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   36858   clinical trials with a EudraCT protocol, of which   6084   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
    The primary objective is the safety and tolerability of ambrisentan in the paediatric PAH population.
    E.2.2Secondary objectives of the trial
    Pharmacokinetics in the paediatric population:
    • Population pharmacokinetic assessment based on one plasma sample per subject at Weeks 4, 8, 12, 16, 20, and 24.
    • Pharmacokinetic/pharmacodynamic modelling.

    To obtain supportive efficacy data:
    • The change from baseline in the 6 minute walking distance (6MWD) test evaluated after 24 weeks of therapy.
    • Mean changes from baseline in the 6MWD test at Weeks 4, 8, 12, 16, and 20.
    • The time to clinical worsening of PAH.
    • The change from baseline in Subject Global Assessment to Week 24 using the SF-10 health survey for children.
    • The change from baseline in WHO functional class to Week 24.
    • Change from baseline in plasma brain natriuretic peptide (BNP or N-Terminal pro-B-type Natriuretic Peptide) concentration at Week 24.

    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Cardiopulmonary Hemodynamic Sub-study:
    Hemodynamic assessments will be performed at baseline and Week 24 or early withdrawal in a subgroup of subjects enrolled in centres where the collection of hemodynamic data is considered part of the standard of care.

    E.3Principal inclusion criteria
    1. Male or female at least 8 years of age and not yet 18 years of age at the time of randomization.
    2. A current diagnosis of PAH (WHO Group 1) with WHO class II or III symptoms in one of the following categories:
    • Idiopathic
    • Heritable [familial]
    • Secondary to connective tissue disease (e.g., limited scleroderma, diffuse scleroderma, mixed connective tissue disease (CTD), systemic lupus erythematosus, or overlap syndrome).
    • Persistent PAH despite surgical repair (at least 6 months prior to the screening visit) of atrial septal defects, ventricular septal defects, atrio-ventricular septal defects, and persistent patent ductus.
    3. Have met the following hemodynamic criteria for subjects with right heart catheterization (RHC) when performed as part of the diagnosis or routine care:
    • mean pulmonary arterial pressure (mPAP) of 25 mmHg
    • pulmonary vascular resistance (PVR) of 240 dynesec/cm5
    • left ventricular end diastolic pressure (LEVDP) or pulmonary capillary wedge pressure (PCWP) of ≤15 mmHg.
    4. Subjects must either be treatment naïve, have discontinued treatment with another ERA (e.g., bosentan) at least 1 month previously because of elevated liver function tests (LFTs), or have been on a stable dose of background treatment for PAH (e.g., sildenafil or prostacyclin) for at least one month prior to the Screening Visit. Background treatment for PAH, if any, should not change from the Screening Visit until the end of all Treatment Period assessments.
    5. Subjects who discontinued ERA treatment due to elevated LFTs, must have LFTs of <3 x Upper Limit of Normal (ULN).
    6. A female is eligible to participate in this study, as assessed by the investigator, if she is of:
    a. Non-childbearing potential (i.e., physiologically incapable of becoming pregnant); or,
    b. Child-bearing potential - has a negative pregnancy test and is not lactating at the Screening and Baseline/Randomisation Visits and agrees to use 2 reliable methods of contraception from the Screening Visit until study completion and for at least 30 days following the last dose of study drug (reliable methods of contraception are listed in Appendix 2.
    7. Subject or subject’s legal guardian is able and willing to give written informed consent. As part of the consent, female subjects of childbearing potential will be informed of the risk of teratogenicity and will need to be counselled in a developmentally appropriate manner on the importance of pregnancy prevention; and male subjects will need to be informed of potential risk of testicular tubular atrophy and aspermia.
    E.4Principal exclusion criteria
    1. Subjects currently taking an ERA.
    2. Subjects currently taking cyclosporine A.
    3. Subjects whose body weight is less than 20 Kg.
    4. Subjects who have not tolerated PAH therapy due to adverse effects which may be related to their mechanism of action (e.g., prostanoids, ERA, PDE-5 inhibitors) with the exception of liver abnormalities for those subjects who were receiving another ERA.
    5. Female subjects who are pregnant or breastfeeding.
    6. Subjects with diagnosis of active hepatitis (hepatitis B surface antibody and hepatitis C antibody), or clinically significant hepatic enzyme elevation (i.e., ALT, AST or AP >3xULN) at Screening.
    7. Subjects with severe renal impairment (creatinine clearance <30 mL/min) at Screening.
    8. Subject has clinically significant fluid retention in the opinion of the investigator.
    9. Subject has clinically significant anaemia in the opinion of the investigator.
    10. Subject has a known hypersensitivity to the study drug, the metabolites, or formulation excipients.
    11. Subjects who have participated in another trial or have taken another investigational product during the previous 30 days.
    12. Alcohol abuse, illicit drug use within 1 year.
    13. Any concurrent condition or concurrent use of medication that would affect subject safety in the opinion of the investigator.
    E.5 End points
    E.5.1Primary end point(s)
    Safety as assessed by:
    • Adverse Events.
    • Serious Adverse Events.
    • Clinical laboratory parameters.
    • Physical examination (Including height, weight, body mass index / body surface area, oxygen saturation, jugular venous pressure, liver size, and presence of peripheral oedema and/or ascites.)
    • Vital Signs.
    • Pubertal development (change from baseline in endocrinology assessments at Weeks 12 and 24).
