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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    Recruitment
    Recruitment details
    The study was conducted at 16 sites in Czech Republic, Denmark, France, Greece, Slovakia, Sweden, Hungary, and United Kingdom.

    Pre-assignment
    Screening details
    A total of 42 subjects were enrolled and treated in this study. Based on one year safety follow-up, subjects will be followed to Epoch 3 if anti-rHuPH20 antibody titer >= 160, and who experience either a related SAE or a related severe AE during Epoch 1 or Epoch 2. Data was reported based on interim analysis cut-off date (14-May-2020).

    Arm description
    Pediatric subjects with PIDD who were on non-HyQvia intravenous (IV) or subcutaneous (SC) treatment with immunoglobulin (IV-pretreated, SC-pretreated) were enrolled and treated with HyQvia (Immune Globulin Infusion 10% [Human] with Recombinant Human Hyaluronidase) SC with a dose or interval ramp-up period of up to 6 weeks. HyQvia was administered at a starting dose of 5 milliliter per hour per site (mL/h/site) to maximum tolerated dose of 80 mL/h/site (for subject with body weight [BW] < 40 kilogram [kg]) or starting dose of 10 mL/h/site to maximum tolerated dose of 240 mL/h/site (for subject with BW greater than or equal to [>=] 40 kg).

    Arm description
    Pediatric subjects who were treated with HyQvia prior to this study and those who completed the ramp-up period (Epoch 1) are followed by Epoch 2 with HyQvia treatment. After one year in Epoch 2, subjects with anti-rHuPH20 antibody titer <160 at all time-points during the study will complete the study termination/completion visit at the next possible occasion. Subjects with anti-rHuPH20 antibody titer >= 160 during the study and/or at the last measurement will continue for an additional two years of HyQvia treatment and observation. HyQvia was administered at a starting dose of 10 mL/h/site to maximum tolerated dose of 160 mL/h/site (for subject with body weight [BW] <40kg) or starting dose of 10 mL/h/site to maximum tolerated dose of 300 mL/h/site (for subject with BW >=40kg).

TEAE was defined as AEs with onset after date-time of first dose of IP, or medical conditions present prior to the start of IP but increased in severity or relationship after date-time of first dose of IP. Related AEs was defined as an AE that was recorded as “possibly related” or “probably related” to IP was considered “related AE”, and AE recorded as “unlikely related” or “not related” was considered “unrelated” AE.

    The Peds-QL was a generic HR QoL instrument designed specifically for a pediatric population. It captures the following domains: general health/activities, feelings/emotional, social functioning, school functioning. For this study, the Peds-QL for 8 to 18-year-old subjects was used. Higher scores indicate better quality of life (QOL) for all domains of the Peds-QL. This modular instrument uses a 5-point scale: from 0 (never) to 4 (almost always). Items are reversed scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, 4=0. 4 dimensions (physical, emotional, social, & school functioning) are scored.

    Pediatric subjects with PIDD who were on non-HyQvia intravenous (IV) or subcutaneous (SC) treatment with immunoglobulin (IV-pretreated, SC-pretreated) were enrolled and treated with HyQvia (Immune Globulin Infusion 10% [Human] with Recombinant Human Hyaluronidase) SC with a dose or interval ramp-up period of up to 6 weeks. HyQvia was administered at a starting dose of 5 milliliter per hour per site (mL/h/site) to maximum tolerated dose of 80 mL/h/site (for subject with body weight [BW] < 40 kilogram [kg]) or starting dose of 10 mL/h/site to maximum tolerated dose of 240 mL/h/site (for subject with BW greater than or equal to [>=] 40 kg).

    Reporting group title
    Epoch 2
    Reporting group description
    Pediatric subjects who were treated with HyQvia prior to this study and those who completed the ramp-up period (Epoch 1) are followed by Epoch 2 with HyQvia treatment. After one year in Epoch 2, subjects with anti-rHuPH20 antibody titer <160 at all time-points during the study will complete the study termination/completion visit at the next possible occasion. Subjects with anti-rHuPH20 antibody titer >= 160 during the study and/or at the last measurement will continue for an additional two years of HyQvia treatment and observation. HyQvia was administered at a starting dose of 10 mL/h/site to maximum tolerated dose of 160 mL/h/site (for subject with body weight [BW] <40kg) or starting dose of 10 mL/h/site to maximum tolerated dose of 300 mL/h/site (for subject with BW >=40kg).
