Brief summary

The primary objective is to demonstrate reversal of the anticoagulant effect of dabigatran in patients treated with dabigatran etexilate who have uncontrolled or life-threatening bleeding requiring urgent intervention, and in patients treated with dabigatran etexilate who require emergency surgery or other invasive procedure. The secondary objectives are to assess the reduction or cessation of bleeding, evaluate the clinical outcomes, safety and the pharmacokinetics of dabigatran in the presence of idarucizumab.

Inclusion criteria

* ≥ 18 years at screening. * Male or female patients. Women of childbearing potential (WOCBP) and men able to father a child must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly.

OR * Group B: A condition requiring emergency surgery or invasive procedure where adequate hemostasis is required. Emergency is defined as within the following 8 hours.

Exclusion criteria

Group A: * Patients with minor bleeding (e.g. 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 (subjects with hereditary fructose intolerance may react to sorbitol).

Recruitment details

This study was to demonstrate the reversal of the anticoagulant effects of dabigatran by intravenous administration of idarucizumab in patients treated with dabigatran etexilate who had uncontrolled bleeding or required emergency surgery or procedures over treatment period of 1 day following by 30 days follow-up.

Pre-assignment details

All subjects were screened for eligibility prior to participation in the trial. Subjects attended a specialist site which ensured that they (the subjects) strictly met all inclusion and none of the exclusion criteria. Subjects were not to be allocated to a treatment group if any of the entry criteria were violated.

Participants by arm

ArmCount
Group A - Patients With Uncontrolled or Life-threatening Bleeding
Two vials of 2.5 grams (g) of idarucizumab (BI 655075) (Total: 5g) were administered via intravenous infusions once over a 1-day treatment period. Two vials of idarucizumab were administered no more than 15 minutes apart. Patients who were taking dabigatran etexilate and had uncontrolled or life-threatening bleeding requiring urgent medical or surgical intervention were included in this group.
13
Group B - Patients Not Bleeding But Requiring Emergency Surgery or Invasive Procedure
Two vials of 2.5 grams (g) of idarucizumab (BI 655075) (Total: 5g) were administered via intravenous infusions once over a 1-day treatment period. Two vials of idarucizumab were administered no more than 15 minutes apart. Patients included in this group were those who were taking dabigatran etexilate and may not be bleeding, but do require an emergency surgery or other invasive procedure for a condition other than bleeding, where therapeutic anticoagulation with dabigatran etexilate was undesirable.
