OsteoporosisPhase 2NCT00001720
Treatment of Childhood Osteoporosis With Alendronate (Fosamax)
A Phase 2 study testing Alendronate in people with Osteoporosis, run by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) at 1 site in United States.
Trial summary
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. Read more about this study

About this study
Official title: Alendronate Versus Placebo for Idiopathic Juvenile Osteoporosis
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.
Read the detailed description
Osteoporosis is a rare but serious condition in children. One of the least well understood forms of childhood osteoporosis is idiopathic juvenile osteoporosis. Affected children suffer from pain, decreased activity tolerance, and increased fractures, including vertebral compression fractures. Even mild childhood osteoporosis may have long-term consequences since individuals who achieve a lower peak bone mass during the first 2-3 decades of life may be at increased risk for osteoporosis as adults.
Alendronate (Fosamax (Trademark), Merck \& Co.), an aminobisphosphonate, is a potent inhibitor of bone resorption. It has been used to treat postmenopausal osteoporosis, idiopathic male osteoporosis, and glucocorticoid induced osteoporosis in adults. The goal of this protocol is to evaluate the effectiveness of Alendronate in children with glucocorticoid induced and idiopathic juvenile osteoporosis using a double-blind, randomized, placebo-controlled study design. We hypothesize that children treated with this drug will have an improvement in bone mineral density and decrease in osteoporotic fractures.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

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.

Who may be eligible to take part?
The sponsor lists 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00001720, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Sep 2016.
