Study Summary
This study will test the safety of a drug called EW-A-401 in patients with intermittent claudication - pain and discomfort in the legs due to blockages of the arteries. The study will also evaluate whether EW-A-401 improves blood flow to the legs. EW-A-401 contains genetic material (DNA) that instructs the body to produce specific proteins that promote the growth of new blood vessels and may, therefore, improve blood flow to the legs. Patients 21 years of age and older with pain or discomfort of one or both legs due to blockages of the arteries below the groin may be eligible for this study. Candidates are screened with a medical history, physical examination, blood and urine tests, eye examination, chest x-ray and CT scan of the chest, and treadmill tests. Patients who are able to exercise more than 12 minutes on the treadmill may not enroll in the study. Participants undergo the following procedures: * Muscle biopsy: On the first day of the study, patients have a muscle biopsy. This procedure is done under local anesthesia with mild sedation. A 1-inch incision is cut into the skin over a calf muscle and a small amount of muscle tissue is removed for examination by a pathologist. * Drug treatment and tests: About 10 to 13 days after the biopsy, patients are admitted to the NIH Clinical Center for 3 to 5 days for drug treatment and tests. They receive 10 injections of either the study drug (EW-A-401) or placebo (an inactive substance) in each leg during a single session lasting about 1 hour. In addition, they have blood and urine tests, complete questionnaires about their symptoms, and undergo magnetic resonance imaging (MRI), a test that a magnetic field and radio waves to produce detailed images of body tissues and organs. For this procedure, the patient lies on a table that slides into the scanner (a large hollow tube) for imaging of the blood vessels in the legs. Patients wear headphones to muffle loud knocking and thumping sounds that occur during the scanni
