title: Overview of the trastuzumab (Herceptin) anti-HER2 monoclonal antibody clinical program in HER2-overexpressing metastatic breast cancer. Herceptin Multinational Investigator Study Group.
abstract: The recombinant humanized anti-HER2 monoclonal antibody trastuzumab (Herceptin; Genentech, San Francisco, CA) was evaluated in human clinical trials for treatment of women with metastatic breast cancer who have tumors that overexpress HER2. The trastuzumab clinical program consisted of a series of phase I, phase II, and phase III clinical trials. Clinical experience with this novel biologic has been obtained in more than 1,000 women with HER2-overexpressing metastatic breast cancer. Two pivotal trials were performed to evaluate trastuzumab efficacy and safety: (1) trastuzumab in combination with chemotherapy as first-line therapy and (2) trastuzumab as a single agent in second- and third-line chemotherapy. Preliminary results of the pivotal clinical trials that have been presented at national meetings are summarized below. The data suggest that trastuzumab will be an important new treatment option for women with HER2-overexpressing metastatic breast cancer.
