About this study

Official title: 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 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.

Conditions: Hemorrhage
Being tested: Idarucizumab
Medical subject headings: Hemorrhage

What is being measured

The primary outcome is the main question the study is designed to answer.

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

Secondary outcomes (15)

Measured: Up to 24 hours after the completion of the second infusion on Day 1 of the treatment period.
Number of Participants With Major Bleeding (for Group B Only) Intra-operatively and up to 24 Hours Post-surgery
Number of participants with major bleeding (for Group B only) intra-operatively and up to 24 hours post-surgery per International Society for Thrombosis and Hemostasis (ISTH) classification is reported.
Measured: Up to 24 hours post-surgery.
Minimum Unbound Sum Dabigatran Concentrations Since the End of First Infusion up to 4 Hours After the Completion of the Last Infusion (Cmin,1)

The 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 39.80 seconds.
Measured: 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 Anticoagulation as Measured by Thrombin Time (TT)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Idarucizumab in people with Hemorrhage, run by Boehringer Ingelheim at 13 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Aug 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03343704.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Feb 2025; AzTrials last refreshed its copy on 7 Nov 2026.
