About this study

Official title: Probiotics (VSL #3) for Gulf War Illness

The overall objective is to determine whether VSL #3 will improve 1) intestinal symptoms of Irritable Bowel Syndrome (IBS) and 2) non-intestinal symptoms (fatigue, joint pain, insomnia, general stiffness and headache) associated with IBS. All of these symptoms are part of the Gulf War (GW) illness.

Read the detailed description

Specific Aims:

Aim # 1: Determine the efficacy of VSL #3 on IBS symptoms in GW veterans.

Hypothesis: Treatment with VSL #3 compared to placebo will improve global and individual symptoms of IBS

Aim #2 Determine the efficacy VSL #3 in reducing non-intestinal symptoms of IBS (fatigue, joint pain, insomnia, general stiffness and headache).

Hypothesis: Treatment with VSL #3 compared to placebo will improve non-intestinal symptoms of IBS in GW veterans.

Aim #3 Determine whether changes in gut flora and plasma cytokines correlate with treatment response in GW veterans.

What is being measured

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

  1. Improvement in the Bowel Symptom Scale (BSS) From Baseline

    Efficacy of VSL #3 in Irritable Bowel Syndrome (IBS) related symptoms in Gulf War illness is measured using BSS at 2, 4, 6, 8 wks

    Measured: 8 weeks

Secondary outcomes (1)
  1. Change in Chronic Fatigue (1-5 Scale) From Baseline

    Efficacy of VSL #3 in reducing non-intestinal symptoms of IBS is measured using chronic fatigue scale at 2,4,6,8, weeks

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing VSL#3 in people with Gulf War Illness, run by University of Utah 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 9 inclusion and 11 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: stopped early, as of the sponsor's last update on 26 Oct 2018. 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 combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 16 Jan 2018). 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?

Improvement in the Bowel Symptom Scale (BSS) From Baseline (time frame: 8 weeks). 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 26 Oct 2018; AzTrials last refreshed its copy on 30 Oct 2026.
