Immune therapy and radiation for advanced colorectal or breast cancer
This trial tests a combination of stereotactic body radiation therapy (SBRT) and an immune-boosting drug (M5A-IL2) for colorectal or breast cancer that has spread and is no longer responding to standard treatments. The goal is to activate your immune system to fight the cancer.
Duarte, CaliforniaAges 18 years+ - NCT05111561RecruitingPhase 1
Testing a two-drug combo for RAS-mutant or triple negative breast cancer
This study tests a combination of two new drugs, ZEN003694 and binimetinib, for people with advanced solid tumors that have certain gene changes (like RAS mutations) or triple negative breast cancer. The goal is to see if this combination can shrink tumors or slow their growth.
Boston, MassachusettsAges 18 years+ - NCT05307705RecruitingPhase 1
Testing LOXO-783 for PIK3CA-mutated cancers
This trial tests an experimental drug (LOXO-783) for people with advanced breast cancer or other solid tumors that have a specific change in the PIK3CA gene. The goal is to see if the drug can shrink or slow the growth of the cancer.
Scottsdale, ArizonaAges 18 years+ - NCT07401381RecruitingPhase 1
Injectable vs. oral letrozole in early breast cancer
This study compares a new injectable form of the drug letrozole with the standard oral pill. It aims to find out if the injection works as well as the pill for women who have already taken letrozole for their early breast cancer and have finished their initial treatment.
MurciaAges 18–80 - NCT07711847Recruiting

Mindfulness program for better sex after breast or gynecologic cancer
This study tests an online mindfulness program to help women with breast or gynecologic cancer improve their sexual health. The program is designed for survivors who have concerns about their sex life after treatment.
Corvallis, OregonAges 18 years+ - NCT06452485Recruiting
Re-irradiation with or without hyperthermia, or surgery only for recurrent breast cancer
This trial compares three treatment options for breast cancer that has come back in the chest or lymph nodes after previous radiation. It looks at adding hyperthermia (heating the tumor area) to re-irradiation, versus just re-irradiation or surgery alone, to see which offers better quality of life and survival with fewer side effects.
AmsterdamAges 18 years+ - NCT06555068RecruitingPhase 1/Phase 2
Study of HRS-6209 combinations for advanced breast cancer
This trial tests a new drug, HRS-6209, combined with different hormone treatments (fulvestrant, letrozole, HRS-8080, or HRS-1358) for people with advanced breast cancer that has spread or cannot be surgically removed and has worsened after previous treatments.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07264985Recruiting
Gut bacteria and diarrhea in breast cancer patients on pyrotinib
This study looks at how gut bacteria relate to diarrhea in breast cancer patients who are taking a drug called pyrotinib. By understanding this link, doctors hope to better manage side effects in the future.
Wuhan, HubeiAges 18–75 - NCT07630935Recruiting
Breast Cancer Risk Check for Night Shift Workers
This study helps women who work night shifts understand their personal breast cancer risk and get personalized advice to stay healthy. Researchers will review your health history and work schedule to create a customized care plan.
ParisAges 18 years+ - NCT03275311Recruiting
Care approach changes for metastatic breast cancer
This trial looks at how treatment care for metastatic breast cancer has evolved over time. You may be eligible if you are an adult receiving active cancer treatment in a comprehensive cancer center in France.
AngersAges 18 years+ - NCT05633654RecruitingPhase 3
Test drug combo versus standard care for triple-negative breast cancer
This trial tests a cancer antibody-drug combination plus pembrolizumab (immunotherapy) versus standard treatment. It’s for people with triple-negative breast cancer that still has invasive disease in the breast or lymph nodes after surgery and chemotherapy before surgery.
Birmingham, AlabamaAges 18 years+ - NCT05996107RecruitingPhase 1
Ribociclib with radiation for high-risk HR+ breast cancer
This trial tests whether adding the targeted therapy ribociclib (Kisqali) to radiation after surgery reduces the risk of breast cancer returning in patients with high-risk, hormone-positive breast cancer.
Ann Arbor, MichiganAges 18 years+ - NCT03265379Recruiting
Registry study for breast cancer invading the chest wall
This study follows people with breast cancer that has spread into the chest wall who are planning full-thickness chest wall surgery. It aims to improve quality of life by collecting real-world information during and after treatment.
Toronto, OntarioAges 18 years+ - 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+ - NCT03449238RecruitingPhase 1/Phase 2
Pembrolizumab with focused brain radiation for breast cancer brain spread
This trial studies whether pembrolizumab (an immune therapy medicine) plus stereotactic radiosurgery (focused radiation) can better control brain metastases from breast cancer. It may help shrink or slow growth of multiple brain spots with minimal treatment to surrounding tissue.
New York, New YorkAges 19–90 - NCT03448926Recruiting
DCIS test registry to guide radiation and drug decisions
This study collects information from people with breast ductal carcinoma in situ (DCIS) to see how a specific lab test (DCISionRT) may help predict who benefits from radiation and/or certain medications. Your results and clinical details are gathered during routine care, not necessarily to change treatment right away.
Scottsdale, ArizonaAges 30–85 - NCT03451383Recruiting
Study brain changes in older breast cancer patients
This study follows older women with newly diagnosed breast cancer to see who might develop thinking or memory problems over time. It may help researchers understand early brain risk and how treatment and other factors relate to cognitive decline.
Washington D.C., District of ColumbiaAges 60–105 - NCT03452774Recruiting
AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Birmingham, AlabamaAges Any age - NCT03463954Recruiting
Laser treatment trial for small breast tumors
This trial tests a focused laser treatment (Novilase®) to destroy small, cancerous breast tumors while aiming to work with standard care. It may help people who have an early, localized tumor that can be clearly seen on imaging so doctors can guide the laser safely.
Duarte, CaliforniaAges 18 years+ - NCT03572374Recruiting
Sharing breast cancer treatment plans with your workplace

Doxorubicin plus pembrolizumab for hormone-resistant breast cancer
This Phase 1b/2 trial tests a combination of pegylated liposomal doxorubicin and pembrolizumab for breast cancer that no longer responds to hormone treatment. It aims to see how well the combination works and how safely it can be given to patients with advanced disease.
JerusalemAges 18 years+ - NCT03667417Recruiting
Study of people with BRCA1/BRCA2 cancer gene changes
This study follows people who carry a harmful BRCA1 or BRCA2 gene mutation, whether or not they currently have breast or ovarian cancer. The goal is to better understand cancer risk over time and how being a carrier may affect screening and care.
MarseilleAges 18 years+ - NCT03671044RecruitingPhase 3
Testing a nano-form of docetaxel for triple-negative breast cancer
This Phase 3 study tests whether a special form of docetaxel (a chemotherapy drug) works better and is safe for people with triple-negative breast cancer that has spread or grown locally. You may be eligible if your cancer is triple-negative and you have measurable disease that can be tracked on scans, along with adequate organ and heart function.

- How do I know if I qualify for a breast 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 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.
