Discovery and Applications

Trastuzumab, also known as Herceptin, was developed in the late 20th century by researchers Genentech, a biotechnology company. The discovery of trastuzumab stemmed from the identification of the HER2/neu (Human Epidermal Growth Factor Receptor 2) gene, which is overexpressed in certain types of breast cancer. Trastuzumab was specifically designed as a monoclonal antibody to target and inhibit the HER2 protein.

Trastuzumab revolutionized the treatment of HER2-positive breast cancer, significantly improving survival rates and outcomes for patients. It is used in both early-stage and metastatic HER2-positive breast cancer, often in combination with chemotherapy or other targeted therapies. Trastuzumab has also shown efficacy in HER2-positive gastric cancer, expanding its therapeutic applications beyond breast cancer.
