Arms Assigned Interventions
PriMatrix applied to appropriately debrided wound bed and covered with a non-adherent dressing. Dressings applied to maintain moist wound therapy.
Device: PriMatrix
Following sharp debridement, application of PriMatrix dermal repair scaffold in conjunction with moist wound therapy
Active Comparator: Standard of Care
Non adherent dressing applied to appropriately debrided wound bed and moist wound therapy maintained.
Other: Standard of Care
Following sharp debridement, moist wound therapy

Detailed Description:

Subjects will be considered for screening upon meeting initial eligibility criteria. After a 2 week screening period, subject will be randomized and enrolled if additional criteria is met. In particular, if wound size has decreased by greater than 40%, subject will be considered a screen fail and randomization will not take place. If all criteria including wound size at Week 3 is met, subject will be randomized and enrolled. Subjects will return weekly for a maximum of 12 weeks, or whenever healing occurs and then once more for a confirmation of healing. Week 24 will consist of a phone call to the subject to complete QOL surveys.
