• At least 18 years old
• Have adequate vascular perfusion to the surgical site limb as defined by one of the following in order of preference; Ankle Brachial Pressure Index (ABI) > 0.65 < 1.3; Toe Pressure of greater than 40mmHg; TcPO2 of greater than 40mmGg
• Skin Perfusion Pressure (SPP) > 30. (Calculations will be made using measurements from both dorsalis pedis arteries and posterior tibial arteries of affected limbs)
• Presence of a diabetic foot ulcer extending through the full thickness of the skin but not down to muscle, tendon or bone. The largest ulcer will be designated the index ulcer and the only one included in the study. If other ulcerations are present on the same leg they have to be more than 2 cm apart from the index ulcer
• Study ulcer (i.e. current episode of ulceration) has been present for at least one month prior to the initial screening visit, and is excluded if it has undergone 1 month of continuous high strength offloading therapy over its duration
• Study ulcer is a minimum of 1 cm2 and a maximum of 25 cm2 at the application visit
• The target ulcer has been treated with standard of care and offloading therapy for at least 14 days prior to application
• Ulcer has a clean, granulating base with minimal adherent slough at the randomization visit
• Females of childbearing potential must be willing to use acceptable methods of contraception (birth control pills, barriers, or abstinence)
• Patient understands and is willing to participate in the clinical study and can comply with weekly visits and the follow-up regimen
• Patient has read and signed the IRB/IEC approved Informed Consent Form before screening procedures are undertaken

• Patients with a history of more than two weeks treatment with immunosuppressants (including systemic corticosteroids), cytotoxic chemotherapy, or application of topical steroids to the ulcer surface within one month prior to initial screening, or who receive such medications during the screening period, or who are anticipated to require such medications during the course of the study
• Patients on any investigational drug(s) or therapeutic device(s) within 30 days preceding Screening. (All Covid-19 Vaccines are exempt as investigational drugs under this protocol)
• Study ulcer has been previously treated with tissue engineered materials (e.g., Apligraf® or Dermagraft®) or other scaffold materials (e.g. Oasis, Matristem) within the last 30 days
• Currently taking medications which could affect graft incorporation. (supervising physicians' discretion)
• Study ulcer(s) deemed by the investigator to be caused by a medical condition other than diabetes
• Study ulcer exhibits clinical signs and symptoms of infection
• Study ulcer, in the opinion of the investigator, is suspicious for cancer should undergo an ulcer biopsy to rule out a carcinoma of the ulcer
• History of radiation at the ulcer site
• Study ulcer requiring negative pressure wound therapy or hyperbaric oxygen during the course of the trial
• The presence of any condition(s) which seriously compromises the subject's ability to complete this study, or has a known history of poor adherence with medical treatment
• Ulcers on the dorsum of the foot or with more than 50% of the ulcer below the malleolus are excluded
• Patients who are unable to understand the aims and objectives of the trial
• Pregnant or breast feeding
