Study: NCT05462340

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: [18F]ASEM
Description: \[18F\]ASEM demonstrated excellent imaging properties, as was recently confirmed by others. \[18F\]ASEM is the 1st validated α7 human PET radiotracer to examine α7-nAChR characteristics in the living brain of SCZ patients. Previous α7 studies in the SCZ literature were done using brains harvested post-mortem, and under variable storage conditions. The proposed studies will also determine α4β2-nAChR \[18F\]AZAN binding characteristics in the same subjects who complete α7-nAChR PET studies with \[18F\]ASEM, which will be highly significant for understanding these receptors in SCZ.

Intervention: [18F]AZAN
Description: The most widely used PET radioligand for human imaging of α4β2-nAChR is 2-\[18F\]FA. Because 2-\[18F\]FA exhibits very slow brain kinetics, the investigators developed \[18F\]AZAN, a highly α4β2 specific tracer with optimal brain kinetics. Therefore, the proposed studies will utilize \[18F\]AZAN to determine α4β2-nAChR \[18F\]AZAN binding characteristics in the same subjects who complete α7-nAChR PET studies with \[18F\]ASEM, which will be highly significant for understanding these receptors in SCZ.
