NCT02913326

Brief Summary

This is a multi-center, prospective, international, randomized (1:1), open-label study with two parallel groups. This phase III study is planned to investigate the efficacy and safety of dabigatran etexilate versus dose-adjusted warfarin on a net clinical benefit endpoint of major bleeding (ISTH criteria) and new venous thrombotic event (VTE) (primary endpoint) with blinded endpoint adjudication.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Composite of Venous Thrombotic Event (VTE) or Major Bleeding Event (MBE) According to International Society on Thrombosis and Haemostasis (ISTH) Criteria in Full Observation Period.

    Composite of the percentage of participants with MBE according to ISTH criteria and VTE (recurring cerebral venous thrombosis (CVT); deep venous thrombosis (DVT) of any limb, pulmonary embolism (PE), splanchnic vein thrombosis) in full observation period. All components were adjudicated in a blinded manner. Major bleeds were defined according to the ISTH definition of a major bleed, as follows: * Symptomatic bleeding in a critical area or organ, such as intracranial, intraspinal, intraocular, retroperitoneal, intra-articular or pericardial, or intramuscular with compartment syndrome and/or * Bleeding associated with a reduction in haemoglobin of at least 2 grams/deciLitre (1.24 millimole/Litre) within 24 h, or leading to transfusion of 2 or more units of blood or packed cells and/or * Fatal bleed

    From first administration of trial medication until 6 days after last administration of trial medication, up to 25 weeks.

Secondary Outcomes (7)

  • Percentage of Participants With Recurring Cerebral Venous and Dural Sinus Thrombosis; DVT of Any Limb, PE or Splanchnic Vein Thrombosis in Full Observation Period

    From first administration of trial medication until 6 days after last administration of trial medication, up to 25 weeks.

  • Cerebral Venous Recanalisation as Measured by the Change in Number of Occluded Cerebral Veins and Sinuses at Week 24

    Baseline and week 24

  • Percentage of Participants With Major Bleeding According to ISTH Criteria in Full Observation Period

    From first administration of trial medication until 6 days after last administration of trial medication, up to 25 weeks.

  • Composite Endpoint of Percentage of Participants With New Intracranial Haemorrhage or Worsening of the Haemorrhagic Component of a Previous Lesion After up to 24 Weeks

    From first administration of trial medication until end of treatment visit, up to 24 weeks.

  • Percentage of Participants With Clinically Relevant Non-major Bleeding Events in Full Observation Period.

    From first administration of trial medication until 6 days after last administration of trial medication, up to 25 weeks.

Eligibility Criteria

Age18 Years - 78 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Written informed consent in accordance with International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines and local legislation and/or regulations
  • Confirmed diagnosis of Cerebral Venous or dural sinus thrombosis (CVT), with or without intracranial haemorrhage
  • Completion of anticoagulation therapy for 5-15 days which has been administered until randomisation; anticoagulation must include full-dose low molecular weight heparin or unfractionated heparin
  • Eligibility for treatment with an oral anticoagulant

You may not qualify if:

  • Planned surgical treatment for CVT
  • Conditions associated with increased risk of bleeding
  • History of symptomatic non-traumatic intracranial haemorrhage with risk of recurrence according to Investigator judgment
  • Treatment with an antithrombotic regimen for an indication other than CVT and requiring continuation of that treatment for the original diagnosis without change in the regimen
  • Severe renal impairment
  • Active liver disease
  • Pregnancy, nursing or planning to become pregnant while in the trial
