Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Definition of fatigue according to the MS Council for Clinical Practice Guidelines is as follows: "A subjective lack of physical and/or mental energy that is perceived by the individual or caregiver to interfere with usual and desired activities".
As fatigue is a subjective and non-specific symptom, and can easily be confused with either weakness or depressed mood, both common in MS, the following characteristics have been defined to better diagnose MS-associated fatigue:
* MS-related fatigue generally occurs on a daily basis.
* It tends to worsen as the day progresses.
* It tends to be aggravated by heat and humidity.
* It is not directly correlated with either depression or the degree of physical impairment.
* It may occur first thing in the morning even if the patient has had a restful full night's sleep.
The current medications used for the treatment of MS-associated fatigue such as amantadine hydrochloride and pemoline are useful to some, but not all patients. In a multicenter trial (2) it was found that 100 mg amantadine twice daily significantly improves fatigue. Pemoline in a placebo-controlled trial (3) failed to show significant effect on fatigue in MS patients and was poorly tolerated as side effects occurred in 25% of patients. A third trial (4) compared pemoline to amantadine and placebo, and showed only a positive trend for pemoline, while amantadine had a benefit over placebo in some fatigue measures. There was also a marked placebo effect in this trial, with approximately half of patients reporting improvement in fatigue no matter what treatment (pemoline, amantadine or placebo) they were taking.
In the current study proposal we intend to evaluate the effect of Provigil on MS-associated fatigue.
The possibility for add-on drug that will affect fatigue in MS is of importance, as fatigue has a significant impact on activities of daily living, interfering with work, family life and social activities.
1.2. The fatigue scale named "Fatigue Impact Scale" The awareness of the impact of fatigue on patient's quality of life (QOL) and the need to evaluate the effect of the different therapies on this parameter resulted in the development and validation of different questionnaires for the measurement of fatigue, i.e., the Fatigue Impact Scale (FIS), which has been shown to measure both, fatigue and treatment effect on fatigue (6-9).
The FIS is a reliable and validated 40-items questionnaire that is capable of selecting a treatment effect. It is a made up of 3 sub-scales: physical, cognitive and social. Each question is scored from 0-4, allowing a total score of 160. High scores indicate high impairment.
