- PK profile of metformin and furosemide from plasma [ Time Frame: Day 1 and Day 5 ] [ Designated as safety issue: No ]Profile in terms of maximum observed concentration (Cmax), time of occurence of maximum observed concentration (Tmax), area under the concentration-time curve (AUC), and apparent terminal half-life (t1/2).
- PK profile of furosemide from urine [ Time Frame: Day 1 and Day 5 ] [ Designated as safety issue: No ]Profile in terms of renal clearance (CLr) and amount of compound excreted into urine unchanged (Ae).
- Incidence of Adverse Events and Changes in Laboratory, Electrocardiogram, and Vital Signs Parameters [ Time Frame: 5 weeks ] [ Designated as safety issue: Yes ]

Leinurad is a weak in vitro inhibitor of the hepatic transporter OCT1 and the renal transporters OAT1 and OAT3 (OAT1/3). To assess the clinical relevance of these in vitro findings, this clinical study will evaluate the effect of lesinurad on the PK of metformin (OCT1 substrate) and furosemide (OAT1/3 substrate).
