Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Actigraphy signal collected from a wrist-worn medical-grade sensor	Result of physical activity during waking hours and participants' sleep will be evaluated to explore a relationship between participants reported outcomes and actigraphy signal collected from a wrist-worn medical-grade sensor (ActiGraph GT9X Link). Only participants who signed a separate informed consent form for wearing medical-grade sensor will be included in this evaluation.	at Week 14
Primary	Average Daily Pain Score (ADPS)	The pain scores on a scale of 0-10, where 0 = no pain and 10 = the worst possible pain. The weekly ADPS is based on participants daily pain scores.	Baseline to Week 14
Secondary	ADPS responder rate	Ratio of Participants Responding to Treatment, as Measured by Average Daily Pain Score (ADPS) Reduction from Baseline. The ADPS is used to determine categorical response rates.	at Week 14
Secondary	Pain Intensity Score Using the Short-Form McGill Pain Questionnaire (SF-MPQ): Visual Analog Scale (VAS)	The VAS, in which the participant rates pain on a 100 mm-long horizontal line, where 0 mm = no pain and 100 mm = worst possible pain.	at Week 14
Secondary	Patient Global Impression of Change	Participants rate their overall impression of how the present pain compares to baseline using a 7-point scale, where 1 = very much improved and 7 = very much worse. Patient Global Impression of Change scores are used to determine categorical responder rates.	at Week 14
Secondary	Average Daily Sleep Interference score (ADSIS)	The sleep interference scores on a scale of 0-10, where 0 = pain did not interfere with sleep to 10 = pain completely interfered with sleep. The weekly ADSIS is based on participants daily sleep interference scores.	at Week 14
Secondary	Medical Outcome Study (MOS) sleep scale	Participants rate their sleep quality during the past 4 weeks in three parts of the questionnaire: Part 1 - The participants rate the average time required to fall asleep, 0-15 minutes = 1, 16-30 minutes = 2, 31-45 minutes = 3, 46-60 minutes = 4, More than 60 minutes = 5.; Part 2 - The participants give the number of hours per night for the average hours of sleep per night.; Part 3 - The participants using a score of 1 (all of the time) to 5 (none of the time) to rate their sleep disturbance in the following areas: difficulty in falling asleep or remaining asleep, difficulty in staying awake during the day, difficulty in breathing, and snoring during sleep.	at Week 14
Secondary	Five Level EuroQol-5D (EQ-5D) version	Participants rate their Quality of Life in the following dimensions: mobility (5-point scale), self-care (5-point scale), usual activities (5-point scale), pain/discomfort (5-point scale), and anxiety/depression(5-point scale) that are combined into an overall health utilities index. Participants also rate their perception of overall health using VAS, with zero indicating worst health and 100 representing best imaginable health.	at Week 14
