Rescue therapy is defined as RBC transfusion for all subjects or ESA for subjects treated with roxadustat.; Time-to-first adjudicated cardiovascular events [ Time Frame: Throughout study, with study duration up to 4 years ]Analyses of the adjudicated events are described in a separate pooled statistical analysis plan.
Original Primary Outcome Measures ICMJE; (submitted: June 24, 2014)	Major adverse cardiovascular (CV) events (MACE): Time to first occurrence of death from any cause, non-fatal myocardial infarction or non-fatal stroke. [ Time Frame: From randomization (~week 6) to end of study (event-driven, anticipate 1-2 years). ]; Time from randomization to the first occurence of any of the components of the primary composit endpoint.

Measured at randomization (~week 6) to end of study (event-driven, anticipate 1-2 years). [ Time Frame: From randomization (~week 6) to end of study (event-driven, anticipate 1-2 years). ]To evaluate the safety and tolerability of Roxadustat.
