Trial Outcomes & Findings for ReCell® Combined With Meshed Skin Graft in the Treatment of Acute Burn Injuries (NCT NCT02380612)

NCT ID: NCT02380612

Last Updated: 2025-01-07

Results Overview

Complete wound closure is defined as skin re-epithelialization without drainage, confirmed at two consecutive study visits at least 2 weeks apart by direct visualization by a qualified clinician blinded to treatment assignment. The incidence of complete wound closure is hypothesized to be non-inferior for RECELL-treated areas as compared to control areas.

Measure
Experimental: All Participants (Within Patient Control)
Every subject received both interventions (RECELL and CONTROL) such that each subject served as their own control. Each subject's study treatment area (burn injury) was divided into Area A and Area B before thee areas (A and B) were randomly assigned to receive CONTROL (grafting consistent with the pre-identified graft plan) or RECELL (RECELL-generated cell suspension applied over a graft more widely meshed than identified in the pre-specified graft plan).

All subjects receive both ReCell treatment and autograft (Area A and Area B). Each subject serves as their own control. Wound regions were randomly assigned to receive an autograft consistent with the investigator's pre-identified graft plan (Control) or to receive application of the ReCell-generated cell suspension over an autograft more widely meshed than identified in the investigator's pre-specified graft plan (ReCell-treated).

PRIMARY outcome

Timeframe: Prior to or at 8 weeks

Population: Per Protocol Population

Complete wound closure is defined as skin re-epithelialization without drainage, confirmed at two consecutive study visits at least 2 weeks apart by direct visualization by a qualified clinician blinded to treatment assignment. The incidence of complete wound closure is hypothesized to be non-inferior for RECELL-treated areas as compared to control areas.

PRIMARY outcome

Timeframe: Prior to or at 8 weeks

Population: Intent-to-Treat Population (primary analysis)

For this second co-primary endpoint, it is hypothesized that the expansion ratio associated with the RECELL treatment area will be superior to that of the control, i.e. less donor skin will be required for RECELL-treated areas compared with the control areas.

The observer component of the Patient and Observer Scar Assessment Scale (POSAS) questionnaire required the blinded evaluator to provide an overall opinion of the treatment area compared to normal skin, scored from 1 (normal skin) to 10 (worst imaginable scar).
