Primary Outcome Measures
NameTimeMethod
Change From Baseline in Average Daily Pain Score (ADPS) at Each WeekBaseline to Week 14

Each participant recorded a pain score in the electronic patient diary once daily from the day after the screening visit (Visit 1) to the end of treatment/early termination visit (Visit 10). Prior to taking the study drug each morning, the participant selected the number that best described his or her pain over the past 24 hours on a scale of 0 (no pain) to 10 (worst possible pain). Higher ADPS scores indicated worse outcome. ADPS was the weekly average pain score based on the pain scores from the electronic patient diaries (Pain diary).

In this outcome, the change from baseline in ADPS is being reported with negative values representing improvements in average daily pain. The larger the negative value (ie. improvement), the greater the improvement in average daily pain.
