This study is designed to evaluate whether the Miro3D Wound Matrix, when used in addition to standard of care, improves healing outcomes in patients with chronic diabetic foot ulcers. Diabetic foot ulcers are a common and serious complication of diabetes and may be difficult to heal despite appropriate treatment. Standard of care typically includes regular wound cleaning, debridement (removal of dead tissue), offloading (reducing pressure on the wound), and moisture-balancing dressings. However, some wounds fail to heal with standard treatment alone. Miro3D Wound Matrix is a three-dimensional, acellular scaffold derived from porcine tissue that is intended to support wound healing. This study will compare outcomes in patients treated with Miro3D plus standard of care versus standard of care alone. Approximately 180 adult subjects with non-healing diabetic foot ulcers will be enrolled at multiple clinical sites in the United States. After a two-week screening period, eligible participants will be randomly assigned to receive either Miro3D in addition to standard of care or standard of care alone. Subjects will be followed for up to 12 weeks with weekly clinic visits. The primary objective of the study is to determine whether treatment with Miro3D increases the rate of complete wound closure and improves reduction in wound size compared to standard of care alone. Safety will also be evaluated by monitoring adverse events throughout the study.
This is a prospective, multicenter, open-label, randomized controlled trial designed to evaluate the safety and effectiveness of the Miro3D Wound Matrix in the treatment of chronic, non-healing diabetic foot ulcers (DFUs). Diabetic foot ulcers represent a significant clinical and economic burden and are associated with increased risk of infection, hospitalization, and amputation. Despite adherence to standard of care (SOC), including offloading, debridement, infection control, and moisture management, a substantial proportion of DFUs fail to achieve complete healing. This study aims to assess whether adjunctive treatment with Miro3D Wound Matrix can improve healing outcomes compared to SOC alone. Miro3D Wound Matrix is a sterile, acellular, three-dimensional scaffold derived from porcine liver tissue. The matrix is designed to provide a structural environment that supports tissue regeneration and wound healing. The product is applied topically to the wound following appropriate wound bed preparation. Approximately 180 adult subjects with Wagner Grade 1 or 2 diabetic foot ulcers will be enrolled across up to 20 clinical sites in the United States. Subjects must have ulcers present for at least 4 weeks but less than 12 months and must demonstrate less than 25% reduction in wound area during a two-week screening period under standard of care. Following screening, eligible subjects will be randomized in a 1:1 ratio to one of two treatment arms: treatment with Miro3D Wound Matrix in addition to standard of care, or standard of care alone. Standard of care will include sharp debridement, offloading using a protocol-defined device, and appropriate moisture-retentive dressings. Subjects will be evaluated at weekly intervals for up to 12 weeks. At each visit, assessments will include wound measurement, photographic documentation, infection status, pain assessment using the Numeric Pain Rating Scale (NPRS), and monitoring of adverse events. At select sites, additional exploratory imaging assessments may be performed, including near-infrared tissue oxygenation and fluorescence imaging. The primary endpoints of the study are complete wound closure at 12 weeks, defined as full re-epithelialization without drainage or need for dressing, with closure confirmed at a single healing confirmation visit conducted two weeks after complete closure is initially documented, and percentage area reduction of the target ulcer over the study period. Secondary endpoints include change in pain associated with the ulcer and the incidence and frequency of adverse events. Exploratory endpoints will assess spatial and temporal changes in tissue oxygenation and fluorescence imaging characteristics at technology-enabled sites. The study will use a Bayesian adaptive statistical framework, incorporating prior information and observed data to estimate treatment effects. Interim analyses may be conducted to evaluate efficacy, safety, and sample size assumptions. This study is intended to generate clinical evidence supporting the use of Miro3D Wound Matrix as an adjunctive therapy for improving healing outcomes in patients with chronic diabetic foot ulcers.

Proportion of Participants Achieving Complete Wound Closure of the Target Diabetic Foot Ulcer at 12 Weeks
Complete wound closure is defined as full re-epithelialization of the target ulcer without drainage or need for dressing, with closure confirmed at a single healing confirmation visit conducted approximately two weeks after complete closure is initially documented.
Time frame: Up to 12 weeks
Mean Percentage Reduction in Target Ulcer Surface Area From Baseline to 12 Weeks
Percentage area reduction (PAR) is defined as the percent change in surface area of the target ulcer from baseline, as measured by digital planimetry.
Time frame: Baseline through 12 weeks
Mean Change From Baseline in Ulcer-Associated Pain Score Assessed by Numeric Pain Rating Scale (NPRS)
Ulcer-associated pain will be assessed using the Numeric Pain Rating Scale (NPRS), a patient-reported scale ranging from 0 (no pain) to 10 (worst possible pain).
Time frame: Baseline through 12 weeks
Number of Participants Experiencing Treatment-Emergent Adverse Events
Treatment-emergent adverse events will be collected and coded throughout the study period and summarized by treatment group.
Time frame: Up to 12 weeks
