NUVIGIL Improved Wakefulness Throughout the Day

Patients with excessive sleepiness (ES) associated with narcolepsy taking NUVIGIL experienced significant improvement in wakefulness throughout the day1,2

Primary efficacy measure was the Maintenance of Wakefulness Test (MWT).1

WAKEFULNESS THROUGHOUT THE DAY (9 AM TO 3 PM)* †
Primary Endpoint

*
The MWT is an objective assessment of sleepiness that measures the ability of a subject to remain awake. Longer latencies indicate a greater ability to remain awake. Each test session was terminated after 30 minutes if no sleep occurred or immediately after sleep onset.

Average of 4 evaluations from 9 AM to 3 PM. N values shown represent the number of patients included in the efficacy analysis.
  • Patients should be advised that their level of wakefulness may not return to normal. Patients should be frequently reassessed for their degree of sleepiness and, if appropriate, advised to avoid driving or any other potentially dangerous activity

NUVIGIL Demonstrated Improvement in Overall Condition as Measured by the Clinical Global Impression of Change (Primary Endpoint)1-3

  • 73% of patients taking NUVIGIL 250 mg (n=60) and 69% of patients taking NUVIGIL 150 mg (n=58) improved at final visit compared to 33% of patients taking placebo (n=58) — a significantly greater improvement (P<0.05)
    • Physicians were asked to respond to the following question:

      "Compared to the patient's condition AT THE END OF THE SCREENING PERIOD, how much has the patient changed? (Rate total improvement, whether or not, in your judgement, it is entirely due to study drug treatment.)" 

    • Improvement was defined as a CGI-C rating of Minimally, Much, or Very Much Improved

Patients with narcolepsy taking NUVIGIL showed improvements as measured by the ESS.
