Scientific title | Efficacy and tolerability of levetiracetam in central post-stroke pain - a randomised, double blind, placebo controlled, cross-over study |
Study acronym | LESS |
Study objectives | Levetiracetam has a positive pain relief effect in patients with central post stroke pain and is well tolerated. |
Ethics approval(s) | Not provided at time of registration |
Health condition(s) or problem(s) studied | Central poststroke pain (CPSP) |
Intervention | The study is based on a cross over design. Each randomised patient will receive 8 weeks of Levetiracetam and 8 weeks of placebo in blinded order. The medication periods consist of a 4 week titration phase starting with 1000 mg/day (14 days) to 2000 mg/day (14 days) and followed by 4 weeks of a constant dose of 3000 mg/day. Pain diary based on NRS, lab test, cerebral magnetic resonance imaging (MRI), neurological examination including extended sensibility and sensory testing, questionnaires, drug administration. |
Intervention type | Drug |
Pharmaceutical study type(s) | |
Phase | Not Specified |
Drug / device / biological / vaccine name(s) | Levetiracetam |
Primary outcome measure | Primary endpoint is a reduction of two points in the median pain intensity on a scale 0 (no pain) to ten (maximum pain) assessed by the patient during the last week of treatment with 3000 mg levetiracetam or placebo compared to the median pain intensity assessed in the second pre-treatment baseline week. |
Secondary outcome measures | Secondary endpoints are the median pain scale during the last week of treatment with 1000 mg and 2000 mg levetiracetam or placebo. Further secondary endpoints are the results of the clinical sensory and pain assessment and the results of the NRS (Numeric Rating Scale), Beck Depression Inventary, the SF36 (Short Form-36 Health Survey (Quality of Life) as well as the PSQI (Pittsburgh Sleep Quality Index). |
