Study Summary

This study will evaluate the potential pharmacokinetic (PK) and pharmacodynamic (PD) interaction between the XO inhibitor febuxostat and the investigational URAT1 inhibitor RDEA3170 and provide information for potential future clinical studies using this combination. Combination treatment using 2 drugs with different mechanisms of action may achieve improved response and may allow the use of lower doses, resulting in fewer side effects than the use of either drug alone.

Primary Outcome

Profile from plasma and urine in terms of AUC, Tmax, Cmax, t1/2, Ae, and CLr AUC: area under the concentration-time curve; Tmax: time to maximum plasma concentration; Cmax: maximum plasma drug concentration; t1/2: apparent terminal half-life; Ae: amount excreted of unchanged drug into urine; CLr: renal clearance

Interventions

  • DRUG placebo
  • DRUG RDEA3170 10 mg
  • DRUG Febuxostat 40 mg
