  • Subject has a QT interval corrected for heart rate according to Fridericia's formula > 450 msec during the Screening Period, confirmed by a repeat assessment.
  • Subject has uncontrolled hypertension.
  • Subject has an estimated creatinine clearance < 60 mL/min.
  • Subject has an alkaline phosphatase > 2.0 x upper limit of normal during the Screening Period.
  • Subject has active liver disease or impaired hepatic function.
  • Subject is receiving chronic treatment with more than 325 mg salicylates per day.
  • Subject has a medical condition that requires or may require systemic immunosuppressive (eg, chronic low-dose oral prednisone) or immunomodulatory treatment.
  • Subject is unable to take colchicine for gout flare prophylaxis.
  • Subject is receiving strong or moderate CYP3A inhibitors, p-glycoprotein inhibitors, or digoxin.
  • Subject received any strong enzyme- inducing drug or product (eg, rifampin, rifabutin, phenytoin, phenobarbital, St. John's Wort) within 2 months prior to Day 1 or refuses to refrain from taking these medications until the end of the study.

5. Study Description

Brief Summary
This study will assess the serum uric acid lowering effects and safety of 3 dose levels of RDEA3170 compared to placebo in subjects with gout.
Detailed Description
This monotherapy study is the initial Phase 2 study for RDEA3170 and is designed to compare the safety and efficacy of multiple dose levels of RDEA3170 with placebo when given for up to 24 weeks to subjects with gout. The placebo control for RDEA3170 is included in this study to minimize bias in study assessments and monitoring. Further, to accomplish the goal of understanding the safety profile of RDEA3170, it is important to compare RDEA3170 monotherapy with placebo for at least 24 weeks.
