An Index Ulcer that is chronic (defined as present for \> 4 weeks, but not present for more than 52 weeks at the Screening Visit) 4. Index Ulcer is located below the malleolus 5. The Index Ulcer is a Diabetic Foot Ulcer (DFU) greater than 3 cm2, inclusive, at the Screening Visit 6. The longest length and longest width measurements for the Index Ulcer are no less than 1 cm each at the Screening Visit 7. The Index Ulcer extends into the dermis or subcutaneous tissue without evidence of exposed muscle, tendon, bone, or joint capsule 8. Wound is free of necrotic debris 9. Patient has adequate circulation to the foot as documented by ABI or TBI
