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   44334   clinical trials with a EudraCT protocol, of which   7366   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
    To provide confirmatory data on the beneficial effect of 2.0 g/kg of Octagam 10% given every 4 weeks compared with placebo in subjects with active DM based on the percentage of responders at Week 16.
    Protection of trial subjects
    This trial was conducted in accordance to the principles of ICH- GCP, ensuring that the rights, safety and well-being of patients are protected and in consistency with the Declaration of Helsinki and national regulatory requirements. Inclusion and exclusion criteria were carefully defined in order to protect subjects from contraindications, interactions with other medication and risk factors associated with the investigational medicinal product. Study safety was assessed such as monitoring of AEs and SAEs, monitoring of safety lab results, concomitant medication and vital signs.

    Subjects received 4 infusions of placebo every 4 weeks during the blinded First Period (up to week 16). If confirmed deterioration (deterioration at 2 consecutive visits) during the First Period, subjects switched to Octagam 10%. After response assessment at Week 16, all subjects with no confirmed deterioration and subjects switched to Octagam 10% due to confirmed deterioration but without further confirmed deterioration during the First Period continued to receive 2.0 g/kg of Octagam 10% every 4 weeks during the subsequent 6-months open-label Extension Period. At Week 28, subjects who were stable on 2.0 g/kg Octagam 10% could be switched to 1.0 g/kg Octagam 10%, at the discretion of the investigator. Subjects randomized to placebo and switched to Octagam 10% due to confirmed deterioration, who deteriorated also during Octagam 10% treatment at 2 consecutive visits were droped-out after response assessment at Week 16 and did not enter the Extension Period.

    Proportion of Responders
    Statistical analysis description
    The primary endpoint measure ‘response’ was assessed at Week 16 based on the TIS score. The proportion of responders within both treatment groups was compared by the Cochran-Mantel-Haenszel test, stratified by GDA at baseline (randomization stratum), using a two-sided alpha level of 0.05. The primary analysis was to be considered a success if the proportion of responders was significantly higher in the octagam 10% group compared to the placebo group.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    07 Jul 2017
    Amendment 3: -Following a recommendation of the Steering Committee inclusion of patients with Dermatomyositis who are under no current treatment due to intolerance and/or non-responsiveness to DM-related medication has been added -upon recommendation by the Steering Committee exclusion criterion was amended to shorten the waiting period for patients after excision of basal or squamous cell skin cancer -Following a recommendation by the Steering Committee Subjects diagnosed with Juvenile Dermatomyositis were excluded from the study. - further specification of some exclusion criteria -Maximally allowed stable dose as concomitant therapy for Hydroxychloroquine was re-defined -in accoedance with the Steering Committee the definition of “Confirmed deterioration” was updated -As requested by the study’s Independent Adjudication Committee Thyroid-stimulating hormone (TSH) was added to the clinical chemistry test panel - Details on breaking the blind have been udated upon request of the Czech Regulatory Authority
    18 Jul 2018
    Amendment 4: -The maximum infusion rate has been reduced to 0.04 mL/kg/min upon request of FDA -Duration of infusion cycles for extension period changed from 2 days to 2-5 days -Upon FDA request a new stopping rule was implemented for TEEs observed on or after the cut-off date of 04-Jul-2018 (since introduction of reduced maximum infusion rate of 0.04 mL/kg/min) -Thromboembolic events will be reported as SAE (medical occurrence that at any dose is another important medical event) - Exclusion criterion with reference to forbidden medication has been added for clarification -Time window defined for Direct Coombs’ test taken prior infusion cycle has been extended for administrative reason
    05 Nov 2018
    Amendment 6: -Exclusion criterion was extended so that patients with any prior TEE event, regardless of the onset of the event, are not be eligible for participation in the study -References were added to explicitly state the higher risk for thromboembolic events in “newly” diagnosed patients with DM. -For the safety of patients with risk factors for thromboembolic events or patients who are in the initial disease stage after diagnosis the Permitted Concomitant Therapy Section has been amended wit the information that TEE prophylaxis, if deemed necessary by the investigator, is allowed as a precautionary measure and should follow standard of care. Its use must be documented.
    12 Mar 2019
    Amendment 7: Early Termination section has been updated based on the opinion of the IDMC. TEEs with a likely temporal and cause-effect relationship which occur in a single subject within a short clinical time period should be counted as a single adverse events of special interest (AESI) including for the calculations performed for stopping rules.
    03 Jul 2019
    Amendment 8: -As requested by FDA the definition of responders in study protocol was reworded and the primary endpoint was reworded subsequently in order to be unambiguous
