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   44334   clinical trials with a EudraCT protocol, of which   7366   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 Objective of the trial
    E.2.1Main objective of the trial
    The over-aching hypothesis is that there is a subgroup of patients, identifiable by genotype, with pulmonary arterial hypertension that will benefit from a safe and tolerated dose of Imatinib.

    Imatinib is thought to work by blocking a protein called platelet derived growth factor receptor B. There is a gene that regulates the blood levels of this protein, called the “PDGFRB”. Patients can be divided into 3 groups based on variants of this PDGFRB gene; the 3 groups are called CC, CT and TT. Patients with CC have higher levels of PDGFRB than patients with TT. It is possible that Imatinib works better in patients with CC than TT, and that patients who are in the CT group lie in between.

    The study has two parts.

    Part 1 will identify a maximum tolerated dose (MTD) of Imatinib in patients with pulmonary arterial hypertension. The MTD is defined by a dose with a 20% probability of leading to discontinuation of treatment for more than 5 consecutive days due to side effects.

    Part 2 will ev
    E.2.2Secondary objectives of the trial
    -Change in the six-minute walk test, a measure of exercise capacity
    -Change in echocardiogram (type of ultrasound heart test) values, a measure of how well the heart is working
    -Change in "BNP" blood test values, another measure of heart function
    -Change in Quality of Life scores

    The above refer to change from baseline at 24 weeks.

    From a statistical point of view, the study has two parts.

    Part 1: Discontinuation of the drug for more than 5 consecutive days due to Grade 2 or above Adverse Events defined by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (version .5.0, 2017), adapted for this study

    Part 2: The primary efficacy endpoint is a binary variable. For patients with a baseline PVR >1000 dynes·s·cm−5, success is defined by an absolute reduction in PVR of ≥300 dynes·s·cm−5 at 24 weeks. For patients with a baseline PVR ≤1000 dynes·s·cm−5, success is a 30% reduction in PVR at 24 weeks.

    At Week 28 ±3 days (or 4 weeks after early termination), subjects will have a televisit. Patients will be off study drug for approx. 4 weeks. Concomitant medications and AEs will be recorded. Women of childbearing potential will have a urine pregnancy test at home. Patients who wish to continue having the IMP will be able to discuss this with their study doctor. Treatment beyond the 28-week period will lie under the PI and local hospital’s responsibilities and will not relate to the study.
