Study summary

This study will assess the potential effects of lesinurad on the pharmacokinetics (PK) of metformin and furosemide in healthy, adult male subjects.

Read the detailed description

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).

What researchers measure

Primary outcomes

  1. PK profile of metformin and furosemide from plasma

    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).

    Time frame: Day 1 and Day 5

  2. PK profile of furosemide from urine

    Profile in terms of renal clearance (CLr) and amount of compound excreted into urine unchanged (Ae).

    Time frame: Day 1 and Day 5

Secondary outcomes

  1. Incidence of Adverse Events and Changes in Laboratory, Electrocardiogram, and Vital Signs Parameters

    Time frame: 5 weeks
