Recruiting studies
- NCT06461650Recruiting
Nicotine Cessation Before Breast Reconstruction
This study tests whether a program to help women with breast cancer quit using nicotine before reconstructive surgery is feasible and helpful. If you use nicotine and are scheduled for reconstruction, you may be able to join.
Gainesville, FloridaAges 18–80 - NCT06468124Recruiting

Dalpiciclib for hormone receptor–positive advanced breast cancer
This trial studies whether dalpiciclib can slow down or control advanced hormone receptor–positive breast cancer and assess how safe it is. It’s for people whose cancer has come back in a limited way or spread and can’t be fully cured with surgery or radiation.
Shijiazhuang, HebeiAges 18 years+ - NCT04254263RecruitingPhase 3
Pyrotinib after breast cancer therapy for HER2-positive early disease
This trial studies whether adding pyrotinib after standard treatment helps prevent breast cancer from coming back in people with HER2-positive early-stage breast cancer. You may be eligible if you finished chemotherapy plus trastuzumab and still had signs of cancer in the tissue removed during surgery.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT04159142RecruitingPhase 2
Testing two chemo combos for advanced triple-negative breast cancer
This Phase 2 trial compares two chemotherapy combinations to see which works better for advanced triple-negative breast cancer. You would be asked to join one treatment arm based on study assignment and be followed for response and side effects.
Shijiazhuang, HebeiAges 18–70 - NCT06456554Recruiting
Dermal matrix study in breast reconstruction
This trial tests a special supportive material called acellular dermal matrix in women having two-stage breast reconstruction after mastectomy. The goal is to learn how well it works when the implant is placed directly under the skin, over the chest muscle.
Little Rock, ArkansasAges 22 years+ - NCT06444269RecruitingPhase 2
Precision radiation before surgery for early hormone-positive breast cancer
This trial tests a focused radiation treatment before surgery for early-stage breast cancer that is hormone receptor positive and HER2 negative. The goal is to give precise radiation only to the tumor, with the hope of reducing side effects and improving outcomes.
Dallas, TexasAges 18 years+ - NCT06452394RecruitingPhase 2
Testing doxycycline with chemo for breast cancer
This trial tests whether adding the antibiotic doxycycline to standard chemotherapy before surgery can better target breast cancer stem cells in people with ER-positive, HER2-negative breast cancer. The goal is to improve treatment response.
Sankt Gallen, Canton of St. GallenAges 18 years+ - NCT06447532Enrolling by invitation
Machine learning to track inflammation in breast cancer
This study uses a computer program to look at blood test results from women treated for breast cancer. The goal is to see if patterns in inflammation markers can help predict outcomes.
Buenos Aires, Buenos AiresAges 18–75 - NCT06455904Recruiting
Cycling exercise during chemo for breast cancer
This trial tests whether a special cycling exercise program during chemotherapy can help women with breast cancer. It is for patients who are about to start a common type of chemotherapy and want to add physical activity to their treatment plan.
ColmarAges 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+ - NCT06454864Recruiting
Exercise and Diet for Breast Cancer Survivors
This study tests whether a 6-month program combining weekly supervised exercise and dietary advice can improve health in breast cancer survivors who have completed initial treatments. It aims to help with weight, heart health, and overall well-being.
Toronto, OntarioAges Any age - NCT06443645Recruiting
Protecting the heart during breast cancer treatment
This trial tests whether a diabetes medicine (SGLT2 inhibitor) can prevent heart damage caused by a common chemotherapy drug (anthracycline) in people with early-stage breast cancer. If you are newly diagnosed and about to start chemotherapy or have surgery, this study may be for you.
StrasbourgAges 18 years+ - NCT06079983RecruitingPhase 3
JSKN003 vs. doctor's choice for HER2-low breast cancer
This trial compares a new experimental drug, JSKN003, to standard treatments chosen by your doctor for advanced breast cancer that tests as HER2-low (IHC 1+ or 2+ but not amplified). It's for people whose cancer has spread or can't be removed and who have already had one or two lines of chemotherapy.
Guangzhou, GuangdongAges 18 years+ - NCT06433609RecruitingPhase 2
ADC plus immunotherapy for advanced HER2-negative breast cancer
This trial tests a combination of an antibody-drug conjugate (ADC) and an immunotherapy drug (adebrelimab) for people with advanced HER2-negative breast cancer that has stopped responding to prior treatments. The goal is to see if this combination can help shrink or slow the cancer.
Beijing, Beijing MunicipalityAges 18–75 - NCT06435351RecruitingEarly Phase 1
Personalized vaccine for high-risk triple-negative breast cancer
This trial tests a personalized vaccine made from your own immune cells (dendritic cells) to help prevent your high-risk triple-negative breast cancer from coming back. It is for people who had significant tumor left after standard chemotherapy and surgery.
Tampa, FloridaAges 18 years+ - NCT06429995Enrolling by invitation
Standard follow-up program for breast cancer patients
This trial tests a standard follow-up program for people with breast cancer who are getting radiotherapy. It aims to see how well the program supports patients after treatment.
GroningenAges 18–99 - NCT06435429RecruitingPhase 3
Zanidatamab vs trastuzumab for HER2+ breast cancer

Blood test for tumor DNA after breast cancer chemo
This study tests a new blood test to see if it can find tiny bits of tumor DNA after chemotherapy. If you have a larger or higher-risk breast cancer and are getting chemotherapy before surgery, you may join. The test could help doctors know if your cancer is gone or if more treatment is needed.
Anchorage, AlaskaAges 18 years+ - NCT06414733RecruitingPhase 1
