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   43845   clinical trials with a EudraCT protocol, of which   7282   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.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of this study is to determine if darusentan is effective in
    reducing SBP and DBP in subjects who have RHTN, despite being treated with full
    doses of three or more antihypertensive drugs, including a diuretic.
    E.2.2Secondary objectives of the trial
    Secondary objectives of this study are to examine the effect of darusentan on mean
    24-hour ambulatory BP, percent of subjects meeting SBP goal, and eGFR. The safety
    and tolerability of the darusentan in the subject population will also be evaluated.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Subjects must be competent to provide written informed consent.
    2. Subjects must be 35-80 years of age.

    4. Subjects with diabetes and/or CKD must have an average sitting SBP ≥130 mmHg.
    5. All other subjects must have an average sitting SBP ≥140 mmHg.
    6. Subjects must be receiving, and adhering to, full doses of appropriate guideline-recommended antihypertensive drugs from three different classes of antihypertensive agents, including a diuretic.

    11. Subjects who have had a diagnosis or recurrence of malignancy within the past 3 years, with the exception of basal cell carcinoma of the skin or in situ carcinoma of the cervix.
    12. Subjects with sleep apnea are excluded, unless a post-treatment sleep study has confirmed treatment efficacy and there are no recordings of blood oxygen saturation (SpO2) <90% at any time during the testing period.
    13. Subjects who perform alternating shift or night work.
    14. Subjects treated with a central alpha-2 agonist and/or an imidazoline receptor agonist (i.e., guanfacine, clonidine, moxonidine) within 90 days of Screening.
    15. Subjects who have participated in a clinical study involving another investigational drug or device within 4 weeks of the Screening Visit (Visit 1).
    16. Subjects not on stable doses of all concomitant medications for a minimum of 4 weeks prior to Screening (Visit 1), and subjects treated with any protocol-specified prohibited medications (e.g. thiazolidinedione).
    E.5 End points
    E.5.1Primary end point(s)
    The co-primary endpoints are the change from baseline to Week 14 in trough sitting
    SBP and trough sitting DBP, as measured by sphygmomanometry.
