  Purpose

The purpose of this study is to compare the efficacy of Faslodex (fulvestrant) to Nolvadex (tamoxifen) as first-line treatment for 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.

Primary Outcome Measures:
  • Time to disease progression (TTP) [ Time Frame: At the time of data cut-off for this trial, the median overall duration of follow-up was 441 days, with a total of 434 (73.9%) randomised patients, including 47 patients from Japanese centres having progressed. ] [ Designated as safety issue: Yes ]
    It is considered that these results indicate that adequate data were available for obtaining clinically meaningful information for the primary efficacy endpoint of time to disease progression


Secondary Outcome Measures:
  • Objective response rate (ORR) [ Time Frame: At the time of data cut-off for this trial, the median overall duration of follow-up was 441 days, with a total of 434 (73.9%) randomised patients, including 47 patients from Japanese centres having progressed. ] [ Designated as safety issue: Yes ]
    It is considered that these results indicate that adequate data were available for obtaining clinically meaningful information for the primary efficacy endpoint of time to disease progression

  • Duration of response (DoR) [ Time Frame: At the time of data cut-off for this trial, the median overall duration of follow-up was 441 days, with a total of 434 (73.9%) randomised patients, including 47 patients from Japanese centres having progressed. ] [ Designated as safety issue: Yes ]
  • Time to treatment failure (TTF) [ Time Frame: At the time of data cut-off for this trial, the median overall duration of follow-up was 441 days, with a total of 434 (73.9%) randomised patients, including 47 patients from Japanese centres having progressed. ] [ Designated as safety issue: Yes ]
  • Overall survival (OS) [ Time Frame: At the time of data cut-off for this trial, the median overall duration of follow-up was 441 days, with a total of 434 (73.9%) randomised patients, including 47 patients from Japanese centres having progressed. ] [ Designated as safety issue: Yes ]
  • Quality of Life (QOL) and Tolerability. [ Time Frame: At the time of data cut-off for this trial, the median overall duration of follow-up was 441 days, with a total of 434 (73.9%) randomised patients, including 47 patients from Japanese centres having progressed. ] [ Designated as safety issue: Yes ]
