Trial Outcomes & Findings for A Multicenter, Randomized, Placebo-Controlled Phase 2 Study to Evaluate the Clinical Efficacy, Safety, and Tolerability of ARX-F01 Sublingual Sufentanil in Patients Undergoing Major Abdominal Surgery (NCT NCT00718081)

NCT ID: NCT00718081

Last Updated: 2015-01-22

Results Overview

The primary outcome measure is the summed pain intensity difference over the 12-hour study period (SPID-12). A pain intensity score ranging from 0 (no pain) to 10 (worst possible pain) is obtained at baseline and throughout the 12 hour study period. The SPID-12 is calculated by summing the difference between baseline pain score and pain score at each assessment time point. The scores after summing could range from -122 to +122. A higher SPID-12 score is better.
