Encouraging Calcium Absorption and Bone Formation During Early Puberty
A Phase 1/2 study testing Nondigestible oligosaccharide (NDO) in people with Osteoporosis and Osteopenia, run by Baylor College of Medicine at 1 site in United States.
Trial summary
Increasing bone mass during puberty can ultimately decrease the risk of developing osteoporosis, which causes bones to weaken and break more easily later in life.

About this study
Official title: Optimization of Calcium Absorption and Bone Formation During Early Puberty
Increasing bone mass during puberty can ultimately decrease the risk of developing osteoporosis, which causes bones to weaken and break more easily later in life. The purpose of this study is to compare calcium absorption and bone growth in boys and girls on diets including either a nondigestible oligosaccharide (NDO) or simple sugar.
Read the detailed description
Rapid increases in bone mass occur during calcium absorption and bone calcium deposition during puberty, and these increases can enhance peak bone mass and ultimately decrease the lifetime risk of osteoporosis. However, dietary, hormonal, and genetic factors likely affect increased bone mass. This study will examine if adding NDO to a pubertal diet allows more absorption of calcium by the body, producing stronger bones. The study will also assess how the hormones produced by the body during puberty affect bone growth and whether genetic factors affect calcium absorption or bone growth.
This study will last 2 years. At study entry, baseline pubertal hormone levels and bone mass will be assessed. Both a dual-energy X-ray absorptiometry (DEXA) scan and a calcium stable kinetic study measuring calcium absorption will be performed. Participants will then be randomly assigned to receive calcium fortified food with or without added NDO for 1 year. Calcium absorption will be measured again at 2 months. After the first year, calcium kinetic, hormonal, and DEXA studies will be performed and compared to baseline results. A final DEXA scan will be performed at the end of 2 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Nondigestible oligosaccharide (NDO) in people with Osteoporosis and Osteopenia, run by Baylor College of Medicine at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 24 Jul 2015. 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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 NCT00022867, which also lists 4 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 24 Jul 2015.
