Participant Flow

Participants were enrolled in the study at investigative sites in China. Recruitment began in October 2009 and ended in July 2010. The study population consisted of participants with Stage 5 chronic kidney disease who were receiving hemodialysis.

If subjects were receiving vitamin D receptor (VDR) activators, they participated in a Washout Phase for 2 weeks prior to entering into the Screening Phase in order to wash out any VDR activators and their potential hysteresis or carryover effects.
