Detailed Description
Primary objective is to compare time required to achieve wound bed preparation between Subjects randomized to receive V.A.C. NPWT or MWT. Subjects with ALL the following are eligible for clinical trial enrollment:
Evidence of therapy controlled diabetes, as defined by the American Diabetes Association (ADA) of HbA1C less than or equal to 10%, within 90 days of screen or at time of screening, greater than or equal to 18 years of age, forefoot amputation less than or equal to 10 days old distal to the transmetatarsal level, not extending beyond the Lisfranc joint, receiving MWT allowed in the protocol for treatment of the study wound, Wound surface area measured as length x width of greater than or equal to 10 cm2, Subject is willing and able to provide written informed consent and comply with follow-up visit schedule and maintain a treatment diary, Adequate nutrition to enable wound healing as evidenced by a prealbumin level of greater than or equal to 16 mg/dl or an albumin level of greater than or equal to 3 g/dl within 7 days of screening or at the screening visit, Adequate perfusion in the affected extremity as evidenced by grade 1 or 2 PVR waveform as confirmed at screening, Non-pregnant female Subject of childbearing potential confirmed negative by serum HCG or surgically sterilized or unable to conceive.

---|---|
Experimental: V.A.C. Therapy
Negative Pressure Wound Therapy (NPWT) distrubtes negative pressre across a wound base by means of a specially engineered dressing with the specific intent to help promote wound healing.

Active Comparator: Moist Wound Therapy (MWT)
t wound therapy (MWT) is a widely used treatment modality that demonstrates benefit through the facilitation of a moist wound environment, which is known to promote faster relative wound healing compared to wounds exposed to air.
