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   43841   clinical trials with a EudraCT protocol, of which   7281   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.

    •Previously enrolled in B1321003, discontinued from the study after the Adjudication Committee granted Early Discontinuation due to the need to add or increase the dose of a chronic medication for worsening PAH, or
    •Completed B1321001 but unable to enroll in B1321003 or completed B1321003 study as planned
    2.Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.

    5.Women of childbearing potential must be using 2 forms of medically acceptable contraception (at least 1 barrier method), have a negative pregnancy test at Baseline/Day 1 and agree to use reliable methods of contraception for at least 1 month after the final study visit. Women who are surgically sterile or those who are post-menopausal for at least 2 years are not considered to be of childbearing potential.
    E.4Principal exclusion criteria
    1.Treated with an investigational drug (other than sitaxsentan or sildenafil in either B1321001 or B1321003) or device that has not received regulatory approval within the 30 days prior to Baseline/Day 1 or during the study.
    2.Is taking, or has an anticipated need for systemic administration (oral, intravenous (IV)) of cyclosporine A for the duration of the study.
    3.Is using chronic arginine supplementation including HeartBar®. This must have been stopped for at least 30 days prior to the first Screening day for B1321001.
    4.Has uncontrolled systemic hypertension as evidenced by sitting systolic blood pressure >160 mm Hg or sitting diastolic blood pressure >100 mm Hg at Baseline/Day 1.
    5.Has hypotension defined as systolic arterial pressure <90 mm Hg after sitting for 5 minutes at Baseline/Day 1.
    6.Has a history of portal hypertension or chronic liver disease, including hepatitis B and/or hepatitis C (with evidence of recent infection and/or active virus replication) defined as mild to severe hepatic impairment (Child-Pugh Class A-C).
    7.Has hepatic dysfunction, defined as aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) 1.5 times the upper limit of the normal (ULN) range or bilirubin >2 times the ULN range at Baseline/Day 1.
    8.Was discontinued from B1321003 due to AST or ALT >3 times upper limit of normal and a direct bilirubin >2 times the upper limit of normal; or AST or ALT >5 times the upper limit of normal.
    9.Has chronic renal insufficiency as defined by serum creatinine >2.5 mg/dL at first screening day for B1321001 or requires dialytic support.
    10.Has a hemoglobin concentration <10 g/dL at Baseline/Day 1.
    11.History of obstructive sleep apnea (treated or untreated).
    12.History of atrial septostomy.
    13.Has known hereditary degenerative retinal disorders (such as retinitis pigmentosa) or history of non-arteritic anterior ischaemic optic neuropathy.
    14.Has untreated proliferative diabetic retinopathy.
    15.Other severe acute or chronic medical or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
    16.Has a psychiatric, addictive or other disorder that compromises the ability to give informed consent for participating in this study. This includes subjects with a recent history of abusing alcohol or illicit drugs 30 days prior to the time of the first screening day for B1321001 and for the duration of the study.
