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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    		 Aspirin 250 mg IV / 300 mg tablet
    Statistical analysis description
    Geometric means were compared using analysis of covariance (ANCOVA) models: baseline TXB2 values as covariate and use of concomitant treatment affecting the measurement up to the 5 minutes blood sample (yes/no), stratification by ST segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI)/unstable angina pectoris (UAP) at randomization as factors. Ratio of geometric means was obtained by exponentiating the differences in respective least squares (LS) mean estimates from the model.

    		 Incidence of the Composite Clinical Endpoint of Cardiovascular Death, Stroke and Myocardial Infarction up to Day 30 After Single Dose of Study Drug Administration
    End point description
    The occurrence of myocardial re/infarction (MI) was assessed up to and including the 30-day time point. Serial electrocardiograms (ECGs), creatine kinase (CKs) and/or creatine kinase-muscle-brains (CK-MBs) plus/minus (+/-) 2 hours*3 were obtained for each suspected recurrent ischemic event. Ischemic stroke (IS) is defined as a new, sudden focal neurological deficit resulting from a presumed cerebrovascular cause that is not reversible or results in death within 24 hours and is not due to a readily identifiable cause, such as a tumor or seizure. Composite number of subjects with cardiovascular (CV) death, IS and MI was reported.

    Differences in incidences and their 2-sided 95% CI and p-values were calculated by stratified Mantel-Haenszel method (strata: STEMI and NSTEMI/UAP). In case of zero event in a treatment group, the correction term 0.1 (correction type: group size) was applied. The study was not powered to show statistically significant differences between the treatment groups. Consequently, these analyses are regarded as exploratory analyses.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    30 Apr 2009
    1. Two inclusion criteria were added 2. Secondary efficacy and safety variables were added 3. Subjects were assigned to treatment groups using interactive voice response system (IVRS) 4. Blood samples for TXB2 analysis, serum prostacycline and platelet aggregation inhibition analysis were taken during screening period 5. Cardiovascular endpoints, stroke endpoints and hemorrhagic endpoints were appointed for confirmation by an Endpoint Adjudication Committee 6. The statistical model was ANCOVA for the analysis of the primary efficacy variable (log transformed). The ANCOVA models were stratified by region (China and Europe), by use of anticoagulant and by the stratification factor STEMI/NSTEMI and unstable angina from the randomization.
    03 Aug 2010
    It was decided to cancel the study in China and conduct it only in Germany. For this reason, the coordinating investigator was changed, the number of randomized subjects was reduced, and sample size calculations were modified accordingly. Stratification by region (China and Europe) was excluded from the planned primary and secondary efficacy analyses. Since randomization was no longer performed by Interactive Voice Response System, the method of assigning subjects to treatment was modified. Prior and concomitant medications not approved in Germany were excluded from the list of prior/concomitant therapy permitted for this study. Pregnancy test was excluded since pregnancy testing has not been routinely performed on sites. Central laboratory was not needed anymore for the purpose of the study and all laboratory evaluations were to be performed by the local laboratories. Furthermore, only local ECG performance and evaluations were to be performed. Other relevant changes included the following: 1. Addition of statements regarding none-specific gender distribution and treatment(s) following the end of the study 2.Elaboration of an inclusion criterion by adding a statement on subject’s capacity to consent prior enrollment 3. A new definition of the time between screening and randomization (that is, the time frame was changed from “no more than 2 hours” to “as short as possible”) 4. Definition for sufficiently reliable safety signal of clinical relevance regarding bleeding events was added 5. On study definition and definitions of populations for analysis were slightly modified.
    18 Oct 2011
    1. Change of one inclusion criterion to: Angina pectoris lasting for more than 20 minutes within the last 24 hours before study drug treatment (or equivalent acute symptoms such as increasing dyspnoea, diaphoresis, nausea, abdominal/epigastric pain, syncope, etc.) and at least one of the following: a. ECG changes suggestive for ischemia: ST elevation or T-wave change or ST depression, new or presumed left bundle-branch block, b. Elevated troponin T levels >0.01 nanogram per milliliter or any other elevated troponin levels according to local laboratory reference values, c. Risk factors for acute coronary syndrome such as known coronary artery disease, diabetes mellitus, impaired renal function, peripheral artery or cerebrovascular disease, current smoking. 2. Change of one exclusion criterion to: Stroke within 3 months prior to study drug treatment. 3. Deletion of the following exclusion criterion: Other anticoagulants in the last 5 days before study drug treatment. 4. Addition of the following exclusion criterion: Treatment with glycoprotein IIb/IIIa inhibitors within 48 hours prior to study drug treatment and before the 20 minutes blood samples for thromboxane, prostacyclin, and platelet aggregation measurements had been taken. In addition, an appropriate definition of the PD population for analysis was implemented and “haematology (full blood count)” was excluded from the safety laboratory assessments.
