ListOutcomeTime frameDescription
PrimaryChange From Baseline in Average Numerical Rating Scale (NRS) Score at Week 12Baseline and Week 12
Participants were asked to assess the average pain intensity on an 11-point NRS ranging from 0 (no pain) to 10 (maximum pain imaginable) by selecting a number on the scale applicable to their pain. Baseline pain score is defined as the average pain intensity score over the last 3 days prior to the randomization. Change from Baseline in NRS score is the mean NRS score at Week 12 minus mean NRS score at Baseline.
SecondaryChange From Baseline in Average Numerical Rating Scale (NRS) Score at Week 1 to 11Baseline, Week 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11
Participants were asked to assess the average pain intensity on an 11-point NRS ranging from 0 (no pain) to 10 (maximum pain imaginable) by selecting a number on the scale applicable to their pain. Baseline pain score is defined as the average pain intensity score over the last 3 days prior to the randomization. Change from Baseline in NRS score is the mean NRS score at corresponding week minus mean NRS score at Baseline.
SecondaryPercentage of Participants With Treatment Response Based on Numerical Rating Scale (NRS)Week 12
Percentage of participants with treatment response in mean NRS score by greater than equal to 30 or 50 percent (%) in the last week from baseline were considered as responders. Participants were asked to assess the average pain intensity on an 11-point NRS ranging from 0 (no pain) to 10 (maximum pain imaginable) by selecting a number applicable to their pain on the scale.
SecondaryNumber of Participants With Categorical Scores on Patient's Global Impression of Change (PGIC) ScaleWeek 8 and Week 12
The PGIC is a 7-point scale that requires the participants to assess how much their illness has improved or worsened relative to a Baseline state at the beginning of the intervention. The response options are 1 = very much improved, 2 = much improved, 3 = minimally improve, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse.
SecondaryNumber of Participants With Categorical Scores on Physician's Global Assessment ScaleWeek 8 and Week 12Physician's Global Assessment Scale assesses the therapeutic efficacy (effectiveness) of the study drug for pain control on a 2-point scale of "effective" and "ineffective".
SecondaryChange From Baseline in Pain Interference Subscale Score Based on Brief Pain Inventory (Short Form) (BPI-sf) ScaleBaseline and Week 12
The BPI-sf consists of 15 Items (Item 1:presence of pain; Item 2:pain location; Items 3 to 6:pain severity; Item 7:status of pain treatment; Item 8:efficacy of pain treatment; and Items 9a to 9g: interference of pain with daily life). Pain interference sub-scale score ranges from 0 (do not interfere) to 10 (completely interferes). Higher scores indicates worsening. Total score is defined as the mean scores from Items 3, 4, 5, 6 and 9 recorded on an 11-point scale where 0 = no pain and 10 = pain as bad as you can imagine. Lower score indicates an improvement in pain.
SecondaryChange From Baseline in Pain Subscale Score Based on Brief Pain Inventory (Short Form) (BPI-sf) ScaleBaseline and Week 12
The BPI-sf consists of 15 Items (Item 1:presence of pain; Item 2:pain location; Items 3 to 6:pain severity; Item 7:status of pain treatment; Item 8:efficacy of pain treatment; and Items 9a to 9g: interference of pain with daily life). Pain Sub-scale score ranges from 0 (absent \[no pain\]) to 10 (extreme \[pain as bad as you can image\]). Higher scores indicates worsening. Total score is defined as the mean scores from Items 3, 4, 5, 6 and 9 recorded on an 11-point scale where 0 = no pain and 10 = pain as bad as you can imagine. Lower score indicates an improvement in pain.
SecondaryChange From Baseline in Brief Pain Inventory (Short Form) (BPI-sf) Total Score at Week 12Baseline and Week 12
The BPI-sf consists of 15 Items (Item 1:presence of pain; Item 2:pain location; Items 3 to 6:pain severity; Item 7:status of pain treatment; Item 8:efficacy of pain treatment; and Items 9a to 9g: interference of pain with daily life). Total score is defined as the mean scores from Items 3, 4, 5, 6 and 9 recorded on an 11-point scale where 0 = no pain and 10 = pain as bad as you can imagine. Lower score indicates an improvement in pain.
SecondaryChange From Baseline in Sleep Latency Based on Sleep Questionnaire at Week 12Baseline and Week 12Sleep Latency was related to "How long after bedtime or lights out did the participant fall asleep last night ". Decrease in time indicates an improvement.
SecondaryChange From Baseline in Time Slept Based on Sleep Questionnaire at Week 12Baseline and Week 12Time slept was related to "How long did the participant sleep last night". The mean change for the time in hours slept during the last night was reported.
