Use Art-assist and Neupogen to Treat Chronic Limb Ischemia
Withdrawn before enrolling · Phase 4
Conditions studied: Lower Limb Ischemia
In brief
The purpose of this study is to measure the concentration of cells and proteins in the patient's blood during administration of Nuopogen (Filgrastim), a medication that is FDA approved for stem cell mobilization, in combination with a programmed pneumatic compression device (PPCD) (Art-Assist Device). The Art-Assist Device is an FDA approved device that promotes blood flow in the patient's legs. A patient will be prescribed this device and this drug to help improve the poor circulation in his/her leg. The use of Nuopogen along with the Art-Assist Device has not been approved by the FDA and is considered experimental. This study is not designed to find out how well the Art-Assist Device works, nor how well the drug works in mobilizing stem cells. Instead, it is a study of how well cells lining blood vessels in calf respond to increases in shear stress, and how well the increase in the population of certain cells in the blood stream effect how the new blood vessels will form. It is important for clinical reasons, and for the purposes of this study, that the patient uses the Art-Assist Device as prescribed on a daily basis as discussed with the patient's doctor
