About this study
Official title: Efficacy and Safety of Epoetin Omega in Patients Undergoing Regular Dialysis. Part II: Comparative Trial Versus Epoetin Alfa
The two epoetins, Epoetin alfa, a well established drug to treat renal anemia and Epoetin Omega, that differs from Epoetin alfa in the sugar moiety of the molecule were compared in regard of efficacy and safety to treat end stage renal disease anemia. Study hypothesis was that Epoetin Omega is non-inferior to Epoetin alfa in correcting renal anemia in dialysis patients. A 12-weeks randomized comparative efficacy study was performed including 77 end stage renal disease patients (epoetin omega:n=39, epoetin alfa: n=38). In the intent-to-treat analysis, average weekly difference in hemoglobin versus baseline value was higher in omega-treated patients: 1.94+-0.81 vs. 1.23+-0.62 g/dl. The unadjusted and adjusted omega-alfa differences were 0.71 g/dl (95%CI 0.38 to 1.04; p<0.001) and 0.78 g/dl (0.49 to 1.08;p<0.001), respectively. Average weekly epoetin dose was lower in the omega group: 87+-25 vs. 108+-21 IU/kg. The unadjusted and adjusted omega-alfa differences were -21IU/kg (-32 to -11; p<0.001) and -24IU/kg (-35 to -13; p<0.001), respectively. Epoetins were comparably well tolerated. In dialysis patients, subcutaneous epoetin omega apparently provides a greater anti-anemic effect per administered dose (IU) than epoetin alfa.

A 12-weeks randomized comparative efficacy study was performed including 77 end stage renal disease patients (epoetin omega:n=39, epoetin alfa: n=38). All patients were anemic (Hemoglobin < 90 g/L), treated by regular hemodialysis and without signs of bleeding, hemolysis, inflammation or history of major surgery.Treatment was started with 50 IU/kg body weight subcutaneously per week and thereafter adjusted according to the hemoglobin response. In the intent-to-treat analysis, average weekly difference in hemoglobin versus baseline value was higher in omega-treated patients: 1.94+-0.81 vs. 1.23+-0.62 g/dl. The unadjusted and adjusted omega-alfa differences were 0.71 g/dl (95%CI 0.38 to 1.04; p<0.001) and 0.78 g/dl (0.49 to 1.08;p<0.001), respectively.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Epoetin in people with End Stage Renal Disease and Renal Anemia, run by General Hospital Sveti Duh at 1 site in Croatia.
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 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: finished, as of the sponsor's last update on 21 Jul 2006. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Croatia. 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.
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?
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.
What does the primary outcome measure?
Hemoglobin level. 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 NCT00322413, 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 21 Jul 2006.
