NCT00350103

Brief Summary

The purpose of this trial is to assess whether 400mg/day of lacosamide is effective in reducing pain caused by distal diabetic neuropathy. Two dose-escalation schemes for lacosamide will be used to further determine the efficacy of the "standard" scheme and to evaluate the efficacy and safety of a more rapid titration scheme. Subjects will be randomly assigned to one of three treatment groups. Subjects in two of the groups will receive lacosamide at a dose of 400mg/day, but different dose-escalation schemes will be used to reach this final dose. The third group of subjects will receive a placebo. Subjects will have a 2 in 3 (66 %) chance of getting lacosamide. The maximum lacosamide dose in this trial will be 400mg/day. The maximum treatment duration will be 18 weeks, including a two-week Pre-Treatment Phase and a 12 weeks period on a stable dose of lacosamide or placebo.

Outcome Measures

Primary Outcomes (1)

  • Change in Average Daily Pain Score From Baseline Week to the Last 4 Weeks of the Maintenance Phase

    An 11-point Likert scale is used to assess the subject's average daily pain. This scale is completed by the subject twice daily (once in the morning and once in the evening). The subject rates his/her average pain over the last 12 hours, from 0 (no pain) to 10 (worst pain ever experienced). The daily pain score is defined as the average score of those collected in the morning and evening. The value reported below is calculated as a difference between the average of the last available 28 days of maintenance for participants completing the maintenance phase (or the last 28 days prior to discontinuation for participants who discontinued in the titration or maintenance phase) and the average of the Baseline week.

    Last 4 weeks of Maintenance Phase, compared to the Baseline Week

Secondary Outcomes (37)

  • Time to Sustainable Pain Relief

Study Arms (3)

Lacosamide Standard Titration (ST)

EXPERIMENTAL

Subjects had their dose titrated from 100 mg/day to 400 mg/day at weekly intervals of 100 mg. Subjects in this treatment group reach their target dose of 400 mg/day 3 weeks after Visit 2. All subjects completing the Titration Phase enter a 12-week Maintenance Phase.

Drug: SPM 929

Lacosamide Fast Titration (FT)

EXPERIMENTAL

Subjects receive 200 mg/day LCM for the first 3 days, 300 mg/day for the next 4 days, and reach their target dose of 400 mg/day after 1 week. They undergo sham titration for the remaining 3 weeks of the Titration Phase. All subjects completing the Titration Phase enter a 12-week Maintenance Phase.

Drug: SPM 929

Placebo

PLACEBO COMPARATOR

Subjects underwent sham titration for the entire Titration Phase. All subjects completing the Titration Phase enter a 12-week Maintenance Phase

Drug: Placebo
