NCT02408991

Brief Summary

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

Outcome Measures

Primary Outcomes (1)

  • Measuring the pharmacologic increase in of CD31+ (mature endothelial cell)

    Using the FACSaria sorter. Following clot formation (30 min) each tube will be centrifuged for 15 min at 1000g and the separated serum will be stored at -20° C. Protein will be measured using Enzyme-linked immunosorbent assays (ELISA).

    4 months

Secondary Outcomes (3)

  • Measureing the pharmacologic increase in CD34+(progenitor cell),

    4 months

  • Measureing the pharmacologic increase in VEGFR2+ (endothelial progenitor cell)

    4 months

  • Pharmacologix measurement of nitrite

    4 months

Study Arms (1)

Drug: NeupogenDevice: Art-Assist Device

Interventions

Neupogen is given as an injection in your skin every three days for a total of 5 doses.

Also known as: Filgrastim
AA and Neopogen

The programmed pneumatic compression device (PPCD) is to be worn for a minimum of three hours daily while patient is sitting down
