NCT05787041

Brief Summary

The study was a single-center, randomized, open-access, two-crossover, single-dose study design with 16 subjects to evaluate the pharmacokinetics of a high-fat diet on a single dose of oral AD16 tablets in healthy Chinese adults and the safety of a single dose of oral AD16 tablets in healthy Chinese adults. Compared with fasting administration, a high-fat diet reduced the rate of AD16 tablet absorption in healthy adult subjects and had no effect on overall exposure to AD16. The elimination and distribution characteristics of AD16 in vivo were similar under the conditions of feeding and fasting administration. A single dose of AD16 tablets after fasting and high fat diet showed good safety.

Study Arms (2)

High-fat diet group

EXPERIMENTAL

A single dose of AD16 tablets was taken orally after a high fat diet

Other: high-fat diet group(AD16 20mg)

Fasting group

EXPERIMENTAL

A single dose of AD16 tablets was taken orally under fasting conditions

Other: fasted group(AD16 20mg)

Interventions

AD16 was administered with 240 mL water 30 minutes after the subjects ate a high-fat, high-calorie food.

High-fat diet group

Subjects took AD16 on an empty stomach and fasted within 4 hours after taking the drug.

Fasting group
