About this study

Official title: The Effect of an Enhanced Rice Bran Nutritional Supplement on Non-Alcoholic Fatty Liver Disease (NAFLD)

The purpose of this study is to investigate the effects of Rice Bran Arabinoxylan Compound (RBAC) on outcome variables in persons with non-alcoholic fatty liver disease (NAFLD). This nutritional supplement is made from a water soluble extract of rice bran that has been partially hydrolyzed by the action of a natural enzyme complex extracted from Shiitake mushroom.

Read the detailed description

The purpose of this study is to investigate the effects of Rice Bran Arabinoxylan Compound (RBAC) on outcome variables in persons with non-alcoholic fatty liver disease (NAFLD). This nutritional supplement is made from a water soluble extract of rice bran that has been partially hydrolyzed by the action of a natural enzyme complex extracted from Shiitake mushroom. Given that these micronutrients may be important for regulating the immune system, investigators will investigate the impact of RBAC on the following variables among 20 adults (18+ years of age and over) diagnosed with NAFLD:

  1. albumin
  2. 4-hydroxynonenal
  3. lipids
  4. liver enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP)
  5. malondialdehyde
  6. γ-glutamyltransferase
  7. cytokines (TNF-α, LT-α, IL-1α, IL-1β, IL-6, TNF-RI, TNF-RII, IFN-γ, IL-12, IL-2, IL-15, IL-8, IL-4, IL-5, IL-17, IL-23, IL-10, IL-13, and IL-18)
  8. lymphocytes
  9. platelets

Specifically, subjects will participate in a 3-month, two-group, randomized intervention, where one group (n=10) will take 1 gram/day RBAC and the other group (n=10) will take a placebo to compare differences in outcomes between the two groups. The results of the study are intended to address the multi-faceted physiological problems of NAFLD patients by testing the efficacy of a nutritional supplement intervention on multiple outcomes in this population.

What is being measured

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

  1. Change from baseline in liver function test

    Liver function tests as defined by serum ALT, AST and ALP

    Measured: Baseline, 45 days and 90 days

  2. Change from baseline in metabolic markers

    Metabolic markers as defined by lipid profile

    Measured: Baseline,45 days and 90 days

  3. Change from baseline in immunological markers

    Immunological markers as defined by TNF-α, LT-α, IL-1α, IL-1β, IL-6, TNF RI, IFN-γ, IL-12, IL-2, IL-15, IL-8, TNF RII, IL-4, IL-5, IL-17, IL-23, IL-10, IL-13, and IL-18.

    Measured: Baseline,45 days and, 3 months

Secondary outcomes (4)
  1. Change from baseline in systolic blood pressure

    Systolic blood pressure will be measured to the nearest even digit by use of the Microlife Deluxe upper arm blood pressure monitor. Three readings will be made with the subjects seated after they have rested for five minutes. The average of the three readings will be used in the analysis.

    Measured: Baseline,45 days and 3 months

  2. Change from baseline in Diastolic blood pressure

    Diastolic blood pressure will be measured to the nearest even digit by use of the Microlife Deluxe upper arm blood pressure monitor. Three readings will be made with the subjects seated after they have rested for five minutes. The average of the three readings will be used in the analysis.

    Measured: 45 days and 90 days

  3. Pulse

    Pulse will be measured to the nearest even digit by use of the Microlife Deluxe upper arm blood pressure monitor. Three readings will be made with the subjects seated after they have rested for five minutes. The average of the three readings will be used in the analysis.

    Measured: Baseline,45 days and 3 months

  4. Change from Baseline in Quality of Life

    The SF-36v2™ Health Survey (15) provides psychometrically-based physical and mental health summary measures and a preference-based health utility index. It is a generic measure that does not target a specific age, disease, or treatment group.

    Measured: Baseline,45 days and 3 months

The record says: finished, as of the sponsor's last update on 14 Jun 2017. 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.

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.

What does the primary outcome measure?

Change from baseline in liver function test (time frame: Baseline, 45 days and 90 days). The study lists 3 primary outcomes in all. 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 NCT02568787, which also lists 15 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 14 Jun 2017.
