Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

300 mg/day pregabalin (Lyrica)

Patient take pregabalin capsule twice a day

Group Type EXPERIMENTAL

Pregabalin

Intervention Type DRUG

Subjects in the pregabalin group will start treatment with pregabalin capsule 150 mg/day for 1 week, then their dose will be increased to 300mg/day. After 1-week titration period, dose must be stable during study, no dose adjustment is permitted, and subject who cannot tolerate 300 mg/day pregabalin will be withdrawn.

At the completion of the dose maintenance phase subjects will taper off study medication over a 1-week period. 300 mg/ day subjects will taper to 150 mg/ day.

Placebo

Group Type PLACEBO_COMPARATOR

Placebo matched with pregabalin

Intervention Type DRUG

Subject will take placebo matched with pregabalin twice a day.
