Modafinil for the treatment of hypersomnia associated with myotonic muscular dystrophy in adults: a multicenter, prospective, randomized, double-blind, placebo-controlled, 4-week trial.

AbstractBACKGROUND:
Myotonic muscular dystrophy type 1 (MMD1) is the most common form of adult MD, with a mean prevalence of 1 in 8000. Excessive daytime sleepiness (ie, hypersomnia) is a common complication of MMD1.
OBJECTIVE:
The aim of this study was to evaluate the efficacy and tolerability of modafinil for the treatment of hypersomnia in adults with MMD1.
METHODS:
This multicenter, prospective, randomized, double-blind, placebo-controlled study consisted of a prerandomization period (90 to 2 days before randomization) and a 4-week randomization period in which patients were assigned to receive either active treatment (modafinil 300 mg/d) or placebo. The study was conducted at 3 clinics in France between February 2000 and June 2002. Adult patients aged > or =18 years, with genetically proven MMD1, an Epworth Sleepiness Scale (ESS) score >10, and a mean latency to sleep onset < or =8 minutes measured by the Multiple Sleep Latency Test (MSLT) were eligible. The primary efficacy end point was the Maintenance of Wakefulness Test (MWT) score at 4 weeks. Secondary end points included the mean MSLT score and scores from the ESS, physician's assessment of the therapeutic effect and the patient's global self-assessment via visual analog scale, the 17-item Hamilton Depression Rating Scale, and the Short Form Health Survey (SF-36) quality-of-life assessment.
RESULTS:
A total of 28 patients (15 men, 13 women; mean [SD] age, 40 [12.7] years [range, 18-69 years]; 100% white; modafinil group, 13; placebo group, 15) completed the study without protocol violations. Of the 28 patients with MMD1 included in the analysis, 21 had adult-onset MMD1. At 4 weeks, the mean MWT score was 16.4 (3.3) minutes in the modafinil group and 15.8 (3.8) minutes in the placebo group (P = NS). At the end of the randomization period, there were no significant between-group differences in any secondary outcome. A total of 8 patients (4 in each group) reported > or =1 adverse event, including digestive, neurologic, and skin symptoms. Weight loss was reported in 1 patient (2 kg).
CONCLUSION:
In this small study conducted in an adult population with MMD1 and a high prevalence of hyper-somnia, modafinil had no significant effects on daytime somnolence measured using objective MWTs.
