Description of intervention(s) / exposure
Intervention: PN-10943A
Route of Administration: Oral liquid formulation
Part 1: Single Ascending Dose
Four cohorts will receive a single dose of PN-10943A 100mg, 300mg, 1000mg, 1400mg or placebo. Cohorts will run sequentially. Subjects will be dosed under fasting condition.
The same participants in Cohort 2 (300 mg PN-10943A or placebo) will return to the clinic after a period of at least 7 days to receive a second dose of PN-10943A immediately after ingestion of a standard high fat meal. The study schedule for the fed participants will be the same as the fasted participants.

Part 2: Multiple Ascending Dose
Five cohorts will be enrolled sequentially.
Cohort 5: 100 mg PN-10943A or placebo once daily for 14 days; Cohort 6: 300 mg PN-10943A or placebo once daily for 14 days; Cohort 6a: 300 mg PN-10943A once daily on 3 days (Days 1, 8 and 14); Cohort 7: 300 mg PN-10943A or placebo once daily for 14 days with meal interval of 60 minutes; and Cohort 8: 1000 mg PN-10943A or placebo once daily for 14 days.
Part 3: Cross over
Participants in Cohort 9 will receive PN-10943A (900 mg PN-10943A once daily for 5 days and 450 mg PN-10943A twice daily for 5 days) in a randomised crossover design. All participants in Cohort 9 will receive PN-10943A, no placebo.

Each cohort will enrol new subjects.

All dosing will be observed by clinic staff to ensure compliance. A record will be maintained by the investigational site which will account for all dispensing and return of any used and unused investigational products. At the end of the study the investigational products will be reconciled.
