Background: A randomized, prospective, multicenter, double-blind, placebo-controlled, phase II clinical trial was performed to determine whether inhibition of leukocyte adherence by administration of monoclonal antibody directed against intercellular adhesion molecule-1 would improve burn wound healing. Methods: One hundred ten patients with burn injury ranging from 10% to 30% total body surface area were enrolled. Fifty-six patients received placebo (saline) and 54 patients received murine monoclonal antibody to the human intercellular adhesion molecule-1 (enlimomab). Treatment was initiated within 6 hours of injury. Patients had three distinct partial-thickness woundsites assessed. LaserDoppler flowmetry was used to stratify wounds on the day of injury. Wounds were assessed for healing status on day 21 postburn and categorized as healed, nonhealed, or grafted. Results: Patients treated with enlimomab had asignificantly increased percentage of wounds thathealed spontaneously in less than 21 days overall and when stratified by burn wound laser Doppler blood flow readings for those wounds at greatest risk for nonhealing.Conclusion These Results support the concept that leukocyte adherence is involved in the pathogenesis of burn wound necrosis and suggest a therapeutic mechanism for modulating the inflammatory response after the burn injurythat may improve wound healing.
