Brief Summary:
The project will improve scientific knowledge regarding a recent law applying potentially to every french driver. It will give for the first time an indication on the impact of alerting treatments on driving risks. It will reinforce the links between different research environments (sleep physiopathology, clinical research, cognitive neurosciences, driver's supervision, virtual reality, pharmacology) among the RESAT network (Réseau Eveil Sommeil Attention Transport). It will stimulate data acquisition in technological research to better understand the difference between real and simulated driving

Condition or disease Intervention/treatment Phase
Narcolepsy Hypersomnia Drug: Modafinil Drug: Placebo Not Applicable

Detailed Description:
Excessive daytime sleepiness is responsible of 20% of traffic accidents and 2/3 of truck accidents on French Freeways. Since the publication of a new law (arrêté du 28 décembre 2005 du journal officiel) regulating fitness to drive, the Maintenance of Wakefulness Test (MWT) is now mandatory to evaluate driving skills of patients suffering of excessive daytime sleepiness. The MWT has shown a good predictability of driving handicap on simulators in patients suffering from obstructive sleep apnea syndrome. Nevertheless no study has proven yet the predictability of the MWT regarding real and simulated driving in narcoleptics and hypersomniacs. Furthermore, even if alerting drugs significantly improve MWT scores there is no data available concerning the impact of these drugs on fitness to drive. This lack of knowledge is a major handicap to evaluate driving skills of treated patients suffering from excessive daytime sleepiness. The main objective of our project is to test the predictive value of the MWT on real and simulated driving performances in untreated and treated sleepy patients suffering from narcolepsy and hypersomnia. Inclusion of healthy volunteers will allow to collect reference data about somnolence during MWT.

Arm Intervention/treatment
Experimental: Modafinil First
Treatment by Modafinil during first condition then placebo during second condition
 Drug: Modafinil

Modafinil is taken by narcoleptics or hypersomniacs during 5 successive days, twice a day (at the breakfast and at the lunch):

  • during 3 days at home
  • during the period of 2 nights and 2 successive days of hospitalization in order to realise a Maintenance of Wakefulness Test the first day and 2 driving sessions (one simulated driving during the morning and one real driving during the afternoon) of 2 hours each the day after, under treatment (Modafinil).

Drug: Placebo

Placebo is taken by narcoleptics or hypersomniacs during 5 successive days, twice a day (at the breakfast and at the lunch):

  • during 3 days at home
  • during the period of 2 nights and 2 successive days of hospitalization in order to realise a Maintenance of Wakefulness Test the first day, and 2 driving sessions ( one simulated driving during the morning and one real driving during the afternoon) of 2 hours each the day after, under Placebo.
Experimental: Placebo First
Treatment by Placebo during first condition then Modafinil during second condition
 Drug: Modafinil

Modafinil is taken by narcoleptics or hypersomniacs during 5 successive days, twice a day (at the breakfast and at the lunch):

  • during 3 days at home
  • during the period of 2 nights and 2 successive days of hospitalization in order to realise a Maintenance of Wakefulness Test the first day and 2 driving sessions (one simulated driving during the morning and one real driving during the afternoon) of 2 hours each the day after, under treatment (Modafinil).

Drug: Placebo

Placebo is taken by narcoleptics or hypersomniacs during 5 successive days, twice a day (at the breakfast and at the lunch):

  • during 3 days at home
  • during the period of 2 nights and 2 successive days of hospitalization in order to realise a Maintenance of Wakefulness Test the first day, and 2 driving sessions ( one simulated driving during the morning and one real driving during the afternoon) of 2 hours each the day after, under Placebo.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Sleep latency during MWT, number of vehicle's line crossing on the road, standard deviation of the vehicle's position on the road [ Time Frame: for each condition, at day 4 for patients or day 1 for healthy volonteers ]

Secondary Outcome Measures :
  1. Subjective sleepiness (Karolinska and VAS scales) [ Time Frame: for each condition, at day 4 and 5 for patients or day 1 for healthy volonteers ]
  2. nocturnal sleep quality and quantity will be measured by PSG and Actimetry. [ Time Frame: For each condition, at day 4 and 5 for patients or day 1 for healthy volonteers ]
