Brief summary

This study will explore the safety, tolerability, and serum uric acid lowering effect of RDEA3170 in healthy Japanese males to allow comparison with the Western population.

Detailed description

While clinical studies of RDEA3170 to date have been limited to a Western population, it is recognized that both intrinsic and extrinsic factors may impact the PK, PD, safety, and dose response in different ethnic populations. The purpose of this study is to explore the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) of single and multiple doses of RDEA3170 in healthy Japanese males, and to allow comparison of these parameters with the Western population.
