Outcomes
Primary outcome [1] 321905 0
To evaluate the pharmacokinetics of Oral ES-481
Timepoint [1] 321905 0
Blood for PK analysis will be collected at 8 AM (time 0 hours, prior to the oral dose of study drug /placebo and after an overnight fast, at 0.25, 0.5, 1, 2, 4, 8, 12, 16, and 24 hours following the oral administration of study drug/placebo on Day 1 and at 36 and 48 (Day 2) hours after the oral administration of study drug/placebo on Day 2.

Below PK parameters will be assessed derived from plasma data.

Peak concentration in plasma (Cmax);
Time to peak concentration in plasma (Tmax);
Area under the plasma concentration-time curve (AUC) from time zero to last quantifiable concentration (AUClast);
AUC from time zero to infinity (AUCinf);
Apparent total body clearance from plasma (CL)
Apparent renal clearance from plasma (CLr);
Elimination half-life (t½);
Secondary outcome [1] 376637 0
To evaluate the safety and tolerability of Oral ES-481 after a single dose
Timepoint [1] 376637 0
Adverse events will be monitored throughout the study from the date of informed consent signed.

Vital signs will be measured at screening, before administration of ES-481; on Day 1 and at 0.5, 1, 2, 4, 12, 24 (Day 1), 48 (Day 2), 72 (Day 3), and 96 (Day 4) hours after the oral administration of study drug or placebo and at the follow-up visit.

Physical examination will be performed at screening, Day-1, and 24 (Day 1), 48 (Day 2), 72 (Day 3) and 96 (Day 4) hours after the oral administration of study drug/placebo and at the follow-up visit.

Neurological assessment/examination will be performed at screening, Day -1, after check-in, and on Day 1 approximately 3, 6, and 24 hours after the administration of study drug/placebo.

12-lead ECG will be collected at pre-dose on Day 1 and post dose at 0.5, 1, 2, 4, 6, 9, 12, and 24 hours on Day 1, 48 (Day 2), 72 (Day 3) and 96 (Day 4) hours and at the follow-up visit.
