Shanghai, Shanghai MunicipalityAges 18–75 - NCT05945732Recruiting
Testing T-DXd or chemo for HER2-low or HR-positive breast cancer
This study looks at treatment choices for adults with breast cancer that has spread and cannot be removed by surgery (unresectable metastatic disease). It focuses on people with HER2-low (and some HER2-ultralow) and/or hormone-receptor positive cancer, and compares how well treatments like T-DXd or standard chemotherapy work.
GrazAges 18 years+ - NCT07492394RecruitingPhase 2
Testing dalpiciclib with or without entinostat and letrozole for early breast cancer
This trial is testing a combination of three drugs (dalpiciclib, entinostat, and letrozole) for women with early-stage, hormone-receptor-positive, HER2-negative breast cancer. It aims to see if adding these medications before surgery can help shrink the tumor.
Shijiazhuang, HebeiAges 18–75 - NCT07581834RecruitingPhase 2
Dalpiciclib plus hormone therapy for early hormone-positive breast cancer
This study tests whether adding a new drug called dalpiciclib to standard hormone therapy improves outcomes for women with early-stage breast cancer that is hormone-receptor positive. The goal is to see if this combination is more effective and safe than hormone therapy alone.
Fuzhou, FujianAges 18 years+ - NCT07610720RecruitingPhase 2
Dalpiciclib With Anti-HER2 and Hormone Therapy for Advanced Breast Cancer
This trial tests a combination of three drugs—dalpiciclib (a new cell-cycle inhibitor), anti-HER2 therapy, and hormone therapy—for advanced breast cancer that is positive for both hormone receptors and HER2 protein. The goal is to help patients whose cancer has responded to initial treatment stay in remission longer.
Guangdong, GUANGZHOUAges 18–75 - NCT07612891RecruitingPhase 1/Phase 2
Testing INV-6452 for advanced breast cancer and solid tumors
This study tests a new drug called INV-6452 to see if it is safe and can help control advanced cancers that have grown despite prior treatment. The drug targets specific cancer cell weaknesses, particularly in hormone-sensitive breast cancers without HER2 mutations.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07617025Recruiting
Understanding Breast Cancer Subtypes in BRCA Carriers
This study examines how different molecular subtypes (patterns of genes and proteins) of breast cancer behave in people with BRCA1 or BRCA2 mutations. By studying tumor samples and medical records, researchers hope to better predict which treatments will work best and predict long-term outcomes for BRCA-positive breast cancer patients.
GenovaAges 18 years+ - NCT07657130RecruitingPhase 2
Timing of ADC drug for advanced breast cancer
This trial is testing the best time to give an antibody-drug conjugate (ADC) to people with advanced breast cancer that is HER2-negative. It aims to find out if giving this treatment after first chemotherapy fails can help slow the cancer's growth.
Shenyang, LiaoningAges 18–75 - NCT06650748Enrolling by invitationPhase 2
A study of hormone therapy with or without a targeted drug for breast cancer
This trial tests if adding a targeted drug (CDK4/6 inhibitor) to hormone therapy works better than hormone therapy alone for women with a certain type of breast cancer (HR+/HER2-). The study measures the activity of tumor cells (Ki-67) to help decide treatment.
BeijingAges 18–70 - NCT05645536Enrolling by invitationPhase 3
Safety follow-up for hormone-positive, HER2-negative breast cancer
This trial studies the safety of continuing endocrine therapy with ovarian suppression (for women) after you finish the earlier OVELIA study. It may help doctors confirm that the treatment remains safe for longer-term use.
Greenbrae, CaliforniaAges 18–51 - NCT04680715RecruitingPhase 2
Tested radiation before and after breast surgery in older women
This Phase 2 trial looks at a specific radiation timing and technique around the time of breast-conserving surgery. It may help reduce the chance the cancer comes back in selected older patients with certain early-stage, hormone-positive, HER2-negative breast cancers.
Clermont-FerrandAges 65 years+ - NCT05876065Recruiting
Maintenance chemotherapy to help control advanced breast cancer
This trial studies whether taking a combination of capecitabine and cyclophosphamide after your best prior treatment can help keep advanced breast cancer from growing. It may help people whose disease has already responded or is stable after “salvage” treatment.
ShanghaiAges 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.
