This Study Looks at the Effects of Idarucizumab in Patients Who Take Dabigatran and Need Emergency Surgery or Are Bleeding

February 10, 2025 updated by: Boehringer Ingelheim

A Phase III, Case Series Clinical Study of the Reversal of the Anticoagulant Effects of Dabigatran by Intravenous Administration of Idarucizumab (BI 655075) in Patients Treated With Dabigatran Etexilate Who Have Uncontrolled Bleeding or Require Emergency Surgery or Procedures.

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maximum Reversal of Anticoagulant Effect of Dabigatran Based on Central Laboratory Determination of Ecarin Clotting Time
Time Frame: From the end of first infusion up to 4 hours after the completion of the second infusion on Day 1 of the treatment period.

Maximum reversal of anticoagulant effect of dabigatran based on central laboratory determination of ecarin clotting time is reported.

The maximum reversal of anticoagulant effect of dabigatran is defined for patients with at least one post-dose coagulation test results and pre-dose result higher than 100% Upper limit of normal (ULN). Maximum reversal is calculated as 100% x (pre-dose value - post-dose value)/(pre-dose value - 100% ULN). If the calculated reversal is > 100, it was set to 100. 100% ULN is 41.26 seconds.

From the end of first infusion up to 4 hours after the completion of the second infusion on Day 1 of the treatment period.
Maximum Reversal of Anticoagulant Effect of Dabigatran Based on Central Laboratory Determination of Diluted Thrombin Time
Time Frame: From the end of first infusion up to 4 hours after the completion of the second infusion on Day 1 of the treatment period.

Maximum reversal of anticoagulant effect of dabigatran based on central laboratory determination of diluted thrombin time is reported.

The maximum reversal of anticoagulant effect of dabigatran is defined for patients with at least one post-dose coagulation test results and pre-dose result higher than 100% Upper limit of normal (ULN). Maximum reversal is calculated as 100% x (pre-dose value - post-dose value)/(pre-dose value - 100% ULN). If the calculated reversal is > 100, it was set to 100. 100% ULN is 35.54 seconds.

From the end of first infusion up to 4 hours after the completion of the second infusion on Day 1 of the treatment period.

NO

IPD Plan Description

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).

For more details refer to: https://www.mystudywindow.com/msw/datatransparency

IPD Sharing Time Frame

After structured results have been posted, all regulatory activities are completed in the US and EU for the product and indication, and after the primary manuscript has been accepted for publication.

IPD Sharing Access Criteria

For study documents - upon signing of a 'Document Sharing Agreement'. For study data - 1. after the submission and approval of the research proposal (checks will be performed by the sponsor and/or the independent review panel, including checking that the planned analysis does not compete with sponsor's publication plan); 2. and upon signing of a legal agreement.
