OASIS Wound Matrix (Oasis) will be applied to wounds, with sequential biopsy of healing wounds to explore the mechanism of action.

Condition Intervention Phase
Diabetic Foot Ulcers (DFU)
Venous Stasis Ulcers (VSU)
Device: OASIS Wound Matrix
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Official Title: Case Study Documentation of Subjects With Either Diabetic Foot Ulcers or Venous Stasis Ulcers Being Treated With OASIS

Primary Outcome Measures:
  • Decrease in Wound Area From Baseline After 12 Weeks of Treatment or Until Wound Closure, Whichever Occurred First. [ Time Frame: Baseline and weekly up to 12 weeks ] [ Designated as safety issue: No ]

    Wound measurements were made weekly, spaced 7 +/- 1 day apart, up to 12 weeks or until the wound healed, whichever occurred first.

    The final measurement taken was subtracted from the baseline to assess the decrease in wound area after treatment.

    Final calculation is mean baseline measurement minus final measurement at 12 weeks (or when wound healed, whichever occurred first)

  • Percent Wounds Closed [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]

    Wound healing was assessed weekly, spaced 7 +/- 1 day apart, up to 12 weeks or until the wound healed, whichever occurred first.

    The outcome value was based on the percent of wounds which were closed at the end of the study (at 12 weeks). The percent wounds closed were calculated for each wound type: Diabetic Foot Ulcers (DFU) and Venous Stasis Ulcers (VSU).
