Details and patient eligibility

About

This study is a double-blind study to evaluate the efficacy and safety of NV1FGF, a pCOR plasmid constructed by inserting the gene coding for the FGF compared to placebo in patients with severe Peripheral Arterial Occlusive Disease, Fontaine's stage IV. The efficacy was assessed by the complete healing of at least one ulcer in the treated limb, 25 week post-baseline and secondary by the rate of amputation and death.

Inclusion criteria

Outpatients with severe Peripheral Artery Occlusive Disease defined as Rutherford's Grade III, category 5 or 6, or Fontaine's stage IV.
Trophic lesions with no signs of healing (no reduction in ulcer size or depth) for at least 2 weeks prior to first study treatment administration (Day 1).
Patients with objective evidence of peripheral vascular disease (resting ankle pressure < 70 mmHg and/or toe pressure < 50 mmHg, and/or resting ankle-brachial index (ABI) < 0.4 and/or resting toe-brachial index (TBI) < 0.3 and/or metatarsal pulse volume recording (PVR) flat or barely pulsatile) in the diseased limb on two consecutive examinations performed at least 1 week apart.
