The purpose of this clinical trial is to perform a limited pilot study to determine the feasibility of DermGEN in the treatment of non-healing diabetic foot ulcers (DFU). This will be a one-arm prospective study. It is hypothesized that DermGEN treatment will result in positive healing outcomes with no significant adverse effects.

Primary Outcome Measures:
  • Mean and Median Wound Size [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion with Complete Healing [ Time Frame: 12 and 16 weeks ] [ Designated as safety issue: No ]
    Complete healing is defined as 100% epithelialization without drainage

    Complete healing is defined as 100% epithelialization without drainage

  • Incidence of Recurrence [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Incidence of Adverse Events [ Time Frame: 16 weeks ] [ Designated as safety issue: Yes ]
  • Wound Characterization [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Mean and Median Wound Size [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Percent Change in Wound Area [ Time Frame: 4 Weeks ] [ Designated as safety issue: No ]

Detailed Description:
This will be a one-arm prospective study with control comparisons made to historical data for standard of care treatment of DFU's (debridement, sterile moist bandages, off-loading of the foot) obtained within the Multi-Disciplinary Leg Ulcer Clinic (MDLUC) at the QEII Hospital. This study in Halifax will be mirrored in one other participating health care center in Toronto, Ontario, Canada with each center enrolling 5-10 patients for a total of 15-20 patients.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient with documented stable Type I or II diabetes (HbA1C confirmation every 4 months)
  • Patient's ulcer is present for a minimum of 2 weeks under Investigator's care
  • Study ulcer has healed <50% in size during 2 weeks leading up to enrollment
  • Study ulcer is on plantar surface of the foot
  • Ulcer ≥1 cm2 at Day 0 of study*
  • Ulcer extends through dermis and into subcutaneous tissue but without exposure of muscle, tendon, bone or joint capsule
  • Ulcer is free of necrotic debris and clinical infection, and is comprised of healthy vascular tissue suitable for skin grafting 2 weeks after initial presentation
  • Patient has adequate circulation to the foot as evidenced by palpable pulse
  • Ankle-Brachial Index (ABI) and Toe-Brachial Index (TBI) of ≥0.7? (mild to moderate obstruction)
  • Female patients are not pregnant at time of, or during study
  • Patient and caregiver ready and willing to participate and comply with follow-up regime
  • Patient or legal representative has read and signed the Institutional Ethics Review Board approved informed consent form

    • - ulcer usually presents as around 1 cm2 but is greater after debridement

Exclusion Criteria:

  • Evidence of gangrene on affected foot
  • Ulcer is over Charcot deformity (fractures or dislocation)
  • Ulcer is non-diabetic in etiology
  • Ulcer has tunnels or sinus tracts that cannot be completely debrided
  • Patient's HgA1C < 12
  • Medical condition(s) that in the Investigator's opinion make the patient inappropriate for study
  • Patient has/had malignant disease not in remission for 5 years or more
  • Patient has acute or chronic Hepatitis, Cirrhosis, has serum albumin <2.0 gms/dL, or has alkaline phosphatase or LDH at twice the normal upper limit
  • Patient receiving oral or parenteral corticosteroids, immunosuppression or cytotoxic agents, or is anticipated to require such agents during study
  • Patient received radiation therapy within 30 days of Day 0 of study
  • Patient has AIDS or is infected with HIV
  • Patient has participated in another study using investigational drug(s) or device within the previous 30 days
  • Obvious clinical signs and symptoms of cellulitis and osteomyelitis
  • Patient has any other conditions which seriously compromises their ability to complete the study
  • Patient has known allergies to antibiotics such as Penicillin and Streptomycin
  • Patient has history of bleeding disorder
  • Patient received elective osseous procedures to study foot with 30 days prior to screening visit
