Change from Baseline to Week 8 in Mean Sleep Latency from the Maintenance of Wakefulness Test (MWT)
Query!
Assessment method [1]
0
0
The MWT evaluates a person's ability to remain awake under soporific conditions for a defined period of time. Because there is no biological measure of wakefulness, wakefulness is measured indirectly by the inability or delayed tendency to fall asleep. This tendency to fall asleep is measured via electroencephalography-derived sleep latency in the MWT. The MWT consists of four 40-minute sessions done 2 hours apart. Sleep latency in each session will be recorded. Participants will be required to stay awake in between the 4 sessions.

Change from Baseline to Week 8 in Epworth Sleepiness Scale (ESS) Total Score
Query!
Assessment method [1]
0
0
The ESS provides individuals with 8 different situations of daily life and asks them how likely they are to fall asleep in those situations (scored 0 to 3) and to try to imagine their likelihood of dozing even if they have not actually been in the identical situation; the scores are summed to give an overall score of 0 to 24. Higher scores indicate stronger subjective daytime sleepiness, and scores below 10 are considered to be within the normal range.

An adverse event (AE) is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product. A TEAE is defined as any event emerging or manifesting at or after the initiation of treatment with a study intervention or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the study intervention or medicinal product.

Summary
Brief summary
The main aim of this study is to see how TAK-861 works on symptoms of narcolepsy, including excessive daytime sleepiness and cataplexy. Approximately 100 participants will take part in the study across North America, Europe and Asia Pacific. The treatment (TAK-861 or placebo) will be administered for 8 or 12 weeks. After this treatment period the participant will have the option to participate in a separate, long- term extension study during which all participants will be treated with TAK-861.
