Outcome Measures

Primary Outcome Measures :
  1. Mean change in Hb between Baseline and the primary evaluation period [ Time Frame: Baseline visit, Week 36 ]
  2. Major adverse cardiovascular events (MACE), defined as all-cause mortality, non-fatal myocardial infarction, or non-fatal stroke [ Time Frame: from Baseline visit to end of study (event-driven, minimum 1 year) ]

Secondary Outcome Measures :
  1. Mean change in Hb value between Baseline and the secondary evaluation period [ Time Frame: Baseline visit, Week 52 ]
  2. Proportion of subjects with Hb values within the target range during the primary evaluation period [ Time Frame: Baseline visit, Week 36 ]
  3. AEs and SAEs [ Time Frame: from Baseline visit to end of study (event-driven, minimum 1 year) ]
  4. Proportion of time with Hb values within the target range during the primary evaluation period [ Time Frame: Baseline visit, Week 36 ]
  5. Proportion of time with Hb values within the target range during the secondary evaluation period [ Time Frame: Baseline visit, Week 52 ]
  6. Proportion of subjects with Hb values within the target range during the secondary evaluation period [ Time Frame: Baseline visit, Week 52 ]
  7. Proportion of subjects with Hb increase of >1.0 g/dL from Baseline visit [ Time Frame: From baseline visit to end of study (event-driven, minimum 36 weeks) ]
  8. Time to achieve Hb incrase of >1.0 g/dL from Baseline visit [ Time Frame: From baseline visit to end of study (event-driven, minimum 36 weeks) ]
  9. Mean change in Hb between Baseline (mean pretreatment Hb) and the primary evaluation period (mean Hb from Weeks 24-36 stratified by pre-baseline ESA exposure [ Time Frame: Baseline visit, Week 36 ]
  10. Proportion of subjects receiving IV iron therapy [ Time Frame: Baseline visit, Week 52 ]
  11. Mean monthly dose of IV elemental iron administered in subjects who have received IV iron [ Time Frame: Baseline visit, Week 52 ]
  12. Proportion of subjects receiving RBC transfusion(s) [ Time Frame: Baseline visit, Week 52 ]
