- Brief Summary
The purpose of this study is to assess the impact of treatment of anemia with darbepoetin alfa to a hemoglobin target of 13 g/dL on (1) all-cause mortality and nonfatal cardiovascular events, and (2) progression to end-stage renal disease or death, in subjects with chronic kidney disease and type 2 diabetes mellitus.

- Primary Outcome Measures
Name Time Method Time to All-cause Mortality or End Stage Renal Disease (ESRD) Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to first event of all-cause mortality or ESRD. Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
Time to All-cause Mortality or Cardiovascular (CV) Events Including Hospitalization Due to Acute Myocardial Ischemia, Congestive Heart Failure (CHF), Myocardial Infarction (MI), and Cerebrovascular Accident (CVA) Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to the first confirmed composite event. Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
- Secondary Outcome Measures
Name Time Method Time to Congestive Heart Failure Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to fatal or non-fatal congestive heart failure(CHF). Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
Time to End Stage Renal Disease Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to end stage renal disease (ESRD). Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
Rate of Decline in Estimated Glomerular Filtration Rate (eGFR) Relative to Baseline Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first GFR was estimated using the following MDRD formula: 186 x \[Serum creatinine\]\^(-1.154) x \[Age\]\^(-0.203) x \[0.742 if subject is female\] x \[1.210 if subject is black\]. Change from baseline in eGFR at week 49 for each treatment group are presented. The treatment effect of the rate of decline in eGFR per year was estimated using the mixed model.
Time to All-cause Mortality Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to all-cause mortality. Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
Time to Cardiovascular Mortality Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to cardiovascular (CV) mortality. Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
Time to Myocardial Infarction Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to fatal or non-fatal myocardial infarction (MI). Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
Change in Patient Reported Fatigue Relative to Baseline at Week 25 Baseline and week 25 Change in patient reported fatigue measured by the Functional Assessment of Cancer Therapy (FACT) - Fatigue scale from baseline to week 25. Range and direction of scale: 0 = most fatigue; 52 = least fatigue
Time to Hospitalization Due to Acute Myocardial Ischemia Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to hospitalization due to acute myocardial ischemia. Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
Time to Cerebrovascular Accident Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first Time from randomization to fatal or non-fatal cerebrovascular accident (CVA). Kaplan-Meier estimate of the median time was not estimable due to low proportion of participants experiencing at least one events, therefore participants experiencing at least one event were summarized.
