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   43801   clinical trials with a EudraCT protocol, of which   7259   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.2 Objective of the trial
    E.2.1Main objective of the trial
    The main purpose of this study is to assess the efficacy and safety of BT595 in adult subjects with chronic ITP. The primary objective of the study is to determine the rate of subjects with a response. A response is defined as a platelet count of ≥30×109/L and at least a 2 fold increase of the baseline count, confirmed on at least 2 separate occasions at least 7 days apart, and the absence of bleeding.
    E.2.2Secondary objectives of the trial
    The secondary objective of this study, in addition to further efficacy assessments, is to evaluate the safety of BT595.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    a) Written informed consent obtained from subjects indicating that they understand the purpose of and procedures required for the study and are willing to participate
    b) Male or female, aged 18 through 75 years, inclusive
    c) Diagnosis of chronic ITP (>12 months’ duration), including diagnosis of refractory ITP, and as defined by the International Working Group (Rodeghiero et al, 2009), where ITP is described as an autoimmune disorder characterized by isolated thrombocytopenia in the absence of other causes or disorders that may be associated with thrombocytopenia
    d) Treatment is indicated because of a high risk of bleeding or a need to raise the platelet count
    e) Mean screening platelet count of <30×109/L from 3 qualifying platelet counts performed within approximately 7 to 14 days before the start of treatment, with no individual platelet count above 35×109/L. The subject may be rescreened if the mean screening platelet count is ≥30×109/L (Note: If a subject is rescreened, all screening laboratory tests must be repeated. Note for Czech Republic: Rescreening can be performed only once).
    E.4Principal exclusion criteria
    a) Pregnancy or unreliable contraceptive measures or lactation period (females only)
    b) Known intolerance to immunoglobulins or comparable substances (e.g., vaccination reaction)
    c) Known intolerance to proteins of human origin or known allergic reactions to components of the study product
    d) Participation in another clinical study within 90 days before entering the study or during the study and/or previous participation in this study
    e) Employee or direct relative of an employee of the contract research organization, the study site, or Biotest
    f) Secondary thrombocytopenia or acquired medical conditions known to be associated with secondary thrombocytopenia, such as chronic lymphocytic leukemia; lymphoma; multiple myeloma; thyroid disease; or other forms of thrombocytopenia, such as drug induced thrombocytopenia; cirrhotic liver diseases; antiphospholipid syndrome; environmental thrombocytopenia; and bone marrow diseases
    g) Severe concomitant diseases that in the judgment of the investigator will interfere with the study, such as autoimmune hemolytic anemia, acute renal failure, and noncontrolled arterial hypertension
    h) Laboratory findings (e.g., abnormal laboratory values for hemoglobin, transaminase levels [alanine aminotransferase, aspartate aminotransferase], total bilirubin, creatinine, blood urea nitrogen, and immunoglobulins G, A, M) that preclude participation
    i) Positive Coombs test (direct and indirect)
    j) Planned invasive procedures during the time frame of the study
    k) Maintenance therapy with intravenous immunoglobulins (IVIgs) or infusion of IVIgs within 3 months before start of the study
    l) Unresponsive to previous IVIg treatment
    m) Additional therapy with high dose corticosteroids (equivalent to >30 mg prednisone/day), thrombopoietin receptor agonists, and/or immunosuppressives and/or other therapies (e.g., infusion of platelets) within 1 month before the start of the study (Note: Subjects on stable doses of ITP active treatment must not have modified the dose in the preceding 2 weeks and must maintain their prestudy dose during the study. Corticosteroids should not be given as a premedication. Rescue therapy with short courses [i.e., 1 to 4 days] of high dose steroids and IVIgs are allowed up to 2 weeks before study inclusion.)
    n) History of thrombotic events (including myocardial infarction, cerebral vascular accident [including stroke], pulmonary embolism, and deep vein thrombosis) 6 months before treatment start with BT595 or the presence of significant risk factors for thrombotic events
    o) Therapy with live attenuated virus vaccines 3 months before start of the study
    p) Selective, absolute immunoglobulin A (IgA) deficiency or known antibodies to IgA
