Participant Flow

Two centers took part in this study between 15 July 2008 and 21 November 2008.

Subjects were enrolled into treatment groups (healthy subjects, mild, moderate, severe renal impairment, or end stage renal impairment on hemodialysis) based on creatinine clearance results obtained closest to the dosing date at screening as determined by the Cockcroft-Gault equation (with the exception of subjects undergoing hemodialysis).
