Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations |
---|
Postmenopausal women with oestrogen receptor positive advanced breast cancer progressing or relapsing after previousendocrine therapy were randomized between 7th March 2006 and 4th September 2007. The trial was conducted in Japan only. One patient randomised to Fulvestrant 500mg was not dosed, so the Safety population has 46 patients for that arm. |
Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment |
---|
8 of the 151 enrolled patients were not randomized to treatment groups for the following reasons - 8 patients were incorrectly enrolled (ie did not comply with one or more inclusion / exclusion criteria). |
