Clinical Trial Description

This clinical study is a single-center, randomized, double-blind, placebo-controlled Phase 1 clinical study to assess the PK characteristics and safety and tolerability of single and multiple dose daridorexant in healthy adult Chinese subjects. This study will consist of a 20-day screening period, a 1-day baseline, a 11-day in patient period, and a 27-day follow-up period. The subjects will arrive at the study site on Day -1, and the subjects will be discharged from the study site on Day11. 32 healthy subjects (18-55 years) will be randomized. Two dose levels are planned (25 mg and 50 mg). 16 healthy subjects will be randomized with a ratio of 3:1 to receive 25mg daridorexant or matched placebo and another 16 healthy subjects will be randomized with a ratio of 3:1 to receive 50mg daridorexant or matched placebo. On Day 1, each subject will receive a single dose of daridorexant or placebo in the morning under fast conditions and PK samples will be collected up to 72 h post dose. Subject will receive repeated doses of daridorexant or placebo from day 4 to day 8 (QD) in the morning under fasting conditions and PK samples will be collected up to 72 h post last dose. The final follow-up visit will be conducted on Day 38, 30 days after the last dose. ;
