Determinants of Achieving Serum Urate Goal with Treat‐to‐Target Urate‐Lowering Therapy in Gout

Arthritis RheumatolPublished Secondary analysis of a randomised trial comparing treat-to-target allopurinol and febuxostat

Authors' conclusion

Several patient-level factors were predictive of SU goal achievement among patients with gout who received treat-to-target urate-lowering therapy (ULT).

Study context

Population
Participants with gout and serum urate (SU) ≥6.8 mg/dL randomised to allopurinol or febuxostat, titrated weeks 0 to 24 and maintained weeks 25 to 48764 completing week 48
Primary endpoint
SU goal achievement: mean SU from weeks 36, 42 and 48 <6.0 mg/dL (<5 mg/dL if tophi present)
Follow-up
Weeks 36, 42 and 48
Methodological detailsmultivariable logistic regression, preselected determinants, additional analyses accounting for treatment adherence
