Global aging societies have a higher incidence of neurodegenerative diseases, e.g. dementia (50 M people), but early diagnosis for a prompt intervention and to avoid adverse outcomes is an unmet need. Currently, there are near 70 disease-modifying drugs in trial for Alzheimer’s disease (AD), but without efficient early detection they will not prove useful. Brain imaging to detect AD biomarkers using positron emission tomography (PET) is the gold standard for early neurodegeneration assessment, but traditional whole-body PET scanners are big, expensive, and therefore not routinely used. Positrigo is a Swiss start-up, with the aim to offer CortEx as a new dedicated PET brain scanner. It is a small, mobile and affordable device that occupies 5x less space and can deliver results at a fraction of today’s costs. It has the potential to become a game-changer in brain imaging and make AD diagnosis widely accessible. We have built a first functional prototype and achieved pre-clinical proof of concept. Now we need to optimize our scanner, obtain market access through regulatory processes, prepare manufacturing scaling-up, refine our commercialization strategies, engage with key stakeholders and plan market launch.
