Summary

Pregabalin has proven effective in previous clinical trails in other countries in relieving neuropathic pain associated with postherpetic neuralgia and painful diabetic neuropathy.

This study is being conducted according to China registration requirement to submit a reapplication with new local diabetic peripheral neuropathy study as a commitment plus the existing data to apply for Lyrica "pain associated with postherpetic neuralgia" indication after Lyrica "pain associated with postherpetic neuralgia" is approved.

Clinical Details

Official title: An 11-week Randomized, Double-blind, Multi Center, Placebo-Controlled Study To Evaluate The Efficacy, Safety And Tolerability Of Pregabalin (300 Mg/Day) Using A Fixed Dosing Schedule In The Treatment Of Subjects With Pain Associated With Diabetic Peripheral Neuropathy.

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: Endpoint mean pain score based on the pain scores from the subject's daily pain rating scale

Secondary outcome:

Weekly mean pain scores from the subject's daily pain rating scale

Weekly mean sleep interference scores from the subject's daily sleep interference scale

Responder rates with at least a 30% reduction from baseline in weekly mean pain score

Change from baseline in Short-Form McGill Pain Questionnaire at week 9

Change from baseline in Pain Visual Analogue Scale at week 9

Change from baseline in Medical Outcomes Study -Sleep Scale at week 9

The Subject Global Impression of Change at week 9

The Clinical Global Impression of Change at week 9

Change from baseline in Hospital Anxiety and Depression Scale at week 9

- At the baseline and randomization visits, a score of ≥50 mm on the Visual Analogue

Scale, at randomization, subjects must have completed at least 5 daily pain interference diaries, and have an average daily pain score of ≥5 over the past 7 days.
