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   43851   clinical trials with a EudraCT protocol, of which   7283   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.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    -IHS criteria for trigeminal neuralgia to be used. The diagnosis must be verified by a member of the diagnostic sub-committee of the Data Monitoring Committee before the patient is entered into the study.
    -A diagnosis of trigeminal neuralgia - Pain must be unilateral, and characterized by brief electric shock-like pains, abrupt in onset and termination, limited to the distribution of one or more divisions of the trigeminal nerve. Pain is commonly evoked by trivial stimuli including washing, shaving, smoking, talking and/or brushing the teeth(trigger factors), and frequently occurs spontaneously. The attacks start and end rapidly. There is often no pain between each bout of pain and many bouts can occur every day. There is often a refractory period between attacks. Some patients may report some after pain after the severe pain for a few minutes. Pain remissions occur where there can be weeks or months of no pain even when medications are stopped.
    -The following diagnostic criteria for trigeminal neuralgia must be met:
    -Paroxysmal attacks of pain lasting from a fraction of a second to 2 minutes, affecting one or more divisions of the trigeminal nerve and fulfilling criteria b and c.
    -Pain has at least one of the following characteristics:
    i. Intense, sharp, superficial or stabbing
    ii. Precipitated from trigger areas or by trigger factors
    -Attacks are stereotyped in the individual patient
    -There is no clinically evident neurological deficit
    -Not attributed to another disorder
    -Frequency criteria for numbers of paroxysms:
    -Patients must have suffered a minimum of 3 or more paroxysms of pain per day, rated at an intensity of 4 or more on the pain NRS, on at least 4 days during the last 7 days prior to entry into the open-label treatment period.
    -Male or female between 18 and 80 years of age inclusive, at the time of signing the informed consent.
    -A female patient is eligible to participate if she is of:
    -Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) >/= 25.8 MlU/ml and estradiol < 40 pg/ml (<140 pmol/L) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods if they wish to continue their HRT during the study.
    -Child-bearing potential and agrees to use one of the contraception methods listed for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female patients must agree to use contraception until 3 days post-last dose.
    -Male patients must agree to use one of the contraception methods listed.
    This criterion must be followed from the time of the first dose of study medication until 14 days post-last dose.
    -Body weight >/=50 kg for men and >/=45 kg for women.
    -BMI </=34.9.
    -Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form. Informed consent must be obtained prior to the commencement of any study related procedures.
    -Three ECGs taken at least 5 min apart should be performed at Screening. QTcF < 450 msec in at least two of the three ECGs .
    -AST and ALT < 2xULN; alkaline phosphatase and bilirubin </=1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
    -Approved concomitant medications must have been stable for at least 3 weeks prior to day 0.
    -Se utilizarán los criterios de la Sociedad Internacional de Cefaleas (IHS, International Headache Society) para el diagnóstico de la neuralgia del trigémino. Un miembro del subcomité de diagnóstico del DMC deberá verificar el diagnóstico antes de que el paciente entre en el estudio.
    -Diagnóstico de neuralgia del trigémino. El dolor debe ser unilateral y se caracteriza por ser como una sacudida eléctrica de breve duración, que comienza y termina de manera abrupta, y se limita a la distribución de una o más ramas del trigémino. Por lo común, el dolor se desencadena con estímulos insignificantes, como lavarse, afeitarse, fumar, hablar o lavarse los dientes (factores desencadenantes), y con frecuencia se produce espontáneamente. Las crisis comienzan y terminan rápidamente. A menudo no hay dolor entre los episodios y pueden producirse numerosos episodios en un día. Con frecuencia hay un periodo refractario entre las crisis. Algunos pacientes refieren un dolor residual durante unos minutos después del dolor intenso. Se producen remisiones del dolor, de forma que pueden transcurrir semanas o meses sin dolor, incluso tras la suspensión de la medicación.

    The frequency and the severity of paroxysms will be recorded on a daily basis by the patient. The patient and clinical global impression of change rating will be determined on Day 21 and Day 49. The brief pain inventory - facial will be determined on Day 0, 21, 49 and 56. Pharmacokinetics will be assessed on Day 0, 7, 21, 35 and 49. Vital signs and ECGs will be assessed on Day 0, 7, 14, 21, 28, 35, 42, 49 and 56. Laboratory safety samples will be taken in screening and on Day 0, 7, 21, 35, 49 and 56. Cognitive status will be assessed on Day 0, 21 and 49. Adverse events profile scale will be determined in screening and on Day 21 and 49. Adverse events will be collected throughout.
