Brief Summary
Patients with postherpetic neuralgia (PHN), diabetic neuropathy (DN), complex regional pain
syndrome (CRPS), carpal tunnel syndrome, HIV neuropathy, idiopathic sensory neuropathy, or
other peripheral neuropathy participated in a Phase IV clinical trial to assess the
comparative efficacy and safety of Lidoderm monotherapy versus gabapentin monotherapy in
treating a diverse group of peripheral neuropathic pain patients.

Study Arm (s)
  • Placebo Comparator: placebo capsules + placebo patch
    Placebo to match lidocaine patch; up to four patches applied topically once daily (q24h) to the area of maximal peripheral pain AND Placebo capsules to match gabapentin for oral dosing
  • Experimental: placebo capsules + Lidoderm patch (Lidocaine Group)
    Lidoderm (lidocaine patch 5%), up to four patches applied topically once daily (q24h) to the area of maximal peripheral pain AND Placebo capsules to match gabapentin for oral dosing
  • Active Comparator: Gabapentin capsules 1800 mg/day + placebo patch

Eligibility Criteria
Inclusion Criteria:

1. Had a diagnosis of PHN, DN, CRPS, carpal tunnel syndrome, HIV neuropathy, idiopathic
sensory neuropathy, or other peripheral neuropathy (upon mutual agreement of the
sponsor and investigator)

2. Patients with PHN must have had pain >3 months after rash healing

3. Patients with DN must have had Type I or II diabetes and painful distal symmetric
sensorimotor polyneuropathy with or without dynamic allodynia of the lower
extremities

4. Patients with CRPS must have met current IASP (International Association for the
Study of Pain) diagnostic criteria

5. Patients with carpal tunnel syndrome must have had a diagnosis by combination
clinical neurological examination (e.g., Phalen's and Tinel's signs),
electrodiagnostic testing, and daily painful symptoms of at least 3 months' duration

6. Patients with HIV neuropathy must have had HIV, subjective symptoms of painful
peripheral neuropathy, and daily painful symptoms of at least 3 months' duration

7. Patients with idiopathic sensory neuropathy must have had pain of at least 3 months'
duration

8. Reached an average daily pain rating during the baseline week of pain ratings greater
than 4 on the 0-to-10 numerical pain rating scale (Question 5 of the BPI)

9. Had never received an analgesic regimen that contained lidocaine or gabapentin

Exclusion Criteria:

1. Had a neurological condition other than that associated with their pain diagnosis
which, in the opinion of the investigator, would interfere with their ability to
participate in the study

2. Were taking a lidocaine-containing product that could not be discontinued while
receiving lidocaine

3. Were taking class 1 anti-arrhythmic drugs (e.g., mexiletine, tocainide)
