June 17, 2020 updated by: Translational Research Center for Medical Innovation, Kobe, Hyogo, Japan

oBservational Clinical Research In Chronic Kidney Disease Patients With Renal Anemia : Renal proGnosis in Patients With Hyporesponsive Anemia To Erythropoiesis Stimulating Agents, darbepoetiN Alfa

This is an observational clinical research on patients with chronic kidney disease who are not on hemodialysis and receiving darbepoetin alfa to treat diagnosed renal anemia; the major objective is to explore novel erythropoiesis stimulating agent (ESA) response index in association with deterioration of renal function as well as occurrence of cardiovascular disease events.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Deterioration of renal function
Time Frame: For ninety six weeks after starting to administer darbepoetin alfa
For ninety six weeks after starting to administer darbepoetin alfa
Cardiovascular disease events
Time Frame: For ninety six weeks after starting to administer darbepoetin alfa
For ninety six weeks after starting to administer darbepoetin alfa

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Declination rate of estimated glomerular filtration rate(eGFR)
Time Frame: For ninety six weeks after starting to administer darbepoetin alfa
For ninety six weeks after starting to administer darbepoetin alfa
Safety assessment for every adverse event resulting from darbepoetin alfa administration
Time Frame: For ninety six weeks after starting to administer darbepoetin alfa
For ninety six weeks after starting to administer darbepoetin alfa

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Time Frame
Erythropoiesis resistance index (ERI)
Time Frame: For ninety six weeks after starting to administer darbepoetin alfa
For ninety six weeks after starting to administer darbepoetin alfa

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 1, 2014

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
