Only PEDIS 2 infections are permitted - Mild superficial skin and soft tissue infections with no systemic manifestations and involving: • Erythema extending ≥2 cm from the wound margin, and/or tissue deeper than skin and subcutaneous tissues (e.g., tendon, muscle, joint, and bone) IC-4 Adequate arterial supply in the lower extremity as defined by Wound, Ischemia, foot Infection (WIfI) Ischemia grade 0-1; 1. Palpable foot pulse with biphasic or triphasic pedal Doppler waveforms, AND 2. Ankle Brachial Index (ABI) \>0.6 OR Toe Brachial Index (TBI) \>0.5, OR 3. Toe pressure \>40mmHg Exclusion Criteria: EC-1 Ulcers that are tunnelling or have cavities (\>10mm in depth) EC-2 An ulcer that is actively bleeding. Subjects may be re-screened once active bleeding has stopped EC-3 Subjects taking any medication known to inhibit wound closure including chemotherapy and immunomodulatory biological agents.
