About this study
Official title: A Randomized, Comparative Study of HEMAX PFS® Versus EPREX/ ERYPO® in the Treatment of Anemia With Epoetin Alfa in Patients With Predialysis Chronic Kidney Disease
Phase III, multicenter, randomized, open, controlled clinical trial. A study designed as phase III, in 120 patients with chronic renal failure in the pre-dialysis stage, evaluate efficacy and safety of Hemax PFS® (PFS: prefilled syringes) vs the innovator erythropoietin alfa product (Eprex®).
Read the detailed description
This was a Phase IIIB, multicenter, randomized, open-label study to compare two products with epoetin alfa (HEMAX® PFS versus EPREX/ERYPO®).
This trial was open-label for both the patient and the investigator, but blinded in the performance of laboratory analyses.
The overall objective of the study was to evaluate the efficacy and the safety of HEMAX® PFS compared to EPREX/ERYPO®, following a dose-titration and maintenance scheme similar to the one used in the regular clinical practice.
All patients received HEMAX® PFS or EPREX/ERYPO® twice a week subcutaneously during 12 weeks of titration, switching then to an equivalent weekly dose during 12 additional maintenance weeks. During the dosing scheme switch from twice a week to once weekly, each patient continued receiving the treatment assigned at randomization.
The study conclude with n=43 patients.

| Study group | Role | What they receive |
|---|---|---|
| Eprex/Erypo | Active comparator | Receive EPREX/ ERYPO® subcutaneously with an initial dose of 29 IU/ kg twice a week (2000 IU twice a week for 70 kg of weight), to be titrated according to the scheme that is summarized below.
There will be a follow - up of patients with visits to the site every two weeks during the first 12 weeks of dose titration that will be followed by 12 additional weeks of dose maintenance with visits every 4 weeks. Receives: Biological: Erythropoietin alfa |
| Hemax PFS | Experimental | receive HEMAX® PFS subcutaneously with an initial dose of 29 IU/ kg twice a week (2000 IU twice a week for 70 kg of weight), to be titrated according to the scheme that is summarized below.

What is being measured
The primary outcome is the main question the study is designed to answer.
Efficacy Evaluation Through Change in Hemoglobin Levels
Evaluate the efficacy of treatment with erythropoietin alfa through the measured changes in levels of hemoglobin from baseline value to the mean value of the 8 to 12 weeks of treatment, comparing patients treated with HEMAX® PFS versus EPREX/ ERYPO®.
Measured: 12 weeks of treatment
Adverse Events and Adverse Reactions (Safety and Tolerability) at Weeks 12 and 24.
Evaluate the safety through the incidence of adverse events and adverse reactions asessed after 12 and 24 weeks of treatment (week 24 reported which includes those evaluated at week 12), comparing patients treated with HEMAX® PFS versus those treated with EPREX/ ERYPO®.
Measured: 24 weeks of treatment
Secondary outcomes (6)
Percentage of Responder Patients
Evaluate the efficacy of treatment with erythropoietin alfa through the percentage of responder patients (increase of Hb ≥ 1g/ dl) after 12 weeks of treatment, comparing patients treated with HEMAX® PFS versus those treated with EPREX/ ERYPO®.
Measured: 12 weeks of treatment
Percentage of Patients That Required Any Transfusion
Evaluate the percentage of transfusional requirements after 12 weeks of treatment, comparing patients treated with HEMAX PFS versus those treated with EPREX/ ERYPO®.
Measured: 12 weeks of treatment
Change of Hemoglobin Level at Week 12 of Treatment
Evaluate the efficacy between arms (HEMAX® PFS and EPREX/ ERYPO®) of treatment with erythropoietin alfa through the change in the level of hemoglobin from baseline in every visit until the week 12 visit.
Measured: Intragroup efficacy until week 12
Evaluate the Efficacy Between Arms 24 Weeks: Week Doses in the Titration
Evaluate the efficacy between arms (HEMAX® PFS and EPREX/ ERYPO®) of the change from the twice - a - week doses in the titration phase to a weekly dose in the maintenance phase through the changes in the hemoglobin levels from week 12 to weeks 16, 20 and 24 of treatment
Measured: Intragroup efficacy until week 24
Incidence of Anti-drug Antibodies (Immunogenicity)
An anti-erythropoietin alfa antibody determination will be performed to evaluate treatment immunogenicity at week 12 and 24 visit
Measured: 12 and 24 weeks of treatment
Concentration of Hepcidin
Hepcidin will be analyzed by ELISA at baseline, week 12 and 24 in order to evaluate the treatment response.
Measured: 24 weeks of treatment

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 13 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 20 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in Argentina, Paraguay. 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?
Yes. Results are posted in the registry (first posted 20 Mar 2025). 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?
Efficacy Evaluation Through Change in Hemoglobin Levels (time frame: 12 weeks of treatment). The study lists 2 primary outcomes in all. 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 20 Mar 2025.
