Brief Summary:
The purpose of this study is to determine whether methylphenidate is effective in the treatment of excessive daytime sleepiness due to myotonic dystrophy type 1 (DM1).

Condition or disease Intervention/treatment Phase
Dystrophia Myotonica 1 Drug: Methylphenidate Drug: Placebo Phase 2 Phase 3

Detailed Description:
Myotonic dystrophy type 1 (DM1) is a multisystemic disorder characterized by muscle weakness, myotonia, and the involvement of several systems. Hypersomnolence is one of the most frequently reported symptoms in patients with DM1 and often lead to handicap such as cessation of employment and withdrawal from social activities.The current investigation represents a prospective, double-blind, randomized, crossover, placebo-controlled study designed to evaluate the efficacy of methylphenidate for the treatment of excessive daytime sleepiness (EDS) in adults with DM1.

Official Title: Phase 2/3 Study of Efficacy and Tolerability of Methylphenidate in the Treatment of Excessive Daytime Sleepiness in Myotonic Dystrophy Type 1
Study Start Date : June 2008
Actual Primary Completion Date : August 2010
Actual Study Completion Date : September 2010

Arm Intervention/treatment
Placebo Comparator: Arm 1: Methylphenidate versus baseline Drug: Methylphenidate
One Tablet of methylphenidate, 20 mg per day during 3 weeks
Other Name: Ritalin

Placebo Comparator: Arm 2: Placebo versus baseline
One table placebo per day during 3 week
Drug: Placebo
one tablet placebo per day during 3 weeks

Primary Outcome Measures :
  1. Change from baseline of excessive daytime sleepiness [ Time Frame: 3 weeks after treatment ]
