Treatment of HER2-Positive Metastatic Breast Cancer With Herceptin and Bevacizumab (Antibodies Against HER2 and VEGF)

Phase 1
Completed
Conditions
Breast Cancer
Registration Number
NCT00095706
Lead Sponsor
Translational Oncology Research International
Brief Summary

The purpose of this study is to evaluate the safety and effectiveness of combined treatment with trastuzumab (Herceptin) and bevacizumab (anti-VEGF antibody) in patients with HER2-positive metastatic breast cancer.

Detailed Description

Based on preclinical experiments conducted in our laboratories, we hypothesize that the aggressive behavior of HER2-overexpressing breast cancers is due in part to increased angiogenesis resulting from HER2-induced increases in vascular endothelial growth factor (VEGF) expression. In vivo experiments suggest that combined blockade of the HER2 receptor and VEGF results in superior anti-tumor efficacy compared with either treatment alone.

The current clinical trial, for which the phase I portion has been completed, will examine the efficacy and safety of trastuzumab (Herceptin) and bevacizumab (anti-VEGF antibody) in the treatment of HER2-overexpressing metastatic breast cancer.
