Condition(s) targeted: Diabetic Neuropathy, Painful
Intervention: Pregabalin (Drug); Placebo matched with pregabalin (Drug)
Phase: Phase 3

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.
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 S 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

Minimum age: 18 Years.
Maximum age: N/A.
- 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
- 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.
- 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.
