简要总结
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.

入选标准
- •Male and female subjects aged 18 years or older
- •Diagnosis of painful, distal, symmetrical, sensorimotor polyneuropathy which is due to diabetes mellitus (Type 1 or 2), and symptoms of painful diabetic neuropathy for 6 months to 5 years (inclusive).
- •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.
- •Patient who are willing and capable to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
- •Women of childbearing potential are willing to use contraception during study.
排除标准
- •Subjects with more than 30% decrease on the Pain Visual Analog Scale at randomization as compared to screening; and during the 1 week screening period, with more than one pain score <3 in pain scores.
- •Subject has other kinds of neurological disorder, pain of other reason, or skin condition that could confuse the assessment.
- •Subject with any other serious or unstable condition which in the opinion of the investigator might compromise participation in the study.

结局指标
主要结局
Baseline Mean Pain Score
时间窗: Baseline
The daily pain rating scale (DPRS) consists of an 11-point numeric scale ranging from 0 (no pain) to 10 (worst possible pain). Participants described their pain during the past 24 hours by choosing the appropriate number between 0 and 10.
Change From Baseline in Mean Pain Score at Endpoint
时间窗: Baseline and end of fixed dose phase (Day 63/Week 9)/Early Termination (Study Endpoint)
The daily pain rating scale (DPRS) consists of an 11-point numeric scale ranging from 0 (no pain) to 10 (worst possible pain). Participants described their pain during the past 24 hours by choosing the appropriate number between 0 and 10. The mean endpoint pain score was obtained from the last 7 available DPRS scores of the daily pain diary while the participant was on study medication, up to and including the day after the last Week 8 (Day 57) dose.
