  • •3.Clinical diagnosis of one or the other of the following neuropathic pain conditions:
  • •Postherpetic neuralgia (PHN) present for a minimum of 6 months after onset of rash.
  • •Post-traumatic peripheral neuralgia [Mechanical injury (including surgical injury) to peripheral nerves/root e.g. stabbing or burning pain that persists to a varying degree within the affected or adjacent area of trauma or corresponding dermatome for 6 months or more after the precipitating insult].
  • •4.Subjects with history of cancer (except basal cell carcinoma) should be in complete remission (defined by NCI as follows: all signs and symptoms of cancer have disappeared, although cancer still may be in the body) for at least 12 months prior to baseline and throughout the baseline period.
  • •5.Subject has pain defined as:
  • •A mean daily-average-pain score of at least 4 and no greater than 9 on the 11 point Likert Scale during the last 7 days of the baseline period.
  • •Subject must complete their pain diaries for at least 6 of the last 7 days of the baseline period.
  • •PHN or post-traumatic peripheral neuralgia is the subject’s predominant pain condition and he/she is able to distinguish between the neuropathic pain and other concurrent painful conditions.

  • •7.Subject is eligible for enrollment as determined by the investigator from medical history, physical examination findings, 12-lead electrocardiograph (ECG) findings, and clinical laboratory test results. Laboratory results outside of the reference range must be documented as acceptable by the investigator. In addition, the liver function tests, thyroid function tests and creatinine clearance (calculated) must be within the specific ranges below:
  • •ALT and AST < 1.5 times the upper reference range
  • •Creatinine Clearance (calculated) > 70 mL/min
  • •FT3 and FT4 > lower reference range or < 1.1 times the upper reference range
  • •TSH within normal reference range
  • •Are the trial subjects under 18? no
  • •Number of subjects for this age range:
  • •F.1.2 Adults (18-64 years) yes

  • •3.Post-traumatic peripheral neuralgia with evidence of an ongoing insult to the nerve (e.g. nerve compression as a result of a herniated disc).
  • •4.Any significant disease or other significant abnormal findings at the screening and or baseline evaluation, as determined by the investigator.
  • •5.History of treatment for, or evidence of, alcohol or drug abuse within the past year or regular alcohol consumption exceeding an average of 3 units of alcohol per day (Attachment 13.3).
