3. Foot ulcer located in the plantar or dorsal, with ulcer size between1.5 cm2 and 15 cm2.
4. Ulcer, Graded II by Wagner grade, and extended to muscle periosteum, muscle, tendon, or joint capsule, but not to bone.
5. Ulcer is free of necrotic debris,exhibits no signs of clinical infection.
6. Ulcer area blood circulation meets 1 of the following criteria:

4. The longest dimension of the index wound exceeds 15 cm at the baseline visit.
5. Patient with skin lesion confirmed by biopsy (when Investigator deems suspicious) and then judged by Investigator to be an etiology other than diabetic foot ulcer (i.e.,example skin cancer in situ, pyoderma).
6. Current evidence of active charcot, osteomyelitis, cellulitis, or evidence of other infection including fever or purulentdrainage from wound site.
