  • Number of Participants Experiencing the Occurrence of at Least One Treatment-emergent Adverse Event (TEAE) During the Evaluation Period From Entry Visit 1 Through End of Treatment (Approximately 6.5 Years). [ Time Frame: From entry Visit 1 through end of treatment (approximately 6.5 years) ] [ Designated as safety issue: No ]
    Adverse events are any untoward medical occurrences in a subject administered study treatment, whether or not these events are related to treatment.
  • Number of Participants Experiencing the Occurrence of at Least One Serious Adverse Event (SAE) During the Evaluation Period From Entry Visit 1 Through End of Treatment (Approximately 6.5 Years). [ Time Frame: From entry Visit 1 through end of treatment (approximately 6.5 years) ] [ Designated as safety issue: No ]

    A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose:

    • Is fatal
    • Is life-threatening
    • Results in persistent or significant disability/incapacity
    • Requires inpatient hospitalization
    • Prolongs existing inpatient hospitalization
    • Is a congenital anomaly/birth defect
    • Is considered to be an important medical event. Such an event may not be immediately life threatening or result in death or hospitalization but may jeopardize the subject or may require intervention to prevent one of the other outcomes listed in the definitions above
To assess the tolerability and safety of long-term lacosamide administration in subjects with painful distal diabetic neuropathy. Assessment of adverse events, changes in laboratory parameters, ECGs, and physical examinations. [ Time Frame: Assessments are made at all clinic visits. ]

The secondary objective is to evaluate the efficacy of long-term use of lacosamide in this indication. Efficacy will be determined by pain score ratings assessed in a patient's diary and with ratings at the clinic visits. [ Time Frame: Efficacy will be determined by pain score ratings assessed in a patient's diary for daily entries and with ratings at the clinic visits. ]
