MitoQ for Fatigue in Multiple Sclerosis

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.
