Summary

Protocol 777-CLP-32 is the treatment and survival continuation protocol of Biomed 777-CLP-29, and will continue to compare combined hormonal therapy using the experimental aromatase inhibitor (AI) atamestane combined with the FDA-approved anti-estrogen toremifene (Fareston®), to the single agent FDA-approved aromatase inhibitor letrozole (Femara®) for the treatment of advanced breast cancer. The purpose of this study is to determine whether maximal estrogen suppression achieved via the combination of atamestane, plus toremifene (Fareston®), is more effective than letrozole (Femara®) in delaying the growth of breast cancer.
