Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   38026   clinical trials with a EudraCT protocol, of which   6240   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Randomized, active-controlled, double-blind, parallel design study to evaluate the efficacy and safety of a once-a-week prophylaxis treatment with BAY79-4980 compared to three times-per-week prophylaxis with rFVIII-FS in previously treated patients with severe hemophilia A

    General information about the trial
    Main objective of the trial
    The primary objective was to evaluate the effect of a once-a-week prophylaxis regimen with BAY79-4980 on the protection from total bleeds compared to a three times-per-week prophylaxis regimen with recombinant factor VIII formulated with sucrose (rFVIII-FS).
    Protection of trial subjects
    The conduct of this clinical study met all local legal and regulatory requirements. The study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and the International Conference on Harmonization guideline E6: Good Clinical Practice. An independent Data and Safety Monitoring Board (DSMB) supervised the subjects’ safety and performed the pre-specified interim analyses according to the protocol. Before entering the study, the informed consent form was read by and explained to all subjects and/or their legally authorized representative. Participating subjects signed informed consent form and could withdraw from the study at any time without any disadvantage and without having to provide a reason for this decision. Only investigators qualified by training and experience were selected as appropriate experts to investigate the study drug. A Data and Safety Monitoring Board supervised the safety of study subjects.

    Notes
    [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
    Justification: Subjects who completed double blind treatment, were offered continuation of open label treatment and due to the early termination of the double-blind study phase, subjects who had not completed double blind treatment were offered continuation in control arm (follow up phase). Hence, the number of subjects starting the period is not consistent with the number completing the preceding period.

    Notes
    [1] - The number of subjects reported to be in the baseline period is not equal to the worldwide number of subjects enrolled in the trial. It is expected that these numbers will be the same.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    26 Feb 2008
    - The dosage for the treatment of bleeds and minor surgical interventions was limited to 1 single infusion with 35 IU/kg of BAY 79-4980 or rFVIII-POPC. The proposed treatment of bleeds and minor surgical interventions with extended dosages of BAY 79-4980 with up to 70 IU/kg/day was not accepted by a national authority. - The definition of a target joint was added. - The physical assessment of joints for the determination of the Gilbert Score was deleted at Month 6 and end of trial, as no change was expected during a 1-year observation period in subjects treated with prophylaxis. - The screening period was prolonged to from 1-3 weeks to 3-5 weeks due to logistical requirements. - Inhibitor development as reason for withdrawal was clarified. - The exclusion criterion regarding active hepatic disease was clarified.
    21 Jul 2009
    - The interim safety analysis on lipid kinetics was to be performed in a subset of 20 subjects and the interim efficacy analysis was to be performed after 100 subjects had completed 6 months of treatment. This change was due to the slow recruitment into the study. In addition, the study was extended to new countries where prophylaxis is not the treatment standard in adult hemophilia subjects. Inclusion criterion number 4 was adapted accordingly to increase the percentage of subjects on on-demand treatment. - The screening period was prolonged to 3-8 weeks due to logistic reasons. - The upper dose limit was set to 4500 IU/infusion corresponding to a body weight of 131 kg, because extreme overweight is not related to a proportional increase in distribution volume. - The endpoint related to change in joint status was deleted because no Gilbert score was determined at the end of the study. - Specification that fasting after infusion of study medication was no longer required for the lipid PK, because this has no impact on the first sample after 6 hour. Lipid values for inclusion into the lipid pharmacokinetics (PK) were defined based on American Heart Association’s Adult Treatment Panel (AHA-ATP) III recommendations. - For the repeat FVIII PK at Week 26, specification that the study medication had to be administered with the same infusion rate as used during the first infusion (20-30 minutes). - The original protocol specified that the efficacy analyses would be performed on the ITT population. A modification was made to specify that the primary efficacy analysis would be performed on the PP population and the secondary analysis on the ITT population since this is a more conservative approach for non-inferiority trials.
    15 Jan 2010
    - Based on the DSMB’s interim efficacy check of the data of 108 subjects with a treatment period of 6 months, this amendment specified that recruitment had been halted on 22 December 2009 and would not be re-started. The double-blind treatment period was prematurely terminated and study participants were offered a participation in an open treatment arm (follow-up period). All subjects were offered a treatment with the comparator drug (rFVIII-FS-POPC/rFVIII-FS-WFI) and/or open-label rFVIII-FS-WFI for 6 months or until completion of the 12-month total study duration. Participation was according to the subjects’ preference. This applied also to subjects who had not yet started the treatment phase. Blinding was to be preserved until clean data base of the blinded study. - The DSMB concluded that the study would not be able to establish non-inferiority of BAY79-4980 compared to the control treatment with a non-inferiority margin of 15% and recommended to halt recruitment. The sponsor decided to discontinue the investigational treatment and to guarantee the treatment of subjects until study completion or at least 6 months in the comparator arm.

    Interruptions (globally)

    Were there any global interruptions to the trial? Yes
    Date
    Interruption
    Restart date
    22 Dec 2009
    The recruitment and double-blind study phase were prematurely terminated after a scheduled interim analysis confirmed overt failure regarding the primary endpoint as judged by the independent DSMB.
