Study of ESG401 for triple-negative breast cancer that has spread
This trial tests a new drug, ESG401, for people with triple-negative breast cancer that has come back or spread and cannot be removed by surgery. It compares ESG401 to standard chemotherapy options to see which works better.
BeijingAges 18 years+ - NCT06845319RecruitingPhase 2
Chemo-immunotherapy before surgery for triple-negative breast cancer
This trial tests a new combination of chemotherapy and immunotherapy that avoids a class of drugs called anthracyclines, which can be hard on the heart. The goal is to shrink tumors before surgery for people with triple-negative or low-hormone-receptor breast cancer.
Charleston, South CarolinaAges 18 years+ - NCT06998394RecruitingPhase 2
Cadonilimab Plus Chemoradiation for Oligometastatic Cervical Cancer
This trial tests a new immunotherapy drug (cadonilimab) combined with standard chemoradiation for cervical cancer that has spread to a few other places in the body. It aims to see if this combination can help control the cancer better.
Zhengzhou, HenanAges 18 years+ - NCT07097155Recruiting
