Information source: Pfizer
ClinicalTrials.gov processed this data on August 23, 2015 Link to the current ClinicalTrials.gov record.
Condition(s) targeted: Diabetic Neuropathy, Painful
Intervention: Pregabalin (Drug); Placebo matched with pregabalin (Drug)
Phase: Phase 3
Status: Completed
Sponsored by: Pfizer Official(s) and/or principal investigator(s): Pfizer CT.gov Call Center, Study Director, Affiliation: Pfizer
Summary
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.
Clinical Details

as compared to screening; and during the 1 week screening period, with more than one
pain score <3 in pain scores.
