Study summary

This is a 12 week, randomized controlled trial. There are 2 arms and 20 patients with non healing diabetic foot ulcer allocated in each arm. One arm receives i:X guided treatment and the other arm receives standard of care treatment. Our primary objective is to compare the wound area reduction in both arms.

Study population

Male and female subjects presenting with non healing diabetic foot ulcer

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Male or female patients presenting with chronic DFU
  • The chronic DFU has a surface area that has reduced \<25% in the previous 4 weeks1 prior to first study visit
  • Patient has been receiving treatment for their DFU for less than 12 weeks.
  • The chronic DFU is > 1 cm2 in area and less than 15 cm in length (max. diameter)
  • 18 years or older
  • Willing and able to make all required study visits

Exclusion criteria

Exclusion Criteria:

    • Patients categorized as having a maintenance wound

      • Use of skin substitutes or hyperbaric oxygen therapy or surgical intervention
      • Treatment with an drug within 1 month of enrolment
      • Presents with chronic (>10 mg/kg for >30 days) systemic corticoids before enrolment
      • Has ABI \<0.5 (measured within 3 months of randomisation)
      • Undergoing chemotherapy or is
      • Diagnosed with Charcot disease or ulcers from electrical, chemical or radiation burns, or presents with collagen vascular disease, ulcer , untreated osteomyelitis or cellulitis
      • Recombinant or autologous growth factors or skin/dermal substitutes within 30 days of enrollment
      • Inability or unwillingness to consent
Terms in these criteria, in plain language(3)

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Groups and cohorts

  • ARM 1

    Patients receive standard of care treatment for their diabetic foot ulcer

  • ARM 2

    Patients receive MolecuLight i:X guided treatment for their diabetic foot ulcer

    Device: MolecuLight i:X Imaging Device

Interventions

  • DeviceMolecuLight i:X Imaging Device

    The MolecuLight i:X Imaging Device uses built-in light-emitting diodes (LEDs) emitting 405 nm violet excitation light to illuminate the wound during fluorescence imaging in (FL-Mode). The light excites biological components of the wound and surrounding tissues. Non-biological components may also fluoresce although their presence in wounds is less common, provided the wound has been cleaned following standard care protocols. The resulting wound fluorescence wavelengths emitted are typically between 420 - 700 nm in the visible wavelength spectrum. In FL-mode, a customized fluorescence emission filter, which is mechanically placed in front of the built in imaging sensor and allows real-time capture of wound, limits the visualization of fluorescence to wavelengths between 500-545 nm, which typically appears green in color, and 600-665 nm, which typically appears red in color.

What researchers measure

Primary outcomes

  1. Rate of change in wound area of diabetic foot ulcers in ARM 2 vs ARM 1

    ARM 2 vs ARM 1 Evaluate change in wound area over 12-week period

    Time frame: 5 months

Secondary outcomes

  1. Wound Healing Rate

    ARM 1 vs. ARM 2 1. Evaluate increase in wound healing rate over 12-week period 2. Evaluate differences in clinical infection i. time to eradicate an infection ii. incidence of new infection (i.e. infection avoidance) 3. Determine if MolecuLight i:X images taken at baseline can predict non-healing wounds, region for debridement and/or wounds at risk of infection (based on fluorescent signatures) at 6 and 12 weeks.

    Time frame: 5 months

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

Ran from Feb 2020 to primary completion in Apr 2024, 49 months.

Of 90 observational studies under Diabetic Foot, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 59. This study's 49 months is above that.

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 Jul 7, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
