• Have an adequate circulation to the affected lower extremity, defined as at least one of the criteria within the previous 60 days:

• Transcutaneous oxygen measurement at the dorsum of the foot greater or equal to 30 mm Hg
• Ankle-brachial index (ABI) ranging from 0.8 to 1.2
• At least biphasic Doppler arterial waveforms at the dorsalis pedis and posterior tibial arteries
• Have the ability to comply with off-loading and dressing change requirements
• Have the ability to understand the requirements of the study, have provided written informed consent as evidenced by signature on an informed consent form (ICF) approved by an institutional review board (IRB), and agree to abide by the study restrictions and return to the site for the required assessments
• Have provided written authorization for use and disclosure of protected health information
• Have a life expectancy of greater than 6 months

Exclusion criteria

To be eligible for entry into the study, the subject must not meet any of the exclusion criteria listed below:

• Be pregnant or lactating
• Subjects with a target wound <30 days old at Screening whose wound area has decreased in size ≥50% between the Screening and Baseline Visits (assessed at Baseline/Visit 2)
• Have a circulating hemoglobin A1c exceeding 12% within 90 days of the Screening Visit (assessed at Screening/Visit 1 for subjects with labs collected <30 days of screening; assessed at Baseline/Visit 2 for subjects with labs collected at screening)
• Have a serum creatinine concentration of 3.0 mg/dL or greater within 30 days prior to screening (assessed at Screening/Visit 1 for subjects with labs collected <30 days of screening; assessed at Baseline/Visit 2 for subjects with labs collected at screening)
• Have a sensitivity to either of the following antibiotics: lincomycin, gentamicin, polymyxin B, or vancomycin
• Have a sensitivity to polysorbate 20, N-lauroyl sarcosinate, benzonase or glycerol
• Have the wound treated with biomedical or topical growth factors within the previous 30 days before the Screening Visit
• Need for any additional concomitant dressing material other than the ones approved for this study
• Have clinical signs of an infection at the study ulcer site (assessed at BOTH Screening/Visit 1 and Baseline/Visit 2)
• Have the inability to tolerate an off-loading boot
• Have a known or suspected disease of the immune system
• Have an active or untreated malignancy or active, uncontrolled connective tissue disease
• Had a treatment with immunosuppressive or chemotherapeutic agents, radiotherapy or systemic corticosteroids less than 30 days before the Baseline Visit
• Have presence of necrosis, purulence, or sinus tracts that cannot be removed by debridement (assessed at Baseline/Visit 2)
• Has undergone a revascularization procedure aimed at increasing blood flow in the treatment target limb less than 4 weeks before the Baseline Visit
• Have serum aspartate aminotransferase, alanine aminotransferase, or alkaline phosphatase levels greater than three times the normal upper limit within 30 days prior to screening (assessed at Screening/Visit 1 if subject had labs collected <30 days of screening; assessed at Baseline/Visit 2 if subject had labs collected at screening)
• Have active Charcot disease
• Have undergone treatment with a living skin equivalent within the last 4 weeks before screening
• Have ongoing evidence of peripheral vascular disease, including greater than one nonpalpable pulse on either foot
• Have the presence of any condition that in the opinion of the investigator places the subject at undue risk or potentially jeopardizes the quality of the data to be generated
