Description of intervention(s) / exposure
This study will be conducted in two parts. There will be up to 9 cohorts with 8 subjects per cohort. Part 1 will evaluate single ascending doses of AR882 and Part 2 consists of cohorts to evaluate the pharmacokinetics of AR882 under various conditions.
Part 1 (Cohorts 1 to 5): Subjects in each cohort will be randomized to receive treatment with AR882 or placebo. Subjects randomised to Cohort 1-5 will ingest an oral suspension of AR882 of Dose A, Dose B, Dose C, Dose D and Dose E respectively after an overnight fast of at least 10 hours and will remain fasted until at least 4 hours post-dose.
Part 2 will include Cohorts 6 to 9. Cohort 6 is a stand-alone, fed-state cohort. Subjects randomised to Cohort 6 will ingest the oral suspension of AR882 (Dose B) approximately 30 minutes after subjects begin to consume a high-fat, high-calorie breakfast. Food is provided to participants at site. Subjects randomised to Cohort 7 will ingest the oral capsule of AR882 (Dose B) after an overnight fast (Food only, water is allowed during the period of fasting ad libitum) of at least 10 hours and subjects will remain fasted until at least 4 hours post-dose.
Cohorts 8 and 9 are combination arms including Allopurinol 300mg/AR882 (Dose B) and Febuxostat 40mg/AR882 (Dose B) respectively. In combination arm, sequence of ingestion will be AR882 immediately followed by Allopurinol or Febuxostat.
Sequence A: Allopurinol or Febuxostat on Day 1; AR882 and allopurinol 300 mg or Febuxostat on Day 8
Sequence B: AR882 and allopurinol or Febuxostat on Day 1;allopurinol or Febuxostat alone on Day 8.

The specification of dosages are listed below:
Dose A= 15mg
Dose B= 50mg
Dose C= 100mg
Dose D= 150mg
Dose E= 200mg
