About this study

Official title: A Single Arm, Open Label Study to Assess the Efficacy, Safety, and Tolerability of Once-Monthly Administration of Intravenous C.E.R.A. for the Maintenance of Haemoglobin Levels in Dialysis Patients With Chronic Renal Anaemia

This single-arm study will assess the efficacy and safety of intravenous (IV) Mircera when administered for the maintenance of hemoglobin (Hb) levels in participants with chronic renal anemia. Individuals currently receiving maintenance treatment with epoetin alfa or darbepoetin alfa will receive monthly injections of Mircera, with the starting dose (120, 200, or 360 micrograms [mcg] IV injection) derived from the dose of epoetin alfa or darbepoetin alfa they were receiving in the week preceding study start.

Being tested
Methoxy polyethylene glycol-epoetin beta

What participants receive

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

  • Methoxy polyethylene glycol-epoetin betaDrug

    Also called Mircera/CERA

    Participants will receive a starting dose of 120, 200, or 360 mcg via IV injection. Thereafter, the once-monthly dose will be titrated to achieve target Hb concentrations.

Study groups in NCT00550680
Study groupRoleWhat they receive
Mircera in Renal AnemiaExperimentalParticipants with chronic renal anemia who have been previously treated with erythropoiesis-stimulating agent (ESA) therapy will receive IV Mircera every 4 weeks for a total of 24 weeks in this single-arm study. The first dose of 120, 200, or 360 mcg will be determined by the dose of ESA received prior to administration of study treatment. Subsequent doses will be adjusted to maintain Hb concentrations within target of 10.5 and 12.5 grams per deciliter (g/dL).
Receives: Drug: Methoxy polyethylene glycol-epoetin beta

What is being measured

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

  1. Percentage of Participants Who Maintained Average Hb Within Plus/Minus (±) 1 g/dL of Reference Hb and Within Target Range During the Efficacy Evaluation Period (EEP)

    Reference Hb was determined individually per participant as the average of all Hb values during a pre-treatment stability assessment (Weeks -4 to 0). During the EEP (Weeks 17 to 24), participants provided a total of four blood samples for Hb monitoring while on treatment with Mircera/CERA. The average Hb during the EEP was calculated per participant and assessed against the reference value. The percentage of participants who had average Hb during the EEP in the target range of 10.5 to 12.5 g/dL and within ±1 g/dL of their individual reference Hb was determined as the primary endpoint. The 95 percent (%) confidence interval (CI) was calculated using the Pearson-Clopper method for exact confidence bounds.

    Measured: Weeks -4, -3, -2, -1,and 0; pre-dose (0 hours) during Weeks 18, 20, 22, and 24

Secondary outcomes (5)

  1. Mean Change in Time-Adjusted Hb From Baseline to EEP

    Reference Hb was determined individually per participant as the average of all Hb values during a pre-treatment stability assessment (Weeks -4 to 0). During the EEP (Weeks 17 to 24), participants provided a total of four blood samples for Hb monitoring while on treatment with Mircera/CERA. The average Hb during the EEP was calculated per participant and assessed against the reference value. The mean change in Hb value between reference (i.e., "Baseline") Hb and the EEP average Hb was calculated and expressed in g/dL.

    Measured: At Weeks -4, -3, -2, -1, and 0; pre-dose (0 hours) during Weeks 18, 20, 22, and 24

  2. Percentage of Participants Whose Hb Remained Within Target Range Throughout the EEP

    During the EEP (Weeks 17 to 24), participants provided a total of four blood samples for Hb monitoring while on treatment with CERA/Mircera. The percentage of participants who maintained each single Hb measurement in the target range of 10.5 to 12.5 g/dL was determined. The 95% CI was calculated using the Pearson-Clopper method for exact confidence bounds.

    Measured: Pre-dose (0 hours) during Weeks 18, 20, 22, and 24

  3. Mean Time Spent in the Target Range for Hb During the EEP

    During the EEP (Weeks 17 to 24), participants provided a total of four blood samples for Hb monitoring while on treatment with Mircera/CERA. Time spent in the target range of 10.5 to 12.5 g/dL was defined as time from first on-target Hb to time of last known on-target Hb, as collected during the EEP. Time spent in the target range was averaged among all participants and expressed in days.

    Measured: Pre-dose (0 hours) during Weeks 18, 20, 22, and 24

  4. Percentage of Participants Who Required Any Dose Adjustment of Mircera/CERA During the Dose Titration Period (DTP) and EEP

    Study drug administration occurred monthly during the DTP (Weeks 0 to 16), which began with a pre-specified dose of Mircera/CERA according to the dose of ESA administered during Week -1. Subsequent doses could be adjusted throughout the study including during the EEP (Weeks 17 to 24) on the basis of Hb levels or other modification criteria. The percentage of participants who required a dose adjustment for any reason was calculated during the DTP and EEP.

    Measured: Weeks 0, 4, 8, 12, 16, 20, and 24

  5. Number of Participants Prematurely Withdrawn From the Study to Receive Blood Transfusion

    The number of participants who were prematurely withdrawn from the study to receive a blood transfusion during treatment, including the DTP (Weeks 0 and 16) and/or EEP (Weeks 17 to 24), was reported.

    Measured: Continuously and at every visit from Week 0 (every week until Week 2, thereafter every 2 weeks) through Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Methoxy polyethylene glycol-epoetin beta in people with Chronic Renal Anemia, run by Hoffmann-La Roche at 24 sites in Greece.

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 4 inclusion and 3 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 30 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in Greece. 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 30 Mar 2016). 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?

Percentage of Participants Who Maintained Average Hb Within Plus/Minus (±) 1 g/dL of Reference Hb and Within Target Range During the Efficacy Evaluation Period (EEP) (time frame: Weeks -4, -3, -2, -1,and 0; pre-dose (0 hours) during Weeks 18, 20, 22, and 24). 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 NCT00550680, which also lists 1 linked publication.

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 30 Mar 2016.
