What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT00526747
Study groupRoleWhat they receive
Epo-resistantPatients with CKD (estimated GFR < 60cc/min) not on hemodialysis who are receiving greater than or equal to 100IU/kg/week of epoetin alpha and/or 1mcg/kg/week darbepoetin to obtain target hemoglobin or hematocrit.
Epo-responsivePatients with CKD (estimated GFR < 60cc/min) not on hemodialysis who are requiring <100IU/kg/week of epoetin alpha and/or 1mcg/kg/week of darbepoetin to obtain target hemoglobin/hematocrit.

Questions about this trial

What is this clinical trial studying?

An observational study of Anemia and Kidney Failure, run by Duke University at 2 sites in United States.

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 1 inclusion and 9 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 11 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00526747, which also lists 21 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 11 Apr 2013.
