Peripheral Vascular Disease Clinical Trial
Official title:
A Phase III, Double-Blind, Randomized, Placebo-Controlled, Multicenter Study to Assess the Safety and Efficacy of NL003 in Subject With Critical Limb Ischemia(Rutherford 4)
To evaluate the safety and efficacy of recombinant human hepatocyte growth factor (HGF) bare plasmid injection for local intramuscular injection in the treatment of patients with severe lower limb hemorrhagic disease (Rutherford grade 4)
Management of CLI process consumes a significant amount of healthcare resources,and the new therapeutic approaches are required. Hepatocyte growth factor (HGF) has been shown to be a potent angiogenic growth factor stimulating the growth of endothelial cells and migration of vascular smooth muscle cells. Because of its pluripotent capabilities, increasing the availability of HGF in ischemic tissues to achieve therapeutic angiogenesis has been a growing area of research. This study will use NL003, which is a DNA plasmid that contains novel genomic cDNA hybrid human HGF coding sequence (HGF-X7) expressing two isoforms of HGF, HGF 728 and HGF 723. As there are currently no approved drugs that can reverse CLI and as most patients have exhausted surgical and endovascular intervention options, inducing angiogenesis in the affected limb with NL003 may result in an increase in tissue perfusion, which, in turn improve wound healing, reduce pain and improve limb salvage rates. ;
