    Predose: Daily from 7 days before Visit 2 (start of Intervention 1) until the morning of Visit 5 (end of Intervention 2)

  • Dynamic Allodynia Area

    Screening, Days 1 & 8: 0 (pre-dose) & 4 hours post-dose,

  • Dynamic Allodynia Pain Score

    Screening, Days 1 & 8: 0 (pre-dose), 0.5, 1, 2, 3, 4, 5, and 6 hours post-dose

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • subjects who are outpatients or inpatients
  • written informed consent obtained (signed by the subject or the subject's legally acceptable representative)
  • traumatic spinal cord injury of at least 1 year duration with a nonprogressive, i.e., chronic, stage of at least 6 months duration
  • At-level neuropathic pain: spontaneous or evoked pain with neuropathic features (sharp, shooting, electric or burning pain sensation) in the region of sensory disturbance in a segmental pattern and located within two dermatomes above or below the level of spinal cord injury
  • Below-level neuropathic pain: spontaneous or evoked pain with neuropathic features (sharp, shooting, electric or burning pain sensation) in the region of sensory disturbance located at least three dermatomes below the level of spinal cord injury

You may not qualify if:

  • spinal cord injury (subjects with central pain and musculoskeletal pain must be able to make a distinction between the two)
  • subjects who have previously not responded to 300 mg/day pregabalin: a non-responder is defined as a subject who has a reduction in pain score of less than 30% from baseline
