Prevention of Steroid-Induced Osteoporosis in Children

Stopped early · Phase 1/Phase 2

Conditions studied: Osteoporosis

In brief

The purpose of this study is to determine whether the drug pamidronate can safely and effectively improve bone mineral density in growing children who have bone disease caused by taking steroid medications. People who take steroid medications called glucocorticoids, like prednisone or dexamethasone, for long periods almost always have decreased bone density and are at increased risk of breaking a bone. Research has shown that pamidronate improves bone density in adults who take glucocorticoids. However, use of pamidronate is not approved in children because it has not been extensively tested in children. It is possible that children will have a different response or unique problems with the medication because their bones are still growing. We will assign all study participants to one of two groups. One group will receive pamidronate intravenously (through a vein) every 3 months in addition of daily oral calcium and vitamin D and the other group will receive calcium and vitamin D. The study is scheduled to run for 36 months, with visits to the study center once every 3 months.

You may qualify if…

• Chronic inflammatory disease or transplant recipient, currently on steroid therapy at supraphysiologic dose (greater than hydrocortisone equivalent of 15 mg/m2/day) for more than 6 months
• Bone age less then 14 years in females, 16 years in males, to correspond to < 90% of peak BMD

• Presence of at least one atraumatic fracture (defined as fracture that occurs during activities of daily living, without a fall), or a vertebral fracture, OR
• AP lumbar spine BMD (determined by DEXA) of more than 2 or more SD below the mean lumbar BMD for a healthy child of similar stature (height age). OR
• A low trauma fracture (suspicious fracture - defined as a fracture the occurs with a fall from standing height or below, and not during a high velocity activity) and AP spine BMD 1.5 or more SD below the mean for height age, OR
• Recent loss of BMD of greater then 3% over a 6 month or greater interval at any one of the following sites, lumbar spine, total hip or whole body (excluding head). OR
