Reporting Groups

	Description
Epiflo Treatment	The cohort will comprise of 2 populations: the Treatment Arm of up to 90 subjects; and the Control Arm of up to 90 subjects, in order to collect 120 invaluable subjects. The Treatment Arm includes subjects with DFU who will receive EPIFLO in addition to standard wound care therapy during the Treatment Period. Epiflo: During the Treatment Period, subjects will be administered EPIFLO (either working units or sham units per randomization schedule) in conjunction with standard wound therapy regimen consisting of aggressive debridement, wound cleansing, wound dressing, for a period of 12 weeks, or until the wound completely closes, whichever event occurs first.
Sham Device	The cohort will comprise of 2 populations: the Treatment Arm of up to 90 subjects; and the Control Arm of up to 90 subjects, in order to collect 120 invaluable subjects. Control Arm includes subjects with Diabetic Foot Ulcers who will receive sham units of EPIFLO along with standard wound care therapy during the treatment Period. Moist Wound Therapy: During the Treatment Period, subjects will be administered EPIFLO (either working units or sham units per randomization schedule) in conjunction with standard wound therapy regimen consisting of aggressive debridement, wound cleansing, wound dressing, for a period of 12 weeks, or until the wound completely closes, whichever event occurs first.
