Assessment of Tissue Oxygenation Using Multispectral Imaging
An observational study of Diabetes Mellitus, run by Unity Health Toronto.

About this study
In Canada, the age-standardized prevalence of diabetes is on the rise (increasing from 3.3% in 1998/99 to 5.6% in 2008/2009 Public Health Agency of Canada (July 2011)) and is almost 1 in 10 globally. One of the most devastating complications of diabetes is the loss of a limb, (also known as lower extremity amputation, or LEA) due to complications resulting from a diabetic foot ulcer (DFU). Diabetics have a lifetime risk of 15-25% of developing a DFU1, which can lead to significant decreases in the quality of life, limitations in mobility, function and independence, and increased chance of depression and anxiety. In addition, diabetics post-LEA have high rates of mortality, with 30% dying in the first year post LEA and 70% at 5 years (more than the lifetime risk of dying from cancers). What differentiates a DFU that heals and one that progresses to LEA is often the vascularity of the limb; the diabetic lower extremity often becomes ischemic due to the vascular sequelae that are a common complication of diabetes, which hampers wound closure and immune clearance of wound-associated infections. Understanding limb oxygenation can direct treatment of a DFU, which may require limb revascularization to heal.
Read the detailed description
The MultIspectral MObile tiSsue Assessment (MIMOSA) Imager acquires digital images to calculate anatomical details of chronic wounds (e.g. diameter, surface area, and perimeter). The device can be worn from a lanyard, and clips onto a smartphone, using natural ambient lighting to capture images of a wound. The MIMOSA also uses up to 6 near-infrared LEDs to illuminate tissue with different wavelengths of light to assess tissue oxygenation.
The Food and Drug Administration (FDA) has previously approved a near-infrared device called the Kent camera for the assessment of tissue oxygenation. The goal of this proposal is to assess tissue oxygenation in a group of healthy volunteers with both the MIMOSA near-infrared imaging device and the Kent Camera.
The investigators hope to show that the MIMOSA Imager is substantially equivalent to the Kent Camera, and as such, the investigators are modeling the investigator's experiments on data previously published by the makers of the Kent Camera. The MIMOSA Imager is a contact-less device, and differs from the Kent Camera only in that it is smaller and more portable.

The Food and Drug Administration (FDA) has previously approved a near-infrared device called the Kent camera for the assessment of tissue oxygenation.
What is being measured
The primary outcome is the main question the study is designed to answer.
Tissue oxygenation is detected on both the MIMOSA Imager and Kent camera.
The MIMOSA Imager and Kent camera can both detect similar levels of tissue oxygenation.

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetes Mellitus, run by Unity Health Toronto.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 4 May 2018. Status can change between updates, so confirm with the study contact before making plans.
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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Karen Cross, MD, PhD (416-864-6060 ext. 77393, crosska@smh.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tissue oxygenation is detected on both the MIMOSA Imager and Kent camera. (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03516864, which also lists 10 linked publications.
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 4 May 2018.
