Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43857   clinical trials with a EudraCT protocol, of which   7284   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    General information about the trial
    Main objective of the trial
    The primary efficacy objective of the study was to demonstrate that IV iron isomaltoside 1000 is superior compared to placebo in leading to a less decrease in the Hb level in non-anaemic patients undergoing cardiac surgery.
    Protection of trial subjects
    The protocol and amendments were approved by local ethics committees/Institutional Review Boards and competent authorities. The trial was conducted in accordance with good clinical practice and the Declaration of Helsinki. Informed consent was obtained in writing prior to any trial-related activities.

    Recruitment
    Recruitment details
    Subjects were screened in the period 13 December 2012 to 01 July 2013. The trial took place at one site in Denmark.

    Pre-assignment
    Screening details
    Subjects ≥ 18 years of age undergoing elective or sub-acute CABG, valve replacement, or a combination thereof, with a Hb ≥ 12.0 g/dL (7.45 mmol/L) for women and a Hb ≥ 13.0 g/dL (8.1 mmol/L) for men, and who were willing to provide written informed consent were considered eligible to participate in the trial.

    Subject, Investigator
    Blinding implementation details
    The study drug was administered while the patient was in anaesthesia in order to keep the patient blinded.

    Statistical analysis description
    An ANCOVA model was used to compare the average change in Hb concentration from baseline to week 4. The number of subjects may differ from the analysis population if data is missing. The sample size calculation was based on superiority analysis, normally distributed data, Type I error = 5 %, 2-sided test, and a power of 80 %. With a sample size of 30 patients/treatment group and an assumed standard deviation of 1.50, the trial was able to detect a difference of 1.1 g/dL in change in Hb.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    18 Aug 2011
    • In the inclusion criterion no. 3, the Hb level for women was changed from “< 12.0 g/dL (7.3 mmol/L)” to “< 11.5 g/dL (7.1 mmol/L)” • Impaired renal function was added as exclusion criteria no. 15 • Stratification by diagnostic group and baseline Hb level was added to the randomisation procedure • Blood transfusion was added to the list of protocol deviations, however patients requiring blood transfusion would not be withdrawn from the study • Dosing was to be done at the time of surgery when the patient was under anaesthesia to ensure blinding • Mean corpuscular Hb, globulin, and albumin:globulin ratio were deleted from the list of laboratory assessments • “Natriumklorid” was specifically mentioned as the placebo used for reference therapy • List of concomitant medications administered as part of the standard procedure in patients undergoing elective or sub-acute CABG, valve replacement, or a combination were added as Appendix 2 • List of AEs known to occur during surgery or postoperatively after the cardiac surgery were added as Appendix 3
    20 Dec 2011
    • Secondary objectives were added in accordance to the secondary endpoints • Secondary endpoint no. 6 was modified from number of patients in each randomisa-tion group who experience any “Suspected Unexpected Serious Adverse Event (SU-SAR)” to “study drug related adverse events (AEs/SAEs/SUSARs)” • Description of body measurements and six minute walking distance test was added to the study assessments • Analysis of laboratory parameters was to be conducted at the “local laboratory” in-stead of the “central laboratory” • Unblinding was to performed by the study nurse at the Department of Cardiothoracic Surgery • The safety reporting and study management sections were modified to reflect that Pharmacosmos A/S was the sponsor of the study and MNI was the sponsor designee for pharmacovigilance • Safety review by safety review committee was added • Time points for efficacy assessments were mentioned as: at baseline, 4 weeks, and 3 months postoperatively • Statistical methods for analyses of the number of patients who need blood transfusion, number of postoperative days to discharge, and change in six-minute walking distance from baseline to 4 weeks postoperatively were added • Role and responsibility of the investigator during an audit was added
    15 Nov 2012
    • The study population was changed from anaemic to non-anaemic • Dose of iron isomaltoside 1000 was changed from “20 mg/kg” to “1000 mg” • Addition and deletion of secondary endpoints. Two secondary endpoints “proportion of patients that are anaemic (women < 12 g/dL and men < 13 g/dL) at day 5 and week 4” and “proportion of patients able to maintain Hb between 9.5 and 12.5 g/dL (both values included) at day 5 and week 4” were added, and the endpoint “change in Hb concentrations from baseline (preoperatively – the day before surgery or same day) to 3 months postoperatively” was deleted • The secondary endpoint “change of reticulocytes from baseline” was changed from 4 weeks and 3 months to day 5 and week 4 • Duration of the study for each individual patient was changed from “3 months” to “4 weeks” • Inclusion criterion 3 was revised where Hb level for women was changed from “< 11.5 g/dL (7.1 mmol/L)” to “≥ 12.0 g/dL (7.45 mmol/L)” and from “< 13.0 g/dL (8.1 mmol/L)” to “≥ 13.0 g/dL (8.1 mmol/L)” for men • Additional exclusion criterion “patients receiving blood transfusion < 30 days before screening and/or during the elective or sub-acute CABG, valve replacement, or a com-bination thereof” was added • Minor revisions in statistical analyses section were done, including revision of the def-inition of PP population and the number of randomised patients were changed from “80” to “60”
    21 Mar 2013
    • Six minute walking distance was replaced by NYHA classification • Instead of analysis of co-variance model, chi-square test was used to compare the average change in NYHA classification
