Trial Outcomes & Findings for Phase 3 Study of Efficacy and Safety of the XaraColl® Bupivacaine Implant After Hernioplasty (NCT NCT02523599)

NCT ID: NCT02523599

Last Updated: 2021-01-08

Results Overview

Sum of Pain Intensity (SPI24). The time weighted sum of pain intensity from 0 to 24 hours (ie, the area under the NRS PI curve from 0 to 24 hours). Where 0 indicated "no pain" and 10 indicated "worst pain possible". This type of measurement scale is called "NRS" or Numerical Rating Scale For the purpose of (SPI) computation, PI at Time 0 (Baseline PI) is set to zero for all patients who have test article implantation. SPI will not be calculated for randomized but not treated patients. A lower score is a better outcome. Minimum value would be "0" and Maximum value would be 240. Time-weighted SPI is calculated as the sum of the pain intensities between successive time points (i.e., if SPI24 = ∑\[PI x (time t - time t-1)\], where "t" represents a given time point,"t-1" represents the previous time point, and time is expressed in hours). This represents the AUC (Area Under the Curve) of the pain intensities when calculated with the trapezoidal rule.

SECONDARY outcome

Timeframe: Time 0 through 24 hours

Population: (mITT Population)

Total use of opioid analgesia (TOpA) from Time 0 through 24 hours (TOpA24). This is a basic measurement of counting in total the number of morphine tablets (15 mg) patients had use within a 24 hour period (typically called "rescue" to help manage pain. Zero (0) is the "lowest" score. The lower the number of tablets the better outcome.

Sum of pain intensity (SPI).The time weighted sum of pain intensity from 0 to 48 hours (ie, the area under the NRS PI curve from 0 to 48 hours).
