Drug: Gabapentin extended-release tablets
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Factorial Assignment
Primary Purpose: Treatment
|Official Title:||A Phase 3 Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of the Safety and Efficacy of Gabapentin Extended Release (G-ER) Tablets in the Treatment of Patients With Postherpetic Neuralgia|
- The primary study objective is to assess the relative efficacy of G-ER versus placebo in reducing the average daily pain score from the baseline week to the final week of the efficacy treatment period (Treatment Week 10) in patients with PHN
- Daily pain scores will be measured using an electronic diary.
- Secondary objectives include assessment of changes from baseline in average daily sleep interference scores.
|Study Start Date:||May 2006|
|Study Completion Date:||July 2007|
The primary study objective is to assess the relative efficacy of G-ER dosed once daily (1800 mg following the evening meal) or twice daily (600 mg AM/1200 mg PM), versus placebo in reducing the mean daily pain score from the baseline week to the end of the efficacy treatment period (Treatment Week 10) in patients with PHN.
Secondary efficacy measures will include changes from baseline in mean weekly sleep interference scores, Short-Form McGill Pain Questionnaire (SF-MPQ), the Neuropathic Pain Scale (NPS), Brief Pain Inventory (BPI), Patient Global Impression of Change (PGIC), and Investigator-Rated Clinical Global Impression of Change (CGIC).
