MitoQ for Fatigue in Multiple Sclerosis (MS)

Phase 1

Active, not recruiting

• Conditions: Fatigue; Multiple Sclerosis
• Interventions: Drug: Placebo; Drug: 20 mg MitoQ; Drug: 40mg of MitoQ

• Registration Number: NCT04267926
• Lead Sponsor: VA Office of Research and Development

Brief Summary

The purpose of this study is to determine whether MS patients who receive Oral mitoquinone (MitoQ) have less fatigue than those receiving a placebo. A comparison between patient's fatigue scored at baseline and fatigue scored 12 weeks after drug initiation will assess if MitoQ has a significant change in fatigue.

Detailed Description

Recruitment of subjects on hold due to COVID-19 pandemic

MitoQ is a potent antioxidant dietary supplement with potentially significant immunomodulatory and anti-inflammatory properties. While the cause of MS related fatigue is uncertain, the investigators believe that mitochondria dysfunction and resultant neuronal energy depletion may be an important contributor to fatigue in MS.

This clinical trial will evaluate the potential beneficial effects of MitoQ on MS fatigue. It will also explore the effects of MitoQ on cognitive function, quality of life and mood. If enrolled in the study, patients will take two capsules of the study drug or placebo at the same time every day for twelve weeks. There will be 4 study visits where the participant will undergo medical and nervous system examinations, questionnaires, and blood draws. Because it is a placebo-controlled trial, participants will have a 33% chance of receiving either placebo (inactive), 20mg of MitoQ, or 40mg of MitoQ. This will be a blinded randomized study, meaning neither the participant nor the investigator will know who received the placebo or study drug.
