A Phase I, Single-blind, Randomized Study of the Safety and Efficacy of Cellularized Integra® Using Autologous Burn-derived Stem Cells (Integra®-SC)

December 11, 2023 updated by: Marc Jeschke, Hamilton Health Sciences Corporation
Burn injuries are one of the most severe skin injuries and lead to a complex wound healing response. When the skin is wounded, stem cells in the skin must respond fast to help repair the injured tissue. The damaged skin of burn patients contains cells that are still alive and have typical stem cell characteristics. Because stem cells are so important for wound healing, the investigators have combined them with an existing skin substitute, Integra®, to examine the potential wound healing benefits of these stem cells. This is an investigational treatment and a first in-human trial. The purpose of this study is to test the safety of using a patient's own stem cells combined with Integra®, which the investigators call Integra®-Stem Cells (Integra®-SC). The investigators hypothesize that Integra®-SC will result in improved wound healing, better scar quality, and decreased scar formation at one-year post-injury.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety - Number of participants with surgical site infections
Time Frame: Acute hospitalization (1-4 months post admission depending on severity of injury)
The primary outcome of this study is safety. In order to assess the safety of Integra®-SC, surgical site infections that require an additional (unplanned) operation will be recorded as an in-hospital complication.
Acute hospitalization (1-4 months post admission depending on severity of injury)
Safety - Number of participants with non-healing wounds
Time Frame: Acute hospitalization (1-4 months post admission depending on severity of injury)
The primary outcome of this study is safety. In order to assess the safety of Integra®-SC, non-healing wounds that require an additional (unplanned) operation will be recorded as an in-hospital complication.
Acute hospitalization (1-4 months post admission depending on severity of injury)
Safety - Number of patients with poor scarring requiring additional (unplanned) operation
Time Frame: Discharge to to 1 year post-discharge
The primary outcome of this study is safety. In order to assess the safety of Integra®-SC, poor scarring requiring an additional (unplanned) operation will be recorded as a late-onset complication.
Discharge to to 1 year post-discharge
