August 3, 2026 updated by: Veronique Moulin, CHU de Quebec-Universite Laval

SASS 2 : Self Assembled Skin Substitute for the Autologous Treatment of Severe Burn Wounds in Acute Stage of Burn Trauma.

This clinical trial is designed to assess the safety, effectiveness and benefits of Self Assembled Skin Substitute SASS grafts as a permanent skin replacement for the treatment of full-thickness burn wounds that require permanent coverage where the availability of donor sites is limited.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

  • Deep second degree burns or third degree burns over 50% TBSA (Total body surface area) at time of recruitment or as determined by the surgeon;
  • Limited availability of donor sites for autografts;
  • Consent obtained by the participant or by the appropriate representative in case of inapt prospective participants or minors.

Exclusion Criteria:

  • Skin grafting needed only on the face, hands, feet, ears or genital area;
  • Connective tissue diseases;
  • Hypersensitivity to bovine proteins;
  • Coagulation disorders prior being burned;

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: Treatment (SASS)
Phase A: All patients will receive both Self assembled skin substitute (SASS) and Split-thickness autograft (paired samples sites A+ B). // Phase B: All patients will receive Self assembled skin subsitute (SASS)
Biological: Self assembled skin substitute (SASS)
All patients in Phase B will receive Self assembled skin substitute (SASS)

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

Percentage of graft take site A vs site B (Phase A 17 patients)
Time Frame: < 1 month
Clinical assessment; Image analysis

Time Frame: < 1 month
Clinical assessment
< 1 month

Secondary Outcome Measures

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2015

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
