A Comparison Study of ADC189 Bioavailability Between Tablet and Granule in Healthy Chinese Adult Male Subjects, and the Safety and Pharmacokinetics of Ultra-high Dose ADC189
A Comparison Study of ADC189 Bioavailability Between Tablet and Granule in Healthy Chinese Adult Male Subjects, and the Safety and Pharmacokinetics of Ultra-high Dose ADC189
Part 1 of this study will compare the pharmacokinetic performance of tablet and granule formulations of ADC189 under fasted conditions in healthy volunteers. A randomized, two-period, two-treatment crossover design is used. In each period, each volunteer will receive a single oral dose of the tablet or granule formulation without food.
The purpose of Part 2 study is to determine the safety and pharmacokinetics of ultra high dose of ADC189 in healthy subjects.
In Part 1 study, a total of 32 subjects were randomly divided into two groups, A and B, with 16 subjects in each group. After a 28-day screening period, on the first day of Period 1 (D1), subjects in group A took ADC189 granules (a single oral dose, 45mg), and subjects in group B took ADC189 tablets (a single oral dose, 45mg), all subjects were under fasted conditon. In Period 2, two groups will change to the fomulation which is different in Period 1 respectively, and all the steps will keep the same as Period 1. Each period lasts for 15 days, and have a 7-day interval between 2 periods. Blood samples will be taken, pharmacokinetic and saftey profiles will be observed.
In Part 2 study, the ultra high dose of ADC189 (a single oral dose, 180mg) will applied in 8 healty adult male subjects. The pharmacokinetic and saftey profiles will be observed during the following 15 days, and blood sample will be taken.
