Estimated foot ulcer surface area, L x W, between ≥ 0.70 cm^2 and ≤ 5.0 cm^2 as measured at Treatment Day 1 Any subject who does not meet this criterion will not be eligible for randomization.

Active osteomyelitis of the study foot
Active connective tissue disease
Study ulcers with an etiology not related to diabetes (e.g., thermal, chemical, radiation insult)
History of active Charcot foot of the study foot within 6 months of screening
Treatment with systemic corticosteroids (equivalent to > 10 mg/day of prednisone) or immunosuppressive or chemotherapeutic agents within 14 days prior to the first study drug gel application or likelihood to receive one of these therapies during study participation
