Outcome Measures

Primary Outcomes (1)

  • To use the novel technology of microarrays to identify and characterize the molecular mechanisms through which Apligraf promotes healing of venous leg ulcers.

    2 weeks

Secondary Outcomes (5)

  • Determine how venous leg ulcer (VLU) wounds transition from chronic to acute wound healing

    2 weeks

  • Examine how Apligraf rescues deficiencies of chronic wounds (VLU) and promotes transition from chronic to acute wound

    2 weeks

  • Determine growth factors induced by Apligraf in the wound

    2 weeks

  • Determine growth factors suppressed by Apligraf in the wound

    2 weeks

  • Safety endpoints assessed by monitoring adverse events

    5 months

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject has non-infected partial or full-thickness venous leg ulcer for a duration of four weeks or greater which has not adequately responded to conventional therapy
  • Stage II or III ulcer as defined by the IAET/WOCN ulcer classification guide listed in Appendix IV.
  • Subject is female and 18 years of age or older.
  • Subject with venous leg ulcer (target ulcer) between 5 - 40 cm2 in size.
  • Sexually active females must be practicing a medically proven form of contraception during the course of the study period.
  • Subject or legal guardian must have read, understood and signed an institutional review board (IRB) approved Informed Consent Form.
  • Subject and/or legal guardian must be able and willing to follow study procedures and instructions.

You may not qualify if:

  • Subject whose target ulcer has healed 60% or greater in area from post debridement (if applicable) Baseline Screen (Visit 1) to post debridement Day 0 (Visit 2) as determined by wound tracings.
  • Subjects who are being treated with VAC® (Vacuum Assisted Closure™) Therapy.
  • Subject has arterial disease as determined by an Ankle Brachial Index (ABI ) of \<0.65.
  • Subject with any systemic condition like uncontrolled diabetes mellitus (glycosylated HbA1C \> 12%), cancer (biopsy confirmed active malignancy), positive HIV test, or any disorder(s) that may compromise wound healing.
  • Subjects who are currently receiving, or have received at any time within one month prior to entry into the study, corticosteroids (\>15 mg/day), immunosuppressive agents, radiation therapy, hemodialysis or chemotherapy. Anticipated use of the above agents will exclude subjects from entry into the study.
  • Clinical vasculitis, severe rheumatoid arthritis, and other collagen vascular diseases.
  • Signs and symptoms of cellulitis or osteomyelitis.
  • Necrotic or avascular ulcer beds.
  • Venous leg ulcer with exposed bone, tendon or fascia.
  • Subject with the presence of recent infections in the area intended for treatment.
  • Known hypersensitivity to bovine collagen or to the components of the Apligraf agarose shipping medium.
  • Subject who is lactating or pregnant (hCG positive as determined by lab testing).
  • Subject with liver (ALT/SGPT, ALP, AST/SGOT, bilirubin, Albumin, total protein, LDH) and/or renal function (BUN and creatinine) tests greater than 2 x upper limit of normal (ULN) or Albumin \< 2.5 mg/dL.
  • Subject enrolled in any wound or investigational device study for any disease within the past four weeks.
  • Subject previously treated at target site with Apligraf, Dermagraft or any other cell therapy at the target site.
  • +2 more criteria
