Primary Outcome Measures :
  1. AUC of ASC40 [ Time Frame: Up to 24 days ]
    Evaluate the Area under the Plasma Concentration Versus Time Curve after single oral dose of ASC40 administered to healthy volunteers in the presence or absence of CYP3A inhibitor or inducer.

  2. Cmax of ASC40 [ Time Frame: Up to 24 days ]
    Evaluate the Peak Plasma Concentration after single oral dose of ASC40 administered to healthy volunteers in the presence or absence of CYP3A inhibitor or inducer.


Secondary Outcome Measures :
  1. t1/2 of ASC40 [ Time Frame: Up to 24 days ]
    Evaluate the Terminal-Phase Half-Life after single oral dose of ASC40 administered to healthy volunteers in the presence or absence of CYP3A inhibitor or inducer.

  2. CL/F of ASC40 [ Time Frame: Up to 24 days ]
    Evaluate the Apparent Systemic Clearance after single oral dose of ASC40 administered to healthy volunteers in the presence or absence of CYP3A inhibitor or inducer.

  3. Vd/F of ASC40 [ Time Frame: Up to 24 days ]
    Evaluate the Apparent Volume of Distribution after single oral dose of ASC40 administered to healthy volunteers in the presence or absence of CYP3A inhibitor or inducer.

  4. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [ Time Frame: Up to 24 days ]
    Occurrence of Serious Adverse Event (SAE), Adverse Event (AE) resulting in treatment discontinuation and/or dose reductions, and AE of special interest, from baseline up to 24 days.
