Subjects with any of the following laboratory abnormalities at screening: total bilirubin (TBIL), gamma-glutamyl transferase (GGT), or alkaline phosphatase (ALP) \>1.5×ULN; alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>ULN. 5. Subjects with any of the following 12-lead ECG findings: QTcF \>450 ms or any other clinically significant abnormal ECG result. 6. Subjects with tattoos, scars, or birthmarks on the abdomen, upper arms, or thighs that may interfere with the assessment of injection site reactions. 7. Subjects who have used any prescription drugs, over-the-counter (OTC) medications, Chinese herbal medicines, or health supplements within 14 days prior to dosing; or for whom administration occurs within 5 half-lives of any prior medication (based on the longer period); or who have used any medication known to affect lipid metabolism within 90 days prior to screening. 8. Subjects who have received any live vaccine within 4 weeks prior to screening, or who plan to receive any live vaccine during the study. 9. Subjects who have used any antisense oligonucleotide (ASO) or small interfering RNA (siRNA) therapy within 12 months prior to screening. 10.
