Daytime Sleep Latency as Measured by the Maintenance of Wakefulness Test (MWT)

The Maintenance of Wakefulness Test consisted of four 20 minute tests of the patient's ability to remain awake in soporific conditions. The Mean change from baseline to week 8 in the average MWT number of minutes until sleep onset was the primary endpoint. (NCT00066170)
Timeframe: Baseline to Week 8

The Primary Outcome Measure Was a Composite of Changes From Baseline in Three Co-primary Self Report Measures: Pain Visual Analog Scale (PVAS, Electronic Diaries), Fibromyalgia Impact Questionnaire (FIQ), and Patient Global Impression of Change (PGI-C).

"The percentage of participants who met all 3 of the following criteria:~Reduction of >=20% from baseline to week 8 in both PVAS & FIQ total score and PGI-C response of very much better or much better. Analysis was based on LOCF (Last Observation Carried Forward) data. The PVAS ranges from 0 (no pain) to 100 (worst imaginable pain). The FIQ ranges from 0 (best function) to 100 (worst function). PGI-C is a 7 point likert scale measuring change in the participant's fibromyalgia symptoms that ranges from very much worse to very much better" (NCT00087555)

Assessment of Clinical Global Impression-change.

Clinician assessment of Clinical Global Impression-Change score at week 12 of treatment intervention. The Clinical Global Impression - Change scale is a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the current time point. It is rated as: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse. One one clinician provided the ratings in this trial. (NCT00383643)

Number of Responders According to the CGI Efficacy Scale (CGI-E)

"Clinical Global Impression-Efficacy index (CGI-E) is a 4x4 rating scale that assesses the therapeutic effect (Marked, Moderate, Minimal, Unchanged or worse) of treatment medication and associated side effects (none, do not significantly interfere with patient's functioning, significantly interfere with patient's functioning, Outweigh therapeutic effect). Therapeutic effect: Marked and Side effects: None is the best. Therapeutic effect: Unchanged or worse and Side effects: outweigh therapeutic effect is the worst. Each combination of an estimated therapeutic effect and side effect is assigned a score from 1-16, 1 being the best, 16 being the worst.~Participants scoring below 4 were considered to be responders." (NCT04006925)
Timeframe: Assessed at week 12 (end of treatment period).

Epworth Sleepiness Scale (ESS) Score

Epworth Sleepiness Scale (ESS) is a scale to assess patients' general level of sleepiness. Patients choose the most appropriate number (0=would never doze, 1=slight chance of dozing, 2=moderate chance of dozing, 3=high chance of dozing) for the each situation: Sitting and reading, Watching TV, Sitting and inactive in a public place, As a passenger in a car for an hour, Lying down to rest in the afternoon, Sitting and talking to someone, Sitting quietly after a lunch, While stopped for a few minutes in the traffic in a car. 0-10: Normal range, 10-12: Borderline, 12-24: Abnormal. Participants recorded their scores for 28 days at baseline and during the 28 days leading up to week 12; scores were then averaged to calculate the score for each time point per participant, and then the median for all participants is reported. (NCT04006925)

"Patients record any episode of dream enactment, such as talking, shouting, kicking, or punching, etc. Severity is scored from 1 to 3 (1: least severe, 3 most severe):~non injurious behaviors: facial expressions, non-aggressive vocalizations (mumbling, gentle talking, casual conversation, singing, laughing...), twitches, gentle shaking, non-aggressive movements of fingers, arms or legs...;~potentially injurious: punching, kicking, arm flailing or thrashing around, at least one limb or head out of bed, sitting up in bed, crawling, attempting to stand up or leave bed, near falls, cursing, screaming, shouting, yelling, or any behavior requiring bed partner to wake up participant;~injurious: any contact with bed partner (hitting or grabbing), wall or furniture, any fall or leaving bed (doving out, walking, jumping).~The number of injurious (severe) episodes is reported."

RBD Episode Severity and Frequency During REM Sleep by Quantitative Video-PSG (Polysomnography) Analysis Per 10 Minutes of REM Sleep

The average number of dream-enactment episodes (resulting in motor behaviors, or movements) weighted for severity. Frequency and severity were calculated as the sum of RBD episodes (frequency) times severity (mild = 1; moderate = 5, severe = 10) occurring over one night's sleep, then averaged to calculate the number of episodes per 10 minutes of REM sleep. (NCT04006925)
Timeframe: Assessed at baseline and week 12 (average approximately 8 hours to assess at each time point)

Number of Responders According to the CGI Improvement Scale (CGI-I)

"Clinical Global Impression-Improvement scale (CGI-I) is a 7-point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as: 1. Very much improved, 2. Much improved, 3. Minimally improved, 4. No change, 5. Minimally worse, 6. Much worse, 7. Very much worse. 1 is the best and 7 is the worst.~Participants scoring below 4 were considered to be responders." (NCT04006925)
