Clinical Trial Summary

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.

Description:

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.

Intervention

Other:
• NEOX® CORD 1K
Amniotic Membrane Tissue is fetal membrane tissue that comprises the innermost layer of the human placenta, and the outermost lining of the umbilical cord. In addition to amniotic membrane, the umbilical cord also contains Wharton's jelly, a rich source of proteoglycans and growth factors. These tissues share the same cell origin as the fetus and serve to protect the fetus during development. This product does not contain live cells.

Procedure:
• Standard of Care (Pressure Bandage)
Standard of Care wound, pressure dressing applied as needed at each visit.
