Efficacy of a Photosynthetic Dermal Matrix for the Treatment of Full-Thickness Skin Wounds

Overview

The goal of this clinical trial is to evaluate whether the incorporation of photosynthetic microalgae into scaffolds for dermal regeneration improves healing outcomes in adult patients with acute and cronic full-thickness skin wounds. The primary objectives are to determine whether the use of photosynthetic scaffolds enhances wound granulation and reduces infection rates compared to standard dermal regeneration scaffolds. Additionally, the quality of the regenerated skin will be assessed and compared between treatment types. Participants will: * Receive treatment with either standard dermal regeneration scaffolds or identical scaffolds containing photosynthetic microalgae. These treatments will be applied either to randomly assigned areas of the same wound or to different wounds on the same patient. * Undergo regular follow-up assessments to monitor wound healing progress, infection rates, graft integration, and the qualiy of the regenerated skin. * Complete self-assessment questionnaires regarding their experience and perceived outcomes.

Chronic and acute skin wounds are a significant and growing public health concern, affecting millions of people worldwide and placing a substantial burden on healthcare systems. These wounds, often resulting from underlying conditions such as diabetes, vascular disease, or trauma, can take months or even years to heal, severely impacting patients' quality of life. As global populations age and chronic diseases become more prevalent, the need for more effective wound care solutions is becoming increasingly urgent. One area of innovation in wound management involves the use of advanced biomaterials that support the body's natural regenerative processes. Dermal regeneration matrices (DRMs) are among the most promising of these technologies, providing a structural scaffold to facilitate tissue repair. However, a major limitation of current DRMs is the poor oxygenation at the wound site during the initial phases of healing-an issue that can delay granulation tissue formation, increase infection risk, and ultimately impair outcomes. To address this challenge, a novel approach has been developed that incorporates photosynthetic microalgae into the scaffold itself. These microorganisms are capable of producing oxygen when exposed to light, offering a potential means of delivering localized oxygen directly to the wound bed. This photosynthetic dermal regeneration matrix (PDRM) is designed to create a more favorable microenvironment for tissue regeneration by enhancing local oxygen availability in situ. The present study is a randomized, controlled clinical trial designed to evaluate the safety and efficacy of PDRMs in adult patients with acute and cronic full-thickness skin wounds. Outcomes in wounds treated with PDRMs will be compared to those treated with conventional DRMs. Key endpoints include wound closure, granulation tissue formation, infection rates, graft integration, and overall skin regeneration quality. If effective, this approach could represent a significant advance in wound care, offering accelerated healing, reduced complications, and improved patient-reported outcomes. The strategy may also broaden the applicability of regenerative therapies in diverse clinical settings by enhancing the functionality of existing biomaterials.
