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   38179   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.

    • Male or female aged between 18 and 80 years, with a diagnosis of trigeminal neuralgia:

    1. 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

    • Patients with a history or risk of seizures or a history of epilepsy, head injury or related neurological disorders
    • Patients with a history of uncontrolled or poorly controlled hypertension, with systolic BP frequently exceeding 160mmHg and/or diastolic BP frequently exceeding 100mmHg, or patients who have BP greater than or equal to 160mmHg systolic and/or greater than or equal to 100mmHg diastolic at screening after repeated measurements
    • History or presence of significant cardiovascular, gastro-intestinal, or renal disease or other condition known to interfere with the absorption, distribution, metabolism, or excretion of drugs.
    • Patients with conditions known to affect cardiac conduction or a personal or familial history of Brugada syndrome
    • Pregnant females or lactating females.
    • History or presence of any clinically significant abnormality in vital signs / ECG / laboratory tests or have any medical or psychiatric condition, which, in the opinion of the Investigator may interfere with the study procedures or compromise patient safety.
    • History of suicidal ideation and/or suicide attempts or clinical evidence of recent major depression.
    • Patients who are unable to maintain approved medications for their trigeminal neuralgia at a stable dose during the study.
    • Unable to refrain from excessive use of sedatives.
    • Unable to comply with the prohibited concomitant medication restrictions as detailed in the protocol. This includes but is not limited to sodium channel blockers or drugs that adversely interact with a monoamine oxidase-B inhibitor: MAOI’s, antidepressants, opioids and sympathomimetic agents.
    • History of hypersensitivity to CNV1014802.
    • The patient has participated in a clinical trial and has received an investigational product within 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer) prior to the start of this study.
    • Exposure to more than four new chemical entities (medications for which no marketing authorization has been obtained) within 12 months prior to the first dosing day.
    • Where participation in the study would result in total donation of blood or blood products in excess of 500mL within a 56 day period.
