NCT00044291

Brief Summary

The purpose of this study is to determine whether the first line combination hormonal therapy of an experimental drug, atamestane, plus an FDA-approved drug, toremifene (Fareston®), is more effective than another approved drug, letrozole (Femara®), in delaying the growth of breast cancer in postmenopausal patients with locally advanced or metastatic breast cancer, and whether the side effects of the combination are different from the side effects of letrozole.

  • Locally recurrent, locally advanced, locally metastatic disease not amenable to radiation therapy or surgery and/or distant metastatic disease
  • At least one tumor localization measurable in 2 dimensions (one diameter at least 2 cm for soft tissue/visceral disease assessed by CT/MRI scan or conventional X-ray technique, one diameter at least 1 cm for bone lesions assessed by conventional X-ray techniques)
  • Estrogen receptor and/or progesterone receptor positive (by laboratory/institutional standard) at the time of initial diagnosis or determined during subsequent biopsy/surgery of metastases
