  • Have clinical evidence of diabetic peripheral neuropathy in the lower extremities for 1 to 5 years before study entry
  • Experienced lower extremity pain due to diabetic peripheral neuropathy on nearly a daily basis for the previous 3 months
  • Have hemoglobin A1c levels less than or equal to 10%
  • Have a stable diabetic treatment regimen, including oral medications for controlling diabetes, insulin, or diet for 3 months before screening

You may not qualify if:

  • History of a poor response to 3 or more medications for diabetic peripheral neuropathy (DPN), with poor response is defined as treatment with medications in the following categories of therapy for at least 1 month at therapeutic dosages without at least moderate improvement, as judged by the study doctor: antiepileptic drugs, tricyclic antidepressants, serotonin norepinephrine reuptake inhibitors (SNRIs), opioid analgesics, or lidocaine patch

  • Prior neurolytic treatment (destruction of nerves by the application of chemicals, heat, or cold), intrathecal pumps, or spinal cord stimulators for DPN pain
  • Use of herbal creams or ointments for pain relief within 48 hours, capsaicin within 6 months, or systemic corticosteroids within 3 months before the baseline period
  • Prior exposure to RWJ-333369 (carisbamate).
