|Official Title:||Effects of Levetiracetam on Chronic Neuropathic Pain Following Spinal Cord Injury: a Randomized, Double-blind, Placebo-controlled, Cross-over, Multi-center Study|
- Change in median pain intensity (measured daily on a 10 point NRS) of spontaneous pain from baseline week to last week of treatment. [ Time Frame: Last week of each 5-week treatment period ] [ Designated as safety issue: No ]
- Spasms and spasticity; pain relief for total, at- and below-level pain; evoked pain; escape medication; NPSI; predictive value of the presence of evoked pain; Global impression of change; sleep disturbance. [ Time Frame: Last day of each 5-week treatment period ] [ Designated as safety issue: No ]

Study design: Randomized double-blind cross-over study of levetiracetam (Keppra) against corresponding placebo with a 1 week baseline period followed by 2 x 5 weeks treatment periods separated by a 1 week wash-out period.
Methodology: Levetiracetam and corresponding placebo is gradually increased during two weeks from 500 mg x 2 daily to 1500 mg x 2 daily (1000 mg x 2 daily is allowed if 1500 mg x 2 is not tolerated), and kept on that dose for three weeks.
The study will be monitored by the GCP units of Aarhus and Copenhagen University.
