Letrozole, Herceptin in Her2neu +, Estrogen Receptor [ER] and/or Progesterone Receptor [PR] Positive, MBC

Summary

The purpose of the study is to investigate the effects (good and bad) that the combination of the drugs letrozole (also called Femara™) and trastuzumab (also called Herceptin®) has on breast cancer. The United States (US) Food and Drug Administration has approved both letrozole and Herceptin for the treatment of advanced breast cancer. Doctors hope that the combination will work better than either drug alone.
