Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male or female subjects between the ages of 18 85 years, inclusive.
  • Subjects with hyperuricemia and a history or presence of gout per American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2015 criteria.
  • Subjects who are currently on urate-lowering therapies (ULT) with an sUA level ≥6.0 mg/dL at screening (Visit 1); or subjects who are currently not on ULT with an sUA level ≥7.0 mg/dL at screening (Visit 1). Subjects currently on ULT will undergo washout and must have an sUA level ≥7.0 mg/dL at Visit 3 to be randomized and participate in the study.
  • Subjects with a Body Mass Index ≤50 kg/m2 and estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2 at screening (Visit 1).

Exclusion criteria

  • Subjects with secondary hyperuricemia, enzymatic defects.
  • Subjects experiencing an acute gout attack (intense pain, swelling, or/and tenderness in the joint area) within 2 weeks prior to screening (Visit 1).
  • Subjects who have received pegloticase to treat gout which has not responded to the usual treatments.
  • Subjects who have not been receiving stable doses of drugs known to affect sUA levels for the last 3 weeks prior to screening (Visit 1).
  • Subjects with a history of xanthinuria (elevated levels of xanthine in the urine) and rheumatoid arthritis
