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   43861   clinical trials with a EudraCT protocol, of which   7284   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.

    General information about the trial
    Main objective of the trial
    i. Does Trientine lead to an improvement in high-energy phosphate metabolism (myocardial energetics, i.e. energy processing) in patients with HCM?
    Protection of trial subjects
    Patients may develop adverse effects whilst taking Trientine.These risks will be fully explained to patients before they decide to participate in the trial. After patients have completed this clinical study, Trientine will be discontinued. Although Trientine is a licensed medication, it may not be possible to prescribe it “offlabel”, even if some of the patients have benefited from it. This will be made clear to patients before they enrol in the trial. MRI scanning is a standard clinical imaging modality in every day clinical use and risks to study participants from MRI scanning are very small, provided they do not have any contraindications to MRI scanning (patients with contraindications to MRI scanning will be excluded). Echocardiography is a standard clinical imaging modality in every day clinical use.

    Arm description
    Patients will be supplied with Trientine tablets. The starting dose prescribed will be 600mg per day (taken as 300mg twice daily) for the first week, followed by 1200mg/day (taken as 600mg twice daily) thereafter under the direction of a medical doctor. The study doctor will contact each patient after 1 week to ensure they feel well enough to continue, and if they do, to remind them to increase their dose.

    Dosage and administration details
    Trientine dihydrochloride is a divalent copper selective chelator. It forms a stable complex with divalent copper. This complex is readily excreted by the kidney, increasing copper excretion. It also reduces intestinal absorption. Patients will be supplied with Trientine tablets. The starting dose prescribed will be 600mg per day (taken as 300mg twice daily) for the first week, followed by 1200mg/day (taken as 600mg twice daily) thereafter under the direction of a medical doctor. The study doctor will contact each patient after 1 week to ensure they feel well enough to continue, and if they do, to remind them to increase their dose.

    Patients will be supplied with Trientine tablets. The starting dose prescribed will be 600mg per day (taken as 300mg twice daily) for the first week, followed by 1200mg/day (taken as 600mg twice daily) thereafter under the direction of a medical doctor. The study doctor will contact each patient after 1 week to ensure they feel well enough to continue, and if they do, to remind them to increase their dose.
