The purpose of this study is to assess the steady-state pharmacokinetics of TMC435 in participants with severe renal impairment and to compare these with the TMC435 pharmacokinetics in matched participants with normal renal function. We will also study the short-term safety and tolerability of TMC435, when administered in participants with severe renal impairment and in participants with normal renal function. Steady-state is a term that means that the drug has been given long enough so that the plasma concentrations will remain the same with each subsequent dose. TMC435 is being investigated for the treatment of chronic hepatitis C virus (HCV) infection. Pharmacokinetics (PK) means how the drug is absorbed into the bloodstream, distributed in the body, and eliminated from the body.
