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.
Stanford is not currently accepting new patients for this trial. You may want to check clinicaltrials.gov to see if other locations are recruiting.
