About this study

The primary aim of this proposal is to determine the effects of soluble corn fiber (SCF) supplementation for 1 year on bone metabolism in growing adolescents compared to controls. For the proposed study, a randomized double-blinded placebo controlled clinical trial will be conducted in 236 healthy adolescents aged 10-13 years, equally randomly assigned to one of four intervention groups: SCF (12 g/d), SCF + calcium (12 g/d of SCF + 600 mg/d of elemental calcium), placebo (0 g/d of SCF or of calcium), and placebo + calcium (0 g/d of SCF + 600 mg/d of elemental calcium); all administered twice a day. Bone mass will be assessed at baseline at 6 months and at 12 months and bone related biomarkers and fecal microbiome will be assessed at baseline and at 12 months.

Read the detailed description

The adolescent period is crucial for optimizing future bone health because bone accumulates rapidly during these years and accounts for up to half of adult peak bone mass. Calcium intake during this period is critical for adequate bone mineralization but this is the nutrient most deficient in the diets of adolescents. A strategy to maximize bone mineralization during this critical period is to increase the absorption of the calcium being consumed. This could be achieved by supplementing diets with certain non-digestible carbohydrates, such as soluble corn fiber (SCF).

The primary aim of this study is to determine the effects of SCF supplementation for 1 year on bone metabolism in growing adolescents compared to controls. A randomized double-blinded placebo controlled clinical trial will be conducted in 236 healthy adolescents aged 10-13 years, equally randomly assigned to one of four intervention groups: SCF (12 g/d), SCF + calcium (12 g/d of SCF + 600 mg/d of elemental calcium), placebo (0 g/d of SCF or of calcium), and placebo + calcium (0 g/d of SCF + 600 mg/d of elemental calcium); all administered twice a day. Bone mass will be assessed at baseline at 6 months and at 12 months and bone related biomarkers and fecal microbiome will be assessed at baseline and at 12 months. The treatments will be provided in the form of flavored drinks twice per day (this was previously used in a short-term study among adolescents with excellent acceptance). Bone mass and anthropometric measurements will be assessed at baseline, at 6 months and at 12 months and bone related biomarkers and fecal microbiome will be assessed at baseline and at 12 months. Assessment visits will be conducted in the Clinical Research Center of the Stempel School of Public Health at Florida International University. We will also have short home visits at 3 and 9 months to collect unused supplements and provide more supplements. In all visits, participants will complete several questionnaires, such as general health, diet and activity questionnaire. Compliance will be evaluated at all visits and also in real time using a study mobile app.

The primary outcome is change in bone mineral content (BMC) measured using Dual-energy X-ray absorptiometry (DXA)

The secondary outcomes include biochemical markers reflecting vitamin D status, calcium homeostasis and bone, such as serum calcium, phosphorus, creatinine, osteocalcin, carboxy-terminal collagen crosslinks (CTX), parathyroid hormone (PTH), bone specific alkaline phosphatase, 25-(OH) vitamin D3, 1,25-(OH)2 vitamin D3, and insulin growth factor 1 (IGF-I) and urinary calcium, phosphorus, creatinine and N-telopeptide cross-links.

A Phase 2 study testing Soluble Corn Fiber (SCF) without Calcium and Soluble Corn Fiber (SCF) + Calcium in people with Osteoporosis, run by Florida International University 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?

The sponsor lists 1 inclusion and 2 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 10 Nov 2025. 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 29 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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.

What does the primary outcome measure?

Change in Whole Body Bone Mineral Content (BMC) (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02916862, which also lists 2 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 10 Nov 2025.
