Primary outcomePrimary: Percentage of Participants With Progression Free Survival (PFS) at Week 24 — 69.4; 73.5 Percentage of participants
Summary
The primary objective is to evaluate whether Zoladex 10.8 mg (12-weekly) is non-inferior to Zoladex 3.6 mg (4-weekly) in pre-menopausal women with oestrogen receptor positive advanced breast cancer by assessment of progression-free survival at 24 weeks.
Secondary Objectives are to compare the safety and tolerability profile of ZOLADEX 10.8 mg and ZOLADEX 3.6 mg by assessment of adverse events (AEs)and to assess goserelin PK in Japanese and Caucasian participants who have received ZOLADEX 10.8 mg by assessment of goserelin plasma concentration time profiles
Recruitment into the study has been permanently stopped as of 24 December 2007 due to slow recruitment. 98 (vs the planned 260) patients were randomised into the study and will be followed as per protocol for 2 years
