The FINANCIAL -- TOKYO & NEW YORK -- Pfizer Japan announced today the top-line
results for Lyrica (pregabalin) Study A0081208 – Randomized,
Double-Blind, Multicenter, Placebo-Controlled Study to Evaluate Efficacy
and Safety of Pregabalin (CI-1008) in the Treatment of Fibromyalgia.
The results demonstrated a statistically significant reduction in the endpoint mean pain score, the primary efficacy analysis in the study, with pregabalin compared to placebo. Further analyses will be conducted on these initial results.
The essential features of fibromyalgia are chronic widespread musculoskeletal pain and tenderness. The pathophysiology of fibromyalgia is complex and not well understood, but fibromyalgia is a disabling disorder that adversely affects quality of life in these afflicted patients.
“We are pleased with the top-line results of this study and look forward to more fully understanding the potential benefits that Lyrica may bring to fibromyalgia patients in Japan,” said Akihisa Harada, M.D., vice president, Head of Development Japan, at Pfizer Japan.
Study A0081208 was a 16-week, randomized, double-blind, placebo-controlled, parallel group, multi-center study comparing pregabalin flexibly dosed (300-450mg/day, dosed twice-daily) and placebo in subjects with fibromyalgia. A total of 501 subjects were enrolled in the study (251 pregabalin and 250 placebo) in 45 investigative sites in Japan. The preliminary results of the study indicate that the most common adverse events in the study were somnolence, dizziness, weight increased, constipation, feeling abnormal, edema peripheral and blurred vision.
