Standard of Care

DermGEN™

Arm Description

The standard of care includes physical examination, wound debridement, total cast or offloading boot, non-adherent dressing (PolyMem®) for wound covering, weekly visit for ongoing assessment

5. Study Description

Brief Summary
The study will examine the effectiveness of a decellularized dermal matrix (i.e., DermGEN™) in improving wound healing, quality of life and associated costs of treatment of DFUs in First Nations people living in the Northwestern Ontario Communities. First Nations people with active diabetic foot (DFU) ulcer attending a wound care clinic located at the Rainy River district office. An interventional, two-arm, randomized, prospective study of (1) standard of care (control) vs. (2) DermGEN™ - a decellularized dermal matrix (treatment) will be used in the treatment and management of DFU. Patients will be randomized to each arm (n=60 per arm) based on power calculations using data from our Pilot study.

6. Conditions and Keywords

Primary Disease or Condition Being Studied in the Trial, or the Focus of the Study

Parallel Assignment
Model Description
An interventional, two-arm, randomized, prospective study of (1) standard of care (control) vs. (2) DermGEN™ - a decellularized dermal matrix (treatment) will be used in the treatment and management of DFU. Patients will be randomized to each arm (n=60 per arm) based on power calculations using data from our Pilot study.
Masking
None (Open Label)
Masking Description
Masking cannot be accomplished as one intervention will require application of an advanced wound care product (DermGEN™) and the other arm (control) will not receive the intervention. This will be quite obvious to all.
