BeijingAges 18–75 - NCT04923542RecruitingPhase 1/Phase 2
Targeted drug plus focused brain radiation for breast cancer
This study tests whether abemaciclib (a targeted pill) given with focused radiation to brain tumors can control hormone receptor–positive, HER2-negative breast cancer in the brain. It’s designed to see if the combination helps shrink or slow the growth of brain metastases while keeping side effects manageable.
Tampa, FloridaAges 18 years+ - NCT07503808RecruitingPhase 1
IDE034 for advanced solid tumors with B7-H3 or PTK7
This study tests a new drug called IDE034 for people with advanced solid tumors that have certain markers (B7-H3 and PTK7). The drug may help by targeting these markers on cancer cells, and the study checks if it is safe and effective.
Denver, ColoradoAges 18 years+ - NCT07100600RecruitingPhase 2
Targeted drug with or without radiation for HER2-positive breast cancer brain tumors
This trial tests whether adding radiation therapy to a targeted cancer drug (trastuzumab rezetecan) is better than the drug alone for women with HER2-positive breast cancer that has spread to the brain. If you have untreated brain tumors from this type of breast cancer, this study aims to find the best way to stop them from growing.
Zhengzhou, HenanAges 18 years+ - NCT06764940RecruitingPhase 2
Utidelone and capecitabine for HER2-negative breast cancer with brain metastases
This trial tests if the combination of Utidelone and capecitabine can shrink brain metastases in people with HER2-negative breast cancer. It is designed for those whose cancer has spread to the brain and who have not had many prior treatments.
Duarte, CaliforniaAges 18 years+ - NCT05861830RecruitingPhase 3
Dalpiciclib plus hormone therapy after CDK4/6 treatment
This trial tests dalpiciclib together with hormone (endocrine) therapy in people with HR-positive, HER2-negative advanced breast cancer whose cancer has already responded poorly to a prior CDK4/6 inhibitor. It aims to see if this combination can better control the cancer after that earlier treatment has failed.
Beijing, Beijing MunicipalityAges 18–80 - NCT04802759RecruitingPhase 1/Phase 2
Testing drug combinations for recurrent or advanced ER-positive breast cancer
This early-phase trial tests several combinations of cancer medicines to slow or control ER-positive breast cancer that has returned or progressed. It also checks safety and whether tumor or blood biomarkers can help match the right treatment to the right person.
