Cephalon Announces Positive Topline Results From a Phase IV Study of NUVIGIL in Shift Work Disorder

Study Focuses on Efficacy of NUVIGIL Late in Shifts, Including Commute Home

FRAZER, Pa., Jan. 25, 2011 /PRNewswire/ -- Cephalon, Inc. (Nasdaq: CEPH) today announced positive results from a phase IV clinical trial of NUVIGIL® (armodafinil) Tablets [C-IV] in patients experiencing excessive sleepiness associated with shift work disorder, specifically during the end of their night shifts (i.e., 4:00 a.m. to 8:00 a.m.), including the commute home. The study data showed statistically significant difference in improvement in overall clinical condition related to late-shift sleepiness in patients receiving NUVIGIL compared to the placebo group. This is the largest trial ever conducted in this patient population, with more than 380 patients randomized to treatment with NUVIGIL or placebo.

The primary outcome measure of this six-week, multicenter, double-blind study of NUVIGIL (150 mg) was the Clinical Global Impression of Change (CGI-C) scale. The CGI-C in this study asked that the clinician rate the patient's improvement in overall clinical condition as it related to sleepiness with shift work disorder late in the shift. Using this rating, the percentage of patients taking NUVIGIL who experienced improvement from baseline was 77 percent versus 57 percent for placebo (p<0.0001). The key secondary outcome was measured using the Global Assessment of Functioning (GAF), a well-recognized assessment of patient functioning found in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Patients receiving NUVIGIL showed a 9.5 point improvement over baseline in the GAF versus a 5.2 point improvement in the placebo group (p< 0.0001).

The most frequently reported adverse events in this study are consistent with those described in the NUVIGIL prescribing information, and include headache, nausea, and insomnia. There were no serious adverse events observed in patients taking NUVIGIL in this study. The first presentation of these data will occur during the Society of General Internal Medicine's 34th Annual Meeting in May 2011. Additional results also will be submitted for future publications and presented at medical meetings.

According to the U.S. Department of Labor, over 15 million Americans work odd hours or non-traditional shifts, and are "at risk" for shift work disorder. Shift work disorder occurs when the body's internal sleep-wake clock is out of sync with the individual's work schedule -- their body is telling them to go to sleep when their work schedule needs them to stay awake. Because of this disruption of the body's natural rhythm, people with shift work disorder often struggle to stay awake during their waking hours (excessive sleepiness), or have trouble sleeping during their sleeping hours (insomnia).


NUVIGIL is indicated to improve wakefulness in patients with excessive sleepiness associated with treated obstructive sleep apnea (OSA), shift work disorder (SWD), or narcolepsy. In patients with OSA, NUVIGIL is used along with other medical treatments for this condition. The NUVIGIL (armodafinil) label includes a bolded warning for serious or life-threatening rash, including Stevens-Johnson Syndrome, requiring hospitalization and discontinuation of treatment, that has been reported in adults in association with the use of modafinil and armodafinil and in children in association with the use of modafinil, a racemic mixture of S and R modafinil (the latter is armodafinil, the active ingredient in NUVIGIL). NUVIGIL is not approved for use in pediatric patients for any indication.

The most common adverse events in controlled clinical trials (five percent or greater) were headache, nausea, dizziness, and insomnia. Full prescribing information for NUVIGIL is available at .
