简要总结
The primary objective of this phase Ib study is to evaluate the safety and tolerability of multiple-ascending, subcutaneous (SC) doses of HC022 in SLE/CLE subjects. Secondary objectives of study are as follows: To estimate the PK parameters of multiple-ascending SC doses of HC022 in SLE/CLE subjects；To evaluate the immunogenicity of HC022 administered to SLE/CLE subjects.

结局指标
主要结局
Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
时间窗: Up to day 141
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An SAE is any untoward medical occurrence that at any dose: Results in death; in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); however, this does not include an event that, had it occurred in a more severe form, might have caused death; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect.
