Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria

  • Subject is between the ages of 18 to 75 years with a diagnosis of diabetes mellitus and must have a diagnosis of painful distal symmetric diabetic polyneuropathy and presence of ongoing pain due to diabetic peripheral neuropathy for at least 6 months.
  • Subject must have an average score of greater than or equal to 4 on the 24 hour average pain score (0-10 numerical rating scale) collected over approximately 7 days prior to the Baseline Visit.

Exclusion Criteria

  • Subject has clinically symptomatic neuropathic pain conditions that can not be distinguished from diabetic neuropathic pain or interfere with the pain assessments of diabetic neuropathic pain.
  • A subject has newly diagnosed or clinically significant medical conditions or mental disorders that would preclude participation or would interfere with diabetic neuropathic pain assessments or other functions.
  • Subject has clinically significant abnormalities in clinical laboratory tests.
