Study Endpoints
Primary Endpoints
The primary objective of this study is to assess the safety and tolerability of a single SC dose of HST101 in Chinese healthy adult study participants with elevated LDL-C level(International Standard Unit: mmol/L)
57 days

Safety and tolerability will be assessed by the incidence and severity of treatment emergent adverse events

Secondary Endpoints
To assess the pharmacokinetic characteristics and dose proportionality relathionship of HST101 following a single SC dose
57 days
To assess the PD effect of a single SC dose of HST101 on serum unbound (free) PCSK9 concentrations and serum LDL-C concentrations
57 days
To assess the effect of a single SC dose of HST101 on blood lipids including TC, HDL-C, VLDL-C, and TG
