Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   38177   clinical trials with a EudraCT protocol, of which   6271   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To determine the efficacy of tasimelteon in subjects with N24HSWD as measured by the proportion of entrainment.

    (A step-down objective): To determine the efficacy of tasimelteon in subjects with N24HSWD as measured by the proportion of patients with a clinical response;
    Clinical response is defined as the coincident demonstration of :
    1.) Entrainment of the aMT6s rhythm, and
    2.) A score of ≥3 on the Non-24 Clinical Response Scale (N24CRS)

    The success of the trial will be based on the rejection of the null hypothesis associated with the proportion of entrainment as measured by aMT6s.
    E.2.2Secondary objectives of the trial
    Key Secondary Objectives
    • To determine the efficacy of tasimelteon in subjects with N24HSWD as measured by the proportion of responders with a combined sleep/wake response for nighttime sleep duration and daytime sleep duration defined as:
    1. Increase of 90 minutes or greater in LQ-nTST and
    2. Decrease of 90 minutes or greater in UQ-dTSD
    • To determine the efficacy of tasimelteon in subjects with N24HSWD as measured by the proportion of entrainment as assessed by urinary cortisol

    Additional Secondary Objectives: See protocol
    E.2.3Trial contains a sub-study Yes

    9. Diagnosis of N24HSWD as determined by:
    a. History (within the last 3 months) of trouble sleeping at night (difficulty initiating sleep or staying asleep), difficulty awakening in the morning, or daytime sleepiness as determined by answering yes to at least one question in the Sleep Complaint Questionnaire and
    b. Urinary aMT6s demonstrates a progressive delay of the aMT6 acrophase time.

    3. Subjects who take NSAIDs daily and would not interrupt their use for the 48-hour urine collections and the 24 hours preceding them;
    4. History of intolerance and/or hypersensitivity to melatonin or melatonin agonists;
    5. History of drug or alcohol abuse as defined in DSM-IV, Diagnostic Criteria for Drug and Alcohol Abuse, within the 12 months prior to screening and/or regular consumption of alcoholic drinks (> 2 drinks/day or > 14 drinks/week);
    a. Note: A standard drink is equal to 13.7 grams (0.6 ounces) of pure alcohol or
    o 12-ounces of beer
    o 8-ounces of malt liquor

    10. Clinically significant deviation from normal in clinical laboratory results, vital signs measurements, or physical examination findings at screening or baseline as determined by the clinical investigator;
    11. Indication of impaired liver function (values for AST, ALT or bilirubin > 2 times Upper Limit of Normal);
    12. Pregnant or lactating females;
    13. A positive test for drugs of abuse at the screening visit;
    Note: A positive drug screen at Visit 1 needs to be discussed with the medical monitor and will be evaluated on a case-by-case basis.
