Further study details as provided by UCB Pharma:

Primary Outcome Measures:
  • Assess efficacy of levetiracetam in the treatment of Post Herpetic Neuralgia by measuring the absolute change in the average weekly Pain Intensity Scale (PIS).

Secondary Outcome Measures:
  • Assess the efficacy, safety and tolerability of levetiracetam in the treatment of Post Herpetic Neuralgia; Reduction in the mean PIS over the last week of the evaluation period compared to the baseline period.

Estimated Enrollment: 170
Study Start Date: April 2004
Study Completion Date: September 2005
Primary Completion Date: August 2005 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All

Inclusion Criteria:

  • male or female outpatient greater than or equal to 18 years of age.
  • suffering presently from neuralgia, which has been present for at least 3 months since healing of acute herpes zoster skin rash.
  • PHN pain at entry into the study must meet the following criteria: a VAS of at least 40 mm at visit 2 (to assess pain intensity during the past week) and with an average daily score of at least 4 on the PIS during the baseline period as evaluated on a minimum of 4 days.
  • an estimated creatinine clearance of at least 50 ml/min.

Exclusion Criteria:

  • receiving professional psychological support (such as cognitive behavioral therapy) currently or within 2 weeks prior to visit 1 specifically for coping with PHN.
  • previous neurolytic or neurosurgical therapy for PHN, at any time in the subject's history or treatment with TENS (transelectroneuro stimulation) currently or within the past 2 weeks.
  • known co-existent source of pain or painful peripheral neuropathy.
  • known significant neurological disorder other than the study disease or a condition which can mimic stroke with distal neurological deficit (amyotrophy, radiculopathy, history of TIAs, multiple sclerosis, or any amputations).
  • conditions known to be associated with immunosuppressive states.
  • clinically significant major depression defined as a Beck Depression Inventory Score > 21 at selection including those with a history of Bipolar Disorder.
