Brief Summary:
The purpose of this study is to evaluate whether PET/CT-RGD or MIBI can be used for the angiogenesis assessment of NL003 in PAD patients.
Detailed Description:
Hepatocyte growth factor (HGF) gene therapy has been shown to be a potential choice for CLI patients without surgical option. 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. Animal studies showed that NL003 inducing angiogenesis in the affected limb and result in an increase in tissue perfusion. Our previous phase II clinical trial has suggested the successful limb-salvaging capacity of NL003 in treatment of patients with CLTI.
In this study we will use 68Ga RGD PET/CT and 99mTc MIBI SPECT imaging methods to evaluate the effect of NL003 on angiogenesis and lower limb blood flow perfusion during the treatment of chronic lower limb ischemia, and evaluated the effectiveness and safety of the drug. The subjects will be randomly divided into the investigational drug group and the placebo group in a 1:1 ratio. NL003 or placebo will be injected into the muscle of the affected limb on D0, D14 and D28, 0.5mg/0.5mL/site, total 8mg, 32 sites. PET/CT will be measured on D14, D42 before drug administration, MIBI SPECT imaging will be collected on D60.
