The efficacy of a bilayered, living skin construct (
APLIGRAF(R) [Graftskin]) was evaluated in patients (n = 120) with hard- to-heal venous
leg ulcers of greater than 1 year's duration. The study was prospective, randomized, and controlled. Patients received Graftskin plus compression
therapy, or standard compression
therapy (active control). Patients were evaluated for frequency and time to complete (100%)
wound closure. Treatment with Graftskin was significantly more effective than active control in the percentage of patients healed by 6 months (47% vs. 19%; p < 0.005) and the median time to complete
wound closure (p < 0.005). Analysis with multivariate regression methods, adjusting for factors generally thought to influence wound healing (duration, baseline area, depth, location, fibrinous
wound bed, and
infection), showed that patients treated with Graftskin were twice as likely to achieve complete
wound closure by 6 months (p < 0.005), and over 60% more effective in achieving
wound closure than active control (p < 0.01). These data indicate that Graftskin is an effective treatment for
venous ulcers of greater than 1 year's duration.
