Trial to Assess the Efficacy and Safety of SPM 927 (200, 400, and 600mg/Day) in Subjects With Painful Distal Diabetic Neuropathy
This phase 3 trial is being conducted at approximately 80 sites in the United States (U.S.) to investigate whether lacosamide (SPM 927) at different doses reduces pain in subjects with diabetic neuropathy. Approximately 455 subjects will be randomized to placebo or to one of three doses of lacosamide. To qualify for this trial, subjects with symptoms of painful distal diabetic neuropathy ranging in duration from 6 months to 5 years must have an average pain intensity of greater than or equal to 4 on an 11-point Likert scale (0-10 scale) during the 7 day period prior to the start of treatment.
To determine what effect lacosamide has on diabetic neuropathic pain, subjects will use a diary to record their daily pain intensity (morning and evening; and pain interference with sleep (morning) and activity (evening). Use of rescue medication (acetaminophen) and subjects' quality of life will be investigated. In addition, the safety and tolerability of the different doses of lacosamide will be investigated.

|Official Title:||A Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Trial to Assess the Efficacy and Safety of SPM 927 (200, 400, and 600mg/Day) in Subjects With Painful Distal Diabetic Neuropathy|
- To investigate the efficacy of 200, 400, and 600mg/day of lacosamide compared with placebo in reducing pain in subjects with painful distal diabetic neuropathy.
- To investigate the effect of lacosamide on subjects' perception of pain, sleep, activity, and quality of life, as well as to investigate the pharmacokinetics and safety of lacosamide.
