  • Change From Baseline in Average Pain Interference With Sleep (11-point Likert Scale) [ Time Frame: Baseline to end of entire treatment phase visit ]
    Change from Baseline in average pain interference with sleep (11-point Likert scale) where 0=no interference with sleep and 10=worst possible interference with sleep.
  • Change From Baseline in Average Pain Interference With Activity (11-point Likert Scale) [ Time Frame: Baseline to end of entire treatment phase visit ]
    Change from Baseline in average pain interference with activity (11-point Likert scale) where 0=no interfence with activity and 10=worst possible interference with activity.
  • Change From Baseline in Quality of Life Using the SF-36 Health Survey - Physical Component Summary (PCS) [ Time Frame: Baseline to Termination Visit ]
    Change from Baseline in quality of life using the SF-36 Health Survey - Physical Component Summary (PCS). Values range from 0 to 100 with high values indicating a good condition. Positive change in baseline values indicate improvement in quality of life.
  • Change From Baseline in Quality of Life Using the SF-36 Health Survey - Mental Component Summary (MCS) [ Time Frame: Baseline to Termination Visit ]
    Change from Baseline in quality of life using the SF-36 Health Survey - Mental Component Summary (MCS). Values range from 0 to 100 with high values indicating a good condition. Positive change in baseline values indicate improvement in quality of life.

Brief Title  ICMJE A Follow-On Trial to Assess the Long Term Safety and Efficacy of SPM 927 in Painful Distal Diabetic Neuropathy
Official Title  ICMJE A Multi-Center, Open-Label, Follow-On Trial to Assess the Long Term Safety and Efficacy of SPM 927 in Subjects With Painful Distal Diabetic Neuropathy
Brief Summary Phase 2/3 open-label trial to assess the safety and tolerability of long-term treatment with lacosamide (SPM 927) in subjects with painful diabetic neuropathy. The safety and tolerability of the different doses of lacosamide will be investigated.
Detailed Description This phase 2/3 open-label trial is being conducted at approximately 100 sites in the US to assess the safety and tolerability of long-term treatment with lacosamide (SPM 927) in subjects with painful diabetic neuropathy. Approximately 525 subjects will be enrolled. To qualify for this trial, subjects with symptoms of painful distal diabetic neuropathy ranging in duration from 6 months to 5 years must have completed trials SP665, SP742, or SP768 and, in the investigator's opinion, may benefit from long-term administration of lacosamide. Subjects will be titrated to their optimal dose of lacosamide (up to 600mg/day). The safety and tolerability of the different doses of lacosamide will be investigated throughout the trial. In addition, to determine what effect lacosamide has on diabetic neuropathic pain, subjects will use a diary to record their daily pain intensity and pain interference with sleep and activity. Subjects' quality of life will also be investigated.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Subjects who completed Study SP665, SP742, or SP768 and, in the investigators opinion, might benefit from long-term administration of SPM 927. Exception: subjects who prematurely discontinued Study SP742 or SP768 due to lack of efficacy or due to intolerability to trial medication may be eligible to participate in Study SP745, after consultation with the medical monitor.

Exclusion Criteria:

  • Subject has clinically relevant electrocardiogram (ECG) abnormalities, or QT-corrected (QTc) interval >=500 milliseconds (ms), and/or a QTc interval increase of >=60ms from the mean pre-dose QTc value at Visit 2 of Studies SP665, SP742 or SP768.
  • Subject has aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) >=3 times the upper limit of the normal range (ULN) with total bilirubin >=2 times ULN or transaminases (AST and/or ALT) >=5 times ULN.
  • Subject has a clinically relevant medical condition that, in the opinion of the investigator, jeopardizes or compromises the subject's ability to participate in this trial.
