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   44043   clinical trials with a EudraCT protocol, of which   7319   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.1.2Classification code 10026829
    E.1.2Term Marfan's syndrome
    E.1.2System Organ Class 10010331 - Congenital, familial and genetic disorders
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the trial is to estimate the effects of allocation to irbesartan, or doxycycline, or a combination of both irbesartan and doxycycline, compared with placebo, on measures of elastic function of the aorta in people with the Marfan syndrome and enlargement of the aorta.
    E.2.2Secondary objectives of the trial
    In patients with the Marfan syndrome and enlargement of the aorta:

    1) To estimate the effects of allocation to these treatment strategies on:
    i. the size of the aorta
    ii. the size and function of the heart
    iii. blood test measures relevant to the Marfan syndrome

    2) To explore the safety and tolerability of irbesartan, of doxycycline and of a combination of both, compared to placebo. The trial is not intended to definitively evaluate these clinical outcomes.

    3) To explore the effect of irbesartan, of doxycycline and of a combination, on short-term rates of tearing of the aorta, death from cardiovascular cause, or need for cardiovascular surgery, compared to placebo. The trial is not intended to definitively evaluate these clinical outcomes
    E.2.3Trial contains a sub-study No
