Brief Summary
We have previously evaluated the safety and efficacy of Alendronate in 10 patients with juvenile osteoporosis during a 12-month clinical trial. We have documented that Alendronate improved BMD of the spine and hip without any major side effects. There were no additional fractures during therapy. The present study is designed to further evaluate the safety and efficacy of Alendronate in 20 children with juvenile osteoporosis using a double-blind, randomized, placebo-controlled, cross-over protocol.

Outcome Measures
Primary Outcomes (2)
Number of Participants With Improvement in Bone Mineral Density (BMD) of Spine After Therapy
Participants were screened for BMD of lumbar spine using DXA scan at visit 12 months after alendronate or placebo treatment.

Study Arms (2)
1 Alendronate, Calcium, Vitamin D
EXPERIMENTALCrossover study. Year-1, 10 participants will take study medication, calcium and vitamin D supplements and other 10 participants will take placebo, calcium and vitamin D supplements. Year-2, they will crossover to the second arm of the study. Those who took study medication and supplements in year-1, will take placebo and supplements in the year-2, and those 10 participants who took placebo and supplements in the year-1, will take study medications and supplements in the year-2.
2 Placebo, Calcium and Vitamin D
PLACEBO COMPARATORYear-1, 10 participants will take Alendronate (study medication)and calcium and vitamin D supplement). Another 10 participants will take placebo, calcium and vitamin D. In year-2 they will crossover. Those who took alendronate in the first year, will take Placebo, calcium and vitamin D for 12 months and those who took Placebo in the first year, will take Alendronate, calcium and vitamin D in the second year (12 months).
Interventions
Group-1/Year-1:Alendronate, pill, 35mg or 70mg, weekly; calcium, pill, 500mg or 1000mg daily; vitamin D, liquid, 800IU, daily, depending upon the body weight, for 12 months. Group-1/Year-2:Placebo, pill, 35mg or 70mg, weekly; calcium, pill, 500mg or 1000mg daily; vitamin D, liquid, 800IU, daily, depending upon the body weight for 12 months. Group-2/Year-1:Placebo, pill, 35mg or 70mg, weekly; calcium, pill, 500mg or 1000mg daily; vitamin D, liquid, 800IU, daily, depending upon the body weight for 12 months. Group-2/Year-2: Alendronate, pill, 35mg or 70mg, weekly; calcium, pill, 500mg or 1000mg daily; vitamin D, liquid, 800IU, daily, depending upon the body weight for 12 months.
