Have undergone any major surgery or surgery affecting drug absorption, distribution, metabolism, excretion within the 3 months prior to screening, or are scheduled to undergo surgery during the trial period (major surgery is defined as surgery on the intracranial, chest, abdomen, pelvic, or limb organs that result in major tissue trauma and require long-term recovery).
Drinking more than 14 units of alcohol per week (1 unit =360ml beer or 45ml liquor with 40% alcohol or 150ml wine) in the 3 months before or during the screening period, alcohol cannot be banned during the hospital stay, and alcohol consumption cannot be limited to less than 2 units of alcohol per day during the post-discharge visit.
Blood donation or blood loss ≥ 300 mL within 3 months prior to screening, or blood/blood components donation planned during the trial or within 1 month after the final study visit.
Received administration of other drugs/vaccines in clinical trials within 2 months prior to screening; In other clinical trials at the time of screening;
People who diet or undergo weight loss treatment within 2 months (for whatever reason) before administration, or who have made significant changes in their lifestyle habits.;
Received vaccination within 14 days prior to screening, or have vaccination schedule during the trial, including inactivated vaccine, live attenuated vaccine, recombinant protein vaccine, recombinant adenovirus vaccine, RNA vaccine, DNA vaccine, COVID-19 vaccine;
Use medication (including prescription drugs, over-the-counter drugs, herbal medicine) with the exception of vitamin/mineral supplements, paracetamol, topical medication, and contraceptives within 14 days prior to dosing.

Any abnormal patients who met the following criteria during screening: 1) serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) exceeded the upper limit of the reference value range by 2 times; Serum total bilirubin (TBIl) exceeded 1.5 times the upper limit of the reference value range; 2) Fasting triglyceride (TG) ≥5.6mmol/L; 3) Physical examination, vital signs, electrocardiogram, laboratory examination, imaging and other abnormalities have clinical significance, and the investigator judges that they may pose a major risk to the subjects or interfere with the evaluation of safety, PK or PD results and are not suitable to participate in the trial;
Positive breath test for alcohol (>0 mg/100 mL);
Evidence of hepatitis B/hepatitis C/HIV/syphilis.
Urine screen positive for drug abuse.
Participants that refuse to stay abstinent, and refuse to consistently use a form of highly effective birth control method starting at Screening (signing the ICF) and continuing throughout the clinical study period, and to 3 months after administration of IP; or to have a birth plan during the screening period until 3 months after dosing;
Participants that plan to donate sperms from dosing until 3 months after administration of IP.
