Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase I Study of Stem Cell Mediated Angiogenesis for Limb Threatening Ischemia

Primary Outcome Measures:
  • Adverse events recorded in the 12 week study period
  • Serious Adverse events recorded for one year

Secondary Outcome Measures:
  • Changes in limb perfusion after treatment with stem cells will be assessed with arteriography, blood pressure recordings, oxygen measurements, and wound healing

Estimated Enrollment: 20
Study Start Date: December 2004
Estimated Study Completion Date: December 2007
Detailed Description:

Presently there are no effective medical therapies to enhance blood flow in the legs of patients with peripheral vascular disease. For patients with limb threatening ischemia the only option for relief of rest pain or gangrene is amputation.

There is evidence in animal and clinical studies that adult stem cells in the bone marrow, called endothelial progenitor cells, participate in the development of new blood vessels, a process called angiogenesis. In this investigation, patients with limb threatening ischemia will have their bone marrow harvested and the stem cells will then be removed and injected directly into the muscle of the diseased leg. The procedure will require about 4 hours and the subjects will be admitted to the Indiana University Medical Center overnight. The follow-up period is 12 weeks and the analysis will consist of examinations at 1, 2, 4, 6, 8, and 12 weeks. Adverse and serious adverse events will be recorded during this time period. Diagnostic studies will be obtained to measure blood flow in the treated leg during the follow up period and include transcutaneous (skin) oxygen measurements, pressure recordings in the leg, arteriography, magnetic resonance imaging, and wound healing.
