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   43800   clinical trials with a EudraCT protocol, of which   7272   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.

    4. Have a diagnosis of TMA in accordance with one of the following three categories:
    • Primary aHUS, diagnosed clinically and having ADAMTS13 activity >10% in plasma. Patients are eligible with or without a documented complement mutation or anti-CFH antibody. Patients are categorized according to their response to plasma therapy (plasma exchange or plasma infusion):
    o Plasma therapy-resistant aHUS patients must have all of the following: 1) screening platelet count < 150,000/μL despite at least four plasma therapy treatments prior to screening; 2) evidence of microangiopathic hemolysis (presence of schistocytes, serum lactate dehydrogenase (LDH) > upper limit of normal (ULN), or haptoglobin < LLN); and 3) serum creatinine > ULN.
    o Chronic plasma therapy-responsive aHUS patients (plasma therapy-sensitive) must require at least once-per-week plasma therapy for four weeks before first dose of OMS721 with serum creatinine >ULN.
    • TTP defined as having all of the following:
    o Platelet count < 150,000/μL
    o Evidence of microangiopathic hemolysis (presence of schistocytes, serum LDH > ULN, or haptoglobin < LLN)
    o ADAMTS13 activity ≤ 10% during the current episode of TTP or historically
    • Persistent HSCT-associated TMA defined as having all of the following at least two weeks following modification or discontinuation of calcineurin inhibitor treatment or at least 30 days after the transplant:
    o Platelet count < 150,000/μL
    o Evidence of microangiopathic hemolysis (presence of schistocytes, serum LDH > ULN, or haptoglobin < LLN)
    o Renal dysfunction (doubling of serum creatinine from pre-transplant).
    5. No clinically apparent alternative explanation for thrombocytopenia and anemia.
    6. If sexually active and of childbearing potential, must agree to practice a highly effective method of birth control until the end of the study, defined as one that results in a low failure rate (i.e., less than 1% per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptives, some intrauterine devices, sexual abstinence or vasectomized partner.

    Subjects will be excluded from the study for any of the following reasons:
    1. Had eculizumab therapy within three months prior to screening.
    2. Have STEC-HUS.

    6. Baseline QTcF > 470 milliseconds.
    7. Have malignant hypertension (diastolic blood pressure [BP] > 120 mm Hg with bilateral hemorrhages or “cotton-wool” exudates on funduscopic examination).
