Recruiting studies
- NCT05896865Recruiting
Personalized breast cancer radiation based on tumor biology
This trial studies whether adjusting radiation dose using how the tumor behaves can improve outcomes for people with locally advanced breast cancer that has spread to certain nearby lymph nodes. It may help deliver the right radiation intensity while avoiding unnecessary exposure.
SeoulAges 19 years+ - NCT06686459Recruiting
AI-assisted single-session radiotherapy after breast-conserving surgery
This trial tests a new approach where all radiation is given in one session using AI guidance. It is for women who had breast-conserving surgery with lymph node removal and need radiation afterward.
GuangzhouAges 18–70 - NCT06876714RecruitingPhase 3
Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response
This trial compares 6 months versus 12 months of HER2-targeted therapy for people with HER2+ breast cancer who had a complete response after chemo and trastuzumab. The goal is to see if a shorter treatment is just as effective.
Phoenix, ArizonaAges 18 years+ - NCT06869629Recruiting
Avoiding armpit lymph node removal in breast cancer
This trial tests whether it is safe to skip removing lymph nodes from the armpit when cancer has spread there but has been found by ultrasound. If you have breast cancer that has spread to armpit lymph nodes and are not getting chemotherapy before surgery, this study may be an option.
HelsinkiAges 18 years+ - NCT06860529RecruitingPhase 2
Immunotherapy plus chemo for early-stage HR+/HER2- breast cancer
This trial tests adding the immunotherapy drug serplulimab to standard chemotherapy for people with early-stage HR-positive, HER2-negative breast cancer. It aims to see if this combination can improve outcomes before surgery.
Zhengzhou, HenanAges 18 years+ - NCT06858449Recruiting
Exercise and protein during chemo for breast cancer
This study tests whether adding resistance training (like lifting weights) along with a protein shake after workouts can help women with breast cancer maintain muscle and bone health while they receive chemotherapy before surgery.
Pittsburgh, PennsylvaniaAges 20–89 - NCT06860815RecruitingPhase 2
Cemiplimab with liver radiation for breast cancer that spread to the liver
This trial tests a combination of a drug called cemiplimab (an immunotherapy that helps your immune system fight cancer) and a type of targeted radiation (Y-90 SIR-Spheres) given directly to liver tumors. It is for people with breast cancer that has spread to the liver and who have already had at least one type of chemotherapy.
Duarte, CaliforniaAges 18 years+ - NCT06867484Recruiting
Breast re-irradiation after second lumpectomy
This trial tests whether giving a second round of radiation to the breast after a lumpectomy for a recurrence is safe and effective. It is for people with a specific type of breast cancer (ER+HER2-) who meet strict criteria regarding prior radiation and tumor characteristics.
Boca Raton, FloridaAges 40 years+ - NCT05722795Recruiting
Imatinib to change triple-negative breast cancer to ER-positive
This trial studies whether imatinib (a pill medicine) can “convert” triple-negative breast cancer into an ER-positive type, which may change how the cancer behaves. If the conversion happens, it could open the door to more treatment options in the future.
GothenburgAges 18 years+ - NCT06830889RecruitingPhase 3
BL-M07D1 vs T-DM1 for HER2-positive breast cancer after neoadjuvant therapy
This trial tests whether a new drug called BL-M07D1 works better than an existing drug, T-DM1, for people with HER2-positive breast cancer who still have cancer cells after initial treatment (neoadjuvant therapy). The goal is to prevent the cancer from coming back.
Nanjing, JiangsuAges 18–75 - NCT06817954Recruiting
Breast reconstruction after mastectomy for breast cancer
This trial tests how safe and effective it is to remove the breast (mastectomy) and rebuild it right away during the same surgery. It is for women with early-stage breast cancer who want reconstruction instead of breast-sparing surgery.
Nanjing, JiangsuAges 18–75 - NCT06807502Recruiting
Blood test for breast cancer follow-up
This trial uses a simple blood test (ScreenCell device) to look for circulating tumor cells (CTCs) in women. It aims to see if CTCs help monitor breast cancer during follow-up, including for those with metastatic or newly diagnosed breast cancer, as well as healthy volunteers.
Neuilly-sur-SeineAges 18 years+ - NCT06806930RecruitingPhase 2
Predicting response to hormone therapy before breast cancer surgery
This trial tests whether we can predict how well hormone therapy works before surgery for early-stage breast cancer. It may help women with estrogen receptor-positive, HER2-negative or HER2-low breast cancer avoid or tailor treatments.
Washington D.C., District of ColumbiaAges 21 years+ - NCT06781996RecruitingPhase 3
Digital tool to help manage hormone therapy side effects
This trial tests a digital tool (a smartphone app) to help women and men with early breast cancer manage side effects from hormone therapy. The goal is to improve quality of life during treatment.
VillejuifAges 18 years+ - NCT06787339RecruitingPhase 2
Capecitabine for low-risk triple negative breast cancer
This trial tests whether a chemotherapy pill called capecitabine can help people with low-risk triple negative breast cancer after surgery. It is for patients with stage I disease who have certain features that suggest a lower chance of recurrence.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06763328RecruitingPhase 3
Metformin for insulin resistance after breast cancer chemo
This study tests if metformin, a common diabetes medicine, can help reduce insulin resistance in women who finished chemotherapy for early-stage breast cancer. It aims to improve long-term health and prevent future problems.
Duarte, CaliforniaAges 18 years+ - NCT06768268Enrolling by invitationPhase 1/Phase 2
Better lymph node imaging for breast cancer
This trial tests whether adding two common fluids (Mannitol and Voluven) before an ICG dye injection can help surgeons better see the lymph nodes that need to be removed during breast cancer surgery. It aims to make sentinel lymph node biopsies more accurate and safer.
Hsinchu CountyAges 20–70 - NCT06744465Recruiting
Light-based monitoring for breast cancer during chemo
This study uses a special light-based device to monitor breast cancer during chemotherapy before surgery. It is for women with HER2-positive or triple-negative breast cancer who are planning chemotherapy first.
Indianapolis, IndianaAges 18 years+ - NCT06738654Recruiting
Robotic breast-conserving surgery through the armpit for early-stage breast cancer
This trial tests a new robotic technique for removing early-stage breast cancer through the armpit, leaving no scar on the chest. It may be an option for women who want to keep their breast shape and avoid visible scarring.
Chongqing, Chongqing MunicipalityAges 18 years+ - NCT06716073Recruiting
Endoscopic vs standard breast-conserving surgery after chemo
This study compares two types of breast-conserving surgery for women who have already had chemotherapy before their operation. It aims to see if using a tiny camera (endoscope) leads to equally good long-term results as standard breast-conserving surgery.
Guangzhou, GuangdongAges 18–75 - NCT03740893RecruitingPhase 2
Test drug to block DNA damage in triple-negative breast cancer
This Phase 2 trial studies a treatment given around the time of breast surgery to help shrink or control residual (remaining) triple-negative breast cancer. It also checks biomarkers (lab signals) to understand who benefits, with some people receiving anti–PD-L1 immunotherapy and some not.
Bournemouth, DorsetAges 18 years+ - NCT06611813RecruitingPhase 2
Chemo plus immunotherapy for HR+/HER2- breast cancer
This trial tests whether adding an immunotherapy drug (toripalimab) to standard chemotherapy before surgery can help treat HR+/HER2- breast cancer. It is for women with early-stage breast cancer that has not spread to other parts of the body.
HangzhouAges 18–75 - NCT06671691Enrolling by invitationPhase 1
Single-dose radiation for low-risk breast cancer
This trial tests a single, high-precision dose of radiation to the tumor instead of standard surgery or multiple radiation sessions. It is for women with a small, low-risk breast cancer who cannot or choose not to have surgery.
Palma, Balearic IslandsAges Any age - NCT06681064Recruiting
Tracking breast cancer changes during pre-surgery treatment
This study looks at how breast cancer changes while you are receiving chemotherapy or targeted therapy before surgery. The goal is to better understand which treatments work best for different types of breast cancer.
