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
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The proportion of subjects with sUA levels <6.0 mg/dL sustained at months 4, 5, and 6 | Up to Month 6 | Serum uric acid (sUA) level will be measured at Month 4,5, and 6 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The proportion of subjects with sUA levels <5.0 mg/dL sustained at months 4, 5, and 6 | Up to Month 6 | Serum uric acid (sUA) level will be measured at Month 4,5, and 6 |
| The proportion of subjects reporting a gout flare up to each visit. | Up to Month 6 | Gout flare (intense pain, swelling, or/and tenderness in the joint area) will be assessed from baseline up to 6 months |
| Incidence rate of adverse event | Up to Month 6 | Safety assessment |
