Patients were followed until closure or 12 weeks. Patients, caretakers, treating physicians and independent evaluators were blinded to the study arm. All patients received identical offloading, debridement, dressings and follow-up. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> We enrolled 146 people with DFUs (77% male, aged 56.3\u00b112.4 years). A significantly higher proportion (195%) of DFUs healed in the CDO arm compared with placebo (32.4% versus 16.7%, p=0.033). The time to 50% DFU closure was significantly shorter in patients that received CDO therapy (mean 18.4 versus 28.9 days, p=0.001). There were no differences in overall adverse events (p=0.66) or ulcer-related adverse events (p=0.30) in the active and placebo treatment groups. The relative performance of active CDO over placebo became greater when used in larger wounds (273%), in more chronic wounds (334%) and in weight bearing wounds (465%). <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> The results of this study demonstrate that CDO leads to higher proportion of healed DFUs (p=0.033) and a faster time to closure compared with placebo in people with DFUs (p=0.015). Relative performance did not vary significantly with wound size (p=0.80), but revealed better relative performance in more chronic wounds (p=0.008) and in weight-bearing wounds (p=0.003).
