Randomized Controlled Trial Multicenter Study Comparative Study
Intra-lesional injections of recombinant human epidermal growth factor promote granulation and healing in advanced diabetic foot ulcers: multicenter, randomised, placebo-controlled, double-blind study.
A multicenter, double-blind, placebo-controlled trial was carried out to evaluate the intra-lesional infiltration of recombinant epidermal growth factor (EGF) in Wagner's grade 3 or 4 diabetic foot ulcers (DFUs). Subjects (149) were randomised to receive EGF (75 or 25 microg) or placebo, three times per week for 8 weeks and standard good wound care. The main endpoint was granulation tissue covering > or = 50% of the ulcer at 2 weeks. ⋯ Multivariate analyses yielded that they were significantly enhanced by 75 microg EGF treatment and neuropathic versus ischemic ulcers. Most adverse events were mild and no drug-related severe adverse reactions were reported. It was concluded that recombinant human EGF (rhEGF) local injections offer a favourable risk-benefit balance in patients with advanced DFU.
