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   42869   clinical trials with a EudraCT protocol, of which   7063   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Main Study

Willingness & ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures
    2 Adult (males & females) aged 18-75 years (incl) with WHO Gp 1 PAH
    3 A current diagnosis of symptomatic PAH classified by one of the following:
    a Idiopathic or heritable PAH
    b PAH associated with one of the following connective tissue diseases:
    i Systemic sclerosis
    ii Rheumatoid arthritis
    iii Mixed CTD or overlap syndrome
    iv Systemic lupus erythematosus
    c PAH associated with anorexigen or methamphetamine use
    4 A WHO/NYHA functional class II–IV symptomatology
    5 Documentation of right heart catheterization prior to screening consistent with the diagnosis of PAH and meeting all following criteria:
    a Mean pulmonary arterial pressure (mPAP) ≥25 mmHg (at rest)
    b Pulmonary capillary wedge pressure (PCWP) ≤15 mmHg, or mean left atrial pressure (mLAP) or left ventricular-end diastolic pressure (LVEDP) ≤15 mmHg in the absence of left atrial obstruction
    c Pulmonary vascular resistance (PVR) ≥4 mmHg/L/min or 320 dyn×sec/cm5
    A qualifying cardiac catheterization is required during screening period if results of previous assessments are not documented
    6 Treatment with single or combination therapy from classes of phosphodiesterase type 5 (PDE-V) inhibitors, guanylate cyclase (GC) stimulators, endothelin receptor antagonists, and prostanoids including prostacyclins and small molecule prostacyclin receptor agonists, eg, selexipag (with exception of inhaled prostanoids) is allowed. For this study, single or combination therapy with one or more of these drugs is considered PAH background therapy. Subjects who are intolerant of all PAH background therapy may be allowed to be randomized on a case-by-case basis in consultation with the Medical Monitor. PAH background medications should remain stable and unchanged for the past 30 days prior to screening. In addition, diuretic doses should be stable for the past 30 days prior to Screening. Diuretics (as needed) for intermittent weight gain (if prescribed 30 or more days prior to screening and unchanged within 30 days prior to Screening) will be considered a stable dose for this study.

    8 Body weight >40 kg at screening
    9 6 Minute Walk Test (6MWT) distance >100 m at screening; if distance walked is not >100 m, test may be repeated once; the distance walked during second assessment must be >100 m, with test conducted on a separate day)
    10 No evidence of CTEPH or acute pulmonary embolism as assessed by ventilation-perfusion (V/Q) lung scan, CT-angiogram, or pulmonary angiogram (i.e., should note “normal” or “low probability” for pulmonary embolism) prior to screening, or at screening if: a) not performed prior or b) if clinical course suggests possibility of a pulmonary embolus as determined by the principal investigator since the last time study was performed
    11 Women of childbearing potential must use one contraceptive method (one additional non hormonal contraceptive method if using combined hormonal contraceptive or progestogen-only hormonal contraceptive) that is highly effective (failure rate of <1% per year), preferably with low user dependency during the intervention period and for at least 28 days after the last dose of IP, and have a negative pregnancy test at Screening and Day 1. To be considered as “not of childbearing potential” females must be either: postmenopausal for at least 1 year as confirmed by an elevated FSH level (≥30 mIU/mL) at Screening and 1 year of amenorrhea OR have been irreversibly surgically sterilized by hysterectomy, oophorectomy, or bilateral tubal ligation at least 3 months prior to the first dose of IP. Men who are not sterile (ie, have not had a vasectomy) must also agree to use contraception and not donate sperm during the intervention period through at least 3 months after the last dose of IP
