StrataGraft® Skin Tissue as an Alternative to Autografting Full-thickness Complex Skin Defects

July 13, 2021 updated by: Stratatech, a Mallinckrodt Company

Open-label, Controlled, Randomized, Multicenter, Dose Escalation Study Evaluating the Safety, Tolerability, and Efficacy of Single or Multiple Applications of StrataGraft® Skin Tissue as an Alternative to Autografting Full-thickness Complex Skin Defects

About 20 participants will be enrolled in this trial if they have had an accident that damages both the dermal (outside) and epidermal (inside) layers of skin on up to 49% of their body.

This condition is called full-thickness complex skin defects resulting from acute traumatic skin loss.

Participants will be treated with StrataGraft skin tissue to evaluate it's safety and effectiveness for use in treating full-thickness complex skin defects.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The objective of this range-finding study was to assess the safety, tolerability, and efficacy of single or repeated application of StrataGraft skin tissue in full-thickness complex skin defects resulting from acute traumatic skin loss (eg, thermal burns or degloving injuries) requiring surgical excision and autografting.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (ADULT, OLDER_ADULT)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: StrataGraft skin tissue
Biological: StrataGraft Skin Tissue
StrataGraft® skin tissue is provided as a suturable rectangular piece of stratified epithelial tissue composed of a living dermal matrix containing dermal fibroblasts overlaid with human epidermal keratinocytes (NIKS®).
Procedure: Autograft
The current standard of care procedure for the treatment of severe complex skin defects. The procedure involves the removal of a sheet of healthy skin from an uninjured site on the patient and using it to cover the original wound.

What is the study measuring?

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

Time Frame: 3 months
The percentage of the treatment site area initially covered with StrataGraft tissue that requires autograft by three months will be determined.
3 months
