What is being measured

The primary outcome is the main question the study is designed to answer.

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)
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.
Measured: 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 to All-cause Mortality or End Stage Renal Disease (ESRD)
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.
Measured: Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first

Secondary outcomes (9)

Time to All-cause Mortality
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.
Measured: 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 to Cardiovascular Mortality
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.
Measured: 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 to Myocardial Infarction
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.
Measured: 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 to Cerebrovascular Accident
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.
Measured: 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 to Congestive Heart Failure
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.
Measured: 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 to End Stage Renal Disease
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.
Measured: Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first
Rate of Decline in Estimated Glomerular Filtration Rate (eGFR) Relative to Baseline
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.
Measured: Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first
Change in Patient Reported Fatigue Relative to Baseline at 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
Measured: Baseline and week 25
Time to Hospitalization Due to Acute Myocardial Ischemia
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.
Measured: Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing darbepoetin alfa in people with Kidney Disease and Diabetes Mellitus, run by Amgen.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Sep 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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) (time frame: Until a primary cardiovascular event (death, myocardial ischemia, congestive heart failure, myocardial infarction or cerebrovascular accident) occurred or 28 March 2009, whichever occurred first). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00093015, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Nov 2022.
