Multicenter Single-arm Trial to Investigate Clinical Outcomes When Cohealyx™ is Used for Full Thickness Wounds (Cohealyx I)

March 10, 2026 updated by: Avita Medical

A Prospective Multicenter Single-arm Clinical Study to Investigate Clinical Outcomes When Cohealyx™ is Used for the Management of Full Thickness Wounds Post-surgical Excision

The goal of this study is to look at clinical outcomes when Cohealyx Collagen Matrix is used to treat full thickness wounds after surgical excision in patients that require a skin graft to heal their wounds. The main question it aims to answer is how long does it take for Cohealyx to support definitive closure.

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

This is a prospective single-arm post-market multicenter study to evaluate clinical outcomes of Cohealyx when used to manage full thickness wounds post-surgical excision. A systematic literature review and meta-analysis were conducted to establish a performance goal for the primary effectiveness endpoint (time to autografting).

Patients with a full thickness wound where autografting is clinically indicated will be considered for participation in this study. Patients will undergo a staged surgical procedure for wound closure. In the first surgery, Cohealyx will be applied to the surgically excised wound bed within 5-days post-injury.

Following placement of Cohealyx, investigators will evaluate the wound every 3 days. Once Cohealyx has successfully integrated into the wound bed, as indicated by a robust vascularized tissue bed, the wound bed will be prepared and autografted per the investigative site's standard of care.

The study area will be evaluated with respect to Cohealyx integration, time to autografting, autograft take, healing, and safety-related adverse events.

Post-autografting, subjects will be followed for 6.5 months. Treatment-related and serious adverse events will be reported through the duration of the study. At all visits, subjects' study treatment areas as well as any donor sites dressed in PermeaDerm will be documented using digital photography.

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
