Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Mean Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) Z-score at Month 12
Délai: Month 12
Lumbar Spine Bone Mineral Density (BMD) Z-score was determined by the central imaging vendor before first treatment and at Month 12. The methods to be used to measure Lumbar Spine BMD Z-score were described in the respective DXA Manuals provided by central imaging vendor. Positive changes from baseline indicated an improvement in condition.

Délai
Mean Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) Z-score at Month 6
Délai: Month 6
Lumbar Spine Bone Mineral Density (BMD) Z-score was determined by the central imaging vendor before first treatment and at Month 6. The methods to be used to measure Lumbar Spine BMD Z-score were described in the respective DXA Manuals provided by central imaging vendor.

Month 6, Month 12
Number of Participants With New Vertebral Fractures at Month 12
Délai: Month 12
New vertebral fractures were defined as fractures of Genant Grade 1 or higher that occurred at lumbar or thoracic spine from first dose infusion to the end of the study.
Month 12
Mean Change From Baseline in Vertebral Morphometry at Month 12
Délai: Month 12
Vertebral morphometry (or concave index) was calculated using the average ratio between mid-height and posterior height from L1 to L4 and performed by a central reader.
Month 12
Percentage of Patients With Reduction in Pain at Months 3, 6, 9 and 12
Délai: Month 3, Month 6, Month 9 and Month 12
Pain was evaluated at each visit (in office and telephone visit) at randomization, Months 3, 6, 9 and 12 using the Faces Pain Scale-Revised (FPS-R). Children were selecting the face that best fits their pain. The pain score ranged from 0 (No Pain) to 10 (Very Much Pain). The reduction in pain from baseline by visit was evaluated based on whether or not patients had a decrease in their FPS-R from baseline. If pain remained the same or worsened from baseline a patient was classified as '0' and if the pain scale decreased then the patient was classified as '1'.
Month 3, Month 6, Month 9 and Month 12
Mean Change From Baseline in 2nd Metacarpal Cortical Width at Month 12
Délai: Month 12
Left posteroanterior (PA) hand/wrist X-ray were taken at Visit 1 and at the Month 12 visit to assess bone age and the between-treatment differences for change in 2nd metacarpal cortical width at Month 12 relative to baseline. If a fracture of the left upper extremity precluded radiographic imaging, then the right hand was evaluated for this purpose. In this case, the right hand was be imaged at both Visit 1 and at Month 12. The information was used in the assessment of bone density.
Month 12
Urinary Concentration of Zoledronic Acid at Month 12
Délai: Month 12
Urine was collected overnight or for at least 4 waking hours from all patients able to provide specimens, to measure urinary concentration of zoledronic acid at Month 12. Only descriptive analysis done.
Month 12
Safety of Zoledronic Acid for the Treatment of Osteoporotic Children Treated With Glucocorticoids
Délai: Baseline through Month 12
Analysis of absolute and relative frequencies for treatment emergent Adverse Event (AE), Serious Adverse Event (SAE) and Deaths by primary System Organ Class (SOC) to demonstrate that zoledronic acid is safe for the treatment of osteoporotic children treated with glucocorticoids through the monitoring of relevant clinical and laboratory safety parameters. Only descriptive analysis done.
