dHACM In the Treatment of Diabetic Foot Ulcers

Study Overview
=================
Brief Summary
-----------------
A single-centered, non-randomized study with approximately 20 subjects that will be seen for up to 12 weeks, each receiving the EpiFix plus standard of care. Safety and effectiveness will be monitored throughout the study.

Detailed Description
-----------------
Approximately 20 subjects will be enrolled in this study. Subjects will be seen for up to12 weeks unless 100% epithelialization of the index wound and two subsequent healing confirmation visits have been achieved prior to week 12. Each subject will receive a weekly application of the EpiFix plus standard of care until 100% epithelialization is achieved. The subjects will be evaluated for efficacy and safety during the course of the trial.

Study ulcer has been previously treated with tissue engineered materials (e.g. Apligraf® or Dermagraft®), EpiFix®, or other scaffold materials (e.g. Oasis®, MatriStem®) within the last 30 days Subjects with the following lab values at Day 0: HbA1C ≥ 12% at any time within previous 60 days Serum Creatinine ≥ 3.0mg/dl within last 6 months Therapy Related Exclusions: Subjects previously or currently enrolled in this study Subjects being treated with investigational drug(s) or investigational therapeutic device(s) within 30 days Subjects currently receiving radiation therapy or chemotherapy Currently being treated with antibiotics Other Exclusion Criteria: Active Charcot deformity or major structural abnormalities of the foot Known allergy to Gentamicin sulfate or Streptomycin sulfate Subjects diagnosed with autoimmune connective tissue diseases Any pathology that would limit the blood supply and compromise healing Known history of poor compliance with medical treatments Subjects who are known to be pregnant, plan to become pregnant, or are breast feeding
