What participants receive

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

  • Pure Red Cell Aplasia diagnostic confirmationProcedure or surgery

    Patients who meet the appropriate criteria in the selection period will be subject to Pure Red Cell Aplasia diagnostic confirmation by collecting 20 mL of blood in dialysis units.

    The samples will be processed, aliquoted and transported to Bio-Manguinhos, where depart periodically (according to the volume of samples) to the reference laboratory Sce Immunologie et d'Hématologie biologiques Hôpital Saint Antoine, where the dosage of antibody will be held anti epoetin alfa

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Pure Red Cell Aplasia diagnostic confirmation in people with Red-Cell Aplasia, Pure and Renal Insufficiency, Chronic, run by The Immunobiological Technology Institute (Bio-Manguinhos) / Oswaldo Cruz Foundation (Fiocruz).

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 3 inclusion and 15 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: status not confirmed, as of the sponsor's last update on 6 Jan 2016. 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?

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?

Number of Participants With Hyporesponsiveness to EPO related to anti-alfa epoetin antibodies. (time frame: 3 years). 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 6 Jan 2016.
