Tigulixostat (IBI128) vs Febuxostat in Gout
Sponsor:

Innovent Biologics Technology Limited (Shanghai R&D Center)

Brief Summary:

The primary purpose of this study is to compare the efficacy of Tigulixostat (IBI128) versus Febuxostat on the proportion of Chinese adults with gout achieving a serum uric acid (sUA) level \< 360 μmol/L at Week 24. The study also evaluates safety, gout attacks, kidney function, inflammation, and quality of life over 52 weeks of treatment. Approximately 600 eligible participants will be randomized to receive either Tigulixostat or Febuxostat.

    • 3. Diagnosed with gout according to the 2015 ACR/EULAR classification criteria.
    • 4. Serum uric acid (sUA) at screening
      • ≥ 480 μmol/L for subjects without comorbidities;
      • ≥ 420 μmol/L for subjects with at least one concurrent condition (e.g., ≥ 2 gout attacks/year, tophi, chronic gouty arthritis, hypertension, diabetes, dyslipidemia, age of onset \< 40 years).
      • 5. Voluntarily sign the informed consent form and agree to strictly follow the protocol requirements.
      Exclusion Criteria
    • Participants who meet any of the following criteria will be excluded from the study
      • 1. History of allergy or intolerance to any component of febuxostat or Tigulixostat, or previous evidence of poor response to febuxostat treatment (e.g., sUA \> 420 μmol/L after ≥ 6 weeks of febuxostat ≥ 40 mg).
      • 2. Acute gout attack within 4 weeks prior to screening or from screening to first dose.
      • 3. Use of uric acid-lowering drugs (e.g., allopurinol, febuxostat, probenecid, benzbromarone, dotinurad, recombinant uricase; excluding sodium bicarbonate) within 2 weeks before screening.
      • 4. Hyperuricemia caused by secondary gout (e.g., myeloproliferative disease, tumor, organ transplantation, enzyme deficiency, renal tubular dysfunction, lead poisoning, psoriasis, medications), excluding hyperuricemia due to renal insufficiency.
      • 5. Use of the following medications or therapies prior to screening or planned during the study
        • (1)Prior urate oxidase treatment; (2)Concomitant medications affecting uric acid levels within 4 weeks before screening with dose adjustments (e.g., losartan, calcium channel blockers, diuretics, fenofibrate, atorvastatin, α-glucosidase inhibitors, insulin sensitizers, DPP4 inhibitors, SGLT2 inhibitors, metformin, GLP-1 receptor agonists, pyrazinamide, aspirin); (3)Long-term drugs dependent on xanthine oxidase metabolism (e.g., azathioprine, mercaptopurine); (4)Oral corticosteroids ≥ 10 consecutive days, or intramuscular/intravenous/intra-articular corticosteroid injection within 4 weeks before screening; (5)Biologics (e.g., TNF-α inhibitors, IL-1 inhibitors, IL-6 inhibitors) within 12 weeks before screening.
        • 6\. History or evidence of any of the following diseases
          • 1. Xanthinuria, Lech-Nyhan syndrome, 5-phosphoribosyl-1-pyrophosphate synthetase superactivity, congenital myogenic hyperuricemia, rhabdomyolysis;

          • 6. Poorly controlled diabetes (HbA1c ≥ 9.0%);
          • 7. Autoimmune or inflammatory diseases requiring systemic immunosuppressive treatment;
          • 8. Active peptic ulcer or GI bleeding within 1 month;
          • 9. Diseases affecting drug absorption (e.g., IBS, IBD);
