Inovio Pharmaceuticals, Inc. INO announced today that the use of its proprietary electroporation technology significantly enhanced the ability of a DNA therapy to stimulate blood vessel growth, which may be beneficial for the treatment of critical limb ischemia (CLI) and other forms of peripheral arterial disease (PAD). CLI's severe blockage of arteries of the lower extremities markedly reduces blood flow, resulting in notable medical impacts and death. In a mouse model, delivery of a synthetically optimized hypoxia-inducible factor-1 alpha (HIF-1α) gene using Inovio's CELLECTRA® electroporation delivery technology produced significant growth of new blood vessels and improved limb blood flow, limb function recovery, and survival from limb necrosis and amputation. The results were published in a paper entitled, "In vivo electroporation of constitutively expressed HIF-1α plasmid DNA improves neovascularization in a mouse model of limb ischemia," in the peer-reviewed Journal of Vascular Surgery.
Finding an effective therapy for PAD and CLI is imperative because the current standard of
