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+ - 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+ - 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+ - NCT06930521Recruiting
Monitoring heart health during HER2 therapy for breast cancer
This study tracks how well the heart handles HER2-targeted therapy (like Herceptin) during the first year of treatment for early-stage breast cancer. It helps keep you safe by checking heart function closely.
Toronto, OntarioAges 18–79 - NCT06922708Recruiting
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.
RomaAges 18–79 - NCT06914440RecruitingPhase 2
Radiation and immunotherapy before surgery for HR+/HER2- breast cancer
This trial is testing a new treatment approach for patients with a certain type of breast cancer (HR+/HER2-). It combines radiation therapy with chemotherapy and an immunotherapy drug before the patient's main surgery, to see if it can shrink or eliminate the tumor more effectively.
Xi'an, Shannxi ProvinceAges 18–75 - NCT06665178RecruitingPhase 2
Testing SG after T-DXd in ER+/HER2-low metastatic breast cancer
This trial tests whether a different chemotherapy drug, called sacituzumab govitecan (SG), can help people with ER+/HER2-low metastatic breast cancer who have already been treated with trastuzumab deruxtecan (T-DXd). It also looks at genetic markers in your tumor to predict who might benefit from SG.
Vancouver, British ColumbiaAges 18 years+ - NCT06902311RecruitingPhase 2
Shorter radiation after lumpectomy for early breast cancer
This trial tests a shorter, more intense course of daily radiation therapy (called ultra hypo-fractionation) given after lumpectomy for early-stage breast cancer. The goal is to reduce the number of treatment visits while keeping the same high level of effectiveness and safety.
Chapel Hill, North CarolinaAges 50 years+ - NCT06907095Recruiting
Early cancer detection study for high-risk individuals
This study tests if a simple blood or fluid test can find cancer early in people with a higher-than-average risk. If you have certain genetic mutations, a strong family history of cancer, or other high-risk conditions, you may be able to join.
VillejuifAges 18 years+ - NCT05796973RecruitingPhase 3
Exercise and atorvastatin for metastatic cancer outcomes
This trial tests whether a structured exercise program, along with the cholesterol medicine atorvastatin, can improve outcomes in people with metastatic prostate, breast, ovarian, or kidney cancer. It may help by reducing inflammation and supporting physical function during cancer treatment.
Tampere, Länsi-SuomiAges 18–99 - NCT06896474Recruiting
Breast cancer treatment choice help for women 70 and older
This study tests a decision aid to help women 70 and older with early stage breast cancer choose their treatment. It looks at whether the tool helps patients and their doctors make a confident treatment choice.
Los Angeles, CaliforniaAges 18 years+ - NCT06890871Enrolling by invitationPhase 1/Phase 2
Radiation with immunotherapy and anti-angiogenic therapy for advanced HER2-negative breast cancer
This trial tests a combination of radiation therapy, immunotherapy, and a drug that blocks blood vessel growth for advanced HER2-negative breast cancer that has spread. It is for patients whose cancer has worsened after at least two prior treatments.
