Overview
Brief Summary
The purpose of this study is to evaluate the effectiveness, tolerability, and safety of oxymorphone immediate release (IR) oral liquid as an analgesic for acute postoperative pain in pediatric subjects.
This post marketing study was required by the FDA. Endo Pharmaceuticals Inc. no longer promotes opioids and no longer markets Opana® ER.

- •Be hospital inpatients, expected to be hospitalized for at least 24 hours (Single-Dose Phase) and 48 hours (Multiple-Dose Phase) following the initial administration of oxymorphone immediate release
- •Available lab results, either intraoperatively (prior to surgical incision) or from within 21 days preoperatively, for clinical chemistry and hematology laboratory analytes (the results must have been reviewed by the Investigator for study eligibility)
- •Able to provide pain assessment evaluations using an age-appropriate instrument provided in the protocol
- •On an intravenous analgesic regimen utilizing a short-acting opioid analgesic following surgery AND anticipated to be switched to an oral opioid as part of the analgesic regimen (according to institution SOC)
- •Demonstrated the ability to tolerate clear fluids following surgery according to the SOC at each institution

Outcomes
Primary Outcomes
Pain Intensity Score of Oxymorphone IR Oral Liquid in Pediatric Subjects by Age Group and Time Points in Single Dose Phase
Time Frame: Baseline, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post dose; and at the time of rescue
Faces Pain Scale-Revised (FPS-R) was used for the 6 to ≤ 12 years age group, (0 = no pain and 10 = very much pain). Face, Legs, Activity, Cry, and Consolability (FLACC) behavior measurement was used for the 2 years to \< 6 years and 0 years to \< 2 years age groups, (0 = no pain and 10 = very much pain).
Descriptive Statistics of the Pain Intensity Difference (PID) by Age Group and Time Points in Single-Dose Phase
Time Frame: Baseline (prior to dose); 15, 30 minutes, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours post-dose; and at the time of rescue
Faces Pain Scale-Revised (FPS-R) was used for the 6 to ≤ 12 years age group, (0 = no pain and 10 = very much pain). Face, Legs, Activity, Cry, and Consolability (FLACC) behavior measurement was used for the 2 years to \< 6 years and 0 years to \< 2 years age groups, (0 = no pain and 10 = very much pain). PID was calculated as the pain intensity score at baseline minus the current pain intensity score at each corresponding time point.
Pain Intensity Score of Oxymorphone IR Oral Liquid in Pediatric Subjects by Age Group and Time Points in Multiple Dose Phase
Time Frame: Baseline, 0.5, 1, 1.5, 2, hours post dose, and immediately prior to all remaining doses administered through 48 hours after administration of the initial dose; and at time of rescue
Faces Pain Scale-Revised (FPS-R) was used for the 6 to ≤ 12 years age group, (0 = no pain and 10 = very much pain). Face, Legs, Activity, Cry, and Consolability (FLACC) behavior measurement was used for the 2 years to \< 6 years and 0 years to \< 2 years age groups, (0 = no pain and 10 = very much pain)
Descriptive Statistics of Pain Intensity Difference (PID) by Age Group and Time Points in Multiple-Dose Phase
Time Frame: 0.5, 1, 1.5, 2, hours post dose 1 through to Dose 12, 0 Hour; End of Study/Early Termination
Faces Pain Scale-Revised (FPS-R) was used for the 6 to ≤ 12 years age group, (0 = no pain and 10 = very much pain). Face, Legs, Activity, Cry, and Consolability (FLACC) behavior measurement was used for the 2 years to \< 6 years and 0 years to \< 2 years age groups, (0 = no pain and 10 = very much pain). PID is calculated as the pain intensity score at baseline minus the current pain intensity score at each corresponding time point.
