Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   42758   clinical trials with a EudraCT protocol, of which   7042   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    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 aim of the trial is to assess whether the anticoagulant effects of rivaroxaban are not inferior to those of warfarin. This will be achieved by comparing the percentage change in endogenous thrombin potential (ETP), assessed by the thrombin generation test (TGT), from randomisation to day 42. The TGT is a global measure of anticoagulation, which can assess the anticoagulant effects of both rivaroxaban and warfarin (drugs with very different modes of action on the coagulation mechanism). The TGTs will be performed in the UCL Haemostasis Research Unit.
    E.2.2Secondary objectives of the trial
    1) To compare the effectiveness of the treatment between the two arms of the trial: i) Further blood clots in blood vessels (venous thromboembolism) ii) A combination of further venous thromboembolism and other thrombotic events 2) To compare serious adverse events and all bleeding events in patients on rivaroxaban versus those on warfarin 3) To compare the completed quality of life questionnaires at baseline and at day 180 for patients on rivaroxaban versus those on warfarin. 4) To assess compliance to the study drugs by performing assays in the plasma from the patients on rivaroxaban (anti-Xa assay) and in patients on warfarin (INR and factor X amidolytic assay as an antiphospholipid antibody-independent assessment of anticoagulation). Percentage time in therapeutic range (TTR) between baseline and day 180 will be calculated in patients on warfarin.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1) Patients with thrombotic APS, with or without SLE, who have had either a single episode of VTE whilst not on anticoagulation or recurrent episode(s) which occurred whilst off anticoagulation or on sub-therapeutic anticoagulant therapy 2) Patients with a target INR of 2.5 (range 2.0 – 3.0) 3) Treated with warfarin for a minimum period of six months since last VTE 4) Female patients must be using adequate contraception with exception to postmenopausal or sterilised women
    E.4Principal exclusion criteria
    1) Previous arterial thrombotic events due to APS 2) Recurrent venous thromboembolic events whilst on warfarin 3) Pregnant or lactating women 4) Severe renal impairment (creatinine clearance (calculated using the Cockcroft & Gault Equation Appendix A) < 30 mL/min (i.e. 29 mL/min or less)) 5) Liver function tests (ALT > 2 x ULN) 6) Thrombocytopenia (platelets < 75 x 10^9/L) 7) Non-compliance on warfarin (based on clinical assessment) 8) Patients on azole antifungals (e.g. ketoconazole, itraconazole, voriconazole and posaconazole) 9) Patents on Human Immunodeficiency Virus (HIV) protease inhibitors (e.g. ritonavir) 10) Patients on strong CYP3A4 inducers (e.g. rifampicin, phenytoin, carbamazepine or phenobarbital) 11) Patients less than 18 years of age
    E.5 End points
    E.5.1Primary end point(s)
    Percentage change in endogenous thrombin potential (ETP), assessed by the thrombin generation test (TGT), from randomisation to day 42.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The time point for the primary outcome is at the first trial visit, which will take place 42 days (±12days) after trial randomisation.
    E.5.2Secondary end point(s)
    a) Efficacy: i) recurrent venous thromboembolism (VTE) alone; ii) a composite of recurrent VTE and other thrombotic events. iii) The thrombin generation curve will also be quantified in terms of: the lag-time; the time to peak; and peak thrombin concentration. b) Safety: i) serious adverse events; ii) all bleeding events. c) Quality of life (QoL): EQ5D 5L. d) Laboratory assessment of compliance: i) anti-Xa assay in patients on rivaroxaban; ii) factor X amidolytic assay as an antiphospholipid antibody-independent assessment of anticoagulation, in addition to an International Normalised Ratio (INR) in patients on warfarin, iii) percentage time in therapeutic range (TTR) between baseline and day 180 in patients on warfarin.
    E.5.2.1Timepoint(s) of evaluation of this end point
    All bleeding and thrombotic events are going to be collected at each visit (day 42 (±12 days), day 90 (±21 days), day 180 (±21 days) and day 210 (±21 days)). Quality of life will be measured at baseline and at six months using the EQ 5D 5L questionnaire. Laboratory measures of compliance will be measured at day 42 (±12 days) on trial treatment.

    F.5 Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)
    After the interventional stage of the trial patients will be provided with the treatment that is considered appropriate care at the time. Rivaroxaban is licensed and commercially available for the treatment of deep vein thrombosis (DVT) and prevention of recurrent DVT and pulmonary embolism following acute DVT in adults. Therefore, although it would not be available via the trial, it will be available through private health care or may be available through the NHS
