Study summary

The hypothesis of this study is based on the premise that pressure-distributing materials with superior biomechanical and tissue response properties will be capable of improving the healing rate of neuropathic ulcers.

The overarching objective of the present project is to assess the influence of the nature and method of application of the materials under study on tissue response, the reduction of pressure on the sole of the foot, and the healing of neuropathic ulcers in patients with diabetes mellitus.

Read the detailed description

The study is divided into two distinct phases:

The following analysis is concerned with the characteristics of materials that are employed for the purpose of the distribution of pressure. This will entail the meticulous analysis of the response exhibited by the materials, with the objective of ascertaining their true biomechanical behaviour in volunteers devoid of active ulcers.

The materials selected in the first part will be applied for the treatment of revascularised neuroischaemic ulcers. This will determine which of the materials is the most suitable for treating the lesion.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Near-infrared perfusion index (NIR perfusion)

    Hyperspectral imaging was performed using the TIVITA® 2.0 camera (Diaspective Vision GmbH, Germany). This non-contact, non-invasive device captures images across multiple wavelengths within the visible and near-infrared spectrum (500-1000 nm), enabling assessment of microcirculatory parameters up to a tissue depth of approximately 8 mm. The device provides an image resolution of 640 × 480 pixels, with an acquisition time of 6.4 seconds. Images were analyzed using TIVITA® Suite software by selecting a circular region of interest adjusted to the metatarsal head and offloading area under study.

    Time frame: Baseline and 4 days

Secondary outcomes

  1. Thermography

    The images will be captured using the FLIR C8 thermal imaging camera. The camera in question features a true thermal resolution of 320 × 240 pixels (76,800 measurement points) and MSX® technology, which combines visual and thermal details into a single image, thereby facilitating the detection of anatomical abnormalities. Thermographic variables of interest included differences in absolute temperature values (maximum and mean temperature) within the region of interest corresponding to the offloading area.

    Time frame: Baseline and 4 days

  2. Peak pressure (Pmax)

    Peak pressure (Pmax) measured at the metatarsal head corresponding to the highest dynamic pressure. Plantar pressures were assessed using the EPS+R platform (Loran Engineering®, Bologna, Italy). The platform measures 50 × 70 × 4 mm, weighs 7 kg, and incorporates 2304 resistive sensors measuring 9 × 9 mm each. The pressure range is 50-350 kPa, with a maximum acquisition frequency of 100 Hz. Biomech® Studio 2019 software (LetSense Srl, Loran Engineering®) was used for data analysis.

    Time frame: Baseline and 4 days

  3. Tissue oxygen saturation (StO₂)

    Hyperspectral imaging was performed using the TIVITA® 2.0 camera (Diaspective Vision GmbH, Germany). This non-contact, non-invasive device captures images across multiple wavelengths within the visible and near-infrared spectrum (500-1000 nm), enabling assessment of microcirculatory parameters up to a tissue depth of approximately 8 mm. The device provides an image resolution of 640 × 480 pixels, with an acquisition time of 6.4 seconds. Images were analyzed using TIVITA® Suite software by selecting a circular region of interest adjusted to the metatarsal head and offloading area under study.

    Time frame: Baseline and 4 days

  4. Tissue hemoglobin index (THI)

    Hyperspectral imaging was performed using the TIVITA® 2.0 camera (Diaspective Vision GmbH, Germany). This non-contact, non-invasive device captures images across multiple wavelengths within the visible and near-infrared spectrum (500-1000 nm), enabling assessment of microcirculatory parameters up to a tissue depth of approximately 8 mm. The device provides an image resolution of 640 × 480 pixels, with an acquisition time of 6.4 seconds. Images were analyzed using TIVITA® Suite software by selecting a circular region of interest adjusted to the metatarsal head and offloading area under study.

    Time frame: Baseline and 4 days

  5. Tissue wáter index (TWI)

    Hyperspectral imaging was performed using the TIVITA® 2.0 camera (Diaspective Vision GmbH, Germany). This non-contact, non-invasive device captures images across multiple wavelengths within the visible and near-infrared spectrum (500-1000 nm), enabling assessment of microcirculatory parameters up to a tissue depth of approximately 8 mm. The device provides an image resolution of 640 × 480 pixels, with an acquisition time of 6.4 seconds. Images were analyzed using TIVITA® Suite software by selecting a circular region of interest adjusted to the metatarsal head and offloading area under study.

    Time frame: Baseline and 4 days

  6. Tissue lipid index (TLI)

    Hyperspectral imaging was performed using the TIVITA® 2.0 camera (Diaspective Vision GmbH, Germany). This non-contact, non-invasive device captures images across multiple wavelengths within the visible and near-infrared spectrum (500-1000 nm), enabling assessment of microcirculatory parameters up to a tissue depth of approximately 8 mm. The device provides an image resolution of 640 × 480 pixels, with an acquisition time of 6.4 seconds.

    Time frame: Baseline and 4 days

  7. Mean pressure (Pmean)

    Mean pressure (Pmean) measured at the metatarsal head corresponding to the highest dynamic pressure. Plantar pressures were assessed using the EPS+R platform (Loran Engineering®, Bologna, Italy). The platform measures 50 × 70 × 4 mm, weighs 7 kg, and incorporates 2304 resistive sensors measuring 9 × 9 mm each. The pressure range is 50-350 kPa, with a maximum acquisition frequency of 100 Hz.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2021 (actual). Primary completion is estimated for Jan 2027, 69 months after the start.

Of 62 non-industry interventional studies with no phase under Diabetes Complications, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 41. This study's planned 69 months is above that.

Counting every sponsor, half of 69 studies reached it within 28 months; a quarter within 12 and three quarters within 41.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 2, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
