Study Endpoints

Primary Endpoints

Summed Pain Intensity Difference (SPID) for MR-107A-02 versus placebo.
48 hours after randomization

SPID based on a 0 to 10-point numeric rating scale at rest (NRS-R) for MR-107A-02 versus placebo.

Overall Summed Pain Intensity Difference (SPID)
24 hours after the first dose

Participants assessed Pain Intensity (PI) using a 0-10 numeric pain rating scale (NPRS) where 0 is no pain and 10 is worst pain imaginable. PI was assessed 18 times within 24 hours after the first study dose, and immediately before any rescue medication and/or at early termination. The participant's baseline PI was subtracted from the timepoint PI, to derive a Pain Intensity Difference (PID) for each timepoint. Overall Summed Pain Intensity Difference (SPID) measures pain intensity change relative to baseline over the 24 hour period after dosing, and corresponds to the Area Under the Curve (AUC) of the PID. In this study, higher positive Overall SPID indicates better pain improvement. Overall SPID could range from -120 to 240. Two hour windowed last observation carried forward was used as applicable where PI score obtained before a rescue medication replaced PI score for each timepoint within 2 hours following rescue dose.

Secondary Endpoints

Number of doses of opioid rescue medication taken for MR-107A-02 versus placebo.
7 days after randomization
Proportion of subjects using no opioid rescue medication MR-107A-02 versus placebo.
