About this study

Official title: Effectiveness of an Image Analysing Algorithm to Diagnose Melanoma Compared to Gold Standard Histological Determination

Prospective, single-arm, cross-sectional, study to establish the effectiveness of MIAA to detect melanoma in pigmented lesions, compared to gold standard histological determination.

Read the detailed description

Skin Analytics Limited have developed an algorithm (MIAA) which reviews photographs of pigmented lesions to determine whether melanoma is likely to be present. This study aims to establish how well MIAA determines the presence or absence of melanoma, compared to a biopsy.

Pigmented lesions that a dermatologist has decided to biopsy, and are suitable for photographing, will be photographed up to five times in a single visit. Three different camera will be used, and two different dermoscopic lens attachments will be used on smartphone cameras. Images will be analysed by MIAA and the results compared to the biopsy result. Clinicians, patients and the statistical analysis team will be blinded to the result of MIAA.

At least 65 pigmented lesions positive for melanoma (as determined by biopsy) are required, which is predicted to mean 1250 patients will be recruited.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Melanoma Image Analysis Algorithm (MIAA)Device

    The images will be analysed by MIAA (Melanoma Image Analysis Algorithm). The MIAA result for PLs that are biopsied will be compared to the diagnosis made from the biopsy. The MIAA result for PLs not biopsied will be compared to clinician diagnosis.

Study groups in NCT02612168
Study groupRoleWhat they receive
All patientsExperimentalEach patient will have any pigmented lesions (PLs) which are due to be biopsied, two PLs not due for biopsy and one patch of healthy skin photographed. Each will be photographed using three cameras: A standard DSLR and two smartphones with a dermoscopic lens attachment. Photographic images will be analysed by Melanoma Image Analysis Algorithm (MIAA)

Questions about this trial

What is this clinical trial studying?

A study testing Melanoma Image Analysis Algorithm (MIAA) in people with Malignant Melanoma, run by Skin Analytics Limited at 7 sites in United Kingdom.

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 4 inclusion and 1 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: finished, as of the sponsor's last update on 25 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Area Under the Curve of a Receiver Operating Characteristic (AUROC) curve of MIAA result, using a maximum likelihood estimation (MLE) from all of the available images of biopsied lesions, compared to the biopsy result (time frame: Study completion, on average 2 weeks). 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 25 Jan 2019; AzTrials last refreshed its copy on 27 Oct 2026.
