Title:

Modafinil In the Treatment of Fatigue in Post-Polio Syndrome

Number:

03-N-0276

Summary:

This study, conducted at the Walter Reed Army Medical Center, the National Rehabilitation Hospital, and the National Institutes of Health, will examine whether the drug Modafinil can decrease fatigue in patients with post-polio syndrome. Many people who have had polio develop weakness and severe fatigue several years after their recovery from the acute disease. Modafinil is approved by the Food and Drug Administration to improve wakefulness in patients with narcolepsy (disease in which patients have excessive daytime sleepiness) and has been used to treat patients with fatigue related to other medical conditions, such as multiple sclerosis. This study will compare the effects of two doses of Modafinil and of a placebo (a pill with no active ingredient) on fatigue in patients with post-polio syndrome.

Patients who develop fatigue, weakness, muscle pain or atrophy, and functional loss at least 15 years after recovering from polio and whose symptoms cannot be attributed to another cause may be eligible for this study. Candidates will be screened with a medical history, physical and neurological examinations, fatigue rating scales, electrocardiogram, blood and urine tests, drowsiness and depression evaluations, and an electroymogram (EMG) to diagnose nerve or muscle problems. For the EMG, electrodes (small metal discs) are taped to the skin and a needle is inserted into a muscle to record the electrical activity.

Candidates will also undergo a sleep study to exclude abnormal sleep patterns as the cause of the fatigue. For this study, patients stay overnight at the NIH hospital. Electrodes are placed on the throat, on a finger, and on the chest (for an electrocardiogram), and a respiratory belt is placed around the chest-abdomen area. During sleep (from 10:30 p.m. to 6 a.m.), brain waves, eye and leg movements, muscle tone, respiration, and heart rate are recorded. Beginning at 8 a.m. the following morning, the patient takes 20-minute naps to measure the level of daytime sleepiness, using a recording technique similar to that of the all-night study. When five naps are completed, the sleep study ends. Candidates may also undergo a lumbar puncture (spinal tap) to check for certain chemicals in the spinal fluid that might be related to fatigue and to look for possible causes of post-polio syndrome. This procedure is optional. For the lumbar puncture, a local anesthetic is given and a needle is inserted in the space between the bones in the lower back where the cerebrospinal fluid circulates below the spinal cord. A small amount of fluid is collected through the needle.

Patients enrolled in the study will complete a sleep diary during the entire study period. They will be randomly assigned to one of two treatment groups-Modafinil or placebo-for 6 weeks, followed by a 2-week washout period with no medication, and then a crossover phase, in which patients who took Modafinil for the first 6 weeks now take placebo, and those who took placebo now take Modafinil.

At the first study visit, patients will be given a supply of study medication and have blood drawn. They will take one pill twice a day during both study phases. In both study phases, evaluations will be done 3 and 6 weeks after starting the medication. The evaluations include filling out the same forms completed at the screening visit, a review of drug side effects, and a review of medical problems since the last study visit. At the 6-week visit, blood is also drawn.
