Initiation of a Phase 2 Multicenter Study of 18F-APN-1607, a Novel Diagnostic PET Imaging Tracer for the Characterization of Tau Burden in Alzheimer's Disease

Besides detecting tau aggregates in AD, ¹⁸F-APN-1607 is unique among the tau PET tracers currently in development because it can also visualize 4-repeat tau aggregates characteristic of rare tauopathies, including progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and the great majority of frontotemporal dementia (FTD) due to tau mutations. Thus, ¹⁸F-APN-1607 may be able to offer broader utilities to detect tau distribution patterns in all tauopathies. This could be valuable for testing tau-focused treatments for AD and other tauopathies and possibly in the future even be clinically useful.

In addition to the Phase 2 study in AD, APRINOIA is establishing a clinical research network with leading imaging centers worldwide to conduct medical research with ¹⁸F-APN-1607. Such research includes clinical/imaging correlation studies, investigation of longitudinal tau pathology progression and spread in individual tauopathies, exploration of potential utilities in differential diagnosis, and studies to develop new AI-based tau PET image analytical tools.
