• 1. Dorsal transcutaneous oxygen measurement (TCOM/TcPO2) measurement of
• 2. Ankle Branchial Index (ABI) between 0.7 and 1.3 within 90 days of Screening (Visit 1 or 2) using the extremity on which the index ulcer is located
• 3. Arterial Doppler ultrasound evaluating for biphasic or triphasic dorsalis pedis and/or posterior tibial vessels at the level of the ankle or a TBI (Toe Brachial Index) of \> 0.6 is acceptable within 90 days of Screening (Visit 1 or 2)
• 10. The index ulcer has been offloaded with protocol defined offloading device during Screening (Run-In) period through Randomization/Baseline visit.
• 11. Must meet one of the following criteria:
• 12. Ability to comply with the study protocol as per investigator discretion
• 1. Actively undergoing chemotherapy treatment (localized radiation treatment is allowed if it is not on the DFU wound site and in remission based on scans, bloodwork or some other kind of test, such as a breast biopsy or a bone marrow biopsy)
• 2. Ulceration with exposed tendon, capsule, or bone
• 3. Suspicion of bone or joint infection by clinical or other criteria as per STONEES criteria below:
• 4. Unable or unwilling to utilize the protocol defined offloading device
• 5. Subjects who have undergone endovascular or open revascularization of the index limb within the last 30 days from Screening.
• 6. Index ulcer has decreased in area by ≥ 30% between Screening (Visit 1) and Baseline visits
• 7. Any subject that is currently on/or requires oral, systemic or topical antibiotics, or is anticipated to require their use during the course of the study
• 8. Any subject that has vascular compromise requiring surgical intervention or has undergone vascular reconstruction or angioplasty less than 1 month prior to randomization. Any planned surgical procedures during the study participation

• 14. Any subject that would be unable to safely monitor the infection status of the index ulcer at home and return for scheduled visits
• 15. History of immunosuppression or taking immunosuppressive agents including systemic corticosteroids, except stable daily doses of 5 mg/day or less for chronic conditions for up to 5 days
• 16. Any subject with a life expectancy ≤ 6 months

• 18. Use of investigational drugs or biologics within 28 days prior to screening (Visit 1 or 2)
• 19. History of a concurrent condition that, in the Investigator's opinion, would jeopardize the safety of the subject or compliance with the protocol
• 20. Known or suspected active abuse of alcohol, or non-prescription drugs
• 21. Participation in another interventional clinical study or study in the past 30 days of Screening (Visit 1 or 2) or concurrent participation in another interventional clinical study
