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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    Part I: Evaluate the effects of tiratricol treatment on neurodevelopment in young MCT8 deficiency patients, as measured by the Gross Motor Function Measure (GMFM-88) and Bayley Scales of Infant Development (BSID)-III Gross Motor Skill Domain.

    Part II: Evaluate the effects of long-term treatment (up to 4 years of total treatment) with tiratricol on neurodevelopment in young boys (≤30 months) with MCT8 deficiency, as measured by the Gross Motor Function Measure (GMFM)-88 and Bayley Scales of Infant Development (BSID)-III Gross Motor Skill Domain.
    E.2.2Secondary objectives of the trial
    Part I:
    1. Evaluate the effect of Tiratricol treatment at week 96 on specific motor development milestones.
    2. Evaluate the effect of tiratricol treatment on neurodevelopment in young MCT8 deficient patients as measured by the BSID-III.
    3. Evaluate the effect of tiratricol at week 96 on clinical and biochemical thyrotoxic features (serum T3 concentrations, tissue specific markers of thyroid hormone action).

    Part II:
    1. Evaluate the effect of long-term treatment (up to 4 years of total treatment) with tiratricol on specific motor development milestones.
    2. Evaluate the effect of long-term treatment (up to 4 years of total treatment) with tiratricol as measured by the BSID-III.
    3. Evaluate the long-term treatment effect (up to 4 years of total treatment) of tiratricol on clinical and biochemical thyrotoxic features (serum T3 concentrations, tissue specific markers of thyroid hormone action).
