Study Arms (2)

AD16

EXPERIMENTAL

AD16 tablets should be administered only in the morning on the day of the first dose and on the ninth day after the first dose. Fasting is required for at least 10 h before administration.Two dosing cohorts received AD16 From the third day to the eighth day, the medicine was administered twice a day, 1 h before breakfast, 1 h before dinner or 2 h after dinner, with a 12 h interval (time window ±1 h).The duration of oral AD16 tablets was nine days.

Drug: AD16 30mg、40mg

AD16 placebo

PLACEBO COMPARATOR

AD16 placebo tablets should be administered only in the morning on the day of the first dose and on the ninth day after the first dose. Fasting is required for at least 10 h before administration.Two dosing cohorts received AD16 placebo From the third day to the eighth day, the medicine was administered twice a day, 1 h before breakfast, 1 h before dinner or 2 h after dinner, with a 12 h interval (time window ±1 h).The duration of oral AD16 placebo tablets was nine days.

Drug: AD16 Placebo 30mg、40mg
