This study is ongoing, but not recruiting participants.
Sponsor:
Information provided by (Responsible Party):
AstraZeneca
ClinicalTrials.gov Identifier:
NCT01073865
First received: February 22, 2010
Last updated: May 25, 2017
Last verified: May 2017
  Purpose
The purpose of this study is to examine the efficacy and safety as well as the characteristics of the female hormone and study medications after administration in pre-menopausal women with advanced or recurrent breast cancer who were randomised in a 1:1 ratio to either of the two treatment groups; the ZD9393 3.6 mg depot group or ZD9393 10.8 mg depot group, both given in combination with tamoxifen tablets.

Condition Intervention Phase
Breast Cancer Drug: ZD9393 (Zoladex) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: An Open Label, Randomised, Parallel Group, Multicentre Study to Compare ZOLADEX™ 10.8 mg Given Every 12 Weeks With ZOLADEX 3.6 mg Given Every 4 Weeks in Pre-menopausal Women With Oestrogen Receptor Positive Advanced Breast Cancer.

Primary Outcome Measures:
  • Number of Patients With Progression-free Survival (PFS) at 24 Weeks [ Time Frame: 24 weeks after the first dosing ]
    A patient is judged as progression-free survive at Week 24 if their PFS time is at least 24 weeks with no progression event prior to Week 24 (ie, overall visit response is complete response (CR), partial response (PR) or stable disease (SD) at a tumour assessment at least 24 weeks after randomization). Overall visit response is assessed according to the RECIST version 1.1. %PFS is the proportion of patients with PFS.


Secondary Outcome Measures:
  • Number of Responders at 24 Weeks [ Time Frame: 24 weeks after the first dosing ]
    Responders are defined as those patients with a best objective tumour response of CR or PR during the first 24 weeks of therapy. Tumour response is assessed according to the RECIST version 1.1. ORR is defined as the proportion of patients who are responders.

  • Oestradiol (E2) Serum Concentrations at 24 Weeks [ Time Frame: 24 weeks after the first dosing ]
    E2 serum concentrations (pg/mL) at 24 weeks


Enrollment: 222
