  Purpose
The primary purpose of this study is to establish if a 10.8 mg dose of ZOLADEX given 3 monthly is non-inferior to a 3.6 mg dose of ZOLADEX given monthly in terms of oestradiol suppression in patients with oestrogen receptor positive early breast cancer.

Condition Intervention Phase
Breast Cancer Drug: Goserelin acetate Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Primary Outcome Measures:
  • Zoladex 10.8mg depot (every 12 weeks) is non-inferior to Zoladex 3.6mg depot (every 4 weeks) in terms of oestradiol (E2) suppression in patient population by assessment of area under the curve of E2 concentration during the first 24 weeks of treatment. [ Time Frame: every 12 weeks ]

Secondary Outcome Measures:
  • Zoladex 10.8mg has similar safety and tolerability profile to Zoladex 3.6mg. Examination of goserelin pharmacokinetics (PK) in Japanese patients after injection of Zoladex 10.8mg. Efficacy of Zoladex 10.8mg is similar to 3.6mg by assessment of DFS. [ Time Frame: every 12 weeks ]
