Detailed Description:

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by resting tremor, rigidity, bradykinesia and loss of postural reflexes that affects 1% of the North American population. Besides these motor problems there are also so called non-motor problems.

Excessive daytime sleepiness (EDS) is a bothersome non-motor problem, which affects 20% to 50% of all PD patients and currently, there isn't any registered treatment for that trouble.

The study medication BF2.649 tested here is a novel, highly potent, selective, orally active inverse agonist at the histamine H3 receptor, therefore strengthens histaminergic transmission in the brain and increases wakefulness EDS is characterized by daytime somnolence and sudden sleep episodes. This problem has several consequences, e.g., an impairment of quality of life, an interference with activities of daily living and other handicaps in the management of social and family affairs.

The primary endpoint of this study will be measured by the change in the well-validated Epworth sleepiness scale (ESS). The ESS is a simple self-administered 8-item questionnaire. The outcome is to get an impression about the level of the daytime sleepiness in several real-life situations.

On the basis of this pharmacological and clinical rationale it is considered relevant to carry out a dose-finding study for this original, non-amphetamine molecule in PD patients affected by excessive daytime sleepiness. PD severity will be assessed by the routinely used UPDRS.
