  • Within-Subject Change In Average Daily Pain Score During the Treatment Period. [ Time Frame: From Baseline Visit to Final Week of Treatment (approximately 9 years) ] [ Designated as safety issue: No ]
    The Average Daily Pain Score is calculated using an 11-point Likert scale, ranging from 0 (no pain) to 10 (worst pain ever experienced).
  • Within-Subject Change In The Perception Of Each Of The Individual Cardinal Symptoms of Pain During The Treatment Period - Shooting. [ Time Frame: From Baseline Visit to Final Week of Treatment (approximately 9 years) ] [ Designated as safety issue: No ]
    Each individual cardinal symptom of pain is calculated using an 11-point Likert scale, ranging from 0 (no pain) to 10 (worst possible pain).
  • Within-Subject Change In The Perception Of Each Of The Individual Cardinal Symptoms of Pain During The Treatment Period - Burning. [ Time Frame: From Baseline Visit to Final Week of Treatment (approximately 9 years) ] [ Designated as safety issue: No ]
    Each individual cardinal symptom of pain is calculated using an 11-point Likert scale, ranging from 0 (no pain) to 10 (worst possible pain).
  • Within-Subject Change In The Perception Of Each Of The Individual Cardinal Symptoms of Pain During The Treatment Period - Paraesthesiae. [ Time Frame: From Baseline Visit to Final Week of Treatment (approximately 9 years) ] [ Designated as safety issue: No ]
    Each individual cardinal symptom of pain is calculated using an 11-point Likert scale, ranging from 0 (no pain) to 10 (worst possible pain).
  • Within-Subject Change In The Perception Of Each Of The Individual Cardinal Symptoms of Pain During The Treatment Period - Numbness. [ Time Frame: From Baseline Visit to Final Week of Treatment (approximately 9 years) ] [ Designated as safety issue: No ]
    Each individual cardinal symptom of pain is calculated using an 11-point Likert scale, ranging from 0 (no pain) to 10 (worst possible pain).
  • Within-Subject Change In The Perception Of Each Of The Individual Cardinal Symptoms of Pain During The Treatment Period - Allodynia. [ Time Frame: From Baseline Visit to Final Week of Treatment (approximately 9 years) ] [ Designated as safety issue: No ]

    Each individual cardinal symptom of pain is calculated using an 11-point Likert scale, ranging from 0 (no pain) to 10 (worst possible pain).

    Allodynia is defined as neuropathic pain caused by normally innocuous stimuli becoming painful.

  • Subject's Global Impression of Change In Pain During The Treatment Period. [ Time Frame: From Baseline Visit to Final Week of Treatment (approximately 9 years) ] [ Designated as safety issue: No ]

    The Subject's Global Impression of Change is a self-evaluation by the subject of their overall change in relief of neuropathic pain since the beginning of the study rated on a 7-point scale ranging from:

    1. Much better
    2. Moderately better
    3. Mildly better
    4. No change
    5. Mildly worse
    6. Moderately worse
    7. Much worse
  • Investigator's Global Impression of Change In Pain During The Treatment Period. [ Time Frame: From Baseline Visit to Final Week of Treatment (approximately 9 years) ] [ Designated as safety issue: No ]

    The Investigator's Global Impression of Change is a physician's assessment of the patient's overall change in relief of neuropathic pain since the beginning of the study rated on a 7-point scale ranging from:

    1. Much better
    2. Moderately better
    3. Mildly better
    4. No change
    5. Mildly worse
    6. Moderately worse
    7. Much worse
  • Percentage of Days With Concomitant Pain ("Rescue") Medications Taken During Baseline Phase. [ Time Frame: Baseline Period (approximately 1 week) ] [ Designated as safety issue: No ]

    The percentage of days where rescue medication was taken is summarized by visit and by Treatment Phase (Baseline, Titration, and Titration + Treatment).

    The percentage of days of rescue medication use is defined as the number of days observed within the visit/study phase with rescue medication divided by the number of days in the visit/study phase times 100 for subjects who had taken the rescue medication.

    Summary statistics include mean and standard deviation.

  • Percentage of Days With Concomitant Pain ("Rescue") Medications Taken During Titration Phase. [ Time Frame: Titration Period (approximately 6 weeks) ] [ Designated as safety issue: No ]

    The percentage of days where rescue medication was taken is summarized by visit and by Treatment Phase (Baseline, Titration, and Titration + Treatment).

    The percentage of days of rescue medication use is defined as the number of days observed within the visit/study phase with rescue medication divided by the number of days in the visit/study phase times 100 for subjects who had taken the rescue medication.

    Summary statistics include mean and standard deviation.

  • Percentage of Days With Concomitant Pain ("Rescue") Medications Taken During Titration and Treatment Phases. [ Time Frame: From Titration Phase through Treatment Phase (approximately 9 years) ] [ Designated as safety issue: No ]

    The percentage of days where rescue medication was taken is summarized by visit and by Treatment Phase (Baseline, Titration, and Titration + Treatment).

    The percentage of days of rescue medication use is defined as the number of days observed within the visit/study phase with rescue medication divided by the number of days in the visit/study phase times 100 for subjects who had taken the rescue medication.

    Summary statistics include mean and standard deviation.

An Open-label Continuation Trial to Assess the Continued Efficacy and Safety of Ascending Doses of Lacosamide in Subjects With Chronic Refractory Neuropathic Pain

This trial is the follow-on trial to a preceeding open-label trial which included patients with chronic refractory neuropathic pain. It is conducted at one site in the United Kingdom and the patient enrollment is completed. The patients had successfully completed the above mentioned trial and, in the investigator's opinion, would benefit from long-term administration of Lacosamide. After a 1-week run-in phase the patients were uptitrated to their optimal dose and then continued into the maintenance phase. Different pain qualities are assessed by a patient's diary.
