Brief Summary:
A prospective, randomized, controlled, clinical study to establish clinical based evidence of PRP Concepts Fibrin Bio-Matrix and compare its performance with the usual and customary practice for the treatment of Wagner 1 or 2 DFUs.

Condition or disease Intervention/treatment Phase
Diabetic Foot Ulcers Device: PRP Concepts Fibrin Bio-Matrix Other: Usual and Customary Practice Phase 2 Phase 3

Detailed Description:
This is a prospective, randomized, single-blind, controlled, multi-center study for subjects undergoing DFU treatment. Qualified subjects will be randomized (1:1); test group (PRP Concepts Fibrin Bio-Matrix) and control group (usual and customary practice). The study will consist of 3 periods: a screening period, an active treatment period, and a follow-up period (if healed). Approximately 250 subjects will be enrolled. Subjects will be ≥18 years of age with a chronic Wagner grade 1 or 2 DFU (greater than 1 month duration). Each subject will be enrolled in the active treatment period for up to 12 weeks, or to closure of wound with a confirmatory visit 2 weeks after wound closure, whether such closure occurs at 12 weeks or earlier.

Primary Outcome Measures :
  1. Time to complete wound closure [ Time Frame: 12 weeks ]
    Complete wound closure is defined as full epithelialization of the wound with the absence of drainage, durability confirmed at 2 weeks

  2. Percent of wounds healed [ Time Frame: 12 weeks ]
    Percentage of closure of the wound

Secondary Outcome Measures :
  1. Wound Trajectory [ Time Frame: 4, 8, 12 weeks ]
    Mean of percent (%) wound size changes at 4 weeks, 8 weeks and 12 weeks

  2. Ulcer Recurrence [ Time Frame: 3 months ]
    Ulcer recurrence out to 3 months for subjects whose wounds heal by conclusion of 12 week visit.

  3. Quality of Life score [ Time Frame: 3 months ]
    Changes in Quality of Life scores and ability to return to previous function/resumption of normal activities

  • Diabetes mellitus (type I or II) that is adequately controlled
  • The ulcer is greater than 4 weeks duration.
  • The largest non-healing wound, if multiple wounds are present, or the single wound to be treated (index ulcer) is a Wagner 1 or 2 DFU (see Appendix for Wagner Classification) that is located on the plantar, medial, or lateral aspect of the foot (including all toe surfaces but not on the heel).
  • Post-debridement, the ulcer size must be between 0.5 - 20 cm2.
  • One of the following assessments was completed to confirm pedal circulation: ankle / brachial index is between 0.7 to 1.2; transcutaneous partial pressure oxygen (TcPO2) > 30 mmHg at the ankle; or toe pressure of >40mm Hg or a doppler waveform consistent with adequate flow in the foot (biphasic or triphasic)
  • Able and willing to provide a voluntary written informed consent.
  • Able and willing to wear an off-loading device or orthopedic shoe
  • Able and willing to attend scheduled follow-up visits and study related exams

Exclusion Criteria:

  • Greater than 30% reduction in wound size during the first two weeks of observation and treatment by the investigator
  • Wagner 3, 4, 5 DFU
  • Gross clinical infection at the study ulcer site including cellulitis and osteomyelitis
  • Wounds that are likely to require dressing changes more frequent than twice weekly (heavy exudates).
  • Known allergy tor sensitivity to Eclipse PRP kit components (calcium chloride, calcium gluconate or acid citrate dextrose solution A (ACDA))
  • Presence of Gangrene
  • Active Charcot's disease as determined by clinical and radiographic examination of a non-diabetic pathophysiology (e.g., rheumatoid, radiation-related, and vasculitis related ulcers)
  • Malignancy at or near the ulcer site
  • Known serum albumin < 2.5 mg/dl, Known renal failure as determined by a Creatinine > 2.5 mg/dl, Plasma Platelet count of less than 100 x 109/L, Hemoglobin of less than 10.5 g/dL
  • Rheumatoid arthritis (and other collagen vascular disease), vasculitis, sickle cell disease, HIV
  • Severe liver disease. Severe liver disease is defined as known history of chronic hepatitis or cirrhosis &/or the following abnormal Liver Function Tests: ALT & AST >35, ALP >120, PT >12 seconds.
  • Presence of additional abnormal lab values obtained within 7 days prior to the Day 0 visit determined to be clinically significant by the investigator including: WBC >13,000/cm3 or < 5, 000 cm3, or electrolytes that are outside the host institution's range of normal.
  • Radiation therapy, chemotherapy, chronic steroid use or immunosuppressive therapy within 30 days of enrollment
