Chronic Ulcer clinical trials at University of California Health

- The study is a multi-center, prospective, randomized, controlled, single blinded clinical study consisting of 150 subjects from up to 20 centers. - The subjects are randomized to receive 1 of 2 treatments, either with ActiGraft and standard of care (SOC) or with SOC alone. - The target ulcers are evaluated weekly by the investigator. The subject is treated once a week, to receive weekly applications of the ActiGraft + SOC or SOC until for up to 12 weeks or until the study ulcer has completely healed (i.e., 100% closure as assessed by the Investigator and blinded assessor and confirmed 2 weeks later at the healing confirmation visit (HCV). One additional visit per week is optional for both arms, for the purpose of changing only (1) the secondary dressing in the ActiGraft arm or (2) change the standard of care dressing in the control arm. - Immediately after the study ulcer is confirmed as completely healed, subjects will enter the 12-week Follow-up Phase. During the Follow-Up phase, subjects will be evaluated twice during the first month and then monthly for two additional visits every 4 weeks until the completion of the 12-week Follow-up Phase.
