Condition(s) targeted: Fibromyalgia
Intervention: Pregabalin (Drug)
Phase: Phase 4

The purpose of the study is to evaluate whether pregabalin is effective in treating subjects
who have had fibromyalgia for less than one year. Pregabalin has been approved by the FDA
for treatment of fibromyalgia. the purpose of the study is to see if subjects identified
through their primary care physicians who have fibromyalgia and have had symptoms for less
than one year respond to pregabalin and to identify characteristics of that response.
Official title: Fibromyalgia of Less Than One Year Duration in Primary Care: Treatment Response in a Double Blind, Placebo Controlled Study of Pregabalin
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: Change in pain VAS from study entry to end of study
Change in total score FIQ from study entry to last visit.
Change in total score FM 2010 Clinical Scale from study entry to last visit.
Change in PGIC from study entry to last visit.
Change in total score for HRQOL from study entry to last visit.
The randomized clinical trial of pregabalin in early-onset fibromyalgia.
At the baseline visit, each subject will be asked if they wish to consider enrolling in Part
II. If they agree, the details of the study will be explained and Dr Goldenberg will consent
those who wish to enroll in Part II. The first 75 patients who consent will be enrolled in
the study, the randomized clinical trial of pregabalin in early-onset fibromyalgia.
After a study subject has been enrolled, they will be randomized to one of two treatment
groups. All subjects will be randomized, 1: 1 either to the pregabalin group (group A) or
the placebo group (group B). Randomization will take place after enrollment via selection
of one of a multitude of envelopes containing a random number. Each random number will have
been preassigned to either Group A or group B.
Minimum age: 18 Years.
Maximum age: N/A.
