This is a prospective, randomised, open label, controlled pilot study to evaluate the safety and preliminary effectiveness of the ReCell Autologous Cell Harvesting Device (ReCell) for the management of chronic leg ulcers associated with venous insufficiency. Outcome will be compared between study participants receiving standard care (debridement, compression therapy) and participants receiving ReCell in addition to standard care.

Condition Intervention Phase
Venous Leg Ulcers
Device: Standard Care plus ReCell
Other: Standard Care
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study

Primary Outcome Measures:
  • Wound healing [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    The primary objective of the study is to assess the difference in incidence of ulcer closure (investigator assessed as complete epithelialisation without drainage) between the ReCell group and the control group.

Secondary Outcome Measures:
  • Wounds characterization/Quality of Life [ Time Frame: At each follow-up visit (1, 2, 4, 6, 8, 12, 24, 52 weeks) ] [ Designated as safety issue: No ]
    • Wound area
    • Wound volume
    • Pain
    • Recurrence
    • Health-related Quality of Life

  • Dressing Change [ Time Frame: At each follow-up visit (1, 2, 4, 6, 8, 12, 24, 52 weeks) until healed ] [ Designated as safety issue: No ]
    - Dressing change

Estimated Enrollment: 65
Study Start Date: January 2013
Estimated Study Completion Date: September 2015
Estimated Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Control: Standard Care
The control group will receive standard care (debridement, cleansing) and Profore® multi-layer compression therapy (replacing the wound contact layer with Telfa™ Clear).
Other: Standard Care
Experimental: ReCell
The ReCell group will receive ReCell in addition to standard care (debridement, cleansing) and Profore® multi-layer compression therapy (replacing the wound contact layer with Telfa Clear).
Device: Standard Care plus ReCell
