Randomized Phase 2 Trial of Anastrozole Combined With Novel Agent ZD6474 in the Neoadjuvant Treatment of Postmenopausal Patients With Hormone Receptor-Positive Breast Cancer

In this study we plan to study the combination of ZD6474, a dual inhibitor of EGFR and VEGFR-2 with anastrozole in the neoadjuvant setting for patients with Stage I-III breast cancer. The aim is to overcome mechanisms of resistance and simultaneously block multiple critical signaling pathways known to stimulate breast cancer.
