The primary objective of this study is to determine whether treatment with CEP-10953 is more effective than placebo treatment for patients with excessive sleepiness associated with narcolepsy by measuring mean sleep latency from the Maintenance of Wakefulness (MWT) (20-minute version)(average of 4 naps at 0900, 1100, 1300, and 1500) and by the Clinical Global Impressions of Change (CGI-C) ratings (as related to general condition) at week 12 (or last postbasline visit)
A 12-Week, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of CEP-10953 (150 and 250 mg/day) as Treatment for Adults with Excessive Daytime Sleepiness Associated with Narcolepsy
Treatment, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study
Study start: December 2003; Expected completion: September 2004
