Prior treatment

• Within 4 weeks before screening, the following drugs could not maintain the stable regimen: diabetes drugs, hypertension drugs, non-steroidal anti-inflammatory drugs;
• If glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are prescribed, the dose are unstable within 8 weeks before screening ;
• Received any other study drug treatment within 30 days or 5 half-lives (whichever is longer) prior to screening;
• Acute kidney injury or dialysis treatment within 6 months before screening;
• Received kidney transplant, or plan to receive kidney transplant during the trial;

Other illness

• A known or suspected allergy to the investigational medical drug or its components or excipients;
