Tucson, ArizonaAges 18 years+ - NCT04965064RecruitingPhase 2
Neratinib plus capecitabine for HER2-negative breast cancer brain mets
This study tests whether neratinib plus capecitabine can slow or shrink breast cancer that has spread to the brain. It is for people whose cancer shows an “overactive HER2 signal” on a specific tumor test, even though their cancer is labeled HER2-negative.
Rochester, New YorkAges 18 years+ - NCT04332588RecruitingPhase 1
Testing PET/MRI monitoring for HER2-positive breast cancer before surgery
This early-phase study looks at how well PET/MRI scans can monitor treatment response in people with HER2-positive breast cancer before surgery. You may be asked to undergo specific scans during “neoadjuvant” therapy (treatment given before the main operation).
Birmingham, AlabamaAges 18 years+ - NCT05985655RecruitingPhase 1/Phase 2
Study of GTAEXS617 for advanced solid tumors
This trial tests a new drug called GTAEXS617 for adults with certain advanced solid tumors that have not responded to standard treatments. It aims to see if the drug is safe and effective.
Los Angeles, CaliforniaAges 18 years+ - NCT06462963Recruiting
Single vs multiple radiation doses for cancer spread
This trial compares a single, strong dose of radiation to multiple smaller doses for treating cancer that has spread to a few spots. It aims to see which approach causes fewer side effects.
AalstAges Any age - NCT07739485RecruitingPhase 1/Phase 2
Oral paclitaxel before surgery for triple-negative breast cancer
This trial tests an oral form of a common chemo drug, paclitaxel, given before surgery for triple-negative breast cancer. It aims to find the best dose and see how well it shrinks tumors.
Guiyang, GuizhouAges 18–70 - NCT07648914RecruitingPhase 3
BL-B01D1 versus chemotherapy for advanced hormone-receptor-positive breast cancer
This trial tests a new targeted drug called BL-B01D1 against standard chemotherapy in patients with advanced breast cancer that is hormone-receptor-positive (HR+) and HER2-negative, and has stopped responding to hormone treatments. The goal is to see if the new drug works better or has fewer side effects.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05582538RecruitingPhase 2
Ceralasertib plus immunotherapy for advanced triple-negative breast cancer
This Phase 2 trial tests whether a drug called ceralasertib can help the immune system work better, followed by durvalumab plus nab-paclitaxel. It is for people with advanced triple-negative breast cancer whose cancer returned after earlier treatment, including chemotherapy and immune therapy.
Novara, NovaraAges 18 years+ - NCT04997993RecruitingPhase 1
Leflunomide for PTEN-altered or HER2-negative metastatic cancers
This Phase 1 trial studies whether leflunomide can slow or control advanced (metastatic) cancers in people whose tumors have specific PTEN changes or who have HER2-negative breast cancer. It’s primarily a safety-and-dosing study, but it may offer benefit if your cancer matches the tumor marker requirements.

Fullerton, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.

Common questions
- Are there clinical trials for primary breast cancer?
- Yes. Clin2 currently lists 711 recruiting primary 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 primary 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 primary 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.
