About this study

Official title: Predictive and Diagnostic Biomarkers for Diabetic Foot Ulcers: Open Wound Master Study

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

Read the detailed description

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 The platform study is designed to be flexible so that it is suitable for a wide range of studies relevant to patients with open (active) DFUs.

This platform study will enroll patients with DFUs seen in an outpatient setting in diabetic foot and wound care clinics across a range of healthcare systems, including community settings and tertiary care hospitals, participating in the DFC.

The platform study will include common procedures that are applicable across the entire spectrum of DFUs (e.g., uniform biospecimen collections, clinical and usual care characteristics, social determinants of health, and patient reported outcomes). Blood, wound fluid (by a variety of methods), wound dressings, and debridement tissue (if debridement is performed during the participant's clinical wound care) will be collected from all participants to support a biorepository for concurrent and future research. Urine samples will be collected if participants agree to provide them, and collection will be encouraged. Biomarker-specific studies requiring additional data or biospecimens not required in the platform study will be included as appendices, as needed. Other biomarker-specific studies that use platform study biospecimens and study data will follow the DFC ancillary study process.

Eligible participants enrolled in the master protocol who signed the informed consent may be enrolled in multiple biomarkers sub studies associated with the master protocol without the need to sign an additional informed consent.

This platform study is non-interventional; no study prescribed agents or therapies are administered.

Eligible and consented participants are managed at each DFC site according to the usual clinical care, which is expected to be in line with the current standards of care recommendations1-3. The study will collect relevant details regarding the care provided at each clinic visit and participant outcomes.

Follow-up for participants will vary based upon the occurrence and timing of healing:

  • All participants will be followed every other week for one month and monthly thereafter until the wound is healed or week 52 if the wound has not healed.
  • Participants who experience wound healing prior to week 52 will have a confirmation visit 2 weeks later. These participants will also be assessed for recurrence of their DFU at weeks 52 and 78 via phone call or video visit.
  • Participants who experience wound healing at week 52 will have a confirmation visit 2 weeks later. These participants will also be assessed for recurrence of their DFU at week 78 via phone call or video visit.
  • Participants who do not experience wound healing by week 52 will have an additional phone call or video visit scheduled at week 78 to assess patient-reported wound healing, infection, or amputation with confirmation by electronic medical records (EMR), if available.

Study visits may occur in conjunction with the participant's scheduled clinical follow-up visits. After wound healing has been confirmed, the visit may be conducted by remote means.

The master protocol will enable evaluation of the time to healing over a 78-week period and of expectations on the natural history of wound healing in contemporary DFU participants. It also enables exploring rates of DFU recurrence in those who healed. These data will lead to more accurate DFU-specific standards of care guidelines that will have a direct impact and benefit in the clinical care, for a personalized approach.

General and biomarker-specific analyses will be performed. Participants who share common demographic or clinical characteristics may be pooled across substudies.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Wound Healing

    Proportion of participants with complete wound healing by week 52, defined as complete wound closure where there is skin re-epithelialization without drainage or dressing requirements at two consecutive study visits 2 weeks apart.

    Measured: 52 Weeks

  2. DFU Infections

    Proportion of participants who develop infections of the index DFU among those with no infections at baseline.

    Measured: 52 Weeks

  3. Amputations

    Proportion of participants who have an amputation of the limb associated with the index DFU.

    Measured: 52 Weeks

  4. Prediction Performance

    Measures of prediction performance (e.g., predictive power, AUC, ROC, Akaike information criterion) of biomarker(s) for each of the clinical outcomes: Wound Healing, DFU Infections, and Amputations described above.

    Prediction performance is measured by multiple statistical measures to assess ability of the biomarker to predict event risk for each of the three clinical outcomes.

    Measured: 52 Weeks

  5. Biospecimens Count

    Proportion of eligible participants providing biospecimens by site, and by type (serum, plasma, wound fluid, wound dressings, wound debridement tissue, urine).

    Measured: 52 Weeks

  6. Biospecimen Quality

    Proportion of biospecimens of adequate quality by type.

    Measured: 52 Weeks

  7. Standard of Care Prescription by Site

    Proportion of sites that prescribe the most current SOC into usual care, specifically for: (a) offloading; (b) vascular assessment; and (c) debridement.

    Measured: 52 Weeks

  8. Standard of Care Adherence

    Proportion of participants who adhere to physician-prescribed SOC therapies for their DFU care.

    Measured: 52 Weeks

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 9 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Wound Healing (time frame: 52 Weeks). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Sep 2026.
