  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Diagnosis of peripheral neuropathic pain syndrome, including diabetic peripheral neuropathy (DPN), postherpetic neuralgia (PHN), or post-traumatic neuropathic pain (including post-surgical), confirmed by a qualified pain specialist.
  • Subjects must have completed at least 4 daily pain diaries during the 7 days prior to Visit 2 and have an average pain score of ≥4 over the 7 days prior to Visit 2 (randomization).

Exclusion Criteria:

  • Neurologic disorders unrelated to DPN, PHN, or post-traumatic neuropathic pain (including post-surgical), that may confuse or confound the assessment of neuropathic pain.
  • Presence of any severe pain associated with conditions other than DPN, PHN, or post-traumatic neuropathic pain (including post-surgical) that may confound the assessment or self evaluation of the pain due to DPN, PHN, or post-traumatic neuropathic pain (including post-surgical).
  • Creatinine clearance < 30 mL/min (estimated from serum creatinine, body weight, age, and sex using the Cockcroft and Gault equation in Appendix E). Maximum dose for subjects with creatinine clearance of 30 to 60 mL/min is 300 mg/day
