E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To prove superiority of zoledronic acid compared to alendronate by testing the hypothesis that the change of the level of NTx in serum within the first 12 months after start of therapy in postmenopausal women is higher. |
|
E.2.2 | Secondary objectives of the trial |
• To compare the level of NTx and P1NP • To compare the level of NTx within subgroups defined by baseline characteristics • To compare the effect within subgroups defined by T-score level at entry (-2 to -2.5 (exclusive), -2.5 to -3.0 (exclusive), -3.0 to -3.5 (exclusive), -3.5 to -4.0 (exclusive), -4.0 and lower)) • To compare the level of compliance and persistence • Descriptive analysis of changes in safety lab, AE and vital signs • To explore patient preferences for annual i.v. therapy compared to weekly oral therapy • To explore the change in quality of life between zoledronic acid and alendronate as measured by VAS and Quallefo-41 • To explore the number of clinical fractures • To explore the change in body height • To explore the number of days on osteoporosis related sick leave • Descriptive evaluation of onset as well as offset of both treatments at the beginning and at the end of observation period by values of NTx. |
