Study Summary

The purpose of this study is to evaluate three different dosage strengths of sublingual ARX-F01 (Sufentanil NanoTab) versus a sublingual Placebo NanoTab for the treatment of post-operative pain in subjects following total knee replacement surgery. We hypothesize that subjects receiving placebo will have poor pain relief and will drop out of the study sooner and more often than the ARX-F01-treated subjects.

Primary Outcome

SPID-12 is the sum of the pain intensity difference (PID) over the 12 hour time period. A pain intensity score of 0 (no pain) to 10 (worst possible pain) is obtained before starting the study and throughout the 12 hour time period. The pain score at each assessment time point is subtracted from the baseline pain score (starting point) to provide the total sum score or SPID-12. A higher SPID-12 score is better and indicates a reduction in pain intensity compared to the baseline score. Per protoco
