A Multi-center, Randomized, Parallel, Crossover Design Study of Non-healing Diabetic Foot Ulcers, Treated With Cryopreserved, Umbilical Cord Allograft (NEOX® CORD 1K) Versus Standard of Care That Are Followed for 12 Weeks

In this randomized, multi-center, cross-over study, the efficacy and safety of NEOX® CORD 1K
will be evaluated in patients suffering from non-healing diabetic foot ulcers. NEOX® CORD 1K
is a cryopreserved human Amniotic Membrane and Umbilical Cord (AM/UC) matrix intended for
use as a wound covering for dermal ulcers and defects. It is designated as a Human Cell &
Tissue Product (HCT/P) by the U.S. FDA.

Patients identified for the study will have a non-healing diabetic ulcer, between 1-25cm² in
size. The patient's wound(s) will be monitored for 2 weeks to document the wound pathology.
Patients with less than 30% wound area reduction during the 2 week screening period and who
meet all of the inclusion and none of the exclusion criteria, will be enrolled in the study.
All patients will be assigned to a study or control group and undergo sharp debridement.
NEOX® CORD 1K matrix will be applied to the treatment group on the day of debridement,
covered with a wound veil, and standard dressing. Both groups will be monitored weekly, and
the % decrease in wound size will be recorded at Baseline and Weeks 1, 2, 3, 4, 6, 8 and 12.
If the wound is not progressing, additional application of NEOX® CORD 1K may be applied. The
time to complete closure will be recorded for both groups. The study duration will be 12
weeks. Subjects in the control group that continue to suffer a non-healing wound at the week
12 visit will be offered an opportunity to cross-over to NEOX treatment and followed for an
additional 12 weeks.

Inclusion Criteria:

1. Between 18 years and 80 years of age inclusive

2. Confirmed diagnosis of Type I or Type II Diabetes

3. Males and Females diagnosed with a diabetic foot ulcer that is 1-25cm²

4. At least one foot ulcer that is UT Grade IA

5. Evidence of proper circulation which includes: An Index Ulcer defined as chronic
(presence of wound for > 4 weeks) but not present for more than 52 weeks at the
Screening Visit

6. The Index Ulcer is located below the malleoli on the plantar or dorsal surface of the
foot

7. The Index Ulcer extends into the dermis or subcutaneous tissue with no evidence of
exposed muscle, tendon, bone, or joint capsule

8. Wound is free of necrotic debris and clinical signs of infection

9. Patient has adequate circulation to the foot

10. In patients with non-compressible ankle vessels there is adequate flow to the foot.

Exclusion Criteria:

1. The Index Ulcer is of non-diabetic pathophysiology and/or over an active Charcot
deformity

2. The Index Ulcer is UT Grade IB or higher (worsening)

3. Gangrene is present on any part of the affected foot

4. The longest dimension of the Index Ulcer exceeds 5 cm at the Baseline Visit

5. Patient is currently receiving renal dialysis

6. Patient has a glycated hemoglobin A1c (HbA1c) level of > 12%

7. Patient has significant renal impairment

8. Chronic oral steroid use > 7.5 mg daily

9. Requiring intravenous (IV) antibiotics to treat the index wound infection

10. Patient has an ulcer within 15cm of the Index Ulcer identified for study
consideration

11. Patient is receiving oral or parenteral corticosteroids, immunosuppressive or
cytotoxic agents

12. Patient is Human Immunodeficiency Virus (HIV) positive or has Acquired Immune
Deficiency Syndrome (AIDS)

13. Current evidence of osteomyelitis, cellulitis, or other evidence of infection
including fever or purulent drainage from the wound site

14. Patient has active malignancy other than non-melanoma skin cancer

15. Patient's Index Ulcer has decreased by ≥ 30% during 2-week screening period

16. Patient has untreated alcohol or substance abuse at the time of screening

17. Pregnant women

18. Patient is currently enrolled or participated in another investigational device,
drug, or biologic trial within 60 days of screening

19. Patient has allergy to primary or secondary dressing materials used in this trial

20. Patient has an allergy to amphotericin-B or Dulbecco's Modified Eagle Medium (DMEM)

21. Patient has had within the last 30 days, or is currently undergoing, or is planning
for wound treatments with enzymes, growth factors, living skin, dermal substitutes or
other advanced biological therapies
