Study Endpoints

Primary Endpoints

Daily Pain Numeric Rating Scale (NRS)
Baseline, Week 1, Week 2, Week 3 and Week 4

The endpoint average pain score, based on the mean of the last 7 days' daily pain numeric rating scale (NRS) scores at (NRS is an 11-point scale where 0 = no pain and 10 = worst possible pain) from the daily pain diaries while receiving study medication during the treatment period.

Average Pain Intensity Numerical Rating Scale (PI-NRS) Score - From 0 to 4 Hours Post-dose
Every 15 minutes from 0 to 4 hours post-dose

Participants rated severity of their pain at 11 point PI-NRS, by choosing a number between 0 and 10, where 0= no pain and 10= worst possible pain; higher scores signify more pain. The average pain score was calculated as the mean of the pain scores recorded every 15 minutes from 0 to 4 hours post-dose.

Total Pain Relief From 0 to 6 Hours (TOTPAR[6])
0 to 6 hours

TOTPAR(6) was defined as the total area under pain relief (PR) curve through first 6 hours after dosing, calculated using trapezoidal rule. PR was assumed to be 0 at 0 hour. PR assessed on a 5-point categorical scale: 0(none), 1 (a little), 2 (some), 3 (a lot) and 4 (complete), at different time points during study up to 6 hours. Total score range for TOTPAR(6): 0 (worst) to 24 (best), higher value indicated greater degree of PR. Posterior mean, standard deviation were estimated based on analysis of covariance (ANCOVA) model with non-informative priors within outlier robust Bayesian framework.
