Recruiting studies
- NCT06234137Recruiting
Chemo plus targeted therapy for advanced HER2+ breast cancer
This trial tests a combination of chemotherapy (docetaxel and carboplatin) plus two targeted drugs (Inetetamab and Pyrotinib) for people with locally advanced HER2-positive breast cancer that has not spread to other parts of the body. The goal is to see if this powerful combo can shrink the tumor before surgery or other treatments.
Wenzhou, ZhejiangAges 18–75 - NCT07718425Recruiting
Endoscopic mastectomy surgery study
This study tests a new, less invasive surgery called endoscopic mastectomy for women who need breast removal. It aims to see how well the surgery works, how the breast looks and feels afterward, and whether nipple sensation is preserved.
Ponderano, BIAges 18–75 - NCT06274892Recruiting
Using an app to improve radiotherapy check-ins
This study tests whether using a mobile app to report symptoms during radiation treatment helps doctors better support patients. It is for people with breast or prostate cancer starting radiation therapy at Princess Margaret Cancer Centre.
Toronto, OntarioAges 18 years+ - NCT07686250RecruitingPhase 2
SAVI Scout for breast cancer surgery localization
This trial studies a new method (SAVI Scout) to help surgeons locate and remove breast tumors more precisely during surgery. It may reduce the need for multiple markers and improve outcomes.
Tampa, FloridaAges 18 years+ - NCT07587086Recruiting
PET/MR scan for breast cancer using fluorocholine
This study uses a special imaging scan (PET/MR) with a tracer called fluorocholine to see if it can help evaluate breast cancer before treatment or before surgery. It is for women who are newly diagnosed with breast cancer and will either have chemotherapy before surgery or go straight to surgery.
Taipei, TaiwanAges 25–75 - NCT06671262RecruitingPhase 2
Immunotherapy plus radiation before breast cancer surgery
This trial tests combining two treatments—an immunotherapy drug (Toripalimab) and radiation—before surgery for a certain type of breast cancer (HR+, HER2-negative) that has spread to lymph nodes. The goal is to see if this combination helps shrink the tumor more than standard therapy alone.
Hangzhou, ZhejiangAges 18–85 - NCT06266312Recruiting
Lifestyle program before breast cancer surgery
This study tests whether a program of healthy eating, exercise, and stress management before breast cancer surgery is practical and helpful for patients who will receive chemotherapy first. It aims to see if a lifestyle plan can improve your well-being during treatment.
Maastricht, LimburgAges 18 years+ - NCT07358377RecruitingPhase 1
Combination therapy for HR-positive, HER2-negative cancer
This trial tests a new drug, HRS-6209, combined with other treatments for people with hormone receptor-positive, HER2-negative cancer. The goal is to see if the combination is safe and works well.
Bowral, New South WalesAges 18 years+ - NCT07287098RecruitingPhase 2
Imlunestrant for premenopausal women with ER+/HER2- early breast cancer
This trial tests a new hormone-blocking pill (imlunestrant) in premenopausal women with early-stage ER+/HER2- breast cancer. Depending on whether you've had prior hormone therapy, the study will see if this treatment works better than standard options.
Birmingham, AlabamaAges 18 years+ - NCT07250386RecruitingPhase 1
CEA-targeted CAR-T therapy for advanced solid tumors
This trial tests a new CAR-T cell therapy that targets CEA, a protein found on certain cancer cells. It's for people with advanced solid tumors like lung or breast cancer who have not responded to other treatments.
Hangzhou, ZhejiangAges 18 years+ - NCT05835570Recruiting
PET scan using an integrin marker to find cancer
This trial uses a special PET/CT scan that targets a protein on some cancer cells to help detect and evaluate malignant tumors. It may help doctors better map tumors before any cancer treatment starts.
Wuhan, HubeiAges 18–85 - NCT07156253RecruitingPhase 1
Study of SYN818 with olaparib for advanced solid tumors
This trial is testing a new drug, SYN818, combined with olaparib for people with advanced solid tumors that have certain genetic changes (BRCA mutations or related DNA repair problems). It may be an option if you have ovarian or HER2-negative breast cancer and other treatments are no longer working.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07088263RecruitingPhase 3
Adaptive Chemotherapy for Advanced Breast Cancer
This trial tests a new approach to chemotherapy that adapts over time for people with advanced breast cancer that has not responded to first-line treatment. It is designed to personalize treatment based on how the cancer responds, potentially improving outcomes with fewer side effects.
Guangzhou, GuangdongAges 18–75 - NCT07070128Recruiting
AI screening tool for breast cancer genetic risk
This trial tests an AI tool that predicts genetic risk for breast cancer. It may help women identified as high-risk by their breast surgeon get quicker genetic counseling.
Golania, GoiásAges Any age - NCT07046689Recruiting
PET scans to check Trop2 ADC treatment in breast cancer
This trial uses a special PET scan to see if a type of drug called Trop2-ADC is working in people with advanced breast cancer. The scan may help doctors decide if the treatment is right for you.
Xiamen, FujianAges 18 years+ - NCT06956690RecruitingPhase 1/Phase 2
Testing HMBD-501 for HER3-positive advanced solid tumors
This trial tests a new drug, HMBD-501, for people with advanced solid tumors that have a specific protein called HER3. The goal is to see if the drug is safe and if it can help shrink or control the cancer.
La Jolla, CaliforniaAges 18 years+ - NCT06938724RecruitingPhase 2
Avoiding extra surgery in women with HER2+ or triple-negative breast cancer
This trial tests whether women with HER2-positive or triple-negative breast cancer who had a complete response to chemotherapy can safely skip radiation or additional surgery. If you had a complete tumor response after chemo and had breast-conserving surgery, you may be eligible.
MilanAges 18 years+ - NCT06672302Recruiting
Blood test to find high breast cancer risk
This study uses a blood test to help identify women who are at high risk for breast cancer. It is for Korean women aged 40 or older who have a suspicious breast finding and need a biopsy.
Honolulu, HawaiiAges 40 years+ - NCT06618287RecruitingPhase 1/Phase 2
Testing BMS-986507 for advanced lung and breast cancers
This study tests a new drug called BMS-986507, given in different combinations, for people with advanced solid tumors (lung cancer or breast cancer that has spread). It looks at safety, how the drug works in the body, and if it helps shrink tumors.
Birmingham, AlabamaAges 18 years+ - NCT05381038RecruitingPhase 1/Phase 2
Personalized azacitidine combinations for breast or stomach cancer
This Phase 1/2 trial tests different combinations that include azacitidine, chosen based on your tumor’s lab “response markers” and past drug-sensitivity screening. It aims to find safer dosing and see whether these personalized combinations can shrink solid tumors such as breast or stomach cancer.
SingaporeAges 21–99 - NCT05949983Recruiting
Exercise program for women with breast cancer
This study looks at how a tailored (adapted) physical activity program affects health outcomes and costs for women with breast cancer. It may help you stay active and feel better during or after treatment, while researchers track the program’s overall value.
ToulouseAges 18 years+ - NCT05876390Enrolling by invitation
Regional anesthesia to reduce long-term breast surgery pain
This trial studies whether a pain-control technique called regional anesthesia during certain breast surgeries can lower chronic (long-lasting) pain after surgery. It may help improve comfort and quality of life for people at risk of ongoing pain after their breast operation.
Milan, LombardyAges 18 years+ - NCT05704283RecruitingEarly Phase 1
3D ultrasound to check lymph nodes in breast cancer

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,417 recruiting 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 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 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.
