Overview

The purpose of this study is to compare Pellograft to standard of care modalities in treating diabetic foot ulcers in human subjects, and to compare Sanograft to standard of care in treating venous leg ulcers. The study will demonstrate wound healing outcomes with comparators including time to wound epithelialization, decrease in wound size, and total number of study product applications towards healing outcome. This information is important to the Centers for Medicare and Medicaid Services (CMS) and other payors in determining coverage policy and reimbursement for this product category.
