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.
|Condition or disease||Intervention/treatment||Phase|
|Osteoporosis||Drug: Alendronate||Phase 2|
Patients receive oral alendronate sodium weekly for 1 year. Treatment continues in the absence of disease progression or unacceptable toxicity.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||10 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||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|
|Study Start Date :||September 2000|
|Primary Completion Date :||October 2003|
|Study Completion Date :||November 2008|
Experimental: 1 Alendronate for 12 months
Ten children will take alendronate 35mg or 70mg weekly depending upon the body weight for 12 months. Patients will also take calcium supplement daily.
Pill, 35mg or 70mg weekly, depending upon the body weight for 12 months.
Other Name: Fosamax
- Number of Participants With Increased Bone Mineral Density [ Time Frame: at 12 months ]Number of participants with increase in bone mineral density at Lumbar Spine and/or Hip at 12 months as compared to the bone mineral density at Lumbar Spine and/or Hip obtained before therapy (baseline values)
- 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. [ Time Frame: 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.
