Taxane plus targeted therapy for early HER2-positive breast cancer
This trial tests a taxane chemotherapy combined with a targeted therapy for women with early-stage, HER2-positive breast cancer that has not spread to lymph nodes. It aims to provide a tailored treatment based on tumor size and risk factors.
Beijing, Beijing MunicipalityAges Any age - NCT06658951Recruiting
HER2-targeted CAR-T cell therapy for advanced solid tumors
This trial tests a new type of immunotherapy called CAR-T cells that are designed to attack cancer cells that have a high amount of a protein called HER2. It is for people with advanced solid tumors (like certain breast, stomach, or lung cancers) that have not responded to standard treatments.
Zhengzhou, HenanAges 18–70 - NCT06313086RecruitingPhase 3
New drug vs. T-DM1 for HER2-positive advanced breast cancer
This trial tests a new antibody-drug conjugate (DP303c) against an existing one, T-DM1, in people with HER2-positive advanced breast cancer who have already been treated with trastuzumab and a taxane. The goal is to see if the new drug works better or has fewer side effects.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06762977Recruiting
