Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are veterans who were deployed during the Gulf War and meet the criteria for Chronic Multisymptom Illness.

Probably not a fit

Patients who are not veterans of the Gulf War or do not meet the specific diagnostic criteria for GWI may not benefit from this study.

What this trial studies

This multi-site clinical trial aims to evaluate the effectiveness of 300 mg of Nicotinamide Riboside (NR) in increasing plasma NAD+ levels in veterans suffering from Gulf War Illness (GWI). Utilizing a randomized, double-blind, placebo-controlled design, the study will assess whether NR supplementation can alleviate symptoms associated with GWI, such as fatigue and memory impairment. The trial is based on previous findings that indicate lower NAD+ levels in GWI patients compared to healthy controls, suggesting a potential bioenergetic deficit. Participants will be closely monitored for safety and efficacy throughout the study duration.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for veterans suffering from Gulf War Illness by alleviating debilitating symptoms.

How similar studies have gone: While the approach of using Nicotinamide Riboside is promising, it is relatively novel in the context of Gulf War Illness, with limited prior studies specifically targeting this condition.

* Have contraindications, allergy, or sensitivity to NR, vitamin B3, or excipients (microcrystalline cellulose, silicon dioxide, magnesium stearate, hypromellose, and/or titanium dioxide).
* Any significant medical condition that could interfere with study conduct, as per investigator discretion. These may include but are not limited to the following: untreated chronic hypertension (defined as systolic \> 180 mmHg; diastolic \>110 mmHg), myocardial infarction within 6 months of screening, renal failure, hepatic failure, and/or receiving chemotherapy.
* Clinically significant lab values for clinical laboratory assessments, as per investigator discretion.
* Poor venous access.
* Current use of any NR supplement products (such as nicotinamide, nicotinamide mononucleotide (NMN), vitamin B3/Niacin, vitamin B complex, etc.) within 30 days of screening.
