San Francisco, CaliforniaAges 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+ - NCT05107674RecruitingPhase 1
Early drug study for advanced cancers that have limited options
This Phase 1 study tests NX-1607 in adults with advanced cancers that are hard to treat with standard care. It focuses on safety and early signs of how well the drug may work in specific cancer types.
Duarte, CaliforniaAges 18 years+ - NCT07064018RecruitingPhase 1/Phase 2
SPEDOX-6 for advanced solid tumors
This trial tests a new form of the chemotherapy drug doxorubicin, called SPEDOX-6, for people with certain advanced solid tumors that haven't responded to at least two prior treatments. The drug is designed to deliver doxorubicin directly to cancer cells while possibly reducing side effects.
Orange, CaliforniaAges 18 years+ - NCT07116161Recruiting
Exercise and counseling for fatigue in female breast cancer patients
This trial tests if combining exercise with cognitive behavioral therapy (counseling) can help reduce fatigue in women with breast cancer. You may be able to join if you have completed your initial treatments and still feel tired.
SingaporeAges 21 years+ - NCT07386444Recruiting
Breathing exercises for breast cancer patients on chemo
This trial tests whether special breathing exercises can help breast cancer patients feel better during chemotherapy. You would do simple, guided breathing workouts to strengthen your breathing muscles.
Columbus, OhioAges 18 years+ - NCT04601116RecruitingPhase 3
Atorvastatin for hormone-positive breast cancer to prevent recurrence
This Phase 3 study tests whether taking atorvastatin (a cholesterol-lowering medicine) can improve outcomes for women with estrogen-receptor–positive breast cancer. It may help by affecting cancer-related pathways and reducing risk of recurrence or progression.
AarhusAges 18 years+ - NCT07779135Recruiting
Aromatherapy for nerve pain from breast cancer treatment
This study tests whether using essential oils can help reduce pain, tingling, or numbness in hands and feet caused by paclitaxel chemotherapy for breast cancer. If regular pain medications aren't working well, this natural approach may offer additional relief.
ColmarAges 18 years+ - NCT07459062Recruiting
Spectral Tissue Recognition for Breast Cancer Surgery
This trial is testing a new way to identify cancer tissue during breast surgery. It may help surgeons remove cancer more completely during a lumpectomy.
Groningen, Provincie GroningenAges 18 years+ - NCT07407439Recruiting
Real-world study of CDK4/6 inhibitors in advanced breast cancer
This study looks at how well CDK4/6 inhibitors (a type of targeted therapy) work in real-world patients with HR+/HER2- advanced breast cancer. By collecting medical data from people treated at this hospital, doctors hope to learn more about the effectiveness and safety of these drugs in everyday practice.
TianjinAges 18 years+ - NCT06847555RecruitingPhase 1/Phase 2
Taurine cream to prevent skin burns from radiation in breast cancer
This trial tests if a taurine cream applied to the skin can prevent or reduce the painful skin reactions caused by radiation therapy for breast cancer. It may offer a simple way to protect your skin during treatment.
Jinan, ShandongAges 18 years+ - NCT07250204Recruiting
Testing nipple discharge to tell benign from malignant breast disease
This study uses a blood test and a sample of nipple discharge to see if it can help doctors tell the difference between non-cancerous and cancerous conditions in the breast ducts. It aims to find a better way to diagnose intraductal disease without needing surgery right away.
Wuhan, HubeiAges 18 years+ - NCT06505577Recruiting
Comparing Tumor Size Before and After Breast Cancer Surgery
This study compares the size of a breast tumor measured before surgery (using imaging tests like mammogram or ultrasound) with the actual size found after the tumor is removed. It helps understand how accurate preoperative measurements are for patients having breast cancer surgery.

Exercise study for early-stage triple-negative breast cancer patients
This study tests if aerobic exercise can help women and men with stage 2 or 3 triple-negative breast cancer who are getting chemotherapy and immunotherapy before surgery. It aims to see if exercise improves treatment outcomes and quality of life.
Houston, TexasAges 18 years+ - NCT07178886Recruiting
Breast Reconstruction and Radiation Therapy Study
This study looks at how breast reconstruction (rebuilding the breast shape) affects women who have had a mastectomy and need radiation therapy. It aims to see if reconstruction can be done safely and with good results when followed by radiation.
RotterdamAges 18 years+ - NCT06958627RecruitingPhase 2/Phase 3
Smart phone app vs standard care for breast cancer treatment
This trial tests whether a smartphone-based patient management program helps women with HER2-positive breast cancer take their medication (pyrotinib) more consistently compared to usual care. It may be a good fit if you are starting or continuing pyrotinib treatment.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05449691Recruiting
Compare natural tissue samples with synthetic mesh in breast reconstruction
This study looks at how “biological” materials compare with synthetic mesh during immediate, one-stage breast reconstruction after mastectomy. It may help doctors choose the best support material to improve reconstruction outcomes for women undergoing this surgery.

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.
