  2. Ulcer is a partial or full thickness diabetic foot ulcer without capsule/tendon/bone exposure
  3. Ulcer does not have tunneling, undermining, or sinus tracts that necessitates surgical OR debridement and/or penetrates to capsule/tendon/bone
  4. Ulcer is located on the foot or ankle (with no portion above the top of the malleolus)
  5. Ulcer size (area) is greater than equal to 1 cm2 and less than equal to 12 cm2 post-debridement

• Have a minimum 4cm margin between the qualifying study ulcer and any other ulcer on that same foot, post-debridement

  (a) If the subject has more than one ulcer that meets eligibility criteria, the ulcer designated as the study ulcer will be at the discretion of the investigator

• Have adequate vascular perfusion of the affected limb as defined by at least one of the following within the past 60 days:

  1. Ankle-Brachial Index (ABI) greater than equal to 0.7 and less than equal to 1.2, performed within 60 days of screening,
  2. Toe pressure (plethysmography) > 40 mmHg at time of screening, or
  3. TcPO2 > 50 mmHg at time of screening
• Be willing and able to maintain required applicable dressing changes as well as study required off-loading/protective device for the duration of the study
• Have a study wound severity Wagner I or II

Exclusion Criteria:

• Previously randomized and treated under this clinical study protocol
• Patients with a known history of poor compliance with medical treatments
• Suspected or confirmed gangrene or ulcer infection of the study ulcer or is receiving systemic/IV antibiotics at the time of randomization
• Suspected or confirmed osteomyelitis of the foot with the study ulcer
• Participated in another clinical trial involving a device or a systemically administered investigational study drug/treatment within 28 days of randomization
• Received within 28 days of signing Informed Consent Form, or is scheduled to receive during study participation, a medication or treatment which is known to interfere with or affect the rate and quality of ulcer healing (e.g., systemic steroids, immunosuppressive therapy, autoimmune disease therapy, dialysis, radiation therapy to the foot, vascular surgery, angioplasty, or thrombolysis)
• History of bone cancer or metastatic disease of the affected limb, radiation therapy to the foot, or has had chemotherapy (i.e., systemic steroids, anti-rheumatics, TNF inhibitors, active chemotherapy, immunosuppressive therapy, autoimmune disease therapy) within 12 months prior to signing Informed Consent Form allowing trial participation
• In the opinion of the investigator, the subject has a history of, or is currently diagnosed with, any illness or condition, other than diabetes, that could interfere with ulcer healing (e.g., end-stage renal disease, severe malnutrition, liver disease, aplastic anemia, connective tissue disorder, acquired immune deficiency syndrome, HIV positive, or sickle cell anemia)
• In the opinion of the investigator, the subject has unstable Charcot foot or Charcot with bony prominence that could inhibit ulcer healing
• Have ulcers secondary to a disease other than diabetes (e.g., vasculitis, neoplasms, or hematological disorders)
• In the opinion of the investigator, the subject has excessive lymphedema that could interfere with off-loading and/or ulcer healing
• Study Ulcer has received ulcer dressings that included growth factors, engineered tissues, or skin substitutes within 28 days of randomization, or is scheduled to receive such treatment during the study (e.g., Regranex, Dermagraft, Apligraf, EpiFix, Grafix, GraftJacket, OASIS, Omnigraft, or Integra BMWD)
