Brief Summary

Lower extremity arteriosclerosis obliterans is due to the formation of atherosclerotic plaque in the lower extremities, resulting in the stenosis and occlusion of the artery, leading to chronic ischemia of the limbs. Although bypass surgery and angioplasty ( or interventional therapy ) are effective methods for vascular treatment in patients with PAD to revascularize, a significant proportion of patients with the arterial disease are not eligible for direct arterial surgery. Meanwhile, there are many patients who suffer from diffuse arterial disease or severe peripheral disease not suitable for interventional therapy. Stimulation of arteriogenesis( blood bypassing the occluded arteries through a large number of collateral vessels ) and angiogenesis ( generating new small blood vessels ) have become the focus of research. Our recombinant SeV-hFGF2/dF injection (R\&D code BF30 ) uses the human basic fibroblast growth factor ( FGF2 ) gene to express the target protein FGF2 locally by intramuscular injection. The preparation can efficiently express FGF2 in infected cells and secrete it to the periphery and be fixed in the intercellular substance. Since FGF2 is in the upstream regulatory pathway of VEGF, HGF and other factors, it can regulate the coordinated expression of these cytokines related to the growth and function of new blood vessels, and finally, produce mature blood vessels. To evaluate the safety ( tolerance), pharmacokinetics (PK), biological activity, and immunogenicity of BF30 in patients with lower extremity arterial occlusive disease, and to explore clinical benefits. MAIN OBJECTIVE: To evaluate the safety ( tolerability ) of single-dose BF30 in patients with lower extremity arterial occlusive disease, and to provide evidence for the dose of subsequent clinical trials. Secondary objective: To explore the pharmacokinetics (PK), biological activity, the immunogenicity of BF30, and to initially explore clinical benefits.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female, aged 18-80 years old, weighing \> 50kg, with an expected survival of more than 1 year;
  • diagnosed as Lower extremity arterial occlusive disease (ASO , DAO , TAO) , and Rutherford grade 2 to 5 (moderate intermittent claudication - mild tissue defect), if both of the subject's limbs have lower extremity arterial ischemic disease, the limb that could not be revascularized or more severe one to study by the investigator;
  • Patients are not eligible for revascularization (eg, interventional endovascular treatment or surgery); or patients who have failed previous revascularization treatment;
  • For patients who are taking cilostazol, prostaglandins or sarpogrelate for the treatment of lower limb ischemia, a stable dose should be used for at least 1 month before the test drug is injected ;
  • Before enrollment, confirmed by DSA or CTA as the superficial femoral artery ( ie, the femoral artery below the branch of the deep femoral artery), one or more stenosis of the radial artery and its lower artery ≥ 75% or occlusion;
  • The intended to treat lower extremity ABI ≤ 0.9 ;
  • Volunteer to participate in the trial and sign the informed consent form.

You may not qualify if:

  • Patients with malignant tumors or clinically significant history of a hematological disease, or clinically significant results of tumor screening tests;
  • Patients with a history of alcohol or drug abuse in the last 12 months;
  • The affected limb may need an amputation in 4 weeks;
  • Acute lower extremity arterial ischemic disease or acute progressive disease of lower extremity arterial ischemic disease;
  • The index limb has serious infections ( such as cellulitis, osteomyelitis, etc.), distal fascia or bone exposure;
  • Cardiac function is classified as grade III or IV heart failure according to the New York Heart Association (NYHA) ;
  • Patients with cerebral infarction, cerebral hemorrhage, myocardial infarction, and unstable angina in the past 3 months;
  • Type I diabetes patients;
  • Poorly controlled hypertension up to three antihypertensive drugs combined, defined as those at screening or baseline testing: systolic blood pressure \> 160 mmHg or diastolic blood pressure \> 110 mmHg ;
  • Patients with grade 3 and above proliferative retinopathy history;
  • Currently receiving immunosuppressive agents or radiotherapy and chemotherapy;
  • Antiviral drugs, drugs for inhibiting u-PA activity, such as diuretics, amiloride, and suramin, were used within 2 weeks before administration ;
  • Subjects included: HIV, hepatitis B, hepatitis C, routine hematology laboratory tests found that patients with significant clinical significance ( hepatitis B virus carriers can be selected); or blood routine, blood biochemistry, liver function, etc. Any of the following abnormalities (if the investigator judges that the abnormality may be caused by the inspection operation, still exists after one retest):
