Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To test the hypothesis that Propionyl-L-Carnitine taken in combination with monitored exercise training may improve exercise performance the study will randomize male or female adults with peripheral artery disease and claudication to receive either Proprionyl-L-Carnitine or Placebo.
