This study is to test the effectiveness of pregabalin in treating nerve pain caused by diabetes. The suitable subjects will be patients who also use an non-steroid anti-inflammatory drug for another pain which is not related to the diabetic nerve pain.

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Endpoint mean pain score, based on the mean of the last 7 daily pain numeric rating scale (NRS) scores from the daily pain diaries while receiving study medication in each treatment period [ Time Frame: 6 week ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportions of 30% and 50% pain responders using NRS scores from the daily pain diary (Pain Diary) [ Time Frame: 6 week ] [ Designated as safety issue: No ]
  • Patient Global Impression of Change assessed at the end of Period 1 (PGIC) [ Time Frame: 6 week ] [ Designated as safety issue: No ]
  • Daily Sleep Interference Rating Scale (Sleep Diary) [ Time Frame: 6 week ] [ Designated as safety issue: No ]
  • Quality of life using Norfolk Quality of Life Questionnaire - Diabetic Neuropathy (QoL DN) [ Time Frame: 6 week ] [ Designated as safety issue: No ]
  • European Quality of Life in 5 Dimensions (EQ 5D) [ Time Frame: 6 week ] [ Designated as safety issue: No ]
  • Pain severity and impact using the Brief Pain Inventory - short form (BPI sf) [ Time Frame: 6 week ] [ Designated as safety issue: No ]
  • Anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) [ Time Frame: 6 week ] [ Designated as safety issue: No ]
