladbach, North Rhine-WestphaliaAges 18 years+ - NCT06875128RecruitingPhase 2
Liver-directed chemo with standard chemo for breast cancer
This trial tests if giving a high dose of chemotherapy directly into the liver, followed by standard chemotherapy, is safe and works better than standard chemo alone for people with breast cancer that has spread mostly to the liver.
Tampa, FloridaAges 18 years+ - NCT04606446RecruitingPhase 2
Study drug for ER-positive, HER2-negative cancers after treatment
This Phase 2 study tests a new Pfizer medicine (PF-07248144) for certain advanced or metastatic breast, prostate, or lung cancers that have not responded to standard treatment or no standard options exist. You may qualify if you have a specific tumor type and a limited number of prior cancer treatments, and if your body functions (blood, liver, kidneys) and heart rhythm meet safety limits.
Scottsdale, ArizonaAges 18 years+ - NCT07616453RecruitingPhase 2
New Drug Plus Hormone Therapy for Hormone-Responsive Breast Cancer
This trial tests whether a new drug called culmerciclib, combined with hormone therapy, works better than hormone therapy alone for early-stage breast cancer that grows quickly and responds to estrogen. The goal is to shrink tumors before surgery and improve outcomes.
Hangzhou, ZhejiangAges 18–75 - NCT04985058Recruiting
Study of abemaciclib plus hormone therapy in breast cancer
This study uses real-world health records to learn about outcomes in people with hormone-receptor positive, HER2-negative breast cancer who were treated with abemaciclib along with hormone (endocrine) therapy. It may help doctors better understand how well this treatment works outside of clinical trials.
AthensAges 18 years+ - NCT06793553RecruitingPhase 2
Induction chemo then immunotherapy for PD-L1 positive triple negative breast cancer
This trial tests a two-step approach: first a short course of chemotherapy (paclitaxel and bevacizumab), followed by a combination of immunotherapy (atezolizumab) and a different chemotherapy (nab-paclitaxel). It's for people with advanced triple-negative breast cancer that has spread or cannot be removed, and whose tumors have a specific marker called PD-L1. The goal is to see if this sequence works better than standard treatments.
Koto-ku, 3-8-31, TokyoAges 18 years+ - NCT06926868RecruitingPhase 2/Phase 3
Izalontamab Brengitecan vs chemo for certain breast cancers
This trial tests a new drug called Izalontamab Brengitecan against standard chemotherapy for people with untreated advanced triple-negative or ER-low breast cancer who cannot take certain immunotherapy drugs.
Hot Springs, ArkansasAges 18 years+ - NCT04389632RecruitingPhase 1
Sigvotatug vedotin for advanced solid tumors that spread
This early-stage study tests a drug called sigvotatug vedotin in people with advanced solid cancers that cannot be removed or have spread. It aims to see how well the treatment works and what side effects it causes.

Tested 212Pb imaging drug for certain advanced GRPR tumors
This early-phase study tests how safe and tolerable an experimental radiation drug is for adults with certain advanced or metastatic cancers that show a target called GRPR. Doctors will also use special scans to confirm the tumor has the target so the treatment can be delivered to the right place.

This trial tests whether giving nivolumab before surgery (neoadjuvant treatment) can improve outcomes for people with certain resectable breast cancers. It focuses on tumor types linked to immune activity (like triple-negative and specific lab markers).
AmsterdamAges 18 years+ - NCT05075512RecruitingPhase 2
Anlotinib with fulvestrant for advanced, HR-positive, HER2-negative breast cancer
This trial studies whether adding anlotinib (a targeted medicine) to fulvestrant (a hormone-blocking injection) can improve outcomes for people with advanced HR-positive, HER2-negative breast cancer. It focuses on safety and effectiveness when cancer has returned or progressed after hormone treatments.
Hangzhou, ZhejiangAges 18 years+ - NCT07242118Recruiting
Radiation therapy for older women with breast cancer
This trial tests a precise, high-dose radiation treatment (called SABR) for older women with early-stage breast cancer who choose not to have surgery. It aims to control the tumor with fewer side effects and may be an option if you have a small, ER+, HER2- tumor that hasn't spread to lymph nodes.

- Are there clinical trials for her2-negative breast cancer?
- Yes. Clin2 currently lists 263 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.
