About this study

Official title: Intravenous Ferric Carboxymaltose (Ferinject®) With or Without Erythropoietin for the Correction of Preoperative Anaemia in Patients Undergoing Orthopaedic Surgery

Study Design: Single-centre, block randomised, blinded, controlled, phase IIIb, parallel group pilot study.

Primary Objective:

Read more
  • To evaluate the effect of the administration of ferric carboxymaltose (Ferinject®) with or without erythropoietin vs. no treatment (standard therapy) on the preoperative anaemia status in patients undergoing orthopaedic surgery

Secondary Objective:

  • To gain informations for the design of a possible follow-up study
  • To evaluate the effect of the administration of ferric carboxymaltose (Ferinject®) with or without erythropoietin vs. no treatment (standard therapy) on pre- and postoperative Hb levels, iron status, transfusion rate, days until discharge.
  • To evaluate the tolerability and safety of Ferinject®

Study Centres:

This is a single centre study

Patients:

A total of 75 completed patients (50 patients in the intravenous iron treatment groups and 25 patients in the no treatment group will be recruited.

Read the detailed description

TREATMENT:

Patients will be randomised 1:1:1 to one of the following groups:

Group I - Ferinject ® and EPO treatment group 25 patients will be randomised to the Ferinject and EPO treatment group.

For each patient, the cumulative total iron requirement will be calculated using the formula of Ganzoni [Ganzoni et al, 1970]:

Iron deficit [mg] = b.w. [kg]† x (target Hb - actual Hb) [g/L] x 0.24†† + depot iron [mg]

† In patients with a body mass index (BMI = weight [kg] / (height [m] x height [m])) >25, a normalised weight will be used to calculate the iron deficit. Normalised weight [kg] = 25 x height [m] x height [m].

†† Factor 0.24 = 0.0034 (iron content Hb = 0.34%) * 0.07 (blood volume = 7% of b.w.) * 1000 (conversion g to mg) Target Hb: 150 g/L Actual Hb: Value obtained at screening visit Depot iron: 500 mg

Patients will receive a first dose of 1000 mg iron as Ferinject® 21 days prior to the scheduled surgery. Patients will receive Ferinject® once weekly for up to two occasions (Day -21 and Day -14) until the calculated cumulative dose is reached for that individual. The Day -14 infusion may not be necessary, depending on the calculated total iron requirement for each patient. Patients in treatment group 1 will get additionally a single 10000 IU dose of EPO together on treatment day -14.

Group II - Ferinject ® treatment group 25 patients will be randomised to the Ferinject without EPO.

For each patient, the cumulative total iron requirement will be calculated using the formula of Ganzoni [Ganzoni et al, 1970]:

Iron deficit [mg] = b.w. [kg]† x (target Hb - actual Hb) [g/L] x 0.24†† + depot iron [mg]

† In patients with a body mass index (BMI = weight [kg] / (height [m] x height [m])) >25, a normalised weight will be used to calculate the iron deficit. Normalised weight [kg] = 25 x height [m] x height [m].

†† Factor 0.24 = 0.0034 (iron content Hb = 0.34%) * 0.07 (blood volume = 7% of b.w.) *1000 (conversion g to mg) Target Hb: 150 g/L Actual Hb: Value obtained at screening visit Depot iron: 500 mg

Patients will receive a first dose of 1000 mg iron as Ferinject 21 days prior to the scheduled surgery. Patients will receive Ferinject® once weekly for up to two occasions (Day -21 and Day -14) until the calculated cumulative dose is reached for that individual. The Day -14 infusion may not be necessary, depending on the calculated total iron requirement for each patient.

Group III - Control group 25 patients will receive the standard treatment for this patient population (no anaemia treatment).

Primary Efficacy Endpoints

  • Hb increase from baseline till day of surgery

Secondary Efficacy Endpoints

  • Percentage of patients reaching an Hb of > 12 g/dl (women) or of > 13 g/dl (men) at any point in time during the study
  • Change in Hb level from baseline to highest Hb level during the study
  • Change in Ferritin value from baseline to highest ferritin value during the study
  • Change in Tsat value from baseline to highest Tsat value during the study
  • Transfusion rate
  • Infection rate
  • Days until discharge from hospital
  • Days until rehabilitation therapy

Secondary Safety Endpoints:

  • Adverse events: type, nature, incidence and outcome
  • Vital signs (temperature, blood pressure and heart rate)
  • Clinical laboratory panels (haematology/coagulation, clinical chemistry, except Hb and iron status, which are considered to be efficacy endpoints)

Laboratory parameters:

Hematology/coagulation parameters to be analysed are Hb, haematocrit (Hct), red blood cell count (RBC), white blood cell count (WBC) with differential and platelet count, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC).

Clinical chemistry parameters to be analysed are alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), C-reactive protein (CRP), endogenous erythropoietin.

Iron status parameters include serum iron, serum ferritin, serum transferrin and TSAT.

Additional parameters - folic acid, vitamin B12 and beta-HCG will be analysed at baseline only, creatinin, soluble transferrin receptor and total bilirubin will be analysed at all visits.

Statistical Methods:

Summary statistics will be provided for safety and efficacy parameters as well as for the patients' demographic characteristics. Data will be presented per visit, if appropriate. The test for the primary endpoint is confirmative. Statistical tests of secondary endpoints will be employed for exploratory purposes to highlight interesting comparisons (e.g., baseline versus end of study) that may warrant further consideration. Unless otherwise specified, the significance level of all statistical tests will be 5% with a two-sided alternative. If appropriate, corresponding 95%-confidence intervals will be calculated. The sample size estimation is based on t-test calculation.

Continuous variables will be summarized as mean +/- SD and median with range where appropriate. Continuous variables will be compared using the Kruskal-Wallis test followed by pairwise Mann-Whitney tests with Bonferroni-correction. Nominal variables will be compared using the chi-square test or Fisher's exact test where appropriate. Changes within groups of nominal variables will be analyzed using McNemar test.

Changes within groups of continuous variables will be analyzed using the Friedman test followed by pairwise post hoc comparisons using the Wilcoxon signed rank test with Bonferroni correction. Prevalence of anaemia will be presented with exact confidence interval (CI). Continuous variables will be transformed to normal distribution, and CIs for the mean will be computed. The limits of these CIs then will be retransformed to the original units and interpreted as CIs for the median.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ferinject ® in people with Iron Deficiency Anemia, run by University of Zurich at 1 site in Switzerland.

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 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: stopped early, as of the sponsor's last update on 20 Jun 2013. 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 Switzerland. 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. Some participants in this study may receive a placebo. 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?

The study was stopped early (reason given: Not being able to recuit sufficient patients due to a lack of complience). 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?

Hb increase from baseline till day of surgery (time frame: 6 weeks). 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 Jun 2013.
