  • Patients with a medical history of cardiovascular system, digestive system, endocrine system, urinary system, nervous system, hematology, immunology (including personal or family history of inherited immune deficiency), metabolic abnormalities, and researchers believe that the current clinical significance;
  • Allergy to any of the ingredients of the drug, or a history of allergy to drugs, foods, pollen or other substances, in particular a known allergy to protein foods, or a history of respiratory allergic disease;
  • Patients who cannot tolerate venipunctures or have a history of fainting needles and fainting blood;
  • Patients who have undergone surgery within 6 months prior to the use of the investigational drug that researchers judge will affect drug absorption, distribution, metabolism, and excretion; Or have undergone surgical procedures within 4 weeks prior to the use of the investigational drug; Or plan to undergo surgical procedures during the study period;
  • Used any drug (including prescription drugs, over-the-counter drugs, Chinese herbs, health care products, etc.) within 14 days before the use of the experimental drug;
  • Persons who have received the vaccine or live attenuated vaccine within 14 days prior to the use of the investigational product, or who plan to receive the vaccine during the trial period;
  • People who donated blood or lost a large amount of blood (\>400mL) within 3 months prior to the use of the investigational drug, received blood transfusions or used blood products, or intended to donate blood or blood components during or within 3 months after the end of the trial;
  • Drug abusers or those who have used soft drugs (e.g., cannabis) or hard drugs (e.g., cocaine, PCP, etc.) within one year prior to the use of the investigatory drug;

  • Alcoholics or regular drinkers in the six months prior to the use of the experimental drug, i.e. drinking more than 14 units of alcohol per week (1 unit =360mL beer or 45mL spirits with 40% alcohol or 150mL wine); Or unwilling to stop drinking alcohol or any products containing alcohol during the trial;
  • Those who consumed excessive amounts of tea, coffee and/or caffeinated beverages (more than 8 cups, 1 cup =250mL) per day, or did not agree to stop drinking tea, coffee and/or caffeinated beverages during the study period;
  • Eat any diet (including grapefruit or grapefruit products, dragon fruit, mango, grapefruit, orange, etc.) that may affect the metabolism of the drug in the body within 7 days prior to the use of the investigatory drug, or any other diet that the researcher considers to affect the absorption, distribution, metabolism or excretion of the drug, or do not agree to stop eating the above diet during the trial period;
  • Those who have special requirements for diet and cannot comply with a unified diet;
