Looking at a blood test to track heart health during HER2 breast cancer treatment
This trial is checking if a simple blood test (NT-proBNP) can help spot early signs of heart side effects from certain breast cancer treatments (chemotherapy plus HER2 blockers). If successful, it might help doctors adjust treatment sooner to protect your heart.
GothenburgAges 18 years+ - NCT06353997RecruitingPhase 2
New immunotherapy combination before surgery for triple-negative breast cancer
This trial tests a new combination of two immunotherapy drugs (INBRX-106 and pembrolizumab) given before surgery for people with early-stage triple-negative breast cancer. The goal is to see if this treatment can shrink the tumor and improve outcomes.
Los Angeles, CaliforniaAges 18 years+ - NCT06439771RecruitingPhase 2
Testing YL202 for advanced breast cancer
This trial tests a new drug called YL202 for people with advanced breast cancer. It is for those who have already tried certain targeted treatments (HER2 or TROP2 antibody-drug conjugates) and they stopped working. The goal is to see if YL202 can help shrink tumors or slow cancer growth.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07132034Recruiting

This trial tests whether acupuncture can help reduce stress in people who finished breast cancer treatment in the last 6 months. You must have a distress score of 5 or higher, and you can be using other treatments or therapies.
BaselAges 18 years+ - NCT06500208RecruitingPhase 2
Adebrelimab plus chemo before surgery for high-risk breast cancer
This trial tests a combination of an immunotherapy drug (adebrelimab) plus chemotherapy before surgery for people with high-risk, hormone receptor-positive, HER2-negative breast cancer. The goal is to see if this approach can shrink tumors more effectively than chemotherapy alone.

Mammogram decision help for women in rural areas
This trial tests a shared decision-making tool to help women aged 39-49 talk with their doctor about whether to get a mammogram. It aims to make the choice clearer for patients in rural settings.
Keene, New HampshireAges 39–49 - NCT06523894Recruiting
Radiation therapy for breast cancer patients over 70
This trial tests a precise type of radiation called SBRT for breast cancer in patients aged 70 or older who cannot have surgery or choose not to. The goal is to see if this treatment can effectively control the tumor without surgery.
GenevaAges 70 years+ - NCT07528716RecruitingPhase 3
AI-guided treatment for HER2-positive breast cancer
This trial tests whether an artificial intelligence model can help doctors choose the best targeted therapy before surgery for HER2-positive breast cancer (a type of breast cancer with a protein called HER2). The goal is to improve how well the treatment works and reduce side effects.
ShanghaiAges 18–75 - NCT06643585RecruitingPhase 3
Comparing T-DXd to standard therapy for molecular relapse in early breast cancer
This trial compares a new drug called Trastuzumab-Deruxtecan (T-DXd) to standard treatment for people with early breast cancer whose cancer has come back at a molecular level (detected by a blood test) but hasn't spread to other parts of the body. The goal is to see if T-DXd can prevent the cancer from returning.
UlmAges 18–75 - NCT06666439Recruiting
Tracking lobular breast cancer with a blood test
This study is testing a new blood test that looks for cancer DNA to track how lobular breast cancer responds to treatment. It is for people whose cancer has spread and who have not yet started treatment for the spread.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06700070RecruitingEarly Phase 1
Testing a microdose drug in solid tumors before surgery
This study tests a tiny amount of an experimental drug (PBA-0111) injected directly into tumors that will be surgically removed later. The goal is to see how the drug affects the tumor tissue, which may help guide future treatments for solid tumors like head and neck cancer, certain sarcomas, or triple-negative breast cancer.
Shreveport, LouisianaAges 18 years+ - NCT06709651Recruiting
Gut bacteria treatment for triple-negative breast cancer
This trial tests whether a treatment that targets your gut bacteria (microbiome) can help fight triple-negative breast cancer before surgery. It is for people with newly diagnosed, untreated triple-negative breast cancer that has not spread far.
Cork, MunsterAges 18 years+ - NCT06810804RecruitingPhase 2
Study of NBQ72S for breast cancer that has spread to the brain lining
This trial tests a new drug, NBQ72S, for people with breast cancer that has spread to the lining of the brain or spinal cord (leptomeningeal metastasis). It aims to see if the drug is safe and helpful for these patients.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06907810Recruiting
Study of fat molecules in long-term breast surgery pain
This trial looks at how certain natural fat molecules in your body might relate to long-term pain after breast cancer surgery. It could help doctors better understand and treat chronic pain in the future.

You may qualify if you have this specific type of breast cancer and have received certain prior treatments.
New Haven, ConnecticutAges 18 years+ - NCT07074106RecruitingPhase 2
Lower chemo with tumor-fighting cells for stage I-II breast cancer
This trial tests whether giving less chemotherapy is safe when patients have high levels of tumor-infiltrating lymphocytes (TILs) — a sign that the body's immune system is already fighting the cancer. It is for women with early-stage, triple-negative breast cancer.

Common questions
- Are there clinical trials for primary breast cancer?
- Yes. Clin2 currently lists 715 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.
