Brief summary
This is a phase Ⅰ，single-center, randomized, double-blinded, placebo-controlled, single ascending dose trial of SY-008 in healthy subjects.
Detailed description
This is a randomized, double-blind, placebo-controlled, dosed tolerability, pharmacokinetic / pharmacodynamic study of a single oral SY-008 capsule for Chinese healthy subjects. Plan to screening total of 54 healthy subjects ， dividing them into 6 dose groups.
Interventions
DRUGSY-008
The study will be initiated in healthy subjects at a 2-mg dose that is expected to have minimal pharmacologic effect. Doses will be escalated in subsequent dosing process, after appropriate review of safety data. The subsequent planned doses are 6, 12, 18, 24, 30mg successively. The increment of the dose escalation may be reduced, a lower dose may be administered following data review.
