简要总结
Patients will be switched from their current medication for painful diabetic peripheral neuropathy to evaluate the safety and efficacy of pregabalin as compared to placebo. All patients will receive pregabalin, and half of patients will receive placebo at some point during the study.

结局指标
主要结局
Change From Single-Blind Baseline in Mean Pain Score at Week 19 During Double-Blind Phase
时间窗: SB Baseline, Week 19 (DB Phase)
Mean pain score was defined as the mean of the last 7 daily diary pain ratings. Participants rated their DPN pain over the past 24 hours on an 11-point numeric rating scale ranging from 0 = no pain to 10 = worst possible pain. A rating of 1-3 was considered as mild pain; 4-6 = moderate pain; and 7-10 = severe pain. SB baseline refers to the last 7 pain diary entries up to and including Day 1.
