A Phase 3b Multicenter Study of Pregabalin in Fibromyalgia Subjects Who Have Comorbid Depression

The intent of this study is to identify and treat fibromyalgia subjects with comorbid depression who are receiving an SSRI (selective serotonin reuptake inhibitor) or SNRI (selective norepinephrine reuptake inhibitor) primarily for their depression and to determine whether pregabalin demonstrates improvement relative to placebo in improving pain associated with fibromyalgia.
