Efficacy and Safety of an Oral Growth Hormone Drug in the Treatment of Fibromyalgia

Completed · Phase 2 · Has a placebo group

Conditions studied: Fibromyalgia

In brief

This is a 24-week, randomized, double-blind, placebo-controlled, trial to evaluate the safety, tolerability and efficacy of an orally administered growth hormone stimulating drug, (code named MK-0677) in the treatment of female subjects with primary fibromyalgia. The basis for this study is the observation that many fibromyalgia patients are growth hormone deficient; an earlier study of injectable growth hormone had shown benefit in this population of fibromyalgia patients.
