An interventional study of Wound debridement and Wound closure matrix application in Diabetic Foot, Ulcer Foot and Wound Heal, sponsored by Polymedics Innovations Inc.. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2023-08-28.

Supra SDRM® is FDA-cleared as a dressing for treating partial and full-thickness wounds. It is a dermal substitute that provides a barrier and an ECM-like structure to help accelerate wound healing. SUPRA SDRM® has 510k approval for partial and full-thickness wounds and has shown promising results in preliminary animal studies. The purpose of this clinical evaluation is to collect and compare outcomes data from patients with UT 1A diabetic foot ulcers treated with a commercially available dermal substitute, Supra SDRM®, as compared to an advanced standard of care (Fibracol Plus). Patient outcomes, including time to heal, healing by 12 weeks, direct costs, and infection rate, will be compared at the end of the study.
Chronic wounds are those that fail to proceed through the normal phases of wound healing. They pose a high risk for infection and risk complications resulting in amputation. A plethora of wound treatment modalities are commercially available to help improve patient outcomes. However, even when combined with a good standard of care practices and wound dressings, they may not be sufficient to promote timely wound closure. Cellular and/or tissue- based products (CTPs) may provide a healing advantage over traditional dressings. CTPs are derived from human (allograft), animal (xenograft), or synthetic materials or a combination thereof. CTPs can help encourage tissue repair or regeneration by providing scaffolds and the cells necessary to stimulate wound healing. Synthetic products may provide advantages over human or other animal sourced products because they are natural, non-biologic, avoid complications due to risk of disease transmission, and possess less immunologic potential.
The fully synthetic skin substitute evaluated in this study is SUPRA SDRM® Synthetic Biodegradable Matrix Wound Dressing (Polymedics Innovations Inc.; Woodstock,GA). The device is a novel synthetic, guided wound closure matrix, built as a bimodal foam membrane structure for the management of chronic wounds. It combines the benefits of a microporous structure that builds a protective barrier allowing the wound to heal and additional large pores which were created to enable ingrowth of blood vessels. This microenvironment initially provides a seal against contamination and modulates inflammation in wound bed. Subsequently, it supports cellular processes required for tissue repair and wound healing.
In this parallel randomized clinical trial, patients with diabetic foot ulcers grade UT 1A will receive either standard of care plus SUPRA SDRM or a collagen dressing (Fibracol Plus) weekly after wound debridement. Primary outcomes will be time to achieve wound healing, and the proportion of patients achieving healing by 12 weeks. Secondary outcomes will include the direct costs of treatment and the proportion of patients who developed infections during the trial.

Exclusion Criteria:
The subject will receive wound standard of care that will include Supra SDRM as an active synthetic wound closure matrix, covered with a non-adherent dressing plus an appropriate outer dressing to maintain moisture balance, then wrapped with stretch gauze and self-adherent wrap. Supra SDRM will be applied weekly, and the exterior dressings will be redressed as necessary. Supra SDRM is FDA-cleared (K090160, K170213) for the management of partial and full-thickness wounds, such as pressure sores, leg ulcers, diabetic ulcers, and surgical wounds. It is commercialized as a single dermal substitute matrix for wound management. No preparation of SUPRA SDRM matrix is necessary. When applied to the wound SUPRA SDRM adheres well to the wound bed without the need for direct fixation. SUPRA SDRM becomes translucent after the application allowing healthcare professionals to easily assess the wound healing. SUPRA SDRM® is available in multiple sizes and can be trimmed to meet the patient's needs.
Procedure: Wound debridement · Device: Wound closure matrix application
The subject will receive wound standard of care that will include Fibracol Plus collagen dressing as an active synthetic wound closure matrix, covered with a non-adherent dressing plus an appropriate outer dressing to maintain moisture balance, then wrapped with stretch gauze and self-adherent wrap. Fibracol Plus collagen dressing will be applied weekly, and the exterior dressings will be redressed as necessary. FIBRACOL™ Plus Collagen Wound Dressing with Alginate dressing contains more than just pure collagen. It's a soft, absorbent, and conformable wound dressing, composed of 90% collagen and 10% calcium alginate. In the presence of wound fluid, FIBRACOL™ Plus Dressing helps maintain a physiologically moist microenvironment at the wound surface. This environment supports granulation tissue formation, epithelialization and rapid wound healing.
Procedure: Wound debridement · Device: Wound closure matrix application
The study's wounds will be mechanically debrided before the experimental or active comparator devices are applied. Debridation will be performed by a trained clinician using a curette. Necrotic tissue and slough will be removed during this procedure.
After wound debridement, the patients will receive the application of a wound closure matrix as dictated by their randomization allocation.
