Study of the Insomnia in Patients With Low Back Pain

Status Completed

Clinical Trial Summary

The purpose of this study is to examine whether insomnia due to chronic low back pain can improve with use of eszopiclone.

Clinical Trial Description

There is a great need to develop effective treatments for insomnia in patients with chronic low-back pain. Chronic low-back pain is among the most prevalent of all health complaints, is associated with enormous health-care and productivity costs, reduced quality of life, and limitation of function and is almost universally associated with insomnia (Rives and Douglas, 2004). While it had long been believed that insomnia was a symptom of pain conditions and of little consequence in its' own right, a growing literature suggests that insomnia has important effects on the clinical course of pain syndromes (Smith and Haythornthwaite, 2004). While pain may disrupt sleep, it appears that problems with sleep increase pain and are associated with impairments in daytime function. The emerging point of view is that specific treatment for both pain and insomnia is needed for optimal clinical management (Smith and Haythornthwaite, 2004). Surprisingly, despite the fact that chronic low-back pain is the most common pain condition, the treatment of insomnia in this disease has never been studied. As a result, we propose to carry out the first double-blind placebo-controlled study of the treatment insomnia in patients with chronic low back pain.

Comparison(s): We will test the hypothesis that treating the insomnia with eszopiclone 3 mg (ESZ) along with management of pain with naproxen 500 mg bid (NAP) will result in statistically significantly improved sleep compared with placebo. We also propose to test as a secondary hypothesis that treatment with ESZ will lead to significant improvement in pain and daytime function vs. placebo. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
