Study Summary

This study is designed to evaluate treatment effects of ATH-1017 (fosgonimeton) in mild to moderate Alzheimer's subjects with a randomized treatment duration of 26-weeks.

Primary Outcome

ERP P300 was a method of recording brain activity elicited by external stimuli, for example (e.g.), an oddball auditory stimulus, particularly of working memory access. The participant had to perform a task related to auditory stimuli in order to assess the P300 component (latency). The stimulus consisted of an oddball paradigm with 2 sound stimuli. Stimuli were presented through headphones and auditory stimulation for P300 was assessed in a recording lasting up to 10 minutes. It was calculated
