- Presence of clinically significant vital signs values or of electrocardiogram (ECG) abnormalities during the screening period, as defined by an Investigator;
- ANA positive;
- During the screening period, the white blood cell count and C-reactive protein test results are abnormal and have clinical significance, hemoglobin: male <120g/L or female <110g/L;
- Smoking more than 5 cigarettes per day or equivalent amount of tobacco in the 3 months before screening;
- Subjects whose daily consumption of alcohol at the time of screening or at any time within the prior 6 months is more than 2 standard drinks, where 1 standard drink = 355 mL or 12 oz (1 can) of regular-strength (5%) beer; 150 mL or 5 oz wine; 45 mL or 1.5 oz liquor/spirits (40%);
- Subjects who had a history of drug abuse or tested positive for drugs within 1 year before screening;
- Subjects who have donated either more than approximately 500 mL of blood (exclusive plasma donation) within 3 mooth prior to screening or any plasma within 4 weeks prior to screening;
- Participate in any drug or vaccine clinical trial as a subject within 3 months before screening or prepare to be vaccinated during the study period to 2 months after the end of the study;
- Have taken drugs that may affect immune function within 6 months before screening or have received any monoclonal antibody or biological agent treatment within the previous 3 months and have taken prescription/over-the-counter drugs, herbal medicines, vitamins or other supplements within the previous 14 days;
- Drink more than 5 cups of coffee, tea or cola per day (150ml and above per cup);
- Women who are pregnant or breastfeeding;
- People with a history of fainting, bleeding and needles;
- The investigator believes that there are any subjects who are not suitable to participate in this trial.
