Exclusion Criteria:
- Subjects who meet any of the following criteria will be excluded from the study:
- Evolocumab and/or Alirocumab, or other targeted drugs to PCSK9, has been used at any time.
- Any therapeutic or research biological agents has been used during the first 6 months of baseline/random (Day 0).
- Participated in any clinical study within 3 months prior to baseline/random (Day 0).
- Any drug or health supplement that affects blood lipids or lipid metabolism during the first 30 days of baseline/random (Day 0), including but not limited to: Probucol, statins (e.g. Atorvastatin, Rosuvastatin, etc.), cholesterol absorption inhibitors (such as Ezetimibe), bile acid sequestrants (such as Cholestyramine), red yeast and hawthorn preparations, fibrates, high-purity fish oil preparations (or omega-fatty acids ≥ 1000 mg / day) and niacin preparation (nicotinic acid ≥ 50 mg), etc.
Start a new intense exercise or diet control within 30 days of random (Day 0) or major changes to previous diet and lifestyle (including exercise, smoking and drinking). The following conditions occur before the baseline/random (Day 0) 1 day (ie Day-1) need to be excluded:
- Creatine kinase (CK) ≥ 3 times the upper limit of normal (ULN) (Note: related to exercise), or
- Urinary cotinine is positive, or
- Positive alcohol saliva test.
- Previous or concomitant diseases (such as nephrotic syndrome, liver disease, diabetes, hypothyroidism, etc.) or any clinically significant abnormalities found in physical examinations, laboratory tests, and electrocardiograms, which would make the subject unsuitable for this study.
The medical history or clinical evidence indicates that the subject had severe acute or chronic disease (including not limited to: heart, kidney, nerves, endocrine, blood, immunity, infection, metabolic disorders, etc.), and the disease has not been controlled, which may confuse the outcome of the study or put the subject at risk judged by the investigator, The following situations need to be excluded:
- had major surgery in the last 6 months, or
- has been hospitalized (e.g. infection) in the last 3 months, or
- donated blood or blood loss ≥500 mL in the past 3 months, or
- has used any prescription or over-the-counter drugs in the past 1 month.
- Transplantation History of organs (such as heart, lung, liver, kidney, etc.) Malignant tumors history, except for cervical carcinoma in situ or surgically resected skin cancer (basal cells and squamous epithelial cells) for more than 5 years.
- Drug abuse or alcohol dependence in the past 1 year.
- HIV infection, or HIV antibody positive at screening visit.
- Syphilis infection, or serotonin antibody (TPPA) positive at screening visit.
- Hepatitis B surface antigen (HBsAg) was positive at screening visit.
- Hepatitis C virus (HCV) antibody was positive at screening visit.
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≥ 2 times the upper limit of normal (ULN); alkaline phosphatase and bilirubin ≥ 1.5 times the upper limit of normal (ULN).
- Allergy history to mammalian-derived biological agents, including monoclonal antibodies.
- Women during pregnancy and lactation.
- Any other investigator believes that the subject is not suitable for the study, such as the subject has potential compliance issues, cannot complete all tests and assessments according to the protocol requirements.
