Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants will have their suspect skin lesion(s) photographed on a smartphone camera with a dermosopic lens attachment by their General Practitioner (GP). The process should take 2-3 minutes of their standard GP visit.
The GP will decide whether to biopsy each lesion. The images will then be analysed by an Artificial Intelligence (AI)-based tool, Deep Ensemble for Recognition of Malignancy (DERM) in real time, and immediately (within 1 minute) return a response to the GP. Where the GP has decided to biopsy the lesion, the response will be for the GP to continue as planned. Where the GP decided not to biopsy a lesions, but DERM recommends this, the GP may decide to change the patient management plan. The final decision on whether to biopsy each lesion is made by the GP (in agreement with the patient).

Efficacy
Statistical methods / analysis
The population will be split into two for comparison of the number of biopsies undertaken:
Control group - those lesions which the GP decides to biopsy, irrespective of DERM recommendation
Intervention group - those lesions which the GP would not have biopsied without DERM recommendation (irrespective of whether these are then biopsied)
We expect that 46.3% of lesions examined by GPs will be biopsied, and that 16.7% of lesions will be skin cancer postitive. In order to show that DERM reduces the percentage of unnessessarily biopsied lesions by one quarter (from 19.4% according to GP recommendation to 14.5% according to DERM recommendation), with 80% power, a sample size of 426 disease negative lesions are required. Consequently we will need to study 514 lesions.
Allowing for a 15% loss to follow up / poor image quality, the sample size for the study is expected to be between 750 and 1,000 patients.
