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   43861   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    The co-primary objectives of the study were to determine the safety of BAX 855 based on the incidence of FVIII inhibitory antibody development and to determine the efficacy of BAX 855 based on annualized bleed rate (ABR) as determined by the development of spontaneous bleeds (bleeds not associated with trauma).
    Protection of trial subjects
    This study was conducted in accordance with the International Conference on Harmonisation Guideline for Good Clinical Practice E6 (ICH GCP, April 1996), Title 21 of the US Code of Federal Regulations (US CFR), the European Clinical Trial Directive (2001/20/EC and 2005/28/EC), and applicable national and local regulatory requirements.

    Inhibitory antibodies to Factor VIII was measured by the Nijmegen modification of the Bethesda assay. Inhibitors must be confirmed by 2 separate assessments within a 2 to 4 week period from the central laboratory. Safety analysis set (SAS) included all subjects with at least 1 BAX 855 infusion. The analysis included subjects that developed inhibitory antibodies to FVIII and subjects that did not develop inhibitory antibodies to FVIII and had 100 or more EDs to BAX 855 across all studies and a FVIII inhibitory test result after the 100th exposure day.

    		 Annualized Bleed Rate (ABR) - Spontaneous Bleeds [2]
    End point description
    The ABR was assessed based upon each individual bleeding episode. A bleeding episode was defined as subjective (pain consistent with a joint bleed) or objective evidence of bleeding which may or may not require treatment with FVIII. Bleeding episodes occurring at the same anatomical location with the same etiology within 24 hours (+/- 2 hours) of onset of the first episode, bleeding occurring at multiple locations related to the same injury was counted as a single bleeding episode. The ABR of spontaneous bleeds was reported separately for twice weekly, PK-t R, each of the every 5 days and every 7 days treatment regimens at the time of bleed. Here, FDR refers to fixed-dose regimen, PK-t R to PK-tailored regimen and "n" indicates the number of subjects evaluable for this endpoint. Full analysis set (FAS) included all subjects with at least 1 BAX 855 infusion. 99999 indicates the data was not calculated due to less number of subjects.

    		 BAX 855 Infusions Needed to Treat Bleeding Episodes
    End point description
    The BAX 855 infusions to treat each bleeding episode was determined by the subject, the subject’s caregiver, and/or investigator, and was based upon the subject’s response to treatment. A bleeding episode was defined as subjective (pain consistent with a joint bleed) or objective evidence of bleeding which may or may not require treatment with FVIII. Bleeding episodes occurring at the same anatomical location with the same etiology within 24 hours (+/- 2 hours) of onset of the first episode, bleeding occurring at multiple locations related to the same injury was counted as a single bleeding episode. FAS included all subjects with at least 1 BAX 855 infusion.

The score was determined as (mean score/5)*100 where mean score is the mean of the available results in the particular subscale. Higher scores on the Haemo-SYM indicate more severe symptoms. Therefore, negative change scores indicate that symptoms have improved. Here, "n" indicates the number of subjects evaluable for this endpoint.

The score for each domain is then to be transformed to a 0-100 range as [(actual raw score-lowest possible raw score)/possible raw score range]*100. Positive change scores indicate improved HRQoL. Here "n" indicates the number of subjects evaluable for this endpoint. FAS included all subjects with at least 1 BAX 855 infusion.

    		 Change From Baseline in Patient Reported Outcomes: Health-related Quality of Life (HRQoL): Pediatrics Quality of Life (PedsQL) Questionnaire [6]
    End point description
    HRQoL in subjects aged <14 years was measured using the PedsQL. It capture data for the following domains: physical functioning, emotional functioning, social functioning, school functioning, psychosocial functioning, physical health and a total score. Each question of the PedsQL was scored as Never: 100, almost never: 75, sometimes: 50, often: 25, almost always: 0. The mean of the individual question scores was calculated. Lower scores on the PedsQL indicating worse HRQoL. Here, FDR refers to fixed dose regimen, PK-t R refers to PK-tailored regimen and "n" indicates the number of subjects evaluable for this endpoint. FAS included all subjects with at least 1 BAX 855 infusion.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    02 Oct 2013
    - The timing of the first Follow-up visit changed from 1 month (+/- 2 weeks) to 6 weeks (- 1 or + 2 weeks). - Additional information was added to the description of the IP to more completely describe the BAX 855 molecule, the purpose of the study, how the data with BAX 855 be assessed in this study and the dosing rationale in this study. - The minimal duration of the washout period was changed to 72 hours to align with the pivotal study (Study 2012-003599-38) and to avoid additional risk of bleeding episodes. - A section on Treatment for Surgery or Dental Procedures was added to provide clarity on how subjects would be transferred to and from the surgery study (Study NCT01913405), what factor would be used, what and where the clinical data would be recorded. - A requirement for a 72-hour washout period before immunogenicity tests was added to implement the laboratory requirements and to avoid false results. - The level of detectable FVIII inhibitory antibodies determined by the central laboratory was changed to 0.4 Bethesda Units (BU) because the central laboratory was validated for this value. - To ensure safety and to be able to provide safety review data upon completion of the pivotal study, a safety review was added as planned interim analyses.
    23 May 2014
    - Primary study completion date and duration of subject participation to reach 100 EDs were adapted. - Instead of the rate of success of BAX 855 in the treatment of breakthrough bleeding episodes, an overall hemostatic efficacy rating was used. - Additional guidance was provided on the treatment of bleeding episodes and maintenance of hemostasis. - It was clarified that only BAX 855 would be used for the control of bleeding episodes. - The more general term PROs was introduced instead of HRQoL. - PROs were to be assessed every 6 months during the study, in addition to baseline and end of study visits. - The dose and dosage frequency of BAX 855 were revised. - The reference to male previously treated patients (PTPs) was removed (i.e., females could now be included). - The age limit was changed to <= 75 years at screening of the previous BAX 855 study for transitioning subjects. - BAX 855 naive subjects <6 years old needed to have >=50 documented EDs to plasma-derived FVIII. - The cut-off for detectable FVIII inhibitory antibodies was increased to >=0.6 BU from >=0.4 BU in alignment with other BAX 855 studies and to avoid the risk of false positive results at this low level given the assay variability. - BAX 855-naive subjects <12 years of age were not to be enrolled until enrollment in the BAX 855 pediatric PTP study in children aged <12 years (Study 2014-000742-30) had been completed.
