Treadmill Exercise and GM-CSF Study to Improving Functioning in Peripheral Artery Disease (PAD)

Summary

The PROPEL study will test the hypothesis that GM-CSF combined with supervised treadmill exercise will significantly improve functional performance in patients with PAD more than GM-CSF alone or supervised treadmill exercise alone. In addition to identifying novel therapeutic options for patients with PAD, the current proposal is expected to identify mechanisms by which functional impairment is improved in patients with PAD.
