Trial summary

The purpose of this study was to evaluate hemoglobin stability in subjects who had received darbepoetin alfa for a minimum of 3 months prior to study entry who were then converted to epoetin alfa at the same dosing frequency to maintain a hemoglobin level of 12 plus or minus 1 g/dL (range 11-13- g/dL).

About this study

Official title: Evaluation of Dose Conversion From Variable Dosing Intervals of Darbepoetin Alfa to Variable Dosing Intervals of Epoetin Alfa in Patients With the Anemia of Chronic Kidney Disease

The purpose of this study was to evaluate hemoglobin stability in subjects who had received darbepoetin alfa for a minimum of 3 months prior to study entry who were then converted to epoetin alfa at the same dosing frequency to maintain a hemoglobin level of 12 plus or minus 1 g/dL (range 11-13- g/dL).

Read the detailed description

This was a prospective, multicenter study in subjects with chronic kidney disease. The study was designed to address hemoglobin stability after drug conversion to epoetin alfa in subjects previously receiving darbepoetin alfa therapy.

The study was to enroll approximately 180 subjects with chronic kidney disease. Eligible subjects were those with chronic kidney disease who were receiving darbepoetin alfa every two, three, or four weeks for a period of 3 months or more and who had a stable hemoglobin (Hb) level at study entry of 12 g/dL (plus or minus 1 g/dL (11-13 g/dL). Subjects receiving darbepoetin alfa every 2, 3 or 4 weeks were switched over to epoetin alfa which they received at the same dosing frequency ( every 2, 3 or 4 weeks) upon study entry and throughout the 24 week study period. Clinical safety was assessed for the occurrence and severity of adverse events. Blood tests (Complete Blood Count, platelets, reticulocyte count, iron, were assessed at pre-determined intervals throughout the study. Vital signs (e.g. Blood pressure) were checked at each visit. Subjects received epoetin alfa at the same dosing frequency that they had previously received darbepoetin alfa. Subjects received 20,000 Units (U) epoetin alfa subcutaneously (SC) every two weeks; 30,000 U epoetin alfa SC every 3 weeks; or 40,000 U epoetin alfa SC every 4 weeks.

What is being measured

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

  1. The primary objective was to evaluate the proportion of subjects who maintained hemoglobin levels within 10% of entry levels and/or a range of 11-13 g/dL for the 24-week duration of the study.

Secondary outcomes (1)
  1. The secondary objective was to evaluate safety in subjects with chronic kidney disease throughout the study

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Epoetin alfa in people with Anemia and Chronic Renal Insufficiency, run by Ortho Biotech Products, L.P..

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 6 inclusion and 6 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: stopped early, as of the sponsor's last update on 19 May 2011. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study was stopped early (reason given: This study was stopped due to slow enrollment). Results are not available in the source record.

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?

The primary objective was to evaluate the proportion of subjects who maintained hemoglobin levels within 10% of entry levels and/or a range of 11-13 g/dL for the 24-week duration of the study.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 May 2011.
