Had≥2 gout flares within 1 year prior to the first administration of Firsekibart； 5. Willing to comply with the protocol-defined urate-lowering therapy (ULT) during the study, meeting one of the following conditions: * Patients currently receiving ULT with a stable regimen for≥14 days may continue their stable dosing; adjustments (including medication switch, dose reduction, or discontinuation) are permitted if the investigator assesses intolerance, poor efficacy, or achievement of target serum uric acid levels; * For patients not on ULT or those on ULT but not stable for 14 days before enrollment, the investigator will decide whether to initiate ULT based on uric acid levels. In principle, allopurinol-naive patients should not be prescribed allopurinol in this study; 6. Voluntarily signed the Informed Consent Form (ICF). Exclusion Criteria: 1. History of hypersensitivity to the study drug or similar classes of drugs; 2. Systemic treatment with corticosteroids, or use of colchicine/NSAIDs within 24 weeks prior to enrollment; 3.

Confirmed active tuberculosis infection; 13. Receiving renal dialysis; 14. Laboratory abnormalities at screening as follows: White blood cellcount or absolute neutrophil count below the lower limit of normal at the study site; Platelet count ≤100×10\^9/L; Total bilirubin \> 1.5 times ULN (Upper Limit of Normal); AST/ALT \> 3 times ULN; Estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73m²; Triglycerides \> 5.7 mmol/L; 15. Pregnant or breastfeeding women; 16. Women of childbearing potential who refuse to use highly effective contraception during the study; 17.
