Phase II Study of Alendronate Sodium in Children With High-Turnover Idiopathic Juvenile Osteoporosis
A Non-Randomized, Open-Label, Prospective, Non-Controlled, 12-Month Clinical Trial to Determine the Effects of Alendronate 35 or 70 mg/Week Depending Upon Body Weight, in Children and Adolescent With IJO
OBJECTIVES:
I. Determine the effects of alendronate sodium on skeletal remodeling and bone mineral density of the hip and spine in children with high-turnover idiopathic juvenile osteoporosis.

Tidsramme |
|---|---|---|
|
Participants (1) With Fractures Before and After Therapy,(2)Analysed for Average Changes From High to Near Normal Mineral Apposition Rate (MAR) After Therapy,(3)Analysed for Average Insignificant Changes in Biochemical Markers After Therapy.
Tidsramme: Before and 12 months after treatment with alendronate
|
Participants (pts) with fractures bef.and aft.therapy; pts analysed for average changes in mineral apposition rate (MAR) (high (1.9um/day) to near normal (1.2 um/day)as revealed in bone biopsies.
MAR is the distance between the two tetracycline labels (um/day).
The data represent the average of 10-17 measurements of the disltance obtained by reading 2-7 individual slides of bone biopsy and pts analysed for average insignificant biochemical markers (serum bone specific alkaline phosphatase for bone formation and urinary N-telopeptide for resorption)to determine the effect of therapy.
