Abstract

PURPOSE: We sought to investigate the safety and efficacy of intramuscular gene therapy with vascular endothelial growth factor (VEGF) in patients with chronic critical leg ischemia. METHODS: Gene transfer was performed in 24 limbs of 21 patients with rest pain, some of whom also had nonhealing ischemic ulcers (n = 16) due to occlusive peripheral arterial disease. Between 400 μg and 2000 μg of phVEGF165 (400 μg, n = 2; 800 μg, n = 4; 1200 μg, n = 4; 1600 μg, n = 6; and 2000 μg, n = 8) was injected directly into the muscles of the ischemic limb; the same dose was injected 4 weeks later. The ratio of blood pressures at the ankle and brachial artery was measured before and after treatment. RESULTS: Mean (± SD) plasma levels of VEGF increased significantly from 26 ± 31 pg/mL to 63 ± 56 pg/mL (P 165 for patients with chronic critical leg ischemia is safe, feasible, and effective.
