Immune therapy and radiation for advanced colorectal or breast cancer
This trial tests a combination of stereotactic body radiation therapy (SBRT) and an immune-boosting drug (M5A-IL2) for colorectal or breast cancer that has spread and is no longer responding to standard treatments. The goal is to activate your immune system to fight the cancer.
Duarte, CaliforniaAges 18 years+ - NCT03804944RecruitingPhase 2
Vaccine trial for hormone-positive breast cancer
This Phase 2 study tests an individualized vaccine made from your tumor information to help your immune system fight hormone-positive breast cancer. You may be able to participate if you meet specific hormone-receptor, health, and treatment-timing requirements.
Los Angeles, CaliforniaAges 18–90 - NCT03829553RecruitingPhase 3
Radiation to breast lymph nodes versus standard breast cancer care
This Phase 3 trial tests whether a shorter, more focused radiation treatment to the regional lymph nodes works as well as the current standard approach for certain breast cancers. It may help patients by potentially improving treatment efficiency while keeping cancer control effective.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05297617RecruitingPhase 2
Shorter hormone therapy for low-risk postmenopausal breast cancer
This Phase 2 trial studies whether women with very low-risk, hormone-receptor positive breast cancer can safely take hormone therapy for a shorter time. It may help reduce side effects if shorter treatment works as well as the longer standard plan.
LimogesAges 51 years+ - NCT05731258Recruiting
Watch how liposomal doxorubicin is used after breast cancer
This is an observational study that follows people receiving add-on (adjuvant) chemotherapy after primary breast cancer. It aims to understand treatment patterns and outcomes for patients healthy enough to receive liposomal doxorubicin and who have no major complications.
Hangzhou, ZhejiangAges 18–75 - NCT05744687RecruitingPhase 2/Phase 3
Letrozole plus SPH4336 versus letrozole alone for breast cancer
This study tests whether adding SPH4336 to letrozole works better than letrozole plus a placebo for treating hormone-receptor–positive, HER2-negative breast cancer in people starting first-line treatment. It may help slow cancer growth more effectively if the added drug is beneficial.
Fuzhou, FujianAges 18–75 - NCT05766410RecruitingPhase 2
Testing three CDK4/6 pills to change the immune response
This phase 2 trial compares ribociclib, palbociclib, and abemaciclib to see how each one affects your body’s immune response in estrogen- and/or progesterone-receptor–positive, HER2-negative early breast cancer. If you fit the stage and health requirements, joining could help doctors learn which treatment best “modulates” the immune system.
TaipeiAges 20 years+ - NCT05831397Recruiting
Study tests tiny blood “packages” during breast cancer chemotherapy
This trial studies small particles in the blood (called extracellular vesicles) in people receiving chemotherapy before surgery for breast cancer. It may help doctors learn more about what those particles can tell them during neoadjuvant treatment.
Pavia, LombardyAges 18–80 - NCT05860465RecruitingPhase 2/Phase 3
Tested blood cancer medicine with hormone therapy for breast cancer
This trial studies SPH4336 given together with standard hormone (endocrine) therapy for breast cancer that has spread or cannot be treated with surgery. It aims to see whether the combination is safer and more effective than hormone therapy alone.
Guangzhou, GuangdongAges 18–75 - NCT05891093RecruitingPhase 3
Fluzoparib plus hormone therapy after surgery for breast cancer
This Phase 3 trial tests whether fluzoparib added to standard hormone (endocrine) therapy after early breast cancer surgery can improve outcomes and safety. It may help patients whose tumors are ER-positive, HER2-negative, and a specific SNF3 subtype.
Beijing, Beijing MunicipalityAges 18–70 - NCT05914961Recruiting
Tracking inflammation response in triple-negative breast cancer
This trial studies how a blood inflammation marker (CRP) changes after starting immunotherapy plus chemotherapy in people with triple-negative breast cancer. Results may help doctors predict who benefits from treatment and when.
TübingenAges 18 years+ - NCT06171360Recruiting
Gut bacteria and CDK4/6 inhibitor treatment in breast cancer
This study looks at how gut bacteria affect response to a type of targeted therapy (CDK4/6 inhibitors) combined with hormone therapy in breast cancer that is hormone receptor-positive and HER2-negative. It may help find out why some people respond better to treatment and could lead to better personalized care.
