NCT00399919

Brief Summary

Patients with peripheral artery disease have decreased blood flow to exercising muscle causing pain. This decreased blood flow to the muscle affects the level of acylcarnitines which in turn decreases the level of carnitine. Carnitine allows muscles to function properly. This study will test the safety and efficacy of Propionyl-L-Carnitine taken in combination with a monitored exercise training program.

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Ambulatory outpatient who are able to exercise
  • Intermittent claudication due to peripheral artery disease

You may not qualify if:

  • Pain at rest, ischemic ulcerations, gangrene of the lower extremity
  • Peripheral Artery Disease of a non-atherosclerotic nature
  • Any disease process other than PAD, that may interfere with performance during the treadmill test or prevent the subject from reaching their claudication-limited PWT
