Brief Summary

Multiple sclerosis (MS) is an inflammatory, demyelinating and degenerative disease of the central nervous system and, after trauma, is the most common cause of disability in young adults, affecting more than 400,000 individuals in the US. Of all the symptoms that can occur with MS, chronic fatigue is the most common and disabling, reported by at least 75% of patients at some point. Fatigue limits patients' daily activities, and challenges employment, resulting in substantial socioeconomic consequences. Despite this negative impact, fatigue treatments have been inconsistently studied, in part due to poorly understood underlying pathophysiological mechanisms. Yet to be defined biological processes and lack of clear treatment targets have also hampered the development of drugs for fatigue. As a result, there are no medications approved by the Food and Drug Administration (FDA) for the treatment of MS fatigue. The investigators recently reported that riluzole, a medication with anti-glutamatergic effects, increased the fatigue severity in patients with relapsing MS who had participated in a clinical trial evaluating potential neuroprotective effects of riluzole versus placebo. Three other clinic trials which examined memantine effects on cognition in patient with MS also reported worsening fatigue as a major side effect. Memantine main mechanism of action is blocking the N-methyl D-aspartate (NMDA) glutamate receptor. These observations prompted the investigators that glutamatergic transmission probably plays an important role in fatigue pathogenesis and modulating these pathways could have potential therapeutic effect on MS-related fatigue. A recent paper reported that ketamine, an NMDA receptor blocker with different kinetics compared to memantine, had a strong and prolonged effect in reducing fatigue in bipolar patients who participated in a clinical trial, evaluating anti-depressive effects of ketamine versus placebo. Interestingly, the effect of ketamine on fatigue was independent of its antidepressant effects. The primary objective of this study is to determine if modulating glutamatergic transmission with ketamine is safe and efficacious in improving MS-related fatigue. These objectives will be answered in a proof of concept, randomized controlled trial of ketamine versus an active placebo (midazolam) in patients with relapsing or progressive MS who have clinically significant fatigue. 18 patients with MS and reported fatigue, will be randomized 2:1 to one infusion of ketamine 0.5 mg/kg over 40 minutes versus one infusion of midazolam 0.05 mg/kg over 40 minutes. Midazolam is chosen as an active placebo to keep the participants blinded to participants' medication assignment. Primary outcome of the study will be Daily Fatigue Severity measured daily from day one through day seven post-infusion. Secondary outcomes of the study include other fatigue questionnaires, depression and sleepiness. The length of study will be around 28 days.

Outcome Measures

Primary Outcomes (1)

  • Change in Daily Fatigue Severity Score

    It is a single item question: 'how much fatigue (tiredness, weariness, problems thinking clearly) have you felt today?' with responses from 0 'None at all' to 10 'Extreme Fatigue'. Reported score changes are the average point/day score change. The mean score is reported based on this calculation: \[(last day measure - baseline measure) / the number of days in the study\].

    Baseline (infusion visit) through day 7

Secondary Outcomes (5)

  • Change in Quality of Life in Neurological Disorders (NeuroQol) Fatigue Item Bank Score

    Baseline (infusion visit) through day 28 post-infusion

  • Change in Modified Fatigue Impact Scale (MFIS) Score

    Baseline (infusion visit) through Day 28 post-infusion

  • Change in Epworth Sleepiness Scale Score

    Baseline (infusion visit) through day 28 post-infusion

  • Change in Beck Depression Inventory (BDI) Score

    Baseline (infusion visit) through day 28 post-infusion

  • Change in Fatigue Severity Scale (FSS) Score

    Baseline (infusion visit) through day 28 post-infusion
