Study Summary

The purpose of this study is to determine whether luvadaxistat is superior to placebo in improving cerebellar function as measured with the average percentage of conditioned responses during the eyeblink conditioning (EBC) test.

Primary Outcome

EBC is a method used to investigate cerebellar-dependent learning. In EBC, a conditioned stimulus, a tone precedes but co-terminates with an unconditioned stimulus, an airpuff to the eyelid. Learning is demonstrated when an eyeblink (the conditioned response) occurs prior to the onset of the unconditioned stimulus. The percentage can range from 0% (no conditioned learning has occurred) to 100% (all responses are conditioned). Results are reported as least squares (LS) means at Day 8, determined
