Efficacy and Safety Study of NV1FGF in Patients With Severe Peripheral Artery Occlusive Disease

Phase 2

Completed

• Conditions: Peripheral Arterial Disease

• Registration Number: NCT00368797
• Lead Sponsor: Sanofi

Brief Summary

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).

• Demonstration or documentation (historical data not older than 6 months prior to first study treatment administration) of total occlusion of the affected limb of one or more of the iliac, superficial femoral, popliteal and/or one or more infrapopliteal arteries as assessed by angiography.
• Life expectancy > 6 months from the first study treatment administration.
• Poor/not candidates for revascularization (patients suitable for revascularization but with a high risk of failure/ amputation/ or patients not suitable for revascularization).
