Body mass index (BMI) of 19.0-32.0 kg\u002Fm² (inclusive) at screening; body weight ≥ 50 kg for male participants and ≥ 45 kg for female participants.\n4. Absolute estimated glomerular filtration rate (eGFR), calculated using the CKD-EPI 2021 equation during the screening period, falls into the corresponding group as follows:\n\n   Normal renal function: absolute eGFR ≥ 90 mL\u002Fmin; Mild renal impairment: 60 mL\u002Fmin ≤ absolute eGFR \\\u003C 90 mL\u002Fmin; Moderate renal impairment: 30 mL\u002Fmin ≤ absolute eGFR \\\u003C 60 mL\u002Fmin.\n5. Female participants of childbearing potential must have a negative serum pregnancy test during the screening period. Highly effective contraception must be used from signing the informed consent form until 6 months after the last dose of the study drug, by the participant and their partner of childbearing potential.\n\nExclusion Criteria:\n\n1. At screening, chest radiography demonstrates clinically significant abnormalities.\n2. Any of the following abnormal laboratory test results at screening:\n\n   Total bilirubin \\> 1.5 × upper limit of normal (ULN); ALT or AST \\> 2 × ULN; International normalized ratio (INR) \\> 2 or any clinically significant abnormality; QTcF ≥ 450 ms in males or QTcF ≥ 470 ms in females (QTc interval must be heart rate-corrected using the Fridericia formula); Other abnormal laboratory test results deemed clinically significant by the investigator.\n3. Positive test results for hepatitis B surface antigen, hepatitis C virus antibody, human immunodeficiency virus antibody, or Treponema pallidum antibody at screening.\n4. Participants with primary or secondary IgA nephropathy (patients with IgA nephropathy are advised to be screened for the Phase IIa study of the investigational product).\n5. Current diagnosis of tuberculosis (TB); history of active TB with cure \\\u003C 5 years prior to screening; or high likelihood of TB infection as judged by the investigator based on comprehensive TB screening during the screening period.\n6. Presence or suspected presence of other active viral, bacterial, fungal, or parasitic infections within 4 weeks before screening.\n7. History of epidemic meningococcal infection, or other recurrent or chronic infections.\n8. History of splenectomy or asplenia.\n9. History of complement abnormalities or hereditary complement deficiency.\n10. Development of acute kidney injury within 2 weeks before screening.\n11.
