E.5 End points |
E.5.1 | Primary end point(s) |
Safety Variables: Physical examinations will be performed during the screening period and at end of study.
Vital signs (blood pressure, pulse rate, respiratory rate, and temperature), SpO2, ECGs, reports of AEs, and somnolence using the UMSS, will be obtained at specified time intervals during the study. Clinical laboratory tests, including hepatic enzymes (alanine aminotransferase and aspartate aminotransferase), bilirubin,
creatinine, blood urea nitrogen and complete blood count with differential will be obtained before initial administration of study drug and at end of study. Safety parameters will be closely monitored throughout the study. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Safety variables will be summarized descriptively within each age group for the safety population. Safety assessments to be summarized include reports of AEs, clinical laboratory test results, vital signs
measurements, SpO2, ECGs, and assessments of somnolence (UMSS). |
|
E.5.2 | Secondary end point(s) |
Efficacy Variables: Pain intensity will be assessed by scale type dependent on whether the patient is postoperative or intubated and the patient’s age.
Pain assessments will be performed prior to each administration of IV buprenorphine and/or supplemental pain medication. The nurse will be instructed to record the pain score or have the patient self-report using 1 of the following scales: Comfort "behavior" Scale, FLACC, or FPS-R.
Pharmacokinetic Analysis:
Plasma buprenorphine concentrations, sampling times, dosing data, and individual-specific covariate effects, including age and weight, will be collected.
Compartmental PK parameters will be estimated using standard population nonlinear mixed effects methodology. Parameters of primary interest include clearance (CL/F) and apparent central volume of distribution (Vc/F). Point estimates and some measure of parameter estimation precision will be obtained for all population model parameters. The population PK analysis will be reported in a separate report from the clinical study report. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Efficacy Analysis:
Descriptive statistics (n, mean, standard error, median, minimum, and maximum) will be tabulated for pain Intensity (Comfort "behavior" Scale, FLACC, FPS-R) at specified time intervals within each age group.
