Outcome results
Maximum Plasma Concentration (Cmax) for SI-722
SI-722 concentrations in plasma were measured using collected blood samples, and plasma PK parameters for SI-722 were estimated.
Time frame: 4 weeks
Population: The PK Population is defined as all subjects who received SI-722 and who provided at least 1 evaluable PK sample. One participant in the High Dose group was excluded from PK population because the subject discontinued before IP administration due to difficulty with drawing blood.
