Official Title: A Phase III Case Series Clinical Study of the Reversal of the Anticoagulant Effects of Dabigatran by Intravenous Administration of 5.0g Idarucizumab (BI 655075) in Patients Treated Wtih Dabigatran Etexilate Who Have Uncontrolled Bleeding or Require Emergency Surgery or Procedures.RE-VERSE AD (A Study of the RE-VERSal Effects of Idarucizumab on Active Dabigatran) Trial

Further study details as provided by Boehringer Ingelheim:

Primary Outcome Measures:
  • Maximum reversal of anticoagulant effect of dabigatran based on central laboratory determination of dTT or ECT, at any time point from the end of the first infusion up to 4 hours after the last infusion. [ Time Frame: up to 4 hours ]

Secondary Outcome Measures:
  • Reversal of Activated Partial Thromboplastin Time (aPTT) [ Time Frame: up to 4 hours ]
  • Reversal of Thrombin Time (TT) [ Time Frame: up to 4 hours ]
  • Duration of reversal [ Time Frame: up to 24 hours ]
  • Occurrence of major bleeding (for group B only) intraoperatively and up to 24 hours post-surgery [ Time Frame: 24 hours ]
  • Time to cessation of bleeding (for Group A only) [ Time Frame: up to 24 hours ]
  • Minimum unbound sum (free) dabigatran [ Time Frame: up to 4 hours ]
  • Reversal of anticoagulation as measured by diluted Thrombin Time (dTT) or Ecarin Clotting Time (ECT) after the first infusion and before the start of the second [ Time Frame: up to 15 minutes ]

Accepts Healthy Volunteers:   No

Inclusion criteria:

  • Group A (Bleeding patients)

    • Overt bleeding judged by the physician to require a reversal agent
    • Currently taking dabigatran etexilate
    • At least 18 years of age
    • Written informed consent
  • Group B (Patients who are taking dabigatran who may not be bleeding, but do require an emergency surgery or procedure for a condition other than bleeding

    • Condition requiring emergency surgery or invasive procedure where adequate hemostasis is required. Emergency is defined as within the following 8 hours.
    • Current treatment with dabigatran
    • At least 18 years of age
    • Written Informed consent.

Exclusion criteria:

  • Group A (Bleeding Patients)

    • Patients with minor bleeds (epistaxis, hematuria) who can be managed with standard supportive care.
    • Patients with no clinical signs of bleeding
    • Contraindications to study medication including known hypersensitivity to the drug or its excipients.
  • Group B (Patients who require emergency surgery or procedure)

    • A surgery or procedure which is elective or where the risk of uncontrolled or unmanageable bleeding is low.
    • Contraindications to study medication including known hypersensitivity to the drug or its excipients (subjects with hereditary fructose intolerance may react to sorbitol).
