What is being measured
The primary outcome is the main question the study is designed to answer.
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).
Measured: 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.
Measured: 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)
Measured: 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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Primary outcome
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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing oxymorphone HCl in people with Post Operative Pain, run by Endo USA Inc., a Keenova Therapeutics Company at 8 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 7 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2021.
