About this study

Official title: A Randomized, Controlled Trial of Costs Associated With Anemia Therapy in Hemodialysis Patients Treated With Intravenous Darbepoetin Alfa Versus Epoetin Alfa

The purpose of this study is to determine if there is a cost difference between darbepoetin alfa and epoetin alfa when used intravenously to treat anemia in hemodialysis patients.

Read the detailed description

Eligible hemodialysis patients who are currently receiving an erythropoiesis stimulating agent (ESA) who enrol and sign consent will be randomized on a 1:1 basis to either remain on epoetin alfa or switch to darbepoetin alfa as their anemia therapy. Patients will be dosed with the assigned drug using a study algorithm to maintain their hemoglobin (Hb) level within the currently recommended range (100-120 g/L). There will be an initial "run in" period of a minimum of six weeks to ensure the patient's hemoglobin is stable within the target range. The trial itself will run for a subsequent twelve months (active phase). Every effort will be made to ensure that Hb stays within the target range during the study period. The primary outcome will be the total cost of each ESA therapy over the twelve month active phase. Data including Hgb, iron indices and dosing, and clinical events will be obtained from electronic sources and from the attending physicians and/or the clinical pharmacist.

What participants receive

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

  • Epoetin AlfaDrug

    Also called Eprex

    The investigator will adjust epoetin doses as per the study algorithm during the run-in (every two weeks) and active phases (every four weeks). This will continue until the 12 month active phase is complete or the patient is withdrawn from the study.

    All epoetin will be administered intravenously through a hemodialysis machine port using a manufacturer-provided pre-filled syringe.

    It is not anticipated that a subject will require a dose of epoetin > 30 000 units weekly. If this occurs the dose will not be escalated any higher. Such a patient would likely meet the criteria for study withdrawal.

    Intravenous iron will be given as per the study algorithm and only one formulation of iron is used, sodium ferric gluconate.

  • Darbepoetin alfaDrug

    Also called Aranesp

    The investigator will adjust darbepoetin doses as per the study algorithm during the run-in (every two weeks) and active phases(every four weeks). This will continue until the 12 month active phase is complete or the patient is withdrawn from the study.

    All darbepoetin will be administered intravenously through a hemodialysis machine port using a manufacturer-provided pre-filled syringe.

    It is not anticipated that a subject will require a dose of darbepoetin >150µg weekly. If this occurs the dose will not be escalated any higher. Such a patient would likely meet the criteria for study withdrawal.

    Intravenous iron will be given as per the study algorithm and only one formulation of iron is used, sodium ferric gluconate.

Study groups in NCT02817555
Study groupRoleWhat they receive
Epoetin alfaActive comparatorPatients who are enrolled and randomized to the Epoetin arm will remain on their current dose and frequency. After the first hemoglobin (Hb) measurement the study algorithm will be used to guide anemia management. The subjects in this arm will remain on epoetin for the required run-in phase followed by the 12 month active phase.
Receives: Drug: Epoetin Alfa
Darbepoetin alfaActive comparatorPatients who are enrolled and randomized to the Darbepoetin arm will have their epoetin discontinued at the end of the week preceding entry into the study and will switch to darbepoetin on the date that they would normally be receiving their next dose of epoetin. Switching patients to darbepoetin will be done using the conversion ratio of 200 units of epoetin to 1 μg of darbepoetin as used per week, rounded up or down to the nearest available pre-filled syringe dose available from the manufacturer. After the first Hb measurement the study algorithm will be used to guide anemia management. The subjects in this arm will remain on darbepoetin for the required run-in phase followed by the 12 month active phase.
Receives: Drug: Darbepoetin alfa

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Epoetin Alfa and Darbepoetin alfa in people with Anemia and Chronic Kidney Disease, run by Andrea L Woodland.

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 5 inclusion and 14 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 10 Sep 2019. 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?

Yes. Results are posted in the registry (first posted 10 Sep 2019). 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?

Cost of Erythropoiesis Stimulating Agent (time frame: 12 months). 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 NCT02817555, which also lists 2 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 10 Sep 2019; AzTrials last refreshed its copy on 8 Nov 2026.
