Official title
Phase II Trial of the Combination of Letrozole 2.5 mg Daily and Trastuzumab 2 mg/kg Weekly in ErbB2 Positive and Estrogen Receptor and/or Progesterone Receptor Positive Metastatic Breast Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
