Dietary Treatment Study of Pediatric NAFLD (DTS)

January 16, 2020 updated by: Jeffrey B. Schwimmer, MD, University of California, San Diego

Randomized, Controlled Dietary Treatment Study of Pediatric NAFLD

This is an investigator initiated study being conducted in equal numbers at two sites, University of California, San Diego (UC San Diego) and Emory University (EU). The purpose of this study is to understand the potential of a low sugar diet for the treatment of nonalcoholic fatty liver disease (NAFLD) in children. Forty boys with NAFLD will be randomly assigned to either an intervention group or a habitual diet control group. The intervention will be a low sugar diet for a period of 8 weeks. The effect of this dietary change will be assessed using advanced magnetic resonance imaging (MRI) testing to measure liver fat.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

11 years to 16 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

  • Written informed consent from parent or legal guardian.
  • Written informed assent from the child or adolescent.

Exclusion Criteria:

Exclusions will not be based upon gender, race, or ethnicity. Participants with a current history of the following conditions or any other health issues that make it unsafe for them to participate in the opinion of the Investigators will be excluded from the study:

  • Unable to have or complete the MRI exam due to body weight exceeding scanner table limit or girth exceeding scanner bore diameter
  • Subjects who are not able or willing to comply with the protocol or have any other condition that would impede compliance or hinder completion of the study, in the opinion of the investigator
  • Families with > 5 individuals
  • Failure to give informed consent

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Percentage of Liver Fat Measured by Magnetic Resonance Imaging (MRI) in the Intervention Group Compared to Change in the Control Group
Time Frame: Measurements done at baseline and week 8.
The principal objective of this randomized and controlled pilot study is to evaluate whether 8 weeks of a low added sugar diet (<3%) in boys with NAFLD will change liver fat % measured by MRI.
Measurements done at baseline and week 8.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
