Abstract
Intramuscular injection of donaperminogene seltoplasmid (recombinant human hepatocyte growth factor plasmids) represents a gene therapy that treat patients with chronic limb-threatening ischemia (CLTI). The HOPE CLTI-2 trial was a Phase 3, multicenter, double-blind, placebo-controlled study aimed to evaluate the efficacy and safety of seltoplasmid in patients with Rutherford class 5 CLTI. This study did not require participants to be ineligible for revascularization, allowing enrollment of patients with CLTI caused by either atherosclerosis (ASO) or Buerger's disease (TAO). The primary endpoint was the complete ulcer healing rate at 6 months. A total of 242 participants (53.3% ASO versus 46.7% TAO) were enrolled, with 161 receiving seltoplasmid and 81 receiving placebo. Complete ulcer healing was achieved in 70 patients in the seltoplasmid group compared to 15 patients in the placebo group, resulting in an adjusted healing rate difference of 26.1% (95% confidence interval [CI]: 15.1-37.0%; P < 0.001). The hazard ratio for healing was 2.31 (95% CI: 1.32-4.05; P = 0.004). The benefits of seltoplasmid on ulcer healing persisted in both TAO and ASO subgroups. Serious adverse events were rare. Our study demonstrated that seltoplasmid significantly improved ulcer healing rates in patients with Rutherford class 5 CLTI compared to placebo.
