Lesion Area Mapping Assistant
Read full descriptionHide full description
The Lesion Area Mapping Assistant (LAMA) is a mobile application designed to assist trained clinician raters in documenting and assessing dermatologic lesions through an image-first workflow. The application provides tools to support consistent capture, classification, and measurement of lesions associated with Hidradenitis suppurativa (HS). LAMA is intended for use by qualified clinicians and study personnel who have been authorized by their sponsoring organization or study site. Access to the application is provided by the sponsoring organization or research site. The application does not recruit participants, enroll patients, or obtain informed consent. Informed consent and study enrollment are conducted by the responsible study site in accordance with established clinical research procedures before any use of the application. LAMA functions as a secure data capture and assessment tool used by trained professionals to document observations requested by a study team or healthcare organization.
