Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open-Label Multicenter Extension Study To Determine Long Term Safety And Efficacy Of Pregabalin (Lyrica) As Monotherapy In Patients With Partial Seizures

Primary Outcome Measures:
  • Seizure Frequency [ Time Frame: Baseline up to Week 28 ] [ Designated as safety issue: No ]
  • Number of Participants With (All Causality) Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Baseline up to Week 28 ] [ Designated as safety issue: Yes ]
    Counts of participants who had treatment-emergent adverse events (TEAEs), defined as newly occurring or worsening after first dose. Participants with multiple occurrences of an AE within a category were counted once within the category.

  • Number of Participants With Laboratory Test Values of Potential Clinical Importance [ Time Frame: Baseline up to Week 28 ] [ Designated as safety issue: Yes ]
    Pre-defined criteria were established for each laboratory test (hematology, blood chemistry and urinalysis) to define the values that would be identified as of potential clinical importance.
