  • Time to healing [ Time Frame: 12 weeks ]

Enrollment: 0
Study Start Date: January 2008
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Experimental Arm (Internal Control)

One-half of ulcer receives negative pressure wound therapy

One-half of ulcer receives a fetal bovine collagen bioscaffold (PriMatrix, TEI Biosciences, Boston, MA) in addition to the same negative pressure wound therapy

Device: PriMatrix
Dermal Repair Scaffold


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Adult Type 1 or 2 diabetic patients that present with foot ulcers.
  • Ulcer size of at least 3 centimeters (cm) in diameter at its widest dimension.
  • Ulcer depth: Full thickness (absence of all epithelial layers or deeper)
  • Adequate perfusion (at least one palpable pedal pulse or pedal bypass graft)
  • All ulcer durations will be eligible
  • Patients currently receiving NPWT for a diabetic foot ulcer
  • Patients must be appropriate NPWT candidates and be willing and able to sleep, ambulate, and rest with the NPWT unit in place.

Exclusion Criteria:

  • Active foot infections
  • Presence of any serious disease including end-stage renal failure requiring dialysis or renal transplantation or active malignant disease requiring treatment which seriously compromises the patient's ability to complete this study
  • Patients who are pregnant
  • Allergies to any material contained within the NPWT or bioscaffold
  • Any condition that would exclude NPWT use including but not limited to active bleeding, presence of malignancy in the wound or inability to follow any of the NPWT safety guidelines
