NSAID Drug Interaction Study
This is a drug-drug interaction study in healthy volunteers to evaluate the potential pharmacokinetic (PK) effects of non-steroidal anti-inflammatory drugs on lesinurad and leinurad on the non-steroidal anti-inflammatory drugs.

- PK profile of lesinurad from plasma and urine [ Time Frame: Day 1, Day 6 (urine only), Day 7, Day 14 ] [ Designated as safety issue: No ]Profile in terms of AUC, Tmax, Cmax, and t1/2 AUC: area under the plasma concentration versus time curve; Tmax: time to maximum plasma concentration; Cmax: maximum plasma drug concentration; t1/2: apparent terminal half-life
- PK profile of naproxen and indomethacin from plasma and urine [ Time Frame: Day 1, Day 6 (urine only), Day 7, Day 14 ] [ Designated as safety issue: No ]Profile in terms of AUC, Tmax, Cmax, and t1/2
- Incidence of Adverse Events and Changes in Laboratory, Electrocardiogram, and Vital Signs Parameters [ Time Frame: 13 weeks ] [ Designated as safety issue: Yes ]

Naproxen and indomethacin are non-steroidal anti-inflammatory drugs (NSAIDs) used both prophylactically for the prevention of, and as a treatment for, acute gout flares. RDEA594-126 is an open-label study designed to assess the potential effect of multiple doses of naproxen and indomethacin on the single-dose PK of lesinurad, and to assess the potential effect of multiple doses of lesinurad on the multiple-dose PK of naproxen and indomethacin.
