The subjects can communicate well with the investigators and complete the trial according to the protocol. Exclusion Criteria: 1. Allergic constitution or known history of allergy to the components of the study drug or similar drugs. 2. Antibody drugs targeting PCSK9 have been used within 6 months prior to screening, oligonucleotides targeting PCSK9 have been used within 12 months prior to screening. 3. There are currently medical disorders of clinical significance, including but not limited to, circulatory, hematological or hematopoietic diseases, respiratory, endocrine, urinary, digestive, neurological or psychiatric disorders, infections, tumors, severe trauma, or any other diseases that the investigator considers to be excluded or likely to interfere with the interpretation of the findings. 4. Those who underwent major surgery within 6 months prior to initial administration, or who planned to undergo surgery during the study. 5. Clinically significant abnormalities in vital signs, physical examination, electrocardiogram and laboratory examination. 6. The estimated glomerular filtration rate (eGFR) during screening was < 90 mL/min/1.73 m^2 (calculated by simplified MDRD formula). 7. During screening, any item of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), ?-glutamyltransferase (GGT), alkaline phosphatase (ALP) > 1.5×ULN (retest once within 1 week allowed). 8. During screening or baseline, subjects with prolonged QT/QTc interval (QTcF > 450 ms in male, > 470 ms in female). 9. Subjects with non-negative test for any of HBsAg, HCV antibodies, syphilis antibodies, and HIV antibodies. 10. Blood loss or blood donation of more than 200 mL within 3 months prior to administration (except for female menstrual period), and/or platelet donation within 2 weeks prior to administration. 11. Use of any drug, supplement, vitamin or dietary supplement known to affect lipid metabolism within 28 days prior to administration; use of any drug for therapeutic purposes (except topical drugs with local effects) within 14 days prior to administration or within the 7 half-lives of the drug (whichever is longer). 12. A history of drug abuse, and/or drug use within 3 months prior to screening, and/or habitual use of any psychotropic drug, including Chinese herbs. 13. Positive urine drug screening. |
