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   42782   clinical trials with a EudraCT protocol, of which   7047   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 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the acute hemodynamic study is to collect data about the drug effect on the right heart hemodynamic parameters (pulmonary vascular resistance (PVR), systemic vascular resistance (SVR) and PVR/SVR) measured by right heart catherization after single oral dose administration of NS-304.
    The primary objective of the double-blind study is a proof-of-concept assessment of the efficacy of NS-304 in subjects with pulmonary arterial hypertension (PAH) by measuring the change from baseline in the PVR at week 17 compared to placebo.
    E.2.2Secondary objectives of the trial
    The secondary objective of the hemodynamic study is to assess safety and tolerability of single oral dose of NS-304.
    The secondary objective of the double-blind study are:
    - assessments of preliminary efficacy of NS-304 regarding the following variables: 6-minutes walk test (6MWT), proportion of subjects with aggravation of PAH, right heart catherization parameters other than PVR

    Further objectives of the double-blind study are assessments of preliminary efficacy of NS-304 regarding the following variables: New York Heart Association (NYHA) functional class, borg dyspnoea score, plasma NT pro-brain natriuretic peptide (NT pro BNP) concentrations, echocardiographic parameters.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Male and female subjects 18 years of age or older with symptomatic PAH despite treatment with anticoagulants, calcium channel blockers, diuretics, cardiac glycosides, supplemental oxygen, endothelin-receptor antagonists and/or phosphodiesterase inhibitors. Endothelin receptor antagonists and phosphodiesterase inhibitors must have been used at a stable dose for more than 12 weeks before screening.
    2. Subjects with idiopathic PAH, familial pulmonary arterial hypertension and PAH associated with collagen vascular disease, corrected congenital vitium (congenital systemic to pulmonary shunts surgically repaired at least five years before) or anorexigen use.
    3. Diagnosis of PAH established according to the standard criteria:
    a. Resting mean pulmonary arterial pressure > 25 mmHg.
    b. PVR > 240 dynes s/cm5.
    c. Pulmonary capillary wedge pressure or left ventricular end diastolic pressure < 15 mmHg.
    4. PVR > 400 dynes s/cm5.
    5. Two 6MWTs between 150 and 500 m (inclusive) with the variation in 6MWT within ± 15% between the two tests despite other treatments for PAH.
    – Two 6MWT values are needed. Only one 6MWT should be performed at screening for confirmation of eligibility if 6MWT has been previously conducted within six weeks of the screening visit unless the subject was taking another investigational drug or participating in a specific training and exercise programme at the time of the previous test.
    6. Subjects who are willing and able to refrain from sunbathing, prolonged sun exposure and artificial sunlight exposure such as solarium use or UVA/UVB treatment, and to limit skin and eye exposure to sunlight using appropriate precautions (protective clothing, sunscreen and sunglasses) from the first dose until 14 days after study drug discontinuation.
    E.4Principal exclusion criteria
    Subjects will not be entered in the study for any of the following reasons:
    1. Subjects with clinically unstable right heart failure within the last three months (NYHA Class IV).
    2. Subjects who have received or have been scheduled to receive long-term treatment with epoprostenol within three months before screening.
    3. Hypotensive subjects (systemic systolic blood pressure < 85 mmHg).
    4. Subjects with PAH associated with portal hypertension, Human Immunodeficiency Virus infection or unrepaired congenital systemic to pulmonary shunts.
    5. Subjects with ventilation-perfusion lung scan or pulmonary angiography indicative of thromboembolic disease.
    6. Subjects with significant obstructive (forced expiratory volume in one second [FEV1]/forced vital capacity [FVC] < 70% predicted) or restrictive (total lung capacity < 70% predicted) lung disease.
    7. In collagen vascular diseases, subjects with significant interstitial disease (FVC < 70%).
    8. Subjects with evidence of left sided heart disease.
    9. Subjects with moderate or severe hepatic impairment (Child-Pugh B and C).
    10. Subjects with clinically significant chronic renal insufficiency (estimated creatinine clearance < 30 mL/minute, or serum creatinine > 2.5 mg/dL).
    11. Subjects who are receiving or have been receiving any investigational drugs within 30 days before screening.
    12. Subjects with musculoskeletal disorder limiting ambulation.
    13. females who are breast-feeding, pregnant or plan to become pregnant during the study and females who are not using a highly effective method of birth control (failure arte less than 1% per year) such as implants, injectables, combined oral contraceptives, some intra-uterine devices, sexual abstinence or vasectomized partner.
