Decellularized dermis (DCD) allografts have been shown to be effective in improving healing rates of diabetic foot ulcers in RCTs. The DAVE RCT aimed to determine whether DCD is an effective, safe, and cost-effective treatment adjunct for VLUs.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>This was a multicentre RCT performed in the UK. Patients with lower limb ulcers \u226518 years with VLU, venous incompetence on duplex ultrasound, an ankle : brachial pressure index \u2265 0.8 and an index VLU present for at least 3 months and \u22652\u2005cm2 in size were included. Patients were randomized to either the intervention (DCD graft and standard of care) or control arm (standard of care alone). The primary outcome was the proportion of patients with a healed index ulcer at 12 weeks.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>From October 2019 to October 2022, 36 and 35 participants were randomized into the intervention and control arms respectively. Patient characteristics at baseline were similar between groups. Healing was recorded in 5.7% of the intervention group and 15.2% in the control group (OR 0.34, 95% c.i. 0.03 to 2.31). There were no significant differences in the secondary outcomes including the percentage change in ulcer area, time to healing, recurrence rates, and QoL. There were five serious adverse events attributed to DCD application. Early trial termination was advised after the interim data analysis due to a lower-than-expected primary outcome rate (11.3%).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Decellularized dermis grafts did not improve healing rates of venous leg ulcers, although the trial was terminated early due to poor healing rates in both the intervention and control arms.
