Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will be conducted at a single center. There will be up to 4 cohorts with 10 subjects per cohort.
Subjects in each cohort will be randomized to receive treatment with AR882 (8 subjects) or placebo (2 subjects). Cohorts 1 to 4 will enroll sequentially following review of safety and PK data of prior cohorts by the Investigator and Sponsor Medical Monitor.
Dosing: Subjects will ingest Investigational Product(IP) after an overnight fast of at least 10 hours and will remain fasted until at least 4 hours post-dose. Subjects may ingest water ad libitum during the period of fasting before and after IP administration. Starting dose of IP will be 50mg.
Planned cohorts;
Cohort 1: (50mg) AR882 or placebo once daily for 10 days
Cohort 2: (75mg) AR882 or placebo once daily for 10 days
Cohort 3: (100mg) AR882 or placebo once daily for 10 days
Cohort 4 (less than or equal to 100mg): Subjects will be dosed with a lower or intermediate dose of AR882 or placebo once daily for 10 days. Decision to proceed with Cohort 4 will be based on preliminary review of previous cohorts’ PK/PD and Safety/tolerability data.

Strategies used to monitor adherence to the intervention: Laboratory tests and pharmacokinetic analyses.
Strategies used to ensure compliance with the fasts: Inpatient stay and observation
