E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to demonstrate that the percentage change in BMD of the total hip as measured by DXA at Year 9 relative to Year 6 in patients treated with zoledronic acid for up to 9 years in the CZOL446H2301 core and both extension studies (Group Z9) is significantly greater than in patients treated with zoledronic acid for 6 years in the CZOL446H2301 core and CZOL446H2301E1 studies followed by up to 3 years of placebo in Study CZOL446H2301E2 (Group Z6P3). |
|
E.2.2 | Secondary objectives of the trial |
Secondary efficacy objectives are:evaluating the differences between treatment groups with respect to the percentage change in total hip and femoral neck BMD at Year 7,8,and 9 relative to Year 0 for the Z9 group relative to the Z6P3 group;percent change in the total hip BMD at Year 7 and 8 relative to Year 6;the percentage change in femoral neck BMD at Year 7, 8 and 9 relative to Year 6;relative changes in biochemical markers at Year 7,8 and 9 compared to Year 0 for the Z9 group relative to the Z6P3 group;the change in height at Year 9 relative to Year 6 for the Z9 group relative to the Z6P3 group;cumulative incidence of clinical fractures and vertebral fractures at Year 7, 8 and 9 starting from Year 6 for the Z9 group relative to the Z6P3 group. Secondary safety objectives are: evaluating the adverse event profile, cardiac questionnaire, changes in laboratory, renal and ECG parameters. |
