The Evaluation of the Efficacy and Tolerability of FASLODEX (Fulvestrant) and AROMASIN (Exemestane) in Hormone Receptor Positive Postmenopausal Women With Advanced Breast Cancer (EFECT)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this study is to compare the efficacy of Faslodex (fulvestrant) to Aromasin (exemestane) in hormone receptor positive postmenopausal women with advanced breast cancer. Patients will be treated until disease progression or until the investigator has determined that treatment is not in the best interest of the patient, whichever occurs first.
