Outcomes
Primary Outcome Measures
Duration Adjusted Average Change (DAAC) of Mean Pain Score
DAAC was derived from participant's daily pain diary, where pain was measured on an 11-point Numerical Rating Scale (NRS-Pain)ranging from 0 (did not interfere with sleep) to 10 (completely interfered [unable to sleep due to pain]). The DAAC was calculated as the mean of all daily pain diary rating post baseline minus the baseline score then multiplied by the proportion of the planned study duration completed by the participant.
Secondary Outcome Measures
Change From Baseline in Weekly Mean Pain Score
Mean weekly score was calculated as the average of the available daily diary pain score values for the week. Pain score was measured on an 11-point numeric rating scale (NRS): 0 (no pain) to 10 (worst possible pain).
Number of Participants With >=30% Reduction in Weekly Mean Pain Score From Baseline
Mean weekly score was calculated as the average of the available daily diary pain score values for the week. Pain score was measured on an 11-point numeric rating scale (NRS): 0 (no pain) to 10 (worst possible pain).
Number of Participants With Categorical Scores on the Patient Global Impression of Change (PGIC) (Full Scale)
The PGIC is a participant-rated instrument measuring change in the participant's overall status on a 7-point scale: 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, 7=very much worse.

Title
Change From Baseline in Medical Outcomes Study Sleep Scale (MOS-SS)- 9-Item Overall Sleep Problems Index
Description
Participant rated questionnaire to assess sleep quality and quantity. Consists of a 9-item overall sleep problems index (length of time to fall asleep, how many hours of sleep each night during past 4 weeks); 7 subscales rated 1 (all the time) to 6 (none of the time): sleep disturbance, snoring, awaken short of breath (SOB) or with a headache, somnolence adequacy, and sleep quantity. Scores are transformed (actual raw score minus lowest possible score divided by possible raw score range multiplied by 100); total score range = 0 to 100; higher score indicates greater intensity of attribute.
