Center without Walls for PET Ligand Development for Alzheimer's disease related dementias (ADRDs) (U19 Clinical Trial Optional)

This funding opportunity announcement (FOA) supports the development of PET radioligands that identify proteinopathies or pathological processes associated with the human biology of Alzheimer's disease related dementias (ADRDs). Activities supported under this FOA include, but are not limited to the in vitro screening of existing ligands against human ADRD brain tissue, medicinal chemistry support for development of new compounds and improvement of existing ligand specificity and selectivity, initial screening of ligands in appropriate animal models, and radioligand formulation and first-in-human testing. The Center without Walls should encompass research that will move promising ligands through in vitro and in vivo optimization to first-in-human studies. Applications must include an administrative core, a medicinal chemistry core, a clinical core, a scientific governance structure, and a minimum of two research projects with milestone plans that address workflows for screening of existing and newly derived ligands against human ADRD tissue and appropriate animal models. Synergy must be evident among Center research projects and cores, such that successful completion of the aims could not be accomplished without the Center structure. This FOA is in response to the Alzheimer's Disease Related Dementias (ADRD) challenges outlined in the 2016 update to the National Plan to Address Alzheimer's Disease.
