Recruiting studies
- NCT06185569Recruiting
French study on outcomes in HR+/HER2- early breast cancer patients with Oncotype DX
This study looks at how well treatments work for people with early-stage, hormone receptor-positive, HER2-negative breast cancer when the Oncotype DX test helps guide therapy. It aims to understand real-world outcomes in French patients.
BesançonAges 18 years+ - NCT06185972RecruitingPhase 2
MRI-guided ultrasound radiation for breast and chest cancer
This trial tests a new way to give radiation therapy using MRI imaging and ultrasound to make the radiation more targeted and potentially safer. If you have chest-wall or breast cancer and are already scheduled for radiation, this approach might offer a more precise treatment option.
Toronto, OntarioAges 18 years+ - NCT06220214RecruitingEarly Phase 1
Study of chemo before breast cancer surgery with special mammogram
This trial tests whether a special mammogram with contrast can help doctors see how well chemotherapy is working before breast cancer surgery. It is for women who plan to have at least 4 rounds of chemo before their operation.
Stony Brook, New YorkAges 18 years+ - NCT06224673RecruitingPhase 2
Testing ARX788 for HER2-low advanced breast cancer
This trial tests a new drug, ARX788, for people with HER2-low breast cancer that has spread or cannot be removed by surgery. The goal is to see if ARX788 helps shrink or control the cancer.
San Francisco, CaliforniaAges 18 years+ - NCT06225284RecruitingPhase 2
Chemotherapy with or without hormone drug for premenopausal TNBC
This trial tests whether adding a hormone-blocking drug (GnRH agonist) to standard chemotherapy before surgery helps premenopausal women with triple-negative breast cancer. It aims to improve treatment outcomes by targeting hormones that may fuel tumor growth.
TaipeiAges 18 years+ - NCT06236269RecruitingPhase 2
Sacituzumab Govitecan for HR+/HER2- advanced breast cancer
This trial tests a drug called Sacituzumab Govitecan for people with HR+/HER2- advanced or metastatic breast cancer that has stopped responding to a CDK4/6 inhibitor. It looks at whether the drug can slow down the cancer and requires you to have a tumor biopsy.
Badalona, BarcelonaAges 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.
Catania, CataniaAges 18 years+ - NCT06275126Recruiting

This study looks at how to make the best surgical choices for young women with breast cancer. It compares different surgery options to help guide treatment decisions.
New Haven, ConnecticutAges 18–44 - NCT06300125Recruiting
Freezing small low-risk breast tumors without surgery
This trial tests cryoablation (freezing the tumor with a needle) as a way to treat small, low-risk breast cancers without surgery. It is for women 50 or older whose cancers are hormone-receptor-positive and haven't spread to lymph nodes.
MilanAges 50 years+ - NCT06324240RecruitingPhase 1
Personalized vaccine plus immunotherapy for triple-negative breast cancer
This trial tests a personalized vaccine made from your tumor combined with immunotherapy drugs (pembrolizumab or ipilimumab) for triple-negative breast cancer. It aims to help your immune system recognize and attack cancer cells.
Atlanta, GeorgiaAges 18 years+ - NCT06834204Enrolling by invitation
Better care coordination for cancer survivors
This study tests a program to improve communication between your cancer team and your regular doctor. If you have heart or diabetes risks and you're being treated for breast, prostate, bladder, or endometrial cancer, this trial may help coordinate your care.
New Brunswick, New JerseyAges 18 years+ - NCT07570524Recruiting
Predicting Treatment Response in Early Triple-Negative Breast Cancer
This study helps doctors predict which patients will respond best to immunochemotherapy (a combination of immune-boosting and chemotherapy drugs) for early-stage triple-negative breast cancer. By understanding your tumor better before treatment, doctors may be able to personalize your care plan.
RennesAges 18 years+ - NCT06328465Recruiting
MRI for early detection of breast cancer spread
This trial is testing a new way to use MRI scans to find breast cancer that has spread to other parts of the body early. It is for people who have had aggressive breast cancer (HER2 positive or triple negative) and finished treatment with surgery, but still have a higher risk of the cancer coming back.
MilanAges 18–75 - NCT06341894RecruitingPhase 2
Dalpiciclib and hormone therapy for early breast cancer
This trial tests a new pill (dalpiciclib) combined with hormone therapy for women with early-stage, hormone receptor positive/HER2-negative breast cancer. The goal is to see if this combination can lower the chance of cancer coming back after surgery.
Nanjing, JiangsuAges 18–75 - 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+ - NCT06388122Recruiting
Blood test study for HR+ breast cancer treatment monitoring
This study looks at a blood test (DiviTum TKa) to see how well it measures treatment response in people with hormone receptor-positive (HR+) breast cancer that has spread. The test may help doctors know if a treatment is working.
Jacksonville, FloridaAges 18 years+ - NCT06439940Recruiting
Early breast cancer detection with blood test
This study tests a new blood test (liquid biopsy) that looks for tiny molecules called microRNAs to find early signs of breast cancer. It aims to detect cancer before symptoms appear, using a simple blood draw during your regular mammogram visit.
El Palomar, Morón, Buenos AiresAges 35 years+ - NCT06445738Recruiting
Can some women safely skip radiation after breast cancer surgery?
This trial is for women 50 and older with early-stage, hormone-positive or HER2-positive breast cancer. It tests whether it is safe to skip radiation therapy after a lumpectomy if an MRI before surgery shows the breast tissue looks a certain way.
San Francisco, CaliforniaAges 50 years+ - NCT06446882Recruiting
HER2DX test to guide treatment for early HER2+ breast cancer
This trial tests whether a new test (HER2DX) can help doctors choose the best treatment combination for HER2-positive breast cancer before surgery. It's for people whose cancer hasn't spread and who haven't started therapy yet.
GrazAges 18 years+ - NCT06479460Recruiting
Blood test monitoring during chemo before surgery for HER2-positive breast cancer
This trial tests whether a blood test (ctDNA) can help doctors monitor how well chemotherapy before surgery is working in women with HER2-positive breast cancer. It aims to see if changes in the blood can predict treatment success.
Nanjing, JiangsuAges 18–75 - NCT06587789Recruiting

Tirzepatide for weight loss in MRD-positive early breast cancer
This study tests whether the weight-loss drug tirzepatide (Mounjaro) can help prevent breast cancer from coming back in people who are overweight and have a sign of leftover cancer cells in their blood (called MRD-positive). You must have already finished at least one year of hormone therapy for early-stage breast cancer.

Common questions
- Are there clinical trials for early breast cancer?
- Yes. Clin2 currently lists 430 recruiting early 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 early 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 early 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.
