E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Fatigue is a very common symptom in multiple sclerosis. Its management comprises nonpharmacologic approaches like exercise, cooling procedures and energy conservation programs and as second step pharmacologic therapy. Until now, Amantadine, Modafinil or antidepressants have been used off-label among others, with some success. Until now, methylphenidate has been successfully used to treat fatigue in HIV and parkinson´s disease, data on its efficacy in MS are not available.

Für die Therapie der bei Multipler Sklerose häufigen Fatigue stehen wenige Maßnahmen zur Verfügung. Zuerst werden den Patienten konservative Strategien empfohlen und der Einsatz von Medikamenten erfolgt erst sekundär. Folgende Medikamente können hilfreich sein (off-label): Amantadin,Modafinil oder Antidepressiva. Die Wirksamkeit von retardiertem Methylphenidat gegen Fatigue wurde bei Morbus Parkinson und HIV in Studien bestätigt. Zum Einsatz gegen MS-assoziierte Fatigue gibt es keine Daten. |

E.1.1.1 | Medical condition in easily understood language |
Fatigue is a common symptom in multiple sclerosis that is often difficult to treat. It is characterised by a physical and/or mental exhaustion. |
Bei Multipler Sklerose kommt es häufig zu einer verstärkten Ermüdbarkeit und Erschöpfbarkeit, deren medikamentöse Behandlung oftmals schwierig ist. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The goal of our study is to determine the efficacy of methylphenidate in reducing fatigue in subjects with Multiple sclerosis. The question of whether MS‐associated fatigue improves after 6 weeks of methylphenidate therapy compared to baseline as measeured by Fatigue severity scale comprises the primary objective of our study.
|
primärer Endpunkt: Verbesserung der Fatigue nach 6 Wochen Therapie gemessen anhand der Fatigue Severity Scale. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to evaluate the efficacy of methylphenidate on fatigue in subjects with MS as measured by MFIS (modified fatigue impact scale) and VAS (visual analogue scale), on quality of life as measured by HAQUAMS (Hamburger Lebensqualitätsfragebogen) and on quality of sleep as measured by Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index. An objetive assessment of fatigue will be done by neuropsychological TAP (test for attentional performance -subscale alertness and divided attention). |
sekundäre Endpunkte: Verbesserung von Fatigue nach 6 Wochen Therapie gemessen mittels modifizierter Fatigue Impact Scale und Visueller Analogskala. Weiters Einfluss auf die Lebensqualität erhoben mittels Hamburger Lebensqualitätsfragebogen und Einfluss auf Schlafqualität mittels Epworth Sleepiness Scale und Pittsburgh Sleep Quality Index.
