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).

1.  Primary:   Objective Response Rate (ORR)   [ Time Frame: baseline and every 12 weeks (+/- 2weeks) from randomization data up to data cut-off (19th march 2008) ]

2.  Secondary:   Time to Progression (TTP)   [ Time Frame: every 12 weeks from randomization (+/- 2 weeks) until data cut-off (19th march 2008) ]

3.  Secondary:   Clinical Benefit Rate (CBR)   [ Time Frame: every 12 weeks(+/- 2 weeks) from randomization to data up to data cut-off, 19th March 2008. ]

4.  Secondary:   Pharmacokinetic Parameter: Mean Population Clearance, a Measure of the Efficiency With Which Fulvestrant is Eliminated From the Body   [ Time Frame: Baseline to 12 weeks ]

5.  Secondary:   Pharmacokinetic Parameter: Mean Volume of Distribution at Steady State, a Measure of the Apparent Volume in the Body Into Which Fulvestrant Distributes   [ Time Frame: Baseline to 12 weeks ]

6.  Secondary:   Duration of Response (DoR)   [ Time Frame: RECIST tumour assessments carried out every 12 weeks from randomisation (+/- 2 weeks) until data cut-off on19th March 2008. ]
