About this study

Official title: The Use of High Bile-Binding Foods to Reduce Upper Gastrointestinal Bile Acid Concentrations: A Novel Intervention for Children at Risk for Aspiration-Associated Complications (Aim 1)

We will perform an acute physiology study comparing three different diets-an amino acid-based formula, a low bile acid-binding blenderized diet, or a high bile acid-binding blenderized diet administered through gastrostomy tube. We will determine the differences in gastric and salivary bile acid concentrations between participants over the 4 hour post-prandial timeframe.

Participants who regularly receive an amino acid-based formula will receive an amino acid-based formula during the study and participants who regularly receive a blenderized feed will receive a blenderized feed during the study. Only participants who regularly receive blenderized feeds will be randomized to receive either the high or low bile acid binding blenderized feed.

Being tested
amino acid based formula (e.g. Elecare Jr), low bile acid binding blenderized diet (e.g. Kate Farms), high bile acid binding blenderized diet
Keywords
blenderized, bile acid, gastrostomy, aspiration

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    We will administer one bolus of an amino acid based formula

  • low bile acid binding blenderized diet (e.g. Kate Farms)Drug

    We will administer one bolus of a low bile acid binding blenderized diet

  • high bile acid binding blenderized dietDrug

    We will administer one bolus of a high bile acid binding blenderized diet

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Gastric bile acid concentration

    Mean difference in gastric bile acid concentrations between start of feed and four hours following feed

    Measured: 4 hours

Secondary outcomes (5)
  1. Gastric bile acid concentration

    Differences in gastric bile acid concentrations from start of feed to 1, 2 and 3 hours after feed between groups

    Measured: 1, 2 and 3 hours

  2. Correlations between gastric bile acid and gastroesophageal reflux Likert scale

    Correlations between the postprandial changes in gastric bile acid concentrations and gastroesophageal reflux Likert scores

    Measured: Baseline to 1, 2, 3 and 4 hours post-prandial

  3. Correlation of symptom scores with gastric and salivary bile acid concentration

    comparison of PedsGIQL scores, GERD Likert scores, and PC-QoL scores with baseline gastric and salivary bile acid concentrations

    Measured: baseline

  4. Correlation of gastric and salivary bile acid concentrations

    correlations between gastric and salivary bile acid concentrations at each time point

    Measured: 0, 1, 2, 3 and 4 hours post-prandial

  5. correlations between C13 excretion rates and gastric and salivary bile acid concentrations

    correlations between C13 excretion rates and gastric and salivary bile acid concentrations

    Measured: Baseline to 1, 2, 3 and 4 hours post-prandial

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing amino acid based formula (e.g. Elecare Jr), low bile acid binding blenderized diet (e.g. Kate Farms) and high bile acid binding blenderized diet in people with Feeding Difficulties and Aspiration, run by Boston Children's Hospital 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 3 inclusion and 5 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: looking for participants now, as of the sponsor's last update on 3 Aug 2026. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Rachel Rosen (617-355-0897, rachel.rosen@childrens.harvard.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Gastric bile acid concentration (time frame: 4 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 3 Aug 2026.
