*Intent-to-treat population.

Patients received the same number of injections

  • FASLODEX 500-mg arm received 2 x 250-mg injections on days 1, 15, and 29 and once monthly thereafter
  • FASLODEX 250-mg arm received 1 x 250-mg injection plus one placebo injection on days 1, 15 (2 placebo injections only), and 29 and once monthly thereafter

These numbers do not add up to 100%, since some patients had multiple sites involved.

Progression/Recurrence History at Randomization3

  • Most patients had recurrence during or within 12 months of completing adjuvant hormonal therapy (52.6%) or had progressed on their first endocrine treatment for de novo advanced disease (34.6%)

Preplanned for study of the following subgroups2,4

  • Receptor status
  • Visceral involvement
  • Response to last hormonal therapy before FASLODEX
  • Measurable disease
  • Age
