Arms & Interventions
ASC11 tablets
Part 1: Subjects will receive ASC11 tablets on single ascending doses with proposed dose levels of ASC11 tablets: 100mg (cohort 1), 200 mg (cohort 2), 400mg (cohort 3) and 800 mg (cohort 4).
Part 2: Subjects will receive ASC11tablets 100 to 300 mg (including 3 cohorts) and ASC11 tablets 300 mg(cohort 4) twice daily (BID) for 5 consecutive days and receive a single dose in the early morning of Day 6.
Part 3: Subjects will be randomized to receive ASC11 tablets two single 200 mg or 300 mg doses (fed or fasted)
Intervention: ASC11 tablets (Drug)
RTV tablets
Part 1: Subjects will receive RTV tablets on 100 mg (cohort 1-4). Part 2: Subjects will receive RTV tablets 100 mg (including 3 cohorts) twice daily (BID) for 5 consecutive days and receive a single dose in the early morning of Day 6.
Part 3: Subjects will be randomized to receive two single 100 mg doses (fed or fasted)
Intervention: RTV tablets (Drug)
Placebo
Part 1 and 2: Subjects will be randomized to receive placebo
Intervention: Placebo (Drug)
