• Current or have a history of serious cardiovascular disease and surgical history
• Current underlying liver disease or history of liver disease, as assessed by the investigator, that may affect the safety assessment of the drug
• Renal disease in adult and the slope of kidney >5 mL/min/1.73m²/year
• Subjects with poorly controlled diabetes after drug treatment (e.g., HbA1c≥8%);
• Acute/chronic infection or other chronic disease that the investigator determines will increase the risk of participants participating in the study

• Patients with a history of drug use or drug abuse or alcoholism
• Use of systemic (intravenous or oral) immunomodulators within the past 6 months or currently
• Initiation of treatment with blood pressure lowering drugs that affect proteinuria levels (such as angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, or angiotensin-receptor/enkephalin inhibitors) within 4 weeks prior to screening, or changes in the therapeutic dose of these drugs within 4 weeks prior to screening;
• Has received, or is currently receiving, a clinical trial of another investigational drug/medical device or treatment (other than vitamins and minerals) within 3 months prior to signing the informed consent (or within 5 half-lives of the investigational drug, whichever is longer)
• Previous treatment with gene therapy products
• Those who had received live attenuated vaccine/vaccine within 12 weeks prior to screening or planned to receive it during the study
