Pilot Trial for WounDx™ Clinical Decision Support Tool

July 29, 2026 updated by: Henry M. Jackson Foundation for the Advancement of Military Medicine

SC2i-WounDx-001-WounDx™ Pilot Trial: Proof of Concept Feasibility for the Clinical Operations of WounDx™ in Aiding Clinicians Identify Wounds That Are Ready For Surgical Closure

The purpose of this research is to evaluate the overall use of the WounDx medical device in a clinical setting, such as a hospital. The WounDx device is experimental and not yet approved by the United States Food and Drug Administration (FDA). WounDx uses information about a patient's wound to generate a report that a surgeon may use to help determine when to close or not close the wound. The final decision to close the wound remains with the surgeon. The results from this pilot trial will inform a larger pivotal trial.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Determining if a large, traumatic extremity wound is ready for successful delayed closure remains a challenge, as approximately 23%-25% of these wounds fail to heal after delayed closure is attempted, even when treated with aggressive surgical interventions, including debridement every 2-3 days. This pilot trial uses WounDx™, a device that aids clinicians in identifying extremity wounds that are likely to heal after surgical closure. The device is a Clinical Decision Support Tool (CDST) and consists of two main components: an immunoassay to obtain the expression of inflammatory biomarkers and, together with clinical data input, an interpretative algorithm. The purpose of the device is to identify wounds likely to proceed through normal phases of wound healing and, as a result, provide the clinician with a wound-specific prediction that an open traumatic extremity wound will heal successfully and remain closed if delayed closure is performed. The pilot trial serves as a proof of concept (POC) trial and establishes the overall feasibility of clinical operations (including recruitment, randomization, implementation of the intervention, and data collection). Trial enrollment is planned only for adults (≥18 to ≤65 years) with at least one traumatic extremity wound ≥75cm 2 , being treated with Negative Wound Pressure Therapy (NPWT), and delayed primary closure including split thickness skin grafting and rotational or free flaps. Local and systemic inflammatory biomarker expression will be assessed in wound effluent samples collected during subject treatment. These results will be input with other associated clinical data to WounDx™ to allow the device to provide a report including a recommendation on whether a specific wound should be closed within 48-72h of the previous debridement surgery, which is consistent with the current clinical practice guidelines. This pilot trial will inform the conduct of a larger, pivotal clinical trial to evaluate the safety and efficacy of WounDx™ in aiding clinicians identify traumatic extremity wounds ready for surgical closure.

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.
