Brief summary
This is a phase Ⅰ，single-center, randomized, double-blinded, placebo-controlled, single ascending dose trial of SY-009 in healthy subjects.
Detailed description
This is a randomized, double-blind, placebo-controlled, dosed tolerability, pharmacokinetic / pharmacodynamic study of a single oral SY-009 capsule for Chinese healthy subjects. Plan to screening no more than 64 healthy subjects ， dividing them into 7 dose groups.
Interventions
DRUGSY-009
The study will be initiated in healthy subjects at a 0.5mg dose that is the maximum recommended starting dose(MRSD) . Doses will be escalated in subsequent dosing process, after appropriate review of safety data. The subsequent planned doses are 2,5, 10, 20, 40mg successively. The increment of the dose escalation may be reduced, a lower dose may be administered following data review.
