  • 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);
