NCT00437281

Brief Summary

The purpose of the study is to evaluate the safety, tolerability, and pharmacokinetics of multiple doses of pregabalin in pediatric patients with partial onset seizures that are incompletely controlled on their current medications.

Outcome Measures

Primary Outcomes (2)

  • Number of Treatment-Emergent Adverse Events (AEs) by Severity: Double-blind Treatment

    Analysis for severity of AEs was performed separately for double-blind and open-label treatment. AE = any untoward medical occurrence in participant who received study drug without regard to possibility of causal relationship. AEs were classified as mild, moderate and severe based on severity assessment: Mild = no interference with participant's usual function; Moderate = some interference with participant's usual function; Severe = significant interference with participant's usual function. Treatment-emergent events for double-blind treatment included events between baseline and Day 7 that were absent before treatment or that worsened relative to pretreatment state. Participants may experience more than 1 AE.

    Baseline to Day 7

  • Number of Treatment-Emergent Adverse Events (AEs) by Severity: Open-label Treatment

    Analysis for severity of AEs was performed separately for double-blind and open-label treatment. AE = any untoward medical occurrence in participant who received study drug without regard to possibility of causal relationship. AEs were classified as mild, moderate and severe based on severity assessment: Mild = no interference with participant's usual function; Moderate = some interference with participant's usual function; Severe = significant interference with participant's usual function. Treatment-emergent events for open-label treatment included events between Day 8 and 28 days after the open-label dose that were absent before treatment or that worsened relative to pretreatment state. Participants may experience more than 1 AE.

    Day 8 up to 28 days after open-label dose of study medication

Secondary Outcomes (14)

  • Number of Participants With Clinically Significant Change in Physical and Neurological Findings

    Baseline up to 7 days post-last dose of study medication

  • 28-Day Seizure Frequency Rate

    Baseline up to 7 days post-last dose of study medication

  • Area Under the Curve From Time Zero to End of Dosing Interval (AUCtau): Multiple-Dose Analysis

    Pre-dose, 0.5, 1, 2, 4, 8, 12 hours post-dose on Day 8

  • Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - ∞)]: Single-Dose Analysis

    Pre-dose, 0.5, 1, 2, 4, 8, 12, 24 hours post-dose on Day 8

  • Maximum Observed Plasma Concentration (Cmax): Multiple-Dose Analysis

    Pre-dose, 0.5, 1, 2, 4, 8, 12, 24 hours post-dose on Day 8

  • +9 more secondary outcomes

Limitations and Caveats

Results are reported for AUCtau for multiple-dose PK analysis and AUC (0-∞) for single-dose PK analysis, instead of AUC (0-24), as per change in planned analysis.
