Spray-On Cell-Based Therapy and Leg Ulcers
The results of a multicenter, phase-2 trial that shows the efficacy of a spray-on, cell-based treatment of venous leg ulcers was published August 2 in Lancet. The study, lead-authored by Robert S. Kirsner MD, of the Leonard M. Miller School of Medicine in Miami, tested the ability of a spray-on application of growth-arrested neonatal keratinocytes and fibroblasts to self-assemble into a fibrin matrix and heal leg ulcers. The study results show a significantly greater reduction in wound area than the control group. The treatment also accelerated wound closure by an average of 21 days compared to the control group.
The study enrolled adult outpatients with up to 3 ulcers from 28 centers in the United States and Canada. The patients had at least 1 ulcer measuring from 2 cm2 to 12 cm2 in area, which had persisted for from 6 to 104 weeks. Treatment was sprayed on the wound every 7 or 14 days. The spray-applied cell therapy is dosed at 0.5 × 106 cells per mL every 14 days. The 228 participants were randomly assigned to 1 of 5 groups: vehicle alone (50 patients), 0.5 × 106 cells every 14 days (46 patients), 0.5 × 106 cells every 7 days (43 patients), 5.0 × 106 cells every 14 days (44 patients), or 5.0 × 106 cells every 7 days (45 patients). All patients were also treated with compression bandages.
This new treatment would allow for healing without a new wound where the graft is taken from, as well as immediate treatment, without the preparation time required for skin grafts.
