Anatomically Directed Lower Extremity Gene Therapy for Ulcer Healing: A Double-Blind, Randomized, Placebo-Controlled Study (LEGenD-1)

Circ Cardiovasc IntervPublished Randomised controlled trial

Authors' conclusion

Anatomically targeted intramuscular delivery of AMG0001 significantly accelerated healing in patients with moderate chronic limb-threatening ischemia and neuroischemic ulcers and may represent a promising nonsurgical therapeutic strategy.

Primary result

As reported in the abstract

Values

Healed by 6 months AMG0001 (pooled) 63.3% · Placebo 38.5% · P = 0.053

  • AMG0001 (pooled) vs Placebo: P = 0.007 — median time to healing
  • AMG0001 4 mg vs Placebo: P = 0.017 — median time to healing
  • AMG0001 8 mg vs Placebo: P = 0.022 — median time to healing
