Clinical Study #1

Background & Aim

The study's primary objective was to determine the diagnostic precision of the AI-based medical device Dermalyser by answering at which level Dermalyser can identify melanomas among cutaneous lesions assessed in clinical use due to any degree of malignancy suspicion.

The primary endpoint was measured by testing if Dermalyser gives correct results as compared with the final diagnosis of the lesion analysis (the final classification by histopathology (PAD) and/or Dermatologist assessment) in at least a certain proportion (π) of the analyses.

A secondary objective was to evaluate the usability and applicability in the clinical practice of Dermalyser by medical professionals and to gain an increased knowledge and understanding of how digital tools enhanced by AI can assist physicians with the proper support for an earlier diagnosis of melanoma. Towards this goal, users were asked to rate Dermalyser via a series of questions, including a System Usability Scale.
