Standard Treatment Associated With Phage Therapy Versus Placebo for Diabetic Foot Ulcers Infected by S. Aureus

The primary objective of this study is to compare the efficacy of standard treatment associated with a topical anti-staphylococcal bacteriophage cocktail versus standard treatment plus placebo for diabetic foot ulcers monoinfected by methicillin-resistant or susceptible S. aureus (MRSA or MSSA) as measured by the relative reduction in wound surface area (%) at 12 weeks.

Diabetic Foot Ulcer (DFU) Biofilm Infection and Recurrence

This work is based on DFU patients, seeks to conduct a fully powered clinical study testing i) If DFU with a history of biofilm infection closes with deficient barrier function. ii) whether such functionally deficient wound closure, manifested as high TEWL, is associated with greater wound recurrence. The primary parent study will also address molecular mechanisms implicated in biofilm-induced loss of skin epithelial barrier integrity in DFU patients.

Thermographic Camera Validation for Diabetic Foot Assessment (HIK-DM-2026)

This cross-sectional observational study validates the concordance of a low-cost thermographic camera (HIKMICRO Mini2 V2, \~200 Euro) against a professional clinical standard (HIKMICRO M60) for diabetic foot assessment. Both cameras simultaneously capture plantar thermographic images from 130 participants with diabetes mellitus. Maximum contralateral thermal asymmetry (Delta T\_max) across 6 plantar regions of interest (ROIs) is the primary endpoint, analyzed by intraclass correlation coefficient (ICC) and Bland-Altman method.

A multicenter, prospective, controlled clinical trial evaluating the efficacy of a single layer placental-based allograft and standard of care in the management of nonhealing diabetic foot ulcers.

Early Percutaneous Transluminal Angioplasty in Diabetic Foot Syndrome (PTA-DFS)

The planned study is a Randomized Controlled Monocentric Trial, which will provide evidence on whether early angiography in percutaneous transluminal angioplasty (PTA) readiness ("immediate" treatment, within 48h) has advantages over the "standard of care", i.e., an elective procedure ("elective PTA") for the treatment of diabetic foot ulcer (DFU). The primary study endpoint is to investigate the impact of the "early PTA" within 48 hours on wound-healing assessed by wound area changes after PTA using a 3D-camera with artificial intelligence (AI)-based wound-analysis-system. The secondary endpoint is the effect of early PTA on the combined occurrence of major adverse limb (MALE) and cardiac events (MACE) over 12 months post-angioplasty using time-to-event analysis. Data will be collected at baseline, 24 hours, 1, 2, 3, 6, and 12 months after PTA. Diabetic kidney disease, distal symmetric polyneuropathy, retinopathy, cardiomyopathy, laboratory analyses, clinical scores, AI-based fundus photography, echocardiography, duplex sonography, and pulse oscillography will be assessed. Explanatory variables for wound healing are wound microbiome changes using whole-genome sequencing and oxygen saturation of the wound environment measured using near-infrared spectroscopy. Altered microbiome composition in ulcers can lead to severe local and systemic infections and complications, including major amputations. Nevertheless, the specific significance of the wound microbiome composition in chronic ischaemic ulcers in type 2 diabetes and the impact of PTA on the wound microbiome in type 2 diabetes is unclear. The exact timing for treating peripheral arterial disease (PAD) by revascularization in DFU after initial diagnosis is unknown and has yet to be fully understood.

Non-healing Diabetic Foot Ulcers Treated With Standard Care With or Without BR-AM

This trial is a multicenter, randomized, controlled study designed to evaluate the safety and efficacy of BioREtain® Amniotic Membrane (BR-AM) plus standard of care versus standard of care only in the treatment of diabetic foot ulcers. The trial design will control potential variables that may affect the outcome between the treatment group and the control group by standardizing the requirements for debridement, wound dressings, and offloading. Weekly subject visits will help monitor compliance in wound care and off-loading, as well as to document when wound closure is achieved. The study will also implement the use of an electronic imaging and measurement device using a standardized protocol to ensure the measuring of the wound surface area and volume is accurate, highly reproducible, and minimally variable. There will also be a crossover treatment phase for those patients that were relegated to standard care only. After their 12-week standard of care treatment phase and for only those subjects that did not achieve complete wound closure, will be allowed to crossover for an additional 12 weeks of treatment with the BR-AM product following the protocol and procedures set forth within this document.

DFC 004 Biomarkers for Active Diabetic Foot Ulcers

This study is a platform study designed to efficiently test multiple biomarkers to identify diabetic foot ulcers (DFUs) with a higher potential for healing versus not healing that ultimately could be applied at the point of care to drive personalized management decisions, and to better inform clinical trials of wound healing interventions

Effectiveness of Remote Foot Temperature Monitoring

Diabetic foot ulcers are common, debilitating, and costly complications of diabetes, disproportionately impacting Black and rural Veterans. Forty percent of individuals have an ulcer recurrence within a year of ulcer healing and 65% within 5 years. Monitoring plantar foot temperatures is one of the few interventions that reduces the risk of ulcer recurrence. Despite the evidence, adoption has been poor because the original procedures, including the use of handheld thermometers, were burdensome and time-consuming. Podimetrics, a private company, has developed a temperature monitoring system involving a "smart" mat that can wirelessly transmit data and a remote monitoring team that works with VA providers to assist with triage and monitoring. This care model has incredible promise, but has been untested in VA. The investigators propose to conduct a randomized trial to evaluate effectiveness of remote temperature monitoring as well as costs. Additionally, the investigators will evaluate the implementation process, including barriers and facilitators to use among key stakeholders.

Immune Cells in Diabetic Chronic Foot Ulcers

The goal of this observational study is to learn about the role of immune cells in patients with diabetes and chronic foot ulcers. Researchers will compare blood and tissue samples of patients with diabetes and a foot ulcer that is healing or healed compared to those diabetic patients where the foot ulcers is not healing (chronic ulcer).

Trial Assessing the Efficacy of Human Placental Membrane Products and Standard of Care Versus Standard of Care Alone in the Management of Nonhealing Diabetic Foot Ulcers and Venous Leg Ulcers

The purpose of this study is to evaluate the efficacy of human placental membrane products and standard of care versus standard of care alone in the management of nonhealing diabetic foot ulcers and venous leg ulcers.

A Real-World Registry of Chronic Wounds and Ulcers

WOUNDJOURNEY is a longitudinal, real-world, observational registry designed to capture the full clinical course and patient journey associated with chronic wounds and ulcers. Data are collected during routine care from over 1,400 clinicians across the USA and Puerto Rico using a highly structured certified electronic health record (EHR) or electronic data capture (EDC) system. Data are transmitted daily to the U.S. Wound Registry (USWR), a CMS-recognized Qualified Clinical Data Registry (QCDR). The registry captures real-time, research-ready data on patient demographics, comorbidities, wound characteristics, standard-of-care treatments, complications, and advanced therapeutics. It supports robust, fit-for-purpose real-world evidence generation by enabling risk-adjusted outcome analysis, comparative effectiveness research, and quality improvement across diverse sites of care.

SkinTE® for the Treatment of Wagner 1 Diabetic Foot Ulcers (COVER DFUS II)

The purpose of this study is to assess the safety and efficacy of SkinTE for treatment of Wagner grade 1 diabetic foot ulcers.

Evaluating a Lifestyle Intervention to Prevent Recurrence of Diabetic Foot Ulcers

People with diabetes often experience foot ulcers, which can harm their ability to move, lower their quality of life, and increase the chances of losing a limb. These diabetic foot ulcers (DFUs) commonly come back (recur) even after they've healed, so it's crucial to stop them from returning to avoid toe, foot , or leg amputation. While wearing special shoes to reduce pressure on the feet is essential for healing and preventing DFUs, many people struggle to follow this treatment plan once their ulcers have healed. This study aims to see if a lifestyle-focused program can help participants create daily routines and habits that make it easier to consistently use special shoes and take care of their diabetes and feet to prevent ulcers from recurring.

The Role of Skin Microecology in Diabetic Skin Lesions

This study is an observational study. Collect cotton swabs of the surface skin are obtained from the non-diabetic and diabetic patients hospitalized in the Nanfang Hospital of Southern Medical University. The investigators use omics technology to identify the structure and functions of cutaneous microbiome, analyze the characteristics of the skin flora of diabetic patients, and find the difference in skin microbiota among diabetic patients with different risk levels for developing into diabetic foot. Then, the participants will be followed up to compare the incidence of ulcers among different groups. And the skin tissues discarded during surgical operations of non-diabetic and diabetes patients are collected for pathological examination. Finally, based on the results of 16S high-throughput sequencing, metagenomics, etc., specific flora could be extracted from human skin flora cotton swabs, and animal experiments are performed to explore the effect of skin micro-ecology on diabetic skin lesions. The investigators will explore in animal experiments to regulate the influence of skin micro-ecology on diabetic skin lesions through treatment methods such as different hypoglycemic drugs and probiotic emulsions.

Multi-modal Quantitative Imaging of the Skin
