Official title

Alendronate Versus Placebo for Idiopathic Juvenile Osteoporosis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Bones grow and stay strong through a continuous process of formation (building) and resorption (break down). When more bone is formed than resorbed, the density (level of calcium) in bone increases and the bones become stronger. However, if more bone is resorbed than formed the density of bone decreases and the bones become weak. This condition is called osteoporosis. Osteoporosis is a rare but serious condition in children. Childhood osteoporosis can occur without a known cause (idiopathic juvenile osteoporosis). Children with osteoporosis suffer from pain, inability to stay active, and increased amounts of broken bones, including fractures of the spine. Even mild childhood osteoporosis may have long-term consequences since individuals who achieve a less than normal bone composition (peak bone mass) during the first 20-30 years of life may be at an increased risk for osteoporosis as adults. Alendronate (Fosamax) is a drug that works by stopping bone resorption (break down). It has been used to treat post-menopausal osteoporosis, male osteoporosis and adults with osteoporosis due to long-term steroid therapy. The goal of this study is to determine the effectiveness of alendronate in children with idiopathic juvenile osteoporosis. Researchers believe that children treated with alendronate will improve bone strength and decrease the amount of fractures caused by osteoporosis.
