Abstract

Diabetic foot ulcers (DFUs) are at risk for detrimental complications even with current, standard of care (SOC) treatments. The primary objective of this randomised controlled trial was to compare a unique resorbable glass microfiber matrix (Mirragen; Advanced Wound Matrix [BBGFM]; ETS Wound Care, Rolla, Missouri) compared with a standard of care group (SOC, collagen alginate dressing) at 12 weeks. Both groups received standard diabetic foot care including glucose monitoring, weekly debridements when needed and an offloading device. The primary endpoint was proportion of full-thickness, non-infected, non-ischaemic wounds healed at 12 weeks, with secondary endpoints including percent area reduction (PAR) and changes in Semmes-Weinstein monofilament testing. The result illustrated in the intent-to-treat analysis at 12 weeks showed that 70% (14/20) of the BBGFM-treated DFUs healed compared with 25% (5/20) treated with SOC alone (adjusted P =.006). Mean PAR at 12 weeks was 79% in the BBGFM group compared with 37% in the SOC group (adjusted P =.027). Mean change in neuropathic score between baseline and up to 12 weeks of treatment was 2.0 in the BBGFM group compared with −0.6 in the SOC group where positive improvement in scores are better (adjusted P =.008). The mean number of BBGFM applications was 6.0. In conclusion, adding BBGFM to SOC significantly improved wound healing with no adverse events related to treatment compared with SOC alone.
