Moleculight i:X™ in Wound Healing

January 23, 2018 updated by: The Leeds Teaching Hospitals NHS Trust

The Use of Moleculight i:X™ in the Management of Diabetic Foot Ulcers: A Pilot Study

Diabetic foot disease is a global health problem. Diabetes affects over 450million people worldwide, expected to rise to 1 in 10 people by 2040. 60-70% will lose sensation in their feet and up to 25% will develop a diabetic foot ulcer (DFU - a wound on the foot). More than half of DFUs become infected requiring hospitalisation and 20% of infections result in amputations contributing to 80% of non-traumatic amputations performed in the developed world. DFUs cost the NHS £1billion in financial year 2014-15.

A diabetic foot ulcer is a form of chronic wound. Chronic wounds are wounds that fail to progress through the normal phases of wound healing in an orderly and timely manner and become hard to heal. Almost all chronic wounds are known to have bacteria within and this is termed colonisation. Wounds can progress from being colonised to becoming infected. The concentration of bacteria can predict delayed healing or infection.

This study aims to use a novel hand held device, Moleculight i:X™, in a pilot study to investigate the clinical effectiveness and decision making associated with its use in the assessment of DFUs. Moleculight i:X™ is a hand held device that emits violet blue light. By controlling distance from the wound and ambient light, Moleculight i:X™ identifies bacteria above a pre-determined concentration by identifying natural fluorescence in the bacteria cell wall.

Patients attending a specialist DFU clinic will be screened and if eligible and consenting will be recruited. Patients will be randomised into two groups; those who receive treatments as usual (TAU) alone (in line with NICE guidelines) and those that receive TAU plus Moleculight i:X™ imaging. The main objective is to describe the proportion per group with healed DFUs at 12week follow up in these two comparable groups of 30 patients each.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
60

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Group 1 - Interventional Treatment
Participants in this group have been randomised to receive application of violet blue light administered by the hand held Microlight i:X device in addition to routine care of their foot ulcer. This intervention will be administered four times during the study.
Device: Moleculight i:X™ fluorescence imaging
Moleculight i:X™ is a hand held device that emits violet blue light. By controlling distance from the wound and ambient light, Moleculight i:X™ identifies bacteria above a pre-determined concentration by identifying natural fluorescence in the bacteria cell wall.
No Intervention: Group 2 - Usual care
This group receive routine care and no additional intervention.
