Population: Safety Population: all randomized participants who received at least 1 dose of lesinurad or placebo.

Kidney function was monitored throughout the study by measuring sCr and calculating eCrCl by Cockcroft-Gault formula using ideal body weight. Treatment discontinuations were required if a participant experienced an absolute sCr ≥4.0 mg/dL or an eCrCl \<20 mL/min (based on central laboratory results).

Timeframe: From first dose of study drug through each participant's study duration, up to approximately 18 months.

Population: All Randomized Participants

Renal-related and kidney stone events were based on Medical Dictionary for Regulatory Activities (MedDRA) "Renal and Urinary Disorders" system organ classification. AEs that started on or after the first dose of study drug in this study, or those AEs with onset prior to the first dose of study drug but worsened after the first dose of study drug, were considered treatment emergent.
