WounDx device to help guide delayed closure of large traumatic limb wounds

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

Not applicable Interventional Henry M. Jackson Foundation for the Advancement of Military Medicine · NCT06921707

This pilot tests whether the WounDx device can help surgeons decide when delayed closure will successfully heal large traumatic extremity wounds in adults.

What this trial studies

The WounDx device combines a wound immunoassay for inflammatory biomarkers with a clinical-data algorithm to generate a wound-specific report that surgeons can use to guide timing of delayed closure. In this pilot interventional trial, adults with traumatic extremity wounds ≥75 cm2 treated with negative pressure wound therapy and planned delayed primary closure are assigned to WounDx-guided care or standard of care. The device report is provided to the surgeon while the final decision to close remains with the treating clinician, and clinical outcomes plus feasibility metrics (recruitment, randomization, intervention delivery, and data collection) are recorded. Results from this proof-of-concept pilot will inform the design of a larger pivotal trial.

Who should consider this trial

Good fit: Adults aged 18–65 with at least one traumatic extremity wound of ≥75 cm2 being treated with negative pressure wound therapy and planned delayed primary closure (including grafts or flaps) are the ideal candidates.

Not a fit: People with insulin-dependent diabetes, peripheral vascular disease, connective tissue disorders, significant immunosuppression, pregnant people, or prisoners are excluded and would not be expected to benefit from this pilot.

Why it matters

Potential benefit: If successful, WounDx could help surgeons reduce failed delayed closures by providing a wound-specific prediction of healing readiness.

How similar studies have performed: Biomarker-driven clinical decision support for timing wound closure is an emerging approach with limited published clinical evidence, so this pilot is largely a proof-of-concept.
