A Safety, Efficacy, and Tolerability Trial of Pregabalin as Add-On Treatment in Pediatric Subjects <4 Years of Age With Partial Onset Seizures.
January 15, 2021 updated by: Pfizer's Upjohn has merged with Mylan to form Viatris Inc.
A Double-blind, Placebo-controlled, Parallel-group, Multicenter Study Of The Efficacy And Safety Of Pregabalin As Adjunctive Therapy In Children 1 Month Through <4 Years Of Age With Partial Onset Seizures
This study is designed to evaluate the effectiveness of 2 doses of pregabalin to reduce seizure frequency as an add on therapy in pediatric subjects 1 month to <4 years of age with refractory partial onset seizures.
It is hypothesized that both doses of pregabalin will demonstrate superior efficacy when compared to placebo by reducing the partial onset seizure frequency and that pregabalin will be safe and well tolerated.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Log Transformed 24-Hour Seizure Rate for All Partial Onset Seizures During the Double-Blind Treatment Phase
Time Frame: Day 1 up to Day 14
|
All partial onset seizures experienced during treatment phase were recorded by central reader during the 48 to 72 hour video-electroencephalogram (EEG).
Double Blind 24 hour EEG seizure rate for all partial onset seizures = ([Number of seizures in double blind 48 to 72 hour EEG assessment] divided by [number of hours of video-EEG monitoring])*24.
The EEG assessment was done at the end of the fixed dose treatment.
For log-transformation, the quantity 1 was added to the double blind 24 hour EEG seizure rate for all participants to account for any possible "0" seizure incidence.
This resulted in final calculation as: log transformed (double-blind 24-hour EEG seizure rate + 1).
|
Day 1 up to Day 14
|

---|---|---|
Responder Rate: Percentage of Participants With at Least 50 Percent (%) or Greater Reduction From Baseline in 24-Hour Seizure Rate for All Partial Onset Seizures During the Double-Blind Treatment Phase
Time Frame: Day 1 up to Day 14
|
Responder Rate was defined as percentage of participants who had a 50% or greater reduction from baseline in 24-hour seizure rate during the double-blind treatment phase.
Double Blind 24 hour EEG seizure rate for all partial onset seizures = ([Number of seizures in double blind 48 to 72 hour EEG assessment] divided by [number of hours of video-EEG monitoring])*24.

Measure Description |
Time Frame |
---|---|---|

Time Frame: Day 1 up to End of study (EOS) (maximum Day 25)
|
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Treatment-emergent AEs were events which occurred between first dose of study drug and up to end of study (up to Day 25) that were absent before treatment or that worsened relative to pre-treatment state.
AEs included both serious and non-serious adverse events.
|
Day 1 up to End of study (EOS) (maximum Day 25)
|
Number of Participants With Treatment-Related Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: Day 1 up to EOS (maximum Day 25)
|
Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug.
An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Treatment-emergent AEs were events which occurred between first dose of study drug and up to end of study (up to Day 25) that were absent before treatment or that worsened relative to pre-treatment state.
Relatedness to drug was assessed by the investigator.
AEs included both serious and non-serious adverse events.
|
Day 1 up to EOS (maximum Day 25)
|
Number of Adverse Events by Severity
Time Frame: Day 1 up to EOS (maximum Day 25)
|
An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug.
AEs were classified according to the severity in 3 categories a) mild: AEs does not interfere with participant's usual function b) moderate: AEs interferes to some extent with participant's usual function c) severe: AEs interferes significantly with participant's usual function.

|
Neurological examinations included: coordination; cranial nerve function (CNF); gait and station; level of consciousness (LOC); lower and upper extremity sensation; muscle strength; muscle tone; nystagmus; reflexes and speech.
Abnormalities in neurological examination were based on investigator's discretion and also, some components of the neurological examination were not done for certain participants due to participant age or significant developmental impairment.
Only those categories of neurological examination in which at least 10% of participants had an abnormality in any treatment group at any time point were reported in this outcome measure.
|

|
