Effect of Prebiotic Fiber- Enriched (scFOS) Enteral Feeding on the Microbiome in Neurological Injury Trauma Patients (PreFEED Microbiome Trial)

June 2, 2021 updated by: Duke University
This study plans to learn more about the impact of enteral nutrition on bacteria in critically ill trauma patients with brain injury. Specifically, it seeks to understand the effect that a prebiotic containing enteral feeding formula (Nutraflora scFOS in Vital AF) has on the gut, oral, and skin bacteria. A prebiotic is a special form of dietary fiber that acts as a fertilizer for good bacteria. The prebiotic Nutraflora scFOS has been cleared by the U.S. Food and Drug Administration and is not considered investigational as used in this study. Enteral feeding is a way to give nutrition to critically ill people who are unable to eat.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Adult major neurological injury trauma patients between 18-70 years of age who have been admitted directly to trauma ICU following major trauma
  2. Expected length of mechanical ventilation > 48 hours (as judged by admitting clinician)
  3. Expected length of ICU stay > 3 days (as judged by admitting clinician)
  4. Expected to survive > 48 hours (as judged by admitting clinician)
  5. Requiring enteral nutrition at any time in Intensive Care Unit (ICU) stay
  6. Chronic illnesses must be under control (as determined by the Principal Investigator).

Exclusion Criteria:

  1. Previous hospitalization within one month prior to ICU admission (no hospital floor transfers to eliminate confounding effect of previous hospital therapy)
  2. Use of prebiotic fiber containing enteral or oral formula or probiotic preparations within one week
  3. Received antibiotics within the previous month
  4. On steroids or immunosuppressants at time of admission
  5. All transplant patients
  6. Chronic inflammatory disease that requires steroids or other biologic therapy intervention (e.g.: RA, IBD that requires steroids or Humira)
  7. Undergoing active chemotherapy/radiation treatment
  8. Renal failure requiring dialysis
  9. Liver cirrhosis class C

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.
