E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy of two dose levels of pregabalin compared to placebo as an adjunctive treatment in reducing the frequency of partial onset seizures in pediatric subjects 1 month through <4 years of age. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of pregabalin compared to placebo on the frequency of partial onset seizures as determined by responder rate in pediatric subjects 1 month through <4 years of age.
To assess the safety and tolerability of pregabalin in pediatric subjects 1 month (44 weeks gestational age) through <4 years of age with partial onset seizures. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Subject must have 3 partial onset seizures in the month prior to screening.
- Subject must have 2 partial onset seizures during the 48 hour baseline phase.
- Signed Informed Consent
- On 1-3 stable anti-eplieptic drugs at screening |
|
E.4 | Principal exclusion criteria |
- Primary generalized seizures including clonic, tonic, clonic-tonic, absence, febrile seizures, and infantile spasms
- Lennox-Gasteau, BECTS, and Dravet's syndrome
- Status epliepticus within 1 year of screening
- Any change in AED regimen with 7 days of screening
- Progressive structural central nervous system (CNS) lesion or a progressive encepholopathy
- Progressive errors of metabolism |
|
E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint will be the log transformed double blind 24 hr seizure rate for all partial onset seizures collected at Visit 6 (48 hour Video-EEG assessment phase) during the double blind phase as determined by the central reader. This 24-hour seizure rate will be calculated as follows for the double-blind period:
Double Blind 24 - hr EEG seizure rate = # of seizures in double blind 48 - hr assessment phase \ # of hours of Video - EEG monitoring x 24
When the log-transformation is used, the quantity 1/28 is added to the double blind 24-hr EEG seizure rate for all subjects to account for any possible "0" seizure incidence. This will result in the following primary efficacy measure: log e (double blind 24-hr EEG seizure rate +1/28). Results will be reported as “percent change in seizures” relative to placebo.
A minimum of 24 hours of evaluable Video-EEG will be required to utilize the EEG. In cases where there is less than 24 hours of evaluable Video-EEG, the seizure rate will be set to missing.
The baseline 24-hr EEG seizure rate will be calculated in the same respective manner. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Responder Rate, defined as subjects who have a ≥50% reduction from baseline in partial seizure rate during the double-blind 48 hour Video-EEG phase. Subjects meeting this criterion will be considered responders.
The evaluation of safety will include adverse event (AE) data (occurrence, nature, intensity, and relationship to study drug), assessment of clinical laboratory data and the results of physical examinations, vital signs, weight, neurological examinations, and electrocardiograms (ECGs). |
