Continued Access to the Recell® Device for Treatment of Acute Burn Injuries

Study Overview
=================
Brief Summary
-----------------
The overall purpose of this continued access study is to allow ongoing treatment of subjects at selected investigational sites while the marketing application for the ReCell® Autologous Cell Harvesting Device is under FDA review. This is a prospective, multicenter, single-arm observational study to evaluate the safety and clinical performance of the ReCell® device when used as an adjunct to meshed autografts in patients with acute thermal burn injuries requiring skin grafting for closure.

Detailed Description
-----------------
Patients 5 years or older with a total body surface area (TBSA) thermal burn injury between 5 and 50% (inclusive) who require autografting will be considered for participation in this study. RES (Regenerative Epithelial Suspension) derived from the use of the ReCell® device will be applied over skin grafts meshed more widely than conventional autografting. Healing, scar outcomes, pain and treatment-related adverse events will be evaluated at follow-up visits. Data concerning the clinical performance and safety of the ReCell device will be collected. Safety will be evaluated in terms of treatment and serious related adverse events. Each subject will participate in up to 7 total visits (treatment visit and 6 follow-up study visits) over a period of 24 weeks. Up to 60 subjects will be enrolled and treated within this study at up to 15 institutions. It is anticipated that enrollment will continue until PMA approval. Subject follow-up will continue until the last enrolled subject completes the 24-week visit.

* Device: ReCell® Autologous Cell Harvesting Device


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: The subject requires skin grafting as a result of an acute thermal burn injury (i.e., injuries caused by exposure of the skin to fire/flames, excessive heat, hot steam or water). The area of total burn injury is 5-50% TBSA inclusive. Area(s) requiring skin grafting at least 320 square centimeters. The subject is at least 5 years of age. The subject (or family, for those under 18 years of age) is willing and able to complete all follow-up evaluations required by the study protocol. The subject is to abstain from any other treatment of the wound(s) for the duration of the study unless medically necessary. The subject agrees to abstain from enrollment in any other interventional clinical trial for the duration of the study. The subject and/or guardian are able to read and understand instructions and give informed, voluntary, written consent. Exclusion Criteria: The subject's burn injuries were caused by chemicals, electricity, and/or radioactive substances. The subject is unable to follow the protocol. The subject has other concurrent conditions that in the opinion of the investigator may compromise patient safety or study objectives. The subject has a known hypersensitivity to trypsin or compound sodium lactate for irrigation (Hartmann's) solution. Pregnant or lactating women.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Wound Healing | Treatment area will be evaluated via direct visualization by the treating investigator. Complete wound closure is defined as ≥95 to100% re-epithelialization without drainage by week 8. | Confirmed by week 8, at two consecutive study visits at least 2 weeks apart up to 24 Weeks (e.g., at week 4 and week 8, or if a visit was missed, week 4 and week 12) |
