Interventional
Description of intervention(s) / exposure
Trial participants will receive between 3-7 treatments with CANN001, a hydrogel dressing containing 0.3% 2deoxy-D-ribose. Each patient will receive 3-7 dressings with a dressing change every 48 hours (ascending dose of 3, 5 and finally 7 dressings applied with 6 participants in each group (1:1:1 for 3:5:7 dressings respectively). Dressings will be applied in clinic by a podiatrist on each occasion.

Summary
Brief summary
Diabetic foot ulcers are a chronic wound and the pathophysiology is linked to neuropathy, infection and peripheral vascular disease. This peripheral vascular disease, linked to diabetes, prevents ulcer closure and leads to susceptibility to infection. 2-deoxy-D-ribose (2dDr) is known to promote vascularisation and may therefore increase angiogenesis when administered to a DFU and through this mechanism promote wound closure.

The planned study will investigate if CANN001 (2dDr containing hydrogel) is safe in patients with diabetic foot ulcers and whether 2dDr may promote DFU healing and localised wound angiogenesis/neovascularisation through increasing local expression of VEGF.
