Experimental treatments in clinical trials for diabetic foot ulcers: wound healers in the pipeline

Abstract

ABSTRACT Introduction Diabetes affects 400 million people globally and patients and causes nephropathy, neuropathy, and vascular disease. Amongst these complications, diabetic foot ulcers remain a substantial problem for patients and clinicians. Aggressive wound care and antibiotics remain important for the healing of these chronic wounds, but even when treated these chronic ulcers can lead to infection and amputations Areas covered This paper reviews the pathophysiology of diabetic foot ulcers and the current management strategies. Then, it discusses novel therapeutics such as topical oxygen therapy as well as autologous patches and macrophage creams. Expert opinion Diabetic foot ulcers are a substantial problem for patients and clinicians. Early identification, aggressive wound care, and normoglycemia remain the standard of care, however when these fail it is important to adapt. Since each patient and wound vary drastically we believe they should be treated as such. For patient with intact perfusion, topical ON101 and sucrose octasulfate creams can help. While patient with peripheral arterial disease should consider topical oxygen therapy as an adjunct. However, as scientists gain a better understanding of the pathophysiology behind DFUs, the hope is that this new wave of therapeutics will emerge.
