ctDNA-Guided Reduced Chemo in HR+/HER2- Breast Cancer
This study is testing whether using a ctDNA blood test can help doctors decide if patients with hormone receptor-positive, HER2-negative breast cancer can safely receive less intensive chemotherapy after surgery. The goal is to reduce side effects while still preventing the cancer from coming back.
Beijing, Beijing MunicipalityAges 18–75 - NCT06966050Recruiting
Blood test registry for inflammatory breast cancer

Study of D-0502 for ER+ HER2- advanced breast cancer
This trial tests an oral drug called D-0502 for people with a specific type of advanced breast cancer (ER-positive, HER2-negative). It is for those whose cancer has returned or worsened after hormone therapy, and it may be an option before trying more chemotherapy.
Beijing, Beijing MunicipalityAges 18–75 - NCT06954831RecruitingPhase 2
Short-course radiation for early-stage breast cancer
This trial tests a shorter, more intense radiation schedule for people with stage I-III breast cancer after lumpectomy. It aims to find if giving a higher daily dose over fewer sessions is safe and effective.
Arcadia, CaliforniaAges 40 years+ - NCT06958991Recruiting
Laser scanner test during breast cancer surgery
This trial tests a new laser scanner that helps doctors see if all cancer cells are removed during breast-conserving surgery, which might reduce the need for a second operation.
Villars-sûr-glâne, Canton of FribourgAges 18 years+ - NCT06960291Recruiting
EXCEL Exercise Program for Cancer Patients in Canada
This study tests a national exercise program called EXCEL for people with cancer. It helps you start or continue safe physical activity to manage side effects and improve your well-being.
Calgary, AlbertaAges 18 years+ - NCT06961955RecruitingPhase 2
Shorter versus longer whole breast radiation for early-stage breast cancer
This trial compares a 5-day course of whole breast radiation plus a boost to the standard 9-day course for people with early-stage breast cancer who have certain risk factors, such as high-grade tumors or younger age. The goal is to see if the shorter treatment is just as safe and effective.
Salt Lake City, UtahAges 18 years+ - NCT06949410RecruitingPhase 1
HER2 vaccine study for high-risk breast cancer
This trial tests a vaccine designed to help the immune system fight remaining HER2-positive breast cancer cells after standard treatment. It is for people who have completed at least six months of HER2-targeted therapy and still have a high risk of the cancer coming back.
Indianapolis, IndianaAges 18 years+ - NCT06946238Recruiting
Single-dose radiation after surgery for low-risk breast cancer
This trial tests giving a single, very targeted dose of radiation right after surgery for early-stage breast cancer. It is for women age 40+ with small, low-risk tumors (Luminal A or B) that have been fully removed and have not spread to lymph nodes.
MilanAges 40 years+ - NCT06943521RecruitingPhase 1/Phase 2
Study of MT-4561 for advanced solid tumors
This trial tests a new drug called MT-4561 in people with advanced solid tumors that have not responded to prior treatments. It aims to see if the drug can help shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - NCT06942234RecruitingPhase 1/Phase 2
Study of JSKN016 for advanced HER2-negative breast cancer
This trial tests a new combination drug (JSKN016) for people with HER2-negative breast cancer that has spread or cannot be removed. It is for those who have not yet had advanced-stage treatment (except hormone therapy) and may offer a new option.
ShanghaiAges 18–75 - NCT06938555Recruiting
Can extending nightly fasting improve sleep and thinking in breast cancer survivors?
This study tests whether eating all your meals within a shorter window each day (prolonged nightly fasting) can help improve sleep and thinking skills in breast cancer survivors who have memory or concentration problems.

Using genetic risk scores to improve breast cancer prevention
This study is testing a new way to use your genetic information (along with your family history) to better understand your personal risk for breast cancer. The goal is to see if giving this risk report to women with higher genetic risk can help them and their doctors make more informed decisions about screening and prevention.
