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   43974   clinical trials with a EudraCT protocol, of which   7312   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. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Subclinical hypothyroidism
    Subklinische hypothyreoidie
    E.1.1.1Medical condition in easily understood language
    Thyroid hormone has multiple actions. In subclinical hypothyroidism the thyroid gland is mildly underactive. This does not cause major symptoms, but may contribute to poor health in old age.
    Schildklier hormoon heeft vele functies. In SCH heeft de schildklier een licht vertraagde werking. Dit leidt niet to hevige symptomen, maar kan bijdragen tot een lagere gezondheid op hoge leeftijd.
    E.1.1.2Therapeutic area Diseases [C] - Hormonal diseases [C19]
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    1. Does Levothyroxine treatment for SCH give multi-modal benefits for the oldest old people with SCH?
    2. Are benefits seen across a wide range of outcomes, including prevention of cardiovascular disease, and improving health-related quality of life, muscle function and cognition?
    3. Are benefits seen in specific subgroups of oldest old people with SCH, including women, and those with mild degrees of SCH (TSH 4.6-10 mU/L)?
    4. Are any benefits offset by adverse effects, such as atrial fibrillation or heart failure?
    1. Leidt behandeling met levothyroxine tot multipele gezondheidsvoordelen in de oudste ouderen met subklinische hypothyreoidie?
    2. Zijn deze voordelen zichtbaar over een breed skala aan eindpunten, includief preventie van cardiovasculaire ziekte en verbetering van kwaliteit van leven, spierfunctie en congnitie?
    3. Worden de voordelen met name gezien binnen subgroepen van oudste ouderen, zoals vrouwen of ouderen met een milde subklinische hypothyreoidie (TSH 4.6-10 mU/L)
    4. Staan er tegenover de voordelen ook bijwerkingen, zoals boezemfibrilleren of hartfalen?
    E.2.2Secondary objectives of the trial
    i. To establish a strong national and interneational network of complementary research expertise in older people, including geriatric medicine, endocrinology and metabolic medicine, primary care, cardiovascular disease and biostatistics.
    ii. To link this research expertise with strong focus on patient perspective and needs.
    iii. To provide the necessary evidence to properly inform best practice for treatment of SCH in the oldest old.
    iv. To disseminate this evidence to health care practitioners and patients
    v. To improve clinical practice in management of SCH in the oldest old
    vi. To improve health and well-being of older people with SCH.
    vii. To establish a blood biobank, to be used in future research into causes and mechanisms of health, disease and disability in later life.
    viii. To establish experience in tailoring an RCT for the oldest old, to be used for future RCTs.
    i. Het opzetten van een sterk nationaal en internationaal netwerk van complementaire research exptertise in ouderen, waaronder geriatrie, endocrinologie en metabolisme, eerstelijnsgeneeskunde, cardiovasculaire ziekte en biostatistiek.
    ii. Het koppelen van deze kennis aan het perspectief en de wensen van ouderen patienten.
    iii. Het verschaffen van het benodigde bewijs voor 'best practice' voor de behandeling van SCH in de oudste ouderen.
    iv. Het dissemineren van dit bewijs naar gezondheidszorg professionals en patienten.
    v. Het verbeteren van de klinische beleid voor de oudste ouderen met SCH
    vi. Het verbeteren van de gezondheid en welzijn van de oudste ouderen.
    vii. Het opzetten van een bloed-biobank, om te gebruiken in toekomstig onderzoen naar de oorzaken en mechanismen van ziekte, gezondheid en afhankelijkeheid op hoge leeftijd.
    viii. Het verkrijgen van expertise in het op maat maken van een RCT voor oudste ouderen, te gebruiken in toekomstige RCT's.
