An Open-Label, Non-randomized, Multicenter, Ascending Dose by Age, Single- and Multiple-Dose Evaluation of the Effectiveness, Safety, and Tolerability of Oral Liquid Oxymorphone HCl Immediate-Release Oral Liquid for Acute Postoperative Pain in Pediatric Subjects

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.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain Intensity Score of Oxymorphone IR Oral Liquid in Pediatric Subjects by Age Group and Time Points in Single Dose Phase	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).	Baseline, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post dose; and at the time of rescue
Descriptive Statistics of the Pain Intensity Difference (PID) by Age Group and Time Points in Single-Dose Phase	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.	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
Pain Intensity Score of Oxymorphone IR Oral Liquid in Pediatric Subjects by Age Group and Time Points in Multiple Dose Phase	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)	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
Descriptive Statistics of Pain Intensity Difference (PID) by Age Group and Time Points in Multiple-Dose Phase	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.	0.5, 1, 1.5, 2, hours post dose 1 through to Dose 12, 0 Hour; End of Study/Early Termination
